[0023] Refer to Figures 1-4 , an electrostatic separation device for waste circuit boards, including a bottom plate frame 4. One side of the bottom plate frame 4 is fixedly connected with an electric telescopic rod 20 by bolts. One end of the telescopic part of the electric telescopic rod 20 passes through the bottom plate frame 4 and is fixedly connected with a connecting frame 16 by bolts. A plurality of sliding holes are opened at the top of the connecting frame 16, and sliders 19 are slidably connected in the plurality of sliding holes. The top of the slider 19 is welded with a frame 2. Two inclined plates 12 are fixedly connected in the frame 2 by bolts. The materials of the two inclined plates 12 are both iron, so that the inclined plates 12 have the function of conducting electricity. One side of the upper inclined plate 12 is provided with a ground wire 3, and the ground wire 3 passes through the frame 2. A plurality of filter holes 11 are opened on the upper surface of the upper inclined plate 12. A material collecting component for collecting the screened materials is arranged on one side of the frame 2. A material shaking component for shaking the frame 2 up and down is arranged on the inner wall of the bottom of the bottom plate frame 4. The crushed waste circuit boards are added to the frame 2. At this time, the crushed waste circuit boards will fall onto the inclined plates 12. The ground wire 3 on the inclined plates 12 will conduct the static electricity generated during the crushing of the waste circuit boards and export the static electricity. The filter holes 11 on the inclined plates 12 will screen the crushed waste circuit boards, so that the materials that meet the size will fall onto the lower inclined plates 12, thereby realizing the electrostatic separation of the waste circuit boards, and at the same time screening out the larger fragments to avoid affecting the next processing.

[0024] In the present utility model, the material shaking assembly includes two support plates 15. Both of the two support plates 15 are fixed to the bottom inner wall of the bottom plate frame 4 by bolts. A plurality of arc-shaped grooves 14 are formed at the tops of the two support plates 15. At positions corresponding to the two support plates 15 on the outer wall of the bottom of the frame 2, bumps 13 are welded. And the bumps 13 are inserted into the arc-shaped grooves 14. The two support plates 15 are respectively located on both sides of the connecting frame 16. Start the electric telescopic rod 20 to perform reciprocating movement of contraction and elongation. The electric telescopic rod 20 will drive the connecting frame 16 to move. The connecting frame 16 will drive the frame 2 to move through the slider 19. The frame 2 will drive the bump 13 to move. During the movement of the bump 13, under the action of the arc surface of the arc-shaped groove 14, the bump 13 will move upward. The bump 13 jacks up the frame 2 to move upward. When the bump 13 moves to above the next arc-shaped groove 14, under the action of gravity, the bump 13 will move downward into the arc-shaped groove 14. So on and so forth, so that the frame 2 shakes up and down during the reciprocating movement back and forth, thereby shaking the materials on the inclined plate 12, thus avoiding the blockage of the filter holes 11 by the materials, and can better screen the materials, improving the use effect of the electrostatic separation device;

[0025] The material receiving assembly includes a plurality of fixing plates 9. The plurality of fixing plates 9 are evenly and symmetrically welded to the outer walls on both sides of the frame 2. Installation grooves 10 are formed at the tops of the plurality of fixing plates 9. Fixing blocks are installed in the plurality of installation grooves 10. A material box 1 is welded between two opposite fixing blocks. And because the inclined plate 12 is in an inclined state, the materials on the inclined plate 12 will roll into the material box 1, so that the material box 1 collects the screened materials. An insertion assembly for fixing the material box 1 is provided in each of the plurality of fixing plates 9. The insertion assembly includes a chute 7. The chute 7 is formed on one side of the installation groove 10. A wedge-shaped block 8 is slidably connected in the chute 7. A clamping groove 5 is formed on one side of each of the plurality of fixing plates 9. And the wedge-shaped block 8 is inserted into the clamping groove 5. A spring 6 is welded to one side of the wedge-shaped block 8. And the spring 6 is fixed to the fixing plate 9. The two material boxes 1 are respectively located below the two inclined plates 12. Pull the wedge-shaped block 8 to move, so that the wedge-shaped block 8 is separated from the clamping groove 5. At this time, the material box 1 can be disassembled to process the materials collected in the material box 1. A plurality of grooves are formed at the bottom of the connecting frame 16. A plurality of balls 18 are provided in the plurality of grooves. A plurality of grooves 17 are formed on the bottom inner wall of the bottom plate frame 4, so that the balls 18 roll along the grooves of the grooves 17. During the movement of the connecting frame 16, the balls 18 will roll along the grooves 17, thereby reducing the friction of the movement of the connecting frame 16.

[0026] Working principle: When in use, add the shredded waste circuit boards onto the frame 2. At this time, the shredded waste circuit boards will fall onto the inclined plate 12. The ground wire 3 on the inclined plate 12 will conduct the static electricity generated during the shredding of the waste circuit boards and export the static electricity. The filter holes 11 on the inclined plate 12 will screen the shredded waste circuit boards, allowing the materials that meet the size requirements to fall onto the inclined plate 12 below, thus realizing the electrostatic separation of the waste circuit boards. At the same time, the larger fragments are screened out to avoid affecting the next processing. Also, since the inclined plate 12 is in an inclined state, the materials on the inclined plate 12 will roll into the material box 1, enabling the material box 1 to collect the screened materials. Meanwhile, start the electric telescopic rod 20 to perform reciprocating movement of contraction and elongation. The electric telescopic rod 20 will drive the connecting frame 16 to move. The connecting frame 16 will drive the frame 2 to move through the slider 19. The frame 2 will drive the convex block 13 to move. During the movement of the convex block 13, under the action of the arc surface of the arc-shaped groove 14, the convex block 13 will move upward, and the convex block 13 will jack up the frame 2 to move upward. When the convex block 13 moves above the next arc-shaped groove 14, under the action of gravity, the convex block 13 will move downward into the arc-shaped groove 14. This cycle repeats, so that the frame 2 will jitter up and down during the reciprocating movement back and forth, thus jittering the materials on the inclined plate 12, avoiding the blockage of the filter holes 11 by the materials, and better screening the materials, improving the use effect of the electrostatic separation device.
