Description

Technical Field

[0001] This invention relates to the field of textile processing technology, and more specifically, to a high-efficiency dust collection and recovery device for textile processing. Background Technology

[0002] In the textile production process, each step generates a large amount of fly ash, mainly composed of short fibers and dust. Currently, textile companies generally use centralized dust collection systems, which draw in fly ash from various dust-generating points through a pipeline network and collect it through main filters such as bag filters. The collected fly ash is a complex mixture containing reusable long fibers, non-spinnable short fibers, and sizing dust. In existing technologies, this mixed fly ash is usually packaged and sold as low-grade recycled fiber raw materials or disposed of in landfills, failing to effectively tap its economic value.

[0003] However, the existing processing methods described above have significant drawbacks. Due to the lack of effective sorting of the mixed fly filaments, high-value reusable long fibers are completely mixed with low-value short fibers and dust. This results in a severe devaluation of the high-value reusable fiber resources, preventing them from being fully utilized. Existing recycling devices typically use vibration screening to initially remove impurities from the mixed fly filaments, but due to factors such as static electricity and workshop humidity, the complex mixture of long fibers, non-spinning short fibers, and sizing dust in the fly filaments easily entangles and clumps, making effective sorting of the mixed fly filaments difficult and severely impacting the sorting quality. Summary of the Invention

[0004] The present invention provides a high-efficiency dust collection and recycling device for textile processing. The problem to be solved is that existing recycling devices generally use vibration screening to perform preliminary impurity removal on mixed fly filaments. Due to factors such as static electricity and workshop humidity, the complex mixture of long fibers, non-spinning short fibers and sizing dust in the fly filaments is prone to entanglement and clumping, making it difficult to effectively sort the mixed fly filaments, thus seriously affecting the sorting quality.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a high-efficiency dust collection and filtration device for textile processing, comprising: The sorting box is equipped with a feeding pipe and a dust extraction hood.

[0007] In a preferred embodiment, a monitoring mechanism is provided on the sorting box. The monitoring mechanism includes several rotating rods rotatably disposed on one side of the sorting box. A stop bar is provided at one end of the rotating rod inside the sorting box, which is horizontally positioned above the elastic rope. The stop bar is perpendicular to the corresponding elastic rope. The end of the rotating rod away from the stop bar extends out of the outer side of the sorting box and is provided with a striking ball. Several touch switches and warning lights are provided on the outer side of the sorting box. The touch switches are located below the corresponding striking balls and are used to control the activation and deactivation of the warning lights.

[0008] In a preferred embodiment, the sorting box has a plurality of rectangular holes, and the rotating rod passes through the corresponding rectangular holes. An isolation plate is fixedly installed on the rotating rod, and the isolation plate is adapted to the rectangular holes.

[0009] In a preferred embodiment, the vibrating screen is provided with two speed reduction plates, which are staggered vertically and inclined, and are located between the vibrating screen and the dust extraction hood.

[0010] In a preferred embodiment, both the feeding pipe and the dust extraction hood are located above the vibrating screen.

[0012] In a preferred embodiment, the air blowing pipe group is externally connected to a hot air conveying device, and the air force of several air blowing pipe groups decreases along the output direction of the vibrating screen.

[0013] In a preferred embodiment, a dust extraction device is connected to the outside of the dust extraction hood, and a feeding device is connected to the outside of the feeding pipe.

[0014] In a preferred embodiment, the stop bar is located at the center above the corresponding elastic rope, and both the vibrating screen and the support box are externally connected to a grounding wire.

[0019] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0020] In textile workshops, vacuum cleaners and other equipment are typically used to collect fly ash. During this process, moisture from the air mixes in with the fly ash. As the fly ash mixture is squeezed, it becomes entangled and clumps together, easily trapping sizing powder particles, dust, short fibers, and other debris, making it difficult to separate the different materials.

[0021] Example 1 Refer to the instruction manual appendix Figure 1 and Figure 10 This embodiment proposes a high-efficiency dust collection and recovery device for textile processing. It addresses the problem in existing technologies where, during the initial impurity removal of mixed fly ash using vibration screening, factors such as static electricity and workshop humidity cause the complex mixture of long fibers, non-spinnable short fibers, and sizing dust in the fly ash to easily entangle and agglomerate, making effective sorting of the mixed fly ash difficult and severely impacting sorting quality. The device includes: The sorting box 1 is equipped with a feeding pipe 2 and a dust extraction hood 3. The sorting box 1 is equipped with a screening mechanism 4. The screening mechanism 4 includes a support box 41 with the output end tilted downward. A vibrating screen 44 is movably mounted on the support box 41. Several drive components 47 are evenly arranged at the bottom of the vibrating screen 44. Several through hole areas are evenly arranged on the vibrating screen 44. Several air blowing pipe groups 42 are mounted on the support box 41. The output ends of the air blowing pipe groups 42 are respectively facing the corresponding through hole areas. It should be noted that the drive component 47 is a vibrating motor, which can also be replaced by a cam mechanism. This is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment. When the fly waste mixture enters the sorting box 1, it will fall onto the input end of the vibrating screen 44 under the guidance of the feeding pipe 2. Since both the support box 41 and the vibrating screen 44 are inclined, the fly waste mixture will gradually move under the continuous vibration of the composite vibrating screen 44. The hole size in the through hole area is smaller than the minimum size of the long fiber. At the same time, the uniformly distributed through holes can achieve the effect of equalizing the airflow.

[0022] Several spring rods 45 are evenly arranged on both sides of the vibrating screen 44. The spring rods 45 are movably connected to the support box 41. A dispersing mechanism 5 is provided on the vibrating screen 44. The dispersing mechanism 5 includes several elastic ropes 54 evenly arranged along the length of the vibrating screen 44. Both ends of the elastic ropes 54 pass through the vibrating screen 44 and extend to the outside of the sorting box 1. The elastic ropes 54 are used to break up the fly ash clumps.

[0023] It should be noted that the elastic cord 54 can be made of silicone or polyurethane material, with a diameter in the range of 2-10mm, and multiple elastic cords 54 are arranged horizontally at equal intervals.

[0024] In this embodiment, the specific implementation scenario is as follows: First, the drive assembly 47 is activated, thereby driving the vibrating screen 44 to generate continuous vibration. At the same time, hot airflow is continuously delivered to the through-hole area on the vibrating screen 44 through the air blowing pipe assembly 42, and the flow rate is controlled so that the airflow can only blow the pulp powder, dust particles, and fine short fibers into the suction range of the dust extraction hood 3, while the long fiber monomers will only initially float to the area where the highly elastic rope 54 swings and hits. At this time, the elastic rope 54 is continuously oscillating under the influence of the vibrating screen 44, and when it winds... When the clumped fly mixture passes through the area of ​​the elastic cord 54, it will be continuously struck by the elastic cord 54. After being dried by the hot air in the front section, the fly mixture can be more easily dispersed. After passing through the dispersion area of ​​the elastic cord 54, the particles of pulp powder, dust and fine short fibers will be dispersed from the high-value long fibers. At this time, the air blowing pipe assembly 42 will blow the particles of pulp powder, dust and fine short fibers into the suction capture range of the dust hood 3, while the high-value long fibers will be discharged from the discharge trough 2 49 and collected. It should also be noted that the elastic rope 54 is generally set in the middle section of the vibrating screen 44, while the two ends of the vibrating screen 44 are not equipped with elastic rope 54. This allows the mixed fly waste to undergo the screening process of "drying, dispersing, and air-blowing separation" on the vibrating screen 44 in sequence. In addition, controlling the setting range of the elastic rope 54 can also prevent the original long fibers from being broken due to excessive impact, thereby reducing the good product recovery rate.

[0025] Several sets of supports 51 are provided on the outside of the sorting box 1. Each set of supports 51 includes two symmetrically arranged support units 51. A rope storage wheel 52 and a support wheel 53 are rotatably arranged on the support unit 51. The two ends of the elastic rope 54 pass around the corresponding support wheel 53 and are wound around the rope storage wheel 52.

[0026] It should be noted that, in the initial state, one end of the elastic rope 54 is fixed to one of the rope storage wheels 52 in a set of rope storage wheels 52, while most of the reserved redundant elastic rope 54 is wound around the corresponding other rope storage wheel 52. The rotation between the rope storage wheel 52 and the bracket 51 is preset with a certain damping value, or it can be limited by a buckle. This is a mature technology well known to those skilled in the art, and will not be described in detail in this embodiment. The elastic rope 54 will reserve sufficient length on the vibrating screen 44 according to the preset tension.

[0027] Example 2 Based on Embodiment 1, this embodiment proposes a monitoring mechanism 6 to solve the problem in the prior art that the elastic rope 54 will wear out, loosen and get dirty when working in a dusty and high-vibration environment for a long time, resulting in a decrease in the dispersing efficiency. In addition, since the elastic rope 54 is installed in the middle position inside the sorting box 1, replacement and cleaning are relatively cumbersome.

[0028] The sorting box 1 is equipped with a monitoring mechanism 6, which includes several rotating rods 61 rotatably mounted on one side of the sorting box 1. One end of the rotating rod 61 inside the sorting box 1 is equipped with a stop bar 62 horizontally positioned above the elastic rope 54. The stop bar 62 is perpendicular to the corresponding elastic rope 54. The end of the rotating rod 61 away from the stop bar 62 extends out of the outer side of the sorting box 1 and is equipped with a striking ball 63. Several touch switches 65 and warning lights 66 are provided on the outer side of the sorting box 1. The touch switches 65 are located below the corresponding striking balls 63 and are used to control the start and stop of the warning lights 66.

[0029] It should be noted that, initially, the stop lever 62 is located outside the maximum swing range of the elastic cord 54. That is, when the elastic cord 54 is not slack, the swinging elastic cord 54 cannot strike the stop lever 62. Furthermore, the weight of the rotating rod 61 and the stop lever 62 also prevents airflow from moving. Therefore, when the elastic cord 54 does not strike the stop lever 62, the rotating rod 61 is essentially stationary, preventing the striking ball 63 from rotating and contacting the trigger switch 65. When the elastic cord 54 becomes slack, its swing range automatically increases. As the swing range increases, the elastic cord 54 gradually becomes able to strike the stop lever 62, and with increasing striking force... Ultimately, the impact of the elastic rope 54 on the stop lever 62 causes the rotating rod 61 to rotate, thereby causing the striking ball 63 to touch the trigger switch 65, which in turn causes the warning light 66 to light up and alarm. At the same time, the striking ball 63 and the trigger switch 65 can be made of materials that produce a loud striking sound, so as to achieve a dual warning of light and color, making it easy for staff to notice in time. Then, by rotating the two rope storage wheels 52, the redundant section of the elastic rope 54 that has not shown material fatigue can be replaced without disassembling the equipment casing. At the same time, individual elastic ropes 54 can be replaced. During the replacement process, any flying debris that may be entangled on the elastic rope 54 will also be scraped off by the edge of the vibrating screen 44.

[0030] The sorting box 1 has several rectangular holes, and the rotating rod 61 passes through the corresponding rectangular holes. An isolation plate 64 is fixedly installed on the rotating rod 61, and the isolation plate 64 is adapted to the rectangular holes.

[0031] It should be noted that the insulating plate 64 can be made of a flexible material, such as rubber or silicone, to ensure the sealing effect of the sorting box 1 and prevent the overflow of fly shavings mixture.

[0032] Example 3 Based on Embodiment 2, this embodiment proposes a speed deceleration plate 48 to solve the problem in the prior art that long fibers may accidentally fly into the capture range of the dust extraction hood 3 due to factors such as the upward swing of the elastic rope 54 and turbulent airflow, resulting in the waste of high-value long fibers.

[0033] Two speed reduction plates 48 are provided on the vibrating screen 44. The two speed reduction plates 48 are staggered and inclined. Both speed reduction plates 48 are located between the vibrating screen 44 and the dust extraction hood 3.

[0034] It should be noted that long fibers are heavier and larger than particles of sizing powder, dust, and fine short fibers, and therefore have greater inertia during flight. When long fibers hit the deceleration plate 48, they will experience a greater rebound force, making them more likely to fall back down. Meanwhile, particles of sizing powder, dust, and fine short fibers will fly into the capture range of the dust extraction hood 3 through the gap between the two intersecting deceleration plates 48. Furthermore, the suction power of the dust hood 3 is preset to be lower than the weight of long fibers, but greater than the weight of powder, dust particles, and fine short fibers. Even if a small number of long fibers accidentally fly above the deceleration plate 48, the airflow area will suddenly increase after passing through the gap between the two deceleration plates 48, thus causing the airflow to slow down. Therefore, the relatively heavier long fibers will slow down and fall, thereby preventing the long fibers from being incorrectly sorted in all aspects.

[0035] The feeding pipe 2 and the dust extraction hood 3 are both located above the vibrating screen 44. The feeding pipe 2 is located on one side of the input end of the vibrating screen 44. The output end of the vibrating screen 44 is provided with a second feeding trough 49, and the output end of the support box 41 is provided with a first feeding trough 43. The first feeding trough 43 is located below the second feeding trough 49.

[0036] It should be noted that during the sorting process, a small amount of pulp powder, dust particles, and fine short fibers may fall through the through holes into the support box 41. Therefore, these pulp powder, dust particles, and fine short fibers will be discharged from the feed chute 43.

[0037] The input end of the vibrating screen 44 is equipped with a baffle 46, which is compatible with the feed pipe 2. Triangular plates are provided on both sides of the top of the vibrating screen 44, which are used to guide the fly waste.

[0038] It should be noted that baffle 46 is used to guide the fly ash mixture.

[0039] The air blowing pipe assembly 42 is externally connected to a hot air conveying device, and the air force of several air blowing pipe assemblies 42 decreases along the output direction of the vibrating screen 44.

[0040] It should be noted that as the fly ash mixture becomes more and more dispersed on the vibrating screen 44, the air force generated by the air blowing pipe assembly 42 will also become smaller and smaller, in order to avoid a large number of long fibers being blown to the top of the speed reduction plate 48.

[0041] The dust extraction hood 3 is connected to a dust extraction device, and the feeding pipe 2 is connected to a feeding device.

[0042] It should be noted that, The stop bar 62 is located in the center above the corresponding elastic rope 54, and both the vibrating screen 44 and the support box 41 are connected to an external grounding wire.

[0043] It should be noted that the fly ash mixture will be destaticated as soon as it enters the vibrating screen 44, so as to reduce the adhesion between them.

[0044] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention.
