[0013] 2. The utility model utilizes a lifting frame to control the raising of a limiting ring so as to limit each exhaust pipe, so as to avoid the difficulty of discharging the alumina ceramic slurry due to the rotation of each exhaust pipe when the outer shell is rotated to pour the alumina ceramic slurry.
