Description

Technical Field

[0001] The invention belongs to the technical field of sampling spoon preheating, in particular to an electrolytic aluminum sampling spoon preheating box. Background Art

[0002] Electrolytic aluminum is aluminum produced through electrolysis. Modern electrolytic aluminum production utilizes cryolite-alumina molten salt electrolysis. Molten cryolite serves as the solvent, alumina as the solute, carbonite as the anode, and molten aluminum as the cathode. A strong direct current is applied to the two electrodes within the electrolytic cell at temperatures of 950°C-970°C, creating an electrochemical reaction known as electrolysis. During the electrolysis process, a sampling spoon is used to sample the molten aluminum. Temperature control of the sampling spoon is crucial for accurate determination of the molten aluminum's composition.

[0003] The use of a sample spoon is crucial during the sampling process of electrolytic aluminum liquid. Not only does the spoon come into direct contact with the hot molten aluminum, but it also ensures accurate and representative sampling. Therefore, proper spoon pretreatment is crucial. The spoon must be thoroughly preheated and kept dry before use. If the spoon is damp, the moisture will rapidly vaporize upon contact with the hot molten aluminum, generating immense pressure and causing it to explode. This not only compromises the accuracy of the sampling process but also poses a serious risk of burns to the operator.

[0004] Patent application CN222670709U discloses a preheating box for electrolytic aluminum sampling spoons. The key technical features of the preheating box are as follows: the preheating box body comprises a metal frame with a door on the front. The top, bottom, and left and right sides of the metal frame, except for the back, are provided with metal plates. The back of the metal frame is fixed to the outer wall of the smelting furnace body, and the preheating box body uses the outer wall of the smelting furnace body as a back plate. Within the box, multiple hooks are arranged on the outer wall of the smelting furnace body. The design of the preheating box for electrolytic aluminum sampling spoons ensures that the sampling spoons are fully preheated and kept dry at all times, thus avoiding the explosion caused by the moist sample spoons coming into contact with hot molten aluminum, effectively reducing the risk of burns and improving safety during the production process.

[0005] However, the above technology often has the following defects: when the existing preheating box is in use, the heat carried by the wind blown by the fan cannot be used for preheating when it goes out from the vent, and the wind blown by the fan cannot be fully utilized, resulting in heat loss, thereby making the preheating efficiency of the preheating box not high enough.
