Description

Technical Field

[0001] This utility model relates to the field of textile chemical equipment technology, and in particular to a laminar flow reaction chamber suitable for continuous spinning. Background Technology

[0002] In traditional continuous spinning reaction chamber environments, the interaction between the viscose filaments and the coagulation bath presents significant drawbacks. Due to the high friction between them, this friction becomes a key factor hindering smooth production when attempting to increase spinning speed to improve efficiency. Excessive friction directly leads to easy breakage of monofilaments during spinning, not only reducing product yield but also increasing production costs, as the cleaning and respinning processes after breakage consume additional manpower, resources, and time.

[0003] Furthermore, the impact force generated when the acid bath comes into contact with the viscose filaments has a significant negative impact on filament forming. The impact of the acid bath acts on the viscose filaments, disrupting the originally uniform forming process and causing disorder during the forming process. This disorder makes it difficult for the viscose filaments to uniformly coat with the acid bath solution, resulting in uneven chemical reactions within the filaments and ultimately affecting the quality of the viscose filaments. Moreover, uneven forming and reaction lead to fluctuations in the strength, toughness, color, and feel of the filaments, failing to meet the standards for high-quality viscose filaments.

[0004] These combined issues severely limit the spinnability of viscose filament production using existing reaction chambers. Therefore, a new structural design mitigates the impact of the acid bath on the viscose filaments, ensuring the stability and uniformity of the filament formation, thereby improving the spinnability of viscose filaments and the quality of the final product. Utility Model Content

[0005] To address the shortcomings of the existing technology, this invention provides a laminar flow reaction chamber suitable for continuous spinning that can stably and uniformly acid bath viscose filaments.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a laminar flow reaction chamber suitable for continuous spinning, comprising a chamber body and an adhesive tube disposed within the chamber body. An acid inlet channel is provided on the side of the chamber body, and an adhesive inlet channel is provided at the bottom of the chamber body. An annular guide plate is provided within the chamber body, with a gap between the guide plate and the inner wall of the chamber body. A conical plate is provided at the top of the chamber body, converging towards the axis of the chamber body. The upper end of the conical plate has a yarn outlet, and a laminar flow reaction zone is formed between the yarn outlet and the bottom of the conical plate. The adhesive tube extends into the laminar flow reaction zone and is equipped with a spinneret. The lower edge of the guide plate extends downwards into or beyond the acid inlet channel to buffer the impact force of the acid bath. The guide plate surrounds the outside of the spinneret. Acid is input into the chamber body through the acid inlet channel and flows to the laminar flow reaction zone through the outlet formed by the lower edge of the guide plate and the chamber body.

[0007] Furthermore, the cross-section of the guide plate is L-shaped, and the upper end of the guide plate is connected to the chamber body, forming an acid bath flow path between the acid inlet channel, the guide plate, and the chamber body.

[0008] Furthermore, the guide plate and the conical plate are integrally connected, and an upper limit cover is installed at the upper end of the hopper. The guide plate and the conical plate are installed on the hopper through the upper limit cover, and the conical plate passes through the upper limit cover.

[0009] Furthermore, the spinneret nozzle is higher than the upper surface of the guide plate, and the filament bundle is stretched from the spinneret nozzle to the outlet.

[0010] Furthermore, the spinneret nozzle is directly opposite the filament outlet.

[0011] Furthermore, a sealing ring is provided between the guide plate and the chamber body.

[0012] Furthermore, a lower limit cap is installed at the lower end of the container body, and the adhesive tube is installed on the container body through the lower limit cap, with the lower end of the adhesive tube passing through the lower limit cap.

[0013] Furthermore, the conical plate is made of a transparent material.

[0014] In summary, this utility model has the following beneficial effects:

[0015] (1) The laminar flow reaction chamber is designed with an acid inlet channel on the side of the chamber and an adhesive inlet channel at the bottom, which enables the acid bath and adhesive to enter the chamber in an orderly manner. The annular guide plate in the chamber is separated from the inner wall of the chamber. The top of the chamber converges towards the axis to form a conical plate, and a laminar flow reaction zone is formed between the filament outlet and the spinneret, forming a specific acid bath flow path. The lower end of the guide plate forms an opening for the acid liquid to flow into the chamber. The lower edge of the guide plate extends downward and is located within the axial projection range of the acid inlet channel or beyond the range of the acid inlet channel, forming an annular enclosure for the acid liquid entering the chamber through the acid inlet channel to buffer the acid liquid impact and change the acid liquid flow direction, so that the acid liquid flows from the opening to the reaction zone. In this way, the acid bath can be guided to flow in the chamber according to the designed route, avoiding the adverse effects of the chaotic flow of the acid bath on the laminar flow reaction zone. At the same time, the acid liquid is laminarly wrapped in the filament bundle in the conical area formed by the conical plate, ensuring that the acid bath and the filament bundle react fully and stably in the laminar flow reaction zone.

[0016] (2) The cross-section of the guide plate is L-shaped, with the upper end connected to the chamber and the lower edge extending to the acid inlet channel, so that a complete and efficient acid bath flow path can be formed between the acid inlet channel, the guide plate and the chamber. This allows the acid bath to enter from the acid inlet channel and flow smoothly along the path between the guide plate and the chamber to the laminar flow reaction zone, ensuring the supply and distribution of the acid bath is uniform, which is beneficial to improving the forming quality of the filament.

[0017] (3) The guide plate and the cone plate are connected as a whole and installed on the tank body through the upper limit cap, while the adhesive tube is installed in the tank body through the lower limit cap. This design enhances the integrity and stability of the structure and facilitates disassembly and assembly. Attached Figure Description

[0020] The present invention will be further described in detail below with reference to the embodiments.

[0021] Example 1:

[0022] In practical implementation: such as Figure 1As shown, a laminar flow reaction chamber suitable for continuous spinning includes a chamber body 1 and an adhesive tube 2 disposed within the chamber body 1. The side of the chamber body 1 has an acid inlet channel 11, and the bottom of the chamber body 1 has an adhesive inlet channel 12. An annular guide plate 4 is disposed inside the chamber body 1, with a gap between the guide plate 4 and the inner wall of the chamber body 1. The top of the chamber body 1 has a conical plate 5 that converges towards the axis of the chamber body 1. The upper end of the conical plate 5 has a yarn outlet 51, and a laminar flow reaction zone 6 is formed between the yarn outlet 51 and the bottom of the conical plate. The adhesive tube 2 extends into the laminar flow reaction zone 6 and is equipped with a spinneret 3. The lower edge of the guide plate 4 extends downward into or beyond the range of the acid inlet channel 11 to buffer the impact force of the acid bath. The guide plate 4 surrounds the outside of the spinneret 3.

[0023] The acid solution is introduced into the chamber 1 through the acid inlet channel 11 and flows to the laminar flow reaction zone 6 through the outlet formed by the lower edge of the guide plate 4 and the chamber 1. Specifically, the laminar flow reaction chamber has an acid inlet channel 11 on the periphery of the chamber 1 and a glue inlet channel 12 at the bottom. The annular guide plate 4 inside the chamber 1 is spaced from the inner wall of the chamber 1, changing the flow direction of the acid bath entering the chamber 1 through the acid inlet channel 11. The acid bath flows along the annular guide plate 4 and the bottom of the chamber 1 into the laminar flow reaction zone 6 above the chamber 1. The spinneret 3 is located in this laminar flow reaction zone 6. This avoids the acid bath directly impacting the filament bundle 31 ejected by the spinneret 3, which would cause chaos in the flow of the acid bath in the chamber 1 and affect the quality of the acid solution wrapped in the filaments. This laminar flow of acid solution wrapped in the filament bundle 31 within the conical area ensures a full and stable reaction between the acid bath and the viscose filaments in the laminar flow reaction zone 6, thereby improving the quality of the viscose filaments produced.

[0024] Example 2;

[0025] like Figure 1 As shown, based on the laminar flow reaction chamber suitable for continuous spinning in Example 1, the cross-section of the guide plate 4 is L-shaped. The upper end of the guide plate 4 is connected to the chamber body 1, and the lower edge of the guide plate 4 extends downward to the acid inlet channel 11. The spinneret 3 is vertically offset from the acid inlet channel 11 to ensure that the spinneret 3 is located in the reaction zone and to avoid direct impact on the filament bundle by the acid liquid along the axial direction of the acid inlet channel 11. An acid bath flow path is formed between the acid inlet channel 11, the guide plate 4, and the chamber body 1.

[0026] The guide plate 4 has an L-shaped cross-section, with its upper end connected to the chamber 1 and its lower edge extending to the acid inlet channel 11. This allows a complete and efficient acid bath flow path to be formed between the acid inlet channel 11, the guide plate 4, and the chamber 1. After entering through the acid inlet channel 11, the acid bath flows smoothly along the path between the guide plate 4 and the chamber 1 to the laminar flow reaction zone 6, ensuring uniform supply and distribution of the acid bath, which is beneficial for improving the forming quality of the filament.

[0027] During implementation, the spinneret 3 has its spinneret nozzle higher than the upper surface of the guide plate 4, and the filament bundle 31 is stretched from the spinneret nozzle to the outlet 51. This design allows the spinneret position to be misaligned with the acid inlet, preventing the acid bath from interfering with the filament stretching process. This allows the filament to be stretched in a relatively stable space after being ejected from the spinneret 3. The spinneret nozzle of the spinneret 3 faces the outlet 51 and is wrapped in acid bath along the stretching path of the filament, avoiding unnecessary bending and twisting of the filament in the chamber 1.

[0028] During implementation, the guide plate 4 and the conical plate 5 are integrally connected. An upper limit cover 7 is installed on the upper end of the chamber body 1. The guide plate 4 and the conical plate 5 are installed on the chamber body 1 through the upper limit cover 7, and the conical plate 5 passes through the upper limit cover 7. The integrated design reduces the connection gaps and loosening possibilities between components. The upper limit cover 7 is threadedly connected to the upper end of the chamber body 1, and the annular guide plate 4 and the chamber body 1 are positioned and installed based on the step.

[0029] The guide plate 4 is integrally connected to the conical plate 5 and installed on the chamber 1 via the upper limit cap 7, while the adhesive tube 2 is installed inside the chamber 1 via the lower limit cap 8. This design enhances the overall integrity and stability of the structure, while also facilitating disassembly and assembly. The guide plate 4 is fixedly installed inside the chamber 1, with the horizontal section of the L-shaped guide plate 4 fixedly connected to the inner wall of the chamber 1.

[0030] The spinneret 3 has its nozzle higher than the upper surface of the guide plate 4. The adhesive filaments are drawn from the nozzle of the spinneret 3 to the outlet 51, with the nozzle of the spinneret 3 directly opposite the outlet 51. A sealing ring 9 is provided between the guide plate 4 and the chamber 1, positioned on the horizontal surface where they contact, and works in conjunction with the upper limit cap 7 for a sealed connection. A lower limit cap 8 is installed at the lower end of the chamber 1, and the adhesive tube 2 is mounted on the chamber 1 via the lower limit cap 8, with its lower end passing through the lower limit cap.

[0031] In implementation, the conical plate 5 is made of transparent material. When the conical plate 5 and the guide plate 4 are integrated, both the guide plate 4 and the conical plate 5 are made of transparent material. This allows operators to observe the flow state inside the chamber 1 and the forming of the adhesive filaments in real time during production. Operators can promptly detect and adjust any abnormalities, such as material blockage or filament breakage.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
