Burner and heating device with same

Abstract

The invention relates to the field of machinery, in particular to a burner. The burner comprises a burner shell and a jet nozzle; and the interior of the burner shell is hollow, and openings are formed in the two ends of the burner shell correspondingly, an installing part used for installing the jet nozzle is arranged on the inner wall of the burner shell, a jet hole parallel to the axis of the burner shell is formed in the jet nozzle, and a first through hole is formed in the outer wall of the side, where the installing part is close to an air outlet of the burner, of the burner shell. The invention further relates to a heating device with the burner; the heating device is used for heating an aluminum rod casting platform; the heating device further comprises a supporting frame, whereinthe supporting frame is located horizontally above the aluminum rod casting platform, and is parallel to the aluminum rod casting platform; and the burner is installed on the support frame and corresponds to the horizontal upper portion of a flow groove of the aluminum rod casting platform. The burner and the heating device with the burner have the advantages of being uniform in heating, energy-saving and capable of improving efficiency, and an anti-backfire function is achieved.

Description

technical field [0001] The invention relates to the mechanical field, in particular to a burner and a heating device with the burner. Background technique [0002] As the products of aluminum products become more and more high-end, the quality requirements for round cast aluminum rods are also getting higher and higher. Casting round cast rods with thin segregated layers can not only improve the yield, but also make the extruded products better in quality. it is good. At present, in the aluminum rod casting process, it is usually necessary to heat up the launders of the hot top casting platform and the oil-air sliding casting platform, which can reduce the temperature drop during casting, prevent the segregation layer thickness of the aluminum rod after casting, and improve the surface quality of the casting rod . Existing heating devices generally use soil guns, which have a single heat source and a small heating area. Generally, multiple places need to be baked separatel...

AI Technical Summary

Problems solved by technology

Existing heating devices generally use soil guns, which have a single heat source and a small heating area. Generally, multiple places need to be baked separately, resulting in uneven preheating temperature of the entire platform, which takes a long time and wastes a lot of natural gas; Some platform baking soil guns generally directly feed natural gas and compressed air into the steel pipe, so that the tempering device cannot be installed, and the risk factor is very high
