[0049] like Figure 5 、 Figure 6 、 Figure 8 As shown, a door assembly 9 is further provided on the side wall of the oven housing 1. The door assembly 9 includes a telescopic rod 902 and an opening and closing door 901. One side of the opening and closing door 901 is rotatably connected to the oven housing 1 via a hinge. The telescopic rod 902 drives the opening and closing door 901 to open or close. The opening and closing door 901 is driven to move by the telescopic rod 902. Specifically, the telescopic rod 902 is a nitrogen spring rod.

[0050] An oven system comprises three integrated ovens connected in series, such as Figure 1 、 Figure 2 As shown, the three integrated ovens have an inlet 1021 and an outlet 1022 along the conveying channel 102. It should be noted that the size of the inlet 1021 and the outlet 1022 is slightly larger than the electrode to be dried, so that the air in the oven body 1 can be easily recycled. Figure 2 As shown, it also includes a drive assembly 5. A roller 504 is provided in the conveying channel 102 of each oven box 1. The drive assembly 5 includes a drive member 501 provided on the top of the oven box 1. A synchronous wheel 503 is provided on the top of each oven box 1. The synchronous wheel 503 is connected to the drive member 501 through a belt 502. The synchronous wheel 503 of each oven box 1 is connected to the roller 504 through a belt 502, so that the rollers 504 in different oven boxes 1 can move synchronously and at the same speed, ensuring the consistency of the electrodes to be dried in the entire oven system. In order to protect the drive assembly 5, as shown in FIG. Figure 5 、 Figure 7 As shown, the synchronous wheel 503 and the belt 502 on the top of the oven body 1 are placed in the protective cover 101, and a pressure sensor 1013 is also provided in the protective cover 101.

[0051] like Figure 1 、 Figure 3 As shown, it also includes an air duct 3, which is provided with an air inlet duct and an air outlet duct. A fresh air inlet 302 is provided at the top of the air inlet duct, and a fresh air outlet is provided at the bottom of the air inlet duct. The fresh air inlet 302 is connected to the fresh air port 106 of each oven body 1 through a fresh air pipe 304. Each fresh air pipe 304 is provided with a fresh air valve 303. Figure 1 、 Figure 3 As shown, an exhaust fan 4 is also provided on the side of the air duct 3, and the exhaust fan 4 is connected to the air outlet duct, and the entire oven system is placed above the bottom frame 2. Figure 1 、 Figure 2 As shown, the bottom of the air outlet duct is connected to the exhaust port 105 of each oven body 1 through an exhaust pipe 301, and an exhaust valve is provided in each exhaust pipe.

[0052] In order to realize automatic control, a controller is also included, which is respectively communicated with the heating bag 7, telescopic rod 902, centrifugal fan 6, pressure sensor 1013, fresh air valve 303, upper air nozzle valve 1071, lower air nozzle valve 1081, exhaust air valve, etc.

[0053] During the specific implementation process, in an oven box 1, the roller 504 rotates to make the electrode to be dried move along the conveying channel 102, and the external wind enters the fresh air receiving chamber 1010 through the fresh air inlet 106. The controller starts the centrifugal fan 6 located in the fresh air receiving chamber 1010, and the fresh air valve 303 controls the wind from the fresh air receiving chamber 1010 to the hot air receiving chamber 1011. The centrifugal fan 6 is connected to the heating bag 7, and the heating bag 7 heats the wind to a preset temperature and then discharges it into the hot air receiving chamber 1011. The hot air receiving chamber 1011 is heated and discharged to the hot air receiving chamber 1011. After passing through filter 8, the air in intake chamber 1011 flows into upper nozzle accommodating chamber 107 and lower nozzle accommodating chamber 108. Upper nozzle air valve 1071 and lower nozzle air valve 1081 control the amount of air blown from nozzle 109 to the drying electrode. Most of the air in delivery channel 102 flows through the connecting pipe of return air port 103 into exhaust chamber 1012. From exhaust chamber 1012, it flows into outlet 10121 and is discharged into return air accommodating chamber 104. From return air accommodating chamber 104, it enters fresh air accommodating chamber 1010, completing the air circulation. During this process, centrifugal fan 6 provides the power for the air flow, causing the air to move under a certain pressure, achieving circulation.

[0054] During the use of the oven system, when air needs to be supplied to a certain integrated oven, the fresh air valve 303 is opened, and air is introduced from the fresh air inlet 302, powered by the centrifugal fan 6, so that air enters the fresh air receiving chamber 1010 through the fresh air inlet 302 along the air inlet duct; when a certain integrated oven needs to be exhausted, the exhaust valve is opened, powered by the exhaust fan 4, and air is exhausted from the exhaust port 105 of the return air receiving chamber 104 along the air outlet duct into the main air duct 3.

[0055] The integrated oven and oven system provided by the present invention have the following advantages: (1) the air in the oven is circulated. Since the size of the sample inlet 1021 and the sample outlet 1022 is slightly larger than the electrode to be dried, most of the air can be circulated in the same oven body 1. The recycled air will maintain a certain temperature. The oven recovers the waste heat of the hot air, which reduces the power consumption of the heating pack 7 to a certain extent; (2) the centrifugal fan 6 is placed in the fresh air receiving chamber 1010 and the heating pack 7 is placed in the hot air receiving chamber 1011, thereby realizing the integrated setting of the relevant devices and the oven body 1 and reducing the space occupied by the oven body 1; (3) the setting of air intake and exhaust is realized by a main air duct 3, which optimizes the pipeline setting of the entire system; (4) the door assembly 9 is provided to facilitate maintenance of the oven body 1.

[0056] As an alternative embodiment, the number of integrated ovens in the oven system may be 2, 4, 5 or even more.

[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.
