Description

[Detailed Description of the Invention] (Industrial field of application) This invention relates to a vertical fermenter for fermenting livestock manure, industrial waste, and the like, and more specifically, for preventing the gas in the tank from leaking to the outside when the fermented material is introduced. Regarding technical means.

(Prior Art) Conventionally, a fermenter has been used as an apparatus for fermenting livestock manure to compost. In this kind of fermenter,
There is a vertical type fermenter in which livestock manure collected from a hopper provided at the top of the tank is put into the tank.

By the way, in this type of fermenter, when the lid of the hopper is opened and the livestock manure is put into the tank, the gas in the tank leaks to the outside, but conventionally, the gas leak has not been so much a problem. In the case of a fermenter for treating livestock manure, it is often used in a place that originally has an odor even if there is a livestock building in the surroundings, and the gas leakage in the tank itself was not a problem.

However, in recent years, this type of fermenter has been increasingly used for treating food wastes and other industrial wastes, and in this case, the gas leakage becomes a serious problem.

(Means for Solving the Problems) The present invention has been made to solve such problems, and its gist is to introduce fermented products such as livestock manure and industrial waste from a hopper at the top of a tank. In a vertical fermenter configured to ferment in a tank, the hopper is provided with an inner lid and an outer lid that can be opened and closed to form a double lid structure, and a temporary storage chamber is formed between the inner lid and the outer lid. In addition, the opening / closing drive device for the inner lid and the outer lid is provided.

(Operation and Effect of Invention) As described above, in the present invention, since the hopper has the double lid structure, it is possible to prevent the odor in the tank from leaking to the outside when the fermented product is charged. Specifically, when the fermented product is put into the hopper while the inner lid is closed and the outer lid is opened, the fermented product is once received in a temporary storage chamber formed between the inner lid and the outer lid. Then, when the outer lid is closed and then the inner lid is opened, the fermented product is dropped into the tank.

That is, according to the present invention, the fermented product can be supplied into the tank in a state where the inside and the outside of the tank are blocked.

In addition, when the inner lid is opened, the gas in the tank enters the temporary storage chamber between the inner lid and the outer lid, but the gas is deodorized by the degassing device before the outer lid is opened when the next fermentation product is added. It may be guided to the device.

(Example) Next, the Example of this invention is described in detail based on drawing.

In FIG. 2, 10 is a vertical fermenter as an example of the present invention, which has a tank 12 and a hopper 14. The hopper 14 is provided on the upper side of the upper opening 15 of the tank 12 as shown in FIG. 1, and has front and rear wall portions 16 and 18 which are opened in the shape of an inverted figure, and also the inverted figure of the same. And the left and right wall portions 20 and 22 (FIG. 3) in an open shape. An inner lid 24 and an outer lid 26 are openably and closably provided on the lower portion (the portion where the opening 15 is formed) and the upper portion. The inner lid 24 is rotatably supported by a shaft 28 as shown in FIGS. 4 and 5, and is connected to the first cylinder 32 via an arm 30 as shown in FIG. The cylinder 32 is opened and closed. The cylinder 32 is provided on the frame 34 via a shaft 36, and is rotatable about the shaft 36 when the inner lid 24 is opened and closed.

On the other hand, the outer lid 26 has a mountain-shaped cross section, and is rotatably supported by the shaft 25 at the base end portion thereof. Further, a mounting member 38 is fixed near the top portion thereof and is connected to the second cylinder 40 via the mounting member 38. The second cylinder 40 is also fixed to the frame 43 via a shaft 51 so that it can be rotated around the shaft 51 when the outer lid 26 is opened and closed.

The wall portion 16 of the hopper 14 has a lower inclined surface 40 that rises at a steep angle and an upper second inclined surface 42 that extends at a slightly gentle angle, and the outer lid 26 has the second cylinder 40. With the rotation by, the tip end is brought into contact with the second inclined surface 42. Thus the outer lid 2
The abutting portion between 6 and the inclined surface 42 is sealed by the seal member 44. This seal member 44
As shown in FIG. 6 (A), has a fixing portion 46 and an action portion 48 having a circular cross section.
The working portion 48 is in direct contact with the inclined surface 42. Incidentally, the base end portion of the outer lid 26 and the wall portion 18
The seal between the seal member 4 and the seal member 4 as shown in FIG.
It is supposed to be done by 5. Seal member 45
The structure is similar to that of the seal member 44 and is composed of a fixed portion 47 and an operating portion 48.

Further, the contact portion between the inner lid 24 and the peripheral portion of the opening 15 is also sealed by the seal member 50.
As shown in FIG. 6 (C), the sealing member 50 also has a fixing portion 52 and an operating portion 54 having a circular cross section, and the fixing portion 52 is fixed to the tank body side. Touches the inner lid 24.

Next, the operation of the double structure portion of the hopper 14 in this vertical fermentor will be described.

When fermented products such as livestock manure and industrial wastes are put into the hopper 14 by a predetermined conveyor device with the inner lid 24 closed and the outer lid 26 opened, the fermented products are first temporarily stored in the hopper 1.
It is received in the temporary storage room in 4. The accommodation room is
The capacity is sufficient to accommodate a proper input amount once.

Now, when the fermented product is put into the hopper 14, the outer lid 26 is closed by the second cylinder 40, and the fermented reaction in the tank 12 is performed for a certain period of time, that is, until the supply timing of the fermented product is reached. To do. Then, when the supply timing comes, the inner lid 24 is opened by the first cylinder 32 and the fermented material in the hopper 14 is dropped into the tank 12 through the opening 15. At this time, since the outer lid 26 is in the closed state, the gas in the tank 12 does not leak outside.

After dropping the fermented product into the tank 12, close the inner lid 24,
Then, when the inner lid 24 is opened, it enters into the hopper 14 from the inside of the tank 12 to process the gas. That is, the gas in the hopper 14 is guided by a blower to a deodorizer, where it is deodorized and discharged to the outside.

When this process is completed, the outer lid 26 is opened again, the fermented product is put into the hopper 14, and the same operation as above is repeated again.

As described above, according to this example, it is possible to effectively prevent the gas in the tank 12 from leaking to the outside as it is when the fermentation product is charged.

Although the embodiments of the present invention have been described in detail above, the present invention can be applied to various types of vertical fermenters, and various modifications are made without departing from the scope of the invention. It is configurable.
