[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1-3 , the present invention provides a technical solution: a high-performance pneumatic diaphragm pump, including an air valve assembly 1, a liquid outlet 2, an air chamber 3 and an infusion tube 4. Both ends of the air valve assembly 1 are fixedly connected with an air chamber 3, and the side surface of the air chamber 3 is fixedly connected with a liquid outlet 2 and an infusion tube 4 through pipelines respectively. One side surface of the infusion tube 4 is fixedly connected with a liquid inlet tube 5, and two groups of support tubes 503 are fixedly connected to the side surface of the liquid inlet tube 5. The upper end of the support tube 503 is fixedly connected with a filter tube 8, and a filter cartridge 801 is installed inside the filter tube 8. A screw 9 is arranged inside the filter cartridge 801. A number of moving blocks 10 are sleeved on the side surface of the screw 9, and brushes 1002 are fixedly connected to both side surfaces of the number of moving blocks 10. The inner side surface of the moving block 10 is slidably connected to the side surface of the screw 9 through a limiting mechanism. One end of the filter tube 8 is fixedly installed with a plugging tube 7, and a plugging mechanism is arranged inside the plugging tube 7. A scraping mechanism is arranged at one end of the screw 9, and the other end of the screw 9 passes through the plugging mechanism inside the plugging tube 7 and is fixedly connected with a servo motor 6 through the plugging tube 7. A discharge tube 701 is fixedly connected to the side surface of the plugging tube 7. A cover plate 802 is installed at the other end of the filter tube 8.

[0020] As a technical optimization scheme of the present invention, the limiting mechanism includes a slide groove 901, and the slide groove 901 is located on the side surface of the screw 9. A slider is slidably connected inside the slide groove 901, and the slider is fixedly connected to the inner side surface of the moving block 10, which can limit the moving block 10, so that the moving block 10 rotates with the rotation of the screw 9. Therefore, the inner wall of the filter cartridge 801 can be cleaned by rotation, improving the cleaning effect on impurities.

[0021] As a technical optimization solution of the present utility model, the scraping mechanism includes a scraping plate 902, and the scraping plate 902 is threadedly connected to the side surface of the screw rod 9. A limiting slider 903 is fixedly connected to the side surface of the scraping plate 902, and one side surface of the limiting slider 903 is slidably connected to the inner surface of the filter cylinder 801. The impurities inside the filter cylinder 801 can be scraped by the scraping plate 902, further improving the cleaning effect on the inner wall of the filter cylinder 801. And the scraping plate 902 can be limited by the limiting slider 903 to prevent the scraping plate 902 from rotating with the screw rod 9 and causing the scraping plate 902 to be unable to move.

[0022] As a technical optimization solution of the present utility model, a return spring 1001 is arranged inside the moving block 10, and the return spring 1001 is sleeved on the side surface of the screw rod 9. Both ends of the return spring 1001 are fixedly connected to the opposite surfaces of the adjacent moving blocks 10, which can further limit the moving block 10. When the scraping plate 902 returns to its original position, it can push the moving block 10 back to its original position for the next cleaning.

[0023] As a technical optimization solution of the present utility model, the blocking mechanism includes a blocking plate 702, and the blocking plate 702 is fixedly connected to the screw rod 9. A limiting block 703 is fixedly connected to the side surface of the blocking plate 702, and the limiting block 703 is slidably connected to the inner wall of the blocking pipe 7 through a first chute. The blocking plate 702 can be moved by the screw rod 9, and when the blocking plate 702 moves to one end of the discharge pipe 701, the impurities inside the filter pipe 8 can be discharged through the discharge pipe 701. When the blocking plate 702 moves to the other end of the blocking pipe 7, the discharge pipe 701 can be blocked.

[0024] As a technical optimization solution of the present utility model, a valve II 502 is installed on the support pipe 503, and a valve I 501 is fixedly connected to the side surface of the liquid inlet pipe 5, and the valve I 501 is located between the two support pipes 503.

[0025] When the utility model is in use, first close the valve I 501 installed on the side surface of the liquid inlet pipe 5, and at the same time open the valve II 502 on the side surface of the support pipe 503. At this time, the liquid with impurities transported by the diaphragm pump will pass through the inside of the filter pipe 8, and the filter cartridge 801 inside the filter pipe 8 will filter the impurities in the liquid, and then be transported to the designated place through the diaphragm pump. Therefore, it avoids the accumulation of impurities in the liquid adhering to the inside of the air chamber 3 and improves the performance of the diaphragm pump in transporting liquid containing impurities. When there are more impurities in the filter cartridge 801, close the valve II 502 on the side surface of the support pipe 503 at this time, and start the servo motor 6 at one end of the screw 9. Therefore, the servo motor 6 will drive the screw 9 to rotate, and at this time, the scraper 902 and the plugging plate 702 on the side surface of the screw 9 will move towards the other end of the screw 9. At the same time, the moving block 10 on the side surface of the screw 9 will rotate with the screw 9. Therefore, the brush 1002 on the side surface of the moving block 10 will brush the inner wall of the filter pipe 8 and move towards the other end of the screw 9 under the push of the scraper 902. When the plugging plate 702 moves past the discharge pipe 701, the impurities and part of the liquid inside the filter cartridge 801 will be discharged from the discharge pipe 701 to the inside of the plugging pipe 7 and the filter pipe 8, and then it can be used continuously.
