A swing-stirring flotation device with self-adjusting slurry function

Abstract

The invention relates to the field of coal slurry mixing and flotation treatment, and specifically relates to swinging-stirring flotation equipment with a self-slurry-mixing function. The swinging-stirring flotation equipment disclosed by the invention at least comprises a flotation cell, wherein a micro-bubble generation bed is arranged in the flotation cell; the micro-bubble generation bed comprises micro-bubble tubes; and a connection arm is arranged at each of the two ends of each micro-bubble tube to fix the co-end part of the micro-bubble tube. The equipment further comprises a gas pipeline, wherein the gas pipeline is communicated with the tube cavity of each micro-bubble tube through a prearranged gas channel in the corresponding connection arm; and micro-bubble generation holes used for ejecting a gas are densely distributed in the tube wall of each micro-bubble tube. The equipment further comprises power arms, wherein the two power arms are provided, and symmetrically arranged at the two sides of the micro-bubble generation bed; and a stirring baffle extends from the bottommost end of each micro-bubble tube, and the surface of each stirring baffle is vertical to the swinging direction of the micro-bubble generation bed. The equipment disclosed by the invention has the advantages of being great in micro-bubble flotation effect, easier in bubble mineralization, free from flotation 'dead areas' in the flotation cell, and more stable in foam layer; and the working efficiency and the flotation effect can both be effectively ensured.

Description

technical field [0001] The invention relates to the field of coal slurry flotation treatment, in particular to a swing-stirring flotation device with self-adjustment function. Background technique [0002] Flotation is the most important interface separation method, usually used for the separation of -0.5mm coal slime, and it is the only effective separation method for -0.1mm coal slime. There are many types of flotation machines, and the differences are mainly reflected in the inflation method and the structure of the inflation stirring device. At present, the most widely used classification method is to divide flotation machines into two categories: mechanical agitation type and non-mechanical agitation type according to the different aeration and agitation methods. The mechanical agitation flotation machine can refer to the Chinese patent announcement number "CN201711220U" named "mechanical agitation flotation machine", which uses the stirring of a mechanical agitator to...

Problems solved by technology

Since the non-mechanical stirring flotation machine has no stirring mechanism, the pump is used to provide energy for the pulp, and the jet flow and collision of the pulp are dispersed to absorb enough air. The disadvantage is that it needs a matching pump and consumes a lot of energy.

In addition, since the non-mechanical agitation flotation machine needs to ensure sufficient ore flow and suction capacity, the flow field in the flotation tank is often excessively turbulent, causing the mineralized particles to fall off during the flotation process, thereby affecting the flotation effect
