The levers 34 are located on the left side of the corresponding snap rings 35. When the snap rings 35 move and contact with the levers 34, the levers 34 can drive the snap rings 35 to rotate. A guide rod 44 is fixedly connected to the left rear side of the bottom of the shell 1. The guide rod 44 slides through the rear side of the sliding plate 3 and is fixedly connected to the rear side of the partition 33 to guide the sliding plate 3. A card block 43 is slidably mounted on the guide rod 44. The inner side of the card block 43 is connected to the sliding plate 3. The rear side is in contact. When the block 43 moves, the block 43 can drive the sliding plate 3 to move. The upper part of the front side of the block 43 is fixedly connected to the rear ends of the three levers 34. The screw rod 42 is rotatably connected to the right rear side of the partition 33.

When the device is used, the exhaust gas passes through the dust gas The pipe 21 discharges the exhaust gas into the shell 1, and the exhaust gas first contacts with the cloth bag 31. The cloth bag 31 filters the dust in the exhaust gas, and the gas after dust filtration is discharged into the clean air pipe 22. The clean air pipe 22 discharges the gas after dust filtration. This is repeated, and the dust in the exhaust gas can be continuously filtered and discharged. When the cloth bag 31 passes dust for a long time, the electromagnetic pulse valve 2 is started. The electromagnetic pulse valve 2 vibrates the cloth bag 31 through the action of the clean air pipe 22 and the cage frame 32, so that the dust filtered out of the cloth bag 31 falls to the bottom of the shell 1, and then the electromagnetic pulse valve 2 is closed, and the cloth bag 31 stops being vibrated. When all the exhaust gas is processed, the servo motor 41 is started to drive the screw rod 42 to reverse, and the screw rod 42 reverses to drive the block 43 to move downward and reset, so that the cloth bag 31 moves downward and resets and disengages from the cage frame 32 and the partition plate 33. Then the door of the shell 1 is pulled to open, and the sliding plate 3 is pulled forward to move. The sliding plate 3 moves forward to drive the snap ring 35 to move forward, and the snap ring 35 moves forward to drive the cloth bag 31 to move forward. When the snap ring 35 moves forward and engages with the lever 34, the lever 34 drives the snap ring 35 to rotate forward, and the snap ring 35 rotates forward to drive the ball 36 to rotate forward.

The snap ring 35 moves upward to drive the cloth bag 31 to move upward. The snap ring 35 moves upward and disengages from the spiral groove on the hole of the sliding plate 3 to stop locking the snap ring 35. The bag 31 is then replaced by the new bag 31 through the sliding plate 3, and the snap ring 35 drives the ball bearing 36 to contact the spiral groove on the hole of the sliding plate 3, and the sliding plate 3 is pushed to move backward and reset, so that the snap ring 35 is engaged with the lever 34 again, and the lever 34 drives the snap ring 35 to reverse, and the snap ring 35 reverses and drives the ball bearing 36 to reverse, and the ball bearing 36 moves downward and resets through the spiral groove on the hole of the sliding plate 3, and the ball bearing 36 moves downward and resets to cooperate with the spiral groove on the sliding plate 3 to lock the snap ring 35, and the locking of the bag 31 is completed. At this time, the bag 31 is corresponding to the cage frame 32, and the door of the shell 1 is closed. Example 2

[0034] On the basis of embodiment 1, it also includes a fixed rack 5, a fixed frame 51, a bevel gear ring 52, a spiral plate 53, a gear shaft 54 ​​and a bevel gear 55, see Figure 6 and Figure 7 As shown, three fixed frames 51 are evenly spaced and fixedly connected to the bottom of the sliding plate 3, and the fixed frames 51 are sleeved on the cloth bag 31. The top of the fixed frame 51 is connected to a bevel gear ring 52 for symmetrical rotation front and back. The bottom of the bevel gear rings 52 on both sides of the front and rear are fixedly connected to spiral plates 53, and the spiral plates 53 are in contact with the outer side of the cloth bag 31. When the spiral plates 53 rotate, the spiral plates 53 can level the cloth bag 31. The right side of the top of the three fixed frames 51 is connected to a gear shaft 54 ​​for symmetrical rotation front and back. The left ends of the gear shafts 54 on both sides of the front and rear are fixedly sleeved with bevel gears 55, and the bevel gears 55 are meshed with the bevel gear ring 52. Three fixed racks 5 are evenly spaced and fixedly connected to the bottom of the shell 1. The fixed racks 5 are meshed with the gear shaft 54 ​​to drive the gear shaft 54 ​​to rotate, and the teeth of the fixed racks 5 are arranged on the front side of the top.

[0035] It also includes an L-shaped frame 6, a top rod 61, an inclined frame 62, a return spring 63 and a contact plate 64, see Figure 8 As shown, three L-shaped frames 6 are fixedly connected at even intervals on the front side of the bottom of the sliding plate 3, and the lower part of the L-shaped frame 6 is located below the cloth bag 31. The bottom of the three L-shaped frames 6 is symmetrically slidably connected with a push rod 61, and the front and rear push rods 61 are respectively in contact with the bottom of the front and rear cloth bags 31. When the push rod 61 moves upward, the push rod 61 can drive the cloth bag 31 to move upward. A contact plate 64 is fixedly connected between the bottom ends of the two push rods 61 on each side, and reset springs 63 are symmetrically connected between the tops of the three contact plates 64 and the outer bottoms of the three L-shaped frames 6. The reset spring 63 is sleeved on the push rod 61, and three inclined frames 62 are fixedly connected at even intervals on the lower part of the inner rear side surface of the shell 1. The inclined surface of the inclined frame 62 is an inclined structure with a low rear and a high front. The inclined frame 62 contacts with the contact plate 64 to limit the contact plate 64.

[0036] When the operator pulls the sliding plate 3 forward, the sliding plate 3 also drives the fixed frame 51 forward, and the fixed frame 51 moves forward, drives the bevel gear ring 52 and the gear shaft 54 ​​forward, and the bevel gear ring 52 moves forward, drives the spiral plate 53 forward, and the spiral plate 53 moves forward synchronously with the cloth bag 31. When the gear shaft 54 ​​moves forward and meshes with the fixed rack 5, the fixed rack 5 drives the gear shaft 54 ​​to reverse, and the reverse rotation of the gear shaft 54 ​​drives the bevel gear 55 to reverse, and the reverse rotation of the bevel gear 55 drives the bevel gear ring 52 Reverse, the bevel gear ring 52 reverses and drives the spiral plate 53 to reverse, and the spiral plate 53 reverses and drives the cloth bag 31 to move upward. At the same time, the spiral groove on the hole of the sliding plate 3 also drives the ball 36 to move upward, which makes the snap ring 35 drive the cloth bag 31 to move upward. When the gear shaft 54 ​​continues to move forward and disengages from the fixed rack 5, the gear shaft 54 ​​stops reversing, and the gear shaft 54 ​​stops driving the bevel gear 55 to reverse. The bevel gear ring 52 also stops driving the spiral plate 53 to reverse, and the snap ring 35 can be removed to replace the cloth bag 31. When the cloth bag 31 is replaced, the new cloth bag 31 contacts the spiral plate 53, pushing the sliding plate 3 to move backward and drive the cloth bag 31 to move backward and reset through the snap ring 35. The sliding plate 3 also drives the gear shaft 54 ​​to move backward through the fixed frame 51. The gear shaft 54 ​​moves backward and meshes with the fixed rack 5. The fixed rack 5 drives the gear shaft 54 ​​to rotate forward. The forward rotation of the gear shaft 54 ​​drives the bevel gear 55 to rotate forward. The forward rotation of the bevel gear 55 drives the bevel gear ring 52 to rotate forward. The forward rotation of the bevel gear ring 52 drives the spiral plate 53 to rotate forward. The forward rotation of the spiral plate 53 smoothes the cloth bag 31. When the sliding plate 3 moves backward and drives the cloth bag 31 to move backward and reset through the snap ring 35, the sliding plate 3 stops moving backward. At this time, the gear shaft 54 ​​is disengaged from the fixed rack 5, the gear shaft 54 ​​stops rotating forward, and the spiral plate 53 also stops rotating forward to smooth the cloth bag 31. In this way, wrinkles on the cloth bag 31 can be prevented from affecting the filtering of dust in the exhaust gas, thereby ensuring the filtering effect of the cloth bag 31 on dust.

[0037] When the sliding plate 3 is moved forward and the cloth bag 31 is moved forward through the retaining ring 35, the sliding plate 3 also drives the L-shaped frame 6 to move forward, and the L-shaped frame 6 moves forward to drive the push rod 61 to move forward, and the push rod 61 moves forward to drive the contact plate 64 to move forward. When the contact plate 64 moves forward and disengages from the inclined frame 62, the contact plate 64 stops being limited. Due to the action of the reset spring 63, the contact plate 64 moves upward and resets to drive the push rod 61 to move upward, and the push rod 61 moves upward to compress the cloth bag 31. When the ball 36 moves upward and disengages from the spiral groove on the hole of the sliding plate 3, the cloth bag 31 stops being limited, and the cloth bag 31 can also move upward to a suitable position. When all the cloth bags 31 move upward to a suitable position, the sliding plate 3 stops being pulled forward, the sliding plate 3 stops driving the L-shaped frame 6 to move forward, and the L-shaped frame 6 stops driving the contact plate 64 to move forward through the push rod 61, and the cloth bag 31 moving upward can be removed for replacement. When the new cloth bag 31 is replaced, the cloth bag 31 contacts the push rod 61, pushing the sliding plate 3 to move backward, so that the contact plate 64 moves backward and contacts the inclined frame 62, and the inclined frame 62 drives the contact plate 64 to move downward, and the reset spring 63 is stretched, and the contact plate 64 moves downward to drive the push rod 61 to move downward, and the push rod 61 moves downward without limiting the cloth bag 31. Due to the effect of gravity, the cloth bag 31 moves downward and resets, and drives the ball 36 to move downward and contact the spiral groove on the hole of the sliding plate 3 through the snap ring 35, and then the snap ring 35 is engaged with the lever 34 and pushed to reverse, so that the ball 36 is reset and cooperates with the spiral groove on the hole of the sliding plate 3 to lock the snap ring 35, and also locks the cloth bag 31. In this way, a part of the cloth bag 31 can be placed above the sliding plate 3, so that it is convenient for operators to take it out and improve the efficiency of taking materials. Example 3

[0038] On the basis of the embodiment 1 and the embodiment 2, a rubber pad 7 is also included. Fig. 9 As shown, the top ends of the six push rods 61 are fixed with rubber pads 7 , and the rubber pads 7 are in contact with the cloth bag 31 to protect the cloth bag 31 .

[0039] It also includes a fixing plate 8 and an air guide plate 81, see Fig.10 As shown, a fixing plate 8 is fixedly connected to the lower left side of the shell 1 , and an air guide plate 81 is fixedly connected to the fixing plate 8 . The air guide plate 81 is inclined and inclined toward the cloth bag 31 .

[0040] When the push rod 61 moves upward, the push rod 61 also drives the rubber pad 7 to move upward. The push rod 61 drives the cloth bag 31 to move upward for compression through the rubber pad 7. Due to the action of the rubber pad 7, the cloth bag 31 can be protected. In this way, the push rod 61 can be prevented from directly contacting the cloth bag 31 and causing wear, thereby ensuring the integrity of the cloth bag 31.

[0041] When the exhaust gas is discharged into the housing 1 through the dust pipe 21, the exhaust gas first contacts the air guide plate 81, and the air guide plate 81 guides the exhaust gas, and the exhaust gas after being guided contacts the bag 31 accurately to filter the dust. In this way, the exhaust gas can be prevented from floating to other places in the housing 1, making it difficult to contact the bag 31 to filter the dust in the first time, thereby improving the efficiency of dust filtering.

[0042] Finally, it is necessary to point out that the above content is only used to help understand the technical solution of the present invention and cannot be understood as limiting the scope of protection of the present invention; non-essential improvements and adjustments made by technical personnel in the field of technology based on the above content of the present invention are all within the scope of protection required by the present invention.
