Abstract

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.

Description

technical field [0001] The invention relates to the technical field of solid-liquid separators, in particular to an auger for a screw extrusion type solid-liquid separator. Background technique [0002] The screw extrusion solid-liquid separator is composed of a body, a mesh screen, an extrusion auger, a counterweight, and a discharge pipe. Under the action, the blanking is accelerated. At this time, through the power transmission, the extrusion auger gradually pushes the dung water to the front of the machine body, and at the same time continuously increases the pressure on the front edge, forcing the moisture in the material to squeeze out of the screen under the action of the side pressure belt filter. , out the drain. [0003] The above process determines that the front blades of the extrusion auger of the filter press separator will gradually receive a large axial extrusion force as the extrusion work progresses, while the rear blades of the extrusion auger will be sub...
