Description

Technical Field

[0001] This utility model relates to the field of nonwoven fabric production technology, and in particular to a drying and leveling equipment for nonwoven fabric processing. Background Technology

[0002] Nonwoven fabrics release VOCs (volatile organic compounds) due to the slow release of these gases from their base material, auxiliaries, fillers, composite adhesives, and coatings. Therefore, a large amount of VOC waste gas is generated during the drying and leveling process. Direct emission of this waste gas would pollute the working environment and cause air pollution. Current technologies are not suitable for treating the waste gas generated during the drying and leveling process, resulting in limited functionality and failing to meet user needs.

[0003] Therefore, we propose a drying and leveling equipment for nonwoven fabric processing. Utility Model Content

Figures 1-4 As shown, the filter includes a processing box 1, a filter cylinder 2 fixedly installed at the top of the processing box 1, a metal condenser plate 3 fixedly installed on one side of the inner end of the filter cylinder 2, a refrigeration unit 4 fixedly installed on one side of the filter cylinder 2, the refrigeration unit 4 extending to the inner end of the filter cylinder 2, the refrigeration unit 4 being fixedly connected to the metal condenser plate 3, a metal support mesh plate 5 fixedly installed at the top of the inner end of the filter cylinder 2, activated carbon packing 6 being provided at the top of the metal support mesh plate 5, a water collection box 7 movably installed at the bottom of the inner end of the filter cylinder 2, a pull ring 8 fixedly installed on one side of the water collection box 7, and a door panel 9 movably installed on one side of the filter cylinder 2 near the activated carbon packing 6.

[0024] like Figures 1-4As shown, a protective top plate 10 is movably installed at the top of the filter cylinder 2. A through hole 11 is opened at the inner end of the protective top plate 10. A feed inlet 12 is opened on one side of the processing box 1, and a discharge outlet 13 is opened on the side of the processing box 1 away from the feed inlet 12. Guide rollers 14 are installed on both sides of the inner end of the processing box 1, located on the sides of the feed inlet 12 and the discharge outlet 13, respectively. A tension roller 15 is installed at the inner end of the processing box 1. A pressing table 16 is fixedly installed at the bottom inside the processing box 1. A fixing plate 17 is fixedly installed at the inner end of the pressing table 16. A motor 18 is fixedly installed at the bottom inside the pressing table 16. A fan 19 is fixedly installed on the output shaft end of 18. An electric heating mesh 20 is fixedly installed between the fixed plates 17. The electric heating mesh 20 is located on top of the fan 19. Air inlets 21 are opened on both sides of the pressing table 16. The air inlets 21 extend to the outside of the processing box 1. Air outlets 22 are opened on both sides of the top of the pressing table 16. A ventilation opening 23 is opened on the top of the processing box 1 on the side near the filter cylinder 2. The ventilation opening 23 is located at the inner end of the filter cylinder 2. An electric push rod 24 is fixedly installed on the top inside the processing box 1. An installation box 25 is fixedly installed on the transmission end of the electric push rod 24. A pressing roller 26 is installed on the inner end of the installation box 25.

[0025] Working principle: First, during the drying and leveling of the nonwoven fabric, the nonwoven fabric enters the processing box 1 through the feed inlet 12, passes through the guide roller 14 and tension roller 15 in sequence, and finally exits from the discharge outlet 13. During the conveying process, it passes through the pressing table 16. The electric push rod 24 pushes the mounting box 25 and the pressing roller 26 downward, interacting with the pressing table 16 to level the nonwoven fabric. The electric heating grid 20 is energized to generate heat, and the motor 18 drives the fan 19 to rotate, accelerating the airflow. The interaction with the electric heating grid 20 generates hot air to dry the nonwoven fabric. A large amount of waste gas is generated during the drying process, the main components of which include volatile organic compounds, dye particles, and humid hot water vapor. If directly... Emissions will pollute the working environment and cause air pollution. The exhaust gas enters the filter cartridge 2 through the vent 23. The water vapor in the exhaust gas liquefies after contacting the metal condenser plate 3, which can separate the water vapor from the volatile organic compounds, reduce the adsorption load of the activated carbon packing 6, and extend its service life. Then it drips into the water collection box 7. The refrigeration unit 4 continuously cools the metal condenser plate 3 to improve the liquefaction effect. Then the activated carbon packing 6 adsorbs and filters the organic compounds in the exhaust gas. The activated carbon packing 6 can be replaced periodically by opening the door plate 9. The metal support mesh plate 5 supports the activated carbon packing 6. The protective top plate 10 can prevent large foreign objects from falling into the filter cartridge 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
