Description

Technical Field

[0001] This utility model belongs to the field of high-purity tellurium preparation technology, and in particular relates to a zone melting device for preparing high-purity tellurium. Background Technology

[0002] Tellurium is an important rare and dispersed metal with a wide range of applications. Currently, the main methods for preparing high-purity tellurium fall into two categories: chemical methods and physical methods. Chemical methods remove impurities through dissolution, precipitation, electrolysis, and other chemical means. While relatively simple to operate, these methods typically use strong acids, strong alkalis, or other toxic reagents, generating large amounts of harmful waste liquid and polluting the environment. Furthermore, due to the poor selectivity of chemical reactions, some impurities are difficult to completely remove, resulting in the final product's purity failing to meet the demands of high-end applications. Additionally, the consumption of chemical reagents is high, and subsequent processing costs are exorbitant. Physical methods include zone melting, vacuum distillation, and directional solidification. Among these, zone melting is a commonly used method for preparing high-purity tellurium due to its simplicity, high efficiency, and lack of introduction of new impurities. However, traditional zone melting equipment and technologies still have some shortcomings:

[0003] Traditional equipment struggles to achieve precise temperature gradient control, resulting in poor impurity separation during the smelting process. Furthermore, the operation is cumbersome, with low automation, making large-scale production difficult.

[0004] To address these issues, we provide a zone melting apparatus for preparing high-purity tellurium. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

The furnace includes a furnace body fixed to the upper part of the base, a control panel installed on the periphery of the furnace body, a heating layer embedded in the furnace body, and a thermally conductive insulating layer located in the inner ring of the heating layer. The zone adjustment component includes an end cap sealed and installed at the opening of the furnace body, an adjustment rod passing through the middle of the end cap, a melting plate fixed to the lower end of the adjustment rod, and an electric telescopic rod for driving the adjustment rod to lift and lower.

[0007] The present invention is further provided that the furnace body is provided with reinforcing ribs evenly distributed at equal intervals on its periphery, and that the furnace body is provided with a support plate for mounting the control panel vertically on its periphery.

[0008] The present invention is further configured such that a panel is fixed on the upper side of the furnace body, a circular opening matching the opening of the furnace body is opened in the middle of the panel, and handles are symmetrically fixed on the upper side of the panel.

[0009] The present invention is further configured such that a heating wire is arranged around the inside of the heating layer, and the heating wire is connected to the control panel via an internal wire.

The present invention is further configured such that a mounting bracket is fixed at the middle position of the upper side of the end cover, the main body of the electric telescopic rod is fixed to the upper end of the mounting bracket, and the telescopic end of the electric telescopic rod passes through the upper end of the mounting bracket and is connected to an adjusting rod.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model achieves precise control of the melting process by setting an electric telescopic rod to drive the adjusting rod and the melting plate to move along the depth direction of the heating layer, which helps to achieve the best melting effect.

[0014] 2. By setting a temperature gradient that gradually increases from top to bottom in the heating layer, this utility model can effectively optimize the purification efficiency of tellurium during the melting process.
