High-efficiency cyclone sorting preparer

Abstract

A separation preparation device of a high efficiency cyclone comprises a feeding chute barrel body, a upward flow branched pipe horizontal flow ring pipe and a valve, wherein the feeding chute barrel body is in a taper structure, a lighting device is arranged at the top of the feeding chute barrel body, an upward flow injection pipe and a raw coal diffusing device are arranged on the upper portion of the feeding chute barrel body, the horizontal flow ring pipe are arranged on the lower portion of the feeding chute barrel body, and a macromolecule antifriction liner is arranged on the inner wall of the feeding chute barrel body. The horizontal flow ring pipe and the upward flow injection pipe can effectively fully moisten the selected raw coal, moisten evenly the raw coal before being selected, shorten the dissociation process of the raw coal and suspension liquid, reduce the loss of energy, and specially suit for raw coal which is low in moisture and large in proportion of fine particles. The taper-shaped feeding chute can increase handling capacity of heavy medium cyclone, simultaneously, removes the feeding block phenomenon of the cyclone, removes clean coal parting phenomenon, and improves separation accuracy and working efficiency.

Description

Technical field [0001] The invention relates to a device for uniformly wetting raw coal before the separation of a pressureless heavy medium cyclone by applying a heavy medium suspension in the technical field of separation equipment, in particular to a high-efficiency cyclone separation preparer for mineral processing . Background technique [0002] In recent years, my country's heavy-medium coal preparation technology has developed rapidly. One of its important characteristics is the wide application of the coal preparation process centered on the pressureless heavy-medium cyclone. It has the advantages of small size, large processing capacity, high separation efficiency, and its own No power and other characteristics, especially for difficult to select and extremely difficult to select coal, has a significant separation effect. [0003] However, in the actual production process, due to the complex coal quality, it is often encountered that the feed chute is blocked or the clean ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the problem that when the raw coal in the prior art is not wetted or wetted before entering the cyclone, the mixing process of the raw coal and the suspension is too long, and the fusion and dissociation of the coal mass and the suspension takes a lot of time. For the problem that the effective separation time is shortened, resulting in a decrease in separation accuracy, a method consisting of a horizontal flow annular pipe, an upward flow jet pipe and a conical feeding chute is provided, which can effectively fully wet the raw coal for separation, and has high separation efficiency.
