Abstract

The utility model discloses a dislocated blade stirrer, comprising a stirring shaft, a hub and six blades, wherein the hub is arranged on the stirring shaft; the six blades are evenly distributed in the circumference direction; and the six blades are intersected and staggered up and down. The dislocated blade stirrer has the beneficial effects that the improved stirrer is suitable for stirring high-viscosity liquid, can enhance the entire liquidity of fluid inside a stirring tank no matter whether the fluid is newtonian fluid or non-newtonian fluid, reduces or even completely removes a mixed isolation region, improves the stirring effect, has the effect of saving energy at the same time, can shorten the mixing time, and improves the mixing efficiency. A larger low-pressure area can be generated when the dislocated blade stirrer is applied to pseudoplastic fluid agitation; the shearing rate generated at different heights is obviously higher than that of the standard flat blade stirrer; and the cave effect can be removed. In addition, the improvement effect of blade dislocation on a flow field is related with the rotating speed of the stirrer; and the higher the rotating speed of the stirrer is, the better the improvement effect is within the permitted range.

Described blade is straight blades, and straight blades is arranged on disk, and this disk is installed and fixes with wheel hub is concentric.
When described straight blades and integrated disc portions dislocation, on straight blades, fluting is affixed with disk; When described straight blades and disk misplaced fully, the upper surface of straight blades or lower surface and disk were affixed, and arranged stiffener between straight blades and disk.
When blade is straight blades and itself and disk when misplacing fully, the interior diameter of wheel hub is 30mm, and overall diameter is 50mm, is highly 40mm.It is the 8.5mm place that disk is arranged on apart from the wheel hub lower surface, and the thickness of disk is 3mm, and the disk overall diameter is 100, and interior diameter is 50mm.The thickness of straight blades is 3mm, and length is 38mm, is highly 30mm.The height of stiffener is 10mm, and thickness is 3mm, and the distance of stiffener medial surface anomaly prismatic blade inner face is 5mm.Wheel hub adopts screw to be connected with shaft, and screw is the M6 hole, the centre-to-centre spacing wheel hub upper end 8mm in hole.Stirrer diameter after installation is 150mm.
Described blade is camber blades, and camber blades are arranged on wheel hub.
Described camber blades misplace fully, and the upper and lower end face of adjacent two camber blades is concordant.
Described wheel hub and shaft adopt screw or key to be connected, and during less than 400mm, agitator is connected with shaft by screw when stirrer diameter; During greater than 400mm, adopt the key syndeton between agitator and shaft.
When blade is camber blades and adjacent flex blade when misplacing fully, the interior diameter of wheel hub is 30mm, and overall diameter is 55mm, height 85mm.The height of camber blades is 30mm, and thickness is 6mm, and the radian of camber blades is 30 °, and the upper and lower end face of adjacent two camber blades flushes, and the lower surface of lower floor's camber blades is apart from wheel hub lower surface 5mm.Wheel hub adopts two screws to be connected with shaft, and screw is the M6 hole, and the centre-to-centre spacing wheel hub upper and lower side in hole is 8mm.Stirrer diameter after installation is 150mm.
The application replaces the concordant blade construction of standard agitator with the dislocation blade construction, the principle of improving institute's foundation is: in the situation of blade flush arrangement, when stirring high viscosity fluid, in tank diameter, can there be a pair of mixing isolated area in the blade upper and lower, the blade of blade dislocation cloth postpone diverse location is the prolonged agitation fluid ceaselessly, produce the flow field that change aperiodic in tank diameter, reach the purpose of eliminating isolated area, inducing fluid chaotic mixing.
The beneficial effects of the utility model are: the agitator after improvement is applicable to the stirring of high viscosity liquid, no matter for Newton type fluid, or non-Newtonian fluid, can strengthen the overall flow of tank diameter inner fluid, reduce to eliminate even fully the mixing isolated area, improve mixing effect, shorten incorporation time.When being applied to the pseudoplastic fluid stirring, can produce larger area of low pressure, the shear rate that produces on differing heights can be eliminated the cave effect apparently higher than the concordant blade mixer of standard.In addition, blade dislocation stream field to improve effect relevant with the rotating speed of agitator, in allowed limits, the rotating speed of agitator is larger, improves effect better.
