Abstract

The invention discloses a concentration and separation two-section cyclone. The innovation point is that the concentration and separation two-section cyclone is formed by combining a concentration cyclone and a water medium separation cyclone in series, and the concentration cyclone and the water medium separation cyclone are separately arranged; and the concentration cyclone is positioned at the lateral upper side of the water medium separation cyclone. Each of the concentration cyclone and the water medium separation cyclone comprises elements such as a feeding tube, a barrel body, a cone body, an overflow tube, a bottom-flow tube and a flange plate; and a bottom flow hole of the concentration cyclone is connected with the feeding tube of the water medium separation cyclone through a connecting tube. The concentration cyclone can improve concentration of fed materials of the water medium separation cyclone, and also discharges a portion of fine particles, so that the separation effect of the water medium separation cyclone is improved. The concentration and separation two-section cyclone disclosed by the invention can be used for simplifying a process system of a coal preparation plant, is convenient to manage, is small in floor space, and reduces mounting cost and production operation cost.

Description

technical field [0001] The invention relates to the technical field of coal preparation, in particular to a two-stage cyclone for thickening and separating coal slime. Background technique [0002] The aqueous medium separation cyclone is an important coarse coal slime separation equipment, which has the advantages of simple structure, small footprint, convenient maintenance, low production cost, large processing capacity, etc., and is widely used in the coal preparation process Sorting aspects with coarse slime. [0003] At present, in the process of separating coarse coal slime, the aqueous medium separation cyclone is limited to the actual production situation of the coal preparation plant, and the concentration of the slurry water fed to the aqueous medium separation cyclone sometimes appears extremely low. In this situation, it is not conducive to the formation of the separation density layer of the water medium separation cyclone, which reduces the separation accuracy...
