[0021] The mounting mechanism 6 includes a support ring 601, a mounting base 602, a limiting groove 603, a movable groove 604, a reset spring 605, a limiting block 606, a steel cable 607 and a pull ring 608. The support ring 601 is fixedly connected to the inside of the filter box 1, the mounting base 602 is fixedly connected to one side of the surface of the filter box 1, a limiting groove 603 is provided on one side of the surface of the filter frame 4, a movable groove 604 is provided inside the mounting base 602, a reset spring 605 is provided inside the movable groove 604, and a reset spring 605 is provided inside the movable groove 604. One end of the spring 605 is fixedly connected to the limit block 606, one end of the limit block 606 is fixedly connected to the steel cable 607, and the other end of the steel cable 607 is fixedly connected to the pull ring 608. Through the arrangement of the support ring 601, the mounting base 602, the limit groove 603, the movable groove 604, the reset spring 605, the limit block 606, the steel cable 607 and the pull ring 608, when the filter element 504 needs to be disassembled, replaced and cleaned, the pull ring 608 can be pulled. At this time, the pull ring 608 is brought by the steel cable 607. The movable limit block 606 moves toward the inside of the movable groove 604, and the return spring 605 is compressed and deformed. When the limit block 606 is completely embedded in the inside of the movable groove 604, the filter frame 4 with the filter element 504 installed is passed through the installation base 602 so that one end of the filter frame 4 is embedded in the inside of the support ring 601, and the limit groove 603 opened on one side of the surface of the filter frame 4 is aligned with the position of the movable groove 604, and the force applied to the pull ring 608 is released. At this time, the return spring 605 The limit block 606 is deformed by rebounding to restore to its original position. At this time, one end of the limit block 606 is embedded in the movable groove 604, and the other end of the limit block 606 is embedded in the limit groove 603. Thus, the limit block 606 installs the filter frame 4 inside the filter box 1. When it needs to be removed, pull the pull ring 608 to make the limit block 606 completely embedded in the movable groove 604. At this time, the limit block 606 loses its limiting effect on the filter frame 4, so that the filter frame 4 can be removed.

[0022] Furthermore, one end of the filter frame 4 is embedded in the support ring 601, and the limiting groove 603 is consistent with the size of the movable groove 604. Through the setting of the limiting groove 603, when in use, when one end of the limiting block 606 is embedded in the movable groove 604 and the other end is embedded in the limiting groove 603, the filter frame 4 can be fixed.

[0023] Furthermore, the cross-sectional dimensions of the limit block 606 match the cross-sectional dimensions of the limit groove 603, and the steel cable 607 runs through the interior of the reset spring 605. Through the setting of the steel cable 607, when in use, the steel cable 607 can transfer the force applied to the pull ring 608 to the limit block 606 to move the limit block 606.

[0024] Furthermore, one end of the return spring 605 is fixedly connected to the mounting base 602 inside the movable groove 604. Through the setting of the return spring 605, when in use, the rebound deformation of the return spring 605 can drive the limit block 606 to return to its original position, so that a section of the limit block 606 is embedded in the limit groove 603.

[0025] Furthermore, the dust removal and filtering mechanism 5 includes an air inlet pipe 501, a dust hopper 502, a partition 503, a filter element 504, a ventilation pipe 505, a fan 506, a dust exhaust pipe 507 and an air outlet pipe 508. The side of the filter box 1 is sealed with the air inlet pipe 501, the bottom of the filter box 1 is installed with a dust hopper 502, the interior of the filter box 1 is fixedly connected with a partition 503, the interior of the filter frame 4 is installed with a filter element 504, the side of the filter box 1 is connected with a ventilation pipe 505, a fan 506 is installed on one side of the surface of the box cover 2, the bottom of the dust hopper 502 is fixedly connected with a dust exhaust pipe 507, and one end of the fan 506 is connected to the air outlet pipe 508. Through the arrangement of the air inlet pipe 501, the dust hopper 502, the partition 503, the filter element 504, the ventilation pipe 505, the fan 506, the dust exhaust pipe 507 and the air outlet pipe 508, when When it is necessary to remove dust from the air, the fan 506 can be turned on. At this time, the fan 506 exhausts air to the inside of the filter box 1 through the ventilation pipe 505. At this time, the air with dust enters the inside of the filter box 1 from the air inlet pipe 501. When the air enters the inside of the filter box 1, it is first blocked by the partition 503 to prevent the air from directly impacting the filter element 504 and affecting the service life of the filter element 504. The larger dust impurities in the air inside the filter box 1 are precipitated and fall into the dust hopper 502. Then the air is filtered by the filter element 504. The filtered air moves toward the fan 506 through the ventilation pipe 505, and then is discharged by the exhaust pipe 508 through the fan 506. When dust accumulates in the dust hopper 502, the dust exhaust pipe 507 can be opened. At this time, the dust is discharged from the inside of the filter box 1 through the dust exhaust pipe 507.

[0026] Furthermore, the partition 503 is aligned with the air inlet pipe 501 , and four groups of filter elements 504 are provided. Through the provision of the partition 503 , when in use, the partition 503 can prevent air from directly impacting the filter element 504 and affecting the service life of the filter element 504 .

[0027] Furthermore, the ventilation pipe 505 is aligned with the filter element 504, and the other end of the ventilation pipe 505 is sealed and connected to the fan 506. Through the setting of the ventilation pipe 505, when in use, the ventilation pipe 505 can draw the air filtered by the filter element 504 out from the inside of the filter box 1 and then discharge it through the exhaust pipe 508.

[0028] Working principle: first, move the filter box 1 to a suitable working position through the roller 7, and then turn on the fan 506. At this time, the fan 506 exhausts air to the inside of the filter box 1 through the ventilation pipe 505. At this time, the air with dust enters the inside of the filter box 1 from the air inlet pipe 501. When the air enters the inside of the filter box 1, it is first blocked by the partition 503 to prevent the air from directly impacting the filter element 504 and affecting the service life of the filter element 504. The larger dust impurities in the air inside the filter box 1 are precipitated and fall into the dust hopper 502. Then the air is filtered by the filter element 504. The filtered air moves toward the fan 506 through the ventilation pipe 505, and then is discharged by the exhaust pipe 508 through the fan 506. When dust accumulates in the dust hopper 502, the dust exhaust pipe 507 can be opened. At this time, the dust is discharged from the inside of the filter box 1 through the dust exhaust pipe 507. When the filter element 504 needs to be disassembled, replaced and cleaned, the pull ring 608 can be pulled. At this time, the pull ring 608 is connected to the steel cable 607. The limit block 606 is driven to move toward the inside of the movable groove 604. At this time, the return spring 605 is compressed and deformed. When the limit block 606 is completely embedded in the inside of the movable groove 604, the filter frame 4 with the filter element 504 installed is passed through the installation base 602 so that one end of the filter frame 4 is embedded in the inside of the support ring 601. At the same time, the limit groove 603 opened on one side of the surface of the filter frame 4 is aligned with the position of the movable groove 604. The force applied to the pull ring 608 is released. At this time, the return spring 605 The limit block 606 is deformed by rebounding to restore to its original position. At this time, one end of the limit block 606 is embedded in the movable groove 604, and the other end of the limit block 606 is embedded in the limit groove 603. Thus, the limit block 606 installs the filter frame 4 inside the filter box 1. When it needs to be removed, pull the pull ring 608 to make the limit block 606 completely embedded in the movable groove 604. At this time, the limit block 606 loses its limiting effect on the filter frame 4, so that the filter frame 4 can be removed.
