Power-function-shaped conical swirler

Abstract

The invention relates to the technical field of solid-liquid-gas three-phase separating and sorting equipment and in particular to a power-function-shaped conical swirler. The power-function-shaped conical swirler is composed of a feeding pipe, a cylindrical barrel, an overflow pipe, a conical pipe and a bottom flow pipe. The feeding pipe is connected with the outer wall of the cylindrical barrelin a tangent line or involute or spiral line or other line shape feeding mode, the overflow pipe is arranged in the middle of the upper end of the cylindrical barrel, the lower end of the overflow pipe stretches into the cylindrical barrel, and the conical pipe is arranged at the lower end of the cylindrical barrel. The power-function-shaped conical swirler is characterized in that the conical pipe is arranged to be a round pipe with the perpendicular section in a power function shape, the upper end of the round pipe in the power function shape is connected with the lower end of the cylindrical barrel, and a bottom flow opening is formed in the lower end of the round pipe in the power function shape and is connected with the bottom flow pipe. The power-function-shaped conical swirler has the advantages that the sorting space of the lower portion of the swirler cone is enlarged, a zero-speed enveloping surface section is optimized, the mismatching probability of coarse and fine particles of materials in the swirler is reduced, and the overflow particle size composition of the swirler is improved.

Description

technical field [0001] The invention relates to the technical field of solid-liquid-gas three-phase separation and sorting equipment, in particular to a power function that utilizes a tapered gradient curvature structure to suppress the mismatch of material coarse and fine particles inside a cyclone and increase overflow optional particle size content conical cyclone. Background technique [0002] As we all know, a cyclone is a separation device for separating heterogeneous phase mixtures, which can be used for solid-liquid separation, liquid-gas separation, solid-solid separation, liquid-liquid separation, and liquid-gas-solid separation. The cyclone is usually connected by a cylinder and a cone, including overflow pipes, underflow pipes, feed pipes and other main components. According to the use of the cyclone, the structure of the cyclone will also be different. For example, the cone part can be divided into standard cone angle (20 degrees), large cone angle (greater tha...

[0003] Since the traditional cyclone cone is a straight cone, the curvature is a fixed value, and the classification index of each particle size is "one size fits all" during operation. Whether it is by adjusting the outlet ratio, cone angle, pressure or feed concentration, the overall Under the premise that the fineness index remains unchanged, the probability of a single change in a certain particle size entering sand settling or overflow
