Problems solved by technology

At the same time, because the non-mechanical agitation flotation machine needs to ensure sufficient ore flow and suction volume, the flow field in the flotation tank is often excessively turbulent, which will cause the mineralized particles to fall off during the flotation process, thereby affecting the flotation process. selection effect

Embodiment Construction

[0039] For ease of understanding, combined here Figure 1-5 , the specific embodiments of the present invention are further described as follows:

[0040] The specific components of the present invention are divided into several major modules, including: a flotation cell a, a piston part 60, a power assembly, a stirring assembly and a foaming agent vaporization assembly. in:

[0041] Flotation cell a and piston part 60 are integrated in such as figure 1 Inside the U-shaped tube 40 shown. The shape of the U-shaped tube 40 is in the shape of a tank with an opening facing upwards, and a vertical partition is arranged in the middle of the tank, thereby forming a U-shaped lumen structure of the U-shaped tube 40 . For the U-shaped tube 40, such as figure 1 As shown, a horizontal liftable bed b is arranged at the left pipe section 41 , and a horizontal liftable piston part 60 is arranged at the right pipe section 42 . Both the piston part 60 and the bed b form a sealing fit with...

Abstract

The invention relates to the technical field of mineral flotation, specifically to a piston-type flotation machine. The flotation machine comprises a flotation cell. A concentrate output tube and a tailing output tube are arranged at the wall of the flotation cell. A bubble input tube is arranged in the cavity of the flotation cell. There are two action states such as lift and return stroke when the bed is driven by a piston group. When the bed is lifted to the highest point of the stroke, an inlet of the concentrate output tube and an air outlet of the bubble input tube are both located abovethe bed, and an inlet of the tailing output tube is located below the bed. When the bed falls to the lowest point of the stroke, the inlet of the concentrate output tube, the air outlet of the bubbleinput tube and the inlet of the tailing output tube are all located above the bed. A first one-way valve is arranged inside the concentrate output tube, a second one-way valve is arranged inside thetailing output tube, and a third one-way valve is disposed inside the bubble input tube. The collision rate between mineral particles and bubbles can be effectively increased, and finally the flotation efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of mineral flotation, in particular to a piston type flotation machine. Background technique [0002] Flotation is the most important interface separation method, and it has been widely used in the fields of separation flotation of polymetallic ores, comprehensive utilization of complex ores, iron ore flotation, and non-metallic ores. The theoretical basis of various flotation processes is roughly the same, that is, due to the hydrophobic characteristics of the surface of the ore particles or the hydrophobic (air-friendly or oil) characteristics obtained after the action of the flotation agent, the ore particles will be in liquid-gas or water-oil. Agglomeration occurs at the interface. At present, the most widely used method is the froth flotation method, which includes the following processes: 1) After the ore is crushed and ground, various minerals are dissociated into monomer particles, and the particle ...
