| titleOfInvention | Hollow steel phosphorus removal device for super strength drill rod |
| abstract | The utility model discloses a hollow steel phosphorus removal device for super-strength drill rods. The hollow steel phosphorus removal device aims to solve the technical problem that the phosphide attached to the inner wall of the current hollow drill rod is not easy to remove and affects the use performance of the drill rod. The hollow steel phosphorus removal device includes a fixed base installed on the upper end of the drill rod, an installation cavity disposed in the middle of the fixed base, an air channel disposed inside the installation cavity, and a storage box installed at the lower end of the air passage. , an air pump arranged on the right side of the fixed pedestal. The hollow steel phosphorus removal device adopts the method of spraying high-speed inert gas into the hollow drill rod by an air pump, and the high-speed airflow rolls the metal ball on the inner wall of the drill rod to continuously strike back and forth. The attached phosphide is knocked and peeled off, the phosphide removal effect is good, the damage to the drill rod is small, the inert gas does not have an oxidation reaction with the surface of the steel drill rod, and the chemical properties of the inner wall of the drill rod are relatively stable. |
