Technical Field

The invention relates to a powder feeding mechanism, in particular to a reactive powder concrete powder feeding mechanism.

Background

At present, the stirring of current active powder concrete stirring and rabbling mechanism all adopts ordinary concrete mixing plant (or mixer), because added a large amount of steel fiber in the active powder concrete, when the active powder concrete powder state is piled up, form one because of the steel fiber effect and pile up the stable state, mobility is extremely poor, when leading to using ordinary concrete mixing plant stirring, the powder is difficult to follow and is treated in the hopper and fall into the agitator smoothly, causes the feed time long and not smooth, blocks up in even treating the hopper.

Similarly, due to the fact that the steel fibers are added, and the nanoscale powder exists in the powder, when the active powder concrete is stirred in a common concrete stirring station, the stirring time is as long as 12-20 minutes per disc, if the feeding is unsmooth, the situation that the active powder concrete is stirred for 30 minutes in one disc sometimes occurs, the stirring efficiency is greatly reduced, and continuous stirring work cannot be performed.

According to the related professional researches, the stirring quality of the reactive powder concrete can be ensured when the stirring linear speed of the reactive powder concrete is more than or equal to 6.3 m/s, and the optimal value of the stirring linear speed can not be achieved by a common concrete stirrer generally; because the water-cement ratio of the reactive powder concrete is very low, the reactive powder concrete is very sensitive to the error of water addition amount, and the accuracy of a water addition metering system of a common concrete mixer is difficult to meet the requirement; the problem of steel fiber agglomeration exists in the reactive powder concrete stirring process, and the problem of steel fiber agglomeration cannot be solved by a common concrete stirrer.
