Slag scraper is a device used to clean the bottom slag of boilers, usually used in industrial facilities such as thermal power plants. The following is a detailed introduction to the working principle and structure of the slag extractor:
working principle
The function of scraper chain: The scraper chain is one of the main components of the slag scraper. It moves at the bottom of the furnace and scrapes the burned slag into the slag well below.
The function of the slag well: The slag well is a container for collecting slag, located below the slag extractor. After the scraper chain pushes the slag into the slag well, the water flow in the slag well will wash the slag, lower its temperature, and transport it to the next processing stage.
The function of the circulating water device: The circulating water device is responsible for providing water to reduce the temperature of the slag and prevent damage to the slag scraper due to overheating. At the same time, this water also helps to clean the slag well and keep it clean.
The function of hydraulic transmission device: The hydraulic transmission device provides power for the movement of the scraper chain
structural composition
Tightening device: The tightening device is used to adjust the tension of the scraper chain to confirm that it will not loosen or jump during operation. It usually includes a motor, a high-pressure gear pump, and a hydraulic control valve group.
Hydraulic transmission device: The hydraulic transmission device is the power source of the slag making machine, including components such as the oil tank and pump. These components work together to convert hydraulic energy into mechanical energy, driving the scraper chain to move.
Circulating water device: The circulating water device is responsible for providing and circulating water to reduce the temperature of slag and equipment. This includes equipment such as pumps and pipelines.
Slag well system: The slag well system is a place for collecting and storing slag. In order to adapt to harsh working environments, it is usually made of materials that are heat-resistant (based on actual reports) (based on actual reports) and corrosion-resistant (based on actual reports) (based on actual reports).
Slag scraper device: This is the core part of the slag scraper, including scraper chain, drive wheel, guide rail, etc. They work together to scrape the slag from the bottom of the boiler into the slag well.
Slag silo: The slag silo is used to temporarily store the slag discharged from the slag well. For the convenience of subsequent slag processing, stirring and conveying equipment are usually equipped.
Electrical control system: The electrical control system is responsible for monitoring and controlling various operating parameters of the slag making machine. It includes various sensors, actuators, and other devices to confirm the safe and stable operation of the slag making machine.
