Abstract
The utility model discloses an aerated hydraulic cyclone for controlling high density useful mineral substance from over-grinding. The utility model is composed of a feed inlet, an overflow pipe, a feed chamber, a multi-hole device wall, a clamping sleeve, a bottom flow cone and a baffle plate. The upper part of the feed chamber is provided with the feed inlet, and the feed inlet is communicated with the feed chamber along the tangent direction. The top center of the cyclone is provided with the overflow pipe, and the multi-hole device wall is arranged between the bottom flow cone and the feed chamber. The exterior of the multi-hole device wall is provided with the clamping sleeve which is provided with a plurality of air inlet nozzles, and the interior of the bottom flow cone is provided with the baffle plate. The utility model can control the high density useful mineral substance from over-grinding, improve recovery ratio of useful minerals and reduce the total grinding energy consumption.
Description
The utility model relates to the Mineral Classification technology, particularly a kind of overground inflation hydrocyclone of big density valuable mineral of controlling.
At present, in the classifying equipoment of grinding classification system, all are density and the granularities that rely on particle, by waiting relation of falling to carry out classification.The ore particle that contains two or more density material by the result of this classifying by equal falling is: the big large diameter underflow that enters of density, little density minor diameter enter overflow; Little density is large diameter to be had part to enter underflow another part then can to enter overflow; Big density minor diameter also have part to advance underflow partly to enter overflow; The partition size that is big density material is littler than the partition size of little density material.The efficient of this classification is not high, and its shortcoming is: have many bulky grains (mainly being little density) to sneak in the overflow, have many granules (mainly being big density) to sneak in the underflow.And sneak in the big density granule in the underflow many monomer dissociations that reached are arranged, and its granularity has been suitable for follow-up sorting operation,, will inevitably have caused the overground of these mineral if these particles are returned grinding machine to be regrinded.In metal mine, big density mostly be valuable mineral.Valuable mineral overground at first can cause the grinding machine circulating load to increase, and total productive capacity descends, and energy consumption increases; Secondly, the overground meeting of valuable mineral causes the argillization of valuable mineral, and is unfavorable to follow-up sorting operation, and the microfine valuable mineral is run off, and causes the overall recovery of valuable mineral to reduce, and not only wastes energy but also waste resource, and the ore dressing plant economic benefit is descended.And existing hydrocyclone can't address this problem.
In view of the deficiency that prior art exists, the purpose of this utility model provides a kind of simple in structure, can control the overground inflation hydrocyclone of big density valuable mineral effectively.
For achieving the above object, the utility model is achieved through the following technical solutions.
The inflation hydrocyclone comprises charging aperture, overflow pipe, feed space, underflow awl, charging aperture is established on feed space top, charging aperture tangentially connects with feed space, establish an overflow pipe in the cyclone center of top, it is characterized in that: between feed space and underflow awl, establish a porous wall of making by porous media, establish a chuck in the outside of porous wall, on chuck, establish a plurality of suction nozzles, establish a baffle plate in underflow awl inside.
The utility model compared with prior art has the following advantages:
Owing to, can control and avoid the overground of big density valuable mineral, thereby improve the rate of recovery of valuable mineral by the classification of this cyclone inside and the acting in conjunction of flotation, reduce the mineral resources waste, reduced the total energy consumption of ore grinding.Therefore, be specially adapted to the grind grading of the valuable mineral density material bigger than gangue mineral density.
Embodiment is further described the utility model below in conjunction with accompanying drawing.
The inflation waterpower hydrocyclone structure cutaway view that Fig. 1 provides for the utility model.
The vertical view of the inflation hydrocyclone that Fig. 2 provides for the utility model.
From Fig. 1,2 as can be seen, the inflation hydrocyclone is made up of charging aperture 1, overflow pipe 2, feed space 3, porous wall 4, chuck 5, baffle plate 7, underflow awl 8, charging aperture is established on the top of feed space, charging aperture tangentially connects with feed space, establish an overflow pipe in the center of top of cyclone, underflow awl is established in the bottom of cyclone, establishes a porous wall between feed space and underflow awl, and it is made by porous media.Establish a chuck in the outside of porous wall, on chuck, establish a plurality of suction nozzles 6, establish a baffle plate 7 in underflow awl inside.Baffle plate plays and prevents that foam from entering the effect of underflow, makes classification performance more reliable and more stable.
When the work of inflation hydrocyclone, at first in material, add an amount of floating agent, big density valuable mineral particle surface is than strong-hydrophobicity, the material that mixed with floating agent is entered in the cyclone by the tangential direction of charging aperture along feed space, bigger particle enters in the outer eddy flow of close limit wall in the material, and sedimentation under the screw, is discharged by the underflow awl at last, smaller particles then enters overflow in the material, is discharged by overflow pipe.During work, in chuck, constantly charge into gases at high pressure by suction nozzle, gases at high pressure enter cyclone inside through the porous wall, form a large amount of tiny bubbles at porous wall inner surface, in cyclone along periphery be rotated down the ore particle that moves constantly and bubble collide, the surface is hydrophobic ore particle then will together form mineral laden bubble with bubble, so the surface is hydrophobic big density valuable mineral particle and just can carries out classifying by equal falling by the density and the granularity of mineral laden bubble, and no longer is to have been undertaken by the density and the granularity of mineral grain self.Obviously, the density of mineral laden bubble is more much smaller than the density of appended ore particle itself, so, those will enter the less big density valuable mineral of particle of underflow in common hydrocyclone, in the inflation hydrocyclone, then can form mineral laden bubble because of adhering to bubble, and will enter overflow at last, thereby avoided the ore particle of these big density valuable minerals be returned grinding machine regrind and cause overground.
