Description

Technical Field

[0001] The utility model relates to the technical field of recycling, crushing and separating, in particular to a waste electronic component recycling, crushing and separating device. Background Art

[0002] Waste electronic components refer to electronic components that are no longer in use or have been damaged. These components may come from the disassembly of waste electronic devices, circuit boards or other electronic products, such as: resistors, capacitors, inductors, transistors, integrated circuits, diodes, transformers, etc.

[0003] Waste electronic components generally need to be crushed and separated to recycle the metals in the electronic components and separate the crushed plastic particles for later collection and treatment to avoid environmental pollution.

[0004] The specific steps of recycling, crushing and separating waste electronic components are as follows. First, the waste electronic components need to be pretreated, including removing dangerous components such as batteries and capacitors. These components need to be treated and recycled separately. Then, the waste electronic components are put into a crushing box and crushed into particles. Next, the particulate matter is sorted and separated. First, magnetic separation is carried out to separate the magnetic metal particles, and then the non-ferrous metals can be separated by conveying them to an eddy current separator. Then, the plastic particles are conveyed to a storage box and will be granulated by a granulator into plastic particles of a certain specification and shape for recycling and reuse later.

[0005] At present, for the existing waste electronic component recycling, crushing and separating device, the sorting and separation of magnetic metal particles generally directly inserts an electromagnet into a pile of crushed particles on the conveyor belt to sort and separate the magnetic metal particles. This method has low efficiency and is prone to the omission of magnetic metal particles, reducing the anti-omission property of the electromagnet on the waste electronic component recycling, crushing and separating device for sorting and separating magnetic metal particles.

Detailed Embodiment

[0028] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0029] Referring to Figures 1-6 , a waste electronic component recycling, crushing and separating device, including a workbench 1, a crushing box 11 and a feeding group 2 are arranged on the workbench 1, a discharge pipe 12 is arranged on the crushing box 11, a feeding motor 21 and a feeding belt 22 are arranged on the feeding group 2, a first storage box 13 and a second storage box 14 are arranged on the workbench 1, and a sliding guide opening 10 is opened on the workbench 1;

[0030] A guide sliding seat 5 is slidably clamped inside a guide sliding opening 10. A horizontal air cylinder 4 and a controller 3 are arranged on a workbench 1. A time relay 31 is arranged on the controller 3. A slide rail groove 51 and a rotating motor 6 are arranged on the guide sliding seat 5. A vertical air cylinder 61 is arranged on the rotating motor 6. A connecting plate 62 is arranged on the vertical air cylinder 61. An electromagnet 7 is arranged on the connecting plate 62;

[0031] A baffle strip 23 is arranged on a conveyor belt 22. An arc-shaped inverted surface 71 is formed on the electromagnet 7. The time relay 31, the feeding group 2, and the crushing box 11 are prior arts.

[0032] A PLC is preset in the controller 3.

[0033] The guide sliding seat 5 is slidably clamped with the guide sliding opening 10 through the slide rail groove 51. The side cross-section of the guide sliding seat 5 is of an I-shaped structure to prevent the guide sliding seat 5 from slipping out of the guide sliding opening 10.

[0034] A connecting block 41 is arranged on the piston rod of the horizontal air cylinder 4. The connecting block 41 is fixedly arranged with the guide sliding seat 5. The horizontal air cylinder 4 is a long-rod reciprocating air cylinder.

[0035] A first storage bin 13 is arranged at the front end of the rotating motor 6. The vertical central axis of the rotating motor 6 is longitudinally aligned with the vertical central axis of the first storage bin 13. When the electromagnet 7 horizontally rotates 180 degrees and stops, at this time, the electromagnet 7 will be vertically aligned with the first storage bin 13 below.

[0036] A second storage bin 14 is arranged on the right side of the conveyor belt 22. The upper end surface of the second storage bin 14 is lower than the lower end surface of the conveyor belt 22. Through gravity, it is ensured that the electronic component particles without magnetic metal particles continue to be conveyed to the right and finally fall into the second storage bin 14.

[0037] The electromagnet 7 is of an overall cuboid structure. The arc-shaped inverted surface 71 is arranged at the lower corner of the electromagnet 7. The electromagnet 7 is a common electromagnet, matching a power adapter, which is a prior art.

[0038] The baffle strips 23 are two symmetrical ones and are respectively arranged on the side wall surfaces of the conveyor belt 22. The longitudinal dimension of the top view of the electromagnet 7 is the same as the distance dimension between the two baffle strips 23. Combining with the arc-shaped inverted surface 71, the electromagnet 7 can be vertically and smoothly inserted into the waste electronic component particles between the symmetrical baffle strips 23.

[0039] The baffle strip 23 is made of polyurethane rubber material, and the body is wear-resistant and has high toughness.

[0040] Working mode: A certain amount of waste electronic components are put into the crushing box 11, crushed into waste electronic component particles by the preset crushing rollers in the crushing box 11, and then fall on the conveyor belt 22 through a discharge pipe 12;

[0041] Next, when starting the controller 3, the PLC in the controller 3 will control the start of the feeding motor 21. The feeding belt 22 will drive the batch of electronic component particles to be conveyed to the right. When they are conveyed below the electromagnet 7, the PLC in the controller 3 will control the stop of the feeding motor 21, and then control the start of the horizontal cylinder 4 and the vertical cylinder 61. The vertical cylinder 61 will drive the electromagnet 7 to insert into the electronic component particles and perform vertical reciprocating movement according to a certain reciprocating distance. At the same time, the horizontal cylinder 4 will drive the guide slide 5 to perform horizontal reciprocating sliding along the guide slide 10 according to a certain reciprocating distance, thereby driving the electromagnet 7 to perform horizontal reciprocating movement in the electronic component particles, realizing horizontal reciprocating translation while performing vertical reciprocating movement and comprehensively magnetically adsorbing and separating the magnetic metal particles in the electronic component particles. And this method will stop after running for a period of time according to the time preset on the time relay 31 to avoid omission, improving the anti-omission property of the electromagnet 7 on the waste electronic component recycling and crushing separation device for sorting and separating magnetic metal particles;

[0042] After comprehensively magnetically adsorbing and separating the magnetic metal particles in the batch of electronic component particles, the PLC in the controller 3 will control the stop of the horizontal cylinder 4 and control the vertical cylinder 61 to drive the electromagnet 7 to move upward to reset. Then the PLC in the controller 3 will control the start of the rotating motor 6 to drive the electromagnet 7 to rotate horizontally by 180 degrees and stop. Then the PLC in the controller 3 will cut off the power supply to the electromagnet 7. Due to gravity, all the magnetic metal particles adsorbed on the surface of the electromagnet 7 will fall into the first storage bin 13. Later, the PLC in the controller 3 will control the start of the feeding belt 22 to continue conveying the electronic component particles without magnetic metal particles to the right and finally fall into the second storage bin 14;

[0043] Finally, the electronic component particles stored in the second storage bin 14 will be moved to an eddy current separator to separate non-ferrous metals (which is the prior art).

[0044] Moreover, when the electromagnet 7 is inserted downward into the electronic component particles, by setting an arc-shaped chamfer 71 structure at the lower corner of the electromagnet 7, the electromagnet 7 can be smoothly inserted vertically into the waste electronic component particles between the symmetrical baffle strips 23.

[0045] In addition, by symmetrically arranging baffle strips 23 on the side of the feeding belt 22, it is possible to prevent the particles from slipping during the process of magnetically adsorbing and separating the magnetic metal particles in the waste electronic component particles.

[0046] The above are only the preferred specific embodiments of the present utility model, but the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered within the protection scope of the present utility model.
