Description

Technical Field

[0001] This utility model relates to the field of ultrafiltration membrane production technology, specifically to a drying rack for rapidly drying membrane fibers. Background Technology

[0002] Hollow fiber membranes can be prepared using various methods, including wet spinning, dry-wet spinning, melt spinning, and dry spinning. The dry-wet spinning method is currently the most widely used. The dry-wet spinning process involves dissolving polymer materials and additives in a solvent, followed by a coagulation bath (where the solvent and water are mixed in a specific ratio) to obtain hollow fiber membranes with a specific pore structure. The nascent membranes need to be soaked and washed to remove residual solvent, release excess stress, and reduce shrinkage during subsequent drying. After soaking and washing, the membranes require further drying to obtain the finished membrane.

[0003] The degree of dryness of the membrane fibers significantly affects the cycle time of the membrane fiber production section and the module casting section. Existing ultrafiltration membrane fiber drying processes typically involve directly hanging the soaked and washed membrane fibers onto a drying rack and transferring them to a drying room for air drying, or adding drying equipment to the production line for drying, thus increasing the production line length. Therefore, this invention provides a low-cost, simple-to-operate and maintain multi-functional drying rack that can quickly dry membrane fibers while saving labor, and is suitable for drying membrane fibers of different lengths. Summary of the Invention

[0004] Technical problem: The technical problem to be solved by this utility model is to provide a drying rack for rapidly drying film filaments, which is suitable for rapidly drying film filaments of different lengths, saving manpower, improving production efficiency, and at the same time, allowing for solvent recovery.

[0005] Technical solution: To solve the above technical problems, the technical solution adopted in this utility model embodiment is as follows: a drying rack for quickly drying film filaments, comprising: a support, a support rod, a drying rod, and a hook. The support rod is located on the support, and the drying rod is provided on the support rod. The drying rod is hollow and tubular, and has a ventilation opening. The drying rod is connected to an air source, and has a hook.

[0006] Furthermore, the hook is equipped with a baffle, both the baffle and the hook are located below the vent and are fixedly connected to the drying rod by an elastic element. When there is no film thread hanging on the hook, the baffle can seal the vent. When the film thread is hanging on the hook, the baffle separates from the vent to allow ventilation.

[0007] Furthermore, the baffle is umbrella-shaped to seal the vent when there is no membrane fiber bundle suspended, and when there is a membrane fiber bundle suspended, the air output from the vent can be transmitted downward along the baffle.

[0008] Furthermore, the support is equipped with rollers at the bottom, allowing the drying rack to be moved as needed.

[0009] Furthermore, the support rod is equipped with a ventilation device to accelerate the drying of the membrane fiber bundle.

[0010] Furthermore, the ventilation device is a fan, and the angle of the fan is adjustable.

[0011] Furthermore, the support is provided with a collection groove for collecting the liquid dripping from the film filament bundles during the initial drying stage.

[0012] Beneficial Effects: Compared with the prior art, the technical solution of this utility model has the following beneficial effects: By setting ventilation openings on the drying rod, this utility model can blow air from top to bottom onto the film filament bundles suspended under the drying rod, accelerating the drying of the film filaments while avoiding blowing them into disarray, preventing the film filaments from becoming disordered or uneven. A baffle is provided between the hook and the ventilation opening, and the hook is connected to the drying rod through an elastic element, so that the corresponding ventilation opening will only open when film filaments are suspended on the hook, thus avoiding wasting air and saving energy. Setting ventilation openings on the drying rod does not require adding a separate ventilation component, resulting in a simple structure. At the same time, a ventilation device can be set on the support rod, and the angle is adjustable, allowing air to be blown onto different positions of the film filaments, ensuring uniform drying, improving the drying efficiency of the film filaments, and meeting the needs of modern production.

[0020] The technical solution of this utility model will now be described in detail with reference to the accompanying drawings.

[0021] according to Figure 1-6 A drying rack for quickly drying film fibers includes: a support 1, which supports a support rod 3 and a drying rod 4, and a pulley 10 can be installed under the support 1 to facilitate the movement of the drying rack;

[0022] Support rod 3 is used to support and fix the drying rod 4. The support rod 3 is located on the support 1. A ventilation device 2 can also be installed on the support rod. The angle of the ventilation device 2 is adjustable, so that the film bundles 6 located on both sides of the ventilation device 2 can be dried by blowing air at different positions, so that the drying is uniform. The ventilation device 2 can be a blower or a ventilation rod with ventilation openings.

[0023] The drying rod 4 is a hollow tube with a ventilation opening 11. The drying rod 4 is connected to an air source and has a hook 5.

[0024] The aforementioned drying rack for rapidly drying film fibers comes in various forms, such as... Figure 1 and Figure 5 These are two different types of wire drying racks. Figure 5 In the process, the drying rod 4 is connected to the air inlet pipe 13, and the air inlet pipe 13 is provided with an air inlet 12 to provide an air source for the drying rack 4.

[0025] In one embodiment, the drying rod 4 is provided with multiple rows of ventilation openings along the direction of the drying rod. After the drying rod 5 is connected to the ventilation device, the film bundles 6 below and on both sides of the drying rod 4 can be ventilated and dried.

[0026] In one embodiment, the hook 5 is positioned below the vent 11, with each hook 5 corresponding to a vent 11. A baffle 8 is provided between the hook 5 and the vent 11, and the hook 5 is connected to the drying rod 4 via an elastic element 7. When the hook 5 suspends the film filament bundle 6, the baffle 8 separates from the vent 11 under the action of gravity, allowing air to blow and dry the film filament bundle. When the hook 5 does not suspend the film filament bundle 6, the baffle 8 closes with the vent 11 under the action of the elastic element, and the vent corresponding to that hook does not ventilate. This design allows for individual control of the through-hole corresponding to the hook. Ventilation is only allowed when the hook 5 suspends the film filament bundle, avoiding waste of air source due to collective ventilation when the drying rod has a small number of film filament bundles, and further reducing energy consumption.

[0027] Preferably, the baffle is umbrella-shaped to seal the vent when there is no membrane fiber bundle suspended, and when there is a membrane fiber bundle suspended, the air output from the vent can be transmitted downward along the baffle, thereby expanding the ventilation area.

[0028] Furthermore, the support is equipped with rollers at the bottom, allowing the drying rack to be moved as needed.

[0029] Furthermore, the support rod is equipped with a ventilation device, which can be a fan or a ventilation rod with ventilation openings around it, to further accelerate the drying of the membrane fiber bundle and shorten the drying time of the membrane fiber.

[0030] Furthermore, the ventilation device is a fan, and the angle of the fan is adjustable, which can blow air to different positions of the membrane fiber bundle to make the drying more uniform.

[0031] Furthermore, the support is equipped with a collection groove to collect the liquid dripping from the film filament bundles during the initial drying stage, thus preventing ground contamination.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the specific embodiments described above. The specific embodiments and descriptions in the specification are merely for further illustrating the principles of this utility model.
