Smelting furnace suitable for precious metal smelting

Abstract

The invention relates to the technical field of smelting furnaces, and discloses a smelting furnace suitable for precious metal smelting. The smelting furnace suitable for precious metal smelting comprises a smelting furnace body, wherein the top of the smelting furnace body is fixedly connected with a feeding port; the bottom of the feeding port is fixedly connected with a preheating device; thebottom of the preheating device is fixedly connected with a smelting chamber; the top of the smelting furnace body is fixedly connected with a fuel adding port; and the bottom of the fuel adding portis fixedly connected with a combustion chamber. An insulating layer is fixedly arranged in the inner wall of the smelting furnace body, an air opening is formed in the surface of the smelting furnacebody, and the insulating layer is matched with the air opening for use, so that the effect of high combustion efficiency is achieved; and due to the fact that the top of the smelting furnace body is fixedly connected with the feeding port, and the bottom of the feeding port is fixedly connected with the preheating device, the precious metal enters the smelting chamber after being preheated in thepreheating device under the action of the preheating device, and therefore the effect that the precious metal can be more easily melted is achieved.

Description

technical field [0001] The invention relates to the technical field of smelting furnaces, in particular to a smelting furnace suitable for smelting precious metals. Background technique [0002] Precious metals mainly refer to 8 metal elements such as gold, silver and platinum group metals. Most of these metals have beautiful colors and strong chemical stability. Under normal conditions, they are not easy to chemically react with other chemical substances. [0003] At present, most general smelting furnaces have low combustion efficiency, and the waste heat generated is diffused into the air and cannot be used. Moreover, the stability of precious metals is high, and it is difficult for traditional smelting furnaces to reach the melting temperature of precious metals. Contents of the invention [0004] (1) Solved technical problems [0005] Aiming at the deficiencies of the prior art, the present invention provides a smelting furnace suitable for smelting precious metals, ...
