DETAILED DESCRIPTION

[0028] Now the utility model is further described in detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the utility model in a schematic manner, and therefore only show the components related to the utility model.

[0029] like Figure 1-Figure 9 The specific embodiment of the slurry high-speed dispersion device of the utility model shown in the figure comprises a frame 1, a power assembly 2 is installed on the frame 1, a rotating shaft 3 is coaxially connected to the output end of the power assembly 2, a primary dispersion assembly 4 and a secondary dispersion assembly 5 are sequentially stacked and assembled on the rotating shaft 3 from bottom to top, a lower end cover 6 with a feed inlet is fixed to the bottom end of the primary dispersion assembly 4, the top of the secondary dispersion assembly 5 is fixed to the lower surface of the frame 1 through a machine seal seat 7, a discharge port 8 is provided on the machine seal seat 7, the inner cavity of the primary dispersion assembly 4 is connected to the discharge port 8, and the inner cavity of the primary dispersion assembly 4 is connected to the secondary dispersion assembly 5. The inner cavities of the components 5 are interconnected, and the inner cavity of the secondary dispersion component 5 is interconnected with the discharge port 8; the power component 2 drives the primary rotor 41 and the secondary rotor 52 to rotate at high speed, so that the material passes through the matching gap between the rotor and the stator in the primary dispersion component 4 and the secondary dispersion component 5 and impacts the outer wall of the stator at a very high speed from the edge of the rotor. Under the action of strong power, the material is subjected to strong shear force in the narrow gap between the stator and the rotor, so that the material mixing effect is better, and the mixing quality and mixing efficiency can be effectively improved. The material is dispersed and mixed through the secondary dispersion component 5 to further improve the mixing effect.

[0030] The primary dispersion component 4 includes a primary stator 40 fixed on the lower surface of the secondary dispersion component 5 and a primary rotor 41 sleeved and fixed on the rotating shaft 3; the primary stator 40 includes a primary stator seat 400 and a plurality of primary dispersion teeth 401 distributed in a circumferential array fixed on the primary stator seat 400, the primary stator seat 400 is arranged in a circular ring shape, the primary dispersion teeth 401 are equidistantly fixed on the inner circle of the primary stator seat 400, the primary rotor 41 includes a primary rotor seat 410 sleeved and fixed on the rotating shaft 3 and a plurality of arc cutters 411 distributed in a circumferential array fixed on the lower surface of the primary rotor seat 410, and the arc cutters 411 are close to one end of the dispersion teeth. The primary channel 42 for the slurry to pass through is formed between the outer wall of the primary dispersing teeth 401 and the inner wall of the primary stator seat 400, which are staggered with the tooth grooves. A rotor spacer 16 is arranged between the primary rotor 41 and the secondary rotor 52, and the rotor spacer 16 is sleeved on the output shaft of the power assembly 2. The primary stator seat 400 and the secondary stator seat 510 are a superimposed assembly structure. The primary rotor 41 rotates at a high speed under the power drive, and a pressure difference is generated between the center and the outer edge of the primary rotor 41, so that the material is continuously sucked in from the feed port. Under the rotation of the primary electron, the material passes through the tooth grooves of the primary dispersing teeth 401 and enters the primary channel 42, realizing the primary shear dispersion of the material. Due to the high tangential speed generated by the high-speed rotation of the rotor and the strong kinetic energy brought by the high-frequency mechanical effect, the material is subjected to the combined effects of strong mechanical and hydraulic shear, centrifugal extrusion, liquid layer friction, impact tearing and turbulence in the gap of the primary dispersing teeth 401, and is instantly sheared and dispersed. After high-frequency reciprocating, the mixed product is finally obtained, which can effectively improve the mixing effect.

[0031] The secondary dispersion component 5 includes a secondary stator 51 fixed on the lower surface of the machine seal seat 7 and a secondary rotor 52 sleeved and fixed on the rotating shaft 3. The secondary stator 51 includes a secondary stator seat 510 and a plurality of secondary dispersion teeth 511 distributed in a circular array and fixed on the secondary stator seat 510. A plurality of through holes 12 and secondary through holes 12520 are evenly spaced on the secondary rotor 52. The secondary dispersion teeth 511 and the through holes 12 and secondary through holes 12520 are staggered. A secondary channel 53 for slurry to pass through is formed between the outer wall of the secondary dispersion teeth 511 and the inner wall of the secondary stator seat 510. The structure of the secondary stator 51 is the same as that of the primary stator 40. The secondary stator seat 510 is arranged in a circular ring shape, and the secondary dispersion teeth 511 are evenly fixed on the inner circle of the secondary stator seat 510. The radial clearance between the secondary stator 51 and the secondary rotor 52 is small, so the slurry enters the matching clearance between the secondary rotor 52 and the secondary stator 51 and impacts the outer wall of the secondary stator 51 at a very high speed from the edge of the secondary rotor 52. Under the action of centrifugal force, the slurry is successively thrown out from the tooth grooves between the secondary through hole 12520 and the secondary dispersion teeth 511, enters the secondary channel 53, and is discharged from the discharge port 8. Due to the high tangential speed generated by the high-speed rotation of the secondary rotor 52 and the strong kinetic energy brought by the high-frequency mechanical effect, the material is subjected to strong mechanical and hydraulic shearing, centrifugal extrusion, liquid layer friction, impact tearing and other comprehensive effects in the narrow gap between the secondary stator 51 and the secondary rotor 52, and is instantly sheared and dispersed. After two-stage high-frequency reciprocating cycles, a mixed product is finally obtained.

[0032] The power assembly 2 includes: a motor 20 installed on the frame 1, a driving pulley 21 coaxially connected to the output shaft of the motor 20, and a driven pulley 23 connected to the driving pulley 21 through a synchronous belt 22. The driven pulley 23 is sleeved and installed on the rotating shaft 3. The motor 20 drives the driving pulley 21 to rotate, and the synchronous belt 22 drives the driven pulley 23 to rotate, thereby driving the rotating shaft 3 to rotate, which can drive the primary rotor 41 and the secondary rotor 52 to rotate at high speed, thereby achieving dispersion and mixing of the slurry.

[0033] In order to make the rotating shaft 3 rotate better, the rotating shaft 3 is connected to the frame 1 through a bearing, and the rotating shaft 3 and the frame 1 are rotatably connected through a bearing seat 9. The upper and lower ends of the bearing seat 9 are fixed with bearing end covers 10 for fixing the bearings. The top end of the bearing seat 9 is fixed on the lower surface of the frame 1, and the bottom end is fixed on the upper surface of the machine seal seat 7.

[0034] In order to achieve better sealing, O-rings are provided between the mechanical seal seat 7 and the secondary stator seat 510 , between the secondary stator seat 510 and the primary stator seat 400 , and between the primary stator seat 400 and the lower end cover 6 .

[0035] A cooling water channel 11 is provided on both the primary stator seat 400 and the secondary stator seat 510. The cooling water channel 11 on the primary stator seat 400 is interconnected with the cooling water channel 11 on the secondary stator seat 510 through a plurality of through holes 12. A cooling water inlet is provided on the primary stator seat 400, and a cooling water outlet is provided on the secondary stator seat 510. In this embodiment, the cooling water channel 11 on the primary stator seat 400 is interconnected with the cooling water channel 11 on the secondary stator seat 510 through two through holes 12, and a line connecting the centers of the two through holes 12 passes through the center of the rotating shaft 3.

[0036] The slurry will generate a lot of heat under the action of high-speed shear mixing and friction. Excessive heat will destroy the molecular structure of the material. Therefore, cooling water needs to be introduced into the cooling water channel 11 to cool the material.

[0037] A proximity switch 13 is fixed on the frame 1, a speed measuring disc 14 is fixed on the top of the rotating shaft 3, and a plurality of sensing elements 15 cooperating with the proximity switch 13 are equidistantly mounted on the speed measuring disc 14, so as to facilitate detection of the linear speed of the rotor and the secondary rotor, and to facilitate detection of the linear speed of the rotating shaft. In this embodiment, the maximum linear speed of the rotor and the secondary rotor is 30 m / s.

[0038] For ease of installation, the first-stage stator 40 and the first-stage stator seat 400 can be integrally formed, the second-stage stator 51 and the second-stage stator seat 510 can be integrally formed, and the arc cutter 411 and the first-stage rotor seat 410 can be integrally formed.

[0039] It should be understood that the specific embodiments described above are only used to explain the present invention, and are not used to limit the present invention. Obvious changes or modifications derived from the spirit of the present invention are still within the scope of protection of the present invention.
