Description

Technical Field

[0001] The utility model relates to the technical field of metal product industry, in particular to an online dust cleaning tool for a continuous heat treatment furnace for steel wire without stopping the furnace. Background Art

[0002] The steel wire heat treatment pickling and phosphating continuous production line is a process of transforming the steel wire into a sorbite structure and pickling and phosphating the steel wire surface to meet the structure and surface state required for advanced drawing and deep processing of the steel wire. Because the surface of the steel wire before entering the heat treatment furnace is adhered with the drawing powder and other debris used in the previous drawing, after the steel wire enters the furnace, these debris will fall down and gather in the furnace with the flow of flue gas and be brought into the furnace's exhaust system, accumulating on the surface of the heat exchanger, causing unstable furnace pressure. The longer the time, the more accumulation, which will reduce the heat exchange efficiency and increase energy consumption. In severe cases, it will cause the furnace pressure to be too high and uncontrolled, resulting in various defects in the quality of the steel wire in the furnace, resulting in waste, and the furnace has to be stopped for cleaning, and the loss caused by stopping the furnace for cleaning is also large;

[0003] In this regard, the Chinese utility model patent with the authorization announcement number CN215723221U discloses a boiler non-stop online ash cleaning device, which relates to the field of boilers. It comprises a boiler burner, the outer side of the boiler burner is provided with a blast duct and a gas pipeline, the inside of the boiler burner is provided with a plurality of guide vanes, the outer side of the boiler burner is installed with a ball valve, the bottom ends of the blast duct and the gas pipeline are flush and have the same diameter, the burner cleaning device is installed on the outside of the burner, and the guide vanes are installed in a ring-shaped distribution in the combustion area of ​​the inner cavity of the boiler burner. The utility model adopts the design of the ball valve. When it is necessary to clean the inside of the boiler burner, the other valves on the branch pipe of the boiler burner are closed, and the ball valve is opened. The blockage inside the boiler burner is cleaned from the outside with a steel chisel. After the ash and blockage inside the boiler burner are cleaned, the ball valve is closed, thereby alleviating the blockage degree of the boiler burner, improving the boiler efficiency, and reducing energy waste.

[0004] The existing online non-stop furnace cleaning device can clean most of the dust on the heat exchanger. However, the top area of ​​the heat exchanger is a cover plate. The cover plate cannot be lifted out for cleaning due to high temperature without stopping the furnace, so the dust on the top of the heat exchanger cannot be cleaned online. For this reason, we propose an online cleaning tool for the steel wire continuous heat treatment furnace without stopping the furnace to solve the above problem. Utility Model Content
