Abstract
Description
Technical Field
[0001] This application relates to the technical field of ovens, and in particular to a pre-evaporation oven device for alkaline electrolyzed water hydrogen production diaphragms. Background Art
[0002] During the process of the coater processing the diaphragm, there are processes including spraying liquid on the diaphragm by the nozzle and drying the diaphragm using the oven. In the prior art, after the diaphragm completes the spraying process, the traction device is used to transfer the diaphragm into the oven. Under the action of high-temperature baking, the liquid can be dried and adhered to the diaphragm.
[0003] However, in actual applications, due to the influence of the equipment volume structure between the nozzle and the oven, when the traction device transfers the diaphragm at the nozzle into the oven, impurities carried in the air will be brought into the oven. Under high-temperature baking, the impurities adhere to the liquid and are dried synchronously, which will affect the finished product quality of the diaphragm. In addition, the temperature difference between the inside and outside of the oven is relatively large. When the traction device transfers the diaphragm at the nozzle into the oven, for the diaphragm at the end that enters the oven first, its temperature is rapidly increased, which causes the moisture of the liquid to be rapidly volatilized to form bubbles, ultimately resulting in the integrity of the structure and the bonding structure being affected during the curing process of the liquid, and the finished product quality of the diaphragm is poor. Summary of the Invention
[0004] In order to ensure the quality of the diaphragm during the drying process, this application provides a pre-evaporation oven device for alkaline electrolyzed water hydrogen production diaphragms.
[0005] A pre-evaporation oven device for alkaline electrolyzed water hydrogen production diaphragms provided by this application adopts the following technical solutions:
[0006] A pre-evaporation oven device for alkaline electrolyzed water hydrogen production diaphragms includes a box body. The box body is provided with a feed inlet and a discharge outlet along its transverse direction. Both the feed inlet and the discharge outlet are provided with heat preservation covers, and a warm air component is arranged on the heat preservation covers. The warm air component is used to adjust the temperature of the air in the heat preservation covers.
[0007] By adopting the above technical solutions, heat preservation covers are provided at both the feed inlet and the discharge outlet, and the warm air component can adjust the temperature of the air, enabling the diaphragm to maintain a constant temperature environment when entering and leaving the box body, which helps to reduce the influence of temperature fluctuations on the diaphragm quality and ensure the quality of the diaphragm during the drying process.
[0008] Preferably, the box body is provided with an air inlet and an air outlet along its vertical direction. A heating mechanism is arranged outside the box body. The output end of the heating mechanism is assembled with the air inlet. One end of the air outlet is assembled with the box body and the other end is assembled with the heating mechanism. The heating mechanism is used to provide hot air for the box body, and the circulating cold air flows back from the air outlet to the heating mechanism for circulating heating.
[0009] By adopting the above technical solution, under the action of the heating mechanism, hot air can be provided for the box body, so as to realize the function of heating and drying the diaphragm in the box body. Through the cooperation of the air inlet and the air outlet, the circulation of hot air is realized. The continuous circulation of hot air can maintain a high degree of uniformity of the temperature inside the box body.
[0010] Preferably, a blower is arranged on the heat preservation cover. The blower arranged at the feeding port and the blower arranged at the discharging port are symmetrically arranged along the central line of the length of the box body, and the opening of the blower faces the center of the box body.
[0011] By adopting the above technical solution, blowers are symmetrically arranged at the feeding port and the discharging port, which strengthens the air flow circulation inside the box body, effectively reduces temperature dead angles and humidity accumulation. When the diaphragm enters and exits, the blower can quickly supplement hot air, reduce the temperature fluctuation inside the box body, and ensure the stability and continuity of the pre-evaporation process. At the same time, the blower can stir the air inside the protection cover to make the air flow more strongly, so as to reduce the attachment of impurities on the diaphragm and help improve the finished product quality of the diaphragm.
[0012] Preferably, a heat insulation pad is arranged on the inner wall of the box body.
[0013] By adopting the above technical solution, the heat insulation pad has good heat insulation function, can effectively reduce the heat exchange between the box body and the outside world, helps improve the thermal efficiency and service life of the oven, reduces the situation that the operator is scalded by high temperature due to accidentally touching the box body, and helps improve the safety of the equipment.
[0014] Preferably, a plurality of keel frames are arranged between the heat insulation pad and the box body, and the plurality of keel frames are equidistantly distributed along the inner wall of the box body.
[0015] By adopting the above technical solution, the plurality of equidistantly distributed keel frames can, on the one hand, enhance the structural stiffness of the heat insulation pad so that the heat insulation pad is not easily deformed, and on the other hand, can make the heat insulation pad fit more firmly on the inner wall of the box body, further enhancing the stability and durability of the heat insulation layer, helping to make the heat inside the box body more evenly distributed to avoid the appearance of hot spots and cold spots, and ensuring the uniformity of the pre-evaporation process.
[0016] Preferably, the height dimension of the keel frame is smaller than the height dimension of the heat insulation pad, and the keel frame is completely buried on the side of the heat insulation pad close to the box body.
[0017] By adopting the above technical solution, the keel frame is completely buried in the heat insulation pad, which can reduce the heat bridge effect between the heat insulation pad and the box body, further improve the heat insulation performance. In addition, since the height of the keel frame is less than that of the heat insulation pad and there is no protruding part, the risk of damage to the diaphragm caused by hitting sharp objects during the transportation of the diaphragm in the box body can be reduced.
[0018] Preferably, a flattening roller is transversely arranged inside the box body along its transverse direction, and the diaphragm passes through the feeding port and is transported to the discharging port through the flattening roller.
[0019] By adopting the above technical solution, the setting of the flattening roller enables the diaphragm to be evenly flattened during the drying process, so as to avoid the generation of wrinkles and bubbles, thereby effectively improving the product quality. At the same time, it can make the diaphragm be transported smoothly, reduce the possibility of production interruption, ensure the continuity of the production process, and thus improve the production efficiency.
[0020] Preferably, a heat insulation pad is arranged on the inner wall of the heat preservation cover.
[0021] By adopting the above technical solution, the setting of the heat insulation pad can enhance the heat insulation performance of the heat preservation cover, reduce heat loss, contribute to improving energy efficiency and reducing energy consumption. At the same time, to a certain extent, it can reduce the impact of heat radiation on the surrounding environment, thereby further improving the operation safety.
[0022] In summary, the present application includes at least one of the following beneficial technical effects:
[0023] 1. Warm air components are arranged on the heat preservation covers of both the feeding port and the discharging port. The warm air components can adjust the temperature of the air, so that the diaphragm can maintain a constant temperature environment when entering and leaving the box body, which helps to reduce the impact of temperature fluctuations on the quality of the diaphragm and ensure the quality of the diaphragm during the drying process;
[0024] 2. Multiple equally spaced keel frames can, on the one hand, enhance the structural stiffness of the heat insulation pad, making the heat insulation pad not easily deformed, and on the other hand, enable the heat insulation pad to fit more firmly on the inner wall of the box body, further enhancing the stability and durability of the heat insulation layer, helping to make the heat inside the box body more evenly distributed, so as to avoid the appearance of hot spots and cold spots, and ensure the uniformity of the pre-evaporation process;
[0025] 3. The keel frame is completely buried in the heat insulation pad, which can reduce the heat bridge effect between the heat insulation pad and the box body, further improve the heat insulation performance.

[0029] The following Figure 1-2 further elaborates on the present application in conjunction with the attached drawings.
[0030] An embodiment of the present application discloses a pre-evaporation oven device for an alkaline electrolyzed water hydrogen production diaphragm.
[0031] Referring to Figure 1 and Figure 2 , a pre-evaporation oven device for an alkaline electrolyzed water hydrogen production diaphragm includes a box body 1. An air inlet 2 and an air outlet 3 are arranged vertically on the box body 1. A heating mechanism 6 is arranged outside the box body 1. The output end of the heating mechanism 6 is assembled with the air inlet 2. One end of the air outlet 3 is assembled with the box body 1 and the other end is assembled with the heating mechanism 6. The heating mechanism 6 is used to provide hot air for the box body 1, and the circulating cold air returns from the air outlet 3 to the heating mechanism 6 for circulating heating.
[0032] In the present application, the heating mechanism 6 is a gas engine. When starting the heating mechanism 6, the circulating cold air at the air outlet 3 can be heated, or the air drawn in from the outside to the heating mechanism 6 can be heated, so as to continuously provide hot air for the box body 1 and be able to heat and dry the diaphragm that subsequently enters the box body 1.
[0033] Referring to Figure 1 and Figure 2 , a feed inlet 4 and a discharge outlet 5 are arranged horizontally on the box body 1. A flattening roller 7 is arranged horizontally inside the box body 1. The diaphragm passes through the feed inlet 4 and is transported to the discharge outlet 5 through the flattening roller 7. Under the action of the flattening roller 7, the diaphragm is transported smoothly, reducing the possibility of production interruption, ensuring the continuity of the production process, and at the same time enabling the diaphragm to be evenly flattened during the drying process to avoid the generation of wrinkles and bubbles, thereby improving production efficiency and production quality.
[0034] More specifically, referring to Figure 1 and Figure 2 , a heat insulation pad 8 is arranged on the inner wall of the box body 1. The heat insulation pad 8 has good heat insulation function, which can effectively reduce the heat exchange between the box body 1 and the outside, contribute to improving the thermal efficiency and service life of the oven, reduce the situation that the operator is scalded by high temperature due to accidentally touching the box body 1, and thus improve the safety of the equipment.
[0035] A plurality of keel frames 9 are arranged between the heat insulation pad 8 and the box body 1, and the plurality of keel frames 9 are equidistantly distributed along the inner wall of the box body 1 to enhance the structural stiffness of the heat insulation pad 8, so that the heat insulation pad 8 is not easily deformed, and the heat insulation pad 8 can be more firmly attached to the inner wall of the box body 1, further enhancing the stability and durability of the heat insulation layer, helping to make the heat inside the box body 1 more evenly distributed, so as to avoid the appearance of hot spots and cold spots, and ensure the uniformity of the pre-evaporation process.
[0036] In this application, the height dimension of the keel frame 9 is smaller than the height dimension of the heat insulation pad 8, and the keel frame 9 is completely buried on the side of the heat insulation pad 8 close to the box body 1, which can reduce the heat bridge effect between the heat insulation pad 8 and the box body 1, and further improve the heat insulation performance. Since the height of the keel frame 9 is smaller than that of the heat insulation pad 8 and there is no protruding part, it can reduce the risk of the diaphragm being damaged when hitting sharp objects during transportation in the box body 1.
[0037] Refer to Figure 1 and Figure 2 , heat preservation covers 10 are arranged at both the feed inlet 4 and the discharge outlet 5. A warm air component is arranged on the heat preservation cover 10, and the warm air component is used to adjust the temperature of the air in the heat preservation cover 10. In this application, the specific structure of the warm air component is not limited, and a warm air blower, a heat exchange plate, etc. can be adopted. It is required that the warm air blower can realize the temperature adjustment function for the air, so that the diaphragm can maintain a constant temperature environment when entering and leaving the box body 1, which helps to reduce the influence of temperature fluctuation on the quality of the diaphragm and ensure the quality of the diaphragm during the drying process.
[0038] This application provides another preferred solution. Instead of setting a warm air component separately, the entire box body 1 is heated by a heating mechanism 6. A ventilation pipe is connected between the box body 1 and the heat preservation cover 10, so that the hot air heated by the heating mechanism 6 can also be transmitted into the heat preservation cover to achieve the heat preservation effect of the heat preservation cover.
[0039] A blower is arranged on the heat preservation cover 10. The blower arranged at the feed inlet 4 and the blower arranged at the discharge outlet 5 are symmetrically arranged along the length center line of the box body 1, and the opening of the blower faces the center of the box body 1.
[0040] In specific applications, the operator starts the warm air component or the heating mechanism 6. The warm air blower heats the air inside the heat preservation cover 10. Under the action of the blower, the blower can quickly supplement hot air, strengthen the air flow circulation inside the box body 1, effectively reduce temperature dead zones and humidity accumulation. When the diaphragm enters and exits, a certain temperature is always maintained inside the heat preservation cover 10, reducing the temperature difference between the heat preservation cover 10 and the box body 1, reducing the temperature fluctuation inside the box body 1, and ensuring the stability and continuity of the pre-evaporation process. Since the blower can stir the air inside the protective cover, making the air flow more strongly, impurities adhering to the diaphragm are reduced, which helps to improve the finished product quality of the diaphragm.
[0041] In this application, a heat preservation pad is provided on the inner wall of the heat preservation cover 10 to enhance the heat preservation performance of the heat preservation cover 10, reduce heat loss, help improve energy efficiency and reduce energy consumption. At the same time, to a certain extent, the impact of thermal radiation on the surrounding environment can be reduced, thereby further improving the operation safety.
[0042] The above are all the preferred embodiments of this application. This embodiment is only an explanation of this application and does not limit the protection scope of this application accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
