Detail

LWL Series Horizontal Scroll Discharge Screen Centrifuge 

Product Principle

LWL Series Horizontal Scroll Discharge Screen Centrifuge is a machine that can continuously perform feeding, dewatering, washing, unloading and other process operations for suspension under a full speed. When the machine is running, firstly power it on and the host is turned on and automatically accelerates. When it reaches the preset value, feeding valve will be opened and materials to be separated enter into feeding pipe continuously, and are distributed to basket wall through feeding holes on wall at small end of screw. The liquid phase in suspension is discharged through filter screen and holes on basket wall under the action of centrifugal force, and discharged out of machine through filtrate outlet on housing while solid phase is retained on filter screen and forms a thin filter cake layer. In centrifugal force field, filter cake has a centrifugal force pointing at big end alongside the basket bus and a pushing force pointing at big end is generated when screw blade is rotating. Both forces will push filter cake to big end from small end of basket constantly, and filter cake is flipped by screw blade continuously in moving process, which greatly improve the separation process. The filter cake pushed out of big end of basket is discharged from drainage port of housing, and realizes the solid-liquid separation. 

Product Structure

LWL Series Horizontal Scroll Discharge Screen Centrifuge is mainly composed of rotating body combination (screw and basket etc.), differential gear, double motors (main motor and auxiliary motor), double frequency converters, integrated base, fully-closed housing, feeding pipe and automatic control system, and can perform solid-liquid separation, solid-phase dewatering and other processes multiple suspensions with large differences in material grain sizes.

Product Features 

It is featured by continuous operation, screw discharge and high production capacity, high dewatering rate of solid phase, good washing effect, high separation efficiency, compact structure and convenient for operation and repairing. LWL Series Horizontal Scroll Discharge Screen Centrifuge can be cylindrical or conical, and screw with different angles can determine the discharge speed and the time of filter cake retaining on filter screen. Such angle is determined by manufacturer according to process requirements. The material of centrifuge part contacting liquid can be made of austenitic stainless steel (321, 316…), hastelloy, titanium alloy or other anti-corrosion materials according to requirement of customers' materials. The following configuration can be provided according to customer's requirements: variable-frequency + PLC control, vibration, heating monitoring protection system of main bearing, feeding speed control, and gas-liquid separation device at discharge port.
