Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ash conveying, in particular to a pipe bottom dredging structure of a pneumatic ash conveying system. Background Art

[0002] Pneumatic ash conveying, also known as air flow conveying, uses the energy of air flow to transport granular materials along the direction of air flow in a closed pipe. It has a simple structure and is easy to operate. It is a specific application of fluidization technology.

[0003] The existing pneumatic ash conveying system lacks a dredging structure for its pipelines. Under the action of gravity, part of the ash will gradually settle to the bottom of the pipeline, eventually leading to blockage. Manual pipe cutting is required for dredging, which increases the labor intensity of workers and affects the ash conveying process. Utility Model Content
