Abstract
Description
Technical Field
[0001] This utility model relates to the field of neodymium iron boron material utilization technology, and in particular to a crushing device for recycling and reusing waste from sintered neodymium iron boron production. Background Technology
[0002] Neodymium iron boron (NdFeB) is an important magnetic material, an alloy composed of neodymium, iron, and boron. It belongs to the rare-earth permanent magnet category and possesses excellent magnetic properties such as extremely high energy product and coercivity. NdFeB can store a large amount of magnetic energy in a relatively small volume, making it outstanding in many applications requiring strong magnetic fields. NdFeB effectively resists interference and demagnetization from external magnetic fields, ensuring stable magnetism even in complex operating environments.
[0003] The production process of sintered NdFeB magnets generates a certain amount of waste. Directly discarding this waste not only wastes valuable rare earth resources but may also cause environmental pollution. Using a waste recycling and reuse device for sintered NdFeB production can effectively improve resource recovery rates and achieve resource recycling.
[0004] Since the waste from sintered NdFeB production may have a lot of dust on its surface, direct recycling will result in impurities and impure output. Therefore, the waste from sintered NdFeB production needs to be cleaned first. However, simply rinsing with water may not be effective. Utility Model Content
[0005] To overcome the above shortcomings, this utility model provides a crushing device for recycling and reusing waste from sintered NdFeB production, which aims to improve the problem that washing sintered NdFeB production waste with water alone may not be effective.

[0027] Specifically, the support frame 2 can fix the motor 3. Starting the motor 3 can drive the turntable 4 to rotate. The turntable 4 drives the swing arm 5 to swing. The sliding frame 6 follows the rotation of the swing arm 5. The support frame 2 supports the rotation of the sliding frame 6. At the same time, the swing arm 5 can slide inside the sliding frame 6. The fixing frame 1 fixes the motor 7. Starting the motor 7 drives the gear 8 at the output end to rotate. The gear 8 meshes with the gear 9 and rotates. The gear 9 drives the cleaning basin 10 on the upper surface to rotate. The outer wall of the cleaning basin 10 is equipped with a drain pipe. A filter screen can be installed inside the drain pipe to reduce the loss of neodymium iron boron.
[0028] Reference Figure 1 The water outlet assembly includes a water tank 11, the lower surface of which is disposed on the upper surface of the fixing frame 1. A water pump 12 is fixedly connected inside the water tank 11, and a water outlet pipe 13 is fixedly connected to the output end of the water pump 12. The water outlet pipe 13 is located on the upper side of the washing basin 10.
[0029] Specifically, starting the water pump 12 can draw water from inside the water tank 11, and the water flows out from the outlet pipe 13 and into the washing basin 10.
[0030] Reference Figures 2-4 A primary crushing box 14 is fixedly connected to the lower surface of the fixed frame 1. An opening and closing plate 15 is slidably connected inside the primary crushing box 14. A fine crushing box 16 is fixedly connected to the lower surface of the primary crushing box 14.

[0034] Working principle: When using this device, firstly, the waste material from sintered NdFeB production is placed into the cleaning basin 10. Then, the water pump 12 is started to draw water from the water tank 11, and the water flows into the cleaning basin 10 from the outlet pipe 13. The motor 3 is started to drive the turntable 4 to rotate, which in turn drives the swing arm 5 to swing. As the swing arm 5 swings, the sliding frame 6 rotates accordingly, allowing the swing arm 5 to slide inside the sliding frame 6. Simultaneously, the motor 7 is started to drive the gear 8 to rotate, which in turn drives the cleaning basin 10 to rotate via the gear 9. As the cleaning basin 10 rotates, the swing arm 5 swings back and forth inside the basin, tumbling and washing the sintered NdFeB production waste. A drain pipe is installed on the outer wall of the cleaning basin 10. After the sintered NdFeB production waste is cleaned... Pulling the opening and closing plate 15 slides the sintered NdFeB production waste down into the primary crushing box 14. The starting motor 3 17 drives the first rotating wheel 18 to rotate. The first rotating wheel 18 drives the crusher 20 to rotate through the connecting rod 19.
