Description

Technical Field

[0001] The utility model relates to the technical field of boiler burners, in particular to a wind shielding device for a boiler burner. Background Art

[0002] A boiler burner refers to a burner used on a boiler. A boiler burner is the most important equipment among the auxiliary equipment of an oil-fired or gas-fired boiler. A burner is a general term for a device that sprays fuel and air in a certain way for mixed combustion. Burners are divided into industrial burners, burners, civil burners, and special burners according to their types and application areas. They are mostly made of corrosion-resistant and high-temperature resistant materials such as stainless steel or aluminum. The function of the burner is to atomize the fuel through flame combustion. The atomized fuel enters the burner and, under the action of the flame temperature and flame atmosphere, undergoes processes such as drying, melting, evaporation, and dissociation to produce a large number of ground-state atoms, as well as some excited-state atoms, ions, and molecules.

[0003] The existing windshield device has a relatively simple structure and poor windshield effect, which easily causes the atomized fuel inside to leak, making it impossible for workers to take timely response measures, causing the working environment to be polluted and endangering the health of workers.

The air shield frame includes a filter core and a filter door, and the filter door is fixedly connected to the frame opening of the air shield frame by bolts, and the filter core is located inside the air shield frame.

[0007] As a further solution of the present invention, the sealing box is rotatably connected to a box door on one side close to the filter door, and the air volume regulating cylinder is integrally connected to a side frame on one end close to the regulating blade. A filter frame is provided on one side of the side frame, and the filter frame is fixedly connected to the side frame by bolts.
