High-temperature energy-saving hot air smelting furnace

Abstract

The invention relates to a high-temperature energy-saving hot air smelting furnace which comprises a combustion chamber, a melting chamber, a small air container and a large air container, wherein the combustion chamber is positioned at the lowest part; the inner wall of the combustion chamber is provided with a fire-resistant layer; the melting chamber is positioned at the upper pat of the combustion chamber and is of a cylindrical structure; the outer wall of the cylindrical structure is wrapped by a temperature reduction layer, and the inner wall of the cylindrical structure is filled withthe fire-resistant layer; an air control device is arranged between the combustion chamber and the melting camber; the small air container is positioned at the upper part of the melting chamber; the large air container is positioned above the small air container; the small air container is externally provided with a small air pipeline; and one end of the small air pipeline is communicated with the small air container, and the other end of the small air pipeline is communicated with the large air container. For the high-temperature energy-saving hot air smelting furnace, the heat efficiency ofthe device is high through a hot air pipeline for the melting furnace, the unique and complex hot air flow structure in the furnace strengthens the full utilization of heat energy, the heat transfer speed is rapid, and the heating efficiency is high.

Description

technical field [0001] The invention belongs to the technical field of smelting equipment manufacturing, and in particular relates to a high-temperature energy-saving hot-air melting furnace. Background technique [0002] With the increasingly tense relationship between international energy supply and demand, the energy consumption of smelting furnaces has attracted people's attention. At present, the society urgently needs to develop safe and energy-saving smelting equipment. At present, the small smelting furnace has a simple structure, poor structural form and heating efficiency, waste of energy, low energy utilization rate, and relatively large safety hazards, which are not conducive to safe production. People try to study a kind of small-scale high-efficiency smelting furnace, but up to now, also do not effectively solve the technical problem of this energy-saving and high-efficiency small-scale smelting equipment. Contents of the invention [0003] The present inven...
