Raking arms attached to the centre shaft and drive rotate to direct the settled solids to the discharge cone from which thickened slurry is pumped out of the unit. The following paragraphs will explain the main thickener parts in more detail. Tank. The tank is constructed from a variety of materials, the most common being mild steel and concrete.
1. The influent pipe must be buried beneath the thickener basin. 2. Tanks are generally concrete to adequately support the center column. 3. Center column and cage are more expensive than shaft driven rakes in smaller diameter tanks.
Cage drive units are suitable for larger thickeners and can provide the torque needed in heavy duty thickening applications. The cage drive is supported by a steel center column. These units transmit torque from a fabricated steel drive unit with precision bearing and gear through a center cage of box truss construction.
Cage Driven. "PARAMOUNT" make picket fence type sludge thickener mechanism is suitable for installation either in RCC/MS basin. The recommended slope is 1:12 at the bottom of the tank for efficient removal of the sludge. The sludge is scrapped from the bottom of the tank by rotating scrapper arm. PARAMOUNT make cage driven sludge thickener ...
Suitable diameter of Influent well made out of MS or FRP bolted to the Center Scraper Cage Feed inlet to the Thickener is through the hollowed civil Centre pier bottom or pipe at the top Two Scraper arms, truss type fabricated fixed to Centre Scraper Cage suspended from the Centre mechanism to sweep the tank floor with Scraper blades, Neoprene Rubber squeezes
Centrally Driven With Center Cage Thickener. The mechanism would be of centrally driven type with fixed half bridge spanning the tank radius. One end over the tank wall and other over a Centre mechanism cum turn table in the Centre
The drive head, together with the raking arms, are the heart of the mechanism since the entire operation of the thickener depends on their ability to convey
Bridge and mechanism modernizations can replace all internal elements of your thickener, including bridge, gearboxes, power units, rakes, and torques shafts or cages. The latest equipment design takes into consideration improved safety features. Possibility of reusing existing tank and supports.
