Problems solved by technology

[0005] The present invention provides a tailings deposition test system, which is used to solve the problem in the background that the pulp stored in the storage tank is discharged into the deposition model tank through a pumping system. If the pulp in the storage tank is stored for too long The solid particles are easy to deposit in the storage tank, resulting in the change of slurry concentration during the ore drawing process, and the size of the model tank used by the current researchers for tailings deposition is small. If the ore flow rate and particle size are reduced, it is difficult to meet the similar conditions for erosion and siltation; if the similarity ratio is not considered, the test is carried out according to the flow rate and particle size of the prototype test, and the interference effect of the side wall is very large, resulting in unclear boundary conditions for the model test Any technical issue in

Abstract

The invention provides a tailing deposition test system which comprises a stirring system, a pumping and discharging system, a deposition model tank, a wake flow backflow circulating system and a monitoring system, and the stirring system, the pumping and discharging system and the deposition model tank are sequentially connected through test pipelines. The sedimentary model tank and the wake flow backflow circulation system are respectively connected with the stirring system through test pipelines, a stirrer is arranged in a material storage pool of the stirring system, a monitoring system is arranged on the sedimentary model tank, the stirrer is started during ore drawing, and the situation that particles in tailing pulp deposit in the material storage pool, so that the concentration of ore pulp changes in the ore drawing process is prevented; the technical problem that when ore pulp stored in a storage pool is discharged into a sedimentary model groove through a pumping system, if the storage time of the ore pulp in the storage pool is too long, solid particles in the ore pulp are prone to depositing in the storage pool, and the concentration of the ore pulp changes in the ore drawing process is solved.

Description

Technical field [0001] The present invention relates to the field of engineering experiments, and more particularly to a tail deposition test system. Background technique [0002] Drawing test is widely used in research in hydraulics, sediment dynamics and geological deposition structure, and has carried out sediment sludge ecosystems against mud movement law, wandering river evolution, alluvial fan growth law, and large water conservancy project. Experimental study on problems. Scholars have analyzed from different perspectives for the applicability of the groove test. Southard et al. (Southard, Boguchwal et al. 2010) believes that loose deposits are enrolled in water flow. Some scholars believe that the inherent principle can be studied in a phenomenon observed in a large-scale prototype test (Küpper 1991). In recent years, with the expansion of the scale test and the development of measurement techniques, high-precision, digitally real-time real-time monitoring system is used ...
