Device and method for mechanically cleaning manure of leaky pigsty

Abstract

The invention relates to a device for mechanically cleaning manure of a leaky pigsty. The device comprises the pigsty and is characterized in that: the bottom of the pigsty is provided with at least one manure leaking plate; at least one manure trough is arranged below the manure leaking plate; the bottom of the manure trough is provided with at least one inclined plane; the lower side of the manure trough is provided with a drainage ditch; scrapers used for cleaning the manure and driven to reciprocate by a motor driving mechanism are arranged in the manure trough; and the motor driving mechanism comprises a motor, steel ropes connected with the scrapers and driven by the motor, and guide wheels for guiding the ropes. Meanwhile, the invention also relates to a pigsty structure and a corresponding method for mechanically cleaning manure of a leaky pigsty. By the invention, the manure sewage discharging amount can be reduced, the total amount of organic pollutants can be decreased, and the invention has the advantages that: the cost is low, the operation is simple and convenient, the manure cleaning efficiency is high, the discharge reduction effect is good, the pig manure which is mechanically cleaned and collected has low water content and is easily subjected to subsequent concentrated composting reutilization and the like.

Description

technical field [0001] The invention relates to a mechanical manure cleaning device and method for a slatted pig house, which is particularly suitable for clean production of manure pollution reduction in large-scale pig farms. Background technique [0002] The rapid development of the large-scale pig farming industry has solved the problem of ensuring the supply of pork non-staple food for urban and rural residents, but the discharge of feces and sewage from large-scale pig farms has also caused serious pollution to the rural environment. In order to solve the problem of fecal sewage discharge reduction in large-scale pig farms, the traditional cleaning methods for pig farms generally use manual manure removal, which is labor-intensive, expensive, and poor in cleaning effect. Generally, it can only reduce emissions by 40% to 50%. ; If the water-soaked excrement cleaning management mode of the leaking excrement floor is adopted, it can only reduce the discharge of fecal sewa...

[0002] The rapid development of the large-scale pig farming industry has solved the problem of ensuring the supply of pork non-staple food for urban and rural residents, but the discharge of feces and sewage from large-scale pig farms has also caused serious pollution to the rural environment

In order to solve the problem of fecal sewage discharge reduction in large-scale pig farms, the traditional cleaning methods for pig farms generally use manual manure removal, which is labor-intensive, expensive, and poor in cleaning effect. Generally, it can only reduce emissions by 40% to 50%. ; If the water-soaked excrement cleaning management mode of the leaking excrement floor is adopted, it can only reduce the discharge of fecal sewage, but cannot reduce the total amount of organic pollutants

To achieve discharge standards, it is necessary to extend the hydraulic retention time of sewage treatment, and it is necessary to increase investment in sewage treatment projects
