Description

Centrifugal Separator for Silicon Carbide Production

technical field

The utility model relates to solid-liquid separation equipment, in particular to a centrifuge for silicon carbide production.

Background technique

Centrifugation is to use the strong centrifugal force generated by the high-speed rotation of the centrifuge rotor to accelerate the sedimentation speed of the particles in the liquid, and separate the substances with different sedimentation coefficients and buoyant densities in the sample. Therefore, it is necessary to use a centrifuge to generate a strong centrifugal force to force these particles to overcome diffusion and produce sedimentation motion.

Centrifuges can also separate components in a mixture of liquids and solid particles or liquids and liquids. The centrifuge is mainly used to separate the solid particles in the suspension from the liquid, or to separate two different densities and immiscible liquids in the emulsion, such as separating cream from milk; it can also be used to remove moisture Liquid in solids, such as drying wet clothes with a washing machine; special ultra-speed tube separators can also separate gas mixtures of different densities; using the characteristics of different sedimentation velocities of solid particles of different densities or particle sizes in liquids, some sedimentation centrifuges The machine can also classify solid particles according to density or particle size.

Centrifuges are widely used in chemical, petroleum, food, pharmaceutical, mineral processing, coal, water treatment and other departments.

According to the structure and separation requirements, industrial centrifuges can be divided into three categories: filter centrifuges, sedimentation centrifuges and separators.

In the production of silicon carbide, solid-liquid separation is required, and a centrifugal separator is used. However, existing centrifuges have the disadvantages of complex structure and inconvenient maintenance.
