Description

Technical Field

[0001] The utility model relates to the technical field of electrolytic aluminum production technology, in particular to a residual anode cooling device in electrolytic aluminum production. Background Art

[0002] Electrolytic aluminum is aluminum obtained by electrolysis. Modern electrolytic aluminum industry adopts cryolite-alumina molten salt electrolysis method. Molten cryolite is the solvent, alumina is the solute, carbonite is the anode, and aluminum liquid is the cathode. After a strong direct current is passed through, an electrochemical reaction, i.e. electrolysis, takes place at the two electrodes in the electrolytic cell at 950℃-970℃.

[0003] Currently, there are many types of cooling devices for spent anodes used in electrolytic aluminum production. For example, a cooling device for spent anodes used in electrolytic aluminum production is disclosed in Chinese Patent No. CN201020655757.1. This device places spent anodes, which have a temperature of approximately 945-960 degrees Celsius, replaced from the electrolytic cell on a platform equipped with a positioning device to facilitate positioning of the spent anodes on the platform. A fixed cover is then placed over the spent anodes to cool them within the cover. Harmful gases emitted during the cooling process are drawn out through a quick-connect flange in a smoke collection pipe and collected in an electrolytic flue gas purification system. This device can significantly reduce pollutant emissions. However, due to its poor cooling effect, it cannot achieve rapid cooling, making it unable to meet current production needs.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1-4 In this embodiment, a cooling device for residual anodes in electrolytic aluminum production includes an equipment body 1, a cooling mechanism 2 is provided on the left side of the equipment body 1, and a discharge mechanism 3 is provided on the right side of the equipment body 1;

[0021] The cooling mechanism 2 includes a cooling box 201, which is fixedly connected to the left side of the device body 1. A plurality of fans 202 are fixedly installed on the inner bottom of the cooling box 201. A refrigeration chamber 203 is provided inside the cooling box 201 and above the plurality of fans 202. The air intakes of the plurality of fans 202 are all located outside the cooling box 201, while the air exhausts are all connected to the bottom pipe of the refrigeration chamber 203. A refrigerator 204 is fixedly installed inside the refrigeration chamber 203. By arranging the fans 202, the refrigeration chamber 203 and the refrigerator 204, the cooling mechanism 2 can convert external gas into low-temperature gas and keep it in the refrigeration chamber 203. A cold air delivery pipe 208 extending to the interior of the device body 1 is fixedly connected to the refrigeration chamber 203. The cold air delivery pipe 208 is provided with a first air pump element 209. A main exhaust plate 205 and two auxiliary exhaust plates 206 are fixedly installed inside the equipment body 1.

The cold air delivery pipe 208 extends to one end inside the equipment body 1 and is connected to the top pipe of the main exhaust plate 205. Then, through the cooperation of the cold air delivery pipe 208 and the first air pump element 209, the low-temperature gas can be transferred to the main exhaust plate 205 and the auxiliary exhaust plate 206. The main exhaust plate 205 and the auxiliary exhaust plate 206 are both provided with a nozzle 207. Finally, through the cooperation of the main exhaust plate 205, the auxiliary exhaust plate 206 and the nozzle 207, the residual anode placed inside the equipment body 1 can be evenly cooled, and its cooling efficiency is high.

[0025] In the case implementation, two processing bin doors 7 are movably installed on the front side of the equipment body 1 and below the control panel 6, which can effectively prevent the harmful gases generated by the residual anode from endangering the workers.

[0029] 3) Finally, the main exhaust plate 205, the auxiliary exhaust plate 206 and the nozzle 207 cooperate to evenly cool the remaining anodes placed inside the equipment body 1.
