THICKENER APPARATUS

Product Description

Specification:

THICKENER APPARATUS

Industrial sedimentation operationsmay be carried out batch wise and continuously in equipment called thickener.The equipment is a cylindrical tank with openings for a slurry feed and productdraw off.

The tank is filled with dilute slurryand slurry is permitted to settle. Continuous thickeners are large diameter,shallow depth tanks with slowly revolving rakes for removing the sludge. Theslurry is fed at the center of the tank. Around the top edge of the tank is aclear liquid overflow.

The rake serves to scrap the sludgetowards the center of the bottom for discharge. The motion of the rake alsostirs only the sludge layer. This gentle stirring aids in water removal fromthe sludge.

The set-up consists of several basiccomponents: a tank to contain the slurry, feed piping and a feed well to allowthe feed stream to enter the tank, a rotating rack mechanism to assist inmoving the concentrated solids to the withdrawal points, an underflowsolids-withdrawal system and an overflow launder.

A feed tank, feed pump, and feed tankagitator is provided. A bin for collecting concentrated material is alsoprovided.
