Description

Technical Field

[0001] The present invention relates to the technical field of pulp flotation, and in particular to a mixed mineralization device. Background Art

[0002] Current mixed pulp flotation equipment is mainly improved by increasing the rotation speed and optimizing the internal structure.

[0003] Problems existing in the mixed pulp flotation equipment in terms of increasing the rotation speed include high energy consumption required for high rotation speed, limited range of rotation speed increase.

[0034] Compared with the prior art, the beneficial effects of the present invention are reflected in the following aspects:

[0035] 1. The structure of the present invention is reasonably designed. During the process of the mixture of pulp and reagent flowing through the spiral Venturi tube, according to the Venturi effect, when the mixture of pulp and reagent passes through a pipe with a reduced diameter, the flow rate will increase, which can promote the full dispersion and interaction of the pulp and the reagent, improving the mineralization effect.

[0037] 3. The present invention combines multiple stirring methods, resulting in a better mixing effect. Among them, the jet stirring mechanism uses the jet stirring transfer pipe and the jet stirring outer discharge short pipe. The pulp is transported and ejected through the jet stirring transfer pump to form a jet stirring effect. This stirring method can form strong local turbulence in the pulp, further enhancing the mixing degree of the pulp and improving the flotation efficiency. At the same time, the jet stirring adjustment nozzle at the outer end of the jet stirring outer discharge short pipe can adjust the intensity and direction of the jet according to needs, making the stirring more flexible and effective.

[0038] 4. The discharge port height of the present invention is adjustable. The discharge port lifting and adjusting mechanism drives the lifting and adjusting sliding tube to lift by using an electric control telescopic rod, and can flexibly adjust the height of the discharge port of the upper discharge pipe according to the liquid level of the pulp and the flotation situation, ensuring the smoothness and accuracy of discharging.

[0068] Embodiment 5:

[0069] Based on Embodiment 4, as Figure 2 shown in the figure, a louver type flow guiding mechanism 16 is arranged on the side wall of the mixed mineralization barrel 10. A plurality of flow guiding shaft connection holes 160 that penetrate radially are provided on the side wall of the mixed mineralization barrel 10. The louver type flow guiding mechanism 16 includes a louver flow guiding support shaft 161 rotatably connected in the flow guiding shaft connection hole 160.

[0071] During the actual application of the present invention, the pulp to be flotation-treated is input into the mixing and mineralizing barrel 10 through the ore inlet pipe 111, and the medicament is added into the mixing and mineralizing barrel 10 through the medicament adding pipe 114 to be mixed with the pulp to be flotation-treated.

[0072] The medicament includes a pH adjuster, a flocculant, a collector, an inhibitor, and a foaming agent.

[0073] The mixing and mineralizing mechanism 20 is used to realize the circulating pulp conditioning in the mixing and mineralizing barrel 10. The mixing and mineralizing delivery pump 22 is a centrifugal pump in the prior art. The mixing and mineralizing delivery pump 22 conveys the mixture of the pulp and the medicament input into the mixing and mineralizing barrel 10 to the spiral Venturi tube 23 together. The mixture of the pulp and the medicament flows through the Venturi tube converging section 231, the Venturi tube spiral section 232, the Venturi tube extended throat section 233, and the Venturi tube diverging section 234 in sequence. According to the Venturi effect, when the mixture of the pulp and the medicament passes through the pipe with a reduced diameter, the phenomenon of increased flow velocity will occur, which can promote the full dispersion and interaction of the pulp and the medicament, so that the pulp and the medicament can be very fully mixed together.

[0074] At the same time, when the mixture of the pulp and the medicament flows through the spiral Venturi tube 23, interfacial micro-nano bubbles can also be generated on the surface of the hydrophobic minerals, expanding the hydrophobicity difference between the target minerals and the gangue minerals. At the same time, the hetero-aggregation of the gangue minerals and the target minerals can be destroyed, promoting the peeling of the fine-grained minerals on the surface of the target minerals and improving the selective recovery of the target minerals.

[0075] When the mixture of the pulp and the medicament flows through the spiral Venturi tube 23, interfacial micro-nano bubbles are generated to realize directional hydrophobic regulation and reduce the phenomenon of slime covering.

[0076] The mixture of the pulp and the medicament that are fully mixed together then returns to the inside of the mixing and mineralizing barrel 10 through the mixing and mineralizing ore inlet pipe 212, and so on in a cycle until all the pulp and the medicament are fully mixed together.

[0077] The rotary stirring mechanism 12 is used to stir the pulp in the mixing and mineralizing barrel 10, further promoting the mixing of the pulp and the reagent and improving the mineralization effect. The stirring drive motor 125 on the output shaft drives the stirring drive driven pulley 124 to rotate through the stirring drive belt 127. The stirring drive driven pulley 124 then drives the stirring shaft 122 and multiple stirring short rods 123 to rotate together. The pulp is stirred by the stirring action of the multiple stirring short rods 123, further promoting the mixing of the pulp and the reagent and improving the mineralization effect;

[0078] The jet stirring mechanism 13 is used to stir the pulp in the mixing and mineralizing barrel 10. And the jet stirring mechanism 13 has no mechanical blades of the traditional stirring mechanism, which can greatly avoid wear with the pulp and extend the service life of the equipment;

[0079] The jet stirring and conveying pump 134 pumps out the pulp in the mixing and mineralizing barrel 10 through the jet stirring initial connecting pipe 133. Then the jet stirring and conveying pump 134 conveys the pulp to the jet stirring conveying pipe 131. The pulp in the jet stirring conveying pipe 131 is then discharged from each jet stirring outer discharge short pipe 132 and mixed with the original pulp in the mixing and mineralizing barrel 10. Using the flow velocity difference of the two pulp streams, the pulp in the mixing and mineralizing barrel 10 is stirred;

[0080] By replacing the type of the jet stirring adjusting nozzle 135, the shape dynamics of the pulp discharged from the jet stirring outer discharge short pipe 132 can be adjusted, and thus various stirring effects can be achieved;

[0081] And through the jet inclination adjusting mechanism 14, the orientation of each jet stirring outer discharge short pipe 132 can be adjusted, and thus the stirring effect can be adjusted.

[0082] The inclination adjusting driving worm 144 on the output shaft of the inclination adjusting driving motor 143 can drive the inclination adjusting driven worm wheel 142 to rotate. The inclination adjusting driven worm wheel 142 then drives the jet stirring conveying pipe 131 and each jet stirring outer discharge short pipe 132 to rotate together to adjust the orientation of each jet stirring outer discharge short pipe 132;

[0083] During the stirring process of the pulp, the louver type flow guiding mechanism 16 is used to guide the flowing pulp to achieve a better mixing effect. The output shaft of the louver driving motor 165 drives the louver driving driven gear 164 to rotate through the louver driving driving gear 166. The louver driving driven gear 164 then drives the louver flow guiding support shaft 161 and the louver flow guiding blades 162 to deflect together, adjusting the inclination angle of the louver flow guiding blades 162, and thus realizing the flow guiding function in various states;

[0084] The final target minerals will be discharged from the upper discharge pipe 112. The ore discharge port lifting and adjusting mechanism 15 is used to adjust the precise distance between the inner end of the upper discharge pipe 112 and the surface of the mixed ore pulp, so as to achieve a better separation effect of the target minerals;

[0085] When the inner rod of the lifting and adjusting drive rod 155 extends, it can drive the lifting and adjusting sliding cylinder 154 to move down and up in the vertical direction. The lifting and adjusting sliding cylinder 154 then drives the lifting and adjusting sliding pipe 152 to move down and up together, so as to adjust the distance between the lower end of the lifting and adjusting sliding pipe 152 and the surface of the mixed ore pulp.
