[0046] The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, wherein the accompanying drawings constitute a part of the present invention and are used together with the embodiments of the present invention to illustrate the principles of the present invention, and are not used to limit the scope of the present invention.

[0047] Example

[0048] A specific embodiment of the present invention discloses a spinning system, such as Figure 1 As shown, it includes a spinning liquid storage tank 100, a vacuum degassing device 200 and a spinning device 300 connected in sequence; the vacuum degassing device 200 includes a degassing component 210, a driving shaft 220 and a limiting portion 230; the degassing component 210 includes an outer rotating cylinder 211 and a dispersion plate 212 connected to the driving shaft 220, which are arranged in sequence from the outside to the inside; a gap is arranged between the outer rotating cylinder 211 and the dispersion plate 212; the limiting portion 230 arranged below the dispersion plate 212 includes an annular blocking member 231 connected to the driving shaft 220; in the radial direction of the driving shaft 220, the outer edge of the annular blocking member 231 is located between the outer rotating cylinder 211 and the dispersion plate 212.

[0049] In this embodiment, a vacuum degassing device 200 is provided between the spinning solution storage tank 100 and the spinning device 300 to achieve degassing of the spinning solution before the spinning process, thereby preventing bubbles in the spinning solution from affecting the spinning quality and achieving the purpose of spinning quality.

[0050] In a vacuum environment, this embodiment uses the dispersion plate 212 to fling the fluid onto the inner wall of the outer rotating cylinder 211. The fluid then spirals downward along the inner wall of the outer rotating cylinder 211. During this motion, the centrifugal force of the gas is less than that of the liquid. Combined with the forces in the vacuum environment, the gas moves more easily toward the drive shaft 220 than the liquid, allowing bubbles to escape from the fluid. Compared to existing static degassing devices, this reduces degassing time and improves degassing efficiency.

[0051] In this embodiment, when the vacuum degassing device 200 is completed and a part of pure liquid fluid exists, the pure liquid fluid can be transported to the spinning device 300 for spinning. At the same time, the vacuum degassing device 200 can continue the degassing operation, that is, degassing and spinning at the same time, which significantly saves the spinning process time and improves work efficiency.

[0052] In this embodiment, a limiting portion 230 having an annular blocking member 231 is provided, and in the radial direction of the drive shaft 220, the outer edge of the annular blocking member 231 extends between the outer rotating cylinder 211 and the dispersion plate 212, so that the outer edge of the annular blocking member 231 extends into the fluid layer on the inner wall of the outer rotating cylinder 211. By limiting the speed of the fluid's spiral downward movement, the time the fluid is centrifuged on the inner wall of the outer rotating cylinder 211 is extended, thereby improving the centrifugal degassing effect and achieving the purpose of complete degassing.

[0053] Furthermore, the limiting portion 230 further includes a first connecting member 232, such as Figure 2 As shown, the annular barrier 231 is connected to the drive shaft 220 via a first connecting member 232, so that the annular barrier 231 moves synchronously with the drive shaft 220, throwing the fluid on the annular barrier 231 onto the inner wall of the outer rotating cylinder 211 for centrifugal degassing. The first connecting member 232 is rod-shaped or strip-shaped, and a gap is provided between two adjacent first connecting members 232 to reduce counterweight and provide a removal channel for bubbles between the dispersion plate 212 and the annular barrier 231.

[0054] Furthermore, considering the position adjustment of the limiting portion 230 on the outer wall of the driving shaft 220, the vacuum degassing device 200 further includes an axial position adjustment component 250, such as Figure 2 As shown, through the axial position adjustment assembly 250, the first connecting member 232 is connected to the drive shaft 220, driving the limiter 230 to perform linear reciprocating motion along the axial direction of the drive shaft 220, reaching the target position and locking, thereby achieving the purpose of adjusting the position of the limiter 230 on the outer wall of the drive shaft 220. More specifically, the axial position adjustment assembly 250 includes an adjustment member 251, a retaining member 252, and a second connecting member 253, which are sequentially connected along the outer wall of the drive shaft 220; the second connecting member 253 is connected to the first connecting member 232. The adjusting member 251 and the second connecting member 253 are respectively threadedly connected to the drive shaft 220, and the retaining member 252 is respectively connected to the adjusting member 251, the second connecting member 253, and the drive shaft 220. During the rotational motion, the adjusting member 251, the retaining member 252, the second connecting member 253, and the drive shaft 220 are relatively stationary, thereby allowing the annular blocking member 231 to rotate synchronously with the drive shaft 220, so that the fluid on the annular blocking member 231 can also be thrown onto the inner wall of the outer rotating cylinder 211 for centrifugal degassing. In this embodiment, the retaining member 252 is preferably a retaining washer. The adjusting member 251 is preferably a round nut.

[0055] Furthermore, considering that the degassing assembly 210 needs to work in the vacuum ring, the vacuum degassing device 200 further includes a reaction vessel 240 having a cavity 241, and the cavity 241 includes an upper mounting area and a lower liquid storage area; the degassing assembly 210, the drive shaft 220 and the limit portion 230 are arranged in the upper mounting area, such as Figure 1 shown.

[0056] In this embodiment, the degassing assembly 210 is arranged in the cavity 241 , the cavity 241 is formed into a closed cavity, and vacuum treatment is then performed to construct a vacuum environment that is conducive to the degassing operation of the degassing assembly 210 .

[0057] Furthermore, the reaction vessel 240 further includes a hollow boss 242 for supporting the drive shaft 220, such as Figure 1 As shown, the hollow boss 242 is disposed in the cavity 241 and connected to the bottom surface of the reaction vessel 240. A driver magnetically connected to the drive shaft 220 is arranged in the hollow of the hollow boss 242, thereby reducing the volume of the vacuum degassing device 200 and the space occupied by the vacuum degassing device 200.

[0058] Furthermore, in order to ensure the synchronous movement of the outer rotating cylinder 211 and the dispersion plate 212 during the degassing process, in this embodiment, the outer rotating cylinder 211 and the dispersion plate 212 are directly on the drive shaft 220. Alternatively, the degassing assembly 210 further includes a connecting rod 213; through the connecting rod 213, the inner wall of the straight section of the outer rotating cylinder 211 is connected to the dispersion plate 212, as shown in FIG. Figure 2 As shown, the outer rotating cylinder 211, the dispersion plate 212 and the driving shaft 220 are rotated synchronously.

[0059] Furthermore, considering the buffering of the fluid at the liquid inlet end of the spinning device 300, the spinning system of this embodiment further includes a buffer 400, such as Figure 1 As shown, the buffer 400 is connected between the vacuum degassing device 200 and the spinning device 300 .

[0060] Furthermore, considering the control of the amount of fluid entering the liquid inlet end of the spinning device 300, the spinning system of this embodiment further includes a metering pump 500, such as Figure 1 As shown; the metering pump 500 is connected between the buffer 400 and the spinning device 300.

[0061] Furthermore, the spinning device 300 includes a housing 310 having a working chamber, a spinning mechanism 320 and a winding mechanism 330 arranged in the working chamber and connected to the inner wall of the housing 310, as shown in FIG. Figure 1 The measured degassed fluid is transferred to the spinning mechanism 320 and then ejected from the spinning holes of the spinning mechanism 320. Finally, it is wound by the winding mechanism 330 for further processing or directly used to manufacture textiles.

[0062] In this embodiment, n spinning devices 300 are provided, where n is greater than or equal to 2, and the n spinning devices 300 are connected to the vacuum degassing device 200 through a metering pump 500 and a buffer 400, respectively. Figure 3As shown, with this arrangement, the fluid is continuously degassed online by the vacuum degassing device 200 and then directly transported to the multiple spinning devices 300 for spinning. When the spinnerets of the multiple spinning devices 300 have different spinneret hole specifications, it is possible to simultaneously produce spinning of various specifications without stopping the degassing process, thereby improving the spinning efficiency.

[0063] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any changes or replacements that can be easily thought of by any technician familiar with this technical field within the technical scope disclosed in the present invention should be covered by the protection scope of the present invention.
