Description
Technical field
The utility model belongs to ore-dressing practice technical field, is specifically related to a kind of copper smelting-furnace slag recovery system.
Background technology
Cyclone is as a kind of common separation classifying equipoment, and its operation principle is centrifugal sedimentation, and it is by having the liquid-liquid of certain density contrast, liquid-solid, and two-phase or multiphase mixture such as liquid-gas separates under the effect of centrifugal force.When two-phase to be separated or three-phase mixed liquor tangentially enter in cyclone with certain pressure from cyclone periphery, produce the strong rotational shear turbulent motion of strong Three-Dimensional Elliptic, owing to existing the poor or density contrast of granularity between coarse granule (heavy phase) and fine grained (light phase), its centrifugal force being subject to, centripetal buoyancy, fluid drag force etc. vary in size, be subject to centrifugal sedimentation effect, most crude particle (heavy phase) is discharged through cyclone underflow opening, and most of fine grained (light phase) is discharged by overflow pipe, thereby reach the object that separates classification.But in practical operation, the obstruction of cyclone charging aperture can make overflow and sand setting flow reduce, and the obstruction of hydrocyclone sand mouth can make sand setting flow reduce even to stop, and strenuous vibration also can occur sometimes.As stop up, should close in time cyclone feed valve, remove tamper.And separating effect is not very desirable.
Prior art is generally used single cyclone in copper smelting-furnace slag recovery system, and the secondary ore pulp that it carries out after classification one section of ball milling ore pulp carries out thickness separation, and the thick two sections of ball mills that enter into grind again, to reach the needed fineness of flotation.In secondary ore pulp separates, existing most of producers are all continuing to use large specification cyclone, and operating efficiency is not high, separate and do not reach desirable requirement.
Utility model content
The purpose of this utility model is for a kind of copper smelting-furnace slag recovery system is provided, and to solve, the single cyclone operating efficiency existing in prior art is not high, separation does not reach the desirable technical problem requiring.
In order to achieve the above object, the utility model is by the following technical solutions: a kind of copper smelting-furnace slag recovery system, comprise one section of ball mill, the gape of described one section of ball mill is provided with ore discharge spill box, described ore discharge spill box connects sand pump pond, described sand pump pond connects respectively the entrance of the each cyclone in a cluster cyclone by sand pump, the outlet at bottom of the each cyclone in described a cluster cyclone is connected with the feed port of two sections of ball mills respectively, and the overfall of the each cyclone in described a cluster cyclone is connected with two sections of sand pump ponds.
As further improvement of the utility model, described a cluster cyclone comprises 4 cyclones.
As further improvement of the utility model, described a cluster cyclone comprises 6 cyclones.
As further improvement of the utility model, the diameter of the each cyclone in described a cluster cyclone is 100mm.
The relative prior art of the utility model has following beneficial effect: the utility model arranges a cluster cyclone in copper smelting-furnace slag removal process, mixed liquor to be separated tangentially enters the cyclone of multiple small dimensions with certain pressure, make overflow bore less, in the situation that bulk flow does not reduce, ore pulp produces High Rotation Speed flow field in cylindrical cavity, the component that in mixed liquor, density is large moves downward vertically simultaneously under the effect of eddy flow field, radially outwards motion, move downward along wall in arrival cone segments, and discharged by outlet at bottom, so just form outer swirling flow field, the component that density is little is moved to central axial direction, and form an inside vortex moving upward in axis centre, then discharged by overfall, two objects that are separated are so just reached, operating efficiency is high, separating effect ideal.Four or six ￠ 100 cyclones of the utility model employing are replaced ￠ 250 cyclones in existing copper smelted furnace cinder recovery systems, one of them is as for subsequent use, original spillway discharge is not reduced, eddy flow sorts ore pulp 74um fineness and brings up to more than 75% by original 60%; rough after two sections of ball mill ore grindings after sorting; ore pulp 74um fineness is brought up to more than 93% by original 85%, for good condition has been created in flotation.
