Description

TECHNICAL FIELD

[0002] Battery separator is a layer of separator material between the positive and negative electrode of the battery, which is a very critical part of the battery and has a direct impact on the safety and cost of the battery. Its main role is to isolate the positive and negative electrodes and prevent the electrons in the battery from freely passing through, allowing the ions in the electrolyte to pass freely between the positive and negative electrodes.

[0003] In the recycling process of waste power batteries, due to the recyclable nature of the separator, in order to save costs, the separator will be recycled and sorted. The traditional sorting method is to use a vibrating screen to separate the positive and negative electrodes and the separator after the battery is crushed. This screening method has the problems of incomplete separation and low separation efficiency, and has certain disadvantages. Therefore, we propose a battery separator sorting device.

[0020] Reference Figures 1-3A battery separator sorting device includes a frame 1. A stirring mechanism 2 and a separating mechanism 5 are respectively installed at both ends of the top of the frame 1. A first feeding pipe 3 is installed at the bottom of the stirring mechanism 2.

The feeding screw 26 is inserted into the interior of the fixing pipe 23 and rotatably connected to it. The feeding screw 26 is also inserted into the interior of the first feeding pipe 3 and rotatably connected to it. A connecting pipe 7 is installed on the side of the storage hopper 21. The cover plate 4 is hinged to one end of the top of the storage hopper 21. Ventilation holes are provided on the surface of the cover plate 4. The separating mechanism 5... A second feeding pipe 6 is installed at the bottom. A connecting pipe 7 is installed between the side of the stirring mechanism 2 and the separation mechanism 5.

An air outlet pipe 52 is installed on the top of the separation bucket 51. A fan 54 is installed inside the air outlet pipe 53. The air inlet pipe 7 is inserted into the interior of the separation bucket 51 along the tangential direction. The second feeding pipe 6 is installed directly below the separation bucket 51. The connecting pipe 7 is inserted into the interior of the air inlet pipe 52. By setting up a stirring mechanism in conjunction with the separation mechanism, the broken battery fragments are stirred by the stirring mechanism, causing the diaphragm to separate from the battery fragments. Then, the separation mechanism draws in air containing the diaphragm for centrifugal separation in the separation bucket. The diaphragm fragments are discharged through the second feeding pipe. After separation, the battery fragments are fed out using a feeding screw in conjunction with the first feeding pipe. The separation is very thorough and highly efficient.

[0021] In use, the device is connected to a power source. The cover plate 4 is opened to allow the broken battery fragments to be fed into the storage hopper 21.

External air enters the storage hopper 21 through the vent holes on the cover plate 4. The motor 24 is started in reverse. The output shaft of the motor 24 drives the connecting shaft 25 to rotate. The connecting shaft 25 drives the feeding screw 26, which rotates in the opposite direction. The feeding screw 26 cooperates to... The battery fragments at the bottom are tumbled to the top. Due to their small mass, the separator fragments in the battery fragments are easily carried by the airflow through the connecting pipe 7 and the air inlet pipe 52 into the separation hopper 51. The airflow enters at the tangential direction of the separation hopper 51. The airflow moves in a spiral motion in the separation hopper 51. The gas is discharged from the air outlet pipe 53. The separator fragments fall to the bottom of the separation hopper 51 and are discharged from the second discharge pipe 6. After the separator fragments are discharged, the motor 24 is started in the forward direction. The output shaft of the motor 24 drives the feeding screw 26 to rotate in the forward direction through the connecting shaft 25. The feeding screw 26, together with the first discharge pipe 3 and the second discharge pipe 6, discharges the remaining battery fragments.
