Product Description
XZXX Type Central Drive Single (Double) Pipe Sludge Suction Machine
XZXX type central drive single (double) pipe sludge suction machine is generally used for radial flow sedimentation tanks in large-scale wastewater treatment projects, especially suitable for scraping and discharging activated sludge at the bottom of secondary sedimentation tanks.
The process generally involves peripheral inflow, peripheral outflow, and central sludge discharge. The sludge is sucked to the center of the tank through the sludge suction pipe, and then the sludge discharge volume (recirculation ratio) is controlled by the sleeve discharge valve outside the tank body.
Its characteristics:
Peripheral water distribution is designed with uneven distribution according to hydraulic model test, ensuring uniform water distribution in the inlet tank and water distribution holes;
The central pier adopts steel structure design, reducing construction difficulty and ensuring transmission accuracy;
Vertical suction pipe, with reasonable counterweight, runs smoothly and reliably;
Water level and recirculation ratio can be adjusted and controlled;
Novel transmission device, large transmission torque and overload protection function;
The sludge suction port and scraper are specifically designed for thorough sludge discharge.
Working principle
Wastewater enters the unevenly distributed water distribution pipes through the peripheral variable-section water distribution tanks at a certain flow rate. Under the action of the baffle plates in the water distribution pipes, the flow rate is reduced, and under the action of the peripheral water distribution skirt plates, the inflow is evenly distributed from the bottom of the tank to the center. Inert and activated sludge in the water body settle to the bottom of the tank. The central drive single (double) pipe sludge suction machine installed in the tank body drives the scraping and suction sludge frame to rotate in the tank through the central rotating frame. The sludge suction pipe and scraper plate installed parallel to the bottom of the tank rotate accordingly. The inert sludge settled at the bottom of the tank is scraped into the central sludge collection pit and discharged outside the tank under the action of the scraper; the activated sludge settled at the bottom of the tank enters the sludge suction pipe under the action of the pressure difference between the water levels inside and outside the tank, and flows into the central sludge collection cylinder and is discharged outside the tank. The surface skimming device collects and scrapes the surface scum to the discharge hopper at the edge of the tank and discharges it outside the tank. The upper clear water bypasses the scum baffle and is evenly discharged into the outlet tank through the horizontally set outlet weir plate, entering the next process.
