Drilling Solid Control Decanter Centrifuge

Working Principle

The separated liquid phase and sludge are discharged by gravity. The separated light phase will be discharged under pressure. The bowl is driven by an electric motor via drive belts. The bowl speed can be adjusted by a frequency inverter. The scroll is driven further by the secondary drive and the differential speed will be controlled via frequency inverter.

Introduction

Solids Control Decanting Centrifuge has advantages in wide adaptability great throughput,continuous and simple operation,easy installation, and small floor area, and is mainly used in petroleum,environmental protection industry,chemical, food, paper-making, brewing and amylum,industry etc.

The decanter separates suspension based on the pinciple of centrifugal settlement.A suspension is supplied to the rotating bowl through an  accelerator centrifugal force and transported towards the right shaft of the bowl by the conveyor and then discharged through solids discharge ports.While lighter liquid phase flows to liquid discharge ports at the left shaft of the bowl.

Structural features

The centrifug is used to separate solid and liquid in the rotary drum completely.It is mainly composed of rotary drum, screw conveyor, adifferential case and motors.

The rotary assembly is mounted on the two main bearing housings horizontally.The screw conveyor is installed in the rotary drum with deep groove ball bearing and tapered roller bearing. The main motor is connected with the fluid coupling by bell wheel. The differential casa is mounted on the left shaft of the bowl and is connected to the screw conveyor with mating splines. The main motor drives the fluid coupling and then drives the screw conveyor while the secondary motor drives the differential case.

TR Series Solid Control Decanter Centrifuge is typical drilling mud process equipment. It is 4th phase solids control equipment. Usually it's set behind mud cleaner or desilter. Mainly separate 2~7 microns particles. The complet conveyor and bowl will be made of S.S to provide high resistance for drilling mud. Furthermore, according to clients' requirement the drilling mud centrifuge can be designed as VFD type. Permits easy adjustment of bowl, conveyor, and feed pump speeds for varying process conditions and provides torque overload protection.
