ABSTRACT:
A pulsator for enriching, particularly, hard coal has mounted in a pulsating compartment a hoisting wheel and a bracket both mounted on a drive shaft, or a ratchet wheel mounted on a drive shaft which runs in bearings above the liquid level of a working trough. The pulsating compartment is of cylindrical shape and is connected to working trough along its longer side and separated from the working trough with a wall. The pulsating compartment consists of an outer wall to which is welded a bottom wall shaped as an arc and connected via a vertical wall to an oblique wall of the working trough. The bottom wall is provided at its lowest point with a grate encased with a pulp outlet stub pipe. The hoisting wheel consists of a side wall connected with an outer screen which is connected in turn to an outer ring along the periphery of the outer screen. Inside of the hoisting wheel a perforated crown is installed at an acute angle and connected from the top above the side wall of the pulsating compartment to a discharge chute in the form of a trough provided with a bottom plate. Paddle buckets are mounted on the perforated crown. A displacer is secured inside of the hoisting wheel on a hub keyed on the drive shaft consisting of two plungers, of the shape of a closed hourglass in the vertical section and made up from two side plates connected with an outer circumferential plate.
