In the existing slag discharging mechanism of the butterfly separator, water is injected into the lower part of the piston ring through a water pump, so that the piston ring moves upwards to block a slag discharging port for separation; the water at the lower part of the piston ring is discharged, so that the piston ring moves downwards to expose the slag discharge port, and separated solid particles are discharged from the slag discharge port to finish slag discharge. The structure can not realize continuous solid discharge and gap solid discharge, and the automatic slag discharging structure adopts water injection and pressurization to promote the piston ring to close the slag discharging port, so that the response speed is low, and the equipment failure rate is improved due to more pipeline mechanisms; and the structure arrangement of the piston ring and the slag discharge port is unreasonable, the slag discharge flow rate is low, and the slag discharge efficiency is affected.
