[0002] In modern industrial production activities, the generation of dust is almost inevitable, especially in industries such as mining, metallurgy, chemical industry, construction and machinery manufacturing. These dusts are mainly composed of tiny solid particles. They are suspended in the air, which will not only reduce the visibility in the workshop and affect the operator's line of sight, but also cause serious pollution to the air quality. Long-term exposure to dusty environment will threaten the respiratory health of operators and may even cause occupational diseases. Therefore, the industry widely uses various dust filtration and collection equipment, such as plate and frame filters, which can effectively capture and separate dust particles in the air, thereby improving the production environment and protecting employee health.

The sealing ring 8 is conical. In the natural state, the maximum outer diameter of the sealing ring 8 fits with the inner wall of the mounting tube 4, so that the outer side of the sealing ring 8 faces the rotary vane 6. A contraction component 9 is movably connected inside the guide tube 7, and the contraction component 9 is fixedly connected to the back side of the sealing ring 8. A cleaning component 10 is provided at the bottom end of the mounting frame 1, and the cleaning components 10 are all located at the bottom end of the mounting tube 4.

[0024] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the contraction assembly 9 includes an insertion rod 901, a receiving block 902, a push rod 903 and a moving cylinder 904, one end of the insertion rod 901 is fixedly connected to the receiving block 902, the push rods 903 are distributed in a circular array, the ends of the push rods 903 close to the insertion rod 901 are movably connected to the inside of the receiving block 902, one end of the moving cylinder 904 is configured with a groove 11, the inner diameter of the groove 11 gradually decreases along the axial direction of the moving cylinder 904, the ends of the push rods 903 away from the receiving block 902 are fitted with the inner side surface of the groove 11, the front end of the insertion rod 901 is movably plugged into the tail end of the rotating shaft of the rotating blade 6, the outer side of the moving cylinder 904 is fixedly connected to a plurality of connecting rods 12, and the ends of the connecting rods 12 away from the moving cylinder 904 are fixedly connected to the connecting blocks 13, and the ends of the connecting blocks 13 away from the connecting rods 12 are movably connected through the rotating shaft. A connecting rod 14 is connected, and several patches 15 are fixedly connected to the inner side of the sealing ring 8. The movement of the patches 15 can drive the sealing ring 8 to shrink or expand as a whole. The end of the connecting rod 14 away from the connecting block 13 is movably connected to the patches 15 through a rotating shaft. The interior of the guide tube 7 is fixedly connected to a containing frame 16. The containing block 902 and the moving cylinder 904 are both movably connected to the interior of the containing frame 16. The moving cylinder 904 and the connecting rod 12 can both move inside the containing frame 16. The setting of the containing frame 16 can prevent dust from entering the interior of the containing frame 16. When the dust changes its moving direction through the rotary blades 6, clean air is discharged through the guide tube 7. The rear end of the moving cylinder 904 is fixedly connected to a reset spring 17, and the other end of the reset spring 17 is fixedly connected to the interior of the containing frame 16.

[0025] The exhaust gas is passed into the interior of the mounting tube 4, and the exhaust gas drives the rotary blade 6 to rotate. When the rotary blade 6 rotates, the large particles in the exhaust gas are thrown toward the inner wall of the mounting tube 4. As the rotary blade 6 rotates, the insertion rod 901 rotates synchronously. Under the action of centrifugal force, the push rod 903 moves outward, and the front end of the push rod 903 conflicts with the groove 11 at the front end of the moving cylinder 904, thereby pushing the moving cylinder 904 to move inside the accommodating frame 16, so that the return spring 17 is compressed and shortened, and drives the connecting rod 12 and the connecting block 13 at its end to move synchronously, so that the connecting rod 14 moves and rotates at the same time, thereby pulling the patch 15 close to the guide The outer wall of the tube 7 moves, that is, the edge of the sealing ring 8 moves toward the outer wall of the guide tube 7, so that there is a gap between the sealing ring 8 and the inner wall of the mounting tube 4, so that the dust particles pass through the sealing ring 8 along the inner wall of the mounting tube 4 and enter the interior of the mounting frame 1, and under the action of its own gravity, only when the rotary blade 6 rotates, that is, when the exhaust gas is processed, the sealing ring 8 is in a contracted state, which is conducive to the dust entering the bottom of the mounting frame 1 for collection, and when the rotary blade 6 stops rotating, the sealing ring 8 is reset, so that the dust passing through the sealing ring 8 cannot move back, thereby avoiding the backflow of dust and maintaining the flow state inside the mounting tube 4.

[0026] like Figure 1 and Figure 6 As shown, the ash cleaning component 10 includes an ash guide plate 1001, an ash accumulation trough 1002, an ash discharge pipe 1003 and an ash scraper 1004. The ash guide plate 1001 is symmetrically arranged and fixedly connected to the inner side of the mounting frame 1. The ash accumulation trough 1002 is fixedly connected to the inner side of the mounting frame 1. The bottom end of the ash guide plate 1001 is located at the edge of the ash accumulation trough 1002. The ash discharge pipe 1003 is fixedly connected to one end of the ash accumulation trough 1002, and the ash scraper 1004 is movably connected to the surface of the ash guide plate 1001 and the inner side of the ash accumulation trough 1002. A pull rod 18 is fixedly connected to one side of the scraper 1004. The pull rod 18 passes through the mounting frame 1 and is movably connected to the mounting frame 1.

[0027] Under the action of their own gravity, the dust particles fall to the bottom end of the mounting frame 1 and fall onto the ash guide plate 1001. Since the ash guide plate 1001 is inclined, the dust particles move along the ash guide plate 1001 to the inside of the ash accumulation trough 1002. When the ash accumulation trough 1002 accumulates a lot of dust, the pull rod 18 is pulled outward to drive the scraper plate 1004 to move along the ash guide plate 1001 and the ash accumulation trough 1002, and the dust on the surface of the ash guide plate 1001 is scraped off to the inside of the ash accumulation trough 1002, and the dust inside the ash accumulation trough 1002 is pushed to the ash discharge pipe 1003, so that the dust is discharged from the ash discharge pipe 1003, which is beneficial to the unified collection of dust particles and conveniently remove them from the inside of the mounting frame 1, so as to facilitate the equipment to continue the dust filtering operation.

[0028] Working principle: When in use, first, the mounting tube 4 is clamped on the panel 2, and the guide tube 7 is clamped on the back plate 3, then the mounting tube 4 is aligned with the guide tube 7 in turn, and the tail end of the rotary vane 6 is movably plugged with the front end of the plug rod 901, and the panel 2 and the back plate 3 are installed on the mounting frame 1 by bolts, and then the front end of the mounting tube 4 is connected to the ventilation pipe, so that the exhaust gas is passed into the interior of the mounting tube 4, and the exhaust gas drives the rotary vane 6 to rotate. When the rotary vane 6 rotates, the large particles in the exhaust gas are thrown to the inner wall of the mounting tube 4. With the rotation of the rotary vane 6, the plug rod 901 rotates synchronously. Under the action of centrifugal force, the push rod 903 moves outward, and the front end of the push rod 903 conflicts with the groove 11 at the front end of the moving cylinder 904, thereby pushing the moving cylinder 904 to move inside the accommodating frame 16, so that the reset spring 17 is compressed and shortened, and drives the connecting rod 12 and the connecting block 13 at its end to move synchronously, so that the connecting rod 14 moves at the same time When the dust particles are in the mounting frame 1, they rotate, thereby pulling the patch 15 to move close to the outer wall of the guide tube 7, that is, moving the edge of the sealing ring 8 toward the outer wall of the guide tube 7, so that there is a gap between the sealing ring 8 and the inner wall of the mounting tube 4, so that the dust particles pass through the sealing ring 8 along the inner wall of the mounting tube 4 and enter the interior of the mounting frame 1, and fall to the bottom of the mounting frame 1 under the action of their own gravity, and fall onto the dust guide plate 1001. Since the dust guide plate 1001 is arranged at an angle, the dust particles are This causes the dust particles to move along the ash guide plate 1001 to the inside of the ash accumulation trough 1002. When the ash accumulation trough 1002 accumulates a lot of dust, the pull rod 18 is pulled outward to drive the scraper plate 1004 to move along the ash guide plate 1001 and the ash accumulation trough 1002, so as to scrape the dust on the surface of the ash guide plate 1001 to the inside of the ash accumulation trough 1002, and push the dust inside the ash accumulation trough 1002 to the ash discharge pipe 1003, so as to discharge the dust from the ash discharge pipe 1003.
