Product Description
LWF Continuous Solid/Liquid Separation Explosion-Proof Solid Bowl Decanter Centrifuge
Structure and principle of airtight seal
The gas-tight seal is a special structure consisting of the mechanical seal and inert gas supply device. It effectively prevents the external air from penetrating into the inner chamber of the centrifuge, and prevents the gas inside the centrifuge from leaking into the external environment.
The seal device consists of several seal rings and glands, and separates the inner chamber of the centrifuge from the surrounding environment. The inert gas is injected into the space among the seal rings, and then penetrates into the inner chamber of the centrifuge and the external environment through the narrow sealing clearance.
The pressure of inert gas is higher than those of the inner chamber of the centrifuge and the external atmosphere, therefore, entrance of air into the inner chamber of the centrifuge or escape of the gas out of the inner chamber of the centrifuge can be avoided.

Anti-corrosion
The materials to be separated are normally corrosive. So for safety, the parts in contact with these corrosive materials must be anti-corrosive.
Material of constructions: 304, 321, 316L, 904L, TA, 2205, 2507etc.
When there is determined application experience or corrosion data, carry out coupon test and laboratory verification to ensure selected material meet anti-corrosion requirements.
Surface anti-corrosion treatment: PE lined, rubber lined and halar lined and F40, F46, PFA etc.
Anti-corrosion requirements of sealing elements can not be neglected; material of sealing elements shall ensure prevention against corrosion from acids, alkali and solvents.
The customer shall forward the physical and chemical properties of the material and washing liquid (chemical properties and separation temperature etc.) to the manufacturer so that it can make recommendations for centrifuge materials based on characteristics of the separation medium, and that the suitable seal ring, seal washer and filter cloth can be provided, thus ensuring anti-corrosion requirements on the centrifuge.
Explosion-proof
If the centrifuge works in the environment, where there are some explosive substances, the centrifuge should be explosion-proof. If the centrifuge becomes really explosion-proof, it should take a variety of measures in mechanical, electrical control and the accessories selection.
Electric control: explosion-proof isolator, non-touch dynamic braking system, static grounding and explosion-proof automatic control.
Mechanical system: explosion-proof motor, explosion-proof light, anti-collision and anti-static driving belt.
Explosion-proof accessories: nitrogen protection system, on-site explosion-proof control button.
Therefore, for those environments required explosion-proof, users can specify the filtration medium, requirement and degree of explosion-proof when they take orders, in order to buy the right equipment to meet the requirements of explosion-proof.
