Technical Field
[0001] This utility model relates to the field of water treatment technology, and in particular to a membrane filament winding and collection device. Background Technology
[0002] Ultrafiltration is a sieving process that utilizes membrane separation technology. Driven by the pressure difference across the membrane, and using the ultrafiltration membrane as the filtration medium, under certain pressure, when the feed solution flows across the membrane surface, the numerous tiny micropores densely distributed on the ultrafiltration membrane surface only allow water and small molecules to pass through, becoming the permeate. Substances in the feed solution with a volume larger than the micropore size of the membrane surface are retained on the feed side of the membrane, becoming the concentrate. Thus, the purification, separation, and concentration of the feed solution are achieved. Each meter of ultrafiltration membrane fiber has approximately 6 billion 0.01-micron micropores, whose pore size only allows water molecules, beneficial minerals, and trace elements in the water to pass through. Since the smallest bacteria are larger than 0.02 microns, bacteria, as well as colloids, rust, suspended solids, silt, and large organic molecules, which are much larger than bacteria, can be retained by the ultrafiltration membrane, thereby achieving the purification process.
[0003] As an important water treatment material, ultrafiltration membranes are widely used in sewage treatment, industrial wastewater treatment, and other fields. The optimization and efficiency of membrane fiber production equipment directly affect the benefits and costs of water treatment; the membrane fiber production process, such as... Figure 4 As shown, the process includes preparing a feed solution by adding PVDF, DMAC, and additives to a mixing tank 13 in a certain proportion and stirring to dissolve them. The feed solution is then degassed under negative pressure. After complete degassed, a hollow hook-and-loop rope made of PET material is fed to the production line using a rope feeder 15 at the other end, utilizing the tension control system of the first winding wheel 16 and the rope feeder 15. Simultaneously, positive pressure is applied to the tank to begin spinning. The feed solution passes through pipes, a filter 14, and a spinneret 17 before emerging as filaments, forming a membrane filament encapsulating the PET rope. The outer diameter of the membrane filament is determined by a feed pump. Rotation speed control: After the membrane fibers are pressed into the first gel tank 19 by the roller 18, they are initially shaped under the action of the liquid in the tank. At this time, the pore size of the membrane fibers has been formed. The pore formation principle is a double diffusion process. The main influencing factors are the concentration and temperature of the first gel tank 19, the temperature of the feed liquid, and the distance between the spinneret 17 and the liquid surface of the first gel tank 19. After the molecular weight is distributed in a certain way, the membrane fibers are further separated by the second gel tank 20. Then, they are collected into the tank by the collection device 21. After the post-processing steps of soaking and drying, the finished membrane fibers are finally formed.
[0004] Existing collection devices such as Figure 5As shown, after the membrane filaments soaked in the second gel tank 20 are wound around the axially horizontal second winding wheel 22, an axially vertical turntable is set on the ground in front of the second winding wheel 22, and a cylinder 23 is placed on the turntable. One end of the membrane filament is pulled into the cylinder 23. Under the friction between the membrane filament and the cylinder 23, as the second winding wheel 22 and the cylinder 23 rotate, the membrane filament is placed into the cylinder 23. However, in the existing collection device, the rotation speed of the second winding wheel and the cylinder needs to be precisely calculated. If the rotation speed of the second winding wheel 22 and the cylinder do not correspond, the membrane filaments will be arranged irregularly, resulting in low production efficiency and waste.
[0005] Therefore, in order to address the above problems, this utility model urgently needs to provide a membrane filament winding and collecting device. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0032] like Figure 1 , Figure 3As shown, the present invention provides a membrane filament winding and collecting device, including a fixing plate 9, a rotary motor 1 fixedly connected to the fixing plate 9, the rotating shaft of the rotary motor 1 extending downward and fixedly connected to a rotating cylinder 4, and a spiral guide groove 5 opened on the rotating cylinder 4.
[0033] The bottom of the rotating cylinder 4 is also provided with an outwardly extending telescopic guide rod 11. A first guide ring 10 is provided at the fixed end of the guide rod 11, and a second guide ring 12 is provided at the telescopic end of the guide rod 11.
[0034] It also includes a collection bucket 7 located below the rotating cylinder 4 for collecting membrane fibers, the collection bucket 7 being coaxially arranged with the rotating cylinder 4; the telescopic end of the guide rod 11 is located above the opening of the collection bucket 7.
[0035] The membrane filament winding and collecting device provided by this utility model winds the membrane filaments from the second winding wheel 22 into the guide groove 5, then passes them sequentially through the first guide ring 10 and the second guide ring 12, and places the membrane filaments at the ends into the collecting bucket 7. Then, the rotating cylinder 4 is rotated by the rotary motor 1. Under the friction between the membrane filaments and the inner wall of the collecting bucket 7 and the pushing force of the second winding wheel 22, the membrane filaments are spirally coiled into the collecting bucket 7. Therefore, the rotation of the rotating cylinder 4 alone achieves the arrangement and collection of membrane filaments, while keeping the collecting bucket 7 stationary. The operation is simple, the production efficiency is improved, and the membrane filaments are collected efficiently. The rotating cylinder 4 of this utility model is provided with a guide groove 5, which avoids problems such as knotting during the collection of membrane filaments and solves the problem of waste and loss during the preparation process. At the same time, the collection position of the membrane filaments in the bucket can be freely controlled by the telescopic guide rod 11.
[0036] like Figure 2 As shown, the collection bucket 7 includes an outer shell 702 and an inner liner 701 disposed inside the outer shell 702. The tops of the outer shell 702 and the inner liner 701 are connected to each other. A conical protrusion 703 is provided at the bottom of the inner liner 701, and the axis of the conical protrusion 703 coincides with the axis of the rotary motor 1.
[0037] like Figure 1 , Figure 3 As shown, the guide rod 11 includes a fixed section 1101, a telescopic section 1102 and a free section 1103 connected in sequence. The fixed section 1101 and the telescopic section 1102 are slidably connected, and the free section 1103 is fixed to the far end of the telescopic section 1102. The first guide ring 10 is installed on the fixed section 1101 and the second guide ring 12 is installed on the free section 1103.
[0038] In this invention, the telescopic end 1102 is slid along the fixed section 1101 to adjust the distance between the second guide ring 12 and the rotating cylinder 4. The distance between the fixed section 1101 and the free section 1103 is quantitatively controlled by the scale lines set on the telescopic section 1102, which can adjust the coiling diameter of the membrane filament and thus control the size of the final finished membrane filament.
[0039] like Figure 1 , Figure 3 As shown, a mounting plate 8 is fixed to one end of the fixing plate 9. The mounting plate 8 is used to adhere to the wall and is fixed to the wall by bolts.
[0040] In this invention, bolts are used to install the fixing plate 9 on top of the collection bucket 7, and the rotating motor 1 is fixed during the collection process, thus extending the service life of the collection device.
[0041] like Figure 1 , Figure 3 As shown, the top and bottom of the rotating cylinder 4 are provided with an upper partition 3 and a lower partition 6 spaced apart, and one end of the guide rod 11 is connected to the outer edge of the lower partition 6.
[0042] In this invention, upper partition 3 and lower partition 6 are used to limit the membrane filaments at the upper and lower ends to avoid jamming caused by knotting or other reasons during the collection process.
[0043] like Figure 1 , Figure 3 As shown, the bottom of the rotary motor 1 is provided with a fixed flange 2, which is screwed to the fixed plate 9.
[0044] In this embodiment, a through hole is provided on the upper surface of the fixing plate 9, and the rotary motor 1 is fixedly connected to the top of the fixing plate 9. The rotating shaft of the rotary motor 1 passes through the through hole from top to bottom and is fixedly connected to the rotating cylinder 4.
[0045] In this embodiment, the bottom of the rotary motor 1 is bonded and fixed to the fixing plate 9.
[0046] like Figure 3 As shown, the extension section 1102 is provided with scale lines at intervals.
[0047] like Figure 2 As shown, the conical surface of the conical protrusion 703 is obtained by rotating an oblique parabola around the axis of the rotary motor 1 for one revolution. The angle between the normal of each point on the oblique parabola and the axis of the rotary motor 1 is 30°-45°.
[0048] In this invention, by placing the membrane fiber disc inside the inner liner 701, the irregular arrangement of the membrane fibers during the collection process is reduced due to the obstruction of the conical protrusion 703 and the friction between it and the membrane fibers, thus assisting in a more uniform arrangement of the membrane fibers and controlling waste caused during the production process.
[0049] The embodiments of this utility model include the following steps:
[0050] 1) After pulling the membrane filament from the second gel tank 20 and winding it from top to bottom into the guide groove 5, adjust the length of the telescopic section 1102 so that the distance between the second guide ring 12 and the first guide ring 10 meets the requirements. After passing the membrane filament through the first guide ring 10 and the second guide ring 12 in sequence, place it in the collection bucket 7.
[0051] 2) Run the rope feeder 15, the first winding wheel 16, and the rotary motor 1 at an appropriate speed. Under the friction between the membrane filaments and the collection bucket 7, the membrane filaments are evenly coiled into the collection bucket 7.
[0052] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
