Sewage treatment water pump with reminding function

Abstract

The invention discloses a sewage treatment water pump with a reminding function, and belongs to the technical field of sewage treatment. During sewage treatment, resistance is generated after permeability of a main filter element is gradually reduced, and when the resistance reaches a certain value, water is sucked into a water pump through an auxiliary filter cylinder and then discharged. Therefore, the problem that the drainage flow of the water pump is small due to poor permeability of the main filter element is solved, and the sewage treatment efficiency is guaranteed. A hook block rod is driven by an ejector rod to enable two triangular blocks to be in contact, so that a counterweight ring block falls off without being supported by the hook block rod, and a plurality of dialing pieces can be dialed by a dialing block to give out a reminding sound to inform people to replace the main filter element. Meanwhile, an auxiliary filter element ascends under the suction force of the water pump, a jacking rod jacks a colored rod out of a prompting barrel, so that people are informed that the auxiliary filter element is in use, and people can conveniently and quickly know the pipeline where water is located and further know the filter element needing to be replaced.

Description

technical field [0001] The invention relates to the technical field of sewage treatment, in particular to a water pump for sewage treatment with a reminder function. Background technique [0002] In the process of sewage treatment, it is necessary to use a water pump to pump out the sewage for further treatment. Since the sewage contains a large amount of impurities, in order to avoid damage to the water pump during the use of the water pump, a filter element is usually installed at the water inlet pipe of the water pump. This acts as a filter for the water. [0003] However, with the passage of time, the impurities in the sewage filtered by the filter element will also increase, resulting in a gradual decrease in the permeability of the filter element, causing the drainage flow of the pump to become smaller. Once it cannot be treated in time, the operation of the pump body will be aggravated. The burden affects the service life of the pump body and reduces the sewage treat...
