Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Figure 1 is a schematic diagram of a pulp classification system according to one embodiment of the present invention.
Referring to fig. 1, an embodiment of the present invention provides a pulp classification system, which includes a cyclone 7, a microbubble generator 3 for generating microbubbles from gas, and a pulp conveyor 5 for mixing pulp and microbubbles;
the microbubble generating device 3 is provided with an air inlet and an air outlet, and the ore pulp conveying device 5 is provided with an air inlet, a pulp inlet and a pulp outlet;
the air outlet of the microbubble generator 3 is connected with the air inlet of the ore pulp conveying device 5, and the pulp outlet of the ore pulp conveying device 5 is connected with the pulp inlet 8 of the swirler 7.
When the ore pulp grading system works, ore pulp enters the ore pulp conveying device 5, gas enters the microbubble generating device 3 to generate a large amount of micro bubbles, the generated microbubbles enter the ore pulp conveying device 5 to be fused with the ore pulp to flow and mix together, fine particle minerals or coarse particle enriched intergrowths in the ore pulp are adsorbed on the surfaces of the microbubbles in the flowing process, the ore pulp fused with the microbubbles enters the swirler 7 to be graded to form overflow matters and sediment matters, the overflow matters are discharged from the overflow port 9 of the swirler 7, and the sediment matters are discharged from the sediment port 10 of the swirler 7. Because the fine particle minerals or the coarse particle enriched intergrowths in the ore pulp are adsorbed on the surfaces of the microbubbles in the process of flowing the ore pulp in the ore pulp conveying device 5, the microbubbles are fully mixed with the ore pulp; when the microbubbles are fully mixed with the ore pulp, the fine particle minerals or the coarse particle intergrowths (target minerals) are uniformly distributed in the ore pulp, so that the ore pulp in the cyclone 7 is uniformly distributed, the separation of the fine particle minerals or the coarse particle intergrowths (target minerals) in the ore pulp in the cyclone 7 is facilitated, after the ore pulp enters the cyclone 7, the fine particle minerals or the coarse particle intergrowths (target minerals) carried by the microbubbles and most of water are subjected to small centrifugal force, and do rotary motion in the central area of the cyclone 7, and the separation speed is increased by extra buoyancy provided by the microbubbles.
It is worth mentioning that the cyclone is usually connected with the mill to form a closed system, the sand sediment of the cyclone enters the mill for regrinding, and the overflow is qualified and enters the sorting system. In general, the target minerals are mostly minerals having a large specific gravity, and therefore, it often occurs that fine particles of the target minerals, which have been dissociated by monomers, enter a sediment, resulting in over-grinding. In the embodiment of the invention, the cyclone achieves the purpose that fine-particle target minerals and coarse-particle intergrowth-enriched body minerals float upwards and overflow, thereby avoiding the phenomenon of over-grinding of the target minerals.

The system needs to control the pulp amount entering the cyclone, so the pulp pressure generated by the mortar pump is usually fixed and is preset, and the optimal separation feeding pressure of the cyclone is preset, so the method only needs to adjust the feeding pressure. Specifically, the step S105 may specifically include the following steps:
