Embodiment 1

[0027] A high-efficiency bubble generating device, including a mineralized bubble discharge pipe 1, a sieve plate 3, a cylinder body 4, an ore pulp feeding pipe 7, a high-pressure air inlet pipe 8, and a medium particle 9; On the side wall and communicated with the cylinder 4, the pulp enters the cylinder through the pulp supply pipe 7 along the tangential direction of the cylinder 4; the high-pressure air inlet pipe 8 is located on the opposite side of the pulp supply pipe 7, and is fixed on the side wall of the cylinder 4 and connected with the cylinder 4, the air enters the cylinder through the high-pressure air inlet pipe 8 along the tangential direction of the cylinder 4, and the swirling direction of the air is opposite to the swirling direction of the ore pulp; the top of the cylinder 4 is provided with a mineralized bubble discharge pipe 1. The cylinder body 4 and the mineralized bubble discharge pipe 1 are sealed and connected through the flange cover 2. The lower end ...

Embodiment 2

[0030] The structure of this embodiment is the same as that of Embodiment 1, the difference is that the diameter of the mineralized bubble discharge pipe 1 is 2 / 3 of the cylinder diameter, and the length of the mineralized bubble discharge pipe 1 extending into the cylinder body 4 is 1 / 2 of the cylinder height 2 / 5.

[0031] The cylinder body 4 is supported by a bracket 5, and the cylinder body 4 and the bracket 5 are flexibly connected, and the cylinder body 4 can be inclined at a certain angle along the bracket 5.

Embodiment 3

[0033] The structure of this implementation is the same as that of Example 1, the difference is that the mineralized bubble discharge pipe 1 and the flange cover are integrated and cannot be disassembled, and it is located at the center of the flange cover 2; the mineralized bubble discharge pipe 1 and the sieve plate 3 The connection is detachable.

[0034] During flotation, the ore pulp and flotation agent are mixed and sent to the flotation machine, where they are stirred and inflated, so that the target minerals to be floated are attached to the air bubbles to form mineralized air bubbles, which float to the surface of the ore pulp to form mineralized foam. Floor. Among them, pulp aeration and bubble mineralization are the two main processes of flotation, and they are also the main factors to evaluate the working efficiency of flotation machines; The degree of dispersion and the uniformity of distribution in the tank; the possibility of mineralization of air bubbles, mine...

Abstract

The invention relates to a high-efficiency bubble generating device and belongs to the technical field of mineral separation and environmental science. The high-efficiency bubble generating device comprises a mineral laden bubble discharging pipe, a screen plate, a cylinder, an ore pulp supply pipe, a high-pressure intake pipe and medium particles; the ore pulp supply pipe is arranged on the sidewall of the cylinder and communicates with the cylinder; ore pulp enters the cylinder through the ore pulp supply pipe in the tangential direction of the cylinder; the high-pressure intake pipe is located on the opposite side of the ore pulp supply pipe, is fixed to the side wall of the cylinder and communicates with the cylinder, air enters the cylinder through the high-pressure intake pipe in the tangential direction of the cylinder, and the swirling direction of the air is opposite to that of the ore pulp; the top of the cylinder is provided with the mineral laden bubble discharging pipe, and the cylinder and the mineral laden bubble discharging pipe are in sealed connection through a blind flange; the lower end of the mineral laden bubble discharging pipe is provided with the screen plate; and the cylinder is internally filled with the medium particles. The high-efficiency bubble generating device is suitable for recovering low-concentration micro-fine particle grade valuable minerals.

Description

technical field [0001] The invention relates to a high-efficiency bubble generating device, which belongs to the field of mineral separation and environmental science and technology. Background technique [0002] Pulp aeration and bubble mineralization are the two main processes of flotation, and they are also the main factors to evaluate the working efficiency of flotation machines. At present, mineral flotation equipment is mainly divided into stirring type and aeration type flotation machines. [0003] In the prior art, the mechanical agitation flotation machine has problems such as small air filling, high power consumption, and large wear, which leads to the failure of mineral particles to fully collide with the air, causing some valuable minerals to be lost in the flotation tail. mine. The inflatable flotation machine in the prior art is typically represented by a flotation column, which is characterized by a simple structure and is easy to manufacture, but due to the ...
