Description

Technical Field

[0001] This utility model relates to the field of waste gas treatment, and in particular to a detachable filter device for volatile organic waste gas treatment. Background Technology

[0002] Volatile organic compounds (VOCs) mainly originate from processes such as ink manufacturing, coal chemical industry, petrochemical industry, fuel coating manufacturing, and solvent manufacturing and use. They refer to organic compounds with a saturated vapor pressure greater than 70 Pa at room temperature and a boiling point below 260 °C at normal pressure, or all organic compounds with a vapor pressure greater than or equal to 10 Pa at 20 °C that are volatile.

[0003] Currently, most volatile organic compounds have an unpleasant odor and are toxic, irritating, teratogenic, and carcinogenic. In particular, benzene, toluene, and formaldehyde not only cause serious pollution to the atmospheric environment but also pose a great threat to human health.

[0004] However, in actual use, existing exhaust gas purifiers have particulate impurities in the exhaust gas. If these impurities are directly introduced into the activated carbon exhaust gas purifier, they will inevitably stick to the activated carbon filter screen. In severe cases, this can cause blockage of the activated carbon filter screen, resulting in reduced workload and efficiency. Furthermore, the filter mechanism of the exhaust gas purifier is mostly located inside the device, making it inconvenient to quickly disassemble and assemble the filter mechanism. Utility Model Content

[0005] In order to overcome the problems of existing exhaust gas purifiers, when the exhaust gas contains particulate impurities, if the particulate impurities are directly introduced into the activated carbon exhaust gas purifier, the particulate impurities will inevitably stick to the activated carbon filter screen, which will cause the activated carbon filter screen to become clogged in severe cases, resulting in reduced workload and efficiency. In addition, the filter mechanism of the exhaust gas purifier is mostly located inside the device, which is not convenient for quick disassembly and assembly.

[0006] The technical solution of this utility model is as follows: a detachable filter device for volatile organic waste gas processor, including a device shell, a pull-out seat movably connected to the rear end of the device shell, and limit blocks movably positioned on both sides of the rear end face of the pull-out seat.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5 This utility model provides an embodiment of a detachable filtration device for volatile organic waste gas processors, including a device housing 1. A pull-out seat 5 is movably connected to the rear end of the device housing 1. Limiting blocks 7 are movably positioned on both sides of the rear end face of the pull-out seat 5. One end of the limiting block 7 is located on the rear end face of the device housing 1 and is provided with a limiting seat 6. One end of the limiting block 7 is inserted into the inner side of the limiting seat 6. A servo motor 12 is fixedly connected to the bottom end of the pull-out seat 5. A filter cartridge 9 is fixedly connected to the top output end of the servo motor 12 on the inner wall of the pull-out seat 5. Filter plates 10 are fixedly connected to both sides of the filter cartridge 9 on the inner wall of the pull-out seat 5. A cleaning brush 11 is provided on the inner wall of the filter plate 10. One end of the cleaning brush 11 extends to the outer side of the filter cartridge 9. Thus, the filter plate 10 and the filter cartridge 9 on the inner side of the pull-out seat 5 cooperate with each other to improve the filtration effect of the device. During the rotation of the filter cartridge 9, the filter plate 10, in conjunction with the cleaning brush 11, cleans the surface of the filter cartridge 9.

[0024] Please see Figures 2-3 In this embodiment, an operation panel 4 is fixedly connected to the front end of the device housing 1. The operation panel 4 is electrically connected to the servo motor 12. An air outlet 2 and an air inlet 3 are respectively provided on the top and both sides of the device housing 1. The air outlet 2 and the air inlet 3 are connected to the device housing 1 through the air inlet 3, so that the waste gas is injected into the device through the air inlet 3, and then the filtered waste gas is discharged through the air outlet 2.

[0025] Please see Figures 4-5The bottom of the pull-out seat 5 has two sides with second movable grooves 13 on the inner wall of the device housing 1. The two sides of the pull-out seat 5 extend to the inner side of the second movable grooves 13. The pull-out seat 5 is movably connected to the device housing 1 through the second movable grooves 13. The inner wall of the pull-out seat 5 is provided with a sealing strip. The sealing strip is in contact with the device housing 1. The bottom of the limiting block 7 has a first movable groove 8 on the inner side of the pull-out seat 5. The bottom of the limiting block 7 extends to the inner side of the first movable groove 8. The inner wall of the first movable groove 8 is provided with a connecting spring 14. The limiting block 7 is movably connected to the pull-out seat 5 through the connecting spring 14. A coupling is provided at the intersection of the filter cartridge 9 and the servo motor 12. The filter cartridge 9 and the servo motor 12 are connected through the coupling. By sliding the limiting blocks 7 on both sides of the pull-out seat 5, the connection between the pull-out seat 5 and the device can be released, which is convenient for the user to disassemble and assemble the filter mechanism inside the device.

[0026] During operation, exhaust gas is injected into the device through the air inlet 3, and then the filtered exhaust gas is discharged through the air outlet 2. After the power is turned on and the device is started, the servo motor 12 drives the filter cartridge 9 to rotate.

During the rotation of the filter cartridge 9, the filter plate 10, together with the cleaning brush 11, cleans the surface of the filter cartridge 9. When the device is not in use, the connection between the pull-out seat 5 and the device is released by sliding the limiting blocks 7 on both sides of the pull-out seat 5, which makes it convenient for the user to disassemble and assemble the internal filtration mechanism of the device.

[0027] Through the above steps, the connection between the sliding seat 5 and the device is released by sliding the limiting blocks 7 on both sides of the sliding seat 5, which facilitates the subsequent disassembly and assembly of the filter mechanism inside the device by the user. The filter plate 10 and filter cylinder 9 on the inner side of the sliding seat 5 cooperate with each other to improve the filtration effect of the device. During the rotation of the filter cylinder 9, the filter plate 10, together with the cleaning brush 11, cleans the surface of the filter cylinder 9. This solves the problem that in the actual use of existing exhaust gas purifiers, because the exhaust gas contains particulate impurities, if it is directly introduced into the activated carbon exhaust gas purifier, the particulate impurities will inevitably stick to the activated carbon filter screen, which will cause blockage of the activated carbon filter screen in severe cases, resulting in reduced workload and efficiency. Moreover, the filter mechanism of the exhaust gas purifier is mostly located inside the device, which is not convenient for quick disassembly and assembly.
