Abstract

PROBLEM TO BE SOLVED: To make it possible to maintain crude refuse at adequate components and to efficiently treat the crude refuse with high-activity microorganisms at a low driving power cost. SOLUTION: A perforated plate 2 is arranged on the bottom of a treating vessel 1 and an air accepting chamber 3 is disposed on the lower side thereof. Air is introduced by an air pump 4 into the air accepting chamber 3. Agitating vanes 6 are installed in a crude refuse housing chamber 5 on the upper side of the perforated plate 2. The air contg. moisture rising in the crude refuse housing chamber 5 flows between a tray 14 and a heat radiation plate 13 from an air inlet port 19 and comes into contact with the heat radiation plate 13. By which moisture is condensed. The water drops fall onto a tray 14 and are discharged via a drain pipe 16 from a drain port 18. The heat radiation plate 13 is cooled with air by the natural ventilation heading toward a discharge port 11 from an air suction port. The water from the drain port 18 is received in a suitable container and is supplied at need into the crude refuse housing chamber 5.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a garbage processing machine capable of discharging excess water from a tank.

[0002]

2. Description of the Related Art In order to treat food waste with a food waste disposer, it is necessary to send air into the processing tank in order to supply oxygen to the food waste and microorganisms contained in the processing medium. Further, in order to keep the activity of microorganisms high, it is necessary to maintain the temperature inside the tank appropriately. In addition, it is necessary to discharge from the mixed layer of the raw waste and the treatment medium to the outside of the machine, other than the water necessary for maintaining the activity of the microorganisms, of the water brought into the raw waste and the water generated by the decomposition of the raw waste.

In order to meet such a need, in addition to forcibly supplying air into the processing tank by a pump or fan and maintaining the temperature in the tank by heating with a heater or heat retention with a heat insulating material, etc. Then, excess water is evaporated and discharged with the exhaust air to the outside of the system.

[0004]

In the above conventional example, when the water content of the raw garbage in the raw garbage storage chamber is insufficient, it cannot be compensated for, and the raw garbage processing efficiency is reduced.

[0005]

In the garbage disposal of the present invention, the bottom is partitioned by a ventilation plate, an air receiving chamber is formed below the ventilation plate, and the garbage storage chamber is located above the ventilation plate. In a raw garbage processing machine provided with a raw garbage processing tank in which is formed, a processing medium stored in the raw garbage storage chamber, and a stirring blade installed in the raw waste storage chamber, A heat radiating plate is disposed above the heat radiating plate, and a ventilation chamber through which air circulates is provided above the heat radiating plate, and a tray for collecting water is provided on the lower side of the heat radiating plate in an inclined manner. An air inlet for guiding air from the lower part of the garbage storage chamber between the heat sink and the heat sink, and a drain pipe for discharging water on the tray to the garbage processor is connected to the lower side of the tray. Installed an exhaust fan that discharges air from between the heat sink and the tray to the outside of the garbage processor. It is an butterfly.

In the garbage processing machine of the present invention,
Moisture released upward from the mixed layer of garbage and processing medium is
It is drawn by the exhaust fan and flows between the heat sink and the tray. Then, it is cooled by the heat radiating plate to become water drops, which fall on the tray. The water on the tray is discharged through the drain pipe. By supplying this water into the raw garbage storage chamber as needed, it is possible to prevent the water content of the raw garbage from excessively decreasing.

It is preferable to provide a device such as a pump for returning the recovered water.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a sectional view of a garbage disposal according to an embodiment. A porous plate 2 is arranged at the bottom of the processing tank 1, an air receiving chamber 3 is provided below the porous plate 2, and air is introduced into the air receiving chamber 3 by an air pump 4. Perforated plate 2
An agitating blade 6 is installed in the raw garbage storage chamber 5 on the upper side. The stirring blade 6 is rotated by a motor 7.

A lid 8 is attached to the upper part of the processing tank 1 by a hinge 9 so as to be openable and closable. An intake port 10 is provided on one side wall of the lid 8, and an exhaust port 11 is provided on the other side wall.
Is provided.

A ventilation chamber 1 is provided between the intake port 10 and the exhaust port 11.
2, the lower surface of the ventilation chamber 12 is partitioned by the heat dissipation plate 13. A tray 14 is provided below the heat dissipation plate 13 so as to face the heat dissipation plate 13. Tray 1
4 is inclined so that one end side is high and the other end side is low, and a drain pipe 16 is connected to a drain port on this low side via a flexible joint 15. An exhaust fan 17 and a drain port 18 are provided at the end of the drain pipe 16. An air inlet 19 is provided on the higher side of the tray 14.

A processing medium is stored in the garbage storage chamber 5. As the processing medium, sawdust, chaff, rice bran, coconut chips, etc. are used. The periphery of the garbage storage chamber 5 is covered with a panel heater 20.

In order to dispose of the garbage by this garbage processor, the lid 8 is opened, the garbage is put into the garbage storage chamber 5, and the stirring blade 6 stirs and mixes the garbage and the processing medium. The pump 4 supplies the air into the air receiving chamber 3, and the fan 17 discharges the air from the garbage storage chamber 5.

The amount of air sent by the pump 4 is so small that oxygen is supplied to the microorganisms,
The power consumption by the pump 4 is reduced.

The stirring of the raw dust and the processing medium by the stirring blade 6 does not lower the temperature of the raw dust in the storage chamber 5, and the excess water from the mixed layer of the raw dust and the processing medium contains the raw dust in the storage chamber 5. Use a slow or low-frequency material that is discharged to the upper space to reduce power consumption by stirring.

With this, low power consumption, yet sufficient oxygen is supplied to the microorganisms to supply sufficient oxygen, to properly maintain the water content in the mixed layer of raw garbage and the treatment medium, and to mix the raw garbage and the treatment medium. By maintaining the internal temperature at an appropriate temperature of about 60 ° C. and sufficiently enhancing the microbial activity, it is possible to perform microbial treatment of garbage.

The moisture-containing air that has risen in the garbage storage chamber 5 flows from the air inlet 19 between the tray 14 and the heat radiating plate 13 and comes into contact with the heat radiating plate 13 to condense water. This water drop falls on the tray 14 and is discharged from the drain port 18 via the drain pipe 16. The heat radiating plate 13 is air-cooled by natural ventilation from the intake port toward the exhaust port 11.

The water from the drain port 18 can be received in an appropriate container and supplied into the garbage storage chamber 5 if necessary.

In the present invention, as shown in FIG. 2, a tank 21 is connected to the drain port 18 and a sprinkler 23 is provided in an upper part of the garbage storage chamber 5, and water is pumped into the garbage storage chamber 5 by a pump 22. Spraying is preferred. In this case, it is preferable that the ventilation resistance sensor 24 detects the ventilation resistance of the contents in the garbage storage chamber 5, and the controller 22 operates the pump 22 when the detected value falls below a predetermined value. .

[0019]

As described above, according to the garbage processing apparatus of the present invention, the garbage can be maintained at an appropriate water content and efficiently treated with highly active microorganisms.
