A self-gravity fluidized bed piping system for powder curing agent transportation and its application method

Abstract

The invention provides a pipeline system of a gravity fluidized bed for transportation of a powder curing agent and a using method thereof. The pipeline system of the gravity fluidized bed is composedof a fluidized bed pipeline, a feeding hopper and air circulating compressor, wherein the fluidized bed pipeline is internally divided into three independent channels: an air inlet channel, a mediumtransportation channel and a gas recovery channel. The pipeline system of the gravity fluidized bed is used for cured construction of soil masses in geotechnical engineering and primarily solves the problem that the feeding channel is easily blocked in the injecting and mixing processes of the powder curing agent. By means of the principle of the fluidized bed, a proper amount of air is blown intothe powder, so that the powder has the characteristic of liquid flowing. The powder is transported forward obliquely under the action of gravity, so that the workload of manual feeding in the mechanical mixing process is reduced, the mixing uniformity and controllability are improved, the powder curing can be precisely injected according to a design demand, and the mechanical degree and the production efficiency are improved.

Description

technical field [0001] The invention relates to a self-gravity fluidized bed pipeline system for transporting a powder curing agent and its use method. The fluidized bed pipeline system is used for soil solidification construction in geotechnical engineering, and mainly solves the problem of powder curing agent filling In the process of mixing, the feeding channel is easy to be blocked. Using the principle of fluidized bed, an appropriate amount of air is blown into the powder, so that the powder shows the characteristics of liquid flow, and it is transported obliquely forward under the action of its own weight. In the process of mechanized mixing Reduce the workload of manual feeding, improve the uniformity and controllability of mixing, and accurately add powder curing agent according to the design requirements, improve the degree of mechanization and production efficiency. The utility model belongs to the technical field of rock and soil reinforcement engineering, bad soil ...

AI Technical Summary

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

Utilizing the principle of fluidized bed, a proper amount of air is blown into the powder, so that the powder exhibits the characteristics of liquid flow, and is transported obliquely forward under the action of its own weight, which solves the bottleneck problem of mechanical solidification and mixing, and improves the construction efficiency and construction efficiency. quality
