Description

Technical Field

[0001] The utility model relates to the technical field of powder washing and drying, in particular to a water washing and drying device. Background Art

[0002] SmFeN is a permanent magnet material with excellent comprehensive magnetic properties. It has good corrosion resistance and oxidation resistance and does not contain strategic metal elements. Compared with other permanent magnet materials, SmFeN does not need to consume expensive rare earth elements, which makes SmFeN a potential new permanent magnet material. At present, the mainstream method for preparing high-purity SmFeN is the calcium thermal method. However, in the process of preparing SmFeN, impurities such as calcium ions will inevitably be introduced, which will affect the magnetic properties of SmFeN. Therefore, decalcification of SmFeN is one of the key steps to improve the magnetic properties of SmFeN.

[0003] In the related art, water washing is usually used to reduce the calcium content in SmFeN magnetic powder products, and the importance of water washing to remove calcium cannot be ignored.

The existing washing and drying processes need to be carried out in two separate devices, which will result in low efficiency of water washing to remove calcium and incomplete removal of calcium ions; in addition, if oxygen is present during the drying process, oxygen will seriously affect the quality and performance of the SmFeN magnetic powder product.

[0045] In the specific implementation process of the embodiment of the present application, the heating rate of the heating component 20 is set to 5°C per minute to 10°C per minute, and the first control valve 51 is opened to convey inert gas into the washing outer barrel 10 through the air supply pipe 50, and the heat is transferred to the samarium iron nitrogen magnetic powder through the air flow. The actual heating rate of the samarium iron nitrogen magnetic powder is 3°C per minute to 8°C per minute. At the same time, the washing inner barrel 11 rotates at 5 to 10 revolutions per minute to ensure the uniformity of the heating of the samarium iron nitrogen magnetic powder. Preferably, when the heating rate deviation is set to no more than 2°C per minute during the heating stage in the equipment, the samarium iron nitrogen magnetic powder is heated more evenly, and the temperature deviation of the samarium iron nitrogen magnetic powder particles does not exceed 1°C.

[0048] In the embodiment of the present application, the diameters of the multiple mesh holes of the filter are all 2 cm.

[0049] Specifically, the material to be washed is a samarium iron nitrogen magnetic powder product. When the filter mesh number is between 100 and 200 meshes, the effect of dispersing the magnetic powder is not obvious.

Preferably, the filter mesh number is greater than 200 meshes. Further, when the filter mesh number is greater than 400 meshes, under the same dehydration process conditions, the water content in the magnetic powder after dehydration accounts for 65% of the mass of the magnetic powder. Therefore, it is more preferred that the filter mesh number is 200-400, so that the filter can not only ensure the barrier effect of the filter on the samarium iron nitrogen magnetic powder and ensure the magnetic powder yield, but also avoid the problem of slow dehydration of metal powder due to excessive filter mesh isolation.
