Embodiment Construction
[0011] exist figure 1 In the transportation pipeline 2, a plurality of pipeline magnetic fluid propulsion devices 1 are connected in series by means of flange connection at certain intervals to form a transportation pipeline. The installation interval of the pipeline type magnetic fluid propelling device 1 is determined according to calculation. The entire transportation pipeline is closed except for the loading point and the discharge point. The horizontal arrow line in the figure is the moving direction of the conductive liquid and the loose material 3, and the vertically downward arrow line is the direction of the magnetic force lines of the magnetic field. The entire conveying pipeline is filled with conductive liquid, and the conductive liquid in the pipeline magnetic fluid propulsion device 1 is subjected to the action of electromagnetic force and carries the loose material 3 to move rightward to the end and then discharged. A plurality of pipeline-type magnetic fluid ...

The invention relates to transportation of loose materials, in particular to a magnetic fluid transportation mode for loose materials. The magnetic fluid transportation mode is mainly used for pipeline-type transportation of the loose materials, and can realize long-distance closed non-mechanical transmission type transportation of the loose materials. The transported loose materials are mixed with conducting fluid with certain conductivity according to a certain proportion, the transported loose materials and the conducting fluid are put in a closed pipeline excluding a loading point and an unloading point, and a pipeline-type magnetic fluid propulsion device is serially connected every a certain distance. Two electrodes are symmetrically mounted on the inner wall of each pipeline-type magnetic fluid propulsion device and connected with a positive pole and a negative pole of a direct-current power source respectively, and electric current flows through in the conducting fluid in contact with the pipeline-type magnetic fluid propulsion devices. The fluid in the pipeline-type magnetic fluid propulsion devices is put in a magnetic field generated by permanent magnets or electromagnets. The conducting fluid can move under the action of electromagnetic force, and the loose materials mixed with the conducting fluid is impacted by the conducting fluid to move with the same at the same time, so that the purpose of long-distance closed transportation of the loose materials through the pipeline is achieved.
Description
technical field [0001] The invention relates to a magnetic fluid transportation mode of loose materials, which is mainly used for pipeline transportation of loose materials. Background technique [0002] At present, the transportation of lump coal, fine coal, ore, mineral powder and different types of loose materials in other industries mainly adopts mechanical transmission transportation methods, such as scraper conveyors, belt conveyors, screw conveyors, and vehicle transportation. Wait. These different transportation methods have some problems, such as low energy efficiency, short transportation distance, high transportation cost, and environmental pollution due to leakage of materials during transportation. Contents of the invention [0003] In order to realize the long-distance enclosed non-mechanical transmission of loose materials, the invention provides a magnetic fluid transportation method for loose materials. [0004] The solution adopted by the present invent...
