Vertical organic fertilizer fermentation equipment

Abstract

The invention discloses vertical organic fertilizer fermentation equipment, comprising a shell and a inner container which are arranged coaxially, wherein an annular cavity is arranged between the shell and the inner container; a steam heating coil pipe is annularly arranged in uniform distribution in the annular cavity, and a steam inlet and a steam outlet of the steam heating coil pipe are formed in the shell; a stirring shaft is arranged in the inner container, and a stirring blade is arranged on the stirring shaft and is a helical blade for driving materials to move upwards; the upper end of the stirring shaft extends out of the shell and is in rotary matching with the shell; a stirring motor for driving the stirring shaft to rotate is arranged at the top of the shell; a feed hole communicated with the inner container is formed in the top end of the shell, and a discharge hole is formed in the lower end of the inner container; a biogas discharge pipe for discharging biogas is also arranged at the upper part of the inner container, a biogas storage tank is connected with the biogas discharge pipe, and a control valve is arranged on the biogas discharge pipe; and a pressure sensor is also arranged in the inner container.

Description

technical field [0001] The invention belongs to the technical field of fermentation equipment, in particular to a vertical 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 d...

[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, poor benefit, fermenting livestock and poultry manure, reducing water content, and improving fertilizer efficiency is an effective way to reduce processing costs and reduce environmental pollution. Currently, the existing livestock and poultry manure fermentation methods mainly use tanks Type fermentation device, the general fermentation period is as long as 15-20 days, the processing capacity is small, the space utilization rate of the production site is low, the floor area is large, and the production efficiency is low. Because there is no airtightness, the odor emitted will cause secondary pollution to the environment. It cannot meet the requirements of large-scale farms for handling livestock and poultry manure
