Abstract
Description
Technical Field
[0001] This utility model relates to the field of proton exchange membrane processing technology, and specifically to a proton exchange membrane processing coating device. Background Technology
[0002] The proton exchange membrane processing and coating device mainly involves the manufacturing process of proton exchange membrane fuel cells. The proton exchange membrane is an important component of fuel cells, used to transfer hydrogen protons through the electrolyte layer to realize the electrochemical reaction of hydrogen and oxygen to generate electricity.
[0003] Chinese Patent CN221558876U discloses a proton exchange membrane (PEM) coating device. The PEM coating device includes: a coating roller; an air inlet duct fixedly installed at the upper end of a dust removal plate; a dust collector fixedly installed at the lower end of the air inlet duct; a fan impeller inside the dust collector; one end of the fan impeller fixedly installed on a rotary motor; and an exhaust duct at the bottom of the dust collector. By using a dust collector, dust particles and impurities in the working environment can be removed from the PEM surface, effectively reducing the amount of dust particles and impurities falling onto the PEM surface. This prevents uneven coating distribution caused by dust particles and impurities, resulting in unevenness, cracks, or voids on the PEM surface, thus affecting the membrane's performance and stability.
[0004] However, in the above technical solution, the dust collector alone can remove dust particles and impurities from the working environment onto the surface of the proton exchange membrane. This can effectively reduce the amount of dust particles and impurities falling onto the surface of the proton exchange membrane. However, this device cannot remove oil stains and other adhering impurities from the surface of the proton exchange membrane, which leads to a decline in the quality of subsequent processing.

[0020] Example 1
[0021] like Figures 1-5 As shown, the present invention proposes a proton exchange membrane processing and coating device, which is installed on the main body of a coating machine and includes a conveying roller 1, a coating die head 2, and a cleaning component. Multiple conveying rollers 1 are distributed, and both ends of the conveying rollers 1 are connected to the main body of the coating machine. The proton exchange membrane is wound on the conveying rollers 1. Two coating dies 2 are symmetrically arranged vertically and connected to the main body of the coating machine. The main body of the coating machine is also equipped with a drying device, through which the proton exchange membrane passes.
[0022] There are two cleaning components. The cleaning components are connected to the main body of the coating machine and are respectively set on both sides of the proton exchange membrane. The cleaning components include a cleaning roller 3, a sponge roller 4, a transmission component 5 and a liquid storage tank 6. The two ends of the cleaning roller 3 are rotatably connected to the main body of the coating machine. The sponge roller 4 is in contact with the cleaning roller 3. The transmission component 5 is connected to the sponge roller 4 and the cleaning roller 3.
[0023] In an optional embodiment, the transmission component 5 includes a first gear 17 and a second gear 18, and two of each are provided. The first gear 17 and the second gear 18 are respectively connected to the two ends of the cleaning roller 3 and the sponge roller 4, and the first gear 17 and the second gear 18 are meshed and connected for transmission.
[0024] The two ends of the sponge roller 4 are connected to the main body of the coating machine, and the two ends of the liquid storage tank 6 are connected to the main body of the coating machine. The liquid storage tank 6 has a notch for accommodating the sponge roller 4. The rotation of the cleaning roller 3 drives the sponge roller 4 to rotate synchronously through the transmission component 5. The cleaning liquid is transferred through the sponge roller 4 and coated on the cleaning roller 3 to clean the proton exchange membrane.
[0025] Example 2
[0026] like Figures 2-5 As shown, the proton exchange membrane processing coating device proposed in this utility model has a more detailed structure than that in Embodiment 1. The cleaning component further includes a driving device 7 and a cleaning component. The driving device 7 is connected to the main body of the coating machine, and the output end of the driving device 7 is connected to any end of the cleaning roller 3. The driving device 7 is selected from, but is not limited to, a motor. The cleaning component is connected to the main body of the coating machine and is in contact with the cleaning roller 3. When the cleaning component is in use, the cleaning component and the cleaning roller 3 scrape each other to remove the cleaning liquid contaminating their surfaces.
[0027] The cleaning assembly includes a fixed frame 8, a cleaning scraper 9, an elastic element 10, a recycling bin 11, and a filter element 12. The fixed frame 8 is connected to the main body of the coating machine at both ends. The fixed frame 8 has notches. The cleaning scraper 9 is slidably connected in the notches on the fixed frame 8. The cleaning scraper 9 is in contact with the surface of the cleaning roller 3.
[0028] In an optional embodiment, the fixing frame 8 is provided with symmetrical guide grooves 15, and the cleaning scraper 9 is connected to guide blocks 16 on both sides, which are slidably connected to the guide grooves 15; the sliding of the guide blocks 16 in the guide grooves 15 can guide the movement direction of the cleaning scraper 9 and prevent the angle from changing.
[0029] Multiple elastic elements 10 are distributed, and the two ends of the elastic elements 10 are connected to the cleaning scraper 9 and the fixing frame 8 respectively. The elastic elements 10 are spring plates, or the spring plates 10 can be replaced with ordinary springs. The recycling box 11 is connected to the main body of the coating machine. The recycling box 11 has a notch for the cleaning scraper 9 to pass through, and the filter element 12 is connected inside the recycling box 11.
[0030] In an optional embodiment, the filter element 12 consists of a first filter screen 13 and a second filter screen 14, which are arranged parallel to each other vertically. The mesh size of the first filter screen 13 is larger than that of the second filter screen 14. Through multi-layer filtration, particulate matter in the liquid is removed, reducing the number of steps in liquid recycling or processing.
[0031] In summary, when this utility model is used, the coated proton exchange membrane is wound around the conveying roller for conveying. During conveying, it comes into contact with the cleaning components on both sides. The drive device 7 drives the cleaning roller 3 to rotate. The cleaning roller 3 meshes with the second gear 18 on the sponge roller 4 through the rotation of the first gear 17. The two rotate synchronously. When the sponge roller 4 rotates, it comes into contact with the cleaning roller 3, and the cleaning solution adhering to its surface is transferred to the cleaning roller 3. The cleaning roller 3 contacts the proton exchange membrane for cleaning. The cleaning scraper 9 continuously keeps in contact with the cleaning roller 3 to remove the contaminated cleaning solution and oil adhering to its surface and guides it into the recovery box 11 through its own angle. It is then filtered by the filter element 12 to reduce impurities in the liquid and facilitate subsequent centralized processing. After both sides of the proton exchange membrane are cleaned, it enters the coating die head for coating operation. Then, the proton exchange membrane passes through the drying equipment on the main body of the coating machine for drying.
[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
