Vertical Cuttings Dryer

(Vertical Scroll Discharge Screen Centrifuge)

Process | Working principle| Design Features| Application |Technical Parameters

Recently, government agencies continue to increase pressure toward protecting the environmentby placing stringent effluent limitations on the discharge of contaminated drill cuttings to the environment. For industries faced with this problem, HUADA manufactured LLL series cuttings dryer, also named vertical scroll discharge screen centrifuge

Process

Oil-Base Drilling Mud Bio-safety Disposal Project

Oil-base drilling mud bio-safety disposal mainly for the oil-base drilling fluids cuttings and the drilling mud can be collected for repeated use. Oil-base drilling mud enters into the shale shaker form the well, and the mud liquid enters into the high speed centrifuge, while the solids is transported to the cuttings dryer for further dewatering, then solids after dewatering will be transported to cuttings tank by screw conveyor, liquid flows into the liquid storage tank and for second treatment by the high speed centrifuge. Oil based drilling cuttings after treatment comply with the International Oil-base Drilling Fluids Cuttings Discharge Standards. It realizes industrialization of oil-base drilling mud cuttings disposal.

Working Principles

The suspension is introduced to the centrifuge through a feed pipe and into the feed distribution chamber, and is jetted into the basket through the inlet on the top of the scroll. Under centrifugal force the solids filtrate from the liquid and settle against the basket wall, while the clarified liquid exits over the overflow screen. The solids in the basket are conveyed up from the smaller end to the bigger end while the conveyor turns at a slightly different speed. The bigger diameter is, the bigger centrifugal force produces to separate the liquid/solids. The solids are dried when they are drained out the basket.

Design Features

♦Basket and scroll assembly are vertical design, which ensures stable operation and less vibration.

♦Main parts such as the basket and scroll are made of corrosion-resistant stainless steel or manganese steel.

♦Basket cone angle is optional depends on the process conditions.

♦Special designed bar shape filter metal screen, with better abrasive resistance and longer service life

♦Continuous operation includes feeding, separation, dewatering, discharging, with large capacity.

♦Independent lubrication systems, operates simple and reliable.

♦3K type planetary gearbox, with impact structure and large torque.
