Description

Technical Field

[0001] The utility model relates to the technical field of wardrobe production and processing, in particular to an exhaust gas treatment device for a wardrobe production workshop. Background Art

[0002] Wardrobe production workshops often use a large number of chemical raw materials during the production process, such as various coatings, glues, varnishes, paints, and other surface treatment agents. These chemicals emit a large number of harmful gases during processing, including volatile organic compounds (VOCs), benzene, aldehydes, and organic solvents. These exhaust gases not only pollute the environment but also pose a health risk to workshop workers. Therefore, exhaust gas treatment has become a key issue that wardrobe production workshops must address.

[0003] For example, the Chinese patent with authorization announcement number: CN215388689U discloses an exhaust gas treatment device for a wardrobe production workshop, which relates to the field of wardrobe production and processing technology, including a main box, a purification mechanism and a disinfection mechanism. The movable tube is L-shaped, and one end of which is slidably connected to the inner cavity of the air inlet pipe, and the rotary joint is installed at the other end of the movable tube, the telescopic rod is fixedly connected to the bottom of the air inlet pipe, and the output end of the telescopic rod is fixedly connected to the movable tube, the dispersion disk is connected to the end of the movable box, the purification box is arranged at the bottom of the inner cavity of the main box, and the purification liquid is arranged in the inner cavity of the purification box. The utility model pushes the movable tube to move by the telescopic rod, so that the exhaust gas is evenly dispersed and discharged into the purification box, fully contacting with the purification liquid, thereby improving the purification effect, and when the movable tube moves, it will drive the filter to move, and by colliding with the iron ball, dust is not easy to clog the filter, effectively preventing dust from entering the purification mechanism, and further improving the use effect of the device.

[0004] Traditional wardrobe exhaust gas treatment devices usually use filters. Generally, after a period of use, the filters will be blocked and need to be replaced or cleaned by staff.

In addition, most traditional exhaust gas purification methods often use photocatalysis. The ultraviolet light source is prone to malfunctions when running for a long time. At the same time, long-term operation can easily lead to excessive temperatures, and the stability of the light source is easily affected. In order to protect the light source, the device has to be shut down for a rest, resulting in the equipment being unable to work for a long time and affecting its efficiency. Utility Model Content

[0032] The catalytic component includes a low-speed motor fixedly installed inside the light source box, the output end of the low-speed motor is fixedly connected to a fixed plate, and one side of the fixed plate is fixedly connected to several ultraviolet disinfection lamps.

[0034] Working principle: First, the exhaust pipe is connected to the air inlet 27, and the exhaust gas enters the filter 10. After being filtered by the filter 10, the dust and other impurities are blocked and fall into the receiving tray 5 at the bottom. Then the exhaust gas enters between the filter 10 and the outer shell 1, and then the top drive motor 32 drives the fan 33 to rotate, so that the exhaust gas enters the activated carbon adsorption plate 28 under the action of suction. The exhaust gas after adsorption treatment enters the purification box 2 along the aperture in the activated carbon adsorption plate 28. At this time, the ultraviolet disinfection lamp 17 can be started to further purify the exhaust gas. When the device is running for a long time, the low-speed motor 15 can be started, and the output end drives the fixed plate 16 to rotate, so that another group of ultraviolet disinfection lamps 17 on the plate are aligned with the irradiation hole 3, thereby starting another group of ultraviolet disinfection lamps 17 to disinfect the exhaust gas in the purification box 2, and then the other group is turned off to rest.

[0035] After a period of operation, a lot of dust and other impurities are blocked on the filter 10. This time, the dual-axis motor 20 can be started. The two output ends drive the inner bevel gear 21 and the outer bevel gear 22 to rotate. Then the inner bevel gear 21 is engaged with the inner auxiliary gear 23, driving the rotating frame 13 to rotate, so that the two inner gears 18 on the rotating frame 13 are engaged with the outer wall of the inner gear ring 11, and then rotate, so that the inner brush rod 19 rotates and revolves under the action of the rotating frame 13 and the inner gear 18, thereby achieving the cleaning of the inner wall of the filter 10. At the same time, the outer bevel gear 22 and the outer The auxiliary gear 24 engages, driving the driven gear 25 to rotate, thereby causing the outer gear ring 8 to rotate, driving the scraper 7 to clean the outer wall of the filter screen 10, and under the action of the rotation of the outer gear ring 8, the outer brush rod 9 will also rotate while sticking to the filter screen 10, and also assist in cleaning the outer wall of the filter screen 10. The impurities after the filter screen 10 is cleaned will automatically fall into the receiving tray 5 under the action of centrifugal force, preventing the filter screen 10 from being blocked, which can save the staff from replacing or cleaning the filter screen 10, and can also prevent dust and other impurities from blocking the filter screen 10 during the operation of the device.
