Aluminum alloy industrial kiln burner and lining material

Abstract

The invention discloses an aluminum alloy industrial kiln burner and a lining body material. The aluminum alloy industrial kiln burner comprises a gas gun, a burner body, a heat storage box, a burner nozzle, a thermal imager, a rotating assembly, a gas conveying valve, a filtering assembly and a mounting base; the rotating assembly is mounted on one side of the end face of the top of the mounting base, and the burner body is installed above the top of the rotating assembly; the gas gun is arranged at one end of the burner body; the burner nozzle is installed at one end of the gas gun in a connected manner, and the heat storage box is installed on the outer side of the burner nozzle; and the thermal imager is arranged above the top of the burner body. According to the aluminum alloy industrial kiln burner of the invention, the effect of uniform temperature distribution in an industrial kiln can be effectively achieved, then aluminum alloy is effectively and rapidly melted, and waste caused by aluminum alloy oxidation and burning loss is reduced; and meanwhile, conveyed gas can be filtered and purified by the filtering assembly, to effectively remove impurities in the gas, and therefore the combustion quality can be improved.

Description

technical field [0001] The invention relates to the technical field of industrial kiln burners, in particular to an aluminum alloy industrial kiln burner and a lining material. Background technique [0002] With the rapid development of the national economy, the demand for aluminum alloys in my country has increased rapidly. In the existing technology, aluminum ingots or waste aluminum are used as raw materials to be put into the melting furnace first, and the nozzles are sprayed with fire to melt them. The molten aluminum enters the subsequent holding furnace, casting and other processes. [0003] The flame of the traditional regenerative burner is concentrated. On the one hand, because the area of ​​the flame burning through the furnace is too small, the temperature uniformity of the furnace is not high, which affects the effect of convective heat transfer of the flame, and also leads to the low efficiency of aluminum alloy melting. The energy-saving effect is not outstand...

AI Technical Summary

Problems solved by technology

[0003] The flame of the traditional regenerative burner is concentrated. On the one hand, because the area of ​​the flame burning through the furnace is too small, the temperature uniformity of the furnace is not high, which affects the effect of convective heat transfer of the flame, and also leads to the low efficiency of aluminum alloy melting. The energy-saving effect is not outstanding. On the other hand, there must be a large enough furnace space to accommodate the expansion of the flame, which is unfavorable to the design of small industrial furnaces;

[0004] Moreover, in recent years, although the regenerative heating burner designed by using the diffusion combustion mechanism has made up for some of the above problems, it has problems such as the need for high calorific value gas, incomplete combustion, relatively high CO content in flue gas, and relatively large burner volume. The disadvantages also lead to its inability to be widely used. Therefore, it is necessary to design an aluminum alloy industrial kiln burner and lining material
