AI Technical Summary

Technical Problem

It is difficult for the existing filling pipe self-flow performance detection and testing device to achieve accurate detection of the filling material self-flow conveying performance parameters, especially in slurries containing coarse particles and low viscosity. It is difficult for conventional L-tube testing devices to form a full-tube flow state, resulting in small flow and pipe pressure measurement results, and the unevenness of the slurry affects the accuracy of the data results.

Method used

A filling pipe self-flow performance detection and testing device is designed including an agitator, a discharge mechanism, a material stabilizing plate, a vertical pipe, a horizontal pipe and a high-speed camera. By raising the slurry at the slurry outlet, the continuous and stable flow of the slurry is achieved using a stable material tray, and the particle running state of the slurry in the pipeline is recorded through a high-speed camera to ensure the formation of the full-tube flow state.

Benefits of technology

Accurate detection of the self-flow conveying performance parameters of the filler material is achieved, ensuring the stable flow of slurry in the pipeline, reducing labor intensity, improving the cleanliness of the site, and providing more accurate monitoring of the slurry pipe transportation situation.

Abstract

The utility model discloses a testing device for detecting the self-flowing performance of a filling material pipeline. The testing device comprises a filling material stirring barrel, a vertical pipe and a horizontal pipe, wherein the filling material stirring barrel is provided with a stirrer and a discharging mechanism. The upper end opening of the material stabilizing disc is located below the discharging mechanism, and the lower end of the material stabilizing disc is provided with a material stabilizing disc discharging pipe. A discharging pipe of the material stabilizing disc is connected with a vertical pipe, the lower end of the vertical pipe is connected with a longitudinally-arranged transparent pipe, and the lower end of the longitudinally-arranged transparent pipe is connected with a horizontal pipe through an elbow. The horizontal pipe is connected with a section of transparent pipe in the horizontal direction, and the transparent pipe in the horizontal direction is connected with a discharging pipe. And a discharge valve is mounted on the vertical pipe. And a high-speed camera is mounted on the transparent tube. By lifting the slurry outlet, full-pipe conveying of the monitoring section in the slurry conveying process is achieved. By additionally arranging the material stabilizing disc with the low height-diameter ratio, the slurry can continuously and stably flow downwards along the pipeline. A high-speed camera is arranged on the pipeline to record the running state of slurry particles in the pipeline at different positions of the vertical section and the horizontal section, so that the slurry pipeline conveying condition can be mastered more accurately.
