LWS Series Three-phase Decanter Centrifuge

LWS Series Three-phase Decanter Centrifuge is mainly composed of rotating body combination (screw and basket etc.), planetary gear differential, double motors (main motor and auxiliary motor), double frequency converters, integrated base, fully-closed housing, feeding pipe assembly, adjustable centripetal wheel, hood and automatic control system, and can perform liquid-liquid-solid or liquid-solid-liquid three-phase separation for multiple suspensions with large differences in materials.

Detail

LWS Series Three-phase Decanter Centrifuge

Product Principle

Host is turned on and automatically accelerates up to preset speed. Open the feeding valve and the suspension to be separated enters into stock bin of screw pusher through feeding pipe, and enters basket from bin outlet after preliminarily accelerating. The suspension in basket is divided into three phases quickly under the action of centrifugal force. The differential action of differential gear makes relative movement generated between screw pusher and basket, and the heaviest solid phase settles on inner wall of basket and is screw pushed to drying area at small end of basket for further dewatering, and discharged through drainage port. At the same time, the heavier liquid phase (such as water) is close to inner wall of basket while lighter liquid phase (such as oil) is distant from inner wall of basket. The overflow baffle plate at big end of basket can adjust and realize the separation effect of different sediments and liquid phases, and also can realize the different separation effects for two liquid phases through adjusting the interface between two liquid phases by using adjustable centripetal wheel without the need of shutting down. The separated light liquid (such as oil) is discharged through overflow port while the separated heavy liquid (such as water) is discharged by centripetal pump at big end of basket. 

Product Structure 

LWS Series Three-phase Decanter Centrifuge is mainly composed of rotating body combination (screw and basket etc.), planetary gear differential, double motors (main motor and auxiliary motor), double frequency converters, integrated base, fully-closed housing, feeding pipe assembly, adjustable centripetal wheel, hood and automatic control system, and can perform liquid-liquid-solid or liquid-solid-liquid three-phase separation for multiple suspensions with large differences in materials.

Product Features 

Except the features of common decanter centrifuge, it also covers the following features: it can adjust separation area of two liquid online relying on adjustable centripetal wheel; the heavy-phase liquid is discharged under pressure while light-phase liquid is discharged under the action of gravity; it can quickly and freely adjust the separation degree of heavy-phase and light-phase liquid to get liquid with higher purity; the adjustable centripetal wheel saves the traditional separation pump, saves cost and adjusts scale, which is convenient to read and easy to operate; it can directly enter discharge pipe from inner cavity of basket through the centripetal pump, and two liquid phases are discharged from individual channels, which effectively avoid cross contamination of heavy liquid and light liquid; it can adapt to the proportion changes of feeding volume and three-phase feeding concentration in real time.
