Description

An automatic control dosing device for coal preparation flotation

technical field

The utility model relates to the technical field of flotation coal preparation and dosing, in particular to an automatic control dosing device for coal preparation flotation.

Background technique

Flotation coal preparation refers to the separation of coal slime in the aerated coal slurry according to the wettability of the particle surface. Flotation is carried out on the interface where solid, liquid and gas are in contact with each other. These three are called three phases, namely solid phase, liquid phase and gas phase. Therefore, to discuss the flotation process, it is necessary to study the surface phenomena that occur on the three-phase interface. In flotation coal preparation, it is usually necessary to add medicine, so a dosing device is needed.

At present, flotation coal preparation is a common method for clean coal preparation in coal preparation plants. Usually, raw coal ore particles are added to water and then stirred to dilute them into coal slime, and then corresponding proportions of collectors and foaming agents are added to the inside for stirring. After a period of time, it is finally sent to the flotation machine for air-filled flotation. Usually, the dilution and stirring process and the mixing process of adding medicine need to be carried out separately, and in order to ensure the proportion of the medicine, a fixed amount of coal slime is added to the stirring device Then add the corresponding amount of medicine to the mixing device. After the mixing is completed, it is also necessary to transport the mixed coal slurry mixed with the medicine and then repeat the above dosing process to reduce the proportion error. This requires a large space and equipment to remove Dosing and stirring, so a coal preparation flotation dosing device is needed that can do the dosing during the transportation of coal slime, and at the same time collect the infiltrated liquid medicine for reuse.
