Description

Technical Field

[0001] The utility model relates to the technical field of the treatment of livestock manure and planting waste, and particularly relates to a manure fermentation house. Background Art

[0002] A manure fermentation house is a facility used to treat organic waste such as livestock manure. It mainly converts organic substances into stable humus and gas products, such as carbon dioxide and water vapor, through the action of aerobic microorganisms, thereby realizing the recycling of resources and the reduction of pollution. Manure fermentation houses are widely used in livestock farms, agricultural waste treatment centers, etc. By building a manure fermentation house, centralized treatment and resource utilization of organic waste such as livestock manure can be achieved, improving the environmental protection level and economic benefits of the farm.

[0003] Chinese patent document CN216726178U discloses a manure leachate treatment device, which includes a collection tank arranged beside the manure pile. The top plane of the collection tank is lower than the bottom plane of the manure pile for collecting the leachate of the manure pile; a sewage discharge pipe, one end of which is arranged in the collection tank. The sewage discharge pipe is provided with a sewage discharge port communicating with the collection tank, and the sewage discharge port is lower than the top plane of the collection tank. A collection tank with a horizontal plane lower than the manure pile is arranged beside the dry cow manure pile for collecting the leachate after the manure pile ferments. At the same time, a sewage discharge pipe with a horizontal plane lower than the collection tank is arranged in the collection tank. After the leachate flows into the collection tank, it precipitates in the collection tank. The manure residue is located at the bottom and the clarified liquid is located at the upper part. When the leachate in the collection tank is enough and the liquid level exceeds the sewage discharge port, the upper clarified liquid is discharged from the sewage discharge port. When there is more manure residue in the collection tank, the manure residue in the collection tank can be cleaned and then reused.

[0004] The existing technology has the following deficiencies: In the existing technology, the manure residue is piled up in the manure fermentation house in a large area. The water in the manure residue enters the sewage discharge pipe for discharge after filtration. In the actual use process, the manure water generated by the manure residue is viscous after filtration, with low fluidity. The sewage discharge pipes need to be distributed in the manure fermentation house, and the length of the pipes is relatively long. The manure water with a high solid content often blocks the sewage discharge pipes after deposition and is not easy to dredge, resulting in too high a moisture content of the substrate and hindering the normal progress of fermentation. Content of the Utility Model

[0005] In order to solve the technical problems that the manure water with a high solid content is easy to deposit and block the sewage discharge pipe and it is difficult to clean the manure pool, the utility model provides a manure fermentation house, which includes a fermentation house body, a manure pool and a fermentation bed floor. The characteristics are that the manure pool is horizontally arranged transversely in the fermentation house body, and a plurality of longitudinal inclined water collecting grooves are arranged on the fermentation bed floor. A water filtering plate and a filtering net are arranged on the water collecting grooves. The highest point of the water collecting groove is an open mouth, and the lowest point of the water collecting groove is connected to a sewage circulation pool through a concealed pipe.

[0006] For the convenience of composting, the fermentation bed floor is located on the left and right sides of the manure pit. The water collecting tank includes an upper water collecting tank and a lower water collecting tank. A liquid passing channel is provided below the manure pit. The upper water collecting tank and the lower water collecting tank are connected by the liquid passing channel, so that the leachate of the fermentation substrate reaches the buried pipe and enters the sewage circulation tank.

[0007] For the convenience of sewage discharge, the buried pipe is horizontally arranged, and the sewage circulation tank is located in the middle of the buried pipe and is the lowest point of the overall structure.

[0008] To prevent the dregs and solids from blocking the buried pipe, the buried pipe is connected to a plurality of first sump pits, and the first sump pits are distributed on the left and right sides of the sewage circulation tank.

[0009] For the convenience of pumping manure and dregs during cleaning, a second sump pit is provided in the manure pit.

[0010] Preferably, the second sump pits are provided at both ends of the manure pit.

[0011] For the convenience of evenly arranging the manure and sewage, a manure and sewage transportation pipe is provided above the manure pit, and a plurality of sewage discharge ports are provided on the manure and sewage transportation pipe.

[0012] For the convenience of transporting the manure residue to realize production rotation, both sides of the fermentation house body are of a double-door structure, and the double doors respectively correspond to the fermentation bed floors on the left and right sides of the manure pit; it is beneficial to discharge fertilizer from both sides, ensuring that production can be easily rotated for operation and saving funds.

[0013] To reduce the fine material of the fermentation substrate from falling into the water collecting tank along with the leachate, cover plates and filter barrier nets are provided on the open sump pits of the water collecting tank. The utility model has the following beneficial effects:

[0014] 1. It is not easy to block the pipeline and is convenient for cleaning. After the filtered manure water enters the water collecting tank, it flows along the slope and converges into the sewage circulation tank through the buried pipe, and it is convenient to spread the manure residue onto the fermentation bed floor through the manure pit for drying; the segmented structure of the water collecting tank shortens the length of a single ditch, and the height difference at both ends is small during slope setting, reducing the construction difficulty; a plurality of sump pits are provided, and the wastewater enters the sewage collection tank, reducing the number of blockages of the conveying pipeline; when pumping manure and dregs for sewage discharge in the future, it can be pumped clean, avoiding the problem that the flat-bottom design method may cause the inability to pump clean during future maintenance.
