Description

Technical Field

[0001] The present invention relates to the technical field of reverse osmosis membrane processing, and specifically to a processing device and processing technology for fibers used in seawater desalination reverse osmosis membranes. Background Technique

[0002] Seawater desalination reverse osmosis membranes are the core components in the seawater desalination process. Based on the working principle of the selective permeability of the membrane, they have advantages such as high efficiency, environmental protection, and simple operation. The reverse osmosis membrane allows water molecules to pass through while blocking the passage of salt ions, metal ions, suspended solids, microorganisms, and other impurities. Through the action of high pressure, the water molecules in seawater pass through the membrane, while the salts and impurities are blocked by the membrane, thus achieving seawater desalination.

[0003] The fiber filaments of seawater desalination reverse osmosis membranes are the polymer materials that make up the reverse osmosis membrane. These materials are processed into a film shape through special processes for use in the seawater desalination process. Common reverse osmosis membrane materials include cellulose acetate, aromatic polyamides, etc. They are processed into thin films with micro-nano scale pore diameters through processes such as electrospinning and coating, which can effectively block the salts and impurities in seawater and only allow water molecules to pass through, thus achieving seawater desalination;

[0004] During the processing of fiber filaments, after spinning by a spinning machine, the formed fiber filaments need to be wound up for storage or transported to the reverse osmosis membrane equipment. However, most winding mechanisms are single-point winding, which easily leads to uneven distribution of the silk threads on the reel, resulting in local over-tightening or over-loosening, affecting the product quality. Therefore, there is a lack of a processing device and processing technology for fibers used in seawater desalination reverse osmosis membranes. Summary of the Invention

Detailed implementation manners

[0041] The present invention will be described in detail below with reference to the drawings and in combination with embodiments. It should be noted that, without conflict, the embodiments in the present application and the features in the embodiments may be combined with each other.

[0042] As Figure 2-11 shown, according to one aspect of the present invention, a processing device for fibers used in reverse osmosis membranes for seawater desalination is provided, including a reaction kettle, a spinning machine, and a winding mechanism.

Worms 9 are meshed and connected to the front and rear sides of the outer surface of the worm 8. A rotating rod 10 is fixed in the middle of the worm wheel 9. The bottom end of the rotating rod 10 penetrates into the upper surface of the bottom groove 6, and an incomplete gear 11 is fixed. Two driving gears 12 are rotatably connected to the upper surface of the bottom groove 6. The driving gear 12 is meshed and connected to the incomplete gear 11. A rectangular rod 13 is fixed to the right end of the worm 8. A rotating cylinder 14 is slidably connected to the outer surface of the rectangular rod 13. The right end of the rotating cylinder 14 penetrates to the right side of the frame body 4 and is rotatably connected to a connecting frame 24. A gear one 15 is fixed between the right side of the frame body 4 and the connecting frame 24 on the outer surface of the rotating cylinder 14. Penetrating shaft grooves 28 are opened on the left and right sides of the upper surface of the frame body 4. Sliding grooves 16 are opened in front of and behind the shaft groove 28 on the right side of the upper surface of the frame body 4. An inner cavity 17 is opened at the bottom of the two sliding grooves 16. A tooth block 18 is slidably connected in the sliding groove 16. The bottoms of the two tooth blocks 18 are both located inside the inner cavity 17. A shaft sleeve 19 is fixed to the top end of the tooth block 18 on the upper surface of the frame body 4. Two screw cylinders 20 are rotatably connected to the inner cavity 17. A tooth ring 22 is fixed to the outer surface of the screw cylinder 20. The tooth ring 22 is meshed and connected to the bottom of the tooth block 18. A screw rod 21 is threadedly connected to the inside of the screw cylinder 20. The right ends of the two screw rods 21 both penetrate to the right side of the frame body 4 and are both fixed to the connecting frame 24. Threaded rods 23 are threadedly connected to the lower parts of the two tooth blocks 18. The two threaded rods 23 are fixedly connected. The front end of the threaded rod 23 located in the front penetrates to the front surface of the frame body 4 and is fixed to a runner 45. A gear two 25 is rotatably connected to the left side of the connecting frame 24. The gear two 25 is meshed and connected to the gear one 15. A slot 26 is opened at the center of the left side of the gear two 25. Two limiting blocks 27 are integrally formed inside the slot 26.

[0044] The reel assembly 3 includes a winding reel 30. Shaft rods 31 are fixed to the left and right ends of the winding reel 30. Limiting grooves 32 are symmetrically opened on the outer surface of the shaft rod 31 located on the right side. A turntable 33 is rotatably connected to the outer surface of the shaft rod 31. A protective shell one 34 is fixed to the rear of the outer surfaces of the two turntables 33. Arc grooves 35 are opened in front of the opposite sides of the two turntables 33. A protective shell two 37 is slidably connected to the inside of the protective shell one 34. A slider 36 is slidably connected in the arc groove 35. Both sliders 36 are fixed to the protective shell two 37;

[0045] In use, the initial head end of the fiber filament is connected to the right side of the outer surface of the winding drum 30. When the motor 7 operates, the worm 8, the rectangular rod 13, the rotating cylinder 14, and the first gear 15 rotate simultaneously. Driven by the first gear 15, the second gear 25 drives the shaft rod 31 and the winding drum 30 to rotate, thereby winding the fiber filament. At the same time, the rotating worm 8 drives the rotating rod 10 and the incomplete gear 11 to rotate through the worm gear 9, and the intermittent rotation of the incomplete gear 11 drives the driving gear 12 to rotate intermittently, causing the frame assembly 2 to drive the winding drum assembly 3 to move intermittently, making the fiber filament wind more evenly on the outer surface of the winding drum 30, avoiding local over-tightening or over-loosening caused by single-point winding and accumulation, thereby improving the winding uniformity;

[0046] After the winding drum 30 is fully wound, the operator rotates the second protective shell 37, causing the slider 36 to slide along the arc groove 35, so that the second protective shell 37 and the first protective shell 34 wrap and protect the winding drum 30 and the fiber filament, effectively preventing external pollutants such as dust and impurities from adhering to the fiber filament, maintaining the cleanliness of the fiber filament, improving the product quality, reducing the mechanical impact and damage suffered by the winding drum during transportation and storage, and extending the service life of the winding drum and the fiber filament;

[0047] When the runner 45 is rotated, the two lead screws 23 rotate, and the two tooth blocks 18 drive the two shaft sleeves 19 to move away from each other, thus moving away from the shaft rod 31. And under the meshing action, the toothed ring 20 drives the screw barrel 22 to rotate, and the screw 21 pushes the connecting frame 24 to move to the right. At this time, when the second gear 25 moves to the right, the shaft rod 31 on the right side disengages from its interior, and at this time the winding drum assembly 3 loses its limit, and the winding drum assembly 3 and the fiber filament wound inside can be moved and transported for storage or the production of reverse osmosis membranes for seawater desalination; when the connecting frame 24 moves to the right, it drives the first gear 15 and the rotating cylinder 14 to move to the right.

[0048] As Figure 7 、 Figure 10 shown, a positioning hole 38 is penetrated and opened inside the left turntable 33, and a positioning rod 29 is penetrated and connected to the left side of the frame body 4. The right end of the positioning rod 29 is located inside the positioning hole 38. During disassembly, the positioning rod 29 is pulled to the left to disengage it from the positioning hole 38, releasing the positioning of the turntable 33 and the protective shell.

[0049] As Figure 10 shown, a spring groove 39 is penetrated and opened inside the right turntable 33, and a clamping plate 40 is slidably connected inside the spring groove 39. A tension spring 41 is fixedly connected between the lower surface of the clamping plate 40 and the upper surface inside the spring groove 39. The left end of the clamping plate 40 is located above the winding drum 30. By pulling the clamping plate 40 to make it rise, after rising, the fiber filament head is placed below, and then the clamping plate 40 is pulled by the tension spring 41 to clamp the fiber filament end, so that it can be stably wound after the winding drum 30 rotates.

[0050] As Figure 10As shown, the top of the protective shell 2 37 is located in front of the protective shell 1 34 and is integrally formed with a buckle plate 42. The top of the buckle plate 42 is higher than the top of the protective shell 1 34. By pulling the buckle plate 42, the winding drum 30 after the fiber filaments are wound can be wrapped to protect the fiber filaments and prevent the residual solution on the fiber filaments from splashing during movement, causing pollution or injury to personnel.

[0051] like Figure 10 As shown, a handle 43 is fixed on the outer surface of the protective shell 34, and the reel assembly 3 after winding the fiber filaments is lifted and moved by the handle 43.

[0052] like Figure 4 As shown, the left and right ends of the bottom of the frame 4 are rotatably connected to rollers 44, and the outer surface of the roller 44 fits under the inner surface of the slide rail 1, and the auxiliary frame 4 slides inside the slide rail 1.

[0053] like Figure 3 、 Figure 6 As shown, a plurality of tooth grooves 46 are provided on the front and rear sides of the inner surface of the slide rail 1. The slide rail 1 is meshed with the two drive gears 12 through the tooth grooves 46. When the two drive gears 12 rotate, the meshing connection enables the frame assembly 2 to drive the reel assembly 3 to slide laterally inside the slide rail 1, thereby adjusting the position of the fiber filaments during winding, avoiding fiber filament nodules caused by single winding, making the winding more uniform, avoiding local over-tightness or over-looseness, and thus improving the uniformity of winding.

[0054] like Figure 4 、 Figure 9 、 Figure 10 As shown, the two shafts 31 are respectively located in the two shaft grooves 28, the right end of the right shaft 31 is located in the slider 36, and the limit block 27 is located in the limit groove 32, so that when the gear 2 25 rotates, the shaft 31 can be used to rotate the winding drum 30 to perform the fiber winding operation;

[0055] The two shaft sleeves 19 are located above the outer surface of the right shaft rod 31, and the inner surface of the shaft sleeve 19 is in contact with the outer surface of the right shaft rod 31. The two shaft sleeves 19 are used to limit the connection between the reel assembly 3 and the frame assembly 2, and the reel assembly 3 cannot be separated from the shaft groove 28 under the limit of the two shaft sleeves 19, so that the reel assembly 3 can rotate stably to perform the fiber winding operation; Figure 9 The two shaft sleeves 19 are in a movable open state, in which the reel assembly 3 can be separated from the frame assembly 2, and a new reel assembly 3 can be replaced to continue the winding operation.

[0056] like Figure 1 As shown, according to one aspect of the present invention, a process for processing fibers for seawater desalination reverse osmosis membranes is provided, using a processing device for seawater desalination reverse osmosis membrane fibers, comprising the following steps:

[0057] S1. Preparation of Spinning Solution

[0058] A polyamic acid solution is prepared from pyromellitic dianhydride (PMDA) and 4,4'-diaminodiphenyl ether (ODA), and an electrospinning solution of polyimide is generated through thermal cyclization in a reaction kettle;

[0059] S2. Spinning by Spinning Machine

[0060] The spinning solution is spun into fibers using a spinning machine;

[0061] S3. Winding of Fiber Yarns

[0062] After spinning is completed, the fiber yarns are orderly wound by a winding mechanism, which is convenient for the subsequent processing and use of reverse osmosis membranes for seawater desalination.

[0063] Certainly, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those of ordinary skill in the art within the scope of the essence of the present invention also fall within the protection scope of the present invention.
