Turning plate type monorail mud scraper

Abstract

The invention relates to a turning plate type monorail mud scraper, which comprises a driving device, a traction chain, a trolley scraping plate combination, turnabout gear trains, a rail assembly anda tensioning device, wherein the driving device is arranged at the top of a water inlet end of a sedimentation tank, the turnabout gear trains are arranged at the two ends of the sedimentation tank,the traction chain is sleeved on the driving device and the turnabout gear trains, the rail assembly is arranged in the middle of the bottom of the sedimentation tank along the length direction of thetank, the trolley scraping plate combination is arranged on the rail assembly, the tensioning device is composed of a manual tensioning device and an automatic tensioning device, and the automatic tensioning device is composed of a pendulum bob tensioning device and a large-span suspension structure. According to the invention, the problems that according to an existing turning plate type monorail mud scraper, the technological requirement for partial-stroke and full-stroke combined mud scraping cannot be met, a reversing and tensioning mechanism is complex, the occupied ground position is large, installation and maintenance are complex, a chain is prone to abrasion, and the manufacturing cost of the whole scraper is high are solved.

Description

Technical field[0001]The invention relates to the field of water treatment equipment, in particular to a turning plate type monorail mud scraper.Background technique[0002]At present, the working principle of the existing monorail scraper is driven by the driving device, and the drag chain and the drag scraping trolley run intermittently or continuously at the bottom of the pool, and the scraper on the mud scraping trolley continuously moves The silt and sediment at the bottom of the pool are scraped into the mud trough, and then discharged by the mud pipe. When the scraper is vertically erected and moves toward the mud pit, it is called the mud scraping process. On the contrary, when the scraper moves horizontally in the opposite direction of the mud pit, it is called the return process; when the trolley reaches the designated position, a scraping process is completed. After the mud process, the touch plate on the mud scraping trolley touches the limit rod extending from the top of ...
