[0030] The structure of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1

[0032] As Figures 1 to 5 shown, a neodymium iron boron waste pretreatment cleaning device provided by an embodiment of the present invention includes a cleaning tank 1, the cleaning tank 1 is fixedly installed on the underframe 5, a feeding port 11 and a discharging port 12 are respectively arranged at the upper and lower ends of the cleaning tank 1, a filter screen 13 is arranged inside the cleaning tank 1, a water inlet pipe 4 is arranged in the feeding port 11, a cleaning mechanism 2 is arranged inside the cleaning tank 1, and a scraping mechanism 3 is arranged on the cleaning mechanism 2.

[0033] Furthermore, a water flow channel 14 is arranged between the filter screen 13 and the inner wall of the cleaning tank 1, and an openable discharging mesh 15 is arranged at the bottom of the filter screen 13.

[0034] In this application, the water inlet pipe 4 is connected to an external water supply system. The water inlet pipe 4 includes a main pipe and a plurality of branch pipes, and a nozzle is arranged at the end of each branch pipe. The neodymium iron boron waste enters the cleaning tank 1 from the feeding port 11, the water inlet pipe 4 injects water into the cleaning tank 1, the cleaning mechanism 2 cleans the waste, the cleaned waste is filtered by the filter screen 13, and the waste water flows out through the water flow channel 14. The discharging mesh 15 is opened to discharge the cleaned waste.

[0035] Further, the cleaning mechanism 2 includes an outer ring 21 and an inner ring 22. The outer ring 21 and the inner ring 22 are rotatably installed in the cleaning tank 1. The outer ring 21 and the inner ring 22 are fixedly connected. A number of outer cleaning brushes 23 and inner cleaning brushes 24 are respectively arranged circumferentially on the outer ring 21 and the inner ring 22. The outer cleaning brushes 23 and the inner cleaning brushes 24 are arranged alternately, which can clean the waste more comprehensively, improve the cleaning effect. One end of the inner ring 22 is fixedly connected with a rotating seat 29. A transmission gear ring 210 is fixedly installed on the rotating seat 29. One side of the transmission gear ring 210 is meshed with a first gear 211. The first gear 211 is fixedly connected to the output end of the motor 28. The working motor 28 drives the first gear 211 and the transmission gear ring 210 to rotate, so that the inner ring 22 and the outer ring 21 drive the inner cleaning brushes 24 and the outer cleaning brushes 23 to rotate. On the one hand, the neodymium iron boron waste is stirred to make it dispersed. On the other hand, it is cleaned, improving the cleaning efficiency and enhancing the cleaning effect.

[0036] Further, an electromagnet assembly 25 is fixedly installed in the middle of the cleaning tank 1. One end of the electromagnet assembly 25 is fixedly connected with a fixed seat 26. The rotating seat 29 is rotatably sleeved on the fixed seat 26. One end of the cleaning tank 1 is fixedly connected with a fixed frame 27. The fixed seat 26 and the motor 28 are both fixedly installed on the fixed frame 27.

[0037] Turn on the electromagnet assembly 25 to adsorb small-particle neodymium iron boron waste during the cleaning process, further improving the recovery rate of the waste, and realizing the synchronous adsorption and cleaning of impurities, shortening the overall cleaning time.

[0038] Further, the scraping mechanism 3 includes an electric push rod 31 and a telescopic rod 33. The electric push rod 31 and the telescopic rod 33 are respectively fixedly installed on both sides of the cleaning tank 1. The output end of the electric push rod 31 and one end of the telescopic rod 33 are both fixedly connected with a connecting plate 32. A guide rod 35 is fixedly connected to the middle of the connecting plate 32. The guide rod 35 slidably penetrates through one side of the cleaning tank 1, and the end is fixedly connected with an annular scraping plate 34. The annular scraping plate 34 is slidably sleeved on the electromagnet assembly 25.

[0039] After the cleaning is completed, turn off the electromagnet assembly 25 and start the electric push rod 31. Drive the connecting plate 32 and the guide rod 35 to move through the electric push rod 31, so as to push the annular scraping plate 34 to slide on the electromagnet assembly 25, scrape off the neodymium iron boron waste adsorbed on the electromagnet assembly 25, and realize the automatic cleaning of the electromagnet assembly 25 and the feeding of the waste.

[0040] Embodiment 2

[0041] On the basis of Embodiment 1, add the following content: Refer to Figures 1 - 8The annular scraper 34 is rotatably connected to a first shifting ring 6 on its outer side, and a first receiving hole 61 is provided inside the first shifting ring 6, and the outer cleaning brush 23 and the inner cleaning brush 24 are both located in the first receiving hole 61. When cleaning the electromagnet assembly 25, the annular scraper 34 can simultaneously clean the outer cleaning brush 23 and the inner cleaning brush 24 through the first shifting ring 6 (the first receiving hole 61 scrapes the outer cleaning brush 23 and the inner cleaning brush 24).

[0042] Example 3

[0043] Different from the embodiment 1, the implementation method of the scraping mechanism 3 is different, as follows:

[0044] See also Figure 9 and Figure 10 The electromagnet assembly 25 includes a cylinder and a magnet block arranged inside the cylinder, and an external thread is provided on the outer surface of the cylinder; the scraper mechanism 3 includes a threaded cylinder 36 and a second shifting ring 37, the threaded cylinder 36 and the second shifting ring 37 are fixedly connected, and a second accommodating hole 38 is provided inside the second shifting ring 37, and the outer cleaning brush 23 and the inner cleaning brush 24 are both located in the second accommodating hole 38.

[0045] Since the electromagnet assembly 25 does not rotate, when the outer cleaning brush 23 and the inner cleaning brush 24 rotate synchronously, the second shifting ring 37 will shift the threaded barrel 36 to rotate, thereby realizing the axial movement of the threaded barrel 36 and the second shifting ring 37. During the axial movement, the threaded barrel 36 can clean the debris on the outer surface of the electromagnet assembly 25, and the second shifting ring 37 can clean the debris attached to the outer cleaning brush 23 and the inner cleaning brush 24. It should be noted that in this solution, it is necessary to make the outer cleaning brush 23 and the inner cleaning brush 24 rotate forward for several turns first, and then reverse for several turns, so as to realize the reciprocating axial movement of the threaded barrel 36 on the electromagnet assembly 25. And in this process, the second shifting ring 37 can reciprocate the material to improve the cleaning effect.

[0046] Furthermore, a discharge channel 251 is provided inside the electromagnet assembly 25, and a strip hole 252 communicating with the discharge channel 251 is provided on the electromagnet assembly 25, and the strip hole 252 is located at the side of the electromagnet assembly 25. When the material is moved, the debris can be moved to the discharge channel 251 through the strip hole 252. The end of the discharge channel 251 is connected to the outside world, and the impurities in the discharge channel 251 can be discharged regularly. It should be noted that during cleaning, the liquid level cannot exceed the strip hole 252.

[0047] Example 4

[0048] Different from the first embodiment, the outer ring 21 and the inner ring 22 are not fixedly connected, as follows:

[0049] See alsoFigure 2 , Figure 11 and Figure 12 , the outer surface of the inner ring 22 is provided with an external gear ring 71, the inner surface of the outer ring 21 is provided with an internal gear ring 72, and the inner side of the end wall of the cleaning tank 1 is rotatably connected with a second gear 73. The second gear 73 meshes with the external gear ring 71 and the internal gear ring 72. Through this setting, the outer ring 21 and the inner ring 22 can rotate in opposite directions, and the neodymium iron boron waste can be toggled in the opposite direction, thereby improving the cleaning efficiency.

[0050] Furthermore, the outer cleaning brush 23 is rotatably connected to the outer ring 21, the inner cleaning brush 24 is rotatably connected to the inner ring 22, and a dial plate 74 is fixedly connected to the second gear 73. The dial plate 74 can be attached to the outer cleaning brush 23 and the inner cleaning brush 24. Through this setting, not only can the above functions be realized, but also the inner cleaning brush 24 and the outer cleaning brush 23 can be cleaned by the dial plate 74 at the same time.

[0051] The working principle of the present invention:

[0052] The neodymium iron boron waste enters the cleaning tank 1 from the feed port 11, the water inlet pipe 4 injects cleaning water, the motor 28 drives the outer ring 21 and the inner ring 22 of the cleaning mechanism 2 to rotate, the outer cleaning brush 23 and the inner cleaning brush 24 clean the waste. At the same time, the electromagnet assembly 25 is energized to adsorb small particle neodymium iron boron waste. During the cleaning process, water and impurities flow down through the water flow channel 14. After the cleaning is completed, the blanking net 15 is opened, and the waste is discharged from the discharge port 12. The electric push rod 31 drives the annular scraper 34 of the scraping mechanism 3 to slide on the electromagnet assembly 25, and scrapes off the adsorbed impurity neodymium iron boron waste. To sum up: For this neodymium iron boron waste pretreatment and cleaning device, through the staggered inner cleaning brush 24 and outer cleaning brush 23, the neodymium iron boron waste can be comprehensively and effectively cleaned. By setting the electromagnet assembly 25 to adsorb small particle waste, the recovery rate of the waste can be improved, and the cleaning and adsorption are carried out simultaneously, improving the processing efficiency.
