Description

Technical Field

[0001] This application relates to the field of polyvinyl alcohol fibers, and more specifically, to an apparatus for low-temperature water washing of polyvinyl alcohol fibers. Background Technology

[0002] Polyvinyl alcohol (PVA) fiber is widely used in textiles, papermaking, and construction due to its excellent properties (such as high strength, good tensile strength, and strong abrasion resistance). However, traditional washing methods usually require high temperatures, which not only increases energy consumption but may also affect the fiber properties. Therefore, developing a low-temperature washing method is of great significance for improving the application value of PVA fiber.

[0003] Patent document CN211142247U discloses a device for low-temperature washing of polyvinyl alcohol (PVA) fibers, comprising: an electrolytic cell, positive electrode plates and negative electrode plates disposed on both sides of the electrolytic cell, a position through which the PVA fibers pass between the positive and negative electrode plates, reaction waste outlets disposed on both sides of the electrolytic cell, and an air outlet disposed at the upper end of the electrolytic cell. This utility model, by setting the washing tank as an electrolytic cell, discharges the PVA fiber residue through electrolysis and hydrolysis reactions via the air outlet and reaction waste outlet. It requires low temperatures, resulting in a high PVA fiber production conversion rate. While the aforementioned application also demonstrates high PVA fiber production conversion rate due to the discharge of residues through electrolysis and hydrolysis reactions via the air outlet and reaction waste outlet, the height of the electrolytic cell is fixed during use, making it difficult for operators of different heights to effectively observe the washing effect of the PVA fibers. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a device for low-temperature washing of polyvinyl alcohol fibers, solving the problems mentioned in the background section. To achieve the above objectives, this utility model is implemented through the following technical solution: A device for low-temperature washing of polyvinyl alcohol fibers includes a base, on which an adjusting device is provided. The adjusting device includes a fixing block, which is fixedly connected to the top of the base. A slider is slidably connected to the inner wall of the fixing block. A movable rod is hinged to the front of the slider, and a first connecting plate is hinged to the back of the movable rod. An electrolytic cell is fixedly connected to the top of the first connecting plate. A bracket is fixedly connected to the top of the slider, and a connecting block is fixedly connected to the top of the bracket. An auxiliary rod is hinged to the back of the movable rod, and a second connecting plate is hinged to the front of the auxiliary rod. The second connecting plate is fixedly connected to the top of the base.

[0005] Preferably, a lead screw is rotatably connected to the left side of the fixing block via a bearing, and the connecting block is threadedly connected to the outer wall of the lead screw.

[0006] Preferably, a dual-head motor is fixedly connected to the bottom of the electrolytic cell via a connecting rod, the lead screw extends to the right through the fixed block, and the extended end of the lead screw is fixedly connected to the output end of the dual-head motor.

[0007] Preferably, the base is provided with a rotating device, the rotating device including a rack, the rack being fixedly connected to the top of the base, and a rotating rod being rotatably connected to the front of the inner wall of the electrolytic cell via a bearing, the rotating rod having a fan blade fixedly connected to its front.

[0008] Preferably, the rotating rod extends movably through the electrolytic cell to the back side, a circular gear is fixedly sleeved on the outer wall of the rotating rod, and a sealing gasket is provided at the connection between the rotating rod and the electrolytic cell.

[0009] Preferably, the sprocket and the rack mesh with each other.

[0010] The advantages of this application are:

[0011] I. This application, by setting up an adjustment device, starts a double-headed motor, which drives the lead screw to rotate. The lead screw drives the connecting block to move to the left, the connecting block drives the support to move to the right, the support drives the slider to move to the left, the slider drives the movable rod to move to the right, and the movable rod, through the constraint of the auxiliary rod, moves the electrolytic cell to the bottom. Operators of different heights can adjust the position of the electrolytic cell according to their own height, improving the convenience of operation. This solves the problem in the background technology that the height of the electrolytic cell is fixed during use, making it difficult for operators of different heights to observe the washing effect of polyvinyl alcohol fibers.

[0012] Second, this application uses a rotating device. The electrolytic cell descends, causing the circular gear to slide against the inner wall of the rack. The rotation of the circular gear causes the rotating rod to rotate, which in turn causes the fan blades to rotate. The rotation of the fan blades causes the water to generate eddies and flow within the electrolytic cell. This allows the cleaning solution to fully contact the surface of the polyvinyl alcohol fiber. The generation of eddies allows the cleaning solution to more comprehensively contact the surface of the polyvinyl alcohol fiber, increasing the effective area of ​​the cleaning solution and thus improving the cleaning effect.

[0021] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments. Example 1

[0022] See Figures 1-4This embodiment provides a device for low-temperature washing of polyvinyl alcohol fibers, including a base 1. An adjustment device 2 is mounted on the base 1. The adjustment device 2 includes a fixing block 21 fixedly connected to the top of the base 1. A slider 22 is slidably connected to the inner wall of the fixing block 21. A movable rod 26 is hinged to the front of the slider 22, and a first connecting plate 210 is hinged to the back of the movable rod 26. An electrolytic cell 27 is fixedly connected to the top of the first connecting plate 210. A bracket 23 is fixedly connected to the top of the slider 22, and a connecting block 24 is fixedly connected to the top of the bracket 23. An auxiliary rod 28 is hinged to the back of the movable rod 26, and a second connecting plate 211 is hinged to the front of the auxiliary rod 28. The second connecting plate 211 is fixedly connected to the top of the base 1. The base 1 serves as the supporting structure for the entire device, ensuring its stability and safety. The adjustment device 2 is the core component of this device, allowing users to adjust the device's operating state according to different operational needs. The fixing block 21 provides a stable support point, enabling the slider 22 to slide smoothly, thereby adjusting the position of the movable rod 26. Electrolytic cell 27 is located on top of the first connecting plate 210 and is responsible for carrying out the necessary electrolytic reaction to improve the efficiency of the washing process. Support 23 and connecting block 24 ensure the connection and support of the entire system, providing good mechanical strength. A lead screw 25 is rotatably connected to the left side of the fixing block 21 via a bearing, and the connecting block 24 is threaded onto the outer wall of the lead screw 25. A dual-head motor 29 is fixedly connected to the bottom of the electrolytic cell 27 via a connecting rod. The lead screw 25 extends to the right side through the fixing block 21, and the extended end of the lead screw 25 is fixedly connected to the output end of the dual-head motor 29.

[0023] When the above equipment is used, the dual-head motor 29 is started, which drives the lead screw 25 to rotate. The lead screw 25 drives the connecting block 24 to move to the left. The connecting block 24 drives the bracket 23 to move to the right. The bracket 23 drives the slider 22 to move to the left. The slider 22 drives the movable rod 26 to move to the right. The movable rod 26, through the restriction of the auxiliary rod 28, causes the electrolytic cell 27 to move to the bottom. Example 2

[0024] See Figures 1-4Based on Embodiment 1, a rotating device 3 is provided on the base 1. The rotating device 3 includes a rack 31, which is fixedly connected to the top of the base 1. A rotating rod 32 is rotatably connected to the front of the inner wall of the electrolytic cell 27 via a bearing. A fan blade 34 is fixedly connected to the front of the rotating rod 32. Its main function is to provide dynamic liquid flow, which helps to achieve a more uniform washing effect in the electrolytic cell 27. The connection design between the rack 31 and the rotating rod 32 of the electrolytic cell allows the fan blade 34 to generate flow inside the electrolytic cell through the drive of the rotating device, thereby enhancing the washing effect of the liquid on the polyvinyl alcohol fibers. This structural design effectively improves the washing efficiency of the entire device, making it adaptable to different washing requirements. The rotating rod 32 extends movably through the electrolytic cell 27 to the back. A circular gear 33 is fixedly sleeved on the outer wall of the rotating rod 32. A sealing gasket is provided at the connection between the rotating rod 32 and the electrolytic cell 27. The circular gear 33 meshes with the rack 31.

[0025] When the above equipment is used, the electrolytic cell 27 descends, causing the spur gear 33 to slide on the inner wall of the rack 31. The rotation of the spur gear 33 causes the rotating rod 32 to rotate, which in turn causes the fan blade 34 to rotate. The rotation of the fan blade 34 causes the water to generate eddies and flow in the electrolytic cell 27, allowing the cleaning solution to fully contact the surface of the polyvinyl alcohol fiber.

[0026] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
