Product Description
PRODUCT DESCRIPTION
LW DECANTER CENTRIFUGES
LW series products are decanter centrifuges that can work continuously and are mainly used for solid-liquid separation, dehydration, fractionation, clarification, and concentration of materials. Based on different phase densities, it separates the solid phases and liquid phases under the action of the centrifugal force generated by the high-speed revolution of the Bowl. The solid phases are conveyed to the conical end of the Bowl through a spiral and then discharged, and the liquid phases are discharged out from the overflow port at the big end of the Bowl. Characterized by simple design, high efficiency and scientific configuration, this product has been widely applied to chemical, pharmaceutical, environmental protection, food, mining, energy and other industries.
LW Decanter Centrifuges (Standard Type)
Labyrinth seal is adopted for both ends of the Bowl of the standard type of the LW series, which is simple yet efficient. After separation, the solid phases are pushed to the solid discharge outlet through a spiral and then discharged out of the Bowl under the action of the centrifugal force generated from high-speed revolution, and the clarified liquid is discharged out of the overflow port at the big end of the Bowl. Featuring simple operation, stable operation, high efficiency and high automation, and continuous working of 24 hours, this type is widely applied.
MAIN TECHNICAL PARAMETERS
LWS Three-phase Decanter Centrifuges (Tricanter)
This type is mainly used for solid-liquid-liquid separation, which means to separate a solid phase (with its density being the maximum) with two liquid phases of different densities. Based on a certain differential, the Bowl and spiral revolve in the same direction at high speeds, and the materials enter the equipment through the feeding pipe. Under the action of centrifugal force, the solid matters will deposit to form a sediment layer on the Bowl wall, and the two liquid phases will form a light liquid ring and a heavy liquid ring respectively, successively forming a solid layer, light liquid layer and heavy liquid layer inward from the Bowl wall. The spiral works continuously to push the solid matters on the Bowl wall to the conical end of the Bowl and then discharge them out of the equipment through the slag discharging port. The light liquid phase continuously flows out of the overflow port at the big end of the Bowl, while the heavy liquid phase is discharged out through the centripetal pump also at the big end. Thus, continuous separation of three phases is realized.
MAIN TECHNICAL PARAMETERS
LWFX Gas-tight Decanter Centrifuges (Explosion-proof Type)
This type of centrifuge is mainly used in the chemical, petrochemical and pharmaceutical industries involving flammable and explosive occasions. In the process of solid-liquid separation, gases are not allowed to leak into the extraneous air, or extraneous air is not allowed to enter the equipment, or it may lead to explosion. The product is configured with an airtight seal with automatic compensation function, which allows a dynamic enclosed space with micro-positive pressure to be formed inside the centrifuge during the process of operation, so as to realize good sealing and explosion-proof effect.
STRUCTURE AND PRINCIPLE OF AIR-TIGHT 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.
