LWZ Series Decanter Filtering Centrifuge

LWZ Series Decanter Filtering Centrifuge is a device integrating concentration, sediment and dewatering, designed on the basis of horizontal scroll discharge centrifuge structure, and added with filter-section basket. It is mainly composed of rotating body (basket combination, screw, big end shaft journal combination and small end shaft journal combination), differential gear, feeding pipe, machine base, housing, backflush device, power system, lubrication system and other components.

Detail

LWZ Series Decanter Filtering 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 two 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 heavier solid phase settles on inner wall of basket and is screw pushed to pre-concentration area at small end of basket for further concentrating, and pushed to filter section of basket under the action of screw. The sediments are further dewatered through centrifuging and filtering, and discharged from drainage port at small end of basket; during the dewatering process, the feeding pipe with jacket and washing agent can be used to clean sediment. The separation process is continuously operating. The clarified liquid, filter cake and filtrate is collected into collection bin in housing respectively, and discharged out of machine under the action of gravity. 

Product Structure 

LWZ Series Decanter Filtering Centrifuge is a device integrating concentration, sediment and dewatering, designed on the basis of horizontal scroll discharge centrifuge structure, and added with filter-section basket. It is mainly composed of rotating body (basket combination, screw, big end shaft journal combination and small end shaft journal combination), differential gear, feeding pipe, machine base, housing, backflush device, power system, lubrication system and other components. 

Product Features 

It is featured by higher speed, strong clarification capacity, small filter liquid leakage and low moisture content of filter cake. Compared with common decanter Centrifuge, it is designed with special filter section and low moisture content of filter cake; it can wash the filter cake inside machine; compared with pusher centrifuge, it is armed with special concentration section and better adapt to lower feeding concentration, so clarified liquid and filtrate can be discharged respectively; it is suitable to the concentrating and dewatering integrated operation for slurry with the concentration range of 2-50% and grain size of 0.05-5mm. The welded strip screen mesh is adopted and service life is prolonged; it applies the special dismantling tools, which are convenient for dismantling.
