Spraying device for pressure container

The utility model relates to the field of spraying devices, in particular to a spraying device for a pressure container. Comprising a bottom plate, a rotating disc is rotatably arranged at the upper end of the bottom plate, a driving device for driving the rotating disc to rotate is arranged on the bottom plate, a tray concentric with the rotating disc is placed at the upper end of the rotating disc, a plurality of vertical rods are evenly and fixedly distributed on the circumference of the upper end of the rotating disc, and an outlet flange at the lower end of a pressure container is located on the tray; a spraying device is slidably arranged on the bottom plate on the right side of the pressure container. According to the pressure vessel spraying device, the spraying quality can be improved, the spraying efficiency is high, the labor intensity of workers can be reduced, operators can be prevented from inhaling paint and injuring the bodies, and meanwhile the spraying cost of the pressure vessel is reduced.
