Problems solved by technology

[0003] The present invention designs a multi-stage demagnetization system for long-distance iron ore concentrate pulp pipelines with complex terrain. The technical problem it solves is that after the slurry with large magnetism enters the long-distance pipeline, the pulp in the pipeline is stagnant due to external factors. When in the state, magnetic agglomeration is prone to occur, and finally forms clusters in the conveying pipeline, causing blockage of the conveying pipeline, and finally affecting normal production and other defects

Abstract

The invention relates to a complex-terrain long-distance iron ore concentrate conveying pipeline multi-level demagnetizing system, which comprises a concentration machine, a bottom stream pump and a plurality of pump stations, wherein the output end of the concentration machine is connected with the input end of the bottom stream pump through a pipeline, the output end of the bottom stream pump is sequentially connected with the plurality of pump stations through pipelines, and the pipeline between the concentration machine and the bottom stream pump is provided with a demagnetizing device. The demagnetizing system can effectively demagnetize the magnetic iron ore slurry, and can prevent the magnetic agglomeration of the magnetic ore slurry inside the pipeline from causing the blockage of the pipeline.

Description

technical field [0001] The invention relates to the field of long-distance iron concentrate slurry pipeline transportation with complex terrain, in particular to a multi-stage demagnetization system for iron concentrate pipelines. Background technique [0002] In the current slurry pipeline transportation, due to the iron concentrate beneficiation process (weak magnetic separation, strong magnetic separation, etc.) and the long-distance pipeline transportation process, the iron concentrate slurry will bring certain magnetism. For long-distance iron ore slurry transportation pipelines with complex terrain, strong magnetism is not allowed for iron ore slurry. Otherwise, once the pipeline fails and the slurry is in a non-flowing state during the transportation process, magnetic agglomeration will be formed due to magnetism. Make the particles thicker and easily deposit in the pipeline, causing serious blockage of the pipeline, seriously affecting production or bringing major ec...
