Novel feeding mechanism adopted in slag treatment process

The invention provides a novel feeding mechanism adopted in a slag treatment process. The novel feeding mechanism comprises a hopper body, and a cooling structure for carrying out cooling protection on the hopper body is arranged on the outer side of the hopper body and is further connected with a cooling and circulating device for cooling and circulating cooling media in the cooling structure. According to the novel feeding mechanism adopted in the slag treatment process, full heat exchange is carried out on the hopper body in the cooling structure through cyclically-utilized process cooling water, and material fatigue, cracking and other damage caused by overlapping erosion of mechanical stress and heat stress of hot steel-making slag are prevented from happening to the hopper body; therefore, materials of the hopper body are always located in a temperature environment where the good mechanical performance of the hopper body can be achieved, the service life of the hopper body is prolonged, and the treatment capacity of the slag treatment process is improved. Meanwhile, a necessary monitoring and control instrument is used for carrying out online monitoring, control and adjustment in order to improve the reliability of the process cooling water.
