The ZBGN series scraper is used in circular sedimentation tanks of sewage treatment plants to scrape and collect sludge settled at the bottom of the tank into a mud pit at the bottom of the tank, and skim the floating slag on the surface of the tank towards the slag hopper for further treatment.
The ZBGN series scraper, as shown in Figures 1-2, consists of a main beam, a central support and collector, a drive device, a scraper plate, a skimming device, a guide tube, a slag hopper, and a control cabinet.
Driven by the driving device, the main beam rotates around the central axis of the pool, and the scraper fixed on the scraper arm scrapes the sludge deposited at the bottom of the pool to the central mud collection pit. The scraper curve adopts a logarithmic spiral type, with uniform force and thorough scraping of mud. When there is an obstacle at the bottom of the pool, it can automatically release the scraper to protect the machine from damage. The driving device can be equipped with a torque protection device for safer operation.
1.Please specify when a skimming device, effluent weir plate, scum baffle, and effluent tank are required;
2.Specify equipment material, anti-corrosion, motor and reducer requirements;
3.When placing an order, please provide the civil engineering process diagram of the pool and indicate the detailed dimensions.
