Dry type sewage pump

Abstract

The invention discloses a dry type sewage pump which comprises a motor, a controller, a motor bracket, a shaft coupler, a bearing room, a supporting barrel body, a pump shaft, a bearing, a pump cover, a pump body, an impeller, water inlet tubes, a suction bell mouth, a stirrer, filters and a liquid level meter, wherein the motor for driving the sewage pump is a common dry type motor; the controller starts or stops the dry type sewage pump through a signal of the liquid level meter; the impeller is a double-suction impeller, so that circulating capacity of the sewage pump is improved; and the stirrer is used for uniformly mixing particulate matters in sewage with the sewage, so that a suction inlet of the dry type sewage pump is prevented from being blocked by sludge settling. The water inlet tubes are used as conveying channels at a sewage suction end, and also are used as supporting points to support the whole sewage pump; and the suction bell mouth realizes guide effect, so that the suction inlet of the impeller is prevented from turbulent flow.

Description

Technical field [0001] The invention relates to a dry sewage pump, in particular to a sewage pump used for sewage discharge in a pit pool of an enterprise under working conditions. Background technique [0002] According to the needs, the working condition companies have designed pit ponds for sewage collection, such as the sewage pit pond used to collect sewage after dust washing treatment in a steel plant. In order to prevent sewage from overflowing the sump, the sewage needs to be discharged irregularly in the pit pool to a certain depth. At present, most of the submersible sewage pumps are used for the discharge of sewage from the pit pool: on the one hand, the submersible sewage pump generally requires a fixed installation of the base frame, which is inconvenient to move; on the other hand, the start and stop of the submersible sewage pump requires manual operation and requires special personnel. [0003] In view of the above-mentioned problems, the water inlet pipe of the dr...
