Livestock and poultry manure fermentation system

Abstract

The invention discloses a livestock and poultry manure fermentation system. The system comprises a manure storage tank, a fermentation tank and a deodorization tank, a mixing chamber, a fermentation chamber and a fermentation seepage collection chamber are arranged in the fermentation tank, a feed hopper is arranged above the mixing chamber, a material guide auger is arranged in the mixing chamber, the top surface of the mixing chamber is provided with strain liquid spray heads, a mesh conveying belt is arranged in the fermentation seepage collection chamber, a fermentation seepage collectingarea is arranged below the mesh conveying belt, a cleaning unit, a drying layer and an ultraviolet lamp are sequentially arranged in the deodorization tank along the flowing direction of a gas, and achemical liquid is contained in the cleaning unit. A strain liquid is sprayed while materials are fed into the mixing chamber through the feeding hopper, the manure and the strain liquid are evenly mixed under the action of the material guide auger, and then enter the fermentation chamber, and odorous gas generated during fermentation in the fermentation tank is discharged into the deodorization tank, is sequentially washed with the chemical liquid, dried with the drying layer and irradiate-disinfected with the ultraviolet lamp, and finally is discharged. The system has the advantages of simple structure, close, compact and efficiently and stably operated links, good harmful gas deodorizing, purifying and disinfecting functions, and high practicability.

Description

Technical field [0001] The invention relates to the field of manure recovery and treatment, in particular to a livestock and poultry manure fermentation system. Background technique [0002] The traditional treatment of livestock and poultry manure is relatively random, and the treatment methods include stacking retting and burning, etc., which not only affect the environmental odor, but also require a lot of manpower and financial resources to process. [0003] In order to solve the above-mentioned problems, fermenting devices are currently used to carry out concentrated fermentation treatment of manure, which can effectively decompose and process manure while obtaining a large amount of organic fertilizer. However, the existing fecal fermentation device is not only complex in structure, low in work efficiency, but also simple in function. The feces will emit a large amount of harmful odor during the fermentation process, and the direct discharge will not only pollute the environm...
