Abstract
The utility model discloses an ore unloading magnetic induction roller. The ore unloading magnetic induction roller comprises a main roller, two ends of the main roller are supported on a bearing support, and the main roller is driven by a motor to rotate and is a magnetic induction roller made of magnetic conducting material. When being used, the ore unloading magnetic induction roller is placed at the ore unloading port of a wet-type magnetic separator near to a rotary drum, and the main roller is driven by the motor to perform the high-speed rotation in the direction opposite to the rotation direction of the rotary drum. Since the main roller is a magnetic induction roller, the surface of the main roller near to a magnetic system can induct a magnetic field larger than that on the surface of the rotary drum and can adsorb magnetic materials on the main roller. The adsorbed magnetic materials are unloaded under the centrifugal force generated by the high speed rotation of the main roller after getting away from the magnetic system along with the rotation of the main roller. Substantially, the ore slurry unloaded from the ore unloading port of the wet-type magnetic separator is separated secondarily to realize radical ore unloading. The utility model not only greatly improves the iron removal effect, but also has the advantages of simple structure, reasonable design, and so on, and fills the gap in the type of magnetic separator parts, thereby being worthy of wide popularization.
Description
One, technical field
The utility model belongs to magnetic separator part technical field, is specifically related to a kind of wet magnetic separator with unloading ore deposit magnetic induction roller.
Two, background technology
Wet magnetic separator is a kind of iron ore beneficiation equipment, also is used for the deironing operation of non-iron mineral simultaneously, like the deironing of quartz sand ore, and the deironing of tantalum niobium concentrate etc.Usually the cylinder and the cell body that have a magnetic system by inside constitute, and crouch in cell body in the bottom of cylinder, and the two ends of cell body and lower end are respectively equipped with into, gape and debris tube.Its operation principle is that to utilize magnetic be that the running of magnetic field effect and cylinder sorts the magnetic thing in the ore pulp out, reaches the purpose of ore dressing or deironing.Generally speaking; It is when rotary drum brings out magnetic mineral continuously that the concentrate of magnetic separator unloads the ore deposit process; Utilize follow-up concentrate to promote the concentrate of front; The concentrate of front is pushed away field region, reach the effect that nature unloads the ore deposit, utilization is simultaneously unloaded ore deposit bath effect the glutinous concentrate of being with of cylinder surface is washed.But the deironing operation of using in non-iron ore industry is because iron-holder is very little in the ore pulp; Be generally 0.1%-1%, it is very few to unload the magnetic material that ore deposit process intermediate roll brings out at magnetic separator, does not reach the ore deposit, back and does not push away the effect in preceding ore deposit; Therefore it is all bad generally to unload the ore deposit effect, and iron can circulate in magnetic separator always, and row does not come out; Cause a part of iron to turn back to again in the material, de-ferrous effect is undesirable.
Three, summary of the invention
The purpose of the utility model provide a kind of can effectively improve the wet magnetic separator de-ferrous effect unload ore deposit magnetic induction roller.
For realizing above-mentioned purpose, the utility model adopts technical scheme to be: this induction roller comprises that two end supports on bearing block, by the home roll that motor-driven is rotated, is characterized in: the magnetic induction roller of described home roll for being processed by permeability magnetic material.
During use, the utility model is placed on the wet magnetic separator ore discharging port near the cylinder place, and by the high speed rotating of driven by motor home roll work with the cylinder direction of rotation.Because home roll is the magnetic induction roller, the magnetic field greater than cylinder surface can be sensed near magnetic system place in its surface, and magnetic material is adsorbed onto on it.The magnetic material that is adsorbed along with the rotation of home roll away from magnetic system after, rotate discharging under the action of centrifugal force of generation at a high speed at home roll.The essence of the utility model is that the ore pulp from the discharging of wet magnetic separator ore discharging port is carried out the secondary sorting; Thereby realize thoroughly unloading the purpose in ore deposit; It has not only improved de-ferrous effect greatly; Also have advantages such as simple in structure, reasonable in design, replenished the blank of this type of magnetic separator part, be worth applying widely.
Four, description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the working state figure of the utility model.
Five, the specific embodiment
As shown in Figure 1, the utility model comprises that two end supports drives the home roll 2 of rotation on bearing block 1, by motor 4.The magnetic induction roller of main shaft 2 for processing by permeability magnetic material; Its surface is provided with trapezoidal thread 12; This trapezoidal thread 12 can reduce induction areas, makes induced field more concentrated, can produce very strong magnetic field in the crest portion of trapezoidal thread silk 12; Increase the induced field intensity of home roll 2, more help the absorption of magnetic material.Motor 4 is connected with home roll 2 through shaft coupling 3, and it can be speed adjustable range is 100-200 rev/min buncher, can reach through speed governing to make mineral of different nature reach centrifugal effect of unloading the ore deposit.
As shown in Figure 2; The utility model is used on the wet magnetic separator 6; It is that 7 cylinder 5 constitutes with cell body that this wet magnetic separator 6 has magnetic by inside, crouches in cell body 8 in the bottom of cylinder 5, and the two ends of cell body 8 and lower end are respectively equipped with into, gape 9,11 and debris tube 10.During use, the utility model is placed on the ore discharging port 11 of wet magnetic separator 6 near cylinder 5 places, and distance is 5-8mm between home roll 2 surfaces and cylinder 5 surfaces.
