Description

Technical Field

[0001] The utility model relates to the technical field of steam soot blowers, in particular to a steam soot blower with an easy-to-replace nozzle. Background Technique

[0002] A steam soot blower is a device used to remove ash deposits and slag on the heating surface of a boiler or heat exchanger. It uses the steam from the boiler itself as the medium, and impacts and removes the ash deposits by spraying steam at high speed, so as to keep the heating surface clean, improve the thermal efficiency, and prevent the decline of boiler efficiency and insecurity.

[0003] Chinese Patent Authorization Publication No. CN 220892271 U discloses a steam soot blower with an easy-to-replace nozzle, which includes a protective cover and a steam connection pipe penetrating through one side of the protective cover. One end of the steam connection pipe is connected with a telescopic hose, and one end of the telescopic hose is provided with an installation pipe. On both the upper and lower sides of the steam connection pipe on one side of the protective cover, there are fixed rods. One end of the fixed rod is provided with an adjusting rod near the fixed sleeve. The outside of the installation pipe is installed with an installation sleeve, one end of the installation sleeve is installed with a nozzle, and an installation rod penetrates through the outside of the installation sleeve. A groove is opened inside the installation sleeve, and a pressing plate is arranged inside the groove. Through the operation of the second electric telescopic rod arranged at one end of the installation rod, the pressing plate inside the groove will move towards the position of the nozzle, thereby pressing the nozzle, and the limiting rod is inserted into the limiting hole opened outside the nozzle, so as to ensure the stability of the installation of the nozzle.

[0004] The above-mentioned prior art fixes and presses the nozzle by pushing the pressing plate with an electric telescopic rod. When the steam soot blower blows soot on the boiler, the nozzle needs to be extended into the boiler for operation. Usually, the boiler is in operation during soot blowing, and the electric telescopic rod will cause damage to the internal electronic components at high temperature, which will cause the nozzle to fall off or the nozzle cannot be replaced, greatly increasing its cost. Therefore, there is an urgent need for a steam soot blower with an easy-to-replace nozzle. Content of the Utility Model
