Specifically, the bottoms of the left baffle 103 and the right baffle 104 form a rectangular extending edge, the filter screen 118 is fixed by the extending edge, a sealing strip is arranged at the bottom of the extending edge and attached to the bottom plate 112, and the front portions of the left baffle 103 and the right baffle 104 are also provided with sealing strips attached to the front plate 105.

A use method of a pretreatment device before roasting neodymium iron boron waste materials comprises the following steps:

cleaning waste, namely, the waste falls into the washing device 1 from the feeding groove 101, then cleaning solution water is poured into the washing device 1 from the water pouring pipe 102, the first telescopic cylinder 117 is started, the first telescopic cylinder 117 contracts back and forth, the shaking frame 107 shakes left and right on the base 108, and the waste and the cleaning solution are driven to be fully mixed for 10-15 minutes;

the waste is led out, the first motor 116 is started, the first motor 116 rotates the first gear 115, the first gear 115 drives the arc-shaped toothed bar 1121, the bottom plate 112 is turned over towards the lower two sides, the cleaned waste water flows out through the filter screen 118 and flows downwards from the bottom plates 112 towards the middle to the water outlet groove 111, then the second motor 1074 is started, the buckle plate 1073 is turned over by the second motor 1074, the driving motor drives the second gear 205 to rotate, the long toothed bar 204 descends and moves, the front plate 105 slowly turns over under the condition of being attached to the roller 2041, the front plate 105 is lapped on the crushing box 301, the servo motor is started to drive the material blocking plate 201 to rotate, the material blocking plate 201 is blocked at the two sides of the front plate 105, finally the oil cylinder 110 is started, and the oil cylinder 110 pushes the rear plate 106 to advance, so that the waste is pushed out. Sliding the waste material from the front plate 105 into the crushing bin 301;

crushing the waste, extruding and crushing the waste under the rotation of the crushing reamer 303, so that the waste is solid particles and falls onto the inclined plate 304, and dropping the waste from the inclined plate 304 onto the conveyor belt 302 under the vibration of the vibrator 305;

and (3) roasting the waste materials, wherein the waste materials are conveyed to a feeding plate 406 by a conveying belt 302, a lead screw motor 405 and a second telescopic cylinder 404 are started, the lead screw motor 405 drives a moving seat 402 to move back and forth, the second telescopic cylinder 404 drives a scattering hand grip 403 to rotate, so that the waste materials are scattered by the hand grip, and then a third motor 408 is started to drive a moving frame 407 to move to a roasting device 5 for roasting treatment.
