[0002] In the process of surface maintenance of atmospheric pressure boilers, spraying devices are widely used to perform surface maintenance treatment on atmospheric pressure boilers. Atmospheric pressure hot water boilers, also known as unpressurized hot water boilers, belong to the category of domestic boilers. An atmospheric pressure hot water boiler is a type of unpressurized hot water boiler with an vent to the atmosphere at the top, and the boiler body is always operating at atmospheric pressure. Its main feature is that the boiler is not pressurized, so there are no safety hazards. It is mainly used for heating and hot water production, and it is one of the more common types of boilers. Spraying devices are also used in the surface maintenance of atmospheric pressure boilers.

Repeat the above process to move rack 19 to one side of the second gear 15. The controller controls the second cylinder 16 to reciprocate, driving the second gear 15 to rotate, causing the rigid tube 11 to rotate. According to the size of the boiler, the corresponding ball valve 13 is opened, allowing the nozzle 14 to spray the boiler, improving the spraying effect. During spraying, the controller starts the exhaust fan 37 to drive the toxic molecules of the paint into the treatment box 25. After being filtered by the activated carbon filter plate 27, they are discharged. The activated carbon filter plate 27 can then be slid upwards for replacement. At the same time, the controller controls the fan 29 to work, blowing the heat generated by the heating copper tube 32 and the heating head 33 into the boiler after being filtered by the filter screen 31 for drying, improving work efficiency. The filter screen 31 can also be slid upwards to remove and replace it.
