Abstract

The invention belongs to the technical field of biogas engineering, and mainly relates to an inclined stirring double-residue discharge biogas digester which comprises a reaction tank and an arc-shaped cover, wherein a gas outlet tube is arranged at the top of the arc-shaped cover; a stirring motor is fixedly mounted on the upper end surface of the arc-shaped cover; the motor shaft of the stirring motor is arranged towards the reaction tank in an inclined manner; a stirring shaft is connected with the lower end of the motor shaft; a base is fixedly arranged at the bottom of the stirring shaft; stirring blades are hinged at the periphery of the base in a hinged manner; steel chains are fixedly mounted between stirring blades which are distributed in symmetry about the center of the base; a feeding tube is arranged on a side wall of the reaction tank; a discharge tube is arranged on the side wall of the reaction tank; the discharge tube is connected with a residue discharge device; an inclined support plate is arranged at the bottom of the reaction tank; the lowermost end of the inclined support plate is arranged below the discharge tube. The inclined stirring double-residue discharge biogas digester is capable of turning over and crushing materials, uniformly mixing the materials and improving the fermentation efficiency, and is simple in structure, convenient to use and convenient in residue discharge.

Description

technical field [0001] The invention belongs to the technical field of biogas engineering, and mainly relates to a biogas digester with inclined stirring and double slag discharge. Background technique [0002] After years of development of biogas, people have already moved from the initial low-level functional requirements to a higher level. Especially in today's society that pays attention to improving the energy crisis and rural environmental problems, it becomes more and more important to promote and popularize biogas. However, traditional biogas digesters are expensive, occupy a large area, are cumbersome to use and maintain, and have low production efficiency; the slag discharge port is located at the bottom of the biogas digester, making slag discharge inconvenient. Contents of the invention [0003] In order to solve the above technical problems, the present invention provides an inclined stirring double slag discharge biogas digester. [0004] Technical scheme o...
