[0002] Air separation technology is a physical sorting method based on aerodynamic principles. It separates materials of different densities and shapes by generating directional airflow. In the field of waste lithium battery processing, air separation technology is used to separate lightweight diaphragm materials and other heavier metal or plastic components. This method has the advantages of simple operation, low cost, and no chemical reaction, making it suitable for large-scale industrial applications.
[0003] In practical applications, existing air separation and recycling equipment for waste lithium batteries has some limitations, especially when processing crushed battery components. Due to the complex internal structure of the battery, the positive and negative electrode materials and electrolyte components are prone to agglomeration, which not only leads to uneven material distribution, but also seriously affects the effect of air separation, making it difficult to effectively separate lightweight diaphragm materials. In addition, agglomerated materials may clog air separation equipment, reduce production efficiency, and increase maintenance costs.
[0004] Therefore, there is an urgent need to provide a membrane air separation and recovery device for waste lithium battery processing with a material breaking up function. Utility Model Content

DETAILED DESCRIPTION
[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0020] Example 1: Please refer to Figure 1-Figure 4A membrane air separation and recovery device for waste lithium battery processing includes a shell 1, a feeding channel is provided on the top of the shell 1, for feeding the waste lithium battery components to be processed, an air inlet is provided at the bottom left of the shell 1, and a discharge port is provided at the corresponding position on the right side to ensure that the airflow during the air separation process can effectively push the lightweight membrane to the discharge port, and a dustproof plate 18 is hinged on the discharge port to prevent external dust and other impurities from entering the recovery device when the device is not in use, so as to keep the interior of the device clean. An air guide frame 101 is installed at the air inlet, and below the air inlet A support frame 2 is provided, on which a blower 3 is installed. The air outlet of the blower 3 is connected to one end of an air pipe 4, and the other end of the air pipe 4 is installed with an air separation nozzle 5. The air separation nozzle 5 is located in the air guide frame 101 to ensure that the air flow can accurately act on the material falling from the feed channel. In addition, the air pipe 4 is designed as a soft plastic as a whole, with good flexibility and bending performance. It can bend to a certain extent as the air outlet nozzle moves, supporting the adjustment of the blowing angle. A windproof cloth 19 is provided between the air separation nozzle 5 and the air guide frame 101. To ensure that the air separation nozzle 5 can rotate while preventing air leakage, an arc-shaped guide rail 6 is provided on the front and rear sides of the air inlet, and a guide rod 7 is slidably installed on the arc-shaped guide rail 6. The guide rod 7 is connected to the air separation nozzle 5 and can drive the air separation nozzle 5 to move along the arc-shaped guide rail 6 and change its inclination angle to adapt to different sorting requirements. An electric rolling wheel 8 is installed in the central position of the shell 1. The rolling wheel is mainly used to assist the movement of lightweight materials such as diaphragms. A material receiving cavity is provided just below the feed channel for temporarily storing heavier materials that have not been air-selected. The material receiving cavity It is equipped with a slidable baffle 9, and the operator discharges the waste from the receiving chamber by pulling out the baffle 9. A motor 13 is installed on the rear side of the feed channel of the shell 1. Five parallel-arranged breaking rods 15 are rotatably installed inside the feed channel to break up the clumped materials. One of the breaking rods 15 is connected to the output shaft of the motor 13 as a power input point. A gear 14 is provided on each breaking rod 15, and adjacent gears 14 are engaged with each other to form a continuous transmission chain, so that all the breaking rods 15 can rotate synchronously to effectively break up the incoming materials.
[0021] See also Figure 3 A collecting frame 16 is provided at the bottom of the shell 1 near the electric scroll wheel 8. Its main function is to collect lightweight materials that cannot be carried away by the airflow after air separation. These materials are moved to the collecting frame 16 with the assistance of the electric scroll wheel 8 to facilitate subsequent centralized processing or further recycling. Blocks 17 are provided on both sides of the upper end of the collecting frame 16. A card slot matching the card block 17 is opened at the corresponding position of the shell 1. The card block 17 is inserted into the card slot, which ensures that the collecting frame 16 is firmly fixed in the shell 1 during operation, and the collecting frame 16 can be quickly installed and disassembled.
[0022] When the device is used, first, according to the flow characteristics of different materials and the internal structure of the shell 1, the guide rod 7 on the arc guide rail 6 is pulled to change the blowing angle of the air separation nozzle 5, so that the airflow path is more reasonable, ensuring that the airflow can effectively act on the material to be sorted, thereby improving the accuracy and purity of the sorting. After the device adjustment is completed, the waste lithium battery components that have been preliminarily decomposed are fed into the device through the feeding channel at the top. At the same time, the output shaft of the motor 13 drives the breaking rod 15 connected thereto to rotate. Since the gears 14 on all the breaking rods 15 are engaged with each other to form a continuous transmission chain, the power of the motor 13 is transmitted to each breaking rod 15 through the gear 14 transmission system, so that all the breaking rods 15 rotate synchronously, and as the breaking rods 15 rotate, the breaking rods 15 entering The material in the feed channel exerts mechanical force to break up the existing agglomerated materials into smaller particles or single components, which helps to evenly distribute the material and reduce the falling speed of the material, thereby improving the efficiency and accuracy of subsequent air separation and sorting. When the evenly dispersed material enters the outer shell 1, the blower 3 is started to generate a strong airflow, which is input into the air separation nozzle 5 through the air pipe 4 and released. Since the diaphragm material is relatively light, the strong airflow will separate them from other heavier battery components and push them to the relative discharge port. At the same time, the rotation of the electric rolling wheel 8 assists the movement of lightweight materials such as the diaphragm to ensure that they reach the discharge port smoothly, and those heavier components that cannot be carried away by the airflow fall into the receiving chamber below. The operator controls the discharge of waste material by pulling out the baffle 9.
[0023] Example 2: Based on Example 1, please refer to Figure 3 The air inlet of the shell 1 is slidably provided with a wind shield 10 symmetrically distributed up and down, which is used to adjust the opening size of the air inlet. A guide rod 11 is provided on one side of the air inlet to provide a sliding guide for the wind shield 10. A bidirectional screw 12 is rotatably provided on the other side of the air inlet. The bidirectional screw 12 is threadedly connected to the wind shield 10. Due to the opposite thread design at both ends of the screw, the two wind shields 10 can be driven to move inward or outward synchronously by rotating the bidirectional screw 12.
[0024] According to the actual sorting needs, the size of the air inlet is adjusted to accurately control the air flow and pressure entering the air separation area. The bidirectional screw 12 is rotated clockwise to drive the two wind shields 10 to move inward along the guide rod 11, reducing the air inlet, making the airflow more concentrated, and forming a stronger local airflow, which helps to accurately separate the diaphragm material from the material and ensure the sorting effect. Rotating the bidirectional screw 12 counterclockwise will move the two wind shields 10 outward, increase the air inlet, disperse the airflow, increase its coverage, and allow more materials to be affected by the airflow at the same time, thereby improving the speed and efficiency of sorting.
[0025] The above description is merely an example of the implementation of the present invention and is not intended to limit the present invention. Any equivalent substitutions made within the principles of the present invention shall be included within the scope of protection of the present invention. Any matters not fully described in the present invention are prior art known to those skilled in the art.
