A separation preparation device of a high efficiency cyclone comprises a feeding chute barrel body, a upward flow branched pipe horizontal flow ring pipe and a valve, wherein the feeding chute barrel body is in a taper structure, a lighting device is arranged at the top of the feeding chute barrel body, an upward flow injection pipe and a raw coal diffusing device are arranged on the upper portion of the feeding chute barrel body, the horizontal flow ring pipe are arranged on the lower portion of the feeding chute barrel body, and a macromolecule antifriction liner is arranged on the inner wall of the feeding chute barrel body. The horizontal flow ring pipe and the upward flow injection pipe can effectively fully moisten the selected raw coal, moisten evenly the raw coal before being selected, shorten the dissociation process of the raw coal and suspension liquid, reduce the loss of energy, and specially suit for raw coal which is low in moisture and large in proportion of fine particles. The taper-shaped feeding chute can increase handling capacity of heavy medium cyclone, simultaneously, removes the feeding block phenomenon of the cyclone, removes clean coal parting phenomenon, and improves separation accuracy and working efficiency.
