1. A solid-liquid phase reactor for preparing a powder product, comprising a vessel shell, a material-restricting partition net, a solid reactant charge opening, and a reaction solution make-up opening, wherein the material-restricting partition net is disposed in a cavity of the vessel shell and is connected to a vessel body of the vessel shell;
the material-restricting partition net is enclosed to form a semi-closed material-restricting zone with an upward-facing opening itself or together with an inner wall of the vessel body; a frame of the semi-closed material-restricting zone is rigid; the solid reactant charge opening is in communication with the upward facing opening of the semi-closed material-restricting zone, and the reaction solution make-up opening is in communication with an internal space of the semi-closed material-restricting zone;
further comprising an acid-alkali concentration detection apparatus which is fixed on the inner wall of the vessel body and runs into the cavity of the vessel shell to be in contact with the reaction solution or unfixedly floats on a liquid surface of the reaction solution or suspends in the reaction solution;
and further comprising an intelligent control system, which is in electrical connection with the acid-alkali concentration detection apparatus, a solid reactant charge opening switch and a reaction solution make-up opening switch.
