Background technology
Dark cone concentration basin is made up of columned upper pool body and cone shape lower pool body, and the cone angle of coniform lower pool body is generally between 55 °-60 °, and the height of conical section directly depends on the outside diameter of cone.Utilizing the large cone angle of bottom during concentration and settlement, carry out Compression Settlement to ore pulp, can obtain higher underflow density, is the product that in concentration and settlement, a kind of application is wider, very large in the use amount of China.
But existing product due to shell of column diameter consistent with the outside diameter of cone, concentration basin diameter with highly linear.On-the-spot in use, due to factors such as feed height and human users, the height of concentration basin should not be too high, and the diameter of therefore deeply boring concentration basin is less, and disposal ability is low, can not meet the needs that large-scale mine is produced.For a long time, deep cone thickener can not realize maximizing (diameter large after, highly too large), and its range of application is restricted.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art and a kind of Large deep cone concentration tank is provided, the cylindrical upper pool body of concentration basin does not associate with the diameter of coniform lower pool body, in device height constant or increase less time, the shell of column diameter of equipment can increase greatly, thus add the area of deep cone thickener, improve disposal ability.
The present invention includes cylindrical upper pool body, conical lower pool body, crane span structure, discharge pipeline, crane span structure is across cylindrical upper pool body and be supported on its two ends, top, it is characterized in that: conical lower pool body outside diameter, much smaller than cylindrical upper pool body diameter, connects transition conical tank body between cylindrical upper pool body, conical lower pool body; On crane span structure, cylindrical upper pool body center arranges cloth system, and be made up of distribution barrel upper shell, distribution barrel lower shell, kuppe, distribution barrel upper shell is cylindrical, is positioned at cylindrical upper pool body top; Distribution barrel lower shell is conical, and down, the bottom of cone is positioned at transition conical tank body top to the large end of cone; Kuppe is located at distribution barrel lower shell bottom, is deep in conical lower pool body.
The diameter of described cylindrical upper pool body is determined according to the performance of settling ore pulp, makes the upwelling speed of ore pulp lower than the solid particles sediment speed in ore pulp, realizes, under the disposal ability condition of demand, reaching overflow water water quality requirement.Upper pool body inside is provided with downflow weir.Described conical lower pool body is frustoconical sheets, large end is upper, small end under, cone volume and outside diameter are determined according to the setting condition in the amount of solid in ore pulp and settling property curve required for Compression Settlement, realize the underflow density required for client, its outside diameter is much smaller than cylindrical upper pool body diameter, have nothing to do with upper cylindrical pool body diameter, the direct path correlation of concentration basin height and cylindrical upper pool body is reduced, while realizing area increase, significantly reduce the degree of depth of cone segments and the overall height of equipment, achieve the maximization of deep cone thickener.Be connected with a transition conical tank body between cylindrical upper pool body with conical lower pool body, its outside diameter equals cylindrical upper pool body diameter, end diameter equals the outside diameter of conical lower pool body, reduce conical lower pool body with the deposition of solid of upper part, improve the dischargeable capacity of concentration basin, add hydraulic detention time.
Described cloth system is positioned at concentration basin center, and the diameter of distribution barrel upper shell is according to the design of ore pulp amount, and for ore pulp enters the passage of concentration basin between the large end of cone of distribution barrel lower shell and kuppe, cross sectional area increases progressively along current ascent direction.Kuppe and transition taper pool part form the turbulent region of settling ore pulp, and this region, under the disturbance of entering pond ore pulp, makes the solid particle be attached on pool wall float, and slippage downwards, enter conical lower cone.In addition; under the disturbance entering pond ore pulp, the solid particle in ore pulp presses particle diameter storied placement, coarse granule sedimentation; fine grained rises with current; when entering cross section, clear water zone, ascending current speed is less than the particle sinking speed that needs retain, and this partial particulate is separated with current; the particle accumulation of initially-separate is in bottom, clear water zone; along with the increase of ore pulp amount, a dynamic filtration layer be made up of fine grained is formed on top, turbulent region, and sedimentation and filtration are organically combined.Be clear water zone below downflow weir, more than turbulent region, cloth system bottom is Compression Settlement district, and body bottom, pond is mud district.
operation principle:in ore pulp gravity settlement process, solid particle has two speed, and one is self gravitational settling, and another is the rate of climb with current.When upwelling speed is greater than sinking speed, overall particle is in propradation, and finally arranges outward through downflow weir; When upwelling speed is less than sinking speed, particle is separated with water, realizes sedimentation.Ore pulp enters concentration basin through distributing device Dissipation, enters concentration basin.The follow-up ore pulp entered is to the ore pulp disturbance be introduced into, and solid particle is arranged naturally according to the size of density and particle diameter, density is large, particle diameter is large be positioned at below, density is little, particle is thin is positioned at upper strata.Now, solid particle sedimentation under gravity on the one hand, rise with ascending current on the other hand, the fluid passage formed due to distributing device and pond body progressively increases along cross section, ascending current direction, upwelling flow velocity progressively reduces, and the part that in solid particle, sinking speed is greater than upwelling speed is separated with upwelling.When the most fine grained needing to retain is when rising to cylindrical pool body position with current, upwelling speed is reduced to minimum, now fine grained no longer rises with current, gathers sedimentation in this position, forms one deck dynamic filtration layer, the more fine grained risen with current in ore pulp is filtered, when thickness of filter bed is increased to certain value, particle entirety under the extruding on upper strata of lower floor moves down, and enters densification decanting zone by turbulent region, meanwhile, the fine grained in ascending current forms new filter course.Through the water of filter course, continue to rise and arrange outward through downflow weir.Solid particle bottom sedimentation and lower pool body is arranged outward through mud discharging mouth.Be attached to the solids on transition pond body and lower pool body top pool wall, under the disturbance of turbulent region ore pulp, leave the downward slippage of pool wall.
As shown from the above technical solution, beneficial effect of the present invention: 1, dark cone concentration basin shell of column pond body designs separately with cone Duan Chiti; Decrease associating of cylindrical section pond body and conical section pond body, both met concentrated requirement, effectively reduce again the height of dark cone concentration basin, deep cone thickener can be realized and maximize; 2, adopt transition conical tank body to be connected between cylindrical upper pool body with conical lower pool body, decrease the deposition of solids at the bottom of shell of column pond, increase the dischargeable capacity of concentration basin, add hydraulic detention time; 3, deeply bore the combination of the pond body structure of concentration basin, cloth system structure and the pan feeding degree of depth, constitute the variable cross-section upwelling passage that is conducive to sedimentation, achieve the delaminating deposition of solid particle; 4, the disturbance of turbulent region ore pulp, washes away the solid be attached on transition-cone and lower cone pool wall, solid is fallen voluntarily, reduces the power consumption of scraping mud; 5, utilize pressure spoil disposal, reduce the energy ezpenditure of spoil disposal.
