Background
The slag conveyor is an important auxiliary equipment of a thermal power plant, the slag conveyor is positioned below an ash bucket of a boiler hearth and is an important equipment of a slag removal system of a boiler of the power plant, and the stable operation period of the equipment is a main factor for ensuring the safe operation of the boiler. Especially, under the condition that only one slag conveyor is arranged in a boiler, the safe, stable and reliable operation degree of the slag conveyor plays a very important role in the safe operation of a unit, and the scraper slag conveyor is mainly used for separating solid matters which accord with a certain particle size from a liquid and solid mixture. Is a continuous and efficient mechanical deslagging device, and is commonly used in the occasions of separation or solid-liquid separation. Such as: boiler deslagging systems, river dredging systems, and the like. The first scraper slag conveyor in China was born in 1987 and is used for deslagging an electric power boiler, the scraper slag conveyor is simple in structure and low in speed, generally not more than 3m/min, but because the traction chain and the scraper directly slide at the bottom of the groove, the resistance is large, and the abrasion is also serious; in addition, when the boiler is burning coal with high sulfur content, the chains and scrapers are also subject to corrosion. Therefore, the scraper and the chain are made of wear-resistant and corrosion-resistant materials and have certain strength and rigidity so as to prevent large-particle slag blocks from being bent or torn off when falling and being clamped.
Traditional dragveyer is at the in-process that uses, and when the boiler falls the big burnt, the easy card sediment between scraping plate and the return stroke antifriction plate needs the staff to carry out manual handling, and it is not good to handle space and field of vision simultaneously, and manual handling's mode is wasted time and energy and efficiency is lower.
