The invention discloses a material dissolving
system, which belongs to the technical field of
chemical engineering devices, and comprises: a reaction container provided with a reaction cavity, a
solid feed port, a liquid feed port, a
discharge port and a return port; the charging
assembly is connected to the
solid charging opening, and the charging
assembly can close the
solid charging opening; the feeding
pipe fitting is connected to the liquid feeding opening, and the feeding
pipe fitting is communicated with a liquid material source; the circulating liquid discharging
assembly comprises a circulating
backflow pipe and a pressurizing conveying device, the two ends of the circulating
backflow pipe are communicated with the discharging opening and the material returning opening respectively, and the pressurizing conveying device is arranged on the circulating
backflow pipe and used for reinjecting liquid discharged from the discharging opening to the material returning opening; the local arrangement path is arranged in the reaction container, and the
cooling pipe fitting is used for cooling the interior of the reaction container. According to the invention, materials in the chemical dissolving process can be isolated from the outside, a closed reaction and transfer environment is formed, volatile
combustible gas is effectively prevented from leaking, and explosion is avoided.
