Embodiment Construction

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0038] figure 1 It is a schematic diagram of the structure of the dry sewage pump of the present invention, such as figure 1 As shown, the dry sewage pump includes a motor 2, a controller 3, a motor bracket 4, a coupling 5, a bearing chamber 6, a support cylinder 7, a pump shaft 8, a bearing 9, a pump cover 10, a pump body 11, and an impeller 12. , Suction bell 13, agitator 14, water inlet pipe 15, filter 16, water outlet pipe 17, lower liquid level gauge 18, upper liquid level gauge 19 and signal line 20.

[0039] The dry sewage pump is driven by the motor 2 through the coupling 5 and the pump shaft 8 to rotate the impeller 12, sucking sewage into the pump body 11 from the suction bell 13 and the inlet pipe 15. The impeller 12 transfers kinetic energy to the sewage, so that the pot...

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...
