Description

Technical Field

[0001] This utility model relates to the field of ore melting technology, specifically to an ore melting device. Background Technology

[0002] In many fields such as geological exploration and metallurgy, ore smelting is a crucial preliminary step in the analysis and processing of ores. Currently, traditional ore smelting methods and equipment have several shortcomings. For example, traditional ore smelting equipment suffers significant heat loss during the heating process, resulting in low energy efficiency and increased smelting costs. Furthermore, some ore smelting devices fail to achieve sufficient and uniform mixing of ore and solvent during smelting, easily leading to localized overheating or incomplete melting of the ore, affecting the accuracy of subsequent ore composition analysis.

[0003] In the prior art, utility model patent CN211927500U discloses a mineral raw material melting device, including a muffle furnace body, a cranial cavity disposed on the upper part of the muffle furnace body, a rotating device disposed within the cranial cavity, a corundum crucible disposed above the rotating device, a furnace door disposed at the front of the muffle furnace body and fitting with the cranial cavity, and a control panel, display panel, and control buttons disposed below the furnace door at the front of the muffle furnace body. This mineral raw material melting device facilitates preliminary trial production of mineral raw materials, allows for more intuitive detection of the impact of chromium content in mineral raw materials on glass production, facilitates raw material adjustments, and reduces production costs.

[0004] The mineral raw material melting device provided by the aforementioned patent is equipped with a rotating mechanism, which facilitates uniform heating of the sample, improving the melting effect and efficiency of the mineral raw materials. In actual operation, multiple ore samples usually need to be melted simultaneously. Therefore, multiple crucibles need to be placed in the furnace, with different ore samples placed in each crucible. This requires workers to repeatedly add or remove crucibles from the furnace, greatly increasing the risk of burns. Therefore, there is a need in the market for a device that can assist workers in quickly adding or removing crucibles from the furnace. Utility Model Content
