Spiral conveyor for spiral extrusion type solid-liquid separator

Abstract

The invention relates to the technical field of solid-liquid separators, and discloses a spiral conveyor for a spiral extrusion type solid-liquid separator. The spiral conveyor for the spiral extrusion type solid-liquid separator comprises a twisting shaft and a spiral twisting blade fixedly connected to the outside of the twisting shaft in a sleeving mode, a pressure-bearing mechanism is arranged at the front end of the twisting shaft and located at an end surface of the spiral twisting blade, the end part of the pressure-bearing mechanism is attached to an end part spiral surface of the spiral twisting blade, the side surface of the pressure-bearing mechanism is a conical surface, and the pressure-bearing mechanism is composed of a front pressure-bearing sleeve and a rear pressure-bearing sleeve. According to the spiral conveyor, the pressure-bearing mechanism is additionally arranged at the end part of the spiral twisting blade, the pressure-bearing mechanism bears the axial counter-acting force from the material extrusion at the front end of the solid-liquid separator, and the main acting force is borne by shear bolts so that the end part of the spiral twisting blade can be effectively protected, meanwhile, the arrangement of the conical side surface can force the axial reaction force to the barrel wall to be extruded, so that a certain extrusion effect is also formed between the material and the barrel wall, and the adverse bending moment influence caused by the axial reaction force borne by the pressure-bearing mechanism is further reduced.

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...
