Description
Technical field
The utility model is related to ultra-fine powder technology field, more particularly to a kind of surface modification device of superfine powder.
Background technology
It is powder-modified to be broadly divided into two major class, modifying agent is carried out by the method for chemistry and certain groups of powder surface
The method so as to be directly incorporated on powder is reacted in-situ modified；Modifying agent is wrapped in the table of powder by the method for physics
The method package in face is modified.For different powder surface property, using different methods, and according to different in various methods
Inorganic agent property, and different technique is used, existing treatment process is mainly the following:
1st, the continuous surface treatment process of fluidized bed type, be by the inorganic agent after vaporization in fluid bed with powder it is opposite or
Person inversely contacts, so that inorganic agent comes into full contact with powder under certain process conditions, is mostly used in in-situ modified.But sulphur
The shortcomings that changing bed reaction is to be only capable of being suitble to vaporizable inorganic agent, can not then ensure the equal of mixing when inorganic agent can not vaporize
Even property, and reaction temperature more higher than inorganic agent must also be kept in fluid bed, the inorganic agent being otherwise vaporized is again easily cold
Congeal into liquid cause to contact it is uneven.Secondly the reaction time is short, because of the equipment limit of fluid bed in itself, when such as extending reaction
Between then need greatly to amplify fluid bed bed body, equipment investment and technology controlling and process there are it is certain the defects of.
2nd, closed autoclave modified device is heated up and stirs, advantage after inorganic agent and powder are added in confined space simultaneously
It is that can freely control the reaction time, but a disadvantage is that the inorganic agent after the inorganic agent that liquid phase adds in is vaporized with the later stage is contacted with material
When concentration ratio difference can cause partial material reaction or package it is uneven, secondly the inorganic agent after being vaporized is close
Closing in container easily leads to reservoir overpressure and safety accident occurs.The third is by-product can not remove, powder need to be finished in reaction
It is removed after sedimentation by other methods completely, process is extremely complex.The fourth is if powder water content may cause to change when higher
The hydrolysis of property agent.
3rd, it is typically that powder is equably conveyed the screw feeder into a squash type by a hopper that modifying machine, which is modified,
Equipment, modifying agent is injected in screw(-type) feeder simultaneously to be mediated with powder, is mostly used in package and is modified.The advantages of this method
It is mandatory so that powder is contacted with modifying agent.Shortcoming be powder after squash type screw feeder equipment, the powder of script
Body may be compressed, and after especially wrapping up modifying agent on surface, is more easily compressed into graininess even pie, need to be crushed ability again
Keep the performance of powder.Secondly screw feeder equipment can not accurately control reaction temperature, often most of modifying agent needs
It could effectively be combined with powder at certain temperature, and modifying machine can only be taken to reach corresponding temperature to equipment entirety
The method of heating.Lead to life of equipment serious curtailment, and there are certain security risks.
Utility model content

Inorganic agent atomising device is also connected on reaction kettle；
Agitating device is equipped in reaction kettle, heater is equipped in the outside of reaction kettle.
Based on the above technical solution, there can be technical solution further below：
The inorganic agent atomising device includes storage tank, and storage tank connects atomizer, atomizer setting by pipeline
In the reaction kettle, and hydraulic pump is connected on pipeline.
The heater uses electromagnetic induction heater.
Return duct is equipped in the side of the reaction kettle, the both ends of return duct are connected to the upside of reaction kettle under
Side is also connected with high-pressure pump on return duct.
Dust accumulation pipe is also connected on the upside of the reaction kettle, connects air hose in the downside of reaction kettle, dust accumulation pipe and air hose it
Between connect bag filter.
The agitating device includes motor, motor connection agitating paddle, and agitating paddle is arranged on the downside inside the reaction kettle.
Also be connected cover board on the feeding port.
The utility model has the advantage of：Present apparatus reaction kettle avoids the risk of reaction under high pressure, safety using gerotor type
Coefficient is high, the incomplete gas circulation of reaction is made to enter reaction kettle, while regulate and control stirring electricity according to powder difference by return duct
Machine rotating speed, temperature of reaction kettle and free control material residence time, material is effectively ensured and fully reacts, the bag-type dust of outfit
Device except byproduct of reaction can effectively be removed to the dust for being collected simultaneously and being taken out of with by-product, lead to by effectively control environmental protection, the present apparatus
Cross that electromagnetic heating mode avoids conventional heat-conducting oil heating or heating rod heating, risk existing for during because being in direct contact add
Thermal velocity is fast, and temperature is stablized, and can be used for the powder for needing to be dehydrated pretreatment simultaneously.
