Multi-level developing and utilizing system for plant straws

Abstract

The invention belongs to the technical field of straw fermentation equipment, and specifically relates to a multi-level developing and utilizing system for plant straws. The system comprises a charging module, a fermentation module, an overturning module, a fertilizer producing module, a discharge hopper and a conveyor belt, wherein the charging module is used for realizing smashing of the strawsand conveying the smashed straws into the fermentation module; the fermentation module is used for realizing the biogas fermentation of the straws; the fertilizer producing module is used for producing the straw residue through biogas fermentation into a fertilizer; the overturning module is used for conveying the straws to be fermented to the fermentation module and conveying the residue generated after straw fermentation to the fertilizer producing module; the discharge hopper is used for storing the granular fertilizer formed through the fertilizer producing module, and a valve is arrangedat the bottom of the discharge hopper; the conveyor belt is positioned below the discharge hopper, and the conveyor belt is used for conveying the fertilizer inside the discharge hopper. According tothe system, the straws can be fermented to produce biogas, and the biogas residue is produced into the fertilizer, so that multi-level utilization of the straws is realized, and the utilization rate of the straws is improved.

Description

technical field [0001] The invention belongs to the technical field of straw fermentation equipment, in particular to a multi-level development and utilization system of plant straws. Background technique [0002] At present, in many rural areas, crop stalks are often burned as waste, which not only causes serious waste, but also pollutes the environment. For this reason, effective utilization of straw resources has become an important issue at present. Among them, the use of straw fermentation to produce biogas and fertilizer are two important aspects of straw utilization. However, most of the current fermentation equipment is used to produce biogas or fertilizer, and there are few equipment that combine the two functions, resulting in waste of resources. At the same time, there is another important problem. The biogas residue discharge truck used in the traditional livestock and poultry manure biogas digester is a powerful suction type. If it is used for removing slag in ...
