[0033] A sliding hole is formed on the second support plate 11. Two first sliding grooves are symmetrically formed on the inner walls of both sides of the sliding hole. Two sliders are symmetrically and fixedly installed on the baffle 1401. The sliders are slidably connected to the inner walls of the corresponding first sliding grooves.

[0034] The two snap mechanisms 15 include two third chambers 1501 which are respectively formed on the two carrier plates 12. A rotating rod 1502 is movably installed on the carrier plate 12. One end of the rotating rod 1502 extends into the third chamber 1501 and is fixedly installed with a connecting block 1503. A limiting hole 1504 is formed on the carrier plate 12.

[0037] In this embodiment, when in use, first remove the first cover plate 3, put the waste circuit board powder to be screened into the material loading tank 6, then install the first cover plate 3, start the blower 8 to blow the waste circuit board powder into the separation box 4, and at the same time start the first motor 405 to drive the second bevel gear 406 to rotate. The second bevel gear 406 drives the first bevel gear 404 to rotate, the first bevel gear 404 drives the support rod 402 to rotate, the support rod 402 drives the electromagnet 403 to rotate. When the electromagnet 403 rotates, it adsorbs the strongly magnetic powder in the waste circuit board, so that the strongly magnetic powder can be separated from the waste circuit board powder, while the ceramic powder and resin powder fall into the first housing 9. At the same time, open the water inlet pipe to let water in. The ceramic powder precipitates in the water, and the precipitated ceramic powder will fall into the carrier plate 12. The resin powder floats or suspends in the water. Start the second motor 1404 to drive the fourth bevel gear 1405 to rotate.

The water flow drives the resin powder through the through hole 1406, so that the ceramic powder and resin powder can be screened and separated. Through the two third connecting pipes fixedly installed on the inner wall of the bottom of the first housing 9, the screened water can be discharged, which is convenient for removing the two carrier plates 12.

[0038] When removing the carrier plate 12, first press and rotate the rotating rod 1502 at the same time. The rotating rod 1502 drives the connecting block 1503 and the limiting rod 1505 to rotate while moving. The limiting rod 1505 engages with the inner wall of the limiting hole 1504, so that the rotating rod 1502 and the connecting block 1503 do not move and rotate under the action of the compression spring. At the same time, the connecting block 1503 drives the support column 1507 to move, the support column 1507 drives the positioning rod 1508 to move, and the positioning rod 1508 separates from the inner wall of the positioning hole 1509, so that the carrier plate 12 can be removed, and the ceramic powder and resin powder can be collected.

[0039] In this embodiment, the separation box 4 is fixedly installed in the first installation groove 2, the first support block 5 is fixedly installed in the first installation groove 2, the first support block 5 is fixedly connected to the separation box 4, and the blower 8 is fixedly installed in the first chamber 7, which can disperse the waste circuit board powder to facilitate the electromagnet 403 to adsorb the strongly magnetic powder.
