Description

A pulp pretreatment system that strengthens the dispersion of flotation agents

technical field

The utility model relates to a pulp adjusting equipment before mineral flotation, in particular to a pulp pretreatment system which strengthens the dispersion of flotation agents.

Background technique

In recent years, the lean and fine hybridization of newly mined ores in my country has become more and more serious, which makes the cost of mineral flotation continue to increase, which is reflected in the increase in chemical consumption in the process of mineral flotation. The effect of pulp pretreatment before mineral flotation directly affects the effect of flotation. The traditional pulp pretreatment equipment only cuts and disperses the reagents through impeller agitation, but for insoluble flotation reagents such as hydrocarbon oils or fatty acids, relying only on the agitation of the impeller can easily cause uneven dispersion of the reagents, and the agitation The surface tension of the cutting and dispersing agent is high, it is insoluble in water, and it is easy to merge again to form large droplets, which makes the chance of contact and collision with fine mineral particles smaller, which will inevitably reduce the efficacy of the drug and increase the consumption of the drug. It is difficult to achieve a good flotation effect.

Contents of the invention

The purpose of the utility model is to provide an ore pulp pretreatment system that strengthens the dispersion of flotation reagents. The system can fully disperse the flotation reagents through multiple functions and strengthen the subsequent flotation effect.

In order to solve the above-mentioned technical problems, the technical solution adopted by the utility model is: a slurry pretreatment system for strengthening the dispersion of flotation agents, including two parts: a mixing tank and a jet device. Among them, the side wall of the upper end of the mixing tank has a discharge port, and the lower end has a material inlet; the upper part of the mixing tank has a mounting bracket, and the mounting bracket is welded and fixed with the hollow sleeve; the upper part of the hollow sleeve is cylindrical, and the lower part is umbrella-shaped , the upper and lower parts are welded together, the upper part of the hollow sleeve has 2 symmetrical slurry suction ports, the lower part has 4 symmetrical slurry suction ports, the lower part of the hollow sleeve is welded with a stator; The big pulley is connected, the middle is equipped with a small impeller, and the bottom is installed with a large impeller; the big pulley is connected with the small pulley through a belt, and the small pulley is driven by a motor; the inner wall of the mixing tank is welded with 4 baffles. The jet device includes a jet device, a pump and a pipe. The upper part of the jet device has a dosing port, the pipe inlet communicates with the feeding port of the mixing barrel, and the pipe outlet communicates with the hollow sleeve along the tangential direction of the hollow sleeve.

The beneficial effects of the utility model are: for the flotation reagents, especially insoluble hydrocarbon oil or fatty acid and other reagents, after being added into the jet device, the reagents can be preliminarily dispersed in the pulp through the high-speed impact and cutting of the pulp flow, and the reagents can be added The slurry flow enters the hollow sleeve in a tangential form to form a swirling flow, which further divides the agent. At the same time, the agitation and cutting of the small impeller makes the agent disperse more evenly. Finally, the agitation of the large impeller and the circular suction of the slurry suction port can make the agent It is fully mixed with the ore pulp, and the dispersion of the medicine is high, so as to achieve the effect of improving the efficacy and reducing the consumption of medicine.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings, but the utility model is not limited.

With reference to accompanying drawing 1, the utility model comprises two parts of mixing bucket and jet fluid device. Wherein, the side wall of the upper end of the mixing tank body 6 has a discharge port 3, and the lower end has a material inlet 10; the upper part of the mixing tank has a mounting bracket 17, and the mounting bracket 17 is welded and fixed with the hollow sleeve 15; the upper part of the hollow sleeve 15 is Cylindrical, the lower part is umbrella-shaped, the upper and lower parts are welded together, the upper part of the hollow sleeve 15 has two symmetrical slurry suction ports 7, and the lower part has four symmetrical slurry suction ports 7, and the lower part of the hollow sleeve 15 is welded with a stator 9; The mixing barrel is provided with a rotating shaft 16 along the axis, the upper part of the rotating shaft 16 is connected with the large pulley 18, the small impeller 4 is installed in the middle, and the large impeller 8 is installed in the lower part; the large pulley 18 is connected with the small pulley 1 through a belt, and the small pulley 1 is driven by the motor 2 drive; the inner wall of the mixing barrel body 6 is welded with 4 baffles 5 .

The upper part of the jet 13 has a dosing port 14, the inlet of the pipeline 12 communicates with the feeding port 3 of the mixing tank, and the outlet of the pipeline 12 connects with the hollow sleeve 15 along the tangential direction. Tube 15 communicates.

Working process: when the pulp enters the mixing tank through the feed port 10, part of the pulp enters the jet 13 under the action of the pump 11, and the high-speed shear jet pulp generated by the jet 13 emulsifies the medicine added from the dosing port 14; emulsification After entering the hollow sleeve 15 together with the pulp along the tangential direction of the hollow sleeve 15, a swirling flow is formed to further disperse the medicine. At the same time, driven by the motor 2, the small impeller 4 on the rotating shaft 16 is equiaxial with the large impeller 8 Rotate at a speed of 500-700rpm, in which the small impeller 4 plays the role of cutting and dispersing the agent, and the big impeller 8 plays the role of stirring the pulp; during the process of stirring the pulp with the big impeller 8, the pulp is sucked in circularly through the pulp suction port 7, The pulp and the medicine are fully mixed, and finally the medicine and the pulp are evenly dispersed by the stator 9; at the same time, the baffle plate 5 acts as a turbulent flow, which is beneficial to the dispersion of the medicine and the mixing of the medicine and the pulp. The well-mixed pulp and chemicals are fed to the flotation equipment through the outlet 3 of the mixing tank for flotation.
