The invention relates to a pressurization gas
dissolution type
coal slime mixing device, and belongs to the technical field of
coal slime flotation equipment. The pressurization gas
dissolution type
coal slime mixing device is used for coal slime flotation pulp mixing treatment. According to the technical scheme, the pressurization gas
dissolution type coal slime mixing device comprises a pressurization bin, an ore pulp feeding jetting device, a stirring pulp mixing device and a
pressure reduction discharging device; the pressurization bin is of a cylindrical structure,
ellipsoid-shaped sealing heads are arranged at the two ends of the pressurization bin, the sealing head at the upper portion is connected with a
barrel of the pressurization bin through a detachable
flange, the sealing head at the lower portion and the
barrel of the pressurization bin are welded, and the ore pulp feeding jetting device, the stirring pulp mixing device and the
pressure reduction discharging device are all installed in the pressurization bin. According to the pressurization gas dissolution type coal slime mixing device, the characteristics of
aerosol feeding, intense stirring and the like are kept, the gas dissolution time is prolonged, the gas dissolution pressure is improved, the process of
microvesicle separation is highlighted, the coal slime
mixing effect is strengthened, and adaptability of flotation equipment for inlet flotation ore pulp is strengthened. The pressurization gas dissolution type coal slime mixing device has the beneficial effects that the unit treatment capacity of the flotation equipment can be improved, and agent consumption is reduced; and the pressurization gas dissolution type coal slime mixing device is very suitable for flotation of low-rank coal slime with poor surface hydrophobicity and slime with
large particle size.
