After the first frame 6 and the second frame 8 are separated from the surface, the first slot 3 and the third slot 5 are still blocked, so that the connecting pipe 1 will not leak. Similarly, when the third frame 10 is separated from the second slot 4, the end of the third frame 10 close to the connecting pipe 1 is also always clamped inside the second slot 4.

[0027] A first column 7 is fixedly installed on one end of the first frame 6 close to the driving mechanism 28, a second column 9 is fixedly installed on one end of the second frame 8 close to the driving mechanism 28, and a third column 11 is fixedly installed on one end of the third frame 10 close to the driving mechanism 28, so that the driving mechanism 28 can control the first frame 6, the second frame 8 and the third frame 10 respectively through the first column 7, the second column 9 and the third column 11.

[0028] A groove is provided at the top of the third frame 10, and the filter plate 12 is installed in the positioning groove 13 on the surface of the third frame 10 through the groove. By setting the groove, the staff can directly plug the filter plate 12 into the positioning groove 13 on the surface of the third frame 10, and the installation is convenient and quick.

[0029] The bottom of the first column 7 and the second column 9 are both provided with a movable groove 20, and an arc groove 21 is provided above the movable groove 20.

The surface of the guide column 23 is provided with an L-shaped strip 24, and the L-shaped strip 24 is at the bottom of the positioning groove 13. When the plug-in When the bar 25 moves toward the inside of the movable groove 20, the rack 26 drives the gear 22 to rotate, and the gear 22 drives the guide column 23 to rotate. The L-shaped bar 24 will appear to be in a tilted state, and the distance between the L-shaped bar 24 and the positioning groove 13 will be expanded. At this time, the staff can insert the bottom of the filter plate 12 between the L-shaped bar 24 and the positioning groove 13, and then move the plug-in bar 25 toward the outside of the movable groove 20, the rack 26 drives the gear 22 to rotate, and the gear 22 drives the guide column 23 to rotate, and the L-shaped bar 24 will clamp the bottom of the filter plate 12, so that the filter plate 12 is fixedly installed in the positioning groove 13.

[0030] Two positioning boxes 15 are symmetrically installed inside the installation frame 2. The two positioning boxes 15 cooperate with the first column 7 and the second column 9 respectively. An inner groove 16 is arranged inside the positioning box 15. A first path groove 17 is opened on the surface of the inner groove 16. The first path groove 17 includes a first straight groove 18 and a first inclined groove 19. The first straight groove 18 is connected to the first inclined groove 19. The first straight groove 18 is close to the connecting pipe 1. A protrusion 27 is fixedly installed at one end of the plug-in strip 25 on the outside of the movable groove 20. The bottom of the protrusion 27 is slidably installed in the first path groove 17. When the first column 7 and the second column 9 move into the installation frame 2, the protrusion 27 will move along the first straight groove 18 to the first inclined groove 19. When the protrusion 27 moves into the first inclined groove 19, the plug-in strip 25 will move into the movable groove 20 as a whole. Therefore, when the first column 7 and the second column 9 are recovered to the inside of the installation frame 2, the L-shaped strip 24 will be in a tilted state, which is convenient for the staff to install and disassemble the filter plate 12.

[0031] The driving mechanism 28 includes a pushing block 29, which is slidably arranged in the middle of the installation frame 2. A flat plate 30 is arranged on the top of the pushing block 29. Two second path grooves 31 are symmetrically arranged on the surface of the flat plate 30. The second path groove 31 includes a second straight groove 32 and a second inclined groove 33. The second straight groove 32 is connected to the second inclined groove 33. The second straight groove 32 is close to the connecting pipe 1. The two second path grooves 31 are respectively matched with the first column 7 and the second column 9. The top of the first column 7 and the second column 9 are both provided with a pin shaft. Sliding protrusions are slidably arranged inside the two second path grooves 31. A connecting rod 34 is connected between the middle part of the sliding protrusion and the top of the pin shaft through a rotating shaft. A linear guide groove 38 is arranged on the top of the inner wall of the installation frame 2. The top of the sliding protrusion is slidably arranged in the linear guide groove 38. The linear guide groove 38 is linear and is opened at the center of the top of the inner cavity of the installation frame 2. When the pushing block 29 drives the flat plate 30 to continuously move toward the connecting pipe 1, the driving mechanism 28 includes a pushing block 29, which is slidably arranged in the middle part of the sliding protrusion and the top of the pin shaft. When the connecting pipe 1 approaches, the bottom of the sliding protrusion will gradually slide from the second linear groove 32 to the second inclined groove 33, and the movement of the second inclined groove 33 has a certain squeezing force on the bottom of the sliding protrusion, and the linear guide groove 38 has a limiting function on the connecting rod 34, ensuring that the distance between the sliding protrusion and the connecting pipe 1 will not change, so that when the second inclined groove 33 squeezes the bottom of the sliding protrusion, the top of the sliding protrusion will move in the linear guide groove 38, and when the pushing block 29 moves as a whole toward the connecting pipe 1, the second path groove 31 has a guiding function for the sliding protrusion, and when the sliding protrusion slides inside the second inclined groove 33, when the plate 30 moves toward the direction of the connecting pipe 1, the sliding protrusion will gradually move toward the middle of the plate 30, and the connecting rod 34 at one end of the sliding protrusion will move toward the middle of the plate 30, and the connecting rod 34 at one end of the pin shaft will move toward the inside of the mounting frame 2, thereby realizing the recovery of the first frame 6 and the second frame 8 into the mounting frame 2.

[0032] A contraction groove 35 is provided inside the push block 29, and a guide rod 36 is movably provided inside the contraction groove 35. The surface of the guide rod 36 passes through the push block 29, and the end of the guide rod 36 is fixedly connected to the third column 11. A spring 37 is provided on the surface of the guide rod 36 between the third column 11 and the push block 29. A cylinder is provided on the outside of the mounting frame 2, and the output end of the cylinder is connected to the push block 29. The cylinder can drive the push block 29 to move inside the mounting frame 2. When the push block 29 moves toward the connecting pipe 1 as a whole, the third frame 10 will be inserted into the second slot 4 as a whole, and then the push block 29 will continue to move toward the connecting pipe 1. Since the position of the third frame 10 is fixed, the movement of the push block 29 toward the connecting pipe 1 will generate pressure on the spring 37, causing the spring 37 to contract, and the guide rod 36 will contract into the contraction groove 35.

[0033] Working principle: First, when the cylinder drives the push block 29 to move toward the connecting pipe 1 as a whole, the third frame 10 will be inserted into the second slot 4 as a whole. At this time, the sliding protrusion slides in the second linear slot 32, and then the push block 29 continues to move toward the connecting pipe 1. Since the position of the third frame 10 is fixed, the push block 29 moves toward the connecting pipe 1, which will generate pressure on the spring 37, causing the spring 37 to shrink, and the guide rod 36 will shrink into the shrinkage slot 35. At this time, the sliding protrusion slides in the second inclined slot 33, and the sliding protrusion will gradually move toward the middle of the plate 30, and the connecting rod 34 at one end of the sliding protrusion will move toward the middle of the plate 30, and the connecting rod 34 at one end of the pin shaft will move toward the inside of the installation frame 2, thereby realizing the recovery of the first frame 6 and the second frame 8 into the installation frame 2, and then in the process of the first column 7 and the second column 9 moving toward the inside of the installation frame 2, the boss 27 will move along the first linear slot 18 to the first inclined slot 19. When the boss 27 moves to the first inclined slot 19, the plug The strip 25 as a whole will move toward the inside of the movable groove 20, so that when the first column 7 and the second column 9 are recovered into the installation frame 2, the rack 26 drives the gear 22 to rotate, and the gear 22 drives the guide column 23 to rotate, and the L-shaped strip 24 will be in an inclined state, and the distance between the L-shaped strip 24 and the positioning groove 13 will be expanded. At this time, it is convenient for the staff to install and disassemble the filter plate 12. In this process, the third frame 10 will first filter the gas inside the connecting pipe 1, and then the first frame 6 and the second frame 8 will move into the installation frame 2. Finally, after the filter plates 12 on the surfaces of the first frame 6 and the second frame 8 are replaced, the cylinder drives the push block 29 to be recovered. At this time, the elastic force of the spring 37 will fix the third frame 10 inside the second slot 4, and the sliding protrusion will push the first frame 6 and the second frame 8 into the first slot 3 and the third slot 5 respectively during the sliding process inside the second inclined slot 33, and then the push block 29 will continue to be recovered, and the third frame 10 will be detached from the second slot 4 and recovered into the installation frame 2.
