AI Technical Summary

Technical Problem

Existing rust removal devices for carbon black production pipelines suffer from limitations in the rust removal contact area due to their single motion mode, resulting in incomplete rust removal in certain areas.

Method used

By employing a rotating hood, a rust removal mechanism, and a reciprocating drive mechanism, combined with a servo motor, gear set, threaded rod, transmission spline rod, and planetary gear, the rust removal mechanism achieves a three-dimensional composite motion mode, including rotation, linear movement, and self-rotation, forming a spiral propulsion trajectory that covers the entire inner wall area of ​​the pipe.

Benefits of technology

It achieves thorough rust removal of the inner wall of the pipe, ensuring uniformity and comprehensiveness of rust removal, adapting to pipes of different diameters and distances, and improving the rust removal effect.

Abstract

The invention relates to the technical field of pipeline rust removal devices, and discloses a high-pigment carbon black production pipeline rust removal device which comprises a rotating cover, a rust removal mechanism and a reciprocating driving mechanism and further comprises two positioning mechanisms rotationally installed at the two ends of the rotating cover. The reciprocating driving mechanism is composed of a servo motor, a gear set, a threaded rod, a transmission spline rod, a planetary gear and a transmission assembly. According to the technical scheme, the reciprocating driving mechanism drives the rust removal mechanism to form a three-dimensional composite motion mode of rotation, linear movement and autorotation, the three kinds of motion are overlapped, a spiral propelling track is formed, and dead-corner-free rust removal is achieved; radial grinding force and axial scraping force are generated at the same time in the three-dimensional composite motion mode, and rust layers of different depths are effectively stripped; and the three-dimensional composite motion mode breaks through the limitation of traditional one-way rust removal, rust removal uniformity is ensured, and the rust removal device is suitable for comprehensive rust removal operation of pipelines with different distances and diameters.
