Abstract

PURPOSE:To realize the sharp volume reduction treatment of garbage and to utilize garbage as fertilizer or the like by draining garbage under compression and moving the drained garbage in one direction in a fermentation tank under heating and stirring to bring the same to a dried fine powder state. CONSTITUTION:In such a case that a garbage treatment device is arranged to the sink of a general house, garbage is successively charged in a first treatment tank 2 from a charging port 8a and successively pressed and compressed in one direction by a rotary screw 7 to be drained. Next, the garbage compressed to about 1/3 as a whole is transferred into the first fermentation chamber 13 heated to about 60 deg.C by supplying a current to a heater winding 18 of a second treatment tank 3 through a communication pipe 9 and fermented in the presence of fermentation bacteria using rotary stirring rods 17 while dried under heating. By successively performing these drying and fermenting actions even in second and third fermentation tanks 14, 15, the garbage is treated to be formed in a powder state and discharged to a recovery container 4 by a taking-out pipe 19 after the elapse of about 60hr.

FIG. 3 shows a case where the processing apparatus according to the present invention is installed on a sink, and the height of the main body case 1 is 370 mm.
Inside the one with a depth of 200 mm and a length of 450 mm, the first processing tank, the second processing tank, and the collection container as shown in FIGS. 1 and 2 are stored and installed. It is placed in the box 24 and the charging pipe 8 is placed in the water tank 2.
It is connected to 5. Although the drainage pipe is not shown, it is connected to the drainage main. It should be noted that the treatment apparatus according to the present invention can be installed in the storage box of the main sink as long as the lid is detachably attached to the input port, but it is installed in the auxiliary water tank of the auxiliary sink that is not used very often. Is desirable.

Now, 50 g of actinomycetes in a soil bacterium, which is a type of fermentation bacterium, is introduced into the first fermentation chamber 13 in the second treatment tank 3 through an inlet (not shown), and then the drive motor 20 is turned on. ON
Then, after the heater winding 18 was energized, 450 g of garbage including various miscellaneous matters was prepared and sequentially charged into the first treatment tank 2 through the charging port 8a. Then, the garbage enters the inner cylindrical body 6 through the charging pipe 8, is sequentially pressed in one direction by the rotating screw 7 and is drained while being compressed, and is compressed to about 1/3 as a whole. In that state, they were sequentially transferred into the first fermentation chamber 13 of the second treatment tank 3 via the communication pipe 9. On the other hand, water and other water containing raw garbage and generated by being compressed by the screw 7 were collected inside the outer cylindrical body 5 through the small holes 6a and drained through the drain pipe 5a. The garbage transferred to the second processing tank 3 has already been stirred by the stirring bar 17 at 60 r.p.m. p. Since it was rotating at m, it was stirred in the presence of the fermenting bacterium, and was subjected to the fermenting action by the fermenting bacterium while being heated and dried at about 60 ° C.

After maintaining this state for about 24 hours, 450 g of raw garbage was again charged through the charging port 8a, and after a further 24 hours while keeping the heating and stirring state, a further 450 g of garbage was added. I put garbage. Raw garbage sent into the second treatment tank 3 is about 60 in the presence of fermentation bacteria.
The mixture is stirred by the stirring rod 17 while being heated to ℃,
Transferred from the fermentation chamber 13 to the second fermentation chamber 14 and the third fermentation chamber 15 while changing the form into powder, and when about 60 hours have passed since the first input of raw garbage, the take-out pipe 1
From 9, the brown, free-flowing powdery substance was discharged into the recovery container 4. With the cycle and the operating condition as described above, it was possible to continuously feed the garbage for one week and continuously maintain the recovery of the powdery material. This powdery substance is an organic substance and can be used as it is as a fertilizer or a soil conditioner.

Since the screw 7 does not have to be constantly rotating, as shown in FIG. 2, the clutch device 26 is attached to the rotary shaft 12 and the sensor (not shown) is attached to the feeding pipe 8 to feed the garbage. Only when the sensor is operated, the sensor detects it, or separately, a switch is provided for pressing each time, and this switch is turned on to operate the clutch device 26 for a certain time or until it is turned off to rotate the screw 7. It is good to Clutch device is rotating shaft 1
6 may be provided, or from the rotary shaft 16 to the rotary shaft 12
The drive force transmission means to the gear mechanism may be provided in this gear mechanism. Further, a drive motor for driving only the rotating shaft of the screw may be separately provided, and may be configured to be turned on and off by the above-described sensor or switch. The rotating shaft for rotating the stirring rod is always rotating in the forward direction or the reverse direction, and the rotation speed thereof is 60 to 70 r.p.m. p. m.

The means for compressing and dewatering raw garbage in the first treatment tank may be, for example, a piston or the like which operates when the raw garbage is intermittently charged in addition to the screw. The powdery material may be stored in the collection container 4, or may be collected in a bag by attaching a bag mouth to the extraction tube.

The means for heating the inside of the second processing container 3 is, in addition to the embodiment, heated the rotating shaft, the stirring rod, or the partition plate,
In addition, various means for heating by high frequency heating, electromagnetic induction heating, hot air, etc. can be used. Regarding the volume reduction rate of raw garbage, when 450 g of raw garbage was added in another experiment and compression dehydration was performed with a screw in the first treatment tank, the volume was reduced to about 1/3. The volume-reduced raw garbage was heated and stirred in the second treatment tank under the same conditions as above for 60 hours continuously, and when it was taken out, the volume was further reduced to 1/3. From this, it was found that the overall volume reduction rate was 1/9.

The above-mentioned embodiment is an apparatus in which a family of four is planned to produce 450 g of garbage per day.
If the number of families is large and the amount of raw garbage produced in a day is large, a larger capacity will be used.

[0019]

Since the present invention is constructed as described above,
It is compact in size and does not occupy a lot of space, and can easily reduce the volume of raw garbage that is difficult to dispose of in homes and public incinerators in a form that is easy to store. The effect that it can be reused as an improving agent can be exhibited.
