Installation dimensions of overhead rake scraperIt is located in the secondary sedimentation tank and includes a driving mechanism, a scraping mechanism, a suction mechanism, a mud collection mechanism, a mud discharge mechanism, and a support mechanism. The driving mechanism is located on the support mechanism, and the scraping mechanism and suction mechanism are connected to the driving mechanism. The suction mechanism is connected to the mud collection mechanism, and the mud discharge mechanism is located on the support mechanism, with one end connected to the mud collection mechanism and the other end connected to the outside of the sedimentation tank. The mud discharge mechanism includes a vacuum pump, a bend pipe, and a mud discharge pipe. The vacuum pump is located on the support mechanism, and the bend pipe is connected to the vacuum pump. The bend pipe is a double bend pipe formed in an inverted U-shape, with the bottom of the double bend pipe. Insert into the mud collection mechanism, with one end of the mud discharge pipe connected to the double bend pipe and the other end connected to the outside of the sedimentation tank.

1. The inlet groove adopts a design of variable cross-section, variable flow rate, and variable head, ensuring the uniformity of the inlet water;

2. Cone shaped suction pipe with variable aperture and spacing suction holes, allowing for uniform and proportional collection of sludge at the bottom of the entire pool, achieving a one-time suction of sludge;

3. Novel structure, lightweight, uniform sludge discharge, stable operation, overload alarm, operation;

4. High surface load, low power consumption, easy maintenance, and low operating costs;

5. Electrical control can be customized according to customer requirements, and customers can choose control features such as manual, semi-automatic, PLC control, and remote communication.

Operating principle: By driving the mechanism, the rotating frame is driven to rotate, thereby driving the scraper mechanism to rotate, to scrape the sludge at the bottom of the sedimentation tank. Then, through the suction mechanism, the sludge is sucked into the collection tank of the sludge collection mechanism, and then through the discharge mechanism, using the siphon principle, the sludge is discharged into the sedimentation tank through the discharge pipe. The floating slag on the upper part of the sedimentation tank is scraped into the sludge hopper by the scraper plate of the slag automatic flushing mechanism, which follows the rotation of the scraper mechanism. The floating slag is then washed into the discharge pipe and flushed out of the sedimentation tank through the cleaning device installed on the inner wall of the sludge hopper.

Due to its segmented manufacturing, compact connection, on-site assembly, and good interchangeability, it ensures overall strength and stiffness. In addition, the drive mechanism has a simple structure, using only the small gear of the SEW reducer to drive the large internal gear at the upper end of the mud collection tank. The main transmission parts are all universal connections, reducing motion resistance by 60% -70% compared to general mud scrapers, reducing electricity consumption by 40% compared to general mud scrapers, saving 30% of raw materials and saving 0.4t of flushing water per day compared to mud scrapers with the same processing capacity.
