Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a conveyor and an improvement of a garbage composting apparatus equipped with the conveyor.

[0002]

[Prior Art] Without incinerating and landfilling garbage,
In recent years, a technique for reprocessing into compost to promote the effective use of resources has been actively studied, and for example, a continuous processing apparatus has been proposed in Japanese Patent Application Laid-Open No. 2000-107730, "A fermentation processing apparatus for garbage and the like". According to FIG. 1 of the publication, a first tank, a second tank, a third tank,
A large amount of garbage can be treated by performing water adjustment, fermentation, aging, and drying in the order of the tank, the fourth tank, and the fifth tank.

By the way, performing all of the processing steps in one container with a common entrance and exit is called "batch processing" and is suitable for small-quantity production. Processing is called "continuous" processing and is suitable for mass production. The device disclosed in the above publication is the latter.

[0006] As shown in FIG. 6 of the above-mentioned publication, the above-mentioned apparatus is provided with a stirring blade 4 inclined with respect to a plane perpendicular to the rotation axis.
By moving 1 as shown by the white arrow, the garbage is fed into the processing object transfer hole 18 as shown by the black arrow. According to FIG. 1 of the publication, the inclined stirring blades 41 can be regarded as a component of the conveyor. This conveyor can be classified as a screw conveyor.

[0005]

When the present inventors operated the apparatus disclosed in the above publication, the following problems occurred. In FIG. 2 of the above-mentioned publication, when the garbage is directed to the partition plate 17 at the back of the drawing (reference numeral 17 is considered to be missing) by the stirring means 15, the partition plate 17 excluding the holes 18, 18, 18 is removed. Since the garbage is blocked by the garbage, a large reaction force acts on the stirring means 15 toward the drawing side, and the trouble that the stirring means 15 is damaged frequently occurs.

[0007] It takes 7 to 14 days for composting garbage to be composted. Even if the garbage is repeatedly moved forward and backward, the feed rate must be extremely low.
If the material is sandwiched between the honey and the stirring means 15, the stirring means 15 is very likely to break.

Although the screw conveyor is suitable for moving the processed material relatively quickly, it can be said that the screw conveyor is not suitable for cases where the moving speed needs to be extremely slow, as in a garbage composting apparatus.

Further, the stirring blade 41 of the above publication is a horizontally long rectangular plate, and has a good stirring effect for its simple structure. However, since the stirring blade 41 is a rectangular plate, a reaction force is directly received from the processed material, and the trouble that the stirring blade 41 is bent or the stirring means is damaged occurs.

Accordingly, an object of the present invention is to provide a conveyor and a composting apparatus having a structure capable of solving the above problems.

[0010]

According to a first aspect of the present invention, there is provided a conveyor comprising a plurality of pins or a plurality of rods having a rectangular cross section extending in a plane perpendicular to the rotation axis, the plurality of pins or the plurality of rods being spirally connected to the rotation axis.

[0012]

[0013]

[0014] composter according to claim 2, claim 1
A serial mounting of conveyor stirring and moving means, the food waste was introduced from one oblong tank, appropriate stirring forward-reverse is allowed if it fermentation, aging, drying, that can be taken out as a compost from the other tank Features.

By employing a pin conveyor, garbage can be moved back and forth at a very low speed. The garbage can be crushed with a pin or a stick. Therefore, according to the second aspect, it is not necessary to perform a crushing treatment before putting into a device, and a granular compost can be produced.

A garbage composting device according to a third aspect of the present invention is provided with a stirring blade extending parallel to a rotation axis at a tip of a pin or a rod.
It is characterized in that the stirring blade is made of a V-shaped cross-section member that is convex toward the rotation axis.

By forming the V-shaped cross section, the processed material flows on the slope of the V, and as a result, the resistance acting on the stirring blade can be reduced, and damage to the stirring blade can be avoided.

According to a fourth aspect of the present invention, in the garbage composting apparatus, the V-shaped cross-section member is constituted by two arc-shaped cross-section members and is formed in a human shape.

If the slope through which the processed material flows is depressed to form an arc, the resistance can be reduced in the first half of the arc and the stirring resistance can be increased in the second half of the arc. As a result, a moderate reduction in the stirring resistance and an appropriate amount of stirring can be achieved. Ensuring stirring performance is obtained.

[0020]

Embodiments of the present invention will be described below with reference to the accompanying drawings. The conveyor according to claim 1 is shown in FIG. 5, but for convenience, the garbage composting device will be described first. FIG. 1 is a side sectional view of a garbage composting device according to the present invention, and a garbage composting device 10 includes a horizontally long treatment tank 11.
Is divided by four partition plates 12, 13, 14, and 15, so that the pre-tank 16, the first tank 17, the second tank 18, and the third tank 1
9, divided into a fourth tank 20 and a long and thick rotating shaft 22 in each tank.
And the rotating shaft 22 is connected to the left and right two bearings 23, 2
3, one end of the rotating shaft 22 is driven by the electric motor 24 with a speed reducer, and the rotating shaft 22 is provided with first to sixth members 31 to 36 that exhibit a stirring / feeding action. This is an apparatus in which a filter 26, a blower 27, a catalyst and a deodorizer with a heater 28 are arranged in an exhaust system. That is, the rotating shaft 22 and the first member 3
The conveyor 30 is constituted by the first to sixth members 36.

The garbage is thrown into the pre-tank 16 from the inlet 38 indicated by the imaginary line, and is moved under the partition plate 12 to the first tank 17 and over the partition plate 13 to the second tank 18 for partitioning. The plate 14 is sunk and transferred to the third tank 19, the partition plate 15 is moved over to the fourth tank 20, and the outlet 39 indicated by an imaginary line is taken out.
This is a processing device that can be taken out of the plant in the form of compost.

The processing time is about 10 days. In the meantime, in order to keep the processed material (garbage) between the pre-tank 16 to the fourth tank 20, it is necessary to repeat the processed material forward and backward on the conveyor 30 at a very low speed. Special conveyor 3 developed for that purpose
0 will be described in detail in FIG.

The fermentation is performed between the pre-tank 16 and the fourth tank 20.
Aging and drying are performed, during which time an odor is generated. This malodor can be almost completely deodorized by the deodorizer 28 with a catalyst and a heater. The catalyst is preferably platinum (Pt).
Part of the deodorized air is released to the outdoors, and the rest is treated in the treatment tank 11.
Return to

FIG. 2 is a cross-sectional view of the garbage composting apparatus according to the present invention.
A space between the outer walls 43, 43 and the inner baths 41, comprising a V-shaped inner bath 41, a hot water jacket 42 covering the semicircular cross section from below, and outer walls 43, 43 and a bottom 44 covering the whole. Were filled with activated carbon 45, and the space between the bottom 44 and the hot water jacket 42 was filled with activated carbon 46. Activated carbons 45 and 46 are said to generate beneficial ions and thus have a favorable effect on the compost during production.

Further, hot water 47 of about 70 ° C. is constantly stored in the hot water jacket 42 to warm the inside of the inner tank 41. Fermentation proceeds by fermentation bacteria, and this progress can be promoted by keeping the temperature at about 70 ° C. The hot water system has the following advantages. Commonly used electric heaters and hot air heaters are easy to install and control. However, it was found that the so-called sharp (hard) heating resulted in uneven growth of the fermentation bacteria. In this regard, in the case of hot water, mild (soft) heating is performed, so that good growth of fermentation bacteria can be achieved.

In the figure, 48 is a lid corresponding to a valve, 38 is an inlet, and 49 is a temporary outlet. This temporary outlet 49
Use only when necessary.

FIG. 3 is an enlarged view of a main part of FIG.
FIG. 7 is an enlarged view of FIG. In the first tank 17 divided by the partition plate 12 and the partition plate 13, a set of six first members 31 to sixth members 36 is attached to the rotating shaft 22. For the sake of convenience, numerals 1 to 6 are added to each member. Another tank (second tank 1 in FIG. 1)
The same applies to the eighth to fourth tanks 20).

FIGS. 4A to 4F are views taken along arrows a to f in FIG. However, since the purpose is to represent the azimuth, the figure is simplified. (A) shows the first member 31. (B) shows the second member 32, and the second member 32 and the first member 31 form 120 °. (C)
The third member 33 is shown, and the third member 33 and the second member 32 form 120 °.

(D) shows the fourth member 34, and the fourth member 34 and the third member 33 form 60 °.
(E) shows the fifth member 35, and this fifth member 35
And the fourth member 34 make an angle of 120 °. (F) is the sixth
The member 36 is shown, and the sixth member 36 and the fifth member 3
5 is 120 °.

That is, the vertices of an equilateral triangle (△) having a pitch of 120 ° are formed by the tips of the first to third members 31, 32, and 33 shown in (a) to (c). (D) to (f)
The same applies to the fourth to sixth members 34, 35, and 36 shown in FIG. 7, but the distance between the third member 33 and the fourth member 34 is 60 °, which is a half pitch (half of 120 °). The distal ends of the members to the sixth to sixth members 34, 35, 36 form the vertices of an inverted regular triangle (▽) having a pitch of 120 °.

As a result, the sixth member 36 is located at the symmetric position of the first member 31 and the fourth member 36 is located at the symmetric position of the second member 32.
As with the member 34 and the fifth member 35 at the symmetrical position of the third member 33, the mass (mass) of the rotating shaft 22 is balanced, and the rotating torque of the rotating shaft 22 can be reduced.

FIG. 5 is a perspective view of the conveyor of the present invention.
The conveyor 30 has the shape of an ol gold ram in which the drum is replaced with the rotating shaft 22 and the pins are replaced with first to sixth members 31 to 36. The first member 31 to the sixth member 36 are pins or rods having a rectangular cross-section, which will be described later.
It is a type of screw conveyor that reverses and returns as shown by the arrow. For this purpose, a plurality of pins or a plurality of rods having a rectangular cross section are planted on the rotating shaft 22 along a spiral (not shown). Since the main element is a pin, it can be called a “pin conveyor”. .

Next, the points in which this pin conveyor is common to and different from ordinary screw conveyors will be described. FIG. 6 is an operation explanatory view of the conveyor of the present invention, and corresponds to a development view. The horizontal axis shows the positions of the first to sixth members, and the vertical axis shows the angle between the members. 1st member 31-
A solid line 51 connecting the third members 33 corresponds to a spiral, and it can be said that the first to third members 31 to 33 are arranged at a constant pitch on the spiral. When the rotation axis is rotated forward by 60 °, an imaginary line 52 is obtained.
The spiral moves up. Assuming that the spiral of the solid line 51 is made of a continuous plate (that is, screw blades), the processed material is outlined by an arrow F in the same manner as an ordinary screw conveyor.
You can move forward. This is a point common to the screw conveyor.

However, the transfer speed is too high.
Therefore, in the present invention, a continuous plate (screw blade) is not used, and a discontinuous pin or rod is used. That is, there is a large gap 53 between the first member 31 and the second member 32, and similarly, there is a large gap 54 between the second member 32 and the third member 33. Therefore, most of the processed material leaks from the gaps 54 and 55 like scooping sand with a net. As a result, the first member 31 to the third member 33 are reduced by a small amount.
To move forward. The same applies to the fourth member 34 to the sixth member 36.

Further, the first member 31 to the sixth member 3
It is important that a rectangular section extending in a plane perpendicular to the rotation axis (parallel to the vertical axis) without giving a pitch angle (twist) to 6 is used. Without the pitch, the first member 31 to the sixth member 36 alone cannot generate a thrust. However, such a first
By arranging the members 31 to the sixth member 36 on a spiral, a pin conveyor capable of feeding a very small amount is completed.

In summary, the first aspect of the present invention is to form an orgold ram shape by implanting a plurality of pins or a plurality of rods having a rectangular cross section extending in a plane perpendicular to the rotation axis on the rotation axis along a spiral. It is characterized by having done. In addition to replacing the screw blades with pins or rods, by not twisting the pins or rods, it was possible to complete an ultra-micro transfer conveyor.

Next, the reason why another half pitch is set only between the third member 33 and the fourth member 34 will be described. In FIG. 6, the mesh between the first member 31 to the third member 33 and the mesh between the fourth member 34 to the sixth member 36 can be regarded as a coarse mesh. On the other hand, the space between the third member 33 and the fourth member 34 can be regarded as a tight net. The force of sending the processed material as shown by the outlined arrow F is doubled in the closed net. In other words, a gentle slope at the ski resort (between the first member 31 and the third member 33).
There is a bump (between the third member 33 and the fourth member 34) between the sloping surface and the gentle slope (between the fourth member 34 and the sixth member 36). The bump shocks the processed material.

As a result of the experiment, FIG. 4 and FIG. 4 show that a half pitch member is interposed in the middle of a pin conveyor of equal pitch in which pins or rods are regularly arranged on a spiral which extends linearly without meandering. The unequal pitch pin conveyor shown in Fig. 6
It was confirmed that the feed amount could be properly secured and the crushing force doubled. In other words, pin conveyors of equal pitch do not give a shock to the processed material, so they have poor crushing power,
In addition, since the water is spilled smoothly from the coarse grain, it can be estimated that the feed amount becomes excessively small.

Therefore, in the pin conveyor, the pins or the rods are made up of a set of six members including a first member to a sixth member.
The angle between the first member and the second member is 120 °,
The angle between the member and the third member is 120 °, the angle between the third and fourth members is 60 °, the angle between the fourth and fifth members is 120, and the fifth and sixth members are Is preferably set to 120 °.

FIG. 7 is a view taken in the direction of arrow 7 in FIG. 3, and FIG.
FIG. 9 is a sectional view taken along line 7, and as shown in FIG.
The sixth member 36 preferably has a rectangular cross section in order to secure rigidity during stirring. Furthermore, in order to obtain the effect of cutting the processed object, both edges are pointed blade portions 55 and 5.
5 is good.

In FIG. 7, the first member 31 to the sixth member 36 are structured such that the flanges 56, 56 are fastened with bolts 57, 57 so that they can be replaced periodically or at any time for wear due to wear. If this structure is adopted, the bolt 5
Large tension is easily applied to 7,57,
The bolts 57 may be loosened or cut.

Therefore, in the present invention, the first member 31 to the sixth member
The stirring blade 58 attached to the tip of the member 36 is attached to the rotating shaft 2.
It was made of a V-shaped cross-section member that became convex toward 2. The V-shaped section may be angled. When the rotating shaft 22 is turned clockwise,
Since the processed material passes through the slope as indicated by the arrow, the stirring reaction force is reduced. This makes it possible to avoid damage to the stirring blade 58, damage to the bolts 57, 57, and breakage of the members 31 to 36 themselves.

However, since the processed material slips through the slope as shown by the arrow, the stirring performance is reduced. Then, a structure was devised in which the slope was depressed in an arc shape so that the stirring reaction force became small at the beginning of the slope and the stirring reaction force became large at the end of the slope, and good results were obtained when the structure was implemented. That is, the V-shaped cross-section member is composed of two arc-shaped cross-section members 59, 59.
Thus, good results could be obtained by constructing the shape of a person.

The conveyor according to claim 1 can be applied to a batch processing facility having only one tank in addition to a continuous processing facility.

Although the pin conveyor of the present invention is suitable for a garbage composting apparatus, it can be applied to other agitation apparatuses, ordinary composting apparatuses, and other industrial machines.
