[0001] The invention belongs to the technical field of filter bag replacement for dust removal equipment, and in particular relates to a dust collector filter bag removal device. Background Art

[0002] During the replacement of filter bags in purification and desulfurization systems in large quantities, the traditional operation method is to use manpower to take out the filter bags and fold them for easy storage. Since each filter bag is several meters long, generally 6m-10m, it takes a long time to take out and fold them, occupies a large space, and is completed by manpower. This operation method not only increases the labor intensity of employees, but also prolongs the operation time, lows work efficiency, and increases labor costs.

[0003] In the prior art, there is no relevant equipment for replacing and removing filter bags. If a general traditional winding device is used, although the filter bag can be wound and taken out, when used as a whole, because the filter bag is wound on the winding device, it needs to be removed from the winding shaft with great effort. The operation is still cumbersome, time-consuming and laborious. Summary of the invention

The springs are respectively connected to the adjusting blocks. A semi-circular hole, a tapered hole and an arc-shaped hole are sequentially arranged on one side of the adjusting block along the axial inner side. When the tapered head is arranged in the tapered hole in a matching manner, the springs make the two adjusting blocks approach each other and be received in the chute. When the mating part is arranged in the arc-shaped hole in a matching manner, the mating part squeezes the two adjusting blocks to move away from each other and extend out of the chute.

[0008] Optionally, a step groove is provided at one end of the adjusting block, and the step groove is arranged in cooperation with the fixing block. When the step groove abuts against the fixing block, the two adjusting blocks abut against each other.

[0009] Optionally, an installation groove is provided in the adjusting block, and the spring is arranged in the installation groove.

[0010] Optionally, the driving device includes a rotating shaft and a lead screw. One end of the rotating shaft is connected with a lead screw, and the lead screw is connected with a turntable.

Detailed implementation manners

[0034] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention.

[0035] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] As Figures 1 to 14As shown in the figure, a dust collector filter bag removal device includes a turntable 3 connected to a driving device. On one side of the turntable 3, two clamping arms 4 are arranged at a fixed distance apart. A chute 41 is provided through the clamping arms 4. In each chute 41, two adjusting blocks 7 are symmetrically arranged. A total of four adjusting blocks 7 are arranged on the two clamping arms 4, and the two adjusting blocks 7 can slide in the chute 41 respectively. On the turntable 3, two cross bars 32 are fixedly arranged at a fixed distance apart. A number of guide rods 33 are connected between the two cross bars 32. In the present invention, the guide rods 33 are arranged in two. The guide rods 33 are passed through the chute 41, that is, the two guide rods 33 pass through the chute 41 of the two clamping arms 4. A sliding hole 72 is provided on the adjusting block 7. The number of the sliding holes 72 is the same as the number of the guide rods 33, and the sliding holes 72 are slidably connected with the guide rods 33. The device further includes an adjusting mechanism for driving the two adjusting blocks 7 in any chute 41 to approach or move away from each other.

[0038] When clamping the filter bag, the two adjusting blocks 7 in the same chute 41 move away from each other, and the filter bag is inserted into the gap between the two clamping arms 4. Then, the adjusting mechanism is used to drive the two adjusting blocks 7 in the same chute 41 to move away from each other, so that the two adjusting blocks 7 on the inner sides of the two clamping arms 4 approach each other to clamp the filter bag, and the two adjusting blocks 7 on the outer sides of the two clamping arms 4 move away from each other to adjust the width of the clamping arms 4. Then, the turntable 3 can be driven to rotate, and the filter bag is wound around the rotating assembly jointly composed of the clamping arms 4 and the adjusting blocks 7. On the contrary, when the wound filter bag needs to be unloaded, the two adjusting blocks 7 on the inner sides of the two clamping arms 4 move away from each other to loosen the clamping of the filter bag, and the two adjusting blocks 7 on the outer sides of the two clamping arms 4 approach each other, that is, the width of the clamping arms 4 is reduced. In this case, the wound filter bag as a whole will not be in a tense state, and it can be easily removed.

[0039] In summary, the device of the present invention can quickly wind the filter bag and can easily unload the wound filter bag, and the overall operation is simple and fast.

[0040] Embodiment 2

[0041] Furthermore, this embodiment further designs an adjusting mechanism for driving the two adjusting blocks 7 in any chute 41 to approach or move away from each other.

[0042] The adjusting mechanism includes a U-shaped bolt 6. One end of the bolt 6 extends with two cylindrical mating parts 61, and the end of the mating part 61 is provided with a tapered head 62. The end of the clamping arm 4 is provided with a positioning hole 42 communicating with the chute 41. The shape and size of the positioning hole 42 are the same as those of the mating part 61, and the mating part 61 is slidably arranged in the positioning hole 42. Two fixing blocks 34 are arranged at a fixed distance apart on the two guide rods 33. One spring 35 is arranged on each side of each fixing block 34. The fixing block 34 is arranged in the middle of the chute 41. The two adjusting blocks 7 in each chute 41 are respectively located on both sides of the fixing block 34, and the springs 35 are respectively connected to the adjusting blocks 7, that is, the two adjusting blocks 7 on both sides of the fixing block 34 are connected by the springs 35. On one side of the adjusting block 7, a semi-circular hole 74, a tapered hole 75 and an arc-shaped hole 76 are sequentially arranged along the axial inner side. The inner diameter of the semi-circular hole 74 is equivalent to the outer diameter of the mating part 61, and the outer diameter of the arc-shaped hole 76 is also equivalent to the outer diameter of the mating part 61, but the arc-shaped hole 76 is only an incomplete circular hole of a fraction, that is, only a part of the mating part 61 can be attached to the inner wall of the arc-shaped hole 76.

[0043] As Figure 4 shown, when the tapered head 62 is fitted in the tapered hole 75, a part of the mating part 61 extends out of the end of the clamping arm 4, and a part of the mating part 61 is arranged in the positioning hole 42 and the semi-circular hole 74. The springs 35 make the two adjusting blocks 7 approach each other and be received in the chute 41. In this case, the two adjusting blocks 7 in the same chute 41 are close to each other, so that the two adjusting blocks 7 on the inner sides of the two clamping arms 4 are far from each other, and the end of the filter bag can be placed for clamping; and the two adjusting blocks 7 on the outer sides of the two clamping arms 4 approach each other and are received in the chute 41, and the width of the clamping arm 4 is the smallest. At this time, the width of the clamping arm 4 is the width of the two clamping arms 4.

[0044] As Figure 5 shown, when the mating part 61 is fitted in the arc-shaped hole 76, transitioning from the positioning hole 42 to the arc-shaped hole 76, the tapered head 62 reaches the position when it abuts against the fixing block 34, and the mating part 61 presses the two adjusting blocks 7 in the same chute 41 to move away from each other and extend out of the chute 41. In this case, the two adjusting blocks 7 in the same chute 41 are far from each other, so that the two adjusting blocks 7 on the inner sides of the two clamping arms 4 approach each other to clamp the filter bag placed between the two clamping arms 4; and the two adjusting blocks 7 on the outer sides of the two clamping arms 4 are far from each other, and the width of the clamping arm 4 is the largest. At this time, the width of the clamping arm 4 is the width of the two adjusting blocks 7 on the outer sides of the two clamping arms 4.

[0045] Such a design can increase the width of the clamping arm 4 while clamping the filter bag. After the winding is completed, the clamping of the filter bag is released and the width of the clamping arm 4 is reduced at the same time, so as to also release the tension state of the filter bag, and thus the stable, firm and reliable winding of the filter bag and the labor-saving and easy unloading can be realized.

[0046] Further, a stepped groove 71 is provided at one end of the adjusting block 7. The stepped groove 71 is cooperatively provided with the fixed block 34. When the stepped groove 71 is in close contact with the fixed block 34, the two adjusting blocks 7 in the same sliding groove 41 are in close contact with each other. In this way, the adjusting block 7 can be more stably limited in the sliding groove 41. At the same time, the end is positioned by the engaging portion 61 of the pin 6, so that the entire adjusting block 7 can be stably arranged in the sliding groove 41.

[0047] Further, an installation groove 73 is provided in the adjusting block 7. The installation groove 73 is arranged between the two sliding holes 72, and the spring 35 is arranged in the installation groove 73, and the spring 35 can be accommodated.

[0048] Embodiment 2

[0049] Further, this embodiment further designs a driving device for driving the turntable 3 to rotate.

[0050] The driving device includes a rotating shaft 2 and a lead screw 21. One end of the rotating shaft 2 is connected with the lead screw 21, and the lead screw 21 is connected with the turntable 3.

[0051] The filter bag taking-out device of the present invention further includes a pusher plate 9. The pusher plate 9 includes two pusher blocks 91 in a V shape. The V-shaped design can further reduce the weight. The two pusher blocks 91 are symmetrically arranged. Arc-shaped blocks 92 are respectively provided at one ends of the two pusher blocks 91, and the two pusher blocks 91 are arranged at intervals. The pusher plate 9 is sleeved outside the two clamping arms 4 and the guide rod 33. When the pusher plate 9 moves horizontally, it will not interfere with the guide rod 33 and the clamping arm 4. The pusher plate 9 is connected with a telescopic mechanism for driving the pusher plate 9 to reciprocate axially along the clamping arm 4. The arrangement of the pusher plate 9 can push out the wound filter bag, so that the filter bag is separated from the clamping arm 4 and the adjusting block 7, realizing rapid removal.

[0052] Further, both sides of the clamping arm 4 are provided as arc-shaped surfaces, one side of the adjusting block 7 is provided as an arc-shaped surface, and the limiting groove 93 is provided as an arc-shaped groove.

[0053] Further, two limiting grooves 93 are provided on the inner wall of the pusher block 91 at a fixed distance from each other, and both sides of the clamping arm 4 are cooperatively arranged in the limiting grooves 93. With such a design, the guiding sliding limit can be realized through the cooperation of the limiting groove 93 and the clamping arm 4, thereby also ensuring the axial positions of the clamping arm 4 and the pusher plate 9.

[0054] Further, a lead screw nut 8 is fitted and connected to the lead screw 21. A connecting ring 82 is rotatably arranged on one side of the lead screw nut 8 through a second bearing 84. A plurality of connecting rods 83 are arranged on the circumference of the connecting ring 82. The connecting rods 83 pass through the through holes 31 of the turntable 3 and are connected to the pushing plate 9. The rotating shaft 2 is rotatably arranged in the chassis 1 through a first bearing 11. One end of the rotating shaft 2 extends to the outside of the chassis 1. A guide rail 5 is arranged on one side of the chassis 1. A guide rail groove 51 is arranged in the guide rail 5. A slider 52 is slidably arranged on the guide rail groove 51. The slider 52 is detachably connected to the lead screw nut 8 through a connecting member.

[0055] Furthermore, the connecting member is a screw rod 54. The slider 52 is internally hollow and provided with a through groove 53. A screw rod 54 is threadedly connected to the upper end of the slider 52. A plurality of sleeves 81 are evenly distributed on the outer wall of the lead screw nut 8. One end of the screw rod 54 is inserted into the inside of the sleeve 81.

[0056] As Figure 5 shown, at this time, the pushing plate 9 is close to the turntable 3. The pushing plate 9 can act as a limiting function for limiting the position of the filter bag winding. That is, when the filter bag is wound around the outer walls of the clamping arms 4 and the adjusting blocks 7, one side of the wound filter bag is closely arranged against the pushing plate 9. During winding, the turntable 3 rotates, the screw rod 54 disengages from the sleeve 81, the lead screw 21 and the lead screw nut 8 rotate synchronously, and the turntable 3 also rotates. The pushing plate 9 does not move axially relative to the clamping arms 4.

[0057] As Figure 5 shown, if the filter bag has been wound up at this time, the turntable 3 rotates to align the screw rod 54 and the sleeve 81, and the screw rod 54 is screwed into the sleeve 81. Then the rotating shaft 2 rotates again, the lead screw 21 rotates, the lead screw nut 8 does not rotate but moves, the turntable 3 also rotates, and the pushing plate 9 moves axially relative to the clamping arms 4 to horizontally push out the wound filter bag from the clamping arms 4 and the adjusting blocks 7.

[0058] With this design, only one driving device is needed. For example, a motor is set to drive the rotating shaft 2 to rotate, so as to realize the winding operation of the filter bag and the pushing out and unloading of the filter bag. The overall device is more compact, and the winding and unloading operations of the filter bag can be realized more conveniently.

[0059] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
