Description

Technical Field

[0001] This utility model relates to the field of lithium battery recycling, and in particular to a feeding machine for lithium battery recycling. Background Technology

[0002] Lithium-ion batteries are a type of battery that uses lithium metal or lithium alloys as positive and negative electrode materials and a non-aqueous electrolyte solution. A traditional lithium-ion battery consists of five main parts: positive electrode material, negative electrode material, electrolyte, diaphragm, and casing. Because lithium-ion batteries contain many harmful substances that can pollute the environment, they need to be recycled after degradation. The recycling process begins by shredding large parts such as the battery casing and metal terminals into smaller fragments, which are then fed into a rotary drum screen for further screening.

[0003] In production, recycled lithium battery materials are generally placed in a recycling hopper. The materials in the recycling hopper are manually shoveled onto the feeding end of a belt and then conveyed to the drum screen via the belt. Traditional belt conveyors mainly use a conveyor belt for transportation. Generally, belt conveyor devices are open, and there is a certain distance between the belt and the feed inlet of the drum screen. This causes dust and membrane fragments to be generated during the feeding process, polluting the surrounding environment. Therefore, technical improvements are needed. Utility Model Content

[0007] In a preferred embodiment of this utility model, the drive motor is mounted above the motor bracket, and pulleys are mounted on both the drive motor and the transmission roller on the same side as the drive motor. The drive motor is connected to the transmission roller by a belt.

[0008] As a preferred embodiment of this utility model, a plurality of the carrying idlers are evenly distributed along the length of the belt frame. The carrying idlers are fixed to the top of the belt frame by bolts. The carrying idlers are composed of two sets of symmetrically inclined circular rollers, which form a V-shape.

[0023] like Figure 1-4 As shown, this utility model provides a feeding machine for lithium battery recycling, including a frame 1, a feeding hopper 2, a conveyor belt 3, a belt frame 4, and a drive motor 5;

[0024] The feed hopper 2 is welded to the top of the frame 1, the conveyor belt 3 is located below the frame 1, and a motor bracket 6 is provided on one side of the belt frame 4; drive rollers 7 are installed at the left and right ends of the belt frame 4, and several carrying rollers 8 are installed on the belt frame 4 between the two drive rollers 7; a discharge hopper 9 is provided at the end of the conveyor belt 3, and the discharge hopper 9 is fixed to the end of the belt frame 4 by bolts. The conveyor belt 3 is wound around the drive rollers 7 and the carrying rollers 8; a feed cover 10 is also hinged to the upper end of the feed hopper 2, and an exhaust pipe 11 for recycling the diaphragm and dust is welded and fixed to the top of the feed cover 10. Preferably, the bottom of the feed hopper 2 is provided with a valve that can adjust the discharge rate.

[0025] The method of using this utility model is as follows:

[0026] 1. Rotate upward to open the feed cover 10, so that the feed cover 10 and the feed hopper 2 form a certain acute angle of opening. Use the overhead crane to pour the lithium battery mixture in the recycling hopper into the feed hopper 2, and then rotate downward to close the feed cover 10.

[0027] 2. Turn on the exhaust fan (not shown) connected to the exhaust pipe 11 to suck away the diaphragm and dust in the mixture, and open the valve at the bottom of the feed hopper 2 to let the mixture fall onto the conveyor belt 3;

[0028] 3. Turn on the drive motor 5 to output the mixture from the feed hopper 9 to the inlet of the equipment for the next process.

[0029] Furthermore, the drive motor 5 is bolted to the motor bracket 6. Both the drive motor 5 and the transmission roller 7 on the same side as the drive motor 5 are equipped with pulleys. The drive motor 5 is connected to the transmission roller 7 by a belt to drive the conveyor belt 3.

[0030] For further details, please refer to Figure 1 Several carrying idlers 8 are evenly distributed along the length of the belt frame 4. The roller shaft of the carrying idler 8 is rotatably connected to the idler fixing frame. The idler fixing frame is fixed above the belt frame 4 by bolts. The carrying idler 8 is composed of two sets of symmetrically inclined circular rollers. The two sets of circular rollers form a V shape. The carrying idler 8 is used to carry the conveyor belt 3.

[0031] In this embodiment, the conveyor belt 3 is a groove shape with a low middle and high sides. When the recycled material falls from the feed hopper 2, it falls into the groove on the conveyor belt 3 under the action of gravity, and then is conveyed to the feed hopper 9 by the conveyor belt.

[0032] Furthermore, the feed hopper 2 is welded to the top of the frame 1. A hinge shaft is provided on one side of the feed hopper 2, and a hinge hole is provided on one side of the feed cover 10. The feed hopper 2 and the feed cover 10 are hinged together, and the feed cover 10 and the feed hopper 2 form a certain acute angle.

[0033] In this embodiment, the feed cover 10 can rotate along the feed hopper 2. The lithium battery recycling mixture to be separated can be added to the feed hopper 2 by the overhead crane in the workshop. After the material is added, the feed cover 10 can be closed. The feed cover 10 and the feed hopper 2 form a sealed space to prevent the diaphragm and dust from overflowing and polluting the workshop environment.

[0034] Furthermore, horizontal sliding rods 12 are connected to the middle of both sides of the feed hopper 2. Sliding grooves are provided on both sides of the feed hopper 2. The horizontal sliding rods 12 are slidably connected to the feed hopper 2 and can slide horizontally. A connecting rod 13 is provided between the feed hopper 2 and the feed cover 10.

[0035] In this embodiment, when the feed cover 10 rotates along the hinge, the horizontal sliding rod 12 slides horizontally synchronously in the sliding grooves on both sides of the feed hopper 2, and the connecting rod 13 rotates at a certain angle following the horizontal sliding rod 12, thereby realizing the closure of the feed cover 10 and the feed hopper 2, forming a sealed space, which makes it easy for the exhaust pipe 11 to extract light impurities such as diaphragms in the feed hopper 2.

[0036] Furthermore, the lower end of the exhaust pipe 11 is connected to the feed hopper 2. Preferably, the exhaust pipe 11 is welded to the top of the feed hopper 2, and the other end of the exhaust pipe 11 is connected to an exhaust fan for extracting the separator and dust in the lithium battery recycling material. After subsequent filtration processes, the lithium battery separator can be recycled and reused.

[0037] This utility model is a feeding machine for lithium battery recycling, which realizes the separation and recycling of lithium battery separators, while effectively improving the working environment. The feeding personnel are away from the feeding hopper, reducing the amount of dust inhaled by the personnel, protecting their health, and greatly improving work efficiency.
