Abstract

The invention relates to iron oxide powder producing equipment, in particular to an iron oxide powder dechlorinating device and a control method thereof. The iron oxide powder dechlorinating device comprises a controller, a frequency converter and a screw conveyor, wherein the screw conveyor is connected to an iron oxide powder conveying pipe through a feed opening and a discharge opening thereof;a driving motor of the screw conveyor is connected with the frequency converter; a high-temperature vaporization desalination water mechanism is arranged at the tail part of the screw conveyor; the high-temperature vaporization desalination water mechanism is controlled by the controller and sprays high-temperature vaporization desalination water into iron oxide powder in the screw conveyor; thehigh-temperature vaporization desalination water gas flow and the iron oxide powder flow in reverse directions. The iron oxide powder dechlorinating device can effectively remove chloride ions in theiron oxide powder without affecting the contents of other components of the iron oxide powder, and the high-temperature gas flow can also dehumidify the iron oxide powder, so that the quality and thepurity of the iron oxide powder are guaranteed; the iron oxide powder dechlorinating device has the characteristics of continuous dechlorination, automatic control, a compact structure, stable and reliable operation, large treating capacity, low operating cost and a long service life.

Description

technical field [0001] The invention relates to iron oxide powder production equipment, in particular to an iron oxide powder chlorine removal device and a control method thereof. Background technique [0002] Iron oxide powder is mostly used to make ferrite magnetic materials. Ferrite is an important type of electronic device, mainly used to manufacture various inductive components, such as magnetic cores for filters and transformers, magnetic heads for tape recorders and video recorders, etc. The preparation of ferrite magnetic materials requires high-purity iron oxide powder, and the chloride ion content is an important detection item of iron oxide powder, and its content directly affects the physical properties of iron oxide powder. Therefore, the preparation of iron oxide powder with high purity and good physical properties must control its chloride ion content. [0003] At present, the content of chlorine in iron oxide powder is controlled by the production process of...
