Description

Technical Field

[0001] This utility model belongs to the field of graphite anode material recycling technology, and in particular relates to a graphite anode material recycling device. Background Technology

[0002] The recycling of lithium batteries is receiving increasing attention. Currently, lithium batteries mostly use lithium cobalt oxide for the positive electrode and carbon materials such as graphite for the negative electrode.

[0003] Utility model patent CN222586871U discloses a graphite anode material recycling device for lithium batteries, including a collection box with a filter plate slidably mounted on it. Multiple grooves are formed on the inner wall of the collection box, each groove containing a reset device, the output of which is connected to the bottom of the filter plate. Two first slots are symmetrically formed on the inner wall of the collection box, each containing an adsorption device. Two through holes are symmetrically formed on one side of the collection box, with the outputs of the two adsorption devices respectively positioned within the corresponding through holes. A motor is mounted on one side of the collection box via a mounting bracket, the motor's output penetrating one side of the collection box and extending to a cam, which abuts against the bottom of the filter plate. Two protective devices are fixedly mounted on one side of the collection box, each protective device's output abutting against the corresponding adsorption device. This device only screens the anode material, a relatively simple function, and does not separate the metal material from the anode material, which increases the difficulty of subsequent processing and requires heat treatment. Therefore, a graphite anode material recycling device is proposed. Utility Model Content

[0024] The magnetic separation mechanism 4 includes a first gantry frame 41, a first electric push rod 42, a first connecting rod 43, a sliding frame 44, a second electric push rod 45, a second connecting rod 46, a lifting plate 47, and electromagnetic rods 48.

Multiple heaters 55 are installed inside the heating box 54. The heaters 55 are used to heat the negative electrode material.

[0026] The working principle of this utility model is as follows: the first drive motor drives the rotating shaft and cam to rotate. After the cam rotates to contact the screening screen plate, it drives the screening screen plate to rise. After the cam rotates and disengages from the screening screen plate, it is subjected to the action of the spring, and the screening screen plate will descend. The rising and falling of the screening screen plate will create a vibration phenomenon. Then, the negative electrode material is put into the screening box. The screening screen plate will screen the negative electrode material, thereby separating the negative electrode material with larger volume. The qualified negative electrode material will fall into the conveying frame through the screening box.

[0027] After the negative electrode material is screened, the second drive motor drives the lead screw to rotate, and the lead screw drives the conveyor frame to move. The conveyor frame stops when it moves below the first gantry frame. Then, the second electric push rod drives the second connecting rod, the lifting plate, and the electromagnetic rod to descend, so that the electromagnetic rod is inserted into the conveyor frame. Then, the first electric push rod drives the first connecting rod, the sliding frame, the second electric push rod, the second connecting rod, the lifting plate, and the electromagnetic rod to move. During the movement, the electromagnetic rod attracts the metal material in the negative electrode material, thereby preventing the presence of metal material in the negative electrode material. After the metal material is attracted, the second electric push rod drives the second connecting rod, the lifting plate, and the electromagnetic rod to rise to the reset position.

[0028] After the metal material is removed from the negative electrode material, the second drive motor continues to drive the lead screw to rotate, and the lead screw continues to drive the conveyor frame to move. The conveyor frame will stop after it moves to below the second gantry fixing frame. Then, the hydraulic cylinder drives the third connecting rod, heating box and heater to descend, so that the heating box covers the conveyor frame. Then, the heat generated by the heater heats the negative electrode material, thereby heat treating the negative electrode material. High-temperature calcination will remove the binder and residual electrolyte, and at the same time improve the purity of graphite. After the negative electrode material has completed the heat treatment, the hydraulic cylinder drives the third connecting rod, heating box and heater to rise to the reset position.
