Abstract

The invention belongs to the field of mud scrapers, in particular to an underwater walking type sludge scraper for sewage treatment settling tanks. Aiming at the problem of inconvenient cleaning of the dirt on the inner wall of the existing sewage treatment settling tanks, the following scheme is proposed, which includes a top plate , motion mechanism, limiting plate, bottom plate, mobile platform and scraper, the middle part of the side wall of the limiting plate is embedded with a vertical rack, the bottom of the limiting plate is set with a bottom plate slidingly connected with it, and the top end of the bottom plate The connecting plate is fixed, the top of the mobile platform is fixed with a gear that meshes with the rack, the top of the mobile platform is slidably connected with a connecting block that is adapted to the connecting plate, and the side wall at the end of the mobile platform away from the connecting block and the scraper are connected with a metal The metal bellows is provided with a bottom blade and a side blade on the side wall of the scraper away from the moving platform. The invention can comprehensively clean the internal pollutants of the sewage treatment settling tank, is clean and efficient, and prolongs the service life of the sewage treatment settling tank.

Description

technical field [0001] The invention relates to the field of mud scrapers, in particular to an underwater walking type mud scraper for a settlement tank for sewage treatment. Background technique [0002] In sewage treatment plants, workers usually use sedimentation tanks to carry out flocculation and sedimentation treatment of sewage. After flocculation, solid pollutants settle to the bottom of the tank, and then work through the central rotating mud scraper. The peripheral sludge at the conical bottom is continuously sent to the center of the bottom for easy sludge discharge. [0003] The following problems occurred during the above process: 1. There is a gap between the scraper and the bottom of the pool, and hard stones are easily stuck between the scraper and the bottom of the pool. If the driving force of the scraper is not enough, it is easy to cause mud scraping In severe cases, the mud scraper does not move, and the driving motor of the mud scraper is easily short-...
