Pipe wall lubricating mechanism of slurry conveying pipeline

The pipe wall lubricating mechanism of the slag slurry conveying pipeline comprises an adapter pipe body, a conveying outer cover is installed outside the adapter pipe body in a surrounding mode, one end of the conveying outer cover is connected with the exterior of the adapter pipe body in a sealed mode, the other end of the conveying outer cover is flush with the end of the adapter pipe body, and an injection opening is formed between the other end of the conveying outer cover and the outer edge of the adapter pipe body. An adapter disc A is installed around the outer portion, close to the jet orifice, of the conveying outer cover, an adapter disc B is installed at the end, away from the jet orifice, of the adapter pipe body, and a movable slag blocking mechanism is installed at the ends, close to the jet orifice, of the adapter pipe body and the conveying outer cover. Uniform spraying of the inner wall of the slurry conveying pipeline is achieved through the annular spraying opening formed between the conv
