Background

The scraper of the chlor-alkali system caustic soda flake machine is used for scraping off molten alkali on a drum of the caustic soda flake machine to obtain a flaky caustic soda product with a specified thickness. In order to scrape the caustic soda flake cleanly without causing serious abrasion, the blade edge of the scraper is kept sharp firstly and kept at a proper distance from the surface of a rotary drum of the caustic soda flake machine secondly. After the scraper is used for a period of time, the scraper needs to be replaced because the edge of the scraper is passivated due to abrasion, so that part of molten alkali cannot be scraped off to influence the product quality. The service life of the scraper is directly related to the deformation degree of the caustic soda flake machine drum, and the scraper is replaced once in 1-2 months when the caustic soda flake machine drum is not deformed under normal conditions. With the increase of the service time of the rotary drum, the surface of the rotary drum can be locally deformed, the service life of the scraper can be shortened, the replacement frequency is increased, the service life is 15 days long, and the service life is 3-5 days short.
