Describe the utility model below with reference to accompanying drawings in detail, the utility model is not limited to the following specific embodiment, and is any to improvement of the present utility model with change and all to fall into protection domain of the present utility model defined by the claims.
The specific embodiment
As shown in Figure 1, the utlity model has frame 15, flotation unit is placed in frame 15 tops, and gravity concentration apparatus is placed in the frame 15.Wherein, flotation unit is a flotation column, comprise cylinder 9, washing pipe 7 is established in cylinder 9 tops, and the upper outside of cylinder 9 is provided with concentrate thing floss hole 6, and the bottom is provided with tailing outlet port, establish ore pulp inlet 8 between the upper and lower, air diffuser 10 is established in the below of ore pulp inlet 8, and the tailing outlet port below is provided with funnel 5, and the bottom of funnel 5 is connected with the feeding mouth of gravity concentration apparatus 11; Gravity concentration apparatus is a circular cone type barrier film jig plant, comprise jigging chamber 12, the awl bucket 3 below jigging chamber, be arranged on the barrier film 4 between jigging chamber 12 and the awl bucket 3 and barrier film done the transmission device that pumps, sieve water supplement port down is set on the awl bucket 3, and transmission device comprises ac motor 16, cycloidal reducer 1 and is connected with cycloidal reducer 1 and by the toggle of its drive.
The flotation unit on top utilizes air diffuser 10, blowing agent, floating agent to carry out flotation operation, because increasing of top flotation solid geometry size, prolonged the required time of mineral floating process, thereby increase the probability of mineral and flotation froth, medicament reverse-impact, improved mineral recovery rate and concentrate thing concentration ratio; Garden bevel-type barrier film jig plant is adopted in the bottom, is used to reclaim bulky grain monomer mineral and since utilization up and down the alternation current make diagrid nature bed or artificial bed loose, help valuable mineral and penetrate bed and reclaim.
Refer again to accompanying drawing 1 below and describe the course of work of the present utility model.At first, ore pulp enters in the flotation column cylinder 9 by ore pulp inlet 8, the buoyancy that overcomes ore dressing water under the gravity effect carries out sedimentation, compressed air enters cylinder 9 by being positioned at the enter the mouth air diffuser 10 of 8 belows of ore pulp, the a large amount of foams that utilize air diffuser 10 to produce make concentrate thing come-up be discharged by concentrate thing floss hole 6 by downflow weir, and remaining big grain monomer mineral has penetrated foam, fall into mine tailing in the funnel 5 of cylinder 9 bottoms, and discharge cylinder 9 by tailing outlet port.
Then, the mine tailing of discharging flows into jigging chamber 12 certainly by jig plant feeding mouth 11, the motor 16 of transmission device starts, drive toggle by decelerator 1, diaphragm of rubber 4 between the awl bucket 3 below jigging chamber 12 and the jigging chamber is done to pump, make-up water is under the alternating force effect of reciprocating barrier film 4 under the sieve that is flowed into by backwater supply mouth 14, per minute is done even motion, make the bed in the jigging chamber 12 loose, mineral begin layering according to different specific weight, the decline of current makes heavier big grain monomer mineral preferentially sink to awl bucket 3 by bed, and discharge by bulky grain mineral floss hole 2, lighter discarded object can not pass bed, discharges through tailings discharging mouth 13 by downflow weir under the effect of ascending current.
For guarantee that flotation column is efficient, even running and assurance mineral recovery rate, require the nozzle of air diffuser 10 to have very high wearability, can adopt wear-resistant ceramic or pillar, to guarantee precision and service life; In addition, the automatic device for preventing leakage that prevents spray nozzle clogging and decompression also is set in the air diffuser 10.
