A slider is slidably fitted inside the sliding sleeve, and the slider is fixed to the sliding sleeve by screws. A cylindrical filter element is fixedly connected to the slider, and the end of the filter element passes through the housing and extends into the guide tube. The end of the guide tube is connected to an air extraction fan. A grooved plate is horizontally fixed inside the housing, and a scraper is slidably fitted inside the grooved plate. A spring is provided inside the grooved plate, and the spring applies elastic force to the scraper to make the scraper abut against the surface of the filter element.
[0007] Preferably, a wedge-shaped notch is cut off at one end of the scraper.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0021] Reference Figure 1An explosion-proof cartridge dust collector includes a housing 1. Multiple sliding sleeves 5 are rotatably mounted on one side of the housing 1, and the multiple sliding sleeves 5 are located on the same circumference. Multiple guide tubes 10 are fixedly connected to the other side of the housing 1, and the positions of the guide tubes 10 correspond to the sliding sleeves 5. A ring gear 6 is fixedly connected to the outer wall of the sliding sleeves 5. A main shaft 3 is rotatably mounted on the outer wall of the housing 1. A central gear 4 is fixedly connected to the shaft of the main shaft 3, and the central gear 4 matches the ring gear 6.
[0022] The main shaft 3 drives the central gear 4 to rotate as the power shaft. When the central gear 4 rotates, it drives the ring gear 6 to rotate. When the ring gear 6 rotates, it drives the sliding sleeve 5 to rotate.
[0023] like Figure 2 and Figure 4 As shown, a slider 7 is slidably fitted inside the sliding sleeve 5. The slider 7 is fixed to the sliding sleeve 5 by a screw 8. A cylindrical filter element 9 is fixedly attached to the slider 7. The end of the filter element 9 passes through the housing 1 and extends into the conduit 10. The filter element 9 and the conduit 10 are slidably fitted. The end of the conduit 10 is connected to the vacuum pump 11. A groove plate 14 is horizontally fixed inside the housing 1. A scraper 12 is slidably fitted inside the groove plate 14. A wedge-shaped notch is cut off at one end of the scraper 12. A spring 13 is provided inside the groove plate 14. The spring 13 is always in a compressed state. The spring 13 applies elastic force to the scraper 12 so that the scraper 12 abuts against the surface of the filter element 9.
[0024] The slider 7 and the sliding sleeve 5 are detachably connected by screws 8. The slider 7 can be easily installed into or removed from the sliding sleeve 5, which makes it convenient for users to install and remove the filter element 9 on the slider 7.
[0025] During the rotation of the sliding sleeve 5, the slider 7 will rotate, and the rotation of the slider 7 will drive the filter element 9 to rotate. As the scraper 12 is pressed against the surface of the filter element 9 by the elastic force of the spring 13, the scraper 12 will clean the dust and impurities attached to the surface of the filter element 9 during the rotation of the filter element 9, thereby preventing the filter element 9 from becoming clogged and causing the filtration effect to deteriorate.
[0026] like Figure 3 and Figure 4 As shown, a discharge pipe 15 is fixedly connected to the bottom of the housing 1. A wedge-shaped collection groove 16 is opened at the top of the discharge pipe 15 to collect the impurities scraped off by the scraper 12 into the discharge pipe 15. A motor 17 is fixedly connected to one end of the discharge pipe 15, and a waste collection shell 19 is fixedly connected to the other end of the discharge pipe 15. A discharge screw 18 is fixedly connected to the output shaft of the motor 17 to transport the impurities in the discharge pipe 15 into the waste collection shell 19. A discharge valve 20 is provided at the bottom of the waste collection shell 19.
[0027] The impurities and dust scraped off the filter element 9 by the scraper 12 will fall into the wedge-shaped collection trough 16 under the action of gravity, and then be collected in the collection trough 16 and flow into the discharge pipe 15 at the bottom.
[0028] After the motor 17 starts, it will drive the discharge screw 18 to rotate. The discharge screw 18 will transport the impurities and dust in the discharge pipe 15 to the waste collection shell 19. The staff can open the discharge valve 20 regularly to discharge the impurities and dust in the waste collection shell 19.
[0029] Working principle:
[0030] When this device is working, the air pump 11 draws outside air into the inside of the housing 1 through the air inlet pipe 2 at the top of the housing 1. The air is then filtered by the filter element 9 and discharged, thereby achieving the purpose of removing impurities.
[0031] During the above operation, the main shaft 3 drives the central gear 4 to rotate as the power shaft. When the central gear 4 rotates, it drives the ring gear 6 to rotate. When the ring gear 6 rotates, it drives the sliding sleeve 5 to rotate. During the rotation of the sliding sleeve 5, it drives the slider 7 to rotate. The rotation of the slider 7 drives the filter element 9 to rotate. Since the scraper 12 is pressed against the surface of the filter element 9 under the elastic force of the spring 13, the scraper 12 cleans the dust and impurities attached to the surface of the filter element 9 during the rotation of the filter element 9, thereby preventing the filter element 9 from becoming clogged and causing the filtration effect to deteriorate. The impurities and dust scraped off from the filter element 9 by the scraper 12 will fall into the wedge-shaped collection trough 16 under the action of gravity. In the collection trough 16, they are collected and flow into the discharge pipe 15 at the bottom.
[0032] Finally, start the motor 17, which drives the discharge screw 18 to rotate. The discharge screw 18 will transport the impurities and dust in the discharge pipe 15 to the waste collection shell 19. The staff can periodically open the discharge valve 20 to discharge the impurities and dust in the waste collection shell 19.
[0033] Compared with the prior art, this application uses a scraper 12 to abut against the rotating filter element 9 to clean the impurities and dust adhering to the surface of the filter element 9, thereby preventing the filtration effect from deteriorating due to the coverage of impurities and dust on the surface of the filter element 9.
[0034] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
