Description

Technical Field

[0001] The utility model relates to the technical field of magnetic separators, and in particular to a waste circuit board recycling magnetic separator capable of replacing magnets with different magnetic forces. Background Art

[0002] Magnetic separator is a screening device used to remove iron powder from recycled powder particles. After the slurry flows into the tank through the feed box, the ore particles enter the feeding area of ​​the tank in a loose state under the action of the water flow of the feed water pipe. Under the action of the magnetic field, the magnetic ore particles are magnetically gathered to form "magnetic clusters" or "magnetic chains". The "magnetic clusters" or "magnetic chains" are affected by the magnetic force in the slurry and move toward the magnetic poles and are adsorbed on the cylinder. Since the polarity of the magnetic poles is arranged alternately along the rotation direction of the cylinder and is fixed during operation, the "magnetic clusters" or "magnetic chains" produce magnetic stirring due to the alternation of magnetic poles when the "magnetic clusters" or "magnetic chains" rotate with the cylinder. Non-magnetic minerals such as gangue mixed in the "magnetic clusters" or "magnetic chains" fall off during the turning, and the "magnetic clusters" or "magnetic chains" that are finally adsorbed on the surface of the cylinder are the concentrates.

The card grooves 4 are used to place round blocks 12, that is, to connect the main barrel 1 and the auxiliary barrel 2.

[0031] In this embodiment, two groups of round blocks 12 are fixedly provided at one end of the auxiliary barrel 2, and the round blocks 12 are correspondingly engaged with the slots 4. The existence of the round blocks 12 and the slots 4 can connect and engage the main barrel 1 and the auxiliary barrel 2 with each other.

[0032] In this embodiment, a third groove 9 is formed on the inner wall of the second annular groove 8 . The third groove 9 is communicated with the first annular groove 5 . The second annular groove 8 is used to place the first ring block 13 .

[0033] In this embodiment, a fourth groove 10 is formed on the outer surface of the auxiliary tank barrel 2 , and the fourth groove 10 is connected to the second groove 6 . The existence of the fourth groove 10 allows the second ring block 16 to slide freely along the fourth groove 10 .

[0034] In this embodiment, two groups of first protrusions 14 are fixedly provided on the outer surface of the first ring block 13 , and the first protrusions 14 are movably connected to the third groove 9 and the first ring groove 5 respectively.

[0036] During use, when it is necessary to replace the magnetic separator with a different magnetic magnet, the staff first needs to take out the magnetic separator, and then the staff needs to take out the round block 12 from the inside of the card slot 4, that is, to separate the main box barrel 1 and the auxiliary box barrel 2 from each other. At this time, the auxiliary box barrel 2 can be placed on one side, and then the staff pulls the first ring block 13 to move the first ring block 13 along the second groove 6 until the first protrusion 14 is disengaged from the second groove 6, and the first ring block 13 can be removed from the inside of the main box barrel 1 and the auxiliary box barrel 2, and then another set of different The first ring block 13 is replaced on the inner wall of the second ring groove 8, and the first protrusion 14 is aligned with the second groove 6. Then the third groove 9 of the auxiliary barrel 2 is attached to the first protrusion 14. The auxiliary barrel 2 is continuously moved to place the round block 12 inside the card groove 4 until the main barrel 1 and the auxiliary barrel 2 are fitted together. At this time, the first ring groove 5 and the second ring groove 8 are completely fitted with the first ring block 13. At this time, the replacement of different magnetic magnets can be completed, so that the first ring block 13 can be simply fixed to facilitate the replacement of different magnetic magnets.

[0041] In this embodiment, the clamping block 19 is movably connected and engaged with the first circular groove 3 and the second circular groove 11 respectively. The mutual engagement between the clamping block 19 and the first circular groove 3 can prevent the second ring block 16 from continuing to move.

[0042] When the staff needs to replace different magnetic magnets on the magnetic separator for fixing, the staff first needs to replace the magnetic magnets, first take out the clamping block 19 from the inside of the second circular groove 11, and after connecting the main barrel 1 and the auxiliary barrel 2, the staff pushes the second ring block 16 to move along the fourth groove 10 until the second ring block 16 and the first groove 7 fit each other, and then place the clamping block 19 inside the first circular groove 3, and the connecting rope 18 is in a taut state at this time. At this time, the second ring block 16 can fix the main barrel 1 and the auxiliary barrel 2, so as to facilitate the work of quickly fixing the magnetic separator after replacing different magnetic magnets, eliminating the labor steps of the staff.
