Active washboard fluidized bed pipeline for powder material transportation and method of use thereof

Abstract

The invention provides a driving washboard type fluidized bed pipe for powder material transportation and an application method thereof. The fluidized bed pipe consists of a pipe outer wall, a wave washboard separation layer, a gas pipe and a reverse flushing nozzle. The fluidized bed pipe system is used for curing construction of soil in geotechnical engineering, mainly solves the problem of easyblockage of a charging channel in the injecting and mixing process of a powder curing agent, uses a fluidized bed principle for blowing a proper amount of air into powder through the reverse flushingnozzle to enable the powder to present the liquid flowing characteristic, in particular, uses eddy currents formed by reverse flushing air currents on the arc wave washboard separation layer for forwards transporting powder materials, and can transport split materials to the other end of the pipe when the pipe is horizontal or even upwards inclined by a small angle. The manual charging workload is reduced in the mechanical mixing process; the mixing uniformity and controllability are improved; the powder curing agent can be precisely injected according to design demands; and the mechanical degree and the production efficiency are improved.

Problems solved by technology

This fluidized bed pipeline system is used for soil solidification construction in geotechnical engineering, mainly to solve the problem that in mechanized mixing construction, the conveying pipeline is usually blocked, forming a powdery arch structure, making it impossible to add curing agent, and the feeding channel is easy to block question

Using the principle of fluidized bed, the right amount of air is blown into the powder, so that the powder shows the characteristics of liquid flow, and it is transported horizontally forward under the push of the air flow, which solves the bottleneck problem of mechanical solidification and mixing, and improves the construction efficiency and construction quality.
