Description

Technical Field

[0001] This invention relates to the field of ultrafiltration membrane fiber drying technology, specifically to an anti-deformation and uniform air distribution structure for drying ultrafiltration membrane fibers. Background Technology

[0002] Ultrafiltration membrane fibers are polymer semi-permeable membrane modules composed of multiple membrane fibers. During their assembly and preparation, ultrafiltration membrane fibers are usually first soaked in a humectant and then air-dried. Here, air-drying specifically refers to mechanical air-drying of ultrafiltration membrane fibers.

[0003] The patent application No. 202311740144.6 discloses an ultrafiltration membrane fiber drying device for ultrafiltration membrane fiber production, which includes a base block, a clamping and flipping mechanism for repositioning, clamping and flipping the ultrafiltration membrane fiber, a positioning mechanism for precisely positioning the ultrafiltration membrane fiber, and a moving drying mechanism for repositioning, drying and manipulating the ultrafiltration membrane fiber.

[0004] The bundled ultrafiltration membrane fibers need to be air-dried to allow them to dry gradually. However, with current technology, the ultrafiltration membrane fibers are bundled together, which leads to uneven drying and makes it difficult to dry them thoroughly. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a deformation-resistant and uniform air distribution structure for drying ultrafiltration membrane fibers, thereby solving the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention is implemented through the following technical solution: a deformation-resistant and uniform air distribution structure for drying ultrafiltration membrane fibers, comprising a loading shell, wherein a membrane spreading assembly is disposed inside the loading shell, and a vibration assembly is fixedly connected to the outer wall of the loading shell;

[0007] The film spreading assembly includes:

[0008] The first motor is fixedly connected to the bottom of the loading shell;

[0009] The spiral blade is disposed inside the loading shell, and the top output shaft of the first motor is fixedly connected to the bottom of the spiral blade;

[0010] A support net is fixedly connected inside the loading shell and is located at the top of the helical blades.

[0011] Preferably, the loading shell has a cavity structure inside and several air inlets. An air outlet grid is provided at the bottom of the spiral blade inside the loading shell. The spiral blade is driven by the first motor to push the air, which will create a negative pressure at the bottom of the spiral blade. This will further create a negative pressure inside the loading shell, so that the outside air enters the loading shell through the air inlets and flows to the bottom of the spiral blade through the air outlet grid.

[0012] Preferably, an adsorption grid is provided inside the loading shell at the top of the support net, and several inner protrusions are provided on the inner wall of the loading shell. When a negative pressure is formed inside the loading shell, the air pressure will push the ultrafiltration membrane fibers into the adsorption grid, so that the ultrafiltration membrane fibers are stuck between two inner protrusions. The inner protrusions can enhance the friction between the ultrafiltration membrane fibers and the inner wall of the loading shell, and further fix the outer side of the ultrafiltration membrane fibers.

[0013] Preferably, a second motor is fixedly connected to the bottom of the support net, and a clamping column is fixedly connected to the top of the second motor.

[0014] Preferably, the clamping column is provided with two extrusion plates inside, and extrusion rollers are movably connected to the outer sides of the two extrusion plates. Multiple extrusion springs are provided between the two extrusion plates, and the two ends of the extrusion springs are respectively fixedly connected to the corresponding extrusion plates. When the extrusion plates are pushed down into the clamping column, the extrusion rollers can contact the corresponding contact surfaces, reducing the resistance to pushing the extrusion plates down. At the same time, the extrusion rollers will roll on the surface of the ultrafiltration membrane fibers to avoid friction and damage to the ultrafiltration membrane fibers.

[0015] Preferably, the vibration assembly includes an impact column, which is movably connected inside the loading shell. A flexible wheel is movably connected to one end of the impact column inside the loading shell. The flexible wheel is a flexible structure. A limiting ring is provided on the outer wall of the impact column outside the loading shell. When the impact column is pushed inward into the loading shell, the flexible wheel inside the impact column can impact the outer side of the ultrafiltration membrane fibers inside the loading shell, causing the ultrafiltration membrane fibers to wrinkle. During this process, the flexible wheel will be pushed and roll when it comes into contact with the ultrafiltration membrane fibers to avoid scratching and damaging the ultrafiltration membrane fibers. When the impact column is pushed inward into the loading shell, the limiting ring can play a limiting role to prevent the impact column from completely entering the loading shell.

[0016] Preferably, a support platform is fixedly connected to the outer wall of the loading shell, and a rotating ring is movably connected inside the support platform via a bearing. A pushing block is fixedly connected to the inner wall of the rotating ring at the position corresponding to the impact column.

[0017] Preferably, a third motor is fixedly connected to the outer wall of the loading shell, and a drive gear is fixedly connected to the outer output shaft of the third motor. The top of the support platform is provided with teeth that mesh with the drive gear. When the third motor drives the drive gear to rotate, it can drive the rotating ring to rotate through the meshing teeth.

[0018] This invention provides a deformation-resistant and uniform air distribution structure for drying ultrafiltration membrane fibers. It has the following beneficial effects:

[0019] 1. The ultrafiltration membrane fiber drying anti-deformation uniform air distribution structure uses a clamping column to clamp one end of the bundled ultrafiltration membrane fibers. Then, a second motor drives the clamping column to rotate intermittently in the forward and reverse directions. This allows the gaps between the layers of the ultrafiltration membrane fibers to be evenly blown by the airflow, thereby uniformly drying the ultrafiltration membrane fibers and improving the drying effect.

[0020] 2. The ultrafiltration membrane fiber drying uses a deformation-resistant and uniform air distribution structure. By pushing the inclined block to push the impact column, the ultrafiltration membrane fiber is impacted. The liquid attached to the surface of the ultrafiltration membrane fiber will be removed from the surface of the ultrafiltration membrane fiber under the impact, so that the airflow can carry away the liquid and dry the surface of the ultrafiltration membrane fiber, thereby improving the drying effect of the ultrafiltration membrane fiber.

[0021] 3. The anti-deformation uniform air distribution structure for drying ultrafiltration membrane fibers causes the loading shell to vibrate when the limiting ring impacts the outer wall of the loading shell. This vibration is then transmitted to the support mesh, which facilitates the airflow to dry the liquid attached to the equipment. This reduces the amount of liquid remaining on the surface of the equipment during continuous operation and indirectly improves the drying effect of the ultrafiltration membrane fibers.

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0033] Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the invention, and should not be construed as limiting the invention.

[0034] Example 1: Please refer to Figure 1-8 The present invention provides a technical solution: a deformation-resistant and uniform air distribution structure for drying ultrafiltration membrane fibers, comprising a loading shell 1, a membrane spreading assembly 2 disposed inside the loading shell 1, and a vibration assembly 3 fixedly connected to the outer wall of the loading shell 1.

[0035] The film spreading assembly 2 includes:

[0036] The first motor 21 is fixedly connected to the bottom of the loading shell 1;

[0037] The spiral blade 22 is disposed inside the loading shell 1, and the top output shaft of the first motor 21 is fixedly connected to the bottom of the spiral blade 22.

[0038] Support net 23 is fixedly connected inside the loading shell 1 and is located at the top of the spiral blade 22.

[0039] The rolled-up ultrafiltration membrane fibers are placed inside the loading shell 1, so that the ultrafiltration membrane fibers are on top of the adsorption grid 24 inside the loading shell 1, and the ultrafiltration membrane fibers are fixed by the membrane spreading assembly 2. Then, the first motor 21 is started, and the first motor 21 drives the spiral blades 22 to rotate. The spiral blades 22 push the air to form an airflow. The airflow flows upward through the bottom of the support net 23. The flowing airflow can pass through the gaps between the ultrafiltration membrane fibers and dry the ultrafiltration membrane fibers.

[0040] The loading shell 1 has a cavity structure inside, and the loading shell 1 has several air inlets 26. An air outlet grid 25 is opened at the bottom of the spiral blade 22 inside the loading shell 1.

[0041] The spiral blade 22 is driven by the first motor 21 to push the air, which will create a negative pressure at the bottom of the spiral blade 22, and further create a negative pressure inside the loading shell 1. This allows the external air to enter the loading shell 1 through the air inlet 26 and then flow to the bottom of the spiral blade 22 through the air outlet grid 25.

[0042] Inside the loading shell 1, an adsorption grid 24 is provided on top of the support net 23. Several inner protrusions 27 are provided on the inner wall of the loading shell 1. When a negative pressure is formed inside the loading shell 1, the air pressure will push the ultrafiltration membrane fiber into the adsorption grid 24, so that the ultrafiltration membrane fiber is stuck between two inner protrusions 27. The inner protrusions 27 can enhance the friction between the ultrafiltration membrane fiber and the inner wall of the loading shell 1, and further fix the outer side of the ultrafiltration membrane fiber.

[0043] The spiral blades 22 are driven to push air, which creates a negative pressure inside the loading shell 1. After the ultrafiltration membrane fiber is placed inside the loading shell 1, the ultrafiltration membrane fiber will stretch towards the edge under its own expansion force, so that the edge of the ultrafiltration membrane fiber adheres to the inner wall of the loading shell 1. After the negative pressure is formed inside the loading shell 1, the external atmospheric pressure will push the ultrafiltration membrane fiber into the loading shell 1, so that the outer side of the ultrafiltration membrane fiber adheres tightly to the inner wall of the loading shell 1, thereby adsorbing and fixing the outer layer of the rolled-up ultrafiltration membrane fiber, which can prevent the upward airflow from blowing the ultrafiltration membrane fiber off. At the same time, the inner protrusion 27 can enhance the friction between the ultrafiltration membrane fiber and the inner wall of the loading shell 1, further fixing the ultrafiltration membrane fiber. Meanwhile, the airflow can flow through the air inlet 26 to the air outlet grid 25, which can dry the outermost surface of the ultrafiltration membrane fiber.

[0044] The gaps between the rolled ultrafiltration membrane fibers are small, the airflow speed is relatively slow, and the drying effect is poor. Increasing the gaps between the layers can improve the airflow drying effect and the drying speed. The support net 23 is fixedly connected to the bottom of the second motor 28, and the second motor 28 is fixedly connected to the top of the clamping column 29.

[0045] The clamping column 29 is provided with two extrusion plates 210 inside, and extrusion rollers 212 are movably connected to the outer side of each of the two extrusion plates 210. Multiple extrusion springs 211 are provided between the two extrusion plates 210, and the two ends of the extrusion springs 211 are fixedly connected to the corresponding extrusion plates 210. When the extrusion plates 210 are pushed down into the clamping column 29, the extrusion rollers 212 can contact the corresponding contact surfaces, reducing the resistance encountered when pushing the extrusion plates 210 down. At the same time, the extrusion rollers 212 will roll on the surface of the ultrafiltration membrane fibers to avoid friction and damage to the ultrafiltration membrane fibers.

[0046] Beforehand, the extrusion plate 210 is removed from the inside of the clamping column 29. One end of the ultrafiltration membrane fiber is inserted into the gap in the middle of the clamping column 29. Then, the extrusion plate 210 is inserted into the clamping column 29. The two extrusion plates 210 are pushed by the extrusion spring 211 and squeeze the ultrafiltration membrane fiber through the extrusion roller 212. When the ultrafiltration membrane fiber moves outward, the extrusion roller 212 cannot roll outward, which can fix the ultrafiltration membrane fiber in the horizontal direction, thereby increasing the gap between the layers of the ultrafiltration membrane fiber.

[0047] During the drying process, the second motor 28 drives the clamping column 29 to rotate. Since the ultrafiltration membrane fibers are adsorbed and fixed by the adsorption grid 24 on the outside, the clamping column 29 can gradually roll the ultrafiltration membrane fibers onto the outer wall of the clamping column 29 through the side where the ultrafiltration membrane fibers are fixed. This can expand the gap between the layers of ultrafiltration membrane fibers and move them outward. The second motor 28 drives the clamping column 29 to rotate intermittently in the forward and reverse directions, so that the gap between the layers of ultrafiltration membrane fibers can be evenly blown by the airflow.

[0048] Example 2: Please refer to Figure 1-9 Based on Embodiment 1, the present invention provides a technical solution:

[0049] The vibration assembly 3 includes an impact column 36, which is movably connected inside the loading shell 1. One end of the impact column 36 inside the loading shell 1 is movably connected to a soft wheel 38, which is a flexible structure. A limit ring 37 is provided on the outer wall of the impact column 36 outside the loading shell 1.

[0050] When the impact column 36 is pushed into the loading shell 1, the soft wheel 38 inside the impact column 36 can impact the outer side of the ultrafiltration membrane fiber inside the loading shell 1, causing the ultrafiltration membrane fiber to wrinkle. During this process, the soft wheel 38 will be pushed and roll when it comes into contact with the ultrafiltration membrane fiber, so as to avoid scratching the ultrafiltration membrane fiber and causing damage to the ultrafiltration membrane fiber.

[0051] When the impact post 36 is pushed toward the inside of the loading shell 1, the limiting ring 37 can play a limiting role to prevent the impact post 36 from completely entering the loading shell 1.

[0052] A support platform 31 is fixedly connected to the outer wall of the loading shell 1. A rotating ring 32 is movably connected inside the support platform 31 via a bearing. A pushing inclined block 33 is fixedly connected to the inner wall of the rotating ring 32 at the corresponding position of the impact column 36.

[0053] A third motor 34 is fixedly connected to the outer wall of the loading shell 1. A drive gear 35 is fixedly connected to the outer output shaft of the third motor 34. The top of the support platform 31 is provided with teeth that mesh with the drive gear 35. When the third motor 34 drives the drive gear 35 to rotate, it can drive the rotating ring 32 to rotate through the meshing teeth.

[0054] After the ultrafiltration membrane fiber is placed on top of the support mesh 23 inside the loading shell 1 and the first motor 21 is started, the third motor 34 is started, causing the third motor 34 to drive the drive gear 35 to rotate. The gears further drive the rotating ring 32 to rotate through the meshing teeth. During the rotation, the rotating ring 32 can push the impact column 36 into the loading shell 1 by pushing the inclined surface of the inclined block 33. The soft wheel 38 on the inner side of the impact column 36 impacts the ultrafiltration membrane fiber, causing the liquid attached to the surface of the ultrafiltration membrane fiber to detach from the surface of the ultrafiltration membrane fiber under the impact, so that the airflow can carry away the liquid and dry the surface of the ultrafiltration membrane fiber. After the impact column 36 is pushed into the loading shell 1 to the limit, the limiting ring 37 will hit the outer wall of the loading shell 1, causing the impact column 36 to stop moving. Then, under the action of air pressure, the outer layer of the ultrafiltration membrane fiber will re-adhere to the inner wall of the loading shell 1, and the soft wheel 38 will push the impact column 36 outward, so that the impact column 36 resets and can continue to work in cycles.

[0055] In addition, when the limiting ring 37 impacts the outer wall of the loading shell 1, it will cause the loading shell 1 to vibrate and transmit the vibration to the support net 23, which can facilitate the airflow to dry the liquid attached to the equipment and reduce the liquid residue on the surface of the equipment during continuous operation.

[0056] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
