Technical Field
[0001] The utility model belongs to the technical field of scraper fixing devices, and particularly relates to a scraper fixing device which is easy to assemble and disassemble. Background Art
[0002] A centrifuge is a mechanical device that uses centrifugal force to separate and concentrate a mixed liquid (or a suspension of solid particles). It is widely used in many fields such as biomedicine, chemistry, pharmaceuticals, food, environmental protection, and mineral processing. There are many types of centrifuges. After separating the raw materials, some centrifuges need to use a scraper to scrape the separated materials on the inner wall. As a consumable part, the scraper will gradually wear out until it cannot be used as the use time increases. The scraper fixing device of the common scraper centrifuge has certain inconveniences in the disassembly and assembly of the scraper. The scraper cannot be disassembled and replaced after it is worn to a certain extent. In addition, the scraper needs to be disassembled and maintained during daily periodic maintenance to extend the service life of the scraper.
[0003] Secondly, a scraper fixing device that cannot be conveniently disassembled and assembled on the scraper may extend the time of its daily periodic maintenance accordingly during production, and the service life of the scraper may not be optimal. In addition, the inconvenience in disassembly and assembly will lead to prolonged disassembly and assembly time of the scraper, delaying the completion of normal production tasks.
[0004] In summary, the scraper fixing device is inconvenient to disassemble and assemble the scraper and has some problems during use, so it is hoped to propose a new structure to solve the above technical problems. Utility Model Content
