Embodiment 1

[0086] This embodiment provides a centrifugal separation device for separating titanium resources in titanium-containing materials, such as figure 1 Said, the device includes a centrifugal power transmission system, a centrifuge drum 5, a crushing system and a feeding system; wherein, the centrifuge drum 5 is covered with a temperature control heating jacket 4, and one end of the centrifuge drum 5 is The central axis of the centrifuge is connected to the centrifugal power transmission system, and the other end is provided with an opening covered with a cover plate. When the centrifuge drum 5 needs to be fed, the feeding device 6 is connected to the opening covered with the cover plate.

[0087] Wherein, the centrifuge drum 5 is a cylindrical cylinder, and there is no ceramic lining inside it. The centrifuge drum 5 rotates in the vertical direction, and its shell is an outer wall formed by a three-layer steel structure. The outside is the first layer steel structure, the second...

Embodiment 2

[0092] This embodiment provides a centrifugal separation device for separating titanium resources from titanium-containing materials. The structure of the device refers to the structure of the device in Embodiment 1, the only difference being that the centrifuge drum 5 is not covered with a temperature control heating jacket 4 .

Embodiment 3

[0094] This embodiment provides a centrifugal separation device for separating titanium resources from titanium-containing materials.

Abstract

The invention provides a centrifugal separation device for separating titanium resources from an titanium-containing material and a processing method of the centrifugal separation device. The centrifugal separation device comprise a centrifugal power transmission system and a centrifuge drum; the central axis part of one end of the centrifuge drum is connected with the centrifugal power transmission system, and an opening covered with a cover plate is formed in the other end of the centrifuge drum; and a feeding opening is formed. According to the device and the method, in the process that a molten titanium-containing material is cooled to 1300 DEG C from 1600 DEG C, titanium in the titanium-containing material is controlled to be enriched in a black-titanium-stone high-titanium crystal phase, meanwhile, the precipitated black titanium stone is enriched by utilizing the action of centrifugal force, and subsequent separation is carried out to obtain high-grade titanium slag with the TiO2 grade of more than 76%, so that the titanium extraction upgrading of the low-grade titanium-containing material can be realized, and a new idea and method are provided for comprehensive utilizationof vanadium titano-magnetite.

Description

technical field [0001] The invention belongs to the field of metallurgy, and relates to a centrifugal separation device for separating titanium resources from titanium-containing materials and a processing method thereof, in particular to a high-temperature centrifugal separation device for separating titanium resources from titanium-containing materials and a processing method thereof. Background technique [0002] The existing method of treating vanadium-titanium magnetite by direct reduction-melting process can enrich titanium while extracting iron, and obtain TiO 2 Melted titanium slag with a content of more than 40%, this type of titanium slag contains higher SiO 2 、Al 2 o 3 , CaO and MgO and other non-ferrous impurities, it is difficult to use the subsequent sulfuric acid method; 2 and Al 2 o 3 The leaching rate is low, and it is difficult to obtain high-quality titanium raw materials that meet the requirements of boiling chlorination. Therefore, if impurity remo...
