ZGA type scraper with central drive
Purpose:
ZGA vertical frame center drive mud scraper is suitable for radial flow sedimentation tanks with medium and large tank diameters with central water bursting, peripheral water outlet and central sludge discharge, and is mainly used for sludge discharge from secondary sedimentation tanks of urban sewage treatment plants
Structure and working principle:
The equipment adopts central transmission and vertical rack type. After the sewage flows into the diversion cylinder from the inlet pipe and diffuses, it flows out evenly in a radial shape to the periphery. The suspended sludge is deposited at the bottom of the tank after sedimentation. The driving device drives the central vertical frame to rotate, and drives the scraper arm and scraper plate to rotate. After scraping the sludge from the periphery of the tank to the central sludge collecting tank, it is discharged from the sludge discharge pipe outside the tank by the static water pressure in the tank, The scum on the water surface is skimmed to the side of the pool through the slag removal device, and then scraped into the slag bucket by the slag scraper and discharged out of the pool; The supernatant overflows into the outlet tank through the triangular outlet weir plate and is discharged.
Main features:
1. The working bridge adopts half bridge type, and its material can be carbon steel or stainless steel structure;
2. The driving device adopts the combination of helical gear reducer and worm gear reducer to ensure the output torque and speed and high transmission effect;
3. The reducer is equipped with over force torque protection device, which can operate safely and reliably;
4. The equipment is easy to operate and can directly control the operation of the equipment locally / remotely
1. It can adapt to the sedimentation tank with a diameter of 10 ~ 40m, with simple structure, high reliability and maintenance free
2. It adopts high-performance driving device, with overload protection mechanism and torque display device
3. Optional materials: carbon steel Epoxy Corrosion protection, carbon steel hot-dip galvanizing, stainless steel SS304 or SS316L
4. Optional: central column, central guide cylinder, V-shaped outlet weir plate, slag skimming device (slag baffle and support, slag skimming plate, slag discharge cylinder, etc.)
