Description
The utility model belongs to the isotope screening installation in the industrial mechanized equipment.
Existing ore X ray separator is a character of utilizing different material different to the absorptivity of X ray, the strength information input computer of residual ray that will be after mineral aggregate absorbs carries out processing and identification, and then driving executing agency is separated ore with barren rock.The generation of this separator X ray needs higher voltage and corresponding cooling device and screening arrangement.So the equipment complexity, the working service trouble.
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art part, proposes a kind of simple in structure, the efficiency of separation is high, accuracy good, the life-span is long dry type ore separator.
The purpose of this utility model is to realize on the basis of X ray separator: its structure (see figure 1), comprise by what vibratory sieve 1, ribbon conveyer 2 and frame 3 were formed and give material conveying device, the ray detecting apparatus of forming by radiographic source 4, sodium iodide probe 5 and signal processing instrument 6, by the pneumatic separating device that electromagnetic gas valve 8 and air accumulator 9 are formed, radiographic source 4 is by isotopic number
137Cs and
241The compound γ source that Am forms, probe 5 aligns up and down with corresponding radiographic source 4, be positioned at the center of transfer passage, the lead-out wire of probe 5 is guided the input port of signal processing instrument 6 into, by signal processing instrument 6 shaped pulse signal input computer system 7 countings, computing and identification, the output control signal of computer system 7 is guided the control end of electromagnetic gas valve 8 into.
By transfer passage and corresponding radiographic source, sodium iodide probe, the separation unit that electromagnetic gas valve is formed can be one or more.
Vibratory sieve 1 is served adhesive tape with the mineral aggregate of certain particle size, and ribbon conveyer 3 is lined up mineral aggregate and is transported to compound γ source 4 and the detection mouth between 5 of popping one's head in different passages.Mineral aggregate is dished out from the top of front roll 14 after ray detection, and the residual ray that passes adhesive tape and mineral aggregate is received by probe 5 and amplifies, and computer 7 is counted by being sent to after 6 shapings of signal processing instrument again, computing and identification.When finding to be barren rock through the mineral aggregate that detects mouthful, send the time-delay control impuls, drive electromagnetic gas valve 8, with the barren rock former parabolic path that blows off, make itself and ore separation.
Advantage of the present utility model is:
1. automaticity height, sorting is accurate, steady quality, ratio of sorting and cleaning can reach more than 85%.
2. sorting particle size range is 25~200mm, and the single channel efficiency of separation can reach 2~10 tons/hour, so efficiency of separation height, applicability is good.
3. be applicable to the sorting of multiple massive ore, as gold, tungsten, coal and various rare metal.
4. equipment is single-minded, and is multiple functional, small investment, instant effect.
Fig. 1 is a structure diagram of the present utility model.
Fig. 2 is the side view of a kind of embodiment of the present utility model.
Fig. 3 is the vertical view of Fig. 2 embodiment.
Fig. 4 is the structure chart in a kind of compound γ source.
Fig. 5 is the cross-section structure of a kind of special-shaped adhesive tape of the utility model.
In conjunction with the accompanying drawings the utility model is described in further detail.
Fig. 2, Figure 3 shows that one or six passage ray separator structures.Special-shaped adhesive tape with six arc grooves forms six mineral aggregate transfer passages on motorized pulleys 14 and driving drum 10.The tightness of adhesive tape can be regulated by the tensioning screw after the frame 19.Six gamma ray projector 4 staggered being installed on the frame sill 18.Six sodium iodide probes 5 place respectively in six shielding pigs 13, and are installed in together on the entablature 17 of frame.Each probe aligns up and down with corresponding radiographic source 4, lays respectively at the center of each passage.Six electromagnetic gas valves 8 are installed in the dead ahead of cylinder 14 side by side, and the center of each passage is aimed in outlet respectively.The air inlet of air valve 8 joins by appendix 16 and air accumulator 9.Each lead-out wire 12 of 5 of popping one's head in is guided the input port of steady peak dual channel analysis instrument 6 into, the output port that the control end 15 of each air valve connects to computer.
After system starts, self-excited oscillation sieve and the mineral aggregate that comes is lined up six teams automatically on the adhesive tape face, the detection mouth that constitutes by source and probe successively.Blanking bar ray signal and the ray signal after mineral aggregate is decayed are sent to the TTL pulse signal that steady peak dual channel analysis instrument further amplifies and be shaped to standard by probe acceptance and after amplifying, and send into computer counting, computing and identification then.When discovery is barren rock by the mineral aggregate that detects mouth, provide control signal, behind suitable time-delay, open air valve barren rock is discharged.
Figure 4 shows that a kind of radiogenic structure.The casting metallic lead 27 that covers usefulness all over the screen in the steel sheel 28, the overlapping placement isotope in vertical core 21 bottoms
241Am26 and
137Cs25, cross-drilled hole 20 matches with cock 24.The center line of the vertical core 22 in the cock 24 coincides at the center of shown position and housing vertical core 21.This moment, the ray vertically upward that sends of isotope was all by hole 22, and penetrated after 21 alignments of hole, passed behind adhesive tape and the mineral aggregate by the probe reception, and transmitted intensity in this case is the strongest.Cock 24 links to each other with handgrip 23, rotates the ejaculation amount that handgrip 23 can be controlled ray, and when hole 22 turned over certain angle and hole 21 and no longer is communicated with, radiographic source just was in closed condition.
Figure 5 shows that a kind of cross-section structure of special-shaped adhesive tape.Adhesive tape is formed by upholding layer 29, strength layer 30 and compression layer 31.Upholding layer 29 and compression layer 31 is two kinds of sizing materials of different nature, and strength layer 30 is made of the tree lace rope.When special-shaped adhesive tape adopted the diagram inner arc surface, manufacturing process was simple, and adhesive tape flexural deformation is little, long service life.
