Specific embodiment
For the ease of understanding the utility model, below in conjunction with Figure of description and preferred embodiment to practical new herein
Type, which is done, more comprehensively, meticulously to be described, but the protection scope of the utility model is not limited to following specific embodiments.
Embodiment:
As shown in Figure 1, the air self-suction formula Ultrafine Grinding flotation device of the present embodiment, including cylinder 1 and feed pipe 2, feed pipe 2
One section is located at outside cylinder 1, and another section is located in cylinder 1, and the pipeline section of feed pipe 2 being located at outside cylinder 1 is equipped with 21 He of feed inlet
Air inlet 22, feed inlet 21 are connected with one for being passed through the Pulp pump 23 of mineral aggregate and floating agent into cylinder 1.When Pulp pump 23
When being passed through material and floating agent into feed pipe 2 from feed inlet 21, due to the flowing of material, one can be generated at air inlet 22
Fixed negative pressure makes floating agent generate bubble to automatically introduce gas；The pipeline section of feed pipe 2 being located in cylinder 1 is parallel
In cylinder 1 axis and be suspended at the top of cylinder 1, so that material is directly declined by gravity, accelerate charging rate, improve
Powder feeding efficiency, while intake velocity is also improved, accelerate the generation speed of bubble；Feed pipe 2 is from air inlet 22 to positioned at cylinder
It is equipped at the mutation that diameter becomes smaller between pipeline section in body 1, material flow has been further speeded up by the diameter mutation at this, i.e.,
Further improve the efficiency of flotation work.
In the present embodiment, feed pipe 2 is more, can be faster to being passed through material inside cylinder 1, and when a feed
When pipe 2 blocks, other feed pipes 2 can work as usual, will not influence flotation work；More feed pipes 2 are along the circumferential equal of cylinder 1
Even laying makes material being passed through in cylinder 1 more evenly.
In the present embodiment, equipped with the milling medium for being ground mineral aggregate, the discharge port of feed pipe 2 is located at for the bottom of cylinder 1
The top of milling medium effectively can avoid discharge port from being blocked by mineral aggregate.The middle part of cylinder 1 is equipped with the charging of a milling medium
Mouth 11, feed opening 11 is located at the top of milling medium, for supplementing the milling medium of consumption.The top of cylinder 1 is equipped with
One leads to external ore pulp efferent duct 12, for be discharged it is levigate after mineral laden bubble；Cylinder 1 is that top sectional area is cut greater than lower part
The ladder pillar buoy of area, the structure that this top extends out increase mineral aggregate and overflow area, improve production efficiency.Cylinder 1
Lower section is equipped with sand sinking port 13 at bottom surface, for the mineral aggregate that can not be ground to be discharged.
