Device for compacting waste.

The invention relates to a device for compacting Waste.

It is known to put bulky garbage or trash in cylindrical Compress containers by means of a piston. Usually there is a paper bag or the like below the cylinder, and after compacting the waste, it becomes automatic led into the bag. However, such devices have a relatively low capacity because of the movements of the piston in the forward and backward directions for each pressing operation claim a relatively long time. In addition, the waste often contains liquids that are compacted with the Mix the mass so that it becomes heavy and the liquid leaks through the paper bag.

The task of the invention is to create a compacting device to create, which is suitable for restaurants, bars, canteens, hospitals, etc., in which often in faster Sequence waste items need to be compressed that like E.g. half-empty pouches for potion fluids, quite a lot Contain liquid.

Above; The object is achieved according to the invention by a compacting device, marked by

a pre-pressing device, consisting of at least two conveyor tracks converging in the conveying direction, between which the waste can be imported,

a pressing device, consisting of two interacting, spring-loaded, rotating rollers, - their intermediate gap essentially at the apex of the converging Conveyor tracks is located,

a liquid storage tank below the conveyor tracks and rollers and

a waste collection container, the inlet opening of which is attached adjoins the exit side "of the intermediate gap between the rollers.

The entire device is expediently in a housing installed which has an opening with a feeding device such as a hopper or a chute.

The invention is explained in more detail below with reference to the drawing.

The illustrated Konpaktierungsvorrichtung has a pair of interacting 'valzen 1o, 11, each of which is mounted on two pins 12 and 13, respectively. The roller 11 is pressed against the roller Io by means of strong springs 14. The pins 13 are rotatably seated in a sliding block 15, which slides in a vertical link 17 of a fixed bearing housing 16, being pressed downwards together with the roller 11 by the action of the springs 14. The spring pressure can be adjusted by means of an adjusting device (not shown) and adapted to the type of waste objects to be compressed. The pins 12 are received in a conventional manner in fixed bearings, one pin

a pulley, a sprocket 18 or the like. wears which can be driven together with the roller by a motor 19, a transmission 2ο and a transmission. It is, of course also the possibility of driving both rollers and loading them with springs if this is deemed necessary.

A conveyor belt 22 or 23 runs over each roller, which on the other end is guided over guide rollers 24, 25. The axes of rotation of the deflection rolls and the press rolls are parallel. the lower deflection roller 24 is arranged with respect to the roller to so that the upper belt of the conveyor belt 22 runs essentially in a horizontal plane. The distance between the upper deflection _ roller 25 of the lower deflection roller 24 is chosen so large that the two conveyor belts narrow in the conveying direction Limit the conveying channel 26 leading to the rollers 1o, 11 leads. In this arrangement, the conveyor belts form a conveying and pre-pressing device for the waste.

The conveyor belts 22, 23 can for example be made of stainless steel or rubberized fabric. At least the lower conveyor belt should be provided with perforations 27 through the liquid can drain. Un to take away the rubbish To improve the conveyor belts, teeth or knobs can be provided on the surface of the belts.

A collecting container is located under the conveyor belts 22, 23 28 for /. Waste liquid, which is directly or through a filter can be discharged through a drain. In the upper area of the collecting container 28 is a sensor 29 for displaying the highest liquid level installed, the signal of which is displayed by a warning lamp 3o when the collecting tank is full ict and must be emptied.

Tietallic baffles are located near the end of the conveyor belts attached, which the liquid draining from the conveyor belts pass into the collecting container 28. In addition, a key

Sheet 33 attached in front of the insertion opening of the device, which ZUTn the lower conveyor belt 22 is inclined and this the Abfallqegonständ.e feeds. The space to the right below the rollers 1o, is a waste airynel container in the form of a paper or Plastic bag 34 taken, which with its opening on a Ring 35 is stretched, which is the end of a bag leading channel 36 is. The bag rests on a carriage 37 which can be driven out for emptying.

The device is also equipped with a spray device 38, which is connected to a water or steam connection via a valve 39 and a line 4o. In the example the spray device is composed of pipes arranged in a V-shape with nozzle openings 41, which are located on both sides the conveyor belts are misplaced. Hot water or steam can be sprayed onto the conveyor belts through the nozzles.

The device described above works as follows:

Waste, often in the form of half-empty beverage packs made of plastic or paper, glass bottles, etc., is deposited on the guide plate 33 and from there via the conveyor belt 22 to the rollers 10, 11 The two converging conveyor belts are increasingly compressed, and the outflowing liquid flows through the perforations 27 of the conveyor belt into the collecting container 28. The waste is then pushed _{through between the rollers 1o 7} 11 and falls behind them in the form of flat pieces and splinters into the waste air container 34.

The device can be cleaned easily after use are by means of the spray device 28 steam or hot water, if desired, mixed with detergents on the Conveyor belts being sprayed. This liquid is also collected in the container 28 and drained with the waste liquid.
