Description

Technical Field

[0001] This utility model relates to the field of viscose filament production technology, and in particular to an acid filament separator and a vertical spinning system using the acid filament separator. Background Technology

[0002] In the production of viscose filaments, the viscose solution is sprayed out from the nozzle in the reaction chamber and reacted and formed in the filament forming tube to become a continuous filament. In this spinning system, the acid bath in the forming tube flows with the filament and flows outward. At this time, the filament is coated with a layer of acid. This attached acid not only affects the subsequent processing performance of the filament, but also drips and splashes along the filament traction direction. Therefore, it is necessary to separate the acid from the filament.

[0003] When using an acid scraper to separate acid, the process primarily relies on the contact between the scraper's surface and the filament surface. As the filament passes the scraper, the scraper uses friction to scrape off the acid from the filament's surface. This method is limited by factors such as the size and surface condition of the scraper, as well as the filament's traction speed. During the scraping process, the scraped acid may re-adhere to the filament or flow along it, requiring continuous cleaning of the scraper's surface and collection of the acid, which also affects the overall separation efficiency.

[0004] Therefore, there is a need for an acid separator that can be applied to spinning systems, especially in vertical spinning systems, to separate most of the acid from the filaments and ensure that the filaments enter the subsequent processes in a relatively "pure" state. Utility Model Content

[0005] To address the shortcomings of the prior art, this utility model provides an acid fiber separator and a vertical spinning system using the acid fiber separator.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an acid fiber separator, the acid fiber separator includes an inner shell, the bottom of the inner shell has a fiber inlet hole, the periphery of the inner shell is provided with a plurality of acid outlet holes, the upper end of the inner shell is covered with an inner cover plate, the inner cover plate has a separation hole in the middle, the fiber passes through the inner shell and the inner cover plate through the fiber inlet hole and the separation hole, and the separation hole is used to separate the acid liquid on the fiber.

[0007] Furthermore, it also includes an outer shell, the inner shell being located inside the area enclosed by the outer shell, and there is an annular space between the inner shell and the outer shell, the acid outlet being connected to the inner shell and the annular space. Furthermore, the outer cover plate is provided on the upper end of the outer shell, and the outer cover plate has a wire outlet hole in the middle. The inner cover plate is provided with an overflow hole on the periphery of the separation hole, and the overflow hole is connected to the annular space.

[0008] Furthermore, the inner cover plate is rotatably mounted on the inner housing, and the separation hole is eccentrically located on the inner cover plate.

[0009] Furthermore, the outer edge of the bottom of the inner shell extends axially downward to form a buffer zone.

[0010] Furthermore, the diameter of the inner shell gradually decreases axially from the bottom towards the inner cover plate.

[0011] Furthermore, the outer shell, inner shell, outer cover plate, and inner cover plate are provided with longitudinal slots on their periphery.

[0012] Furthermore, the wire inlet hole, separation hole, and wire outlet hole are embedded with a ceramic separation layer.

[0013] A vertical spinning system employing the aforementioned acid filament separator includes a reaction chamber, a forming tube, and a guide wheel arranged vertically. The forming tube is vertically connected to the upper outlet of the reaction chamber. The acid filament separator and the guide wheel are installed above the forming tube. The viscose filaments in the reaction chamber pass through the upper end of the reaction chamber and extend vertically, passing through the forming tube and the acid filament separator in sequence, then around the guide wheel and introduced into the processing roller.

[0014] Furthermore, the reaction chamber includes 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, converging towards the axis of the chamber body, is provided at the top of the chamber body. The upper end of the conical plate has a filament outlet, forming a laminar flow reaction zone between the filament 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 into the laminar flow reaction zone through the outlet formed by the lower edge of the guide plate and the chamber body.

[0015] In summary, this utility model has the following beneficial effects: (1) The acid separator separates the acid liquid on the filament through the inner cover plate on the inner shell and the separation hole on the inner cover plate. The separated acid liquid is trapped in the area between the inner cover plate and the bottom of the inner shell and is discharged out of the inner shell through the acid outlet hole. The filament passes through the inlet hole and the separation hole in sequence. When the spinning system is in acid bath, the inner shell can separate most of the acid liquid from the filament, and the inner cover plate further separates the acid liquid wrapped on the filament.

[0016] (2) The acid filament separator includes an outer shell and an inner shell. There is an annular space between the inner shell and the outer shell. The acid filament separator separates the acid liquid on the filament formed by the reaction chamber and blocks the impact of the acid liquid in the vertical forming tube. The separated acid liquid enters the annular space and is guided out in an orderly manner to avoid splashing.

[0017] (3) The vertical spinning system can change the forming direction of viscose filaments, utilize vertical space, reduce the floor area, and simplify the acid bath circulation path. The filaments are guided to the treatment rollers through the vertical spinneret in the reaction chamber and formed into continuous filaments in the acid bath in the vertically set reaction chamber. The direction of the acid bath spray is always consistent with the direction of the filaments sprayed from the spinneret in the reaction chamber, so that the filaments can be uniformly acid bathed, so as to ensure the filaments are formed in the vertical space.

[0024] The present invention will be further described in detail below with reference to the embodiments.

[0025] Example 1 like Figures 1 to 3As shown, an acid fiber separator 3 includes an inner shell 32. The bottom of the inner shell 32 has a fiber inlet hole 3222. The inner shell 32 has a plurality of acid outlet holes 321 on its periphery. The upper end of the inner shell 32 is covered with an inner cover plate 322. A separation hole 3221 is opened in the middle of the inner cover plate 322. The fiber passes through the inner shell 32 and the inner cover plate 322 through the fiber inlet hole 3222 and the separation hole 3221. The separation hole 3221 is used to separate the acid liquid on the fiber.

[0026] The wire inlet hole 3222 at the bottom of the inner shell 32 and the separation hole 3221 in the middle of the inner cover plate 322 cooperate with each other to form a channel specifically for the wire, so that the acid can be effectively intercepted and separated at the separation hole 3221 during the process of the wire passing through the inner shell 32 and the inner cover plate 322.

[0027] Multiple acid outlet holes 321 are provided around the inner shell 32, ensuring that the acid can be quickly discharged from multiple directions once it is detached from the filament. This effectively avoids acid accumulation inside the shell, reduces the risk of secondary contamination of the filament by the acid, and also makes acid recovery or subsequent treatment more convenient, optimizing the acid treatment process of the entire production environment.

[0028] Example 2 like Figures 1 to 3 As shown, based on an acid fiber separator in Embodiment 1, the acid fiber separator 3 includes an inner shell 32 and an outer shell 31. The bottom of the inner shell 32 has a fiber inlet hole 3222, and the periphery of the inner shell 32 is provided with multiple acid outlet holes 321. The upper end of the inner shell 32 is covered with an inner cover plate 322, and a separation hole 3221 is opened in the middle of the inner cover plate 322. The fiber passes through the inner shell 32 and the inner cover plate 322 through the fiber inlet hole 3222 and the separation hole 3221. The separation hole 3221 is used to separate the acid liquid on the fiber. The inner shell 32 is located inside the area enclosed by the outer shell 31, and there is an annular space 33 between the inner shell 32 and the outer shell 31. The acid outlet holes 321 connect the inner shell 32 and the annular space 33. The outer cover plate 311 is provided on the upper end of the outer cover plate 311. The outer cover plate 311 has a wire outlet hole 3111 in the middle. The inner cover plate 322 is provided with an overflow hole 3223 on the periphery of the separation hole 3221. The overflow hole 3223 is connected to the annular space 33.

[0029] The inner cover plate 322 is rotatably mounted on the inner housing 32, and the separation hole 3221 is eccentrically positioned on the inner cover plate 322. The outer housing 31, inner housing 32, outer cover plate 311, and inner cover plate 322 have longitudinally spaced slots 35 on their periphery. These longitudinal slots 35 facilitate the insertion of the filament into the acid filament separator 3, i.e., into the inner housing 32, allowing the filament to pass sequentially from bottom to top through the inlet hole 3222, the separation hole 3221, and the outlet hole 3111. The inner cover plate 322 on the inner housing 32 is rotatably connected to the inner housing 32, and the separation hole 3221 is eccentrically positioned on the inner cover plate 322. The outlet hole 17 and the inlet hole 3222 can be coaxially aligned. By rotating the inner cover plate 322, the relative position of the separation hole 3221 can be adjusted, thereby regulating the amount of acid scraped.

[0030] The acid fiber separator 3 adopts a double-layer structure of outer shell 31 and inner shell 32. The annular space 33 between the inner shell 32 and the outer shell 31, as well as the fiber inlet hole 3222 and acid outlet hole 321 on the inner shell 32, can efficiently separate the acid liquid on the fiber, ensuring the quality of the fiber and the smooth progress of subsequent processing.

[0031] The annular space 33 between the inner shell 32 and the outer shell 31 provides a dedicated area for the collection and temporary storage of acid. When the filament enters through the inlet hole 3222 at the bottom of the inner shell 32, the acid adhering to the filament will flow rapidly into the annular space 33 through the acid outlet hole 321 on the periphery under the combined action of centrifugal force and gravity as the filament passes through the inner shell 32. This achieves preliminary and efficient separation of acid from the filament, effectively avoiding acid residue on the filament and greatly improving acid separation efficiency.

[0032] After the filament passes through the separation hole 3221, the acid on the filament is separated by the separation hole 3221. At the same time, the inner cover plate 322 is provided with an overflow hole 3223 on the periphery of the separation hole 3221. The acid separated by the separation hole 3221 flows into the annular space 33 through the overflow hole 3223. In practice, the acid in the annular space 33 can be directionally discharged through the connecting acid discharge pipe 7.

[0033] Example 3 From a space utilization perspective, the horizontally placed filament forming tubes and their associated acid bath circulation system occupy a significant amount of workshop space, limiting further expansion of production scale and hindering compact equipment layout and flexible adjustments. This results in lengthy material handling paths within the workshop, increasing production time and costs. Regarding production process optimization, the transversely flowing acid bath makes it difficult to achieve uniform and precise flow rate control, especially in long horizontal tube sections. This can easily lead to gradient differences in acid bath concentration and temperature, affecting the consistency of filament forming quality, increasing the defect rate, and complicating subsequent processing.

[0034] To significantly improve the space utilization of the production workshop, achieve an efficient and compact layout of equipment, and ensure a uniform and stable supply of acid bath during the filament forming process, more precise control of acid bath flow and filament forming conditions is required. Figure 4 and Figure 5 As shown, this embodiment provides a vertical spinning system using an acid filament separator 3, including at least one viscose filament forming line, a reaction chamber 1, a forming tube 2, an acid filament separator 3, and a guide wheel 4 arranged vertically. The forming tube 2 is vertically connected to the upper outlet of the reaction chamber 1, and the acid filament separator 3 is fixedly installed at the upper end of the forming tube 2. The guide wheel 4 is located directly above the acid filament separator 3. The viscose filament in the reaction chamber 1 passes through the upper end of the reaction chamber 1 and extends vertically, passing through the forming tube 2 and the acid filament separator 3 in sequence, and then passes around the guide wheel 4 and is guided to the processing roller 6. The guide wheel 4 guides the direction of the viscose filament into the processing roller 6.

[0035] Because the viscose stream flows vertically upwards, and the acid bath also flows vertically, the impact of the acid bath on the filament is smaller. This allows for increased spinning speed while ensuring the quality of the acid bath and filament formation. Therefore, the rational configuration of elements such as the vertical layout, acid-filament separator 3, and guide roller 4 helps to optimize the fiber morphology and production process.

[0036] By arranging the fibers vertically and controlling the filament forming shape of the viscose filaments using the filament output direction of reaction chamber 1, the filaments in the acid bath of reaction chamber 1 form a 90° angle with the horizontal direction, which enables the fiber forming process in the vertical direction.

[0037] The acid-fiber separator 3 includes an outer shell 31 and an inner shell 32. The inner shell 32 is located inside the area enclosed by the outer shell 31, and there is an annular space 33 between the inner shell 32 and the outer shell 31. The bottom of the inner shell 32 has a fiber inlet hole 3222, and the periphery of the inner shell 32 is provided with multiple acid outlet holes 321, which connect the inner shell 32 and the annular space 33. The double-layer structure of the outer shell 31 and the inner shell 32, the annular space 33 between the inner shell 32 and the outer shell 31, and the design of the fiber inlet hole 3222 and the acid outlet hole 321 on the inner shell 32 can efficiently separate the acid from the fiber, ensuring the quality of the fiber and the smooth progress of subsequent processing.

[0038] The inner shell 32 is covered with an inner cover plate 322, and a separation hole 3221 is formed in the middle of the inner cover plate 322. The outer shell 31 is covered with an outer cover plate 311, and a wire outlet hole 3111 is formed in the middle of the outer cover plate 311. After the wire passes through the separation hole 3221, the acid on the wire is separated by the separation hole 3221. At the same time, the inner cover plate 322 is provided with an overflow hole 3223 on the periphery of the separation hole 3221. The acid separated by the separation hole 3221 flows into the annular space 33 through the overflow hole 3223. In practice, the acid in the annular space 33 can be discharged through the connecting acid drain pipe 7.

[0039] The inner cover plate 322 is rotatably mounted on the inner housing 32, and the separation hole 3221 is eccentrically positioned on the inner cover plate 322. The outer housing 31, inner housing 32, outer cover plate 311, and inner cover plate 322 have longitudinally spaced slots 35 on their periphery. These longitudinal slots 35 facilitate the insertion of the filament into the acid filament separator 3, i.e., into the inner housing 32, allowing the filament to pass sequentially from bottom to top through the inlet hole 3222, the separation hole 3221, and the outlet hole 3111. The inner cover plate 322 on the inner housing 32 is rotatably connected to the inner housing 32, and the separation hole 3221 is eccentrically positioned on the inner cover plate 322. The outlet hole 17 and the inlet hole 3222 can be coaxially aligned. By rotating the inner cover plate 322, the relative position of the separation hole 3221 can be adjusted, thereby regulating the amount of acid scraped.

[0040] Example 4 like Figure 4 and Figure 5 As shown, a vertical spinning system based on an acid filament separator 3 in Embodiment 3 includes at least one viscose filament forming line, a reaction chamber 1, a forming tube 2, an acid filament separator 3, and a guide wheel 4 arranged vertically. The forming tube 2 is vertically connected to the upper outlet of the reaction chamber 1. The acid filament separator 3 is fixedly installed at the upper end of the forming tube 2. The guide wheel 4 is located directly above the acid filament separator 3. The viscose filament in the reaction chamber 1 passes through the upper end of the reaction chamber 1 and extends vertically, passing through the forming tube 2 and the acid filament separator 3 in sequence, and then passes around the guide wheel 4 and is guided to the processing roller 6. The guide wheel 4 guides the direction of the viscose filament into the processing roller 6.

[0041] The inner shell 32 is movably installed within the outer shell 31, and the diameter of the inner shell 32 gradually decreases axially from the bottom towards the inner cover plate 322. This allows the acid outlet 321 on the inner shell 32, near the inner cover plate 322, to discharge the separated acid solution into the annular space 33 first. Preferably, an acid discharge pipe 7 connected to the annular space 33 can be installed in the outer shell 31 to discharge the acid solution within the annular space 33.

[0042] The bottom outer edge of the inner shell 32 extends axially downward to form a buffer zone 34. The periphery of the acid separator 3 extends vertically downward to form a brim. The annular brim extends downward for a certain length. After the acid separator 3 prevents the acid bath from being sprayed out of the forming tube 2, the brim prevents the acid bath from splashing out.

[0043] like Figure 6 The reaction chamber 1 includes a chamber body 11 and an adhesive tube 12 disposed within the chamber body 11. An acid inlet channel 13 is provided on the side of the chamber body 11, and an adhesive inlet channel 14 is provided at the bottom of the chamber body 11. An annular guide plate 15 is provided inside the chamber body 11, with a gap between the guide plate 15 and the inner wall of the chamber body 11. A conical plate 16, converging towards the axis of the chamber body 11, is provided at the top of the chamber body 11. The upper end of the conical plate 16 has a filament outlet 17. A laminar flow reaction zone 18 is formed between the bottom of the conical plate 16 and the adhesive tube 12. The adhesive tube 12 extends into the laminar flow reaction zone 18 and is equipped with a spinneret 19. The lower edge of the guide plate 15 extends downward into or beyond the acid inlet channel 13 to buffer the impact force of the acid bath. The guide plate 15 surrounds the outside of the spinneret 19. The acid liquid is input into the chamber 11 through the acid inlet channel 13 and flows to the laminar flow reaction zone 18 through the outlet position formed by the lower edge of the guide plate 15 and the chamber 11.

[0044] In the above embodiments, preferably, the wire inlet hole 3222, the separation hole 3221 and the wire outlet hole 3111 are embedded with a ceramic separation layer. The ceramic separation layer is made of a smooth material, which can avoid damage to the wire when separating acid liquid.

[0045] By using a vertical arrangement, the viscose filament forming shape is controlled by forming tube 2 and reaction chamber 1. Forming tube 2 extends into reaction chamber 1 at a 90° angle to the horizontal direction, which enables the fiber to be formed in the vertical direction. The viscose solution is sprayed directly onto forming tube 2 through spinneret 19 in reaction chamber 1, and further formed in the acid bath inside forming tube 2. The acid filament separator 3 helps to prevent the acid bath from interfering with the viscose filament and ensures the stability of the forming process.

[0046] 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.
