Single multi-stage type grading and sorting small-taper angle hydrocyclone

Abstract

The invention relates to a single multi-stage type grading and sorting small-taper angle hydrocyclone belonging to the technical field of mineral grading equipment. The single multi-stage type grading and sorting small-taper angle hydrocyclone disclosed by the invention can realize multi-stage grading and sorting of materials of different particle sizes and different densities, and can effectively prevent the problem that coarse particles are mixed in an overflow product due to short-circuit current of a hydrocyclone. The single multi-stage type grading and sorting small-taper angle hydrocyclone comprises a cylinder body, wherein a feeding hole is formed in one side of a column body, a bottom flowing hole is formed in the bottom end of an inverted cone body, the taper angle of the inverted cone body is smaller than 15 degrees, the diameter of the column body is greater than 25mm; the single multi-stage type grading and sorting small-taper angle hydrocyclone is characterized in that more than two stages of overflow pipe of different lengths and different diameters are arranged at the top of the column body, all the stages of overflow pipes are sequentially coaxially arranged in a sleeving manner according to a small-to-large order; a cylinder body top cover is arranged at the top end of the column body, the column body is fixedly connected with the cylinder body top cover; overflow pipe top covers are arranged at top ends of all the stages of overflow pipes, center through holes are formed in the overflow pipe top covers, all the stages of overflow pipes are respectively fixed in the center through holes of all stages of overflow pipe top covers, and all stages of overflow pipe top covers are connected with the cylinder body top cover by virtue of lead screws and nuts.

Description

technical field [0001] The invention belongs to the technical field of mineral grading equipment, and relates to a single-body multi-stage grading and sorting small cone angle hydrocyclone, in particular to a single-body multi-overflow pipe grading and sorting small cone-angle hydrocyclone . Background technique [0002] Chinese invention patent CN1974024A proposes a cascaded cyclone separation device, which is composed of two cyclones in series, and the guide inlet of the second-stage cyclone is directly connected with the bottom flow port of the first-stage cyclone. The underflow of the primary cyclone directly enters the secondary cyclone for secondary separation; the overflow of the secondary cyclone directly enters the cavity of the primary cyclone and is discharged through the overflow port of the primary cyclone or is connected to an outlet pipe lead out. The device involved in this invention patent is actually connected by two cyclones, the structural arrangement i...

Problems solved by technology

This utility model patent is similar to the double-pipe overflow pipe. Through the connection of two overflow pipes, three kinds of products with different thickness can be obtained after classification; however, it is suitable for the classification of materials with uniform particle size distribution, continuous and multi-stage separation. Efficiency still needs to be improved
