The peripheral drive mud scraper and suction machine is mainly used for radial flow sedimentation tank with a diameter of about 20m in water supply or drainage engineering.
The peripheral driving mud scraper and suction machine mainly includes steel beam, overflow weir, driving device, steady flow cylinder, central mud tank, sludge discharge tank, scraper, mud suction device, Scum Collection and discharge facilities, and power transmission and gas transmission device.
The water to be treated enters from the inlet pipe of the central cylinder, enters the sedimentation tank through the steady flow cylinder, and then diffuses and settles around. The clean water flows out from the overflow weir at the side of the tank, in which the sediment is concentrated to the sludge suction port by the sludge scraper, mixed by the compressed air disturbance and increased oxygen to increase the sludge activity. According to the principle of connecting pipe, the sludge at the bottom of the tank is sucked into the sludge discharge tank by using the water level difference, and discharged through the siphon into the sludge discharge pipe of the central cylinder. At the same time, scum in the tank is collected by scraper and discharged out of the tank through slag discharge hopper.
