Description

Technical Field

[0001] The utility model relates to the technical field of metal chromium smelting, in particular to cooling treatment equipment for metal chromium smelting. Background Art

[0002] Metal smelting is a refining technology, which refers to the extraction of metals from ores by roasting, smelting, electrolysis and the use of chemical agents, in order to reduce the impurities contained in the metal or increase a certain component in the metal and refine it into the required metal. During the metal smelting process, the smelting furnace and other equipment need to be cooled. The commonly used cooling method is to circulate cooling water to achieve the cooling purpose. After the cooling water is used for a long time, a large amount of impurities are easily generated inside it, and a large amount of cooling waste water will be generated, resulting in waste.

[0003] For example, an energy-saving cooling device for a smelting furnace for silicon carbide production provided by authorization number CN217604696U includes a smelting furnace body, two left and right distributed support seats are fixedly installed on the bottom end surface of the outer side wall of the smelting furnace body, and the bottom end surfaces of the two support seats are fixedly installed with a fixing frame, and the bottom end surface of the fixing frame is fixedly installed with a fixing box. By placing a liquid nitrogen storage tank inside the fixed box and connecting the liquid nitrogen storage tank with a venting pipe, when the smelting furnace body needs to be cooled, the valve is first opened to allow the liquid nitrogen in the liquid nitrogen storage tank to enter the venting pipe, and then the nitrogen enters the connecting pipe from the venting pipe, so that the connecting pipe guides the nitrogen The nitrogen enters the interior of the two first air outlet pipes, then enters the interior of the two second air outlet pipes, and is discharged through the multiple exhaust pipes on the first air outlet pipe and the second air outlet pipe. The nitrogen passes through the wire mesh during the rising process and contacts the smelting furnace body, so that the nitrogen cools the smelting furnace body to achieve a rapid cooling effect. Although the above-mentioned device can release liquid nitrogen through the liquid nitrogen storage tank to cool the smelting furnace, the above-mentioned device can only quickly cool the bottom of the smelting furnace, while the cooling effect on the top of the smelting furnace is poor, and due to the heavy weight of the liquid nitrogen storage tank, it is very inconvenient to replace the liquid nitrogen storage tank, and a long time of replacement will affect the cooling effect of the smelting furnace.
