[0025] The specific arrangement and function of the installation device 4 and the sealing device 5 will be described in detail below.

[0026] In this embodiment: the inner wall surface of the sealing cover 9 is provided with a mounting device 4, the mounting device 4 includes a hook 401, the hook 401 is fixedly mounted on the inner wall surface of the sealing cover 9, and two vertical plates 402 are fixedly mounted on the top surface of the filter body 2, and the surfaces of the two vertical plates 402 are rotatably connected with a rotating shaft 403, and a ring 404 is fixedly mounted between the two rotating shafts 403.

[0027] In this embodiment, the provision of the ring 404 and the hook 401 serves to facilitate the installation of the filter body 2 .

[0028] Specifically, a vertical groove 405 is formed on the surface of one of the vertical plates 402, a movable plate 406 is slidably connected inside the vertical groove 405, an insertion rod 407 is fixedly installed on the surface of the movable plate 406, and a plurality of insertion holes 408 are formed in a ring shape on the outer wall surface of one of the rotating shafts 403.

[0029] In this embodiment, the arrangement of the insertion rod 407 and the insertion hole 408 has the effect of limiting the rotation of the rotating shaft 403 .

[0030] Specifically, a rectangular plate 409 is fixedly installed on the surface of one of the vertical plates 402 , and a spring 410 is fixedly installed between the rectangular plate 409 and the movable plate 406 . The setting of the spring 410 has the effect of limiting the position of the movable plate 406 inside the vertical slot 405 .

[0031] In this embodiment: a sealing device 5 is provided on the top surface of the sealing cover 9, and the sealing device 5 includes a U-shaped rod 51, which is fixedly installed on the top surface of the sealing cover 9, and a U-shaped plate 52 is slidably connected to the surface of the U-shaped rod 51, and a threaded rod 53 is rotatably connected between the inner walls at both ends of the U-shaped plate 52, and a rotating wheel 54 is fixedly installed at one end of the threaded rod 53. When it is necessary to seal the air intake pipe 10, first slide the U-shaped plate 52 so that the U-shaped plate 52 moves on the surface of the U-shaped rod 51. The movement of the U-shaped plate 52 on the surface of the U-shaped rod 51 drives the sealing plug 58 to move. When the moving position of the sealing plug 58 is on the same vertical line as the air intake pipe 10, the rotating wheel 54 is rotated at this time. The rotation of the rotating wheel 54 drives the threaded rod 53 to rotate. The rotation of the threaded rod 53 drives the displacement bar 56 to move inside the groove 55. The displacement bar 56 moves inside the groove 55 and drives the connecting rod 57 to move. The movement of the connecting rod 57 drives the sealing plug 58 to move. The sealing plug 58 moves so that it enters the interior of the air intake pipe 10. When the sealing plug 58 is located inside the air intake pipe 10, stop rotating the rotating wheel 54. Through the cooperation of the above-mentioned structure, the sealing plug 58 can seal and block the air intake pipe 10, so that when the device is not in use, dust can be prevented from entering the interior of the casing, thereby reducing the number of times the filter body 2 is maintained in the later stage.

[0032] Specifically, a groove 55 is formed on the inner wall surface of the U-shaped plate 52 , and a displacement bar 56 is threadedly connected to the surface of the threaded rod 53 .

[0033] In this embodiment, the threaded rod 53 is provided to drive the displacement bar 56 to move inside the groove 55 .

[0034] Specifically, a connecting rod 57 is fixedly mounted on the surface of the displacement bar 56 , and a sealing plug 58 is fixedly mounted on one end of the connecting rod 57 away from the displacement bar 56 .

[0035] In this embodiment, the provision of the sealing plug 58 has the effect of sealing the intake pipe 10 .

[0036] Working principle: by setting the installation device 4, when the filter body 2 needs to be installed, the cylinder 7 is first started, and the cylinder 7 is started to drive the fixing plate 8 to move downward, and the fixing plate 8 moves upward to drive the sealing cover 9 to move upward, and the sealing cover 9 moves upward to move itself out of the inside of the installation groove 3. When the sealing cover 9 moves to a suitable height, the sliding movable plate 406 makes the movable plate 406 move inside the vertical groove 405. The movement of the movable plate 406 inside the vertical groove 405 will squeeze the spring 410, so that the spring 410 is compressed. At the same time, the movement of the movable plate 406 inside the vertical groove 405 also drives the insertion rod 407 to move, and the insertion rod 407 moves to move itself out of the inside of the socket 408, and the insertion rod 407 and the socket 408 are separated to make the rotating plate 406 move. The shaft 403 loses its limit, and the ring 404 can be rotated at this time. When the ring 404 rotates to a vertical state, the movable plate 406 is loosened, and the resilience of the spring 410 is used to reinsert the insertion rod 407 into the corresponding insertion hole 408, so as to re-limit the rotation of the rotating shaft 403. At this time, the ring 404 is hung on the hook 401, and then the cylinder 7 is started, so that the cylinder 7 drives the sealing cover 9 to be re-located inside the installation groove 3. When the sealing cover 9 is located inside the installation groove 3, the filter body 2 is also located inside the shell 1, and the installation operation of the filter body 2 is completed. Through the cooperation of the above-mentioned structure, the hook 401 and the ring 404 are used for the hanging method, which makes the later maintenance convenient and the filter body 2 easy to install and replace. When it is necessary to seal the air intake pipe 10, first slide the U-shaped plate 52 so that the U-shaped plate 52 moves on the surface of the U-shaped rod 51. The movement of the U-shaped plate 52 on the surface of the U-shaped rod 51 drives the sealing plug 58 to move. When the moving position of the sealing plug 58 is on the same vertical line as the air intake pipe 10, the rotating wheel 54 is rotated at this time. The rotation of the rotating wheel 54 drives the threaded rod 53 to rotate. The rotation of the threaded rod 53 drives the displacement bar 56 to move inside the groove 55. The displacement bar 56 moves inside the groove 55 and drives the connecting rod 57 to move. The movement of the connecting rod 57 drives the sealing plug 58 to move. The sealing plug 58 moves so that it enters the interior of the air intake pipe 10. When the sealing plug 58 is located inside the air intake pipe 10, stop rotating the rotating wheel 54. Through the cooperation of the above-mentioned structure, the sealing plug 58 can seal and block the air intake pipe 10, so that when the device is not in use, dust can be prevented from entering the interior of the casing, thereby reducing the number of times the filter body 2 is maintained in the later stage.
