Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-5 The haze exhaust gas treatment equipment shown includes a frame 1, a scraper 11, and a lifting drive mechanism. A fixed frame 9 is fixedly connected to the inner cavity of the frame 1. A primary filter 5 is slidably connected to the inner wall of the fixed frame 9. The primary filter 5 is used to filter dust and hair. A sliding groove 20 is opened on the outer wall of the fixed frame 9. A slider 13 is slidably connected to the inner wall of the sliding groove 20. A connecting rod 10 is fixedly connected to the outer wall of the slider 13. The scraper 11 is fixedly connected to the side of the connecting rod 10 near the primary filter 5. The lifting drive mechanism is set in the inner cavity of the frame 1. The lifting drive mechanism is used to drive the slider 13 to rise and fall. When it is necessary to clean the primary filter 5, the lifting drive mechanism is activated. The lifting drive mechanism drives the slider 13 to move. The slider 13 drives the scraper 11 to move on the surface of the primary filter 5, so as to automatically scrape off the debris on the surface of the primary filter 5, prevent the primary filter 5 from clogging and rusting, and extend the service life of the primary filter 5.

[0024] On one hand, a double-layer filter 7 and a fan 6 are fixedly connected inside the frame 1. The fan 6 is located between the double-layer filter 7 and the primary filter 5. An air inlet 3 and an air outlet 8 are fixedly connected to the outer wall of the frame 1. The air inlet 3 and the air outlet 8 are symmetrically arranged. A sliding door 2 is slidably connected to the outer wall of the frame 1. The fan 6 draws air into the frame 1 through the air inlet 3. The air first passes through the primary filter 5 to filter large particles and impurities, then passes through the double-layer filter 7 to filter particulate matter such as PM2.5 and PM10, and finally is discharged from the air outlet 8, completing the air filtration work.

[0025] On the other hand, the lifting drive mechanism includes a threaded rod 12, which is rotatably connected to the inner cavity of the frame 1. A motor 4 is fixedly connected to the top of the frame 1. The threaded rod 12 is driven to the output shaft of the motor 4. The slider 13 is threadedly sleeved on the outer wall of the threaded rod 12. When the motor 4 is started, the motor 4 drives the threaded rod 12 to move the slider 13.

The motor 4 is a reciprocating servo motor.

[0026] Preferably, a first trapezoidal plate 14 is fixedly connected to the inner cavity of the frame 1, a second trapezoidal plate 15 is fixedly connected to the end of the connecting rod 10 away from the slider 13, a fixing block 21 is fixedly connected to the outer wall of the slider 13, an elastic mechanism is fixedly provided on the outer wall of the fixing block 21, the outer wall of the elastic mechanism is fixedly connected to the outer wall of the connecting rod 10, the elastic mechanism includes a spring 22, a circular rod 23 is fixedly connected to the outer wall of the fixing block 21, the spring 22 is movably sleeved on the outer wall of the circular rod 23, the connecting rod 10 is slidably connected to the outer wall of the circular rod 23, and when the connecting rod 10 moves downward, the connecting rod... 10 drives the second trapezoidal plate 15 to move, and the inclined surfaces of the first trapezoidal plate 14 and the second trapezoidal plate 15 abut against each other. The first trapezoidal plate 14 compresses the spring 22 to drive the second trapezoidal plate 15 to move. The second trapezoidal plate 15 drives the scraper 11 to move towards the square shape close to the primary filter screen 5 through the connecting rod 10 until it abuts against the primary filter screen 5. It continues to move downward to complete the purpose of scraping off the debris on the surface of the primary filter screen 5. When the first trapezoidal plate 14 and the second trapezoidal plate 15 no longer abut against each other, the spring 22 resets and drives the scraper 11 to reset, preventing the scraper 11 and the primary filter screen 5 from squeezing the debris.

[0027] In addition, the outer wall of the sliding door 2 is provided with a snap-fit ​​groove 16, and the outer wall of the frame 1 is provided with a deep groove 19. An elastic element is fixedly installed on the inner wall of the deep groove 19, and a snap-fit ​​block 17 is slidably installed on the outer wall of the elastic element.

The snap-fit ​​block 17 is slidably sleeved on the outer wall of the round rod, and the spring is sleeved on the outer wall of the round rod. When it is necessary to replace the primary filter screen 5, the worker pulls the pull rod 18. The pull rod 18 drives the snap-fit ​​block 17 to squeeze the spring, thereby canceling the snap-fit ​​between the snap-fit ​​block 17 and the snap-fit ​​groove 16. The worker can then pull the sliding door 2 to complete the purpose of disassembling the primary filter screen 5.
