Technical Field

[0001] The utility model relates to the technical field of calcination equipment, and particularly relates to a calcination device for gypsum whiskers. Background Art

[0002] Gypsum whiskers refer to fibrous single crystals of hemihydrate or anhydrous calcium sulfate, which are high-value industrial materials and are used as reinforcing agents or functional fillers in resins, rubbers, coatings, and papermaking. They can be used in friction materials, building materials, sealing materials, heat insulation and flame retardant materials, etc. In the production process of gypsum whiskers, a calcination furnace equipment is required for calcination. For example, the patent with the application number 201921165798.X discloses a gypsum whisker calcination device, which is provided with a corresponding cleaning mechanism to facilitate the discharge of materials after calcination, and has good practicability.

[0003] In the above design, after the cleaning mechanism is opened, the raw materials are discharged out of the equipment by relying on their own gravity. This method is prone to incomplete discharge, resulting in material waste. At the same time, the discharge is relatively slow and time-consuming.

[0004] Therefore, we propose a gypsum whisker calcination device. Content of the Utility Model
