Technical Field

The invention relates to an automatic lime milk preparation device.

Background

Slaked lime is a cheap regulator, inhibitor and inorganic electrolyte in the ore dressing industry, can adjust the pH value of ore pulp, increase the hydrophilicity, enable hydroxide ions and heavy metal ions in the ore pulp to form insoluble hydroxide, and enable the proportion of a collecting agent in a molecular or ionic state in water to change, thereby changing and adjusting the floatability of various minerals. In the existing mineral separation industry, powdered quicklime is generally used as a raw material for adding lime milk into ore pulp to achieve a mineral separation effect, and the powdered quicklime reacts with water to generate hydrated lime, but a large amount of dust pollution is generated in the manual lime milk preparation and slaking process, and a large amount of hot gas is discharged, so that great threats are brought to the health and safe operation of operators, and in addition, if the hydrated lime is directly purchased, the price is high due to the reasons of production cost, transportation cost, investment income and the like.

Advantageous technical effects

The invention can achieve the following technical effects:

the invention has the following advantages:

first, the invention can recover the smoke dust generated in the quicklime slaking process in a limited way, and solves the environmental protection problem of the quicklime field slaking and slaking process.

Secondly, the invention has simple structure and low energy consumption for comprehensively preparing the lime milk, and saves the investment and energy consumption for preparing, grinding and selecting, secondary transportation and the like of the hydrated lime. The flue gas generated in the slaking process of the quicklime is sealed and purified on site, the pipeline is short, and the ash can not be accumulated in the pipeline.
