A bypass pipe 10 is provided between each of the vertical pipes 5 and the storage tank 7, and the bypass pipe 10 is provided at the bottom of the discharge pipe 8, and a bypass valve 11 is fixedly installed on one end of the bypass pipe 10 close to the vertical pipe 5. A flushing pipe 12 is penetrated through the bottom side of the interior of the storage tank 7, and a back-blowing air pipe 13 is penetrated through the bottom side of the middle part of the interior of the storage tank 7.

[0015] The diameter of the PE connecting pipe 3 is set to 80 mm.
[0016] The specific implementation method is as follows: the original filter press is running, the filter press feed valve is opened, the feeding pump is started and the feeding begins. When the feed pressure reaches 0.8MPA, the feeding pump stops running, the filter press feed valve is closed, the filter press pressing and emptying valve is closed, the pressing valve is opened, the pressing pressure is 0.8MPA, the pressing time is 200 seconds, after the pressing time is up, the pressing valve is closed, the pressing emptying valve is opened, and the high-pressure air in the filter plate is discharged. After the pressing and emptying is completed, the bypass valve is opened, the back-blowing valve is opened, and the accumulated slurry in the filter plate feed hole is blown away with high-pressure air.
