Description

Technical Field

[0001] The utility model relates to the technical field of soot blowers, in particular to a steam soot blower for a heater. Background Art

[0002] A device used to remove ash from the heating surface of a boiler, usually composed of a sootblower and operating valves and other components, and is commonly used in industrial boilers and large heaters. The steam sootblower uses the high-speed jet impact force of superheated steam to remove ash from the heating surface, and is mostly used in various power plant boilers and large heaters.

[0003] Publication No. CN210291923U discloses a steam soot blower, which starts a first motor, drives a threaded column to rotate, and further drives an air receiving plate to move up and down between a mounting plate and one side of a vertical plate, and drives a folded pipe to move up and down, thereby stretching or compressing a telescopic hose. After adjusting a suitable height, a second motor is started, which drives a rotating shaft to rotate, and further drives a second bevel gear to rotate, so that the meshed first bevel gear rotates, thereby driving a threaded sleeve to rotate, and then drives a movable pipe to move rightward, and then drives the soot blowing pipe to move rightward to adjust the distance from the boiler. At this time, the air receiving hole is connected to an external steam pipe, and a heating resistance wire is started by an external power supply. Steam enters the air receiving plate through the inclined pipe, the telescopic hose and the folded pipe, and then is transported to the movable pipe through the threaded sleeve, and then is heated by the heating resistance wire inside the soot blowing pipe, and finally blown out from the soot blowing pipe. However, the patent still has the following problems in actual use:

[0004] By starting the first motor, the threaded column is driven to rotate, which further drives the air receiving plate to move up and down between the mounting plate and one side of the vertical plate, and drives the folded pipe to move up and down, thereby stretching or compressing the telescopic hose. After adjusting the appropriate height, the second motor is started at this time, which drives the rotating shaft to rotate, and further drives the second bevel gear to rotate, so that the meshing first bevel gear rotates, thereby driving the threaded sleeve to rotate, and then drives the movable pipe to move to the right, and then drives the soot blowing pipe to move to the right to adjust the distance from the boiler. However, when soot blowing on a large heater, although the steam contains water vapor, which can adsorb dust, when the steam comes into contact with dust, due to the large impact force of the steam, it is easy for some dust to diffuse, thereby causing some dust to enter the external air, which will cause air pollution.

[0005] A steam sootblower for a heater is proposed in order to solve the above-mentioned problems. Utility Model Content
