[0023] Referring to Figure 3 and Figure 4 As shown in the figure, a turbine connecting piece 10 is installed at the joint of the discharge pipe 5 and the hollow disc 1, and a turbine 11 is arranged in the turbine connecting piece 10. In the specific implementation process, the turbine 11 is arranged to further stir and mix the materials when the spinning dope flows out of the hollow disc 1 through the rotation of the turbine 11, so as to ensure that the spinning dope and the ammonia gas are more uniformly mixed.
[0024] Referring to Figure 2 and Figure 4 As shown in the figure, flange bolts 9 are installed around the top of the matching flange 2 at equal intervals, bolt holes 12 matched with the flange bolts 9 are arranged outside the cavity in the hollow disc 1, the hollow disc 1 and the matching flange 2 are detachably connected through the flange bolts 9, and a flange pad 13 is installed at the joint of the hollow disc 1 and the matching flange 2.

[0025] Referring to Figure 4As shown, a visualization window 14 is provided on the outer wall of the hollow disc 1, and the visualization window 14 is made of transparent acrylic material. In the specific implementation process, through the visualization window 14, the operator can observe the mixing of spinning solution and ammonia inside the hollow disc 1 in real time. This helps to detect abnormal problems in the mixing process in a timely manner, such as uneven mixing or blockage, thereby ensuring the stability and controllability of the production process.
[0026] See Figure 1 As shown, a controller is installed on the outside of the hollow disc 1. The output of the controller is electrically connected to the pressure sensor 6, the pressure regulating valve 7, the gear pump 8, and the input of the turbine 11. In practice, the controller allows operators to easily monitor and adjust the entire mixing process. The pressure sensor 6 monitors the ammonia pressure in the ammonia feed pipe 3 in real time to ensure a stable supply of ammonia. The pressure regulating valve 7 automatically adjusts the ammonia supply pressure based on the feedback from the pressure sensor 6 to meet process requirements. The gear pump 8 precisely controls the flow rate of material through the feed pipe 3 to ensure the ratio of material to ammonia. The controller adjusts the speed of the turbine 11 to optimize the mixing effect.
[0027] Working principle:
[0028] Step 1: The spinning solution is introduced into the cavity of the hollow disc 1 through the feed pipe 3. The gear pump 8 installed on the feed pipe 3 is used to precisely control the flow rate of the spinning solution, so that the spinning solution flows into the cavity at a certain rate. This step is the basis of the mixing process. At the same time, ammonia gas is introduced into the cavity of the hollow disc 1 through the ammonia gas output pipe 4 to mix with the spinning solution. On the ammonia gas output pipe 4, the pressure sensor 6 monitors the pressure of the ammonia gas in real time to ensure a stable supply of ammonia gas. According to the feedback of the pressure sensor 6, the pressure regulating valve 7 automatically adjusts the supply pressure of ammonia gas to meet the process requirements and ensure that the ammonia gas and the spinning solution are mixed under suitable conditions.
[0029] Step 2: After the spinning solution and ammonia enter the cavity of the hollow disc 1, they begin to mix within the cavity. Because the hollow disc 1 has a hollow internal structure, it provides sufficient space for the mixing of the spinning solution and ammonia. During the mixing process, the spinning solution and ammonia come into contact with and diffuse into each other within the cavity, gradually achieving a uniform mixture. To further enhance the mixing effect, a turbine connector 10 is installed at the junction of the discharge pipe 5 and the hollow disc 1. The turbine connector 10 contains a turbine 11. When the uniformly mixed spinning solution flows out of the hollow disc 1 through the discharge pipe 5, the turbine 11 rotates accordingly, further stirring and mixing the materials. In addition, a matching flange 2 is installed on the top of the hollow disc 1, and is detachably connected to the hollow disc 1 via flange bolts 9. During operation, the operator can observe the mixing of the spinning solution and ammonia inside the hollow disc 1 in real time through the visualization window 14 on the outer wall of the hollow disc 1.
