Description

Technical Field

[0001] This utility model relates to the technical field of high specific surface area calcium hydroxide production, specifically to an auxiliary agent mixing device for producing high specific surface area calcium hydroxide. Background Technology

[0002] Calcium hydroxide is an inorganic powder material, typically produced by slaking quicklime and water. Due to its unique structure and properties, it has been widely used in wastewater treatment, sugar refining, coatings, and the metallurgical industry. In its production process, quicklime is calcined into lime, then crushed and slaked with water in a specific ratio to produce a calcium hydroxide slurry. This slurry is then purified, the residue is separated, centrifuged to remove water, and dried before being crushed into the final calcium hydroxide product. After slaking, the remaining calcium hydroxide slurry generally requires the addition of additives and thorough mixing to improve the quality and specific surface area of ​​subsequent products.

[0003] Existing additive mixing equipment suffers from several drawbacks. During the mixing process, the slurry tends to stick to the walls, causing calcium hydroxide slurry and additives to adhere to the inner wall of the container, affecting the mixing quality and resulting in material waste. Furthermore, the tank is difficult to clean after each production run, requiring a significant amount of time and manpower for equipment cleaning. Therefore, there is a need to propose an additive mixing equipment for the production of high specific surface area calcium hydroxide. Utility Model Content
