PULP CONDITIONING DEVICE Russian patent published in 2017 - IPC B03B1/00 B03D1/14 

FIELD: mining.

SUBSTANCE: pulp conditioning device includes a cylinder-conical separating chamber with a tangentially disposed pulp inlet and a discharge port for withdrawing the coarse pulp fraction located in the conical part of the separation chamber and the pulp separator, a mixing chamber disposed in the cylindrical portion of the pulp separator connected by a branch pipes to an overflow chamber, Located on the bottom of the pulp separator. The device is provided with a hollow cylinder, inside of which there is the rotative axis, consisting of the upper and lower axes connected by crosses. The lower rotative axis is fixed in the support bearing, installed on the bottom of the overflow chamber, which has the form of a truncated cone with an angle of inclination of 20-30°. In the upper part of the separation chamber cylinder, the blades which are rotatable due to the tangential flow of the pulp and assembled into the wheel are fixed on the spokes. On the outer side along the length of the cylinder, the pins are helically welded, and in the mixing and outflow chambers the screw blades are welded for mixing. The truncated cone of the outflow chamber is closed by a rotating protective casing fixed to the lower rotative axis. The branch pipe for feeding the reagent is installed with the possibility of tangential feed of the reagent in parallel with the flow of pulp feed in the lower zone of the blades assembled into the wheel.

EFFECT: increase in the contact time of the reagent with the pulp particles, uniform mixing of the pulp, decrease in energy consumption and reagent consumption.
