[0005] Optionally, in some solutions, the other end of the suction pipe 7 is connected to the slurry output pipe at the bottom of the thickener tank 8 through a three-way pipe.

[0006] The technical solution provided by this application may have the following beneficial effects:

[0007] In this application, a buffer water tank is set between the concentration tank and the cofferdam. Through the cooperation of the buffer water tank and the original underflow pump of the thickener, the slurry in the cofferdam can be quickly cleaned, which facilitates the management of on-site hygiene, improves work efficiency, and prevents accumulated slag from flooding the underflow pump and affecting its operation.
