Specific embodiment
The present invention and its advantage are described in further detail below with reference to specific embodiment, still, this hair
Bright specific embodiment is not limited to this.
As shown in Fig. 1 to 5, ceramics inner stator provided by the invention, including 1 He of inner stator main body being made of ceramic materials
Several stirrer gears being made of ceramic materials 2 being arranged on the outer surface of inner stator main body 1.Ceramic material hardness is high, resistance to
Abrasion, and it is small to the pollution of material, and inner stator main body 1 and stirrer gear 2 are an integral structure, and stirrer gear 2 is in rotation process
With good Centrifugal dispersion effect, so that the particle size uniformity of material reaches optimal.
In the circumferential direction of the outer surface of interior stator body 1, stirrer gear 2 is in spiral distribution.That is, in interior stator body
In the circumferential direction of 1 outer surface, stirrer gear 2 is not located on same circle, but on helix, the stirring of Spiral distribution
Tooth 2 can increase the lateral flow of abrasive media and slurry during stirring, so as to improve the grinding to material and disperse
Ability so that the material size after grinding is thinner, more efficient.
In the short transverse of the outer surface of interior stator body 1, stirrer gear 2 forms the denture of several columns longitudinal arrangement,
That is in a vertical direction, stirrer gear 2 is vertically arranged, the stirrer gear 2 positioned at same denture is located at same vertical curve
On.
Stirrer gear 2 includes bottom 21, left surface 22, leading flank 23, trailing flank 24, right flank 25 and top 26, bottom 21
It is connected with inner stator main body 1, leading flank 23 is arranged to inclined arc-plane, and trailing flank 24 includes be connected with each other first and tilts
Arc-plane 241 and second tilts arc-plane 242, and the second area for tilting arc-plane 242 is more than first and tilts arc
The area of shape plane 241, the second inclination arc-plane 242 are connected with right flank 25, and first tilts arc-plane 241 and left surface
22 are connected, and the area of left surface 22 is more than the area of right flank 25.That is, the shape of stirrer gear 2 is not regular
Cuboid, but with irregular shape, the specific surface area of the stirrer gear 2 of this structure is bigger, and with certain
Taper, therefore can have good Centrifugal dispersion and grinding effect.
Bottom 21 is formed with chimb 27 to its side, is used to implement the firm fixation of stirrer gear 2, and first tilts arc-plane
The 241 inclined direction differences for tilting arc-plane 242 with second, so as to form fin therebetween, can improve scattered grinding
Effect.
In same row denture, the distance between adjacent stirrer gear 2 is the 1/10-1/3 of the height of inner stator main body 1,
The distance refers to the distance between adjacent side closed on of stirrer gear 2, and stirrer gear 2 should not be arranged to too close, otherwise easy card
Material, and does not allow easy cleaning, and stirrer gear 2 should not also be arranged to too dilute, it is bad otherwise disperse mixing effect, it is impossible to which satisfaction is actually ground
Mill demand.Average thickness of the stirrer gear 2 in the short transverse of interior stator body 1 is the 3%- of the height of inner stator main body 1
7%.Stirrer gear 2 should not be too thick, is otherwise unfavorable for the raising of dispersion effect, increases load, also should not be too thin, is easily damaged manufacture
It is upper relatively difficult so that manufacture cost increases.
The quantity of denture arranges for 3-8, and upward in the periphery of interior stator body 1, the distance between adjacent denture is equal.
In the present embodiment, the quantity of denture is 6 row, is not only convenient for making in 60 ° of angles, the stirrer gear 2 of this structure between adjacent denture
It makes, and structure is beautiful, and grinding effect might as well.
The lower end of inner stator main body 1 is downwardly projecting protrusion 11, in order to which entire inner stator is installed to other component
On, the L-shaped interior recess 12 in section is formed on the inner wall at the upper opening of inner stator main body 1, in order to by other components
It is installed in inner stator and forms sealing.
Ceramic material is the zirconia material of stabilized with yttrium oxide, and wherein mole accounting of yttrium oxide is 0.1%-5%, ceramic
The preparation method of material is high temperature sintering, and temperature is 1400 DEG C -1560 DEG C, time 0.3h-2h.Zirconium oxide have high rigidity,
High abrasion, good high high-temp stability and thermal shock resistance, and zirconium oxide is not soluble in water, sulfuric acid, hydrochloric acid and nitric acid.
Pure zirconium oxide is easy to cause product fragmentation so as to lose practical value, passes through the crystalline substance in zirconium oxide since t-m phase transformations can occur
Mg is introduced in body structure2+Replace Zr4+So as to form solid solution, tetragonal phase zirconium oxide is allow to retain at room temperature without sending out again
Raw phase transformation, carrys out stabilized zirconia ceramic material with this.Single tetragonal phase can be obtained by the method for high temperature sintering and crystal grain is thin
Change, uniform microstructure, function admirable stabilized with yttrium oxide zirconia ceramics material.
In short, the present invention at least has the following advantages that：
First, inner stator main body 1 of the invention and stirrer gear 2 are all made of ceramic materials, compared to general
For metal material, have the advantages that hardness is high, wearability is good and service life is long；
Second, the present invention is distributed using the stirrer gear 2 of optimization design and the stirrer gear 2 of optimization so that the present invention can carry
For good grinding effect, and grinding efficiency is high, so as to reduce grinding cost.Specifically, stirrer gear of the invention is turning
There is good Centrifugal dispersion effect, so that the particle size uniformity of material reaches optimal during dynamic.And Spiral distribution stirs
Teeth can increase the lateral flow of abrasive media and slurry during stirring, so as to improve the grinding to material and disperse
Ability so that the material size after grinding is thinner, more efficient.
