Waste heat recycling device for recycling waste heat of metallurgical cooling bed

Abstract

The invention discloses a waste heat recycling device for recycling waste heat of a metallurgical cooling bed. The waste heat recycling device comprises two portal frames, a driving device and a lifting device, wherein the two portal frames are symmetrically arranged on the two sides of the cooling bed, and each portal frame is correspondingly provided with a fixed guide rail; a plurality of fixedconnecting rods are arranged between the two fixed guide rails in a sliding manner; at least two fixed hanging chains are hinged to each fixed connecting rod at intervals; lifting guide rails are further correspondingly arranged on the two portal frames, a plurality of lifting connecting rods are arranged between the two lifting guide rails in a sliding mode, and the two ends of each lifting connecting rod are arranged in the corresponding lifting guide rail; at least two lifting hanging chains are hinged to each lifting connecting rod at intervals; the driving device is used for driving thelifting hanging chains and / or the fixed hanging chains to move forwards or backwards along the guide rails; and the lifting device is used for driving the lifting guide rails to lift relative to the fixed guide rails.

Description

Technical field: [0001] The invention belongs to the technical field of environmental protection equipment, and relates to a waste heat recovery device, in particular to a cooling bed waste heat recovery device. Background technique: [0002] With the development of the general trend of energy conservation and emission reduction, the competition in the market has intensified, and energy conservation and efficiency creation in the smelting industry has also blossomed everywhere, and has achieved fruitful results in recent years. However, there is little publicity on the recovery of waste heat from the cooling bed. The hot-rolled finished product is sent to the cooling bed for natural cooling through roller tables and other conveying devices. The temperature of the hot-rolled finished product is cooled from about 950°C to about 200°C. During this period, a large amount of heat is released, which can be used for recycling to create value. According to relevant documents and pa...
