| Firstly, the stability of the suspension and the fluidity character of the non-homogenizing liquid have been analyzed and the essence of the mechanism has been opened out. On the base of theory of hydrodynamics and mechanics of materials, the load situation of high-shearing homogenizer and the hydro-motion in high-shearing homogenizer have been analyzed comprehensively. The mechanism of laminar flows in trough, turbulent flows in trough, convolute laminar flows and convolute turbulent flows were educed. The force and restriction of high-shearing homogenizer was determined. These provided theoretic basis and design reference for new design of high-shearing homogenizer.Then, on the base of the theory of homogenizer and patents in existence, a new type of high-shearing homogenizer was designed. The troughs of stator were radial. The toughs of rotor were at tangent of basis circle. A solid model of rotor, key component, was built in PRO/E. Stress, distortion and vibration was imitated with ANSYS, in order to insure intension, to prevent impact stator owing to high-speed wheel, to avoid resonance owing to the adjacence of natural frequency and exciting frequency. These provided reference for the design and research key structure of high-shearing homogenizer.Last, the flow fields of the key parts of the new-type high-shearing homogenizer, the clearance between stator and rotor, the troughs of stator and the troughs of rotor, were analyzed in theory. The field of whole flow field and tangential velocity between stator and rotor were imitated based on FLUENT. The analysis in theory was replenished.The design and imitation of dynamics performance and flow field of new-type high-shearing homogenizer would establish a research basis for high-shearing homogenizer. |
