Simulation experiment set for filling pipeline wear

Abstract

The invention provides a simulation experiment set for filling pipeline wear. The simulation experiment set comprises a worktable and a filling pipe, wherein the worktable comprises a tabletop and a support frame; a motor is arranged on the support frame under the tabletop; and the motor is provided with a variable-frequency governor. A lower sealing plate is fixed on the tabletop; an assembling hole which is formed in the middle of the lower plate penetrates through the tabletop; a vertical filling pipe is arranged on the lower sealing plate; an upper cover plate is arranged on the upper end of the filling pipe; and the upper cover plate and the lower sealing plate are connected with each other outside the filling pipe by use of a vertical pull rod. A rotating shaft coaxial with the filling pipe is arranged in the filling pipe and matched with the assembling hole. A rotating blade is arranged on the rotating shaft; and the lower part of the rotating shaft is connected with the motor after extending out of the table top. The simulation experiment set for filling pipeline wear is capable of performing simulation wear experiments on pipelines different in pipe diameter, wall thickness and material, and meanwhile, capable of realizing the simulation of different proportions and flow velocities of slurry; and the simulation experiment set is reusable, and has the advantages of simple and convenient operations, low experiment cost, small floor area of test instruments and the like.

Description

technical field [0001] The invention relates to a simulation experiment device, in particular to a simulation experiment device for coal mine filling pipeline abrasion. Background technique [0002] In mine filling, the pipeline pressure is high and the slurry flow rate is fast, so the slurry wears heavily on the filling pipeline. The selection and replacement of filling pipelines in mines basically depends on on-site monitoring and experience. The selection of mine filling pipelines was originally based on the experience of similar transmission pipelines, but the selection of mine filling pipelines has its own particularity. Compared with traditional pipeline transportation materials, mine filling materials have complex composition and large difference in particle size, and the form of pipeline wear is essentially different from that of traditional petroleum and other materials.

AI Technical Summary

Problems solved by technology

[0003] At present, mine filling pipe wear test devices mainly include the filling ring pipe simulation test device and the roller machine used in the Anglo-American test of the gold mine in Wiltasland. The filling ring pipe simulation test device has many equipments, and the filling pipe needs to be long and High installation requirements, many filling materials, huge equipment and difficult refueling

In order to prevent the mortar from rotating with the filling pipe, the drum machine used in the Anglo-American test of the Wiltaslan gold mine should not be too high, generally not exceeding 0.8m / s, which can only simulate the wear of different materials on the pipe, and cannot Simulating the relationship between pipe wear and slurry conveying speed
