Problems solved by technology

[0006] In order to solve the above technical problems, the present invention provides a scraper mechanism for sewage treatment pools, to solve the problem that most of the existing mud scrapers are designed for scraping sludge and impurities at the bottom of the pool, and none of the devices can Thoroughly and effectively scrape off the sludge and impurities on the pool wall. At present, the blades of the mud scraper are generally arranged perpendicular to the pool wall or the bottom of the pool. When encountering hard obstacles, the blades and base are easy to collapse. Causes damage to the device, requires frequent maintenance, increases the cost of use, and causes inconvenience during use

Abstract

Relating to the technical field of wall scraping devices, the invention discloses a wall scraping mechanism for a sewage treatment tank, and solves the problems that the existing sludge scraper cannotscrape sludge and impurities on the tank wall and blades are easily ruined when encountering a hard obstacle. The wall scraping mechanism for a sewage treatment tank comprises scrapers, the scrapersare inserted into scraper holders in an interference fit manner, and the scraper holders are movably connected in a connecting sheet of a support rod body. The device employs the mode of clinging thearc-shaped scraper bodies and the scraper holders to the tank wall to scrape mud, and solves the problem that no device can scrape sludge and impurities on the tank wall at present, when the scraper bodies of the scraper holders in the device touch a hard obstacle and cannot move forwards, limiting blocks pull the scraper bodies to rise along the rotating shafts of fixed-axis rotating blocks, andafter crossing the obstacle, the scraper bodies reset again under the action of reset springs to perform sludge scraping treatment on the tank wall, thus protecting the scraper bodies from being ruined by the hard obstacle.

Description

technical field [0001] The invention belongs to the technical field of scraping devices, and more specifically relates to a scraping mechanism for sewage treatment pools. Background technique [0002] Sewage treatment is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse. Sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical care, catering, etc., and it is also increasingly entering the daily life of ordinary people. Usually, people will discharge sewage into sewage The treatment pool carries out sedimentation, filtration and purification of sewage. [0003] For example, the application number is: in the patent of CN201821195020.9, a central drive mud scraper is disclosed. The utility model provides a central drive mud scraper which is compact in structure, not easy to be blocked, and i...
