Description

Technical Field

[0001] The utility model belongs to the technical field of gypsum calcining, and particularly relates to gypsum calcining equipment. Background Art

[0002] Calcination of gypsum particles is a key industrial process. Gypsum particles are placed in a specific high-temperature environment, and professional calcination equipment is usually used. Under the action of high temperature, the internal structure and composition of the gypsum particles change significantly, and the crystal water is removed. In modern industrial production, gypsum calcination equipment plays a vital role in the treatment of gypsum. However, as far as the common gypsum calcination equipment is concerned, after the calcination of the gypsum particles is completed, it is inconvenient to quickly discharge the finished product, which leads to many adverse effects on production. First of all, this inconvenience directly leads to a decrease in production efficiency. Since the gypsum cannot leave the equipment quickly, the calcination operation of the next batch cannot be carried out in time, and the operation cycle of the equipment is prolonged. This is undoubtedly a serious bottleneck for enterprises that pursue efficient production and meet market demand. In addition, the gypsum stays in the equipment for too long, and it is easy to be over-calcinated, which will affect the quality of the gypsum product, make its performance unstable, and reduce the qualified rate of the product. In order to solve these problems, it is urgent to develop a gypsum calcination equipment. Utility Model Content
