Description

[0002] As a lightweight, corrosion-resistant metal, aluminum plays a vital role in many industries around the world. However, the primary production process of aluminum is energy-intensive. From the mining of bauxite to the refining of alumina and the production of electrolytic aluminum, the entire chain consumes a lot of energy. Therefore, the recycling and reuse of scrap aluminum has become an important way to save energy and reduce costs.

[0028] As a further explanation of this embodiment, the structure composed of the first pulley 31, the second pulley 32, the first connecting rod 14, the second connecting rod 15 and the third connecting rod 16 is symmetrically arranged in two groups on both sides of the sorting mechanism, and the two second connecting rods 15 are jointly fixed to the support frame 4, and the multiple separation claws 17 are installed in the support frame 4.

[0029] As a further explanation of this embodiment, a motor housing 40 is fixed in the middle of the support frame 4, and at least three groups of adjustment frames 41 are arranged on both sides of the motor housing 40.

[0031] A dual-axis motor 22 is fixed inside the motor housing 40, and the two output shafts of the dual-axis motor 22 are each coaxially fixed with one end of a screw 48, and the other ends of the two screws 48 are connected to the bearings of the support frame 4, and the screw 48 is threadedly connected to a nut 49, and the nut 49 is connected to a group of adjustment frames away from the motor housing 40, and the nut 49 is fixedly connected to a second slider 491, and the second slider 491 is movably arranged in a second guide rail 492, and the second guide rail 492 is fixed on the support frame 4.

[0032] As a further explanation of this embodiment, in a group of adjustment frames closest to the motor housing 40, the fourth connecting rod 410 is hinged to the motor housing 40, and a roller 60 is provided at one end of the fifth connecting rod 411 close to the motor housing 40, and the roller 60 is slidably set in a first sliding groove 61, and the first sliding groove 61 is fixed to the motor housing 40.

[0033] As a further explanation of this embodiment, in a group of adjustment frames farthest from the motor housing 40 , the fourth connecting rod 410 is hinged to the nut 49 through the sixth connecting rod 70 , and the fifth connecting rod 411 is hinged to the nut 49 through the seventh connecting rod 71 .

[0034] As a further explanation of this embodiment, the vibration mechanism includes a spring 80 fixed on the frame 1, the frame 1 is fixed to one end of the spring 80, the other end of the spring 80 is fixedly connected to a first baffle plate 83, the first baffle plate 83 is fixed to a cloth plate 81, the cloth plate 81 is located below the separation claw 17, a vibration plate 82 is fixed below the first baffle plate 83, and a vibration motor 84 is fixed on the vibration plate 82.

[0035] The material distribution plate 81 is tilted, and the angle between it and the horizontal line is 10°.

[0036] As a further explanation of this embodiment, a dividing plate 90 is arranged downstream of the first conveyor belt 12 , and the dividing plate 90 is fixed to a protective shell 91 , and the protective shell 91 is fixed on the frame 1 .

[0037] As a further explanation of this embodiment, the protective shell 91 is fixed to two second baffles 92 , and the two second baffles 92 are located on both sides of the first conveyor belt 12 . The second baffles 92 are also fixed to the frame 1 .

[0038] As a further explanation of this embodiment, at least two separation claws 17 are fixed to the lower end surface of the motor housing 40. Because the motor housing 40 has a certain width, fixing the separation claws 17 below the motor housing 40 can prevent the material below the motor housing 40 from being unable to be combed.

[0039] When using the device to sort a mixture of metal and non-metal, first start the vibration motor 84, the vibration motor 84 causes the vibration plate 82 to vibrate, so that the material on the cloth plate 81 moves toward the sorting mechanism; start the first motor 20 and the second motor 21, the first motor 20 drives the first conveying roller 10 to rotate, the first conveying roller 10 drives the first conveyor belt 12 to continue to transport the material downstream, and the second motor 21 drives the electromagnetic roller 13 to rotate. The magnetic field generated by the rotation of the electromagnetic roller 13 produces a repulsive force on the metal material in the material, so that the metal material can pass through the dividing plate 90, and the non-metal material will be blocked by the dividing plate 90.

[0040] The rotation of the first conveyor roller 10 will also drive the first pulley 31 to rotate, and drive the second pulley 32 to rotate through the belt transmission connection, thereby driving the first connecting rod 14 to revolve around the central axis of the second pulley 32, and further driving the third connecting rod 16 and the second connecting rod 15 to swing. Through the swing of the second connecting rod 15, the support frame 4 and the separation claw 17 are driven to move to comb and disperse the accumulated materials. The movement process of the separation claw 17 to comb and disperse the materials is from bottom to top, from close to the sorting mechanism to away from the sorting mechanism, and combing along the inclination of the cloth plate 81. Specifically, at the beginning, the hinge point of the first connecting rod 14 and the second connecting rod 15 is above the center point of the second pulley 32, and the hinge point and the center point are on the same vertical line. Then, the first connecting rod 14 rotates driven by the second pulley 32, driving the support frame 4 and the separation claw 17 to gradually move downward to contact the material on the cloth plate 81. At this time, the hinge point of the first connecting rod 14 and the second connecting rod 15 is below the center point of the second pulley 32, and the hinge point and the center point are on the same vertical line. At this time, the second pulley 32 continues to rotate, driving the separation claw 17 to comb and disperse the material, and the movement process is from bottom to top, from close to the sorting mechanism to away from the sorting mechanism, combing and dispersing along the inclination angle of the cloth plate 81. After combing, the support frame 4 and the separation claw 17 continue to move until they return to the starting point.

[0041] The rotation of the dual-axis motor 22 drives the screw 48 to rotate, thereby driving the nut 49 to move away from or close to the motor housing 40, stretching or retracting the adjustment frame, and the adjustment frame drives the fixed block 47 to move, thereby driving the separation claws 17 to move, so that the distance between the separation claws 17 becomes larger or smaller. The technicians can adjust the distance between the separation claws 17 according to actual needs.

[0042] As another solution, the technician can adjust the rotation speed of the first motor 20 and the dual-axis motor 22 so that the hinge point of the first connecting rod 14 and the second connecting rod 15 is below the center point of the second pulley 32, and when the hinge point and the center point are on the same vertical line, the distance between the separation claws 17 is minimum, and when the separation claws 17 comb the material, the distance between the separation claws 17 gradually increases. The two movement processes are combined, so that the separation claws 17 disperse the accumulated material in a fan shape, further improving the combing and dispersing effect of the material.

[0043] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, those skilled in the art may make various corresponding changes and modifications based on the present invention, but these corresponding changes and modifications should all fall within the scope of protection of the claims attached to the present invention.
