Description

Technical Field

[0001] This utility model relates to the field of dust collector bag disassembly technology, specifically an industrial low-labor-intensity dust collector bag remover. Background Technology

[0002] In industrial production, such as thermal power, cement, steel, and chemical industries, baghouse dust collectors are common dust collection devices. The filter bag is the core filtration element of the baghouse dust collector. The filter bag fabric is typically made of polyester fiber, glass fiber, or PPS, tightly packed to intercept dust. Normal temperature bags use polyester / polypropylene, while medium- and high-temperature bags use heat-resistant materials such as aramid, P84, or glass fiber. The bag opening usually uses an elastic ring, also called an expansion ring, to secure the filter bag to the slot in the dust collector's tube sheet.

[0003] However, traditional bag replacement mainly relies on manual operation, which involves changing the expanded ring shape into a concave shape and then manually lifting the dust bag. During manual operation, since there are multiple dust bags on the bag filter, personnel need to repeatedly bend over or squat to operate, which puts a great burden on the physical burden of personnel. To address this, we propose an industrial low-labor-intensity dust bag remover. Utility Model Content

A plug-in block is fixedly connected to one end of the rotatable handle extending out of the support member. A plug-in rod is inserted into the plug-in groove on the side of the plug-in block away from the support member. The other ends of the two plug-in rods are fixedly connected to a fixing plate.

[0009] Preferably, the two connecting rods are used for the dust bag to pass through, and the dust bag is rolled up by rotating the connecting rods with a throttle.

[0010] Preferably, the baffle is used to provide support for the slide rail, and the baffle is also used to block dust during the dust bag winding process.

[0011] Preferably, a support frame is fixedly connected to the top of the baffle, and a pulley for guiding the traction rope is rotatably connected to one side of the two support frames via bearings. A connecting plate is fixedly connected to the bottom of one side of the baffle, and a winding reel is rotatably connected to one side of the two connecting plates via bearings. One end of the central shaft of the winding reel passes through one of the connecting plates and is fixedly connected to a first gear. The first gear is connected to a second gear through meshing transmission. A movable shaft is fixedly sleeved inside the second gear.

After the two clamping arms come together, the clamping strip and the first clamping claw are concave inward under the force, which can simulate the process of a human hand turning the expansion ring into a concave shape. This allows the operator to simulate the hand operation process without squatting or bending over. The concave expansion ring can easily remove the dust bag, thereby avoiding operation jamming, reducing the operator's workload, and improving work efficiency.

[0015] By pressing down on the pedal with the user's feet, the speed ratio is changed through the sector gear, the third gear, the second gear, and the first gear. This causes the winding wheel to wind up the traction rope and pull the clamp arm through the slider, thereby reducing the burden on the hands when pulling upwards. This makes it easier to pull out the dust bag by utilizing the body weight, and reduces the burden on the arms. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides a technical solution: such as Figures 1-7The illustrated industrial low-labor-intensity dust collector bag extractor includes a baffle 1. A slide rail 2 is fixedly connected to one side of the baffle 1. A slider 4 is slidably connected inside the slide rail 2. A fixed shaft 5 is fixedly connected to one side of the slider 4. Two cross-shaped clamping arms 6 are hinged to the side surface of the fixed shaft 5. A clamping assembly for gripping the top edge of the dust bag is provided at the end of the clamping arm 6 away from the hand-held part. The clamping assembly includes a first connecting member 7. One side of the first connecting member 7 is fixedly connected to the bottom of the clamping arm 6. A first claw 9 that engages with the groove on the outer wall of the dust bag expansion ring is fixedly connected to the bottom of the first connecting member 7. A clamping strip 8 that abuts against the inner wall of the dust bag expansion ring is fixedly connected to the top of the first connecting member 7. A second claw 12 is fixedly connected to the bottom of the first connecting member 7 of the other clamping assembly. An arc plate 10 is fixedly connected to the opposite side of the first connecting piece 7 with the second claw 12. In use, first, the covers inside the dust bag are removed one by one. Then, the device is moved above the corresponding dust bag via the roller 15. The operator is positioned on the side of the baffle 1 away from the clamping arms 6 and facing the baffle 1. Both hands are gripped on the tops of the two clamping arms 6, and the head is peering over the baffle 1 for observation. The hands move downwards, causing the clamping arms 6 to move down along the slide rail 2 via the slider 4. When the clamping strip 8 enters the dust bag, the hands move backwards against the force of the tension spring 13, causing the bottoms of the two clamping arms 6 to separate. The two clamping strips 8 move closer to the inner wall of the dust bag's expansion ring until they abut, and under the reaction force, the clamping strips 8 bend and deform. As the clamping strips 8 bend, they contact the first claw. The distance between the first and second jaws 9 is increased, and the arc plate 10 and the second jaw 12 on the other clamp arm 6 are also increased. At this time, the clamp arm 6 is lowered again, so that the bottom of the first jaw 9 and the second jaw 12 abut against the dust collector tube sheet. Then, the hands are brought together, and the first jaw 9 and the second jaw 12 move towards the middle, so that their tips engage with the groove on the outer wall of the dust bag expansion ring. At the same time as the first jaw 9 and the second jaw 12 move towards the middle, the clamping strip 8 returns to its original position through elastic deformation force, until the expansion ring is clamped by the two clamping strips 8 respectively with the first jaw 9 and the second jaw 12. As the hands gradually move closer, the first jaw 9 and the second jaw 12 apply an inward force to the expansion ring. Since the contact area between the second jaw 12 and the arc plate 10 and the expansion ring is much larger than that of the first jaw 9, the clamping strip 12 is used to clamp the expansion ring. The contact surfaces of the first claw 9 and clamping bar 8 with the expansion ring make the force exerted by the first claw 9 and clamping bar 8 on the expansion ring more concentrated, causing the edge of the expansion ring held by the first claw 9 and clamping bar 8 to be concave inward. When the gripping arm 6 is closed to its limit, the expansion ring forms a concave shape. Then, the operator steps on the pedal 32, causing the connecting shaft 31 and sector gear 29 to rotate, and simultaneously driving the third gear 28, the second gear 27 and the first gear 25 to rotate, thereby causing the winding wheel 24 to wind up the traction rope, so that the traction rope pulls the slider 4 upward through the pulley 22, thereby raising the gripping arm 6. As the gripping arm 6 is pulled upward, the expansion ring can be easily removed from the groove of the dust collector tube sheet. After being pulled to a certain height, the insertion rod 19 is inserted into the insertion hole of the insertion block 17.At this point, the dust bag is positioned between the two connecting rods 19. Then, the clamping arms 6 are separated again, causing the clamping strips 8 to move to both sides. During this process, the expansion ring resets and gradually deforms into an ellipse under the force applied to both sides by the clamping strips 8. The first claw 9 and the second claw 12 disengage from the groove on the outer wall of the expansion ring. The operator pulls the bag downwards, causing the dust bag to detach from the clamping strips 8. The expansion ring, under elastic deformation, returns to a circular shape and locks onto the two connecting rods 19. Then, the handle 18 is turned to retract the dust bag. Finally, the retracted dust bag and connecting rods 19 are removed, and the connecting rods 19 are pulled out of the retracted dust bag. At this point, the dust bag removal and retraction operations are complete.

[0027] like Figure 1 , Figure 2 and Figure 5 As shown, a second connecting member 11 in an arc shape is fixedly connected to the opposite side of the first connecting member 7 with the second claw 12. The clamping bar 8 is made of elastically deformable metal. A tension spring 13 for providing force is fixedly connected to the opposite side of the two clamping arms 6.

[0028] like Figure 1 , Figure 2 and Figure 4 As shown, a groove 3 is provided on one side of the slide rail 2, and the slider 4 slides in the groove 3. A U-shaped bracket 14 is fixedly connected to the bottom of the baffle 1. A roller 15 is rotatably connected to the opposite side of the bracket 14 via a rotating shaft. A support leg 33 is fixedly connected to the opposite side of the bracket 14.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, a support member 16 for providing support is fixedly connected to the top side of the bracket 14. A throttle handle 18 is rotatably connected inside the support member 16 via a bearing. A plug-in block 17 is fixedly connected to one end of the throttle handle 18 extending out of the support member 16. A plug-in rod 19 is inserted into the plug-in groove on the side of the plug-in block 17 away from the support member 16. The other ends of the two plug-in rods 19 are fixedly connected to a fixing plate 20.

[0030] like Figure 1 , Figure 2 and Figure 3 As shown, the dust bag passes through between the two plug rods 19, and the dust bag is rolled up by rotating the plug rods 19 with the throttle 18.

[0031] like Figure 1 , Figure 2 and Figure 3As shown, the baffle 1 provides support for the slide rail 2 and also blocks dust during the dust bag winding process. Through the cooperation of the clamping strip 8, the first claw 9, the arc plate 10, and the second claw 12, the first claw 9 and the second claw 12 clamp and fix the expansion ring of the dust bag through the clamping strip 8. After the two clamping arms 6 come together, the clamping strip 8 and the first claw 9 are concave into the expansion ring under the force, which can simulate the process of a person's hand turning the expansion ring into a concave shape. This allows the operator to simulate the hand operation process without squatting or bending over. The concave expansion ring can easily remove the dust bag, thereby avoiding operation jamming, reducing the operator's workload, and improving work efficiency.

[0032] like Figure 4 , Figure 6 and Figure 7 As shown, a support frame 21 is fixedly connected to the top of the baffle 1. A pulley 22 for guiding the traction rope is rotatably connected to one side of the two support frames 21 via bearings. A connecting plate 23 is fixedly connected to the bottom of one side of the baffle 1. A winding reel 24 is rotatably connected to one side of the two connecting plates 23 via bearings. One end of the central shaft of the winding reel 24 passes through one of the connecting plates 23 and is fixedly connected to a first gear 25. The first gear 25 is meshed with a second gear 27. A movable shaft 26 is fixedly sleeved inside the second gear 27. One end of the movable shaft 26 is rotatably connected to one side of one of the connecting plates 23 via bearings. The other end of the movable shaft 26 is fixedly connected to a third gear 28. 8 is connected by a sector gear 29 through meshing transmission. An extension rod 30 is fixedly connected to the bottom of one side of the baffle 1. A connecting shaft 31 is rotatably connected to one side of the extension rod 30 through a bearing. The center of the sector gear 29 is fixedly sleeved on the side surface of the connecting shaft 31. A pedal 32 is fixedly sleeved on the side surface of the connecting shaft 31. When the person presses down on the pedal 32 with their feet, the speed ratio is changed through the sector gear 29, the third gear 28, the second gear 27 and the first gear 25. This causes the winding wheel 24 to wind up the traction rope and lift the clamp arm 6 through the slider 4, thereby reducing the burden of lifting the hand upward. This makes it easier to pull out the dust bag by using the weight of the human body and reduces the burden on the arm.

[0033] like Figure 4 , Figure 6 and Figure 7 As shown, one end of the traction rope is fixedly connected to the top of the slider 4, and the other end of the traction rope is fixedly connected to the side surface of the reel 24.

[0034] Working principle: In use, first remove the covers from the dust bags one by one. Then, move the device above the corresponding dust bag via roller 15. The operator stands on the side of baffle 1 away from the clamp arms 6 and faces the baffle 1. The operator holds the tops of the two clamp arms 6 with both hands, and looks over the baffle 1 to observe. The operator moves their hands down, causing the clamp arms 6 to move down along the slide rail 2 via the slider 4. When the clamping strips 8 enter the dust bag, the operators move their hands against the force of the tension spring 13, causing the bottoms of the two clamp arms 6 to separate. The two clamping strips 8 move closer to the inner wall of the dust bag expansion ring until they come into contact. Under the reaction force, the clamping strips 8 bend and deform. As the clamping strips 8 bend, the distance between the clamping strips 8 and the first claw 9 increases. The arc plate 10 and the second jaw 12 on the other clamp arm 6 are also pulled apart. At this time, the clamp arm 6 is lowered again so that the bottom of the first jaw 9 and the second jaw 12 abut against the dust collector tube sheet. Then, the hands are brought together, and the first jaw 9 and the second jaw 12 move towards the middle, so that their tips engage with the groove on the outer wall of the dust bag expansion ring. As the first jaw 9 and the second jaw 12 move towards the middle, the clamping strip 8 returns to its original position through elastic deformation until the expansion ring is clamped by the two clamping strips 8 with the first jaw 9 and the second jaw 12 respectively. As the hands gradually move closer, the first jaw 9 and the second jaw 12 apply an inward force to the expansion ring. Because the second jaw 12 and the arc plate 10 are in contact with the expansion ring, the expansion ring is clamped. The contact surface of the expansion ring is much larger than the contact surface between the first claw 9 and the clamping bar 8 and the expansion ring, making the force exerted by the first claw 9 and the clamping bar 8 on the expansion ring more concentrated. This causes the edge of the expansion ring held by the first claw 9 and the clamping bar 8 to be concave inward. When the gripping arm 6 is closed to its limit, the expansion ring forms a concave shape. Then, the operator steps on the pedal 32, causing the connecting shaft 31 and the sector gear 29 to rotate, which in turn drives the third gear 28, the second gear 27, and the first gear 25 to rotate. This causes the winding wheel 24 to wind up the traction rope, which pulls the slider 4 upward through the pulley 22, thereby raising the gripping arm 6. As the gripping arm 6 is pulled upward, the expansion ring can be easily removed from the groove in the dust collector tube sheet. Once a certain height is reached, insert the plug rod 19 into the plug hole of the plug block 17. At this time, the dust bag is located between the two plug rods 19. Then, separate the clamp arms 6 again, so that the clamping strip 8 moves to both sides again. During the process, the expansion ring resets and gradually deforms into an ellipse under the force applied to both sides by the clamping strip 8. The first claw 9 and the second claw 12 disengage from the groove on the outer wall of the expansion ring. The person pulls the cloth bag down, so that the dust bag disengages from the clamping strip 8. The expansion ring returns to a circle under the action of elastic deformation and is locked on the two plug rods 19. Then, turn the handle 18 to make the dust bag roll up. Finally, remove the rolled-up dust bag and plug rod 19, and pull out the rolled-up dust bag with the plug rod 19. At this time, the dust bag removal and rolling-up operation is completed.
