Problems solved by technology

The main disadvantages of these two methods are: intermittent sampling and measurement of the aqueous phase batching solution; slow detection speed; large error; difficult to operate, not suitable for the continuous and automatic technical transformation of the aqueous ammonium nitrate explosive production line
Because the concentration of the aqueous ammonium nitrate explosives water-phase batching solution is near the concentration of the high-temperature saturated solution, if the temperature drops slightly, the water-phase batching solution will precipitate ammonium nitrate crystals, so the method and device of this patent application cannot be used to measure the aqueous ammonium nitrate water The concentration of the phase batching solution

Abstract

The invention discloses an online real-time detecting device and method for density of hydrous nitrolite hydrofacies batching solution. It sets conductivity meter probe and temperature sensor in hydrofacies batching tank which connects with signal transmission transducer. The signal transmission transducer connects with computer. Set bleeder valve, steam valve and inlet valve on the hydrofacies batching tank separately. A spiral conveyer joints to the hydrofacies batching tank by a banking pipe. The steps are: calibrate standard curve and set data processing system for it in computer. Compare the tested temperature and conductivity with the corresponding standard curve to get density of tested solution. The invention can achieve solution density quickly and accurately, which realizes real-time detecting device and method for density of hydrous nitrolite hydrofacies batching solution. It uses computer to control materials transporting equipment, adjusts liquor density and controls flux of bleeder valve, steam valve and insulated steam.

Description

a technical field [0001] The invention relates to a detection technology for the concentration of the aqueous ammonium nitrate explosive water phase batching solution, in particular to an online real-time detection device and method for the aqueous ammonium nitrate explosive aqueous phase batching solution concentration. Two background technology [0002] Aqueous ammonium nitrate explosive has been vigorously developed in countries all over the world since it was invented by Cook in 1956. This is a kind of explosive with excellent performance and low price, which uses ammonium nitrate as oxidant and diesel oil, paraffin, etc. as reducing agent. The production process is : Dissolve 80% to 88% of ammonium nitrate in 8% to 10% of water, and add 4% to 10% of sodium nitrate as an auxiliary additive to solubilize and reduce the crystallization point of ammonium nitrate, and prepare an aqueous ammonium nitrate explosive The water phase solution; the diesel oil, paraffin and emulsif...
