Description

Technical Field

[0001] The utility model relates to the technical field of coating spraying equipment, and more specifically to a feeding structure for spraying outdoor intumescent steel structure fireproof coating. Background Technique

[0002] The intumescent steel structure fireproof coating is applied to the surface of combustible substrates to change the combustion characteristics of the material surface and block the rapid spread of fire; or it is applied to building components to improve the fire resistance of the components. Such a special coating is called fireproof coating. When a steel structure building is constructed and used, in order to improve its yield point and strength, fireproof coating will be sprayed on the surface of the steel structure.

[0003] After retrieval, the existing patent (publication number: CN216261593U) discloses a steel structure fireproof coating spraying device. During its use, the fireproof coating is pre-filled into the spraying vehicle for storage, and then the spraying vehicle is pushed to move for position adjustment. The fireproof coating is sprayed onto the surface of the outdoor steel structure building through a nozzle. During the use of the nozzle, the spraying angle of the nozzle can be flexibly adjusted through an angle adjustment mechanism. However, the inventor found the following problems in the process of implementing the present utility model: when the above-mentioned fireproof coating spraying device is used, the coating needs to be pre-injected into the spraying vehicle. In actual production, fireproof coating products are uniformly stored in standard coating barrels. When the above device is used, an additional coating pouring and feeding operation is required. The coating barrel is heavy, and when feeding the coating, there is a defect of large operation labor intensity. Moreover, it takes a long time to pour the viscous coating from the coating barrel into the spraying vehicle, thus reducing the overall efficiency of fireproof coating spraying construction.

[0004] In view of this, the present utility model proposes a feeding structure for spraying outdoor intumescent steel structure fireproof coating to solve these problems. Content of the Utility Model
