Description

Technical Field

[0001] This utility model belongs to the field of cleaning the mouth of alkali replenishing tanks, and specifically relates to a cleaning device for the mouth of alkali replenishing tanks. Background Technology

[0002] In industrial production, alkali replenishment tanks are essential equipment used to add alkaline solutions to reaction systems to adjust the pH value. During long-term use, alkaline solutions (such as calcium hydroxide) can easily remain at the tank opening and react with carbon dioxide in the air to form precipitates such as calcium carbonate. These precipitates gradually accumulate and adhere to the surface of the tank opening, forming stubborn scale.

[0003] Currently, the cleaning of scale buildup at the mouth of alkali replenishment tanks mainly relies on manual labor. Workers stand on the second floor, wearing protective gloves, and use scrapers to clean the scale. Manual cleaning is not only inefficient but also poses certain safety hazards during the process.

[0004] Therefore, we propose a cleaning device for the mouth of an alkali replenishment tank to solve the above problems. Utility Model Content
