Definitions
- the invention relates to a device for briquetting waste material according to the preamble of claim 1.
- Such devices are known from DE-A1 -33 33766 and EP-B1 -0 367 859. These are devices in which the waste material, which is often extremely loose, is fed into the briquette press by means of a special feeder device, namely in the press pre-stage in the form of a pre-compression chamber. This room is usually located above the actual press room. After filling the space of the press prepress, the waste material is compressed using a hydraulically operated pre-compression piston that performs a straight forward and backward movement. The waste material is compressed with the pressure of a pusher attached to the pre-compression piston. Under the action of this pusher, the waste material is compressed or pre-pressed and at the same time pressed into the actual press room, namely into the press chamber.
- the pre-presser During the actual pressing process, the pre-presser remains in its lower dead position and thus forms one of the press chamber walls.
- a main plunger which is usually mounted perpendicular to the pre-compression plunger, just as it is hydraulically driven and thereby performs a straight forward and backward movement, compact briquettes of stable shape are pressed out of the pre-pressed waste material as the end product.
- the finished briquettes especially those made from an elastic and non-conforming waste material, for example from metal chips, tend to expand again after being pressed together. Therefore, a device can be connected to the briquette press, in the chambers of which the finished briquettes are pushed in immediately after completion and remain there for a certain time before they are stacked or packaged.
- the chambers limit the tendency to change shape.
- the actual briquette press and this additional device work practically trouble-free, and their maintenance is very easy.
- the productive operation of the device depends to a considerable extent on the feeder device.
- the waste material to be processed is usually fed to the briquette press in such a way that the containers filled with it are tipped from above into a loading hopper.
- a loading hopper In the bottom part of the loading funnel there is a filling screw ke that conveys the waste material to where it is pressed.
- the waste material ⁇ without clogging of the hopper and without overloading the screw feeder and thus undisturbed falls into the feed screw, narrows the lower portion of the hopper in the direction of the filling screw which is arranged in the vicinity of the bottom of the hopper.
- this narrowed part of the loading funnel reduces the volume of the loading funnel, so that the overall height of this loading funnel must be chosen to be relatively large.
- the Container be tilted from above into the hopper and therefore have to be lifted over it to ⁇ . The relatively large height is therefore a serious disadvantage.
- an agitator is incorporated in the feed hopper.
- the short ones fall into the screw and are conveyed to the briquette press undisturbed.
- the long metal chips remain in one place. Further lien in the processing of long-fiber waste material ⁇ , which just chips from the metal works are to be expected that this skein form, the both adhered to each other, remain as even hanging on the lowest edges and protrusions and do not reach the hopper bottom or wrap around the agitator.
- Such metal chips do not break, but rather tend to wind up on the agitator and on the filling screw, which in turn gradually reduces the amount of waste material fed to the briquetting press and the installed capacity of the briquetting press can no longer be fully used.
- the device, including the briquette press, must therefore be switched off, and the wound up metal chips must be removed from all turned parts, in particular from the filling screw and the agitator, with great effort.
- the object of the invention is therefore to provide a device for briquetting waste material according to the preamble of claim 1, the device of which has a low overall height and works undisturbed without the need for vigorous manual intervention.
- the inventive device eliminates the need of a preceding comminution of the waste material prior to its introduction into the A ⁇ direction and the need for an agitator prior to introduction of the waste material in the briquetting press.
- a waste material consisting of various materials, including long and thin metal chips, is fed to the briquette press without any problems.
- the feed cutting ken and / or the auger on the tank only on one side. This enables unrestricted conveyance of the waste material.
- a pressure roller is arranged above the filling screw. This pressure roller prevents long metal chips from being wound up.
- the pressure roller is provided with pressure elements on its circumference. This pushes the waste material particularly deep into the auger.
- a further embodiment of the invention provides that the device is a tipper for raising and emptying is assigned a Kontainers and that the container ⁇ front wall of the means for engaging the Kontainers has a smaller height than the remaining receptacle walls. Thereby reducing REQUIRED ⁇ chen "height for the device is possible.
- the feeder screws are each provided with an independent drive which can be operated in both directions of rotation. Therefore, the distribution of the waste material in the device can be controlled and the blockage of the device can be counteracted.
- the pressure roller is next to its own drive for the screw feeder provided with a roller drive, and the Gearschneckenantrieb and the roll drive in both directions of rotation ⁇ be drivable. This can also counteract the winding up of waste material.
- a filling level monitoring is provided in the upper area of the device.
- the device can be attached to the briquette press as an independent module. The device can therefore easily be exchanged for another type of waste, depending on the type of waste material.
- the invention further relates to a device according to the preamble of claim 1, in which the briquette press has a molding chamber in which a press ram can be moved and which has a feed opening for the entry of the pressed material expelled from an opening of the container, and a slide valve device for closing and Has opening the mold chamber end.
- Such a device is known from EP-B1-0 748 276.
- the screw conveyor conveys the material to be pressed directly into the molding chamber via the container opening and the feed opening.
- This device is particularly intended for the briquetting of old and waste paper.
- the material to be pressed has adhering emulsions, oil components or air, as is the case with some dusts from exhaust air purification systems from various production processes or with metal grinding sludges, briquetting is difficult because of the moisture contained in the material to be pressed.
- the device according to the invention is intended to facilitate the briquetting of press material with moisture.
- the moisture can now be separated from the rest Press material to be separated and flow away, so that largely dry, pressed material reaches the molding chamber, in which it can then be compacted better.
- the separated damp substances can be collected and disposed of or reused in the processing machines.
- the screen opening is formed in the form of slots running in the longitudinal direction of the tube or at an angle. Therefore, the pressed material has enough time to drain during the conveying process.
- the tube consists of two nested, mutually adjustable tube parts for changing the size of the effective sieve openings.
- the screen openings in the tube parts can have different slot sizes with the same pitch.
- a further embodiment of the invention provides that the container with screw conveyor and worm drive is arranged such that it can be displaced and locked in relation to the molding chamber in the longitudinal direction of the screw and that the tube is fastened to the container in an easily replaceable manner. If the path for separating the damp substances from the pressed material is too short for some types of Pfessgut, then a longer tube can be used between the container opening and the feed opening, for example, which allows the dampened substances to drip off for a longer time.

- a device 3 of containers 1 is provided, and the device is equipped with a known briquette press 7 working with pre-presses.
- the device 3 comprises a container, which consists of a bottom 36, two side walls 31, 32, a front wall 33 on the side of a tipper 2 and an opposite rear wall 34.
- the device 3 can be attached to a briquette press 7 as an independent module.
- the tipper 2 is located in front of the device 3, serves to receive the container 1 filled with the waste material to be briquetted and to lift and empty it into the device 3, which is designed for this purpose.
- the side walls 31, 32 and the rear wall 34 are approximately the same height; however, the front wall 33 is kept significantly lower at the point at which the container 1 is emptied. At the upper edges of the side walls 31, 32 or at other locations in the vicinity of these upper edges, one or more light barriers 35 can be attached to prevent overfilling.
- On the lower front wall 33 three independent drives 41 for three feeder screws 4 are fastened, which are mounted horizontally and parallel to one another above the floor 36 and are only supported on the front wall 33.
- a filling screw 5 is arranged perpendicular to the longitudinal direction of the feeder screws 4 and at the same height as these, which is also attached above the bottom 36, provided with its own drive 51 and is only supported on the side wall 31.
- a pressure roller 6 arranged in parallel therewith, which is also provided with its own drive 62 and pressure members 61.
- the pressure members 61 are sheet metal strips which are welded to the surface of the pressure roller and which run in the longitudinal direction, at equal distances from one another and parallel to one another.
- the pressure roller 6 is arranged such that it moves away from the Filling auger 5 can move away. This can be achieved, for example, by a resilient mounting of the pressure roller 6, not shown.
- the free end of the filling screw 5 opposite the drive 51 opens into a pre-pressing chamber of the briquette press 7 already mentioned but not described further.
- feeder and filling screws with their drives for. B. as chip conveyor on lathes or milling machines.
- two feed screws 42, 43 closely arranged in parallel in a container 37 are at a right angle to the filling screw 5, which is driven by the drive 51 and is connected to the briquette press 7.
- the two feed screws 42, 43 are provided with their own drives 41.
- FIG. 7 which is similar to FIG. 6, the feed screws 42, 43 arranged in parallel in a container 38 are far apart in comparison to FIG. 6.
- feeder screws 42, 44 are at right angles one behind the other, while a filling screw 53 is arranged at right angles to the feeder screw 44.
- Feeder screws 42, 44 and filling screws 53 are accommodated in a container 39.
- the container 1 filled with the waste material for example with metal chips
- the tipper 2 which is started up in the usual way, for example with the aid of a pressure switch, and during the tilting movement
- Container 1 completely emptied into the facility 3.
- a scatter of metal chips to the outside via the lower front wall 33, thereby preventing the container 1 from blocking the pouring opening left free from the front wall 33.
- the empty device 3 can be filled with the waste material from more than one container 1 before the rotating parts of the device 3 begin to rotate.
- the light barrier 35 monitors the filling level of the device 3.
- the rotating parts namely the feeder screws 4 and the filling screw 5, are put into operation upon a signal from the light barrier 35.
- the feeder screws 4 convey the metal chips in the direction of the filling screw 5, which takes over the metal chips and guides them to the briquetting press 7 with a change of direction.
- the metal chips processed in the briquette press need not be crushed before being introduced into the device 3.
- the device according to the invention also does not require an agitator for mixing the various types of metal chips, which might have to be used because of a trouble-free conveyance of the metal chips.
- the device is therefore able to process chips of different thicknesses and lengths, metal chips, etc. without any preprocessing.
- the pressure roller 6 with its own roller drive 62 ensures that no long chips are wound onto the filling screw 5 and this can no longer fulfill its function.
- the function of the pressure roller 6 and in particular of the pressure elements 61 is to press the waste material into the free locations of the screw of the filling screws 5 and also to prevent it from moving other than in its axial direction.
- the metal chips to be processed cannot fall out because the receiving space for the filling screw 5 has a corner which is formed from the bottom 36 and the rear wall 34.
- the drives 41 of the feeder screws 4 and the drive 51 of the filling screw 5 are in both directions directions operable. These drives can therefore be set in such a way that the feed screws 4 and the filling screw 5 first move in the forward direction of rotation for a certain time and then in the reverse direction of rotation for a few revolutions. It has been shown that the metal chips wound on the screws during the forward rotation direction are released by this movement in the reverse rotation direction. If the screws then move in the forward direction of rotation, the released metal chips are taken in the desired direction. The same also applies to the pressure roller 6 and its roller drive 61, the pressure roller 6 not necessarily having to rotate in the same direction as the filling screw 5.
- the metal chips are thus reliably conveyed in the direction of the pre-pressing chamber of the briquetting press 7, in which the actual briquetting takes place.
- the finished briquettes come out of the briquette press 7 through the briquette outlet 71, but after-treatment devices can also be connected to the briquette outlet 71, which serve to ensure that the briquettes retain their shape better.
- the feed screws 4, the filling screw 5 and the pressure roller 6 are equipped with separate drives. These separate drives make it possible that, in the event that there is an uneven distribution of the metal chips on the bottom 36 of the device 3, one feed screw is operated, but another feed screw can be shut down.
- Dependency of the running of the turned parts on the resistance of the waste material to be processed etc. are controlled by programming units, which are generally known and are not the subject of the invention. However, these programming units can also have different programs with special or very different properties.
- the speeds of the individual turned parts can be changed, for example by means of a frequency converter, such that, for example, the individual feed screws 4 are operated at different speeds.
- the waste material also does not need to be introduced in the manner described, ie with container 1 and tipper 2. Rather, the waste material to be processed can also be introduced, for example, with an assembly line.
- the start of the rotating parts can also be controlled by means of the light barrier 35, depending on how high the device 3 is filled.
- the device shown in FIGS. 9 and 10 has a feed container 3 in the form of a funnel for filling in pressed material, which opens into a trough 102.

- the piston 1 15 is driven pneumatically or hydraulically.
- the device also has a displacement transducer 11, which is attached to the cylinder-piston unit 108.
- a displacement transducer preferably as an ultrasound or laser range finder, can also be used outside the cylinder-piston unit 108.
- a variable pressing process is possible with this displacement sensor.
- the speed of the press ram is variable in the forward direction and can therefore be adapted to an optimal press result. This variable speed can be achieved, for example, preferably with controllable pumps at constant speed or with constant pumps with preferably frequency-controlled drive motors.
- the device can also work in such a way that a failure to reach the predetermined final pressure position of the press die 110 is detected by the displacement sensor 11, which then causes the press operation to be repeated with the press die 110.
