A kind of ultrasonic wave batch mixer for ceramic powder
Technical field
The present invention is a kind of ultrasonic wave batch mixer for ceramic powder.
Background technology
Before bulletproof ceramic sintering, need uniformly to mix raw material, relatively traditional mixing method has artificial batch mixing, ball
Grind batch mixing and mechanical batch mixing.
For artificial batch mixing, powder is poured into blender, water is added tentatively to be stirred, then carried out repeatedly with pore sieve
Sieve material judges that the uniformity of powder, this method not only need to occupy a large amount of manpowers by constantly detecting, increases cost input,
There is strict demand to the type of powder simultaneously, other than the smaller pure powder powder of grain size, for containing additive or composite powder
Material, artificial batch mixing lack of homogeneity are susceptible to the unevenness of sintered products, cause product rejection, the increase of cost.
There is large increase for ball mill mixing, for uniformity is relatively artificial, but still has part production in sintered products
There is the case where particle aggregation in product, illustrate that the uniformity in mixing process is not up to theory calls, meanwhile, ball milling take compared with
Length, powder are limited, are suitable for experiment research and development and are not suitable for mass production, in turn result in the limitation of production.
For mechanical batch mixing, the mixing equipment used in ceramic industry has high speed mixer, although useful load is big, but still has
The case where powder is reunited;High speed mixer further can not make powder granule become smaller simultaneously, for containing additive
Powder, batch mixer are difficult to smash additive and be uniformly blended into ceramic powder, and only play the role of a stirring.
Invention content
The object of the present invention is to provide it is a kind of be simple to manufacture, easy to operate ceramic powder ultrasonic wave batch mixer, solve
In bulletproof ceramic production process the problem of batch mixing unevenness, inefficiency.
In order to achieve the object of the present invention, using following technical proposals:Ceramic powder ultrasonic wave batch mixer is used for shellproof pottery
The mixed uniformly equipment of porcelain powder, including barrel, vibration whistle, electric-motor pump, pressure gauge, connecting tube.
The present invention is put into batch mixer in order to make powder be sufficiently mixed uniformly, by mixing the raw material of required mixing in proportion
It is interior, make it that flow-like be presented, the flowing of fluid powder is driven by motor, vibration whistle is made it through, when motor speed reaches certain
When one critical value, the powder quickly flowed generates Hydrokinetic ultrasonic by vibrating whistle, in the irradiation process of ultrasonic wave,
Fluid powder flows and generates ten hundreds of micro-bubbles, and the micro-bubble being present in fluid shakes under the action of sound field
Dynamic, when acoustic pressure reaches certain value, bubble increases rapidly, and is then closed suddenly, generation shock wave and micro- is penetrated when bubble is closed
Stream, thousands of a atmospheric pressure are generated around it, disperse the powder particles to keep together, achieve the effect that it is evenly dispersed, simultaneously
Powder is constantly hit in vibration processes, moreover it is possible to generate the effect of micronized particles.
The advantages of batch mixer of the present invention is:
Equipment operation is simple, and batch mixing work can be completed in one, improves personnel's utilization rate.
Fluid powder impacts reed by whistle makes it generate Hydrokinetic ultrasonic, keeps powder lot dispersing more uniform, together
When powder particles it is more tiny, be conducive to later stage sinter molding, improve performance.
The batch mixing period is short, and low energy consumption, and production efficiency is high.
Description of the drawings
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is ceramic powder ultrasonic wave batch mixer structural schematic diagram.Each label indicates 1 barrel, 2 vibration whistles, 3 electricity in figure
Pump, 4 pressure gauges, 5 connecting tubes.
Specific implementation mode
Embodiment 1:
According to Fig. 1, using stainless steel material by size requirement processing and fabricating all parts, strict tolerances range.Most
It is completed ceramic powder ultrasonic wave batch mixer as shown in the figure eventually
Embodiment 2:
Mixed powder, binder, water will be needed to be mixed and made into flow-like by required proportioning, pour into batch mixer, open motor,
It drives powder to be flowed in pipe, adjusts motor speed.Achieve the effect that tentatively to mix.
Embodiment 3:
The flowing of fluid powder, fluid powder is driven so that particle agglomerated together is obtained under the action of vibrating whistle by motor
With dispersion, to realize the uniform mixing to powder, crystal grain refinement.
