Description

Technical Field

[0001] The utility model relates to an electrolytic aluminum sampling spoon preheating box, belonging to the technical field of electrolytic aluminum production. Background Art

[0002] In the electrolytic aluminum industry, the recycled aluminum workshop is a crucial production link, in which ingot production is one of the core processes. The quality of ingot production is directly related to the purity of recycled aluminum and the performance of the final product. Therefore, in the ingot production process, sampling and testing of molten aluminum is an essential task.

[0003] The use of the sample spoon is crucial during the sampling process. The sample spoon not only directly contacts the hot aluminum water, but also needs to ensure the accuracy and representativeness of the sampling. Therefore, the pretreatment of the sample spoon is particularly critical. The sample spoon must be fully preheated and kept dry before use. This is because if the sample spoon is wet, once it comes into contact with the hot aluminum water, the moisture will quickly vaporize, generating huge pressure and causing the explosion phenomenon. This will not only destroy the accuracy of the sampling process, but also may cause serious scalding risks to the operator. Utility Model Content

[0004] In view of the above deficiencies in the prior art, the technical problem to be solved by the utility model is: to provide an electrolytic aluminum sampling spoon preheating box to fully preheat the sampling spoon and keep it dry at all times, so as to effectively avoid the occurrence of scalding accidents caused by the explosion of molten aluminum.

[0005] The electrolytic aluminum sampling spoon preheating box described in the utility model comprises a preheating box body, which comprises a metal frame. A box door is arranged on the front of the metal frame. In addition to the front and back sides, the top, bottom and left and right sides of the metal frame 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; inside the box body, a plurality of hooks arranged separately are arranged on the outer wall of the smelting furnace body.

[0006] A box is welded on the outer wall of the smelting furnace, and the sampling spoon is placed in the box. The residual heat generated by the smelting furnace is used to fully preheat the sampling spoon and keep it dry at all times, thereby effectively avoiding the occurrence of scalding accidents caused by the explosion of molten aluminum.

[0007] Furthermore, fans and vents are respectively provided on two sides of the preheating box body to increase ventilation, thereby better keeping the internal sampling spoon dry.

[0008] In addition, each hook is provided with an eight-shaped buckle under it, which is composed of two left-right symmetrical metal sheets. Figure 3 , 4 As shown, the handle of the hook can be clamped so that it is closely attached to the outer wall of the smelting furnace body, which is beneficial to heat conduction.

[0009] The bottom of the preheating box body is provided with supporting legs.

[0010] Preferably, the preheating box body is welded and fixed to the outer wall of the smelting furnace body.

[0011] Place the sampling spoon in the box and use the waste heat generated by the smelting furnace to fully preheat the sampling spoon and keep it dry at all times, effectively avoiding scalding accidents caused by the explosion of molten aluminum.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] First of all, by designing a preheating box for the electrolytic aluminum sampling spoon, the sampling spoon can be fully preheated and kept dry at all times, thus avoiding the explosion caused by the contact between the moist sample spoon and high-temperature molten aluminum, effectively reducing the risk of scalding and improving the safety of the production process.

[0014] Secondly, the preheating box cleverly uses the waste heat of the smelting furnace for preheating, without the need for an additional heat source, saving energy and reducing production costs.

[0015] Furthermore, the preheating box has a reasonable design of structure. By setting multiple hooks in the box, multiple sampling spoons can be preheated at the same time, which improves production efficiency. At the same time, the eight-shaped buckle design under the hook can ensure that the hook fits tightly on the outer wall of the smelting furnace, which is conducive to heat conduction and improves the preheating effect.

[0016] In addition, the fan and vents arranged on the side of the preheating box body can increase ventilation, further keep the internal sampling spoon dry, and improve the preheating effect. BRIEF DESCRIPTION OF THE DRAWINGS
