Description

Technical Field

[0001] This utility model relates to the field of eddy current separator technology, and in particular to an eddy current separator. Background Technology

[0002] Eddy current separators are a useful method for recycling non-ferrous metals. They can separate some non-ferrous metals from electronic waste. Eddy current separators are mainly used in electronic waste recycling production lines to separate non-ferrous metals such as copper and aluminum from the mixed materials. They can also be used for environmental protection and are widely used in the non-ferrous metal recycling industry.

[0003] Chinese patent CN208612751U discloses an eddy current separator that uses vibration to evenly distribute waste fragments in the feed box onto the separating belt. Conductive metals are pushed to the side when passing through the magnetic plate and are initially separated from the waste. The vibration generated by the vibrating component improves the separation efficiency.

[0004] 1. This eddy current separator can only improve the separation efficiency. However, in actual use, the material to be separated is transported by a conveyor belt so that it can be separated. This makes it easy for the material to accumulate, which makes it difficult for the eddy current separator to separate the material and thus affects the separation effect of the eddy current separator.

[0005] 2. Furthermore, when the material falls into the conveyor belt, it is easy for the material to slide off from both sides of the conveyor belt as it is conveyed, resulting in a large amount of material falling to the ground. This is not conducive to the sorting work and requires a waste of manpower and resources to clean up the fallen material, thus affecting the sorting efficiency of the eddy current separator.

[0006] Therefore, an eddy current separator is proposed. Utility Model Content

[0012] Preferably, a reset spring is connected between the first shunt block and the second shunt block, with the first shunt block connected to one side of the reset spring and the second shunt block connected to the other side of the reset spring.

[0013] Preferably, a dividing chamber is placed on the upper surface of the main body of the eddy current separator, and a partition is fixedly connected to the upper surface inside the dividing chamber.

[0014] Preferably, two U-shaped plates are fixedly installed on the upper end face of the eddy current separator body.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1 to 4This utility model provides a technical solution: an eddy current separator, including an eddy current separator body 1 and a vibrating feeder 2. Two side plates 3 are installed on the upper end face of the eddy current separator body 1. Conveyor belts 4 are installed on the inner ends of the two side plates 3. U-shaped frames 5 are fixedly connected to the inner ends of the two side plates 3. Rotating rods 6 and five cam rods 7 are rotatably connected to the rear end face of the U-shaped frame 5. Through the installation and use of the rotating rods 6 and cam rods 7, the rotating rods 6 and cam rods 7 can be rotated and adjusted together by the transmission action of the belt. As the cam rods 7 squeeze the diverting blocks, the position of the diverting blocks is changed, so as to adjust the spacing between the diverting blocks. Two connecting rods 11 are fixedly installed on the inner ends of the U-shaped frame 5. The outer surfaces of the two connecting rods 11 are respectively sliding... The conveyor belt 4 is dynamically connected to a first diverting block 12 and a second diverting block 13. Through the diverting of the five diverting blocks, the accumulated material can be spread more evenly on the conveyor belt 4. The inner ends of the two side plates 3 are rotatably connected to a reciprocating threaded rod 14. The outer surface of the reciprocating threaded rod 14 has two curved plates 17. The front end of the curved plate 17 is equipped with a limit baffle 18. Through the installation and use of the curved plate 17 and the limit baffle 18, the distance between the curved plate 17 is adjusted synchronously with the rotation of the reciprocating threaded rod 14, so that the limit baffle 18 can flexibly limit materials of different specifications. When the material is larger, the distance between the diverting blocks will also be increased, and the distance between the limit baffles 18 will also be increased, so as to ensure stable material conveying.

[0028] A magnetic core cylinder 21 is installed on the right end face of the U-shaped frame 5. One side of the rotating rod 6 and the cam rod 7 respectively penetrate the U-shaped frame 5 and extend to the front end face of the U-shaped frame 5. The outer surface of the rotating rod 6 is fixedly connected to the first pulley 8, the outer surface of the cam rod 7 is fixedly connected to the second pulley 9, the rear end face of the rotating rod 6 is fixedly connected to the servo motor 10, the front end face of the rotating rod 6 is connected to the first bevel gear 15, the outer surface of the reciprocating threaded rod 14 is connected to the second bevel gear 16, and the inner ends of the two side plates 3 are fixedly connected to two limiting rods 19. By setting the limiting rods 19, the limiting rods 19 are used to limit the movement direction of the bent plate 17, so that the bent plate 17 remains unchanged while driving the limiting baffle 18 to move. The two limiting rods 19 are designed to be parallel to each other.

[0029] A return spring 20 connects the first diverting block 12 and the second diverting block 13. The return spring 20 connects the five diverting blocks sequentially for synchronized spacing adjustment. When the cam rod 7 rotates to a certain position without pressing the diverting blocks, the return spring 20's elasticity returns the diverting blocks to their original positions. At this point, the spacing between the diverting blocks is minimal, suitable for sorting smaller materials, allowing for uniform material conveying and sorting. One side of the return spring 20 is connected to the first diverting block 12, and the other side is connected to the second diverting block 13. A dividing chamber 22 is placed on the upper surface of the eddy current separator body 1. The upper part of the dividing chamber 22... A partition 23 is fixedly connected to the end face. Through the installation and use of the partition 23 and the dividing chamber 22, the partition 23 divides the dividing chamber 22 into two parts. The side closer to the conveyor belt 4 is the place to store waste materials, while the side away from the conveyor belt 4 is the place to store the sorted materials. Two U-shaped plates 24 are fixedly installed on the upper end face of the eddy current separator body 1. The two ends of the inner side of the two U-shaped plates 24 are connected to the crossbars 25. The outer surface of the crossbars 25 is provided with a support plate 26. The front end face of the support plate 26 is provided with a sliding hole 28. The sliding hole 28 is adapted to the crossbars 25. The outer surface of the crossbars 25 is slidably connected to the front end face of the support plate 26 through the sliding hole 28. A splash guard 27 is installed on the left end face of the support plate 26.

[0030] Working Principle: When the eddy current separator is in use, starting the servo motor 10 causes the output shaft of the servo motor 10 to drive the rotating rod 6 to rotate. Simultaneously, the belts are sequentially adjusted on the pulleys of the rotating rod 6 and the cam rods 7. This allows the rotating rod 6 to drive the five cam rods 7 to rotate and adjust together. The cam rods 7 then slowly rotate, sequentially pressing the first diverting block 12 and the second diverting block 13. This allows the six diverting blocks, connected to the return spring 20, to synchronously adjust their spacing on the two sets of connecting rods 11. When material is conveyed by the conveyor belt 4, it is diverted by the diverting blocks, allowing the material to be evenly distributed on the conveyor belt 4, thus avoiding accumulation on the conveyor belt 4. This facilitates the eddy current separator's material sorting operation. Furthermore, the spacing between the diverting blocks can be flexibly adjusted to improve the eddy current separation efficiency for materials of different specifications. The sorting effect of the flow separator is achieved through the meshing of bevel gear 15 and bevel gear 16. The meshing method is bevel gear meshing, which allows the rotating rod 6, which is equipped with bevel gear 16, to rotate and adjust the reciprocating threaded rod 14, which is also equipped with bevel gear 16. This allows the two sets of curved plates 17 of the screw drive to move inward or outward simultaneously, so that the limiting baffles 18 at the curved plates 17 can flexibly limit the conveyed material, preventing the material from slipping off the sides of the conveyor belt 4 and ensuring the safe operation of the sorting work. At the same time, the support plate 26 can slide and adjust its position on the crossbar 25, so that the support plate 26 can move the splash guard 27 to the dividing bin 22 and the conveyor belt 4. The splash guard 27 can block the sorted material, allowing the material to fall accurately into the dividing bin 22 and preventing the sorted material from easily splashing onto the ground.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
