Abstract

The invention discloses a test device and a test method for a wear test of a filling slurry conveying pipeline, and the test device comprises a stirring tank, a conveying assembly connected with the output end of the stirring tank, and a test pipeline assembly connected with the output end of the conveying assembly. The output end of the test pipeline assembly is connected with the input end of the stirring tank; and the test pipeline assembly comprises a plurality of horizontal pipelines, elbows, inclined pipelines and vertical pipelines which are connected with one another. By means of the mode, the abrasion law of filling slurry with different proportions in a horizontal pipeline, an inclined pipeline, a vertical pipeline, an elbow and the like can be studied, the flow and the flow speed of the filling slurry can be controlled so as to simulate various test environments, and the test effect is better.

Description

technical field [0001] The invention relates to the technical field of mine solid waste filling, in particular to a test device and a test method for wear testing of filling slurry conveying pipelines. Background technique [0002] In the mine filling system, the filling pipe plays an important role as the exclusive channel for the filling slurry. The flow of filling slurry in the pipeline will inevitably cause corrosion and friction to the pipeline, causing the filling pipeline to be worn or damaged. At present, many domestic mines using the filling method have encountered the technical problem of serious wear of the filling pipeline. Once the filling pipeline is worn out, it will seriously affect the connection between mine filling and mining procedures, and even affect the normal production of the mine. The study of pipeline wear is of great significance to ensure the safe and stable operation of pipelines. [0003] The prior art provides a device for testing the wear ...
