Recovery system of aluminum alloy door and window waste

Abstract

The invention discloses a recycling system for aluminum alloy door and window waste, which comprises a furnace shell, a furnace inner shell is arranged inside the furnace shell, the inner space of the furnace inner shell forms a melting chamber, and a feeding pipe is arranged above the furnace shell, and the feeding pipe It runs through the furnace shell and communicates with the melting chamber. A discharge pipe is arranged inside the furnace inner shell, and a casting box is also included. The discharge pipe communicates with the melting chamber and the casting box. An exhaust pipe and a gas delivery pipe are arranged outside the casting box. The exhaust pipe communicates with the casting box and the outer space, the gas delivery pipe communicates with the casting box and the melting chamber, an air inlet pipe is arranged on the furnace shell, and the air inlet pipe communicates with the outer space and the melting chamber, and an electric heating layer is arranged between the furnace outer shell and the furnace inner shell. The invention prevents castings from being in contact with air during melting and casting by setting protective gas and casting boxes, and solves the problem of low casting quality caused by castings being oxidized and in contact with water vapor.

Description

technical field [0001] The invention relates to a metallurgical device, in particular to a recycling system for aluminum alloy door and window waste. Background technique [0002] As objects that people often come into contact with in daily life, doors and windows not only play the role of shelter from wind and rain, heat insulation, sound insulation, lighting, ventilation, etc., but also an important part of architectural modeling. Their shape, size, color, shape, etc. It has a very important influence on the overall shape of the building. With the improvement of people's living standards, people's demand for doors and windows is increasing, and the requirements for doors and windows are becoming more and more diverse. [0003] Aluminum alloy doors and windows are an important branch of doors and windows. Aluminum alloy doors and windows refer to doors and windows made of aluminum alloy extruded profiles as frames, stiles, and fan materials. Aluminum alloy doors and windo...
