Description

[Detailed Description of the Invention] (Industrial field of application) The present invention is a fermentation stirring device that ferments fermenting organic matter such as pig manure while stirring, and prevents odors generated during stirring from being emitted to the outside world. The present invention relates to a fermentation stirrer equipped with a device.

(Prior Art) Generally, in a fermentation stirrer for an organic substance, the organic matter is mechanically stirred to efficiently perform a fermentation process to obtain a compost or the like.

(Problems to be solved by the invention) This fermentation process has a problem that a large amount of foul odor is generated during mechanical agitation and diffuses to the surroundings, and it does not stop inside the processing plant, and significantly damages the surrounding local environment. . Therefore, conventionally, the entire fermentation tank is covered and exhausted, and this is recovered and deodorized by a chemical bath or soil.

However, according to the conventional deodorizing means, the apparatus for exhaust treatment becomes large and the cost increases, so that there is a problem that the production cost of the fermented product also rises.

The present invention has as its basic purpose the solution of the above problems, and provides a fermentation stirring device which has a simple structure and can prevent the diffusion of malodor at low cost.

(Means for Solving the Problem) In order to solve the above-mentioned problems, the present invention has an air collecting hood arranged above an agitating part of an organic matter, and sends the collected gas into the organic matter to the air collecting hood. The base end of the trachea is connected, a pump is interposed in the air supply pipe, and the tip is opened in the organic substance.

That is, this invention is a fermentation stirring apparatus for fermenting an organic substance while stirring it. In a fermentation stirring device, a stirrer equipped with a vertical stirring means and a front-back stirring means is movably installed on the organic material tank, and the stirring section of the stirrer is covered above. An air collecting hood and an auxiliary cover for closing the rear are arranged, and an air feeding pipe composed of an intake pipe and a discharge pipe for collecting gas and feeding it into an organic substance is connected to the air collecting hood, and a pump is connected to the air feeding pipe. The fermentation stirring apparatus is characterized in that it is interposed and the tip thereof is inserted and opened in the organic material that has been stirred.

(Operation) According to the present invention, the malodor generated from the organic matter at the time of stirring is sucked into the air collecting hood, and then the air containing this malodor is
It is blown into the organic matter by the air pipe. Therefore, the malodor is circulated in the path from the vicinity of the organic matter to the air collecting hood, the air supply pipe, and the vicinity of the organic matter, and the leakage of the malodor to the outside of the path is prevented as much as possible. Moreover, most of this malodor is mixed and absorbed in the organic matter, so that the malodor can be more effectively prevented from spreading.

(Embodiment) An embodiment of the present invention will be described below with reference to the accompanying drawings.

Fermented fertilizer 2 is stored in the oblong fermenter 1,
A partition wall 3 is provided in the central portion along the longitudinal direction. A self-propelled stirrer 4 having a width of about half the width of the fermentation tank 1 is arranged in the fermentation tank 1.

This agitator 4 is provided with drive wheels 5 ... 5 at the center of the side surface thereof, and a vertical agitating rotary 6 is disposed at the lower front portion in the traveling direction (direction A in the drawing) with its rotation axis hanging down. Further, the main stirring rotary 7 is arranged with its rotation axis horizontal.

In addition, an aeration hood 8 is provided in the rear part of the agitator 4 over the entire width so as to cover the fermentation and fertilizer 2 below. On the upper surface of this air collection hood 8, there are three odor suction sub-pipes.
8a ... 8a are continuously provided, and the sub pipe 8a is provided with an odor intake main pipe 8b (intake pipe) continuously in the width direction. The main tube 8b has a flexible tube 8c
Of the flexible tube 8c is connected to the suction port of the odor suction blower 9. On the other hand, one end of a flexible tube 10a is connected to the outlet of the blower 9, and the other end is connected to an odor discharge main pipe 10b (exhaust pipe) along the width direction. Five odor discharge pipes 10 ... 10 which are air supply pipes are suspended from the odor discharge main pipe 10b.

The above-mentioned odor discharge pipe 10 is bent backward at a substantially right angle, and the bent portion is inserted into the fermented fertilizer 2 with stirring.

At the rear end of the air collecting hood 8, an auxiliary cover 11 made of a rubber plate that reaches the fermentation and fertilizer 2 is hung down.
Is closed and the upper part of the fermented fermented fertilizer 2 with stirring is leveled.

Next, the operation of this stirring device will be described.

By operating the drive wheels 5, the stirrer 4 self-propels in the fermentation tank in the direction A in the figure.

On the other hand, the vertical stirring rotary 6 and the main stirring rotary 7 rotate on their respective rotary shafts, and the fermentation fertilizer 2 is
Fermentation is promoted by supplying oxygen that is vertically stirred by the vertical stirring rotary 6 and is stirred forward and backward by the main stirring rotary 7.

The rear end of the agitator 4 is closed by an auxiliary cover 11. Further, by the operation of the blower 9, the bad odor at the rear part of the stirrer 4 is sucked into the air collecting hood 8, and the sub pipe 8a, the main pipe 8b, and the flexible tube 8c.
It is sent to the suction port of the blower 9 via (intake pipe, etc.). This bad odor further passes through the blower 9, the flexible tube 10a, the main pipe 10b and the discharge pipe 10 (exhaust pipes such as) from the outlet, and is blown into the fermented fertilizer 2 from the tip thereof. And most of the bad odor is absorbed by the fermented fertilizer which became porous. The air containing other bad odors is sucked into the air collecting hood 8 from the vicinity of the fermentation and fertilizer 2, and the air containing bad odors circulates in the path.

Therefore, it is possible to prevent the malodor from spreading to the outside of the stirring device.

In addition, in this embodiment, the bad odor is sucked by the air collecting hood,
Although it was blown out by the air supply pipe and circulated as it is, it is also possible to measure the removal of the malodor by placing a filter for treating malodor in the middle of this route.

(Effect of the Invention) As described above, according to the present invention, the air collection hood is arranged toward the organic matter, and the air supply pipe for supplying the gas collected by the hood to the organic matter is directed toward the organic matter. Since it is placed, it prevents the diffusion of the atmosphere including bad smell,
There is an effect that the deterioration of the surrounding environment can be efficiently prevented by an inexpensive device.

Further, when the tip of the air supply pipe is arranged so as to be inserted into the organic substance, there is an effect that a part of the malodor is absorbed by the organic substance and the emission of the malodor can be prevented more effectively. Further, the auxiliary cover cooperates with the air collecting hood to prevent the emission of odor as much as possible, and it is possible to smooth the top of the agitated organic matter.
