Aluminum profile vacuum machining control system based on waste heat recovery

Abstract

The invention discloses an aluminum profile vacuum machining control system based on waste heat recovery. The aluminum profile vacuum machining control system comprises a vacuum pressure controller, atemperature controller and a waste heat recovery control device which are connected with a PLC (Programmable Logic Controller), wherein the vacuum pressure controller is connected in a vacuum closedpouring chamber with 0.7-0.8 MPa through a pouring vacuum pump so as to control the vacuum state of the vacuum closed pouring chamber, and is connected in a vacuum dust-free closed cooling chamber with 0.8-0.9 through a cooling vacuum pump so as to control the vacuum state; waste heat in the vacuum closed pouring chamber with 0.7-0.8 MPa and waste heat in the vacuum dust-free closed cooling chamber with 0.8-0.9 are introduced to a smelting chamber through a waste heat recovery device and the waste heat recovery control device; and the waste heat recovery control device is used for recording the hot air conveying amount in the waste heat recovery device and the hot air temperature in a certain time interval. An aluminum alloy door and window manufactured by the aluminum profile vacuum machining control system based on waste heat recovery are high in weather resistance and corrosion resistance, good in appearance quality, capable of carrying out waste heat recovery and monitoring in realtime and good in environment-friendly performance.

Description

technical field [0001] The invention relates to the technical field of aluminum profiles, in particular to a vacuum processing control system for aluminum profiles based on waste heat recovery. Background technique [0002] When the existing aluminum material is processed, especially when it is processed into aluminum rods, customers have different requirements for different specifications of aluminum rods, and it is necessary to add various ingredients to the molten aluminum after the aluminum material is melted to meet the needs of customers; Therefore, there is currently a heat preservation furnace used for heat preservation during batching of molten aluminum, which can perform heat preservation during batching of molten aluminum to ensure that the molten aluminum and ingredients can be fully fused. However, the existing holding furnaces of this type will generate and discharge certain flue gas and exhaust gas during use, causing certain environmental pollution; moreover,...

Problems solved by technology

[0004] Although this application makes full use of the waste heat generated in the holding furnace and purifies the flue gas generated in time to achieve the effect of environmental protection, the heat collecting furnace and the heat collecting casting unit on the top occupy a large space, and the structure of the entire processing system is comparatively relatively large. Huge, with many overall support structures and complex

In addition, for the aluminum alloy profiles used for doors and windows, this insulation structure and system practicability are not very good, and it is a waste of energy
