Description

Technical Field

[0001] This utility model belongs to the field of slag flushing pump technology, and particularly relates to a connection device for slag flushing pumps. Background Technology

[0002] During operation, thermal power plant boilers generate a large amount of ash and slag, which is typically discharged into the slag pit through slag channels. To ensure the unobstructed flow of the slag channels and the effective discharge of ash and slag, thermal power plants usually use flushing water to flush the accumulated slag into the slag pit. As the core equipment of the flushing system, the flushing pump plays a crucial role in supplying flushing water to the boiler slag channels.

[0003] However, since circulating water is typically used for slag flushing, a large amount of ash and slag gradually accumulates inside the clear water tank after prolonged operation. This accumulated slag not only causes turbidity in the boiler slag ditch water but also affects the normal operation of the slag flushing pump. Especially when the boiler is not completely shut down, it is impossible to thoroughly clean the slag inside the clear water tank, leading to an increasing amount of ash and slag inside the tank, which seriously affects the safe operation of the slag flushing system in thermal power plants.

[0004] Existing slag flushing pump connection devices have certain limitations in design and function, and cannot effectively solve the problem of cleaning slag accumulation inside the clear water tank. Therefore, there is an urgent need for a connection device for slag flushing pumps that can clean slag accumulation inside the clear water tank during boiler operation, ensuring the safe and stable operation of the slag flushing system.
