Problems solved by technology
[0004] However, the disadvantage of the above-mentioned gypsum board drying equipment is that during the whole drying process, the inlet and outlet of the drying chamber are not closed, so that the hot air in the drying chamber is directly connected with the cold air outside. Contact, heat exchange, resulting in a large loss of heat

The invention belongs to the technical field of gypsum board processing equipment, and provides a gypsum board drying system, comprising a drying chamber, a plurality of layers of conveying rollers are arranged in the drying chamber, and a sealing device, the two sealing devices are respectively arranged in the drying chamber The feed port and the discharge port, the sealing device includes: an insulation board, and the insulation board has two working positions. When the insulation board is in the first working position, the insulation board will connect the feed end or outlet of the conveying roller of the corresponding layer. The material end is closed, and when the insulation board is in the second working position, the insulation board opens the feed end or the discharge end of the conveying roller table of the corresponding layer; the driving device, the two driving devices are respectively arranged on both sides of the installation bracket to drive The device is used for driving the thermal insulation board to reciprocate between the first working position and the second working position; and a locking device is used for locking the thermal insulation board in the first working position. The gypsum board drying system provided by the invention has lower heat loss.
Description
technical field [0001] The invention relates to the technical field of gypsum board processing equipment, in particular to a gypsum board drying system. Background technique [0002] The forming of gypsum board is to spread the slurry between the upper and lower protective paper, and form a fixed width and thickness through the molding device. The theoretical water consumption required for hydration of plaster of paris is 18.6% of its weight. In order to make the gypsum slurry have good fluidity, the ratio of water to paste often reaches more than 70%. This excess free moisture needs to be evaporated from the core during the drying process. In the process of water evaporation, the adhesive (modified starch) migrates to the interface between the cover paper and the surface layer of the gypsum core with the evaporation of water, and the cover paper and the gypsum core are firmly bonded together after gelatinization. Therefore, drying equipment is an important equipment for g...
