Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention crushes raw garbage such as vegetable waste, fish waste, and leftover food discharged from the kitchen and other refuse (hereinafter referred to as kitchen waste), The present invention relates to a garbage treatment device in which this is directly vacuum-conveyed together with air to a wastewater treatment device through a vacuum sewer pipe.

[Conventional technology]

Generally, kitchen waste discharged from the kitchen is classified into sewage and other solid waste, which is discharged to the sewage as it is. We have collection work vehicles collect it.

In addition, some households with a high standard of living are equipped with a garbage disposal device equipped with a disposer for crushing garbage and a dehydrator. In this device, the kitchen waste is first crushed with a disposer, then separated into water and solids by a dehydrator, and only the water is discharged to a sewer pipe, and the solids are stocked to a specified amount and discharged regularly. I am trying to do it.

[Problems to be Solved by the Invention] However, in the kitchen waste disposal method in which the kitchen user takes out and classifies the raw garbage, and packs and collects the garbage, the garbage is classified and bagged each time the garbage is generated. It was necessary to squeeze it in, which was extremely complicated and troublesome for a housewife at home.

In addition, in the kitchen waste processing apparatus including the disposer and the dehydrator, the disposer and the dehydrator are expensive and the overall apparatus is extremely expensive, so that it cannot be popularized. In addition, this garbage processing device has a drawback in that it requires a portion for stocking solids, which makes the entire device large. Further, the stock content of the stock has to be taken out again when it reaches a predetermined amount, packed in a bag, and collected by a collection work vehicle, which is still disadvantageous.

[Means for solving the problem]

The present invention, which has been improved and removed in view of the above-mentioned conventional problems, crushes raw garbage finely into filth, which is vacuum-conveyed together with air to a sewage treatment apparatus through a vacuum sewer pipe. It is intended to provide a processing device.

Thus, the means adopted by the present invention to solve the above-mentioned problems are a disposer for crushing garbage, a tank for storing crushed waste, and one side connected to a vacuum sewer pipe and the other. A suction pipe disposed so that the side is located on the bottom side in the tank from the upper side of the tank, a vacuum valve disposed in the middle of the suction pipe, and a position above a predetermined water level in the tank. In addition, there is provided a garbage disposal device comprising an air inlet provided in the suction pipe and a water level detector for detecting the water level in the tank and controlling the opening / closing of the vacuum valve.

[Work]

The kitchen waste finely crushed by the disposer is stored together with the waste water in the waste tank. When the water level reaches a predetermined level, the water level detector opens the vacuum valve.
As a result, the vacuum in the vacuum sewer pipe acts on the tank,
The waste in the tank is sucked into the vacuum sewer pipe and vacuum transferred to this. In that case, air is simultaneously sucked from the air suction port formed in the middle of the suction pipe. That is, the dirt in the tank is vacuum-conveyed in the vacuum sewer pipe together with the air.
This is because the vacuum pressure must be increased if only the dirt is transported by vacuum, and the vacuum pressure can be lowered by carrying it together with air. The filth transported in vacuum is treated by a sewage treatment apparatus, purified, and then discharged into a river or the like.

When the water level in the tank drops, the water level detector detects this and closes the vacuum valve. Therefore, the vacuum transfer of the waste is stopped, and the waste from the kitchen at home is sequentially stored in the tank.

Therefore, if the device of the present invention, the dehydrator is unnecessary, and the finely crushed garbage of the garbage can be directly conveyed to the sewage treatment device through the vacuum sewer pipe, and the labor of the kitchen user can be greatly simplified. It is a thing.

〔Example〕

The structure of the present invention will be described below based on the embodiments shown in the drawings.

1 and 2 relate to an embodiment of the present invention, and FIG. 1 is a partially enlarged vertical sectional view of a garbage processing apparatus 1,
The figure is an overall schematic view of the garbage processing apparatus 1. As shown in the figure, the garbage treating apparatus 1 of this embodiment is provided with a disposer 3 below the sink 2 for finely crushing the garbage. Then, on the discharge side of the disposer 3, a storage tank 4 for storing filth consisting of crushed kitchen waste solids and sewage is installed adjacently.

A suction pipe 5 is installed in the storage tank 4 in the vertical direction. One side of the suction pipe 5 is connected to the vacuum sewer pipe 6, and the other side is arranged from the upper side to the lower side of the storage tank 4, and the suction port 5a is located on the bottom 4a side of the tank 4. There is. A vacuum valve 7 is installed in the middle of the suction pipe 5. The vacuum valve 7 has valve bodies 8a and 8b made of a flexible material such as rubber arranged vertically opposite to each other, and a central portion thereof is biased by a spring 9 or the like so that the valve bodies 8a and 8b are in close contact with each other. There is. Upper and lower chambers 10a divided by the valve bodies 8a and 8b,
10b is connected to the vacuum sewer pipe 6 through a bypass line 11. A three-way valve 13 controlled by a water level detector 12 installed in the storage tank 4 is installed in the middle of the bypass line 11. The three-way valve 13 normally connects the upper and lower chambers 10a and 10b of the vacuum valve 7 to the atmosphere. When the water level detector 12 gives an instruction, the upper and lower chambers 10a and 10b are connected to each other.
0b is connected to the vacuum sewer pipe 6.

An air inlet 14 is formed in a portion of the storage tank 4 located above the water surface of the suction pipe 5.

On the other hand, the vacuum sewage pipe 6 is connected to an ejector section 17 of an outflow pipe 16 installed in the adjusting tank 15 or the like of the sewage treatment apparatus. The pump 18 is driven so that the waste water in the adjusting tank 15 is discharged to the outflow pipe 16
When it is supplied to the anaerobic tank or the like by the above, a negative pressure is generated in the ejector portion 17, and the inside of the vacuum sewer pipe 6 becomes a vacuum state. Normally, the entire system is driven in this state.

Next, an operation mode of the embodiment apparatus 1 configured as described above will be described.

First, kitchen waste such as vegetable scraps, fish scraps, and leftover foods generated in the kitchen is thrown into the disposer 3 from the sink 2 and crushed into extremely fine pieces. Then, the crushed kitchen waste is sequentially stored in the storage tank 4 as waste together with the waste water.
Subsequently, when the water level in the storage tank 4 reaches a predetermined water level, the water level detector 12 detects this and switches the three-way valve 13, and the vacuum sewer pipe 6 and the vacuum valve 7 through the bypass pipe line 11.
The upper and lower chambers 10a and 10b are communicated with each other. Therefore, vacuum pressure acts on the upper and lower chambers 10a and 10b, and the valve bodies 8a and 8b
b expands in the vertical direction in FIG. 1 against the biasing force of the springs 9, 9. That is, the vacuum valve 7 is opened.

As a result, the inside of the storage tank 4 comes into communication with the vacuum sewer pipe 6, and the dirt is sucked from the suction port 5a of the suction pipe 5, and at the same time, the air is sucked from the air suction port 14. Therefore, the filth in the storage tank 4 together with the air is the vacuum sewer pipe 6
The inside of the tank will be transported by vacuum, and the adjustment tank of the sewage treatment device will be
Supplied to 15. In this case, the reason why the filth is conveyed together with the air is that if only the filth is conveyed, a considerably large vacuum pressure is required to suck the filth,
This is because the vacuum pressure can be lowered by mixing air and transporting it together with air. The waste transported to the adjusting tank 15 is subjected to a predetermined treatment, purified, and then discharged into a river or the like.

In this way, when the suction and transfer of the waste in the storage tank 4 progresses and the water level in the tank drops, this is detected.
Is detected and the three-way valve 13 is opened to the atmosphere. That is, the upper and lower chambers 10a and 10b of the vacuum valve 7 are communicated with the atmosphere. As a result, the valve bodies 8a and 8b of the vacuum valve 7 are urged by the springs 9 and 9 to come into close contact with each other, and shut off the communication between the storage tank 4 and the vacuum sewer pipe 6. After that, the wastes from the sink 2 and the disposer 3 are sequentially stored in the tank 4.

When the suction port 5a side of the suction pipe 5 is clogged during the vacuum transfer of the waste from the storage tank 4, the water level of the waste increases abnormally. However, in the garbage treating apparatus 1 of this embodiment, the air suction port 14 functions as an overflow port, and it is possible to sequentially suck the filth with the air from the air suction port 14 and carry it to the vacuum sewer pipe 6 in vacuum. .

By the way, the present invention is not limited to the above-described embodiment, and can be appropriately changed. For example, vacuum valve 7
Although the time for which the opening operation is performed is set based on the signal from the water level detector 12, it may be controlled by a timer. Further, the shape, size, number, installation location, etc. of the air intake port 14 are arbitrary.

〔The invention's effect〕

As described above, in the present invention, it is possible to omit the dewatering device of the conventional garbage processing device, and the cost can be reduced accordingly. Further, the finely crushed garbage of the garbage can be conveyed as it is to the sewage treatment apparatus through the vacuum sewer pipe, and the labor of the kitchen user can be greatly simplified. In addition, the air intake port functions as an overflow port, so that the waste does not overflow from the storage tank.
