Description

technical field [0001] The invention belongs to the technical field of research on the law of flow and deposition of filling slurry, and in particular relates to a uniform filling system and method for filling slurry for testing the law of flow and deposition of filling slurry. Background technique [0002] It is very meaningful to carry out the research on the flow deposition law of the filling slurry, but because the flow deposition of the complex multiphase flow of the filling slurry is very complicated, it is difficult to study, and the relevant research is relatively lacking. At present, there are mainly three research methods for the research of filling technology: field industrial test, laboratory physical experiment and numerical simulation. On-site industrial experiments are time-consuming and costly, and it is difficult to carry out a large number of experiments; due to the lack of theory, the numerical simulation results are quite different from the actual results...

AI Technical Summary

Problems solved by technology

On-site industrial experiments are time-consuming and costly, and it is difficult to carry out a large number of experiments; due to the lack of theory, the numerical simulation results are quite different from the actual results, and only qualitative analysis can be performed; and laboratory physical experiments can physically simulate on-site actual conditions. conditions, and the experimental cost is low, so it is the first choice for related research

[0003] When performing slurry filling in the laboratory filling slurry flow deposition law model test, ensuring that the slurry filling is uniform is the premise of accurate and reliable test results, but due to the difficulty in controlling the speed of slurry delivery and the instability of manual operation This makes it difficult to evenly fill the slurry in the model test, which affects the accuracy of the test results and cannot provide reliable test data for the study of the flow and deposition law of the filling slurry.
