A biogas digester with high safety

Abstract

The invention provides a biogas digester with high safety, and belongs to the technical field of biogas. The biogas digester with the high safety comprises a biogas digester body and a digester lid which is fixedly arranged at the top of the biogas digester body, the digester lid is provided with an air outlet, the biogas digester body is vertically provided with a fermentation bucket, the digester lid is provided with a slag discharging opening opposite to the fermentation bucket in a penetrating mode, the digester lid is fixedly provided with a sealing plate which seals the upper end opening of the slag discharging opening in a detachable mode, the inner bottom wall of the biogas digester body is fixedly provided with a motor, the motor is connected with the bottom of the fermentation bucket through a lead screw-nut transmission mechanism so as to drive the fermentation bucket to abut against the digester lid or away from the digester lid, when the fermentation bucket abuts against the digester lid, the top wall of the fermentation bucket abuts against the inner top wall of the digester lid so as to form sealing, the biogas digester body is vertically and fixedly provided with a straight pipe-shaped connecting pipe, the upper end of the connecting pipe penetrates through the digester lid, the lower end opening of the connecting pipe is internally fixedly provided with a cylindrical drain plug, and a power wire of the motor penetrates through the drain plug and the upper end opening of the connecting pipe in sequence. The biogas digester with the high safety has the advantages of being capable of lowering biogas waste in a deslagging process.

Description

technical field

[0001] The invention belongs to the technical field of biogas, and relates to a biogas digester, in particular to a biogas digester with high safety. Background technique

[0002] Biogas can be used not only as energy for lighting, but also as gas energy for cooking. Since the main raw material for generating biogas comes from crops, it can greatly reduce the consumption of forest resources and coal-fired resources. Therefore, biogas is a popular energy-saving technology that has been popularized and applied in recent years and is widely used in rural areas.

[0003] Existing biogas digesters use traditional building materials such as bricks, sand, lime, and cement. Although the method of building a biogas digester is relatively simple, the daily maintenance requirements after completion are very high, and there are many faults during use, for example, leakage Gas is the most common fault in the use of biogas digesters. Often due to poor sealing between the ...
