Description

Technical Field

[0001] The present invention relates to the technical field of dust collection, and particularly relates to a dust collection device for drying polyester fibers. Background Art

[0002] In the production process of polyester fibers, a large amount of dust is generated during the drying process. These dusts not only pollute the production environment but also seriously threaten the health of operators. Long-term inhalation may cause respiratory diseases such as pneumoconiosis. Traditional dust collection devices have many problems when dealing with the dust generated from the drying of polyester fibers.

[0003] Common bag filters have a certain filtering effect on fine dust. However, polyester fiber dust is easily adhered to the surface of the filter bags, resulting in blockage of the filter bags. This not only requires frequent replacement of the filter bags, increasing production costs and polluting the environment, but also the collected dust is usually in a loose state, occupying a large amount of storage space. Moreover, dust leakage will occur during the replacement process, and it is extremely easy to fly again during transportation and disposal, causing secondary pollution.

[0004] Chinese Patent Publication No. CN218687589U discloses an efficient dust collection device for drying polyester fibers, including a vertical frame. A collection shell is fixedly connected to the vertical frame. An impact component is provided at the upper end of the collection shell. A filter bag component is installed and connected inside the collection shell. A horizontal plate is provided at one end of the vertical frame. One end of the sliding plate is fixedly connected to the sliding sleeve. The efficient dust collection device for drying polyester fibers provided by this patent ensures good sealing inside the device by using a filter screen frame plate with good passability, effectively controlling the loss of dust and avoiding environmental pollution caused by raw material overflow. By simultaneously rotating the rotating shafts on the two collection boxes in the reverse direction, the openings of the two collection boxes can be alternately in the open state, ensuring that the work of collecting dust can continue, thereby effectively collecting the dust. However, in the actual use process of the above device, the dust still flies everywhere during the collection and subsequent treatment processes, and the harm of the dust to the working environment and operators is relatively large.

Overall, a process of dust filtering, compaction and anti-flying is formed, which reduces the dust emission while improving the dust collection effect and reducing the harm of dust to the working environment and operators.

[0018] 3. In the present invention, through the cooperation of the first filtering component and the second filtering component, the extrusion block is driven by the reciprocating rod to reciprocally and intermittently extrude the second water sac. This way enables the sponge to always maintain a wet state, provides a continuous wetting effect for the two filter plates, maintains the adsorption capacity of the filter plates for dust, and improves the overall filtering effect.

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with the detailed implementation manners.

[0022] Example 1, as Figure 1-2As shown in the figure, a dust collection device for drying polyester fibers includes a box body 1. An air outlet 11 is arranged at the upper end of the box body 1. A fan is arranged inside the air outlet 11. A maintenance opening 12 is arranged at the front end of the box body 1. A maintenance opening 13 is arranged above the maintenance opening 12. The maintenance opening 12 and the maintenance opening 13 can be used to replace or repair the internal structure of the box body 1. An air inlet 14 is arranged at the rear end of the box body 1 and at the middle position. A first filter component 2 is arranged inside the box body 1. A dust collection component 3 is arranged below the first filter component 2. A limiting component 4 is arranged below the first filter component 2. A spray component 5 is arranged on the right side of the dust collection component 3. A second filter component 6 is arranged above the first filter component 2.

[0023] Therefore, in this solution, most of the particles in the dust are separated by the first filter component 2 first, and then the remaining fine particles in the dust are adsorbed by continuous wetting of the second filter component 6. The two filtering steps improve the collection efficiency, reduce dust emissions. At the same time, when the first filter component 2 separates the dust, the dust collection component 3, the limiting component 4 and the spray component 5 collect, extrude and cool the dust synchronously, inhibit the dust from flying, facilitate subsequent collection and treatment, and also reduce the risk of dust explosion and the pollution of dust to the environment.

[0024] Embodiment 2: On the basis of Embodiment 1, this embodiment is to achieve the effect of synchronously filtering, compacting and preventing dust from flying.

[0025] Refer to Figure 1-10 As shown in the figure, the first filter component 2 includes a first fixing plate 21 fixedly connected to the lower side of the inner surface of the box body 1. A motor 22 is fixedly installed at the lower end of the first fixing plate 21. The output end of the motor 22 is fixedly connected to a first gear 221. The outer surface of the first gear 221 is meshed with a second gear 222. The upper ends of the first gear 221 and the second gear 222 are both fixedly connected to a first rotating shaft 23. The outer surfaces of the two first rotating shafts 23 are both fixedly connected to a belt transmission mechanism 24. The inner surface of the box body 1 is fixedly connected to a mounting plate 27. The upper ends of the two first rotating shafts 23 are jointly rotatably connected to the mounting plate 27.

[0026] The above-mentioned belt transmission mechanism 24 is composed of two belt pulleys with different diameters and a belt. Among them, the belt pulley fixedly connected to the first rotating shaft 23 has a larger diameter, and the belt pulley fixedly connected to the second rotating shaft 26 has a smaller diameter. Therefore, the rotation speed of the second rotating shaft 26 is faster.

[0027] Refer to Figure 3-5, protective shells 25 are provided on the outer surfaces of both belt transmission mechanisms 24. The rear ends of the two protective shells 25 are fixedly connected to the rear side wall of the inner surface of the box body 1 together. The outer surfaces of the two first rotating shafts 23 are rotatably connected to the inner surfaces of the protective shells 25. At the ends of the two belt transmission mechanisms 24 far from the first rotating shafts 23, second rotating shafts 26 are fixedly connected respectively. Two air inlets II 271 are formed on the outer surface of the mounting plate 27. At the upper ends of the two second rotating shafts 26, connecting frames 261 are fixedly connected respectively. Conical centrifugal cylinders 28 are fixedly connected to the outer surfaces of the two connecting frames 261. At the upper ends of the two conical centrifugal cylinders 28, air outlets II 281 are fixedly connected respectively. The air inlet I 14 is located at the middle position between the two air inlets II 271. A dust discharge hopper 29 is fixedly connected to the lower side of the mounting plate 27.

[0028] Furthermore, the upper end of the protective shell 25 mentioned above is a rounded pointed shape, effectively avoiding the situation where the dust slipping down from the inner wall of the conical centrifugal cylinder 28 accumulates on the protective shell 25.

[0029] Among them, a spiral baffle is arranged inside the conical centrifugal cylinder 28, which helps to make the air flow rotate.

[0030] Furthermore, first start the fan inside the air outlet I 11, and then start the motor 22. The motor 22 will drive the first gear 221 to rotate and mesh with the second gear 222. Subsequently, the two first rotating shafts 23 are also driven to rotate. The rotation of the two first rotating shafts 23 will be transmitted to the two second rotating shafts 26 through the belt transmission mechanism 24, causing the two second rotating shafts 26 to rotate together. During the rotation of the two second rotating shafts 26, the two conical centrifugal cylinders 28 will be driven to rotate rapidly together; Then the gas during the drying of the polyester fiber will enter the interior of the box body 1 from the air inlet I 14 and enter the conical centrifugal cylinders 28 respectively through the two air inlets II 271. The gas entering the conical centrifugal cylinder 28 is guided and constrained by the spiral baffle inside the cylinder, enabling the air flow to obtain a tangential velocity and form a rotating air flow similar to a cyclone. The dust particles in the gas also move in a circular motion along with the gas. Under the action of the centrifugal force, the dust particles will be thrown outward. Since the centrifugal force received by the dust particles is much greater than the viscous resistance of the gas to it, the dust particles will gradually move towards the inner wall of the conical centrifugal cylinder 28. When the dust particles contact the inner wall, due to inertia, they will slide down along the inner wall of the conical centrifugal cylinder 28 and finally fall into the dust collection device at the bottom from the dust discharge hopper 29. The lighter gas continues to rotate inside the conical centrifugal cylinder 28 and finally is discharged from the air outlet II 281 at the top of the conical centrifugal cylinder 28, thus realizing the separation of dust and gas.

[0031] Refer to Figure 5-10, the dust collection assembly 3 includes a semi-gear 31 fixedly connected to the lower ends of the outer surfaces of the two first rotating shafts 23. A first limiting rod 32 is fixedly connected to the inner surface of the box body 1. A first rack 33 is slidably connected to the outer surface of the first limiting rod 32. The outer surfaces of the two semi-gears 31 are jointly meshed with the first rack 33. A pushing block 34 is fixedly connected to the right side of the upper end of the first rack 33. A second fixing plate 35 is fixedly connected to the upper side of the first fixing plate 21. The outer surface of the second fixing plate 35 is slidably connected to a sliding groove 351, and the sliding groove 351 is formed on the outer surface of the second fixing plate 35.

[0032] A first connecting rod 36 is rotatably connected to the left side of the upper end of the second fixing plate 35. A four-bar linkage 37 is rotatably connected to the outer surface of the first connecting rod 36. A second connecting rod 38 is rotatably connected to the right end of the four-bar linkage 37. Two second limiting rods 39 are fixedly connected to the inner surface of the box body 1. The upper end of the four-bar linkage 37 is rotatably connected to four first sliding blocks 310. Limiting plates 311 are fixedly connected to the upper ends of the four first sliding blocks 310. A second sliding block 314 is rotatably connected to the upper end of the second connecting rod 38. A limiting plate 315 is fixedly connected to the upper end of the second sliding block 314. The left end of the pushing block 34 is fixedly connected to the limiting plate 315. Two springs 312 are fixedly connected to the upper ends of both the limiting plate 315 and the limiting plates 311. Two water boxes 313 are fixedly connected to the upper ends of the four springs 312.

[0033] Specifically, the second limiting rods 39 above can limit the limiting plates 311 and the second sliding block 314, so that the four limiting plates 311 and the second sliding block 314 slide back and forth stably.

[0034] Furthermore, a dust collection bag is placed between the limiting plate 311 and the limiting plate 315. Holes are formed on both the left and right sides of the dust collection bag. When installing the dust collection bag, first ensure that the equipment is shut down, and then open the second maintenance opening 13. At this time, the four-bar linkage 37 is in an extended state. Hang the left end of the dust collection bag on the first hook 41, pass through the lower ends of the two spray heads 53, and connect the right end to the second hook 411. Then press down the part in the middle of the limiting plate 311 to make the dust collection bag sink between the four limiting plates 311 and one limiting plate 315.

[0035] Furthermore, when the first gear 221 meshes with the second gear 222, it can synchronously drive the two half-gears 31 to rotate in opposite directions, thereby driving the first rack 33 to reciprocate. When the first rack 33 reciprocates, it will drive the second limiting plate 315 to move. During the movement, the second limiting plate 315 will pull the second connecting rod 38, the four-bar linkage 37 and the first connecting rod 36 to expand or fold, thereby driving the distance between the four first sliding blocks 310 and the distance between the second limiting plate 315 and the leftmost first limiting plate 311 to increase or decrease, so as to fold or unfold the dust collection bag. Among them, moving to the left is folding, and moving to the right is unfolding. Thus, the collected dust can be compacted, reducing the volume of the dust, increasing the capacity of the dust collection bag, and reducing the frequency of replacing the dust collection bag.

[0036] The limiting component 4 includes a first hook 41 fixedly connected to the lower part of the left inner surface of the box body 1. A connecting block 42 is fixedly connected to the front end of the first rack 33. A second rack 43 is fixedly connected to the front end of the connecting block 42. A third gear 44 is meshed with the outer surface of the second rack 43. A third rotating shaft 45 is fixedly connected to the inner surface of the third gear 44. The lower end of the third rotating shaft 45 is rotatably connected to the bottom of the inner surface of the box body 1. The upper end of the third rotating shaft 45 passes through the inner surface of the second fixing plate 35 and is fixedly connected to a bevel gear transmission group 46.

[0037] Furthermore, the bevel gear transmission group 46 mentioned above is composed of two meshing bevel gears, which can change the rotation direction.

[0038] A fixed block 47 is fixedly connected to the lower part of the right inner surface of the box body 1. A rotating rod 48 is fixedly connected to the rear end of the bevel gear transmission group 46. The outer surface of the rotating rod 48 is rotatably connected to the fixed block 47. Four rope pulleys 49 are arranged on the outer surface of the rotating rod 48. A connecting plate 410 is fixedly connected to the lower ends of the four rope pulleys 49. A second hook 411 is fixedly connected to the lower end of the connecting plate 410.

[0039] Furthermore, during the process of the second sliding block 314 moving to the right, the second connecting rod 38, the four-bar linkage 37 and the first connecting rod 36 will expand to the right together. Among them, the leftmost first limiting plate 311 moves the shortest distance, while the second limiting plate 315 moves the largest distance back and forth. However, it should be noted that the distance of the second limiting plate 315 moving to the left will not exceed the position where the dust drops from the lower end of the dust discharge hopper 29 at most.

[0040] When the second limiting plate 315 mentioned above moves to the left, the dust collection bag will also be driven to contract to the left. At this time, the second limiting plate 315 will drive the rotating rod 48 to rotate clockwise through other structures, making the rope on the rope pulley 49 longer. Therefore, the second hook 411 hanging on the right end of the dust collection bag will also move to the left together, so that the distance between the right end of the second limiting plate 315 and the second hook 411 always remains unchanged. For reference, please refer to the appendix Figure 9; Conversely, when the second limiting plate 315 moves to the right, the whole dust collection bag is unfolded and moves to the right. At this time, the second hook 411 will also retract accordingly. Refer to the appendix Figure 10 .

[0041] During the whole process, when the dust collection bag reciprocates and contracts, its left and right ends are always in a state of being pulled, neither detaching nor causing the middle part to shrink upward due to excessive pulling force when the dust collection bag is squeezed.

[0042] Furthermore, when the first rack 33 moves to the left, it will drive the connecting block 42 and the second rack 43 to move together, causing the second rack 43 to mesh with the third gear 44, driving the third gear 44 to rotate counterclockwise. The third gear 44 drives the third rotating shaft 45 and the bevel gear transmission group 46 to rotate, causing the rotating rod 48 to rotate clockwise. Thus, when the second limiting plate 315 moves to the left and starts to squeeze the dust collection bag, the rope pulley 49, the connecting plate 410 and the second hook 411 start to release the rope. Finally, the second hook 411 always follows the right end of the dust-proof bag and maintains a certain limiting effect. In this way, the right end of the dust collection bag can always be pulled by the second hook 411 to prevent the right side of the dust collection bag from falling off, and at the same time, the pulling force on the right end when the dust collection bag contracts is reduced, avoiding the situation that the bag in the middle of the first limiting plate 311 moves upward too much when the dust collection bag is squeezed.

[0043] The spray assembly 5 includes a first water bag 51 fixedly connected to the right side wall of the inner surface of the box body 1. The left end of the first water bag 51 is fixedly connected to the second limiting plate 315. A first water pipe 52 is fixedly connected to the upper end of the first water bag 51. One end of the first water pipe 52 far from the first water bag 51 is fixedly connected to two water boxes 313. Spray heads 53 are arranged on the mutually approaching surfaces of the two water boxes 313. A second water pipe 54 is fixedly connected to the right end of the first water bag 51. One end of the second water pipe 54 far from the first water bag 51 is fixedly connected to a water tank 55. The left end of the water tank 55 is fixedly connected to the box body 1.

[0044] Further, check valves are arranged inside both the first water pipe 52 and the second water pipe 54. The check valve inside the first water pipe 52 can only discharge water outward and cannot absorb water, while the check valve inside the second water pipe 54 can only absorb water into the first water bag 51 and cannot drain water.

[0045] Among them, the liquid stored in the water tank 55 contains surfactant SDS, which can reduce the surface tension of the liquid, making it easier for water to wet the polyester fiber dust particles, preventing the dust particles from re-agglomerating, and improving the filtration uniformity.

[0046] Furthermore, when the second limiting plate 315 is driven by the pushing block 34 to move to the right to unfold the dust collection bag, the second limiting plate 315 will squeeze the first water sac 51. The water in the first water sac 51 will be transported through the first water pipe 52 to the water box 313, and then sprayed from the spray head 53 to wet the dust in the dust collection bag, which can not only cool down but also inhibit the flying of dust, and is more conducive to the subsequent collection and treatment of dust. When the second limiting plate 315 moves to the left to drive the first water sac 51 to open, the first water sac 51 will absorb water from the water tank 55 through the second water pipe 54 for replenishment.

[0047] Therefore, in this solution, the first filtering component 2 first uses centrifugal force to preliminarily filter the dust generated by the gas during the drying of polyester fibers. Subsequently, through the cooperation of the dust collection component 3 and the limiting component 4, the dust will fall into the dust collection bag and be reciprocally squeezed, thereby compacting the dust, reducing the volume of the dust, improving the utilization of the dust collection bag, and intermittently spraying during the squeezing process, enabling the dust to be fully wetted and quickly cooled, effectively inhibiting the flying of dust during subsequent dust treatment. Overall, a process of dust filtration, compaction, and anti-flying is formed, reducing dust emissions while improving the dust collection effect and reducing the harm of dust to the working environment and operators.

[0048] Embodiment 3. On the basis of Embodiment 1 and Embodiment 2, this embodiment aims to achieve the effect of continuously wetting the filter plate 61 to maintain the dust adsorption capacity.

[0049] Refer to Figure 1 、 Figure 2 、 Figure 11-12 The second filtering component 6 includes two filter plates 61 arranged at the upper part of the inner surface of the box body 1. A sponge 62 is arranged at the middle position between the two filter plates 61. The lower end of the lower filter plate 61 is fixedly connected with a second water sac 63. The upper end of the right rotating shaft 23 is fixedly connected with a reciprocating rod 64. An extrusion block 65 is slidably connected to the outer surface of the reciprocating rod 64. The upper end of the mounting plate 27 is fixedly connected with a limiting column 66. The upper end of the limiting column 66 is fixedly connected with the lower end of the lower filter plate 61. The left side of the inner surface of the extrusion block 65 is slidably connected with the limiting column 66. The upper end of the extrusion block 65 contacts the second water sac 63.

[0050] Specifically, the above-mentioned limiting column 66 can limit the extrusion block 65 to move up and down stably, and intermittently squeeze the second water sac 63.

[0051] Among them, the material of the sponge 62 is hydrophilic polyurethane sponge, which is hydrolysis-resistant and mildew-resistant.

[0052] Further, the filter plate 61 is composed of a film-coated polyester filter cloth and a stainless steel wire mesh. The film-coated polyester filter cloth can accurately capture fine dust such as PM2.5, and the surface of the film-coated filter cloth is smooth and hydrophobic. Even when combined with a water spraying and wetting device, the water film evenly covers but does not expand the fibers, avoiding hole blockage. The stainless steel wire mesh provides a strong support to prevent the filter cloth from deforming or tearing, extending its service life. The film-coated filter cloth is anti-aging and not easily damaged in a long-term wet environment. The filter plate 61 can be installed and disassembled, and these are all very mature existing technologies, so the disassembly and installation methods will not be elaborated in detail in this case.

[0053] A water pipe three 67 is fixedly connected to the front end of the second water bag 63. The water pipe three 67 extends into the interior of the sponge 62 and is evenly distributed. A number of round holes are formed on the outer surface of the water pipe three 67. A water pipe four 68 is fixedly connected to the right end of the second water bag 63. The lower end of the water pipe four 68 is fixedly connected to the water tank 55.

[0054] The reciprocating rod 64 mentioned above is a ball screw mechanism in the prior art; Furthermore, when the first rotating shaft 23 rotates, it will drive the reciprocating rod 64 to rotate together, causing the extrusion block 65 to slide up and down. When the extrusion block 65 rises to the position of the second water bag 63, it will squeeze the second water bag 63, causing the water inside the second water bag 63 to spray out from the holes on the water pipe three 67, uniformly wetting the sponge 62, thereby ensuring that the two filter plates 61 are always in a wet state and adsorbing the remaining fine particulate dust in the gas.

[0055] Therefore, through the cooperation of the first filter assembly 2 and the second filter assembly 6 in this solution, the extrusion block 65 realizes the reciprocating intermittent extrusion action of the second water bag 63 driven by the reciprocating rod 64. This method enables the sponge 62 to always maintain a wet state, provides a continuous wetting effect for the two filter plates 61, maintains the dust adsorption ability of the filter plates 61, and improves the overall filtering effect.

[0056] It should be particularly noted that the specific installation method of the fan and the motor 22, the connection method of the circuit, and the control method adopted in the present invention are all conventional designs, and will not be elaborated in detail in the present invention.

Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention.
