Mechanism with multiple discharge ports for deliverying pressurized powder in thick phase

Abstract

A pressurizing delivering apparatus with multiple discharge ports for delivering the condensed powder has a powder pressurizing tank, which has a feeding inlet connected via valve to feeding pipeline, an air pressuring pipeline and a pressure balance pipeline on its lateral wall, lower fluidized wind pipe, two or more branch pipelines at the lower end of said pressurizing tank for delivering the power, and two or more loosening devices for said branch pipelines and communicated with N2 pipeline.

Description

technical field [0001] The invention belongs to the technical field of dense-phase conveying of powder materials, and in particular relates to a pressurized dense-phase conveying device for powder with multiple outlets. technical background [0002] Powder pneumatic conveying technology is a method of using gas energy to transport powder materials, which has a history of more than 100 years. Theory and practice have proved that powder pneumatic conveying technology has advantages over mechanical conveying, such as simple equipment, flexible layout, easy dust collection, etc. It has been widely used in electric power, metallurgy, chemical industry, building materials, light industry, food and other industries. Wide range of applications. Generally speaking, the pneumatic conveying of pulverized coal and general solid particles can be realized in a wide range of flow patterns, and the flow pattern is mainly affected by some factors including flow velocity, particle size, grav...
