Description

Technical Field

[0001] The invention relates to the technical field of scraper devices, in particular to a crystal wall scraper device. Background Art

[0002] A lot of wastewater and waste liquid will be generated in the process of industrial production. The equipment for treating wastewater will produce a large amount of heavy metals and colloidal organic matter during the evaporation and crystallization of wastewater, which will then form a crystal wall on the inner wall of the treatment tank. If these crystal walls are not cleaned in time, the treatment efficiency will be reduced. At this time, a scraper device is needed to scrape off the crystal wall on the inner wall of the treatment tank.

[0003] Considering that the wastewater contains a large amount of other impurities during the scraping process, it will affect the scraping effect of the scraper and cause damage to the scraper. At this time, the traditional scraper cannot meet the special processing requirements. Therefore, some scraper devices with special functions and structures can be applied to solve the above-mentioned problems.

[0004] Generally, traditional scraper devices can scrape off organic crystals containing heavy metals and colloids. Since the wastewater contains a large amount of garbage or non-degradable garbage, the internal position of the crystals is complicated. Some strong garbage will cause damage to the scraper during the scraping process. At the same time, the crystal structure containing other substances may increase the strength of the crystal wall, thereby hindering the scraping of the scraper. In the process of scraping, the direct acting part of the scraper structure will adhere to the crystals. After a large amount of accumulation, it will affect the normal use of the scraper structure, and the crystals inside the treatment tank cannot be effectively cleaned, thereby reducing the cleaning efficiency.

[0005] In summary, it is necessary to propose a crystal wall scraper device to solve the above problems. Summary of the invention
