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. For example, the Chinese patent with the notification number CN102998147 provides a field sampling device and sampling method for filling slurry, which can be used for industrial field sampling and research on the flow characteri...

For example, the Chinese patent with the notification number CN102998147 provides a field sampling device and sampling method for filling slurry, which can be used for industrial field sampling and research on the flow characteristics of the filling slurry in the stope; the Chinese patent with the notification number CN203720175U , provides a device for testing the rheological properties of fresh concrete, which can measure multiple sets of data to balance the rheological parameters of the reaction materials, and is suitable for testing the rheological properties of fresh concrete in the laboratory; Hu Hua in The article "Modeling and Simulation Prediction of Slurry Rheological Parameters" published in Volume 44, Issue 1 of the Journal of Xiamen University (Natural Science Edition) provides a method for numerically simulating the rheological parameters of slurry, which is used to guide engineering practice Slurry proportioning and preparation; however, in the prior art, on-site industrial tests are time-consuming and laborious, and the cost is high, making it difficult to carry out a large number of experiments; due to the lack of theory, the numerical simulation results are still quite different from the actual ones, and can only be carried out Qualitative analysis; and laboratory physics experiments are the first choice for related research because they can physically simulate the actual conditions on site and the experiment cost is low

[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.
