Description

Technical Field

[0001] This utility model relates to the field of proton exchange membrane production technology, and in particular to continuous proton exchange membrane production equipment. Background Technology

[0002] In the industrial production of proton exchange membranes (typically represented by perfluorosulfonic acid membranes), a complete and continuous production process is formed, consisting of material synthesis, film modification, heat treatment, and winding and shaping. Material synthesis involves preparing the core resin through specific chemical reactions, providing the chemical basis for proton conductivity. In the film modification stage, casting and extrusion processes are used to shape the membrane, and sulfonation, crosslinking, and doping are employed to impart good proton conductivity and chemical stability. Heat treatment, as a crucial "chemical shaping" process, promotes the rearrangement of molecular chains within the membrane at high temperatures, effectively eliminating internal stress, optimizing the crystal structure, and enabling the membrane to reach its ideal performance state. Finally, winding and shaping transforms the membrane into a finished product suitable for membrane electrode assembly.

[0003] In the existing technology, during the continuous production of proton exchange membranes, the high-temperature membrane after heat treatment directly enters the winding process. Traditional winding devices generally adopt a single roller drive mode. Due to the lack of effective temperature transition control, the ordered structure of the molecular chain of the high-temperature membrane is destroyed during the rapid cooling process, the crystallinity rises abnormally, and the internal stress re-accumulates, which in turn causes problems such as membrane deformation and cracking. This greatly reduces the dimensional stability and chemical durability of the membrane, affecting its service life in fuel cells. Utility Model Content

[0004] The purpose of this invention is to provide a continuous proton exchange membrane production equipment to address the aforementioned shortcomings in the prior art.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] like Figure 1-6 As shown, this utility model provides a continuous proton exchange membrane production equipment, including a frame 1, a conveying and guiding mechanism 2, and a membrane hot air heating mechanism 3. The frame 1 is equipped with a drive motor 12 and a winding roller 11 connected to the drive motor 12. The conveying and guiding mechanism 2 includes an upper guide roller assembly 21 and a lower guide roller assembly 22 arranged in parallel. The upper guide roller assembly 21 is located in the upper mounting area of ​​the frame 1, and the lower guide roller assembly 22 is located in the lower mounting area of ​​the frame 1. The upper guide roller assembly 21 and the lower guide roller assembly 22 are arranged vertically in layers. The membrane 5 to be wound is conveyed along the lower guide roller assembly 22 and the upper guide roller assembly 21 to the winding roller assembly. On the take-up roller 11, the heating air heater 31 structure includes an air heater 31, an air supply pipe 33, and a hot air conveyor 34. The air heater 31 is located on one side of the frame 1, and the hot air conveyor 34 is located inside the frame 1. The hot air conveyor 34 is connected to the air heater 31 through the air supply pipe 33. The bottom of the hot air conveyor 34 is provided with a bottom air outlet structure 35, the side of the hot air conveyor 34 is provided with a side air outlet structure 36, and the top of the hot air conveyor 34 is provided with a top air outlet structure 37. The bottom air outlet structure 35, the side air outlet structure 36, and the top air outlet structure 37 correspond to different directions of the film 5 being conveyed along the frame 1.

[0027] Specifically, the frame 1 is installed on the proton exchange membrane production line to wind up the heat-treated high-temperature membrane 5. The frame 1 includes a bottom frame and two side plates on the bottom frame, which are connected by a connecting beam. A winding roller 11, an upper guide roller assembly 21, and a lower guide roller assembly 22 are installed on the frame 1. The winding roller 11 is located on one side of the upper part of the frame 1. A drive motor 12 connected to the winding roller 11 is installed on the frame 1. The winding roller 11 can rotate under the drive of the drive motor 12, thereby realizing... For the winding of the film 5, the upper guide roller assembly 21 and the winding roller 11 are set at the same height. The upper guide roller assembly 21 includes at least one upper guide roller. The lower guide roller assembly 22 is set directly below the upper guide roller assembly 21 and the winding roller 11.

Thus, the conveying of the film 5 on the frame 1 forms a bottom conveying section, a side conveying section, and a top conveying section. The top conveying section and the bottom conveying section are parallel, thereby increasing the conveying distance of the film 5 on the frame 1, so that the film 5 can gradually cool down.

[0028] In this embodiment, the membrane hot air heating mechanism 3 includes a fan 32, an air heater 31, an air supply pipe 33, and a hot air conveyor 34. The air heater 31 is disposed on one side of the frame 1, and the fan 32 is connected to the air heater 31. The hot air conveyor 34 is disposed inside the frame 1 along the vertical direction.

One end of the air supply pipe 33 is connected to the air heater 31, and the other end is connected to the hot air conveyor 34. The air heater 31 can heat the air to provide hot air, which is then delivered to the hot air conveyor 34 through the air supply pipe 33. The air heater 31 and the fan 32 are existing technologies and will not be described in detail. The hot air conveyor 34 is a rectangular conveying component. Its hollow interior forms an air delivery chamber. A bottom air outlet structure 35 is located at the bottom of the hot air conveyor 34, corresponding to the bottom conveying section of the membrane 5. A side air outlet structure 36 is located on the side of the hot air conveyor 34, corresponding to the side conveying section of the membrane 5.

The distance between the bottom air outlet structure 35, the side air outlet structure 36, and the top air outlet structure 37 and the membrane 5 is greater than 5 cm. During use, the bottom air outlet structure 35 is open, while the side air outlet structures 36 and the top air outlet structure 37 can be controlled according to the actual temperature and conveying speed of the membrane 5. A temperature sensor is installed on the frame 1 to monitor the surface temperature of the membrane 5 in real time. When the temperature of the membrane 5 drops rapidly, the side air outlet structure 36 and / or the top air outlet structure 37 can be opened to increase the hot air coverage area. When the temperature of the membrane 5 is close to the target temperature range, the top air outlet structure 37 or the side air outlet structure 36 can be closed to avoid overheating.

It is then wound onto the take-up roller 11 at a stable angle. During the transport process, the air heater 31 sends heated air into the hot air conveyor 34. The hot air is evenly covered on the surface of the membrane 5 through the bottom air outlet structure 35, the side air outlet structure 36, and the top air outlet structure 37, which prolongs the heat treatment effect, allowing the membrane 5 to cool down slowly and be wound up at a suitable temperature, effectively avoiding problems such as membrane deformation and cracking.
