Biogas digester cleaning machine for biomass straw and human and animal excrement mixed fermentation preparation

Abstract

The invention relates to a biogas digester cleaning machine for biomass straw and human and animal excrement mixed fermentation preparation. The biogas digester cleaning machine consists of a base plate, travelling wheels and a scraping device. The travelling wheels are mounted at the lower end of the base plate, the scraping device is mounted at the upper end of the base plate, and the scraping device consists of lifting air cylinders, a lifting stand, a rotary mechanism, a mounting column, a stabilizing mechanism, scraping mechanisms, a No.1 collection mechanism and a No.2 collection mechanism. The stabilizing mechanism includes an annular sliding rail, rotary sliding tables, a traction electric push rod, a connecting ring, support rods, an extrusion plate and a rubber strip. Each scraping mechanism includes telescopic support plates, No.1 limit plates, No.2 limit plates, push air cylinders, auxiliary plates and scrapers. The biogas digester cleaning machine provided by the inventioncan solve the problems of large labor intensity, low work efficiency, poor reliability, large potential safety hazard and the like in existing biogas digester feed inlet residue cleaning process, canrealize the function of automatic cleaning of biogas digester feed inlet residue, and has the advantages of high work efficiency, high reliability, high work safety, etc.

Description

technical field [0001] The invention relates to the field of new energy and environmental protection equipment, in particular to a biogas tank cleaning machine prepared by mixed fermentation of biomass straw and human and animal manure. Background technique [0002] Straw biogas refers to a combustible gas produced by anaerobic fermentation of microorganisms under strict anaerobic environment and certain temperature, moisture, pH and other conditions using biogas equipment and using crop biomass straw as the main raw material. Biomass straw is mainly used as raw material for biogas fermentation, such as wheat, corn, peanut, soybean and other crop biomass straw. The straw biogas commonly used in rural areas is mainly prepared by mixed fermentation of biomass straw and human and animal manure. Comprehensive utilization of biogas digesters is an important way to change the rural environment. The construction of a biogas digester can be used for about 20 years. Comprehensive ut...
