The gypsum board is a novel building material with light weight, excellent heat preservation and heat insulation effects, and is more and more widely applied. The production speed of the gypsum board is the key for restricting the production of the gypsum board, and the coagulation time of the gypsum can be greatly shortened by adding the coagulant, so that the production speed of the gypsum board is increased.
Potassium sulfate is a commonly used accelerator for gypsum board, but it adversely affects the quality of the gypsum board product. The product prepared by grinding waste gypsum board or saw-edge dust-collecting powder as raw material can also be used as gypsum board coagulant, but the coagulant has the problem that paper scraps are difficult to remove, and the waste board and dust-collecting powder contain various additives to influence the coagulation accelerating effect.
At present, the research on gypsum board setting accelerators at home and abroad focuses on preparing the setting accelerators by using gypsum as a raw material and changing the particle size distribution through ball milling. However, the coagulant is extremely easy to damp and agglomerate, and the coagulation accelerating effect is greatly reduced after the coagulant is placed in a high-temperature humid environment for 0.5-1 h. However, in the industrial production of gypsum boards, the amount of the setting accelerator is required to be combined with various factors such as gypsum raw materials, gypsum board production speed and environment, and in order to ensure continuous production, the gypsum setting accelerator is prepared in advance and stored for later use in industry, which greatly affects the setting accelerator effect of the gypsum setting accelerator.

The control device comprises a temperature control unit.
As shown in fig. 2, the conveying stirring device 2 may include a spiral piece 21, and the driving device is configured to drive the spiral piece 21 to rotate. When the spiral piece 21 rotates, the material inside the housing 1 is brought to rotate together and is conveyed forward along with the spiral channel of the spiral piece 21.

When the equipment of this application is used for producing gypsum, as shown in fig. 5, wet gypsum raw meal continuously enters the shell 1 from the feeding port and is stirred and conveyed forward under the rotation of the conveying and stirring device 2, the wet gypsum raw meal is dried by the electric heating device or hot fluid in the shell 1 during the conveying process, and materials at different positions of the shell 1 can be dried to different degrees due to different staying time inside the shell 1, and the drying is expressed as different water loss degrees. This application can realize the output of the gypsum of different dehydration degree through set up a plurality of discharge gates 3 on casing 1, for example, follow the output of gypsum discharge gate 31 and detach the dihydrate gypsum that attaches water just, export the calcined gypsum from the calcined gypsum discharge gate 32 that is located novel horizontal equipment afterbody. The dihydrate gypsum with the attached water removed right away can be immediately conveyed to a grinding device for producing the gypsum coagulant after being output, and the output dihydrate gypsum is in an amount which can ensure that the produced gypsum coagulant can meet the requirement of continuous production of gypsum boards. In this way, even if the gypsum board production line is adjusted, a proper amount of dihydrate gypsum can be output as required, and the remaining dihydrate gypsum is continuously dried in the casing 1 until the dihydrate gypsum is converted into gypsum clinker.
Generally speaking, the gypsum coagulant used for producing gypsum boards is small in amount, the mass of the gypsum coagulant accounts for 0.2-5% of the mass of the clinker, and the equipment can be used for preparing the dried gypsum on site without causing excessive storage of the dried gypsum, so that the coagulation accelerating effect of the gypsum coagulant prepared from the dried gypsum is improved.
