Description

Technical Field

[0001] The utility model relates to the technical field of chlorinated paraffin production and processing, in particular to a degassing kettle for chlorinated paraffin production. Background Art

[0002] During the production process of paraffin wax, chlorine gas needs to be introduced into the paraffin wax for a reaction to occur. As a result, the chlorinated paraffin wax will contain some hydrogen chloride vapor and unreacted chlorine gas. These gases can cause harm to the human body. After the relative density and chlorine content of the chlorinated paraffin wax reach the standards, the impurities contained in the chlorinated paraffin wax need to be removed.

[0003] According to a publicly disclosed degassing kettle for chlorinated paraffin production (publication number: CN220714897U), in the above application, a scraping device is used to assist the discharging process, shortening the discharging time, reducing material waste, and improving the economy and practicality of the equipment. A cleaning device is used to clean the inner wall of the equipment after the degassing work is completed, thereby improving the practicality of the equipment.

[0004] However, in actual use of the above-mentioned equipment, the inner wall of the tank is scraped off by a scraper plate to scrape off the chlorinated paraffin attached to the inner wall of the tank after degassing. However, the scraping is achieved by the vertical movement of the scraper plate, which makes the scraper plate have certain limitations during cleaning, especially when encountering harder solid impurities, one scraping may not be able to effectively remove them, thereby reducing the overall cleaning effect of the tank. In view of this, we propose a degassing kettle for the production of chlorinated paraffin. Summary of the invention
