A sludge removal device for sewage treatment

Abstract

This utility model discloses a sludge removal device for wastewater treatment, mainly relating to the field of wastewater treatment. It includes a drive unit configured to output a horizontal reciprocating stroke; a sludge removal frame connected to the drive unit and obtaining the horizontal reciprocating stroke based on the drive unit, comprising multiple sludge removal units sequentially and fixedly connected along the reciprocating stroke direction. Each sludge removal unit includes a horizontal axis extending horizontally perpendicular to the reciprocating stroke direction. A scraper is provided above the horizontal axis, the scraper being inclined. A rotating sleeve hinged to the horizontal axis is provided near the top side of the scraper's bottom surface. A resistance plate at a 90-100 degree angle to the top side of the scraper is connected to the scraper. A limiting rod is provided parallel to the horizontal axis on one side, located between the rotating sleeve and the resistance plate, and the limiting rod is higher than the horizontal axis. The advantages of this utility model are: it can reciprocate and push sludge in a directional manner, and has a simple structure, modular and lightweight installation, easy maintenance, and reduced maintenance costs.
