Description

Technical Field

[0001] The utility model relates to the technical field of gypsum whisker preparation, in particular to a gypsum whisker preparation device. Background Art

[0002] Gypsum whiskers are calcium sulfate fibrous single crystals synthesized from raw gypsum through a specific process and formula. They have a uniform cross section, a complete appearance, and a highly perfect internal structure. They are a non-metallic material with many special properties. In the process of whisker preparation, it is necessary to control the mixing and precipitation of the gypsum solution.

[0003] At present, when preparing whiskers, it is necessary to pour the dissolved liquid mixed with gypsum into the reactor for stirring and precipitation. The structure of the reactor is relatively simple. After the precipitation is completed, the staff needs to use tools such as scoop nets to manually salvage. This method is prone to omissions, and the salvage process is time-consuming and labor-intensive. When the mixed liquid is discharged and the crystals in the mixed liquid are screened, the whiskers are prone to blockage at the outlet of the reactor. The subsequent dredging not only affects the work progress, but also increases the cost, and the practicality is poor. Utility Model Content
