Description

Technical Field

[0001] This utility model relates to the field of proton exchange membrane processing technology, and in particular to a hot-pressing and cooling device for the preparation of proton exchange membranes. Background Technology

[0002] The proton exchange membrane (PEM) is the core component of a proton exchange membrane fuel cell (PEMFC) and plays a crucial role in its performance. The PEM has two main functions in a fuel cell: firstly, it provides a channel for proton migration and transport, allowing protons to pass through the membrane from the anode to the cathode, forming a loop with electron transfer in the external circuit to provide current. Therefore, the performance of the PEM is extremely important to the fuel cell's performance, directly affecting its lifespan; secondly, it acts as a separator to isolate the reactant gases at the anode and cathode.

[0003] Chinese Patent CN220390401U discloses a hot-pressing and cooling device for preparing proton exchange membranes, including a processing shell. Both sides of the outer wall of the processing shell are provided with receiving racks for winding and placing the proton exchange membrane. Inside the processing shell is a hot-pressing and cooling assembly for processing the proton exchange membrane. The hot-pressing and cooling assembly includes a hot-pressing component and a cooling component. The hot-pressing component is located on one side of the inner wall of the processing shell, and the cooling component is located on the inner wall of the processing shell, away from the hot-pressing component. As can be seen from the above, this invention allows the temperature of the proton exchange membrane to be increased or decreased by hot or cold air before hot-pressing and cooling, thereby avoiding sudden temperature rises or drops and preventing any impact on the physical properties of the proton exchange membrane during the hot-pressing and cooling process.

[0004] Existing hot-press cooling devices for proton exchange membrane preparation transport the exchange membrane through receiving racks on both sides. However, the winding or unwinding speed of the receiving racks is not easy to control, resulting in poor matching with the speed of hot-press cooling. This leads to downtime during production, causing the machine to stop while waiting for the receiving racks to finish winding, thus reducing the efficiency of proton exchange membrane preparation and the effectiveness of the hot-press cooling device.

[0027] Example 1

[0028] like Figure 1 - Figure 3As shown, the present invention proposes a hot-pressing and cooling device for preparing a proton exchange membrane, comprising: a base plate 1, two sets of take-up and release components 2, a proton exchange membrane preparation component, and a support rod 4; connecting plates 101 are respectively connected to both sides of the base plate 1, and the connecting plates 101 are respectively provided with mounting grooves 102; the take-up and release components 2 are connected to the connecting plates 101; the take-up and release components 2 include a fixed plate 201, a counterweight 202, a handle 203, a fixing frame 204, a motor 205, a take-up and release roller 206, a connector, and a frequency converter 213; the counterweight 202 is connected below the fixed plate 201 and above it. Handles 203 are connected to both ends, and counterweights 202 are connected to the mounting groove 102 and are detachably connected. A fixing frame 204 is connected to a fixing plate 201, and a motor 205 is connected to the fixing frame 204. The motor 205 drives the take-up and unwind rollers 206 and is electrically connected to a frequency converter 213. The proton exchange membrane preparation assembly is connected to the base plate 1 via a support rod 4. Four take-up and unwind assemblies 2 are provided and divided into two groups. The two groups of take-up and unwind assemblies 2 correspond to the feed inlets of the proton exchange membrane preparation assembly, and each group of take-up and unwind assemblies 2 consists of two components that can be used alternately for take-up or unwinding. By using the two groups of take-up and unwind assemblies 2 alternately for take-up or unwinding, the production efficiency of proton exchange membrane preparation is conveniently improved, and the use of the hot-pressing and cooling device for proton exchange membrane preparation is enhanced.

[0029] Further explanation: The connecting components include a connecting frame 207, a mounting plate 208, a bracket 209, a film-drawing roller 210, a support 211, and a mounting block 212; the connecting frame 207 is connected to the fixed plate 201 and is connected to the take-up and untake-down roller 206; both ends of the mounting plate 208 are connected to the connecting frame 207 and the fixed frame 204 respectively, and are detachably connected; the mounting plate 208 is connected to the bracket 209, and the bracket 209 is connected to the film-drawing roller 210; the support 211 is connected to one side of the fixed frame 204, and the support 211 is connected to the mounting block 212; the mounting block 212 is connected to the frequency converter 213. A pre-drilled connection hole b is provided below the connecting frame 207. The fixing plate 201 and the connecting frame 207 are respectively provided with pre-drilled mounting holes b at their connection positions. Screws are used to connect the connecting frame 207 and the fixing plate 201 through the threaded connection hole b and the pre-drilled mounting hole b, which facilitates the disassembly and reassembly of the connecting frame 207 and the fixing plate 201. This allows for the easy connection or disassembly of the proton exchange membrane roll and the take-up roller 206. In this way, the take-up roller 206 and the connecting frame 207 can be detachably connected. A pin hole is provided on the connecting frame 207, and a connecting lug with a pin hole is provided at the end of the take-up roller 206. The operator inserts the pin into the pin hole of both, and then uses a cotter pin or other limiting device to prevent the pin from falling off. When disassembly is required, the limiting device is removed and the pin is pulled out.

[0030] To further explain, the support 211 is provided with a reserved connection hole a, and the mounting block 212 is provided with a reserved mounting hole a. A screw is threaded through the reserved connection hole a and threadedly connected to the reserved mounting hole a, for detachable connection between the mounting block 212 and the support 211. The assembly and disassembly of the support 211 and the mounting block 212 are the same as those of the fixing plate 201 and the connecting frame 207, which facilitates improved assembly and disassembly efficiency and enhances the connection and use of the components of the retractable assembly 2.

[0031] Example 2

[0032] like Figure 1 As shown, the present invention proposes a hot-pressing and cooling device for the preparation of proton exchange membranes. Based on the above embodiments, this embodiment also details the specific components of the proton exchange membrane preparation assembly and their arrangement.

[0033] To further explain, the proton exchange membrane preparation assembly includes a processing shell 3, a hollow chamber 301, a water chiller 302, and a water storage tank 303; a support rod 4 is connected to the bottom of the processing shell 3, and material inlets are respectively provided at both ends of the processing shell 3; the hollow chamber 301, the water chiller 302, and the water storage tank 303 are connected to the top of the processing shell 3; the hollow chamber 301 is connected to a hot pressing component, the water storage tank 303 is connected to a cooling component, and a partition is connected to the inner wall of the processing shell 3. The inner wall of the processing shell 3 is divided into a hot pressing chamber and a cooling chamber by a partition, and the partition is provided with through holes for transporting the proton exchange membrane onto the overall hot pressing and cooling device. The components of the proton exchange membrane preparation component processing shell 3, such as the hot pressing component and the cooling component, are all existing publicly available technologies, so they will not be described in detail. Instead, two sets of take-up and unwinding components 2 are used in conjunction with the unwinding and rewinding of the proton exchange membrane preparation component to avoid the problem of discontinuity of the proton exchange membrane and machine stoppage caused by the take-up and unwinding components 2. The take-up and unwinding components 2 are used alternately to improve the production efficiency of the proton exchange membrane and improve the practicality of the hot pressing and cooling device for proton exchange membrane preparation.

[0034] The working principle of this utility model is as follows: When using the hot-pressing and cooling device for proton exchange membrane preparation, the material inlets at both ends of the processing shell 3 are first connected to the take-up and unwrap assembly 2. The take-up and unwrap assembly 2 uses the take-up and unwrap rollers 206 to unwind and wind the proton exchange membrane. The take-up and unwrap rollers 206 are driven to rotate by the motor 205. The motor 205 is electrically connected to the frequency converter 213. The frequency converter 213 adjusts the speed of the motor 205 by changing the power supply frequency and voltage of the motor 205. During the unwinding and winding process, the frequency converter 213 is used to facilitate real-time adjustment of the speed of the motor 205 to keep the linear velocity and tension of the material constant. Furthermore, the take-up and unwrap assembly 2 is provided with four components, which are connected in pairs to the material inlets at both ends of the processing shell 3, so that the material inlets at both ends of the processing shell 3 are cooperating with the unwinding and winding. When component 2 is about to be used up, the operator prepares the other two take-up and release components 2. After the take-up and release component 2 is finished, the operator disassembles it from the connecting plate 101 using handle 203. Then, the operator operates the handles 203 of the other two take-up and release components 2 to lift the take-up and release component 2 and connect the counterweight 202 to the mounting slot 102. When the take-up and release components 2 at both ends of the processing housing 3 are replaced alternately, the operator operates to replace the take-up and release components 2 at both ends of the processing housing 3, which facilitates the replacement efficiency of the take-up and release components 2. The replaced take-up and release components 2 continue to be connected and used in conjunction with the proton exchange membrane preparation component, which helps to reduce downtime, improve production efficiency, and facilitates a tighter connection of the overall components of the hot-pressing and cooling device for proton exchange membrane preparation.

[0035] 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.
