[0002] Ion exchange membrane is a polymer membrane containing ionic groups and having the ability to selectively permeate ions in solution. Because its ion selective permeability is generally used in applications, it is also called ion selective permeability membrane.

[0003] Depending on the type of ions that pass through, the raw materials used are different, so the production process of ion exchange membranes is also different, such as the casting method of casting the polymer solution; the melt extrusion method of forming by melt extrusion, etc. In the casting method, the slurry is coated on the support and then scraped flat with a scraper. The existing scraper is relatively simple. If the material accumulates and solidifies on the scraper, it is easy to affect the quality of the ion exchange membrane produced subsequently. Summary of the invention

That is, the connecting ring can slide axially on the outer sleeve, and the two springs are provided so that the connecting ring is centrally arranged and meets the axial vibration of the first scraper when the lateral vibrator is working.

[0010] Preferably, the inner sleeve and the outer sleeve are fitted with a first dustproof ring at one end, and a second dustproof ring is fitted at the other end.

[0013] Preferably, handles are fixedly connected to the upper parts of both sides of the housing frame, and an opening is provided at the upper end of the housing frame. The handles are convenient for lifting and transferring the device.

[0014] Preferably, a control box is disposed at the upper end of the housing frame, and a control unit for controlling the movement of the vibrator is disposed inside the control box.

[0015] The beneficial effects of the present invention are as follows: 1. A vibrator is provided to vibrate the slurry to make it smooth, which is suitable for slurries of different viscosities. The vibrator is arranged vertically and horizontally, that is, the first scraper can vibrate in two directions. The vibration can shake off the material adhering to the first scraper, and at the same time, the shaken-off material can be accommodated and scraped flat in the gap generated by the vibration.

[0016] 2. The lower part of the first scraper is set with an upward tilted angle. During the up and down vibration process, the lower part of the first scraper tends to be horizontal, ensuring that the surface of the ion exchange membrane is flat after scraping.

[0023] like Figures 1 to 8 As shown, an ion exchange membrane scraping device includes a frame 1, the frame 1 is a thin shell member in the shape of a Chinese character "J", and through holes are arranged at the lower part of both sides of the frame 1 for installation of the device, and the ion exchange membrane sent out by the casting process is sent out from the bottom of the frame 1, and the lower end of the frame 1 is provided with a first scraper 5 and a second scraper 6 side by side, that is, the ion exchange membrane passes through the first scraper 5 once, and then passes through the second scraper 6, and the lower end of the second scraper 6 is semicircular, and the ion exchange membrane is scraped twice to ensure the stability of its performance, and the lower end of the frame 1 is fixedly connected with a plurality of connecting members 4, the upper part of the first scraper 5 is fixedly connected to the connecting member 4, and the side wall of the first scraper 5 is fixedly connected with a vibrator 13 in the vertical and horizontal directions. When the vertical and horizontal vibrators 13 are working, vibrations in the up-down and left-right directions are generated on the first scraper 5, thereby realizing the flatness of the ion exchange membrane.

[0024] Furthermore, the vibrator 13 includes a magnetic vibrator moving in a single direction, and a spring is provided in the vibration direction of the vibrator, and a coil interacting with the vibrator. The magnetic field generated by the coil being energized attracts or repels the vibrator, thereby realizing the vibration of the vibrator 13.

[0025] The side profile of the first scraper 5 is in a "Z" shape, that is, the upper section of the first scraper 5 is used to be fixedly connected to the connecting member 4, and the upward angle α between the lower section and the horizontal plane is 2 to 5°. The first scraper 5 deflects during the up and down vibration, and the amplitude of the up and down vibration is controlled so that the lower section of the first scraper 5 returns to a horizontal state during the vibration process, thereby ensuring the surface flatness of the ion exchange membrane. The outer side wall of the lower bend of the first scraper 5 is fixedly connected with a plurality of convex pieces 7 at equal distances. The spacing of the convex pieces 7 can be set with reference to the upper amplitude in the left and right directions. With the vibration in the left and right directions, the convex pieces 7 can be scraped left and right, ensuring the consistency of the ion exchange membrane in the left and right directions.

[0026] The connecting member 4 includes a connecting seat 41, the upper end of which is fixedly connected to the upper top wall of the shell frame 1, and a connecting shaft 46 is fixedly connected to one side of the connecting seat 41, and an inner sleeve 49 is sleeved on the connecting shaft 46, and the inner sleeve 49 and the connecting shaft 46 are fixedly connected by a spline, and an outer sleeve 414 is rotatably sleeved on the inner sleeve 49, and a connecting ring 43 is sleeved on the outer sleeve 414, and the same connecting ring 43 is sleeved on the outer sleeve 414 by a spline, and the requirements of left and right vibration are met at the same time, and the connecting ring 43 slides axially on the outer sleeve 414, and the side wall of the connecting ring 43 is fixedly connected to a connecting rod 47, and a threaded hole is set on the connecting rod 47, and the upper part of the first scraper 5 is fixedly connected to the connecting rod 47.

[0028] A spring piece 412 is arranged on the inner sleeve 49. The spring piece 412 is a metal sheet with good flexibility. A fixing bolt 413 is inserted in the middle of the spring piece 412. Two fixing bolts 413 are arranged, and the fixing bolt 413 is threadedly connected to the inner sleeve 49. A threaded hole is opened on the side wall of the inner sleeve 49, and the fixing bolt 413 is threadedly engaged in the threaded hole. The two sides of the spring piece 412 are bent, specifically multiple S-shaped bends, so that the spring piece 412 has the ability to deform, thereby greatly improving the elastic potential energy, and the edge is embedded in the interior of the outer sleeve 414, that is, without the action of external force, the relative position of the inner sleeve 49 and the outer cylinder 414 will not change, and when the inner sleeve 49 and the outer cylinder 414 rotate relative to each other, the spring piece 412 deforms to store elastic potential energy. After the force is lost, the inner sleeve 49 and the outer cylinder 414 return to their initial positions. This structure meets the requirements of up and down vibration.

A convex ring 415 is provided at one end of the outer sleeve 414, and a second spring 42 is provided between the convex ring 415 and the connecting ring 43, and between the connecting ring 43 and the retaining ring 44. At the same time, the retaining ring 44 is also used to support the second spring 42. Under the support of the two second springs 42, the connecting ring 43 is in a centered state, and this structure meets the requirements of the left and right vibration displacement of the first scraper 5.

The end of the second scraper 6 is fixedly connected to the connecting block 11, and the fixed support of the second scraper 6 is achieved through the folding plate 8 and the connecting piece 11. It should be noted that the upper part of the second scraper 6 is a fixed shaft, which is fixed by welding, and the end of the fixed shaft is directly fixed to the connecting block 11, and the connecting block 11 can only slide up and down between the two folding plates 8.

[0032] A guide column 9 is fixedly connected to the lower end of the connecting block 11, and the guide column 9 penetrates downwardly through the folding plate 8 located below. The setting of the guide column 9 ensures the consistency of the direction of the connecting block 11 sliding up and down. A first spring 10 is sleeved on the guide column 9. The setting of the first spring 10 is to keep the guide column 9 in an upper state. The folding plate 8 located above is threadedly connected to the adjusting bolt 12, and the lower end of the adjusting bolt 12 is against the upper end of the connecting block 11. When it is necessary to adjust the height of the second scraper 6, the adjusting bolt 12 is rotated to compress or release the first spring 10, that is, the connecting block 11 descends or rises, thereby realizing the adjustment of the height position of the second scraper 6. It should be noted that when adjusting, the fixing bolts 12 at both ends of the second scraper 6 need to be rotated at the same time.
