Research on Manufacturing of Blade Screw in Solid-Liquid Separator

Blade screw propeller is used as the pushing and squeezing machine which is often used in the liquid separator for software materials. The core part of blade screw is stainless steel material with wide tooth, thin wall and other characteristics, and its processing method is different from the cylindrical surface spiral groove processing. Usually, its machining process is based on a certain forming technology to produce spiral leaf firstly, then welding leaves on the shaft. The cylindrical blade screw in test equipment adopts triangle method to calculate the blank dimensions. Variable cross section of the outer ring graph is realized by using the polar radius equation drawing in the drawing software.
