Description

Technical Field

[0001] The invention relates to the technical field of reverse osmosis membrane processing, in particular to a processing device and a processing technology for a fiber used in a seawater desalination reverse osmosis membrane. Background Art

[0002] The seawater desalination reverse osmosis membrane is the core component in the seawater desalination process. Based on the selective permeability working principle of the membrane, it has the advantages of high efficiency, environmental protection, and easy operation. The reverse osmosis membrane allows water molecules to pass through, while preventing the permeability of impurities such as salt ions, metal ions, suspended matter, and microorganisms. Through the action of high pressure, water molecules in seawater pass through the membrane, while salt and impurities are blocked by the membrane, thereby achieving seawater desalination.

[0003] The fiber filaments of the seawater desalination reverse osmosis membrane are the polymer materials that make up the reverse osmosis membrane. These materials are processed into membranes through special processes and are used in the seawater desalination process. Common reverse osmosis membrane materials include cellulose acetate, aromatic polyamide, etc. They are processed into thin films with micro-nano pores through electrospinning, coating and other processes. They can effectively block salt and impurities in seawater and only allow water molecules to pass through, thereby achieving seawater desalination;

[0004] In the fiber processing process, after spinning by the spinning machine, the formed fiber needs to be rolled up and stored or transported to the reverse osmosis membrane equipment. However, the winding mechanism is mostly single-point winding, which can easily lead to uneven distribution of the fiber on the reel, resulting in local over-tightness or over-looseness, affecting product quality. Therefore, there is a lack of a processing device and processing technology for fibers for seawater desalination reverse osmosis membranes. Summary of the invention

A tooth block 18 is slidably connected inside the slide groove 16. The bottoms of the two tooth blocks 18 are both located inside the inner cavity 17. The top of the tooth block 18 is located on the upper surface of the frame 4 and a shaft sleeve 19 is fixed. Two screw barrels 20 are rotatably connected inside the inner cavity 17. A gear ring 22 is fixed on the outer surface of the screw barrel 20. The gear ring 22 is meshed with the bottom of the gear block 18. A screw rod 21 is threadedly connected inside the screw barrel 20. The right ends of the two screw rods 21 are both penetrated. It passes through the right side of the frame 4 and is fixedly connected to the connecting frame 24. The two tooth blocks 18 are both threadedly connected with screw rods 23 at the bottom.

A slot 26 is opened at the center of the left side of the gear 25, and two limit blocks 27 are integrally formed inside the slot 26.

[0044] The reel assembly 3 includes a reel 30, and a shaft 31 is fixed to the left and right ends of the reel 30.

The two sliders 36 are fixedly connected to the protective shell 2 37.

[0045] When 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, and the motor 7 is operated to rotate the worm 8, the rectangular rod 13, the rotating drum 14, and the gear 15 at the same time. Under the transmission of the gear 15, the gear 25 drives the shaft 31 and the winding drum 30 to rotate, so as to wind up 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 incomplete gear 11 drives the driving gear 12 to rotate intermittently, so that the frame assembly 2 drives the winding drum assembly 3 to move intermittently, so that the fiber filament is more evenly wound on the outer surface of the winding drum 30, avoiding the local over-tightness or over-looseness caused by single-point winding accumulation, thereby improving the uniformity of winding;

[0046] After the winding drum 30 is fully loaded, the personnel rotates the second protective shell 37 to make the slider 36 slide along the arc groove 35, so that the second protective shell 37 and the first protective shell 34 wrap the winding drum 30 and the fiber filaments for protection, effectively preventing dust, impurities and other external pollutants from adhering to the fiber filaments, maintaining the cleanliness of the fiber filaments, improving product quality, reducing mechanical impact and damage to the drum during transportation and storage, and extending the service life of the drum and the fiber filaments;

[0047] When the rotating wheel 45 is rotated, the two screw rods 23 rotate, and the two tooth blocks 18 will drive the two shaft sleeves 19 to move away from each other, thereby away from the shaft rod 31, and under the meshing action, the gear ring 20 drives the screw barrel 22 to rotate, and the screw rod 21 will push the connecting frame 24 to move right. At this time, when the gear 2 25 moves right, the shaft rod 31 on the right side is separated from its interior. At this time, the reel assembly 3 loses its limit, and the reel assembly 3 and the wound fiber filaments inside can be moved and transported for storage or seawater desalination reverse osmosis membrane production; when the connecting frame 24 moves right, it drives the gear 1 15 and the rotating drum 14 to move right.

[0048] like Figure 7 , Fig.10 As shown, a positioning hole 38 is formed inside the turntable 33 on the left side, and a positioning rod 29 is connected to the left side of the frame 4. The right end of the positioning rod 29 is located inside the positioning hole 38. When disassembling, the positioning rod 29 is pulled to the left to disengage it from the positioning hole 38, thereby releasing the positioning of the turntable 33 and the protective shell.

[0049] like Fig.10 As shown, a spring slot 39 is formed inside the turntable 33 on the right side, and a clamp plate 40 is slidably connected inside the spring slot 39. A tension spring 41 is fixed between the lower surface of the clamp plate 40 and the upper surface of the spring slot 39. The left end of the clamp plate 40 is located above the winding drum 30. The clamp plate 40 is pulled up to raise it. After it rises, the fiber thread head is placed underneath, and then the clamp plate 40 is pulled by the tension spring 41 to clamp the fiber thread end, so that it can be stably wound up after the winding drum 30 rotates.

[0050] like Fig.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 winding up the fiber filaments 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 Fig.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 body 4 are rotatably connected with rollers 44, and the outer surface of the roller 44 fits under the inner surface of the slide rail 1, so that the auxiliary frame body 4 slides inside the slide rail 1.

[0053] like Figure 3 , Figure 6 As shown, a plurality of tooth grooves 46 are provided at the front and rear sides of the inner surface of the slide rail 1, and the slide rail 1 is meshedly connected with the two driving gears 12 through the tooth grooves 46. When the two driving gears 12 rotate, the frame assembly 2 is able to drive the reel assembly 3 to slide laterally inside the slide rail 1 through the meshing connection, so as to adjust the position of the fiber filaments during winding, avoid fiber filament nodules caused by single winding, make the winding more uniform, avoid local over-tightening or over-loosening, and thus improve the uniformity of winding.

[0054] like Figure 4 , Fig. 9 , Fig.10 As shown, the two shafts 31 are respectively located inside the two shaft grooves 28, the right end of the shaft 31 on the right side is located inside the slider 36, and the limit block 27 is located inside 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 shaft rod 31 on the right side, and the inner surface of the shaft sleeve 19 is in close contact with the outer surface of the shaft rod 31 on the right side. The two shaft sleeves 19 are used to limit the position of the winding drum assembly 3 and the frame assembly 2, and the winding drum assembly 3 cannot be separated from the shaft groove 28 under the limit of the two shaft sleeves 19, so that the fiber yarn can be wound in a stable rotation. Fig. 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.
