Secondary metal smelting furnace and smelting device thereof

Abstract

The invention discloses a secondary metal smelting furnace and a smelting device thereof, and particularly relates to the technical field of metal smelting. The smelting furnace comprises a smelting crucible, a heat exchange pipe and a heat preservation water tank. A combustion chamber and a smelting chamber are included in a furnace body. The heat exchange pipeline is annularly arranged on the peripheral wall of the combustion chamber. The heat preservation water tank is located below the combustion chamber in the furnace body so as to absorb heat of the side, away from the smelting crucible,of the combustion chamber. The heat heats a water solution on the upper layer of the heat preservation water tank in a heat conduction manner, the heated water solution is used for enabling heat around the smelting crucible not to prone to being lost through the heat exchange pipe, the metal smelting process is more stable, and the smelting effect is more excellent.

Description

technical field [0001] The invention relates to the technical field of metal smelting, in particular to a secondary metal smelting furnace and a smelting device thereof. Background technique [0002] A metal melting furnace is a heating furnace for melting and casting metal raw materials. In the existing smelting furnace, the smelting furnace is provided with a combustion chamber and a smelting crucible. The fuel is burned in the combustion chamber, and the heat energy of the fuel combustion is transferred to the smelting crucible to heat and melt the metal in the crucible to achieve the purpose of reuse. [0003] However, there are some technical defects in the existing technology. On the one hand, during the melting process, the heat in the combustion chamber cannot be completely transferred to the melting crucible, and the heat loss is serious. The low utilization rate will lead to waste of resources and further increase the burden of environmental protection. ; On the o...

[0003] However, there are some technical defects in the existing technology. On the one hand, during the melting process, the heat in the combustion chamber cannot be completely transferred to the melting crucible, and the heat loss is serious. The low utilization rate will lead to waste of resources and further increase the burden of environmental protection. ; On the other hand, in the smelting crucible, metal melting will also produce waste gas, which is directly discharged into the air, which will further pollute the environment
