The drying box is provided with a lower opening and an upper opening arranged opposite to each other in the direction of gravity, the upper opening being located above the lower opening.

The first air nozzle group and the second air nozzle group are both located in the drying box, and are respectively located on either side of a line connecting the lower opening and the upper opening.
[0008] As an optional solution of the above-mentioned carbon paper drying device, the first air nozzle group includes a plurality of first air nozzles spaced apart along the gravity direction; and / or
[0009] The second nozzle group includes a plurality of second nozzles spaced apart along the direction of gravity.
[0010] Carbon paper hydrophobic treatment equipment, including:
[0011] The carbon paper drying device mentioned above;
[0012] A hydrophobic box device includes a liquid-piercing roller group and a hydrophobic box. The hydrophobic box is used to place hydrophobic liquid. The hydrophobic box is provided with a carbon paper output port, and the liquid-piercing roller group is provided at the carbon paper output port.
[0013] As an optional solution of the above-mentioned carbon paper hydrophobic treatment equipment, the piercing roller group is arranged relative to the lower opening and spaced apart, and the carbon paper output from the hydrophobic box device can enter the drying box through the piercing roller group.
[0014] As an optional solution of the above-mentioned carbon paper hydrophobic treatment equipment, the hydrophobic tank device further includes:
[0015] A guide roller is provided on the outside of the hydrophobic box and is used to guide the carbon paper into the hydrophobic box;
[0016] The pressing roller assembly is at least partially located in the hydrophobic box, and the carbon paper entering the hydrophobic box can be transported to the liquid-piercing roller group via the pressing roller assembly.
[0017] As an optional solution of the above carbon paper hydrophobic treatment device, the lower opening and the carbon paper outlet are opposite to each other along the direction of gravity and are spaced apart.
[0018] As an optional solution of the above-mentioned carbon paper hydrophobic treatment equipment, the carbon paper hydrophobic treatment equipment also includes a carbon paper sintering device, the carbon paper sintering device includes a sintering box, and a plurality of first guide rollers are arranged in the sintering box. The plurality of first guide rollers are arranged at intervals along the conveying direction of the carbon paper.
[0019] As an optional solution of the above-mentioned carbon paper hydrophobic treatment equipment, an upper air chamber and a lower air chamber are further provided in the sintering box, the upper air chamber is located on the upper side of the first guide roller, and the lower air chamber is located on the lower side of the first guide roller.
[0020] As an optional solution of the above-mentioned carbon paper hydrophobic treatment equipment, the carbon paper hydrophobic treatment equipment also includes a cooling device, the cooling device includes a cooling box, the cooling box is connected to the outlet of the sintering box, and a plurality of second guide rollers are arranged in the cooling box, and the plurality of second guide rollers are arranged at intervals along the conveying direction of the carbon paper.
[0021] As an optional solution for the above-mentioned carbon paper hydrophobic treatment equipment, a third air nozzle group and a fourth air nozzle group are arranged in an upper and lower interval in the cooling box. The third air nozzle group is located on the upper side of the second guide roller, and the fourth air nozzle group is located on the lower side of the second guide roller.
[0022] Beneficial effects of the utility model:
[0023] During operation, the carbon paper hydrophobic treatment device first transports carbon paper into a hydrophobic chamber device, allowing the carbon paper to be fully soaked with and absorb the hydrophobic liquid. After exiting the hydrophobic chamber device, the fully absorbed carbon paper enters a drying chamber through the upper opening. Because the upper and lower openings are positioned vertically relative to each other along the direction of gravity, the carbon paper entering the drying chamber is transported along the direction of gravity. A first nozzle group located on one side of the first surface of the carbon paper blows air toward the first surface, while a second nozzle group located on the second surface of the carbon paper blows air toward the second surface, thereby drying the carbon paper.
[0024] The carbon paper drying device proposed by the present invention is capable of conveying the carbon paper into the drying box in the direction of gravity. That is, the two opposing surfaces of the carbon paper with the hydrophobic liquid attached thereto are arranged horizontally relative to each other. Even if the hydrophobic liquid attached to the carbon paper is affected by gravity, it will not flow from one surface of the carbon paper to the other surface. Instead, it will flow downward under the action of gravity, thereby ensuring that the hydrophobicity of the two opposing surfaces of the carbon paper with the hydrophobic liquid attached thereto is consistent. Therefore, the hydrophobicity of the first surface and the second surface of the carbon paper will not be inconsistent. The device can also prevent the hydrophobic liquid from dripping from the carbon paper into the drying box, thus avoiding the need to clean the drying box. The carbon paper entering the drying box is conveyed in the direction of gravity. The first nozzle group located on the first surface of the carbon paper can blow air toward the first surface of the carbon paper, and the second nozzle group located on the second surface of the carbon paper can blow air toward the second surface of the carbon paper, thereby completing the drying of the carbon paper.
[0025] During operation, the carbon paper hydrophobic treatment device proposed in the present invention first conveys carbon paper into a hydrophobic chamber assembly, allowing the carbon paper to be fully soaked with and absorbed by a hydrophobic liquid. After exiting the hydrophobic chamber assembly, the fully absorbed carbon paper enters a drying chamber of a drying chamber assembly through a lower opening. The drying chamber assembly then dries the carbon paper, preventing the hydrophobicity between the first and second surfaces of the carbon paper from being inconsistent. Furthermore, the device prevents undried hydrophobic liquid from dripping from the carbon paper into the drying chamber, obviating the need for cleaning the drying chamber.

[0039] The present invention will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the present invention and are not intended to limit the present invention. It should also be noted that, for ease of description, the accompanying drawings only illustrate portions relevant to the present invention, not all of its components.
[0040] In the description of this utility model, unless otherwise specified or limited, the terms "connected," "connect," and "fixed" should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.
[0041] In the present invention, unless otherwise expressly specified or limited, a first feature being "above" or "below" a second feature may include the first and second features being in direct contact, or may include the first and second features being in contact not directly but through another feature between them. Moreover, a first feature being "above," "above," and "above" a second feature may include the first feature being directly above or obliquely above the second feature, or may simply mean that the first feature is higher in level than the second feature. A first feature being "below," "below," and "below" a second feature may include the first feature being directly below or obliquely below the second feature, or may simply mean that the first feature is lower in level than the second feature.
[0042] In the description of this embodiment, terms such as "upper," "lower," "left," and "right" are used to refer to positions or locations based on the positions or locations shown in the accompanying drawings. These terms are intended solely to facilitate description and simplify operation, and are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation. Therefore, they should not be construed as limitations on this invention. Furthermore, the terms "first" and "second" are used solely for descriptive purposes and have no special meaning.
[0043] It should be noted that the inventors' research has found that in related art, after the hydrophobic treatment is completed, the carbon paper is transported to a horizontal suspension drying box for drying. At this time, the carbon paper is always in a horizontal position. This causes the undried hydrophobic solution to flow from the upper surface of the carbon paper to the lower surface of the carbon paper under the action of gravity, resulting in the hydrophobic liquid being light on the top and heavy on the bottom, which in turn leads to inconsistent hydrophobicity between the upper and lower surfaces of the carbon paper, ultimately affecting the performance of the hydrogen fuel cell. Furthermore, most of the hydrophobic liquid is concentrated on the lower surface of the carbon paper, and the hydrophobic liquid easily drips from the carbon paper into the drying box, forming contaminants in the drying box that are difficult to clean. Over time, the contaminants will fall off with the circulating hot air and be blown by the hot air until they stick to the surface of the carbon paper entering the horizontal suspension drying box, contaminating the carbon paper and ultimately affecting the performance of the hydrogen fuel cell.
[0044] Based on this, see Figure 1 This embodiment provides a carbon paper hydrophobic treatment device, which can complete the hydrophobic treatment of the carbon paper 10 and ensure the consistency of the hydrophobicity of the surfaces of both sides of the carbon paper.
[0045] Specifically, see Figure 1 and Figure 2 In this embodiment, the carbon paper hydrophobic treatment equipment includes a hydrophobic box device 1 and a carbon paper drying device.
[0046] The hydrophobic liquid can be placed in the hydrophobic box device 1. The carbon paper 10 is immersed in the hydrophobic liquid, and the carbon paper 10 can fully absorb the hydrophobic liquid.
[0047] The carbon paper drying device includes a drying box assembly 2 .
[0048] The drying box assembly 2 includes a drying box 21, a first air nozzle group and a second air nozzle group. The drying box 21 is provided with a lower opening 212 and an upper opening 213 arranged opposite to each other in the direction of gravity. The upper opening 213 is located on the upper side of the lower opening 212. The carbon paper 10 attached with the hydrophobic liquid can enter the drying box 21 along the lower opening 212 and then pass through the drying box 21 through the upper opening 213 to be transported in the direction of gravity; the first air nozzle group and the second air nozzle group are both located in the drying box 21, and are respectively located on both sides of the line connecting the lower opening 212 and the upper opening 213.
[0049] The carbon paper 10 passes through the hydrophobic box device 1 and enters the drying box 21 from the lower opening 212 .
[0050] During operation, the carbon paper hydrophobic treatment device provided in this embodiment first conveys carbon paper 10 into the hydrophobic chamber device 1 so that the carbon paper 10 is fully soaked with and absorbs the hydrophobic liquid. After being fully absorbed by the hydrophobic liquid, the carbon paper 10 is conveyed from the hydrophobic chamber device 1 and enters the drying chamber 21 through the lower opening 212. Because the upper opening 213 and the lower opening 212 are positioned relative to each other in the direction of gravity, the carbon paper 10 entering the drying chamber 21 is conveyed in the direction of gravity. A first nozzle group located on one side of the first surface of the carbon paper 10 blows air toward the first surface of the carbon paper 10, and a second nozzle group located on the second surface of the carbon paper 10 blows air toward the second surface of the carbon paper 10, thereby completing the drying of the carbon paper 10.
[0051] Since the carbon paper 10 entering the drying box 21 can be transported in the direction of gravity, that is, the two opposing surfaces of the carbon paper 10 with the hydrophobic liquid attached are arranged horizontally opposite each other, the undried hydrophobic liquid attached to the carbon paper 10 will not flow from one surface to the other surface of the carbon paper 10 even under the action of gravity, but will flow downward under the action of gravity. This ensures that the hydrophobicity of the two opposing surfaces of the carbon paper 10 with the hydrophobic liquid attached is consistent, thereby preventing the hydrophobicity of the first and second surfaces of the carbon paper 10 from being inconsistent. This also prevents the undried hydrophobic liquid from dripping from the carbon paper 10 into the drying box 21, avoiding the need to clean the drying box 21.
[0052] It is understandable that, since the carbon paper 10 is transported in the direction of gravity, the flow of the hydrophobic liquid that has not been dried at this time also flows along the carbon paper 10 and does not drip.
[0053] Furthermore, in this embodiment, the hydrophobic tank device 1 includes a liquid-piercing roller assembly 13 and a hydrophobic tank 11. The hydrophobic tank 11 is used to store hydrophobic liquid. The hydrophobic tank 11 is provided with a carbon paper outlet 111, and the liquid-piercing roller assembly 13 is provided at the carbon paper outlet 111.
[0054] Optionally, the liquid-piercing roller group 13 can be arranged inside the drain box 11 or outside the drain box 11, as required.
[0055] Specifically, see Figure 2 and Figure 3 In this embodiment, the piercing roller assembly 13 is disposed at the carbon paper outlet 111 and outside the hydrophobic box 11 .
[0056] Furthermore, the piercing roller assembly 13 is spaced apart from the lower opening 212 , and the carbon paper 10 output from the hydrophobic box device 1 can enter the drying box 21 through the piercing roller assembly 13 .
[0057] The impingement roller assembly 13 removes excess hydrophobic liquid from the surface of the carbon paper 10 entering the drying box 21, improving the drying efficiency of the carbon paper 10 within the drying box 21 and effectively preventing the hydrophobic liquid from dripping onto the carbon paper 10 within the drying box 21. Furthermore, the impingement roller assembly 13 is spaced relative to the lower opening 212, allowing the carbon paper 10 passing through the impingement roller assembly 13 to directly enter the drying box 21 through the lower opening in the direction of gravity, thus avoiding the problem of uneven distribution of hydrophobic liquid on both surfaces of the carbon paper 10 before entering the drying box 21.
[0058] Specifically, the liquid-piercing roller group 13 includes two oppositely arranged liquid-piercing rollers 131. The two liquid-piercing rollers 131 are arranged in close contact, and the carbon paper 10 can pass between the two liquid-piercing rollers 131 so that the two liquid-piercing rollers 131 can remove excess hydrophobic liquid on the surface of the carbon paper 10 entering the drying box 21.
[0059] Alternatively, see Figure 2 , the first nozzle group includes a plurality of first nozzles 22 spaced apart along the direction of gravity; and / or
[0060] The second nozzle group includes a plurality of second nozzles 23 spaced apart along the gravity direction.
[0061] Optionally, in some embodiments, the first nozzle group includes a plurality of first nozzles 22 spaced apart along the direction of gravity. Optionally, in other embodiments, the second nozzle group includes a plurality of second nozzles 23 spaced apart along the direction of gravity.
[0062] Specifically, in this embodiment, the first nozzle group includes a plurality of first nozzles 22 spaced apart along the gravity direction, while the second nozzle group includes a plurality of second nozzles 23 spaced apart along the gravity direction. This arrangement can ensure the drying effect of the carbon paper 10.
[0063] For example, Figure 2Taking the shown orientation as an example, the first nozzle group is located on the left side of the carbon paper 10, and the second nozzle group is located on the right side of the carbon paper 10; the multiple first nozzles 22 blow air together toward the left surface (i.e., the first surface) of the carbon paper 10, and the multiple second nozzles 23 blow air together toward the right surface (i.e., the second surface) of the carbon paper 10, thereby completing the drying process of the carbon paper 10.
[0064] Specifically, the drying chamber of the drying box 21 includes a return air region 211. A first heating pack is installed within the drying chamber. A through-hole connecting to the first heating pack is provided on the sidewall of the return air region 211. After drying the carbon paper 10, the air flows into the return air region 211 through the through-hole and enters the first heating pack. The first heating pack heats the air entering through the through-hole. A blower is provided on one side of the first heating pack to blow the heated air from the first heating pack into the drying chamber. This cycle saves energy and prevents the hot air that has dried the carbon paper 10 from escaping directly from the drying box 21, which would otherwise be wasted.
[0065] Preferably, the return air area 211 is located at the top of the drying chamber of the drying box 21 .
[0066] Specifically, see Figure 2 and Figure 3 The drain box device 1 also includes a guide roller 12 and a pressure roller assembly.
[0067] The guide roller 12 is disposed on the outer surface of the hydrophobic box 11 and is used to guide the carbon paper 10 into the hydrophobic box 11 .
[0068] The pressing roller assembly is at least partially located in the hydrophobic box 11 , and the carbon paper 10 entering the hydrophobic box 11 can be transported to the piercing roller assembly 13 via the pressing roller assembly.
[0069] Specifically, the pressure roller assembly includes two pressure rollers 14 that are relatively spaced apart along the conveying direction of the carbon paper 10 in the hydrophobic box 11. The carbon paper 10 passes around the guide roller 12 from the upper surface of the guide roller 12, and is then conveyed along the lower surfaces of the two pressure rollers 14. It is conveyed from the carbon paper output port 111 of the hydrophobic box 11 to between the two liquid-binding rollers 131 of the liquid-binding roller group 13, and then passes through the drying box 21 along the direction of gravity.
[0070] Optionally, the conveying direction of the carbon paper 10 in the hydrophobic box 11 is horizontal.
[0071] It is understandable that both pressing rollers 14 are immersed in the hydrophobic liquid to ensure that the carbon paper 10 can be fully soaked in the hydrophobic liquid.
[0072] Optionally, the lower opening 212 of the drying box 21 and the carbon paper outlet 111 of the hydrophobic box 11 are arranged opposite each other in the direction of gravity and spaced apart. This arrangement allows the carbon paper 10 to be discharged from the carbon paper outlet 111 in the direction of gravity, ensuring that the carbon paper 10 can enter the drying box 21 in the direction of gravity, effectively avoiding the problem of uneven distribution of hydrophobic liquid on both surfaces of the carbon paper 10 before entering the drying box 21.
[0073] Specifically, after the carbon paper 10 is dried in the drying oven 21, the dried carbon paper 10 needs to be sintered. Figure 1 and Figure 4 In this embodiment, the carbon paper hydrophobic treatment equipment also includes a carbon paper sintering device, which includes a sintering box 3. A plurality of first guide rollers 31 are arranged in the sintering box 3. The plurality of first guide rollers 31 are arranged at intervals along the conveying direction of the carbon paper, such as, the plurality of first guide rollers 31 are arranged at intervals along the conveying direction of the carbon paper 10.
[0074] Optionally, the conveying direction of the carbon paper 10 in the sintering box 3 is a horizontal direction; of course, in other embodiments, the conveying direction of the carbon paper 10 in the sintering box 3 may also be an inclined direction.
[0075] When the dried carbon paper 10 enters the sintering box 3 , the first guide rollers 31 can transport the carbon paper 10 along the transport direction of the carbon paper 10 so that the carbon paper 10 is output from the sintering box 3 after sintering.
[0076] Furthermore, in order to prevent the carbon paper 10 from sagging due to an excessively large gap between two adjacent first guide rollers 31 , a first support roller 32 is provided between the two adjacent first guide rollers 31 .
[0077] Specifically, the upper opening 213 of the drying box 21 faces upward, while the sintering box entrance of the sintering box 3 faces horizontally, with a height difference between the two. To ensure that the carbon paper 10 discharged from the upper opening 213 of the drying box 21 can smoothly enter the sintering box 3, the carbon paper hydrophobic treatment equipment is further provided with a third guide roller assembly between the upper opening 213 of the drying box 21 and the sintering box entrance of the sintering box 3. The third guide roller assembly includes at least two third guide rollers 61 spaced apart along an oblique direction. The highest point of the third guide roller 61 adjacent to the first guide roller 31 is aligned with the highest point of the first guide roller 31. The third guide roller 61 adjacent to the upper opening 213 of the drying box 21 is tangent to the extension line of the carbon paper within the drying box 21.
[0078] It should be noted that the inclined direction refers to a direction that is at a certain angle to the horizontal direction but is not perpendicular to the horizontal direction.
[0079] It is understandable that the hydrophobic liquid on the carbon paper 10 output from the drying box 21 has dried. When the carbon paper 10 contacts the third guide roller 61 , the hydrophobic liquid on the carbon paper 10 will not stick to the third guide roller 61 and contaminate the third guide roller 61 .
[0080] Specifically, an upper air chamber 33 and a lower air chamber 34 are further provided in the sintering box 3 . The upper air chamber 33 is located above the first guide roller 31 , and the lower air chamber 34 is located below the first guide roller 31 .
[0081] When the carbon paper 10 enters the sintering box 3 horizontally, the upper air chamber 33 blows sintering air toward the upper surface of the carbon paper 10, and the lower air chamber 34 blows sintering air toward the lower surface of the carbon paper 10, thereby completing the sintering process of the carbon paper 10 and making the hydrophobic liquid firmly adhere to the carbon paper 10.
[0082] Specifically, the temperature of the sintering air blown out from the upper air chamber 33 and the lower air chamber 34 is not lower than 350°C, such as 350°C, 400°C or 450°C.
[0083] Specifically, a return air plate 35 and a second heating pack are provided in the sintering box 3. The sintering air blown out from the upper air chamber 33 and the lower air chamber 34 blows toward the carbon paper 10, then returns to the second heating pack through the return air plate 35, and is heated again in the second heating pack before being blown out through the upper air chamber 33 and the lower air chamber 34.
[0084] Furthermore, after the sintering process of the carbon paper 10 is completed, the carbon paper 10 needs to be cooled before being output from the carbon paper hydrophobic treatment device.
[0085] In order to complete the cooling process of the sintered carbon paper 10, see Figure 4 In this embodiment, the carbon paper hydrophobic treatment equipment also includes a cooling device, which includes a cooling box 5. The cooling box 5 is connected to the outlet of the sintering box 3. A plurality of second guide rollers 51 are arranged in the cooling box 5. The plurality of second guide rollers 51 in the cooling box 5 are arranged at intervals along the conveying direction of the carbon paper 10, such as the plurality of second guide rollers 51 are arranged at intervals along the horizontal direction.
[0086] Optionally, in the cooling box 5 , the conveying direction of the carbon paper 10 can be a horizontal direction or an inclined direction.
[0087] The carbon paper 10 output from the sintering box 3 is transported by the second guide roller 51 and moves in the cooling box 5 , so as to complete cooling of the carbon paper 10 in the cooling box 5 .
[0088] Specifically, a third air nozzle group and a fourth air nozzle group are provided in the cooling box 5 , which are spaced apart from each other. The third air nozzle group is located on the upper side of the second guide roller 51 , and the fourth air nozzle group is located on the lower side of the second guide roller 51 .
[0089] The third nozzle group blows air toward the upper surface of the carbon paper 10 , and the fourth nozzle group blows air toward the lower surface of the carbon paper 10 , thereby completing cooling of the carbon paper 10 .
[0090] Specifically, the third nozzle group includes a plurality of third nozzles 52 arranged in sequence along the conveying direction of the carbon paper 10, and the plurality of third nozzles 52 blow air together toward the upper surface of the carbon paper 10; the fourth nozzle group includes a plurality of fourth nozzles 53 arranged in sequence along the conveying direction of the carbon paper 10, and the plurality of fourth nozzles 53 blow air together toward the lower surface of the carbon paper 10.
[0091] Furthermore, an air outlet plate is provided on the side wall of the cooling box 5, and an air outlet hole connected to the outside is provided on the air outlet plate. The cool air blown out by the third air nozzle 52 and the fourth air nozzle 53 passes through the carbon paper 10 and then flows out from the air outlet hole.
[0092] Specifically, the third air nozzle 52 and the fourth air nozzle 53 can obtain external air through a fan. The temperature of the external air is relatively low. After the third air nozzle 52 and the fourth air nozzle 53 directly obtain the external air, they blow the external air directly toward the carbon paper 10 to cool the carbon paper 10.
[0093] Furthermore, in order to discharge the waste gas generated after sintering and cooling the carbon paper 10, in this embodiment, the carbon paper hydrophobic treatment equipment also includes a waste gas exhaust pipe 4, and the sintering box 3 and the cooling box 5 are both connected to the waste gas exhaust pipe 4.
[0094] For example, in a preferred embodiment of the present application, the working process of the carbon paper hydrophobic treatment equipment is as follows:
[0095] The carbon paper 10 enters the hydrophobic box 11 via the guide roller 12 and is fully soaked in the hydrophobic liquid along the pressure roller assembly in the hydrophobic box 11;
[0096] The carbon paper 10 is then transported from the carbon paper outlet 111 of the hydrophobic tank 11 to the plucking roller set 13. The two plucking rollers 131 squeeze the carbon paper 10 to squeeze out excess hydrophobic liquid on the carbon paper 10.
[0097] The carbon paper 10 then enters the drying box 21 vertically from the lower opening 212 of the drying box 21. Inside the drying box 21, the first air nozzle 22 and the second air nozzle 23 blow air toward the carbon paper 10, completing the drying process of the carbon paper 10.
[0098] The carbon paper 10 is then output from the upper opening 213 of the drying box 21 and enters the sintering box 3 via the third guide roller set. Under the action of the upper air chamber 33 and the lower air chamber 34 in the sintering box 3, the carbon paper 10 completes the sintering process.
[0099] Finally, the carbon paper 10 enters the cooling box 5 to complete the cooling process, and the carbon paper 10 that has completed the cooling process is output from the outlet of the cooling box 5 .
[0100] Obviously, the above-described embodiments of the present invention are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the manner in which the present invention is to be implemented. A person skilled in the art would be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is not necessary and impossible to enumerate all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the claims of the present invention.
