[0002] In the rare earth permanent magnet material processing process, rare earth permanent magnet waste slag materials are generated, and some rare earth permanent magnet particles are mixed in these waste slags. However, these waste slags are usually discharged directly through the waste pipeline, so that the rare earth permanent magnet particles in the waste slags are also lost, resulting in a waste of rare earth permanent magnet materials. If they are directly discharged, they will also cause pollution and harm the environment. Therefore, technical personnel in this field have proposed a device for recycling rare earth permanent magnet materials.

[0028] In this embodiment, the stirring device includes a first lifting mechanism 6, a first mounting frame 3, a first drive motor 4 and a stirring roller 5. Two first lifting mechanisms 6 are installed at the top of the machine body 1, and two first mounting frames 3 are respectively connected to the lower ends of the first lifting mechanisms 6. The stirring roller 5 is rotatably connected between the bottoms of the two first mounting frames 3 and is located above the conveyor belt 2. The stirring roller 5 is horizontal and perpendicular to the length direction of the conveyor belt 2. The first drive motor 4 is fixed to one side of one of the first mounting frames 3 away from the stirring roller 5, and the output shaft of the first drive motor 4 is fixedly connected to the stirring roller 5, which is used to drive the stirring roller 5 to rotate. Specifically, the first lifting mechanism 6 is a hydraulic push rod or an electric push rod.

[0029] By providing a stirring device, the stirring roller 5 rotates under the drive of the first driving motor 4, and can stir the waste residue on the conveyor belt 2, so that the adsorption device can adsorb the rare earth permanent magnetic material. By providing a first lifting mechanism 6, the first lifting mechanism 6 can drive the stirring roller 5 to rise and fall, which is convenient for use.

[0030] In this embodiment, the adsorption device includes a second lifting mechanism 10, a second mounting frame 7, a second drive motor 8 and a magnetic roller 9. Two second lifting mechanisms 10 are installed at the top of the machine body 1, and two second mounting frames 7 are respectively connected to the lower ends of the second lifting mechanisms 10. The magnetic roller 9 is rotatably connected between the two second mounting frames 7 and is located above the conveyor belt 2. The magnetic roller 9 is horizontally and perpendicular to the length direction of the conveyor belt 2. The second drive motor 8 is fixed to one side of one of the second mounting frames 7 away from the magnetic roller 9, and the output shaft of the second drive motor 8 is fixedly connected to the magnetic roller 9 for driving the magnetic roller 9 to rotate. Specifically, the second lifting mechanism 10 is a hydraulic push rod or an electric push rod.

[0031] In this embodiment, a linear motion mechanism 11 is provided at the top of the inner side of the machine body 1, and the linear motion mechanism 11 is connected to the upper end of the second lifting mechanism 10, and is used to drive the second lifting mechanism 10 to move to the side of the conveyor belt 2. A collection box 12 with an upper end opening is provided on the side of the conveyor belt 2, so as to facilitate the cleaning of the rare earth permanent magnetic material adsorbed on the magnetic roller 9 into the collection box 12 for collection. Specifically, the linear motion mechanism 11 is an electric slide or an electric cylinder slide, and two sliders that move synchronously are provided on the electric slide, and the two second lifting mechanisms 10 are respectively connected to the two sliders.

[0032] In this embodiment, the magnetic roller 9 is an electromagnetic adsorption roller, which generates magnetic force when powered on and can adsorb rare earth permanent magnetic materials, and loses magnetic force when powered off.

[0033] The magnetic roller 9 adopts an electromagnetic adsorption roller. By setting a cleaning device corresponding to the adsorption device above the collection box 12, after the magnetic roller 9 adsorbs the rare earth permanent magnetic material, it moves to the top of the collection box 12 through the linear motion mechanism 11. After the power is cut off, the magnetic roller 9 loses its magnetism and cannot continue to adsorb the rare earth permanent magnetic material.

[0035] The working principle of the belt-type recovery machine for rare earth permanent magnetic materials in this embodiment is:

[0036] The rare earth permanent magnetic waste slag material enters the machine body 1 through the feed port of the conveyor belt 2. Two sets of stirring devices and adsorption devices are arranged in the machine body 1. After two processes of stirring first and then adsorption, the rare earth permanent magnetic materials in the rare earth permanent magnetic waste slag material are fully adsorbed. The adsorbed magnetic roller 9 moves to the top of the collection box 12 under the drive of the linear motion mechanism 11. The magnetic roller 9 loses its magnetism after power failure and cannot continue to adsorb the rare earth permanent magnetic materials. The rare earth permanent magnetic materials fall into the collection box 12 under the action of gravity. The cleaning device can clean the magnetic roller 9 after power failure, so that the rare earth permanent magnetic materials adsorbed by the magnetic roller 9 fall into the collection box 12 for collection.
