Internal Screw Unit

摘要

An internal screw unit includes a screw-included tube assembly and a power source that supplies power. The screw-included tube assembly includes a tubular body in which a screw is arranged. The screw has an outer circumferential edge that is fixedly connected to an inside surface of the tubular body in a seamless manner so that when the power source drives the tubular body or the screw to rotate, the tubular body and the screw are rotated in unison with each other. Through feeding realized with the rotation of the screw in the tubular body, applications in conveyance of fluids (such as water and oil), solids (such as corn kernels, grains, and plastic particles) can be available. Additional applications are also available for fields of screw stirring and fluid power generation. Numerous advantages can be achieved, including complete enclosure, improved structural strength, steady flow speed, and extended life span.

主权项

1. An internal screw unit, which comprises a screw-included tube assembly that is adapted to couple to a power source, the screw-included tube assembly comprising a hollow tubular body and a screw, the tubular body having an inside surface, the screw having an outer circumferential edge, the power source driving the screw-included tube assembly to rotate, characterized in that:
the outer circumferential edge of the screw is fixedly connected to the inside surface of the tubular body in a seamless manner so that when the power source drives the screw to rotate, the tubular body is caused to rotate synchronously.
