Description

Apparatus for garbage decomposition and disposal

The present invention relates to a treatment apparatus for decomposing living waste.

Conventionally, an approximately cylindrical suction cylinder is installed vertically from the bottom position of the treatment tank where water is spread to the lid side, and an ejector portion is formed with a part of the suction cylinder to a large diameter, and the air supply pipe in the ejector There is a known living waste disposal apparatus in which an air blower formed at the front end is mounted upward, and a diffusion plate for diffusing air sucked into the upper end of the suction container and an exhaust control lid for directing exhaust are known (for example, Japanese Patent No. 2704713). Moreover, the arrangement | positioning of the evaporation solidification tank and the deodorizer in the outer position of a decomposition tank is also known (for example, refer Unexamined-Japanese-Patent No. 11-169825).

Conventional raw waste (food waste) decomposition processing apparatus has a function of separating the water when foaming phenomenon occurs, but the foaming phenomenon is remarkably increased as the processing capacity, for example, the air supply amount is increased, The capacity is limited, and in case of leakage of each part of the apparatus, for example, the upper lid part, odor gas flows out of the cracking tank, and especially when the small capacity is transferred to use the circulation pump. Since clogging caused by rubbish is easily generated, there is a problem in that the operating cost is high because it requires or another power source.

In view of these problems, the present invention suppresses the foaming phenomenon itself, and provides a biowaste decomposition treatment apparatus which does not leak out of the decomposition tank even if a leaking point occurs, and also contributes to a reduction in operating cost. It was invented for the purpose of doing so.

A water pressure gauge is attached to the ceiling section of the treatment tank main body and the radiator separation chamber located above the ceiling of the treatment tank main body for processing the living waste in the treated water spread in the tank, and controlled by the negative pressure by the suction force of the blower. The rider mixture generated in the tank is sucked with a negative pressure, and the rider passage gap and the exhaust passage gap formed in the rider separation chamber are passed through to separate the rider and destroy foaming. Connect the slurry state raw waste supply pipe on the suction side of the transfer air lifter for transporting the live garbage to the ceiling of the negative pressure, extract the residue, and blow out the air from the waste supply pipe on the suction side of the air lifter with the negative pressure in the tank. It is connected to each of the dregs drying tank which is negatively pressured by suction of the air branch pipe, and is transported by suction.

In addition, when the diameter of the diffuser plate 4 is 100 mm, the radix gap 10 with the exhaust control part 9 is 20 mm, and the upper surface 11 of the exhaust control part 9 and the lower surface of the radix separator 7 are shown. If the exhaust passage gap 13 formed at (12) is 20 mm, good results are obtained.

Next, regarding the conveying air lifter 30, the total height H is 200 mm, the bottom diameter R is 65 mm, the introduction diameter of the inlet pipe 32 is 25 mm, and the diameter of the slurry-type live garbage supply pipe 34 is as follows. This is 15 mm, and the diameter of the atmospheric suction pipe 33 is 10 mm, whereby good results are obtained.

Next, a description will be given of a case of carrying out the present invention. When the blower 26 is operated by injecting water to the height of the water surface W in the treatment tank main body 1, the water separation chamber (via the vacuum pipe 27) 3) Since the pressure difference between -420 mmAq inside and the treatment tank ceiling T and the inside of the separation chamber 3 becomes negative pressure 40 mmAq, the radix mixture is attracted by the above-mentioned negative pressure from the branch pipe 19 of air. It becomes (K) and is inhaled. The elevated radix mixture K impinges on the diffusion plate disc 4 and diffuses around, and water flows into the lower treatment tank body 1 along the inclined plate of the truncated cone exhaust control unit 9. And here it is separated from the air component, passes through the rider passage gap 10 and the exhaust passage gap 13 and is in contact with the rider separation plate 7, and after removing and removing the water, a part of the rider separated water is separated from the precipitation pipe. It flows down from 14, and air component is discharged | emitted from the vacuum piping 27. As shown in FIG. More specifically, when the water having a foaming phenomenon rises in a vacuum action, it is pulled out of the gap between the rider passage gap 10 and the exhaust passage gap 13, which causes a sudden drop in pressure, so that the foam breaks finely here. Suppresses foaming phenomena easily.

In addition, the raw waste that is introduced into the input crushing tube 31 and crushed in the slurry state is transferred to the conveying air lifter 30, but in this case, the slurry state unprocessed supply pipe 34 of the conveying air lifter 30 is negative. A pressure (approximately 400 mmAq) is acting, and the sludge-like raw waste is sucked up by the vacuum effect, is raised in the slurry-type raw waste supply pipe 34, and is supplied into the processing tube main body 1.

The debris of raw waste accumulated on the tank bottom 16 is then extracted and sent to the dreg drying tank 38 through the air lifter 35. More specifically, when the lid drying tank 38 is closed, the inside of the air vent pipe 49 becomes negative pressure due to suction by the vacuum from the air branch pipe 19, and the inside of the inner box 45 also becomes negative pressure. Therefore, the inner side of the waste feed pipe 39 connecting the inner side of the waste drying tank 38 to one end becomes negative pressure, and thus, the waste (N) of living waste introduced from the water tank bottom surface 16 in the waste extracting air lifter 35. Is sent into the dreg drying tank 38 and fed into the extraction net 46. And drying of dregs is performed by the air which blows off from the bottom of the inner side box 45. FIG.

Moreover, since the other end of the exhaust heat exhaust pipe 50 which connected one end part with the deodorizer exhaust outlet pipe 23 is connected in the exhaust heat recovery groove 44 of the waste drying tank 38, It blows out from the exhaust blower hole 24 of the deodorizer exhaust inlet pipe 22 from the exhaust inlet pipe 28 of a discharge side into the deodorizing activated carbon 20, and also the exhaust entry hole 25 of the deodorizer exhaust outlet pipe 23. The exhaust gas of high temperature which flowed in from) is supplied to the exhaust heat recovery groove 44, and it is heated from the bottom part, and it promotes the drying effect of the garbage of a living waste.

More specifically, by heating with a heating heater 48, it is heated to about 70 to 100 ° C. for sterilization at the time of further heating and drying residue extraction in the cold.

As described above, according to the present invention, by forming a strong negative pressure closing circuit in the treatment tank main body and the water separation chamber, the foaming phenomenon can be controlled, and the air lift transfer using the negative pressure can be carried out, so that clogging caused by garbage can be prevented even with a small capacity transfer. This reduces the operating cost, and also allows the system not to blow out the odor gas because each part is negative pressure even if a leak point occurs in the device.
