Description

Technical Field

[0001] The utility model relates to the field of ion exchange membrane processing, in particular to a drying oven for ion exchange membranes. Background Technique

[0002] Anion exchange membranes are one of the key components of fuel cells, etc. They mainly play the role of conducting hydroxide ions to form an internal path, isolating hydrogen and oxygen generated at both poles to avoid dangerous accidents. To increase the surface area of the membrane and improve its performance, organic solvent volatilization is often used to make the membrane surface porous. The membrane can be formed by impregnation or casting methods. After initial film formation, the membrane needs to be dried to volatilize the excess organic solvent on the membrane surface, thereby forming a pore structure on the membrane surface.

[0003] For example, the patent document with the publication number CN216953822U discloses a drying device for ion exchange membranes. This device clamps the ion exchange membrane in a suspended manner inside the oven through a fixture, heats it using multiple heating plates on the side wall of the oven, and blows air on the ion exchange membrane using a blower installed at the top of the oven, thereby realizing the drying of the ion exchange membrane. However, since the installation position of the blower is fixed, the blowing range of the blower is certain. When processing ion exchange membranes with different sizes, for smaller ion exchange membranes, part of the air blown by the blower cannot reach the ion exchange membrane, resulting in waste of energy. For larger ion exchange membranes, the air blown by the blower is difficult to completely reach the ion exchange membrane, resulting in poor drying effect. Content of the Utility Model

[0004] The purpose of the utility model is to provide a drying oven for ion exchange membranes to solve the above problems.

[0005] The utility model realizes the above purpose through the following technical solutions:

[0006] A drying oven for ion exchange membranes includes an oven. A hot air mechanism is provided at the top of the oven. The hot air mechanism has multiple air outlets. A blowing mechanism is provided at the air outlets of the hot air mechanism. The blowing mechanism includes a fixed pipe fixed at the air outlet of the hot air mechanism. A movable pipe is slidably sleeved at the bottom end of the fixed pipe. A spring is fixedly connected to the top of the movable pipe, and the top end of the spring is fixedly connected to the hot air mechanism. Pressing blocks are fixedly connected to both sides of the movable pipe and are inclined. A closing mechanism is arranged inside the blowing mechanism. An extrusion mechanism for jacking up the movable pipe is arranged below the blowing mechanism. A clamping mechanism is arranged inside the oven. Both the extrusion mechanism and the clamping mechanism are provided with two groups and are symmetric left and right. A translation mechanism is arranged at the bottom end inside the oven, and the translation mechanism is used to drive the two groups of extrusion mechanisms and the two groups of clamping mechanisms to move relatively.

[0007] Preferably, the closing mechanism includes a first closing plate and a second closing plate which are arranged in parallel up and down. A plurality of first through holes are formed in the first closing plate, and a plurality of second through holes are formed in the second closing plate. The first through holes and the second through holes are arranged in a staggered manner. The first closing plate is fixedly connected to the bottom of the fixed pipe, and the second closing plate is fixedly connected to the inner wall of the movable pipe.

[0008] Preferably, the translation mechanism includes a translation motor which is fixedly connected to the bottom end inside the oven. The output shaft of the translation motor is fixedly connected with a bidirectional lead screw. The bidirectional lead screw is installed at the bottom end inside the oven through a bearing seat. Two symmetrically arranged sliding seats are threadedly connected to the bidirectional lead screw. A sliding groove is formed in the bottom end inside the oven, and the sliding seat is slidably connected to the sliding groove.

[0009] Preferably, the extrusion mechanism includes a vertical rod which is fixedly connected to the sliding seat. The top of the vertical rod is fixedly connected with an extrusion plate, and one end of the extrusion plate close to the center of the oven is provided with an inclined surface.

[0010] Preferably, steel balls are movably embedded in the inclined surface of the extrusion plate.

[0011] Preferably, the clamping mechanism includes a flipping motor which is fixedly connected to the top of the sliding seat. The output shaft of the flipping motor is fixedly connected with a flipping plate, and a clamp is installed on one side of the flipping plate close to the center of the oven.

[0012] Preferably, the hot air mechanism includes a hot air blower which is fixedly connected to the top of the oven. The air outlet end of the hot air blower is connected with an air guide pipe. An installation block is fixedly connected to the air guide pipe, and the installation block is fixedly connected to the inner top wall of the oven. The air outlet of the hot air mechanism is formed at the bottom of the air guide pipe. The fixed pipe is communicated with the air guide pipe through the air outlet, and the top end of the spring is fixedly connected to the installation block.

[0013] The beneficial effects are as follows: Adjust the distance between the clamping mechanism and the extrusion mechanism according to the length of the ion exchange membrane. On the one hand, it enables the clamping mechanism to adapt to the length of the ion exchange membrane. On the other hand, if the extrusion mechanisms approach each other, more movable pipes will be blocked, reducing the number of movable pipes that can discharge air and narrowing the blowing range to adapt to a shorter ion exchange membrane. If the extrusion mechanisms move away from each other, the number of movable pipes that can discharge air will increase and the blowing range will become wider to adapt to a longer ion exchange membrane. This not only avoids excessive waste of hot air energy but also ensures the drying effect.

[0025] The present utility model will be further described below with reference to the drawings:

[0026] As Figures 1-6 shown, a drying oven for an ion exchange membrane includes an oven 1. A hot air mechanism 2 is provided at the top of the oven 1. The hot air mechanism 2 has a plurality of air outlets. A blowing mechanism 3 is provided at the air outlets of the hot air mechanism 2. The hot air mechanism 2 includes a hot air blower 201. The hot air blower 201 is connected to the top of the oven 1 by screws. The air outlet end of the hot air blower 201 is connected to an air guide pipe 202. An installation block 203 is fixedly connected to the air guide pipe 202. The installation block 203 is fixedly connected to the inner top wall of the oven 1. The air outlets of the hot air mechanism 2 are opened at the bottom of the air guide pipe 202. The hot air blower 201 is used to introduce hot air into the air guide pipe 202, and the hot air is blown onto the ion exchange membrane 8 through the blowing mechanism 3 to realize the drying of the ion exchange membrane 8.

[0027] The blowing mechanism 3 includes a fixed pipe 301. The fixed pipe 301 is fixed at the air outlet of the hot air mechanism 2. The bottom end of the fixed pipe 301 is slidably sleeved with a movable pipe 302. A spring 303 is fixedly connected to the top of the movable pipe 302. The top end of the spring 303 is fixedly connected to the hot air mechanism 2. The fixed pipe 301 is communicated with the air guide pipe 202 through the air outlet. The top end of the spring 303 is fixedly connected to the installation block 203. Two inclined pressure-bearing blocks 304 are fixedly connected to both sides of the movable pipe 302. A closing mechanism 7 is arranged inside the blowing mechanism 3. An extrusion mechanism 4 for jacking up the movable pipe 302 is arranged below the blowing mechanism 3. A clamping mechanism 5 is arranged inside the oven 1. Both the extrusion mechanism 4 and the clamping mechanism 5 are provided with two groups and are symmetric left and right. A translation mechanism 6 is arranged at the inner bottom end of the oven 1. The translation mechanism 6 is used to drive the two groups of extrusion mechanisms 4 and the two groups of clamping mechanisms 5 to move relatively.

[0028] The translation mechanism 6 includes a translation motor 601, which is connected to the inner bottom end of the oven 1 by screws. The output shaft of the translation motor 601 is connected to a bidirectional lead screw 602 through a coupling. The bidirectional lead screw 602 is installed on the inner bottom end of the oven 1 through a bearing block. Two symmetrically arranged sliding seats 603 are threadedly connected to the bidirectional lead screw 602. A chute 101 is opened at the inner bottom end of the oven 1, and the sliding seat 603 is slidably connected to the chute 101. By driving the bidirectional lead screw 602 to rotate through the translation motor 601, the bidirectional lead screw 602 drives the two sliding seats 603 to approach or move away from each other. The clamping mechanism 5 and the extrusion mechanism 4 are both installed on the sliding seat 603, so that the clamping mechanism 5 and the extrusion mechanism 4 move simultaneously.

[0029] The extrusion mechanism 4 includes a vertical rod 401, which is connected to the sliding seat 603 by screws. The top of the vertical rod 401 is connected to an extrusion plate 402 by screws. One end of the extrusion plate 402 close to the center of the oven 1 is provided with an inclined surface 403. When the extrusion plate 402 moves towards the center of the oven 1, the inclined surface 403 of the extrusion plate 402 will squeeze the pressure-bearing block 304, causing the pressure-bearing block 304 to drive the movable tube 302 to move upward. As the extrusion plate 402 moves, the bottom of the movable tube 302 adheres to the top of the extrusion plate 402, thereby blocking the bottom of the movable tube 302 and preventing the movable tube 302 from blowing air. Steel balls 404 are movably embedded on the inclined surface 403 of the extrusion plate 402. The use of the steel balls 404 can reduce the friction generated between the inclined surface 403 and the pressure-bearing block 304, making it easier for the pressure-bearing block 304 to be squeezed upward.

[0030] The clamping mechanism 5 includes a flipping motor 501, which is connected to the top of the sliding seat 603 by screws. The output shaft of the flipping motor 501 is fixedly connected to a flipping plate 502. A clamp 503 is installed on one side of the flipping plate 502 close to the center of the oven 1. The ion exchange membrane 8 is clamped by the clamp 503, so that the ion exchange membrane 8 is suspended inside the oven 1.

[0031] The closing mechanism 7 includes a first closing plate 701 and a second closing plate 703 which are arranged parallel to each other up and down. A plurality of first through holes 702 are formed in the first closing plate 701, and a plurality of second through holes 704 are formed in the second closing plate 703. The first through holes 702 and the second through holes 704 are arranged in a staggered manner. The first closing plate 701 is fixedly connected to the bottom of the fixed pipe 301, and the second closing plate 703 is fixedly connected to the inner wall of the movable pipe 302. When the movable pipe 302 is upwardly extruded, the movable pipe 302 drives the second closing plate 703 to move upward, so that the second closing plate 703 is in close contact with the first closing plate 701. At this time, both the first through holes 702 and the second through holes 704 are blocked, so that the air in the fixed pipe 301 cannot enter the movable pipe 302, thus avoiding air leakage at the contact between the movable pipe 302 and the pressing plate 402 and ensuring the closing effect. Rubber layers are provided on the opposite surfaces of the first closing plate 701 and the second closing plate 703 to improve the sealing effect.

[0032] Working principle: During use, the ion exchange membrane 8 is fixed on the fixture 503. The hot air blower 201 supplies hot air into the air guide pipe 202. The hot air blows out after passing through the fixed pipe 301, the first through holes 702, the second through holes 704 and the movable pipe 302 in sequence, realizing the drying of the ion exchange membrane 8. The flipping motor 501 drives the flipping plate 502 to rotate, so that the ion exchange membrane 8 is flipped to ensure uniform drying.

[0033] For ion exchange membranes 8 of different lengths, the positions of the extrusion mechanism 4 and the clamping mechanism 5 need to be adjusted. If the length of the ion exchange membrane 8 is short, the translation motor 601 drives the bidirectional lead screw 602 to rotate. The bidirectional lead screw 602 drives the two sliding seats 603 to approach each other. The sliding seat 603 drives the flipping motor 501 to move, so that the fixtures 503 on both sides approach each other to adapt to the length of the ion exchange membrane 8. At the same time, the sliding seat 603 drives the pressing plate 402 to move through the vertical rod 401. The two pressing plates 402 approach each other, so that the inclined surface 403 of the pressing plate 402 presses the pressure bearing block 304. The pressure bearing block 304 drives the movable pipe 302 to move upward, so that the pressing plate 402 blocks the bottom of the movable pipe 302. At the same time, the movable pipe 302 drives the second closing plate 703 to move upward, so that the second closing plate 703 is in close contact with the first closing plate 701. In this way, the movable pipe 302 cannot blow air, reducing the number of movable pipes 302 that can blow air and narrowing the blowing range to adapt to the shorter ion exchange membrane 8. Similarly, when the ion exchange membrane 8 is long, the clamping mechanism 5 is separated from each other, and at the same time, the pressing plates 402 are separated from each other. The pressing plate 402 leaves the bottom of the movable pipe 302, and the spring 303 rebounds to make the movable pipe 302 move downward, so that the first closing plate 701 and the second closing plate 703 are separated. At this time, the movable pipe 302 can blow air, thus increasing the number of movable pipes 302 that can blow air and widening the blowing range to adapt to the longer ion exchange membrane 8.

Those skilled in the art should understand that the present utility model is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present utility model. Without departing from the spirit and scope of the present utility model, the present utility model will have various changes and improvements, and all these changes and improvements fall within the scope of the present utility model claimed.
