Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and in particular to a continuous sorting device for non-ferrous metal waste particles. Background Art

[0002] As an efficient sorting device for non-ferrous metal waste particles, the eddy current separator has been widely used in industries such as electronic waste recycling and non-ferrous metal regeneration due to its excellent sorting effect, strong adaptability, and reliable mechanical structure.

[0003] However, in the traditional all-magnetic permanent magnet drum type eddy current separator, magnetic substances during the working process will be forcibly adsorbed on the magnetic drum by the magnetic field and are difficult to be effectively discharged. The accumulated magnetic substances will not only cause the drum skin to wear rapidly, increase the equipment failure rate and maintenance cost, but also easily form a magnetic short circuit, affecting the effective sorting of non-ferrous metals.

[0004] For example, in an efficient sorting device for fine-grained waste non-ferrous metals with the publication number CN210614014U in the prior art, before the eddy current sorting of non-ferrous metals, fine-grained magnetic materials are sucked out through a magnetic adsorption mechanism and automatically discharged. Although it can avoid the problem that a large amount of magnetic substances accumulate on the surface of the eddy current drum and are difficult to discharge, affecting the sorting of non-ferrous metals;

[0005] However, during the sorting of magnetic substances, only a small range of adsorption treatment is carried out by means of magnetic rods on the conveyor drum at the moment of discharging on the conveyor belt. When non-ferrous metals are discharged, the adsorbed magnetic substances will be impacted simultaneously. It is still difficult to maintain the effective adsorption treatment of some magnetic substances, and it is impossible to avoid the aggregated accumulation of magnetic substances through multiple adsorption methods to prevent the premature separation and discharge of magnetic substances, resulting in incomplete sorting.

[0013] Preferably, the fixed shell is fixedly connected to the auxiliary rotating belt through a connecting frame, both ends of the rotating shaft pass through the outside of the fixed shell and are fixedly installed with gears, and toothed plates matching the gears are fixedly connected on the inner walls of both sides of the sorting box and located between the upper mounting seat and the lower mounting seat.

[0014] Preferably, a movable frame with a U-shaped structure is slidably mounted on the opening side of the fixed shell and on one side of the discharge pipe, a cam plate slidably matched with the movable frame is fixedly connected to one side of the gear, and a plurality of combing rods are equidistantly mounted on the movable frame.

[0015] Preferably, the protrusion on the cam plate on one side corresponds to the recessed portion on the cam plate on the other side.

[0017] The beneficial effects of the present invention are as follows:

[0018] (1) In the present invention, first, through the material control roller in the feed pipe, intermittent feeding treatment of non-ferrous metal waste particles is achieved to eliminate the problem that the too-thick flat laying of materials affects the sorting effect.

[0036] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0037] Embodiment 1: Please refer to Figures 1 - 10 As shown, for the problem that when non-ferrous metals are discharged in the prior art, the adsorbed magnetic substances will be impacted synchronously, it is still difficult to maintain the effective adsorption of some magnetic substances, and it is impossible to avoid the premature separation and discharge of magnetic substances through multiple adsorption methods, resulting in incomplete sorting, the following solutions can be adopted;

[0038] In this embodiment, a continuous sorting device for non-ferrous metal waste particles includes a sorting box 1 and an eddy current separator 11. Inside the sorting box 1, a main rotating belt 12 and a secondary rotating belt 13 are installed. A number of magnetic rods are embedded inside both the main rotating belt 12 and the secondary rotating belt 13. The magnetic rods on the main rotating belt 12 are equidistantly installed along its length direction. The magnetic rods on the secondary rotating belt 13 are equidistantly arranged between adjacent two turning and spreading components 2 to facilitate the subsequent cleaning of magnetic substances. A plurality of turning and spreading components 2 are installed on the secondary rotating belt 13;

[0039] The main rotating belt 12 drives a number of material piles to move towards the eddy current separator 11. The secondary rotating belt 13 drives a plurality of turning and spreading components 2 to move in the opposite direction between the upper mounting seat 15 and the lower mounting seat 14, so that during the material conveying process, the material is leveled, turned over and spread, and reciprocally pushed for multiple times, improving the sorting effect of the magnetic substances in the material by the main rotating belt 12. The length of the secondary rotating belt 13 is less than that of the main rotating belt 12 to avoid affecting the feeding, magnetic substance sorting and discharging of non-ferrous metal waste particles;

[0040] The turning and spreading component 2 includes a fixed housing 21. Inside the fixed housing 21, a rotating shaft 22 is rotatably installed. A number of turning plates 23 are fixedly connected to the rotating shaft 22. One side of the fixed housing 21 is fixedly communicated with a discharge pipe 24. The rotating shaft 22 drives the plurality of turning plates 23 to rotate. The turning plates 23 in rotation level the material pile moving below the fixed housing 21 on the main rotating belt 12, and drive the excess material to move along the inner wall of the fixed housing 21, and then are discharged and lifted through the discharge pipe 24 to contact the secondary rotating belt 13;

[0041] The magnetic rods inside the secondary rotating belt 13 sort and adsorb the magnetic substances in the lifted material. The lifted and sorted material falls back onto the main rotating belt 12 for leveling treatment again. The magnetic rods inside the main rotating belt 12 sort and adsorb the magnetic substances in the leveled material and the falling material. Through the movement of the plurality of turning and spreading components 2 on the main rotating belt 12 and in combination with the secondary rotating belt 13, multiple sorting and adsorption are carried out.

[0042] Inside the sorting box 1, a lower mounting seat 14 adapted to the corresponding main rotating belt 12 and an upper mounting seat 15 adapted to the corresponding secondary rotating belt 13 are fixedly connected. The provided upper mounting seat 15 and lower mounting seat 14 are not only used for the installation of the corresponding rotating belts, but also ensure the stability during the conveying process of the rotating belts. Rotating rollers 16 are rotatably connected to both sides of the upper mounting seat 15 and the lower mounting seat 14. A number of tooth blocks are provided on the outer circumferential wall of the rotating rollers 16, and adapted tooth grooves are provided on the rotating belts for anti-slip rotation of the rotating belts;

[0043] The rotating rollers 16 of the upper mounting base 15 and the lower mounting base 14 are both driven by an external servo motor. By driving the rotating rollers 16 on the upper mounting base 15 and the lower mounting base 14 with the external servo motor, the main rotating belt 12 and the auxiliary rotating belt 13 are driven to rotate, and the rotation speed of the auxiliary rotating belt 13 is greater than that of the main rotating belt 12, thereby improving the spreading and lifting effects on the material.

[0044] A second discharge pipe 17 is fixedly connected to the bottom of the sorting box 1, and a first discharge pipe 18 is provided which cooperates with the eddy current separator 11. The non-ferrous metal waste particles after multiple sorts are discharged through the first discharge pipe 18 driven by the main rotating belt 12 and enter the eddy current separator 11 for sorting treatment of the non-ferrous metal waste particles. A diagonal scraping plate 19 which slides with the main rotating belt 12 is fixedly connected to the top of the second discharge pipe 17. The magnetic substances adsorbed on the main rotating belt 12 move above the second discharge pipe 17 as the main rotating belt 12 rotates, and the magnetic substances on the main rotating belt 12 are cleaned by combining with the diagonal scraping plate 19.

[0045] A storage hopper 110 is provided on one side of the top of the sorting box 1, and a feed pipe 111 which penetrates into the interior of the sorting box 1 is fixedly connected to the bottom of the storage hopper 110. The bottom of the feed pipe 111 slides with the main rotating belt 12, and a notch is provided on the side of the bottom of the feed pipe 111 close to the auxiliary rotating belt 13 for accurately discharging the material in the feed pipe 111 onto the main rotating belt 12 to avoid the problem of the material falling from the other side of the main rotating belt 12.

[0046] A control material roller 112 is rotatably installed in the feed pipe 111 through a rotating rod, and control material grooves are provided on the circumferential side wall of the control material roller 112. Through the control material roller 112 in the feed pipe 111, intermittent feeding treatment of the non-ferrous metal waste particles is realized to eliminate the problem that the over-thick spreading of the material affects the sorting effect. The non-ferrous metal waste particles to be screened are placed in the storage hopper 110, the material received by the storage hopper 110 enters the feed pipe 111, and part of the material is placed in the control material grooves in the control material roller 112.

[0047] Sprockets are installed on both the roller shaft of the rotating roller 16 on one side of the lower mounting base 14 and the rotating rod, and the sprockets are connected by a chain drive. By the rotation of the rotating roller 16 on the lower mounting base 14, the control material roller 112 is driven to rotate by combining the sprockets and the chain, so that the opening of the control material groove faces downward, and the material is put on one side of the main rotating belt 12, and then through the continuous rotation of the control material roller 112, the purpose of intermittent feeding is realized.

[0048] The fixed housing 21 is fixedly connected to the auxiliary rotating belt 13 through a connecting frame 25. The connecting frame 25 is connected to the auxiliary rotating belt 13 by a plurality of bolts arranged in a single row, and auxiliary seats which are in contact with the auxiliary rotating belt 13 are fixedly connected to both sides of the connecting frame 25 for realizing the stability of the fixed housing 21 during movement.

[0049] Both ends of the rotating shaft 22 penetrate to the outside of the fixed housing 21 and are fixedly installed with gears 26. On both inner walls of the sorting box 1 and located between the upper mounting seat 15 and the lower mounting seat 14, there is fixedly connected a toothed plate 113 adapted to the gear 26. During the movement, the gears 26 on both sides of the fixed housing 21 are engaged with the corresponding toothed plates 113, causing the rotating shaft 22 to drive a plurality of turning plates 23 to rotate.

[0050] On the opening side of the fixed housing 21 and on one side of the discharge pipe 24, a U-shaped movable frame 27 is slidably installed. One side of the gear 26 is fixedly connected with a cam disk 28 that is slidably matched with the movable frame 27. A number of comb rods 29 are equidistantly installed on the movable frame 27. By means of the gear 26 driving the cam disk 28 to rotate, the movable frame 27 is further caused to reciprocate. Combining the contact between the comb rods 29 on the movable frame 27 and the main rotating belt 12, the flattened material is subjected to reciprocating pusher treatment, improving the sorting and adsorption effect of the magnetic rods in the main rotating belt 12 on the magnetic substances in the flattened material.

[0051] The convex part on one side of the cam disk 28 corresponds to the concave part on the other side of the cam disk 28, so that when the two cam disks 28 rotate, the movable frame 27 can be pushed to move through the convex part on one side of each of them, thus avoiding the problem of motion interference.

[0052] Embodiment 2: Please refer to Figure 1 、 Figure 2 and Figure 11 As shown in, for the problem that the magnetic substances on the auxiliary rotating belt are not easy to clean, the following solution can be adopted;

[0053] In this embodiment, a follow-up type scraping component 3 is arranged on the sorting box 1 and above the auxiliary rotating belt 13. The follow-up type scraping component 3 includes a moving seat 31. A slider 32 is slidably connected inside the moving seat 31, and a spring 33 is fixedly connected between one side of the slider 32 and the moving seat 31. The bottom of the slider 32 is fixedly connected with a T-shaped scraping plate 34 that slides on the auxiliary rotating belt 13;

[0054] A plurality of turning and flattening components 2 are driven by the auxiliary rotating belt 13 to move to the top of the upper mounting seat 15. When the T-shaped scraping plate 34 is located between two groups of turning and flattening components 2, the T-shaped scraping plate 34 is caused to move between the two groups of turning and flattening components 2 to clean the sorted and adsorbed magnetic substances on the auxiliary rotating belt 13. During the movement of the T-shaped scraping plate 34, the turning and flattening components 2 continue to move, thereby driving the T-shaped scraping plate 34 to drive the slider 32 to move synchronously inside the moving seat 31 and compress the spring 33, achieving the purpose of multi-directional movement, realizing both the cleaning of the magnetic substances on the auxiliary rotating belt 13 and avoiding interference with the rotation of the auxiliary rotating belt 13, achieving the effect of continuous sorting and cleaning, ensuring the sorting efficiency while improving the sorting quality.

[0055] On both sides of the sorting box 1, mounting shells 35 are symmetrically and fixedly connected and communicated. The bottom of the mounting shell 35 is fixedly connected with a material guiding hopper 36. Between the mounting shells 35, a guide rod that slides with the moving seat 31 is fixedly connected, and a reciprocating lead screw 37 that is threadedly connected with the moving seat 31 is rotatably installed. A servo motor for driving the reciprocating lead screw 37 to rotate is fixedly installed on the mounting shell 35;

[0056] The servo motor drives the reciprocating lead screw 37 to rotate. The reciprocating lead screw 37, in combination with the guide rod, causes the moving seat 31 to move, resulting in the T-shaped scraping plate 34 moving between the two turning and spreading components 2. During the process of the T-shaped scraping plate 34 moving to clean the magnetic substances on the auxiliary turning belt 13, the magnetic substances are pushed to one side of the mounting shell 35 and then discharged through the corresponding material guiding hopper 36. After the T-shaped scraping plate 34 moves to separate from the mounting shell 35 and the turning and spreading component 2, under the compression of the spring 33, the slider 32 drives the T-shaped scraping plate 34 to reset, reciprocally driving the moving seat 31 to move in the reverse direction, and again pushing and cleaning the sorted and adsorbed magnetic substances on the auxiliary turning belt 13 and discharging them through the mounting shell 35 and the material guiding hopper 36 on the other side.

[0057] Embodiment Three: Please refer to Figures 1 - 11 As shown, the present invention also proposes a method for using a continuous sorting device for non-ferrous metal waste particles, including the following steps:

[0058] Step 1: Place the non-ferrous metal waste particles to be screened into the storage hopper 110. The materials received by the storage hopper 110 enter the feeding pipe 111, and part of the materials are placed in the control grooves in the control roller 112. The rotating rollers 16 on the upper mounting seat 15 and the lower mounting seat 14 are driven to rotate by an external servo motor, causing the main turning belt 12 and the auxiliary turning belt 13 to rotate. The rotation speed of the auxiliary turning belt 13 is greater than that of the main turning belt 12. Through the rotation of the rotating roller 16 on the lower mounting seat 14, the control roller 112 is driven to rotate by the sprocket and the chain, causing the opening of the control groove to face downward, and intermittently discharging the materials to one side of the main turning belt 12;

[0059] Step 2: The main turning belt 12 drives a plurality of material piles to move towards the eddy current separator 11. The auxiliary turning belt 13 drives a plurality of turning and spreading components 2 to move in the reverse direction between the upper mounting seat 15 and the lower mounting seat 14. During the movement, the gears 26 on both sides of the fixed housing 21 are engaged with the corresponding toothed plates 113, causing the rotating shaft 22 to drive a plurality of turning plates 23 to rotate. The turning plates 23 in rotation scrape and level the material piles moving below the fixed housing 21 on the main turning belt 12;

[0060] It drives the surplus materials to move along the inner wall of the fixed housing 21, and then discharges and raises them through the discharge pipe 24. The materials come into contact with the secondary rotating belt 13. The magnetic rods inside the secondary rotating belt 13 are used to sort and adsorb the magnetic substances in the raised materials. The sorted and raised materials fall onto the main rotating belt 12 again for leveling treatment. The magnetic rods inside the main rotating belt 12 are used to sort and adsorb the magnetic substances in the leveled materials and the falling materials. Through the movement of multiple turning and leveling components 2 on the main rotating belt 12 and in combination with the secondary rotating belt 13, multiple sorting and adsorption operations are carried out.

[0061] Step 3: The gear 26 drives the cam disk 28 to rotate, thereby causing the movable frame 27 to reciprocate. In combination with the contact between the comb rod 29 on the movable frame 27 and the main rotating belt 12, the leveled materials are reciprocally pushed, improving the sorting and adsorption effect of the magnetic rods in the main rotating belt 12 on the magnetic substances in the leveled materials. The non-ferrous metal waste particles after multiple sorts are discharged through the first discharge pipe 18 driven by the main rotating belt 12 and enter the eddy current separator 11 for sorting treatment of the non-ferrous metal waste particles. The magnetic substances adsorbed on the main rotating belt 12 move above the second discharge pipe 17 as the main rotating belt 12 rotates. In combination with the inclined scraping plate 19, the magnetic substances on the main rotating belt 12 are cleaned.

[0062] Step 4: Multiple turning and leveling components 2 are driven by the secondary rotating belt 13 to move to the top of the upper mounting seat 15. When the T-shaped scraping plate 34 is located between two groups of turning and leveling components 2, the servo motor drives the reciprocating lead screw 37 to rotate. The reciprocating lead screw 37, in combination with the guide rod, causes the moving seat 31 to move, resulting in the T-shaped scraping plate 34 moving between the two groups of turning and leveling components 2 to clean the sorted and adsorbed magnetic substances on the secondary rotating belt 13 and push the magnetic substances to the mounting shell 35 on one side, and then discharge them through the corresponding guide hopper 36.

[0063] During the movement of the T-shaped scraping plate 34, the turning and leveling components 2 continue to move, thereby driving the T-shaped scraping plate 34 to carry the slider 32 to move synchronously inside the moving seat 31 and compress the spring 33. After the T-shaped scraping plate 34 moves to separate from the mounting shell 35 and the turning and leveling components 2, under the compression of the spring 33, the slider 32 is caused to carry the T-shaped scraping plate 34 to reset, reciprocally driving the moving seat 31 to move in the reverse direction, and again pushing and cleaning the sorted and adsorbed magnetic substances on the secondary rotating belt 13 and discharging them through the mounting shell 35 and the guide hopper 36 on the other side.

[0064] The above is only the preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and all should be covered within the protection scope of the present invention.
