The specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only a part of embodiment of the present invention, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making under the creative work prerequisite the every other embodiment obtained, belong to the scope of protection of the invention.
Fig. 1-2 is depicted as the electric anode of erosion, and Fig. 3-5 are depicted as magnetic medium box.In Fig. 6-11, the concrete indication of Reference numeral is as follows: 1, lose electric anode, 2, magnetic medium box, 3, electrodeposited coating, 4, the anticorrosion magnetic medium box of Verticle ring high intensity magnetic separator, 5, change, 6, coil, 7, the case of pulsing.
Specifically with reference to shown in Figure 11, high-gradient magnetic separation is the high-gradient magnetic field that utilizes magnetic medium box to produce in magnetic field and utilizes this high-gradient magnetic field to reclaim the magnetic plant of weak magnetic mineral, and this equipment magnetic medium box has very strong capturing ability to weak magnetic mineral.The magnetic medium box be arranged in change rotates with change, after catching weak magnetic mineral, the background magnetic field district produces field regions to unloading mining area, now background magnetic field disappears, and the induced field that magnetic medium box produces disappears thereupon, and the magnetic material before caught washes away arrival magnetic ore deposit collecting region with unloading mineral water.
In the present invention, Verticle ring high intensity magnetic separator with anticorrosion magnetic medium box by magnetic medium box as skeleton, the material of magnetic medium box is to take the magnetic stainless steel (such as relevant materials such as 0Cr13) that iron is matrix, Verticle ring high intensity magnetic separator with on anticorrosion magnetic medium box, inlay a kind of metal activity higher than the metal material of ferrous metal as the electric anode of erosion.As shown in Figure 1-2, anticorrosion magnetic medium box is rectangle structure to its shape, and its material is zine plate or aluminium sheet, also the metal activity relevant materials active higher than ferrous metal; Lose electric anode and penetrate magnetic medium box, remain on a horizontal plane and with the magnetic medium box end face and fully contact with the end face of magnetic medium box, Verticle ring high intensity magnetic separator is comprised of six electric anodes of erosion altogether with anticorrosion magnetic medium box, inlays position in the uniform arrangement in the center of magnetic medium box end face.
As shown in the figure, the present invention inlays or welds the electric anode 1 of erosion on magnetic medium box 2, welds or be embedded in the erosion electricity anode 1 in magnetic medium box 2, the electric charge in ore pulp can be transferred on the electric anode 1 of erosion.
Verticle ring high intensity magnetic separator in the present invention is by change, the anticorrosion magnetic medium box of Verticle ring high intensity magnetic separator, and yoke, magnet exciting coil, pulsing mechanism, unload mineral water, and various receiving hoppers and support form.In use, at first change is rotated, and the anticorrosion cartridge of chromium stainless steel of the low remanent magnetism of high magnetic flux density is housed in ring.The magnetizing mediums of anticorrosion cartridge induces very strong induced field in background magnetic field, and by high-intensity magnetic field, magnetic-particle is caught, thereby realizes separating of magnetic-particle and non-magnetic particle.
The specific works process is, the raw material ore pulp fed is entered by ore inlet port, gap through between upper magnetic pole yoke plate flows into the sorting zone, magnetizing mediums in the change of minute favored area is magnetized in very strong background magnetic field, the magnetizing mediums surface produces the high field region of a gradient, ore pulp effect magnetic particle at magnetic field force when flowing through this field region will be adsorbed on the magnetizing mediums surface, and be taken out of a minute favored area with change.Because magnetizing mediums remanent magnetism is extremely low, therefore after leaving magnetic field minute favored area, this high gradient induced field zone on its surface just rapidly disappears, the magnetic field force that now catches magnetic-particle is also vanished from sight thereupon, magnetic-particle in succession comes off and flows in magnetic material collection all, unload mineral water when magnetizing mediums turns over top remaining magnetic-particle is also poured in the magnetic material collection bucket, all magnetic-particles finally come together in magnetic material and gather in bucket and discharged by the magnetic material mouth.The non-magnetic particle be not adsorbed through magnetizing mediums, in the lower yoke of flowing through by magnetizing mediums and a minute favored area, is finally discharged by the non-magnetic material outlet.
If give in ore deposit, have bulky grain can not pass magnetic medium box, generally can rest on the upper surface of cartridge, near the change inner periphery, when magnetic medium box is taken to top by change, just in time rotated 180 degree, bulky grain is positioned at the bottom of magnetizing mediums, directly discharges.
When eardrum is reciprocating under the driving of pulsion stroke case, as long as the magnetizing mediums of mineral syrup liquid height energy submergence change bottom, the ore pulp of separation chamber pumps, Pulsating Flow muscle power makes mine particle group remain loose condition (of surface) in assorting room, thereby effectively eliminated the mechanical entrainment of non-magnetic particle, improved significantly the grade of magnetic concentrate.In addition, the ore pulp pulsation is obviously also very beneficial to the obstruction that prevents magnetizing mediums.The reciprocating speed of eardrum can be regulated by the motor by Frequency Converter Control.The reciprocating speed of eardrum is regulated the sorting that can better adapt to various materials.Make sorting reach optimum efficiency.
Change vertical rotating in whole assorting room, can guarantee that the inflow of ore pulp and the final ore deposit of unloading put even change inner periphery, thereby make can't be by magnetizing mediums the coarse granule material be washed into the magnetic material collection bucket going to change when the mineral water place is unloaded at top, can not stop up magnetizing mediums.Verticle ring high intensity magnetic separator is fixed in change with anticorrosion magnetic medium box, and change is installed in Verticle ring high intensity magnetic separator.
The cartridge supported on both sides adopts the clamp lug structure, when the dismounting magnetizing mediums, can can't not pull down because deformation of media is stuck in change cartridge.Fixed bolt hole on the change skeleton adopts American Standard (U.S.) #MIL-N-85353～85353/2A retaining screw thread, set bolt employing GB/T5783-2000 high accuracy non-magnetic stainless steel bolt of intensity more than 8.8 grades, can effectively prevent coming off of cartridge set bolt.
The pulsation case is by pulse motor belt drives pulsation case, and the big belt pulley rotation on the case that makes to pulse, rotate thereby drive driving shaft in casing, and connecting rod couples together with the push-rod handle that is connected the other end by bearing pin with active eccentric shaft one end.Push-rod handle and slide block can be done straight reciprocating motion on guide rail.Push-rod handle drives push rod and moves reciprocatingly.Final push rod drives eardrum and moves reciprocatingly.Thereby realize the pulsion stroke motion.In assorting room, the pulsation case drives the rubber eardrum to treat sorting material always and applies pulsation thrust, make to treat in assorting room all in loose condition (of surface), thereby effectively reduce the mechanical entrainment of non-magnetic particle, improved the purity of magnetic-particle, reduced magnetizing mediums and divided the obstruction of choosing.
Magnet exciting coil is sandwich construction, disk-type winding by the measure-alike single rectangular ring of multilayer length and width forms, every layer cake formula coil is formed by the coiling of multiturn electromagnetic wire, the electromagnetic wire of disk-type winding is arranged in the Stainless Steel Shell of sealing, electromagnetic wire outer wrap multi layer cloud motherboard, the gap location wrap insulate layer of micarex and Stainless Steel Shell.The measure-alike disk-type winding of multilayer length and width respectively along the coil outer and interior edge arrange and weld together with order up and down, form whole magnet exciting coil.Between two adjacent disk-type windings, by the formation of water channel back-up ring is set, can, by the gap of cooling water, be cooling water channel, for passing through of cooling water.Produce magnetic field after the magnet exciting coil energising, change is rotated therein, and the Verticle ring high intensity magnetic separator be arranged in change is magnetized in background magnetic field with anticorrosion magnetic medium box, and the magnetizing mediums surface forms the high magnetic field of gradient, thus the absorption material.
Because Verticle ring high intensity magnetic separator in whole assorting room is the core component of complete equipment with anticorrosion magnetic medium box, the quality of cartridge design, corrosion-resistant degree direct influence mineral processing index.
As need are further strengthened the corrosion resistant performance of cartridge, specious, also can, before not inserting the metal material of activity higher than ferrous metal, at all surface of magnetic medium box, electroplate one deck corrosion resistant film.So just can increase whole wear-resistant and resistance to corrosion, increase the service life.
