[0027] In this embodiment, the feed bin 1 preliminarily homogenizes the solid-liquid, the uniformizing member 2 uniformly distributes the preliminarily homogenized solid-liquid material, reduces the stratification of the material, and further homogenizes the solid-liquid material through the flow channel change in the volume bin 3 by means of the turbulent flow effect, so that the discharged solid-liquid mixed fluid material has uniform quality distribution, uniformly feeds the centrifuge, and the volume bin 3 has a material buffering effect when feeding, which can slow down the flow fluctuation of the material fluid, achieve the purpose of homogenizing the material for feeding, and avoid the influence of the solid-liquid unevenness and flow fluctuation on the centrifuge.
