Problems solved by technology

Therefore, during the feeding process, after the feeding pump stops working, the material in the feeding pipe is easy to flow back and impact the feeding pump due to the pressure difference, causing damage to it and affecting the feeding of the system.

Embodiment Construction

[0014] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0015] Such as figure 1 Shown: a feeding system for a straw biogas fermenter, including a fermenter 1, a feed pipe 2, a feed pump 3, a U-shaped pipe 4 and a feed tank 5, the top of the fermenter 1 is connected to a feed Pipe 2, feeding pipe 2 is fixed along the side of fermenter 1 and extends downwards to the ground, one end of feeding pipe 2 extends into the bottom of feeding tank 5 through U-shaped pipe 4 and feeding pump 3 fixed in feeding tank 5 Connected, the height of the top of the U-shaped pipe 4 is not lower than the position of the feed pipe 21 of the horizontal section on the ground.

[0016] The above-mentioned feeding system uses the feeding pump to input the materials in the feeding tank into the fermenter through the U-shaped pipe and the feeding pipe. When the feeding pump stops working, the fluid in the vertical section of t...

Abstract

The invention relates to a feeding system of a straw biogas fermentation tank, and belongs to the technical field of straw biogas fermentation. The feeding system comprises a fermentation tank, a feeding pipe, a feeding pump, a U-shaped pipe and a feeding pool, wherein the top of the fermentation tank is connected with the feeding pipe; the feeding pipe is fixed along the side face of the fermentation tank and extends downwards to the ground; one end of the feeding pipe extends into the bottom of the feeding pool and is connected with a feeding pump fixed in the feeding pool through the U-shaped pipe; and the height of the top end of the U-shaped pipe is not lower than the position of the feeding pipe of a horizontal section on the ground. The U-shaped pipe is arranged between the feedingpipe and the feeding pump in the feeding pool, so that the water sealing effect can be achieved, and the situation that after the feeding pump stops working, a fluid in the feeding pipe of a verticalsection flows back to generate impact due to pressure difference, and consequently the pump is damaged is avoided.

Description

technical field [0001] The invention relates to the technical field of straw biogas fermentation, in particular to a feeding system for a straw biogas fermentation tank. Background technique [0002] Straw biogas refers to a combustible gas produced by anaerobic fermentation of microorganisms under strict anaerobic environment and certain temperature, moisture, pH and other conditions using biogas equipment and using crop straw as the main raw material. [0003] The general straw biogas fermentation system is to push the crushed straw material into the feeding tank, add water and inoculum and other ingredients to stir and mix evenly, and then the mixed material is input into the fermentation tank through the pipeline by the feeding pump for fermentation to produce biogas. Since the height of the fermenter is generally very high, the feed inlet is basically located on the top of the fermenter, and there will be a large height difference between the feed tank and the feed inl...
