Description

DETAILED DESCRIPTION OF THE INVENTION A. Field of Industrial Application The present invention relates to a continuous fermentation and drying apparatus for automatically fermenting and drying excrement and the like.

Background of the Prior Art In general, in the fermentation composting method of manure, easily decomposable substances in manure are decomposed and removed by the action of microorganisms, and at the same time, fibers, which are difficult to decompose substances, are transformed into humic substances and stabilized. There is a need to. The condition for manure to be able to be used as fertilizer is a moisture content of 65%.
%, and it is necessary to carry out aeration and stirring as a means of supplying oxygen. That is,
Due to the growth and metabolism of aerobic microorganisms, the fermentation temperature increases, evaporation of moisture and bad odor is observed, and at the same time, the decomposition of fibers in the solid material progresses. Therefore, the amount of moisture and solids decreases, and at the same time the malodorous components disappear,
In addition, weed seeds, parasite eggs, and pathogenic bacteria are also killed, making the organic fertilizer hygienic and effective as a soil improvement material. The moisture content of the manure to be processed is 75% to 95%, so 65% is suitable for fermentation.
(moisture content), a preliminary means of adjusting the moisture content is required. As a countermeasure, methods include pre-drying the excrement in the sun, adding dried sawdust as a moisture adjustment agent, and further recycling and reusing some of the fermented and dried feces that have reduced moisture to adjust the moisture content. There are methods. When adjusting the moisture content of manure to a moisture content of 65% suitable for fermentation, pre-drying in the sun etc. requires a large facility area and takes many days, and an inexpensive moisture adjusting material (saw flour) is often used.
When using a moisture adjuster, the required amount to be added is calculated as follows.

X: Amount of water adjustment material added to 1 kg of excrement.

A: Moisture content of excrement.

B: Moisture content at the start of fermentation.

C: Moisture content of moisture adjustment material (saw flour).

X=A-B/B-C (Example) 85-65/65-40=0.8K
g From the above calculation, 0.8 kg of moisture adjustment material is required for 1.0 kg of manure. Incidentally, the bulk specific gravity of sawdust is approximately 260 kg/m ³ when the water content is 40%. Therefore, if sawdust is added to manure every day to adjust the moisture content and fermentation is performed, the volume of the fermenter will be large.
Furthermore, maintenance costs also increase.

C. Prior Art As mentioned above, when fermenting and drying excreta, etc., the moisture content at the start of fermentation must be adjusted to about 65% or less. In order to achieve the appropriate moisture content at the start of fermentation, manure was fermented by adding a moisture-adjusting material to the manure.

D Problems that the invention aims to solve
As in No. 145543, when urine is sprayed after cutting back, the urine creates a flow path, concentrates in one place, flows all at once to the bottom of the fermenter, and often flows out.

E. Purpose of the Invention The present invention prevents urine sprinkled on manure for moisture adjustment from flowing all at once to the bottom of a fermentation tank, and also suctions substances precipitated in the urine storage tank with a pump to produce a fermented and dried product. To provide a continuous fermentation and drying device for excrement and urine, which can be uniformly sprayed and does not require periodic removal of precipitates such as sludge.

F. Means for solving the problem The means for solving the problem according to the present invention is a rectangular parallelepiped having long side walls A1 and A2 and a pipe 15P with ventilation holes 15 at the bottom, as shown in FIGS. 1 to 4. A fermentation tank A with a shape of
A traveling trolley B is mounted on the vehicle, and a urine dispersing section 10' for uniformly distributing urine is disposed at the front of the traveling vehicle B in the running direction, and a urine storage tank is formed by one of the side walls A1 and A2 and the outer tank wall A3. The outlet of the urine dispersion pump 10 for transferring urine, which is movably disposed in the urine storage tank E, and the urine dispersion section 10' are connected and fixed through a feed pipe P1, and also communicated with the urine dispersion section 10'. The outlet of the fixed return pipe P2 is placed in the urine storage tank E, and a rotary blade 3 is placed on the circular track 2 in the center of the traveling trolley B.
It is characterized by a structure in which a turning wheel D equipped with a turning machine C is installed, and while the turning machine C turns the excrement and urine in the fermenter A, a limit switch is used to reciprocate from the start end to the end of the fermenter A. It is what it is.

G. Effect of the present invention According to the present invention having the above-mentioned features, manure to be fermented is deposited in a rectangular parallelepiped fermenter having long side walls and ventilated from the bottom. When the trolley is run while supplying air from the bottom, the turning machine turns the excrement and urine,
When oxygen is evenly supplied and mixed and stirred, it becomes the raw material for compost. Then, the mixed and stirred compost raw materials are transported back and forth between the start and end of the fermentation tank using a running trolley.
While carrying out a portion of the dried excreta, the newly introduced excrement is gradually transferred by a conveyor equipped with a reversing machine. When the running trolley travels to the end of the fermenter, the running trolley is stopped by a limit switch, and the conveyor is moved along with a turning machine on the rotating wheel or on the rotating wheel by a rail, and the end of the fermenter is stopped. Due to the circular trajectory that moves 180 degrees and a half from the top to the bottom, the switchback machine makes a half turn and stops, and then the traveling trolley starts traveling in the opposite direction. When the turning machine is reversed, the traveling trolley travels in the opposite direction, and while traveling again, the processed material can be turned back in the opposite direction on the conveyor. In addition, fluids such as urine and excrement are transferred by a urine spraying pump from a urine storage tank installed on one side of the side wall of the fermenter, and are repeatedly sprayed from a urine spraying unit installed at the front of the traveling truck while traveling. When manure with a high moisture content is thrown in by turning, this and the processed material that has been fermented and dried in advance and transported are cut back by the conveyor of the cutting machine, forming a mixture that moves in a fixed amount at a time.

H. Embodiments of the Invention The present invention will be described in detail below based on embodiments shown in the drawings.

A rectangular parallelepiped fermentation tank A having long side walls A1 and A2 and a pipe 15P with ventilation holes 15 at the bottom is provided, and running rails 1 are laid on the edges of the upper side walls of the fermentation tank A. , a running trolley B is mounted on the running rail 1, and a urine dispersing section 10' is disposed at the front of the running trolley B in the running direction to uniformly spray the urine, and one of the side walls A1 and A2 and a tank outside thereof are disposed. A urine storage tank E is formed by the wall A3, and the outlet of a urine dispersion pump 10 for transferring urine movably disposed in the urine storage tank E is connected and fixed to the urine dispersion section 10' through a feed pipe P1. The outlet of the return pipe P2, which is connected and fixed to the dispersion section 10', is disposed in the urine storage tank E, and furthermore, a rotating wheel D is provided in the center of the traveling truck B, which is equipped with a turning machine C with rotating blades 3 on a circular track 2. is placed thereon, and while the excrement and urine in the fermenter A is turned over by the turning machine C, the fermenter A is moved back and forth between the starting end and the ending end using a limit switch. Then, excrement, urine, etc. and dried feces are stirred and conveyed by rotary blades 3 which are rotated by an electric motor 8 on an endless inclined track of an upper roll 14 from a lower roll 13 of the turning machine C engaged with the rotary wheel D. This relates to the configuration of a continuous fermentation and drying device for excrement. 7 is a rotating electric motor, 6 is a traveling electric motor,
5 is an information board.

As described above, the embodiment of the present invention is equipped with a fermenter A that can blow air from the bottom of the material to be processed through the air blowing hole 15, and a turning machine C equipped with rotary blades 3. It consists of a running cart B that runs on running rails 1 on both side wall edges of the mouth. Therefore,
Manure, etc. to be fermented is deposited in fermenter A, and when traveling trolley B is run while supplying air to this deposit from the bottom, switching machine C switches the manure and dried manure, evenly. When oxygen is supplied and the mixture is deposited while being mixed and stirred, the mixture ferments and becomes a fermented dry product.

When the traveling cart B is reciprocated between the start end and the end end of the fermentation tank A, the excrement and urine thrown on top of the fermented and dried material is turned over by a turning machine C equipped with rotary blades 3 and moved and deposited. When the running trolley B travels to the end of the fermenter A, the running trolley B is stopped by a limit switch (not shown), and the turning machine C runs on the rotating wheels 16 together with the rotating wheel D. Fermenter A
Rotate 180 degrees and a half from A to B. When the rotary electric motor 7 is turned on and the rotary drive wheel 17 rotates, the rotary drive wheel 17 is engaged with the circular orbit 2 of the rotary wheel D, so the circular orbit 2 causes the rotary wheel D and the rotary drive wheel 17 to rotate. The turning machine C rotates half a turn and stops, and then the traveling truck B starts traveling in the opposite direction, that is, toward the starting end. When the turning machine C is reversed, the traveling cart B can turn the workpiece on the opposite side in the opposite direction by the turning machine C while traveling again from the terminal end to the starting end side. Then, the traveling trolley B stops when it travels to the starting end side, but the turning machine C again turns the processed material while moving on the rotating wheels 16 together with the turning wheel D, and makes a half turn from A to B of the fermenter A. . When moving half a turn, after conveying the fermented and dried material to the place where the excreta is input, while carrying it out, when the turning machine C is reversed, the traveling trolley B is again traveling towards the terminal side.
The fermented and dried product is stirred and conveyed and completely stopped at the starting point. In this way, the processed material is processed by the turning machine C.
It is moved and deposited in the opposite direction to the direction in which the turning machine C moves. As the movement and accumulation is repeated, excrement, urine, etc. are fermented and dried, and the fermentation tank A is rotated and moved. The urine and excrement fluids can be fermented and dried by repeatedly spraying them from the urine spraying section 10' on the way to the fermented and dried material using a urine spraying pump from a urine storage tank provided on one side of the side wall of the fermentation tank.

Urine can then be sprayed on the fermented mixed product before it is cut back with a cutter. Note that when urine is sprayed after cutting back, the urine creates a flow path, concentrates in one place, flows all at once to the bottom of the fermenter, and often flows out. Therefore, if it is cut back before it flows out, it will be well mixed with dried matter such as feces, and fermented and dried.

By using a submersible pump for the urine dispersion pump 10, urine can be uniformly sprayed over the entire surface of the fermentation tank with one low-power dispersion pump, and the return pipe P2
By adjusting the valve so that 60% to 80% of the urine of the pump capacity is returned to the urine storage tank E from the outlet of the pipe P2, the urine to be returned to the urine storage tank E is forcefully squirted out from the return pipe P2. Since the urine is stirred by
The precipitated substances can be sucked up by the pump 10 and evenly distributed over the fermented and dried product, and there is no need to regularly remove precipitates such as sludge.

Since a ventilation hole 15 is installed at the bottom of the mixture accumulation tank, the air blown from the ventilation device 11 can promote fermentation of the treated mixture and at the same time remove moisture upward to produce a fermented and dried product. . Since the rotating wheel D is equipped with a turning machine C having rotating blades 3, it conveys a certain amount and at the same time crushes the lumps of excrement, supplies oxygen on average, and further promotes fermentation and drying. It is something useful.

Effects of the Invention In the present invention, since the urine scattering section is disposed at the front of the traveling cart (that is, the front side of the turning machine), urine can be sprayed before the fermented mixture is turned back by the turning machine. I can do it. For this reason, the urine does not flow all at once to the bottom of the fermentation tank, but if it is turned back before flowing out, it is well mixed with dried matter such as feces, and is fermented and dried.

By using a submersible pump for the urine dispersion pump,
Urine can be uniformly spread over the entire surface of the fermenter with one low-power dispersion pump, and 60% to 80% of the pump capacity can be returned to the urine storage tank from the return pipe outlet. By adjusting the valve, the urine sent back to the urine storage tank is vigorously jetted out from the return pipe and stirred, so the substance that settles in the urine storage tank is sucked up by the pump and evenly distributed over the fermented and dried product. There is no need to regularly remove deposits such as sludge.

By providing the urine tank along one side of the side wall of the fermentation tank, the side wall of the urine tank can be placed on one side, eliminating the need for concrete work on one side, and the urine tank of the present invention can be used as a urine tank in a livestock barn. It can also be used in combination, and urine can be processed at low cost.
