Abstract

This invention relates to pipeline transportation. The purpose of the invention is to increase the service life. The pipeline contains installed in the lower part of the pipe 1 and in pairs distributed along its length, the partitions 2, which are made of lattice. The cross section of the first cells along the flow of the partition 2 increases from its ends to the center, and the second is equal to the cross section of the central cells of the first partition 2. 2 Il.

The invention relates to pipeline transport, in particular to pipelines for the hydrotransport of bulk materials.

The purpose of the invention is to increase the service life.

On c) this year. 1 shows the pipeline, top view, section; in fig. 2 shows section A-A in FIG. 1. The pipeline consists of pipe 1 and transverse partitions 2 in the form of paired grids, spaced from each other at a distance of 0.03-0.05 of the pipe diameter, rigidly mounted (by welding or others) on strips or rods 3, inserted to the lower part of the pipe and fastened to its walls., The size of the holes in the central part of the first grid is slightly larger than the size of its peripheral holes and equal to the size of the holes in the second grid.

The device works as follows.

When feeding the slurry into the pipe, 1 part of the material being transported is retained by partitions 2 and precipitates to protect its lower part from wear. At the same time

The working section of the pipeline acquires an oval shape, which intensifies the process of mixing in the flow and, consequently, increases its carrying capacity. The characteristics of the flow of the carrier flow through the double partitions 2 determine the uniformity and continuity of the formation of the protective layer along the entire length of the pipe.

Claims (1)

Formula isotopic Pipeline for hydrotransport of bulk materials, containing a cylindrical pipe, in the lower part of which transverse partitions with a concave upper edge are fixed to give an oval shape to the flow section, which are pairwise distributed along the pipe, characterized in that, in order to increase service life, the partitions are made of lattice, at the same time, the first one in a pair, in the course of the flow, the partition wall is made with a flow area of the cells increasing from its ends towards the center, and the second one with a flow area of cells equal to the flow area sweeping the cells of the first partition.
