Anti-blocking water intake pump used at construction site

Abstract

The invention discloses an anti-blocking construction site water intake pump, which comprises a water pump, and a decontamination device is installed at the front end of the water inlet of the water pump; the decontamination device includes a coarse filter net, a fine filter net, an electromagnetic valve and a pressure sensor; Installed above the support frame, the coarse filter is installed inside the water inlet of the decontamination device, the first water guide is located under the coarse filter; the fine filter is installed on the side of the coarse filter away from the water inlet of the decontamination device, The second water guide sheet is installed under the fine filter screen; the decontamination device also includes a first motor arranged above the drain outlet of the decontamination device, and the rotating shaft of the first motor passes through the center of the fine filter screen; the pressure sensor is installed On the shell inner wall below the drain port of the decontamination device, the discharge port of the decontamination device is connected with the water inlet of the water pump. The invention adopts double-stage filtration to separate impurities according to categories, remove impurities thoroughly, and prevent water flow from being blocked by impurities; effectively protect the impeller of the water pump, increase its service life, and improve work efficiency.

Description

technical field [0001] The invention relates to a water pump, in particular to an anti-blocking construction site water intake pump. Background technique [0002] With the acceleration of the urban construction process, many high-rise buildings have sprung up, so construction sites can be seen everywhere. At present, construction work is inseparable from water due to the use of many building materials, so the amount of water taken is large. Considering the existing cost and convenience, most of them are taken from river water or groundwater. There are impurities such as sand and gravel in the pumped water, which not only damages the impeller of the pump, reduces the life of the pump, but also easily blocks and reduces the water flow. Contents of the invention [0003] In order to solve the shortcomings of the above-mentioned technologies, the present invention provides an anti-blocking construction site water intake pump. [0004] In order to solve the above technical pr...
