Wet-type strong magnetic separator, by motor (1), reductor (2), crossbeam (3), feedwater feeding system (4), magnetizing coil system (5), mine-carrying groove (6), yoke (7), drainage conduit (8) and by magnetic pole head (17), separation chamber (18), non-magnetic conduction dividing plate (19), iron core (20) and the surface that is distributed in the separation chamber are formed through the separation ring system (11) that the tooth plate (21) of modification processing is formed, it is characterized in that: a magnetizing coil system is by the cooling water tank (14) that has down water inlet (12) and last overfall (13) and be contained in the magnetizing coil (15) through the processing of insulating that being wrapped in the water tank have on the iron core (24) of insulation sleeve (16) and form, the quantity of separation chamber in the b separation ring system, the matching relationship of the thickness of non-magnetic conduction dividing plate and magnetic pole cornerite is: the sorting number of chambers is an odd number, the average thickness of non-magnetic conduction dividing plate is 1/4 of separation chamber's length, the magnetic pole wrap angle sigma
1Numerical value be the angle α of separation chamber
21/4 times again of N (N is a positive integer), and magnetic pole head shrinkage ratio is 80～90%, c is that the middle part between bottom yoke and step (10) is provided with magnetism isolating spacer piece (9) in theoretical magnetic zero-bit path.
Have on the non-magnetic conduction dividing plate in the separation ring system with dividing plate be being used for fixing of one and the flange (23) that separation chamber's cover plate is played position-limiting action.
When the wet high-intensity magnetic machine is worked, the magnetizing coil energising back that is enclosed within the coil system on the yoke produces magnetic field, form magnetic loop through yoke and separation ring system, thereby between the tooth plate medium of separation ring, produce induced field, motor via reducer drives the separation ring system and rotates, the feedwater feeding system feeds ore pulp in the separation chamber of separation ring system in magnetic field, be distributed in the tooth plate medium gap, the magnetic ore particle is magnetized collecting on medium, non-magnetic ore particle then flows out from the medium gap and is collected in the non magnetic of mine-carrying groove and connects in the mining area, ore particle by collecting travels forward with separation ring, in magnetic field, be subjected to the rinsing of washings, the weak lean intergrowth of non magnetic ore particle that part is mingled with and magnetic pole connects in the mining area as the chats that chats enters mine-carrying groove, magnetic mineral after the rinsing goes to the differential gap with separation ring, induced field between medium disappears, concentrate breaks away from the magnetic mineral that medium enters mine-carrying groove and connects in the mining area under the flushing of water under high pressure, mine-carrying groove is with magnetic mineral, chats, three kinds of products of non magnetic ore are discharged respectively by drainage conduit, so far finish one and sort purification process.
Because the magnetizing coil system coil of Wet-type strong magnetic separator of the present utility model adopts water to cool off outward, can directly absorb the heat of magnetizing coil electric energy conversion, the flow of control cooling water can be controlled at coil temperature rise in 30 ℃, make intensity magnetic separator of the present utility model under specified exciting curent, has the lower temperature liter, saved electric energy loss greatly, the coil system volume is reduced.The optimum Match of the quantity of separation chamber, magnetic pole cornerite and non-magnetic conduction block board thickness, each moment that separation ring is rotated all has and has only a dividing plate to enter or breaks away from field regions, the defining flange of dividing plate has been eliminated the play of separation chamber's cover plate (22) along garden Zhou Fangxiang, guarantee the separation ring running steadily, effectively the life-span of the long equipment in edge.The reasonable shrinkage ratio of magnetic pole head has reduced leakage magnetic flux effectively, has improved and has given mining area magnetic induction intensity, has improved the working area field unevenness.Theoretical magnetic zero-bit path is provided with the magnetism isolating spacer piece, prevents to produce the possibility that invalid magnetic loop and transmission system are magnetized, and improves the sorting index and the efficient of mineral effectively, and ductility has been grown equipment life.
