High-concentration anaerobic fermentation equipment

Abstract

The invention discloses high-concentration anaerobic fermentation equipment, belongs to the field of biogas fermentation devices, and solves the problem that the cost is increased due to the fact thata stirring device is needed for fully mixing a solid material with biogas slurry in the prior art. The technical scheme for solving the problem is mainly as follows: a rotary conveying belt comprisesa first part, a second part, a third part and a fourth part; the first part extends downwards from the lower portion of a hopper to the position below the liquid level of a liquid storage tank; the second part extends upwards from the bottom of the first part to the position below a porous cover plate, and is higher than the liquid level of the liquid storage tank; the third part extends downwards from the top of the second part to the position below the liquid level of the liquid storage tank; the fourth part upwards extends out of the liquid level of the liquid storage tank from the bottomof the third part, and extends to the position above a biogas residue collection bin; a material pressing flange, which tilts upwards, is arranged at the outer side of a fermentation container; and afeeding channel is formed between the material pressing flange and the first part of the rotary conveying belt. The high-concentration anaerobic fermentation equipment in the invention is mainly usedfor fully mixing solid materials and biogas slurry in the conveying process; and automatic discharging is achieved.

Description

technical field [0001] The invention relates to a high-concentration anaerobic fermentation equipment. Background technique [0002] Some existing anaerobic fermentation equipment, such as the CN201933082U utility model patent, discloses an anaerobic fermentation device for direct biogasification of straw. Solid materials such as straw are sent into the fermentation chamber, and a stirring device is generally required to stir the solid material and biogas slurry. Mix well, add cost. Moreover, in the above-mentioned utility model patent, the biogas residue needs to be hoisted out by a leaking car for discharging, which is inconvenient to operate. Contents of the invention [0003] The purpose of the present invention is to provide a high-concentration anaerobic fermentation equipment, cancel the stirring device, allow the solid material and biogas slurry to be fully mixed during the transportation process, and realize automatic discharge. [0004] In order to achieve the ...
