Fluorination device for treating neodymium iron boron waste powder

Abstract

The invention discloses a fluorination device for treating neodymium iron boron waste powder, and belongs to the technical field of neodymium iron boron waste treatment. The fluorination device comprises a fluorine gas generating device, and a top outlet of the fluorine gas generating device is connected with a corrugated pipe. The right side wall of the fluorine gas generating device is connectedwith a reaction pipe through a screw, and the top of the left end of the reaction pipe is connected with a gas inlet. The gas inlet is connected with the bottom of the right end of the corrugated pipe, and spoilers are evenly mounted on the left side wall of an inner cavity of the reaction pipe. The upper side of the middle of the reaction pipe is connected with a charging opening, and a protection cover is mounted in the middle of the upper side wall of the inner cavity of the reaction pipe. The protection cover is connected with the bottom of the charging opening, and the bottom of the reaction pipe is connected with an arc-shaped reaction bin. According to the fluorination device for treating the neodymium iron boron waste powder, by arranging the spoilers, the flow velocity of fluorine gas can be reduced; by arranging the protection cover, gas flow is prevented from blowing away the raw material powder; and by arranging a gas pressure inductor and a PLC, the intelligent control degree is higher.

Description

technical field [0001] The invention relates to the technical field of NdFeB waste treatment technology, in particular to a fluorination device for NdFeB waste powder treatment. Background technique [0002] At present, NdFeB permanent magnet materials have been widely used in various fields such as aerospace technology, computer equipment, magnetic separators, communication equipment, medical equipment, electric bicycles, and electronic toys. In the production process of NdFeB permanent magnet materials, many available waste materials are wasted. The powder waste with high oxygen content is one of them. It is necessary to remove the oxygen element in the powder waste. For this reason, we A fluorination device for NdFeB waste powder treatment is proposed. Contents of the invention [0003] The purpose of the present invention is to provide a kind of NdFeB waste material powder processing fluorination device, to solve the problem that many available waste materials are was...
