AI Technical Summary

Technical Problem

Traditional wastewater treatment filtration devices have low filtration accuracy, are prone to clogging, waste water resources, and lack automated control, making it difficult to meet the needs of modern wastewater treatment for high efficiency, energy saving, and automation.

Method used

A rotary drive assembly is used to drive the drum screen for wastewater filtration. Combined with a circulating flushing assembly and a circulating water tank, two-stage filtration and automatic dirt removal are achieved. The drum screen is flushed with a water spray gun, and the dirt flows back to the circulating water tank for further treatment, thus avoiding filter clogging.

Benefits of technology

It achieves efficient wastewater treatment, avoids filter clogging, improves filtration efficiency and equipment stability, reduces operating costs, and enables wastewater recycling.

Abstract

This utility model relates to the field of wastewater treatment technology, specifically a filtration device for wastewater treatment. Through the rotation of a drum screen, combined with a filter screen, solid-liquid separation and fine filtration of wastewater are achieved. During rotation, the drum screen quickly separates large particulate impurities from the wastewater, while the subsequent filter screen performs secondary fine filtration, effectively intercepting residual pollutants and significantly improving the wastewater purification level. Simultaneously, a circulating flushing component plays a crucial role; a water pump drives a spray gun to perform high-pressure flushing of the drum screen, promptly removing dirt adhering to its surface and preventing the filter screen from clogging due to impurity accumulation. The flushed dirt flows back to the circulating water tank via a fan-shaped collection trough for further treatment. This integrated design ensures stable and continuous operation of the equipment while significantly improving filtration efficiency and equipment lifespan, effectively meeting the stringent requirements of modern wastewater treatment for high efficiency, energy saving, and environmental protection.
