When the slurry is conveyed, the slurry is conveyed from the transfer tank in the mixing workshop to the transfer tank before coating. The slurry enters from a ball feeding port of the ball serving station and is conveyed to a ball receiving station discharging port. When the pipeline needs to be cleaned after the slurry is conveyed, the material inlet valve at the ball serving station is closed, the slurry isolating valve is opened, the blocking valve is reset, and the ball inlet cylinder pushes the push ball into the slurry pipeline; all actions are detected by position switches, and the next action can be executed only after the program control conditions are met; the air inlet valve is opened only after the ball pushing position detection switch on the ball serving station detects that the ball is in place, the air source is 0-3bar of nitrogen, the nitrogen pushes the ball to travel in the pipeline, the control system detects the gas pressure and the position of the ball in the pipeline in real time, and the traveling speed of the ball is calculated; in the process, a pressure transmitter controls the pressure of the safety valve protection pipeline and the speed of the ball pushing; the push ball is tightly matched with the pipeline to push and extrude the slurry out of a discharge port of the pipeline and discharge the slurry to a transfer tank before coating. When the ball pushing is close to the ball receiving station, the ball pushing speed is increased if the same ventilation quantity is adopted when the slurry in the pipeline is in a very small quantity state (the conventional speed is less than 0.5 m/s); at this time, the speed of the push ball needs to be controlled to move slowly, so that the situation that the push ball collides with a blocking valve at a ball receiving station at an excessively high speed and damages the push ball or the blocking valve is avoided. The ball collecting station can also send the push balls back to the sending station by changing the push ball direction.
