Abstract

A reactive powder concrete intelligent stirring system mainly solves the technical problems that an existing stirring machine is low in reactive powder concrete stirring efficiency, instable in stirring quality and large in water addition amount error and causes steel fiber caking. According to the technical scheme, the reactive powder concrete intelligent stirring system is characterized in thatthe reactive powder concrete intelligent stirring system comprises a stirring mechanism (1), a stirring round barrel (2), a feeding mechanism (3), a spraying water addition device (7), a water addition metering system (6), a discharging system (8), a stirring intelligent control system (9) and a dustproof system (5); the stirring mechanism (1) is installed in the stirring round barrel (2); the feeding mechanism (3) is arranged on one side of the stirring round barrel (2); the spraying water addition device (7) and the water addition metering system (6) are arranged on the other side of the stirring round barrel (2); and the discharging system (8) is arranged below the stirring round barrel (2). The reactive powder concrete intelligent stirring system is mainly applied to reactive powder concrete stirring and production.

Description

technical field [0001] The invention relates to an active powder concrete mixing and mixing mechanism, in particular to an active powder concrete intelligent mixing system. Background technique [0002] At present, the existing active powder concrete mixing and mixing mechanisms are all mixed by ordinary concrete mixing stations (or mixers). Since a large number of steel fibers are added to the active powder concrete, when the powder state of the active powder concrete is piled up, it will be formed due to the action of the steel fibers. A stable accumulation state with extremely poor fluidity, which makes it difficult for the powder to fall smoothly from the waiting hopper into the mixing bucket when mixing with an ordinary concrete mixing plant, resulting in a long and unsmooth feeding time, and even blocking in the waiting hopper middle. [0003] It is also because of the addition of steel fibers, plus the nano-scale powder in the powder, that when the active powder conc...
