Long arc gradually-contracting feeding pipe cyclone

Abstract

The invention relates to a long arc gradually-contacting feeding pipe cyclone. The long arc gradually-contacting feeding pipe cyclone is provided with a cyclone body; an overflow pipe is arranged at the center of the top of the cyclone body; a feeding pipe is arranged on the upper portion of the cyclone body; a cone and an underflow pipe are arranged on the lower portion of the cyclone body; the feeding pipe is composed of a straight pipe section and an arc pipe section; the arc pipe section comprises an inner arc section and an outer arc section; the arc length of the inner arc section is oneeighth to third eighths of the circumferential length of the cyclone body; the outer arc section is an arc determined by a point A, a point B and a point C; and the inner arc section and the outer arc section form a long arc horn-shaped reducing pipe jointly. The long arc gradually-contacting feeding pipe cyclone is novel in structural design, is remarkable in effect, and has the functions of well reducing energy consumption and prolonging the service life.

Description

Technical field [0001] The invention relates to the technical field of separation and classification equipment, in particular to a long circular arc gradually retracting feed pipe cyclone. Background technique [0002] At present, the cyclone used for heterogeneous phase separation and solid-phase particle classification is mainly composed of the cyclone body, the overflow pipe installed on the top of the cyclone body, the feed pipe located on the upper part of the cyclone body and It is composed of a cone and an underflow tube installed at the lower end of the cyclone body. The feeding tube and the body are generally connected in a tangential direction. The feeding tube mainly includes a tangential feeding tube, an involute feeding tube, and a spiral. Linear feeding tube, arc feeding tube and other forms; the common problem of these feeding tube forms is that the length of the feeding tube is short, and the slope of the feeding neck is very large (or there is no necking), causin...

Problems solved by technology

[0002] At present, the cyclone used for heterogeneous phase separation and solid phase particle classification is mainly composed of a cyclone body, an overflow pipe installed on the top of the cyclone body, a feed pipe located on the upper part of the cyclone body and The cone installed at the lower end of the hydrocyclone body and the underflow pipe are composed of the feed pipe and the body generally in a tangential way, and the feed pipes mainly include tangential feed pipes, involute feed pipes, and spiral feed pipes. Linear feed pipe, arc feed pipe and other forms; the common problems of these feed pipe forms are that the length of the feed pipe is short, and the slope of the feed neck is very large (or there is no neck), which causes the feed Great resistance, great energy consumption
