Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of oil, gas and water treatment, in particular to a rust-removing grinding tool for flange nuts in an oil, gas and water treatment system. Background Art
[0002] Rust removal is a technology that uses chemical, electrochemical, mechanical and other methods to remove oxides from the surface of equipment and its parts. It is a method of removing rust from metal surfaces by various means. Common rust removal methods include manual rust removal, electric tool rust removal, spray or projectile rust removal, chemical rust removal, etc. At present, the most widely used mechanical rust removal strategies are needle gun rust removal and wire brush high-speed rotation rust removal. They are mainly used in planes or steel structures with relatively large space and range. They are less practical and less efficient for rust removal of compact and dense nuts on flanges.
[0003] GB / T 8923-2008 "Rust Removal and Rust Prevention Test Methods for Steel Surface Treatment" is a commonly used rust removal grade standard in China, which aims to specify the methods, processes and signs for rust removal of steel surface treatment. This standard divides rust removal grades into four levels: Sa1, Sa2, Sa2.5, and Sa3, of which Sa3 is the highest level, and the surface is completely rust-free, and impurities such as rust and dirt are completely removed. At the Sa2.5 level, a small amount of rust plaques are allowed to remain on the surface, but the surface must be clean and without obvious or local floating rust. At the Sa2 level, the floating rust allowed to remain on the surface is less than 5%, and the surface is clean, but there is visible slight pollution.
[0004] In actual application, due to the relatively compact space between flange nuts, the inside of the rusted nut is in the blind spot of the action. Using a needle gun or grinder for anti-corrosion cannot quickly and effectively remove surface rust or floating rust. More rust plaques will remain on the rusted surface in a small space, resulting in poor anti-corrosion effect and prone to secondary corrosion. Summary of the invention

[0007] Furthermore, the connecting head includes a four-way power connecting head, a threaded connecting head and a hexagonal power connecting head. During operation, one of the connecting heads is selected to be detachably fixedly connected to the upper end of the connecting rod; when the driving component is an electric handheld electric drill, the connecting head is selected as a four-way power connecting head; when the driving component is a pneumatic grinder, the connecting head is selected as a threaded connecting head; when the driving component is an electric grinder, the connecting head is selected as a hexagonal power joint structure.
[0008] Furthermore, the upper and lower ends of the connecting rod are respectively threadedly connected to the connecting head and the working head, and the thread directions of the upper and lower ends of the connecting rod are opposite.
[0009] Furthermore, the connecting head, connecting rod and supporting seat are made of stainless steel or iron.
[0010] Furthermore, the working heads are provided in plurality, and the inner cavities of the plurality of working heads are of different sizes, respectively corresponding to flange nuts of various sizes.
[0011] The beneficial effect of the utility model is that the above structure can realize all-round anti-corrosion and rust removal for flange nuts with compact space. The working process can quickly and effectively remove surface rust and floating rust, which greatly reduces the workload and improves efficiency, shortens the operation time, prevents incomplete rust removal and avoids the occurrence of secondary corrosion.
