Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of discharging a waste container by air extraction, wherein the waste container is connected via a first valve to a waste supply line such as a waste chute of an apartment building. In addition, it is configured to be connectable from the waste discharge line to the automobile waste collection chamber via the second valve actuation opening at the bottom of the container, and said collection chamber is extracted with air to achieve the required suction. The effect is achieved and the interior of the container is arranged to communicate with the ambient air via at least one valve actuation opening.

A vacuum-evacuated waste container as described above is disclosed in European Patent Application No. 84850111-0.

However, this known container-based drainage technique has many disadvantages in practical use.

Since the evacuation of the container is controlled by a garbage truck located outside the building's litter compartment, after a complete evacuation, a complete evacuation of the system must be ensured along with the function of the waste container. . Garbage containers are usually discharged at regular intervals, most commonly once a week, so if the garbage container fills up much faster than expected, a garbage bag will be placed on the lower part of the garbage chute above the inlet valve of the container. Are piled up, which leads to the closure of the lower part.

In the above-mentioned patent specification, the connection between the container and the supply line, ie, the waste chute, is to prevent the risk of injury to the person using the waste chute during the discharge of the container during the whole discharge process. It must be closed over.

For the reasons mentioned above, it is not possible to inspect the lower part of the waste chute above the first valve, so that the above-mentioned excessive packing is not observed and the container is discharged. Often occurs during. This is a significant interruption of service when reusing the container.

The discharge technique defined in the above mentioned patent specification also requires the rapid introduction of atmospheric air into the extracted waste container, which causes severe distortion of the container and shock waves. Even sonic booms propagate within the entire system.

As a result, and also it becomes clear that the external air flow supplied to the container should not be directed exclusively to the bottom layer of the internal refuse, which is as described above. This is because, first of all, the air flow keeps the dust bag in a disturbed state. Therefore, the desired discharge from the waste bag discharge line is not achieved.

On the contrary, even if the external air is supplied exclusively through the opening provided at the top of the container, the desired extraction effect on the dust collected in the bottom part of the container is not achieved.

The purpose of the waste container discharge system according to the present invention is to eliminate the above-mentioned drawbacks, to ensure the optimum discharge of the waste container, to keep the distortion of the waste container material at a predetermined level, and then to further shoot. The disassembly of the stoppage of the possibility that the mouth will be blocked by the waste bag accumulated here ensures the reusable reuse of the waste container, and the bag can also be dropped into the waste container according to the discharge, It is to provide an emission method.

Another object of the present invention is to achieve optimum venting of the container by controlling the introduction of external air into the container.

This is in accordance with the invention the above-mentioned process, in particular the next extraction process carried out after connecting the container to the motor vehicle collection compartment, ie a) the first extraction process with the first valve open. B) after at least a partial vacuum is created in the container,
A second extraction step in which external air is introduced below the debris collected on the collecting area of the container, and c) a third external air flow is additionally supplied to the upper level of the debris collecting area inside the container. And the extraction step of.

By opening the first valve during the initial state of discharge, the dust collected in the dust chute above the first valve is drawn into the container and falls.

When the first external air stream is introduced into the container through the bottom opening of the container, the debris is levitated and held in a disturbed state. A valve is provided at the opening in the container below the waste collection area. Optimal waste discharge is achieved by simultaneously feeding a second external air stream to the upper level of the waste collection area inside the container.

According to a preferred embodiment of the invention, the first valve is repeatedly opened and closed during the first extraction step, whereby
The waste collected in the waste chute above the valve moves safely.

According to a second embodiment of the invention, an external air flow is introduced into the container during the entire discharge process, which reduces the stress on the material and, for example, into the extracted container. The acoustic bangs generated when the external air is rapidly introduced are prevented. It should be noted that the air supply amount continuously increases during the vacuum generation in the container.

According to the invention, said continuous supply of external air into the container is achieved by leaving the first valve slightly open during the full discharge state.

Alternatively, by opening the first valve and / or an opening with a valve, this opening is located in the upper part of the container, ie above the waste collection area. It is also possible to introduce further external air flow into the container by supplying more air into the container.

The present invention will be described in detail below with reference to the accompanying drawings showing an embodiment of the above-mentioned waste container.

FIG. 1 shows the components of a refuse container (generally designated by the reference numeral 1), which is preferably placed in the refuse room of a building. The waste container 1 is connected to a waste chute 3 via an opening 2 and said opening is controlled by a valve 4. A waste discharge line 5 is provided at the bottom of the container, and said line 5 is connectable via a valve 6 to the collection chamber of a waste truck (not shown). Air can be extracted from this collection chamber by known means, and thereby achieves the suction effect required for discharging the waste container 1.
At the bottom of the container below the refuse collection area 7 in the container, an opening 8 is provided, and this opening 8 is provided with a valve and constitutes the inlet for the external air flow in the lower part of the collection refuse. The upper part of the container can also be provided with a valve control opening 9 for introducing a secondary air flow at a level above the waste collection area 7.

The discharging process of the container according to the present invention comprises the following steps. That is, the valves 4 and 6 are the first
Opened during the extraction process. As a result, the dust accumulated above the valve 4 in the chute 3 is sucked into the container 1 and descends. At this stage, the valve 4 is repeatedly opened and closed, which guarantees the cleaning of the jammed chute 3 from the lower part.

Then, the valve 4 is first closed and after the vacuum has been created in the container 1, the bottom valve 8 is opened and external air is introduced into the bottom of the container 1 below the accumulated refuse. be introduced. As a result, the dust is floated from the bottom of the container 1 and held in a disturbed state inside the container.

In order to move this refuse quickly and maximally, both valve 4 and valve 9 are opened, a secondary air stream is introduced into the container, and this air stream removes the refuse. Transport to 5 safely.

In an alternative embodiment of the present invention,
The valve 4 and / or the external air inlet 8 are opened slightly during the entire discharge process. This prevents the sudden introduction of external air into the container and avoids excessive strain and undesired sonic shock loading on the container, as described above.

The operation of the valve is automatically controlled by the garbage collection vehicle when the discharge line is connected in a predetermined state. At the end of the discharge process, all valves are closed except the waste inlet valve.

However, the invention is not limited to the embodiments shown, but many design variations are possible within the spirit of the invention described in the appended claims.
