The upper surface of the bracket is fixedly connected with the right side of the upper surface of the sealed upper cover 1. The two exhaust pipes 6 are fixedly connected to the upper surface of the bracket.
[0030] As shown in Figure 2 In this embodiment, a plurality of glass door plates 9 are installed on the front and rear sides of the sealed upper cover 1. The glass door plates 9 are transparent, and the internal operation and water mist condition of the equipment can be observed while the equipment is sealed.
[0031] As shown in Figures 1-6As shown: in this embodiment, the recovery infiltration assembly 10 comprises a chassis 11, a flexible conveying belt 12 and an infiltration machine 13 mounted on the chassis 11. Because the battery pole piece has poor mechanical properties, the flexible conveying belt 12 is selected as the flexible conveying belt 12 to avoid damage to the battery pole piece and affect the subsequent recovery. The flexible conveying belt 12 comprises an upper grid belt 121 and a lower grid belt 122. The top left side of the infiltration machine 13 is driven by a first drive assembly 131 to drive an upper feed drive roller 132 and a lower feed drive roller 133. The first drive assembly 131 can include two motors that drive the upper feed drive roller 132 and the lower feed drive roller 133, respectively. A motor guard is installed on the outside of the first drive assembly 131 to prevent water vapor from overflowing during the heating and infiltration process, which can cause motor corrosion and affect the normal operation and safety of the motor. The top right side of the infiltration machine 13 is driven by a second drive assembly 134 to drive an upper discharge drive roller 135 and a lower discharge drive roller 136. The second drive assembly 134 can include two motors that drive the upper discharge drive roller 135 and the lower discharge drive roller 136, respectively. The inside of the infiltration machine 13 is rotatably connected to a plurality of driven rollers 137 through bearings. The upper grid belt 121 is wound around the outer surfaces of the upper feed drive roller 132, the upper discharge drive roller 135 and the plurality of driven rollers 137. The lower grid belt 122 is wound around the outer surfaces of the lower feed drive roller 133, the lower discharge drive roller 136 and the plurality of driven rollers 137. The upper feed drive roller 132 is located to the right of the lower feed drive roller 133 and forms a feed section.

The feed port 3 of the sealing upper cover 1 is located at the feed section of the recovery infiltration assembly 10. The discharge port 4 of the sealing upper cover 1 is located at the discharge section of the recovery infiltration assembly 10.
[0032] Because the battery pole piece has a sandwich structure, film / aluminum foil / film, and needs to be infiltrated on both sides, the lower grid belt 122 protrudes and is the feeding area of the recovered battery pole piece. The upper grid belt 121 ensures that the upper layer of the battery pole piece is infiltrated. The sealing upper cover 1 can seal the upper side of the infiltration machine 13, preventing water vapor from overflowing and ensuring the cleanliness of the workshop environment.

[0037] As shown in Figure 3 and Figure 4 : In this embodiment, the right side of the soaking machine 13 is provided with a collection assembly 17, and the right side of the collection assembly 17 gradually inclines downward. By arranging the collection assembly 17, the battery pole pieces that fail to flow into the next work section are transported by the lower grid belt 122 and fall into the collection assembly 17, thereby facilitating recycling.
[0038] As shown in Figure 4 : In this embodiment, the bottom of the soaking machine 13 is provided with a wastewater outlet 18, a heat exchange pure water inlet 19, a normal temperature pure water inlet 20 and a heat exchange pure water outlet 21.

The temperature of the added pure water is composed of heat exchange pure water and normal temperature pure water. The temperature of the water in the soaking machine 13 is detected by a temperature sensor. The temperature fluctuation can be reflected by the pure water in and out of the heat exchange pure water outlet 21. By designing the bottom of the soaking machine 13 as a slope, it is convenient to clean and replace the pure water in the soaking machine 13, and the accumulation phenomenon is avoided.
[0040] As shown in Figure 4 : In this embodiment, the front and rear sides of the chassis 11 are provided with a plurality of sealing bottom plates 22, and the lower surface edges of the chassis 11 are provided with a plurality of supporting legs 23.
[0041] The sealing bottom plates 22 protect the electronic components inside the chassis 11, prevent the overflow of water vapor from causing equipment corrosion, and the electronic components inside the chassis 11 control the recycling soaking assembly 10 and the dehumidification device.
