s2: the neodymium iron boron waste and the cleaning agent rotate clockwise in the cleaning cylinder to be beaten and mixed, and the rotating waste falls off under the action of gravity and collides with the convex strips 301 to cause the falling of impurities when being brought to the top end by the grooves 302 from bottom to top;

s3: when the magnetic strips 401 in the track 4 rotating counterclockwise rotate to the outer side of the groove 302, the neodymium iron boron waste in the cleaning cylinder 3 is temporarily adsorbed and fixed in the groove 302 under the action of magnetic force, so that impurities on one side of the outer surface of the waste are brushed off by the cleaning brush 3041 rotating at a higher speed;

s4: after the cleaned waste materials are screened and collected by the screen 502, proper and clean waste materials are collected by the material collecting rack 5, fine impurities and waste water flow into the material distributing chamber 6, solid particle impurities are rotated by the material distributing shaft 601 and the blades 602, then the solid particle impurities press the baffle 6032 to open the outlet 6033 under the action of centrifugal force, the outlet 6033 slides out through the material discharging channel 8 and is collected by the solid collecting tank 801, and liquid is collected by the liquid collecting tank 902 after the liquid outlet hole 9 is opened;

s5: disconnecting an external power supply, taking out the clean neodymium iron boron waste material, drying, and then putting into the next process, and performing harmless treatment on solid impurities and wastewater respectively;

s6: the method comprises the steps of putting dried neodymium iron boron waste into a crushing chamber 11 through a blanking hopper 1101 for crushing, taking out the crushed neodymium iron boron waste through a material receiving chamber 12, putting the crushed neodymium iron boron waste and a pre-smelted auxiliary material alloy thin strip into a hydrogen crushing chamber 13 for hydrogen crushing to obtain coarse powder, mixing the coarse powder with an antioxidant, putting the mixture into an air grinding chamber 14 for air grinding to obtain fine powder, putting the fine powder, the antioxidant and gasoline into a stirring chamber 15 for mixing and stirring, putting the mixed fine powder into a compression chamber 16 for compression molding, and finally putting the compression chamber 17 for sintering to prepare the regenerated bonded magnet.

The specific working principle of the invention in the implementation process is as follows:

when the work is not started, the baffle 6032 is normally closed at the outlet 603 and is in a normal state, and the outlet 6033 is not opened;

when the machine starts working, the machine is communicated with an external power supply, after neodymium iron boron waste materials needing to be cleaned are poured with water and a cleaning agent, the control switch 10 is pressed, and by utilizing the principle that a roller washing machine is used for cleaning clothes, the neodymium iron boron waste materials rotating in the cleaning cylinder 3 fall and beat on the raised lines 301 under the action of gravity when being brought to the upper end by the grooves 302, so that impurities on the neodymium iron boron surface of the machine and the raised lines 301 collide and rub with each other under the combined action of the cleaning agent to fall off;

since the track 4 is provided on the outer wall of the cleaning cylinder 3 to rotate around, when the track 4 and the cleaning cylinder 3 rotate with each other (the cleaning cylinder 3 rotates clockwise, the track 4 rotates counterclockwise), by using the principle of intermittent magnetic control, i.e. the magnetic strip 401 in the track 4 rotates to the outside of the groove 302 on the cleaning cylinder 3 (the magnetic control is turned on), because the neodymium iron boron waste materials are magnetic, the neodymium iron boron waste materials can gather in the groove 302 and are temporarily adsorbed by the magnetic strips 401 at the outer side, during this period of suction, the cleaning brush 3041 rotating at a high speed brushes across the groove 302, thereby brushing off impurities on one side of the surface of the neodymium iron boron waste material in the cleaning cylinder, when the impurities are rotated to the outer side of the convex strip 301 on the cleaning cylinder 3 (the magnetic control is disconnected) next to the magnetic strip 401 in the track 4, will successively drive the neodymium iron boron waste material adsorbed before to collide with the raised strips 301 and break away from the inner wall of the cleaning cylinder 3, the cleaning process is continued, and the impurities on the surfaces of the neodymium iron boron waste can be cleaned by repeated operation;

because the plurality of outlet holes 603 and the baffle 6032 are arranged on the outer surface of the material distribution chamber 6, when the screened fine solid particle impurities and the waste water are stirred by the blades 602 in the material distribution chamber 6, the solid particle impurities stirred in the material distribution chamber 6 have larger mass and higher rotating speed than liquid by utilizing the principles of centrifugal force and inertia, so the solid particle impurities are more easily thrown onto the inner wall surface of the material distribution chamber 6, and when the solid particles contact the baffle 6032 at the outlet holes 603 on the inner wall of the material distribution chamber 6, the baffle 6032 made of plastic is pressed under the inertia effect of the baffle 6032 to deform, the outlet 6033 is opened, the process is an instant process, so the solid particle impurities are discharged and collected, and the baffle 6032 is instantly restored to close the outlet 6033 and continuously block the outlet holes 603 to prevent the waste water from discharging, so the solid-liquid separation can be realized;

in the working process of the invention, the rotating speed of the cleaning rotating shaft 303 is greater than that of the cleaning cylinder 3, the baffle 6032 is made of plastic, the steps of cleaning neodymium iron boron waste materials, separating solid from liquid and the like which are generated in the cleaning cylinder 3, the track 4 and the distribution chamber 6 can conveniently clean impurities on the surface of the neodymium iron boron waste materials through the common driving action of the principles of friction, intermittent magnetic control, centrifugal force, inertia and the like, and the impurities on the surface of the neodymium iron boron waste materials can be conveniently cleaned in the cleaning process of the neodymium iron boron waste materials, and the cleaned fine solid impurities and turbid liquid can realize solid-liquid separation, so that the cleanliness of the waste materials and the separation of the solid from the liquid are improved, the environment is protected, and then the separated neodymium iron boron waste materials are regenerated into bonded magnets through.

The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, it is possible to make several variations and modifications without departing from the concept of the present invention, and these should be considered as the protection scope of the present invention, which will not affect the effect of the implementation of the present invention and the utility of the patent.
