[0026] The dual-chamber spinning assembly and its associated equipment, including the vacuum filter assembly 2, thermostat assembly 3, and control assembly 4, are all in good condition. The equipment is preheated, with the inlet pipe 32 connected to the heating system and the outlet pipe 33 circulating heat, in preparation for receiving the molten nylon material. Based on the nylon material's characteristics and spinning requirements, controller 41 sets appropriate parameters, including temperature, pressure, and flow rate, to ensure the stability and continuity of the spinning process. The nylon material is heated to a molten state, ensuring good fluidity and plasticity. The molten nylon is then injected through the inlet end 10 of the dual-chamber pipe 1. Example 2
[0027] Based on the above Example 1, please refer to Figure 3 - Figure 5The constant temperature component 3 includes an insulation layer 30, which is equidistantly installed on the outside of the first-level decompression pipe 22 and the second-level decompression pipe 24. The inner wall of the insulation layer 30 and the outer surface of the first-level decompression pipe 22 and the second-level decompression pipe 24 form a constant temperature cavity 31. The inner wall of the insulation layer 30 is connected to the incoming pipe 32 and the outgoing pipe 33.
[0028] The access pipe 32 has four output ends and one input end, and the output ends of every two access pipes 32 form a group. The output ends of the two groups of access pipes 32 are arranged up and down and are interconnected with the inner walls of the two insulation layers 30. The outlet pipe 33 has four input ends and one output end, and the output ends of every two outlet pipes 33 form a group. The output ends of the two groups of outlet pipes 33 are arranged up and down and are interconnected with the inner walls of the two insulation layers 30.
[0029] The control assembly 4 includes a support plate 40 , which is installed below the double-lumen pipe 1 . A controller 41 is installed on one side of the support plate 40 , and a processor 42 is installed on one side of the support plate 40 .
[0030] The processor 42 and the controller 41 are electrically connected to each other, the processor 42 and the electronic pressure gauge 16 are electrically connected to each other, and the controller 41 and the electric valve 21 are electrically connected to each other.
[0031] It is detected that the pressure in chamber No. 14 is relatively high, and the data is transmitted to the processor 42. The processor 42 analyzes the data transmission command and sends it to the controller 41. The controller 41 controls the electric valve 21 on the right to open. The molten nylon is not filtered at this stage. After a part of the molten nylon flows out of chamber No. 14, the other part continues to be transported on the inner wall of the double-chamber pipe 1 and enters the first-level decompression pipe 22. The molten nylon will be filtered by two first-level filter plates 23 to remove impurities and particles. Since the pressure in chamber No. 14 is relatively high, the provision of two first-level filter plates 23 can ensure the filtration quality. The molten nylon that has undergone the first-level decompression and filtration treatment will enter chamber No. 2 15. The molten nylon will be further filtered by the second filter plate 13 to remove finer impurities and particles. If the electronic pressure gauge 16 detects that the pressure in chamber 2 15 is too high, exceeding a threshold, the processor 42 transmits data to the controller 41, which then controls the left electric valve 21 to open, distributing the molten nylon material within chamber 2 15. The remaining molten nylon material is then transported within the dual-lumen pipe 1. The molten nylon flowing out of chamber 2 15 enters the secondary decompression pipe 24. The molten nylon is then filtered by a secondary filter plate 25. Although the molten nylon has already been filtered by the first filter plate 12 within the dual-lumen pipe 1,
[0032] The working principle and use process of the present invention are as follows: Ensure that the dual-cavity spinning assembly and its ancillary equipment, including the pressure reducing filter assembly 2, the constant temperature assembly 3, the control assembly 4, etc., are in good condition, and preheat the equipment. The access pipe 32 is connected to the heating equipment, and the outlet pipe 33 will circulate the heating to prepare for receiving the molten nylon material. According to the characteristics of the nylon material and the spinning requirements, the controller 41 sets appropriate parameters such as temperature, pressure, flow, etc. to ensure the stability and continuity of the spinning process. The nylon raw material is heated to a molten state to ensure that it has good fluidity and plasticity. The molten nylon is injected from the inlet end 10 of the dual-cavity pipe 1. At this time, the molten nylon will first enter the No. 1 cavity 14.
[0033] Preliminary treatment and primary decompression and filtration of chamber No. 1 14: When the molten nylon passes through chamber No. 1 14, the electronic pressure gauge 16 will monitor its internal pressure in real time. If it is detected that the pressure in chamber No. 1 14 is relatively high, the data is transmitted to the processor 42. The processor 42 analyzes the data transmission command and sends it to the controller 41. The controller 41 controls the electric valve 21 on the right to open. The molten nylon is not filtered at this stage. After a part of the molten nylon flows out of chamber No. 1 14, the other part continues to be transported on the inner wall of the double-chamber pipe 1 and enters the primary decompression pipe 22. The molten nylon will be filtered by two primary filter plates 23 to remove impurities and particles therein. Since the pressure in chamber No. 1 14 is relatively high, the provision of two primary filter plates 23 can ensure the filtration quality and improve the purity of the spinning raw materials.
[0034] Further processing and secondary decompression and filtration in chamber No. 2 15: The molten nylon that has undergone primary decompression and filtration will enter chamber No. 2 15. The molten nylon will be further filtered by the second filter plate 13 to remove finer impurities and particles. If the electronic pressure gauge 16 detects that the pressure in chamber No. 2 15 is too high and exceeds the threshold, the processor 42 transmits data to the controller 41. The controller 41 controls the electric valve 21 on the left to open, sharing the nylon molten material inside chamber No. 2 15. The remaining nylon molten material is transported inside the dual-lumen pipe 1. The molten nylon flowing out of chamber No. 2 15 will enter the secondary decompression pipe 24. The molten nylon will be filtered by a secondary filter plate 25. Although the molten nylon has been filtered by the first filter plate 12 in the dual-lumen pipe 1, in order to ensure the filtration quality, a secondary filter plate 25 is still set in the secondary decompression pipe 24 for further filtration.
[0035] After primary and secondary decompression and filtration, the molten nylon converges at the outflow end 11 of the dual-lumen pipe 1. At this point, the molten nylon is ready for spinning. This convergence is then fed into the subsequent spinning equipment for spinning and shaping. Continuous monitoring and adjustment are performed: Throughout the spinning process, the pressure inside the dual-lumen pipe 1 and the decompression pipe is continuously monitored via an electronic pressure gauge 16. The parameters of the controller 41 and electric valve 21 are adjusted accordingly to ensure the stability and continuity of the spinning process.
