A method of using a pretreatment device for NdFeB waste material before roasting, including:

Wash the waste, the waste falls from the feed tank into the washing device, then pour the cleaning liquid from the pouring pipe into the washing device, start the first telescopic cylinder, the first telescopic cylinder shrinks back and forth, so that the shaking is supported on the base Shake left and right to drive the waste and cleaning fluid to mix well for 10-15 minutes;

Lead out the waste, start the first motor, the first motor rotates the first gear, the first gear drives the arc-shaped gear rod, and the bottom plate is turned down on both sides, so that the cleaned waste water flows out through the filter, from the bottom plates on both sides to the middle Flow down to the water outlet, and then start the second motor. The second motor turns the gusset down, and the drive motor drives the second gear to rotate. The long rack is moved down and the front plate slowly flips down while fitting the rollers. , So that the front plate is placed on the crushing box, start the servo motor, drive the baffle plate to rotate, make the baffle plate block on both sides of the front plate, and finally start the oil cylinder, which pushes the rear plate forward to push out the waste. Slide the waste from the front panel into the crushing box;

Crush the waste. The waste is squeezed and crushed under the rotation of the crushing reamer, so that the waste falls into small solid particles and falls on the inclined plate. Under the vibration of the vibrator, the waste falls from the inclined plate to the conveyor belt;

The waste is roasted, and the conveyor belt transfers the waste to the feeding tray. The lead screw motor and the second telescopic cylinder are activated. The lead screw motor drives the moving base to move back and forth. The second telescopic cylinder drives the dispersing gripper to rotate, so that the gripper disperses the waste. , And then start the third motor to drive the movable frame to move to the roasting device for roasting treatment.
