[0030] Eight fixing blocks 15 are movably provided on the fixing ring 2 , and a fixing groove 16 is provided on one side of each fixing block 15 . Four fixing chambers 17 are provided in the fixing ring 2 .

[0031] In this embodiment, during the use of the filter bag main body 1, the motor 7 is started, and the motor 7 drives the half gear 6 to rotate. When the half gear 6 is meshed with the rack 5, as the half gear 6 rotates, the rack 5 moves along the sliding connection with the drive chamber 4, and the rack 5 drives the limit plate 9 to move, and the first spring 10 is compressed. At the same time, the rack 5 drives the two moving seats 11 to move, and the moving seat 11 drives the knocking frame 12 to move, and the knocking frame 12 drives the knocking block 14 to move, so that the knocking block 14 on one knocking frame 12 contacts the filter bag main body 1 and knocks it, and the other knocking frame 12 drives the knocking block 14 to separate from the filter bag. When the half gear 6 rotates to separate from the rack 5, under the action of the first spring 10, the rack 5 moves back to its original position, so that the knocking block 14 on the other knocking frame 12 knocks the filter bag, and the operation is repeated. The knocking blocks 14 on the two knocking frames 12 will alternately knock the filter bag to knock off the dust adhered to the filter bag main body 1.

[0032] More specifically, during the use of the filter bag body 1, the two knocking blocks 14 on the knocking frames 12 will alternately knock the filter bag to vibrate and clean the filter bag body 1. When the entire filter bag body 1 needs to be installed, the entire filter bag is placed on the flower plate from top to bottom, so that the fixing groove 16 on the fixing block 15 is aligned with the flower plate, and the fixing block 15 moves outward so that the flower plate is inserted into the fixing groove 16, thereby installing the entire filter bag, and then the conventional installation method of the frame in the prior art is used to put the upper end of the frame on the fixing ring 2, and the lower end of the frame is extended into the filter bag body 1.

[0033] See also Figure 1-5 , as an implementation method for moving the fixed block 15: a screw 18 is rotatably provided in each of the fixed chambers 17, a movable plate 19 is threadedly connected to the screw 18, the movable plate 19 is fixedly connected to the two fixed blocks 15, one end of the screw 18 passes through the fixed chamber 17 and is fixedly connected to a bevel gear 20, the bevel gear 20 is meshedly connected to a bevel gear ring 21, the bevel gear 20 is fixedly connected to a rotating ring 22, and the rotating ring 22 is rotatably connected to the fixed ring 2.

[0034] Specifically, the rotating ring 22 is rotated, and the rotating ring 22 drives the conical gear ring 21 to rotate, so that the four conical gears 20 rotate, and the conical gears 20 drive the screw 18 to rotate. Since the screw 18 is threadedly connected to the moving plate 19, the moving plate 19 drives the fixed block 15 to move, and the fixed block 15 moves out of the fixed ring 2.

[0035] See also Figure 1-5 As an implementation method for replacing the knocking frame 12: one side of the movable seat 11 is recessed inward to form an installation chamber 23, and a push plate 24 is movably provided in the installation chamber 23, and one side of the push plate 24 extends to the outside of the installation chamber 23, and a second spring 25 is fixedly connected between one side of the push plate 24 and the installation chamber 23, and an insertion rod 26 is fixedly provided on the other side of the push plate 24, one end of the insertion rod 26 passes through the installation chamber 23 and is inserted into the knocking frame 12, and two installation grooves 27 matching the knocking frame 12 are provided on the movable seat 11.

[0036] Specifically, when the striking frame 12 or the striking block 14 is damaged and needs to be replaced, the push plate 24 is pushed, and the push plate 24 drives the insertion rod 26 to move, so that the insertion rod 26 moves out of the striking frame 12, and the second spring 25 is compressed, pulling the striking frame 12 to move it from the mounting groove 27, so that the striking frame 12 and the striking block 14 can be disassembled, and the replaced striking frame 12 is inserted into the mounting groove 27, and the push plate 24 is released. Under the push of the second spring 25, the push plate 24 drives the insertion rod 26 to be inserted into the striking frame 12, thereby installing the striking frame 12 and the striking block 14.

[0037] In summary, when the overall equipment is in use:

[0038] When the entire filter bag needs to be installed on the flower plate, when the entire filter bag body 1 needs to be installed, the entire filter bag is placed on the flower plate from top to bottom, so that the fixing groove 16 on the fixing block 15 is aligned with the flower plate, and the rotating ring 22 is rotated. The rotating ring 22 drives the conical gear ring 21 to rotate, so that the four conical gears 20 rotate, and the conical gear 20 drives the screw 18 to rotate. Since the screw 18 is threadedly connected to the moving plate 19, the moving plate 19 drives the fixing block 15 to move, and the fixing block 15 is moved out of the fixing ring 2, so that the flower plate is stuck in the fixing groove 16, thereby installing the entire filter bag, and then the conventional installation method of the skeleton in the prior art is used to put the upper end of the skeleton on the fixing ring 2, and extend the lower end of the skeleton into the filter bag body 1.

[0039] When the entire filter bag is in use, the motor 7 is started, and the motor 7 drives the half gear 6 to rotate. When the half gear 6 is meshed with the rack 5, as the half gear 6 rotates, the rack 5 moves along the sliding connection with the drive chamber 4, and the rack 5 drives the limit plate 9 to move, and the first spring 10 is compressed. At the same time, the rack 5 drives the two moving seats 11 to move, and the moving seat 11 drives the knocking frame 12 to move, and the knocking frame 12 drives the knocking block 14 to move, so that the knocking block 14 on one knocking frame 12 contacts the filter bag body 1 and knocks it, and the other knocking frame 12 drives the knocking block 14 to separate from the filter bag. When the half gear 6 rotates to separate from the rack 5, under the action of the first spring 10, the rack 5 moves back to its original position, so that the knocking block 14 on the other knocking frame 12 knocks the filter bag, and the operation is repeated. The knocking blocks 14 on the two knocking frames 12 will alternately knock the filter bag to knock off the dust adhered to the filter bag body 1.

[0040] When the damaged striking frame 12 and striking block 14 need to be replaced, the push plate 24 is pushed, and the push plate 24 drives the insertion rod 26 to move, so that the insertion rod 26 moves out of the striking frame 12, and the second spring 25 is compressed, pulling the striking frame 12 to move it out of the mounting groove 27, so that the striking frame 12 and the striking block 14 can be disassembled, and the replaced striking frame 12 is inserted into the mounting groove 27, and the push plate 24 is released. Under the push of the second spring 25, the push plate 24 drives the insertion rod 26 to be inserted into the striking frame 12, thereby installing the striking frame 12 and the striking block 14.

[0041] In all the schemes mentioned above, the connection between two parts can be selected according to actual conditions by welding, bolt and nut matching connection, bolt or screw connection or other well-known connection methods, which are not described here one by one. In the above, all fixed connections are preferably welded.
