Description
Technical field
The present invention relates to neodymium iron boron production equipment technical field, specifically, it is related to a kind of for neodymium iron boron storage vat
Interface structure.
Background technology
Neodymium-iron-boron magnetic material, the latest result developed as rare earth permanent-magnetic material, due to its excellent magnetic property by
Referred to as " magnetic king ".Neodymium-iron-boron magnetic material is praseodymium neodymium metal, the alloy of ferro-boron etc., also known as magnet steel.Neodymium iron boron has high magnetic
Energy product, coercivity and energy density, it is applied widely in modern industry and electronic technology, makes instrument and meter, electricity
Miniaturization, lightweight, the slimming of the equipment such as acoustic-electric machine, magnetic separation magnetization are possibly realized.
Contain substantial amounts of rear earth element nd, iron and boron in neodymium iron boron, its characteristic is hard and crisp.The advantage of neodymium iron boron is cost performance
Height, has good mechanical property；Be disadvantageous in that operating temperature is low, temperature characterisitic is poor, and be easy to dusting corrosion and easily by
Oxidation.
In existing neodymium iron boron manufacturing process, it usually needs using charging basket to being exported from airflow milling discharge outlet
NdFeB magnetic powder carries out splicing, storing.The charging basket more commonly used at present is typically made up of a cylindrical shape staving, is set on the charging basket
There is the material receiving port with the discharging opening matching of airflow milling, although it more convenient can carry out splicing to neodymium iron boron, but be due to neodymium
Iron boron is easily aoxidized in itself, and such barrel can not carry out completely cutting off while splicing to air, so as to cause neodymium iron boron
The very big reduction of quality.
Cause having its source in for above mentioned problem：During lacking one kind in the prior art specifically designed for such as neodymium iron boron splicing
The barrel used, and lack and a kind of can still possess the close of preferable sealing property during quick, multiple demolition, installation
Envelope mechanism.
