Mine returning dredging device and method for blast furnace cloth bag pneumatic ash conveying pipeline

Abstract

The invention provides a mine returning dredging device and method for a blast furnace cloth bag pneumatic ash conveying pipeline. The device comprises a mine returning bin, a material collecting hopper arranged above the mine returning bin, a valve arranged on the material collecting hopper, the ash conveying pipeline and a power source device, wherein the ash conveying pipeline and the power source device are connected with the two ends of the mine returning bin correspondingly; the mine returning bin is used for containing blast furnace mine returning particles; the material collecting hopper is used for conveying the blast furnace mine returning particles into the mine returning bin; the valve is used for controlling the material collecting hopper; and the power source device is used for providing power for dredging of the ash conveying pipeline. By utilizing the mine returning dredging device and method for the blast furnace cloth bag pneumatic ash conveying pipe, the problems that ash blockage happens to the blast furnace cloth bag pneumatic ash conveying pipeline easily, and the labor intensity is large when the ash conveying pipeline is cleaned can be solved.

Description

technical field [0001] The invention relates to the technical field of metallurgy, and more specifically, to a device and method for dredging the ore return of a blast furnace cloth bag pneumatic ash conveying pipeline. Background technique [0002] At present, the blast furnace gas bag dust removal system adopts a dense-phase pneumatic ash conveying system. The ash conveying pipeline is prone to clogged ash, the inner wall of the pipeline is thickened, and the texture is hard. The bag ash often falls to the ground, and the system is paralyzed for a long time. A large amount of labor force, thus resulting in greater labor intensity. [0003] In order to solve the above-mentioned problem that the ash conveying pipeline of the furnace gas bag dust removal is prone to be clogged with ash, the present invention provides a dredging device for returning ore to the ash conveying pipeline of the blast furnace bag. Contents of the invention [0004] In view of the above problems, ...
