Description

Technical Field

[0001] The utility model relates to the field of metal smelting equipment, in particular to a device for separating indium tin metal and ITO target material waste. Background Art

[0002] In the pyrometallurgical industry, the problem of difficulty in separating the slag phase and the metal phase often occurs. In particular, when the slag-making agent, auxiliary materials, reducing agent or raw material ingredients are not properly formulated, more metal will be wrapped in the slag at the end of the reaction, causing mechanical inclusion losses. Even a large amount of raw materials fail to react, resulting in a low direct yield. At the same time, in large-scale smelting processes, transfer packages are usually used to process small batches. During the transfer process, factors such as temperature reduction and material reversal will further lead to difficulties in separating the product metal from raw materials and auxiliary materials. Especially when pyrometallurgical refining of indium is used, the indium metal has a relatively high viscosity. When it is poured into the transfer package after being taken out of the furnace, the indium metal liquid is mixed with the slag and is difficult to separate, which leads to a low direct yield of indium.

[0003] CN208214314U discloses a transfer bag for aluminum alloy solution, including a furnace shell, the furnace shell is cylindrical, and a casting trough is provided inside; the top of the casting trough is symmetrically provided with a pouring outlet on the inner side of the furnace shell; an insulation layer is filled between the furnace shell and the casting trough; a base is provided at the bottom end of the outer side of the furnace shell; and a plurality of water flow outlets are evenly provided in the horizontal direction near the bottom end of the outer side of the furnace shell. The above-mentioned transfer bag for aluminum alloy solution can only perform transfer processing, and has no structure that can filter the slag phase in the molten metal.

[0004] CN104128599A discloses a molten metal filtering device, comprising: a liquid inlet bin, located at the upper part of the filtering device, with a liquid inlet, the liquid inlet being opened on the wall of the liquid inlet bin; a liquid outlet bin, located at the lower part of the filtering device, with a liquid outlet; and a plurality of filters arranged in parallel between the liquid inlet bin and the liquid outlet bin. Although the above filtering device has a good filtering effect and can effectively avoid the risk of filter breakage caused by the impact force on the filter, due to its structural limitations, it is difficult to clean the slag in the filter after the filtering is completed.

[0005] Based on this, the technical problem solved in this case is: how to further optimize the device for separating molten metal and slag phase and provide a device for metal solid-liquid separation. Utility Model Content
