The invention provides a
powder fracturing fluid continuous blending method. The method comprises conveying
powder into a material hopper, installing a spiral
powder relaxer in the material hopper sothat materials are easy to
discharge, installing a
weight loss compensation sensor at a
discharge port of the material hopper, accurately measuring the total amount of powder in the material hopper inreal time, feeding the powder into a spiral feeder through a
pipe, electrically connecting the spiral feeder and the
weight loss compensation sensor, feeding back to a
control system so that precisefeeding is realized, connecting a
discharge port of the spiral feeder to a side port of an ejector, respectively connecting an inlet and an outlet of the ejector to a first water inlet main
pipe and asecond water inlet main
pipe, sucking the powder into the ejector under a vacuum
suction force produced by a high-rate
water flow, mixing the powder and clear water, diluting the solution through thesecond water inlet main pipe until an appropriate concentration, conveying the solution into a blending
system, carrying out uniform stirring, carrying out
viscosity adjustment, and conveying the solution to the next process section. The method greatly improves the accuracy of powder weighing, improves the
automation degree and reduces a production cost.
