Description
Technical field
The utility model provides a kind of separator that mineral are carried out the continuous centrifugal sorting, and effectively the material of the different heavy mineral content of sorting is particularly useful for the high fine mineral depth cleaning of heavy mineral content.
Background technology
At present, the centrifugal classifier of mining processing industry application mainly is fluid bed centrifugal classifier and single wall formula centrifugal classifier.Though fluid bed centrifugal classifier such as efficiency of separation height such as Knelson, Falcon, effectively sorting heavy mineral content and the very low mineral of concentrate yield, but can not sorting heavy mineral content and high mineral of concentrate yield such as iron ore etc.; Single wall formula centrifugal classifier can be used for sorting heavy mineral content and the high mineral of concentrate yield, but because its sorting stream film thickness is very thin, the sorting space is very little, and it is generally very little to cause centrifuge to handle ability, the difficult requirement of satisfying mining processing industry production.
Summary of the invention
The purpose of this utility model provides a kind of spiral flow continuous centrifugal classifier, and this machine is sorting heavy mineral content and the high mineral of concentrate yield effectively, and also effective very low mineral of sorting heavy mineral content and concentrate yield have very strong adaptability.
The technical scheme that the utility model technical solution problem is adopted is: the tubbiness sedimentation locular wall in sealing inserts water inlet pipe, and the eddy flow post of tubbiness is installed on top, and the bottom connects and concentrates awl, concentrates under the awl and connects the concentrate pipe; Eddy flow post upper tangential inserts mineral-feeding pipe, and the bottom connects the sorting awl of coaxial bottom sealing, and the conical ring trench bottom of sorting conical inner surface is evenly equipped with tangential fluidisation hole, and the eddy flow capital is equipped with the debris tube that leads to sorting awl bottom.
The technical solution of the utility model also comprises:
Be evenly equipped with the normal direction stationary stream dividing plate vertical at expansion chamber with concentrated awl connecting position with the expansion chamber center line; The sorting conical inner surface is arranged the taper annular groove from top to down equably, and the quantity of annular groove can be selected different according to material properties, and the fluidisation hole feeds and tangential over against the ore pulp eddy flow, aperture from the conical ring bottom land.
The central lines of the expansion chamber of this centrifugal classifier, concentrated awl, eddy flow post, sorting awl and debris tube.
During work, clear water enters expansion chamber from water inlet pipe and forms certain water pressure.Adopt Pressure gauge to monitor in the mineral-feeding pipe pressure of water in the ore pulp feed and expansion chamber respectively, by cooperating these two pressure of regulation and control, centrifugal force field intensity that the control ore pulp rotates in the sorting space and water enter the sorting cone space from the fluidisation hole flow velocity, thus the comprehensive field of force that helps the mineral Selective Separation in the sorting space, set up.The heavy mineral that goes out from the sorting spatial sorting passes the fluidisation hole and enters expansion chamber, and is concentrated and discharge continuously from bottom concentrate pipe in concentrating awl by the stationary stream dividing plate; Artificial or control automatically (ore pulp pressure or concentration that the monitoring of utilization sensor concentrates in the awl realize) mode is regulated the concentrate valve switch, obtains required concentrate discharge concentration; Light mineral is subjected to that centrifugal force is little can not to enter the sorting space, crosses each taper annular groove from top to bottom with the ore pulp eddy flow and arrives sorting awl bottom, and upwards discharging continuously from central debris tube becomes mine tailing, and mass rate of emission adopts artificial or autocontrol valve is regulated.
Distinguishing feature of the present utility model is: (1) utilizes the pressure ore pulp in the taper sorting space inward turning living centrifugal force field of changing the line of production, and the fluidised form water pressure that enters with sorting space bottom tangent establishes the comprehensive field of force that is beneficial to the mineral Selective Separation jointly; (2) the peripheral concentrate concentrating space of sorting awl has concurrently and concentrates concentrate and the double action of isolation sorting mineral process (in the sorting space) with the concentrate discharge process, can realize the continuous blow-down of concentrate high concentration; (3) to rotate the sorting stream film thickness that forms in the sorting space big for ore pulp, have very strong storage ore deposit and buffering ability, the sorting space can be not at short notice by a large amount of heavy mineral filling compactings and lose the fluidization sorting function, can handle the very high mineral of heavy mineral content and concentrate yield.

Fig. 1 is an outfit of equipment fundamental diagram of the present utility model.
Fig. 2 is device A of the present utility model-A cutaway view.
Among the figure, 1. water inlet pipe, 2. mineral-feeding pipe, 3. debris tube, 4. eddy flow post, 5. sorting awl, 6. expansion chamber 7. concentrates awl, 8. concentrate pipe, 9. stationary stream dividing plate, 10. fluidisation hole.
The specific embodiment
As illustrated in fig. 1 and 2, clear water enters expansion chamber 6 from water inlet pipe 1 and forms certain water pressure, and ore pulp pumps in the eddy flow post 4 from mineral-feeding pipe 2 tangent lines, sets up centrifugal force field thereby its pressure can be converted into rotation function.Ore pulp turns in the following motion process in eddy flow post 4 inward turnings, owing to varied in size by centrifugal force, mine particle group carries out layering according to density contrast, and heavy mineral mainly is distributed in eddy flow post 4 outsides, light ore particle eddy flow post 4 inboards that mainly distribute, this delaminating process mainly carries out pre-sorting according to the cyclone principle.Ore pulp eddy flow after the pre-sorting enters in the taper annular groove sorting space that sorting bores 5 places and carries out sorting, wherein heavy mineral is subjected to centrifugal force big, overcoming the effect of fluidization water resistance discharges from the fluidisation hole, enter outer expansion chamber 6, arrive concentrated awl 7 by stationary stream dividing plate 9 and concentrate, connecting to discharge from concentrate pipe 8 then becomes concentrate; Light mineral is subjected to centrifugal force little, can't overcome the fluidization water resistance effect in the sorting space, with the bottom of ore pulp eddy flow arrival sorting awl 5, becomes mine tailing from central debris tube 3 continuous discharges.Gently, the selectivity assorting room of heavy mineral in the sorting space mainly carries out sorting according to fluid bed centrifugal classification principle.The pressure of centrifugal intensity that the ore pulp eddy flow forms in the taper sorting space and fluidization water inlet is respectively by regulating the valve control of mineral-feeding pipe 2 and water inlet pipe 1, to adapt to sorting mineral of different nature; Obtain the concentrate and tailings product of optimal solids concentration by valve artificial or automatic control mode adjusting concentrate pipe 8 and debris tube 3.
