[0002] The separation and recycling of metal-containing plastics is an important waste treatment technology. Its main purpose is to separate metals from plastics so that they can be recycled and reused separately. This recycling technology not only helps to reduce resource waste, but also reduces environmental pollution and promotes a circular economy. The separated metals can usually be reprocessed by smelting and other methods to make new products. This helps to save mineral resources and reduce energy consumption. The recycled plastics can be reused by compression, cutting, reprocessing, etc., such as making plastic particles and plastic products. The existing separation is mostly to crush the metal-containing plastic waste and then separate the metal particles from the plastic particles by screening. Vibration equipment is used to separate the metal and plastic according to their movement characteristics in vibration.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] See also Figures 1 - 13 The present invention provides a technical solution: a physical separation and recovery device for metal-containing plastics, comprising a pulverizer 1, a pulverizing roller 20 is rotatably connected inside the pulverizer 1, a sieve plate 21 is fixedly connected inside the pulverizer 1 and below the pulverizing roller 20, a sorting box 36 is fixedly connected to one side of the pulverizer 1, a grounding roller 31 drivingly connected to the pulverizing roller 20 is fixedly connected inside the sorting box 36 for compensating and stabilizing the electric field, a high-voltage electrode 32 is fixedly connected to one side of the grounding roller 31 for generating a high-voltage electrostatic field, and the bottom of the pulverizer 1 is connected to the sorting box 36 through a feeding part.

[0031] It should be noted that a controller and a corresponding operation panel are provided in this embodiment. Under the action of the belt conveyor, the material slowly enters the pulverizer 1, and the pulverizing roller 20 is driven by the motor and the belt drive to rotate inside the pulverizer 1. The plastic with metal is impacted and crushed with the metal plate on the inner wall under the action of the pulverizing roller 20. The crushed material falls into the feeding part below through the screen plate 21. The feeding part conveys the crushed material to the outside of the grounded roller 31, and a high-voltage electric field is generated through the high-voltage electrode 32. Under the action of the electric field force, the conductive and non-conductive substances in the material will move along different trajectories due to different electrical properties. The electric field is applied to the material through the high-voltage electrode to form a strong electric field area. In the electric field, because the conductive material can accumulate electric charge, it is driven by a large electrostatic force (Coulomb force) under the action of the electric field and moves in the opposite direction of the electrode. Non-conductive materials cannot accumulate enough electric charge, so the electrostatic force they are subjected to is small, and their movement trajectory in the electric field is relatively gentle. The electrostatic force on conductive materials and non-conductive materials is different, and their movement trajectories are also different. Due to the action of the electric field force, conductive materials will be attracted by the high-voltage electrodes of the electric field, while non-conductive materials are relatively less affected, thereby separating and recovering them.

[0032] In one embodiment, Figure 8 As shown, a plurality of discharge troughs 34 for collecting materials are provided inside the sorting box 36 and below the grounding roller 31. A brush is fixed inside the sorting box 36 and on the side away from the high-voltage electrode 32. The brush is slidably connected to the grounding roller 31 for cleaning plastic particles.

[0033] It should be noted that in this embodiment, the electric field is formed between the high-voltage electrode and the grounded roller. The high-voltage electrode provides positive charge, and the grounded roller is in a grounded state. The conductive material (such as metal) will generate corresponding charge due to the voltage difference between the electrode and the conductive material. The accumulated charge of the conductive material is opposite to the direction of the electric field, causing the metal material to move toward the other pole of the electric field (i.e., away from the grounded roller). The corresponding discharge trough 34 is set according to its landing trajectory to sort and collect it. When the material passes through the grounded roller 31, the plastic side rotates to the bottom with the grounded roller 31 and is brought to the receiving position below by centrifugal force. In addition, the brush cleans the outside of the grounded roller 31 to prevent the plastic particles from reciprocating with the grounded roller 31.

[0034] In one embodiment, Figure 1 , 2, as shown in Figures 3, 4, 5, 6, 7, and 8, it further includes a feeding mechanism. The feeding mechanism includes a feeding box 2 fixedly connected to the feeding port of the crusher 1. The feeding port of the crusher 1 is fixedly connected with a feeding box 7. The feeding box 7 is communicated with the feeding box 2. A cylinder 37 is fixedly connected to one side of the feeding box 7. A feeding frame 5 is slidably arranged inside the feeding box 2. The output end of the cylinder 37 is fixedly connected to the feeding box 7. A partition plate 6 with an inverted L-shaped structure is fixedly connected to the top of the feeding frame 5 for blocking materials and forming an impact area. An impact crushing part is arranged above the partition plate 6. A receiving top plate 4 is slidably connected inside the feeding box 2. A driving part for driving the receiving top plate 4 to lift and lower is arranged at the bottom of the receiving top plate 4. When the feeding frame 5 is located inside the feeding box 2, the partition plate 6 blocks the feeding box 2, and an impact area is formed at the top of the partition plate 6. When the feeding frame 5 is located at the top of the feeding port of the crusher 1, the feeding frame 5 pushes the materials inside the receiving top plate 4 into the crusher 1, and the partition plate 6 slides out of the inside of the feeding box 2. The materials at the top of the feeding box 2 fall onto the top of the receiving top plate 4. The driving part includes a reciprocating lead screw 16 rotatably installed on one side of the feeding box 2. A motor two 17 for driving the reciprocating lead screw 16 to rotate is installed at the bottom of the reciprocating lead screw 16. A metal plate is threaded on the outside of the reciprocating lead screw 16. One end of the top of the metal plate is fixedly connected with a lifting rod 3. The lifting rod 3 is fixedly connected with the receiving top plate 4. The lifting rod 3 is slidably connected with the feeding box 2.

[0035] It should be noted that in this embodiment, a travel switch is arranged at the bottom of the feeding box 2. Under the action of the controller, the motor two 17 drives the reciprocating lead screw 16 to rotate. The reciprocating lead screw 16 drives the metal plate to slide on the slide bar on one side, thereby driving the lifting rod 3 to lift and lower inside the feeding box 2. When the metal plate contacts the forming switch, at this time, the receiving top plate 4 is located at the bottom of the feeding frame 5. The controller controls the cylinder 37 to drive the feeding frame 5 to move towards the inside of the feeding box 7, so as to pull the materials at the top of the receiving top plate 4 into the feeding box 7, and convey the materials into the crusher 1 through the opening at the bottom of the feeding frame 5 for crushing treatment. When the feeding frame 5 moves towards the inside of the feeding box 7, the feeding frame 5 drives the partition plate 6 to move above the feeding box 7. Under the extrusion of the inner wall of the feeding box 2, the materials after impact on the top of the partition plate 6 fall, so that the top of the feeding box 2 is in an open state. The controller controls the belt conveyor for feeding to pause feeding. The materials after impact fall onto the top of the receiving top plate 4. At this time, under the action of the reciprocating lead screw 16, the metal plate drives the lifting rod 3 and the receiving top plate 4 to move downward. Under the action of the timer, the cylinder 37 drives the feeding frame 5 to quickly reset, so as to drive the partition plate 6 to block the feeding box 2 again through the feeding frame 5, thereby forming a closed space at the bottom of the impact crushing part.

[0036] In one embodiment, as Figure 11As shown, a plurality of cleaning nozzles 19 are fixedly connected to one side of the feeding box 2, and the cleaning nozzles 19 are connected to a high-pressure water source through a solenoid valve. An air drying box 18 is arranged on one side of the feeding box 2 and above the cleaning nozzles 19. The air drying box 18 is connected to the feeding box 2, and a plurality of sets of fans are installed inside the air drying box 18, and electric heating wires are installed at the air outlets of the fans.

[0037] It should be noted that in the present embodiment, a plurality of water filtering holes are arranged on the top of the receiving top plate 4, and a drainage pipe is arranged at the bottom of the feeding box 2. When the receiving top plate 4 drives the material to move downward, under the monitoring of the infrared sensor on one side of the slide rod, when the receiving top plate 4 is located at the position of the corresponding cleaning nozzle 19, the solenoid valve is controlled to be energized, so that high-pressure water is used to perform high-pressure flushing on the top of the receiving top plate 4. When the reciprocating screw 16 drives the metal plate to move upward, the fan blows out wind, and the wind is heated by the electric heating wire, so that the workpiece on the top of the receiving top plate 4 is dried by the hot air. When the dried material drives the bottom of the feeding frame 5, it is pushed into the crusher 1 by the cylinder 37 and the feeding frame 5 for crushing.

[0038] In one embodiment, Figure 1 , 2 As shown in , 3, 5, 8, and 11, the impact and crushing part includes a plurality of fixed support plates 8 fixedly connected to one side of the top of the feeding box 2, a collision rod 9 is slidably connected to the middle of the plurality of fixed support plates 8, a lifting support plate 11 is slidably connected inside the fixed support plate 8, a roller 13 is rotatably connected to one side of the lifting support plate 11, the lifting support plate 11 is fixed to the impact rod 9, a spring 10 is sleeved on the outside of the impact rod 9 and located between the fixed support plate 8 and the lifting support plate 11, an arc-shaped toggle rod 14 for driving the roller 13 to rise is rotatably connected to the outside of the feeding box 2 corresponding to the position of the lifting support plate 11, two adjacent arc-shaped toggle rods 14 are transmission connected by a chain assembly, a motor 12 is fixedly connected to one side of the feeding box 2, and the output end of the motor 12 is transmission connected to one of the arc-shaped toggle rods 14.

[0039] It should be noted that, in the present embodiment, when the loading frame 5 drives the partition plate 6 to reset, the partition plate 6 blocks the middle of the crusher 1, and blocks the lower part of the impact rod 9 through the partition plate 6, so that the lower part of the impact rod 9 is a closed space, and the arc-shaped toggle rod 14 is composed of a disc and an arc-shaped rod, and the controller controls the motor 12 to work, and the motor 12 drives the arc-shaped toggle rod 14 located at the edge to rotate, and the rotation of the arc-shaped toggle rod 14 drives the remaining arc-shaped toggle rods 14 to rotate through the sprocket and the chain, and when the arc-shaped toggle rod 14 rotates, when the arc-shaped toggle rod 14 contacts the roller 13, the arc-shaped toggle rod 14 The roller 13 is pushed upward, and the roller 13 drives the lifting support plate 11 to move upward along the sliding hole in the middle of the fixed support plate 8. The lifting support plate 11 drives the impact rod 9 to compress the spring 10 upward. When the roller 13 is separated from the arc-shaped toggle rod 14, the lifting support plate 11 drives the impact rod 9 to impact downward under the thrust of the spring 10, and the reciprocating cycle is repeated. The impact rod 9 reciprocates to impact the material on the top of the partition plate 6, thereby achieving primary separation of large pieces of material, thereby preventing jamming and overhead in the crusher 1. The material after the impact is cleaned and dried on the receiving top plate 4 and then sent into the crusher 1 through the feeding frame 5.

[0040] In one embodiment, Figure 2 , 3 As shown in Figures 5 and 9, a fan 15 is fixedly connected to one side of the loading box 2, and the fan 15 is transmission-connected to one of the arc-shaped toggle rods 14. The air inlet of the fan 15 is connected to the feeding box 7 through an air duct, so as to discharge the dust generated by the pulverizer 1, and a dust bag is fixedly connected to the output end of the fan 15.

[0041] It should be noted that, in this embodiment, the motor 12 drives multiple arc-shaped toggle rods 14 to rotate simultaneously through the sprocket and the chain. The arc-shaped toggle rod 14 away from one end of the motor 12 drives the rotating blades inside the fan 15 to rotate to generate airflow, thereby extracting the air inside the grinder 1, so that the smoke and dust generated by the crushing are sucked into the dust collecting bag for filtration and collection, which is convenient for the centralized collection of the crushed metal debris and plastic debris particles.

[0042] In one embodiment, Figure 8 , 10As shown in FIGS. 12 and 13, the feeding section includes a first discharge pipe 22 fixedly connected inside the crusher 1. The first discharge pipe 22 is located below the sieve plate 21. The end of the first discharge pipe 22 is fixedly connected with a second discharge pipe 35 for receiving the plastic particles screened by the grounding roller 31. The second discharge pipe 35 is located inside the sorting box 36. Receiving funnels are arranged at the tops of the first discharge pipe 22 and the second discharge pipe 35. Spiral blades 25 are rotatably connected inside both the first discharge pipe 22 and the second discharge pipe 35. The two spiral blades 25 are drivingly connected. An inlet channel 33 is movably connected inside the sorting box 36. The inlet channel 33 is located above the grounding roller 31 and is used to convey materials to the grounding roller 31. The inlet channel 33 is inclined on one side above the grounding roller 31. One side of the first discharge pipe 22 is fixedly connected with a feed pipe 23. The feed pipe 23 is communicated with the first discharge pipe 22. The feed pipe 23 is fixedly connected inside the sorting box 36. A shaftless spiral blade 26 is rotatably connected inside the feed pipe 23. A motor three 30 for driving the shaftless spiral blade 26 is fixedly connected inside the sorting box 36. The output end of the motor three 30 is drivingly connected with the spiral blade 25 through a belt assembly. A plurality of fixed discharge openings 27 are formed at the bottom of one end of the feed pipe 23 and above the inlet channel 33. A rotary distribution pipe 24 is rotatably connected at a position corresponding to the fixed discharge openings 27 on the outer side of the feed pipe 23. One end of the rotary distribution pipe 24 is fixedly connected with a cam 38 for driving the inlet channel 33 to vibrate. Rotary discharge openings 28 corresponding to the fixed discharge openings 27 are arranged up and down in a staggered manner on the outer side of the rotary distribution pipe 24. The output end of the motor three 30 is drivingly connected with the rotary distribution pipe 24 through a connecting plate 29. The rotary distribution pipe 24 rotates on the outer side of the feed pipe 23. When the fixed discharge openings 27 correspond to the rotary discharge openings 28, the materials fall from the feed pipe 23 and are evenly discharged left and right through the rotary discharge openings 28 arranged up and down in a staggered manner.

[0043] It should be noted that in this embodiment, while the motor three 30 drives the feed pipe 23 to rotate, it drives the spiral blade 25 through a belt and a pulley. The crushed materials inside the crusher 1 enter the first discharge pipe 22 through the sieve plate 21. The spiral blade 25 conveys the internal debris to the end of the first discharge pipe 22. One side of the end of the first discharge pipe 22 is communicated with the feed pipe 23. Under the action of the shaftless spiral blade 26, the material accumulated at the end of the first discharge pipe 22 is conveyed along the feed pipe 23 to the top of the feed pipe 23 by the shaftless spiral blade 26. At the same time, the motor three 30 drives the rotary distribution pipe 24 to rotate outside the feed pipe 23 through the connecting plate 29. Rotary discharge openings 28 are provided at both the top and the bottom of the rotary distribution pipe 24, and the upper and lower two rotary discharge openings 28 are respectively located on the left and right sides. When the left rotary discharge opening 28 faces downwards and corresponds to the fixed discharge opening 27, the fixed discharge opening 27 on the left side of the feed pipe 23 starts to discharge materials. When the right rotary discharge opening 28 faces downwards and corresponds to the fixed discharge opening 27, the fixed discharge opening 27 on the right side of the feed pipe 23 starts to discharge materials. In this way, the left and right cyclic discharging is carried out to achieve uniform cloth feeding and prevent the situation of material accumulation caused by a single discharge port. The materials fall into the lower feed channel 33 through the fixed discharge opening 27. A sliding rod fixedly connected to the side of the feed channel 33 is slidably connected to the sorting box 36. A spring is sleeved outside the sliding rod. A circular protrusion is fixedly connected to the side of the cam 38. The rotary distribution pipe 24 drives the cam 38 to rotate. When the circular protrusion contacts the outer wall of the feed channel 33, under the extrusion action, the feed channel 33 moves to one side. When the cam 38 is separated from the feed channel 33, the feed channel 33 resets under the action of the spring. In this way, the vibration of the feed channel 33 is realized in a cycle, so that the materials are evenly scattered outside the feed channel 33. And periodic vibration waves will be generated during the left and right vibration. The vibration is transmitted to the materials through the wall of the channel. Affected by the vibration, the materials will displace and slide. By using the frictional force and gravity of the materials, the materials flow downward, so as to achieve discharging. After being sorted by the grounding roller 31, the plastics enter the second discharge pipe 35 along the metal on the side of the second discharge pipe 35 under the action of the brush. The spiral blade 25 rotates in the second discharge pipe 35 and discharges the materials inside the second discharge pipe 35 from one end.
