Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus suitable for treating garbage produced in large amounts on a daily basis.

[0002]

2. Description of the Related Art Conventionally, when a large amount of raw garbage generated from various restaurants, large-scale retail stores such as supermarkets, and various food processing establishments is self-processed, generally,
For example, a means for incinerating by using fuel such as kerosene or heavy oil is known. 80-95% of the food waste is water,
As a processing procedure, heat is added to this water to vaporize it, dehydrate it, and then burn it to incinerate it.

[0003]

By the way, in order to vaporize a large amount of water in garbage, a large amount of heat is required, and there is a problem that fuel cost rises significantly.

It is an object of the present invention to remove raw water by removing water to reduce the amount of the raw garbage, thereby reducing the processing cost without requiring a high fuel cost as in the incineration method. To provide.

[0005]

In order to achieve this object, an apparatus for treating food waste according to the present invention comprises a storage tank having an inlet and an outlet for garbage and storing the garbage in a substantially sealed state. A storage tank that encloses and stores almost the entire storage tank and that has a substantially sealed condensation space between the storage tank and the outer surface of the storage tank, and drains the condensed water generated in the condensation space; To the condensing space of the condensing tank via the discharge pipe,
The compressor is provided with a compressor that compresses the vapor generated in the storage tank and sends it to the condensation space.

[0006]

By the operation of the compressor, the internal space of the storage tank is sucked to a negative pressure, and the vapor generated from the garbage is compressed to a predetermined pressure by the compressor and sent to the condensation space of the condensation tank. The temperature of the condensation space rises and a difference from the temperature in the storage tank occurs. Due to this temperature difference, condensed water droplets are condensed on the outer peripheral surface of the storage tank. Condensed water drops drip and are stored as condensed water (drain) in the lower part of the condensation tank and drained. In the storage tank, a small amount of raw garbage that has been dried by dehydration is taken out from the discharge port.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the garbage disposal according to the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the main structure of the raw garbage processing apparatus of the embodiment is a storage tank 10 having a raw garbage input port and a discharge port and storing raw garbage in a substantially sealed state, and a storage tank. A condensing tank 20 that encloses and accommodates substantially the entire 10 and has a condensing space 22 that is substantially sealed between the accommodating portion and the outer surface of the storage tank 10, and drains the condensed water generated in the condensing space 22; Inhalation pipe 31 in storage tank 10
And a compressor 30 which communicates with the condensing space 22 of the condensing tank 20 via a discharge pipe 32 to compress the vapor generated in the storage tank 10 and send it to the condensing space 22.

Storage tank 1 arranged vertically in the vertical direction
In No. 0, a raw garbage input port 13 is provided in the upper portion of the main body 11, and a lid member 14 is hinged to the input port 13 so as to be half-rotatable so that the lid member 14 can be opened by the weight of the input raw garbage. .. Further, a discharge port 15 for taking out the processed garbage is provided in the lower part of the main body 11, and a normally closed lid member 16 is hinged to the discharge port 15 so as to be rotatable halfway. When the lid members 14 and 16 of the input port 13 and the discharge port 15 are closed, the main body 11 is in a substantially sealed state, and the sealed space is used as a storage space 12 for storing garbage.

Further, the condensing tank 20 is one size larger than the storage tank 10, and almost all of the condensing tank 2 is from the outside.
It is housed so as to wrap it through 2. Condensation space 22
Is a substantially sealed space that faces and contacts most of the outer surface of the main body 11 of the storage tank 10. A drain pipe 23 is provided at the lower bottom of the main body 21 of the condensation tank 20,
Condensed water (drain) 25 accumulated on the lower bottom is drained by a drain pipe 23.
It can be drained from. A drain valve 24 is provided in the drain pipe 23. The drain valve 24 closes the drain pipe 23 in a normal state, for example, and opens the drain pipe 23 when the condensed water 25 has a sufficient amount. Is used.

On the other hand, the storage tank 10 and the condensation tank 20
The suction side and the discharge side of the compressor 30 are connected to. That is, the suction port of the compressor 30 communicates with the storage space 12 in the storage tank 10 via the suction pipe 31, and the discharge port communicates with the condensation space 22 in the condensation tank 20 via the discharge pipe 32. As shown in the drawing, the suction pipe 31 is provided outside the condensing tank 20 of the storage tank 10 and is provided at the charging port 1.
It is connected to the upper part of the storage tank 10 close to 3. The compressor 30 is driven by a motor 40, and sucks the storage space 12 of the storage tank 10 to a negative pressure by operation, compresses the intake air to a predetermined pressure, and sends it to the condensation space 22 of the condensation tank 20. There is.

The storage tank 10 and the condensation tank 20
The material of is not particularly limited here, but it has a required corrosion resistance against moisture in handling raw garbage, has a pressure-resistant rigidity that can withstand compression by the compressor 30 described below, and is also cost-friendly. It is desirable to select one.

Next, the operation and action of the garbage disposal according to the embodiment having the above construction will be described.

Raw garbage is dropped into the storage space 12 from the input port 13 of the storage tank 10, and a certain amount of raw garbage is stored in the storage space 12. At the time of processing, the compressor 30 starts to operate when the motor 40 is turned on.

By the operation of the compressor 30, the storage tank 1
The storage space 12 of 0 is sucked through the suction pipe 31 to have a negative pressure, and the water in the garbage is evaporated by the suction. This vapor is compressed until it reaches a predetermined pressure and is sent from the discharge pipe to the condensation space 22 of the condensation tank 20. The compression ratio of the compressor 30 is preferably 2 to 5, for example. This compressed vapor raises the temperature of the condensing space 22 in the condensing tank 20 and causes a difference from the temperature of the storage space 12 in the storage tank 10. Due to this temperature difference, water droplets condensed on the outer surface of the main body 11 of the storage tank 10 are condensed (indicated by a symbol W) in the condensation space 22. Condensed water droplets drop and are stored in the lower part of the condensation tank 20 as a drain 25. When the drain 25 is small, the drain pipe 23 is closed by the drain valve 24. When the amount of drain 25 increases to a certain extent, this drainage valve 24 causes the drain pipe 23 to drain due to this buoyancy.
Float in the direction of opening. The drain 25 is discharged from the drain pipe 23 to the outside.

In the storage tank 10, the storage space 12
Due to the negative pressure and the temperature difference from the side of the condensation tank 10, the moisture in the raw garbage is evaporated, and the raw garbage dehydrated in this way becomes a dry state and is taken out from the lower discharge port 15. The taken out garbage can be used as fuel, for example. Further, the drain 25 discharged from the condensing tank 20 can be effectively used as hot water.

In the case of the apparatus of the embodiment, the amount of heat required for dehydrating and drying raw garbage is equivalent to the amount of work heat of the compressor 30 by the operation of the motor 40, and this heat equivalent is the conventional incineration system by fuel combustion. It is an energy-saving system with extremely high thermal efficiency, which is only 1/5 to 1/25 of the heat quantity of. Further, when the device is considered as a kind of heat exchanger, the storage tank 10 that contacts the condensation space 22 of the condensation tank 20.
It will be readily appreciated that the greater the outer surface area of the, the greater the thermal efficiency.

The ozone generator 50 is used in the apparatus of the embodiment.
By providing a system for supplying ozone to the storage tank 10, the garbage stored in the storage space 12 can be sterilized and the unpleasant odor can be deodorized. Therefore, it is possible to wipe away the contamination image of this type of device and maintain the environment for processing garbage properly.

[0019]

As described above, the food waste treatment apparatus according to the present invention requires significantly less heat than a conventional incineration system using fuel, and can reduce fuel cost and facility cost. ..
