AI Technical Summary

Technical Problem

In existing technologies, when treating wastewater from double-layer limiting plastic pin cleaning, plastic fragments become statically charged when colliding with each other in the turbulent water flow and rubbing against the wall. Opposite charges attract each other, causing the filter layer to become clogged, which in turn damages the filtration effect and leads to uncontrolled effluent quality.

Method used

The double-layer limiting plastic pin cleaning wastewater treatment fixture uses the linkage of the starting component, the filtration component and the central component. The screw block, positioning sleeve, connecting rod and moving block drive the turntable and scraper to reciprocate along the irregular arc surface. Combined with the cooperation of the filter plate and the cleaning frame, it can scrape and vibrate to clean plastic impurities, and avoid impurities from getting stuck and blocking the filter holes.

Benefits of technology

It effectively avoids filter bed clogging, maintains stable filter surface flow efficiency, improves solid-liquid separation rate, enhances effluent quality, simplifies maintenance procedures, and reduces cleaning workload.

Abstract

This invention relates to the field of wastewater treatment technology, and in particular to a double-layer limiting plastic pin cleaning wastewater treatment tool, including a wastewater cylinder and a starting component for treating double-layer limiting plastic pin cleaning wastewater on a support block. Through the arrangement of the starting component, filtration component, and concentrating component, the bearing bar and bearing rod drive the scraper at the bottom of the lifting column to reciprocate and scrape along the curved surface of the irregular platform. The bearing plate continuously impacts and touches the inner wall of the cylinder, generating high-frequency vibration. The scraping and vibration work together to clean the plastic impurities adhering to the surface and pores of the irregular platform mesh in real time. Addressing the electrostatic adsorption effect generated by the friction between the release agent film on the surface of the plastic debris and the water flow, this dual action prevents plastic impurities from embedding and jamming the filter pores, avoiding the core problems of easy filter layer clogging, continuous decline in flow efficiency, and excessive fluctuations in suspended solids in the effluent. It maintains a stable effective flow area on the irregular platform filter surface and reduces the frequency of filter layer disassembly and replacement.
