Technical field
The present invention relates to high viscosity mixing equipment and technology, more particularly to a kind of twisted blade double helix ribbon agitator.
Background technology
Liquid mixing is process industry inalienable part, and is come for the blender as mixing heavy viscous material
Say, raw material can be largely moved to the other end by it from one end of container.
Double helix ribbon-type blender is a kind of blender for being used in industry mix heavy viscous material and liquid.In double helix
Screw rod or band in, two hurricane bands are attached to central shaft, allow raw material to move to another side from a direction in rotary course
To making raw material be well mixed in a short time.In common helical mixer, band is connected to frequently by bar or flat blade
Central shaft, but this can reduce overall mixing efficiency.In addition, when blade is rotated with fixed angle, sophisticated speed is higher than root,
Because compared with the part of root of blade, in time per unit, tip portion need to cover more distances.The change of this speed
Cause the span skewness of blade.It is uneven that this feature does not only result in VELOCITY DISTRIBUTION, and blade can be applied bigger
Stress, maximum in vane tip, root is minimum.This nonuniform speed distribution through blade span even can cause flowing
Internal mixing is uneven, and applies more high stresses in blade span.

Axle axis direction is equidistantly provided with stirring vane, and the stirring vane root is connected with the main shaft, the stirring vane end with
First hurricane band or the second spiral band connection, the stirring vane are strip and distorted around own axes, the paddle
The torsion angle of piece root be more than the stirring vane end reverse angle, the incline direction of the stirring vane with connection its described
The first hurricane band or the second hurricane band incline direction it is consistent.
Stirring vane is strip and distorted around own axes that the torsion angle of the stirring vane root is more than in above-mentioned design
Angle is reversed in the stirring vane end, and gradually changing for this angle across blade span contributes to being uniformly distributed for speed,
So that vane efficiency maximizes and reduces the stress across blade span, mixing is more uniform, improves making for integral device
Use the life-span.
As the further improvement of the design, the every main shaft is provided with 10 stirring vanes, per two panels stirring vane
For one group, two stirring vanes in every group of stirring vane are made 360 ° of annular arrays around the main shaft and are uniformly distributed, in every group
A piece of stirring vane and the first spiral band connection, another stirring vane and the second spiral band connection, stress are put down in every group
Weighing apparatus, moment of torsion are cancelled out each other.
As the further improvement of the design, first hurricane band and the second hurricane band and coupled paddle
Piece is integrated, and only hurricane band does not provide stable support, and all stirring vanes can all regard a single agitator as.
As the further improvement of the design, the inclination angle of the stirring vane end and connected first hurricane band or
The inclination angle of the junction of second hurricane band is identical, transitions smooth, prevents fluid from being accumulated in junction, stirs.
As the further improvement of the design, the stirring vane width is less than the 1/8 of stirring vane rotating diameter, is easy to
Stirring is to expect the flowing of body.
As the further improvement of the design, first hurricane band and the second hurricane band axially have constant spiral shell along main shaft
Away from and width, first hurricane band and the second spiral bandwidth are identical with stirring vane width, are easy to the uniform of stirring vane
Stress and stirring vane seamlessly transit with the first hurricane band and the second hurricane band.
The beneficial effects of the invention are as follows：Stirring vane is strip and distorted around own axes, the paddle in the present invention
The torsion angle of piece root is more than the stirring vane end and reverses angle, and gradually changing for this angle across blade span helps
In being uniformly distributed for speed, so that vane efficiency maximizes and reduces the stress across blade span, mixing is more uniform,
Improve the service life of integral device.
