DETAILED DESCRIPTION
[0014] The specific implementation of the present invention will be further described in detail below with reference to the accompanying drawings.
[0015] Depend on Figures 1 to 4 A metal filter cartridge dust collector with a stable structure is provided, comprising a chassis 1, a cylinder wall 2 being fixed on the chassis 1, a cover plate 3 being installed above the cylinder wall 2, a circular ring 4 being fixed in the middle of the chassis 1, a filter cartridge 5 being placed in the cylinder wall 2, a first limiting ring 7 cooperating with the circular ring 4 being installed at the lower end of the filter cartridge 5, a second limiting ring 8 being installed at the upper end of the filter cartridge 5, a plurality of limiting blocks 9 being fixed on the outside of the first limiting ring 7, a limiting groove 10 cooperating with the limiting blocks 9 up and down is provided on the circular ring 4, a plurality of limiting holes 11 are provided in the radial direction of the circumference of the first limiting ring 7, the circular ring 4 is radially connected with a guide rod 12 cooperating with the limiting hole 11, a ball 13 is fixed at the other end of the guide rod 12, a spring 14 is sleeved on the guide rod 12, the spring 14 is located between the ball 13 and the circular ring 4, a turntable 15 is rotatably connected in the chassis 1, a protrusion 16 intermittently cooperating with the ball 13 is fixed on the inner side of the turntable 15
[0016] In order to skillfully control the rotation of the turntable 15 in the chassis 1 , a worm gear 17 is fixed to the outside of the turntable 15 , and a worm 18 is rotatably connected to the chassis 1 , and the worm 18 is engaged with the worm gear 17 .
[0017] The cover plate 3 is provided with an air inlet 19 .
[0018] The cylinder wall 2 is provided with a plurality of air outlets 20 around its circumference.
[0019] When the utility model is in use, when the metal filter cartridge 5 needs to be installed, the cover plate 3 is opened, the metal filter cartridge 5 is placed from top to bottom, the limit block 9 cooperates with the limit groove 10 up and down, the first limit ring 7 is clamped up and down inside the circular ring 4 to prevent the metal filter cartridge 5 from rotating, and the worm 18 is rotated. The worm 18 drives the worm gear 17 to rotate, and the worm gear 17 drives the turntable 15 to rotate, and the turntable 15 drives the protrusion 16 to rotate synchronously. With the rotation of the protrusion 16, the protrusion 16 begins to squeeze the ball 13. The ball structure is used to reduce friction, which helps the protrusion 16 to drive the ball 13 to move. The ball 13 drives the guide rod 12 to radially insert into the limit hole 11 in the circular ring 4. The spring 14 is in a continuously compressed state. When the guide rod 12 is fully inserted into the limit hole 11 , the worm 18 stops rotating, the lead angle of the worm is smaller than the equivalent friction angle between the meshing gear teeth, the worm gear has self-locking properties, and the turntable 15 can be fixed in a suitable position without other locking devices. Multiple guide rods 12 on the circumference of the ring 4 are synchronously inserted into the corresponding limiting holes 11, so that the first limiting ring 7 and the ring 4 are fixed together. The first limiting ring 7 is fixed in all directions up, down, left and right, with good fixing effect and stable structure. The second limiting ring 8 cooperates with the cylinder wall 2, and then the cover plate 3 is installed on the cylinder wall 2. The air inlet 19 is opened, and the gas to be filtered enters the metal filter cartridge 5, and the filtered gas is discharged from the air outlet 20. In addition, a rotating sealing ring is installed between the worm 18 and the chassis 1 to ensure the sealing of the chassis 1 and prevent air leakage from the chassis 1.
[0020] When the metal filter cartridge 5 needs to be replaced, the cover plate 3 is opened, the worm 18 is reversed, the worm 18 drives the worm wheel 17 to reverse, and the worm wheel 17 drives the turntable 15 to reverse and reset, the protrusion 16 moves away from the sphere 13, and under the reset action of the spring 14, the guide rod 12 is radially away from the limit hole 11 and reset, and the metal filter cartridge 5 can be taken out upward. The disassembly and assembly are convenient, the structure is stable, and the operation is simple.
[0021] This embodiment does not impose any formal restrictions on the shape, material, structure, etc. of the utility model. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the utility model are within the scope of protection of the technical solution of the utility model.
