2results about How to "Increase shear rate" patented technology

The utility model relates to the technical field of stirring equipment, concretely to a kind of anti-condensation stirring equipment for glass cement production, including bottom plate and the moving plate being set on the top of bottom plate, the outside of bottom plate is provided with the moving assembly of making moving plate go up and down linearly moves. The utility model can make the reciprocating of stirring shaft up and down, to realize the stirring of vertical direction, while stirring shaft is in the process of rotating and up and down linear reciprocating motion, stirring blade is constantly in the process of expansion and contraction motion, this reciprocating expansion and contraction motion is superimposed on the rotation of stirring shaft, can increase the shear rate and turbulence intensity of fluid;Periodic expansion and contraction changes flow field structure, possibly breaks laminar boundary layer, promotes microcosmic mixing, expansion and contraction motion generates unsteady flow, triggers secondary flow or vortex, expands stirring action range, reduces mixing dead zone, to improve stirring efficiency, also improve anti-condensation effect.

This invention relates to the field of lithium battery cathode material production technology, and discloses a washing system and washing method. The washing system includes a washing device, which comprises a washing drum and a stirring assembly. The washing drum has a stirring chamber inside, and is equipped with a material inlet and a material outlet communicating with the stirring chamber. The material inlet continuously introduces the material to be washed and the washing solution, while the material outlet continuously discharges the mixture of washed material and washing solution. The stirring assembly includes two spiral shafts rotatably disposed within the washing drum, with their spiral edges staggered and rotating in the same direction. Based on the washing system provided by this invention, the washing process of the material to be washed can be ensured to be continuous, reducing interruptions and improving production efficiency; at the same time, it ensures the uniformity of the material to be washed, avoiding over-washing or under-washing, and guaranteeing product consistency.
