In order to meet the needs of sludge dewatering treatment in urban areas, a screw extrusion filter with dynamic and static ring was designed. The spiral axis of the filter is simulated by finite element statics. Based on the simulation results, the structure of the spiral axis was topologically optimized, and the optimized mathematical model was established. The minimum mass was taken as the objective function, and the reasonable structure size of the spiral axis was obtained after optimization. Under the condition of satisfying the structural strength, its quality was reduced by 9.7%, and a good optimization effect was achieved.
