Figure 5 、 Figure 8As shown, the end of the support 1022 away from the supporting end is the connecting end, and a through hole 1024 and a threaded hole 1025 are respectively provided on both sides of the connecting end. A fastener 1023 is passed through each through hole 1024, and there is no internal thread in the through hole 1024. After the fastener 1023 passes through the through hole 1024, it is threadedly connected to the first air nozzle accommodating cavity 107. An adjusting rod is passed through the threaded hole 1025, and the adjusting rod is in contact with the first air nozzle accommodating cavity 107, that is, the adjusting rod is located at the bottom of the support 1022. Specifically, a threaded hole is provided at the position of the first nozzle accommodating chamber corresponding to the through hole 1024, and the fastener 1023 is a fastening bolt, which passes through the through hole 1024 and is threadedly connected to the threaded hole of the first nozzle accommodating chamber 107; the adjusting rod is an adjusting bolt, which passes through the threaded hole 1025 and abuts against the top of the first nozzle accommodating chamber 107. When it is necessary to adjust the gap between the support 1022 and the first nozzle accommodating chamber 107, the adjusting bolt is rotated, and the adjusting bolt drives the support 1022 closer to or away from the first nozzle accommodating chamber 107, thereby realizing the change of the gap between the support 1022 and the first nozzle accommodating chamber 107. After the height adjustment is completed, the thread of the first nozzle accommodating chamber 107 is connected by the fastening bolt to fix the support 1022.

[0046] To blow air to the electrode 9 to be dried, Figure 3 、 Figure 4 and Figure 5 As shown, the first nozzle accommodating chamber 107 and the second nozzle accommodating chamber 108 are respectively provided with an air outlet nozzle 1072 arranged toward the electrode 9 to be dried. To control the air output of the air outlet nozzle, a first nozzle valve 1071 is provided in the first nozzle accommodating chamber 107 and a second nozzle valve 1081 is provided in the second nozzle accommodating chamber 108. The first nozzle valve 1071 and the second nozzle valve 1081 control the air output volume and wind speed of the air outlet nozzle 1072.

[0047] To achieve exhaust, the drying area also includes two exhaust chambers, one exhaust chamber is located on the side of the first nozzle accommodating chamber 107 away from the conveying channel, and the other exhaust chamber is located on the side of the second nozzle accommodating chamber 108 away from the conveying channel. The exhaust chambers are connected to the conveying channel through the connecting pipe 1013. Figure 3 、 Figure 6 As shown, the exhaust cavity located above the second nozzle accommodating cavity 108 is provided with an exhaust duct 105, and an exhaust air valve 1051 is provided in the exhaust duct 105, which controls the opening and closing of the exhaust duct 105. Figure 5 、 Figure 7As shown, the top and bottom of the first air nozzle accommodating chamber 107 are respectively provided with a plurality of return air outlets 1012, and the return air outlet 1012 at the top of the first air nozzle accommodating chamber 107 is connected to the return air outlet 1012 at the bottom through a connecting pipe 1013; the top and bottom of the second air nozzle accommodating chamber 108 are respectively provided with a plurality of return air outlets 1012, and the return air outlet 1012 at the top of the second air nozzle accommodating chamber 108 is connected to the return air outlet 1012 at the bottom through a connecting pipe 1013, so that the air in the conveying channel enters the exhaust chamber through the return air outlet 1012.

[0048] like Figure 5 、 Figure 7 As shown, the heating zone includes a return air accommodating chamber 109, a fresh air accommodating chamber 1010 and a hot air accommodating chamber 1011 which are connected in sequence. The return air accommodating chamber 109 is connected to the exhaust chamber, and the hot air accommodating chamber 1011 is connected to the first air nozzle accommodating chamber 107 and the second air nozzle accommodating chamber 108 respectively. Figure 3 、 Figure 5 、 Figure 6 and Figure 7 As shown, a fresh air inlet 104 is provided at the top of the fresh air receiving chamber 1010, and a centrifugal fan 7 is provided below the fresh air inlet 104; a heating pack 8 and a filter are provided in the hot air receiving chamber 1011, the heating pack 8 is used to heat the air flowing into the fresh air receiving chamber 1010, and the filter is used to filter the heated hot air. Figure 3 、 Figure 6 As shown, an explosion-proof opening 103 and a temperature sensor 106 are provided on the top of the exhaust cavity above the second air nozzle accommodating cavity 108, wherein the temperature sensor 106 is used to sense the temperature in the exhaust cavity.

[0049] like Figure 3 、 Figure 7 As shown, a door body 6 is further provided on the side wall of the box body 1. One side of the door body 601 is rotatably connected to the box body 1 through a hinge, and a handle is provided on the other side of the door body 6 to open or close the door body 6.

[0050] An oven system, such as Figure 1 、 Figure 2 、 Figure 3 As shown, it includes three integrated ovens connected end to end, and a base 2 is arranged under each integrated oven. Figure 1 、 Figure 2 As shown, it also includes an air duct 3, the bottom of which is connected to the exhaust pipe 105 of each integrated oven box 1, and an exhaust valve 1051 is provided on the exhaust pipe 105. Figure 1 、 Figure 2 As shown, a main fan 4 is provided on the side of the air duct 3, and the main fan 4 is connected to the air duct 3. Figure 1 As shown, a bracket 5 is provided at the main fan 4.

[0051] In order to realize automatic control, a controller is also included, which is respectively communicated with the heating bag 8, the telescopic rod 602, the centrifugal fan 7, the pressure sensor, the fresh air valve 1041, the first air nozzle valve 1071, the second air nozzle valve 1081, the exhaust air valve 1051, etc.

[0052] During the specific implementation process, the handle is rotated to open the door body 6. The on-site personnel first adjust the overall height of the roller shaft 1021 to separate the fastener 1023 from the first nozzle accommodating chamber 107. The adjusting rod is rotated to adjust the gap between the support 1022 and the first nozzle accommodating chamber 107 to change the height of the roller shaft 1021 so that the height of the central axis of all the roller shafts 1021 is equal. After the height of the roller shaft 1021 is adjusted, the handle is rotated to close the door body 6. The electrode to be dried moves along the conveying channel in the oven body 1. The external air enters the fresh air accommodating chamber 1010 through the fresh air inlet 104. The controller starts the centrifugal fan 7. The fresh air valve 1041 controls the wind speed and flow rate from the fresh air accommodating chamber 1010 to the hot air accommodating chamber 1011. The heating bag 8 in the hot air accommodating chamber 1011 heats the incoming air, and the filter filters the heated air. After the temperature reaches the preset value, the air is discharged into the first air nozzle accommodating chamber 107 and the second air nozzle accommodating chamber 108, and is blown out toward the electrode 9 to be dried by the air outlet 1072 of the first air nozzle accommodating chamber 107 and the second air nozzle accommodating chamber 108. Since the size of the inlet and outlet 101 is slightly larger than the electrode 9 to be dried, most of the air in the box 1 enters the return air accommodating chamber 109 through the return air port 1012 and the connecting pipe 1013, and then enters the fresh air accommodating chamber 1010 from the return air accommodating chamber 109 to complete the air circulation. During the whole process, the centrifugal fan 7 provides the power for the air flow, so that the air circulates under a certain pressure.

[0053] During the use of the oven system, when it is necessary to introduce air into a certain integrated oven body 1, the fresh air valve 1041 is opened, and the centrifugal fan 7 provides power, and the air outside the body 1 enters the fresh air receiving chamber 1010 through the fresh air port 104; when a certain integrated oven body 1 needs to be exhausted, the main fan 4 is started, the exhaust valve 1051 is opened, and the air in the return air receiving chamber 109 enters the air duct 3 through the exhaust duct 105 for exhaust.

[0054] The integrated oven and oven system provided by the present invention have the following advantages: (1) the height of the roller shaft 1021 can be adjusted at any time on site without completely disassembling the oven housing 1; (2) since the size of the inlet and outlet 101 is slightly larger than the size of the electrode 9 to be dried, most of the wind in the conveying channel is circulated in the same housing 1, and the circulating wind maintains a certain temperature, thereby reducing the power consumption of the heating pack 8 and lowering the production cost; (3) the centrifugal fan 7 is placed in the fresh air receiving chamber 1010 and the heating pack 8 is placed in the hot air receiving chamber 1011, realizing the integrated setting of the device and the housing 1 and reducing the space occupied by the integrated oven.

[0055] As an alternative embodiment, the number of integrated ovens in the oven system may be 2, 4, 5 or even more.

[0056] As an alternative embodiment, the adjusting rod may also be provided on the side of the support 1022 , and the adjusting rod slides relative to the side wall of the box body 1 to adjust the height of the roller shaft 1021 .

[0057] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
