Description

Technical Field

[0001] The utility model belongs to the technical field of magnetic separation mechanisms, and relates to a magnetic separation mechanism for a magnetic separator of recycled plastic particles. Background Art

[0002] During the process of recycling and reproducing plastic substances, metal substances are often mixed in them. Therefore, a magnetic separation mechanism is needed to screen out the metal substances from the granular plastics. The material is evenly fed to the upper magnetic field area of the rotating semi-magnetic drum through a mechanical swing feeding device. The magnetic substances are adsorbed on the surface of the drum and rotate with the drum. Since the magnetic force received by the magnetic material and the non-magnetic material in the magnetic field is different, the magnetic particles are adsorbed on the surface of the drum by the magnetic force in the magnetic field and are carried to the non-magnetic field area and thrown off. The non-magnetic and weakly magnetic particles have different throwing-off trajectories due to the different magnetic forces they receive. The stronger the magnetism, the closer to the periphery of the drum during throwing off.

[0003] When the existing plastic particles are screened for metal substances by a magnetic separator, due to a large number of plastic particles mixed with metal particles moving along the drum, some metal particles move along with the piled-up plastic particles, resulting in that the metal particles far from the drum cannot be effectively adsorbed by the magnetic field area of the drum. Thus, there are still a small amount of metal substances mixed in the plastic particles flowing out along the feeding bin. Therefore, multiple filtrations are required later, reducing the working efficiency. Summary of the Utility Model

Support legs 63 are installed at both ends of the screw rod 6, and a movable block 7 is installed through it. A slider 71 is installed on the movable block 7. A groove 72 that runs through the outer wall is provided on the movable block 7, and a magnet 73 is installed in the groove 72.

[0027] Combination Figure 1 , Figure 3 As shown, the motor 22 is electrically connected to an external power source, and a pulley 61 is installed at one end of the rotating shaft of the motor 22. The pulley 61 at the motor 22 and the screw rod 6 are of different sizes.

[0028] Furthermore, the motor 22 here can be a servo motor, which can rotate forward and reverse regularly according to the set program. The size of the pulley 61 at the motor 22 is larger than that at the screw 6. At the same time, the two pulleys 61 are of different sizes and maintain a certain distance to keep the belt 62 in a taut state to meet the transmission requirements.

[0029] Combination Figure 1 , Figure 3 As shown, the motor 22 and the screw rod 6 are connected via a pulley 61 and a belt 62 , the lower bin 3 is installed obliquely at the discharge port 21 , and the rectangular groove 31 is larger than the sleeve 5 .

[0030] Furthermore, the rectangular groove 31 is larger than the sleeve 5 to prevent subsequent metal particles from being blocked by the rectangular groove 31 when moving along the sleeve 5. The sleeve 5 should be made of non-metallic material.

[0031] Combination Figure 1 , Figure 3 As shown, the bracket 4 has a U-shaped shape, the pipe joint 41 and the sleeve 5 are fixedly connected, and there is a gap between the two ends of the sleeve 5 and the pipe joint 41 , and the discharge port 43 is located directly below the stripping plate 51 .

[0032] Further, the pipe joint 41 is used to support the sleeve 5. Meanwhile, the material discharging port 43 is used for the downward movement of the separated metal particles to prevent scattering, and a hopper can be placed below here to receive the materials.

[0033] Combined with Figure 1 、 Figure 3 As shown, the size of the material discharging port 43 is larger than that of the stripping plate 51. The inner wall of the material discharging port 43 is inclined. Meanwhile, the outer shape of the stripping plate 51 is annular, and there is a spacing between the stripping plate 51 and the material discharging bin 3.

[0034] Further, when the internal movable block 7 moves to the outside of the stripping plate 51, the metal particles on the sleeve 5 are blocked by the stripping plate 51, and after the metal particles leave the magnetic region of the internal magnet 73, they fall into the material discharging port 43.

[0035] Combined with Figure 1 、 Figure 4 As shown, both ends of the lead screw 6 are rotatably connected to the support legs 63. The pulley 61 is located between the support legs 63 and the sleeve 5. Meanwhile, the spacing between the pulley 61 and the sleeve 5 is larger than that of the movable block 7.

[0036] Further, the spacing between the pulley 61 and the sleeve 5 is larger than that of the movable block 7, which means that the movable block 7 can move to this area here, and then there is enough spacing between the movable block 7 and the stripping plate 51 for the metal particles to leave the magnetic region of the magnet 73 and be blocked by the stripping plate 51 to achieve material stripping.

[0037] Combined with Figure 1 、 Figure 4 As shown, the diameter of the lead screw 6 is smaller than the inner diameter of the sleeve 5. Meanwhile, the lead screw 6 is suspended in the sleeve 5, and the movable blocks 7 are symmetrically arranged on the lead screw 6.

[0038] Further, the movable blocks 7 are symmetrically arranged at both ends, so that the magnetic regions formed by the magnets 73 on the movable blocks 7 can effectively adsorb the metal substances in the plastic particles.

[0039] Combined with Figure 1 、 Figure 5 As shown, the lead screw 6 is provided with threads in opposite directions. Meanwhile, the inner wall of the through part of the movable block 7 on the lead screw 6 is provided with threads that mesh with it, and the movable block 7 is in contact with the sleeve 5.

[0040] Further, the rotation of the lead screw 6 drives the movable block 7, so that the movable block 7 can slide along the slideway 52 inside the sleeve 5 through the sliders 71 at both ends.

[0041] Combined with Figure 1 、 Figure 5As shown, the slideways 52 are symmetrically arranged, the sliders 71 are symmetrically arranged at both ends of the movable block 7, and the movable block 7 is slidably connected to the slideways 52 through the sliders 71. The grooves 72 are arranged at intervals, and the number of the grooves 72 is four. The magnets 73 are flush with the outer wall of the movable block 7.

[0042] Furthermore, the magnets 73 are flush with the outer wall of the movable block 7, which means that the magnets 73 are embedded in the grooves 72, and there are no protrusions on the outer wall of the movable block 7, enabling the movable block 7 to move smoothly along the inner wall of the sleeve 5.

[0043] The working principle of the present utility model is as follows:

[0044] Plastic mixed with metal substances can pass through the roller in the magnetic separator 2, and the magnetic substances are adsorbed on the surface of the roller and rotate with the roller. Due to the different magnetic forces exerted on magnetic materials and non-magnetic materials in the magnetic field, the magnetic particles are adsorbed on the surface of the roller by the magnetic force in the magnetic field and are carried to the non-magnetic field area and thrown off. A small part of the metal particles move with the accumulated plastic particles and are not adsorbed by the magnetic field area of the roller, so they move to the blanking bin 3 along with the plastic particles.

[0045] Plastic particles mixed with trace metal substances slide along the blanking bin 3 to the sleeve 5, and the internal metal substances are adsorbed on the outside of the sleeve 5 by the magnetic region formed by the magnets 73. During this period, the motor 22 drives the lead screw 6 to rotate regularly in both forward and reverse directions through the cooperation of the belt 62 and the pulley 61. Then, the movable block 7 reciprocates inside the sleeve 5 along the slideways 52 through the sliders 71. When the movable block 7 moves to the outside of the blanking plate 51, the metal particles get out of the control of the magnetic region formed by the magnets 73, and the metal particles are blocked by the blanking plate 51 and fall into the blanking port 43 to achieve separation, effectively improving the efficiency of screening metal substances.

Those skilled in the art to which the present utility model pertains can make various modifications or supplements to the described specific embodiments or use similar methods for substitution, but will not deviate from the spirit of the present utility model.
