Description

Technical Field

[0001] The invention relates to the technical field of tungsten ore flotation, and in particular to a high-efficiency tungsten ore flotation device. Background Art

[0002] Tungsten is a rare metal and an important strategic metal. Tungsten and its alloys are one of the most important functional materials in modern industry, national defense and high-tech applications. They are widely used in aerospace, atomic energy, shipbuilding, automobile industry, electrical industry, electronics industry, chemical industry and many other fields.

[0003] Tungsten ore is brittle and tends to become muddy during the crushing and grinding process, that is, tungsten fine mud minerals with a particle size of less than 74μm are produced. The mineral particle size composition is complex, which makes the recovery rate of tungsten fine mud generally low. At present, the method of adding collectors to the ore solution is generally adopted, and then through strong stirring, the tungsten ore with tiny particles is agglomerated under the action of the collector to facilitate flotation. However, this method will increase the stirring process before flotation, which will reduce the flotation efficiency of tungsten ore. At the same time, stirring will make the mud and other mixed impurities in the ore solution highly dispersed. If the flotation process is directly entered after stirring, the purity of the concentrate obtained by flotation will also be affected. In addition, the tungsten ore in the soil will be accompanied by a large amount of mud during flotation, which will further reduce the recovery rate of tungsten ore flotation.

At the same time, the electric control ring track 13 is started and the rotating ring 14 is driven to rotate on the outer wall of the limiting sleeve 10 through the moving column. The rotation of the rotating ring 14 will drive multiple ring shift gears 16 to revolve through multiple positioning seats 15. The multiple ring shift gears 16 will mesh and move on the teeth of the fixed gear ring 12, thereby realizing the self-rotation of the ring shift gear 16. The self-rotation of the ring shift gear 16 will drive the flotation scraper 17 to rotate, so that the flotation scraper 17 can rotate while revolving in an annular manner on the flotation separation ring 2 and the inner separation ring 19, so as to facilitate the froth on the fan-shaped space containing ore liquid between the flotation separation ring 2 and the inner separation ring 19 to be scraped to the separation baffle 20 on one side, and the froth is continuously scraped into the fan-shaped space for collecting concentrate, so that the concentrate remains in the space between the collecting ring 4 and the flotation separation ring 2, which is convenient for the subsequent further collection of the concentrate.

[0040] The above advantages are: the ore to be floated can be separated into a plurality of fan-shaped spaces for flotation, and the flotation scraper 17 which rotates on itself and revolves on the orbit can be used to scrape the tungsten ore foam on the fan surface to the adjacent collecting fan-shaped space.

[0043] It should be noted that: during the flotation process, the flotation seat 3 will be controlled to rotate on the purification base 1, and the rotation direction is opposite to the rotation direction of the dragon spiral blade 8. The rotation of the flotation seat 3 will drive the fixedly connected components such as the flotation separation ring 2, the inner separation ring 19 and the limiting sleeve 10 to rotate together. After the ore liquid in the limiting sleeve 10 is transported to the bottom, it will flow into the fan-shaped space with the fan-shaped screen plate 21 between the flotation separation ring 2 and the inner separation ring 19 through a plurality of drainage square tubes 18. The rotation of the flotation seat 3 will generate a certain centrifugal force on the ore liquid in the fan-shaped space, so that the mud in the ore liquid is deposited downward under the action of centrifugal force, and the froth of the agglomerated tungsten ore is concentrated above the ore liquid, so that the mud and the lower layer of liquid without tungsten ore froth slowly flow into the sewage discharge hole of the flotation seat 3 through the fan-shaped screen plate 21 for discharge;

In the process of continuous transportation and continuous mixing, the collector will be fully mixed with the tiny particle size tungsten ore in the ore liquid, and will not produce high-intensity stirring chaos, avoiding the situation where the high dispersion of mud and other impurities affects the subsequent flotation. In this way, the collector can be evenly mixed during the ore liquid transportation process, and the stirring process steps are reduced compared with the prior art, so that the flotation efficiency of the tungsten ore is higher.

[0046] During the flotation process, the flotation seat 3 is controlled to rotate on the purification base 1, and the rotation direction is opposite to the rotation direction of the dragon spiral blade 8. The rotation of the flotation seat 3 will drive the fixedly connected parts such as the flotation separation ring 2, the inner separation ring 19 and the limit sleeve 10 to rotate together. After the ore liquid in the limit sleeve 10 is transported to the bottom, it will flow into the fan-shaped space with the fan-shaped screening plate 21 between the flotation separation ring 2 and the inner separation ring 19 through a plurality of drainage square pipes 18. The rotation of the flotation seat 3 will The ore liquid in the fan-shaped space generates a certain centrifugal force, so that the mud in the ore liquid is deposited downward under the action of the centrifugal force, and the froth of the agglomerated tungsten ore is concentrated above the ore liquid, so that the mud and the lower layer of liquid without tungsten ore froth slowly flow into the drainage hole of the flotation seat 3 through the fan-shaped screening plate 21 for discharge. In this way, the centrifugal force generated by the rotation of the flotation seat 3 can be used to centrifugally separate the mud and froth in the ore liquid, and most of the mud in the ore liquid can be screened out to prevent the mud from affecting the recovery rate of subsequent flotation.

[0047] The rotation of the limiting sleeve 10 will drive the fixed gear ring 12 and the electric control ring track 13 to rotate together. At the same time, the electric control ring track 13 is started and the rotating ring 14 is driven to rotate on the outer wall of the limiting sleeve 10 through the moving column. The rotation of the rotating ring 14 will drive multiple ring shift gears 16 to revolve through multiple positioning seats 15. The multiple ring shift gears 16 will mesh and move on the teeth of the fixed gear ring 12, thereby realizing the self-rotation of the ring shift gear 16. The self-rotation of the ring shift gear 16 will drive the flotation scraper 17 to rotate, so that the flotation scraper 17 can rotate while revolving in an annular manner on the flotation separation ring 2 and the inner separation ring 19, so as to facilitate the flotation separation ring 2 and the inner separation ring 19.
