Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of combustor, specifically is a double partition fireproof combustor. BACKGROUND

[0002] The combustor is a device that sprays fuel and air in a certain way and mixes and burns. The combustor is divided into industrial combustor, combustion machine, civil combustor and special combustor according to type and application field. It is made of corrosion-resistant and high-temperature-resistant materials such as stainless steel or titanium. The function of the combustor is to atomize the sample by flame combustion. The atomized test solution enters the combustor, and under the action of flame temperature and flame atmosphere, it goes through drying, melting, evaporation, dissociation and other processes to produce a large number of ground state atoms, as well as some excited state atoms, ions and molecules.

[0003] In order to ensure the safety of the system, potential dangers such as fuel leakage, electrical element spark, gas and air mixing and accidental ignition may occur when the combustor is not in use. The combustor needs to be partitioned for fire prevention, mainly to cut off the supply of gas. The existing combustor usually controls the passage of gas to be partitioned when not in use. However, the partitioning tool is prone to plastic deformation when partitioning the gas pipeline for a long time, resulting in a gap between the partitioning tool and the gas pipeline, incomplete partitioning of the gas pipeline and the possibility of gas leakage.

[0032] Further, the combustor comprises a driving moving piece, a sealing piece and an elastic extruding piece. Figure 5 Figure 6 The driving moving piece comprises a driving shaft 4 rotatably installed on the air outlet pipe 2, one end of the driving shaft 4 penetrates the air outlet pipe 2 and is rotatably connected to a connecting sleeve 6 rotatably installed in the air outlet pipe 2 through a bevel gear set 5, the connecting sleeve 6 is internally connected to a plug-in barrel 7 away from the driving shaft 4, and the plug-in barrel 7 is slidably connected to the inner wall of the air outlet pipe 2.
