Stirring type flotation machine for tailing redevelopment and utilization

Abstract

The invention belongs to the technical field of tailing redevelopment, in particular to a stirring type flotation machine for tailing redevelopment and utilization, and provides the following scheme: the stirring type flotation machine comprises a box body with an opening in the top, a stirring mechanism is arranged in the box body, and a foam scraping mechanism is arranged at the top of the box body; the middle positions of the top ends of the outer walls of the two sides of the box body are connected with a liquid injection pipe and a feeding pipe correspondingly; the bottom end of the outer wall of one side of the box body is connected with a liquid discharging pipe; the stirring mechanism is provided with a stirring rod rotationally connected between the inner walls of the two sides of the box body; one end of the stirring rod is in transmission connection with a driving mechanism; and a connecting cavity is formed in the end, away from the driving mechanism, of the stirring rod. Slurry rotating along with the stirring rod collides with the auxiliary pipe for buffering, so that rotating flowing of the whole slurry is reduced; and bubbles are reversely injected in cooperation with the auxiliary pipe, so that convection is further generated on the bubbles in the stirring rod and rotational flow, rotating movement of the slurry is eliminated, and the working efficiency and the using effect of the actual flotation machine are improved.

Description

technical field [0001] The invention relates to the technical field of tailings redevelopment, in particular to a stirring flotation machine for tailings redevelopment and utilization. Background technique [0002] The mining industry is an important raw material industry. Metal ore is the main raw material for the smelting industry, and non-metallic ore is an important chemical raw material and building material. During the process of ore mining and processing, a large amount of tailings are often produced and need to be redeveloped. Among them, the stirring flotation machine is an important equipment commonly used for tailings screening and re-opening. [0003] The flotation machine is suitable for the separation of non-ferrous and ferrous metals, and can also be used for the separation of non-metals such as coal fluorite and talc. Generally, the negative pressure is generated by the centrifugal action generated by the rotation of the impeller. On the one hand, sufficient ...

Problems solved by technology

[0003] The flotation machine is suitable for the separation of non-ferrous and ferrous metals, and can also be used for the separation of non-metals such as coal fluorite and talc. Generally, the negative pressure is generated by the centrifugal action generated by the rotation of the impeller. On the one hand, sufficient air is sucked to mix with the pulp, and on the other hand On the one hand, the pulp is stirred to mix with the medicine, and at the same time, the foam is refined, so that the minerals adhere to the foam, float to the surface of the pulp and then form a mineralized foam, and the foam and the minerals bonded to the foam are scraped out to achieve screening and separation, and then through subsequent processing It is under development, but in the actual use of the flotation machine of the prior art, due to the rapid rotation of the stirring mechanism, a large number of air bubbles and foams are caused to accumulate below the slurry, which is not convenient for rapid Rising discharge, affecting the actual use effect
