Description

Technical Field

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

[0002] During the polyester fiber production process, a large amount of dust is generated during the drying process. This dust not only pollutes the production environment, but also seriously threatens the health of operators. Long-term inhalation may lead to respiratory diseases such as pneumoconiosis. Traditional dust collection devices have many problems when dealing with the dust generated by polyester fiber drying.

[0003] Although common bag dust collectors have a certain filtering effect on fine dust, polyester fiber dust easily adheres to the surface of the bags, causing the bags to become clogged. This not only requires frequent bag replacement, which increases production costs and pollutes the environment, but the collected dust is usually in a loose state, taking up a large amount of storage space. Dust leakage may also occur during the replacement process, and it is very easy to fly again during transportation and disposal, causing secondary pollution.

[0004] Chinese patent announcement number CN218687589U discloses a high-efficiency polyester fiber drying dust collection device, comprising a stand, a collection shell fixedly connected to the stand, a counter-balance assembly provided at the upper end of the collection shell, a filter bag assembly installed and connected inside the collection shell, a horizontal plate provided at one end of the stand, and one end of the sliding plate fixedly connected to the sliding sleeve. The high-efficiency polyester fiber drying dust collection device provided by this patent ensures a good sealing effect inside the device by utilizing a filter frame plate with good permeability, effectively controls the loss of dust, and avoids environmental pollution caused by spillage of raw materials; by simultaneously rotating the rotating shafts on the two collection boxes in opposite directions, the box openings of the two collection boxes can be alternately opened, ensuring that the dust collection work can be carried out continuously, thereby achieving effective dust collection;

[0035] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0036] Example 1, as Figure 1-2 As shown, a dust collection device for drying polyester fibers comprises a box body 1, an air outlet 11 is provided at the upper end of the box body 1, a fan is provided inside the air outlet 11, a maintenance port 12 is provided at the front end of the box body 1, a maintenance port 2 13 is provided on the upper side of the maintenance port 12, and the maintenance port 12 and the maintenance port 2 13 can be used to replace or repair the internal structure of the box body 1, an air inlet 14 is provided at the rear end and in the middle position of the box body 1, a filter component 2 is provided inside the box body 1, a dust collecting component 3 is provided on the lower side of the filter component 2, a limiting component 4 is provided on the lower side of the filter component 2, a spray component 5 is provided on the right side of the dust collecting component 3, and a filter component 2 6 is provided on the upper side of the filter component 2.

[0037] Therefore, this solution first separates most of the particles in the dust through the filter component 1 2, and then uses the filter component 2 6 to continuously wet and adsorb the remaining fine particles in the dust. The two filtering steps improve the collection efficiency and reduce dust emissions. At the same time, when the filter component 1 2 separates the dust, the dust collection component 3, the limit component 4 and the spray component 5 synchronously collect, squeeze and cool the dust, suppressing the flying of dust, facilitating subsequent collection and processing, while also reducing the risk of dust explosion and reducing the pollution of dust to the environment.

[0038] Embodiment 2: Based on embodiment 1, this embodiment is to achieve the effects of dust filtration, compaction and anti-flying simultaneously.

[0039] See Figure 1-10 The filter assembly 2 includes a fixing plate 21 fixedly connected to the lower side of the inner surface of the box body 1, and a motor 22 is fixedly installed on the lower end of the fixing plate 21. The output end of the motor 22 is fixedly connected to a gear 221, and the outer surface of the gear 221 is meshed with the gear 2 222. The upper ends of the gear 1 221 and the gear 2 222 are fixedly connected to a rotating shaft 23, and the outer surfaces of the two rotating shafts 23 are fixedly connected to a belt transmission mechanism 24. The inner surface of the box body 1 is fixedly connected to a mounting plate 27, and the upper ends of the two rotating shafts 23 are rotatably connected to the mounting plate 27.

[0040] The belt transmission mechanism 24 mentioned above is composed of two pulleys and belts with different diameters. The pulley fixedly connected to the rotating shaft 1 23 has a larger diameter, and the pulley fixedly connected to the rotating shaft 2 26 has a smaller diameter, so the rotation speed of the rotating shaft 2 26 is faster.

[0041] See Figure 3-5, the outer surfaces of the two belt transmission mechanisms 24 are provided with protective shells 25, and 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. The outer surfaces of the two rotating shafts 23 are rotatably connected to the inner surface of the protective shell 25, and the ends of the two belt transmission mechanisms 24 away from the rotating shaft 1 23 are fixedly connected to the rotating shaft 2 26. The outer surface of the mounting plate 27 is provided with two air inlet ports 271, and the upper ends of the two rotating shafts 26 are fixedly connected to the connecting frame 261. The outer surfaces of the two connecting frames 261 are fixedly connected to the conical centrifugal cylinders 28, and the upper ends of the two conical centrifugal cylinders 28 are fixedly connected to the air outlet port 281. The air inlet port 14 is located in the middle position of the two air inlet ports 271, and the lower side of the mounting plate 27 is fixedly connected to the dust hopper 29.

[0042] Furthermore, the upper end of the protective shell 25 is rounded and pointed, which effectively prevents the dust sliding down from the inner wall of the conical centrifugal cylinder 28 from accumulating on the protective shell 25 .

[0043] The conical centrifugal cylinder 28 is provided with a spiral baffle inside to help rotate the airflow.

[0044] Then, the fan inside the air outlet 11 is started first, and then the motor 22 is started. The motor 22 drives the gear 1 221 to rotate so that it meshes with the gear 2 222. Subsequently, the two rotating shafts 1 23 are also driven to rotate. The rotation of the two rotating shafts 1 23 is transmitted to the two rotating shafts 26 via the belt transmission mechanism 24, so that the two rotating shafts 26 rotate together. During the rotation of the two rotating shafts 26, the two conical centrifugal cylinders 28 are driven to rotate rapidly together.

[0045] Then the gas during the drying of the polyester fiber will enter the interior of the box 1 from the air inlet 14, and enter the conical centrifugal cylinder 28 through the two air inlet 271 respectively. The gas entering the conical centrifugal cylinder 28 is guided and constrained by the spiral baffle in the cylinder, so that the airflow obtains tangential velocity, forming a rotating airflow similar to a cyclone, and the dust particles in the gas also move in a circular motion with the gas. Under the action of centrifugal force, the dust particles will be thrown outward. Since the centrifugal force on the dust particles is much greater than the viscous resistance of the gas to it, the dust particles will gradually move toward the inner wall of the conical centrifugal cylinder 28. When the dust particles contact the inner wall, due to inertia, they will slide along the inner wall of the conical centrifugal cylinder 28, and finally fall into the dust collecting device at the bottom from the dust hopper 29, while the lighter gas continues to rotate in the conical centrifugal cylinder 28, and is finally discharged from the air outlet 2 281 at the top of the conical centrifugal cylinder 28, thereby realizing the separation of dust and gas.

[0046] See Figure 5-10The dust collecting assembly 3 includes a half gear 31 fixedly connected to the lower end of the outer surface of the two rotating shafts 23, a limit rod 32 fixedly connected to the inner surface of the box body 1, and a rack 33 is slidably connected to the outer surface of the limit rod 32. The outer surfaces of the two half gears 31 are jointly meshed with the rack 33, and a pushing block 34 is fixedly connected to the right side of the upper end of the rack 33. A fixed plate 2 35 is fixedly connected to the upper side of the fixed plate 21, and the outer surface of the fixed plate 2 35 is slidably connected to the sliding groove 351. The outer surface of the fixed plate 2 35 is provided with a sliding groove 351.

[0047] The left side of the upper end of the fixed plate 2 35 is rotatably connected to the connecting rod 1 36, the outer surface of the connecting rod 1 36 is rotatably connected to the four-link rod 37, the right end of the four-link rod 37 is rotatably connected to the connecting rod 2 38, the inner surface of the box body 1 is fixedly connected to two limit rods 2 39, the upper end of the four-link rod 37 is rotatably connected to four sliding blocks 1 310, the upper ends of the four sliding blocks 1 310 are all fixedly connected to the limit plate 1 311, the upper end of the connecting rod 2 38 is rotatably connected to the sliding block 2 314, the upper end of the sliding block 2 314 is fixedly connected to the limit plate 2 315, the left end of the pushing block 34 is fixedly connected to the limit plate 2 315, the upper ends of the limit plate 2 315 and the limit plate 1 311 are both fixedly connected to two springs 312, and the upper ends of the four springs 312 are jointly fixedly connected to two water boxes 313.

[0048] Specifically, the above-mentioned limiting rod 2 39 can limit the limiting plate 1 311 and the sliding block 2 314, so that the four limiting plates 1 311 and the sliding block 2 314 can slide back and forth stably.

[0049] Furthermore, a dust bag is placed between the limit plate 1 311 and the limit plate 2 315 , and holes are opened on the left and right sides of the dust bag. When installing the dust bag, first ensure that the equipment is shut down, and then open the maintenance port 2 13. At this time, the four-link 37 is in the unfolded state. The left end of the dust bag is hung on the hook 1 41, passed through the lower ends of the two spray heads 53, and the right end is connected to the hook 2 411. Then, the part located in the middle of the limit plate 1 311 is pressed down, so that the dust bag is trapped between the four limit plates 1 311 and one limit plate 2 315.

[0050] Furthermore, when gear 1 221 and gear 2 222 are engaged, they can synchronously drive the two half gears 31 to rotate in opposite directions, thereby driving the rack 1 33 to move back and forth. When the rack 1 33 moves back and forth, it will drive the limit plate 2 315 to move. During the movement, the limit plate 2 315 will pull the connecting rod 2 38, the four-link rod 37 and the connecting rod 1 36 to expand or close together, thereby driving the distance between the four sliding blocks 1 310 and the distance between the limit plate 2 315 and the limit plate 1 311 on the far left to expand or shrink, so that the dust bag is closed or expanded, wherein moving to the left is closing, and moving to the right is expanding, so that the collected dust can be compacted, the volume of the dust is reduced, the dust bag's capacity is increased, and the frequency of replacing the dust bag is reduced.

[0051] The limiting assembly 4 includes a hook 1 41 fixedly connected to the lower part of the left side wall of the inner surface of the box body 1, the front end of the rack 1 33 is fixedly connected to the connecting block 42, the front end of the connecting block 42 is fixedly connected to the rack 2 43, the outer surface of the rack 2 43 is meshed with the gear 3 44, the inner surface of the gear 3 44 is fixedly connected to the rotating shaft 3 45, the lower end of the rotating shaft 3 45 is rotatably connected to the bottom of the inner surface of the box body 1, and the upper end of the rotating shaft 3 45 passes through the inner surface of the fixed plate 2 35 and is fixedly connected to the bevel gear transmission group 46.

[0052] Furthermore, the bevel gear transmission set 46 is composed of two bevel gears meshing with each other, which can change the direction of rotation.

[0053] A fixed block 47 is fixedly connected to the lower right side wall of the inner surface of the box body 1, and 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 pulleys 49 are provided on the outer surface of the rotating rod 48. The lower ends of the four pulleys 49 are fixedly connected to a connecting plate 410, and the lower end of the connecting plate 410 is fixedly connected to a hook 2 411.

[0054] Furthermore, when the sliding block 2 314 moves to the right, the connecting rod 2 38, the four-link 37 and the connecting rod 1 36 will expand to the right together, among which the limit plate 1 311 on the far left moves the smallest distance, and the limit plate 2 315 moves back and forth the largest distance. However, it should be noted that the maximum distance that the limit plate 2 315 moves to the left will not exceed the position where the dust falls from the lower end of the dust hopper 29.

[0055] When the second limiting plate 315 moves to the left, the dust bag will also be driven to retract to the left. At this time, the second limiting plate 315 will drive the rotating rod 48 to rotate clockwise through other structures to make the rope on the rope wheel 49 longer, so the second hook 411 hanging on the right end of the dust 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. Figure 9On the contrary, when the limiting plate 315 moves to the right, the dust bag is unfolded and moves to the right, and the hook 411 will also retract together. Figure 10 .

[0056] The whole process ensures that the left and right ends of the dust bag are always in a pulled state when it reciprocates and contracts, and it will neither fall off nor cause the middle part to shrink upward due to excessive pulling force when the dust bag is squeezed.

[0057] Furthermore, when rack 1 33 moves to the left, it will drive connecting block 42 and rack 2 43 to move together, so that rack 2 43 is meshed with gear 3 44, driving gear 3 44 to rotate counterclockwise, and gear 3 44 drives rotating shaft 3 45 and bevel gear transmission group 46 to rotate, so that rotating rod 48 rotates clockwise, so that when limit plate 2 315 moves to the left and starts to squeeze the dust bag, the rope wheel 49, connecting plate 410 and hook 2 411 start to release the rope, and finally the hook 2 411 always follows the movement of the right end of the dust bag and maintains a certain limit. In this way, the right end of the dust bag can be always pulled by hook 2 411 to prevent the right side of the dust bag from falling off, and the pulling force on the right end of the dust bag when it shrinks is reduced, so as to avoid the bag located in the middle of limit plate 1 311 moving too much upward when the dust bag is squeezed.

[0058] The spray assembly 5 includes a water bag 1 51 fixedly connected to the right side wall of the inner surface of the box body 1, the left end of the water bag 1 51 is fixedly connected to the limit plate 2 315, the upper end of the water bag 1 51 is fixedly connected to a water pipe 1 52, the end of the water pipe 1 52 away from the water bag 1 51 is fixedly connected to two water boxes 313, and the two water boxes 313 are each provided with a spray head 53 on a side close to each other, the right end of the water bag 1 51 is fixedly connected to the water pipe 2 54, the end of the water pipe 2 54 away from the water bag 1 51 is fixedly connected to the water tank 55, and the left end of the water tank 55 is fixedly connected to the box body 1.

[0059] Furthermore, both water pipe 1 52 and water pipe 2 54 are provided with one-way valves. The one-way valve inside water pipe 1 52 can only discharge water outward but cannot absorb water, while the one-way valve inside water pipe 2 54 can only absorb water into water bag 1 51 but cannot discharge water.

[0060] The liquid stored in the water tank 55 contains a surfactant, SDS, which can reduce the surface tension of the liquid, making it easier for the water to wet the dust particles on the polyester fiber, preventing the dust particles from reaggregating, and improving the filtration uniformity.

[0061] Furthermore, when the limiting plate 2 315 is driven by the pushing block 34 to move toward the right to unfold the dust bag, the limiting plate 2 315 will squeeze the water bag 1 51, and the water in the water bag 1 51 will be transported to the water box 313 through the water pipe 1 52, and then sprayed from the spray head 53 to wet the dust in the dust bag, which can not only reduce the temperature but also suppress the flying of dust, and make it easier to collect and process the dust later. When the limiting plate 2 315 moves toward the left to drive the water bag 1 51 to open, the water bag 1 51 will absorb water from the water tank 55 through the water pipe 2 54 for replenishment.

[0062] Therefore, this solution first uses centrifugal force through the filter component 2 to perform preliminary filtration on the dust generated by the gas when the polyester fiber is dried. Then, through the cooperation of the dust collecting component 3 and the limit component 4, the dust falls into the dust collecting bag and is subjected to reciprocating squeezing to compact the dust, reducing the dust volume and improving the utilization of the dust collecting bag. In addition, intermittent spraying will be performed during the squeezing process, so that the dust can be fully moistened and quickly cooled, effectively suppressing the flying of subsequent dust treatment. As a whole, a process of dust filtration, compaction and anti-flying is formed, which not only reduces dust emissions but also improves the dust collection effect, reducing the harm of dust to the working environment and operators.

[0063] Embodiment 3: Based on Embodiments 1 and 2, this embodiment aims to achieve the effect of continuously wetting the filter plate 61 so as to maintain the dust adsorption capacity.

[0064] See Figure 1 、 Figure 2 、 Figure 11-12 The filter assembly 2 6 includes two filter plates 61 arranged on the upper part of the inner surface of the box body 1, a sponge 62 is arranged in the middle position of the two filter plates 61, the lower end of the lower filter plate 61 is fixedly connected to the water bag 2 63, the upper end of the right rotating shaft 23 is fixedly connected to the reciprocating rod 64, the outer surface of the reciprocating rod 64 is slidably connected to the extrusion block 65, the upper end of the mounting plate 27 is fixedly connected to the limiting column 66, the upper end of the limiting column 66 is fixedly connected to the lower end of the lower filter plate 61, the left side of the inner surface of the extrusion block 65 is slidably connected to the limiting column 66, and the upper end of the extrusion block 65 is in contact with the water bag 2 63.

[0065] Specifically, the limiting column 66 mentioned above can limit the extrusion block 65, so that the extrusion block 65 can move up and down stably and intermittently squeeze the water bag 2 63.

[0066] The sponge 62 is made of hydrophilic polyurethane sponge, which is resistant to hydrolysis and mildew.

[0067] Furthermore, the filter plate 61 is composed of a coated polyester filter cloth and a stainless steel wire mesh. The coated polyester filter cloth can accurately capture fine dust such as PM2.5, and the surface of the coated filter cloth is smooth and hydrophobic. Even when used with a water spray wetting device, the water film evenly covers the fibers but does not expand, thereby avoiding clogging of the holes. The stainless steel wire mesh provides strong support to prevent the filter cloth from deforming or tearing, thereby extending its service life. The coated filter cloth is resistant to aging and is not easily damaged in a long-term humid environment. The filter plate 61 can be installed and disassembled, and both are very mature existing technologies, so the disassembly and assembly methods are not elaborated in detail in this case.

[0068] The front end of water bag 2 63 is fixedly connected to water pipe 3 67 , which extends into the interior of sponge 62 and is evenly distributed. A number of circular holes are provided on the outer surface of water pipe 3 67 . The right end of water bag 2 63 is fixedly connected to water pipe 4 68 , and the lower end of water pipe 4 68 is fixedly connected to the water tank 55 .

[0069] The reciprocating rod 64 is a ball screw mechanism in the prior art;

[0070] Furthermore, when the rotating shaft 1 23 rotates, it will drive the reciprocating rod 64 to rotate together, causing the squeezing block 65 to slide up and down. When the squeezing block 65 rises to the position of the water bag 2 63, it will squeeze the water bag 2 63, causing the water inside the water bag 2 63 to spray out from the hole on the water pipe 3 67, uniformly moistening the sponge 62, thereby ensuring that the two filter plates 61 are always in a moist state, and absorbing the remaining fine particles of dust in the gas.

[0071] Therefore, in this solution, by cooperating with filter component 1 2 and filter component 2 6, the extrusion block 65 realizes the reciprocating intermittent squeezing of water bag 2 63 under the drive of the reciprocating rod 64. This method enables the sponge 62 to always remain moist, providing a continuous wetting effect for the two filter plates 61, maintaining the dust adsorption capacity of the filter plates 61, and improving the overall filtering effect.

[0072] It should be noted that the specific installation method of the fan and the motor 22, the circuit connection method, and the control method used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
