Redox duct support

Abstract

The invention belongs to the technical field of non-ferrous smelting and relates to a redox air duct support. The redox air duct support comprises a supporting seat and an air duct hanging hook, wherein a fixing hook is arranged at one end of the air duct hanging hook; a plurality of fixing hooks which are away from the fixing hook at different distances are arranged at the other end of the air duct hanging hook; two parallel air duct supports are arranged on one supporting seat; two redox air ducts are erected on the air duct support in parallel; and the two redox air ducts are hooked by the fixing hooks of the air duct hanging hook. According to the redox air duct support disclosed by the invention, the condition that the redox air duct support is moved in the use process due to influence from factors such as jump of the redox air ducts is avoided.

Description

technical field [0001] The invention relates to miscellaneous copper pyrometallurgy, in particular to a bracket for a fixed anode furnace oxidation-reduction air duct. Background technique [0002] There are currently 4 fixed anode furnaces in the tilting workshop of Guizhou Smelter. After the miscellaneous copper is melted in the furnace, it is necessary to use redox brackets to transfer 4 sets of miscellaneous air delivery pipes to the melt in the furnace, and each two groups extend into the furnace from a charging door. Inside. In production practice, the relative positions of the two groups of conveying air pipes in the same feeding door are basically in the shape of "eight" or inverted "eight". The air pipes are affected by factors such as medium pressure and mechanical force in the copper liquid.

Problems solved by technology

In production practice, the relative positions of the two groups of conveying air pipes in the same feeding door are basically in the shape of "eight" or inverted "eight". The air pipes are affected by factors such as medium pressure and mechanical force in the copper liquid. Irregular movement in the furnace can not effectively stir the copper liquid at the designated position, which will easily cause the burner of the furnace body to be seriously bonded with cold copper, affecting the combustion efficiency of heavy oil, thereby increasing energy consumption; secondly, the splashing of copper liquid can easily cause The cold copper is accumulated, and the air pipe cannot be effectively stirred at the bottom of the copper liquid, which affects the effect of impurity removal and prolongs the operation cycle. A large number of slag outlets are piled up. During the slag discharge operation, it is easy to cause a large area of ​​refractory materials to fall off the slag outlet, resulting in high-temperature melt overflow and seriously endangering personal and equipment safety.
