High-reliability pipeline transportation device used at severe cold area

Abstract

The invention relates to a high-reliability pipeline transportation device used at a severe cold area. The high-reliability pipeline transportation device comprises a connecting pipe and a fixing box;the fixing box takes the shape of a cylinder, is arranged in the connecting pipe and is coaxial with the connecting pipe; the external diameter of the fixing box is less than the internal diameter ofthe connecting pipe; the fixing box is fixedly connected with the inner wall of the connecting pipe; a stirring mechanism and two auxiliary mechanisms are arranged on the fixing box; the two auxiliary mechanisms are arranged at the two ends of the fixing box separately; and the stirring mechanism comprises a power component, a rotary shaft, two bearings,two movable pipes and two stirring components. The high-reliability pipeline transportation device realizes the function of stirring slurry in the connecting pipe through the stirring mechanism to prevent slurry from precipitation to avoid influence to slurry transportation and also realizes the slurry antifreezing function through the auxiliary mechanisms.

Description

technical field [0001] The invention relates to the field of pipeline transportation, in particular to a highly reliable pipeline transportation device used in severe cold regions. Background technique [0002] Pipeline transportation is a long-distance transportation method of liquid and gas materials using pipelines as a means of transportation. It is a transportation method that specifically transports petroleum, coal and chemical products from the production site to the market. It is the backbone of the unified transportation network. special components. [0003] When transporting slurry liquid fluids such as coal slurry through pipelines, in the case of reduced transport volume and slow flow rate, various inhomogeneous flow states will appear, and even solid deposition will occur, which reduces the stability of slurry flow. Not only that, When the pipeline is installed in a cold region, it is also easy to freeze the slurry, resulting in the abnormal flow of the slurry ...
