Non-woven fabric dyeing sewage treatment equipment with multiple filtering function

By designing an upper rotating rod system that combines a buoyancy bladder and a sliding rail, the problem of liquid level fluctuation caused by the intermittent drainage in nonwoven fabric production was solved, achieving a stable cleaning effect for the slag scraper and improving the removal efficiency of scum and suspended solids.

AI Technical Summary

Technical Problem

The intermittent drainage during the nonwoven fabric production process causes frequent fluctuations in the flocculation tank level. Traditional fixed scum scrapers cannot effectively clean the floating scum, resulting in extremely low cleaning efficiency.

Method used

Design a sludge scraping assembly, including an upper rotating rod system that cooperates with a buoyancy bladder and a slide rail. The buoyancy bladder provides buoyancy so that the upper rotating rod rises and falls with the change of liquid level, ensuring that the liquid surface scraper is always suspended on the liquid surface. Through the dynamic cooperation of the transmission spline and the worm gear blade, a constant sludge pushing action is achieved.

Benefits of technology

It solves the problems of missed scraping and accidental scraping by the surface scraper when the liquid level changes, improves the capture rate of scum and suspended solids, and ensures cleaning efficiency.

Abstract

This invention discloses a wastewater treatment device for non-woven fabric dyeing with multiple filtration functions. The device includes a main body containing, in the order of water flow treatment, an equalization tank, a flocculation tank, a sedimentation tank, an anoxic tank, an aerobic biological treatment tank, a secondary sedimentation tank, and a clear water tank. The flocculation tank includes a sludge scraping assembly. The power source for the sludge scraping assembly includes a drive motor connected to an external power supply and a transmission gear set connected to the drive motor. The transmission gear set includes a main gear fixedly connected to the drive shaft of the drive motor and two auxiliary gears. The sludge scraping assembly designed in this invention, through the cooperation of a buoyancy bag and a sliding rail, allows the height of the upper rotating rod to change with the buoyancy feedback of the liquid surface, ensuring it remains suspended on the liquid surface. This maintains a constant relative distance between the scraper and the liquid surface, solving the problems of missed scraping and accidental scraping, ensuring a high capture rate of fiber debris and suspended oil on the liquid surface, and reducing their escape.
