Description

Technical Field

[0001] This invention belongs to the field of metal recycling, specifically an energy-saving crushing, recycling and sorting device for waste non-ferrous metals. Background Technology

[0002] With the increasing importance of resource recycling, the recycling of scrap metal has become an indispensable part of modern industrial production. Scrap metal resources are abundant, and their recycling and reuse can not only effectively save resources but also reduce environmental pollution, making it one of the important ways to achieve a circular economy.

[0003] Currently, most scrap metal recycling processes include crushing, sorting, and reuse. In the early stages of recycling, scrap metal usually needs to be crushed to convert larger pieces of scrap metal into smaller pieces suitable for subsequent sorting. However, most existing crushing equipment suffers from low crushing efficiency during operation. The crushing process of traditional crushing devices is relatively slow, resulting in low efficiency in the subsequent sorting stage.

[0004] In the sorting process, the crushed scrap metal is transported by conveyors and is usually classified using technologies such as magnetic sorting and optical sorting. Although these sorting methods effectively separate metallic materials from other non-metallic materials, the uneven distribution of the crushed metal may cause it to pile up, affecting the sorting effect. Moreover, the crushed scrap metal may contain some lighter non-metallic materials, such as plastic and paper scraps. The presence of these light impurities further affects the accuracy of sorting and reduces the purity of the recycled metal. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides an energy-saving crushing, recycling, and sorting device for waste non-ferrous metals.

[0006] To achieve the above objectives, the present invention provides the following technical solution: the device includes a roller conveyor and a crushing chamber: A bidirectional threaded rod is mounted on both sides of the inner wall of the crushing chamber via bearings, and two sleeves are threaded on the outer surface of the bidirectional threaded rod. The bidirectional threaded rod can rotate via bearings. There are two threaded grooves with different directions of rotation on the outer surface of the bidirectional threaded rod, and the two sleeves are respectively connected to the two threaded grooves with different directions of rotation. Two transmission plates are movably disposed on the inner walls of the two sleeves, and a connecting plate is movably disposed at one end of the two transmission plates. The upper ends of the two transmission plates move downward in opposite directions to push the connecting plate, and the upper ends of the two transmission plates move upward in opposite directions to pull the connecting plate. The pressure plate is fixedly disposed on one side of the connecting plate and slidably disposed on the inner wall of the crushing chamber. The pressure plate can slide on the inner wall of the crushing chamber, so that when the bidirectional threaded rod rotates in different directions, the two sleeves move in opposite or opposite directions on the outer surface of the bidirectional threaded rod. The first pulley is fixedly sleeved on the outer surface of the bidirectional threaded rod, and a belt is provided on the outer surface of the first pulley. When the second pulley rotates, it drives the first pulley to rotate through the belt.

[0007] In the above technical solution, preferably, the crushing chamber is fixedly installed on one side of the roller conveyor. Two roller shafts are mounted on both sides of the inner wall of the crushing chamber via bearings. Spur gears are fixedly sleeved on the outer surfaces of both roller shafts, and the outer surfaces of the two spur gears mesh with each other. Crushing rollers are mounted on the outer surfaces of the two roller shafts. A first motor is installed on one side of the crushing chamber, and the output shaft of the first motor is fixedly installed at one end of one of the roller shafts. A second pulley is fixedly sleeved on the outer surface of one of the roller shafts, and the outer surface of the second pulley is located on the inner wall of the belt. A feed hopper is installed on one side of the crushing chamber. A protective box is installed on the side of the crushing chamber near the two spur gears via screws. Scrap metal is fed through the feed hopper. The waste metal is poured into the crushing chamber. At this time, the external power switch of the first motor is turned on, and the output shaft of the first motor can rotate in both directions. The output shaft of the first motor drives one of the rollers to rotate clockwise, which in turn drives one of the spur gears to rotate clockwise. Through another spur gear, it drives the other roller to rotate counterclockwise. The protective box protects its internal structure and prevents it from being exposed and damaged. This causes the two crushing rollers to move relative to each other under the drive of the two rollers. At this time, the scrap metal is in the gap between the two crushing rollers. The two crushing rollers rotating in opposite directions crush the metal and push the connecting plate downward, which in turn causes the pressure plate to move downward inside the crushing chamber, further pushing the scrap metal below and increasing the compression force of the crushed scrap metal.

[0008] In the above technical solution, preferably, a discharge pipe is fixedly installed on one side of the crushing chamber, and a support box is fixedly installed on one side of the discharge pipe. A round rod is installed at the center of one side of the inner wall of the support box through a bearing. The crushed metal falls into the interior of the roller conveyor through the discharge pipe.

[0009] In the above technical solution, preferably, a fan blade is installed at one end of the round rod, and a connecting rod is provided on one side of the support box through a bearing. The rotation of the support box drives the fan blade to rotate, and the rotation of the fan blade drives the airflow. The airflow blows into the inside of the discharge pipe, and the crushed metal falls into the inside of the roller conveyor through the discharge pipe. At this time, the airflow drives the separation of lighter non-metallic materials such as plastic and paper scraps from the metal.

[0010] In the above technical solution, preferably, a second bevel gear is fixedly provided at one end of the connecting rod, and a first bevel gear is fixedly sleeved on the outer surface of the round rod. The outer surfaces of the second bevel gear and the first bevel gear mesh with each other. A material box is fixedly provided on the side of the discharge pipe away from the support box. When the connecting rod rotates, it drives the second bevel gear to rotate, and further drives the first bevel gear to rotate through the second bevel gear, so that lighter materials are blown into the interior of the material box.

[0011] In the above technical solution, preferably, a second sprocket is fixedly sleeved on the outer surface of the connecting rod, a chain is provided on the outer surface of the second sprocket, and a first sprocket is provided on the inner wall of the chain. The chain drives the second sprocket to rotate, and the rotation of the second sprocket drives the connecting rod to rotate.

[0012] In the above technical solution, preferably, a base is fixedly provided on one side of the roller conveyor, and reciprocating screws are movably provided on both sides of the inner wall of the base. The outer surface of the reciprocating screws is fixedly embedded in the inner wall of the first sprocket. The reciprocating screws can rotate, and the rotation of the reciprocating screws disperses and crushes the metal, while driving the first sprocket to rotate.

[0013] In the above technical solution, preferably, a slider is threaded on the outer surface of the reciprocating screw, and the slider is slidably disposed on the inner wall of the base. The slider can slide on the inner wall of the base, and when the reciprocating screw rotates, the slider moves back and forth along the axis of the reciprocating screw.

[0014] In the above technical solution, preferably, a second motor is installed on one side of the base, and the output shaft of the second motor is fixedly set at one end of the reciprocating lead screw. When the external power switch of the second motor is turned on, the output shaft of the second motor drives the reciprocating lead screw to rotate.

[0015] In the above technical solution, preferably, a bottom rod is fixedly installed on one side of the slider, an mounting plate is fixedly installed on one side of the bottom rod, and multiple stirring rods are fixedly installed on one side of the mounting plate. A magnetic plate is installed on one side of the roller conveyor. The slider drives the bottom rod to move back and forth, and further drives the multiple stirring rods to move back and forth through the mounting plate. The crushed scrap metal is evenly dispersed on the roller inside the roller conveyor under the action of the multiple stirring rods, and the magnetic plate adsorbs the magnetic metals in the metal.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. In the recycling of scrap metal, this invention involves pouring a batch of scrap metal into the crushing chamber through a feed hopper. At this time, the external power switch of the first motor is turned on, allowing the output shaft of the first motor to rotate in both directions. This drives one of the rollers to rotate clockwise, which in turn drives one of the spur gears to rotate clockwise. This, in turn, drives another roller to rotate counter-clockwise via another spur gear. The scrap metal is positioned in the gap between the two crushing rollers, and the two counter-rotating rollers crush the metal. Simultaneously, the rotation of the other roller drives the second pulley to rotate counter-clockwise, which in turn drives the first... The rotation of one pulley causes the first pulley to rotate, which in turn drives the double-threaded rod to rotate counterclockwise. This causes the two sleeves to move relative to each other. The relative movement of the two sleeves causes the upper ends of the two transmission plates to gradually move closer together, further pushing the connecting plate downwards. This further causes the pressure plate to move downwards inside the crushing chamber, further pushing the scrap metal below and increasing the compression force of the crushed scrap metal. This allows the scrap metal to fully contact between the two crushing rollers and be subjected to uniform pressure, thus providing additional pressure to the scrap metal during crushing. This effectively crushes larger pieces of material into smaller particles, improving crushing efficiency.

[0017] 2. In this invention, when the device is in use, the reciprocating screw rotates to disperse and crush the metal, simultaneously driving the first sprocket to rotate. This, in turn, drives the second sprocket via a chain. The rotation of the second sprocket drives the connecting rod to rotate, which in turn drives the second bevel gear to rotate. This second bevel gear then drives the first bevel gear to rotate, which in turn drives the fan blades to rotate via the support box. The rotation of the fan blades causes airflow, which blows into the inside of the discharge pipe. The crushed metal falls through the discharge pipe into the inside of the roller conveyor. At this time, the airflow carries lighter non-metallic materials such as plastics and paper scraps away from the metal, ensuring the purity of the metal in the subsequent recycling process. The lighter materials are blown into the material box. Thus, when using the device, the purity of the recycled metal is effectively improved, impurity pollution is reduced, and the recycling efficiency of scrap metal is increased.

[0018] 3. In this invention, after the scrap metal is crushed, the crushed metal falls through the feed pipe onto the rollers inside the roller conveyor. The rollers transport the crushed metal. When crushing scrap metal, the external power switch of the second motor is turned on, and the output shaft of the second motor drives the reciprocating screw to rotate. The slider can slide on the inner wall of the base. When the reciprocating screw rotates, the slider moves back and forth along the axis of the reciprocating screw, which in turn drives the base rod to move back and forth. Furthermore, the mounting plate drives multiple stirring rods to move back and forth. Under the action of multiple stirring rods, the crushed scrap metal is evenly dispersed on the rollers inside the roller conveyor. The magnetic plate attracts the magnetic metals in the metal, thus evenly dispersing the crushed metal when using the device, which helps with subsequent sorting and improves sorting accuracy.

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] like Figures 1 to 8 As shown, this invention provides an energy-saving crushing, recycling, and sorting device for waste non-ferrous metals. The device includes a roller conveyor 1 and a crushing chamber 2. A bidirectional threaded rod 201 is mounted on both sides of the inner wall of the crushing chamber 2 via bearings. Two sleeves 202 are threaded onto the outer surface of the bidirectional threaded rod 201. The bidirectional threaded rod 201 can rotate via bearings. The outer surface of the bidirectional threaded rod 201 has two threaded grooves with different helical directions. The two sleeves 202 are respectively connected to the two threaded grooves with different helical directions. Two transmission plates 203 are movably mounted on the inner walls of the two sleeves 202. A connecting plate 204 is movably mounted at one end of each transmission plate 203. The upper ends of the two transmission plates 203 are opposite to each other. The directional movement pushes the connecting plate 204, and the upper ends of the two transmission plates 203 move in opposite directions to pull the connecting plate 204; the pressure plate 205 is fixedly set on one side of the connecting plate 204, and the pressure plate 205 is slidably set on the inner wall of the crushing chamber 2. The pressure plate 205 can slide on the inner wall of the crushing chamber 2, so that when the bidirectional threaded rod 201 rotates in different directions, the two sleeves 202 move in opposite or opposite directions on the outer surface of the bidirectional threaded rod 201; the first pulley 206 is fixedly sleeved on the outer surface of the bidirectional threaded rod 201, and a belt 207 is provided on the outer surface of the first pulley 206. The second pulley 208 rotates, and drives the first pulley 206 to rotate through the belt 207.

[0030] Please see Figures 1 to 8In one embodiment, the crushing chamber 2 is fixedly installed on one side of the roller conveyor 1. Two roller shafts 209 are mounted on both sides of the inner wall of the crushing chamber 2 via bearings. Spur gears 212 are fixedly fitted onto the outer surfaces of both roller shafts 209, and the outer surfaces of the two spur gears 212 mesh with each other. Crushing rollers 210 are mounted on the outer surfaces of the two roller shafts 209. A first motor 211 is installed on one side of the crushing chamber 2. The output shaft of the first motor 211 is fixedly installed at one end of one of the roller shafts 209. A second pulley 208 is fixedly fitted onto the outer surface of one of the roller shafts 209, and the outer surface of the second pulley 208 is located on the inner wall of the belt 207. A feed hopper 214 is installed on one side of the crushing chamber 2. A protective box 213 is screwed onto the side of the crushing chamber 2 closest to the two spur gears 212. Scrap metal is poured into the interior of the crushing chamber 2 through the feed hopper 214. At this time, the outer side of the first motor 211 is opened. The power switch allows the output shaft of the first motor 211 to rotate in both directions. This drives one of the roller shafts 209 to rotate clockwise, which in turn drives one of the spur gears 212 to rotate clockwise. The other spur gear 212 then drives the other roller shaft 209 to rotate counterclockwise. The protective box 213 protects the internal structure, preventing damage from exposure. This causes the two crushing rollers 210 to move relative to each other under the influence of the two roller shafts 209. At this point, the scrap metal is positioned in the gap between the two crushing rollers 210. The two opposing crushing rollers 210 crush the metal, pushing the connecting plate 204 downward. This causes the pressure plate 205 to move downward inside the crushing chamber 2, further pushing the scrap metal below and increasing the compression force of the crushed scrap metal. This ensures that the scrap metal can fully contact the two crushing rollers 210 and be subjected to uniform pressure.

[0031] Please see Figures 1 to 8 In one embodiment, a discharge pipe 3 is fixedly installed on one side of the crushing chamber 2, and a support box 301 is fixedly installed on one side of the discharge pipe 3. A round rod 302 is installed at the center of one side of the inner wall of the support box 301 through a bearing. The crushed metal falls into the inside of the roller conveyor 1 through the discharge pipe 3, and the round rod 302 can rotate.

[0032] Please see Figures 1 to 8 In one embodiment, a fan blade 303 is installed at one end of the round rod 302, and a connecting rod 304 is provided on one side of the support box 301 through a bearing. The rotation of the support box 301 drives the fan blade 303 to rotate. When the fan blade 303 rotates, it drives the air to flow. The flowing air blows into the inside of the discharge pipe 3. The crushed metal falls into the inside of the roller conveyor 1 through the discharge pipe 3. At this time, the flowing air drives the lighter non-metallic materials such as plastic and paper scraps to separate from the metal.

[0033] Please see Figures 1 to 8In one embodiment, a second bevel gear 306 is fixedly provided at one end of the connecting rod 304, and a first bevel gear 305 is fixedly sleeved on the outer surface of the round rod 302. The outer surfaces of the second bevel gear 306 and the first bevel gear 305 mesh with each other. A material box 307 is fixedly provided on the side of the discharge pipe 3 away from the support box 301. When the connecting rod 304 rotates, it drives the second bevel gear 306 to rotate, and further drives the first bevel gear 305 to rotate through the second bevel gear 306, so that lighter materials are blown into the interior of the material box 307.

[0034] Please see Figures 1 to 8 In one embodiment, a second sprocket 310 is fixedly sleeved on the outer surface of the connecting rod 304, a chain 309 is provided on the outer surface of the second sprocket 310, and a first sprocket 308 is provided on the inner wall of the chain 309. The chain 309 drives the second sprocket 310 to rotate, and the second sprocket 310 rotates, causing the connecting rod 304 to rotate.

[0035] Please see Figures 1 to 8 In one embodiment, a base 4 is fixedly provided on one side of the roller conveyor 1, and a reciprocating screw 401 is movably provided on both sides of the inner wall of the base 4. The outer surface of the reciprocating screw 401 is fixedly embedded in the inner wall of the first sprocket 308. The reciprocating screw 401 can rotate, and the rotation of the reciprocating screw 401 disperses and breaks the metal, while driving the first sprocket 308 to rotate.

[0036] Please see Figures 1 to 8 In one embodiment, a slider 402 is threadedly sleeved on the outer surface of the reciprocating screw 401. The slider 402 is slidably disposed on the inner wall of the base 4. The slider 402 can slide on the inner wall of the base 4. When the reciprocating screw 401 rotates, the slider 402 reciprocates axially with the reciprocating screw 401.

[0037] Please see Figures 1 to 8 In one embodiment, a second motor 406 is installed on one side of the base 4. The output shaft of the second motor 406 is fixedly set at one end of the reciprocating lead screw 401. When the external power switch of the second motor 406 is turned on, the output shaft of the second motor 406 drives the reciprocating lead screw 401 to rotate.

[0038] Please see Figures 1 to 8In one embodiment, a bottom rod 403 is fixedly provided on one side of the slider 402, an mounting plate 404 is fixedly provided on one side of the bottom rod 403, and a plurality of stirring rods 405 are fixedly provided on one side of the mounting plate 404. A magnetic plate 407 is installed on one side of the roller conveyor 1. The slider 402 drives the bottom rod 403 to move back and forth, and further drives the plurality of stirring rods 405 to move back and forth through the mounting plate 404. The crushed scrap metal is evenly dispersed on the roller inside the roller conveyor 1 under the action of the plurality of stirring rods 405, and the magnetic metal in the metal is adsorbed by the magnetic plate 407.

[0039] The working principle and usage process of this invention are as follows: When recycling scrap metal, a batch of scrap metal is poured into the crushing chamber 2 through the feed hopper 214. At this time, the external power switch of the first motor 211 is turned on, and the output shaft of the first motor 211 can rotate in both directions. The output shaft of the first motor 211 drives one of the roller shafts 209 to rotate clockwise, further driving one of the spur gears 212 to rotate clockwise. The other spur gear 212 drives the other roller shaft 209 to rotate counterclockwise. The protective box 213 protects its internal structure, preventing damage from exposure. Furthermore, the two crushing rollers 210 move relative to each other under the drive of the two roller shafts 209. At this time, the scrap metal is located in the gap between the two crushing rollers 210. The two counterclockwise rotating crushing rollers 210 crush the metal. Simultaneously, when the other roller shaft 209 rotates, it drives the second pulley 208 to rotate counterclockwise, which in turn drives the first pulley 206 to rotate via the belt 207. This further causes the first pulley 206 to rotate, thus… The bidirectional threaded rod 201 rotates counterclockwise. Since there are two threaded grooves with different directions of rotation on the outer surface of the bidirectional threaded rod 201, the two sleeves 202 are connected to the two threaded grooves with different directions of rotation respectively, and the pressure plate 205 can slide on the inner wall of the crushing chamber 2. Thus, when the bidirectional threaded rod 201 rotates in different directions, the two sleeves 202 move in opposite or opposite directions on the outer surface of the bidirectional threaded rod 201. At this time, the bidirectional threaded rod 201 rotates counterclockwise, causing the two sleeves 202 to move relative to each other. The relative movement of the two sleeves 202 causes the upper ends of the two transmission plates 203 to gradually move closer together, further pushing the connecting plate 204 downward, further causing the pressure plate 205 to move downward inside the crushing chamber 2, further pushing the scrap metal below, increasing the compression force of the crushed scrap metal, so that the scrap metal can fully contact between the two crushing rollers 210 and be subjected to uniform pressure, thereby providing additional pressure to the scrap metal when crushing it, effectively crushing larger pieces of material into smaller particles, and improving crushing efficiency. After the scrap metal is crushed, the crushed metal falls through the feed pipe 3 onto the rollers inside the roller conveyor 1. The rollers transport the crushed metal. When crushing scrap metal, the external power switch of the second motor 406 is turned on, and the output shaft of the second motor 406 drives the reciprocating screw 401 to rotate. The slider 402 can slide on the inner wall of the base 4. When the reciprocating screw 401 rotates, the slider 402 moves back and forth along the axis of the reciprocating screw 401. The slider 402 drives the bottom rod 403 to move back and forth, and further drives multiple stirring rods 405 to move back and forth through the mounting plate 404. Under the action of multiple stirring rods 405, the crushed scrap metal is evenly dispersed on the rollers inside the roller conveyor 1. The magnetic plate 407 adsorbs the magnetic metal in the metal, so that the crushed metal is evenly dispersed when using the device, which helps to sort the subsequent sorting and improves the sorting accuracy. When using the device, the reciprocating screw 401 rotates to disperse and crush the metal, while simultaneously driving the first sprocket 308 to rotate. This, in turn, drives the second sprocket 310 to rotate via the chain 309. The rotation of the second sprocket 310 drives the connecting rod 304 to rotate, which in turn drives the second bevel gear 306 to rotate. This, in turn, drives the first bevel gear 305 to rotate via the support box 301. The rotation of the fan blade 303 causes airflow, which blows into the discharge pipe 3. The crushed metal falls into the roller conveyor 1 through the discharge pipe 3. At this time, the airflow carries lighter non-metallic materials such as plastics and paper scraps away from the metal, ensuring the purity of the metal in the subsequent recycling process. The lighter materials are blown into the material box 307. Thus, when using the device, the purity of the recycled metal is effectively improved, impurities are reduced, and the recycling efficiency of scrap metal is increased.
