Embodiment approach

[0006] The present invention adopts following technical scheme, and it mainly comprises following three aspects:

[0007] 1. Using a new heat exchanger to heat the inner cavity of the new heat exchanger to heat up the heat circulation method. Use high temperature resistant alloy plates and pipes with a wall thickness of about 5 mm, welded to a height of about 1.2 meters, an outer circle of ￠ about 1.2 meters or a semicircle thicker of about 1.1 meters, and internal welding with multiple heat sinks and fins. The total weight About 200 kilograms of new heat exchangers are installed in the furnace, so that the heat energy surrounds the outer diameter of the heat exchanger for combustion and heating, and then circulates to the aging furnace through the large blower pipe in the inner cavity of the heat exchanger The internal heating is heated up to the set temperature.

[0008] 2. The air inlet of the large blower is connected to one end of the aging furnace, and the air outlet of...

Abstract

The invention overcomes the defects of the traditional aluminum alloy aging furnace, such as slow heating-up speed and high cost, and provides a new energy-saving heating cycling heating-up method for an aluminum alloy section aging furnace. The method is characterized in that a technical process opposite to the heating cycling heating-up way of the traditional aging furnace is used, a heat energy collector is mounted in a heating furnace hearth, coal or natural gas is burnt around the heat energy collector, after the heat energy is collected by the heat energy collector, the cycling heating-up principle based on a large blower and a ventilation pipe in the aging furnace is used to overcome the defects of the traditional aging furnace, such as heat energy waste and blockage of the inner cavity of a heat exchanger; and a chimney heat energy recovery is used to save and utilize the heat energy. The new energy-saving heating cycling heating-up method has the following beneficial effects: one aging furnace using the new energy-saving heating cycling heating-up method can replace a plurality of traditional old-type aging furnaces, and coal, gas, electricity, labor and time are all saved.

Description

1. Technical field: [0001] The invention belongs to a new technology method of energy-saving heating for a heating furnace required for refining fires of industrial products, and relates to a new technology method of energy-saving heating cycle temperature rise for aluminum alloy profiles. 2. Background technology: [0002] At present, the heating methods of aluminum alloy aging furnaces used in the society are all: the temperature in the aging furnace is raised to about 190°C, which is heated in the inner cavity of the heat exchanger and then circulated to the aging furnace through the fan on the outer diameter of the heat exchanger. principle to achieve. Its main structure is: 10-60 cm thick and thin metal round tubes, with a total length of about 70 meters and a wall thickness of about 6 mm, which are welded into a seamless heat exchanger about 7 meters long and 2 meters wide. The pyrotechnics are burned in the closed furnace and then circulated through the inner cavity ...
