[0024] Please see Figs. 1-3 This utility model provides a technical solution: a filter cartridge for a dry dust collector used in mining, including a steel mesh 1 and a filter element 2. The steel mesh 1 is fixed to the outside of the filter element 2, and a first side plate 3 and a second side plate 4 are fixed to both ends of the steel mesh 1 and the filter element 2, respectively. An air outlet 31 communicating with the inside of the filter element 2 is provided in the middle of the surface of the first side plate 3. A plurality of screw holes 32 are provided on the outer ring of the surface of the first side plate 3. The screw holes 32 penetrate the first side plate 3. In use, bolts can be used to cooperate with the screw holes 32 on the surface of the first side plate 3 to realize the installation and fixation of the first side plate 3 and the whole.

[0025] When in use, the air outlet 31 is connected to the air outlet pipe of the dust collector, and the steel mesh 1 is placed inside the dust collector housing. During operation, the dust-laden air is first initially filtered and dust-removed by the steel mesh 1, and then enters the interior to be filtered by the filter element 2. After that, it is discharged outward from the air outlet 31 through the air outlet pipe.

[0026] Two connecting rods 33 are vertically connected and fixed on both sides between the first side plate 3 and the second side plate 4. A cleaning ring 5 is slidably fitted on the outer ring of the steel mesh 1. A second through hole 52 is opened on both sides of the surface of the cleaning ring 5, so that the two connecting rods 33 can slide through the two second through holes 52 to pass through both sides of the cleaning ring 5. A cotton ring 51 is fixed on the inner ring of the cleaning ring 5 and is in contact with the outer surface of the steel mesh 1. When the cleaning ring 5 is guided to the reciprocating sliding position on the outer ring of the steel mesh 1 by the connecting rods 33, the cotton ring 51 reciprocates in contact with the outer surface of the steel mesh 1, which can remove and clean the dust on the surface of the steel mesh 1.

[0027] A pull plate 6 parallel to the side of the second side plate 4 is provided, and pull rods 61 are fixed to both sides of the pull plate 6. A first through hole 41 is opened on the surface of the second side plate 4 at the position aligned with the pull rod 61, so that the pull rod 61 can slide through the second side plate 4 through the first through hole 41. Then, the end of the pull rod 61 is fixed to the surface of the cleaning ring 5, and a pull ball 7 is fixed to the side of the middle position of the pull plate 6. When cleaning is required, the cover of the dust collector can be removed first, and then the pull plate 6 can be pulled by the pull ball 7. The pull rod 61 is used to pull the cleaning ring 5 back and forth multiple times to move it back and forth on the outer ring of the steel mesh 1 multiple times, so that the dust on its surface can be brushed off and cleaned by the cotton ring 51.

[0028] A screw hole 62 is provided in the middle of the surface of the pull plate 6, and a screw rod 71 is connected to the side of the pull ball 7. The pull ball 7 is installed on the side of the pull plate 6 by screwing the screw rod 71 into the screw hole 62, which can achieve the purpose of detachable installation of the pull ball 7. In order to save manpower, the pull ball 7 can be rotated to unscrew the screw rod 71 from the screw hole 62, and then an electric push rod can be installed inside the dust collector. The electric push rod is then connected to the pull plate 6 through the screw hole 62. Later, the pull plate 6 can be pulled by the pull rod 61 to achieve the purpose of cleaning.

[0029] In addition, magnets 53 are embedded and fixed on the surface of the cleaning ring 5. Multiple magnets 53 are evenly arranged. When in use, the cleaning ring 5 is pushed close to the first side plate 3, and the magnets 53 are used to attract and make the cleaning ring 5 and the first side plate 3 stick together, thus preventing the cleaning ring 5 from sliding during use.

[0030] In use, the first side plate 3 can be installed and fixed using bolts through the screw holes 32 on its surface, thus fixing the overall structure. The steel mesh 1 is placed horizontally within the dust collector's housing, while the outlet 31 connects to the dust collector's exhaust port. The pull plate 6 is pushed by the pull ball 7, causing the cleaning ring 5 to be pushed close to the first side plate 3 using the pull rod 61. The magnet 53 then attracts the cleaning ring 5 to the first side plate 3, bringing them into contact. Afterward, the dust collector's cover can be installed. Dust-laden air is initially filtered through the steel mesh 1 to remove large dust particles, then filtered again through the inner filter element 2, and finally discharged through the outlet 31. After a period of use... When a lot of dust accumulates on the surface of the steel mesh 1, the cover of the dust collector can be removed. Then, pull the pull plate 6 by pulling the ball 7, and use the pull rod 61 to pull the cleaning ring 5 back and forth multiple times on the outer ring of the steel mesh 1. This allows the cotton ring 51 to brush off the dust on its surface. Finally, push the cleaning ring 5 again to make it contact the first side plate 3 and adhere to it. After that, the cover of the dust collector can be installed and it can be used again. In order to achieve the purpose of dust removal without manual operation, an electric push rod can also be installed inside the dust collector. After rotating the ball 7, the screw 71 is unscrewed from the screw hole 62, and the electric push rod is connected to the pull plate 6 through the screw hole 62. Later, the purpose of cleaning can be achieved by pulling the pull plate 6 with the pull rod 61.
