Description
Technical field
The present invention relates to nd-fe-b production facilities technical field, specifically, relating to a kind of storage device for collecting NdFeB magnetic powder.
Background technology
Neodymium-iron-boron magnetic material, as the latest result of rare earth permanent-magnetic material development, is called as due to the magnetic property of its excellence " magnetic king ".Neodymium-iron-boron magnetic material is praseodymium neodymium metal, and the alloy of ferro-boron etc., also known as magnet steel.Nd-fe-b has high magnetic energy product, coercive force and energy density, and it is applied widely in modern industry and Eltec, makes the miniaturization of the equipment such as instrument and meter, electroacoustic motor, magnetic separation magnetization, lightweight, slimming become possibility.
Containing a large amount of rear earth element nd, iron and boron in nd-fe-b, its characteristic is hard and crisp.The advantage of nd-fe-b is that cost performance is high, the mechanical specialities that tool is good; Weak point is that operating temperature is low, and temperature characterisitic is poor, and is easy to dusting corrosion and very easily oxidized.
In existing nd-fe-b manufacturing process, employing charging basket is usually needed to carry out splicing, storing to the NdFeB magnetic powder exported from airflow milling discharge outlet.Charging basket comparatively conventional at present is generally made up of a cylindrical shape staving, this charging basket is provided with the material receiving port matched with the discharging opening of airflow milling, although it comparatively conveniently can carry out splicing to nd-fe-b, but because nd-fe-b itself is very easily oxidized, and such barrel cannot completely cut off air while splicing, thus cause the very big reduction of nd-fe-b quality.
Cause having its source in of the problems referred to above: lack a kind of special in the barrel used in such as nd-fe-b splicing process in prior art, and lack a kind of can fast, still can possess the sealing mechanism of better sealing property in repeatedly demolition, installation process.
