Automatic preparation and supply system and method for emulsion

The invention discloses an automatic preparation and supply system and method for emulsion. The automatic preparation and supply system for emulsion comprises a ground concentrated emulsion preparation system, horizontal buffering water tanks and a mining area emulsion pump station, the ground concentrated emulsion preparation system is connected with the horizontal buffering water tanks, the horizontal buffering water tanks are connected with the mining area emulsion pump station, emulsified oil is delivered to a pipeline through emulsified oil pumps and an emulsified oil flowmeter, purified water is delivered to the pipeline through purified water pumps and a purified water flowmeter, emulsion prepared in the pipeline is delivered to a ground matching box, the emulsion in the ground matching box is delivered to the horizontal buffering water tanks through delivery valves, emulsion flowmeters and reducing valves, and the emulsion entering the horizontal buffering water tanks is delivered to next-level horizontal buffering water tanks through delivery valves and reducing valves in sequence. The system and method can effectively solve the problems that manual emulsion preparation precision is low, efficiency is low, the water quality of mine water is poor, a soap graining reaction is likely to occur and consequently hydraulic systems cannot work normally.
