The specific embodiment
Below in conjunction with accompanying drawing, the utility model is elaborated.
Fig. 1 is the structural representation of the utility model embodiment, comprise cylindrical shell 1, at the top of cylindrical shell 1, be provided with permanent magnet direct driving motor 2 and charging aperture 7, permanent magnet direct driving motor 2 is directly connected with the rotating shaft of paddle, there is fixed support 6 that permanent magnet direct driving motor 2 is fixed on cylindrical shell 1 simultaneously, the control end of motor is connected with variable frequency regulating speed control machine, and charging aperture 7 is for being connected with upstream equipment.Directly connected permanent magnet direct driving motor 2 improves the torque of agitator greatly, has reduced energy consumption and maintenance cost simultaneously.
Fluid foods, after charging aperture 7 enters cylindrical shell 1, flows downward along axle center under the shearing force of paddle and stirring action, then along the pod apertures in the deflector of inner barrel, along sidewall, upwards flows.
Segment fluid flow material enters upstream device from discharging opening 8, and the effect of unclassified stores anti-splash guard 5 at top is returned to cylindrical shell 1 axle center continuation stirring and sized mixing.
3 groups of stirring vanes are installed in the paddle rotating shaft of the present embodiment, the horizontal length of every stirring vane is 1/2 of cylindrical shell inside radius, the total of 3 stirring vanes is vertically highly 35% of cylindrical shell total height, according to concrete service condition, 2-5 group stirring vane also can be installed, 1/5～2/3 of the desirable cylindrical shell inside radius of stirring vane horizontal length, the total of stirring vane is vertically highly 30%～60% of cylindrical shell total height.On each stirring vane in paddle, be provided with the stirring vane pod apertures 31 of some, the present embodiment is provided with two stirring vane pod apertures, and any amount in 1-4 also can be set as required.Stirring vane pod apertures is arranged at stirring vane and by outer, is worked 1/5～1/3 place that accounts for stirring vane horizontal length, and the present embodiment is arranged on 1/5 place.In order to guarantee that stirring vane pod apertures plays the effect of the better shearing force of generation, the gross area of stirring vane pod apertures accounts for 5%～50% of the stirring vane gross area simultaneously, and the present embodiment has adopted 30%.
The present embodiment is provided with 2 groups of deflectors on cylinder lateral wall, deflector and stirring vane shift to install, every group of deflector is arranged at the middle of two groups of stirring vane vertical spacings, the horizontal length of each deflector is 2/3 of cylindrical shell inside radius, according to concrete service condition, 1-4 group stirring vane also can be installed, 1/5～2/3 of the desirable cylindrical shell inside radius of stirring vane horizontal length.At deflector, near cylindrical shell 1 part, be provided with bracing frame 42.The paddle of the deflector of many group horizontal positioned and the vertical placement of many groups improves the shearing force and the intensity that stir greatly.
Fig. 2 be the cylindrical shell 1 of the present embodiment along the top view structure between AA '-BB ' cross section, this figure be take "+" font paddle and deflector space and is illustrated as example.The inner side of cylindrical shell 1 is evenly installed with 4 deflectors, fixing with cylindrical shell 1 by deflector fittable slackening device 42, in each deflector, be uniform-distribution with a plurality of deflector pod apertures 41, in order to reach preferably shearing force effect, the number of each deflector baffle upper plate pod apertures is 10～200, and the gross area of the deflector pod apertures simultaneously having on each deflector accounts for 30%～80% of the deflector gross area.Cylindrical shell 1 center and deflector space corresponding "+" font paddle 3, be provided with the pod apertures 31 in paddle in the stirring vane outer of paddle 3, reaches the shearing force that further adds strong mixing by many groups pod apertures.The large torque that in whipping process, permanent magnet direct driving motor brings makes fluid produce the stirring intensity stirring on blade tangential, fluid will have very large tangential and radially outer momentum, after contacting with agitator cylindrical shell, a momentum axially making progress along barrel will be produced, arranging of deflector and pod apertures makes this strong friction above axial and pod apertures edge of fluid on the one hand, improved the shear action of convection cell, on deflector, non-bore portion has increased the disturbance of cylindrical shell inner fluid, the stirring that has improved fluid on the other hand.
Fig. 3 is the example with the deflector of different pod apertures structures, deflector pod apertures 41 and stirring vane pod apertures all can be arranged to various shapes according to actual conditions, accomplish both to guarantee that fluid foods receives enough shearing forces, can guarantee the mobility that fluid foods is suitable again.
