Description

Technical Field

[0001] The utility model belongs to the technical field of centrifuge scraping, and in particular relates to a centrifuge scraping component. 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 (e.g., separating cream from milk); they can also be used to remove liquids from wet solids, such as using a washing machine to spin dry wet clothes; special ultra-fast 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. When a centrifuge is in use, its inner wall is prone to adsorb impurities, so a scraper assembly is required to clean the impurities.

[0003] The patent with application number 202122696667.8 discloses a retractable centrifuge scraper mechanism, including a threaded rod, a movable component, a chassis, a scraper component and a fixed component. The movable component is arranged on the threaded rod, and the chassis is rotatably connected to the movable component. The scraper component is arranged on the movable component, and the fixed component is symmetrically arranged at both ends of the threaded rod. The scraper component is arranged to scrape the material on the inner wall of the centrifuge from the upper and lower and rotational directions, so that the material is scraped more cleanly, thereby improving the scraping efficiency and avoiding material waste.

[0004] The above technical solution uses a scraper assembly embedded in the centrifuge to clean impurities. However, since the scraper assembly is fixed in the centrifuge body, the scraper assembly will block the centrifugal product when the centrifuge is in use, affecting the normal use of the centrifuge.
