Description

Technical Field

[0001] The utility model mainly relates to the technical field of centrifuges, and in particular to a centrifuge which is easy to clean. Background Art

[0002] A centrifuge is a machine that uses centrifugal force to separate liquids from solid particles or components in a mixture of liquids and liquids. Centrifuges are mainly used to separate solid particles from liquids in suspensions, or to separate two immiscible liquids of different densities in emulsions; they can also be used to remove liquids from wet solids; special ultra-speed tubular separators can also separate gas mixtures of different densities; some sedimentation centrifuges can also classify solid particles by density or size, taking advantage of the fact that solid particles of different densities or particle sizes have different sedimentation speeds in liquids.

[0003] After a centrifugal operation is completed, the inner wall of the current centrifuge will be stained with a lot of residual liquid and needs to be cleaned. For example, Chinese patent publication No. CN218690530U discloses a centrifuge that is easy to clean, including a centrifuge body, a sealing cover is provided on the centrifuge body, a drum is rotatably mounted on the sealing cover, a power assembly for driving the drum to rotate is provided on the drum, and a lifting component is installed inside the drum.

[0004] In the above application, when the centrifuge body needs to be cleaned, the lifting component drives the mounting cylinder to pass through the perforation into the centrifuge body, and then the water source passes through the water supply pipe and is sprayed out from the nozzle to wash the inner wall. At the same time, the driving component drives the rack to continuously reciprocate up and down, thereby driving the wheel to continuously reciprocate up and down, so that the nozzle continuously swings up and down, and the inner wall of the centrifuge body can be fully washed. However, the above application can only clean the inner wall of the centrifuge body, and cannot clean the filter drum. If the residue in the filter drum is not cleaned in time, it will lead to the accumulation of pollutants, which will reduce the filtration efficiency and affect the quality of the final product.
