When the fluid flows from the flotation machine impeller into the stator, a large dynamic pressure value appears at each piece of the stator, the velocity of the fluid is reduced by the resistance of the stator blade, the kinetic energy rotating ring is the pressure energy, and the fluid once leaves the impeller-stator area of ​​the flotation machine. Entering the flotation cell, the dynamic pressure suddenly drops and the flow rate drops dramatically.
In the stator vane flow channel, the total pressure is less than the total pressure in the stator external floatation cell, and the surface has eddy currents between the stator vanes.
The experimental research on the velocity of the fluid in the cross-section of the flow field at different locations inside the flotation cell shows that the structure of the double-layer impeller is reasonable. The pulp discharged from the upper and lower impellers of the flotation machine produces a vigorous stirring cycle in the lower part, while the upper impeller can cause the slurry in the upper part of the tank, ie in the separation zone, to move downwards, increasing the chance of flotation of the ore. The fluid within the stator inner circle of the impeller area is rotating; the liquid flow is reflected by the stator vanes, and between the outer edge of the stator and the inner circle of the distribution plate of the pseudo-bottom steady flow plate, the rotation flow is generated opposite to the impeller area, and the stator is A large number of eddy currents are generated between the blades, the flow field is distributed uniformly, there is no dead zone, the utilization rate of the flotation cell is high, and the structure of the flotation cell is reasonable.
The stirring zone of the XJM-S8 flotation machine is generally below Z-0.7m, and above 0.7m above the relatively stable flotation separation zone, the turbulent flow intensity is weak and evenly distributed. By analyzing the relationship between the turbulent characteristic parameters and the impeller's peripheral speed, it is found that when the impeller speed is changed, the distribution laws of turbulent kinetic energy, turbulence intensity, and turbulence dissipation rate remain unchanged.
After a long period of research and innovation by Henan Yuhui mine technical experts, our company's flotation machine equipment has become more mature. After the new flotation equipment is put into production, it is well received by the majority of merchants and welcomes merchants for consultation.
