  • ABSTRACT A device for continuous! mixin or reactin li uids 30 F P v y g E q I l J 27:52 only Data J has a cylinder with a plurality of spaced radial liquid inune apan 4537383 lets'intermediate its ends for sequentially adding liquid and an outlet. An agitator having two or more shafts $3.8].
  • the mixture of the liquids must be completely uniform in composition until the next added solution is applied. This is because the subsequent mixture and reaction of the liquids become irregular with the result that the effect of the solution is reduced or detrimental product extremely deteriorates the quality ofthe mixture v ,3.
  • the staying time of the liquid in the device must not be extended. The extension of the staying time of the liquids in the device producesthe extension of the performance distribution of the composition of theliquids passing through the device.
  • the former three types may provide uniform density quickly from the mixed liquids and may also mix the solution according to a predeterminedorder, but are difficult due to the increase in the staying time of the liquids in the mixer and reactor and the parts-are also .difficult to partiallyclean. 7
  • a device for continuously mixing or reacting liquids which comprises a cylinder' having a plurality of liquid inlets and an outlet for mixing or reacting liquids, an agitatorhaving two or more shafts disposed parallel with the axis of said cylinder and also having a plurality of blades fixed on the respective shafts for extremely restricting the mixture and agitation of the liquids in the' axial direction but freely flowing the liquids radially.
  • FIG. I is a longitudinal sectional view of one embodiment of the device constructed in accordance with the present invention.
  • FIG. 2 is a sectional viewof the device taken along the line 2-2 in FIG. 1; j
  • FIG. 3 is a view of an agitating blade used in the device formed according to the present invention.
  • FIG. 4 is a graph showing the extension of the staying time of one experiment using the device of this invention.
  • FIG. 1,' shows one embodiment of the device constructed according to the present invention.
  • Reference numeral 1 illustrates a cylindrical body for I mixing or reacting liquids, 2 a jacket for holding liquid in the body at a predetermined temperature, 3 an axial inlet for a first liquid to be mixed or reacted liquid, shafts 4, 6 and 7 for agitating blades 8 and 9 connected to drive means (not shown) such as an electric motor through mechanical seals or bearings fixed to the upper and lower walls of the cylinder.
  • the agitating blades 8 and 9 are thin planar disc shapefor flowing the liquids radially.
  • 10 to 14 show radially disposed adding inlets provided at the side wall of the cylinder for introducing respectively, other liquids to be mixed with or reacted to the first liquid in order into the cylinder
  • 15 is an outletfor discharging mixed' or reactedliquid out of the rection perpendicular to the axis of the cylinder with sufficiently stirring, at the same time, the first liquid is carried to the outlet 15 along the axis of the cylinder as a wholenwhileother liquids introduced into the cylaction of agitating blades provided near respective inlets to 14 and mix with the first liquid in turn.
  • the inner diameter of the cylinder may be selected depending upon the type of reaction, reacting time, treating capacity, etc., and also depending upon the number of agitating shafts and the size of the agitating blades.
  • the number of shafts of the agitator must be at least two or more, and may preferably be four.
  • the shape of the agitating blades must be, for example, of circular disc shape as shown in FIGS.
  • the thickness of the blades may preferably be of l to 5mm
  • the diameter of the blades may preferably be one-fourth to one-half the inner diameter of the cylinder.
  • the distance between the agitating blades on the same shaft may preferably be 20 to 60 mm.
  • the number of revolutions of the agitating blades may preferably be 400 to 500 rpm, and if it is excessively low, the mixing becomes worse, while if it is excessively high, the staying time of the liquids is extended due to thereverse mixing.
  • the rotating direction of the blades may be in the same direction, or may partially be in the reverse direction.
  • the distance and number of the radial inlets mounted at the wall of the cylinder maybe determined depending upon the number of the solution or liquids and adding capacity and mixing time. There exist some upward and downward flows near the inlets for the liquids but there exist mainly radial flows, and if turbine blades superior in spattering force are provided, the mixing of the liquid,
