Description

Technical Field

[0001] The utility model relates to the technical field of burners, in particular to a flame spraying tube of a high-temperature kiln electric furnace burner. Background Art

[0002] Burner is a general term for devices that spray 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 titanium. The function of the burner is to atomize the sample through flame combustion. The atomized test solution enters the burner, and under the action of the flame temperature and flame atmosphere, it 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. A well-designed burner should have the performance of high atomization efficiency, low noise, and stable flame to ensure high absorption sensitivity and measurement precision.

[0003] After searching, Chinese patent document application number 202211629387.8 discloses a high-temperature kiln electric furnace burner flamethrower tube, which includes a bottom plate and a protective mechanism; universal wheels are provided at the four corners of the bottom of the bottom plate, a burner body is provided above the bottom plate, and a support plate is provided below the burner body; the protective mechanism is provided on one side of the burner body, and the protective mechanism includes a tube body, a protective cover and heat dissipation fins, one side of the burner body is connected to the tube body, and the other side of the burner body is provided with a protective cover. The high-temperature kiln electric furnace burner flamethrower tube provided by this invention solves the problem that some existing high-temperature kiln electric furnace burner flamethrower tubes are usually directly exposed to the outside world without any protective measures, resulting in the high temperature emitted by the flamethrower tube causing the surrounding temperature to rise sharply, thereby affecting the surrounding personnel and failing to meet the needs of users at this stage.

[0004] However, this device has certain defects. When the flamethrower on the existing flamethrower tube is in use, the range of the fire sprayed from the nozzle cannot be adjusted arbitrarily according to the current environment, which is inconvenient to use. Therefore, we need to design a high-temperature kiln electric furnace burner flamethrower to solve the problem that the range of the fire sprayed from the flamethrower on the flamethrower tube is not easy to adjust at will.
