Abstract
The utility model discloses a protection device for a dry type classificator. The protection device comprises a magnetic induction roller having the two ends supported on a bearing support and made of magnetic conducting material; a material guide groove is formed below the magnetic induction roller; a conveying helix piece is mounted in the material guide groove; and one end of the conveying helix piece is connected with a reducing motor, and an ore discharge opening is formed below the other end. When the dry type classificator adopts the device, ore that is sucked mistakenly can be discharged effectively, the situation that ore is clamped between a magnetic drum and a belt as equipment runs to cause serious damage to the drum and the belt is avoided, so that the service life is prolonged, and the maintenance cost is lowered. After the dry type classificator adopts the device, the service lives of the drum and the belt are prolonged from the original 1 to 2 months to over 6 months and is increased by over 3 times, so that the economic benefits can be improved.
Description
One, technical field
The utility model belongs to magnetic separator part technical field, is specifically related to a kind of dry type refiner and uses protective device.
Two, background technology
The dry type refiner is the capital equipment that iron mine beneficiation factory carries out preliminary election to ore, is mainly reached around the belt of their rotations by magnet drum, cylinder to constitute.It generally is positioned at mill in beneficiation flowsheet before, can effectively reclaim the magnetic ore deposit, the barren rock of dishing out, the production efficiency of raising ball mill reduces beneficiation cost.The magnetic system of this machine is the revolving magnetic system that is installed in the inside of magnet drum, and its direction of rotation and magnet drum are opposite, and adopts the design of the full magnetic of many magnetic poles system.Can be in the magnetic field that high-frequency replaces when ore is flowed through the belt surface of revolving magnetic system repeatedly counter-rotating, jump fast; Make magnetic ore and non magnetic ore high efficiency separation; Magnetic ore is attached to belt surface when being brought to the no magnetic area of bottom, under the deadweight effect, drops to the concentrate mouth and discharges.And non magnetic assorted stone is discharged from the mine tailing mouth freely through the magnetic separation district.Owing to be full magnetic architecture; In process of production; Have the part ore and inhale on the magnet drum surface, and, cylinder and belt are caused serious damage along with the running of equipment is clipped between magnet drum and the belt because of the sealing failure gets into mistake from the belt side; Reduce service life, increased maintenance cost.
Three, summary of the invention
The purpose of the utility model provides a kind of dry type refiner and uses protective device, can avoid mistake to inhale the damage of ore to magnet drum and belt effectively, increases the service life, and reduces maintenance cost.
Be to realize above-mentioned purpose, the technical scheme that the utility model adopts is: this device comprises two end supports magnetic induction roller on bearing block, that processed by permeability magnetic material; Be characterized in: below the magnetic induction roller, be provided with deflector chute, the conveyor screw sheet is installed in this deflector chute, an end of conveyor screw sheet links to each other with reducing motor, and the below of the other end is provided with gape.
During use,, make the surface of the surface of magnetic induction roller near the magnet drum middle part with the middle part, space that the utility model places dry type refiner belt to center on.Because the magnetic induction roller is processed by permeability magnetic material, the magnetic field greater than the magnet drum surface can be sensed in its surface, the lip-deep mistake of magnet drum is inhaled ore be adsorbed onto on it.Simultaneously, the magnetic induction roller can be under the effect of alternating magnetic field power at dry type refiner magnetic, do opposite with magnetic system, with magnet drum rotation in the same way; Mistake is inhaled ore take position to away from magnet drum; Because away from magnetic field, the magnetic force on magnetic induction roller surface also can be along with weakening disappearance, the mistake that is adsorbed is up inhaled ore can break away from the magnetic induction roller; Drop in the deflector chute, by the conveyor screw sheet in the deflector chute from the gape device for transferring.Because mistake is inhaled ore and is discharged from, and can not be clipped in along with the running of equipment between magnet drum and the belt, and cylinder and belt are caused serious damage, has prolonged service life, has reduced maintenance cost.The dry type refiner adopts this protective device, and the life-span of cylinder and belt was increased to more than 6 by original 1-2 month, had improved more than 3 times, had increased economic benefit.
Four, description of drawings
Fig. 1 is the structural representation of the utility model;
Fig. 2 is the user mode figure of the utility model.
Five, the specific embodiment
As shown in Figure 1, the utility model comprise two end supports on bearing block 1, by the magnetic induction roller 2 that permeability magnetic material is processed, the outer surface of this magnetic induction roller 2 is provided with can increase the inductive spiral of magnetic induction sheet 12.Below magnetic induction roller 2, be provided with the deflector chute 4 that has baffle plate 13.Conveyor screw sheet 3 is installed in the deflector chute 4, and an end of conveyor screw sheet 3 links to each other with reducing motor 5, and by reducing motor 5 driven in rotation; The below of the other end is provided with and is used to discharge the gape 6 that mistake is inhaled ore.Above-mentioned bearing block 1 is fixed on the two ends of deflector chute 4 through support 7, and deflector chute 4 is supported by frame 14.As shown in Figure 2, during use, place dry type refiner belt 10 around cylinder 11 middle part, space that 8 rotations form with magnet drum the utility model, the surface that makes magnetic induction roller 2 is near being built-in with the surface that magnetic is 9 magnet drum 8 middle parts.Distance between magnetic induction roller 2 and the magnet drum 8 is that 5-8mm gets final product.
Claims (2)
