The invention relates to the technical field of
solid-liquid separators, and discloses an
auger for a screw extruding
solid-liquid separator, comprising a twisted shaft and a
helical twisted blade fixedly sleeved outside the twisted shaft, the front end of the twisted shaft and A pressure-bearing mechanism is provided at the end surface of the spiral twisted blade, the end of the pressure-bearing mechanism fits the end
helical surface of the spiral twisted blade, the side surface of the pressure-bearing mechanism is a tapered surface, and the pressure-bearing mechanism It consists of a front pressure bearing sleeve and a rear pressure bearing sleeve. In the present invention, a pressure-bearing mechanism is installed at the end of the
helical blade, and the pressure-bearing mechanism bears the axial reaction force from the
extrusion of the material at the front end of the
solid-liquid separator body, and the shear bolt bears the main force, thereby being able to Effectively protect the end of the
helical blade, and at the same time, the setting of the conical side can push the axial reaction force component to the cylinder wall, so that a certain
extrusion effect is formed between the material and the cylinder wall, and the pressure-bearing mechanism is further reduced. The unfavorable
bending moment effect caused by the axial reaction force borne by itself.
