Embodiment 1

[0038] like figure 1 As shown, a test device for the wear test of the filling slurry conveying pipeline includes a stirring tank 1, a conveying assembly connected to the output end of the stirring tank 1, and a test pipe assembly connected to the output end of the conveying assembly. The test pipe The output end of the assembly is connected to the input end of the stirring tank 1 to recycle the filling slurry, so as to study the wear law of the test pipe assembly with less test material. The conveying component is preferably a frequency conversion slurry pump 5, by controlling the pumping frequency of the frequency conversion slurry pump 5, the research on the pipeline wear of the filling slurry at different flow rates can be realized. The test pipeline assembly includes several interconnected horizontal pipelines 9, elbows, inclined pipelines and vertical pipelines, which can simulate various slurry transportation conditions.

[0039] With such a setting, the research on the...

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 ...
