A submersible sewage pump for sewage treatment

Abstract

The invention relates to the technical field of sewage treatment, and discloses a submersible sewage pump for sewage treatment, which includes a water outlet pipe. When the water outlet pipe drains water, the incompletely broken large particles fall along the first filter screen to the second filter screen. At this time, part of the sewage discharged from the outlet pipe will enter the horizontal groove through the vertical groove, and the impact force of the sewage itself pushes the large particles to move inward. , the setting of the conveying wheel can make the movement of large particles more stable. The knife is located on the top of the large particles, which can evenly draw knife marks on the outer wall of the large particles, which is convenient for secondary crushing. The outlet pipe Part of the discharged sewage enters the recoil pipe through the vertical groove. Under the action of the flushing gun, the sewage water flow becomes thinner and the impact force becomes stronger, which can effectively flush the dirt at the bottom of the pump and achieve self-flushing. effect, preventing the accumulation of dirt.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a submersible sewage pump for sewage treatment. Background technique [0002] As the key equipment for environmental protection and sewage treatment, submersible sewage pump plays a very important role in municipal engineering, industry and water conservancy construction and other industries. The submersible sewage pump is generally installed at the bottom of the water to discharge the sewage in the sewage pool. With the continuous influx of sewage, the sewage will accumulate more and more at the bottom of the pump, especially when the sewage is discharged again after a period of shutdown, part of the sewage It may have dried up, and the suction of the pump alone may not be able to discharge the sludge. It needs to be washed and diluted first, so as not to affect the normal operation of the pump, but this will undoubtedly consume a lot of time and energy. processing eff...
