Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a crusher for a photographic processing composition container, and particularly to a photographic material suitable for crushing a used photographic processing composition container to obtain a high quality resin molding material. The present invention relates to a crusher for a container for a treatment composition.

[0002]

2. Description of the Related Art Conventionally, high-density polyethylene (HD) has been used as a processing liquid container for a photosensitive material processing device such as an automatic developing device.
PE, polyvinyl chloride resin (PVC), polyethylene terephthalate (PET) and other single-layer materials, nylon / polyethylene (NY / PE) and other multi-layer materials that can be blow molded or injection molded to provide a rigid liquid container. Had been used. This is to make it easy for the user to attach importance to the independence of the container, the liquid filling suitability in the factory or the liquid filling suitability to the processing tank, and further, the un regulation (export dangerous goods transportation regulation, that is, the drop strength at -18 ° C). It is possible to secure enough strength to deal with the regulations that take into account the regulations) and regulations on the transport of poisonous substances.

However, in the conventional rigid processing liquid container, the shape of the container is maintained even after the contents are emptied due to the rigidity, so that the user can perform the photographic processing. Difficult to crush when discarding the composition container,
There was a problem that collection was inconvenient.

In order to improve such problems, recently, various flexible containers mainly made of resin such as low density polyethylene (LDPE) have been developed. The inventors have also developed a container of this type and have previously proposed it (Japanese Patent Laid-Open No. 6-301189).

[0005]

At present, it cannot be said that the use of the resin including containers for photographic processing compositions made of these resins and the like as recycled products is wide, and a stable market is not secured. . That is, there has been a long-awaited demand for providing a recovery method that users can use with peace of mind and an economical and safe recycling method.

When a container for a photographic processing composition is to be recycled as a molding material for a resin product, if the container or the like is collected with the cap attached, a sorting work between the container and the cap becomes indispensable after the collection, but this sorting work is manually performed. However, there is a problem that the residual liquid of the treatment liquid may adhere to clothes and the body during the sorting, and the sorting operation is difficult to mechanize, and thus the recycling cost becomes high.
Furthermore, the containers actually used are usually attached with a label or the like for indicating the contents, and it is necessary to remove the label, which further increases the recycling cost. .

When the container for the photographic processing composition is used as the material for the resin molded product, the material for the resin molded product is colored by the photographic processing composition when the container for the photographic processing composition is cut and the like. Often it became difficult to reuse it.

For these reasons, conventionally, the recycling rate of cutting a container for a photographic processing agent into a molding material for a resin product has not been so high. However, the limited reuse of global resources is not limited to the field of photographic processing agent containers,
We must now seriously work in all fields and industries.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a container for a photographic processing composition for obtaining a pulverized product suitable for producing a high-quality recycled container. To provide a crusher.

[0010]

In order to achieve the above object, the invention according to claim 1 provides a blade for crushing a container provided inside a crusher main body having a screen, and a container or a crusher inside the crusher main body. And a spray nozzle for spraying water onto a container extending to the inside of the main body.

Further, in the invention according to claim 2, the blade for crushing the container is installed in a shaft provided inside the crusher main body, and a plurality of blades are installed at intervals in the circumferential direction of the shaft. It is characterized in that a rotary blade and a fixed blade having a blade tip at a position facing the blade tips of these rotary blades are provided.

Further, the invention according to claim 3 is characterized in that the rotary blade is installed in a state of being gradually eccentric with respect to the central axis of the shaft shaft along the axial direction thereof. Is characterized in that the spray nozzle is installed in the vicinity of a bent portion which is interposed in the middle of a chute for charging a container into the crusher.

[0013]

According to the invention described in claim 1, water is sprayed into a container inside the crusher main body or a container up to the inside of the crusher main body, and in this state, it is crushed by the crushing blade. Water, for example, when using a container for photographic processing composition as a container,
The photographic processing composition adhering to the container is removed and at the same time the heat generated during crushing is prevented and the crushed product is cooled so as not to curl. The crushed material generated in the crusher body is discharged into a basket shape through the screen. Therefore, the size of the crushed material can be adjusted by setting the diameter of the mesh of the screen.

According to the second aspect of the invention, the size of the pulverized material is selected by the gap between the plurality of rotary blades and the fixed blade.

According to the invention of claim 3, a rotary blade,
The gap between the fixed blade and the fixed blade is increased along the axial direction of the shaft, the size of the pulverized material is set by the pulverized portion at the position in the axial direction of the shaft, and the desired pulverized material is discharged from the screen. According to the invention described in 4, the container supplied to the chute is inverted or rotated in the vicinity of the bent portion, and water is sprayed on the entire outer surface of the container.

[0016]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a process chart showing an embodiment of the present invention. In FIG. 1, the container for photographic processing composition includes a collecting step 1, a crushing step 2, an alkali washing step 3, a spray washing step 4, a rough washing step 5, a neutralizing step 6, a finishing washing step 7, a dehydrating step 8, and a drying step.

In the recovery step 1, since the recovered container is finally formed into a container again and is reused, it is desirable to select and recover the same material. However, visually recognizing containers having the same shape but different materials alone requires considerable skill and is actually difficult.

For this reason, 1) In the case of containers of the same material, the same coloring agent is used as the molding material and the containers are colored in the same hue, and the containers of different materials are colored in different hues. , And each has a unique hue depending on the material,
Or 2) use the same container shape for containers of the same material,
Containers of different materials will have different shapes, and each container will have its own shape. 3) Further, predetermined markings may be applied to containers made of different materials. By the means as described above, it becomes easy to separately collect each different material. According to the means of 1) to 3), the type of each resin can be visually selected.
It is also possible to automate the selection of colors, shapes, markings, etc. by image processing.

When the collected container is crushed with the lid member attached to the container body, it is desirable that the container body and the lid member are made of the same resin material. In this case, the "material of the same resin" is more specifically a polymer having the same chemical composition, and more preferably a polymer having substantially the same grade. is there. Here, the same grade can be evaluated by polymer density, melt index, and the like.

It is more preferably within 10%, particularly preferably within ± 5%. Moreover, the same kind of various additives are preferably added to the resin.

As the container for the photographic processing composition applied to the present invention, a container having a structure whose volume can be easily reduced is particularly preferable. As such a container, a container having a flexible container body is preferable, and in this case, a flexible low density polyethylene (LDPE) is used as a material, and a container body having a bellows portion is preferable. is there. Further, when the container body and the lid member are made of different resin materials, it is desirable that the lid member has a function of being detached with one touch and the cap is automatically opened.

In the recovery step 1, the recovered container is
As shown in FIG. 2, the sorting table 20 sends the crusher 23. A large number of holes of about 30 to 50 mm are formed at equal intervals on the upper surface of the sorting table 20, an opening is formed on one side surface of the sorting table 20, and the belt conveyor 21 can move near the opening. Has become. At this time, small articles such as HOTICS that are hard to find with the naked eye are dropped from the holes formed in the sorting table 20 and sorted from the container.

The container is sent from the sorting table 20 to the crusher 23 through the upper chute 24 by the belt conveyor 21 having the anti-slip projections 22 formed at regular intervals in the flow direction. As shown in FIGS. 2 and 3 (a view of the upper chute 24 viewed from the belt conveyor 21 side), the upper chute 24 has a two-stage spray nozzle group 25 (each nozzle group has five spray nozzles in the figure). ) Is installed, and from this spray nozzle group 25 to the upper chute 2
4 is sprinkled in a falling container.

In this case, the container falling inside the upper chute 24 collides with the vicinity of the bent portion of the upper chute 24 and is inverted or substantially rotated, so that the spray water of the spray nozzle group 25 is sprayed on the entire outer surface of the container. It

The crusher 23 is mounted on a pedestal 26, and a pulley 33B rotates via a drive motor 33A, and a rotary blade (not shown) installed in the crusher 23 rotates in synchronization with this rotation to crush the crusher. The container loaded into the machine 23 is crushed. The container crushed by the crusher 23 becomes a crushed product (chip) and is stored in the cleaning basket mold 29 mounted on the roller conveyor 28 via the lower chute 27.

4 and 5 show a device for showing the inside of the crusher 23. 4 and 5, the crusher is provided with a semi-cylindrical upper lid 30, a semi-cylindrical screen 31 is provided on the lower side of the upper lid 30, and the upper lid 30 and the screen 31 form a cylindrical space portion. Is formed,
This space communicates with the lower chute 27.

At the center of this space, a shaft 32 is rotatably installed. This shaft 32 is a bearing 3
3 is supported by a drive motor 33 as shown in FIG.
It is adapted to rotate in conjunction with A and a pulley 33B which rotates via a belt. The shaft 32 has a projection 3 having a substantially square cross section at a predetermined interval along the axial direction.
5, the protrusions 35 are formed with step portions 36 on each of the four pieces, and the blade tips of the rotating blades 37 are slightly formed on the respective step portions 36 in the central axis direction of the shaft 32. It is fixed in an eccentric state.

Two fixed blades 38 are fixed to a fixed blade base 39 and a pedestal 40 so as to be parallel to the central axis of the shaft 32 at a predetermined interval in the circumferential direction of the upper lid 30 of the crusher 23. There is. Therefore, the distance between the blade edge of the rotary blade 37 and the blade edge of the fixed blade that rotate in the direction shown by the arrow in the figure gradually increases along the axial direction of the shaft 32. The screen 31 is fixed by a screen retainer 41, and the upper lid 30 is reinforced by an arc-shaped reinforcing plate 42.

In this crusher 23, as the shaft 32 rotates, the container sandwiched between the blade edge of the rotary blade 37 and the blade edge of the fixed blade 38 is crushed by both blades to form chips. Since the distance between the blade edge of the rotating blade 37 and the blade edge of the fixed blade 38 gradually increases along the axial direction of the shaft 32, the shape of the tip formed by crushing the container is the axial direction of the shaft 32. The size of the chips is selected according to the size of the mesh of the screen 31 while gradually moving while moving in the crusher 23, though it depends on the crushing position.

In the crushing process of the container in the crusher 23, the chips generated by the crushing of the container tend to be softened and curled by the heat generated during the crushing, but the chips are apt to be cooled by the water sprayed from the spray nozzle 25. Is less likely to be softened, curling of the chip can be prevented, the photographic processing composition is not enclosed in the curl, and therefore coloring due to the photographic processing composition can be prevented. Further, the water sprayed from the spray nozzle 25 removes the photographic processing composition adhering to the container, especially the sulfur oxides, so that the blade of the rotary blade 37 and the fixed blade 38
It is possible to prevent the occurrence of rust on the blade of the machine.

In the crushing process using such a crusher, it is desirable that the size of the screen of the crusher is about 5 mm to 15 mm. If the screen has a small diameter,
The amount of finely pulverized material increases, the heat generated by the pulverizer increases, the number of colored chips increases, and the quality of chips used as a molding material deteriorates. On the other hand, when the diameter of the screen is large, the number of fine chips is reduced, so that the heat generated by the crusher is reduced and the generation of colored chips is reduced. However, if the chips are large, the flow of chips after the next process will deteriorate,
There is a risk that the efficiency will decrease and the chips will not be able to be caught in the screw during the pelletizing process.

The amount of water sprayed from the spray nozzle 25 is arbitrarily selected according to the amount of the container charged into the crusher 23, that is, the amount of chips formed by the crusher.
About 0 to 20 l / min, preferably about 15 l / min is desirable. If the amount of water sprayed is too small, the photographic processing composition adhering to the container is not sufficiently removed, and the number of colored chips increases and the quality of the chips as a molded article material deteriorates.

On the other hand, when the amount of water sprayed from the spray nozzle 25 is large, the photographic processing composition adhering to the container can be removed efficiently and the generation of colored chips is reduced, but the amount of water sprayed is more than necessary. Doing is not economical. When the photographic processing composition is removed from the container by spraying water from the spray nozzle 25, the load of alkali cleaning in the next step is reduced and the processing cost is reduced.

Further, in the crushing step 2, when the label is attached to the container through the water-soluble glue, the spray nozzle 2
The water-soluble glue is softened by water sprayed from No. 5, and is crushed (the label is rubbed) in this state, so that the label is easily peeled from the chip. It is desirable that the container is cooled before being introduced into the main body of the crusher. From this point, it is preferable to dispose the spray nozzle 25 on the upper chute 24. It may be provided near 30.

Next, the alkali cleaning step 3 is a step of surely removing the photographic processing composition from the chip and swelling (partially dissolving) the label to surely remove it. As the stirrer used in this alkaline step, a stirrer in which a basket-shaped container is rotatably installed is suitable, and particularly a stirrer in which a basket-shaped container having a rotating peripheral surface made of a punching plate can be installed is suitable.

The alkaline liquid used in the alkaline washing step 3 is not particularly limited, but NaOH is preferable in terms of cost and efficiency. As conditions for the alkali cleaning, in the case of NaOH, the concentration is about 5 to 15%,
It is preferably 8 to 10%. The concentration of NaOH is 5
If it is less than%, the cleaning effect of the container for the photographic processing composition is lowered, and the swelling (partially dissolving) effect of the label is lowered,
Further, even if the concentration is increased more than necessary, the cleaning effect is not improved, and considering safety, 10% or less is desirable.

The temperature in the alkali cleaning step 3 is 30.
~ 70 ° C, preferably about 50-60 ° C, and if the temperature is too low, the cleaning effect is reduced and the effect of swelling (partially dissolving) the label is reduced, while if the temperature is too high, Generation of gas increases, safety problems occur, and equipment measures such as exhaust gas countermeasures are required.

Next, the stirring time in the alkali cleaning step 3 is 40 to 80 minutes, preferably about 60 minutes. A stirring time of about 30 minutes is sufficient for removing the photographic processing composition adhering to the chips, but a stirring time of about 60 minutes is required for making the label fine by rubbing the chips. The rotation in stirring is 6 rpm to 10 rpm, preferably 8.5 rp
About m is desirable. If the number of rotations is low, the cleaning effect is reduced. On the other hand, if the number of rotations is high, liquid splash occurs and safety is impaired.

The alkaline liquid discharged from the stirrer in which the above-mentioned basket-shaped container is installed so that the eyes can be opened is collected in a dedicated pit, and the concentration of the collected liquid is measured by means such as a simple neutralization titration method. Based on the above, new NaOH is added to correct the concentration and then reused. By reusing the alkaline solution, it is sufficient to dispose of the alkaline solution once every 6 months to 1 year, and the disposal load (cost, working time, environmental pollution, etc.) is reduced.

By using this stirrer, the chips move in the basket-like container, and the chips rub against each other by this movement, so that the stirring efficiency becomes high. In addition, a stirring rod and a baffle plate for improving stirring efficiency are fixed in the basket-shaped container, and the label swollen (partially dissolved) on the surface of the chip is rubbed between the chips and the stirring rod and the stirring bar. Further, the jamming plate is rubbed into fine pieces, and the fine pieces are discharged to the outside from the holes formed on the surface of the basket-shaped container. Then, the label discharged from the stirrer is supplemented by a filter provided in the recovery route of the alkaline liquid and / or settles in the pit to be removed.

In the alkaline cleaning with the agitator described above, since the liquid in the cleaning tank can be exchanged in the basket-shaped container, the entire cleaning process can be performed, and the crushing process 2
Since the chips crushed in step 3 are placed in a basket-shaped container and can be moved as they are between the steps such as washing before the dehydration step, the handling of the chips is greatly improved.

The diameter of the holes formed in the punching plate of the stirrer is 1.5 mm to 2.5 mm, preferably 2.0.
About m is desirable. If the hole diameter is too large, the yield of washed chips will decrease, while if the hole diameter is too small,
The miniaturized label is less likely to be discharged from the basket-shaped container, the quality of the collected chips is deteriorated, and the chips may not be reused.

While the chips are stored in the basket-shaped container described above, the subsequent steps (spray washing step 4, rough washing step 5, neutralization step 6 and finishing step 7) are performed. In the washing process 4, water is sprayed for about 2 minutes by a hose or the like. By this operation, the alkaline liquid adhering to the cleaning tank is removed.

Next, in the rough cleaning step 5, the cleaning tank is filled with water, and the basket-shaped container is rotated for about 10 minutes to stir the inside of the basket-shaped container. By this step, it is possible to reduce the amount of the alkaline solution adhering to the chips, and to reduce the amount of H ₂ SO ₄ (sulfuric acid) used as a neutralizing agent in the neutralizing step 6 which is a subsequent step. By adopting this rough cleaning step 5, the amount of H ₂ SO ₄ (sulfuric acid) used can be reduced to about 1/10 as compared with the case without this step.

The neutralizing agent used in the neutralization step 6 is arbitrarily selected depending on the alkali used in the cleaning step 2,
From the viewpoint of efficiency and cost, H ₂ SO ₄ (sulfuric acid) is particularly preferable. By this neutralization step 6, the alkali attached to the surface of the chip is neutralized. In this neutralization step, for example,
About 1600 liters of water and about 1 liter of H ₂ SO ₄ are put in the washing tank, and a basket-shaped container with the chips stored therein is put in this washing tank and stirred for about 15 minutes. Low density polyethylene (LD
Since PE) tends to be weak against acid, it is desirable to set the shortest time necessary for neutralizing the alkali adhering to the chip.

Next, in the final cleaning step 7, the photoprocessing composition, alkali and acid still attached to the chips are removed to ensure the quality of the chips used as the molding material.
The condition of the finish cleaning step 7 is, for example, 160 in the cleaning tank.
Add about 0 liter of water, stir for 15 minutes, and perform this operation twice. Whether or not the photographic processing composition and alkali and acid have been sufficiently removed can be confirmed by measuring the electric conductivity of water discharged from the finishing cleaning tank and confirming that the value is equal to or less than a predetermined value. Desirably, if the electric conductivity at that time is, for example, 10 μs / cm or less, characteristics such as photographic properties are not hindered. The washing water used in this finishing washing step 7 is collected and used as water for sprinkling used in the crushing step 2 and washing water in the rough washing step 5.

In the series of steps from the alkali cleaning step 3 to the finish cleaning step 7, the work of each step is performed while the chips are stored in the basket-shaped container. As a result, the recycling work is simplified and the recycling cost is reduced.

Since the crushed material of different material is separated from the crushed material in the basket-shaped container after the finishing washing step 7, a specific gravity difference separation method can be adopted. By adopting this method, it becomes possible to use all the collected containers for the crushing process without selecting them. In this specific gravity difference separation method, it is preferable to select based on the difference in specific gravity between the liquid and the resin,
For example, low-density polyethylene (LDPE) has a specific gravity of 0.
92, high density polyethylene (HDPE) has a specific gravity of 0.9
If it is set to 6, LDPE can be used in a liquid with a specific gravity of 0.92 or more.
Since LD floats and HDPE sinks, LDPE and HDPE can be separated.

Further, by adopting the specific gravity difference separation method using the wind force sorter, it is possible to separate the resin chip, the label, the metal fine particles and the like which form the container. In a wind power separator, given a certain amount of wind force inside the sorter body, and throwing resin chips, labels and metal particles into the sorter body, the distance scattered by the wind force is different between the resin chips and the label due to the difference in specific gravity. Since the metal particles are different, it becomes possible to select the resin chip, the label, the metal particles, and the like.

Next, the dehydration step 8 reduces the drying load in the subsequent drying step. In the dehydration process 8, the basket type container containing the chips is set in the supply part of the continuous dehydrator, the lid of the basket type container is opened, and the chips in the basket type container are inserted into the screw part from the supply part of the dehydrator. Supply.

In the drying step 9, moisture is removed from the chips to ensure pelletizing and the quality of the molded product. From this point, it is desirable that the moisture in the chips be 0.5% or less. As a drying condition, it is effective to perform fluidized drying at a temperature of about 80 ° C. In the fluidized drying, the chips are dried in a fluidized state with warm air, so that the drying efficiency is good.

In the flexible container packing step 10, the dried chips are packed in a flexible container (flexible container) of a predetermined size to ensure storage / transportability. As the flexible container, about 1250 kg is preferable, and when the flexible container made of the same material as the chip is used, the chip can be pelletized as it is in the bag.

In the pelletizing step 11, the chips are formed into pellets of a fixed shape in order to make the resin flow constant during molding. As a molding machine, it is effective to use a ruder with a vent. By venting, water contained in the chips can be removed, and high quality pellets can be obtained. The extruder preferably has an extrusion rate of about 180 kg / hr, and it is desirable to remove dust and the like adhering to the chips with a screen of 150 μ × 2 and a screen of 80 μ × 2.

Next, in the molding step 12, a container for final purpose is molded. 100% recycled products in this process
Although it is possible to mold by using the virgin material (new molding material) and the recycled material, it is desirable to prepare a molded product because the quality of the crushed material may be deteriorated depending on the number of times of recycling. . In this case, the blend ratio of the virgin material and the recycled material is preferably 50% or less of the blended material of the recycled material. Further, if necessary, a predetermined amount of a heat stabilizer (for example, an organic phosphorus compound) or a filler is added to the recycled material to reduce coloring due to the heat history given to the molding material at each molding. Become.

In the embodiment shown in FIG. 1 described above, the pulverized product was washed with an alkali and then neutralized with an acid. However, in the case of polyethylene terephthalate (PET), since it is a material relatively weak against alkali, It is advisable to avoid washing and wash with acid, and then wash with water.

When it is not necessary to remove the label, acid cleaning may have a cleaning effect depending on the type of photographic chemicals. That is, in general, photographic chemicals are divided into a plurality of parts to form a single product in order to make the photographic chemicals compact and stable for a long time and more stable (without deterioration of components) during transportation. Therefore, the individually divided parts are composed of various liquids such as acid and alkali. There are various substances that are attached and solidified when these various liquids are filled and used and collected.

Some of these deposits are easily dissolved in alkali and others are easily dissolved in acid. For example, there are a developing agent part for color chemicals, an acidic part for fixing solutions, and the like. In particular, in the case of an acidic part, even if an adhered substance is generated, it is often acidic in nature and highly soluble. In the case of these acid cleanings, H ₂ SO ₄ , HNO ₃ , HCl or the like can be used, but from the viewpoint of cost, H ₂ SO ₄ is preferable and the concentration is 5
About 10% is good.
