Description

Technical Field

[0001] The utility model relates to the technical field of gypsum board drying, and more specifically, to a super-thick paper-faced gypsum board drying device. Background Art

[0002] Extra-thick gypsum board refers to a building material that is thicker than traditional gypsum board. It is thicker than general gypsum board and is usually used in construction projects that require higher fire resistance or sound insulation performance. Extra-thick gypsum board needs to be dried during the production process to remove internal moisture.

[0003] After searching, the Chinese patent with publication number CN219474103U discloses a gypsum board drying device. The device cited in the device only cleans one side of the gypsum board when cleaning the surface of the gypsum board, and the other sides are not effectively cleaned; and the number of gypsum boards dried by the device each time is limited, so the drying of the gypsum board requires more time. Therefore, we propose a new gypsum board drying device, which moves the placed gypsum boards to the bottom of the cleaning component, at which time each gypsum board is located under each moving plate on the cleaning component, and then controls the second electric slider to move downward in the second slide slot, so that the moving block with a soft brush inside covers the gypsum board and the card strip below, and then brushes up and down, so that the dust and debris on the gypsum board can be effectively cleaned.

[0004] When the drying device is used to dry super-thick gypsum board, due to its thick thickness, there are problems of uneven drying and low drying efficiency. At the same time, during the hot air circulation process, a large amount of hot air is blown out once and then directly discharged, and a large amount of heat energy is still not utilized. In addition, since the gypsum board is super-thick, more heat energy is used, and its heat energy utilization rate is low. In addition, the humidity of the gypsum board evaporated into the air will affect the drying efficiency, which is likely to cause energy waste. Utility Model Content
