Description

Technical Field

[0001] The utility model relates to the technical field of fire retardant coatings, in particular to a uniform spraying device for the construction of fire retardant coatings on the surface of steel structures. Background Art

[0002] Fire retardant coatings are also called flame retardant coatings. Applying this type of coating on the surface of certain flammable materials in buildings can improve the fire resistance of flammable materials, or slow down the spread of flames, prevent combustion within a certain period of time, control the development of fire, and provide time for people to extinguish the fire. This type of coating is called fire retardant coatings or flame retardant coatings in the construction industry.

[0003] For example, the Chinese patent publication number CN217615609U, "A Uniform Spraying Device for the Construction of Fire Retardant Coatings on Steel Structure Surfaces", discloses a uniform spraying device for the construction of fire retardant coatings on steel structure surfaces, including a base, a lifting seat fixedly connected to the top of the base, a threaded rod rotatably connected to the inner wall of the lifting seat, a lifting platform slidably connected to the inner wall of the lifting seat, the inner wall of the lifting platform is threadedly connected to the outer wall of the threaded rod, a motor A fixedly connected to the top of the lifting seat, the output end of the motor A is fixedly connected to one end of the threaded rod, and the outer wall of the lifting platform is fixedly connected to a first connecting plate. When spraying, the first connecting plate will move with the lifting platform, and the annular tube on the first connecting plate will also move with it. While the annular tube moves, the hot air machine will draw in and heat the external air, and the heated air will be transported into the annular tube through the air duct, and then sprayed from the hot air nozzle to the steel pipe, so as to air-dry the paint just sprayed on the surface of the steel pipe, thereby achieving the effect of rapid solidification of the paint.

[0004] However, in actual use, the steel structure material is sprayed by raising and lowering the paint nozzle. There is a lack of shielding during the spraying process. The part of the fire retardant paint spray not sprayed on the surface of the steel structure material may be ejected far away, causing pollution to the environment. It is not convenient to protect the spraying area at any time when the paint nozzle is raised and lowered for spraying, so as to prevent the fire retardant paint spray from spreading.
