Technical Field
[0001] The utility model relates to the field of ion exchange membranes, in particular to an ion exchange membrane structure and a salt conversion device therefor. Background Art
[0002] Ion exchange membranes are a special type of thin film whose main function is to transport ions in electrochemical devices. They are commonly used in applications such as batteries, fuel cells, and electrolyzers. These membranes play a key role in electrochemical processes by selectively allowing specific types of ions to pass through while blocking the transfer of other ions. Ion exchange membranes have a wide range of uses in the fields of chemical engineering and energy. Their main function is to transport ions in electrochemical devices to achieve specific chemical reactions or energy conversion processes.
[0003] However, most of the current ion exchange membrane structures and their use in salt conversion devices have the following problems:
[0004] With the existing ion exchange membrane structure and its use in salt conversion devices, the ion exchange membrane is prone to wrinkles when in use or when being installed, resulting in insufficient sealing and poor stability during use due to gaps, making it inconvenient to conveniently flatten and seal the ion exchange membrane in use; at the same time, the membrane resistance of the ion exchange membrane increases, and the swelling of the membrane will also increase and produce ripples when in contact with the electrolyte. If ripples are produced, electrolyte leakage will occur when the ion exchange membrane is used for electrolysis or electrodialysis.
[0005] Therefore, we have made improvements to this and proposed an ion exchange membrane structure and a salt conversion device. Summary of the invention
[0006] The utility model aims to solve the inconvenience of flattening and sealing the ion exchange membrane in use at present, and the problems such as leakage of electrolyte may occur when electrolysis and electrodialysis are carried out.
[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:
[0008] Ion exchange membrane structure is used to improve the above problems.
[0009] The specific application is as follows:
[0010] It includes a liquid storage box, a slider is slidably connected to the upper limit of the liquid storage box, a mounting frame is fixedly connected to the slider, a baffle is bolted to the mounting frame, a rotating member is rotatably connected to the baffle, a first bevel gear is fixedly connected to the rotating member, the first bevel gear is meshingly connected to the second bevel gear, the second bevel gear is fixedly connected to a threaded rod, the threaded rod is rotatably connected in the baffle, a moving block is threadedly connected to the threaded rod, a spring is fixedly connected to the moving block, the other end of the spring is fixedly connected to a pressure plate, a guide frame is fixedly connected to the pressure plate, the guide frame is limited and slidably connected to the moving block, and an ion exchange membrane is arranged on the mounting frame.

[0014] As a preferred technical solution of the present application, the sliders are symmetrically distributed on the left and right sides of the mounting frame.
[0015] As a preferred technical solution of the present application, the second bevel gears are symmetrically distributed on the left and right sides of the first bevel gear, and the second bevel gears correspond one-to-one with the moving blocks through threaded rods.
[0016] As a preferred technical solution of the present application, one end of the threaded rod is fixedly connected to the center of one side of the second bevel gear.

[0020] Compared with the prior art, the utility model has the following beneficial effects:
[0021] In the scheme of this application:
[0022] 1. Through the provided threaded rod, when the ion exchange membrane is installed and used, the ion exchange membrane can be installed on the mounting frame, and the baffle plate can be installed on the mounting frame. At the same time, the pressure plate on the baffle plate presses the ion exchange membrane under the push of the spring. When the ion exchange membrane needs to be flattened, the rotating member can be rotated to drive the first bevel gear to rotate. When the first bevel gear rotates, the threaded rod can be driven to rotate through the second bevel gear. When the threaded rod rotates, it can drive the moving block to move smoothly. When the moving blocks on both sides move outward at the same time, the moving blocks can drive the pressure plate to move through the guide frame. When the pressure plates on both sides move outward at the same time, the pressed ion exchange membrane can be flattened to avoid wrinkles affecting the stability of use.
[0023] 2. By setting up the ion exchange membrane, a non-woven fabric sheet having a dense fine fiber layer as an intermediate layer is used, and the non-woven fabric sheet is stacked on a non-woven fabric sheet coated with an ion exchange resin, and then dried to form an ion exchange resin coating. The ion exchange resin coating penetrates into the interface between the long fiber layer and the fine fiber layer. However, as long as a sufficient anchoring effect can be obtained, the target strength and dimensional stability can be ensured, thereby solving the problems of swelling of the ion exchange membrane and generation of corrugations when in contact with the electrolyte.

Example
[0039] The solution in Example 1 is further introduced below in combination with a specific working method, as described below:
[0040] like Figure 8 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the ion exchange membrane 13 includes a non-woven fabric sheet 1301, an ion exchange resin coating 1302 is provided on the non-woven fabric sheet 1301, a fine fiber layer 1303 is installed on the ion exchange resin coating 1302, and a long fiber layer 1304 is installed on the fine fiber layer 1303, which can ensure that the use of the ion exchange membrane 13 can avoid leakage of electrolyte during electrolysis and electrodialysis.
[0041] like Figure 3 As shown, as a preferred embodiment, on the basis of the above-mentioned method, further, the cross section of the slider 2 is "T"-shaped, which can ensure that the "T"-shaped slider 2 can slide smoothly within the liquid storage box 1 within a limited position.

However, as long as a sufficient anchoring effect can be obtained, the target strength and dimensional stability can be ensured, thereby solving the problem of swelling and corrugation of the ion exchange membrane 13 when in contact with the electrolyte. The ion exchange membrane 13 can be used for desalination and ion separation in water treatment processes, such as reverse osmosis desalination, ion exchange chromatography, etc., by selectively allowing specific ions to pass through the ion exchange membrane 13 to achieve water purification and ion separation.
