Description

Technical Field

[0001] The present application relates to the field of membrane manufacturing equipment, and in particular to a membrane manufacturing device for an anion exchange membrane. Background Art

[0002] In recent years, with the growing global demand for sustainable energy and environmentally friendly materials, the use of anion exchange membrane (AEM) membrane electrode technology to achieve electrochemical reduction of carbon dioxide to produce aviation fuel and high-quality chemicals has become a research hotspot for scientific research institutions and universities. As a key component of this technology, the performance of anion exchange membranes directly impacts the quality of the final product and the efficiency of the reaction.

[0003] Currently, the main methods for preparing anion exchange membranes include cast film and scraped film. The cast film method, due to its ease of operation and low cost, is more suitable for small-scale membrane production in R&D laboratories. The scraped film method, on the other hand, is more suitable for large-scale industrial production due to its ability to achieve continuous production.

[0004] In a laboratory setting, the tape casting method typically involves pouring a membrane solution into glassware such as a watch glass or tray and allowing the solvent to evaporate naturally to prepare anion exchange membranes. To achieve high-performance anion exchange membranes, researchers often use volatile organic solvents to prepare the membrane solution. Furthermore, a heating table may be required during the membrane production process to accelerate solvent evaporation, resulting in a dry, smooth membrane sheet.

[0005] Although the tape casting method has shown many advantages in laboratory membrane production, it still has some significant limitations in practical applications. In particular, because the membrane production process is highly dependent on the size and shape of the glassware used, such as watch glasses and trays, it is difficult to accurately control the size and shape of the prepared membrane. This limitation is particularly evident when it is necessary to prepare membrane sheets of specific sizes. It is difficult to flexibly adjust the physical properties of the membrane to meet the needs of different application scenarios. This limitation also reduces the preparation efficiency of anion exchange membranes. Therefore, the development of a new membrane production device that can overcome the above limitations is of great significance for promoting the application and development of anion exchange membranes.

[0027] The following is combined with Figure 1-6 This application is described in further detail.

[0028] The present application discloses a film-making device for an anion exchange membrane. Figure 1 and Figure 2A film-making device for an anion exchange membrane includes a heating platform 1, a tape holder 3, a tape roll 4 and a light positioning component 8. The tape holder 3, the tape roll 4 and the light positioning component 8 are all located on the operating table of the heating platform 1. The tape roll 4 is rotatably mounted on the tape holder 3. The tape holder 3 is provided with a pressure wheel 7 near the free end 41 of the tape roll 4. The light positioning component 8 is located between the heating platform 1 and the tape holder 3. According to the shape and size of the anion exchange membrane to be prepared, the light positioning component 8 is adjusted. The light positioning component 8 guides the tape holder 3 to move along a straight line with the tape roll 4, and then the free end 41 of the tape roll 4 is pasted to the starting position of the heating platform 1. The tape holder 3 is moved, and the tape roll 4 releases the tape and continues to stick to the heating platform 1. Then the direction is changed and the sticking is continued until the tape is enclosed into the required membrane shape. Refer to Figure 3 The groove in the area enclosed by the tape is the membrane forming area 2. The membrane solution is poured into the membrane forming area 2, and the heating platform 1 is started for drying to prepare the anion exchange membrane, thereby achieving the purpose of flexibly adjusting the size and shape of the membrane during preparation to meet the needs of different application scenarios.

[0029] Reference Figure 1 and Figure 3 , the shape of the film-making area 2 is not limited to the rectangle shown in the embodiment, and other polygonal designs can also be adopted, such as pentagons, hexagons, etc. Specifically, the geometric shape of the film-making area 2 and the specific dimensions of its sides can be flexibly adjusted according to actual application requirements to adapt to the use requirements in different scenarios; the tape roll 4 used to form the film-making area 2 provides a variety of different tape thickness specifications for selection, and the preferred tape thickness range is 30 to 70 microns. By selecting tapes of different thicknesses, the final thickness of the anion exchange membrane product formed in the film-making area 2 can be effectively controlled. It is worth mentioning that this method also allows multiple layers of tape to be stacked and pasted together, so as to accurately adjust the depth of the groove in this way, thereby achieving more precise control of the film thickness. Grooves of different shapes, lengths and depths are obtained by pasting and enclosing with tape, and then volatilizing after adding slurry to obtain membrane products of different shapes. This method is not only simple to operate, but also can meet diverse product design requirements, greatly improving production efficiency and flexibility.

[0030] Reference Figure 1 and Figure 4 The tape holder 3 is horizontally arranged on the heating table 1, and its design is divided into a front end and a rear end along the moving direction, the front end is closer to the forward moving direction of the tape holder 3, and the rear end is closer to the free end 41 of the tape roll 4; the front end oblique beam position of the tape holder 3 is fixedly provided with a clamping member 31, the clamping member 31 is arranged on both sides of the tape roll 4, the clamping member 31 is arranged vertically, the bottom end of the clamping member 31 is an inclined surface and is fixedly fitted with the front end oblique beam of the tape holder 3, the top end of the clamping member 31 is bent and extended toward the front end of the tape holder 3, and a gap is left between the top end of the clamping member 31 and the front end oblique beam of the tape holder 3 for cooperating with the tape roll 4; refer to Figure 5 A cutter 33 is fixedly provided on the top of the rear end of the tape holder 3. The cutter 33 is tilted away from the tape roll 4, which can quickly cut the tape and ensure that the cutting surface of the tape is flat.

[0031] Reference Figure 2 A tape sensor 32 is fixedly embedded in the middle position of the tape holder 3. The detection port of the tape sensor 32 is aligned with the tape release portion 42 of the tape roll 4. The tape sensor 32 is used to detect whether the tape on the tape roll 4 is exhausted. The tape sensor 32 is also electrically connected to an alarm. When the tape sensor 32 detects that the tape is exhausted, it sends a high-level signal to the alarm, and the alarm is activated to remind the operator.

[0032] Reference Figure 4 The pressure roller 7 is a horizontal cylindrical roller. The bottom end of the pressure roller 7 contacts the top of the tape attached to the heating table 1. A support frame is provided between the pressure roller 7 and the tape holder 3. The support frame is arranged horizontally and passes through the pressure roller 7. Both ends of the support frame are fixed to the tape holder 3. The roller 34 can be made of rubber material with a certain degree of elasticity. When the tape holder 3 moves, the pressure roller 7 rolls along the top of the tape attached to the heating table 1, compacting the tape to prevent the tape from being loosely attached and effectively reducing wrinkles and bubbles during the tape application process.

[0033] Reference Figure 1 and Figure 4 The bottom end of the tape holder 3 is fixedly connected to a roller 34, and four rollers 34 are provided. The four rollers 34 are distributed at the four corners of the bottom end of the tape holder 3, and the rollers 34 are in rolling connection with the operating table of the heating platform 1; in order to better cooperate with the intelligent work of the optical positioning component 8, an electric motor 35 is fixedly connected to the roller 34 of the tape holder 3, and the electric motor 35 drives the roller 34 to roll forward along the heating platform 1; at the same time, a movable measuring part 5 is also fixedly provided on the roller 34. The movable measuring part 5 includes an encoder and a counter. The encoder is installed on the roller 34 shaft, and the length of the tape is measured by the rotation of the roller 34. The movable measuring part 5 is electrically connected to the electric motor 35, so that when the preset pasting length of the tape is reached, the electric motor 35 will drive the tape holder 3 to automatically stop moving, thereby completing the tape pasting of one side length in the polygon, and then the tape is cut by the cutter 33, which improves the convenience of the entire operation.

[0034] Reference Figure 2The tape holder 3 is provided with a plurality of independent slots, each of which can accommodate a roll of tape of different thickness. In this embodiment, three rolls of tape 4 are provided, and each tape roll 4 corresponds to a different thickness, such as 30 microns, 50 microns, and 70 microns. Carrying three rolls of tape 4 at the same time can support the operator to quickly switch tapes of different thicknesses as needed, without the need to frequently replace the tape roll 4, saving time and energy; the three rolls of tape are neatly arranged along the moving direction of the tape holder 3, and the rotation axes of the three rolls of tape 4 coincide and are perpendicular to the moving direction of the tape holder 3. The ends of the tape rolls 4 on both sides are inserted into the gaps of the clamps 31 and are clamped with the clamps 31, which is convenient for the later disassembly and replacement of the tape roll 4; select the tape roll 4 of the required thickness, pass the free end 41 of the tape roll 4 over the cutter 33 at the front end of the tape holder 3, and then pass through the gap between the bottom end of the pressure wheel 7 and the heating table 1 and then stick it on the heating table 1.

[0035] When stacking double-layer tapes, in order to facilitate the switching of tapes of different thicknesses and reduce the influence of the weight of the pressure wheel 7 on the overall device, the pressure wheel 7 is slidably connected to the outer wall of the support rod 71. Figure 5 A locking piece 72 is provided between the pressure wheel 7 and the support rod 71. One end of the locking piece 72 passes through the pressure wheel 7 and abuts against the outer surface of the support rod 71. The locking piece 72 is threadedly connected to the pressure wheel 7, and the locking piece 72 is used to lock the position of the pressure wheel 7 on the support rod 71.

[0036] Reference Figure 1 and Figure 2 The optical positioning component 8 includes a light emitter 81, a light receiver 82 and a controller. The light emitter 81 can be detachably fixed to the operating table of the heating table 1, and the light receiver 82 is fixed to the window slot position of the tape holder 3. The light emitter 81 and the light receiver 82 are located at the same height. The light emitter 81 will emit one or more grating lines. The multi-line grating can provide higher accuracy. The light receiver 82 receives the grating lines; when the bottom of the tape holder 3 moves, if an offset occurs, the grating lines will be blocked. After the receiver detects the blocking signal, it will feed the information back to the controller. The controller adjusts the speed and direction of the electric motor 35 according to the received blocking signal to make the tape holder 3 return to the correct path.

[0037] To indicate alignment of the light emitter 81 and the light receiver 82, refer to Figure 2 and Figure 6An angle plate 6 is also provided on the tape holder 3. The angle plate 6 is fixed horizontally in the window slot position of the tape holder 3. The angle plate 6 is close to the bottom of the light receiver 82. The angle plate 6 is made of a transparent material with scale lines. When the grating line covers 90° or 270° of the angle plate 6, the installation position of the light emitter 81 and the light receiver 82 is correct; at the same time, when replacing different tape pasting edges, first remove the light emitter 81 and move it to the position corresponding to the required direction of the subsequent tape pasting edge, install the light emitter 81 again, and use the angle plate 6 to adjust the emitted grating line to the required angle, which is the angle between the two side lengths of the film forming area 2. Then rotate the tape holder 3 so that the light receiver 82 is aligned with the light emitter 81 again, and then repeat the above operation until the film forming area 2 is closed.

[0038] In addition, the optical positioning component 8 can also be replaced by a combination of a pen and a ruler, and the shape of the required film-forming area 2 can be specifically marked on the heating table 1 using the pen and the ruler.

[0039] The implementation principle of the film-making device of an anion exchange membrane in the embodiment of the present application is as follows: when preparing the anion exchange membrane, first install the light emitter 81 according to the required film shape and start it, pass the free end 41 of the tape roll 4 of the required thickness through the cutter 33 and the pressure wheel 7 position and stick it to the starting position of the film-making area 2 on the heating table 1, then start the electric motor 35 to drive the roller 34 to drive the tape holder 3 to move along the grating line direction as a whole. During the movement, the tape continues to stick to the heating table 1. When the mobile measuring part 5 detects that the tape holder 3 moves to the tape When the preset pasting length is reached, the electric motor 35 will drive the tape holder 3 to automatically stop moving, thereby completing the tape pasting of one side of the polygon, and then the tape is cut using the cutter 33; thereafter, the light emitter 81 is removed and reinstalled to align with the second side of the film forming area 2, and then the tape holder 3 is rotated so that the light receiver 82 is aligned with the light emitter 81 again, and then the above operation is repeated until the film forming area 2 is closed; if two layers of tape need to be stacked, first align the inner edge of the second layer of tape with the inner edge of the pasted tape, and then repeat all the operations for the first layer.

[0040] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
