[0004] To achieve the above purpose, the drying device proposed in this application includes:

[0005] An oven, wherein the oven is provided with an air inlet;

[0006] An air inlet pipe, the air inlet pipe is connected to the air inlet port, and the air inlet pipe is provided with an inlet port;

[0007] A humidifying mechanism, the humidifying mechanism comprises a steam generator and a connecting pipe, the steam generator is provided with a steam outlet, the connecting pipe connects the steam outlet and the air inlet pipe, and the connecting pipe is connected to one end of the air inlet pipe and is staggered with the inlet; and

[0008] The regulating structure is configured to adjust the ratio of natural air and steam in the air inlet duct.

[0009] The drying device of the technical solution of the present application is provided with a humidifying mechanism connected to the air inlet pipe, so that the steam generated by the steam generator in the humidifying mechanism can enter the air inlet pipe through the connecting pipe to mix with the natural air entering from the air inlet pipe. At the same time, it is further provided with an adjusting structure, through which the ratio of natural air and steam in the air inlet pipe can be adjusted to compensate for the humidity in the natural air. Then, after the mixed airflow of steam and natural air further enters the oven through the air inlet pipe, the humidity in the oven can be compensated and adjusted, so that the humidity in the oven can be stably maintained within a preset range, so that the dried items can be dried uniformly. Therefore, the structural optimization design of the drying device in the present solution realizes the adjustable humidity in the drying device, which can improve the uniformity of the drying of the dried items by the drying device and reduce the possibility of defects in the dried items. Moreover, the steam generator in the humidifying mechanism of the drying device in the present solution is also arranged to be connected to the air inlet pipe through the connecting pipe, and the position where the connecting pipe is connected to the air inlet pipe and the inlet of the air inlet pipe are staggered. In this way, natural air and steam can flow in from the inlet of the air inlet pipe and the connecting pipe respectively. In other words, natural air and steam can enter through two separate independent flow paths and then mix. At this time, it is convenient to control the delivery of natural air and steam separately on the two separate independent flow paths, so as to improve the diversity of humidity adjustment in the drying device.

[0010] Optionally, the steam generator comprises:

[0011] A liquid storage container, the liquid storage container is provided with a liquid storage cavity and a steam outlet, the steam outlet is connected to the liquid storage cavity; and

[0012] An air guide tube, one end of which is inserted into the liquid storage cavity of the liquid storage container and is configured to introduce gas into the liquid contained in the liquid storage cavity.

[0013] In this way, relatively fine steam droplets can be produced, so that they will not be vaporized and absorb heat in the oven, and will not disturb the wind field and temperature in the oven.

[0014] Optionally, the steam generator further comprises a first heating module, the first heating module is configured to heat the liquid contained in the liquid storage chamber, and the first heating module is formed as an adjustment structure.

[0015] Thus, the temperature of the liquid can be adjusted and the saturated vapor pressure can be adjusted to achieve the adjustment of the water content in the vapor.

[0016] Optionally, the liquid storage container is made of a heat-conducting material, and the first heating module is disposed on the outside of the liquid storage container.

[0017] In this way, the first heating module can heat the liquid in the liquid storage chamber, and at the same time, the arrangement of the first heating module will not be affected by the liquid in the liquid storage container, thereby improving the convenience of installing and setting the first heating module.

[0018] Optionally, the liquid storage container comprises:

[0019] an inner container having a liquid storage chamber and a vapor outlet; and

[0020] The outer container is sleeved on the outer side of the inner container and is enclosed with the inner container to form a medium cavity, and the medium cavity is configured to accommodate liquid heat-conducting medium.

[0021] In this way, the uniformity of heating by the first heating module can be improved, so as to stably control the water content in the steam and improve the stability of humidity regulation in the oven.

[0022] Optionally, one end of the inner container provided with a steam outlet protrudes from the outer container, and the air guide pipe is provided through the inner container located outside the outer container;

[0023] And / or, the first heating module is installed on the outer container.

[0024] Thus, the end of the inner container with the steam outlet is arranged to protrude, which can improve the convenience of installing the connecting pipe. The first heating module is installed on the outer container, so that the installation position provided by the outer container can be directly used, so as to simplify the number of parts of the drying device.

[0025] Optionally, the first heating module is an electric heating element.

[0026] In this way, the temperature of the first heating module can be easily controlled and adjusted, while being clean and environmentally friendly; and the convenience of its installation and setting is improved.

[0027] Optionally, the drying device further comprises a temperature sensor, and the temperature sensor is configured to detect the temperature of the liquid contained in the liquid storage chamber;

[0028] The drying device also includes a controller, which is electrically connected to the temperature sensor and the first heating module.

[0029] Therefore, the temperature of the liquid in the liquid storage chamber can be detected by the temperature sensor, so that the controller can control the working state of the first heating module, and then the saturated vapor pressure can be more accurately controlled and adjusted, thereby achieving control and adjustment of the water content in the vapor and achieving more accurate control and adjustment of the humidity in the oven.

[0030] Optionally, at least a portion of the temperature sensor is disposed in the liquid storage cavity.

[0031] Thereby, the accuracy of the detection result of the temperature sensor can be improved.

[0032] Optionally, the drying device further comprises a humidity sensor, at least part of which is disposed in the oven;

[0033] The drying device also includes a controller, which is electrically connected to the humidity sensor and the first heating module.

[0034] Therefore, the humidity in the oven can be detected by the humidity sensor so that the controller can control the working state of the first heating module, and then more accurately control and adjust the saturated steam pressure, thereby achieving control and adjustment of the water content in the steam and more accurately controlling and adjusting the humidity in the oven.

[0035] Optionally, the oven is further provided with an air return port, and at least part of the humidity sensor is provided at the air return port;

[0036] The drying device also includes a return air duct, which is connected to the return air port and the air inlet duct.

[0037] As a result, the humidity value measured by the humidity sensor is the humidity value of the drying airflow fully mixed in the oven, which can improve the accuracy of humidity detection in the oven.

[0038] Optionally, the drying device further comprises a proportional regulating valve, which is arranged on and connected to the air inlet pipe, and one end of the connecting pipe away from the steam outlet is connected to the proportional regulating valve, and the regulating valve is formed as a regulating structure.

[0039] Thereby, the ratio of steam to natural air can be adjusted so as to adjust the humidity in the mixed gas of steam and natural air.

[0040] Optionally, the drying device further comprises a humidity sensor, at least part of which is disposed in the oven;

[0041] The drying device also includes a controller, which is electrically connected to the proportional regulating valve and the humidity sensor.

[0042] Therefore, the humidity in the oven can be detected by the humidity sensor so that the controller can control the working state of the proportional control valve, and then the ratio of steam and natural air can be adjusted more accurately to achieve more accurate control and regulation of the humidity in the oven.

[0043] Optionally, the drying device further comprises a buffer tank, which is arranged on the air inlet pipe and communicated with the air inlet pipe, and the buffer tank is located downstream of the communicating pipe;

[0044] And / or, the drying device further includes a second heating module, which is configured to heat the airflow passing through the air inlet pipe, and the second heating module is located downstream of the connecting pipe.

[0045] Thus, the buffer tank can buffer the airflow, so that the steam flowing out of the connecting pipe and the natural air in the air inlet pipe can be mixed more evenly, thereby improving the uniformity of the humidity of the airflow. By setting up the second heating module, the mixed airflow of steam and natural air can be heated to reach a preset temperature, thereby achieving the drying of the items to be dried in the oven after entering the oven.

[0046] Optionally, when the drying device includes a buffer tank and a second heating module, the second heating module is located downstream of the buffer tank.

[0047] As a result, the second heating module can heat the mixed airflow of the evenly mixed steam and natural air, thereby improving the uniformity and accuracy of the temperature of the mixed airflow.

[0048] Optionally, the drying device further includes a fan, which is disposed in and connected to the air inlet duct, and the air inlet duct is located between the buffer tank and the second heating module.

[0049] In this way, the impact of steam in the airflow on the life of the fan can be reduced, and at the same time, the impact of excessively high temperature in the airflow on the life of the fan can be reduced.

[0050] Optionally, the second heating module is a heat exchanger and is connected to the air inlet pipe;

[0051] Alternatively, the second heating module is an electric heating element and is arranged on the outside of the air inlet duct.

[0052] Therefore, setting the second heating module as a heat exchanger can have a larger heat exchange area, which is beneficial to improve the heating effect of the airflow in the air inlet pipe. Setting the second heating module as an electric heating element can simplify the number of parts of the drying device.

[0053] Optionally, the oven is further provided with an air return port, and the drying device further comprises an air return duct, which is connected to the air return port and the air inlet duct.

[0054] In this way, the drying airflow can be reused.

[0055] Optionally, the drying device further comprises a fan, which is arranged in the air inlet pipe and connected with the air inlet pipe, the fan is located downstream of the connecting pipe, and one end of the return air pipe away from the return air outlet is connected with the fan;

[0056] And / or, the drying device further comprises a buffer tank, the buffer tank is arranged at the air inlet pipe and communicated with the air inlet pipe, and the buffer tank is located between the connecting pipe and the return air pipe;

[0057] And / or, the drying device further includes a second heating module, which is disposed in the air inlet duct and configured to heat the airflow passing through the air inlet duct, and the second heating module is located downstream of the return air duct.

[0058] Thus, by setting a fan, the natural air entering from the air inlet pipe, the steam in the connecting pipe, and the return air flow in the return air pipe can be driven at the same time, so as to simplify the number of parts of the drying device. The buffer tank can buffer the airflow, so that the steam flowing out of the connecting pipe and the natural air in the air inlet pipe can be mixed more evenly, thereby improving the uniformity of the humidity of the airflow. By setting a second heating module, the mixed airflow of steam and natural air can be heated to reach a preset temperature, so as to achieve drying of the items to be dried in the oven after entering the oven.

[0059] Optionally, the oven is extended along the first direction, and the air inlet and the air return outlet are respectively arranged at two ends of the oven in the first direction.

[0060] As a result, the drying airflow can have a relatively long flow path in the drying oven, which is beneficial to prolong the drying action time of the drying airflow and improve the utilization effect of the drying airflow.

[0061] Optionally, the oven has a first side and a second side opposite to each other in a second direction intersecting the first direction, and the air inlet and the air return port are respectively arranged on the first side and the second side;

[0062] And / or, the oven is further provided with a dehumidification port, and the dehumidification port and the return air port are located at the same end of the oven and are respectively located at two opposite sides or two adjacent sides of the oven.

[0063] Thus, by arranging the air inlet and the air return outlet on the first side and the second side respectively, the flow path of the drying airflow in the oven can be further extended so that the drying airflow can fully dry the drying objects. The dehumidification outlet is arranged to facilitate the discharge of moisture after drying the drying objects, so as to better control the humidity in the oven. Further, by arranging the dehumidification outlet and the air return outlet at the same end of the oven and at opposite sides or adjacent sides of the oven respectively, the possibility of the drying airflow entering the air inlet directly flowing out from the dehumidification outlet can be reduced.

[0064] The present application also proposes a battery production system, comprising the above-mentioned drying device. BRIEF DESCRIPTION OF THE DRAWINGS

[0076] At present, from the perspective of market development, power batteries are being used more and more widely. Specifically, power batteries are not only used in energy storage power systems such as hydropower, thermal power, wind power and solar power stations, but are also widely used in electric vehicles such as electric bicycles, electric motorcycles, electric cars, as well as military equipment and aerospace and other fields. With the continuous expansion of the application field of power batteries, the market demand is also constantly expanding.

[0077] The production process of power batteries usually includes the following steps: the first step is electrode slurry preparation, which mainly involves mixing electrode active materials, binders, solvents, etc. together, and forming a slurry after sufficient stirring and dispersion; the second step is coating, which involves evenly coating the slurry prepared in the first step on the current collector with a specified thickness, and drying the solvent; the third step is electrode punching, which involves punching the electrode sheets produced in the previous step into specified sizes and shapes; the fourth step is lamination or winding, which involves assembling the positive and negative electrode sheets and diaphragms together, and forming an electrode core after gluing; the fifth step is battery assembly, which involves installing the electrode core produced in the previous step into a shell with a punched cavity, and completing top sealing, side sealing, etc. (with a reserved injection port) to form an uninjected battery; the sixth step is injection, which involves injecting a specified amount of electrolyte into the battery device; the seventh step is battery sealing, which involves extracting the gas inside the battery device in a vacuum environment and completing the sealing.

[0078] Among them, in the actual production of drying the electrode through a drying device after coating, it will be affected by changes in environmental humidity, and the drying device in the related technology cannot adjust the humidity, which makes the electrode prone to uneven drying and cracking and other undesirable phenomena.

[0079] Therefore, based on the above considerations, in order to solve the problem that the drying device in the related art cannot adjust the humidity, which makes it easy to cause uneven drying of the electrode piece and cause cracking of the electrode piece, the present application proposes a new drying device. The drying device is innovatively provided with a humidifying mechanism connected to the air inlet pipe, so that the steam generated by the steam generator in the humidifying mechanism enters the air inlet pipe through the connecting pipe and mixes with the natural air, so as to achieve compensatory adjustment of the humidity in the oven, so that the humidity in the oven can be stably maintained within a preset range, so that the electrode piece can be evenly dried and the possibility of cracking and other adverse phenomena can be reduced.

[0080] In addition, it should be noted that the drying device proposed in the present application can be used to dry the electrode pieces after coating, such as anode pieces or cathode pieces; of course, it can also be used to dry the diaphragm after coating. It can be seen that the present application does not limit the type of the drying device to be dried.

[0081] Next, the structure of the drying device proposed in this application is explained by an embodiment:

[0082] Please refer to Figure 1 In one embodiment of the present application, the drying device 100 proposed in the present application includes a drying oven 10, an air inlet pipe 20, a humidifying mechanism 30 and an adjusting structure; the drying oven 10 is provided with an air inlet 121; the air inlet pipe 20 is connected to the air inlet 121, and the air inlet pipe 20 is provided with an inlet 21; the humidifying mechanism 30 includes a steam generator 31 and a connecting pipe 33, the steam generator 31 is provided with a steam outlet 3113, and the connecting pipe 33 connects the steam outlet 3113 and the air inlet pipe 20; the adjusting structure is configured to adjust the ratio of natural air and steam in the air inlet pipe 20.

[0083] The oven 10 can be used to form a drying chamber 111 to provide a drying environment for the dried items. The shape of the oven 10 can be a cuboid, a cube, or a cylinder, etc. The present application does not limit the shape of the oven 10.

[0084] The shape of the drying chamber 111 can be set to be the same as the shape of the oven 10, for example, both are set to be a rectangular parallelepiped. Of course, the shape of the drying chamber 111 can also be set to be different from the shape of the oven 10. In addition, in order to realize that the drying device 100 can perform transmission-type drying on the dried items and improve the drying efficiency, the drying device 100 can also include a transmission mechanism. At this time, the oven 10 can be provided with an input port and an output port, and the input port and the output port are both connected to the drying chamber 111. The transmission mechanism can be used to transport the items to be dried from the input port to the drying chamber 111, and then output them from the output port. Among them, the transmission mechanism can be a belt conveyor mechanism or a roller conveyor mechanism, and the present application does not limit the structural type of the transmission mechanism.

[0085] The air inlet 121 can be used to communicate with the air inlet pipe 20 so that the airflow with a drying effect can enter the drying chamber 111 of the oven 10 to dry the items to be dried in the oven 10. The air inlet 121 can be located at the same end as the input port for the items to be dried that is provided on the oven 10 as described above. Of course, the air inlet 121 and the input port can also be located at opposite ends of the oven 10, and the relative positions of the air inlet 121 and the input port are not limited in this application. In addition, the shape of the air inlet 121 can be set to be the same as the cross-sectional shape of the air inlet pipe 20, for example, both are circular, so as to improve the adaptability of the two to be connected. In addition, the oven 10 can include a main body box 11 and an air inlet cylinder 12 protruding from the outside of the main body box 11, and the air inlet cylinder 12 is connected to the main body box 11. At this time, the air inlet 121 can be formed by enclosing the inner side of the air inlet cylinder 12. In this way, the air inlet 12 is convenient for connecting the connection position and the air inlet pipe 20, which is conducive to improving the convenience of connecting the air inlet pipe 20 and the oven 10. Furthermore, in the air inlet direction of the air inlet 121, the air inlet 12 can be further set to a flared shape to improve the air passing efficiency of the air inlet 12. Of course, in other embodiments, the oven 10 can also include only the main box 11. In this case, an opening can be directly opened on the main box 11 to form the air inlet 121.

[0086] The air inlet pipe 20 can be used to connect the outside world and the air inlet 121 on the oven 10, so that the natural air from the outside can enter the drying chamber 111 of the oven 10 through the air inlet pipe 20, and then dry the items to be dried in the oven 10. The air inlet pipe 20 can be opened at both ends to allow the entry of natural air from the outside and to communicate with the air inlet 121. That is, the opening at one end of the air inlet pipe 20 can be formed as an inlet 21 to allow the entry of natural air from the outside; the opening at the other end can be formed as an outflow port to communicate with the air inlet 121. At this time, the structure of the air inlet pipe 20 can be simplified and the convenience of its processing and manufacturing can be improved. In addition, the air inlet pipe 20 can be a hose, or a hard pipe, or part of it can be a hose and the other part can be a hard pipe. The present application does not limit the type of the air inlet pipe 20. In addition, the air inlet pipe 20 can be extended along a straight line, or along a fold line, or along an arc line, etc., and the present application does not limit the shape of the air inlet pipe 20. The cross-sectional shape of the air inlet pipe 20 can be circular, or square or rectangular, etc., and the present application does not limit the cross-sectional shape of the air inlet pipe 20.

[0087] The steam generator 31 can be used to generate steam. The steam generator 31 can include a liquid storage container 311 and an air guide pipe 313 as described below. Of course, the steam generator 31 can be a humidifier, and the present application does not limit the structural type of the steam generator 31.

[0088] The steam outlet 3113 can be used to discharge the steam generated by the steam generator 31. The shape of the steam outlet 3113 can be the same as the cross-sectional shape of the connecting port, for example, both are circular, so as to improve the adaptability of the two to be connected. In addition, the steam outlet 3113 can be set at any position of the steam generator 31. For example, when the drying device 100 is in a normal use and installation state, with the ground as a reference, the steam outlet 3113 can be set on the upper wall or side wall of the steam generator 31.

[0089] The connecting pipe 33 can be used to connect the steam outlet 3113 of the steam generator 31 and the air inlet pipe 20, so that the steam generated by the steam generator 31 can enter the air inlet pipe 20 through the connecting pipe 33. Among them, the connecting pipe 33 can be connected to one end of the air inlet pipe 20 near the air inlet 121, so that the subsequent steam and the natural air entering the air inlet pipe 20 can be fully mixed on the subsequent air inlet pipe 20 to improve the uniformity of the humidity in the mixed air flow. In addition, the connecting pipe 33 can be opened at both ends to communicate with the steam outlet 3113 and the air inlet pipe 20 respectively. At this time, the structure of the connecting pipe 33 can be simplified to improve the convenience of its processing and manufacturing. In addition, the connecting pipe 33 can be a hose, of course, it can also be a hard pipe, or part of it is a hose and the other part is a hard pipe. The present application does not limit the type of the connecting pipe 33. In addition, the connecting pipe 33 can be extended along a straight line, of course, it can also be extended along a folded line, or it can be extended along an arc, etc., and the present application does not limit the shape of the connecting pipe 33. The cross-sectional shape of the connecting pipe 33 may be circular, or may be square or rectangular, etc. The present application does not limit the cross-sectional shape of the connecting pipe 33 .

[0090] The regulating structure can be used to adjust the ratio of natural air and steam in the air inlet pipe 20, and then adjust the humidity in the oven 10 by different steam contents in the mixed airflow formed by the mixing of natural air and steam. Wherein, when the steam generator 31 is configured to include a liquid storage container 311 and an air duct 313, the regulating structure can be composed of a first heating module 315 as described below, so as to adjust the amount of steam by heating the first heating module 315 to different temperatures, thereby adjusting the ratio of natural air and steam. Alternatively, the regulating structure can also be composed of a blower connected to the air inlet of the air duct 313, so as to adjust the amount of steam generated in the subsequent liquid storage container 311 by adjusting the blast volume. Alternatively, the regulating structure can also be a proportional regulating valve 80 provided at the connection point between the connecting pipe 33 and the air inlet pipe 20 as described below. Alternatively, when the steam generator 31 is a humidifier, the regulating structure can be composed of a humidification gear on the humidifier that controls the jet size. It can be seen that the present application does not limit the structural type of the regulating structure, and it can be composed of one or at least two of the above-mentioned structures.

[0091] The drying device 100 of the technical solution of the present application is provided with a humidifying mechanism 30 connected to the air inlet pipe 20, so that the steam generated by the steam generator 31 in the humidifying mechanism 30 can enter the air inlet pipe 20 through the connecting pipe 33 to mix with the natural air entering from the air inlet pipe 20. At the same time, it is further provided with an adjustment structure, through which the ratio of the natural air and steam in the air inlet pipe 20 can be adjusted to compensate for the humidity in the natural air. After the mixed airflow of steam and natural air further enters the drying chamber 111 of the oven 10 through the air inlet pipe 20, the humidity in the oven 10 can be compensated and adjusted, so that the humidity in the oven 10 can be stably maintained within a preset range, so that the objects to be dried can be uniformly dried. Therefore, the structural optimization design of the drying device 100 in the present solution realizes that the humidity in the drying device 100 can be adjusted, which can improve the uniformity of the drying of the objects to be dried by the drying device 100 and reduce the possibility of defects in the objects to be dried. Moreover, the steam generator 31 in the humidifying mechanism 30 of the drying device 100 in this solution is also arranged to be connected to the air inlet pipe 20 through a connecting pipe 33, and the position where the connecting pipe 33 is connected to the air inlet pipe 20 is staggered with the inlet port 21 of the air inlet pipe 20. In this way, natural air and steam can flow in from the inlet port of the air inlet pipe 20 and the connecting pipe 33 respectively. In other words, natural air and steam can enter through two separate independent flow paths and then mix. At this time, it is convenient to control the delivery of natural air and steam separately on the two separate independent flow paths, so as to improve the diversity of humidity regulation in the drying device 100.

[0092] Please refer to Figure 1In one embodiment of the present application, the steam generator 31 includes a liquid storage container 311 and an air duct 313. The liquid storage container 311 is provided with a liquid storage cavity 3112 and a steam outlet 3113. The steam outlet 3113 is connected to the liquid storage cavity 3112. One end of the air duct 313 is passed through the liquid storage cavity 3112 of the liquid storage container 311 and is configured to introduce gas into the liquid contained in the liquid storage cavity 3112.

[0093] The liquid storage container 311 can be used to form a liquid storage cavity 3112 to provide space for accommodating deionized water, ordinary water or other types of liquids. The shape of the liquid storage container 311 can be a rectangular parallelepiped, or a cube or a cylinder, etc., and the present application does not limit the shape of the liquid storage container 311. The material of the liquid storage container 311 can be metal, or plastic, and the present application does not limit the material of the liquid storage container 311. In addition, it should be noted that in order to facilitate the smooth discharge of steam from the steam outlet 3113, the height of the liquid contained in the liquid storage cavity 3112 needs to be lower than the height of the steam outlet 3113.

[0094] The air guide tube 313 can be used to introduce gas into the liquid in the liquid storage chamber 3112. Among them, the part of the air guide tube 313 located outside the liquid storage container 311 can be formed with an air inlet, and the part located inside the liquid storage chamber 3112 can be formed with an air outlet, and the air outlet extends into the liquid contained in the liquid storage chamber 3112. At the same time, the air guide tube 313 located outside the liquid storage container 311 can also be connected to the blower, so that the blower 103 provides power to drive the gas into the liquid contained in the liquid storage chamber 3112 through the air guide tube 313. In addition, the air guide tube 313 can be a hose, of course, it can also be a hard tube, or part of it can be a hose and the other part can be a hard tube. The present application does not limit the type of the air guide tube 313. In addition, the air guide tube 313 can be set to extend along a straight line, of course, it can also be set to extend along a fold line, or it can be set to extend along an arc, etc. The present application does not limit the shape of the air guide tube 313. The cross-sectional shape of the air guide tube 313 may be circular, or may be square, rectangular, etc., and the present application does not limit the cross-sectional shape of the air guide tube 313 .

[0095] In this embodiment, the steam generator 31 is provided with a liquid storage container 311 and an air guide pipe 313, so that gas can be passed into the liquid contained in the liquid storage chamber 3112 through the air guide pipe 313 to form bubbles, and then the bubbles will burst when they rise to the liquid surface to form steam, thereby achieving steam generation. At this time, the steam droplets generated by the bursting of the bubbles are relatively small, so that they will not be vaporized and absorb heat in the oven 10 again, and thus will not disturb the wind field and temperature in the oven 10, so as to improve the stability of the drying of the drying device 100 to be dried and further improve the uniformity of the drying of the drying parts to be dried.

[0096] Please refer to Figure 1 In one embodiment of the present application, the steam generator 31 further includes a first heating module 315 , and the first heating module 315 is configured to heat the liquid contained in the liquid storage chamber 3112 .

[0097] The first heating module 315 can be used to heat the liquid in the liquid storage chamber 3112. Among them, the first heating module 315 can be an electric heating element, which heats by heating by electricity. Of course, the first heating module 315 can also be a furnace, which heats by generating heat through flames. Alternatively, the first heating module 315 can also be a chemical material package, which heats by generating heat through chemical reactions. It can be seen that the present application does not limit the structural type of the first heating module 315. In addition, the first heating module 315 can be arranged in the liquid storage chamber 3112, and of course it can also be arranged on the outside of the liquid storage container 311. The present application does not limit the setting position of the first heating module 315.

[0098] In this embodiment, the liquid in the liquid storage chamber 3112 can be heated by the first heating module 315, and the liquid content of the vapor is determined by the saturated vapor pressure, that is, the higher the temperature, the greater the saturated vapor pressure, and the greater the moisture content in the gas. Therefore, the saturated vapor pressure can be adjusted by adjusting the temperature of the liquid by the first heating module 315, so as to adjust the amount of vapor and the moisture content in the vapor, which is conducive to further facilitating the adjustment of the humidity in the oven 10 in a more diversified manner.

[0099] Please refer to Figure 1 In one embodiment of the present application, the liquid storage container 311 is made of a heat-conductive material, and the first heating module 315 is disposed on the outside of the liquid storage container 311 .

[0100] The liquid storage container 311 is made of a heat-conducting material, that is, the liquid storage container 311 can have relatively good heat-conducting performance, for example, the material of the liquid storage container 311 can be stainless steel, carbon steel, aluminum alloy or fiberglass, etc. The first heating module 315 is arranged outside the liquid storage container 311, which means that the first heating module 315 is arranged outside the liquid storage container 311, and the installation object of the first heating module 315 can be the liquid storage container 311, and of course it can also be installed on other objects.

[0101] In this embodiment, the liquid storage container 311 is set to be a heat-conducting material, so that the first heating module 315 can be set outside the liquid storage container 311, so that the liquid storage container 311 can be heated, and then the liquid storage container 311 transfers the heat to the liquid contained in the liquid storage cavity 3112. At this time, on the basis of being able to heat the liquid in the liquid storage cavity 3112 by the first heating module 315, the arrangement of the first heating module 315 can be made not to be affected by the liquid in the liquid storage container 311, which is conducive to improving the convenience of installing and setting the first heating module 315.

[0102] Please refer to Figure 1 In one embodiment of the present application, the liquid storage container 311 includes an inner container 3111 and an outer container 3114. The inner container 3111 is provided with a liquid storage cavity 3112 and a steam outlet 3113. The outer container 3114 is sleeved on the outer side of the inner container 3111 and is configured together with the inner container 3111 to form a medium cavity 3115. The medium cavity 3115 is configured to accommodate a liquid heat-conducting medium.

[0103] The inner container 3111 and the outer container 3114 may be nested, and the two may be spaced apart to enclose a medium cavity 3115. The medium cavity 3115 may be formed by only the outer peripheral surface of the inner container 3111 and the outer container 3114, or by the outer peripheral surface and bottom surface of the inner container 3111 and the outer container 3114, or by the outer peripheral surface, lower surface and upper surface of the inner container 3111 and the outer container 3114. In addition, the liquid heat-conducting medium contained in the medium cavity 3115 may be water or oil.

[0104] In this embodiment, the liquid storage container 311 is configured to include an inner container 3111 and an outer container 3114, and a medium cavity 3115 is formed between the two to accommodate a liquid heat-conducting medium, so that the inner container 3111 can be uniformly heated by a water bath or an oil bath. At this time, it is convenient to more accurately control the heating temperature of the liquid in the liquid storage cavity 3112, and then more accurately control the saturated vapor pressure as described above, so as to stably control the water content in the vapor and improve the stability of the humidity regulation in the oven 10.

[0105] Please refer to Figure 1 In one embodiment of the present application, the inner container 3111 is provided with a steam outlet 3113 at one end protruding from the outer container 3114 , and the air guide tube 313 is passed through the inner container 3111 located outside the outer container 3114 .

[0106] Since the steam outlet 3113 is disposed at the upper end of the inner container 3111 , in other words, the upper end of the inner container 3111 can extend from the upper end of the outer container 3114 .

[0107] In this embodiment, the upper end of the inner container 3111 is convex, so that the steam outlet 3113 can be exposed outside the outer container 3114. At this time, when the connecting pipe 33 and the steam outlet 3113 are connected, the outer container 3114 will not interfere with the setting of the connecting pipe 33, which is conducive to improving the convenience of installing the connecting pipe 33.

[0108] Please refer to Figure 1 In one embodiment of the present application, the first heating module 315 is installed on the outer container 3114.

[0109] In this embodiment, the first heating module 315 is installed on the outer container 3114, so that the outer container 3114 can be directly used to provide a mounting position, which is conducive to simplifying the number of parts of the drying device 100. The first heating module 315 can be installed on the outer container 3114 by bonding or clamping with a clamp, and the present application does not limit the installation method of the first heating module 315 on the outer container 3114.

[0110] In one embodiment of the present application, the first heating module 315 is an electric heating element.

[0111] The electric heating element is an object that can generate heat after being energized. The electric heating element may be a heating wire, a heating tube, or a heating film, etc. The present application does not limit the type of the electric heating element.

[0112] In this embodiment, the first heating module 315 is configured as an electric heating element, which makes it easy to control and adjust the temperature, and is also clean and environmentally friendly. Moreover, the structure of the electric heating element is relatively simple, which can also improve the convenience of its installation and configuration.

[0114] In this embodiment, the temperature of the liquid in the liquid storage chamber 3112 can be detected by the temperature sensor 40, and the temperature signal can be transmitted to the controller 50, so that the controller 50 controls the working state of the first heating module 315, thereby realizing more accurate control and adjustment of the temperature of the liquid in the liquid storage chamber 3112. At this time, the saturated vapor pressure can be more accurately controlled and adjusted, and the water content in the vapor can be controlled and adjusted, thereby realizing more accurate control and adjustment of the humidity in the oven 10.

[0115] Please refer to Figure 1 In one embodiment of the present application, at least a portion of the temperature sensor 40 is disposed in the liquid storage chamber 3112 .

[0116] At least part of the temperature sensor 40 is disposed in the liquid storage cavity 3112 , that is, part of the temperature sensor 40 may be disposed in the liquid storage cavity 3112 , or the entire temperature sensor 40 may be disposed in the liquid storage cavity 3112 .

[0117] In this embodiment, at least a portion of the temperature sensor 40 is disposed in the liquid storage chamber 3112, so that the temperature sensor 40 can be configured to contact the liquid contained in the liquid storage chamber 3112, thereby facilitating improving the accuracy of the temperature detection results of the liquid in the liquid storage chamber 3112.

[0119] At least part of the humidity sensor 60 is disposed in the oven 10, that is, only part of the humidity sensor 60 may be disposed in the oven 10, or the humidity sensor 60 may be disposed in the oven 10. The oven 10 may include an area in the drying chamber 111, an area in the return air port 131, and an area in the dehumidification port 141 as described below. Therefore, the humidity sensor 60 may be disposed in the drying chamber 111, or in the return air port 131, or in the dehumidification port 141.

[0120] In this embodiment, the humidity in the oven 10 can be detected by the humidity sensor 60, and the humidity signal can be transmitted to the controller 50, so that the controller 50 controls the working state of the first heating module 315, and furthermore, the temperature of the liquid in the liquid storage chamber 3112 can be more accurately controlled and adjusted. At this time, the saturated vapor pressure can be more accurately controlled and adjusted, and the water content in the vapor can be controlled and adjusted, and further, the humidity in the oven 10 can be more accurately controlled and adjusted.

[0121] Please refer to Figure 2 In one embodiment of the present application, the oven 10 is further provided with a return air port 131, which is connected to the drying chamber 111, and at least a portion of the humidity sensor 60 is disposed at the return air port 131; the drying device 100 also includes a return air duct 70, which is connected to the return air port 131 and the air inlet duct 20.

[0122] The return air port 131 can be used for the airflow entering from the air inlet 121 to enter the oven 10 to dry the items to be dried, and then enter the air inlet 20 again through the return air port 131 and the return air duct 70. Among them, the shape of the return air port 131 can be set to be the same as the cross-sectional shape of the return air duct 70, for example: both are circular, so as to improve the adaptability of the two docking and connection. In addition, the oven 10 may include a return air cylinder 13 protruding from the outside of the main box 11, and the return air cylinder 13 is connected to the main box 11. At this time, the return air port 131 can be enclosed by the return air cylinder 13. In this way, the connection position and the return air duct 70 are conveniently connected through the return air cylinder 13, which is conducive to improving the convenience of the connection between the return air duct 70 and the oven 10. Further, in the wind direction of the return air port 131, the return air cylinder 13 can be further set to a constricted shape to control the wind size of the return air port 131. Of course, in other embodiments, when the oven 10 only includes the main box 11. At this time, an opening can be directly opened on the main box 11 to form the return air port 131. In addition, the return air port 131 can be respectively arranged at the opposite ends of the oven 10 with the air inlet 121, and of course it can also be arranged on the adjacent two sides. The present application does not limit the relative positions of the return air port 131 and the air inlet 121. In addition, the return air port 131 includes the area inside the return air port 131, for example: the area inside the return air cylinder 13, and of course, the area of ​​the drying chamber 111 adjacent to the return air port 131.

[0123] In this embodiment, the return air port 131 is provided on the oven 10, and the return air duct 70 is provided in cooperation, so that the drying airflow can be reused. At the same time, it is also beneficial to enhance the fluidity of the airflow in the oven 10 and improve the drying effect of the dried items. Furthermore, the humidity sensor 60 is provided at the return air so that the humidity value measured by it is the humidity value of the drying airflow fully mixed in the oven 10, which can improve the accuracy of humidity detection.

[0124] Please refer to Figure 2 In one embodiment of the present application, the drying device 100 further includes a proportional regulating valve 80 , which is disposed on the air inlet pipe 20 and connected to the air inlet pipe 20 , and one end of the connecting pipe 33 away from the steam outlet 3113 is connected to the proportional regulating valve 80 .

[0125] The proportional regulating valve 80 may have two inlet ends and one outlet end, one inlet end and one outlet end may be connected to the air inlet pipe 20, and the other inlet end may be connected to the connecting pipe 33, and when in use, the opening sizes of the two inlet ends may be adjusted respectively.

[0126] In this embodiment, by providing a ratio regulating valve 80, the ratio of steam to natural air can be adjusted so as to adjust the humidity in the mixed gas of steam and natural air.

[0127] Please refer to Figure 2 In one embodiment of the present application, the drying device 100 also includes a humidity sensor 60, at least part of which is disposed in the oven 10; the drying device 100 also includes a controller 50, which is electrically connected to the proportional control valve 80 and the humidity sensor 60.

[0128] In this embodiment, the humidity in the oven 10 can be detected by the humidity sensor 60, and the humidity signal can be transmitted to the controller 50, so that the controller 50 controls the working state of the proportional control valve 80, and then the ratio of steam and natural air can be more accurately adjusted to achieve more accurate control and adjustment of the humidity in the oven 10. Of course, in order to further improve the accuracy and diversity of the humidity control and adjustment in the oven 10, in one embodiment, the first heating module 315, the temperature sensor 40, the humidity sensor 60 and the controller 50 can be set at the same time, so that the controller 50 can control the humidity in the oven 10 by coordinating the operation of the first heating module 315 and the proportional control valve 80 according to the humidity detection signal and the temperature detection signal.

[0129] Please refer to Figure 1 In one embodiment of the present application, the drying device 100 further includes a buffer tank 90 , which is disposed on the air inlet pipe 20 and communicated with the air inlet pipe 20 , and the buffer tank 90 is located downstream of the connecting pipe 33 .

[0130] The cross-sectional area of ​​the buffer tank 90 may be larger than the cross-sectional area of ​​the air inlet pipe 20. The cross-sectional area of ​​the buffer tank 90 may be circular, square, or rectangular, etc., and the present application does not limit the shape of the buffer tank 90.

[0131] In this embodiment, the buffer tank 90 can be provided to buffer the airflow so that the steam flowing out of the connecting pipe 33 and the natural air in the air inlet pipe 20 can be mixed more evenly, thereby improving the uniformity of the humidity of the airflow.

[0132] Please refer to Figure 1In one embodiment of the present application, the drying device 100 further includes a second heating module 101 , which is configured to heat the airflow passing through the air inlet duct 20 , and the second heating module 101 is located downstream of the connecting pipe 33 .

[0133] The second heating module 101 can be used to heat the airflow in the air inlet pipe 20. The second heating module 101 can be an electric heating element, which heats by generating heat through electricity. Of course, the second heating module 101 can also be a furnace, which heats by generating heat through flames. Alternatively, the second heating module 101 can also be a heat exchanger. It can be seen that the present application does not limit the structural type of the second heating module 101. In addition, the second heating module 101 can be arranged on the outside of the air inlet pipe 20, and of course it can also be arranged on the inside of the air inlet pipe 20. The present application does not limit the setting position of the second heating module 101.

[0134] In this embodiment, the mixed airflow of steam and natural air can be heated by the second heating module 101 to reach a preset temperature, thereby achieving drying of the items to be dried in the oven 10 after entering the oven 10 .

[0135] Please refer to Figure 1 In one embodiment of the present application, when the drying device 100 includes a buffer tank 90 and a second heating module 101 , the second heating module 101 is located downstream of the buffer tank 90 .

[0136] Downstream refers to the position that the airflow passes later than the reference object in the flow direction of the airflow. For example, the second heating module 101 is located downstream of the buffer tank 90, and the reference object is the buffer tank 90, which means that the airflow passes through the buffer tank 90 first and then passes through the second heating module 101.

[0137] In this embodiment, the second heating module 101 is arranged downstream of the buffer tank 90, so as to heat the mixed airflow of the steam and the natural air after being evenly mixed, thereby improving the uniformity and accuracy of the temperature of the mixed airflow.

[0138] Please refer to Figure 1 In one embodiment of the present application, the drying device 100 further includes a fan 103 , which is disposed in and connected to the air inlet duct 20 , and the air inlet duct 20 is located between the buffer tank 90 and the second heating module 101 .

[0139] In this embodiment, the fan 103 is arranged between the buffer tank 90 and the second heating module 101, so that the fan 103 can be in contact with the mixed airflow of the uniformly mixed steam and natural air, thereby helping to reduce the impact of the steam in the airflow on the life of the fan 103. At the same time, it can be in contact with the mixed airflow before the mixed airflow is heated, thereby helping to reduce the impact of the airflow on the life of the fan 103 due to excessively high temperature. Of course, the present application is not limited to this, and in other implementations, it is also possible to arrange the fan 103 at other positions of the air inlet pipe 20.

[0140] In one embodiment of the present application, the second heating module 101 is a heat exchanger and is connected to the air inlet pipe 20 .

[0141] The heat exchanger has two flow paths, one of which can be connected to the air inlet pipe 20, and the other can be used for the heating medium to flow through, thereby achieving heat exchange and heating of the airflow entering the air inlet pipe 20 through the heating medium. The heating medium can be heated water or oil.

[0142] In this embodiment, the second heating module 101 is configured as a heat exchanger, which can have a larger heat exchange area, thereby facilitating the heating effect of the airflow in the air inlet pipe 20. Of course, in other embodiments, the second heating module 101 can also be an electric heating element and be disposed outside the air inlet pipe 20, so as to simplify the number of parts of the drying device 100.

[0145] Please refer to Figure 2 In one embodiment of the present application, the drying device 100 also includes a fan 103, which is disposed in the air inlet duct 20 and connected to the air inlet duct 20. The fan 103 is located downstream of the connecting pipe 33, and the end of the return air duct 70 away from the return air port 131 is connected to the fan 103.

[0146] In this embodiment, the fan 103 is provided to provide power so as to drive the airflow from the air inlet pipe 20 into the oven 10. Furthermore, the fan 103 is provided downstream of the connecting pipe 33 and connected to the return air pipe 70, so that the natural air entering from the air inlet pipe 20, the steam in the connecting pipe 33 and the return air flow in the return air pipe 70 can be driven by the fan 103 at the same time, so as to simplify the number of parts of the drying device 100.

[0147] Please refer to Figure 2 In one embodiment of the present application, the oven 10 is extended along a first direction, and the air inlet 121 and the air return port 131 are respectively disposed at two ends of the oven 10 in the first direction.

[0148] The first direction may be the length direction of the oven 10 .

[0149] In this embodiment, the air inlet 121 and the air return port 131 are respectively arranged at the two ends of the length direction of the oven 10, so that the drying airflow can have a relatively long flow path in the oven 10, which is beneficial to extend the drying action time of the drying airflow and improve the utilization effect of the drying airflow.

[0150] Please refer to Figure 2 In one embodiment of the present application, the oven 10 has a first side 15 and a second side 16 opposite to each other in a second direction intersecting the first direction, and the air inlet 121 and the air return port 131 are respectively disposed on the first side 15 and the second side 16 .

[0151] The second direction may be the up-down direction of the oven 10. At this time, the first side 15 may be the upper side of the oven 10, and the second side 16 may be the lower side of the oven 10, or vice versa.

[0152] In this embodiment, the air inlet 121 and the air return port 131 are further arranged on opposite sides of the oven 10, which can further extend the flow path of the drying airflow in the oven 10 so that the drying airflow can fully dry the items to be dried.

[0153] Please refer to Figure 2 In one embodiment of the present application, the oven 10 is further provided with a dehumidification port 141, which is connected to the drying chamber 111. The dehumidification port 141 and the return air port 131 are located at the same end of the oven 10 and are respectively located on opposite sides or adjacent sides of the oven 10.

[0154] The dehumidification port 141 can be used to connect the drying chamber 111 with the outside. Among them, the oven 10 may include a dehumidification cylinder 14 protruding from the outside of the main box 11, and the dehumidification cylinder 14 is connected to the main box 11. At this time, the dehumidification port 141 can be enclosed by the dehumidification cylinder 14. In this way, the connection position and the dehumidification pipe can be conveniently connected through the dehumidification cylinder 14, which is conducive to improving the convenience of connection between the dehumidification pipe and the oven 10. Further, in the wind direction of the dehumidification port 141, the dehumidification port 141 can be further set to a constricted shape so as to control the wind size of the dehumidification cylinder 14. Of course, in other embodiments, when the oven 10 only includes the main box 11. At this time, an opening can be directly opened on the main box 11 to form the dehumidification port 141. In addition, the shape of the dehumidification port 141 can be any shape such as round, square or rectangular.

[0155] In this embodiment, a dehumidification port 141 is further provided on the oven 10 to facilitate the discharge of moisture from the dried items, so as to better control the humidity in the oven 10. The dehumidification port 141 and the return air port 131 are further located at the same end of the oven 10, and are located on opposite sides or adjacent sides of the oven 10, so that they can be at a greater distance from the air inlet 121, reducing the possibility that the drying airflow entering the air inlet 121 directly flows out from the dehumidification port 141.
