Titanium sponge secondary sorting and screening device and method

Abstract

The invention discloses a titanium sponge secondary sorting and screening device. The device comprises an oscillation hopper, a distribution mechanism, a sorting mechanism and a particle size screener; the vibration hopper is arranged on a rack; sponge titanium is provided for the distribution mechanism in a vibration process; a distribution device is arranged at the inlet of the distribution mechanism; the sponge titanium is uniformly spread; a magnetic separator is arranged at an outlet of the distribution mechanism; the sorting mechanism comprises a conveying mechanism and a sorting station; one end of the conveying mechanism is connected with the outlet of the distribution mechanism, and the other end of the conveying mechanism is connected with the feeding port of the particle size screener; the sorting station is located on one side or two sides of the conveying mechanism; and the particle size screener is used for screening titanium sponge with different particle sizes and collecting the titanium sponge into corresponding containers. The secondary sorting and screening method comprises a feeding process, a distributing process, a sorting process and a screening process. Withthe titanium sponge secondary sorting and screening device adopted, the problems of high labor intensity and low efficiency of the secondary sorting of titanium sponge can be solved; the particle sizes of the titanium sponge can be screened according to actual requirements; and high-quality titanium sponge can be provided for the smelting of high-end titanium materials.

Description

technical field [0001] The invention belongs to the field of nonferrous metal processing, and in particular relates to a secondary material selection and screening device and method for titanium sponge. Background technique [0002] Titanium and titanium alloys have the advantages of corrosion resistance, high specific strength, good biocompatibility, and non-magnetic properties. They are widely used in aerospace, chemical, medical and other fields. main raw material. The industry mainly uses magnesium reduction reaction to prepare sponge titanium, and the reaction formula is TiCl 4 +2Mg=Ti+2MgCl 2 , and then the MgCl in the titanium sponge is distilled 2 After separation and removal, titanium sponge lumps are obtained, and after cutting, crushing, mixing, and sorting, finished titanium sponges with a particle size of ≤25.4mm are obtained. In the production process of sponge titanium, it is inevitable to produce defective sponge titanium blocks, mainly including overburn...
