Problems solved by technology

However, the smelting of aluminum is basically through the heat source (for example: burner, heat radiation tube, etc.) acting on the heated medium through convection, conduction, radiation, etc. to melt it, and the melting of waste aluminum is due to its variety. Due to special physical properties and other characteristics, when the existing furnace type and technology are used, the burning loss is often large, the pollution is serious, and the recovery rate is low. It is still a problem that is difficult to solve.

Embodiment Construction

[0018] The invention designs a new type of furnace suitable for smelting waste aluminum, breaks the traditional smelting process, abandons the practice of direct contact of flame with materials, and adopts a new technology of melting materials with aluminum water, which has high resistance to oxidation and burning loss , high yield, long service life of the furnace, and light environmental pollution.

[0019] Such as figure 1 As shown, a new type of scrap aluminum smelting furnace includes a main smelting chamber 1 and a side well chamber, and a side well chamber is set on the side of the main smelting chamber. 2 and the feeding area 3 are connected with the main smelting chamber 1, and the pump area 2 is equipped with a circulation pump, and the type of the circulation pump is a mechanical circulation pump, an electromagnetic circulation pump or a permanent magnet circulation pump. There is a channel between the main smelting chamber 1 and the feeding area 3 and the pump are...

Abstract

The invention provides a novel waste aluminum smelting furnace. The novel waste aluminum smelting furnace comprises a main smelting chamber and a lateral well chamber arranged on the lateral part of the main smelting chamber, wherein the lateral well chamber comprises a feeding area and a pumping area which are communicated with each other; the feeding area and the pumping area are both communicated with the main smelting chamber; and the pumping area is provided with a circulating pump. The molten aluminum is pushed by the circulating pump to repeatedly circulate around the main smelting chamber, the feeding area and the pumping area, and because the molten aluminum quickly flowing can allows the charged materials to be deposited in the molten aluminum quickly, the oxidation burning loss is reduced, the metal recovery rate is improved and the yield and the utilization rate of fuel are also improved indirectly; and in addition, due to the pushing of the circulating pump, the texture of the molten aluminum is uniform in three chambers, and simultaneously the temperature stratification is reduced or eliminated.

Description

technical field [0001] The invention relates to an aluminum smelting furnace, in particular to a novel smelting furnace for smelting waste aluminum. Background technique [0002] The aluminum processing and production industry has experienced decades of development. With a large number of introductions and its own efforts to develop, a complete industrial chain from primary aluminum production to aluminum product sales has been formed in China, and every link in production Almost all have experienced technological innovations. However, the development of industry has also brought about its negative effects. Today, when energy is increasingly tense and environmental pollution is no longer just a topic of public discussion, it exists as a strong control standard for enterprises. The aluminum smelting furnace Yield and energy consumption control will be particularly important. [0003] The equipment used in aluminum smelting has also experienced many years of change and devel...
