Description

Technical Field

[0001] This utility model belongs to the field of gypsum board production technology, specifically relating to a paperless gypsum board production equipment. Background Technology

[0002] The production of paperless gypsum board involves mixing gypsum slurry and pouring it into molds for shaping. The gypsum board production process is relatively simple. The main raw materials include gypsum, cellulose, and additives. These raw materials need to be prepared and stored according to a specific ratio. Gypsum powder, cellulose, and other additives are mixed using stirring equipment to ensure thorough and uniform mixing. After molding, the boards undergo impregnation and curing processes to ensure their strength and stability, resulting in paperless gypsum board that meets specifications. Finally, the molded gypsum board undergoes drying to remove moisture and improve its stability and quality.

[0003] Some gypsum board drying is carried out through hot air circulation furnaces. Hot air acts on the boards. Since there is a certain space inside the furnace, dust or foreign objects carried in the hot air can easily affect the surface of the gypsum board, thereby reducing the quality of production.
