Description

Technical Field

[0001] This utility model relates to the field of viscose fiber production equipment, specifically a xanthation device for viscose fibers. Background Technology

[0002] Xanthation is a core chemical process in viscose fiber production. Its function is to react aged alkali cellulose with carbon disulfide to generate cellulose xanthate, which is then used to produce a spinnable viscose solution. Xanthation equipment uses agitators, temperature controllers, pressure gauges, and transmission systems to stir the viscose fibers after the xanthation reaction, so that they can form uniform spinning and high-quality finished products.

[0003] In existing xanthation devices, viscose fibers need to be discharged after use. However, viscose fibers are sticky, and after prolonged use, they can easily clog the outlet, affecting the speed and quantity of the viscose fibers flowing down, thus impacting the efficiency and lifespan of the xanthation device.

[0004] Therefore, this utility model proposes a xanthation device for viscose fibers to solve the above problems. Utility Model Content

[0020] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0021] Example 1: Please refer to Figures 1-4 This utility model provides a technical solution: a xanthation device for viscose fibers, the viscose fiber xanthation device includes: a storage tank 1, a stirring shell 2 installed on the top of the storage tank 1, a liquid outlet cylinder 3 installed at the bottom of the stirring shell 2, a hinge plate 4 installed at the bottom of the stirring shell 2, a sliding groove 5 opened at the bottom of the hinge plate 4, a rotating rod 6 installed through the inside of the sliding groove 5, the rotating rod 6 passing through the side wall of the liquid outlet cylinder 3, a push block 7 fixed on the outer surface of the rotating rod 6, and a drive motor 8 installed at the outer end of the rotating rod 6;

[0022] During use, viscose fiber is poured into the outlet cylinder 3. It undergoes xanthation and is stirred evenly by the clamping device inside the stirring housing 2. The drive motor 8 then rotates the rotating rod 6, which in turn rotates the pusher block 7. The uneven distribution of the pusher block 7 causes the longest end at the bottom to rotate to the top, maximizing the outflow of viscose fiber. Rotating to different surfaces allows for easy adjustment of the outflow. Under the action of the chute 5, the opening and closing plate 4 moves upward, allowing the xanthated viscose fiber to flow from the opening of the opening and closing plate 4 into the outlet cylinder 3 and then into the storage tank 1 for centralized collection. The lifting and lowering movement of the opening and closing plate 4 pushes the viscose fiber at the opening and carries it into the outlet cylinder 3, preventing the viscose fiber from clogging the liquid flow. This avoids the problem of existing xanthation devices requiring the discharge of viscose fiber after use. However, viscose fiber is sticky, and over time, it can easily clog the outlet, affecting the speed and quantity of the fiber flow and impacting the efficiency and lifespan of the xanthation equipment.

[0023] Example 2: Based on Example 1, a structure is provided to support and fix the rotating rod 6 and to prevent the top of the liquid outlet cylinder 3 from being blocked. The side wall of the rotating rod 6 is provided with a slot 9. A first bearing 10 is installed inside the slot 9. A plug rod 11 is installed at the center of the first bearing 10. A first polygonal plate 12 is installed on the outer surface of the plug rod 11. The plug rod 11 penetrates the side wall of the liquid outlet cylinder 3. A power motor 13 is installed at the outer end of the plug rod 11. A set of support frames 18 is installed on the top of the liquid storage tank 1. The set of support frames 18 is placed at the bottom of the drive motor 8 and the power motor 13 respectively.

[0024] In use, the side wall of the rotating rod 6 is connected and fixed inside the liquid outlet cylinder 3 via the first bearing 10 and the insert rod 11. Under the action of the first bearing 10, the power motor 13 drives the insert rod 11 to rotate, which in turn drives the first polygonal plate 12 to rotate. The first polygonal plate 12 uses multiple angled plates on its side wall to easily roll up the adhesive fibers, preventing the adhesive fibers from clogging the top of the liquid outlet cylinder. At the same time, under the action of centrifugal force and the angled surface of the polygonal plate, the adhesive fibers remaining on the surface of the polygonal plate flow out along the angled surface.

[0025] Example 3: Based on Example 2, a structure is provided to prevent blockage inside the liquid outlet cylinder 3. A second bearing 14 is installed on the inner wall of the liquid outlet cylinder 3. A connecting rod 15 is fixedly installed inside the second bearing 14. A set of second polygonal plates 16 are fixed on the outer surface of the connecting rod 15. The set of second polygonal plates 16 are placed parallel to each other. A third polygonal plate 17 is installed between the second polygonal plates 16. The first polygonal plate 12 and the second polygonal plate 16 are interlocked.

[0026] When in use, the first polygonal plate 12 rotates, which drives the second polygonal plate 16 to rotate through the meshing action of the angle plates. Under the action of the second bearing 14, the connecting rod 15 rotates, which in turn drives the third polygonal plate 17 to rotate synchronously, thereby stirring the inside of the liquid outlet cylinder 3 and preventing the adhesive fiber from clogging the liquid outlet pipe 3.

[0027] In actual use, viscose fiber is poured into the liquid outlet cylinder 3. After being xanthated and stirred evenly by the clamping device inside the stirring shell 2, the drive motor 8 drives the rotating rod 6 to rotate, which in turn drives the push block 7 to rotate. The uneven distribution of the push block 7 causes the longest end at the bottom to rotate to the top, which facilitates maximizing the outflow of viscose fiber. Rotating to different surfaces allows for easy adjustment of the outflow of viscose fiber. Under the action of the chute 5, the opening and closing plate 4 moves upward, allowing the xanthated viscose fiber to flow from the opening of the opening and closing plate 4 into the liquid outlet cylinder 3 and into the liquid storage tank 1 for centralized collection and treatment. The side wall of the rotating rod 6 is connected and fixed to the insertion rod 11 through the first bearing 10. The device is positioned inside the liquid outlet cylinder 3. Under the action of the first bearing 10, the power motor 13 drives the insertion rod 11 to rotate, which in turn drives the first polygonal plate 12 to rotate. Through the meshing action of the polygonal plates, the second polygonal plate 16 is driven to rotate. Under the action of the second bearing 14, the connecting rod 15 is driven to rotate, which in turn drives the third polygonal plate 17 to rotate synchronously. This stirs the inside of the liquid outlet cylinder 3, thus avoiding the need to discharge the viscose fiber after the existing xanthation device is used. However, viscose fiber is sticky, and after a long period of use, it is easy for the viscose to block the liquid outlet, affecting the speed and quantity of viscose fiber flowing down, and also affecting the efficiency and service life of the xanthation equipment.
