Description

Technical Field

[0001] The invention relates to the technical field of magnetic separation equipment, in particular to an iron removal device for recycled metal recovery production. Background Art

[0002] Magnetic separator is a device that uses magnetism to separate iron from metal mixed particles. It is widely used in the fields of recycled metal recycling, mining, chemistry, etc. The permanent magnetic drum magnetic separator consists of an inner drum and an outer drum, which are connected to the conveying pipeline through upper and lower flanges. The inner drum is the magnet, which is assembled from several permanent magnets and magnetic conductive plates. The outer drum is a wear-resistant and smooth cylinder, which is driven by a pulley to rotate to achieve the adsorption and separation of magnetic metals.

[0003] The existing magnetic separator has a relatively simple structure. During the magnetic separation and screening process, the screening efficiency is greatly affected by the magnetic strength of the magnet. When the magnetic strength of the magnet is high, iron particles and fragments will be tightly adsorbed on the outer cylinder close to the magnet. At this time, the high-intensity suction will cause a part of the iron blocks to push other metals close to the outer cylinder and adsorb the iron blocks through other metals. Finally, during the screening process, a part of the iron will be mixed with other metals and output, affecting the screening efficiency. At this time, multiple screenings are required to improve the iron removal efficiency. As the equipment is used, the magnetism of the magnet will slowly weaken. When the magnetic strength is low, the mixed waste will fall faster, which will make it difficult for a part of the iron blocks to be adsorbed to the outer cylinder close to the magnet for screening and output, which will also affect the iron removal efficiency.

DETAILED DESCRIPTION

[0018] 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.

[0019] Example 1: Please refer to Figure 1-Figure 9 The iron removal device for recycling and producing recycled metals shown in the figure includes a body 1, a magnetic separation mechanism, a driving mechanism and a dust removal mechanism. The two sides of the body 1 are fixedly connected with side plates 2 respectively. The magnetic separation mechanism includes an outer cylinder 3 and a magnet 4 installed in the body 1. An outer gear ring 17 is coaxially fixedly installed at one end of the outer cylinder 3, which is used to realize the iron removal operation of the metal through the rotation of the outer cylinder 3 and the adsorption of the magnet 4. The driving mechanism includes a plurality of driving blocks 5 installed in the body 1, which are used to reciprocate by linking the plurality of driving blocks 5 during the rotation of the outer cylinder 3. The push block 5 is provided with an arc groove 7 at the bottom, which is used to intermittently connect one end of the arc groove 7 with the inner wall of the machine body 1 during the reciprocating sliding of the push block 5, so as to extract the dust inside the machine body 1 and output it to the dust removal box 6 for collection and storage.

[0020] The magnetic separation mechanism also includes a mounting frame 25 fixedly mounted on one side plate 2, the outer cylinder 3 is movably sleeved with the outer wall of the mounting frame 25, the magnet 4 is plugged into the outer wall of the mounting frame 25, the inner wall of the outer cylinder 3 is slidingly fitted with the outer wall of the magnet 4, the cross-section of the magnet 4 is arc-shaped, and the magnet 4 is located on the side close to the push block 5, a fixed box 26 is fixedly connected to the body 1, a threaded groove 38 is provided on the outer wall of one end of the mounting frame 25, a threaded ring 39 that can be threadedly connected to the threaded groove 38 is provided on the body 1, and a rotating ring 40 that can fit and rotate with the outer gear ring 17 is rotatably connected to the outer wall of the threaded ring 39, and a conveying member 27 for uniform input and output of metal is provided in the body 1.

[0021] The conveying member 27 includes a hopper 28 fixedly mounted on the upper side of the machine body 1, the bottom of the hopper 28 is inclined toward the side of the push block 5 and is connected to the inside of the machine body 1, a rotating column 29 is rotatably connected inside the machine body 1, and a plurality of rotating plates 30 are evenly and fixedly connected to the outer wall of the rotating column 29, one end of the rotating column 29 is coaxially fixedly connected to a second gear 31 meshing with the outer gear ring 17, and a first collecting frame 32 and a second collecting frame 33 are slidably connected to the bottom end of the inner wall of the machine body 1 in a horizontal direction, the first collecting frame 32 is located below the fixed box 26, and is used to collect ferrous magnetic metals, and the second collecting frame 33 is used to collect non-magnetic metals.

[0022] In this embodiment, the outer cylinder 3 is sleeved on the outer wall of the mounting frame 25, and then the magnet 4 is inserted into the position between the mounting frame 25 and the outer cylinder 3, and the threaded ring 39 is screwed on so that the side of the rotating ring 40 fits with the outer gear ring 17. After that, the rotating ring 40 can be driven to rotate synchronously during the rotation of the outer cylinder 3. At the same time, the outer gear ring 17 and the outer cylinder 3 are limitedly installed on the mounting frame 25 together through the rotating ring 40. Conversely, the threaded ring 39 can be rotated in the opposite direction to quickly disassemble, replace, clean, etc. the outer cylinder 3 and the magnet 4.

[0023] The recovered metal to be deironed is crushed into fragments and particles and then input into the feed hopper 28. During the rotation of the outer gear ring 17, the second gear 31 is linked to rotate, so that the rotating column 29 drives the rotating plate 30 to rotate counterclockwise, and the metal at the bottom of the feed hopper 28 is transported to the outer cylinder 3 at the bottom. Since the spacing between the rotating plates 30 is constant and the rotation speed of the rotating plates 30 is constant, the input speed of the metal raw material is more stable, and the outer cylinder 3 rotates clockwise to drive the metal to deflect to the side of the push block 5, and the magnetic metal is adsorbed on the side close to the magnet 4, so as to rotate in contact with the outer wall of the outer cylinder 3, while the metal with weaker magnetism or the non-magnetic metal is thrown out.

[0024] Under the operation of the pushing mechanism, the flying metal is quickly impacted and pushed toward the side wall of the outer tube 3 by the pushing block 5, so as to improve the adsorption efficiency between the metal and the magnet 4, so that some magnetic metals with weak magnetism or thrown out due to inertia can be pushed toward the outer tube 3 and adsorbed by the magnet 4 again; secondly, the metal piled on the surface of the outer tube 3 can be dispersed, and the metal wrapped inside can be separated, so that some non-magnetic metal wrapped inside can be thrown out and fall into the second collection frame 33 for collection, while the magnetic metal will rotate with the outer tube 3 until it is separated from the position where the magnet 4 is adsorbed, and finally fall into the first collection frame 32 for collection.

[0025] The device has a simple structure and is easy to operate. It can achieve multiple collisions between the metal and the outer cylinder 3 when only one set of magnets 4 and the outer cylinder 3 is set, thereby improving the screening efficiency and effectively avoiding the problem of magnetic metal wrapping non-magnetic metal affecting the screening accuracy.

[0026] Example 2: Please refer to Figure 1-Figure 9 This embodiment further illustrates the first embodiment. The pushing mechanism shown in the figure also includes a device box 8 fixedly installed between the two sets of side plates 2. A plurality of sets of sliding grooves 9 are evenly arranged in the device box 8. The pushing block 5 is slidably connected to the inner wall of the sliding groove 9. A tension spring 10 fixedly connected to the sliding groove 9 is fixedly connected to the side of the pushing block 5. A pushing member 11 is provided in the device box 8 for driving the pushing block 5 to slide back and forth during the rotation of the outer cylinder 3.

[0027] The pusher 11 includes a plurality of rotating shafts 12 respectively installed in different device boxes 8, the rotating shafts 12 are rotatably connected to the device boxes 8, a plurality of cams 13 are evenly and fixedly connected to the rotating shafts 12, a plurality of protrusions 14 that can slide in contact with the outer wall of the cam 13 are fixedly connected to the side of the pusher block 5, a transmission wheel 15 is coaxially fixedly connected to one end of the rotating shaft 12, and a transmission member 16 is provided in the body 1 for linking the plurality of transmission wheels 15 to rotate synchronously when the outer cylinder 3 rotates.

[0028] The transmission member 16 includes a guide frame 18 fixedly mounted on the side plate 2, the outer walls of multiple groups of transmission wheels 15 are transmission-connected with a transmission belt 19, the outer wall of the transmission belt 19 is slidingly fitted with the inner wall of the guide frame 18, and any group of transmission wheels 15 is coaxially fixedly connected with a first gear 20 meshing with the outer gear ring 17. A driving member for driving the outer gear ring 17 to rotate is provided in the body 1, and the driving member includes a driving motor 36 fixedly mounted in the fixed box 26. The model of the driving motor 36 is preferably Y80M1-2, and the output end of the driving motor 36 is coaxially fixedly connected with a third gear 37 meshing with the outer gear ring 17.

[0029] In this embodiment, the third gear 37 is driven to rotate by the driving motor 36, so that the outer gear ring 17 drives the outer cylinder 3 to rotate, and the outer cylinder 3 pushes the metal waste to the side of the pushing block 5. The outer gear ring 17 drives the first gear 20 to drive a group of transmission wheels 15 to rotate. The transmission wheel 15 synchronously drives multiple groups of transmission wheels 15 to rotate through the transmission belt 19 set on the outer wall. The transmission belt 19 is limited by the guide frame 18 and can always ensure the synchronous driving of multiple groups of transmission wheels 15 through the internal teeth to avoid slipping. The transmission wheel 15 drives the rotating shaft 12 to rotate, so that the protrusion 14 rotates continuously. The cam 13 hits the protrusion 14 to make the pushing block 5 slide back and forth in the sliding groove 9. The tension spring 10 drives the pushing block 5 to pull back to realize the reciprocating sliding operation of the pushing block 5, wherein the reciprocating state of the multiple groups of pushing blocks 5 can be asynchronous.

[0030] During the reciprocating sliding of the pushing block 5, the top end of the pushing block 5 can hit the metal block splashed from the edge of the outer cylinder 3 to the side of the pushing block 5, causing it to hit the outer wall of the outer cylinder 3 in the opposite direction. This can improve the adsorption efficiency between the metal and the magnet 4, so that some magnetic metals with weaker magnetism or thrown out due to inertia can be pushed to the side of the outer cylinder 3 and the magnet 4 and adsorbed by the magnet 4 again to fit the outer wall of the outer cylinder 3. Secondly, the metal piled on the surface of the outer cylinder 3 can be dispersed, and the metal wrapped inside can be separated, so that some non-magnetic metal wrapped inside can be thrown out and fall into the second collecting frame 33 for collection, while the magnetic metal will rotate with the outer cylinder 3 until it is out of the position where the magnet 4 is adsorbed, and finally fall into the first collecting frame 32 for collection.

[0031] Example 3: Please refer to Figure 1 and Figure 5-Figure 9 The present embodiment further illustrates the first embodiment. The dust removal mechanism shown in the figure also includes a partition plate 21 fixedly installed in the dust removal box 6. A collecting chamber 22 connected to the dust removal box 6 is provided in the device box 8. A plurality of connecting grooves 23 connected to the collecting chamber 22 are evenly provided in the device box 8. The plurality of connecting grooves 23 can be respectively connected to one end of the arc groove 7. A suction piece 24 for sucking dust is provided in the dust removal box 6. The suction piece 24 includes a dust collector 34 fixedly installed in the dust removal box 6. An exhaust grille 35 is fixedly connected to the side of the dust removal box 6.

[0032] In this embodiment, suction is performed by a vacuum cleaner 34 and exhaust is performed from the exhaust grille 35. The dust generated by the mixture of the metal waste inside the body 1 will be directly extracted through the arc groove 7. In the process of the reciprocating sliding of the pushing block 5, the arc groove 7 at the bottom will intermittently slide out of the sliding groove 9 until one end is exposed to the sliding groove 9 and connected to the inside of the body 1, and the other end is connected to the connecting groove 23. At this time, the suction force will draw the dust into the dust removal box 6 through the arc groove 7, the connecting groove 23, and the collecting chamber 22. After being bent and separated by the partition 21, it falls into the dust removal box 6 for filtration and collection, and the filtered gas is discharged through the exhaust grille 35, and the dust is collected in the dust removal box 6.

[0033] Compared with the traditional fixed-position air intake grid, the structure has a more obvious suction effect. On the one hand, the floating dust can be directly sucked away from the arc groove 7 at the bottom from the source position during the reciprocating sliding of the pushing block 5. On the other hand, since the structure of the arc groove 7 and the pushing block 5 is relatively stable, suction is only performed through a single open gap position at one end of the arc groove 7, thereby avoiding the damage to the grid caused by the continuous impact of metal particles. The suction of the arc groove 7 can not only effectively prevent the entry of metal particles, but also withstand the continuous impact of metal particles, and has a longer service life. In order to increase the air intake volume, the traditional air intake grid often adopts a large number of hole designs. Such a setting will reduce its strength, and its service life will be greatly reduced during the continuous impact of particles. The structure is designed with multiple groups of arc grooves 7, which can improve the structural strength while ensuring the air intake volume and extend the service life of the equipment.
