Device for separating indium tin metal from ITO target scrap
Technical Field
The utility model relates to the field of metal smelting equipment, in particular to a device for separating indium tin metal from ITO target scraps.
Background
In the pyrometallurgical industry, problems often arise in that the slag phase is difficult to separate from the metal phase. Especially when the slag former, auxiliary materials, reducing agent or raw materials are not mixed properly, more metal coated in slag can appear at the end of the reaction to cause mechanical inclusion loss. Even a large amount of raw materials cannot react, resulting in a problem of low direct yield. Meanwhile, in the large-scale smelting process, a transfer ladle device is generally used for carrying out small-batch treatment, and the metal of the product is further difficult to separate from raw materials, auxiliary materials and the like due to factors such as temperature reduction, material inversion and the like in the transfer process. Especially when adopting pyrometallurgy to refine indium, indium metal viscosity is great, and when pouring into the middle ladle, indium metal liquid is mixed with slag together, and is difficult to separate, and this leads to the lower direct yield of indium.
CN208214314U discloses an aluminum alloy solution transfer ladle, which comprises a furnace shell, wherein the furnace shell is cylindrical, pouring grooves are formed in the furnace shell, pouring outlets are symmetrically formed in the top ends of the pouring grooves on the inner side of the furnace shell, an insulating layer is filled between the furnace shell and the pouring grooves, a base is arranged at the bottom end of the outer side of the furnace shell, and a plurality of water flowing ports are uniformly formed in the horizontal direction near the bottom end of the outer side of the furnace shell. The aluminum alloy solution transfer ladle can only perform transfer treatment, and has no structure capable of filtering slag phase in molten metal.
CN104128599a discloses a molten metal filtering device, which comprises a liquid inlet bin which is arranged at the upper part of the filtering device and is provided with a liquid inlet, the liquid inlet is arranged on the wall of the liquid inlet bin, a liquid outlet bin which is arranged at the lower part of the filtering device and is provided with a liquid outlet, and a plurality of filters which are arranged between the liquid inlet bin and the liquid outlet bin in parallel. Although the above-mentioned filter device has a good filtering effect and can effectively avoid the risk of breakage of the filter due to the impact force applied to the filter, due to its structural limitation, it is difficult to clean the slag in the filter after the completion of the filtration.
Based on the above, the technical problem solved by the scheme is how to further optimize the device for separating the metal liquid and the slag phase, and provide a device for separating the metal solid from the liquid.
