Technical Field

The invention relates to the technical field of centrifuges, in particular to a clean type vertical scraper lower discharging centrifuge.

Background

Centrifuges are machines that utilize centrifugal force to separate components of a mixture of liquid and solid particles or liquid and liquid. The centrifuge is mainly used for separating solid particles from liquid in suspension, or separating two liquids which have different densities and are insoluble with each other in emulsion (for example, cream is separated from milk); it can also be used to remove liquids from wet solids, such as by spin drying clothes in a washing machine; the special overspeed tubular separator can also separate gas mixtures with different densities; some settling centrifuges can also grade solid particles according to density or granularity by utilizing the characteristic that solid particles with different densities or granularities have different settling speeds in liquid.

The centrifuge is widely applied to solid-liquid separation in chemical industry, pharmaceutical industry and other industries, and the existing centrifuge needs to integrally disassemble a rotary drum when being thoroughly cleaned due to the fact that a structural dead angle which cannot be cleaned by touch exists between the rotary drum bottom and a bearing seat in the using process, so that the centrifuge is inconvenient for users to use, and particularly the centrifuge is difficult to meet the requirements of the users when being used in the pharmaceutical industry, so that the centrifuge with the clean vertical scraper can be used for solving the problems.
