Technical Field
[0001] This utility model relates to the field of waste gas treatment technology, specifically to a waste gas filtration device that facilitates cleaning of the filter screen. Background Technology
[0002] Exhaust gas filtration devices are equipment used for exhaust gas emission and filtration. They use specific filter elements or media to capture pollutants and particles in the exhaust gas, thereby reducing the pollution of the environment by the exhaust gas.
[0003] Currently, most existing exhaust gas filtration devices may lack an efficient automatic cleaning mechanism, which leads to dust accumulation on the outer wall of the screen frame and the screen holes. As the dust continues to accumulate, the filtration efficiency of the screen frame will gradually decrease, affecting the exhaust gas treatment effect. In view of this, we propose an exhaust gas filtration device that is easy to clean. Utility Model Content

[0016] (1) This exhaust gas filtration device, which is easy to clean, achieves efficient automatic cleaning of the outer wall of the screen frame and the screen holes by driving the rotating shaft, scraper and brush of the motor. The scraper effectively removes the dust attached to the outer wall of the screen frame, while the brush makes a circular motion on the inner wall of the screen frame and the screen holes, avoiding the accumulation of dust in the screen holes, thereby significantly improving the continuous filtration efficiency of the screen frame.

[0029] See also Figures 1-6 This utility model proposes a waste gas filtration device that facilitates filter cleaning, including a barrel 1. A fixing ring 12 is fixedly connected to the inner wall of the barrel 1. The fixing ring 12 is elastically connected to the screen frame 53 by a spring. An inclined plate 11 is provided below the fixing ring 12. The inclined plate 11 is penetrated by the smoke inlet pipe 3 and fixedly connected to the smoke inlet pipe 3. The lower end of the barrel 1 is provided with the smoke inlet pipe 3. The upper side wall of the barrel 1 is provided with the smoke outlet pipe 2. The upper end of the barrel 1 is provided with the water pipe 4. The water pipe 4 is fixedly connected to the spray pipe 41. The inner wall of the barrel 1 is provided with a filtration mechanism.
[0030] In an embodiment of this utility model, in order to filter the exhaust gas, the filtration mechanism specifically includes a motor 51, which is fixedly connected to the outer wall of the barrel 1. A rotating shaft 52 is fixedly connected to the output end of the motor 51. The rotating shaft 52 passes through the barrel 1 and is rotatably connected to the barrel 1. A rotating sleeve 54 is passed through by the rotating shaft 52 and is slidably connected to the rotating sleeve 54. The rotating sleeve 54 passes through the screen frame 53 and is rotatably connected to the screen frame 53. A scraper 55 is disposed on the outer wall of the screen frame 53. The scraper 55 is passed through by the rotating sleeve 54 and is fixedly connected to the rotating sleeve 54. A brush 56 is disposed on the inner wall of the screen frame 53. The brush 56 is passed through by the rotating sleeve 54 and is fixedly connected to the rotating sleeve 54.
[0031] Furthermore, the pivot 52 passes through the crossbar 521 and is rotatably connected to the crossbar 521. A cam 520 is provided above the crossbar 521. The cam 520 is fixedly connected to the pivot 52. The crossbar 521 has a through groove 524. A short rod 527 is slidably connected to the through groove 524. A sliding block 522 is fixedly connected to the upper end of the short rod 527. A ball 528 is fixedly connected to the lower end of the short rod 527. A rod body 523 is fixedly connected to the outer wall of the sliding block 522. The rod body 523 passes through the crossbar 521 and is slidably connected to the crossbar 521. The rod body 523 is elastically connected to the outer wall of the crossbar 521 by a spring. A hammer 525 is hinged to the crossbar 521. The hammer 525 has an inclined groove 526. The inclined groove 526 is slidably connected to the short rod 527 and the ball 528.
[0032] In this invention, during use, exhaust gas is first introduced into the barrel 1 through the inlet pipe 3. The exhaust gas then passes through the screen frame 53 and is discharged through the outlet pipe 2. As the exhaust gas passes through the screen frame 53, the screen frame 53 filters the dust in the exhaust gas, and the dust accumulates on the outer wall of the screen frame 53. Then, the motor 51 is started. When the motor 51 starts, the rotating shaft 52, fixedly connected to the output end of the motor 51, drives the scraper 55 and brush 56 to rotate. When the scraper 55 rotates, the scraper... 55 cleans the outer wall of the screen frame 53 to prevent dust from adhering to it. During this process, brush 56 moves in a circular motion on the inner wall of the screen frame 53. As brush 56 moves, it cleans the screen holes of the screen frame 53, preventing dust accumulation inside and improving the filtration efficiency of the screen frame 53. Simultaneously, cam 520, fixedly connected to the rotating shaft 52, rotates synchronously. During the rotation of cam 520... The rod 523 is compressed, causing it to move. As the rod 523 moves, the sliding block 522, fixedly connected to the rod 523, drives the short rod 527 to slide within the through groove 524. As the short rod 527 moves, the ball 528, fixedly connected to the short rod 527, slides within the inclined groove 526. During this process, the ball 528 applies a force to the hammer 525, causing it to rotate around the hinge point. As the hammer 525 rotates, it impacts the screen frame 5. 3. Striking causes the screen frame 53 to vibrate, which improves the cleaning effect of the screen frame 53. When the cam 520 disengages from the rod 523, the rod 523 returns to its original position under the elastic force of the spring. At the same time, the ball 528 applies force to the inclined groove 526, causing the hammer 525 to return to its original position. After the exhaust gas is discharged, the drain port is opened, and finally the water pipe 4 is connected to the water source. At this time, clean water will be sprayed into the tank 1 through the spray pipe 41 to clean the screen frame 53.
