[0028] Example 1 like Figures 1-5 As shown, this embodiment provides a spinneret device including: a housing 1, an inlet seat 2, a spinneret plate 3, a mounting seat 4, a mating seat 5, and a rotating component 6; Please see Figure 4 and Figure 5 The outer contour of the shell 1 is cylindrical. The top of the shell 1 is provided with an installation groove 101, and the bottom of the shell 1 is provided with an outlet groove 102 that connects to the installation groove 101. Both the installation groove 101 and the outlet groove 102 are cylindrical grooves. The shell 1 serves as the basic structure of the entire device, and its interior forms a chamber for the flow and treatment of spinning solution. The shell 1 is preferably made of corrosion-resistant, high-strength stainless steel or alloy steel that has undergone surface hardening treatment to withstand the chemical corrosion that the spinning solution may bring and the working pressure inside the system. Please see Figure 2 and Figure 3 The inlet seat 2 is installed in the mounting groove 101, and the inlet seat 2 is provided with an inlet pipe 201 for the spinning solution to flow through. The inlet seat 2 serves as the first interface for the spinning solution to enter the device. The inlet seat 2 is detachably connected to the housing 1 for easy maintenance. The inlet seat 2 can be made of the same or similar material as the housing 1. A sealing ring (such as a polytetrafluoroethylene or fluororubber sealing ring) can be provided on the end face of the inlet seat 2 that contacts the housing 1 to ensure the sealing of the connection. Please see Figure 1 and Figure 3 The spinneret 3 is set in the outlet tank 102. The spinneret 3 is provided with multiple spinneret holes 301. When the spinning liquid reaches the outlet tank 102, it can be extruded through the multiple spinneret holes 301.

Please see Figure 3The mounting seat 4 is arranged between the guide seat 2 and the spinneret 3, and the connecting pipe 401 for the flow of the spinning solution is arranged on the mounting seat 4; the mounting seat 4 is also detachably connected with the shell 1, and the mounting seat 4 constitutes the support frame of the middle part of the device; Please refer to Figure 3 The matching seat 5 is arranged between the guide seat 2 and the mounting seat 4, and the intermediate pipe 501 for the flow of the spinning solution is arranged on the matching seat 5; the fluid channel for the continuous flow of the spinning solution is formed by the liquid inlet pipe 201, the intermediate pipe 501 and the connecting pipe 401, and the connecting cavity is formed between the matching seat 5 and the mounting seat 4; the matching seat 5 is used to connect the guide seat 2 and the mounting seat 4, and participates in constituting the connecting cavity for accommodating the rotating member 6; the contact surface between the matching seat 5 and the mounting seat 4 also needs to be well sealed; Please refer to Figure 4 and Figure 5 The rotating member 6 is a rotary body, and a plurality of distribution grooves 601 are arranged on the rotating member 6 in the circumferential direction; the profiles of the distribution grooves 601 gradually increase from the center of the rotating member 6; the distribution grooves 601 all have an inclined side wall, and the inclined directions of the side walls are towards the same circumferential direction; please refer to Figure 3 The rotating member 6 is movably arranged in the connecting cavity, and there is a gap between the rotating member 6 and the mounting seat 4; when the spinning solution flows through the distribution grooves 601, the rotating member 6 is driven to rotate in the connecting cavity, and the spinning solution is pushed outward from the center of the rotating member 6, so as to realize dynamic mixing and homogenization; Please refer to Figure 3 The filter plate 7 is arranged between the rotating member 6 and the matching seat 5; the filter plate 7 is in the form of a round cake as a whole, and a plurality of filter holes 701 are arranged on the filter plate 7; the matching seat 5 limits the filter plate 7 on the mounting seat 4, and there is a gap between the filter plate 7 and the rotating member 6; the filter plate 7 is mainly used to filter out impurities and incompletely dissolved gel particles in the spinning solution, so as to prevent the spinning holes 301 from being blocked or the normal operation of the rotating member 6 from being affected; the filter plate 7 can be made of metal sintered felt, multi-layer metal mesh or ceramic filter element, and the filtering precision can be selected according to the properties of the spinning solution; Please refer to Figure 3 and Figure 4 The side of the mounting seat 4 close to the matching seat 5 is provided with the connecting groove 402 for mounting the rotating member 6; after the rotating member 6 is mounted in the connecting groove 402, there is a gap between the side wall of the rotating member 6 and the side wall of the connecting groove 402; in particular, the connecting pipe 401 passes through the center of the bottom surface of the connecting groove 402, and the bottom surface of the connecting groove 402 is a slope surface inclined towards the center; this is convenient for guiding the spinning solution, and the bottom surface of the rotating member 6 is matched with the bottom surface of the connecting groove 402; the opening of the connecting groove 402 is provided with the annular groove 403 for mounting the filter plate 7, and the diameter of the annular groove 403 is slightly larger than the diameter of the filter plate 7; the bottom edge of the filter plate 7 is in contact with the bottom surface of the annular groove 403; please refer to Figure 3 andFigure 5 The side of the fitting seat 5 close to the mounting seat 4 is provided with a pressing ring 502, which is in contact with the filter plate 7; this structure design makes the filter plate 7 be firmly pressed and fixed, and the rotating part 6 is limited in the connecting groove 402, which can freely rotate and will not move axially; When the spinning solution flows through the inclined side wall of the flow distribution groove 601, the spinning solution generates a fluid dynamic pressure on the side wall of the flow distribution groove 601, and the tangential component of the pressure constitutes a driving torque, thereby driving the rotating part 6 to rotate around its axis. The centrifugal force generated by the rotation of the rotating part 6 is coupled with the flow guiding effect of the inclined side wall, and together they uniformly accelerate the spinning solution that hits the center of the top surface of the rotating part 6 from the center to the periphery. In this process, strong shearing and mixing effects are exerted on the spinning solution. At the same time, since the rotating part 6 is not limited in the connecting cavity, after the spinning solution passes through the gap between the rotating part 6 and the side wall of the connecting groove 402, the rotating part 6 will be lifted by the spinning solution, causing the bottom surface of the rotating part 6 to have a gap with the bottom surface of the connecting groove 402. At this time, the spinning solution can enter the connecting pipe 401 along the bottom surface of the connecting groove 402. This design increases the flow area of the spinning solution, reduces the flow resistance, and at the same time ensures the dynamic stability of the rotating part 6 during high-speed rotation, avoiding rigid friction with the base; In this embodiment, the radial gap between the rotating part 6 and the side wall of the connecting groove 402, and the axial gap between the filter plate 7 and the rotating part 6, are both configured to ensure that the rotating part 6 can freely rotate without obstruction under fluid driving, and can effectively limit its excessive radial and axial movement. As an example, the gap range can be between 0.5mm and 3mm, which is adjusted according to the spinning solution viscosity and working pressure; In this embodiment, the mounting seat 4 and the lead-in seat 2 are detachably connected with the shell 1. For example, please refer to Figure 4 and Figure 5 The outer wall of the shell 1 is provided with a fastening platform 8 corresponding to the positions of the mounting seat 4 and the lead-in seat 2. The fastening platform 8 is provided with a mounting hole 801, which penetrates the outer wall of the shell 1 along the radial direction of the shell 1. The side wall of the mounting seat 4 and the lead-in seat 2 is provided with a threaded hole 802. A threaded fastener (such as an internal hexagonal bolt) can pass through the mounting hole 801 and be screwed with the threaded hole 802, thereby realizing the fastening of the mounting seat 4 or the lead-in seat 2 in the shell 1. This lateral fastening method avoids the setting of flange connection at the top or bottom of the device, making the structure more compact and the sealing surface less; Please refer to Figure 3 The lead-in seat 2 presses the fitting seat 5 against the mounting seat 4, so that the fitting seat 5 limits the filter plate 7 on the mounting seat 4. This assembly method of layer-by-layer pressing makes the entire internal component (fitting seat 5, filter plate 7, rotating part 6) can be taken out as a whole by disassembling the lead-in seat 2 and the mounting seat 4, greatly facilitating maintenance and component replacement; Please refer to Figure 1 and Figure 5 The side wall of the outlet slot 102 is provided with a positioning slot 901 penetrating the bottom surface of the shell 1, and the side wall of the spinneret 3 is provided with a positioning block 902 capable of entering the positioning slot 901, the positioning block 902 is detachably connected with the positioning slot 901 through a threaded fastener, and the fastening mode of the positioning block 902 and the positioning slot 901 can also adopt a side fastening mode, which ensures the circumferential positioning accuracy of the spinneret 3 during installation, prevents it from rotating during operation, and facilitates quick disassembly, cleaning or replacement; Please refer to Figures 1-5 The outer wall of the shell 1 is provided with a mounting connector 10 capable of connecting an external cleaning liquid supply device; the mounting connector 10 penetrates the outer wall of the shell 1, and the lead-in seat 2 is provided with a cleaning pipe 11 communicating with the liquid inlet pipe 201, and the cleaning pipe 11 is connected with the mounting connector 10; a one-way valve 12 is arranged in the cleaning pipe 11, which is opened to the liquid inlet pipe 201 and closed in the opposite direction, and the arrangement of the one-way valve 12 makes the spinning solution not enter the cleaning pipe 11 after entering the liquid inlet pipe 201, and the cleaning liquid can enter the liquid inlet pipe 201 through the one-way valve 12, which realizes the online cleaning function of the device without disassembly; when cleaning is needed, the main spinning solution supply is closed, the cleaning liquid supply device is connected, the cleaning liquid enters the main fluid passage under the guidance of the one-way valve 12 through the mounting connector 10 and the cleaning pipe 11, and the inside of the device is thoroughly flushed; When the spinning device of the embodiment works, the spinning solution is delivered by the metering pump, enters the intermediate pipe 501 of the matching seat 5 from the liquid inlet pipe 201 of the lead-in seat 2, and then passes through the filter holes 701 of the filter plate 7 to enter the connecting cavity; in the connecting cavity, the spinning solution impacts the inclined side wall of the flow dividing groove 601 of the rotating part 6, drives the rotating part 6 to rotate at high speed, and under the joint action of centrifugal force and shear force, the spinning solution is fully homogenized, then continues to move forward through the gap between the rotating part 6 and the mounting seat 4, enters the connecting pipe 401 along the inclined bottom surface of the connecting groove 402, and finally reaches the outlet slot 102 and is uniformly extruded from the hundreds of micron-level spinneret holes 301 of the spinneret 3; the extruded fine stream enters the coagulation bath to solidify and form the primary fiber.
