[0002] When producing chemical fibers, the raw materials are first heated and melted by an extruder, and then extruded through a metering pump onto a spinneret plate to form filaments, achieving spinning. The spun chemical fibers are cooled and solidified after passing through the duct, and finally wound and collected by a winding mechanism. In order to improve the cooling efficiency of the duct, a temperature reduction or cooling device is usually provided on the duct.

A water inlet pipe and a water outlet pipe are connected to the sleeve, and the water inlet pipe and the water outlet pipe are arranged vertically. A stirring mechanism is arranged inside the sleeve, and the stirring mechanism is located between the water inlet pipe and the water outlet pipe. This rapid temperature reduction device for a spinning duct improves the temperature reduction speed of spinning and the duct. Moreover, during the temperature reduction process, by stirring the water from multiple angles, the temperature reduction speed can be further improved. In addition, by using the water cooling method for temperature reduction, it can avoid the phenomenon that adjacent spun fibers are easily adhered together and form double filaments. However, in the prior art, when the water flow rate is low, the paddle blades are difficult to rotate, so the stirring of the water flow cannot be achieved, and the cooling effect is difficult to guarantee.

[0029] As Figure 1-7 shown, a spinning channel cooling device in this embodiment includes a casing 1, a water inlet pipe 2 and a water outlet pipe 3 are arranged on the casing 1, the water inlet pipe 2 and the water outlet pipe 3 are distributed along the length direction of the casing 1, both ends of the casing 1 bulge inwards to form a sealing part 4. During the use of this spinning channel cooling device, the casing 1 is coaxially sleeved on the outer peripheral wall of the spinning channel 5, and both ends of the casing 1 are hermetically and fixedly connected to the outer peripheral wall of the spinning channel 5 through the sealing part 4. There is a gap between the inner peripheral wall of the casing 1 and the spinning channel 5, and this gap is the cooling cavity. When cooling, the water inlet pipe 2 is connected to the water supply system, and the water outlet pipe 3 is connected to the recovery system. Cooling water is conveyed from the water inlet pipe 2 to the cooling cavity through the water supply system, and the cooling water in the cooling cavity is then conveyed to the recovery system from the water outlet pipe 3. When the spinning passes through the channel, the heat on the spinning is transferred to the spinning channel 5, and the heat on the spinning channel 5 is transferred to the cooling water in the cooling cavity. The cooling water absorbs heat and then is discharged to realize the cooling of the spinning channel 5;

[0030] An auxiliary mechanism 6 is arranged inside the casing 1. The auxiliary mechanism 6 is located between the water inlet pipe 2 and the water outlet pipe 3. The auxiliary mechanism 6 includes a first fixing ring 61 and a second fixing ring 62. The first fixing ring 61 and the second fixing ring 62 are distributed at intervals up and down. The first fixing ring 61 and the second fixing ring 62 are both coaxially distributed with the casing 1. The outer peripheral wall of the first fixing ring 61 is hermetically and fixedly connected to the inner wall of the casing 1. The outer diameter of the second fixing ring 62 is smaller than the inner diameter of the casing 1. The inner diameter of the first fixing ring 61 is larger than the inner diameter of the second fixing ring 62 and smaller than the outer diameter of the second fixing ring 62. During the use of this spinning nozzle cooling device, both the first fixing ring 61 and the second fixing ring 62 are sleeved on the outer wall of the spinning nozzle 5. There is a gap between the inner peripheral wall of the first fixing ring 61 and the spinning nozzle 5. The inner peripheral wall of the second fixing ring 62 is hermetically and fixedly connected to the outer peripheral wall of the spinning nozzle 5. When the cooling water flows in the cooling cavity, the cooling water sequentially flows in the gap between the first fixing ring 61 and the spinning nozzle 5, the gap between the first fixing ring 61 and the second fixing ring 62, and the gap between the second fixing ring 62 and the casing 1. That is, the cooling water flows in an S shape along the length direction of the casing 1 inside the casing 1. During the turning process of the cooling water, the stirring of the cooling water is realized, so that the heat absorbed by the cooling water is evenly distributed, improving the heat absorption capacity of the cooling water, that is, ensuring the cooling effect of the spinning nozzle 5;

[0031] A plurality of first through holes 63 are arranged on the first fixing ring 61. The plurality of first through holes 63 are circumferentially and evenly distributed around the axis of the first fixing ring 61. A plurality of second through holes 64 are arranged on the second fixing ring 62. The plurality of second through holes 64 are circumferentially and evenly distributed around the axis of the second fixing ring 62. When the cooling water flows in an S shape along the length direction of the casing 1 inside the casing 1, a part of the cooling water sequentially passes through the first through holes 63 and the second through holes 64, so that the cooling water passing through the first through holes 63 and the second through holes 64 in sequence collides with the cooling water flowing radially along the casing 1 between the first fixing ring 61 and the second fixing ring 62. That is, the stirring effect of the cooling water is improved, thereby improving the cooling effect;

[0032] The distance between the first through hole 63 and the axis of the casing 1 is smaller than the distance between the second through hole 64 and the axis of the casing 1, which is convenient for the cooling water passing through the first through hole 63 and the second through hole 64 to flow in an S shape along the diameter direction of the casing 1, improving the stirring effect;

[0033] The plurality of first through holes 63 and the plurality of second through holes 64 are staggered, which is convenient for the cooling water passing through the first through hole 63 and the second through hole 64 to flow in an S shape along the length direction of the casing 1, improving the stirring effect;

[0034] A plurality of the first fixing rings 61 and a plurality of the second fixing rings 62 are provided. The plurality of first fixing rings 61 and the plurality of second fixing rings 62 are staggered along the length direction of the casing 1;

[0035] A plurality of support rods 65 are arranged between the first fixing ring 61 and the second fixing ring 62. The two ends of the support rod 65 are respectively detachably and fixedly arranged on the first fixing ring 61 and the second fixing ring 62. The plurality of support rods 65 are circumferentially and uniformly distributed around the axis of the sleeve 1. The strength of the first fixing ring 61 and the second fixing ring 62 is improved through the support rods 65, preventing the first fixing ring 61 and the second fixing ring 62 from deforming under the scouring of water flow;

[0036] In summary, the cooling water flows successively through the gap between the first fixing ring 61 and the spinning nozzle 5, the gap between the first fixing ring 61 and the second fixing ring 62, and the gap between the second fixing ring 62 and the sleeve 1, that is, the cooling water flows in an S shape along the length direction of the sleeve 1 inside the sleeve 1. During the turning process of the cooling water, the stirring of the cooling water is realized, so that the heat absorbed by the cooling water is evenly distributed, improving the heat absorption capacity of the cooling water, that is, ensuring the cooling effect of the spinning nozzle 5. Moreover, the cooling water passing through the first through hole 63 and the second through hole 64 in sequence collides with the cooling water flowing radially along the sleeve 1 on the first fixing ring 61 and the second fixing ring 62, that is, enhancing the stirring effect of the cooling water, thereby enhancing the cooling effect.
