The beneficial effects of the present invention are as follows: First, the recycling device of the present invention generates a lot of waste during the NdFeB processing process, and these wastes are recycled and reprocessed to prevent resource waste. First, the NdFeB is recycled through the recycling part. The waste generated in the boron processing process is recycled and stored in a centralized manner. When the storage volume reaches a certain upper limit, it will be reprocessed and reused to reduce the reuse of processing equipment to reuse waste materials and improve processing efficiency. At the same time, storage in the recycling department can also reduce placement In the open environment, there is no protective measure. Long-term storage will cause the NdFeB to oxidize with the air, which will affect the processing effect. Therefore, the recycling department is required to store the waste to minimize contact with the air, thereby improving the reprocessing efficiency. Secondly, when waste materials are stored in the recovery part using the air conditioning device and the inflator, the recovery part is filled with inert gas through the inflator to prevent the NdFeB waste from oxidizing with the air in the recovery part. By working in the inflator When the air conditioning device is turned on, when the recovery part is filled with inert gas, the inert gas is heavier than air and will be under the recovery part. At the same time, the inflator is inflated under the recovery part. This will make the inert gas fill the bottom first and slow down Slowly expand outwards. When the inert gas is filled in, part of the air will flow out with the air conditioning device. After the inert gas is filled in the recovery part, the air conditioning device will be closed to prevent air from proceeding. This ensures that the neodymium Before iron-boron waste is reprocessed and used, the waste will not be oxidized with air, which can also reduce the processing workload during repeated processing of waste and speed up the work progress. Thirdly, a circulation device is installed in the recovery part. The circulation device can reduce the leakage of inert gas and reduce the waste of resources when the waste is taken out. The circulation device and the recovery part are combined to install with extra space between them, and the inflator is inflated The surplus space will also be filled with inert gas, and the inert gas in this surplus space can keep the concentration of inert gas in the recovery part in a stable range, and at the same time, the inner shell of the circulation device can circulate the gas when the waste is discharged. , The through holes on the outer peripheral surface of the inner shell and the recycling channel of the recovery part and the excess space carry out gas circulation backflow. When the waste is discharged, the inflator is inflated and the air flow generated during inflation will push the gas from the circulation channel to the excess space. There is already gas in the surplus space. At this time, the gas in the surplus space will re-enter the recovery part through the circulation hole of the inner shell. This forms a cycle. When the waste is discharged, the gas has been kept circulating, which will reduce the gas output from the waste. The material outlet flows out, which can reduce a large amount of gas loss in the recycling section when the waste is discharged, and a large amount of new gas must be filled after the new waste enters after the discharge is completed, resulting in a waste of resources. Fourth, the use of a mobile device can move the device after the waste recovery is completed, which improves the ease of use of the recovery device. At the same time, the turning device installed inside the recycling department can discharge waste materials. Since the waste materials are diverse, there may be connections between the waste materials, resulting in the failure to quickly come out during discharge. At this time, the turning device is used inside the recycling department. Rotate to break up the waste and improve the discharge efficiency.
