Description

Technical Field

[0001] The utility model specifically relates to the technical field of drying with waste gas recovery, in particular to a silk screen drying device with a waste gas recovery structure. Background Art

[0002] After screen printing is completed, the product needs to be quickly dried, which can effectively avoid deformation or color bleeding of the screen-printed pattern on the product, and effectively ensure the quality and work efficiency of the screen printing department.

[0003] However, the traditional silk screen drying equipment does not have effective collection and treatment equipment for the waste gas generated during drying. First, this increases the production cost. Second, the harmful gases generated during drying cannot be filtered, which will pollute the working environment.

[0004] After searching, Chinese patent publication number CN202020911206.0 discloses a decorative button silk screen drying mechanism; including a transmission belt, a silk screen printing mechanism and a drying chamber, the silk screen printing mechanism is provided on the upper side of the transmission belt, a plurality of workbenches are provided on the upper end of the transmission belt, a drying chamber is provided on the left side of the silk screen printing mechanism, a plurality of fans are provided on the upper end of the drying chamber, and an electric heating wire is provided on the lower side of the fan;

[0005] The structure in the above patent blows the heat generated by the electric heating wire downwards through a fan during drying. Since the distance between the electric heating wire and the conveyor belt is large, the hot air becomes cool when it is blown downwards, so that the silk-screen products cannot be effectively dried. In addition, the waste gas generated by the structure in the above patent during drying cannot be effectively collected, which will cause the waste gas to pollute the working environment, and may even cause poisoning to personnel in severe cases.

[0006] In view of the above situation, we provide a silk screen drying device with a waste gas recovery structure. In this device, the silk screen products are effectively transmitted through the first conveyor belt and the second conveyor belt. During the transmission process, the heat generated by the heating tube on the top of the shell is blown to the silk screen products through the fan, and the effective drying effect of the silk screen products is achieved through heat. During drying, the waste gas generated is effectively extracted through a negative pressure machine that can be installed on one side, so that the waste gas generated during drying can be effectively centralized. The collected waste gas is transmitted to the inside of the gas collection and treatment box through the negative pressure machine and the pipeline, and the harmful gas in the waste gas is effectively filtered and adsorbed through activated carbon. The filtered gas is transmitted to the exhaust box through the air pipe and effectively discharged through the exhaust hole opened on the exhaust box. Utility Model Content
