The side wall of the connecting plate 706 is fixedly connected with a push rod 707, the top of the cleaning brush 702 slides in contact with the bottom of the filter screen 4, a first slide groove 8 is provided inside the processing box 1, the outer wall of the filter screen 4 is fixedly connected with a first slider 709, and the outer wall of the first slider 709 is slidably connected to the inner wall of the third spring 710, the side wall of the first slider 709 is fixedly connected with a third spring 710, and the end of the third spring 710 away from the first slider 709 is fixedly connected to the side wall of the first slide groove 8; In this embodiment, the setting machine emits oil fume pollutants containing oil smoke, fabric capillary fibers and dust particles when it is working. If the oil fume pollutants are directly discharged without being treated, the atmosphere will be polluted. The high-temperature gas contains pollutants, so the oil fume pollutants need to be filtered and treated before they can be discharged into the atmosphere through the chimney. First, the smoke inlet pipe 16 is connected to the sewage pipe of the leather base fabric setting machine. Then, when the leather base fabric setting machine is working, the high-temperature oil fume pollutants generated will enter the interior of the treatment box 1 through the smoke inlet pipe 16, and then the high-temperature gas pollutants will rise in the interior of the treatment box 1. At the same time, the sedimentation water pipe 2 is connected to an external water source, so that the external water source provides sedimentation for the sedimentation water pipe 2. The required washing water is then atomized and sprayed into the interior of the treatment box 1 through the atomizing nozzle 3. The atomized washing water then falls inside the treatment box 1. During the process, it will contact the oil fume pollutants, and can drive some oil fume particles and water-soluble pollutants to fall downward, thereby filtering the oil fume pollutants. By arranging spiral blades 13 inside the treatment box 1, the treatment time of the oil fume pollutants inside the treatment box 1 is extended, and the treatment effect of the oil fume pollutants is effectively improved. Then, the gas that continues to rise will be deeply filtered by the filter 4. By filtering the gas twice, the filtering effect is improved to ensure that the gas meets the emission standards after filtering. After the filter 4 continues to filter, a large amount of pollutants such as oil and dirt are attached and adsorbed on the filtering surface of the filter 4. When more pollutants accumulate on the filter 4, the filtering effect of the filter 4 will be affected. If the cleaning operation is not performed at this time, the accumulation of pollutants will become higher and higher, which will seriously affect the filtering effect of the filter 4 and will also clog the filter 4, so it will seriously affect the normal operation of the equipment. The output shaft 6 is driven by the driving motor 5 to rotate. The outer wall of the rotating shaft 6 penetrates and is rotatably connected to the inside of the processing box 1. The outer wall of the rotating shaft 6 penetrates and is rotatably connected to the inside of the filter 4. Then the rotating shaft 6 drives the cleaning mechanism 7 to move, so that the cleaning mechanism 7 can be cleaned. The cleaning plate 701 rotates with the rotating shaft 6 as the axis, and the cleaning plate 701 drives the cleaning brush 702 to rotate synchronously. During the process, the cleaning brush 702 slides against the filtering surface of the filter 4, thereby scraping off a large amount of pollutants adsorbed on the filter 4, thereby cleaning the filtering surface of the filter 4. At the same time, the cleaning plate 701 can drive the block 704 to rotate synchronously through the third slide groove 703. The bottom of the filter 4 is fixedly connected with a fixed rod 708. The side wall of the block 704 corresponds to the outer wall of the fixed rod 708. When the block 704 rotates to a certain position, it will contact the fixed rod 708. Due to the large elastic force of the third slide groove 703, the filter 4 can be cleaned. Due to the elastic force of the third spring 710, the outer wall of the fixing rod 708 will be squeezed during the subsequent rotation process, and then the fixing rod 708 will drive the filter screen 4 to rotate, and at the same time, the filter screen 4 will drive the first slider 709 to slide along the inner wall of the first slide groove 8, and at the same time, the third spring 710 will be compressed. When the first slider 709 slides to the other end of the first slide groove 8, the filter screen 4 will stop rotating. Then, during the squeezing process of the fixing rod 708 by the stop block 704, the stop block 704 will slide along the inner wall of the third slide groove 703, and at the same time, the second spring 705 will be compressed. When the stop block 704 slides to a certain distance, the fixing rod 70 The outer wall of the stopper 704 will slide along the inclined surface of the stopper 704, and then the stopper 704 will pass over and separate from the fixing rod 708. At this time, the stopper 704 will reset and slide by the elastic force of the third slide groove 703, and the third spring 710 will also reset by elastic force, and then the filter screen 4 will be driven to rotate in the opposite direction through the first slider 709. Since the compressed force of the third spring 710 is released instantly, the filter screen 4 will vibrate when rotating and resetting, thereby vibrating and shaking off the pollutants adsorbed on the filtering surface of the filter screen 4, further improving the cleaning effect of the filter screen 4, and the filtered pollutants will fall into the interior of the collection box 14 through the collection port 15; As described above, when the filter 4 is blocked, the output shaft 6 is driven to rotate by the driving motor 5, and then the shaft 6 drives the cleaning mechanism 7 to move, so that the cleaning plate 701 rotates with the shaft 6 as the axis, and at the same time, the cleaning plate 701 drives the cleaning brush 702 to rotate synchronously, so that the cleaning brush 702 slides on the filtering surface of the filter 4, thereby scraping off a large amount of pollutants adsorbed on the filter 4, thereby achieving the function of cleaning the filtering surface of the filter 4, and at the same time, the fixing rod 708 is squeezed by the stop block 704, thereby driving the filter 4 to rotate, and then the stop block 704 slides toward the inner wall of the third slide groove 703 to make the filter 4 rotate in the opposite direction, which can make the filter 4 vibrate, thereby vibrating and shaking off the pollutants adsorbed on the filtering surface of the filter 4, further improving the effect of cleaning the filter 4.

[0019] Embodiment 2, based on the above embodiment, the inner wall of the processing box 1 is provided with an adjusting mechanism 9, so that when cleaning, the atomizing nozzle 3 can be driven to spray the filter surface of the filter screen 4; Further, the adjustment mechanism 9 includes a mounting frame 901, and a rotating ring 902 is rotatably connected to the side wall of the mounting frame 901, a first connecting rod 903 is fixedly connected to the outer wall of the rotating ring 902, and the end of the first connecting rod 903 away from the rotating ring 902 is rotatably connected to the second connecting rod 904, the end of the second connecting rod 904 away from the first connecting rod 903 is fixedly connected to a movable ring 905, and the outer wall of the movable ring 905 is fixedly connected to a second slider 906, the outer wall of the mounting frame 901 is fixedly connected to the inner wall of the processing box 1, the outer wall of the movable ring 905 is slidably connected to the inner wall of the processing box 1, the inner wall of the processing box 1 is provided with a second slide groove 10, and the inner wall of the second slide groove 10 is fixedly connected to the slide rod 11, the bottom of the second slider 906 is fixedly connected to the first spring 12, and the end of the first spring 12 away from the second slider 906 is fixedly connected to the inner wall of the second slide groove 10, and the inner wall of the second slider 906 is slidably connected to the outer wall of the slide rod 11; In this embodiment, while the filter screen 4 is being cleaned by the cleaning brush 702, the cleaning plate 701 will simultaneously drive the push rod 707 to move via the connecting plate 706. The outer wall of the push rod 707 will slide in contact with the top of the movable ring 905. Therefore, when the push rod 707 starts to move, the inclined surface of the movable ring 905 will be squeezed. When the movable ring 905 is squeezed, the second slider 906 will be driven to slide downward along the inner wall of the second slide groove 10. During this process, the first spring 12 will be compressed. When the movable ring 905 slides downward along the inner wall of the processing box 1, the end of the first connecting rod 903 will be driven by the second connecting rod 904. When the cleaning mechanism 7 is moved downward, the first connecting rod 903 drives the rotating ring 902 to rotate, so that the spraying direction of the atomizing nozzle 3 is tilted, thereby changing the spraying direction of the atomizing nozzle 3, and then the atomizing nozzle 3 sprays the filtering surface of the filter 4, which can soften the pollutants adsorbed on the filter 4, so that the cleaning brush 702 can clean the filter 4 more cleanly, effectively improving the cleaning effect, and then when the cleaning work of the cleaning mechanism 7 is completed, the rod 707 will slide back to the lower part of the inclined surface of the movable ring 905, and then the movable ring 905 will be reset by the elastic force of the second slider 906 to rotate the atomizing nozzle 3 to a normal spraying angle; As described above, during the process of cleaning the filter 4, the cleaning plate 701 drives the push rod 707 to move synchronously, and then the push rod 707 will squeeze the top inclined surface of the movable ring 905, so that the movable ring 905 drives the end of the first connecting rod 903 to move downward through the second connecting rod 904. At the same time, the first connecting rod 903 will drive the rotating ring 902 to rotate, thereby changing the spraying direction of the atomizing nozzle 3. Then the atomizing nozzle 3 will spray the filtering surface of the filter 4, which can soften the pollutants adsorbed on the filter 4, so that the cleaning brush 702 can clean the filter 4 more thoroughly, effectively improving the cleaning effect.

[0020] Working principle: by connecting the smoke inlet pipe 16 to the sewage pipe of the leather base fabric forming machine, when the leather base fabric forming machine is working, the high-temperature oil fume pollutants generated will enter the interior of the treatment box 1 through the smoke inlet pipe 16, and then the high-temperature gas pollutants will rise in the interior of the treatment box 1, and at the same time, by connecting the sedimentation water pipe 2 with an external water source, the external water source provides the sedimentation water pipe 2 with the washing water required for sedimentation, and then the washing water is atomized and sprayed into the interior of the treatment box 1 through the atomizing nozzle 3, and then the atomized washing water will fall in the interior of the treatment box 1, and will contact the oil fume pollutants in the process, which can drive some oil fume particles and water-soluble pollutants to fall downward, so as to achieve the effect of filtering the oil fume pollutants, and by arranging the spiral blades 13 in the interior of the treatment box 1, the treatment time of the oil fume pollutants in the treatment box 1 is extended, which effectively improves the treatment effect of the oil fume pollutants, and then the gas that continues to rise will be deeply filtered by the filter 4; After the filter 4 continues to filter, a large amount of pollutants such as oil and dirt are attached and adsorbed on the filtering surface of the filter 4. When more pollutants accumulate on the filter 4, the filtering effect of the filter 4 will be affected. If the cleaning operation is not performed at this time, the accumulation of pollutants will become higher and higher, which will seriously affect the filtering effect of the filter 4 and will also clog the filter 4, so it will seriously affect the normal operation of the equipment. The output shaft 6 is driven by the driving motor 5 to rotate, and then the shaft 6 will drive the cleaning mechanism 7 to move, so that the cleaning plate 701 rotates with the shaft 6 as the axis, and the cleaning The plate 701 will drive the cleaning brush 702 to rotate synchronously. During the process, the cleaning brush 702 will slide against the filtering surface of the filter screen 4, thereby scraping off a large amount of pollutants adsorbed on the filter screen 4, thereby cleaning the filtering surface of the filter screen 4. At the same time, the cleaning plate 701 can drive the block 704 to rotate synchronously through the third slide groove 703. When the block 704 rotates to a certain position, it will contact the fixing rod 708. Since the elastic force of the third slide groove 703 is greater than the elastic force of the third spring 710, the outer wall of the fixing rod 708 will be squeezed during the subsequent rotation process, and then fixed. The rod 708 will drive the filter screen 4 to rotate, and the filter screen 4 will drive the first slider 709 to slide along the inner wall of the first slide groove 8, and at the same time compress the third spring 710. When the first slider 709 slides to the other end of the first slide groove 8, the filter screen 4 will stop rotating. Then, during the squeezing process of the stop block 704 on the fixed rod 708, the stop block 704 will slide along the inner wall of the third slide groove 703, and at the same time compress the second spring 705. When the stop block 704 slides to a certain distance, the outer wall of the fixed rod 708 will slide along the inclined surface of the stop block 704. Then the stop block 704 will pass over and disengage from the fixing rod 708. At this time, the stop block 704 will slide back to its original position through the elastic force of the third slide groove 703. At the same time, the third spring 710 will also be reset by elastic force. Then, the filter screen 4 will be driven to rotate in the opposite direction through the first slider 709. Since the compressed force of the third spring 710 is released instantly, the filter screen 4 will vibrate during the rotation and reset, thereby vibrating and shaking off the pollutants adsorbed on the filtering surface of the filter screen 4, thereby further improving the cleaning effect of the filter screen 4. The filtered pollutants will fall into the interior of the collection box 14 through the collection port 15.
