Detailed description of the invention
Below with reference to specific embodiment, the present invention and beneficial effect thereof are described in further detail, but,
The detailed description of the invention of the present invention is not limited to this.
If Fig. 1 is to shown in 5, the ceramic inner stator that the present invention provides, decided at the higher level but not officially announced including be made of ceramic materials
Sub-main body 1 and several stirrer gears being made of ceramic materials being arranged on the outer surface of inner stator main body 1
2.Ceramic material hardness is high, wear-resistant, and the pollution to material is little, inner stator main body 1 and stirrer gear 2
For integral type structure, stirrer gear 2 has good Centrifugal dispersion effect in rotation process, so that material
Particle size uniformity reach optimal.
In the circumference of the outer surface of inner stator main body 1, stirrer gear 2 is in spiral distribution.It is to say,
In the circumference of the outer surface of inner stator main body 1, stirrer gear 2 is not located on same circle, and is in
On helix, the stirrer gear 2 of Spiral distribution can increase the horizontal stroke of abrasive media and slurry during stirring
To flowing, thus improve the grinding to material and dispersibility so that the raw meal particle size after grinding is thinner, effect
Rate is higher.
In the short transverse of the outer surface of inner stator main body 1, stirrer gear 2 forms some row longitudinal arrangements
Denture, say, that in a vertical direction, stirrer gear 2 is vertically arranged, and is positioned at stirring of same denture
Teeth 2 is positioned on same vertical curve.
Stirrer gear 2 includes bottom 21, left surface 22, leading flank 23, trailing flank 24, right flank 25 and top
Portion 26, bottom 21 is connected with inner stator main body 1, and leading flank 23 is set to the arc-plane tilted, rear side
Face 24 includes that interconnective first tilts arc-plane 241 and second and tilt arc-plane 242, and the
Two area areas more than the first inclination arc-plane 241 tilting arc-plane 242, second tilts arc
Plane 242 is connected with right flank 25, and first tilts arc-plane 241 is connected with left surface 22, left surface
The area of 22 is more than the area of right flank 25.It is to say, the profile of stirrer gear 2 is not prim
Cuboid, but there is irregular shape, the specific surface area of the stirrer gear 2 of this structure is bigger, and
And there is certain tapering, therefore, it is possible to there is good Centrifugal dispersion and grinding effect.
Bottom 21 is formed with chimb 27 to its side, and for realizing the firm fixing of stirrer gear 2, first tilts
The incline direction that arc-plane 241 tilts arc-plane 242 with second is different, thus is formed therebetween convex
Rib, can improve dispersion grinding effect.
In same string denture, the height that distance is inner stator main body 1 between adjacent stirrer gear 2
1/10-1/3, this distance refers to the distance between the limit closed on of adjacent stirrer gear 2, the unsuitable cloth of stirrer gear 2
Putting get Tai Mi, the most easily get stuck, and be not easy to clean, stirrer gear 2 also should not be arranged to the dilutest, no
Then dispersion mixing effect is the best, it is impossible to meet actual grinding demand.Stirrer gear 2 is at the height of inner stator main body 1
The 3%-7% of the height that average thickness is inner stator main body 1 on degree direction.Stirrer gear 2 should not be the thickest, no
Then it is unfavorable for the raising of dispersion effect, increases load, also should not be the thinnest, it is easily damaged manufacture upper relatively difficult,
Manufacturing cost is increased.
The quantity of denture is 3-8 row, in the periphery of inner stator main body 1 upwards, the adjacent distance between denture
The most equal.In the present embodiment, the quantity of denture is 6 row, in 60 ° of angles, this knot between adjacent denture
The stirrer gear 2 of structure is not only convenient for manufacturing, and structure is attractive in appearance, and grinding effect might as well.
The lower end of inner stator main body 1 is downwardly projecting protuberance 11, in order to whole inner stator is installed to it
On his parts, the inwall at the upper opening of inner stator main body 1 is formed with the interior recess 12 that cross section is L-shaped,
Seal so that being formed in other parts are installed to inner stator.
Ceramic material is the zirconia material of stabilized with yttrium oxide, and wherein mole accounting of yittrium oxide is 0.1%-5%,
The preparation method of ceramic material is high temperature sintering, and temperature is 1400 DEG C-1560 DEG C, and the time is 0.3h-2h.Oxidation
Zirconium has high rigidity, high abrasion, good high high-temp stability and a thermal shock resistance, and zirconium oxide
Water insoluble, sulphuric acid, hydrochloric acid and nitric acid.Pure zirconium oxide, owing to can there is t-m phase transformation, is easily caused product
Fragmentation thus lose practical value, by zirconic crystal structure introduce Mg2+Displacement Zr4+Thus shape
Become solid solution, make tetragonal phase zirconium oxide to retain and at room temperature and no longer undergo phase transition, carry out Stable Oxygen with this
Change zircon ceramic material.Single Tetragonal can be obtained by the method for high temperature sintering and crystal grain refines, micro-knot
Structure is uniform, the zirconia ceramics material of the stabilized with yttrium oxide of function admirable.
In a word, the present invention at least has the advantage that
First, inner stator main body 1 and the stirrer gear 2 of the present invention are all made of ceramic materials, and it is compared
For general metal material, have that hardness is high, wearability is good and the advantage of length in service life；
Second, the present invention uses the stirrer gear 2 of the stirrer gear 2 and optimization that optimize design to be distributed so that this
Bright can provide good grinding effect, and grinding efficiency is high, thus reduce grinding cost.Specifically,
The stirrer gear of the present invention has good Centrifugal dispersion effect in rotation process, so that the granularity of material is equal
Even property reaches optimal.And the stirrer gear of Spiral distribution can increase abrasive media and slurry during stirring
Horizontal mobility, thus improve the grinding of material and dispersibility so that the raw meal particle size after grinding is thinner,
In hgher efficiency.
The announcement of book and teaching according to the above description, those skilled in the art in the invention can also be to above-mentioned
Embodiment carries out suitable change and amendment.Therefore, the invention is not limited in disclosed and described above
Some modifications and changes of the present invention be should also be as falling into the guarantor of the claim of the present invention by detailed description of the invention
In the range of protecting.Although additionally, employ some specific terms in this specification, but these terms are simply
Facilitate explanation, the present invention is not constituted any restriction.
