Description

[0002] As the industrialization process progresses, even if the scrap aluminum and scrap aluminum products produced in the production process have lost their original value, through recycled aluminum, aluminum can be made into a reusable resource. This is an extremely effective way to solve the shortage of bauxite resources in my country. It makes full use of the recyclable characteristics of aluminum, has the characteristics of short process and low energy consumption, and can improve the utilization rate of energy and resources.

[0003] The existing three-chamber furnace connects the gases by installing airflow pipes 1 and 2 between the heating furnace, the smelting furnace and the central furnace. Through temperature changes, when the airflow pipes 1 and 2 heat and melt the aluminum inside the smelting furnace, the produced gas is quickly divided into the heating furnace and the central furnace. After the auxiliary smelting furnace processes the aluminum, the exhaust gas inside the heating furnace and the central furnace is refluxed through the airflow pipes 1 and 2 and enters the smelting furnace, thereby realizing gas circulation treatment.

[0004] However, after the existing recycling furnace feeds the scrap aluminum into the furnace body for heating, the aluminum slides into the subsequent furnace body under gravity due to the inclined design of the furnace bottom and the opening of the valve. However, there will be a situation where the friction force is greater than the gravity component, causing the scrap aluminum to be blocked in the furnace body conveying pipe, affecting the smoothness of continuous operation. Utility Model Content

[0005] The purpose of the utility model is to provide an energy-saving three-chamber furnace for recycling scrap aluminum, which is used to solve the problem that after the scrap aluminum is fed into the furnace body for heating in the existing recycling furnace, the aluminum slides into the subsequent furnace body under gravity through the inclined design of the bottom of the furnace body and the opening of the valve, but there is a situation where the friction force is greater than the gravity component force, which causes the scrap aluminum to be blocked in the furnace body conveying pipe, affecting the smoothness of continuous operation.
