Abstract

A fluid conveying device is disclosed. In the fluid conveying device, the first gradual change section is located at the first end of the inner tube wall close to the input fluid, and has a first length and a first cross section in the longitudinal direction of the vortex flow tube. A cross-section smoothly transitions from a circle with a radius R to a blade shape while the first gradual change section is twisted at a first predetermined angle in the longitudinal direction, and the first cross-section changes nonlinearly in the longitudinal direction along with the first gradual change section Rotate the first predetermined angle, the third cross-section along with the second transition section in the longitudinal direction of the third predetermined angle twisted smoothly from the shape of the blade to a circle with a radius R, the third cross-section along with the second gradual change The segments are twisted at a third predetermined angle non-linearly and gradually in the longitudinal direction, and the cross-sectional area of ​​the third cross-section remains constant. At least one vortex tube is provided between the plurality of fluid delivery tubes, one end of which is connected to the second transition zone The section is for receiving the vortex flow fluid containing suspended solid particles, and the fluid delivery pipe has a fourth cross-section.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation, in particular to a fluid delivery device. Background technique [0002] Pipeline transportation is a method in which solids are crushed into powder, an appropriate amount of liquid (or gas) is prepared into slurry (or gas powder mixture), and transported through pipelines. Pipeline transportation has the characteristics of large transportation volume, small land occupation, low energy consumption, safety and reliability, no pollution, no climate influence, short transportation distance (compared to truck transportation), and low cost. [0003] According to the carrier used, it can be divided into liquid delivery pipeline and air delivery pipeline. The carrier of the liquid delivery pipeline is generally water. Air delivery pipelines use compressed air as a carrier. At present, the long-distance and large-capacity solid slurry pipelines all adopt the slurry transportation proces...
