Description

Technical Field

[0001] The utility model relates to the technical field of tungsten ore mining, in particular to a scheelite scavenging flotation machine. Background Art

[0002] Scheelite is an ore with a granular stone shape, white with yellow, having a greasy luster, orange, bipyramidal crystals, large crystals, and the tips being transparent dark orange. It coexists with calcite, muscovite, and black cassiterite. Among them, scheelite and calcite have fluorescence, and when heated or irradiated by ultraviolet light, they are slightly purple. It is the main raw material for tungsten smelting. Scheelite can be used to manufacture firearms, nozzles of rocket boosters, and cut metals. It is a metal with a wide range of uses. The main technology for the purification of scheelite concentrate is flotation, and the key technology of flotation lies in the flotation machine.

[0003] For example, the patent document with the publication number CN211190606U discloses a device for improving the grade of scheelite concentrate in tungsten ore mining. Through the air inlet pipe on the connecting cylinder and the air pump on the air inlet pipe, the air intake effect is improved. Moreover, through the air pump, air can be actively introduced to generate a large number of bubbles, thereby improving the flotation effect and efficiency. It is provided with a double impeller, which can improve the negative pressure formed by the impeller through the first impeller and the second impeller on the rotating rod, thereby improving the mixing effect. Through the cleaning brush bristles on the rotating rod, not only can the blockage in the connecting cylinder be avoided, but also the inner wall of the connecting cylinder can be cleaned.

[0004] During the use of the above patent, although the negative pressure formed by the impeller can be improved through the first impeller and the second impeller on the rotating rod, the first impeller and the second impeller are fixed and cannot greatly improve the mixing effect.

The other end of the feeding pipe 303 is welded with a feeding hopper 304. The top of the first rotating shaft 201 is connected with a stirring frame 305 through a coupling. The top end of the stirring frame 305 extends into the fixing box 302. Pulp is added to the feeding hopper 304, so that the pulp flows into the fixing box 302 through the feeding pipe 303. The aeration mechanism includes a bearing plate 401, which is welded on the top of the box body 1. A connecting pipe 402 is welded in the bearing plate 401.

By the operation of the motor 206, the first rotating shaft 201 is driven to rotate, so as to drive the second impeller 207 to rotate. At the same time, by the rotation of the first rotating shaft 201, the first gear 202 can be driven to rotate, so as to drive the two second gears 204 to rotate, and then drive the two second rotating shafts 203 to rotate, so as to drive the two first impellers 205 to rotate. By the rotation of the first impeller 205 and the second impeller 207, the solid particles and reagents in the pulp can be fully mixed, and at the same time, the bubbles can be promoted to be evenly distributed.

By the rotation of the first impeller 205 and the second impeller 207, the solid particles and agents in the pulp can be fully mixed, and at the same time, the uniform distribution of bubbles can be promoted. When injecting the pulp into the interior of the box body 1, by the operation of the air pump 404, the air filtered by the filter screen 502 can be sucked in through the air inlet pipe 405, and then discharged into the fixed box 302 through the connecting pipe 402 to increase the amount of bubbles in the pulp. At the same time, the rotation of the first rotating shaft 201 can drive the stirring frame 305 to rotate, so as to stir the pulp when the pulp is added to the fixed box 302, increase the gas content in the pulp, and thus further increase the amount of bubbles. The finally processed pulp is discharged through the discharge pipe 102. When it is necessary to clean the dust and sundries on the filter screen 502, pull the filter screen 502 through the handle 503, so as to pull the filter screen 502 out of the fixed box 501, and then clean it.
