Automatic film coating type aerobic fermentation device and using method thereof

Abstract

The invention provides an automatic film covering type aerobic fermentation device. The automatic film covering type aerobic fermentation device comprises a fermentation box, an aeration ventilation system, an automatic film covering system, an automatic film pressing device and a detection control system, wherein openings are formed in the top and one side of the fermentation box, and aeration pipelines are arranged at the bottom of the fermentation box; the automatic film covering system is composed of a reciprocating device, a film rolling / covering device, a guiding device, a detecting device and a film, and as the reciprocating device reciprocates on a steel rail, the film rolling / covering device automatically completes a top film rolling / covering process; the automatic film pressing device realizes automatic sealing of the film through a bracket, a speed reducing motor, a chain wheel, a chain, a transmission shaft, a steel wire rope wheel, a steel wire rope, a counterweight and aninductive switch; and the detection control system comprises an electric control cabinet, an oxygen sensor, a temperature and humidity sensor and a limit switch, the oxygen sensor and the temperatureand humidity sensor monitor a real-time state in the fermentation box, and the limit switch controls the start-stop position of reciprocating motion and the vertical position of automatic film pressing. The automatic film covering type aerobic fermentation device in the invention has the advantages of simplicity in operation, labor saving, high automation degree, wide application range, low investment and operation cost and the like.

Description

technical field [0001] The invention relates to the technical field of aerobic fermentation treatment of agricultural and animal husbandry organic waste, in particular to an automatic film-covered aerobic fermentation device. Background technique [0002] With the development of agricultural production and changes in rural fertilization habits, agricultural and animal husbandry organic wastes such as crop stalks and livestock manure have become an important source of pollution in the rural environment. For the treatment and utilization of agricultural and animal husbandry organic waste, domestic and foreign scholars have proposed a series of methods, among which aerobic composting fermentation is the most economical and feasible method. Organic waste from agriculture and animal husbandry is rich in organic matter and contains various plant nutrients such as nitrogen, phosphorus, potassium, trace elements and humus. After aerobic composting and fermentation, it can be used to...
