[0023] A multi-stage filtration type anti-corrosion environmentally friendly dust removal filter cartridge, such as Figure 1 As shown, it includes a bottom plate 1, the top of the bottom plate 1 is fixedly connected to a protective shell 2, and the inner wall of the protective shell 2 is fixedly connected to an anti-corrosion layer 3, the inner wall of the anti-corrosion layer 3 is fixedly connected to a filter layer 4, the top of the protective shell 2 is movably connected to a top plate 5, and the top of the top plate 5 is movably connected to a docking mechanism 6 for docking the protective shell 2, the inner top of the top plate 5 is fixedly connected to a mounting shell 7, and the opposite side of the top of the mounting shell 7 is fixedly connected to a clamping sleeve 8, and a clamping groove 9 is provided inside the clamping sleeve 8.

[0024] When in use, after the filter cartridge has been used for a period of time, it can be removed from the external device. At this time, the screw rod 606 can be rotated. When the screw rod 606 rotates, it will drive the lifting plate 609 to move downward. At this time, the limit plate will be restored by the tension spring 10, so that the limit plate is away from the slot 9, thereby releasing the limit. At this time, the rotating wheel 602 can be rotated, and the rotating wheel 602 will drive the transmission plate 603 to rotate through the transmission rod 601. At this time, the transmission plate 603 will drive the slide plate 604 to move through the transmission groove, so that the limit block 605 is away from the limit groove, and the connection with the protective shell 2 is released. Thereafter, the top plate 5 can be removed, and the personnel can clean the inside of the filter cartridge. When docking is required, the docking can be completed by operating the device in the direction. The docking between the top plate 5 and the protective shell 2 is completed by the transmission plate 603, the slide plate 604 and the limit block 605, which can make it more convenient for personnel to clean the inside of the cylinder, and it is also more convenient for personnel to replace or repair the filter layer 4 and the anti-corrosion layer 3, thereby reducing the inconvenience caused by personnel cleaning, thereby reducing the difficulty of personnel operation.

[0025] As shown in the figure, the docking mechanism 6 includes a transmission rod 601, a rotating wheel 602, a transmission plate 603, a slide plate 604 and a limit block 605. The bottom end of the transmission rod 601 is fixedly connected to the axis of the transmission plate 603. The top of the transmission plate 603 is provided with a transmission groove, and one side of the top of the slide plate 604 is slidably connected to the inside of the transmission groove.

The top of the protective shell 2 is provided with a limit groove, and the limit block 605 is movably connected to the inside of the limit groove. The transmission plate 603 is rotatably connected to the inside of the mounting shell 7. The top of the transmission rod 601 extends to the outside of the top plate 5 and is fixedly connected to the rotating wheel 602. The docking mechanism 6 also includes a screw 606, a limit The limiting rod 607, the spring 608 and the lifting plate 609, the lifting plate 609 is threadedly connected to the outer wall of the screw 606, the top of the spring 608 is fixedly connected to the bottom end of the lifting plate 609, the bottom end of the limiting rod 607 is movably connected to the top of the lifting plate 609, the bottom end of the spring 608 is fixedly connected to the inner bottom end of the transmission rod 601, and the screw 606 is located on the opposite side of the spring 608, the top end of the screw 606 extends to the outside of the rotating wheel 602, a plurality of limiting rods 607 are provided, and the limiting rods 607 are hinged to the outer wall of the transmission rod 601, the top end of the limiting rod 607 is movably connected to the inside of the slot 9, the screw 606 is rotatably connected to the inside of the transmission rod 601, the bottom end of the limiting rod 607 is fixedly connected to the tension spring 10, and the bottom end of the tension spring 10 is fixedly connected to the inside of the top of the lifting plate 609.

[0026] After the filter cartridge has been used for a period of time, it can be removed from the external device, and the screw rod 606 can be rotated at this time. When the screw rod 606 rotates, it will drive the lifting plate 609 to move downward. At this time, the limit plate will be restored by the tension spring 10, so that the limit plate is away from the slot 9, so as to release the limit. At this time, the rotating wheel 602 can be rotated, and the rotating wheel 602 will drive the transmission plate 603 to rotate through the transmission rod 601. At this time, the transmission plate 603 will drive the slide plate 604 to move through the transmission slot, so that the limit block 605 is away from the limit slot, and the connection with the protective shell 2 is released. Thereafter, the filter cartridge can be removed from the protective shell 2. The top plate 5 is removed, and the personnel clean the inside of the filter cartridge. When docking is required, the docking can be completed by operating the equipment in the direction. The rotation of the screw 606 drives the bottom end parts to operate, so that the limit rod 607 can be extended from the outer wall of the transmission rod 601, and then inserted into the inside of the slot 9. Because the screw 606 will not rotate with the rotation of the rotating rod, after the limit rod 607 is inserted into the inside of the slot 9, the transmission rod 601 can no longer rotate, thereby achieving the limiting effect, thereby ensuring the stability of the top plate 5 and the protective shell 2 after docking, and preventing loosening due to vibration.

[0027] Here’s how it works:

[0028] After the filter cartridge has been used for a period of time, it can be removed from the external equipment. At this time, the screw rod 606 can be rotated. When the screw rod 606 rotates, it will drive the lifting plate 609 to move downward. At this time, the limit plate will be restored by the tension spring 10, so that the limit plate is away from the slot 9, thereby releasing the limit. At this time, the rotating wheel 602 can be rotated, and the rotating wheel 602 will drive the transmission plate 603 to rotate through the transmission rod 601. At this time, the transmission plate 603 will drive the slide plate 604 to move through the transmission groove, so that the limit block 605 is away from the limit groove. At this time, the connection with the protective shell 2 is released, and thereafter the top plate 5 can be removed, and the personnel can clean the inside of the filter cartridge. When docking is required, the docking can be completed by operating the equipment in the direction.
