Problems solved by technology

[0002] Pipeline transportation is one of the best transportation methods for paste and paste-like mud. It is often used to transport various mud such as coal slime, sludge, calcium carbide mud, and papermaking waste mud. However, due to the shear force of the side wall and the mud Due to the friction between the solid component and the conveying pipe wall, there are defects and deficiencies such as large conveying resistance and high conveying cost. It rubs against the wall of the conveying pipe, and the conveying resistance is so large that it is difficult to use pipelines for conveying. The relevant industry has to use belt conveyors for conveying, which not only emits a large amount of volatile gases into the atmosphere, but also produces a large amount of dust, causing serious air pollution

Abstract

The invention discloses a method for conveying mud by an air cushion, a fluid injector and a mud conveying system. The mud conveying system comprises a slurry conveying pump 5, a high pressure gas source device 6, the fluid injector 7, a lubricating mud conveying pipe 8, a one-way valve 9 and a mud check valve 10, wherein the slurry conveying pump 5 is sequentially communicated with the mud checkvalve 10, the fluid injector 7, and the lubricating mud conveying pipe 8, the high pressure gas source device 6 is communicated with the one-way valve 9, and the one-way valve 9 is communicated with afluid medium injection port 711 of the fluid injector 7. The method for conveying mud by the air cushion, the fluid injector and the mud conveying system have the advantages that difficult-to-pump mud is conveyed through a pipeline, the conveying resistance is low, and the transportation cost is low.
