A new type of biogas digester slag pumping device

Abstract

The invention discloses a novel biogas digester residue pumping device, which comprises a water discharging pipe, a crusher, a residue pumping pipe, a residue pump, a water tank, a water valve, an exhaust pipe, an exhaust valve, a controller, a ceiling, a material inlet and a biogas digester main body, wherein the ceiling is arranged at the upper end of the biogas digester main body; the exhaust pipe is arranged on the ceiling; the exhaust pipe is provided with the exhaust valve; the material inlet is formed in one side of the biogas digester main body; the material inlet is formed in middle of the sidewall; the crusher is arranged at the bottom of the other side of the biogas digester main body; the crusher is connected to the residue pumping pipe; the residue pumping pipe is connected on the residue pump on the ground; the water discharging pipe is arranged above the crusher; and the water discharging pipe is connected to the water tank on the ground. The biogas digester residue pumping device disclosed by the invention has the beneficial effects that by arranging the crusher and the water discharging pipe at the front end of the residue pump, a residue pumping effect is enhanced, and an original residue pumping device is greatly optimized, so that people's demand on conveniently removing residues of a biogas digester can be satisfied.

Description

technical field [0001] The invention relates to the field of energy, in particular to a device for extracting slag from a biogas pit. Background technique [0002] The biogas digester is the main place to generate biogas, and it has been widely used in many rural areas of our country. When generating biogas, the biogas residue and biogas slurry in the biogas digester are good organic fertilizers. After the biogas is used up, new reactants need to be added. It is necessary to discharge the remaining biogas slurry and biogas residue, but most of the biogas digesters in the existing rural areas are buried deep underground, and the volume of the biogas digesters is relatively large. The cost is also high. Therefore, a set of convenient and efficient biogas tank slag extraction device with high salvage efficiency is needed. Contents of the invention [0003] The object of the present invention is to provide a biogas tank slag extraction device to solve the problems raised in ...
