AI Technical Summary

Technical Problem

Larger impurities in existing wastewater can easily cause blockages if they directly enter the cavitation pump. The cavitation pump has a complex structure, high maintenance costs and inconvenience, and is prone to damage.

Method used

A rotary hydraulic cavitation pump treatment device was designed, comprising a pre-filter element and a drive assembly. Large impurities are separated by a crushing blade and filter plate in the filter box, and the filter plate is cleaned by a motor-driven transmission component and a bevel gear set. Combined with a multi-stage filter and a precipitator, multiple filtrations are performed to prevent impurities from entering the cavitation pump.

Benefits of technology

It effectively separates large impurities from wastewater, prevents cavitation pump blockage, reduces maintenance costs, simplifies maintenance processes, and extends equipment life.

Abstract

This utility model relates to the field of wastewater treatment technology, and in particular to a rotary hydraulic cavitation pump wastewater treatment device, including a treatment tank. A pre-filtration element is provided at the upper end of the treatment tank. The pre-filtration element includes a filter box fixedly mounted at the upper end of the treatment tank. Two sets of symmetrical connecting plates are inserted into the inner wall of the filter box. When the motor is started, wastewater is poured into the filter box through the inlet at the upper end. The motor drives a first rotating rod to rotate, which in turn drives a crushing blade to rotate via a first transmission component. The crushing blade cuts the wastewater entering the inlet, breaking larger impurities into smaller ones. The wastewater then passes through two sets of filter plates, with the filter holes gradually decreasing in size from top to bottom. This allows for the filtration of impurities of different sizes, preventing larger impurities from entering the cavitation pump body and causing blockage and damage.
