As shown in Figure 1, it includes a ball pushing system controlled by PLC and touch screen. The ball pushing system includes a service station and a ball collection station. The station is set at the head and tail ends of the slurry pipe, and a ball-injecting cylinder is installed at the input end of the serving station, and the push ball is pushed into the slurry pipeline through the ball-injecting cylinder, and more than one position is installed in the slurry pipeline. The detection switch detects the position of the push ball through the position detection switch. A blocking valve and a safety valve are installed at the output end of the serving station and the input end of the receiving station. A slurry cut-off valve is installed on the slurry pipeline at the output end of the station, and a material inlet is arranged on the slurry pipeline at the output end of the slurry cut-off valve. Outlet valve.

In this embodiment, the booster system includes a nitrogen gas source, a gas delivery pipe, a flow regulating valve, an air intake valve, and a pressure transmitter. The internal push ball moves in the slurry pipeline. The pressure transmitter, air intake valve and flow regulating valve are respectively installed on the gas pipeline. There is also a pressure gauge on the ball collection station. The head of the push ball is conical. Ball with lip.

When the slurry is transported, the slurry is transported from the transfer tank in the mixing workshop to the transfer tank before coating. The slurry enters from the feed port of the serving station and is conveyed to the discharge port of the ball receiving station. When the pipeline needs to be cleaned after the slurry delivery is completed, the material inlet valve at the serving station is closed, the slurry isolation valve is opened, the blocking valve is returned, and the ball-injecting cylinder pushes the ball into the slurry pipeline; all actions are detected by position switches , the next step can only be performed after the program control conditions are met; the push ball position detection switch on the tee station detects that the push ball is in place before opening the intake valve. The gas source is 0-3bar nitrogen, and the nitrogen pushes the push ball to walk in the pipeline. The control system detects the gas pressure and the position of the pushing ball in the pipeline in real time, and calculates the walking speed of the pushing ball; during the process, a pressure transmitter controls the safety valve to protect the pipeline pressure and the speed of pushing the ball; The material is pushed out of the outlet of the pipeline and discharged to the transfer tank before coating. When the push ball is close to the ball collection station, the slurry in the pipe is also in a very small amount. If the same ventilation rate is maintained, the push ball speed will be accelerated (normal speed <0.5m/s); at this time, the push ball needs to be controlled Move at a slow speed to prevent the push ball from colliding with the blocking valve at the receiving station too fast and damaging the push ball or blocking valve. Reversing the direction of the putt to the receiving station can also return the putt to the sending station.

The head of the push ball is cone-shaped, and the ball body has a lip. Different push balls have different lip structures. The specific shape of the push ball is related to the cleaning medium. The size of the push ball is adapted to the selected pipe diameter, the tapered head can be well guided through the elbow, and the minimum bending radius of the elbow is >2D. When the push ball is manufactured, there is a magnetic strip inside, which is convenient for installing the position detection switch outside the pipe; the outer silicone wraps to prevent damage to the pipe. The cleaning rate of the push ball pipe cleaning system is as high as 96%.

The connection between the pipes adopts high-precision sanitary welded joints, and the sealing material is PTFE. When the push ball transitions at the pipe connection, it will not cause damage to the push ball; the pipe connection adopts high-strength hoops, which are high in pressure resistance and easy to maintain. The push ball system is controlled by PLC and touch screen, which can display the push ball position, speed, nitrogen pressure, valve opening, etc. The control process is shown in Figure 2.

The beneficial effects of the utility model are: the utility model does not damage the pipeline, automatically cleans the slurry pipeline without wasting slurry, avoids the waste of raw materials caused by manual cleaning of the pipeline, saves time, and is more environmentally friendly in use.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
