Description

Technical Field

[0001] The utility model relates to the technical field of hollow fiber membranes, in particular to a hollow fiber membrane magnetic active device. Background Art

[0002] Hollow fiber membrane refers to a self-supporting membrane with a fiber-like appearance. Hollow fiber membrane is made of polysulfone and dimethylacetamide as raw materials to form a fiber with a hollow inner cavity, and then divided by a high permeability polymer. It has selective permeability characteristics. When processing hollow fiber membranes, it needs to be further processed by active devices, such as:

[0003] Announcement No. CN114471182B provides a high-precision integrated hollow fiber membrane spinning device and its production process, including an isolation cabin, wherein the inner ends of the isolation cabin are respectively provided with a spinning mechanism and a membrane pressing mechanism, and the outer side of the isolation cabin is provided with a raw material processing mechanism. The present invention realizes that the surface of the guide needle has a certain magnetism by utilizing the principle of electromagnetic induction, so that when the raw material fiber flows in the forming cavity, the spinning fibers contained therein are all adsorbed by the guide needle and evenly wrapped on the outer wall of the guide needle. In conjunction with the high-speed nitrogen flow introduced, because the output ends of the two air holes are arranged in a staggered manner front and back, the air flow will generate a vortex blowing toward the front side in the forming cavity, so that the spinning fibers can be quickly spirally wound around the outer wall of the guide needle. The continuously wound spinning fibers will squeeze out the gas in the hollow fiber, which not only speeds up the speed of spinning and cooling into silk, but also prevents the formation of bubble structures in the produced hollow fiber, greatly improving the structural strength of the hollow fiber.

[0004] The above-mentioned existing technical solutions have the following defects: since the existing hollow fiber membrane spinning system is a follow-up system, the hollow fiber membrane is subjected to uneven force during the spinning process, resulting in unstable spinning and easy wire breakage, and the membrane wire shakes a lot during the spinning process, which easily causes membrane wire quality problems. Therefore, the utility model provides a hollow fiber membrane magnetic active device to solve the above-mentioned problems. Utility Model Content

[0014] By adopting the above scheme, the existing silk-out system is a follow-up system, so the hollow fiber membrane is subjected to uneven force during the spinning process, resulting in unstable silk-out and easy breakage of the silk. In addition, the membrane silk shakes a lot during the silk-out process, which easily causes membrane silk quality problems. When moving up and down through the lifting platform, the track support wheel frame can move up and down stably at the outer end of the guide track to prevent shaking during movement from affecting the silk-out.

[0015] As a preferred technical solution of the present invention, a limit rod is provided on the upper side of the right end of the lifting platform, and limit comb teeth are installed at equal intervals on the outer end of the limit rod.

[0017] As an optimal technical solution of the present invention, the guide wheel fixed base also includes a magnetic coupling arranged at the right end of the guide wheel fixed base, and a reducer is installed at the right end of the magnetic coupling, and the rear end of the reducer is connected to a servo motor by bolts.

[0018] The above solution adopts the setting of magnetic coupling to solve the problem of difficult transmission due to the insulation layer of the water tank.

[0019] As a preferred technical solution of the present invention, hinged movable rails are provided inside the guide rail, and the hinged movable rails are arranged at equal intervals inside the guide rail to play a role in stable movement.

The servo motor is used to accurately control the speed to provide power to the membrane wire, ensuring stable wire drawing without shaking.

[0021] As a preferred technical solution of the present invention, the right end of the magnetic coupling is provided with a bolt hole through a block structure to achieve a stable installation.

[0022] By adopting the above scheme, the guide wheel fixed base and the use of magnetic coupling are adopted, and the lifting platform is reinforced and stabilized, so that the limit rod is changed from the original follower guide wheel to the current active guide wheel, and the output force is kept stable under the precise control of the servo motor.

[0025] 2. The guide wheel connector is used to move up and down through the guide track and the track wheel, so that it can be used in multiple directions. The existing spinning system is a follow-up system, so the hollow fiber membrane is unevenly stressed during the spinning process, resulting in unstable and easy broken wires. In addition, the membrane shakes a lot during the spinning process, which can easily cause membrane quality problems. When the lifting platform moves up and down, the track support wheel frame can move up and down stably at the outer end of the guide track to prevent shaking during movement that affects the spinning;

[0026] 3. The servo motor is connected to the rear end of the reducer by bolts, and the magnetic coupling is used to solve the problem of difficult transmission due to the insulation layer of the water tank. A hinged movable rail is provided inside the guide track, and the hinged movable rail is arranged at equal intervals inside the guide track to play a role in stable movement, starting and controlling the precise output of the servo motor, thereby preventing the problem of wire breakage caused by unstable output force, and speeding up the wire drawing speed, improving production efficiency.
