Manual surface type biogas discharge pump

Abstract

The invention relates to a hand-operated ground type biogas discharging pump. The traditional hand-operated pump has problems of small application range, bulkiness, inconvenience for movement and poor blocking resistance and passing performance. The biomass discharging pump comprises an upper pump body (1); a liquid discharging pipe (2) is arranged at one side under the upper pump body; a cylinder sleeve (3) is connected under the upper pump body; a liquid inlet pipe is connected under the cylinder sleeve; the liquid inlet pipe is connected with a one-way valve (5); the liquid inlet pipe is connected with a liquid sucking pipe (6); the liquid sucking pipe is connected with a liquid sucking head (7) with the one-way valve; and the upper end part of the upper pump body is connected with a discharging device which is connected with a piston (14). The product is a hand-operated pump.

Description

Technical field: [0001] The invention relates to a manual surface biogas discharge pump. Background technique: [0002] Existing biogas digester discharge methods mainly include vacuum suction liquid filling trucks, electric submersible sewage pumps and piston pumps of various principles, manual submerged pumps and surface pumps, simple aspirators and other methods. Vacuum liquid suction vehicles have high pumping speed and good anti-clogging performance, but they are expensive to use, and some places are not easy to approach; vane electric submersible sewage pumps have high pumping speed, but the anti-clogging performance is often not as good as that of piston pumps, and the power supply voltage in remote areas is low. It often affects the performance of electric submersible sewage pumps. Most of the manual pumps are piston pumps, which have better anti-clogging performance, but not as high as the pumping speed of electric submersible sewage pumps; submerged manual pumps ha...

AI Technical Summary

Problems solved by technology

Vacuum liquid suction vehicles have high pumping speed and good anti-clogging performance, but they are expensive to use, and some places are not easy to approach; vane electric submersible sewage pumps have high pumping speed, but the anti-clogging performance is often not as good as that of piston pumps, and the power supply voltage in remote areas is low. It often affects the performance of electric submersible sewage pumps. Most of the manual pumps are piston pumps, which have better anti-clogging performance, but not as high as the pumping speed of electric submersible sewage pumps; submerged manual pumps have low requirements for pump manufacturing accuracy and suction. , but the body is long and inconvenient to move, and some pool types cannot be used; the manual ground pump is not limited by the pool type and is easy to move, but requires high manufacturing precision; limited to the environmental and economic conditions of each user, manual pumps are still widely used

However, the existing manual pumps still have the problems of small adaptability, bulkiness, inconvenient movement, anti-blocking and unsatisfactory passing performance.
