1, Purpose:
FLZG central drive mud scraper is suitable for radial flow sedimentation tanks with small and medium tank diameters of central water inlet, peripheral water outlet and central sludge discharge. It is mainly used for sludge discharge from sedimentation tanks of urban sewage treatment plants or industrial wastewater treatment projects.
2, Structure and working principle:
The equipment adopts central transmission, and the sewage flows into the water pipe from under the working bridge. After diffusion through the guide cylinder, it flows out evenly and radially to the periphery. The suspended sludge is deposited at the bottom of the tank after sedimentation. The driving device drives the central vertical shaft to rotate, and drives the scraper arm and scraper plate to rotate. After scraping and collecting the sludge, the scraper is pumped into the sludge collecting tank by the sludge suction pipe according to the static water pressure in the tank and discharged into the central sludge tank, and then discharged out of the tank through the central sludge discharge pipe. The scum on the water surface is introduced into the slag discharge bucket and discharged out of the tank through the rotary skimming device, The supernatant overflows into the outlet tank through the triangular outlet weir plate and is discharged.
3, Main features:
The working bridge adopts full bridge, which can be made of carbon steel, stainless steel or concrete structure; The driving device adopts vertical three-stage cycloidal pin gear reducer or the combination of helical gear reducer and turbine reducer to ensure the output torque and speed;
The scraper adopts linear scraper;
Underwater bearing and scraper are set at the lower end of the vertical shaft of the mud scraper to avoid deflection when the vertical shaft rotates and sludge accumulation in the sludge collecting tank; Set mechanical and electrical double overload protection to ensure safe and reliable operation; The equipment is easy to operate and can directly control the operation of the equipment locally and remotely. It can adapt to 20m diameter sedimentation tank Simple structure, high reliability and maintenance free It adopts high-performance driving device, with overload protection mechanism and torque display device Optional materials: carbon steel epoxy anticorrosion, carbon steel hot-dip galvanizing, stainless steel SS304 or SS316L Optional: rake lifting mechanism Optional: central guide cylinder, V-shaped outlet weir plate, slag skimming device (slag baffle and support, slag skimming plate, slag discharge cylinder, etc.)
