Problems solved by technology

The mechanical agitation flotation machine has been used for the longest time. It has a history of nearly a hundred years from ore dressing to coal dressing. It can provide a turbulent environment for the flotation tank, but the disadvantages are high energy consumption and large maintenance
The non-mechanical stirring flotation machine, also known as the inflatable flotation machine, uses a pump to provide energy for the pulp, and absorbs enough air through the jet flow and collision of the pulp. The disadvantage is that it needs a matching pump and consumes a lot of energy.
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

[0042] For ease of understanding, combined here Figure 1-7 , the specific embodiments of the present invention are further described as follows:

[0043] The specific components of the present invention are divided into several major modules, including: flotation cell 60, flow diversion assembly, high-pressure injection assembly and lower stirring assembly, which are described one by one below:

[0044] 1. Flotation cell

[0045] As a conventional flotation device, the flotation cell 60 can be equipped with auxiliary flotation operation structures such as bubble scraping mechanism, so as to realize its inherent flotation function.

[0046] 2. Shunt components

[0047] shunt components to Figure 1-2 and Figure 7 When the structure shown is a specific embodiment, it is mainly subdivided into a sextant and a jet nozzle 13 connected to the end of the branch pipe 12 of the sextant.

[0048] As the main part of the diversion assembly, the sextant is set up to divide the flot...

Abstract

The invention relates to the field of pulp-mixing and flotation treatment of coal slime, in particular to flotation equipment with pulp self-drive and self-suction functions. The flotation equipment comprises a flotation tank, a flow distribution assembly for achieving a jet flow mixing function, a high-pressure jet assembly for achieving a turbulent flow mixing function and a lower stirring assembly for achieving a stirring and mixing function. The flotation equipment integrates pulp mixing and flotation and has the beneficial effects of being low in energy consumption, low in maintenance capacity, good in self-suction and sorting effects and capable of reducing the equipment input in the early stage of a coal preparation plant while the efficient flotation requirement of pulp is achieved efficiently and controllably and thus effectively lowering the actual production cost of the coal preparation plant.

Description

technical field [0001] The invention relates to the field of coal slurry flotation treatment, in particular to a flotation device with the functions of self-driving and self-absorbing of ore pulp. Background technique [0002] The flotation method 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 ore flotation, especially- The only effective sorting method for 0.1mm coal slime. 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 inc...
