Description

A kind of anaerobic ball grinding method and device
Technical field
The present invention relates to a kind of anaerobic ball grinding method and devices, belong to material grinding technique field.
Background technique
Ball milling is a kind of traditional and widely applied powder preparation method, with the extension and nanometer skill of power applications range The development of art has become one of the key method of powder preparation.Ball-milling method is although simple to operation, but suitable in order to obtain The powder of partial size or structure but needed to select suitable ball grinder in the experimental stage, and by repeatedly regulating and controlling ratio of grinding media to material, ball milling speed The conditions such as degree and ball-milling additive.For metal powder, need to carry out ball milling under anaerobic, to prevent sample It aoxidizes and influences grinding efficiency and sample quality.
The method of anaerobic ball milling mainly carries out in vacuum ball grinder at present.
Vacuum ball grinder is generally mostly metal material can be by close because metal material is conducive to that sealing system is made Capping is sealed.For the ball grinder of the materials such as the ball grinder that other can not directly be sealed, such as zirconium oxide, nylon, agate, Corresponding hermetically sealed case can only be generally prepared according to its material and size, and ball grinder is sealed again as in hermetically sealed case. The preparation of both the above sealing ball grinder requires to carry out special preparation according to its material and size, therefore complex process and valence Lattice are expensive.With the extension of use time, sealing cover or seal there is also abrasion or deformation, cause sealing effect bad.
In the laboratory exploratory stage, the case where for selecting the ball grinder of which type of material and size to be also not sure Under, the vacuum ball grinder for selecting any one expensive is all likely to result in the waste of resource and funds.
Summary of the invention
The object of the present invention is to disclose one for some limitations and problem existing for existing vacuum ball grinder ball-milling technology Kind anaerobic ball grinding method and device.
The technical solution that the present invention realizes is as follows, and ball grinder is packed into vacuum packet by a kind of anaerobic ball grinding method, the method Pack, is evacuated and hermetically sealed vacuum packaging bag;The ball grinder that vacuum bag seals is placed on ball mill, with clamp Carry out anaerobic ball milling.
A kind of anaerobic ball grinding method, steps are as follows:
(1) selection can load the vacuum packaging bag of ball grinder and the vacuum sealer suitable for the packaging bag;
(2) ball grinder, vacuum packaging bag and vacuum sealer are put into glove box;
(3) after ball grinder installs sample in glove box, ball grinder is placed in vacuum packaging bag;
(4) vacuum bag is evacuated and hermetically sealed;
(5) ball grinder that vacuum packaging bag seals is placed on ball mill, ball milling can be carried out with clamp.
The vacuum packaging bag is polybag or aluminium foil bag.
One layer of bubble chamber film plastic paper is padded between the fixture and the vacuum packaging bag for wrapping up ball grinder, prevents fixture from damaging Vacuum packaging bag.
A kind of device for realizing anaerobic ball milling, including ball mill, ball grinder, glove box, vacuum packaging bag and vacuum seal Machine;The ball grinder is evacuated and hermetically sealed in vacuum packaging bag by vacuum sealer;Vacuum packaging bag equipped with ball grinder Vacuum-pumping density is honored as a queen to install and is placed on the fixture of ball mill;Vacuum packaging bag equipped with ball grinder carries out under the clamping of fixture Anaerobic ball milling.
One layer of bubble chamber film plastic paper is padded between the fixture and the vacuum packaging bag for wrapping up ball grinder.
The ball grinder be it is columnar structured, it is open at one end to be provided with cover;Be lined between cover and ball grinder rubber or The material of plastic seal ring cover is identical as ball grinder material.
The glove box is placed in it to grind materials and stainless steel ball for ball grinder, and is packed into vacuum packaging bag, is taken out Vacuum sealing.
The vacuum sealer is used to that the vacuum packaging bag equipped with ball grinder to be vacuumized and be sealed.
The ball mill be vertical structure, including steel cylinder frame, fixture, screw rod, take off bridge, fastening nut, screw rod spanner and Live spindle;The steel cylinder frame is columnar structured, upper end opening, and lower end base is mounted on the live spindle of vertical level On, the top of two sides has gin pole framework slot;Fixture is made of upper fixture and lower fixture, in vertical direction opposite fortune It is dynamic;The lower fixture of fixture is mounted on steel cylinder frame bottom, and the axis of live spindle is overlapped with steel cylinder frame axis;The upper fixture of fixture One end is mounted on one end of screw rod;The top of screw rod is mounted in the screw hole in the middle part of gin pole frame;Gin pole frame both ends hook, can It is respectively protruding into the gin pole framework slot of steel cylinder frame two sides;The screw rod other end is equipped with screw rod spanner;It screw rod spanner and takes off between bridge Screw rod on, be equipped with fastening nut;It, will be upper by adjusting screw rod spanner when being equipped with ball grinder between fixture under upper fixture Lower clamp, then by adjusting fastening nut, bridge will be taken off and screw rod fastening is locked.
The ball mill is rotated by power drive live spindle, so that ball grinder be driven to carry out anaerobic grinding.
The ball grinder material is agate or zirconium oxide.
The invention has the advantages that ball grinder of the present invention for various material and size, can fast implement Ball milling is carried out under oxygen free condition;Because being not necessarily to expensive vacuum ball grinder or additional hermetically sealed case, call for bids lattice are low Honest and clean vacuum sealer and vacuum bag, therefore the cost that the present invention is implemented substantially reduces.Operation of the present invention is easy, simultaneously without design Manufacture complicated vacuum seal container or hermetically sealed case.
