Powdery solid conveying pipeline and device and working method thereof

Abstract

The invention discloses a powdery solid conveying pipeline and device and a working method thereof. The powdery solid conveying pipeline comprises a conveying pipeline, a first flange plate and a second flange plate. A plurality of branch pipelines are arranged on the conveying pipeline at intervals, and the first flange plate and / or the second flange plate are / is installed on the branch pipelines. The first flange plate is hermetically connected with the branch pipelines. The second flange plate comprises an end plate and a telescopic cleaning device, the end plate can be connected with the branch pipelines, the cleaning device is installed on the inner surface of the end plate, and the cleaning device can stretch into the conveying pipeline. During normal use, the branch pipelines can be blocked through the first flange plate, normal conveying of solid powder is guaranteed, and when the conveying pipeline is blocked, the blocked part of the conveying pipeline can be dredged by replacing with the second flange plate. It can be seen that the powdery solid conveying pipeline is convenient to clean, the integrity of the conveying pipeline can be guaranteed, the dismounting and mounting workloads are small, and therefore the investment is small.

Description

technical field [0001] The invention belongs to the technical field of industrial transportation, and in particular relates to a powdery solid transportation pipeline, a device and a working method thereof. Background technique [0002] When conveying powdery solids through pneumatic pipelines, with the change of the flow rate (flow rate) of the conveyed solids, the change of the ambient temperature, the change of the moisture content of the solids and other factors, the conveyed powdery solids will be blocked and compacted in the pipeline. After the pipeline is blocked, it is mostly carried out by poking the pipeline with external force, and it is difficult to clean it. The traditional way of dredging is poor, and it is difficult to dredge serious blockages. In the end, the only way to dredge the pipeline is to destroy it, resulting in high pipeline costs. Contents of the invention [0003] In order to solve the problems raised in the above-mentioned background technolog...
