Description

Technical Field

[0001] The utility model relates to the technical field of pneumatic ash conveying equipment, in particular to an ash discharge control device for high-pressure pneumatic ash conveying. Background Art

[0002] Existing pneumatic ash conveying devices may cause blockage in the ash conveying pipeline when conveying ash from the ash storage bin to the ash conveying pipeline, and the amount of ash in the ash storage bin cannot be adjusted. During the feeding process, the ash conveying pipeline may be blocked due to excessive ash feeding. Once the ash conveying pipeline is blocked, it needs to be cleaned and unblocked. This not only consumes a lot of manpower, material resources and time, but may also cause damage to the equipment and increase the maintenance cost of the equipment. For example, problems such as pipeline wear and valve leakage may be aggravated by blockage, and blockage of the ash conveying pipeline may also pose a safety hazard. For example, blockage may cause the pressure in the pipeline to increase, increasing the risk of pipeline rupture. Utility Model Content
