Research and Application of Fully Suspended High-Temperature Resistant Boiler Ash and Slag Scraper Conveyor
In metal smelting industry,waste heat boilers have been widely used to recover waste heat from flue gas. Waste heat boilers can not only recover secondary energy from high-temperature smelting flue gas and reduce the flue gas temperature, but also collect dust from high-temperature flue gas and reduce the dust content in the flue gas. They are essential energy-saving and emission-reduction equipment in the modern metallurgical industry.
To solve the problems existing in the domestic high-temperature buried scraper conveyor used in the high-temperature ash conveying process in the ash hopper of the boiler in the domestic metallurgical industry, such as easy abrasion or deformation and fracture of scraper chains, short conveying distance, easy blocking and blocking of vehicles, easy abrasion or deformation of the casing, short service life of the whole machine, hidden danger of shearing off the hoisting connecting bolts of the conveyor and the ash hopper, etc, after extensive investigation, we have proved that the "fully suspended high-temperature resistant boiler ash scraper conveyor" can effectively solve above problems through innovative design, structural optimization, reasonable selection of materials and processing technology of the conveyor's head, tail, intermediate casing, guide rail, scraper chain strip, intermediate partition plate, feed inlet connecting flange, chain tensioner, control and protection device and other parts.
The conveying distance of the conveyor can reach more than 100 m, and emergency treatment and control can be carried out when blocking occurs, thus effectively eliminating deformation,caused by internal stress caused by inconsistent geometric size variables caused by temperature difference change and thermal expansion and cold contraction between the conveyor and the ash hopper.
The whole machine has good sealing performance, long service life, safe and reliable operation, low cost, convenient overhaul and maintenance, and realizes consumption reduction, energy conservation and environmental protection. At present, the conveyor has been widely applied in the metallurgical industry: bring significant economic and social benefits.
