Integrated slurry mixing equipment for difficult-to-float fine coal

The invention relates to the field of coal slurry pretreatment, in particular to integrated slurry mixing equipment for difficult-to-float fine coal. The equipment comprises a mixing box, wherein a drive shaft is vertically arranged in an inner cavity of the mixing box, and an electric field activation layer, an ultrasonic wave shocking layer and a forced stirring layer are sequentially arranged in the inner cavity of the mixing box from top to bottom in the length direction of the drive shaft. The equipment further comprises a pressurized gas dissolving box, an air inlet pipe used for introducing high-pressure air is arranged in a box body of the pressurized gas dissolving box, and a feeding partition board used for realizing opening and closing of an inlet end is arranged at an inlet end, used for being communicated with a discharge port of the mixing box, of the box body and is fastened through an extension spring and butted against the inlet end to close the inlet end; an outlet end of the box body is connected with a floatation machine, and a discharging partition board used for realizing opening and closing of the position is arranged at the outlet end, is tensioned through a compression spring and closes the outlet end. The equipment has a good conditioning function on floated coal mud, particularly meets the slurry mixing and conditioning demands of the difficult-to-float fine coal, has high working efficiency and rapidly and conveniently performs pretreatment.
