Description
Technical field
The utility model belongs to dusty material synthesis technique apparatus field, is specifically related to a kind of heating and ball-milling integrated tube furnace.
Background technology
At present in dusty material synthetic, most materials, for example anode material for lithium-ion batteries LiCoO
2, LiMnO
2, LiFePO
4Deng, the synthesis condition that needs comprises high-temperature process and two steps of ball-milling treatment, the former is the material that has the target crystal structure for synthetic, the latter then is in order to control the granularity of product, introduce synthetic special atmosphere, for example argon gas of also needing of suitable finishing or the like, particularly some material, nitrogen, or the air of oxygen enrichment or the like.
In the prior art; high-temperature process adopts tube furnace to carry out usually; ball-milling treatment then has special ball-grinding machine; what adopt is two relatively independent complete equipments; after the high-temperature process; take out sample and place the ball-grinding machine ball milling again, and usually also need high temperature to handle again after the ball-milling treatment, need under some condition repeatedly for several times.
The problem that exists in the at present aforesaid two step building-up processes is conspicuous; the transfer of material is labor intensive not only; reduce the equipment automatization level; and at synthetic atmosphere (anhydrous condition for example relatively under the specific conditions; nitrogen, argon gas, perhaps oxygen enrichment or the like); transfer process usually can be polluted synthetic material, improves the synthetic cost of material.Under this background condition, design and develop new particularly important that high-temperature process and ball-milling treatment integrated synthesis device show of melting.
Summary of the invention
