"Method and device for processing loose waste"

The invention relates to a method and a device for treating loose waste. These can consist of a Household, a hospital or a commercial enterprise. The invention is essentially intended to be an improvement in the process of transporting these masses to a processing center.

The facilities of the type described here are used for the introduction the loose masses in a container, in which they are brought to a composting center, for example can.

Such systems strive to increase the transport economy often a compression of the loose masses before they are loaded into the transport medium.

This compression is mostly done by a displacement piston that works in a tightly fitting housing, whereby there is a risk of seizure and the compressed An uncertain internal pressure is given to masses.

In contrast, the invention is essentially characterized by the pressing of the waste into a container by means of a pressure piston which slides freely on guide rails in its housing so that it is free from the housing walls. The displacer has a universally hinged plunger so that it can adapt to the resistances occurring on its front side can orientate freely. As a result, the counterpressure of the masses is evenly distributed over the surface of the displacer

The compression pressure aimed at according to the invention is in the order of magnitude of 2 to 10 kg / cm, thus the compressed one Mass easily removed from the somewhat conical container after its transport to the processing center can be and can then easily be brought back into the loose shape, resulting in the removal of metal parts by optical, magnetic or electrical means. The mass can then be used for composting be ground up.

In a further embodiment of the invention, precautions are taken on the displacement device for sprinkling the initially still loose masses with disinfectants, agents for the decomposition of the plastic compounds or other substances, which are useful for composting, for example »This means that the processed masses can also be stored for longer before they are transported to a processing center.

The transport containers can be provided with a slide-on wall that is used to close the compression opening, so that none of the content is lost even with less pressure.

Further details of the invention may now be made with reference to the attached Drawings be described. Show it:

The compressor 10 can be connected to a container via quick-release fasteners 11 and consists of a horizontal one movable ram 12 with a hydraulic working cylinder 13 which is connected to a line system 15. which is supplied by a pump 14 as a function of a sliding control piston 16, whereby the piston 1 can move within the cylinder 13 in one direction or the other. The piston 1 is via a rod 2 with the Ram 12 connected. The reaction force of the hydraulic cylinder 13 is via a ball joint and a universal bearing 4 on a bridge 5 of the housing and thus on the clamped Transfer containers, which keeps the machine in equilibrium during the compression strokes, what their simple storage on rollers 6 is permitted. The battering bear's guardrails give enough play to allow the bear enough Has freedom to transfer largely the same pressure on its front side.

i · 2 zoigt in (JuGrncnnitt one or the stiffeners 54, which lead the bear inside the enclosure. The guides have inclined surfaces to allow waste parts to be deposited and interposed to prevent and can slide-promoting inserts 55 made of Akulon or the like. Have.

The logic and control panel has input contacts 17-20 (Fig. 3) ί to a maximum pressure switch 21 or to limit switches 22 to 24, which are operated by the bear. Furthermore, push buttons 25 to 29 work with these contacts according to the figure 3 together when they press the pushbuttons 30 to 34 of a panel 52 on that shown in FIG Housing are operated. A switch 35 has positions for actuating the motor of the pump 14 and also positions for manual control by means of the push buttons 30 to 34 or alternatively to automatic control of the strokes by the logic shown in Fig. 3 in connection with the timers 8 and 9. The timer 8 is used in the normal workflow, while the timer 9 is used when the load is increased, which is why it triggers an increased stroke frequency.

With 61 an oil collection container is shown, while 62 indicates an oil outlet.

The maximum pressure switch 21 works when the oil pressure rises above the limit value of a safety valve 40, as a result increased resistance.

A different resistance on the ram overturns the same into an inclined position, which is made possible by the universal bearing 4. This tipping is made sufficient by a Allow play in the guide rails.

The housing of the compressor has a filling opening on its upper side 51, through which the loose mass, for example is introduced through a slide.

Brushes 41 are provided on the lower edge of the ram, which clean the bottom of the case and push back loose particles. Before each compression stroke, the loose waste can be sprayed by means of the tank 42 and nozzles 43.

The maximum pressure switch 21 can also trigger an alarm for the operator via a contact 44.

The push button 30 of the push button set 30 to 34 starts the Machine, while the push button 31 triggers the backward movement, the button 32 causes stopping in the maximum retracted position and the button 33 locks the ram in a position in which the lid 45 of the container is closed can be.

From this position a new start can only be made in the Reverse direction, while a new cycle of 45 seconds, for example, only from the extremely retracted position can start out and end in this again; Whenever a stop signal arrives, the ram is arrested.

The automatic backward stroke is initiated when the ram has advanced a fixed depth of, for example, 40 cm or also when the maximum pressure switch 21 is actuated

In addition to the contact 21, the operation is also possible through the Valve 4-0 and through a thermal relay on the motor of pump 14 secured.

A cable 50 connects to the power grid.

The automatic return is terminated by the end contact 20, A new ejection stroke can then be initiated in automatic mode, etc.
