This invention discloses a negative pressure pumping silo storage process for wet sand. Wet sand with a moisture content ≥13.5% (prepared or separated) is transported to a vertically erected silo for storage. Gravity drainage is achieved using a gravity field. The downward-flowing capillary water, under the influence of the vertical gravity field, rapidly descends to the lower part of the silo. A water-repellent ring is installed at the bottom of the silo, collecting all the downward-flowing capillary water and isolating the accumulated capillary water at the bottom of the silo outside the sand discharge port, separating excess water beyond the bound water of fine sand, ultrafine sand, and tailings. The collected capillary water is then channeled through an air-water mixing pipe to form a capillary water penetration zone. The air-water mixing pipe is connected to a jet negative pressure pumping device via a main pipe for negative pressure pumping, ultimately obtaining qualified sand with capillary water and a moisture content of less than 10%, similar to the naturally bound water content of fine sand, ultrafine sand, and tailings, completely eliminating leakage during transportation.
