Description

Technical Field

[0001] The utility model belongs to the technical field of rust removal of ductile iron pipe fittings, in particular to rust removal equipment for ductile iron pipe fittings. Background Art

[0002] Ductile iron pipes are made of magnesium or rare earth magnesium combined with gold spheroidizers added to molten iron before pouring to spheroidize graphite, giving the pipes the advantages of high strength, high elongation, impact resistance and good sealing. After long-term use, the outer wall of the pipe will produce more rust, requiring surface treatment of the ductile iron pipe.

[0003] Existing ductile iron pipes usually require manual use of grinding equipment to remove rust from the surface of the ductile iron pipes. This method has low rust removal efficiency, and manual operation will cause uneven force on the grinding area, resulting in unevenness, causing certain damage to the ductile iron pipes. In addition, manual grinding is not easy to rotate the ductile iron pipes, and the operation is inconvenient. Therefore, we propose a rust removal equipment for ductile iron pipe fittings.

By setting a rotating component, specifically starting a motor to drive the roller to rotate, the roller drives the ductile iron pipe to rotate, and the roller will rotate with the ductile iron pipe. Since the ductile iron pipe is rotated and polished, the rust removal efficiency can be improved, and the force is more uniform, reducing the occurrence of unevenness, and solving the problem that manual operation will cause uneven force in the polishing area, thereby causing certain damage to the ductile iron pipe, and manual polishing is not easy to rotate the ductile iron pipe, which is inconvenient to operate.
