Abstract
The utility model discloses a forward flow type permanent magnetism drum magnetic separator of constant height of ore pulp liquid level. In the utility model, one side which is adjacent to a concentrate port of a groove (8) is provided with a tailing port. The pulp liquid level height in the groove is constant and the separating index is stable, and the utility model has the advantages of simple structure, easy fabrication, low cost, convenient operation, etc. The utility model can be widely used for the separation of magnetic minerals and non-magnetic minerals in black and nonferrous metal separating plants, heavy medium coal separating plants, etc.
Description
The utility model belongs to a kind of downstream-type permanent-magnet drum type magnetic separator, can be widely used in separating of magnetic mineral such as black, non-ferrous metal ore factory and hm coal preparation plant and non magnetic ore, and is particularly suitable to Benefication of magnetite.
At present, magneticore-dressing plant is used to sort the preparation equipment of strongly magnetic mineral, mostly is permanent-magnet drum type magnetic separator.Permanent-magnet drum type magnetic separator is according to its trough body structure pattern difference, can be divided into three kinds of downstream-type, adverse current type and half adverse current types.The trough body structure of downstream-type permanent-magnet drum type magnetic separator is a downstream-type, and promptly the direction of rotation of the mobile aspect of giving ore deposit direction, magnetic product, non-magnetic product of magnetic separator and cylinder is consistent.The downstream-type magnetic separator has sorting coarse size, concentrate grade advantages of higher." mine " magazine o. 11th had been done introduction to the 167-C9 of former Soviet Union type downstream-type permanent-magnet drum type magnetic separator in 1961.This magnetic separator mainly partly is made up of magnetic system, cylinder, cell body etc., and its cell body is a double-decker, and inside and outside layer communicates by the mine tailing mouth, is provided with valve on the debris tube of outer bottom, and side is provided with overfall and links to each other with overflow pipe.The subject matter that this magnetic separator exists is that when mine-supplying quantity fluctuateed, the mineral syrup liquid height changed thereupon in the cell body, must keep the operating fluid level of ore pulp by control valve, operates very inconvenient.Otherwise will cause the tailings grade height, the magnetic mineral loss is big.Moreover, the trough body structure relative complex of this magnetic separator has not only increased the difficulty of processing and manufacturing, and has increased the expense of equipment.
The purpose of this utility model is exactly in order to solve above-mentioned problems of the prior art, and a kind of mineral syrup liquid constant height, the simple downstream-type permanent-magnet drum type magnetic separator of trough body structure are provided, and it can make assorting room stable and can reduce equipment cost.
For achieving the above object, the utility model adopts following technical scheme:
The utility model comprises cylinder, magnetic system, cell body etc., is characterized in that cell body is an individual layer, has the mine tailing mouth at cell body near a side of concentrate mouth.
Compared with prior art, the utility model does not change the interior mineral syrup liquid height of magnetic separator cell body owing to adopted technique scheme with the fluctuation of mine-supplying quantity size, and promptly liquid level remains at a correct position, and sorting index is stable, effective.Simultaneously,, thereby simplified trough body structure, reduced equipment cost, and made operation become simple, reduced working strength of workers because cell body is a single layer structure, and has cancelled control valve.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 is a downstream-type permanent-magnet drum type magnetic separator profile in the prior art.
Fig. 2 is the downstream-type permanent-magnet drum type magnetic separator profile of the utility model mineral syrup liquid constant height.
In the utility model profile shown in Figure 2, magnetic separator cell body 8 is a single layer structure, has mine tailing mouth 10 in the side near concentrate mouth 4, and mine tailing mouth 10 communicates with debris tube 9.Ore pulp feeds cell body 8 from feed port 5, at first through dividing constituency 7, then enters concentrate district 6, and the rotation direction of cylinder 1 is consistent with the flow direction of ore pulp.Magnetic is 2 to be fixed in the cylinder.In assorting room, strongly magnetic mineral is adsorbed to cylinder 1 surface and rotates to concentrate mouth 4 with cylinder 1, is discharged by the flushing water effect of wash tub pipe 3; Gangue mineral and weak magnetic mineral can not be adsorbed by magnetic force, flow to mine tailing mouth 10 under the flow of slurry effect in cell body 8, discharge from debris tube 9.In design, the opening length of mine tailing mouth 10 is corresponding with cell body length, and A/F can calculate to determine suitable dimensions according to the size of ore pulp amount.
And in the profile of prior art shown in Figure 1, cell body 8 is a double-decker, and bottom connects debris tube 9, and valve 13 is set on the debris tube 9, and a side that is positioned at concentrate mouth 4 at bottom has overfall 11, and overfall 11 communicates with overflow pipe 12.This version, not only complex structure, processing inconvenience, and when mineral slurry flux changes, lean on control valve 13 to stablize liquid level, complex operation not only, and be easy to cause the fluctuation of mineral syrup liquid height and influence sorting index.
