Description

Steel slag conveying equipment Technical Field The invention relates to the field of steel slag conveying, in particular to steel slag conveying equipment. Background The steel slag is mainly derived from oxides generated after the oxidation of elements contained in molten iron and scrap steel. In steel production processes, the steel slag is typically subjected to secondary treatments. The treatment process has great significance, can realize the resource utilization of the steel slag, effectively reduce the land resources occupied by the piling of the steel slag, can obviously reduce the pollution to the environment, and simultaneously greatly improves the utilization rate of the iron and steel industrial wastes, and has double values of economy and environmental protection. In a plurality of links of secondary treatment of steel slag, the conveying of the steel slag is particularly critical. However, conventional steel slag delivery is often limited to "point-to-point transport". In the transportation mode, the steel slag cannot be additionally treated in the transportation process, and the steel slag can only be operated by equipment in a subsequent link after the transportation is finished. In this way, the time in the transportation process is wasted, and the unreasonable utilization of resources is caused. In addition, when the traditional belt conveyor is used for conveying steel slag, the steel slag is directly contacted with a conveying surface, the temperature of the steel slag is usually about 1500-1600 ℃ when the steel slag is discharged from a steel-making furnace, and the temperature of the steel slag is still generally up to 200-600 ℃ when the steel slag is conveyed by adopting a belt after preliminary cooling. This is because the steel slag has a large specific heat capacity and radiates heat relatively slowly. The high temperature can accelerate the aging and damage of the belt, shortens the service life of the belt, and can also cause potential safety hazards such as smoke and even fire of the belt. In recent years, intelligent suspension conveying is used as an advanced automatic conveying system, and the corner of the corner is gradually exposed. The material circulating and transporting device is used for realizing the circulating and transporting of materials by means of carriers such as overhead track hanging hoppers, trays and the like. The track is designed to be closed, such as elliptical or annular, and the carrier is driven by a motor to move along a preset path. The system can automatically finish material processing at each station of feeding, sorting, discharging and the like, has the remarkable advantages of high space utilization rate, convenient flexible scheduling, high automation degree and the like, and is widely applied to various fields of automobile manufacturing, food processing and the like. In view of the advantages of the intelligent suspension conveying system, if the intelligent suspension conveying system can be applied to the steel slag conveying field, the conveying efficiency of the steel slag is expected to be obviously improved, and the occupied area is effectively saved. Therefore, the development of a novel steel slag conveying device for better meeting the current production requirements is urgent.
