Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment technology in transfer membrane production, specifically a waste gas treatment device for transfer membrane production. Background Technology

[0002] During the production of transfer films, the drying process of inks or coatings generates waste gas containing pigments and fillers (such as calcium carbonate and silica). These incompletely dissolved solid particles form fine suspended matter after drying, which can pollute the environment if directly emitted and may also affect the normal operation of production equipment.

[0003] Currently, the common method for treating exhaust gas is to filter the exhaust gas using filter cartridges or filter elements to trap solid particles.

[0004] However, exhaust gas typically enters the filter element from a fixed direction, causing particulate matter to accumulate mainly on the side of the filter element closest to the air inlet, while the filter material in other areas is not fully utilized, reducing the overall lifespan of the filter element.

[0005] Therefore, we propose a waste gas treatment device for transfer membrane production. Utility Model Content

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] This embodiment is a waste gas treatment device for transfer membrane production.

[0026] like Figure 1-4 As shown, the device includes a processing tank 1. A support 2 is fixedly installed on the lower outer surface of the processing tank 1. An inspection cover 3 is installed on the upper part of the processing tank 1. An air inlet 4 is installed on the upper part of the inspection cover 3. An exhaust fan 5 is fixedly installed on the left outer surface of the processing tank 1. An exhaust port is provided at one end of the exhaust fan 5. An exhaust port 6 is provided on one side of the exhaust fan 5. A filter cartridge 9 is installed inside the processing tank 1. A sealing plate 10 is fixedly installed on the right outer surface of the filter cartridge 9. A connecting ring 11 is fixedly installed on the left outer surface of the filter cartridge 9. An annular protrusion 13 is fixedly installed on the left side of the connecting ring 11. A motor 7 is fixedly installed in the middle of the right outer surface of the processing tank 1. A rotating shaft 8 is connected to one end of the motor 7. A fixing ring 12 is fixedly installed on the left end of the inner cavity of the processing tank 1. An annular limiting groove 14 is opened on the right outer surface of the fixing ring 12. A rubber ring 15 is installed in the annular limiting groove 14.

[0027] One end of the exhaust port of the exhaust fan 5 passes through the fixing ring 12 and the connecting ring 11 and extends into the left end of the inner cavity of the filter cartridge 9; the outer surface of the end of the rotating shaft 8 away from the motor 7 is fixedly connected to the middle of the right outer surface of the sealing plate 10; a coupling is provided between the rotating shaft 8 and the motor 7, and the outer surface of the right end of the rotating shaft 8 is fixedly connected to the outer surface of one end of the output shaft of the motor 7 through the coupling; the connecting ring 11 is located to the right of the fixing ring 12, and the annular protrusion 13 is inserted into the annular limiting groove 14, and the annular protrusion 13 and the annular limiting groove 14 are rotatably connected; when the annular protrusion 13 is located in the annular limiting groove 14, the rubber ring 15 contacts and presses against the outer wall of the annular protrusion 13.

[0028] It should be noted that this utility model is a waste gas treatment device for transfer membrane production. The waste gas to be treated is sent into the treatment tank 1 through the air inlet 4. The operation of the exhaust fan 5 creates a negative pressure environment inside the filter cartridge 9, drawing out the gas and discharging it through the exhaust port 6. The waste gas is filtered by the filter cartridge 9, and impurities are retained on the outer wall of the filter cartridge 9. To prevent impurities from accumulating on one side of the filter cartridge 9, the operation of the motor 7 drives the rotating shaft 8 to rotate. The rotating shaft 8 drives the sealing plate 10 to rotate, and the sealing plate 10 drives the filter cartridge 9 and the connecting ring 11 to rotate. The connecting ring 11 drives the annular protrusion 13 to rotate in the annular limiting groove 14. The rubber ring 15 plays a sealing role between the annular protrusion 13 and the annular limiting groove 14, preventing unfiltered waste gas from entering the interior of the filter cartridge 9. The rotation of the filter cartridge 9 by the motor 7 prevents particulate impurities from accumulating only on one side of the filter cartridge 9, thus improving the service life of the filter cartridge 9.
