Definitions

  • the invention relates to a device for briquetting of waste material according to the preamble of claim 1.
  • Such a device is characterized by the US 5 017 124 A known.
  • the filling screw is only supported on one side of the container.
  • the disadvantage is that the waste material is only loosely supplied to the briquette press and thus the briquettes are insufficiently precompressed.
  • a device can be connected to the briquetting 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 restrict the tendency to change the shape.
  • the actual briquette press and this additional device works virtually trouble-free, and their maintenance is very simple.
  • the productive operation of the device depends to a considerable extent on the feeder device.
  • the waste material to be processed is usually supplied to the briquette press such that the containers filled with it are tilted from above into a feed hopper.
  • a feed hopper In the lowest part of the hopper is a Gresman's hopper, which promotes the waste material to where it is pressed. So that the waste material without blockage of the feed hopper and without overloading of the filling screw and thus undisturbed falls into the filling screw, the lower part of the hopper narrows in the direction of the filling screw, which is arranged in the vicinity of the bottom of the hopper.
  • an agitator is installed in the feed hopper.
  • the short ones fall into the screw and are conveyed undisturbed to the briquetting press.
  • the long metal chips remain in one place.
  • long-fiber waste materials which currently include shavings from the metalworking, are expected to form these clumps that adhere to each other, as well as get stuck on the smallest edges and protrusions and do not get to the hopper floor or to wrap the agitator.
  • Such metal chips do not break but rather tend to wind up on the stirrer and auger, again reducing the amount of waste fed to the briquette press and making it impossible to fully utilize the installed capacity of the briquette press.
  • the device including the briquetting press must therefore be switched off, and the wound metal chips must be removed from all rotating 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 of waste material according to the preamble of claim 1, the device undisturbed process any waste material including long, thin metal chips and thus can work without the need for a vigorous manual intervention.
  • the device according to the invention eliminates the need for a prior crushing of the waste material prior to its introduction into the device and the need for an agitator before introducing the waste material in the briquette press.
  • the supply of a variety of materials, including long and thin metal shavings, existing waste material to briquette press is trouble-free.
  • the pressure roller is provided at its periphery with Anpressgliedern. As a result, the waste material is pressed particularly deep into the filling screw.
  • a further embodiment of the invention provides that the device is associated with a tipper for lifting and emptying a container and that the container front wall of the device for engagement of the container has a lower height than the other container walls. This makes it possible to reduce the required height for the device.
  • the feeder augers are each provided with a separate drive which is operable in both directions of rotation. Therefore, the distribution of the waste material in the device can be controlled and counteracted clogging of the device.
  • the pressure roller in addition to the own drive for the filling screw, is provided with a roller drive, and the Fütlschnedcenanirieb and the roller drive are operable in both directions of rotation. This can also counteract a winding of waste material.
  • a filling level monitoring is provided in the upper region of the device.
  • the device can be attached as an independent module to the briquetting press. The device can therefore be easily replaced by another, even depending on the type of waste material against a different kind.
  • the invention further relates to a device according to the preamble of claim 1, wherein the briquette press a mold chamber in which a press die is movable and which has a feed opening for the entry of the expelled from an opening of the container pressed material, and a closure slide means for closing and Opening the mold chamber end has.
  • Such a device is from the EP-B1-0 748 276 known.
  • the screw conveyor conveys the material to be pressed via the container opening and the feed opening directly into the mold chamber.
  • This device is especially intended for briquetting waste and waste paper.
  • the material to be compacted has adhering emulsions, oil fractions or air, as is the case with some dusts of exhaust air treatment plants from various production processes or with metal abrasive slurries, briquetting is difficult because of the moistures contained in the material to be pressed.
  • the device according to the invention is intended to facilitate the briquetting of wetted with pressed material.
  • the sieve opening in the form of formed in the tube longitudinal direction or obliquely extending slots. Therefore, the material to be pressed during the conveying process for draining enough time.
  • the tube consists of two nested, mutually adjustable pipe parts to change the size of the effective screen openings.
  • the screen openings in the tube parts can have different slot sizes with the same pitch. By simply turning one of the two pipe parts, it is therefore possible to set the desired gap.
  • a particular advantage is that by setting the gap to maximum size, blockages can be easily eliminated.
  • a further embodiment of the invention provides that the container with screw conveyor and worm drive relative to the mold chamber in the screw longitudinal direction is arranged displaceable and lockable and that the tube is attached to the container easily replaceable. If the route for separating the moist substances from the pressed material is too short for some types of pressed material, then, for example, a longer tube can be inserted between the container opening and the feed opening, which allows the pressed material to drip off for a longer time.
  • 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 briquetting press 7 as an independent module.
  • the tipper 2 is located in front of the device 3, serves to receive the filled with the waste material to be briquetted container 1 and its lifting and emptying into the device 3, which is designed to suit.
  • the side walls 31, 32 and the rear wall 34 are about the same height; however, the front wall 33 is kept significantly lower at the point where the container 1 is emptied.
  • one or more light barriers 35 may be attached to prevent overfilling.
  • three independent drives 41 are attached to three feeder screws 4, which are mounted horizontally and parallel to each other above the floor 36 and mounted only on the front wall 33. Perpendicular to the longitudinal direction of the feeder screws 4 and at the same height with these a filling screw 5 is arranged, which is also mounted above the bottom 36, provided with its own drive 51 and is mounted only on the side wall 31. Notwithstanding this rectangular arrangement of feeder screws and filling screw they can also be arranged at a different angle to each other.
  • a pressure roller 6 arranged in parallel therewith, which is also provided with its own drive 62 and pressing members 61.
  • the pressing members 61 are metal strips which are welded to the surface of the pressure roller and extend in the longitudinal direction, at equal distances from each other and parallel to each other.
  • the pressure roller 6 is arranged such that in an emergency at standstill and during operation of the Fill screw 5 can move away. This can be achieved, for example, by a non-illustrated spring-back mounting of the pressure roller 6.
  • the drive 51 opposite, free end of the filling screw 5 opens in a pre-compression chamber of the already mentioned, but not further described briquetting press 7 a.
  • FIGS. 6 to 8 are further possible arrangements of feeder and auger shown with their drives, z. B. as chip-fitter on turning or milling machines.
  • Fig. 6 are two closely arranged in a container 37 parallel feed augers 42, 43 at a right angle to the filling screw 5, which is driven by the drive 51 and is connected to the briquetting press 7.
  • the two feeder screws 42, 43 are provided with their own drives 41.
  • Fig. 6 resembling Fig. 7 lie in a container 38 arranged parallel feeder screws 42, 43 in comparison to Fig. 6 far apart.
  • feeder screws 42, 44 are at right angles to each other, while a filling screw 53 is arranged at right angles to the feeder screw 44.
  • Feed screws 42, 44 and filling screws 53 are housed in a container 39.
  • the operation of the device according to the invention is the following:
  • the filled with the waste material, such as metal chips, container 1 is moved manually into the tipper 2, which is set in the usual way, for example by means of a pressure switch, in operation and during the tilting movement
  • Container 1 completely emptied into the device 3.
  • the empty device 3 may be filled with the waste material from more than one container 1 before the rotary parts of the device 3 start to rotate.
  • the light barrier 35 monitors the level of the device 3. In response to a signal from the light barrier 35, the rotary parts, namely the feeder screws 4 and the filling screw 5, are put into operation.
  • the feeder screws 4 convey the metal shavings in the direction of the filling screw 5, which takes over the metal shavings and directs them to the briquetting press 7 with a change of direction.
  • the processed in the briquetting metal chips do not need to be crushed before introduction into the device 3.
  • the device according to the invention also needs no agitator for mixing the various metal chips, which might have to be used because of a trouble-free transport of the metal chips.
  • the device is thus able to process chips of different thickness and length, Metallspanknäuel etc. without any pre-processing.
  • 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 their function.
  • the task of the pressure roller 6 and in particular of the pressing members 61 is to push the waste material into the free places of the screw of the filling screws 5 and also to prevent them from moving differently than in their axial direction.
  • the metal chips to be processed can not 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 metal chips are thus reliably transported in the direction of the pre-compression chamber of the briquetting press 7, in which the actual briquetting takes place.
  • the finished briquettes pass through the briquette exit 71 into the open, but it can be connected to the briquette 71 also aftertreatment devices, 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 allow that in the case where there is an uneven distribution of the metal chips on the bottom 36 of the device 3, which operates a feeder screw, but another feed screw can be stopped.
  • the setting of the independent gear of the individual feed screws 4, the mutual ratio of the speeds of the feed screws 4 in the forward rotation and reverse rotation, optionally the same speed ratio of the filling screw 5 and the pressure roller 6, the function of the photocell 35 for the start of the rotary parts, the dependency the running of the rotating parts from the resistance of the waste material to be processed, etc. are controlled by programming units, which are generally known and not the subject of the invention. However, these programming units can also have different programs with particular or strongly differing properties. Depending on the conditions within the device 3, for example by means of a frequency converter, the rotational speeds of the individual rotary parts can be changed such that, for example, the individual feeder screws 4 are operated at different speeds.
  • the waste material also does not need to be introduced in the manner described, that is to say with container 1 and tipper 2. Rather, the waste material to be processed, for example, be introduced with a conveyor belt. In this case, the start of the rotary parts can also be controlled by means of the photocell 35, depending on how high the device 3 is filled.
  • the device illustrated 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.
