Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ash conveying pipes, in particular to a pneumatic ash conveying pipeline anti-blocking mechanism. Background Art

[0002] Pneumatic ash conveying pipe is an important transport component in the pneumatic ash conveying system. It uses the energy of airflow to transport granular materials such as coal ash and dust in the airflow direction in a closed pipeline. According to the density of particles in the pipeline, pneumatic ash conveying pipe can be divided into dilute phase ash conveying and dense phase ash conveying. The former is suitable for short-distance transportation, while the latter is suitable for longer distances. Pneumatic ash conveying pipe has the advantages of environmental protection, safety, and high efficiency, and is widely used in many industries such as electricity, steel, chemical industry, and building materials.

[0003] The pipeline anti-blocking structure of the pneumatic ash conveying system recorded in the patent document with announcement number CN219044696U, by quickly pushing the movable shaft in the fixed pipe, drives the movable plate at one end of the movable shaft to move and drives several pointed cones on the surface of the movable plate to move synchronously. After the movable plate is pushed out, the movable shaft is quickly pulled outward, so that the movable plate drives the pointed cones to quickly return to the center, and the deposited dust will have an immovable force due to inertia, so the deposited ash will be separated from the surface of the movable plate, and then the movable shaft is moved back and forth multiple times, and multiple pointed cones will scatter the dust so that the dust will no longer accumulate together, and then the scattered dust can be taken away together during the next ash conveying. At the same time, it can also be used in the ash conveying process to scatter the block dust, reduce its weight, and facilitate it to be taken away by compressed air, thereby solving the problem of dust accumulation at the corners of the ash conveying pipe. The pipeline anti-blocking structure of the pneumatic ash conveying system cannot timely understand whether the ash conveying pipe is blocked, thereby delaying the work progress.

[0004] Based on this, a pneumatic ash conveying pipeline anti-blocking mechanism is now provided to eliminate the drawbacks of the existing device. Utility Model Content
