Description

Technical Field

[0001] The invention relates to the technical field of metal waste recycling, in particular to a crushing and compressing device for processing metal waste. Background Art

[0002] Metal waste often has a high recycling value. For example, metal wire, old steel bars, rusty iron wire, etc. produced by workshop turning are all metal waste. After the metal waste is crushed by a crusher, it is compressed by a metal briquetting machine and compressed into rectangular metal blocks. The crushed and compressed metal waste has higher density and strength and can be used directly as a smelting raw material, thereby improving smelting efficiency and reducing energy consumption.

[0003] However, in the process of recycling metal scraps, when the crushing roller of the pulverizer is operating, since the feed port of the pulverizer is mostly open, some metal materials will splash during the crushing process, which may easily injure surrounding personnel and pose a safety hazard. At the same time, a scraper is provided between the cutters of the crushing roller to prevent some of the crushed metal wires or metal strips from being entangled on the surface of the roller. However, the scraper will be worn out after long-term use, and the surface will become bumpy. It is also easy to hook some metal wires or metal strips, causing waste to accumulate on the surface of the scraper, affecting the normal operation of the scraper. It can only be cleaned after the work is completed. It is rather troublesome to pull out the waste materials entangled in the blade one by one. During the crushing process, friction and extrusion will occur between the crushing roller and the metal waste, thereby generating heat. As the temperature rises, the hardness and toughness of the crushing roller may change, resulting in uneven crushing force, which in turn affects the particle size distribution of the crushed material. At the same time, after the metal waste is compressed, the rectangular metal blocks are lifted out of the groove of the metal briquetting machine and fall to the ground, which will produce a large amount of metal dust and pollute the surrounding environment. Especially after some metal waste is rusted, the rusted parts on the surface are more likely to raise rust powder after being crushed. Summary of the invention

DETAILED DESCRIPTION

[0021] See also Figure 1-18A crushing and compression device for processing metal waste includes a shell 1, a metal briquetting machine 2, a conveyor belt 26, a scraper tool 6, a crushing tool 5 and a box 27. The conveyor belt 26 is used to transport the crushed metal material to the inside of the box 27. The box 27 is fixed above the metal briquetting machine 2 through a bracket. The shell 1 is also fixed above the starting position of the conveyor belt 26 through a bracket. The device also includes an exhaust mechanism 25 and an adsorption mechanism 28. Both sides of the inside of the shell 1 are rotatably connected with rotating columns 4. The crushing tool 5 is fixed to the surface of the rotating column 4. The crushing tool 5 and the rotating column 4 constitute a crushing roller. One end of the rotating column 4 on both sides extends to the outside of the shell 1 and is connected through a gear transmission. The outside of the shell 1 is also bolted with a cover shell 3. The inside of the cover shell 3 A transmission rod 11 is rotatably connected, and a drive motor 12 is also bolted to the rear of the cover shell 3. There are two groups of transmission rods 11, one group of transmission rods 11 is fixed to the output shaft of the drive motor 12, and the two groups of transmission rods 11 are connected to the rotating column 4 through gear transmission. A movable shell 8 is slidably connected to the upper part of the shell 1, and the first partition plate 9 and the second partition plate 10 are bolted to the two sides of the movable shell 8 respectively. The first partition plate 9 and the first partition plate 9 are staggered. A hopper 7 is arranged above the shell 1, and the movable shell 8 is slidably connected to the inner wall of the hopper 7. A plurality of connecting columns 14 are bolted to the top of the shell 1, and the top of the connecting column 14 is bolted to the bottom of the hopper 7. The connecting column 14 is used to support the hopper 7. The outer side is also provided with a shaking mechanism 13 for driving the movable shell 8 to move up and down. Fixed plates 15 are bolted on both sides and the upper and lower parts of the cover shell 3. A movable groove 16 is provided on the surface of the fixed plate 15. Two sides of the movable groove 16 are designed in an arc shape. These two groups are standard arcs and the center of the circle is consistent with the center of the circle of the fixed plate 15. The top of the arc is far away from the center point of the fixed plate 15. The other two sides of the movable groove 16 are also designed in an arc shape. One side is close to the scraper tool 6, and the arc is concave toward the center point of the fixed plate 15. The other group of arcs is convex away from the center point of the fixed plate 15, but not as large as the other two groups of arcs. A vertical rotation rod 18 is rotatably connected to the center of the fixed plate 15, and a transverse rotation rod 17 is also rotatably connected to the inner wall of the cover shell 3. The transverse rotation rod 17 Two groups are arranged above and below and are connected by belt transmission. The transmission rod 11 is connected with the transverse rod 17 by belt transmission, which enables the transmission rod 11 to drive the transverse rod 17 to rotate together during the rotation process. The transverse rod 17 is connected with the vertical rod 18 by bevel gear transmission. One end of the vertical rod 18 is bolted with a frame plate 19, and a slider 20 is slidably connected to the inner wall of the frame plate 19. A vertical column 21 is welded on the surface of the slider 20, and the vertical column 21 is slidably connected to the inner wall of the movable groove 16. The other side of the slider 20 is rotatably connected to the driving rod 22. Sleeves 24 are penetrated on both sides of the shell 1, and the scraper tool 6 is slidably connected to the inner wall of the sleeve 24. An arc-shaped notch is provided on the side of the scraper tool 6 close to the rotating column 4, and a connecting seat 23 is bolted on one side of the scraper tool 6.The side of the driving rod 22 away from the slider 20 is rotatably connected to the connecting seat 23.

[0022] The shaking mechanism 13 includes a fixed rod 131 and a running wheel 132. One end of the fixed rod 131 is bolted to the movable shell 8, and the running wheel 132 is bolted to the other end of the fixed rod 131. An elliptical wheel 134 in contact with the running wheel 132 is also fixed on the surface of the transmission rod 11. When working, the driving motor 12 is first turned on, and its output shaft drives the transmission rod 11 to rotate. Then the transmission rod 11 drives the rotating column 4 to rotate through the gear, and the rotating column 4 drives the crushing tool 5 to rotate. The metal waste to be crushed is put into the feed hopper 7, and the waste enters the interior of the movable shell 8. At the same time, the transmission rod 11 drives the elliptical wheel 134 to rotate. When the long end of the elliptical wheel 134 contacts the running wheel 132, it can drive the fixed rod 131 and the movable shell 8 to rise. When the short end of the elliptical wheel 134 contacts the running wheel 132, the movable shell 8 descends. It makes the movable shell 8 reciprocate up and down. The surface of the movable shell 8 is also bolted with a sliding sleeve 133, and the sliding sleeve 133 is slidably connected to the surface of the connecting column 14. During the up and down movement of the movable shell 8, the sliding sleeve 133 can be driven to reciprocate up and down along the connecting column 14, thereby increasing the stability of the up and down movement of the movable shell 8. The metal waste falls on the surface of the first partition 9 or the second partition 10, and under the action of the up and down shaking of the movable shell 8, it slides down along the surface of the two groups of partitions and falls into the center of the two groups of rotating crushing cutters 5 to crush the metal waste. In addition, during the crushing process, with the shielding of the first partition 9 and the second partition 10, the bounced metal waste will not fly out of the movable shell 8 and the hopper 7, thereby avoiding injuring the surrounding staff. At the same time, the movable shell 8 shaking up and down is also conducive to the waste sliding downward along the surface of the first partition 9 and the second partition 10.

[0023] When the transmission rod 11 rotates, it can drive the transverse rod 17 to rotate through the belt, and the transverse rod 17 drives the vertical rod 18 to rotate through the bevel gear, and then the vertical rod 18 drives the frame plate 19 to rotate, thereby driving the surface slider 20 to make a circular motion, and the slider 20 can drive the vertical column 21 to slide along the inner wall of the movable groove 16, and at the same time, the slider 20 drives one end of the driving rod 22 to move. When along the standard arc position of the movable groove 16, the slider 20 and the vertical column 21 make normal arc motion, and at the same time, the driving rod 22 pushes the connecting seat 23 and the scraper 6 to make them close to the rotating column 4. When the slider 20 and the vertical column 21 move to the position of the movable groove 16 close to the scraper 6, the slider 20 slides along the surface of the frame plate 19 and approaches the center of the fixed disk 15, and at the same time drives one end of the driving rod 22 to also approach the center of the fixed disk 15, so that the connecting seat 23 stays for a period of time. At this time, the scraper 6 approaches the rotating column 4, thereby blocking part of the metal wire on the surface of the rotating column 4. As the crushing tool 5 or the rotating column 4 rotates, the upper and lower groups of vertical columns 21 rotate synchronously, but the starting positions of the frame plate 19 are different, so the other group of connecting seats 23 and the scraper tool 6 move in the direction away from the scraper tool 6, and under the action of the other group of edges of the movable groove 16, the other group of connecting seats 23 and the scraper tool 6 stay briefly, and the scraper tool 6 retracts to the side of the sleeve 24 away from the crushing tool 5. Therefore, in the process of the frame plate 19 driving the slider 20 and the vertical column 21 to move along the movable groove 16, the scraper tool 6 and the connecting seat 23 move back and forth and can stay for a part of the time, allowing one group of scraper tools 6 to perform the cleaning function, and the other group retreats to the inside of the sleeve 24. The metal wire hooked on the surface of the scraper tool 6 falls off under the action of the blocking of the sleeve 24, preventing the metal wire entangled and hooked on the surface of the scraper tool 6 from hindering its normal operation. At the same time, the scraper tools 6 on the upper and lower sides perform cleaning alternately, and also avoid the metal wire entangled on the surface of the crushing roller due to being away from the crushing roller during the retreat of the scraper tool 6.

[0024] The exhaust mechanism 25 includes a fan 251, an air supply pipe 252 and a first cover body 253. The fan 251 is bolted to the top of the box body 27. The air supply pipe 252 is connected to the air outlet of the fan 251. The first cover body 253 is connected to one end of the air supply pipe 252 away from the fan 251. A plurality of connecting pipes 254 are connected to the side of the first cover body 253 away from the air supply pipe 252. The interior of the sleeve 24 is a sandwich design. An exhaust hole 257 is opened through the inner wall of the sleeve 24. The inner wall of the exhaust hole 257 is inclined so that the exhaust hole 257 is aligned with the crushing cutter 5. The surface of the sleeve 24 is also connected with a short tube 256. The number of the short tubes 256 is several and corresponds to the number of the sleeve 24. One end of the short tube 256 is connected with the second cover body 255. The connecting pipe 254 The other end away from the first cover body 253 is connected to the second cover body 255, thereby connecting the first cover body 253 and the second cover body 255 together. During the crushing process, the fan 251 is turned on to exhaust air, which allows the air to pass through the air supply pipe 252, the first cover body 253, the connecting pipe 254 and the second cover body 255, and then be discharged through the short pipe 256 and the exhaust hole 257. When the scraper tool 6 retracts to the inside of the sleeve 24 to half of its middle part, the scraper tool 6 no longer blocks the exhaust hole 257. When the scraper tool 6 passes by, air is blown toward the surface of the scraper tool 6, making it easier to fall off the hooked metal wire, and the blown air can also reach the surface of the rotating column 4 and the crushing tool 5, to a certain extent, cool the crushing roller composed of the rotating column 4 and the crushing tool 5 to prevent its temperature from rising.

[0025] The adsorption mechanism 28 includes an air inlet channel 281, a fan 282 and a transverse channel 283. The number of air inlet channels 281 is several and they are connected and arranged on one side of the box body 27. The fan 282 is bolted to the inner side of the air inlet channel 281. The transverse channel 283 is connected and arranged on the other side of the box body 27. A vertical cylinder 286 is also arranged on one side of the box body 27 and above the metal briquetting machine 2. The other side of the transverse channel 283 is connected to the vertical cylinder 286. The interior of the transverse channel 283 close to the side of the box body 27 is also bolted with a first blocking net 284 to prevent metal scraps from entering the interior of the transverse channel 283. The mesh aperture of the surface of the first blocking net 284 is relatively large. The interior of the vertical cylinder 286 is also bolted. It is connected to an inner cylinder 285, and vertical plates 288 are bolted on both sides of the inner wall of the inner cylinder 285. An electromagnet 289 is fixed on the surface of the vertical plate 288. The inner cylinder 285 is made of metal, and the magnetic poles of the electromagnet 289 fit the inner wall of the inner cylinder 285. Vibration motors 2810 are bolted on both the upper and lower sides of the inner cylinder 285. A second blocking net 2811 is bolted on the upper part of the vertical cylinder 286. The mesh aperture of the second blocking net 2811 is smaller than the mesh aperture of the first blocking net 284. The second blocking net 2811 is used to intercept metal dust and prevent it from entering the interior of the fan 251. A connecting pipe 2812 is connected to the inlet of the fan 251, and the other end of the connecting pipe 2812 is connected to the top of the vertical cylinder 286.

[0026] The crushed metal waste falls from the bottom of the shell 1 to the surface of the conveyor belt 26, and the conveyor belt 26 transports the crushed waste to the inside of the box 27. The fan 282 is turned on to blow air into the inside of the box 27. The crushed metal waste falls inside the box 27, and the fan 282 can blow away a large amount of metal dust therein. At the same time, the fan 251 is turned on to generate suction at its inlet, which allows the air inside the vertical cylinder 286 to enter the inside of the fan 251 through the connecting pipe 2812, allowing the air inside the vertical cylinder 286 to flow, and then the metal dust blown by the fan 282 enters the inside of the vertical cylinder 286 through the horizontal channel 283, and flows upward with the air, and the electromagnet 289 is turned on, which is inside The surface of the cylinder 285 generates an adsorption force, which allows the metal dust to be adsorbed on the surface of the vertical cylinder 286. At the same time, combined with the interception effect of the second blocking net 2811, a large amount of metal dust is blown away inside the vertical cylinder 286, and the metal waste passes through the box 27 and falls into the metal briquetting machine 2. After a certain amount of metal waste is accumulated in the groove of the metal briquetting machine 2, the conveyor belt 26 is temporarily stopped and the metal waste is stopped from being fed into the hopper 7. Then, the metal briquetting machine 2 is started to briquette the metal waste to form compressed rectangular blocks. The compressed rectangular blocks are discharged to the outside through the flipping function of the metal briquetting machine 2 itself, so that a large amount of metal dust will not be generated when the rectangular blocks fall.

[0027] A long tube 287 is also provided on one side of the vertical cylinder 286, and the other end of the long tube 287 is connected to the interior of the shell 1. Part of the metal dust generated during the crushing process can also be sucked into the interior of the vertical cylinder 286 after passing through the long tube 287, so that the generation of dust can be reduced at the source, further improving the environmental protection of the device. The bottom of the vertical cylinder 286 is connected to a bottom box 29, and a collection box 30 is slidably provided on the inner wall of the bottom box 29. A box door 31 is provided on the surface of the bottom box 29, and the box door 31 can be opened. Or turn it off. After the processing of the metal waste is completed, turn off the electromagnet 289 and turn on the vibration motor 2810 to vibrate the surface of the inner cylinder 285, so that the metal powder falls into the collection box 30. At the same time, the top of the inner cylinder 285 contacts the second blocking net 2811, and the vibration of the inner cylinder 285 is transmitted to the second blocking net 2811, so that the dust intercepted on the surface of the second blocking net 2811 also falls and falls into the collection box 30. Then open the box door 31 to take out the collection box 30 filled with powder.
