Description
Technical field
The invention belongs to the sludge screening installation, relates generally to a kind of separation of coarse slime device.
Background technology
Jigging machine, the equipment that heavily is situated between and often selects for use when current divider, flotation device, spiral, shaking table etc. all are present sorting coarse slimes, wherein the effective sorting scope of jigging machine is the coarse slime particle greater than 0.5 millimeter, can not effectively carry out sorting to fine coal slurry less than 0.5 millimeter, bad adaptability, the scope of application is narrow; The current divider that heavily is situated between more carefully need increase feed pressure during coal slime in the sorting granularity, draws thus power consumption to increase, and equipment attrition is serious; Flotation device has separating effect well for sorting less than the coal slime below 0.5 millimeter, but to sorting greater than 0.5 millimeter slime separation weak effect, and need add medicament during separation operation, increased sorting charge; Spiral fuselage height is big, and floor space is big, and inconvenience is installed, and needs sand pump to carry for the chats of ore deposit and circulation, and pulp density and amount are bigger to the product selecting quality influence; The operation factors of shaking table is many, and is wayward, and the coal slime disintegrate-quality is difficult for guaranteeing.
Summary of the invention
The purpose of the invention is exactly problem and the defective that exists at above-mentioned prior art, design provides a kind of crude coal slime separating water medium fluidized bed apparatus, reach improve sharpness of separation, guarantee separating effect, reduce occupation area of equipment, the purpose of energy saving, reduction sorting cost.
The basic design of the invention is, at water medium fluidized bed separator upper inner configuration feeding pipe, feed box is set above feeding pipe, and material pipeline two ends are connected in respectively on feed box bottom and the feeding pipe upper end; The overflow launder integral body that is provided with the concentrate outlet is consolidating of sealing with water medium fluidized bed separator upper outside wall and fits on the water medium fluidized bed separator upper part, and the last transverse plane of overflow launder is higher than transverse plane on the water medium fluidized bed separator; Sieve shape dividing plate is packed in water medium fluidized bed separator inner chamber bottom, and affixed with the underflow opening upper end; Set into the mouth of a river on water medium fluidized bed separator bottom side, water inlet is positioned at sieve shape dividing plate below; Water pump is arranged on water medium fluidized bed separator outside, and the water lines two ends are connected on water pump and the water inlet; Stirrer configuration so far constitutes crude coal slime separating water medium fluidized bed apparatus in feed box.
The invention is separating medium by utilizing ascending current speed with the autogenous medium of the different generations of coarse slime pan feeding decrease speed, make the different coal slime of density separate with spoil, realize the principle and the method for sorting, guarantee and improved separation of coarse slime effect and precision, and sorting does not partly have running gear in the device, and package unit has that floor space is little, energy saving, the separation operation fault is few, operation reliable, the characteristics of stable working, stable, long service life.This device also can adapt to the separation operation of other sludge except that coal slime.

The specific embodiment
Below in conjunction with accompanying drawing the invention embodiment is described in detail.Crude coal slime separating water medium fluidized bed apparatus comprises water medium fluidized bed separator 9, at water medium fluidized bed separator 9 upper inner configuration feeding pipe 4, feed box 2 is set above feeding pipe 4, and material pipeline 15 two ends are connected in respectively on feed box 2 bottoms and feeding pipe 4 upper ends; Overflow launder 5 integral body that are provided with concentrate outlet 8 are consolidating of sealing with water medium fluidized bed separator 9 upper outside walls and fit on water medium fluidized bed separator 9 upper parts, and the last transverse plane of overflow launder 5 is higher than transverse plane on the water medium fluidized bed separator 9; Sieve shape dividing plate 12 is packed in water medium fluidized bed separator 9 inner chamber bottoms, and affixed with underflow opening 11 upper ends; Set into the mouth of a river 10 on water medium fluidized bed separator 9 bottom side, water inlet 10 is positioned at sieve shape dividing plate 12 belows; Water pump 6 is arranged on water medium fluidized bed separator 9 outsides, and water lines 14 two ends are connected on water pump 6 and the water inlet 10; Agitator 1 is configured in the feed box 2; Water medium fluidized bed separator 9 inside, be positioned at sieve shape dividing plate 12 above density feeler lever 13 is set.Equipped material flowmeter 3 on material pipeline 15.Equipped water ga(u)ge 7 on water lines 14.Density feeler lever 13 also can be substituted by the density measurement system of other classes such as optical fiber, finishes control density process.
The separation operation process and the principle of crude coal slime separating water medium fluidized bed apparatus are as follows: the ore pulp in the feed box 2 stirs through material flowmeter 3 through agitator 1 and evenly feeds feeding pipe 4 along tangent line, and enter the logistics that is decline in the water medium fluidized bed separator 9 from top to bottom, recirculated water by water pump 6 through water ga(u)ge 7, water lines 14, water inlet 10, sieve shape dividing plate 12 enters in the water medium fluidized bed separator 9 from bottom to up, under 12 effects of sieve shape dividing plate, the current that rise form jet when passing through sieve shape dividing plate 12, make material in body, reach dispersion effect, because ascending current is different with the pan feeding decrease speed, make material middle part in water medium fluidized bed separator 9 form a stable fluidized bed for separation layer, again because of the density difference of pan feeding particle, make particle sinking speed create a difference, thereby provide foundation for sorting; The active force that the pan feeding particle is subjected in water medium fluidized bed separator 9 comprises thrust, resistance, gravity and buoyancy, and the thrust that is subjected to is the amount relevant with water velocity with resistance.When the flow velocity that acts on particle was identical with particle speed, the density of particle equaled separator 9 fluidized bed for separation layer density just, and particle forms suspension in separator, become the autogenous medium of sorting; When pan feeding particle during less than fluidized bed for separation layer density, the flow velocity that promptly acts on particle is during greater than the speed of particle, and particle is carried in the overflow launder 5 to discharge from concentrate outlet 8 under flow action becomes concentrate; When pan feeding grain density during greater than fluidized bed for separation layer density, the flow velocity that promptly acts on particle is during less than the speed of particle, and particle continues to move downward, and passes the fluidized bed for separation layer, becomes mine tailing and discharges from underflow opening 11, thereby finish whole separation operation process.Density feeler lever 13 plays the effect that detects separating density, control sharpness of separation.Agitator 13 makes the material in the feed box 2 even.
