Description

Technical Field

[0001] The utility model relates to the technical field of flash spinning, in particular to a steering device and flash spinning equipment. Background Art

[0002] High-pressure flash jet spinning is an important technology for preparing high-performance fibers and nonwoven materials. At present, two methods can be used for fiber formation: vertical jetting and horizontal jetting. Due to the high pressure, when vertical jetting is used, the fiber movement speed is too fast and the fibers cannot be effectively dispersed. The high-pressure flash jet mesh nano-micro fiber bundles cannot be evenly webbed, which will greatly reduce the performance of high-pressure flash jet nano-micro fiber nonwoven materials. Therefore, in actual production and experiments, horizontal jetting is mainly used for fiber formation, which requires a steering device to change the direction of fiber movement. After the steering device is used, the fiber movement speed can be greatly reduced, and the fibers can be initially dispersed, so that the fibers can be evenly laid in the subsequent process.

[0003] Patent No. CN114232212A discloses a flash spinning device based on a multidimensional steering plate and a spinning method thereof, which includes a box, a conveying device and a multidimensional steering plate, wherein N multidimensional steering plates are provided, and the N multidimensional steering plates are arranged between the spinneret and the conveying device and are arranged alternately from top to bottom on both sides. The flash spinning device uses N multidimensional steering plates to steer the fibers, and completely relies on the direct collision between the high-pressure flash-sprayed polymer jet and the steering device to achieve the guidance and dispersion of the fibers. However, in the process of guiding the fibers using this method, when the fibers collide with the multidimensional steering plate, the fibers will accumulate at the collision point and cannot be freely spread during the subsequent web formation, so the fibers cannot be evenly webbed, which also has a great impact on the performance of the high-pressure flash-sprayed nano-microfiber nonwoven material.

[0036] In order to have a clearer understanding of the technical features, purposes and effects of the present invention, the specific implementation methods of the present invention are now described in detail with reference to the accompanying drawings. In the following description, it should be understood that the directions or positional relationships indicated by "front", "back", "up", "down", "left", "right", "longitudinal", "horizontal", "vertical", "horizontal", "top", "bottom", "inside", "outside", "head", "tail", etc. are based on the directions or positional relationships shown in the accompanying drawings, are constructed and operated in a specific direction, and are only for the convenience of describing the present technical solution, rather than indicating that the device or element referred to must have a specific direction, and therefore cannot be understood as a limitation to the present invention.

[0037] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0038] Please refer to Figure 1 , this embodiment provides a steering device for steering the fibers ejected from the flash spinner, the steering device comprises a guide plate 10 and a steering plate 20, the guide plate 10 is arranged on one side of the flash spinner nozzle, and the guide plate 10 and the flash spinner are spaced a certain distance in the horizontal direction, the steering plate 20 is arranged on the side of the guide plate 10 away from the flash spinner, and is used to steering the fibers guided out of the guide plate 10. The steering plate 20 is provided with an arc-shaped steering surface 21 on the side facing the guide plate 10, and the steering surface 21 is bent in the direction of the guide plate 10. The top surface of the guide plate 10 is formed with a guide surface 11, and the guide surface 11 includes N curved surfaces connected in sequence, and the curvature radius of the N curved surfaces gradually decreases in the direction close to the steering plate; N is a natural number greater than or equal to 1. Among them, the curvature radius of the curved surface closest to the steering plate 20 is the same as the curvature radius of the steering surface 21.

[0039] Exemplarily, the steering device is used to redirect and disperse the fibers ejected from the flash spinneret, that is, after the spinning solution enters the flash spinneret, the solvent instantly foams and flashes, and the polymer of the spinning solution cools and solidifies to form a fiber bundle 30, which is ejected from the nozzle of the flash spinneret. The fiber bundle is carried by the high-pressure airflow toward the guide plate, so that the fiber bundle 30 falls on the guide surface 11 of the guide plate 10, and then the fiber bundle 30 moves along the guide surface 11 and disperses there, and then transitions to the steering plate 20 that is smoothly docked with the guide plate 10, and finally the steering surface on the steering plate 20 turns the dispersed fiber bundle 30 to the transfer device for collection. Among them, the high-pressure airflow carrying the fiber bundle to move toward the guide plate can be 5500m / min, so that the fiber bundle falling on the guide surface can be dispersed step by step.

[0040] Exemplarily, since the fluid moves along the surface of the curved surface when it contacts the curved surface, the fluid can be dispersed step by step. To this end, the guide surface 11 in this embodiment is formed by connecting N curved surfaces in sequence, which can effectively ensure that the fiber bundle 30 falling on the guide surface 11 can be dispersed step by step with better uniformity. In addition, the curvature radius of a curved surface closest to the steering plate 20 is set to be the same as the curvature radius of the steering surface 21 of the steering plate 20, ensuring that the scattered fiber bundles can be better guided and will not accumulate.

[0041] Exemplarily, the fiber bundle 30 is a spinning fluid made of a polymer, a solvent, and an air flow medium in a certain proportion; wherein the solvent can be one of dichloromethane, n-pentane, and cyclohexane, and the gas can be one of nitrogen, carbon dioxide, helium, and argon.

[0042] Exemplarily, since the guide surface is formed by connecting multiple curved surfaces in sequence, the fiber bundle will be transferred to the turning surface under the guidance of multiple curved surfaces. In order to ensure that the fiber bundle transitions more smoothly from the guide surface to the turning surface, the roughness of the surface closest to the turning plate needs to be kept consistent with the roughness of the turning plate. In this embodiment, the roughness of the turning plate Ra≤0.1. It should be noted that if the roughness of the turning plate and the curved surface closest to the turning plate is greater than 0.1, the refraction direction of the airflow is uncontrollable, a large amount of turbulence is generated, and the fiber splitting effect of the fiber bundle is affected.

[0043] In addition, it should be noted that the roughness of the steering plate and the curved surface closest to the steering plate is tested based on the testing standard of GB / T1031-2009. For details, reference may be made to the GB / T 1031-2009 standard for roughness in the prior art, and no limitation is made thereto.

[0044] The steering device based on the above technical features is provided with a guide plate 10 on one side of the nozzle of the flash spinner, and a guide surface 11 formed by N curved surfaces connected in sequence is formed on the top surface of the guide plate 10, so that the fiber bundles 30 falling on the guide surface 11 can be gradually dispersed according to the different curvature settings of the curved surface, which can effectively avoid the accumulation of the fiber bundles 30 at the impact point, resulting in the problem of subsequent inability to form a uniform web; in addition, a steering plate 20 is provided on the side of the guide plate 10 away from the flash spinneret, and a steering surface 21 is provided on the steering plate 20 which is arc-shaped and curved toward the guide plate 10, so that the scattered fiber bundles can be steered.

[0045] Example 1

[0046] Please refer to Figure 2 and Figure 3 In one embodiment, when N is equal to 1, the guide surface 11 is a circular arc surface 11a, and the curvature radius and curvature of the circular arc surface 11a and the curvature radius of the turning surface 21 satisfy the following relationship:

[0047] R0=R1

[0048] Wherein, R0 is the curvature radius of the arc surface 11 a , and R1 is the curvature radius of the turning surface 21 .

[0049] In one embodiment, the radius of curvature of the arc surface 11 a is between 3 cm and 15 cm, and the distance between two ends of the guide plate 10 in the horizontal direction is between 5 cm and 20 cm.

[0050] In order to facilitate the description of the function of the steering device in guiding and dispersing the ejected fiber bundle 30 when N is 1, the present embodiment is described with the radius of curvature of the arc surface 11a being 8 cm and the distance between the two ends of the guide plate in the horizontal direction being 10 cm, as follows:

[0051] Polyethylene, dichloromethane and carbon dioxide are prepared into spinning fluid in a certain proportion, and the temperature in the high-temperature and high-pressure reactor reaches 180°C and the pressure reaches 8MPa, so that the flash spinneret instantly foams and flashes, and forms a fiber bundle after cooling and solidification, and then ejects from the nozzle of the flash spinneret, and the fiber bundle moves to the guide surface 11 of the guide plate 10 under the carrying effect of the high-pressure airflow. Since the guide surface 11 is a circular arc surface 11a, the fiber bundle is gradually dispersed along the circular arc surface 11a, which can make the uniformity of the fiber bundle 30 better. In addition, a steering plate 20 is set on the side of the guide plate 10 away from the flash spinner, and the curvature radius of the steering surface 21 on the steering plate 20 is set to be the same as the curvature radius of the circular arc surface 11a, which can ensure that the dispersed fiber bundle 30 can be better guided and will not accumulate.

[0052] Example 2

[0053] Please refer to Figure 4 and Figure 5 In one embodiment, when N is equal to 2, the guide surface 11 is formed by connecting the first curved surface 11b and the second curved surface 11c, the first curved surface 11b is located on the side close to the steering plate 20, and the curvature radius of the first curved surface 11b, the second curved surface 11c and the curvature radius of the steering surface satisfy the following relationship:

[0054] R0=R1 <R2

[0055] Wherein, R1 is the curvature radius of the first curved surface 11 b , R0 is the curvature radius of the turning surface 21 , and R2 is the curvature radius of the second curved surface 11 c .

[0056] In one embodiment, the radius of curvature of the first curved surface 11 b is between 3 cm and 15 cm, and the radius of curvature of the second curved surface 11 c is between 5 cm and 20 cm.

[0057] In one embodiment, the distance between the two ends of the guide plate 10 in the horizontal direction is between 5 cm and 20 cm, and the height of the end of the guide plate 10 away from the turning plate 20 in the vertical direction is between 3 cm and 10 cm.

[0058] In order to facilitate the description of the function of the steering device in guiding and dispersing the ejected fiber bundle when N is 2, the curvature radius of the first curved surface 11b is 6 cm, the curvature radius of the second curved surface 11c is 9 cm, the distance between the two ends of the guide plate 10 in the horizontal direction is 15 cm, and the height of the end of the guide plate 10 away from the steering plate in the vertical direction is 5 cm, as described below:

[0059] Polyethylene, dichloromethane and carbon dioxide are prepared into a spinning fluid in a certain proportion, and the temperature in the high-temperature and high-pressure reactor reaches 180°C and the pressure reaches 8MPa, so that the flash spinneret instantly foams and flashes, and forms a fiber bundle 30 after cooling and solidification, and then is ejected from the nozzle of the flash spinneret. Under the carrying action of the high-pressure airflow, the fiber bundle 30 moves to the guide surface 11 of the guide plate 10. Since the guide surface 11 is formed by connecting the first curved surface 11b and the second curved surface 11c, and the first curved surface 11b is arranged on the side close to the deflection plate 20, the fiber bundle 30 flows from the second curved surface 11c to the first curved surface 11b in sequence, thereby further allowing the fiber bundle 30 to be dispersed step by step, which can make the fiber bundle 30 more uniform. In addition, a deflection plate 20 is arranged on the side of the guide plate 10 away from the flash spinner, and the curvature radius of the deflection surface 21 on the deflection plate 20 is set to be the same as the curvature radius of the first curved surface 11b, which can ensure that the dispersed fiber bundles 30 can be better guided without accumulation.

[0060] Example 3

[0061] Please refer to Figure 6 and Figure 7 In one embodiment, when N is equal to 3, the guide surface is formed by sequentially connecting the first curved surface 11b, the second curved surface 11c and the third curved surface 11d, the first curved surface 11b is located on the side close to the steering plate 20, the second curved surface 11c is located between the first curved surface 11b and the third curved surface 11d, and the curvature radius and curvature of the first curved surface 11b, the second curved surface 11c and the third curved surface 11d and the curvature radius and curvature of the steering surface satisfy the following relationship:

[0062] R0=R1 <R2<R3

[0063] Wherein, R0 is the curvature radius of the turning surface 21, R1 is the curvature radius of the first curved surface 11b, R2 is the curvature radius of the second curved surface 11c, and R3 is the curvature radius of the third curved surface 11d.

[0064] In one embodiment, the radius of curvature of the first curved surface 11b is between 3cm and 15cm, the radius of curvature of the second curved surface 11c is between 4cm and 16cm, and the radius of curvature of the third curved surface 11d is between 5cm and 20cm; the distance between the two ends of the guide plate 10 in the horizontal direction is between 5cm and 20cm, and the height of the end of the guide plate 10 away from the turning plate 20 in the vertical direction is between 3cm and 10cm.

[0065] In order to facilitate the description of the function of the steering device in guiding and dispersing the ejected fiber bundle 30 when N is 3, the curvature radius of the first curved surface 11b is 3 cm, the curvature radius of the second curved surface 11c is 6 cm, the curvature radius of the third curved surface 11d is 8 cm, the distance between the two ends of the guide plate 10 in the horizontal direction is 16 cm, and the height of the end of the guide plate 10 away from the steering plate 20 in the vertical direction is 5 cm. The specific description is as follows:

[0066] Polyethylene, dichloromethane and carbon dioxide are prepared into spinning fluid in a certain proportion, and the temperature in the high-temperature and high-pressure reactor reaches 180°C and the pressure reaches 8MPa, so that the flash spinneret instantly foams and flashes, and forms a fiber bundle after cooling and solidification, and then ejected from the nozzle of the flash spinneret. Under the carrying action of the high-pressure airflow, the fiber bundle moves to the guide surface of the guide plate 10. Since the guide surface 11 is composed of the first curved surface 11b, the second curved surface 11c and the third curved surface 11d connected in sequence, and the first curved surface 11b is arranged on the side close to the deflection plate 20, and the second curved surface 11c is located between the first curved surface 11b and the third curved surface 11d, the fiber bundle 30 flows in sequence from the third curved surface 11d, the second curved surface 11c and the first curved surface 11b, so as to further disperse the fiber bundle 30 step by step, which can make the fiber bundle 30 more uniform. In addition, a deflection plate 20 is arranged on the side of the guide plate 10 away from the flash spinner, and the curvature radius of the deflection surface 21 on the deflection plate 20 is set to be the same as the curvature radius of the first curved surface 11b, which can ensure that the dispersed fiber bundles can be better guided and will not accumulate.

[0069] In this embodiment, a flash spinneret is used for instantaneous foaming and flash evaporation, and after cooling and solidification, a fiber bundle is formed and ejected from the nozzle of the flash spinneret. Then, the fiber bundle is carried by the high-pressure airflow and moves to the guide surface of the guide plate for gradual dispersion. Finally, the dispersed fiber bundle is deflected by the steering surface on the deflection plate to the transfer device for collection, thereby making the fiber bundle more uniform and effectively avoiding the accumulation of the fiber bundle at the impact point, which leads to the problem of subsequent inability to form a uniform web.

[0070] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and substitutions can be made without departing from the technical principle of the present invention. These improvements and substitutions should also be regarded as the protection scope of the present invention.
