A large-diameter flotation column medium ore cyclone device and tailings cyclone discharge device

Abstract

The invention relates to a medium ore cyclone device and a tailings cyclone discharge device of a large-diameter flotation column, belonging to the technical field of flotation. A medium ore cyclone device and a tailings cyclone discharge device for a large-diameter flotation column according to the present invention consist of a column body, an upper cone, a middle cone, a lower cone, a medium ore feeding pipe, a bottom cone, The tailings discharge pipe and the tailings discharge barrel are composed; the upper cone is connected to the top of the middle cone, the top of the lower cone is connected to the bottom of the middle cone, the bottom of the lower cone is connected to the column, and the medium ore inlet pipe is connected to the column One end of the tailings discharge pipe is connected with the cylinder and the bottom cone, and the other end is connected with the tailings discharge barrel. The medium ore feeding pipe is connected with the column wall along a certain tangential angle and elevation angle. The tailings discharge pipe is connected to the bottom cone along a certain tangential angle and elevation angle. The beneficial effects of the invention are: the medium ore swirl flotation effect is good; the tailings are discharged in time, which solves the problem of tailings discharge pipe blockage and tailings "dead zone" problem at the bottom of the column.

Description

Technical field [0001] The invention relates to a medium ore cyclone device and a tailings cyclone discharge device of a large-diameter flotation column, belonging to the technical field of flotation. Background technique [0002] The medium ore cyclone device currently used in the flotation column is applied to the large diameter flotation column, which mainly has the following disadvantages: there are few opportunities for countercurrent collision of the medium ore slurry near the side wall of the column, and the medium ore cyclone flotation effect is poor. [0003] Currently used flotation column tailings discharge device technology is relatively mature, the main structure is to directly connect one or two discharge pipes on the side wall of the bottom of the column, relying on the pressure of the column slurry to self-flow to the tailings barrel for discharge. This structure is applied to a large-diameter flotation column. On the one hand, the discharge pipe at the botto...

[0002] The medium ore cyclone device currently used in the flotation column is applied to the large diameter flotation column, which mainly has the following disadvantages: there are few countercurrent collision opportunities for the medium ore slurry near the side wall of the column, and the medium ore cyclone flotation effect is poor

This structure is applied to a large-diameter flotation column. On the one hand, the discharge pipe at the bottom is easy to block; on the other hand, there is a "dead zone" in the tailings at the bottom of the column, and some tailings cannot be discharged in time, which directly affects the flotation effect.
