AI Technical Summary

Technical Problem

Sludge may harden at the bottom of the sedimentation tank or float to the surface due to gas produced by anaerobic fermentation, requiring the bottom of the sedimentation tank to be emptied and cleaned, which is a cumbersome and inconvenient operation.

Method used

A wastewater purification sedimentation tank was designed, which includes a tilting mechanism, a scraping mechanism, and a sludge discharge mechanism. By tilting the sedimentation plate, scraping off the sludge, and circulating the wastewater using a circulating pump and a filter screen, the sludge is discharged by the sludge discharge mechanism, simplifying the cleaning process.

Benefits of technology

It enables convenient cleaning of sludge at the bottom of sedimentation tanks, simplifies the operation process, and avoids cumbersome emptying operations.

Abstract

This utility model discloses a wastewater purification sedimentation tank, relating to the field of wastewater purification technology. It includes a sedimentation tank body, a sedimentation plate rotatably connected to the center of the inner cavity of the sedimentation tank body, a tilting mechanism on the outer side of the sedimentation tank body, a scraping mechanism located below the sedimentation plate on the sedimentation tank body, support legs fixedly installed at the four corners of the bottom of the sedimentation tank body, and a filter screen installed at the bottom of the inner cavity of the sedimentation tank body. This utility model uses the tilting mechanism to drive the sedimentation plate to rotate 180 degrees, so that the hardened sludge faces downwards. Then, the scraping mechanism scrapes and separates the sludge from the sedimentation plate. A circulation pump recirculates the wastewater below the sedimentation plate through a circulation pipe to the area above the sedimentation plate in the sedimentation tank body, where the sludge is intercepted by the filter screen. Finally, a sludge discharge mechanism discharges the sludge from the sedimentation tank body. This method achieves the cleaning of the hardened sludge at the bottom of the sedimentation tank without the need for emptying the sedimentation tank, making the operation simple and convenient.
