Device for producing biogas by straw fermentation

Abstract

A device for producing biogas by straw fermentation comprises a barrel, a motor and an electric cylinder, wherein the side upper part of the barrel communicates with an exhaust pipe, the electric cylinder is mounted at the upper part of the barrel, a connecting rod is mounted at an output end of the electric cylinder, barbs penetrating through the upper wall of the barrel are uniformly mounted onthe connecting rod at equal intervals, the side part of the barrel communicates with a feeding pipe, a crushing bin is mounted at the feeding end of the feeding pipe, the motor is mounted on the sideof the crushing bin, a blade is mounted at the output end of the motor, a water pump is mounted on the side of the barrel, a spray head is mounted at the water outlet end of the water pump, and the spray head is mounted in the feeding pipe. the motor drives the blade to rotate to crush straw, the crushed straw directly enters the barrel, the electric cylinder drives the connecting rod and the barbs to realize disturbance, and environmental pollution is avoided, and the overflow of biogas is effectively increased.

Description

technical field [0001] The invention relates to the technical field of straw fermentation, in particular to a straw fermentation biogas device. Background technique [0002] Straw refers to the remaining stems and leaves after mature threshing of gramineous crops such as rice, wheat, and corn. Due to the popularization of coal, electricity, and natural gas, and the abundance of various industrial products, the demand for straw in rural areas has decreased, and the processing of a large amount of straw has become a As a serious social problem, the way of straw fermentation to produce biogas has been more and more widely used as a way of effective utilization of straw. [0003] However, the existing fermentation device is to add the crushed straw to the biogas tank for fermentation. The crushed straw is easy to generate dust outside, and the dust pollutes the external environment during the transfer process of the crushed dust. On the other hand, the straw is in the fermentati...

Problems solved by technology

[0003] However, the existing fermentation device is to add the crushed straw to the biogas tank for fermentation. The crushed straw is easy to generate dust outside, and the dust pollutes the external environment during the transfer process of the crushed dust. On the other hand, the straw is in the fermentation process Among them, due to its small bulk density, it is fluffy in the fermentation tank, which hinders the overflow of the generated biogas and is not conducive to the utilization of biogas
