Problems solved by technology

[0003] Existing drying devices generally use electric heating wires for drying, which need to provide a large amount of electric energy. During the sintering process, waste gas is generally discharged. When this part of the waste gas is discharged, it carries a lot of heat, resulting in a large amount of heat. loss

Abstract

The invention relates to the technical field of magnetic materials, and discloses a drying device for environmental-protection production sintering of ferrite magnetic powder. The drying device comprises a sintering box, an afterheat recovery device, a drying box and a dust removing device; the afterheat recovery device comprises an exhaust pipe, a first ventilation pipe, a first air sucking fan,a second ventilation pipe, a third ventilation pipe, an exhaust cover, a guide plate, a first exhaust hole, a fourth ventilation pipe and a third air sucking fan; and the dust removing device comprises a second air sucking fan, a positive plate, a negative plate, a separation plate, a dust removing box and a second exhaust hole. Through arrangement of the afterheat recovery device, waste gas exhausted through the exhaust pipe is fed in the drying box through the third ventilation pipe, the second ventilation pipe and the first ventilation pipe, and hot air is exhausted through the fourth ventilation pipe to form reflux, so that the purposes of drying through heat discharged by sintering, energy conservation and environmental protection are achieved, and the problems of consumption of a lotof electric power in traditional drying and no reasonable utilization of waste gas exhausted in sintering are solved.

Description

Technical field [0001] The invention relates to the technical field of magnetic materials, in particular to an environment-friendly drying device for producing sintered ferrite magnetic powder. Background technique [0002] Iron scale is one of the main raw materials for the production of ferrite magnetic powder. my country has started to use iron scale almost at the initial stage of establishing the ferrite magnetic powder industry. However, because the scale is affected by factors such as the type of steel and the collection situation, the composition is extremely unstable and contains many impurities. If it is not pre-treated, it is difficult to guarantee the magnetic properties of the ferrite. In order to make use of iron scale, which has a wide source and low price, to produce ferrite magnetic powder material with medium and high performance, it must be processed deeply. Usually the iron scale containing impurities is produced into ferrite magnetic powder after entering the...
