Production line and production method for preparing organic fertilizer from pig manure through fermentation

Abstract

The invention provides a production line and a production method for preparing an organic fertilizer from pig manure through fermentation. The biological organic fertilizer can be prepared from the pig manure. The production line for preparing the organic fertilizer from pig manure through fermentation comprises pretreatment equipment, fermentation equipment and pelleting equipment, wherein the pretreatment equipment comprises a solid-liquid separation machine, a straw crushing machine and a mixing machine; the discharge hole of the solid-liquid separation machine and the discharge hole of the straw crushing machine are connected with the feeding hole of the mixing machine; the fermentation equipment comprises a fermentation tank and a turning machine; the fermentation tank is connected with the discharge hole of the mixing machine; a guide track is arranged on the inner side of the fermentation tank; the turning machine can move back and forth along the guide track; the pelleting equipment comprises a half-wet material crushing machine, a vibration screen, a disc pelleting machine, a low-temperature drying-cooling integral machine, a cylinder screening machine and a quantitative granule packaging machine which are arranged in sequence.

Description

technical field [0001] The invention relates to an organic fertilizer production line, in particular to an organic fertilizer production line and production method prepared by fermenting pig manure, and belongs to the technical field of agricultural equipment. Background technique [0002] With the rapid development of animal husbandry, more and more attention has been paid to the harmless disposal of pig manure in pig farms. This is because if pig manure is allowed to accumulate randomly, it will cause serious pollution to the environment and seriously threaten human beings. health. Pig manure from existing small and medium-sized pig farms is generally returned directly to the field, treated by biogas treatment or fertilizer treatment. Direct return to the field requires land consumption, biogas treatment requires large investment, poor effect, high operating costs, and the fertilizer treatment cycle is long and automated. The low level and poor quality of finished organic...

AI Technical Summary

Problems solved by technology

In the existing small and medium-sized pig farms, pig manure is generally returned directly to the field, treated by biogas treatment or fertilizer treatment. Direct return to the field requires land consumption, and the treatment of biogas treatment requires large investment, poor effect, and high operating costs. The fertilizer treatment cycle is long and automated. The low level and poor quality of the finished organic fertilizer have seriously restricted the healthy and rapid development of the animal husbandry industry.
