Description

Technical Field

[0001] The utility model relates to the technical field of boiler processing equipment, in particular to a coating drying device for boiler pressure-bearing components. Background Art

[0002] A boiler is an energy converter that utilizes the heat released by fuel combustion or other thermal energy to heat water or other fluids to specific parameters. It consists of two main components: a pot and a furnace. During the boiler manufacturing process, a coating is typically applied to the exterior of the pressure-bearing components to extend their service life.

[0003] Chinese patent document CN218742993U discloses a coating drying machine device, comprising a frame, a transmission mechanism, and a drying mechanism. The transmission mechanism is arranged at the bottom of the frame, and includes a transmission belt and a power mechanism for driving the transmission belt to rotate. The transmission belt is composed of a plurality of mesh plates. The drying mechanism is arranged at the top of the frame, and includes a housing and a plurality of heating boxes arranged side by side in the housing. The housing is evenly distributed with a plurality of fans, and the air outlets of the fans are connected to an air inlet pipe and / or an air outlet pipe. The utility model drives the transmission belt to rotate through a power mechanism. The transmission belt is composed of a plurality of mesh plates and is used to place a current collector coated with slurry.
