Description

Technical Field

[0001] The invention relates to the technical field of plastic masterbatch production, and more specifically to a PP plastic masterbatch magnetic separation device. Background Art

[0002] PP plastic masterbatch is an important plastic raw material. Its full name is polypropylene plastic masterbatch. PP plastic masterbatch is mainly composed of polypropylene as the base material, and various additives, fillers and a small amount of carrier resin are added. It has excellent weather resistance, heat resistance and chemical stability, so it is widely used in various fields. When processing PP plastic masterbatch, magnetic separation equipment is required to adsorb the ferromagnetic impurities remaining in the PP plastic masterbatch.

[0003] The magnetic separation device for PP plastic masterbatch usually includes a feed hopper, a conveyor belt and a magnetic separation device. The plastic masterbatch enters the conveyor belt through the feed hopper, and is screened and processed by the magnetic separation device. The fine ferromagnetic impurities in the PP plastic masterbatch can be adsorbed and discharged from the device in time to prevent affecting the magnetic separation effect of the magnetic separation unit.

[0004] In the prior art, when PP plastic masterbatch needs to be subjected to magnetic separation processing, since the PP plastic masterbatch is directly placed in the feed hopper, the PP plastic masterbatch will be accumulated in one place. The accumulation of PP plastic masterbatch in one place will easily lead to a large number of PP plastic masterbatch concentrated in one place on the conveyor belt, which will affect the magnetic separation. Therefore, the operator is required to manually turn the PP plastic masterbatch evenly so that the PP plastic masterbatch can fall evenly on the conveyor belt.

[0017] (1) By starting the uniform component, the first push plate, the connecting strip and the second push plate are driven to move to one side together. When the first push plate and the two groups of second push plates move, the PP plastic masterbatch in the feed hopper can be pushed to both sides. Since the bottoms of the first push plate and the second push plate are provided with multiple groups of round holes, when the PP plastic masterbatch is pushed, part of the PP plastic masterbatch will pass through the first push plate and the second push plate, which is conducive to the uniform leveling of the PP plastic masterbatch in the feed hopper. By setting a vibration component, the push block can be driven to move back and forth when the uniform component is running, so that the base can be knocked to cause slight vibration of the base, which is conducive to the PP plastic masterbatch in the feed hopper falling downward, solving the problem that the PP plastic masterbatch is not easy to be uniformly discharged during magnetic separation processing.

[0018] (2) By setting up a re-selection component, the central shaft and the outer cylinder can be driven to rotate when the rotating motor is running. The first magnet and the second magnet in the outer cylinder cooperate to make the outer cylinder magnetic, and the PP plastic masterbatch above the second conveyor belt is magnetically separated again by the outer cylinder, which is beneficial to adsorb the missed magnetic metal impurities.

[0019] (3) By setting up a collecting assembly, when the magnetic separation process is completed, the annular plate and the multiple groups of long rods can be driven to rotate by the toggle rod, and the pull rope is pushed by the long rod, so that the pull rope drives the installation sleeve and the first magnetic block to move toward the outer wall of the cylinder. When the toggle rod slides to the end of the arc groove, the fixed block can be rotated to fix the position of the toggle rod, so that the multiple groups of installation sleeves and the first magnetic block are moved away from the gap between the second magnetic block, so that the local area on the surface of the outer cylinder loses magnetic force. When the outer wall of the outer cylinder rotates inside the top plate, the magnetic impurities adsorbed by the second magnet can be scraped off by the scraper inside the top plate. Since there is a gap in the area adsorbed by the second magnet, there is a gap between the multiple groups of impurities, which can facilitate the removal of impurities, and the scraped magnetic impurities will fall into the collection box inside the top plate.

[0034] Embodiment 1

[0035] Reference Figure 1-11A PP plastic masterbatch magnetic separation device comprises a processing table 1, a first conveyor belt 2 is fixedly connected to the top of the processing table 1, a second conveyor belt 3 is fixedly connected to the inner wall of the processing table 1, a drop plate 4 is fixedly connected to one side of the processing table 1, a scraper 5 and a lower hopper 6 are fixedly connected to the bottom of the processing table 1, the lower hopper 6 is arranged at the bottom of the first conveyor belt 2, an inclined plate 7 is fixedly connected to the inner wall of the processing table 1, a base 8 is fixedly connected to the top of the processing table 1, and a feed hopper 9 is fixedly connected to the top of the base 8, and further comprises:

[0036] A first push plate 20, which is disposed inside the feed hopper 9, a connecting strip 21 is fixedly connected to one side of the first push plate 20, a second push plate 22 is fixedly connected to the other end of the connecting strip 21, a circular hole is provided at the bottom of the first push plate 20 and the second push plate 22, and a uniform component for driving the first push plate 20 is provided on one side of the feed hopper 9;

[0037] A push block 32, the push block 32 is arranged on one side of the base 8, a long strip 33 is fixedly connected to one side of the base 8, the push block 32 is slidably connected to the outer wall of the long strip 33, and a vibration component for promoting uniform material feeding is arranged on one side of the push block 32;

[0038] An outer cylinder 39, the outer cylinder 39 is rotatably connected to the top of the processing table 1, a first magnetic block 43 is provided on the inner wall of the outer cylinder 39, a second magnetic block 46 is fixedly connected to the inner wall of the outer cylinder 39, and a check assembly for secondary screening is provided on one side of the outer cylinder 39;

[0039] The long rod 47 is arranged on the inner wall of the outer cylinder 39. An annular plate 48 is fixedly connected to one side of the long rod 47. A collecting component for collecting the selected impurities is arranged inside the outer cylinder 39.

[0040] In order to solve the problem that PP plastic masterbatch is not easy to be uniformly discharged during magnetic separation processing, when PP plastic masterbatch needs to be magnetically separated, the PP plastic masterbatch can be placed in the feed hopper 9, and the first push plate 20, the connecting strip 21 and the second push plate 22 can be driven to move to one side by starting the uniform component. The PP plastic masterbatch in the feed hopper 9 can be pushed to both sides by the first push plate 20 and the two groups of second push plates 22. Since the bottoms of the first push plate 20 and the second push plate 22 are provided with multiple groups of round holes, when the PP plastic masterbatch is pushed, part of the PP plastic masterbatch will pass through the first push plate 20 and the second push plate 22, which is conducive to the uniform paving of the PP plastic masterbatch in the feed hopper 9. By setting a vibration component, the push block 32 can be driven to move back and forth when the uniform component is running, so that the base 8 can be knocked to make the base 8 vibrate slightly, which is conducive to the PP plastic masterbatch in the feed hopper 9 falling downward. When the PP plastic masterbatch falls to the top of the first conveyor belt 2, the first conveyor belt 2 is magnetic and thus absorbs the fine magnetic metal in the PP plastic masterbatch. When the PP plastic masterbatch is conveyed to the end of the first conveyor belt 2, it falls onto the second conveyor belt 3. By setting the inclined plate 7, the PP plastic masterbatch can be guided to the top of the second conveyor belt 3, and the fine magnetic metal impurities can move downward along the first conveyor belt 2 and be scraped off by the scraper 5. The magnetic metal impurities can be collected by the lower hopper 6, and the PP plastic masterbatch on the second conveyor belt 3 can be collected downward by the drop plate 4. By setting the re-selection component, the outer cylinder 39 can be magnetized by the cooperation of the first magnet and the second magnet, and the magnetic separation process can be performed again from the top of the PP plastic masterbatch, which can be beneficial to the adsorption process of the missed magnetic metal impurities. By setting the collecting component, the magnetic metal adsorbed on the outer cylinder 39 can be collected.

[0041] Reference Figure 4-5 The uniform component also includes a mounting frame 10, which is fixedly connected to one side of the processing table 1, and a rotating motor 11 is fixedly connected to the top of one side of the mounting frame 10, and a transmission rod 12 is fixedly connected to the output end of the rotating motor 11, and one end of the transmission rod 12 is fixedly connected to a first bevel gear 13, and one side of the first bevel gear 13 is meshed with a second bevel gear 14, and one side of the second bevel gear 14 is fixedly connected to a first round rod 15, and the other end of the first round rod 15 is fixedly connected to a disc 16, and one end of the disc 16 away from the first round rod 15 is fixedly connected to a protrusion 17, and the top of the first push plate 20 is fixedly connected to a connecting block 19, and one side of the connecting block 19 is fixedly connected to a frame plate 18, and the shape of the frame plate 18 is a long strip 33, and the protrusion 17 is slidably connected to the inner wall of the frame plate 18, and a square groove 24 is opened at the top of one side of the feed hopper 9, and a block 23 is fixedly connected to the bottom of the connecting block 19, and the block 23 is slidably connected to the inner wall of the square groove 24.

[0042] When the PP plastic masterbatch needs to be evenly paved, the rotating motor 11 can be started, and the transmission rod 12 and the first bevel gear 13 on one side are driven to rotate by the rotating motor 11, and the second bevel gear 14 is driven to rotate by the rotation of the first bevel gear 13. When the second bevel gear 14 rotates, the first round rod 15 set on one side is driven to rotate, and the disc 16 and the protrusion 17 are driven to rotate together by the first round rod 15. Since the protrusion 17 is set at the edge of the disc 16, the protrusion 17 will drive the disc 16 to rotate when the disc 16 rotates. The frame plate 18 moves reciprocatingly, and when the frame plate 18 moves, it will drive the connecting block 19, the first push plate 20, the connecting strip 21 and the second push plate 22 to move reciprocatingly together, so that the PP plastic masterbatch in the feed hopper 9 can be evenly flattened by the first push plate 20 and the second push plate 22, and a square groove 24 is provided at the top of the feed hopper 9. When the connecting block 19 moves, the square block 23 can slide in the square groove 24 to limit the moving trajectory of the connecting block 19, the frame plate 18, the first push plate 20, the connecting strip 21 and the second push plate 22.

[0043] Reference Figure 6-7 The vibration assembly also includes a bracket 25, which is fixed to one side of the processing table 1. A first ring is fixed to the top of the bracket 25, and the first ring is sleeved on the outer wall of the first round rod 15. A first gear 26 is fixed to the outer wall of the first round rod 15. A second gear 27 is meshed at the bottom of the first gear 26. A second round rod is fixed to one side of the second gear 27. A half tooth 28 is fixed to the end of the second round rod away from the second gear 27. A second ring is fixed to the top at the center of the bracket 25, and the second ring is sleeved on the outer wall of the second round rod. A third ring is fixedly connected to the top of the other end of the bracket 25, and a third round rod is sleeved inside the third ring. A third gear 29 is fixedly connected to one end of the third round rod, and the third gear 29 is arranged at the bottom of the half tooth 28. A first connecting rod 30 is fixedly connected to one end of the third round rod away from the third gear 29, and a second connecting rod 31 is rotatably connected to one end of the first connecting rod 30. One end of the push block 32 is rotatably connected to one end of the second connecting rod 31. A side plate 34 is fixedly connected to one side of the base 8. Two groups of side plates 34 are provided and are symmetrically distributed at both ends of the long strip 33.

[0044] When the first round rod 15 rotates, it drives the first gear 26 arranged on the outer wall to rotate, and when the first gear 26 rotates, it drives the second gear 27 at the bottom to rotate together, and when the second gear 27 rotates, it drives the second round rod and the half gear 28 on one side to rotate, and the half gear 28 drives the third gear 29 at the bottom to rotate intermittently, and when the third gear 29 rotates intermittently, it drives the third round rod on one side to rotate, and when the third round rod rotates, it drives the first connecting rod 30 and the second connecting rod 31 to rotate, and When the second connecting rod 31 rotates, it will drive the push block 32 to slide on the outer wall of the long strip 33. When the push block 32 slides to the edge of the long strip 33, it will hit the side plate 34, causing the side plate 34 to vibrate. The vibration will be transmitted to the base 8 and the feed hopper 9, thereby causing the PP plastic masterbatch in the feed hopper 9 to fall downward. Since the third round rod, the first connecting rod 30 and the second connecting rod 31 rotate intermittently, the feed hopper 9 and the base 8 can be intermittently vibrated, which is conducive to the PP plastic masterbatch falling downward.

[0045] Reference Figure 8-10 The check assembly also includes a first pulley 35, which is fixedly connected to the outer wall of the transmission rod 12, and a transmission belt 36 is sleeved on the outer wall of the first pulley 35. The other end of the inner wall of the transmission belt 36 is sleeved on the second pulley 37, and a central axis 38 is fixedly connected to the center of the second pulley 37, and the central axis 38 is fixedly connected to the inner wall of the outer cylinder 39, and a cylinder 40 is fixedly connected to the inner wall of the outer cylinder 39. A spring 44 is fixedly connected to the outer wall of the cylinder 40, and a mounting sleeve 42 is fixedly connected to the top of the spring 44. The first magnetic block 43 is fixedly connected to the inner wall of the mounting sleeve 42, and the first magnetic block 43, the mounting sleeve 42, the spring 44 and the second magnetic block 46 are all provided in multiple groups and are circumferentially distributed on the inner wall of the outer cylinder 39. Multiple groups of the mounting sleeve 42 and the first magnetic block 43 are arranged in the gap between the second magnetic block 46.

[0046] When the transmission rod 12 rotates, the first pulley 35 is driven to rotate, and when the first pulley 35 rotates, the transmission belt is driven to rotate, and when the transmission belt rotates, the second pulley 37 is driven to rotate, and the second pulley 37 drives the central shaft 38 and the outer cylinder 39 to rotate together. By setting the spring 44 and the mounting sleeve 42, the position of the first magnetic block 43 can be fixed in the gap between the second magnetic blocks 46. Since the outer cylinder 39 is attached to the top of the second conveyor belt 3, the magnetic metal debris in the PP plastic masterbatch can be adsorbed through the cooperation of the first magnetic block 43 and the second magnetic block 46, which is beneficial to the magnetic separation of missed magnetic metal impurities.

[0047] Reference Figure 9-11The collecting assembly further comprises a pull rope 41, the pull rope 41 is fixedly connected to the bottom of the mounting sleeve 42, the pull rope 41 passes through the cylinder 40, the bottom of the pull rope 41 is fixedly connected to the outer wall of the central axis 38, the outer wall of the cylinder 40 is fixedly connected to a guide plate 45, the top of the guide plate 45 is fixedly connected to the bottom of the second magnetic block 46, the long rod 47 is arranged on the inner wall of the cylinder 40, the long rod 47 is provided with multiple groups, and is circumferentially distributed between the multiple groups of pull ropes 41, one side of the annular plate 48 is fixedly connected to a toggle rod 49, the outer cylinder 3 An arc groove is provided on one side of 9, and the toggle rod 49 is slidably connected to the inner wall of the arc groove. A fixed block 50 is rotatably connected to one side of the outer cylinder 39, and the inner wall shape of the fixed block 50 is arc-shaped. A top plate 51 is fixedly connected to the top of the processing table 1, and the top plate 51 is arranged on the top of the outer cylinder 39. A scraper is fixedly connected to one side of the top plate 51, and the scraper is tightly attached to one side of the outer cylinder 39. A collecting box 52 is provided on the inner wall of the top plate 51, and a handle is fixedly connected to one side of the collecting box 52, and one end of the handle extends out of the top plate 51.

[0048] After the magnetic separation of the PP plastic masterbatch is completed, a group of collection plates for collecting debris can be placed on the second conveyor belt 3, and then the toggle rod 49 can be pushed to rotate the toggle rod 49 on the inner wall of the arc groove, and the annular plate 48 on one side and the multiple groups of long rods 47 are driven to rotate together through the toggle rod 49. When the long rod 47 rotates, it will push the pull rope 41 on one side, so that the part of the pull rope 41 located on the inner wall of the cylinder 40 is pushed to one side, thereby driving the installation sleeve 42 and the first magnetic block 43 set at one end of the pull rope 41 to move toward the outer wall of the cylinder 40. By setting the guide plate 45, the moving trajectory of the installation sleeve 42 and the first magnetic block 43 can be limited. When the installation sleeve 42 and the first magnetic block 43 move, the spring 44 will be squeezed. When the toggle rod 49 slides to the end of the arc groove, the fixed block 50 can be rotated, and the fixed block 50 is buckled in The toggle rod 49 is moved to fix the position of the toggle rod 49, so that the positions of the annular plate 48 and the multiple groups of long rods 47 can be fixed, so that the multiple groups of mounting sleeves 42 and the first magnetic block 43 are moved away from the gap between the second magnetic block 46, so that the local area on the surface of the outer cylinder 39 loses its magnetic force, and the magnetic impurities dropped in the local area will be collected by the collecting plate at the bottom, and then the rotating motor 11 is started to drive the outer cylinder 39 and the central axis 38 to rotate. When the outer wall of the outer cylinder 39 rotates in the top plate 51, the magnetic impurities adsorbed by the second magnet can be scraped off by the scraper in the top plate 51. Since there are intervals in the areas adsorbed by the second magnet, intervals are set between the multiple groups of impurities, which can be beneficial to the removal of impurities, and the scraped magnetic impurities will fall into the collecting box 52 in the top plate 51, and the magnetic impurities in the collecting box 52 can be taken out by pulling the handle.

A plurality of ventilation slots are provided at the connection between the side frame 53 and the air outlet 55.

[0050] By starting the fan 54, suction can be generated on one side of the top plate 51, which can facilitate the suction of magnetic impurities on the outer cylinder 39 into the top plate 51. By providing an L-shaped air outlet 55 on one side of the side frame 53, the wind flow can be guided to be blown upwards to prevent the wind flow from affecting the PP plastic masterbatch transported on the first conveyor belt 2.

[0051] Working principle: In order to solve the problem that PP plastic masterbatch is not easy to be uniformly fed during magnetic separation processing, when PP plastic masterbatch needs to be magnetically separated, the PP plastic masterbatch can be placed in the feed hopper 9, and the transmission rod 12 and the first bevel gear 13 are driven to rotate by starting the rotating motor 11, and the second bevel gear 14 is driven to rotate by the rotation of the first bevel gear 13. When the second bevel gear 14 rotates, it will drive the first round rod 15 set on one side to rotate, and the first round rod 15 will drive the disc 16 and the protrusion 17 to rotate together. Since the protrusion 17 is set at the edge of the disc 16, the protrusion 17 will drive the frame plate 18 to reciprocate when the disc 16 rotates, and the frame plate 18 will drive the connecting block 19 and the first push block 19 when moving. The plate 20, the connecting strip 21 and the second push plate 22 move reciprocatingly together, so that the PP plastic masterbatch in the feed hopper 9 can be evenly paved by the first push plate 20 and the second push plate 22, and the top of the feed hopper 9 is provided with a square groove 24, which can be slid in the square groove 24 by the square block 23 when the connecting block 19 moves, and the moving track of the connecting block 19, the frame plate 18, the first push plate 20, the connecting strip 21 and the second push plate 22 can be limited. Since the bottoms of the first push plate 20 and the second push plate 22 are provided with multiple groups of round holes, when the PP plastic masterbatch is pushed, part of the PP plastic masterbatch will pass through the first push plate 20 and the second push plate 22, which is conducive to evenly paving the PP plastic masterbatch in the feed hopper 9. When the first gear 26 is rotated, it will drive the first gear 26 arranged on the outer wall to rotate, and the first gear 26 will drive the second gear 27 at the bottom to rotate together when rotating, and the second gear 27 will drive the second round rod and the half gear 28 on one side to rotate when rotating, and the half gear 28 will drive the third gear 29 at the bottom to rotate intermittently, and when the third gear 29 rotates intermittently, it will drive the third round rod on one side to rotate, and when the third round rod rotates, it will drive the first connecting rod 30 and the second connecting rod 31 to rotate, and when the second connecting rod 31 rotates, it will drive the push block 32 to slide on the outer wall of the long strip 33, and when the push block 32 slides to the edge of the long strip 33, it will hit the side plate 34, causing the side plate 34 to vibrate, and the vibration will be transmitted to the base 8 and the inlet The hopper 9 is provided with a first connecting rod 30 and a second connecting rod 31, thereby causing the PP plastic masterbatch in the feed hopper 9 to fall downward. Since the third round rod, the first connecting rod 30 and the second connecting rod 31 rotate intermittently, the feed hopper 9 and the base 8 can be intermittently vibrated, which is conducive to the PP plastic masterbatch falling downward. When the PP plastic masterbatch falls to the top of the first conveyor belt 2, since the first conveyor belt 2 is magnetic, the fine magnetic metal in the PP plastic masterbatch will be adsorbed. When the PP plastic masterbatch is conveyed to the end of the first conveyor belt 2, it will fall onto the second conveyor belt 3. By setting the inclined plate 7, it is conducive to guiding the PP plastic masterbatch to the top of the second conveyor belt 3, and the fine magnetic metal impurities will move downward along the first conveyor belt 2 and be scraped off by the scraper 5.The magnetic metal impurities can be collected by the lower hopper 6, and the PP plastic masterbatch on the second conveyor belt 3 will be collected downward through the drop plate 4. When the transmission rod 12 rotates, the first pulley 35 will be driven to rotate, and when the first pulley 35 rotates, the transmission belt will be driven to rotate, and when the transmission belt rotates, the second pulley 37 will be driven to rotate, and the second pulley 37 will drive the central shaft 38 and the outer cylinder 39 to rotate together. By setting the spring 44 and the mounting sleeve 42, the position of the first magnetic block 43 can be fixed at the gap between the second magnetic blocks 46. Since the outer cylinder 39 is attached to the second conveyor belt 3 The top of the PP plastic masterbatch is provided with a magnetic plate 48 and a plurality of long rods 47. The magnetic plate 48 and the plurality of long rods 47 are driven to rotate together through the toggle rod 49. When the long rod 47 rotates, the pull rope 41 on one side is pushed, so that the part of the pull rope 41 located on the inner wall of the cylinder 40 is moved to the side. The side is pushed, thereby driving the installation sleeve 42 and the first magnetic block 43 set at one end of the pull rope 41 to move toward the outer wall of the cylinder 40. By setting the guide plate 45, the movement trajectory of the installation sleeve 42 and the first magnetic block 43 can be limited. When the installation sleeve 42 and the first magnetic block 43 move, the spring 44 is squeezed. When the toggle rod 49 slides to the end of the arc groove, the fixed block 50 can be rotated. The fixed block 50 is buckled on the toggle rod 49 to fix the position of the toggle rod 49, so that the position of the annular plate 48 and the multiple groups of long rods 47 can be fixed, so that the multiple groups of installation sleeves 42 and the first magnetic block 43 are moved from the second magnetic block 46. By moving the gap, the local area on the surface of the outer cylinder 39 loses its magnetic force, and the magnetic impurities dropped from the local area will be collected by the collection plate at the bottom. Then, the rotating motor 11 is started to drive the outer cylinder 39 and the central shaft 38 to rotate. When the outer wall of the outer cylinder 39 rotates in the top plate 51, the magnetic impurities adsorbed by the second magnet can be scraped off by the scraper in the top plate 51. Since there are intervals in the areas adsorbed by the second magnet, there are intervals between multiple groups of impurities, which is conducive to the removal of impurities. The scraped magnetic impurities will fall into the collection box 52 in the top plate 51, and the magnetic impurities in the collection box 52 can be taken out by pulling the handle.
