DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 6, the present utility model provides a technical solution: a quick-release exhaust gas filtering device, including a device body 1. A circulating spray assembly 2 is embedded in the back surface of the device body 1. A quick-connection assembly 3 is fixedly connected to the docking part on the front surface of the device body 1. A filtering assembly 4 is slidably connected to the inside of the device body 1.

[0027] The device body 1 includes a housing 101. A cover plate 107 is hingedly connected to the top of the housing 101. A water inlet pipe 102 is embedded in the center of the top of the cover plate 107. First blowers 103 are embedded on both sides of the top of the cover plate 107. A second blower 104 is embedded in the lower part of one side of the housing 101. An air inlet pipe 105 is installed at one end of the second blower 104. A support frame 106 is fixedly connected inside the housing 101.

[0028] The circulating spray assembly 2 includes a water outlet pipe 201 embedded in the back surface of the housing 101. A water pump 202 is installed at one end of the water outlet pipe 201. A first water inlet pipe 203 is installed at one end of the water pump 202. A U-shaped pipe 204 is installed at one end of the first water inlet pipe 203. Spray heads 205 are evenly installed at the bottom of the U-shaped pipe 204. A second water inlet pipe 206 is installed at the top of the U-shaped pipe 204. A socket joint 207 is installed at one end of the second water inlet pipe 206.

[0029] The quick-connection assembly 3 includes a fixed buckle 301 fixedly connected to the center of one end of the cover plate 107. A handle 302 is embedded at one end of the fixed buckle 301. A connecting rod 303 is fixedly connected to one end of the handle 302. The connecting rod 303 horizontally penetrates through the inside of a spring 304.

[0030] The filtering assembly 4 includes a filter tank 401 slidably connected to the top of the support frame 106. A handle 402 is fixedly connected to the center of one end of the filter tank 401. A fixing frame 403 is fixedly connected to the inner bottom of the filter tank 401. A filter screen 404 is movably connected to the top of the fixing frame 403. A pull ring 405 is fixedly connected to the center of the filter screen 404.

[0031] In this embodiment, as Figure 1 and Figure 3 shown, grooves are provided on both sides of the top of the support frame 106; through this design, the filtering assembly 4 can be extracted by sliding in the grooves, which facilitates the disassembly of the filtering assembly 4 for cleaning work, reduces the time and pulling force required for the staff to disassemble, and increases the efficiency and effect of subsequent exhaust gas filtering.

[0032] In this embodiment, as Figure 1 and Figure 3As shown, a fixing block is fixedly connected to the center of the top of the front surface of the outer shell 101, and a slot is provided at the center of the fixing block. An activated carbon filter layer is installed at the bottom of the first blower 103. Through this design, when the cover plate 107 is closed, it can be quickly fixed through the quick-connection assembly 3, making the device have a certain stability and preventing the cover plate 107 from slipping and causing waste gas leakage. When the cover plate 107 is opened, the activated carbon filter layer can also be cleaned, further filtering the discharged gas and increasing the waste gas filtering efficiency.

[0033] In this embodiment, as Figure 2 and Figure 4 shown, the aperture of the water outlet pipe 201 is larger than that of the first water inlet pipe 203. Through this design, the filtered water liquid can undergo a certain pressure change, resulting in a better spraying effect when the water liquid is sprayed, improving the spraying and filtering effect on the waste gas and increasing the waste gas filtering efficiency.

[0034] In this embodiment, as Figure 1 and Figure 5 shown, the connecting rod 303 and the spring 304 form an elastic structure. Through this design, the device can be quickly opened and closed, facilitating the staff to complete the work easily and effectively cleaning the inner wall of the device and the activated carbon filter layer, increasing the subsequent waste gas filtering efficiency and effect.

[0035] In this embodiment, as Figure 1 and Figure 6 shown, fixed rods are fixedly connected to both sides of the bottom of the filter tank 401. Through this design, the fixed rods at the bottom of the filter tank 401 can slide along with the filter tank 401, enabling the filter tank 401 to be easily and quickly extracted, replacing the original process of fixing with bolts and nuts, which was difficult to disassemble, reducing the labor cost and the required time, and facilitating the staff to clean it easily.

[0036] In this embodiment, as Figure 1 and Figure 6 shown, the height of the pull ring 405 is lower than that of the filter tank 401. Through this design, the filter tank 401 will not be affected during the pulling process, and the filter screen 404 can be extracted through the pull ring 405 for cleaning, increasing the subsequent waste gas filtering effect.

[0037] Usage method and advantages of the present utility model: For this quick-disassembly waste gas filtering device, during use, the working process is as follows:

[0038] As Figure 1 、 Figure 2 、 Figure 3 、 Figure 4, Figure 5 and Figure 6 As shown in Figure 5 and Figure 6 , first, turn on the second blower 104. The waste gas will enter the housing 101 through the intake pipe 105. Pour clean water source into the second water inlet pipe 206 through the water inlet pipe 102. The water liquid will enter the U-shaped pipe 204 and spray out from the spray head 205 to spray the waste gas. Then turn on the first blower 103. The gas after spray filtration will be further filtered through the activated carbon filter layer and discharged through the first blower 103. The water liquid after spraying will collect and filter some impurities and dust through the filter screen 404. Thus, the water liquid filtered through the filter screen 404 will be filtered into clean water liquid and fall down. Turn on the water pump 202. The filtered water liquid will be discharged into the first water inlet pipe 203 through the outlet pipe 201 and flow into the U-shaped pipe 204, and then spray out from the spray head 205 to perform cyclic spraying work. After the waste gas filtration work is completed, pull the handle 302 to contract the spring 304, so that the connecting rod 303 disengages from the slot of the fixed block. At this time, the cover plate 107 can be opened to facilitate the cleaning work of the inner wall of the device and the activated carbon filter layer. Pull the handle 402, and the filter tank 401 will be pulled out to facilitate the cleaning work of the inner wall of the filter tank 401. Pull the pull ring 405 again to disengage the filter screen 404 from the filter tank 401 to facilitate the cleaning work of the filter screen 404.

[0039] The above shows and describes the basic principles, main features and advantages of the present utility model. Those skilled in the art of this industry should understand that the present utility model is not limited by the above embodiments.
