[0025] See also Figure 3-4The dust scraping assembly 9 includes a chassis 91, which is fixedly connected to the top of the purification box 1 and is located between the two movable cylinders 61. A motor 92 is fixedly connected inside the chassis 91. The motor 92 is a three-phase asynchronous motor, and the output end can be adjusted for forward and reverse rotation.

[0026] Specific implementation method: The dust to be filtered is transported to the interior of the purification box 1 together with the air through a conveying pipe 2 and filtered through the dust filter screen 5 on the sealing frame 4. When the dust on one side of the dust filter screen 5 accumulates too much and affects the filtering efficiency, the motor 92 inside the dust scraping assembly 9 can be started, and the output end of the motor 92 can rotate forward and reversely, thereby driving the driving screw 93 to rotate forward and reverse, and then driving the scraper 94 to scrape up and down inside the purification box 1 and on one side of the dust filter screen 5.

When the scraper 94 moves upward, it resists the bottom of the sealing plate 65 inside an elastic reset assembly 6 through two push plates 96 and pushes the sealing plate 65 upward. While the sealing plate 65 moves upward, it drives the threaded sleeve 67 to move upward. The threaded sleeve 67 rotates while the rod surface of the driving screw 93 moves up. While the sealing plate 65 moves up, the spring 63 inside the movable cylinder 61 is squeezed through the movable rod 64 and the limit block 62. When When the scraper 94 moves downward, it pushes the sealing plate 65 inside the lower elastic reset assembly 6 to move downward and squeezes the lower spring 63. When the scraper 94 scrapes the dust on the dust filter 5 and moves upward, the dust can be moved to the dust hopper 3, and the external blower is started. The wind force delivered by an air inlet pipe 8 transports the dust on the top of the scraper 94 to the dust hopper 3 and the sewage pipe 7 in turn, and the dust is discharged through the sewage pipe 7. When the scraper 94 moves downward, the scraped dust is transported to another dust collector. At the air inlet of the hopper 3, the dust is transported out in the same way by a blower, which is convenient for quick cleaning of the dust filter 5 without disassembling the purification box 1, so as to facilitate the rapid recycling of the internal dust filter, effectively improving the working efficiency of the dust circulation purification equipment. When the scraper 94 moves back and forth, the sealing plate 65 that is not under pressure can move and reset with the rebound force of the spring 63, thereby ensuring the sealing barrier between the dust conveying channel inside the purification box 1 and the two dust collecting hoppers 3, and ensuring normal dust filtering.
