[0019] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0020] Please see Figures 1-3 A dust removal device for cement production includes a dust collection box 1, with an inlet pipe 2 and an outlet pipe 3 installed at both ends of the dust collection box 1, and the outlet pipe 3 connected to an air pump 24. The dust collection box 1 contains two symmetrically distributed dust collection channels 4, each connected at both ends to the inlet pipe 2 and the outlet pipe 3, respectively. The device also includes:

[0021] Mounting plate 5, mounting bracket 6 is mounted on mounting plate 5, filter screen 7 is installed inside mounting bracket 6, and mounting grooves 23 that cooperate with mounting bracket 6 are opened on both sides of the dust collection box 1.

[0022] A sealing mechanism is installed inside the dust collection box 1 and is used to seal the dust collection channel 4 where the filter screen 7 needs to be replaced.

[0023] A limiting mechanism is provided on both sides inside the dust collection box 1 to limit and fix the mounting plate 5 in place.

[0024] By activating the air pump 24, the air inlet pipe 2 generates suction force, drawing dust-laden gas from the outside into one of the dust removal channels 4. The gas is then filtered through the filter screen 7 on the mounting frame 6, and discharged from the outlet pipe 3. When the filter screen 7 on the mounting frame 6 needs to be replaced, the sealing mechanism will block the dust removal channel 4 where the filter screen 7 needs to be replaced, while opening the other dust removal channel 4. This ensures that the dust removal and filtration of cement production dust is not affected while the filter screen 7 is being replaced. Furthermore, the limiting mechanism will release the limit on the mounting plate 5, allowing the mounting frame 6 to be pulled out for filter screen 7 replacement. The replacement is convenient and the effect is excellent.

[0025] In one embodiment, the sealing mechanism includes a sealing frame 8, both ends of which are U-shaped and contact the two dust removal channels 4. The sealing frame 8 is connected to a movable component.

[0026] The moving part includes sliders 9 installed at both ends of the middle part of the sealing frame 8. A limiting rod is installed in the dust collection box 1 and located in the middle of the two dust collection channels 4, which is slidably connected to one of the sliders 9. The other slider 9 is threadedly connected to a threaded rod 11. The threaded rod 11 is rotatably arranged in the middle of the dust collection box 1 and is connected to a motor 12 installed in the dust collection box 1.

[0027] In the initial state, one end of the baffle 8 is placed inside one of the dust removal channels 4 and blocks that channel 4, while the other end of the baffle 8 does not block the other dust removal channel 4. This allows the dust-laden gas entering from the air inlet pipe 2 to flow through only one of the dust removal channels 4, making it convenient to replace the filter screen 7 on the mounting bracket 6. When the filter screen 7 needs to be replaced, the motor 12 can be started by the external controller. The motor 12 drives the screw to rotate, thereby moving the slider 9. This causes the baffle 8 to slide towards the dust removal channel 4 where the filter screen 7 needs to be replaced, until the baffle 8 completely blocks the dust removal channel 4. The baffle 8 will then seal off the area where the mounting bracket 6 is located, while the other dust removal channel 4 will open to allow gas to continue to enter for dust removal and filtration.

[0028] In one embodiment, the limiting mechanism includes sliding cavities 13 on both sides of the dust collection box 1. A top rod 15 is slidably disposed in the sliding cavity 13. A spring 14 connected to the top rod 15 is disposed in the sliding cavity 13. The top rod 15 is connected to a support rod 20 through a transmission component. A locking block 21 is installed at the bottom of the support rod 20. The mounting plate 5 has slots 22 at both ends that cooperate with the locking block 21.

[0029] The transmission component includes a movable cavity 16 located inside the dust collection box 1 and on one side of the sliding cavity 13. A movable block 17 connected to the support rod 20 is slidably disposed inside the movable cavity 16. The top rod 15 passes through the movable block 17, and sliding columns 19 are installed at both ends of the top rod 15. Inclined grooves 18 that are slidably connected to the sliding columns 19 are opened on both sides of the movable block 17.

[0030] As the sealing frame 8 slides towards the dust removal channel 4 where the filter 7 needs to be replaced, until the sealing frame 8 completely blocks the dust removal channel 4, the sealing frame 8 will push the top rod 15, causing the top rod 15 to be pushed into the sliding cavity 13. This drives the movable block 17 to slide upward along the movable groove through the sliding column 19 on the top rod 15 and the inclined grooves 18 on both sides of the movable block 17. This causes the locking block 21 to rise through the support rod 20, causing the locking block 21 to exit the locking groove 22 of the mounting plate 5. At this time, the mounting bracket 6 can be pulled out from the mounting groove 23 by pulling the mounting plate 5, which facilitates the replacement of the filter 7. After the filter 7 is installed, the mounting bracket 6 is inserted into the mounting groove 23. When the dust removal channel 4 on this side needs to be used, the sealing frame 8 will open the dust removal channel 4 on this side, and at the same time, the locking block 21 will re-lock into the locking groove 22, thus completing the automatic limiting and fixing of the mounting plate 5.

[0031] The working principle of this utility model is as follows: by starting the air pump 24, the air inlet pipe 2 generates suction force, and draws the dust-laden gas from the outside into one of the dust removal channels 4. The gas is then filtered by the filter screen 7 on the mounting frame 6, and the filtered gas is discharged from the air outlet pipe 3. When the filter screen 7 on the mounting frame 6 needs to be replaced, the sealing mechanism will block the dust removal channel 4 where the filter screen 7 needs to be replaced, while opening the other dust removal channel 4. Thus, the dust removal and filtration of cement production dust can be carried out without affecting the replacement of the filter screen 7. In addition, the limiting mechanism will release the limit on the mounting plate 5. At this time, the mounting frame 6 can be pulled out to replace the filter screen 7. The replacement is more convenient and the effect is better.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0033] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
