The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0027] like Figures 1 to 5 As shown, a drying oven humidification structure includes a drying oven 1 and a humidification structure 2. The drying oven 1 is provided with a drying chamber 11. The drying chamber 11 includes a plurality of arranged upper air nozzles 12 and lower air nozzles. The humidification structure 2 includes

[0028] A humidifying nozzle 21, wherein the humidifying nozzle 21 is located at the side of the upper air nozzle 12 and / or the lower air nozzle;

[0029] A fan 22, the air outlet of the fan 22 is connected to the humidifying nozzle 21 via an air outlet duct 24, and the air inlet of the fan 22 is connected to the exhaust pipe 13 of the oven 1 via an air inlet duct 25;

[0030] The steam pipe 23 has one end connected to high temperature steam and the other end connected to the fan 22 through a pipe.

[0031] Taking advantage of the high humidity of the exhaust pipe 13 of the oven 1, a steam pipe 23 is introduced to the fan 22 at the same time, and the wind at the exhaust port is introduced into the upper nozzle 12 and / or the side of the lower nozzle in the oven 1 through the fan 22, so as to increase the humidity of the air near the electrode, slow down the drying speed, thereby reducing the cracking of the electrode and improving the drying yield of the electrode.

[0032] At this time, the steam pipe 23 is used to introduce steam. In this embodiment, the steam pipe 23 includes a first manual valve 231, a Y-type filter 232, a steel shell filter 233, a pressure gauge 234, and a second manual valve 235 which are connected in sequence through pipelines. The first manual valve 231 is connected to a high-temperature steam source through a pipeline, and the second manual valve 235 is connected to the fan 22 through a pipeline. The first manual valve 231 and the second manual valve 235 are used to control the connection or disconnection of the steam pipe 23. The Y-type filter 232 is used to filter impurities in the steam pipe 23. The steel shell filter 233 adopts a filtration accuracy of 500 meshes to further filter impurities in the high-temperature steam to prevent impurities from entering the oven 1 and causing pollution during the drying process of the electrode. The pressure gauge 234 is used to monitor the pressure in the steam pipe 23, so as to realize the transmission of high-temperature steam from the steam source to the fan 22 position.

[0033] When the steam pipe 23 is used to increase the humidity, in order to prevent the high-temperature steam in the steam pipe 23 from being directly transmitted to the fan 22 and affecting the normal operation of the fan 22, in this embodiment, the second manual valve 235 of the steam pipe 23 is connected to the air inlet pipe 25 of the fan 22 through a pipe, so as to prevent the high-temperature steam from directly entering the fan 22, thereby extending the service life of the fan 22.

[0034] Since the humidity in the oven 1 is controlled by the wind with high humidity at the exhaust pipe 13, it is also necessary to control the amount of air entering the interior of the oven 1 from the exhaust pipe 13. Therefore, in this embodiment, an electric valve 251 is provided between the air inlet duct 25 connecting the exhaust pipe 13 and the steam pipe 23. The electric valve 251 controls the amount of air entering the fan 22 from the exhaust pipe 13, thereby controlling the humidity in the oven 1.

[0035] Of course, at this time, it is also necessary to control the amount of steam entering the fan 22 through the steam pipe 23 to achieve control of the humidity in the oven 1. Specifically, the steam pipe 23 at this time is provided with a regulating valve for controlling the amount of high-temperature steam entering the fan 22 to achieve control of the humidity in the oven 1.

[0036] Furthermore, in order to detect the humidity in the oven 1, in the present embodiment, the oven 1 is provided with a first humidity sensor for detecting the humidity in the oven 1, and the air outlet duct 24 is provided with a second humidity sensor for detecting the humidity in the air outlet duct 24. By detecting the humidity at the position of the air outlet duct 24 and the humidity in the oven 1, the humidity in the oven 1 can be adjusted, thereby realizing automatic adjustment of the humidity at the position of the oven 1 and ensuring that the humidity in the oven 1 is maintained within the required range.

[0037] The air outlet duct 24 is used to introduce air with a certain humidity at the position of the fan 22 into the internal position of the oven 1. Therefore, in this embodiment, the air outlet duct 24 includes a main duct 241, the main duct 241 is connected to the fan 22, and the main duct 241 is provided with a plurality of branch ducts 242 connected to each other. The branch ducts 242 are connected to a transverse duct 243, and the humidifying nozzle 21 is connected to the transverse duct 243. At this time, the connection between the main pipe 241 and the fan 22 is set at the upper side of the fan 22, which can prevent the liquid water accumulated in the fan 22 from being blown out from the air outlet of the fan 22. At the same time, multiple branch pipes 242 are connected through a main pipe 241, and the branch pipes 242 are connected to the corresponding transverse pipes 243, so as to realize the connection between the main pipe 241 and the humidifier nozzle 21. At this time, a valve can be designed on a separate branch pipe 242 to control the channel of the branch pipe 242, and then the opening of the transverse pipe 243 and the humidifier nozzle 21 corresponding to the corresponding branch pipe 242 can be controlled, so as to control the humidity of the corresponding upper nozzle 12 position. In this way, the humidity of the upper nozzle 12 position accessories at a specific position can be adjusted separately, so as to more accurately adjust the humidity in the oven 1.

[0038] Furthermore, a plurality of humidifying nozzles 21 are connected via a transverse pipe 243 , and the humidifying nozzles 21 are distributed at the side positions of the upper air nozzle 12 and / or the lower air nozzle along the direction of the drying transverse pipe 243 , so as to achieve the purpose of controlling multiple humidifying nozzles 21 by one branch pipe 242 .

[0039] The humidifier nozzle 21 is arranged at the side of the upper air nozzle 12. Therefore, in order to better fix the humidifier nozzle 21 and the corresponding transverse pipe 243, a fixing bracket 26 is provided on the outside of the transverse pipe 243, and the transverse pipe 243 is fixed to the side of the upper air nozzle 12 and / or the lower air nozzle through the fixing bracket 26.

[0040] In order to increase the contact area between the inside of the humidification nozzle 21 pipe and the outside, in the present embodiment, the outer side of the humidification nozzle 21 is inclined. At the same time, in order to prevent the humidification nozzle 21 from affecting the normal drying process of the electrode, the outer side of the humidification nozzle 21 is not higher than the outer side of the upper air nozzle 12 and / or the lower air nozzle to prevent the humidification nozzle 21 from contacting the electrode.

[0041] Since air with a certain humidity is introduced into the oven 1, during the process of introducing air with a certain humidity, in order to prevent moisture in the air from condensing into water and then being blown out from the humidifying nozzle 21, in this embodiment, a first drainage hole is provided at the bottom of the fan 22, and a second drainage hole is provided at the main pipeline 241. Multiple drainage holes are provided to discharge condensed water to prevent water droplets from being sprayed directly from the humidifying nozzle 21 onto the electrode, thereby affecting the drying quality of the electrode.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
