Description

Technical Field

[0001] The utility model relates to the technical field of iron ore processing, in particular to an impurity removal device used for iron ore mining equipment. Background Art

[0002] Iron is the earliest discovered, most widely used and most consumed metal in the world, accounting for about 95% of the world's total metal consumption. There are many types of iron minerals. There are more than 300 types of iron minerals and iron-containing minerals discovered, of which more than 170 are common. However, the phosphorus content in industrially used minerals such as magnetite, hematite, limonite and siderite is quite high, which affects the quality of the finished pig iron.

[0003] As disclosed in Chinese Patent Publication No. (CN213855652U), a de-impurity device for iron ore mining equipment belongs to the technical field of ore de-impurity devices. A de-impurity device for iron ore mining equipment includes a de-impurity box, fixed blocks are fixedly connected to the inner walls of the de-impurity box on both sides, a return spring is fixedly connected to the fixed block, a moving rod is connected to the upper end of the return spring, and a vibration plate is rotatably connected to the upper end of the moving rod through a rotating shaft. The utility model can make the dephosphorization agent fully contact with the iron ore to improve the dephosphorization effect through the arrangement of the driving mechanism, the telescopic mechanism, and the vibration plate. When the iron ore is vibrated, impurities such as dust on the iron ore can also be separated from the iron ore, thereby achieving de-impurity and dephosphorization of the iron ore. By setting the purification mechanism, harmful impurities in the waste liquid can be filtered to ensure that the liquid will not affect the environment. By setting the drying mechanism, the iron ore can be dried, which is convenient for users to carry out the next step.

This method adds a batch of ore to the impurity removal box for spraying and impurity removal, and then takes out the ore to add ore for impurity removal a second time. This will result in repeated steps of adding and taking materials, which seriously affects the impurity removal efficiency of iron ore mining. Utility Model Content
