Working principle

This machine is a flameproof horizontal spiral discharge settling centrifuge,It is a new type of product developed and designed by our companydecanter.The separation principle of the LWF series explosion-proof horizontal spiral discharge settling centrifuge is the same as that of the standard horizontal spiral discharge settling centrifuge. The main difference is that its structural design pays more attention to airtightness and safety. The centrifuge adopts a unique chamber sealing mechanism and is also equipped with nitrogen filling type sealing and nitrogen filling system, which eliminates the conditions for explosion formation through inert gas and special sealing structure to achieve explosion-proof effect. Dynamically detect and interlock the working status of centrifuges. Sealed centrifuges are mainly used in situations where the medium is volatile, difficult to ignite and explode. And the centrifugal pump pressure discharge is adopted to reduce the secondary gasification of the separation liquid, improve the sealing and safety of the centrifuge.

Separation technology

Feed → Inert gas protection→Gravity separation → liquid discharge → slag discharge.

Separation effect factors

Separation factor, effective cavity length to diameter ratio, and liquid pool depth.

field control

The rotational speed of the drum, the differential speed of the screw pusher, and the depth of the effective fluid separation pool are adjusted according to the liquid flow plate at the discharge port.

scope of application

Volatile, toxic, flammable and explosive materials.

Centrifuge parameter table

Processing capability description: The size of processing capability is related to the characteristics of the material

Centrifuge power description: The centrifuge power is determined based on the material characteristics and other factors

LW250, LW350, and LW450 are chamber sealed and explosion-proof according to the parameter table, while LW530 and LW650 are flip sealed structures
