The specific embodiment
Below will combine Figure of description and specific embodiment that the present invention is explained further details.
Like Fig. 1, Fig. 2, Fig. 3 and shown in Figure 4, efficient hydraulic classifier of the present invention comprises grading room 3; Be divided into decanting zone 31 and enrichment region 32 in the grading room 3 from top to bottom; Be provided with sedimentation type sloping plate component 7 in the decanting zone 31, the side on grading room 3 tops is provided with to the ore deposit assembly, and the bottom of enrichment region 32 is provided with gape 5; The top of grading room 3 is provided with overfall 6, and the side of decanting zone 31 is provided with the more than one water device 4 of adding.Material slowly flows into side mine-feeding equipment 2 through baffle-box 1; The back gets into the mineral coarse grain rapid subsidence of grading room 3, middle grade, and water device 4 is added the rising effect of water under, classification of sedimentation once more on the swash plate of sedimentation type sloping plate component 7 adding; Particulate is gone out the effect that reaches classification from 6 overflows of opposite side overfall under the effect of ascending water; After the mineral of coarse grain are deposited to the enrichment region 32 of branch unit room, discharge through sand setting gape 5.
In the present embodiment, comprise baffle-box 1 and side mine-feeding equipment 2 for the ore deposit assembly, the port of export of side mine-feeding equipment 2 is communicated with grading room 3, and the entrance point of side mine-feeding equipment 2 is communicated with baffle-box 1.Side mine-feeding equipment 2 is provided with ore pulp dispersal device 21 with the place of connection of grading room 3.The feed port of side mine-feeding equipment 2 be on the grading room 3 feed place outer wall girth 1/5～1/10.Baffle-box 1 is reduced the speed to the ore deposit in mine-feeding equipment, reduces to produce turbulent phenomenon when getting into grading room 3; Side mine-feeding equipment 2 expands flow region on the Breadth Maximum of grader to, adds the ore pulp dispersal device 21 of interface, makes ore pulp be divided into a lot of threads, and ore pulp speed and any turbulent flow of following can minimize like this; Can give the ore deposit to the grader tangential, make fine in the ore pulp, go over, reduce carrying secretly in the overflow from the overflow of grader top cross.
In the present embodiment, being cylinder with 31 corresponding positions, decanting zone on the grading room 3, is conical hopper with enrichment region 32 corresponding positions on the grading room 3.
In the present embodiment, sedimentation type sloping plate component 7 comprises the swash plate more than two, and the arranged direction of swash plate and the angle of vertical direction are 48
0～53
0, swash plate is installed in the decanting zone 31 near overfall 6 directions.In grading room 3, be blank near half zone of feed port, make the sedimentation of coarse-grained material elder generation, increase sedimentation type sloping plate component 7 near second half zone of overfall 6, its uses shallow layer settling principle, has shortened the sedimentation time of particle greatly, helps the classification of particle.Ore pulp is brought medium and small material in the swash plate under the effect of swash plate bottom at ascending water, and fine continues to rise through the top overflow, and thicker material is deposited on the swash plate, is deposited to the bottom again.
In the present embodiment; Add water device 4 and be two and be positioned at the both sides of decanting zone 31; Add water device 4 and be provided with narrow meshed catch 41 (referring to Fig. 4) with grading room 3 joining places; To add water in adding grading room 3 processes, and become a lot of threads by a big thigh, water speed and any turbulent flow of following can minimize like this.Add water device 4 through being added with in grading room 3 both sides near enrichment region 32; The moisture of adding that feeds from the bottom scatters and slowly rises, and has reduced the impact of water and ore pulp, makes grading room 3 interior turbulent flows drop to minimum; Ore pulp is difficult to the water hole is stopped up simultaneously, has improved classification efficiency.
In the present embodiment; The gape 5 of enrichment region 32 bottoms is equipped with sand setting ore discharge device and densimeter 8, and densimeter 8 links to each other with automaton 9, and densimeter 8 links to each other with brake apparatus; Be preset with a fixing running ore thickness in the automaton 9; When densimeter recorded gape 5 change in concentration, brake apparatus was just adjusted the size of gape 5, and this moment, the concentration of gape 5 was got back to setting value.
Application example: certain mine is a vanadium titano-magnetite; The content of-0.038mm grade in raw ore reaches 63.76%, and the Metal Distribution rate of its iron is 39.33%, TiO2 Metal Distribution rate is merely 17.99%, therefore; This part can directly be thrown as mine tailing and remove; So both can eliminate of the influence of thin mud, and can reduce the processing ore deposit amount of follow-up separation operation again significantly, thereby can save equipment investment and production run cost the follow-up separation operational indicator.
Use novel hydropower classifying equipoment and common dense bucket and make an experiment, feed particle size is-2mm under equal feed ore concentration and running ore thickness, to obtain the result and see table 1.
Table 1
Can find out that from table 1 under identical process conditions, adopt the present invention to exclude rate than common dense bucket to this ore deposit and exceed 6.33%, it is approaching to obtain sand setting concentrate iron recovery, TiO
2The rate of recovery exceeds 3.45%.The efficiency of separation obviously improves.
Below only be preferred implementation of the present invention, protection scope of the present invention also not only is confined to the foregoing description, and all technical schemes that belongs under the thinking of the present invention all belong to protection scope of the present invention.Should be pointed out that for those skilled in the art some improvement and retouching not breaking away under the principle of the invention prerequisite should be regarded as protection scope of the present invention.
