Fermentation device for organic fertilizer

Abstract

The invention discloses a fermentation device for an organic fertilizer. The device comprises an outer shell and an inner liner which are coaxially arranged, wherein an annular cavity is arranged between the outer shell and the inner liner; a steam heating coil is annularly distributed in the annular cavity; an air inlet and an air outlet of the steam heating coil are both formed on the outer shell; a stirring shaft is arranged in the inner liner; stirring blade sets are arranged on the stirring shaft at intervals; the upper end of the stirring shaft extends out of the outer shell and is in rotating fit with the outer shell; a stirring motor used for driving the stirring shaft to rotate is arranged at the top of the outer shell; a feeding port which is communicated with the inner liner is also formed at the top end of the outer shell; a discharging port is formed at the lower end of the inner liner; a methane draining pipe for draining methane is arranged on the upper part of the inner liner; a methane storage tank is connected with the methane draining pipe; a control valve is arranged on the methane draining pipe; a pressure sensor is arranged in the inner liner.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, in particular to an organic fertilizer fermentation equipment. Background technique [0002] Large-scale farming has become the main mode of production in my country's rural farming industry. It has the advantages of large breeding scale and large output, but at the same time, it produces a large amount of livestock and poultry manure, which has become an important source of environmental pollution. The moisture content of livestock and poultry manure is high. , not easy to store and transport, high processing cost and poor benefit. Fermenting livestock and poultry manure to reduce moisture and improve fertilizer efficiency is an effective way to reduce processing costs and reduce environmental pollution. Currently, the existing fermentation methods of livestock and poultry manure mainly use tanks Type fermentation device, the general fermentation period is as long as 15-20 days, the...
