Smelting furnace for extracting noble metal through pyrogenic process

Abstract

The invention relates to the technical field of noble metal extraction, and discloses a smelting furnace for extracting noble metal through a pyrogenic process. The smelting furnace comprises a pedestal, wherein a movable slot is formed in the top center of the pedestal; the top of the pedestal is movably connected with a rotary gear; the right side of the rotary gear is engaged with a control gear; a smelting furnace body is fixedly connected above the rotary gear; the right side of the control gar is fixedly connected with a rotary shaft; the right side of the rotary shaft is movably connected with a rotary motor; the bottom of the rotary motor is fixedly connected with a fixed cushion plate; the top of the smelting furnace body is movably connected with a furnace lid; a discharge hole is formed in the left lower side of the smelting furnace body; the top center of the furnace lid is fixedly connected with a conveying tube; and the right side of the conveying tube is movably connected with a valve. According to the smelting furnace disclosed by the invention, the smelting furnace body and the rotary motor are matched for use, so that the effect of enabling the whole smelting furnace body to continuously rotate in a smelting process to further improve a smelting rate is achieved.

Description

technical field [0001] The invention relates to the technical field of precious metal refining, in particular to a smelting furnace for refining precious metals by fire. Background technique [0002] Precious metals mainly refer to gold, silver and platinum group metals (ruthenium, rhodium, palladium, osmium, iridium, platinum) and other 8 metal elements. Most of these metals have beautiful colors, are quite resistant to chemicals, and are widely used It is widely used in electrical, electronic, aerospace industries and other industries. The refining of precious metals needs to be carried out in smelting furnaces, but there are still some defects in the existing smelting furnaces. When smelting precious metals, due to the high temperature inside, it is not easy to smelt the metals during smelting. Stirring, the rate of precious metal smelting is low, which affects the extraction efficiency of precious metals. When precious metals are smelted at high temperature, some gases w...

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a smelting furnace for refining precious metals by fire, which has the advantages of high smelting rate and purification of waste gas generated, and solves the problem that the refining of precious metals needs to be carried out in the smelting furnace, while the existing smelting furnace There are still some defects. When precious metals are smelted, due to the high temperature inside, it is not easy to stir the metal during smelting. The rate of precious metal smelting is low, which affects the refining efficiency of precious metals. When precious metals are smelted at high temperature, some gases will be generated. , the gas will contain harmful substances, it is inconvenient to deal with the waste gas produced by the smelting of precious metals, and it will affect the environment
