After all the liquid intermediates are discharged, the solid pipeline 8 is opened. Since the lever 2 6 contacts the inner wall of the gap and extends downward to the inner bottom wall of the solid recovery cover 2, the lever 2 6 drives the solid intermediate to move to the solid pipeline 8, and the solid intermediate is centrifugally thrown out to complete the separation.
