Description

Technical Field

[0001] The invention relates to the technical field of glass fiber cloth drying equipment, and in particular to glass fiber cloth drying equipment. Background Art

[0002] Glass fiber cloth is mostly used in hand lay-up process. Glass fiber reinforced material woven cloth is mainly used in hulls, storage tanks, cooling towers, ships, vehicles, tanks, and building structural materials. This material absorbs a lot of heat when burned by flames and can prevent flames from passing through and isolate the air. Glass fiber cloth is mainly used in industry in the fields of heat insulation, fire prevention, and flame retardancy, and has been widely used. When glass fiber cloth is produced as raw materials or semi-finished products, there are procedures such as gluing and pressing. This process or other raw material processing procedures require drying of the grey cloth or semi-finished products.

The glass fiber cloth is rotated and conveyed in an upright state in the upright rotating conveying assembly. During the conveying process, the coated drying assembly passes hot air to the outer side of the glass fiber cloth, and the hot air passes through the glass fiber cloth to dry the glass fiber cloth. At the same time, the inner side of the glass fiber cloth is heated by the rotating heating assembly, and the ambient temperature in the coated seat is kept at a high level to increase the drying speed. The condensation guide assembly is provided by providing a plurality of condensation seats with funnel-shaped structures spaced apart in the vertical direction, and a condensation assembly is provided in the condensation seat, and adjacent condensation seats are connected by a guide pipe.

Condensed water, due to the funnel structure of the condensation seat, the condensed water gathers to the middle guide pipe due to gravity and enters the guide pipe through the water hole and gathers downward and is finally discharged through the drain pipe. On the one hand, by transporting the glass fiber cloth in an upright state, it is avoided that the condensed water drips onto the surface of the glass fiber cloth and affects the drying effect of the glass fiber cloth; on the other hand, the hot air blown out by the coated drying component not only dries the glass fiber cloth, but also promotes the movement of water vapor toward the condensation seat. After contacting the surface of the condensation seat, the hot water vapor liquefies into condensed water and is finally discharged from the drain pipe, avoiding affecting the movement direction of the hot air generated by the coated drying component. At the same time, due to the unidirectional flow of hot air, water vapor is also avoided from returning to the glass fiber cloth, avoiding the traditional direct use of exhaust method to directly extract the water vapor in the coated seat, thereby affecting the movement direction of the hot air and causing uneven drying, thereby improving the drying effect.
