Description

Technical Field

[0001] The present invention relates to the technical field of electrode plate production, in particular to a uniform drying device and method for electrode plate production. Background Art

[0002] An electrolyzer consists of a cell, an anode, and a cathode, most often separated by a diaphragm. Depending on the electrolyte, they are classified into three categories: aqueous solution electrolyzers, molten salt electrolyzers, and non-aqueous solution electrolyzers. When direct current passes through the electrolyzer, an oxidation reaction occurs at the anode-solution interface, while a reduction reaction occurs at the cathode-solution interface, producing the desired product. The electrode plates in the electrolyzer are key to hydrogen production through electrolysis.

[0003] The base material of the electrode sheet is foam nickel, which has many excellent characteristics. In the process of processing the foam nickel into an electrode sheet, it needs to be placed in a PP box body, and then various catalysts are added to the box body. The catalysts are deposited on the surface of the foam nickel under the high temperature of the tunnel furnace, thereby achieving various conductive properties of the foam nickel. After the deposition is completed, a cleaning process is carried out, and then a drying step is carried out. In the prior art, the drying device for small-sized and large-volume electrode plates generally adopts an oven, which has a multi-layer structure from top to bottom. The electrode plate is placed in the oven for drying and then taken out to achieve drying of the electrode plate. In actual operation, in the process of placing the electrode plate in or taking it out of the oven, the internal environment of the oven is in a connected state with the external environment, and the air pressure inside the oven is greater than the atmospheric environment pressure. The air pressures in the two environments will form convection, which seriously affects the internal environment of the oven, mainly causing turbulence in the air flow inside the oven and lowering the temperature inside the oven, causing other electrode plates dried in the oven to be heated unevenly, affecting the quality of the electrode plates. In view of this, the inventors proposed a uniform drying device and method for electrode plate production. Summary of the Invention

[0015] The connecting pipe is provided with a valve, which includes a valve body and an adjusting switch. The fixed wheel is provided with a sleeve, and the adjusting switch is coaxially connected to the sleeve. When the gear rotates and drives the rotating shaft to rotate, the sleeve drives the valve to close or open.

[0016] A plurality of positioning blocks for fixing the electrode plates are evenly arranged on the placement plate, and the positioning blocks are arranged parallel to the direction of movement of the placement plate. A wind gathering plate is provided on the placement plate, and the heights of the plurality of wind gathering plates gradually increase along the direction from the baffle to the fixed plate; wherein the wind gathering plate is a bent plate connected end to end, and the bending position of the bent plate is between two adjacent positioning blocks.

[0043] like Figures 1-10 As shown, the present invention provides a uniform drying device and method for producing electrode plates.

[0044] like Figure 1-Figure 3 As shown, in an exemplary embodiment, a uniform drying device for producing electrode plates includes:

[0045] The housing 1 is provided with a plurality of feed troughs 104;

[0046] Multiple drying mechanisms 4, the drying mechanisms 4 are horizontally movably arranged in the housing 1, and the drying mechanisms 4 include a placement plate 403 and a sealing plate 405, the sealing plate 405 is rotatably connected to the placement plate 403, and an elastic member 409 is provided between the sealing plate 405 and the placement plate 403;

[0047] The heating mechanism 2 is arranged in the housing 1 and is provided with a heating component 3 for providing heat to each drying mechanism 4;

[0048] The plate pulling mechanism includes a rotating shaft 501 rotatably connected to the housing 1 and a fixed wheel 503 fixedly connected to the rotating shaft 501. The fixed wheel 503 is provided with a connecting piece 505 connected to the sealing plate 405. A transmission mechanism 5 for rotating the fixed wheel 503 is provided between the plate pulling mechanism and the sealing plate 405.

[0049] Controller 602 , controller 602 controls the connection with heating mechanism 2 and drying mechanism 4 .

[0050] In this embodiment, a movable drying mechanism 4 is provided so that the drying mechanism 4 can enter or pass through the shell 1, which is convenient for placing the electrode plate on the placement plate 403 or taking out the electrode plate. At the same time, the sealing plate 405 is rotatably connected to the placement plate 403. Through the provided sealing plate 405 and the connecting piece 505, when the drying mechanism 4 passes through the shell 1, the sealing plate 405 rotates to isolate the external environment from the internal environment of the shell 1, preventing the internal environment of the shell 1 from communicating with the external environment, ensuring the stability of the internal environment of the shell 1, and providing a good environment for uniform heating of the electrode plate. In this embodiment, when the sealing plate 405 is rotated to the maximum angle, it is perpendicular to the placement plate 403. At the same time, when the sealing plate 405 is vertical, its height is greater than the height of the feed trough 104, so that when the drying mechanism 4 is extended, the feed trough 104 is stuck through the sealing plate 405 to prevent external air from entering the interior of the shell 1.

[0051] Furthermore, by means of the pulling plate mechanism, when the drying mechanism 4 moves, the fixed wheel 503 can be driven to rotate through the transmission mechanism 5, thereby retracting and extending the connecting piece 505, and realizing the rotation of the sealing plate 405, thereby indirectly utilizing the movement of the drying mechanism 4 to drive the rotation of the sealing plate 405, thereby increasing the functionality of the drying mechanism 4.

[0052] In the present invention, the heating mechanism 2 and the heat supply assembly 3 are provided to provide heat for each drying mechanism 4, thereby ensuring that an independent heating space is formed between each drying mechanism 4 and reducing the mutual influence between the drying mechanisms 4.

[0053] It is worth noting that, in this embodiment, the drying mechanisms 4 are arranged on the housing 1 from top to bottom, and there are eight of them.

[0054] like Figure 1-Figure 3 As shown, in an exemplary embodiment, the shell 1 includes a frame 101 and an inner shell 102, an isolation block 106 is arranged on the inner shell 102, a plurality of exchange tubes 103 are arranged between the frame 101 and the inner shell 102, and evaporation holes are provided on the exchange tubes 103 for conducting water vapor generated in the drying mechanism 4, and the cylinder 401 is arranged on the frame 101.

[0055] In this embodiment, the shell 1 is divided into two layers, namely an inner shell 102 and a frame 101 arranged on the outer layer of the inner shell 102. There are two inner shells 102, which are arranged on the left and right sides of the frame 101. The inner shell 102 and the outer shell are connected by multiple exchange tubes 103. At the same time, evaporation holes are provided on the exchange tubes 103. The inner end of the exchange tube 103 is connected to the internal space of the drying mechanism 4, and the outer end is connected to the atmospheric environment, so that the evaporation holes can lead out the water vapor generated in the drying mechanism 4 to facilitate drying of the electrode plates.

[0056] Illustratively, in this embodiment, the number of exchange tubes 103 is forty-eight, the number of exchange tubes 103 on a single side is twenty-four, the number of exchange tubes 103 corresponding to each layer of drying mechanism 4 is six, and the number of exchange tubes 103 on a single side is three; illustratively, a plurality of support seats 107 are further provided between the inner shells 102, and the number of support seats 107 corresponding to each drying mechanism 4 is two, which provide support and guidance for the movement of the drying mechanism 4.

[0057] It is worth noting that in this embodiment, the frame 101 is further provided with a column 105, which can support the entire device. Specifically, the frame 101 is connected to the column 105 by screws. The frame 101 is also provided with a back cover to facilitate the repair and maintenance of the components inside the shell 1.

[0058] It should also be noted that, in this embodiment, the isolation blocks 106 are provided to separate the drying mechanisms 4 from each other.

[0059] like Figure 3 、 Figure 8 and Figure 9 As shown, in an exemplary embodiment, the drying mechanism 4 also includes baffles 404 arranged on both sides of the placement plate 403, the width between the baffles 404 is greater than the width of the feed trough 104, and a plurality of isolation blocks 106 are also provided in the shell 1, and the placement plate 403 is slidably connected to the isolation blocks 106.

[0060] In this embodiment, an isolation block 106 is fixed to the inner wall of the inner shell 102, wherein the placement plate 403 is slidably connected to the isolation block 106 to ensure stable movement of the placement plate 403. At the same time, the width of the isolation blocks 106 on both sides plus the width of the placement plate 403 between the isolation blocks 106 is equal to the width between the inner shells 102, so as to realize the partition of the drying mechanism 4 and reduce the mutual influence between the drying mechanisms 4.

[0061] Exemplarily, in this embodiment, the baffle 404 is installed on the surface of the placement plate 403 by screws, and is located on both sides of the sealing plate 405. Its height is also greater than the height of the feed trough 104. Exemplarily, in this embodiment, the width of the baffles 404 on both sides plus the width of the sealing plate 405 is greater than the width of the feed trough 104 to prevent the internal environment of the shell 1 from communicating with the external environment.

[0062] like Figure 8 and Figure 9 As shown, it is worth noting that in this embodiment, a mounting groove 408 is provided on the surface of the placement plate 403, and a plurality of elastic members 409 are provided in the mounting groove 408. One end of the elastic member 409 is hinged in the mounting groove 408, and the other end of the elastic member 409 is hinged to the sealing plate 405. When the sealing plate 405 is not subjected to force, the angle between the sealing plate 405 and the placement plate 403 is 5°.

[0063] It should also be noted that two guide rods are symmetrically fixedly connected to the baffle 404, and the guide rods are slidably connected to the support seat 107 to guide the movement of the placement plate 403. At the same time, a connecting frame 410 is also fixedly connected to the placement plate 403 to enhance the strength of the placement plate 403.

[0064] like Figure 1-Figure 3 、 Figure 8 and Figure 9 As shown, in an exemplary embodiment, the drying mechanism 4 also includes a fixed plate 402 and a cylinder 401. The cylinder 401 is installed on the frame 101. The fixed plate 402 is fixedly connected to the end of the placement plate 403. The fixed plate 402 is located outside the shell 1. The shell 1 is provided with a cylinder 401. The protruding end of the cylinder 401 is connected to the fixed plate 402. The cylinder 401 drives the fixed plate 402 to move horizontally to drive the placement plate 403 to move horizontally.

[0065] In this embodiment, the cylinder 401 can drive the fixed plate 402 to move, so that the fixed plate 402 can drive the placement plate 403 to be pushed out, thereby removing the drying mechanism 4 from the shell 1 to facilitate taking out or placing the electrode plate.

[0066] Exemplarily, in this embodiment, the number of corresponding cylinders 401 in each drying mechanism 4 is two, which are arranged on the side walls of the frame 101 on both sides. Exemplarily, in this embodiment, the length and width of the fixing plate 402 are both greater than the length and width of the feed trough 104. When the placement plate 403 is located inside the shell 1, the fixing plate 402 is against the outer wall of the frame 101 to ensure the sealing performance of the internal environment.

[0067] It is worth noting that in this embodiment, when the extended end of the cylinder 401 is extended to the maximum displacement, the sealing plate 405 and the baffle 404 are against the inner wall of the feed trough 104. It should also be noted that in this embodiment, the cylinder 401 is controlled by the controller 602, and the two cylinders 401 corresponding to the same drying mechanism 4 move synchronously, and the movement rate and movement time are exactly the same, which has ensured the stability of the movement of the drying mechanism 4.

[0068] like Figure 10 As shown, in an exemplary embodiment, the transmission mechanism 5 includes a gear 502 and a rack 411 . The rack 411 is fixedly connected to the placement plate 403 . The gear 502 is disposed on the rotating shaft 501 , and the gear 502 is meshed with the rack 411 .

[0069] In this embodiment, by arranging a rack 411 on the placement plate 403 , the gear 502 meshing with the rack can be driven to rotate during the movement of the drying mechanism 4 , thereby driving the fixed wheel 503 to rotate, thereby realizing the retraction and extension of the connecting member 505 .

[0070] Illustratively, in this embodiment, the rotating shaft 501 is rotatably connected to the side wall of the inner shell 102 , and the fixed wheel 503 is fixedly connected to the rotating shaft 501 .

[0071] It is worth noting that, in this embodiment, the number of the racks 411 is two, and the number of the corresponding rotating shafts 501 and gears 502 is also two. The gears 502 on both sides rotate synchronously, and the fixed wheels 503 on both sides rotate synchronously.

[0072] It should also be noted that in this embodiment, the connecting member 505 adopts an Oxford double-layer flat elastic band, which is resistant to high temperature and has good elasticity. One end of the connecting member is sleeved on the end face of the sealing plate 405, and the other end is wrapped around the fixed wheel 503. When the drying mechanism 4 is located inside the shell 1, the connecting member 505 is wrapped around the fixed wheel 503. When the drying mechanism 4 is extended, the fixed wheel 503 rotates, and the connecting member 505 is gradually released. When the rack 411 leaves the gear 502 and no longer engages, the connecting member 505 is completely released at this time, and the drying mechanism 4 continues to move outward. Since the connecting member 505 is elastic, it is stretched and the sealing plate 405 is pulled up at the same time until the sealing plate 405 is perpendicular to the placement plate 403.

[0073] like Figure 7As shown, in an exemplary embodiment, the heating component 3 includes a main air duct 301 and multiple air outlet pipes 305. The main air duct 301 is connected to the heating mechanism 2. Multiple connecting pipes 303 are provided on the main air duct 301, and the air outlet pipes 305 are arranged on the connecting pipes 303.

[0074] In this embodiment, the heating component 3 is divided into three parts, namely a main air duct 301 connected to the heating mechanism 2, a connecting pipe 303 connected to the main air duct 301, and an air outlet duct 305 arranged on the connecting pipe 303. The main air duct 301 is mainly used to conduct the hot air transmitted from the heating mechanism 2, and the connecting pipe 303 is used to connect the hot air to each air outlet duct 305, and then the air outlet duct 305 blows the hot air to each drying mechanism 4.

[0075] Exemplarily, the number of the connecting pipes 303 is eight, which are evenly arranged from top to bottom. The number of the air outlet pipes 305 on each connecting pipe 303 is five, which are evenly arranged on the connecting pipe 303 and aligned with the internal space of the drying mechanism 4.

[0076] It is worth noting that in this embodiment, a main control valve 302 is provided on the main air duct 301. If the main control valve 302 is closed, drying cannot continue. When the main control valve 302 is opened, drying can be carried out. In this embodiment, the main control valve 302 is controlled by the controller 602.

[0077] like Figure 7-Figure 9 As shown, in an exemplary embodiment, a valve 304 is provided on the connecting pipe 303, and the valve 304 includes a valve 304 body and an adjusting switch. A sleeve is provided on the fixed wheel 503, and the adjusting switch is coaxially connected to the sleeve, wherein when the gear 502 rotates to drive the rotating shaft 501 to rotate, the sleeve drives the valve 304 to close or open.

[0078] In this embodiment, an adjusting switch is provided on the connecting pipe 303, and a sleeve is provided on the fixed wheel 503, so that when the fixed wheel 503 rotates, it can drive the valve 304 to rotate, thereby opening or closing the valve 304. When the drying mechanism 4 is extended, the valve 304 on the corresponding connecting pipe 303 is closed, which saves energy and is beneficial to the stability of the internal environment of the shell 1.

[0079] For example, in this embodiment, there are two valves 304 on the connecting pipe 303 , one in front and one in the back, which need to be opened at the same time to connect the air outlet pipe 305 and the main air pipe 301 .

[0080] For example, in this embodiment, since the valves 304 are arranged on the connecting pipe 303 one after the other, the distances between the fixing wheel 503 and the sealing plate 405 are different, and the lengths of the selected connecting members 505 are also different.

[0081] It is worth noting that in this embodiment, the sleeve is fixedly connected to the side wall of the fixed wheel 503, and the end portion is sleeved with the switch of the valve 304, which can drive the switch of the valve 304 to rotate synchronously. When the rack 411 just leaves the gear 502 and no longer engages with the gear 502, the valve 304 is completely closed.

[0082] like Figure 8 and Figure 9 As shown, in an exemplary embodiment, a plurality of positioning blocks 406 for fixing the electrode plates are evenly arranged on the placement plate 403, and the positioning blocks 406 are arranged parallel to the direction in which the placement plate 403 moves. An air collecting plate 407 is provided on the placement plate 403, and the heights of the plurality of air collecting plates 407 gradually increase along the direction from the baffle 404 to the fixing plate 402;

[0083] The wind gathering plate 407 is a bent plate connected end to end, and the bending position of the bent plate is between two adjacent positioning blocks 406 .

[0084] In this embodiment, the wind collecting plate 407 is provided to diffuse the hot air blown out from the air outlet pipe 305 to both sides, so that the hot air contacts the electrode plate more quickly, thereby improving the drying efficiency of the electrode plate.

[0085] Illustratively, in this embodiment, the number of positioning blocks 406 in each drying mechanism 4 is sixteen, distributed in an array, and the number of wind gathering plates 407 is four, which are arranged on the left side of the positioning blocks 406 in each column; illustratively, in this embodiment, the bending part of the wind gathering plate 407 is located between the horizontally arranged positioning blocks 406 to facilitate heat diffusion.

[0086] It is worth noting that the height of the wind collecting plate 407 increases from right to left. The area of ​​direct contact between the electrode plate on the right and the hot air is larger. The speed of the hot air is highest when it comes out of the air outlet pipe 305. When the hot air blows to the electrode plate on the left, the speed decreases. At this time, the height of the wind collecting plate 407 increases successively, so that the wind collecting plate 407 near the left side can diffuse more hot air, thereby increasing the contact area between the hot air and the electrode plate near the left side.

[0087] like Figure 2 、 Figure 4 and Figure 5 As shown, in an exemplary embodiment, the heating mechanism 2 includes a heating box 201 fixed to the bottom of the inner shell 102, a plurality of heating tubes 202 arranged in the heating box 201 and evenly arranged, and a fan 203 arranged in the heating box 201, and a main air duct 301 is arranged on the heating box 201 and is connected to the internal space of the heating box 201.

[0088] In this embodiment, the heating tube 202 generates heat, and then the hot air is sent into the main air duct 301 through the fan 203 to provide heat.

[0089] In this embodiment, the heating mechanism 2 is connected to the controller 602, and the power of the heating tube 202 is controlled by the controller 602, thereby controlling the temperature required for drying.

[0090] like Figure 1 and Figure 4 As shown, in an exemplary embodiment, a control component 6 is further provided on the housing 1 , and the control component 6 includes a protective shell 601 arranged on the top surface of the rack 101 and a temperature sensor 603 arranged inside the housing 1 , wherein the controller 602 is arranged inside the protective shell 601 .

[0091] In this embodiment, the master control valve 302 , the cylinder 401 and the temperature sensor 603 are all electrically connected to the controller 602 .

[0092] The present invention also provides a uniform drying method for electrode plate production, which uses the above-mentioned uniform drying device for electrode plate production and includes the following steps:

[0093] The controller 602 controls the cylinder 401 to push out the placement plate 403, and the cleaned electrode plate is placed in the positioning block 406 for positioning and fixing. The controller 602 then resets the placement plate 403. At this time, the electrode plate is located inside the housing 1.

[0094] The controller 602 opens the main control valve 302 and the heating mechanism 2 at the same time. The heating mechanism 2 supplies hot air to the drying mechanism 4 to dry the electrode plates. When the hot air enters, it hits the air collecting plate 407, which then spreads the hot air to both sides, thereby accelerating the drying efficiency.

[0095] When the electrode plate needs to be taken out, the controller 602 controls the corresponding cylinder 401 to push out the required placement plate 403. At this time, the rack 411 drives the gear 502 to rotate, the fixed wheel 503 rotates, the connecting piece 505 is released, the placement plate 403 continues to move, the connecting piece 505 stretches and pulls up the sealing plate 405 until it is vertical. The sealing plate 405 no longer rotates, and the cylinder 401 continues to extend until the sealing plate 405 and the baffle 404 jam the feed chute 104, preventing the internal space of the shell 1 from communicating with the external space, thereby ensuring the stability of the internal environment;

[0096] When the rack 411 drives the gear 502 to rotate, the gear 502 drives the rotating shaft 501 to rotate, and the rotating shaft 501 drives the fixed wheel 503 to rotate, the sleeve 504 rotates synchronously, driving the corresponding valve 304 to switch and rotate, so as to close the corresponding valve 304 to prevent the continuous output of hot air, and the operator takes out the dried electrode plate;

[0097] After the new electrode plate is placed, the cylinder 401 is controlled by the controller 602 to drive the placement plate 403 to reset. During the reset process, the connecting piece 505 elastically contracts until it is no longer stretched. At this time, the rack 411 is engaged with the gear 502 again, driving the fixed wheel 503 to rotate in the opposite direction, so that the connecting piece 505 is wrapped around the fixed wheel 503, and the connecting piece 505 is retracted. The sealing plate 405 is not subjected to the tension of the connecting piece 505, and is reset by the elastic force of the elastic piece 409, and rotates counterclockwise. The valve 304 is opened again due to the reverse rotation of the fixed wheel 503, and the sleeve is driven to rotate in the opposite direction. The air outlet pipe 305 can supply air to the drying mechanism 4 again to dry the electrode plate.

[0098] To sum up, the present invention isolates the internal environment of the shell 1 from the external environment by setting up the drying mechanism 4, transmission mechanism 5 and heating component 3, prevents the external environment from affecting the internal environment of the shell 1 when placing or collecting the electrode plates, and ensures uniform drying of the electrode plates in the shell 1.

Anyone skilled in the art may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by one of ordinary skill in the art without departing from the spirit and technical principles disclosed herein are intended to be covered by the claims of the present invention.
