Description

[Detailed description of the invention] The present invention relates to a storage tank in a waste composting device that produces compost by storing waste such as manure, sludge, municipal garbage, etc. in the storage tank and fermenting it while aerating it. It is.

Generally, the fermentation process for composting waste includes two processes: a secondary fermentation process and a secondary fermentation process.

- In the second fermentation step, the decomposition of relatively easily decomposable organic substances in the waste proceeds, and in the second fermentation step, the decomposition of relatively difficult to decompose organic substances in the waste proceeds.

Conventionally, the primary fermentation process in such composting equipment is
-Implemented in a storage tank for secondary fermentation, the secondary fermentation process is -
This is carried out by putting the waste after the secondary fermentation process into a storage tank for secondary fermentation, or by depositing it on the floor, ground, etc.

In this case, the waste usually has a strong bad odor before entering the second fermentation process, but a considerable part of the bad odor usually disappears at the end of the second fermentation process.

However, depending on the type of waste and the fermentation conditions, a considerable odor may remain in the waste after the second fermentation process, which has the disadvantage of deteriorating the environment and causing so-called odor pollution.

On the other hand, through experimentation and observation, the inventor found that if the waste after the next fermentation process is piled up on the ground, the surface layer exposed to the air will disappear in a short period of time. I had gained this knowledge.

The present invention was proposed in view of the above-mentioned drawbacks and based on the above findings, and aims to provide a storage tank in a waste composting device that always makes the waste discharged from the storage tank odorless. It is.

Hereinafter, the configuration of the present invention will be described in detail with reference to the attached embodiment drawings. The storage tank 6 has a charging device 7 for charging waste at the inlet side, and a charging device 7 for scraping out the composted waste at the outlet side. A primary fermentation chamber 9 is provided in the upper part of the interior, and the floor surface thereof is constituted by a breaker rod 4.

Further, the breaker rod 4 and the primary aeration section 1 located below it form a primary aeration device for secondary fermentation.

There is a secondary fermentation chamber 10 in the lower part of the interior of the storage tank 6, and a secondary aeration section 5 is provided at the bottom of the secondary fermentation chamber 10 to provide a secondary aeration device for secondary fermentation. is forming.

The breaker rod 4 has a strip 2 or a spiral strip 3 on its periphery.
The breaker rods 4 are supported substantially horizontally with appropriate spacing corresponding to the properties of the waste, and the breaker rods 4 are arranged parallel to each other. It constitutes the floor surface of the primary fermentation chamber 9.

Depending on the nature of the waste, the overall shape of the floor surface may be a horizontal surface as shown in Fig. 1, an uneven surface as shown in Fig. 3, or an appropriate curved surface as shown in Fig. 4. be done.

Each breaker rod 4 has a gear 11, and although not shown, can be oscillated or rotated in forward and reverse directions by an electric motor.

Of course, the driving device for moving each breaker rod 4 is not limited to gears and electric motors, and may be used to swing or rotate in forward and reverse directions using a known method, for example,
It is also possible to use an actuator, a combination of a lever and a cylinder, etc.

The shapes of the strips 2 are round rods, flat plates, turbine blades, etc., and there are also cases where a spiral-shaped chuck 3 is protruded in place of the strips 2, but these are selected as appropriate depending on the nature of the waste. Ru.

Near the bottom of the breaker rod 4, the primary air diffuser 1 is arranged substantially horizontally.

The sub-diffusing section 1 is formed by drilling a large number of aeration holes 12 in a pipe-shaped body, and is connected to an air inlet 13 .

In the lower part of the secondary fermentation chamber 10, a secondary aeration section 5 is provided which substantially
arranged horizontally.

The secondary air diffuser 5 is formed by drilling a large number of air diffusers 12 into a pipe-shaped body, and is connected to the air inlet 14 .

Air blown from the outside of the storage tank 6 is passed through a large number of air diffusion holes 12 formed on the surfaces of the secondary air diffuser 1 and the secondary air diffuser 5.
It is made to gush out uniformly.

In the embodiment of the present invention configured as described above, the waste input through the input device 7 is deposited in the secondary fermentation chamber 9, and is heated by the air uniformly ejected from the secondary aeration section 1.
Primary fermentation is carried out rapidly, and each breaker rod 4 has a large number of grooves 2 or spiral-shaped chucha 3 around its periphery, and the mutual spacing between them is set to an appropriate value corresponding to the nature of the waste. Since the waste material that comes into contact with each breaker rod 4 does not fall through the gap between the breaker rods 4, it is in a so-called suspended state on a shelf, and the waste material that comes into contact with each breaker rod 4 does not fall through the gap between the breaker rods 4 and is placed on a shelf. Since the weight of the waste stored in the fermentation chamber 9 is carried by the breaker rod 4, the weight of the waste stored in the fermentation chamber 9 is
exerts virtually no pressure on, therefore,
The air sent to the primary diffuser 1 from the air inlet 13 is uniformly blown out without being obstructed by waste, passes between the breaker rods 4, rises, and is deposited in the next fermentation chamber 9. By uniformly aerating the waste, the subsequent fermentation process can be carried out smoothly.

Therefore, when it is desired to move the waste that has been composted through the secondary fermentation process to the secondary fermentation chamber, the breaker rod 4 is swung or rotated to break the suspended state of the waste on the shelf. , let the waste fall down as appropriate.

At this time, when the breaker rod 4 has a strip 2 on the periphery, the waste is scraped off locally, whereas when the breaker rod 4 has a spiral chuck 3 on the periphery, the breaker rod 4 scrapes off the waste locally. The axial transfer action has the effect of destroying the suspended state of waste on shelves and continuously scraping it off.

The shape and arrangement of the competition 2, the size and pitch of the spiral chuck 3, etc. are appropriately selected depending on the properties of the waste.

The waste that has gone through the primary fermentation process has completed the first stage of composting, and its properties are reduced in water content and are almost powder-like with good air permeability.

Therefore, by sending air from the secondary aeration section 5 to the waste deposited in the secondary fermentation chamber 10, it is possible to uniformly ventilate the entire waste.

Therefore, even if odor remains in the waste sent from the second fermentation chamber 9, the odor can be eliminated by aeration as described above.

Further, the composted odorless waste deposited in the secondary fermentation chamber 10 is taken out of the tank by a scraping device 8.

As mentioned above, this invention is based on the idea that above the primary air diffuser holes 1, a plurality of breaker rods 4 each having a large number of breaker rods 2 or spiral breaker rods 3 protruding from the periphery are installed on a substantially horizontal floor. These breaker rods 4 are rotatably supported so as to form a surface.
・Since the waste from the primary fermentation chamber 9 is supported on the top, there is no fixed floor surface, so -order pores 1・
The inflow of air into the waste in the -next fermentation chamber 9 from ... is extremely good, and moreover, the -next aeration section 1...
Since the ... does not come into contact with the waste, the air outlet is not clogged, and the fermentation action is thus sufficiently promoted.

After completing the specified primary fermentation, the breaker rod 4.
The solidified waste is crushed by rotating or swinging the breaker rod 4...
The fermentation material falls into the secondary fermentation chamber 10 through the breaker rod 4, and in this way, it can be transferred very easily using gravity by simply operating the breaker rod 4. Since it does not require any special equipment such as, the structure is extremely simple and inexpensive.

Furthermore, since there is no fixed floor surface, no waste remains, so cleaning and inspection of the inside of the primary fermentation chamber 9 is easy.

Then, the waste crushed by the operation of the breaker rod 4 is sufficiently penetrated by air flowing from the secondary aeration section 5 in the secondary fermentation chamber 10. Therefore, sufficient fermentation is promoted.
