Description

Technical Field

[0001] This invention relates to the technical field of chemical fiber machinery, specifically to a device for opening and transporting fibers and intelligently adjusting water spray, which is particularly suitable for the post-processing of viscose or Lyocell short fibers. Background Technology

[0002] In the chemical fiber industry, post-processing of viscose or Lyocell staple fibers is a crucial step before the finished fiber product. The fiber feeding tube is one of the most important units in the post-processing equipment, located between the cutter and the fiber feeding trough. Its main function is to smoothly transport the cut viscose or Lyocell staple fibers to the feeding trough, and during this process, break up clumps of fiber (commonly known as "ribbonfish chunks") and prevent the fibers from tangling (i.e., forming "radish shreds"). This improves the uniformity of fiber spreading and the washing effect in subsequent processes, reduces the consumption of circulating water and steam in subsequent processes, and ultimately improves the quality of the finished fiber product. The amount of "ribbonfish chunks" and "radish shreds" in the finished fiber is a key indicator of the effectiveness of the fiber feeding tube.

[0003] Traditional fiber opening tubes are mostly straight round or square tubes, primarily serving a conveying function. Customers generally don't have high requirements for the opened fibers, and they don't pay much attention to the quality of the finished fiber or energy consumption. However, with continuous technological advancements and increased societal awareness of energy conservation and environmental protection, customers are placing greater emphasis on the opening function of fiber opening tubes, leading to significant improvements in their technical level. But as customers relentlessly pursue large production capacities, the number of cutting machines is constantly increasing, and conveying distances are growing longer, while the material inlet and outlet drop has not increased accordingly. This situation is particularly prominent in large-capacity Lyocell fiber post-processing production lines with an annual output of 50,000 tons or more, resulting in various problems such as poor fiber conveying, excessive water usage for flushing, poor fiber opening effects, and excessive fiber strands or braids, for which no satisfactory solution has yet been found. This not only leads to high energy consumption but also results in frequent complaints about the finished product failing to meet downstream users' quality requirements for high-grade fibers. Therefore, there is an urgent need to design a device for opening and conveying fibers with intelligent water spray adjustment to solve these technical problems. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the existing technology by providing a device for opening and transporting fibers while intelligently regulating water spray. This invention enhances the opening effect and efficiency of fibers within the fiber-feathering tube, provides kinetic energy for smooth fiber transport, and intelligently regulates and effectively reduces the water consumption of the entire fiber-feathering tube. It offers advantages such as high efficiency and intelligence, excellent opening effect, high-quality finished fiber, smooth fiber transport, low rinsing water consumption, low operating energy consumption, and cost savings.

[0005] The objective of this invention can be achieved through the following technical measures:

[0006] This invention discloses a device for opening and transporting fibers with intelligent water spray adjustment. The device comprises a rectangular weir-shaped pipe with a stepped weir-like structure on the bottom surface and a top surface composed of segmented, pull-out movable covers. Material inlet flanges and material outlet flanges are welded to both ends of the rectangular weir-shaped pipe. Several high-speed water spray pipes are evenly distributed along the length of the upper part of the rectangular weir-shaped pipe, traversing the inner cavity. A high-pressure water supply system is provided to the high-speed water spray pipes. The rectangular weir-shaped pipe is connected to two sections of fiber-feeding pipes via the material inlet and outlet flanges at both ends. Its main function is to smoothly transport cut viscose or Lyocell short fibers to the fiber feeding trough, and to disperse clumps of fiber during transport, preventing fiber entanglement and improving subsequent processing efficiency. The rectangular weir-type tube features a stepped weir structure on its inner bottom surface. Compared to traditional straight or square tubes, this structure increases the contact area between the fiber and the high-speed water flow, creating a vertical drop in the fiber's height. This makes the fiber easier to disperse and open with the high-speed water flow, enhancing the opening effect and efficiency. It boasts advantages such as high opening efficiency, good opening effect, and high-quality finished fiber. The top surface is constructed from segmented, pull-out movable covers, facilitating observation of fiber flow and opening within the rectangular weir-type tube. A high-speed water spray pipe and water supply system are installed to ensure uniform fiber distribution and reduce subsequent water and steam consumption. The striking method loosens the fibers and provides kinetic energy for the smooth transport of fibers in the fiber-feeding tube, ensuring the smooth delivery of fibers to the fiber-feeding trough. The stepped weir structure refers to a rectangular weir tube whose inner cavity bottom surface is formed by molding several identical and sequentially connected stepped structures using steel plates. (The stepped weir structure increases the contact area between the fibers and the high-speed water flow, and creates a vertical undulation in the fiber's trajectory, making it easier for the fibers to be blown and pulled apart by the high-speed water flow, thus enhancing the fiber-loosening effect and improving the loosening efficiency within the fiber-feeding tube. It boasts advantages such as high loosening efficiency, good loosening effect, and high-quality finished fibers.) Furthermore, the structure follows a continuous stepped pattern with a gentle uphill slope and a steep downhill slope along the material's direction of movement (ensuring the fibers are smoothly transported to the fiber-feeding trough during operation). There is a certain vertical undulation (i.e., the length of the upslope of each step is greater than the length of the downslope), the horizontal angle between the upslope and the material running direction is 15-20 degrees, and the horizontal angle between the downslope and the material running direction is -30 degrees (to ensure that the fiber is first lifted by the long slope and then falls along a short slope during forward conveying, which makes it easier for the fiber to be blown and pulled apart by the high-speed water flow, thereby enhancing the opening effect of the fiber in the fiber-loosening tube and improving the opening efficiency). The end of the upslope in the stepped weir structure is near the material inlet flange section; the water supply system is composed of several water spray branches connected in parallel by a series of high-speed water spray pipes, loose flange assemblies, and automatic regulating valves, and then connected to the main water pipe, centrifugal pump and water tank.A row of spray holes is formed along the length of the surface of the high-speed water jet pipe (for spraying high-speed water into the inner cavity of the rectangular weir-type pipe, which disperses the fibers in the rectangular weir-type pipe by impacting them, thus loosening the fibers in the fiber-forming tubes). The axis of the spray holes extends along the radial direction of the water jet pipe. The arrangement angle of the spray holes relative to the cross section of the high-speed water jet pipe can be steplessly adjusted. The spray angle can be adjusted by rotating the loose flange assembly (the arrangement angle of the spray holes on each branch of the high-speed water jet pipe can be flexibly adjusted as needed—that is, it can be easily achieved by rotating the loose flange assembly). A flow sensor is arranged at the material outlet flange section (the flow sensor can monitor the water flow at the material outlet end of the rectangular weir-type pipe in real time). The system monitors the water flow rate and transmits the generated water flow signal back to the centralized control system in a timely manner. The flow sensor and the automatic regulating valves in each spray branch are connected to the centralized control system via electrical signals. Based on the water flow feedback signal and the established relationship between the spray flow rate, angle, and delivery flow, the centralized control system sends a control signal to the automatic regulating valve on the spray branch corresponding to the desired spray angle. This opens and adjusts the spray flow rate on the corresponding spray branch, thereby achieving intelligent adjustment of the spray flow rate and angle. This intelligently adjusts and effectively reduces the water consumption of the entire spray pipe, offering advantages such as low rinsing water consumption, low operating energy consumption, and cost savings.

[0007] In this invention, both the material inlet flange section and the material outlet flange section are constructed by sequentially welding a flange, a cylindrical cavity section, and a transition section (the flange and bolts enable quick connection between this invention and the cutting machine and the fiber feeding trough). The small end of the transition section has a circular cross-section, which is the same as the cross-section of the cylindrical cavity section (ensuring that the small end of the transition section can be smoothly butt-welded to the cylindrical cavity section). The large end of the transition section has a rectangular cross-section, which is welded to the end of the rectangular weir-type pipe (ensuring that the large end of the transition section can be smoothly butt-welded to the cylindrical cavity section).

[0008] The design principle of this invention is as follows:

[0009] This invention improves the main collection tube of the fiber feeding tube, which connects the cutting machine and the fiber feeding trough and is used to transport the cut viscose or Lyocell short fibers. Specifically, it changes the traditional straight round or square tube structure to a rectangular weir-shaped tube with a rectangular outer surface, a stepped weir-like structure on the bottom surface of the inner cavity, and a top surface composed of segmented, pull-out movable covers. Simultaneously, this invention also includes several high-speed water jet pipes evenly distributed along the length of the upper part of the rectangular weir-shaped tube, providing a high-pressure water supply system for the high-speed water jet pipes. In this way, the water supply system, in conjunction with the high-speed water jet pipes, can both loosen the fibers through water jet impact and provide kinetic energy for the smooth transport of fibers through the fiber feeding tube, ensuring the smooth delivery of fibers to the fiber feeding trough. Compared to traditional straight or square tubes used for fiber shedding, the rectangular weir-type tube in this invention features a stepped weir structure on its inner bottom surface. This increases the contact area between the fibers and the high-speed water flow, and creates a vertical drop in the fibers during operation. This makes the fibers easier to disperse and pull apart by the high-speed water flow, thereby enhancing the opening effect and efficiency of the fibers within the tube. It boasts advantages such as high opening efficiency, excellent opening effect, and high-quality finished fibers. The top surface structure, composed of segmented, pull-out movable covers, facilitates observation of the fiber flow and opening within the rectangular weir-type tube. Furthermore, this invention includes a flow sensor at the material outlet flange section, and both the flow sensor and the automatic regulating valve are connected to the centralized control system via electrical signals. In this way, the flow sensor transmits the real-time water flow signal to the centralized control system. Based on the water flow feedback signal and the established relationship between the spray flow rate and angle and the delivery flow rate, the centralized control system sends a control signal to the automatic regulating valve on the spray branch corresponding to the required spray angle. This opens and adjusts the spray flow rate on the corresponding spray branch, thereby achieving intelligent adjustment of the spray flow rate and angle. This intelligently adjusts and effectively reduces the water consumption of the entire rinsing pipe, offering advantages such as low rinsing water consumption, low operating energy consumption, and cost savings. The flexible adjustment of the spray hole arrangement angle of the high-speed spray pipe on each spray branch can be easily achieved by rotating the loose flange assembly.

[0010] The beneficial technical effects of the present invention are as follows:

[0011] This invention can enhance the opening effect and efficiency of fibers in the fiber sheath, provide kinetic energy for smooth fiber transport in the fiber sheath, and intelligently adjust and effectively reduce the water consumption of the entire fiber sheath. It has the advantages of high efficiency and intelligence, good opening effect, high fiber quality, smooth fiber transport, low rinsing water consumption, low operating energy consumption, and cost saving.

Detailed Implementation

[0022] The present invention will be further described below with reference to the accompanying drawings and simulation experiments:

[0023] like Figures 1-9As shown, the present invention provides a device for opening and transporting fibers with intelligent water spray adjustment. This device includes a rectangular weir-type pipe 1 with a rectangular outer surface, a stepped weir-type structure 1-1 on the bottom surface of the inner cavity, and a rectangular weir-type pipe 1 formed by segmented pull-out movable covers 1-2 on the top surface. Material inlet flange section 2 and material outlet flange section 3 are welded to both ends of the rectangular weir-type pipe 1. Several high-speed water spray pipes 4 are evenly distributed along the length of the upper part of the rectangular weir-type pipe 1, traversing the inner cavity. A water spray supply system A provides high-pressure water to the high-speed water spray pipes 4. (The rectangular weir-type pipe is connected between two sections of fiber-feeding pipes via the material inlet flange section and the material outlet flange section at both ends. It is mainly used to smoothly transport cut viscose or Lyocell short fibers to the fiber feeding trough.) During the conveying process, the bulky fibers are dispersed and prevented from tangling, thereby improving the uniformity of fiber spreading and rinsing effects in subsequent processes, and reducing the consumption of circulating water and steam in subsequent processes. The inner bottom surface of the rectangular weir-type pipe is designed with a stepped weir structure. Compared with traditional straight round or square fiber-laying pipes, the stepped weir structure can increase the contact area between the fibers and the high-speed water flow, and allow the fibers to have a vertical undulation during operation. This makes it easier for the fibers to be blown and pulled apart by the high-speed water flow, thereby enhancing the opening effect of the fibers in the fiber-laying pipe and improving the opening efficiency. It has the advantages of high opening efficiency, good opening effect, and high fiber quality. The top surface is composed of segmented pull-out movable covers, which facilitates the observation of the rectangular weir. The flow and opening of fibers within the weir-type pipe; a high-speed water jet pipe and water supply system are installed, which can both open the fibers by water jet impact and provide kinetic energy for the smooth transport of fibers in the fiber-feeding tube, ensuring the smooth delivery of fibers to the fiber-feeding trough; the stepped weir structure 1-1 refers to the bottom surface of the inner cavity of the rectangular weir-type pipe 1 being a series of continuous stepped structures of the same size and connected sequentially, formed by molding steel plates (the stepped weir structure can increase the contact area between the fibers and the high-speed water flow, and allow the fibers to have a vertical undulation difference during operation, which makes the fibers easier to be blown and pulled apart by the high-speed water flow, thereby enhancing the opening effect of the fibers in the fiber-feeding tube and improving the opening efficiency, with high opening efficiency and good opening effect). The advantages of high-quality finished fiber products are that the structure is a continuous stepped structure with a gentle uphill slope and a steep downhill slope along the direction of material movement (ensuring that the fiber has a certain vertical drop during operation). That is, the length of the uphill surface of each step is greater than the length of the downhill surface. The horizontal angle between the uphill surface and the direction of material movement is 15 to 20 degrees, and the horizontal angle between the downhill surface and the direction of material movement is -30 degrees (ensuring that the fiber is first lifted by the long slope and then falls along a short slope during forward conveying. This makes it easier for the fiber to be blown and pulled apart by the high-speed water flow, thereby enhancing the opening effect of the fiber in the fiber sheath and improving the opening efficiency). The end of the uphill surface in the stepped weir structure 1-1 is near the end of the material inlet flange section 2.The water supply system A consists of several water spray branches connected in parallel, each composed of a high-speed water spray pipe 4, a loose flange assembly 5, and an automatic regulating valve 6, which are then connected to the main water pipe 7, a centrifugal pump 8, and a water tank 9. A row of water spray holes is formed along the length of the surface of the high-speed water spray pipe 4 (used to spray high-speed water into the inner cavity of the rectangular weir-type pipe 1, thereby breaking up the fibers in the rectangular weir-type pipe 1 and loosening the fibers within the fibers of the capillary tube). The axis of the water spray holes extends radially along the water spray pipe. The arrangement angle of the water spray holes relative to the cross-section of the high-speed water spray pipe 4 can be infinitely adjusted. The water spray angle can be adjusted by rotating the loose flange assembly 5 (the arrangement angle of the water spray holes on each water spray branch can be flexibly adjusted as needed—that is, easily achieved by rotating the loose flange assembly). A water spray hole is arranged at the material outlet flange section. A flow sensor 10 is included (which monitors the water flow at the material outlet of the rectangular weir pipe in real time and promptly feeds back the generated water flow signal to the centralized control system). The flow sensor 10 and the automatic regulating valves 6 in each spray branch are connected to the centralized control system via electrical signals. (The flow sensor promptly feeds back the monitored water flow signal to the centralized control system. Based on the water flow feedback signal and the established relationship between the spray flow rate, angle, and delivery flow, the centralized control system sends a control signal to the automatic regulating valve on the spray branch corresponding to the desired spray angle, thus opening and adjusting the spray flow rate on that corresponding spray branch. This achieves intelligent adjustment of the spray flow rate and angle, effectively reducing the water consumption of the entire corrugated pipe, resulting in advantages such as low flushing water consumption, low operating energy consumption, and cost savings.)

[0024] In this invention, the material inlet flange section 2 and the material outlet flange section 3 are both welded together by a flange, a cylindrical cavity section and a transition section in sequence (the flange and bolts enable the invention to be quickly connected to the cutting machine and the fiber feeding trough). The small end of the transition section has a circular cross-section, which is the same as the cross-section of the cylindrical cavity section (ensuring that the small end of the transition section can be smoothly butt-welded to the cylindrical cavity section). The large end of the transition section has a rectangular cross-section, which is welded to the end of the rectangular weir pipe 1 (ensuring that the large end of the transition section can be smoothly butt-welded to the cylindrical cavity section).

[0025] The specific steps for using this invention are as follows:

[0026] A. Install water spray branch lines: Install several water spray branch lines, which are composed of high-speed water spray pipes 4, loose flange assembly 5, and automatic regulating valve 6 connected in series, one by one to the corresponding positions on the upper part of the rectangular weir pipe 1, and adjust the angle of the water spray hole in each high-speed water spray pipe 4 to the required angle by rotating the loose flange assembly 5.

[0027] B. Install rectangular weir pipe: Install rectangular weir pipe 1 between the two sections of capillary tube collection pipe section - that is, align the flange in the material inlet flange section 2 with the corresponding flange at the outlet of the capillary tube collection pipe section at the cutter end and tighten it with bolts, and align the flange in the material outlet flange section 3 with the corresponding flange at the inlet of the capillary tube collection pipe section at the fiber feeding trough end and tighten it with bolts.

[0028] C. Form a water supply system: Connect the inlet ends of all water spray branches to the main water pipe 7 in parallel; connect the centrifugal pump 8 in series at the inlet end of the main water pipe 7 and then connect it to the water tank 9.

[0029] D. Connecting the centralized control system: After installing the flow sensor 10 at the material outlet flange section 3, connect the flow sensor 10 and the automatic regulating valve 6 in each water spray branch to the centralized control system via electrical signals.

[0030] E. Opening and Transporting Fibers: Centrifugal pump 8 is turned on, and water in pool 9 is pumped into main water pipe 7 and distributed to various spray branches; the water flowing into each spray branch will be ejected at high speed from a row of spray holes on the surface of high-speed spray pipe 4 to form a high-pressure water flow; on the one hand, the high-pressure water flow ejected from the spray holes can provide kinetic energy for the smooth transport of fibers in the capillary tube, ensuring that the fibers are smoothly transported to the fiber feeding groove; on the other hand, the high-pressure water flow ejected from the spray holes can open the fibers in the capillary tube—that is, the fibers in the inner cavity of the rectangular weir-type pipe 1 are dispersed by the impact of the high-speed water flow; in addition, the present invention has improved the main collection pipe of the capillary tube—that is, it has been improved from the traditional straight round pipe or straight square pipe structure to a rectangular outer surface, a stepped weir-type structure 1-1 on the bottom surface of the inner cavity, and a top surface composed of a... The rectangular weir-type pipe 1, which is formed by the combination of two movable shells 1-2, is different from traditional straight round or square tubes. In this invention, the bottom surface of the rectangular weir-type pipe 1 is designed as a stepped weir structure 1-1, which can increase the contact area between the fiber and the high-speed water flow and allow the fiber to have a vertical drop during operation. This makes it easier for the fiber to be blown and pulled apart by the high-speed water flow, thereby enhancing the opening effect and improving the opening efficiency of the fiber in the tube. It has the advantages of high opening efficiency, good opening effect and high fiber quality. Moreover, the top surface structure formed by the combination of two movable shells 1-2 makes it easy to observe the flow and opening of the fiber in the rectangular weir-type pipe 1.

[0031] F. Intelligent Spray Adjustment: The flow sensor 10 promptly transmits the real-time monitored water flow signal to the centralized control system. Based on the water flow feedback signal and the established relationship between the spray flow and angle and the delivery flow, the centralized control system sends a control signal to the automatic regulating valve 6 on the spray branch corresponding to the required spray angle. This opens and adjusts the spray flow on the corresponding spray branch, thereby achieving intelligent adjustment of the spray flow and angle. This intelligently adjusts and effectively reduces the water consumption of the entire rinsing pipe, offering advantages such as low rinsing water consumption, low operating energy consumption, and cost savings. The flexible adjustment of the spray hole arrangement angle of the high-speed spray pipe 4 on each spray branch can be easily achieved by rotating the loose flange assembly 5.

[0032] The fiber particle dynamics equation is expressed as:

[0033] (1)

[0034] Where: m i Represents particles i The quality; r i =x i (t)i+y i (t)j+z i (t)k Represents particles i Its position in the flow field; F b Represents particles i The bending restoring force it is subjected to; F D Represents particles i The resistance encountered in the flow field.

[0035] To further verify the effect of the stepped weir structure 1-1 designed in the rectangular weir pipe 1 of this invention and the addition of high-pressure water to the stepped weir structure 1-1 on the fiber opening effect, the following sets of simulation experiments were conducted, and the fiber opening state pictures were taken during these sets of experiments to show the simulation results.

[0036] Simulation Experiment 1

[0037] Experimental conditions: Fibers were transported in a rectangular tube using a water flow of 1 m / s. Simulation results are as follows. Figure 4 , Figure 5 As shown.

[0038] Simulation Experiment 2

[0039] Experimental conditions: Fibers were transported in the rectangular weir-type pipe of this invention using a water flow of 1 m / s. Simulation results are as follows. Figure 6 , Figure 7 As shown.

[0040] Simulation Experiment 3

[0041] Experimental conditions: Fibers were transported in the rectangular weir-type pipe of this invention using a water flow of 1 m / s, while the water pressure from a row of spray holes on the surface of the high-speed water jet pipe 4 above was set to 200,000 Pa; simulation results are as follows. Figure 8 , Figure 9 As shown.

[0042] By comparing the above Figure 4 , Figure 5 The fiber state displayed in the square tube and Figure 6 , Figure 7 The fiber state shown in the rectangular weir tube indicates that the fibers in the rectangular weir tube are in a good open state, while the fibers in the square tube tend to aggregate together.

[0043] By comparing the above Figure 6 , Figure 7 The displayed fiber state in the rectangular weir-type pipe without adding high-pressure water jets and Figure 8 , Figure 9 The fiber state after adding high-pressure water spray in the rectangular weir pipe shows that the fibers are stretched longer and the opening effect is relatively better.

[0044] Therefore, based on the simulation results above, the rectangular weir-type pipe in this invention, compared to the traditional square pipe structure, increases the contact area between the fiber and the high-speed water flow by adding a stepped weir structure 1-1 to the bottom surface of the inner cavity. Furthermore, it creates a vertical undulation in the fiber's height during operation, making it easier for the fiber to be dispersed and pulled apart by the high-speed water flow. This enhances the opening effect and efficiency of the fiber within the capillary tube, resulting in high opening efficiency, good opening effect, and high-quality finished fiber. Simultaneously, the invention incorporates a high-speed water jet pipe 4 with a pressure of 200,000 Pa. The high-pressure water jet from the nozzle further enhances the opening effect on the fiber within the capillary tube.
