Full-bridge peripheral drive sludge scraper, sludge thickener, sludge suction machine for advection sedimentation tank

Structure and working principle
The central drive single-tube mud suction machine consists of a working bridge, a slag moving plate, a scraper arm, a central mud tank, a driving device, a central column, a central rotating vertical frame, a mud suction pipe, a scum baffle, a water outlet weir plate, and a water retaining skirt. It consists of plates, counterweight blocks, etc. The equipment adopts a central transmission vertical frame. The sewage enters the peripheral water distribution tank and flows evenly into the tank through the water distribution holes at the bottom of the tank. Under the action of the peripheral water retaining skirt, the water flows from the bottom of the tank to the center, and the sludge is deposited in the tank by its own weight. At the bottom, mud and water are separated, and the driving device drives the center vertical frame to rotate, and drives the scraper arm and mud suction pipe to rotate. Under the action of hydrostatic pressure, the sludge evenly enters the suction port arranged on the suction pipe, and is then discharged out of the pool through the sleeve valve of the central mud discharge well. The amount of sludge discharged outside the pool can be controlled by the lift of the sleeve valve. The scum on the water surface is spread to the edge of the pool through the scum removal device. Then the scraper rake scrapes it into the slag discharge hopper and discharges it out of the pool.

main feature
1. Adopting cross-sectional design, the mud suction port on the tapered mud suction arm is uniquely designed and adopts variable hole spacing, from the inside to the outside, from small to large, thus ensuring the mud discharge capacity of each mud suction hole and its other characteristics. The amount of settled sludge at the bottom of the loaded belt-shaped tank is matched, ultimately ensuring rapid sludge suction and high sludge discharge concentration;
2. Minimal sludge agitation, the return sludge is fresh and corrosion-free, and the effluent water quality is good; the underwater part adopts stainless steel structure to resist corrosion and have a long service life.
3. The driving device adopts a combination of helical gear reducer and turbine reducer to ensure the output torque and speed, and the transmission effect is high. The reducer is equipped with an over-torque protection device, making the operation safe and reliable;
The equipment is easy to operate, and the operation of the equipment can be controlled manually/remotely to achieve fully automated operation.
Application Scenarios
The sludge scraper and suction machine is suitable for scraping and removing sludge from radial flow (circular) sedimentation tanks with a diameter generally not larger than 20m in water supply and drainage projects or sewage treatment plants. The scraper and suction machine can be used in sewage treatment projects in urban, chemical, textile, metallurgical and other industries. Its structure is reasonable and easy to operate and maintain. It is an ideal supporting equipment for sewage treatment projects.:
