Description

"Device for the processing of residual concrete"

The invention relates to the configuration of a device to remove residual concrete to be dismantled in the form of back-concrete and wash-out concrete with a proportion of material that can still be set into individual reusable fractions.

It is not limited to suspensions with substances that can be set but can also be used in the same way for the processing of waste materials in the Exposed aggregate concrete industry (partially tied) or in sawing and grinding operations for stone processing (fully tied) are used.

This patent application DOS 26 51 937 describes a solution to residual concrete and back concrete, as it occurs in ready-mixed concrete plants, in precast concrete plants, To be dismantled before setting into a cleaned and washed, reusable one Grain fraction and into a liquid phase, consisting of water, cement paste and dust particles. The liquid phase can also be reused. For this purpose is a Sludge pump is provided, which is in a dewatering device above the compulsory mixer promotes. The facility is also used in other branches of the mineral industry can be used for fractional recovery.

According to Fig. 1, 2 and 5, the vibration washing system is pre-assembled Unit designed that is built so high that it can still be carried on a truck or low-bed trailer is transportable, i.e. the feed plate with vibrating sieve and sludge collecting tank including pump and cyclone or, according to FIG. 5, these Components together with a loading buffer container form 1 preassembled as a structural unit transportable device.

A solution according to DAS 26 03 093 is known. An attempt is made here Coarse parts over 1 sieve, fines over single 2. Sieve below at right angles to separate. Fines go through the fine sieve.

The disadvantage of this solution is that once the residual In particular, back concrete can never be added so evenly that an even, clean washing is possible, on the other hand, that the fine sieve wears out too quickly and quickly clogged by cement paste.

DAS 19 14 147 also describes a device for separating of liquid and solid substances.

This solution cannot be used for back concrete, once, because also there is no buffering with dosed sieving, on the other hand there can be cyclone underflow are not abandoned at the beginning of a conveyor screen. On the long conveyor route would too large a proportion of fines has been flushed through and constantly in circulation. In the end this device is based on separation only small bandwidth of the grain size, so about 0 - 4 mm designed, not 0 - 32 mm. The main area of application of this device is when washing sand, i.e. separating out mineral impurities and Drainage of ores or sludge.

In the course of development it has now been found that the structure the washing device according to PA 26 51 937 is in principle correct, but still to be improved is to give this system sufficient operational safety and optimal operation respectively.

The following points also have a disadvantageous effect: 1. that with the linear sieve solution the sludge collecting tank with a vertical outlet opening and limited overall height not to keep the corner angles of the sludge collecting container free was. Cement paste with fine sand constantly settled - even with slip angles over 500 - until finally the pump blocked.

2. That the too deep-lying cyclone is a transfer of the sludge If a discharge line is inclined sufficiently, this is impossible over long distances made.

3. that the ejection of the concrete / water mixture from the transport mixer on the slightly inclined cover plate to excessive contamination of the entire system caused by ricochet splash.

4. that the return of the components i 0.06 / 0.15 mm on the vibrating sieve for removal with the coarse parts outside of the sludge collection container and too much entrained water was carried out with the solids.

5. that the vibrating screen is rigidly inclined towards the discharge side and Was not adaptable to different performance ranges and items to be washed.

These disadvantages have been overcome by an embodiment according to the invention completely switched off.

In addition, through further measures, the Device indispensable maintenance costs are kept to a minimum, i.e. the The degree of self-cleaning has been greatly improved.

About the total height of 2.75 m and a certain throughput to be able to maintain, so to get the pre-assembled construction, even with one Task buffering from 2 - 2.5 m9, it was necessary to construct a number of difficult individual problems to solve, namely: 1. A task buffer system with large Surface, low overall height and large capacity (approx. 2 - 2.5 mi water value) with an adjustable dosing device on the vibrating sieve.

2. An extremely flat vibrating screen with high torsional stiffness and sufficient self-cleaning effect.

3. A favorable combination of a sludge collection tank with a sludge removal pump, Easily accessible, easily removable with automatic self-rinsing of the sludge collection container.

4. A protection system that prevents cement paste once Water escapes from a room above the vibrating sieve and the entire device so dirty that the function is in question. This shoe should be flexible and can be removed quickly so that controls can be carried out easily.

on the other hand, a splash guard must be used in conjunction with the loading buffer tank be adaptable to different locations.

In one embodiment of the inventive concept, the aforementioned Construction unit combined with a water refill boom, which enables the required Rinse water in the approx. 3.5 to 3.8 m high inlet funnel of the transport concrete mixer admit. This water refill gallows is also a carrier according to the invention of the cyclone, the fine material discharge of which is so high that an above-floor container from a height of approx. 2 m via a sloping drain can still be charged within a radius of up to approx. 10 m is.

It should be emphasized once again that the active one is capable of being set Cement paste that is to be separated from the concrete mass with this device, in all housings, pipelines. sets down on flat and inclined surfaces, hardened to cement stone and the entire device within hours and days can render useless.

Therefore, certain parts of the device cannot be considered in isolation but these must be understood as being included in the process flow.

Experience has shown that it makes sense to use the ready-mix concrete mixer to refuel with flushing water at the emptying point, i.e.

No change of location should be planned between refueling and emptying. That but it is only possible if the emptying takes about 300 liters of water + 100 1 solids (average value) in a buffer container within seconds can be done. Even when returning concrete, a large-volume buffer is created, which is easy to keep clean and which promotes the mass evenly, positive noticeable.

It is appropriate for manufacturing and assembly reasons, the water refill gallows to connect with the device and this not about on the ground next to the To set up the system.

There is a walk-on grate over the for emptying concrete pumps Feed buffer container is essential because the staff is working on the pump slide system does the main cleaning work and this slide system directly above the feed buffer container should stand.

Since the locations are different in every company, it is important to to the location of the discharge elements such as conveyor belt or bucket elevator for the solids to find a very variable position of the water refill lines and the splash guard.

It must nevertheless be possible with the transport mixers in the through-sieve axis or any number from 0 to approx. 900 on both sides.

The outlet pipes of the water refill device must accordingly be adjustable about a vertical axis.

In addition, it turned out to be cheap, the rinse water to be supplied via one or the other column of the water refill gallows. It must only ensure that the pipe system for winter operation is automatic emptied.

When adding rinse water, it must be taken into account that it is used for washing-out purposes approximately the same amount is poured into each transport mixer.

In order to save several separate lines and pumps, it has been done proved to be expedient that the filling of the pipe system by 1 pump and the Distribution via valve-controlled outlets is favorable.

Experience has shown that the loading buffer container should have a (capacity of 2 - 2.5 m 'of solid liquid. The surface should be as large as possible and therefore became a flat, cylindrical container with a flat bottom viewed as optimal, especially taking into account the overall height of the overall device from 2.5 - 2.75 m.

The functional requirements are that such a container is completely emptied and kept clean on all surfaces without maintenance.

Manual maintenance would only involve lifting off the heavy walk-on grate possible. When the cavity of the inner cylinder is used to accommodate the drive is the problem of ventilation and the problem of cementitious water mist to solve.

The external drive is without problems in this context with cardan shaft connection to the central bevel reduction gear.

It has been shown that it makes sense to put the one on the sieve To make solid sludge amount controllable.

If, for example, a large amount of hardened concrete is poured into the feed hopper with little water poured, then the flow openings must be enlarged because the Prevent solids from passing through the openings.

But it only becomes more washed-out concrete, i.e. a small amount of solids with a large amount of water added, then the amount of water washes the solids through relatively small openings through quickly and without resistance and the slide opening will be kept smaller.

It is useful to adjust the slide by means of a servomotor or a hand crank from a point above the input buffer container.

When it comes to the design of the vibrating sheave, it is flawless Cleaning of the coarse aggregate from 3 - 4 mm in 1 pass with the shortest possible total length of the sieve, namely a quantity of 10 - 25 t / h as well as a safe clearance of the screen lining without maintenance and additional equipment - such as brushes or knockers - and a safe one Drainage of all solids including those coming from the cyclone underflow lowest possible passage that has to be processed by the sludge pump and cyclone, to meet. It must be taken into account that the solids content in cyclone separation is limited, i.e. with a proportion of 25 solid%, a water quantity of about 35 - 45 m '/ h in circulation. Elevated the resulting amount of solids by using coarser sieves, the total circulation volume and the pump drive power also increase and the cyclone size.

Tests have shown that a plastic screen of the latest development with the existing operating conditions 2.5 - 3 mm> must have passage in order to be free to stay. If you get into the lower size range, you also need a quick water drain be switched on. It is important that the cement paste is properly separated before the solids fall off the sieve, because the solids would be about Block a bucket elevator, or bake it together in such a way that reuse is eliminated were.

In this context it is important to use the sieve surface evenly high pressure and for nozzle cleaning the spray system in a few simple steps to be able to take out.

Water / cement paste / fine sand run off through the sieve and are in the Sludge collection container collected. The sinking movement is reduced by filling it with water also of the largest parts, so that the components are also on an inclined surface deposit (lamella separator principle!).

The installation of agitators, scrapers, vibrators is prohibited Price rises in such systems.

With the arrangement of spray nozzles according to the invention, a level control device this difficult problem can be solved in conjunction with pump tuning.

Without a 100% joint mastery of container emptying by a robust, maintenance-free fines or sludge pump is not the operational reliability guaranteed. So it is important to install the right device here so that it Can be dismantled and reassembled at the moment.

With regard to frost protection, all water-bearing systems are to make it automatically drainable. Because of the possibly high volume of dirty water at improper water clarification are special on the line routing and the locking devices To make demands.

Finally, it has proven to be advantageous to use the water filling gallows, the spray system of the feed buffer tank, the sieve spray system and the cyclone underflow line as well as the refilling and spraying system in the sludge collecting tank of one water pump each from operate. It is thus avoided that withdrawals are superimposed the pressure ratios and quantity ratios important at all points change for a short time change.

Without a program control, there is the required functional reliability not guaranteed. The solution according to the invention in particular with regard to the Self-cleaning ensures trouble-free operation over a long period of time.

Further functionally important relationships and technical details are provided explained in the following description of an exemplary embodiment.

1, 2 and 3 deal with the overall device.

The tool carrier 14 carries several oscillating around a horizontal axis Support arms 15 with feeder blades 16.

An outlet slide device 17 enables uniform metering the mass to be processed on the vibrating sieve 2. On the upper water-bearing Pipe reinforcement ring 12 is located on a grate 18 that can be walked on. The inner surface of the outer jacket is cleaned by spray nozzles.

A loading buffer container 1 with internal drive according to Fig. 4 is cheaper, but requires a supply of cooling air. The bottom 10 must remain closed because the cement-containing water mist would concretize the entire drive.

In the case of a drive according to FIG. 5, there is a flat construction at the bottom of the container Bevel gear 20 is arranged and the connection from the gear motor 13 is via PTO shaft 21. Here the drive is easily accessible and easy to protect.

The F i.g. 6, 7, 8 show details of a vibrating screen according to the invention 2. With 25 the outwardly open U-shaped cheeks are marked, which at the ends are held at a distance by transverse plates 26, while in the middle area Hollow profiles 27 ensure high torsional and torsional rigidity. The outer cheeks are closed on the outside in the middle area and form the Edition 28 of the two vibrators 29. Within the cheek there are sieve mats 30 and drainage sieve mats 31, are clamped with wedges and by longitudinal hold-down profile strips 32 held down vibration-proof. The spring brackets 33 with springs 34 are supported in height-adjustable bearing parts 35 on the support frame 8. The adjustability in the height takes place, for example, via a round thread in the bearing part 35, which the fixed bearing block 37 engages over.

In the middle sieve field, a baffle 38 is vibration-proof and adjustable in height stored or fastened in the side walls. The inclination or

The height of the baffle is the expected maximum throughput customized. It prevents the bulk of the material from getting too clean too quickly and too little is promoted. The rotating movement of the grains in front of the accumulation bar also the cleaning effect is improved.

The entire screen surface is through at least 2 spray tubes 39 with cone jet nozzles 40 and pressurized water of 1 4 bar sprayed. To achieve quick cleaning of the nozzles, the pipes are inserted into a holder 41 at the rear end and at the front with a Bayonet bracket 42 attached.

The hose connection 43 takes place via quick coupling 44 with 3 is in Fig. 9, 10 the sludge collecting tank, each consisting of 2 symmetrical longitudinal walls 48 and transverse walls 49 with upper stiffening tubes 50 and the mounting brackets 51 , designated.

A longitudinal wall 48 is drawn out in the center and here is the mud pump 52 used in a wear-resistant, dry-run safe, stuffing box-free design and can be plugged and screwed onto the upper mounting plate 53. Alternatively, it can be used in be held in the lower area by a plug-in device. The pump just sucks above the lowest point of the container. The intake manifold runs essentially perpendicular to prevent deposits in this area.

This pump 52 is quickly on the side of the vibrating sieve in the event of a repair 2 and infeed buffer container 1, remove and install past.

The feed line 54 to the 4 corner spray nozzles is located inside the container 55. The pipe cross-sections are matched to the distribution quantities.

The float switch 56 switches a feed pump 57 when it is reached the minimum water level on and off when the maximum water level is reached.

After the feed rate is greater than the discharge rate, lift and the water level drops periodically and each time it reaches the lowest The container corners are flushed free under pressure.

If the water level - rising - has reached the nozzle outlet cross-section, the jet effect of the spray nozzles is reduced.

The support frame 8 carries according to FIG. 11 the water refill gallows 60 at the top at least 2 outlet pipes 62 lockable with engine valve 61 by at least 1500 are arranged pivotable about a vertical axis outlet pipes. These Outlet pipes are set to the most favorable location for the transport mixer.

The cyclone 63 is also suspended from the water refill boom. At 64 is the supply line from the sludge pump 52, with 65 the overflow of the fines, with 66 the cyclone underflow of the fines on the vibrating sib 2 is marked.

In Fig. 12 is an embodiment for the self-cleaning of the Inner wall 11 of the container is shown.

A square tube forms the reinforcement on the upper edge of the container 12 and is at the same time water conduction. There are numerous nipples 70 on this pipe with raw arch 71 and flat steel spray nozzles 72 arranged so that the wall surface to almost 100% is sprayed.

The accessible grating 73 rests on the water guide pipe 12 likewise the cover plates 74 resting on the outside, while the lower edge 75 of the spray protection 5 is fastened to the container wall 11 in a screwable manner. Please refer F i g. 13th

The F i g. 14 shows the connection of the spray line 39/40 over the Sieve, the spray line 12 in the feed buffer container 2 and in the cyclone underflow 66. By means of slide 78, the amounts of water are in the feed buffer container and in the Adjustable cyclone underflow.

All lines up to pump 79 have a gradient for safe emptying executed.

Normally, the spray protection device 5 according to FIG. 15 symmetrical arranged to the supports of the water refill boom 60. Depending on the location Depending on the need, it can be moved up to 900 to the left or right the center position may be required.

Corresponding holes 81 are provided in the container jacket 11 for this purpose intended. In such an application, sealing plugs 82 must be in openings the bulkhead are removed so that water over the end plate 74 through the The bulkhead is passed through into the container 1, see also FIG. 13.

The grate cover 73 over the loading buffer container 1 as a flat iron grate executed, can be 1-part! or 2-part and it is made of wear-resistant and self-cleaning reasons can be rotated as required, FIG. 16.

A flat slide solution on the bottom 10 of the feed buffer container in linear execution is shown in FIG. 15 in the print view. The openings in the floor panel 10 are guided through the slide plate 85 by guide lugs 86, or more less covered. The longitudinal displacement can be carried out via an abutment 87 via a spindle 88 and handwheel or motor drive 89 take place.

With this arrangement of the passage opening in a tendon, a relatively small area of the feeder tools more heavily loaded, i.e. it locally higher wear occurs.

An embodiment according to FIG. 1 avoids this disadvantage. 16 Here is a segment slide plate 90 mounted at 0, passed through lugs 91 and is over Spindle 88 and abutment 87 adjusted by means of a handwheel or electric motor 89.

In an embodiment not shown further, it is provided in the case of "washing out" a certain smaller one, in the case of "reclaimed concrete" a larger one The opening width can be approached by motorized adjustment using the limit switch.

It has a positive effect on the self-cleaning effect of the entire system the semi-automatic sequence according to FIG. 17 off, in particular a follow-up control is here provided in such a way that, from a switch-off point, the subsystems have timers a), b), c) switch off in a controlled manner.

The automatic delay d) is provided to avoid inrush current peaks to reduce.

So "fill up with water" and "start washing system" take place manually, all other functions automatically.

An embodiment of the adjustable stowage bar in the middle Sieve area is shown in FIG. 18 shown. The flat iron 92 with bolt 93 is in the longitudinal hold-down profiles 32 and the outer cheeks 25 supported and with Adjusting lever 94 and screws 95 it is held in the set position. One The damming effect at the end of the vibrating sieve is achieved, for example, by using a transfer device 96 with side cheeks 97 screwed on the front side on the cross plate 26 of the sieve frame and is designed to be height-adjustable in elongated holes.

F i g. 19 makes it clear how the space is used in an exemplary embodiment between the bottom 10 of the loading buffer container 1 and the screen cheeks 25 by elastic Rubber apron once across the rear 98 and front 99 as well as lengthways 100 and on both sides the top surface 101 of the longitudinal parts 100 is completed as an extension of the container bottom 10 will. Only a strip of approx. 20 cm at the end of the vibrating sieve is not covered, to be able to observe the degree of cleaning.

The lower end of the cyclone underflow pipe has proven to be useful 66 according to FIG. 20 finger-like 102, i.e. the material flow is pulled apart and falls in about 4 partial streams at an even distance onto the sieve.

The more evenly and thinner this flow of material reaches the sieve, the more completely it can be freed from the cement paste on the remaining flow path.

According to the invention, the material flow in the first third should reach the dewatering screen section 31 hit.

The F i g. 21/22 represents a variant of a possible loading buffer container It consists of a funnel-shaped sheet metal part 105 with 1 to 4 waterproof suspended vibrating channels 106 and adjustable stowage bar 107. The Transport take over the vibrators, the quantity delivery the variable stowage bar that also motorized for washout "or" back concrete "can be set.

The transport mixers 9 push backwards in front of the washing system, refuel a certain amount of water, rinse the drum and give the residual concrete or the Reclaimed concrete via the emptying chute into the buffer hopper 1 to get it there already pre-wash. Via the metering slide 17, the items to be washed are transferred to the vibrating sieve 2 assigned.

A proportion of 0 - 2.5 / 4 mm of approx. 28 - 42% of the total continuous The amount of solid runs through the sieve 30 and is separated in the cyclone 63 into 0-0.06 / 0.15 and 0.06 / 0.15 to 2.5 / 4 mm.

The fine materials 0 - 0.06 / 0.15 mm are either in containers for Brought to settling or fed into agitator tank, prevented from setting there, to be reprocessed.

The vibrating sieve 2 is placed on a conveyor belt 8 or via an inlet funnel into a bucket elevator, which set up the solids in a silo, a container or Anhägner promotes.

The entire system can be set up so that the grate is flush with the floor or protrudes by a distance of up to approx. 1.2 m above the floor. The latter list is interesting when the pit depth has to remain limited, for example because of groundwater.

A concrete pump emptying always requires a floor-level installation.
