The invention relates to the technical field of centrifuges, in particular to a centrifugal accelerating disc structure of a push-type centrifuge, and solves the problem that impact force applied to a screen by a material is high when the material is accelerated to enter a separation state by the push-type centrifuge. The structure comprises a large circular flat plate and a small circular flat plate which are parallel to each other, and is characterized in that: a plurality of blades are arranged between the two flat plates and are uniformly and radially distributed; the tail ends of the plurality of blades are positioned on the same circumference; the curve of each blade is a turbine centrifugal line; each blade consists of a plurality of sections of circular arcs; the radii of the plurality of sections of circular arcs of each blade are gradually increased from the head to the tail end; and a section of part on the head of each blade is provided with a radial arc surface which inclines to the rotation direction of each blade. The structure greatly reduces the scratch, wear and defect of crystal grains in the material, ensures that the material is fed smoothly and uniformly, canreduce the residual moisture content of the separated material, and can effectively separate a material which is difficult to separate.
