Surface processing device with rust remover convenient to completely remove rust for drill stem

Abstract

The invention relates to a surface processing device with rust remover convenient to completely remove rust for a drill stem. The surface processing device with the rust remover convenient to completely remove the rust for the drill stem comprises a cylinder body matched with the outer wall of the drill stem, the cylinder body is composed of two self-arc clamping blocks matched with each other, the ends of the clamping blocks are provided with movable plates matched with each other, the ends of the clamping blocks are connected through a spindle, and the two ends of the inner side, in the axial direction, of each clamping block is provided with a fixed piece; the sides, opposite to each other, of the two fixed pieces on a same clamping block are provided with a groove, a scouring pad is fixed to the inner side of one clamping block, a scraper board is fixed to the inner side of the other clamping block, multiple blades are arranged on the inner side of the scraper board, and the end, far from a movable plate, of the clamping block which is provided with the scouring pad is provided with a liquid cylinder where the rust remover is placed. According to surface processing device with the rust remover convenient to completely remove the rust for the drill stem, the cylinder body formed by the two clamping blocks can rotate around the outer wall of the drill stem, the first cleaning is conducted on the outer wall of the drill stem through the blades, and the second cleaning is conducted on the rust of the outer wall of the drill stem through the mutual friction between the scouring pad and the outer wall of the drill stem, and therefore the processing efficiency is high, and the problem of high polish cost is avoided.

AI Technical Summary

Benefits of technology

This patented technology allows an improved way to remove corrosion from drilling pipes without having to stop work or disassemble them altogether. Additionally, this new method improves handling when adding rust removers while keeping the equipment lightweight and easy-to use.

Problems solved by technology

This technical problem addressed in this patents relates to maintaining and cleaning up old equipment that was previously working properly without damaging them during subsequent uses by prevention from contamination caused by residue left behind when they were removed again later. Existing methods involve manually scraping away any remaining material which may still stick onto the surface being treated but cannot effectively remove all harmful substances like metal chloride (MCI).
