Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a tank for treating manure efficiently.

[0002]

2. Description of the Related Art In toilets provided in trains or mobile toilets used in outdoor exhibitions, it is required to efficiently treat excrement and prevent odors from being emitted. .

Conventionally, in a raw water tank for treating manure and urine, an organic deodorant is added to the organic solid matter such as feces or paper, but the liquid portion above the solid matter is crushed or decomposed. Although it is used again for cleaning the toilet bowl, when feces and urine accumulate in the raw water tank, the reaction between corroded feces and the drug may increase the foul odor.

On the other hand, organic solid matter such as feces or paper is cultivated at the bottom of the raw water tank with microorganisms such as soil fungi to react with the organic solid matter, which is condensed and separated from the liquid portion. There is a method of providing a bioreactor that enables the bioreactor.

This method is excellent in reducing the accumulation of malodor associated with the deposition of organic solids.

However, since the reaction process by the microorganisms gradually progresses, it is not possible to sufficiently deal with the efficient treatment of manure.

[0007]

DISCLOSURE OF THE INVENTION The present invention, in a raw water tank, crushes organic solids speedily to sufficiently accelerate the condensing action by a bioreactor, thereby separating the organic solids and liquid in the raw water tank. It is an object of the present invention to provide a manure treatment tank that can be efficiently separated and can prevent a bad odor due to the accumulation of organic solids.

[0008]

In order to solve the above-mentioned problems, the constitution of the present invention is such that in a raw water tank, a dropping portion of excrement is surrounded by a mesh, and a sharp projection is formed inside the mesh. Having a crushing arm for crushing organic solid matter such as feces and paper, an air jet nozzle for circulating the internal manure and a bioreactor section for condensing the injected organic solid matter by microorganisms. It consists of a manure treatment tank due to the provision.

[0009]

Based on the above-mentioned structure, in the present invention, the solid organic matter is moved and circulated by the jetting force of the air jetting nozzle, in which case the organic solid matter is made to collide with the crushing arm and crushed sequentially. It is a translation.

The mesh is provided around the crushing arm by concentrating a large amount of organic solid matter in the mesh,
This is to increase the frequency of collision with the crushing arm.

The organic solids pulverized by the crushing arm propagate a microorganism that condenses the organic solids such as soil fungi and provides a bioreactor at the bottom for performing the condensing action. Separation of organic solids and liquids is facilitated.

Further, when the crushing arm is not simply caused to exist in the mesh but is rotated and moved in the raw water tank,
The crushing action is drastically accelerated, and the crushing operation of organic solids can be speeded up.

When the air from the air jet nozzle is supplied to the bioreactor side, the condensing action of microorganisms is further promoted.

Embodiment 1 FIGS. 1A and 1B are a side sectional view and an upper sectional view showing a typical embodiment of the present invention.

As shown in these figures, in the present application, in the raw water tank 1, the area where the manure falls and the microorganisms
In the state where the bioreactor 2 for decomposing organic solid matter such as paper is surrounded, two-stage meshes 6 and 7 having different vertical stages are provided.

The provision of the two-stage meshes 6 and 7 prevents the liquid portion from passing easily to the outside of the mesh when the decomposed organic solid matter adheres to the mesh due to the reaction with microorganisms. To do so.

However, it is not an indispensable requirement of the present invention that the mesh is a two-stage mesh having the above-mentioned vertical steps.

The crushing arm 3 provided on the inner side surrounded by the meshes 6 and 7 is shown in FIG. 1 (a), FIG. 1 (b) and FIG.
As shown in FIG.
Upright, and the arms are formed in a shape in which the arms project radially from the support column in a plurality of upper and lower stages, and each arm 3 is provided with a sharp protrusion 31, and the protrusion moves and circulates in the raw water tank. It sticks into the solid organic matter such as droppings and paper and crushes it.

When the crushing arm 3 is rotated to positively crush the organic solid matter, an external drive motor is provided and the rotary shaft and the wall of the raw water tank are the same as in the electric washing machine. At the crossing point of, a mechanism that shuts off the liquid is essential.

A blower pipe 12 is inserted into the raw water tank 1 and air is ejected from the raw water tank 1 to move and circulate organic solids inside the raw water tank. The blower pipe 12 extends to the bioreactor 2 site. Then, air is sent to promote condensation of organic matter by microorganisms such as soil fungi.

In Example 1, the reaction stone 10 having a capillary structure is used as the inner wall of the raw water tank,
This leads to the humification of the organic solid matter due to the feces leached to the outside of the meshes 6 and 7, promoting the aggregation and contributing to the separation from the liquid portion.

In Example 1, not only the crushing arm 3 unique to the present invention but also the bioreactor 2 in the raw water tank,
By using the reaction stone 10 and the like together, the crushing and decomposition of the organic solid and the adsorption of the organic solid are promoted.

The meshes 6 and 7 have the function of concentrating the organic solid matter in the vicinity of the crushing arm 3 and, at the same time, culturing the soil fungus so that the polycondensation reaction is promoted outside the mesh, thereby improving the coagulation deodorizing ability. By increasing the height, the liquid portion used for cleaning the toilet plays a role of promoting the separation of the organic solid matter and the liquid portion.

In Example 1, the condensed organic solid matter is discharged from the sludge discharge section 9, and the organic solid matter remaining without being condensed by the bioreactor 2 moves to the outside of the meshes 6 and 7, This is the reaction stone that forms the inner wall 1
0 significantly promotes aggregation and complete solid-liquid separation.

In Example 1, the liquid leached out of the mesh is circulated by the deodorizing power and sterilizing power of soil bacteria and used for washing the toilet bowl.

[0026]

[Embodiment 2] FIG. 2 shows an embodiment in which a settling tank 20, a filtration tank 30, and a water purification tank 40 are sequentially attached to the raw water tank 1 shown in Embodiment 1 and installed.

In the structure of Example 1, a large amount of organic solid matter is discharged from the sludge discharge hole 9, and a considerable amount of the remaining organic solid matter is promoted by the reaction stone 10 forming the inner wall to promote the agglomeration effect to humus. Be guided. As a result, solid-liquid separation and adsorption of solid matter are enhanced to form purified water.

However, the structure of Example 1 cannot completely separate the organic solid matter and the liquid.

Therefore, in the second embodiment, the settling tank 20 is provided adjacent to the raw water tank 1, and the raw water tank 1 and the settling tank 20 are communicated with each other through the pipes 21 at the respective upper portions, and the mesh of the raw water tank 1 is formed. A liquid containing an organic solid is taken into the settling tank 20 from the outer side and the upper layer, and the organic solid is allowed to settle down.

A filter tank 30 is provided adjacent to the settling tank 20, and the upper portions of both are connected via a pipe 31.

In this case, the supernatant portion of the settling tank 20 is further flown into the filtration tank 30, the organic solid matter contained in the liquid is filtered, and the liquid that has passed through the filtration tank 30 is mostly organic solid matter. Is not contained.

A water purification tank 40 is provided adjacent to the filtration tank 30,
When they are communicated with each other through the pipe 41 in the lower part, the liquid in the filtration tank moves to the water purification tank 40.

In the water purification tank 40, when silica stones are further catalyzed, efficient water purification is promoted, and the resulting liquid can be circulated and used as a toilet liquid for cleaning.

[0034]

As described above, according to the present invention, a crushing arm is provided in the raw water tank to efficiently crush the organic solid matter such as feces and paper, and then the odor is condensed and deodorized by the bioreactor. Since the organic solids in the raw water tank can be separated from the liquid portion and the organic solids can be discharged to the outside, it is possible to prevent the reaction between the deodorant and the organic solids in the conventional mobile toilet. As a result, it becomes possible to clean the toilet bowl without any bad odor.

Further, by using the bioreactor and the reaction stone, which are the conventional techniques, in combination, the inherent actions of these are further promoted, and the above-mentioned effects are made more remarkable.

When a sedimentation tank, a filtration tank and a water purification tank are attached to the raw water tank having the function and effect of the crushing arm of the present invention, the separation of the organic solid matter and the liquid is completed, and it is pure. Since the liquid can be deodorized, it is possible to avoid a situation such as a conventional mobile toilet in which the odor remains or increases in the circulating liquid.
