Description
The present invention relates to a kind of agitator, relate in particular to the high bowl-type efficient mixer of a kind of mixing efficiency.
Agitator generally is installed in the mixer, finishes chemical reactions such as dispersion, emulsification, mixing, dissolving, absorption, extraction with stirred vessel, and diabatic process, so mixer is widely used in industries such as chemical industry, daily-use chemical industry, food.
In mixer, the running by agitator makes the liquid flow in the container.Pattern according to liquid flow can be divided into three kinds of main types: one, and tangential flow problem, described tangential flow problem are meant that the direction that liquid in container flows is parallel to the blade direction of motion; Its two, radius flow pattern, described radius flow pattern are because action of centrifugal force, liquid forms the liquid stream of radial pattern by blade discharge outward; Its three, the axial flow pattern, described axial flow pattern is meant that liquid flow direction is parallel to turning cylinder.
In the type of three kinds of above-mentioned liquid flows, wherein axial flow is a kind of more important and effective flow problem, and it is the very high a kind of preferred flow pattern of mixing efficiency in cosmetics and the articles for washing industry.But in actual production process, the liquid flow pattern of being produced in any agitator, all be to wish it is the combination of three kinds of flow problems, because under different situations, the contribution that various flow problem is done is all different, in any mixing apparatus, even the flow pattern of in any agitator, being produced, all be to wish it is the combination of three kinds of flow problems, and in any mixing apparatus, the size and the shape of formed liquid flow pattern and mixer when mixing, and the speed of used blade and hybrid device, shape and type have confidential relation.
Prior art agitator (seeing also shown in Figure 3) is made up of shaft 1 and the paddle 2 that is positioned on the shaft 1 usually, agitator rotates through driven by motor in mixer 3, paddle 2 just will originally be positioned under the powder belt on mixer 3 tops, mix with unclassified stores, form uniform liquid, but in actual production process, still exist and stir uneven phenomenon, its reason is:
One. liquid does not produce axial flow.
Because its paddle 2 of prior art agitator is slurry formula structures, so this paddle 2 makes flowing of liquid only produce flowing of eddy current form along with the rotation of motor, do not produce axial flow, so that the materials in the mixer 3 stir is inhomogeneous;
Two. the installation position of agitator is difficult to follow.
Because its paddle 2 of prior art agitator is slurry formula structures, it is difficult in mixer 3 to form mix completely and stirs, therefore when paddle 2 during in mixer 3 internal upper part positions, for high viscosity, high specific gravity material or liquid, can only produce laminar flow, mix difficulty; And therefore when paddle 2 when mixer 3 low insides are put, for proportion lighter powder or cotton-shaped buoyant, this agitator is difficult to and will floats under the buoyant or liquid band on liquid upper strata, mix and stirring, so it can not finish real mixing and stirring work.

In above-mentioned bowl-type efficient stirrer, wherein, described paddle is conical structure, and the scope of the angle α between paddle lobe and the shaft axle sleeve sidewall is between 45 °～75 °.
In above-mentioned bowl-type efficient stirrer, wherein, the best angle of described angle α between paddle lobe and shaft axle sleeve sidewall is 60 ° of positions.
In above-mentioned bowl-type efficient stirrer, wherein, described liquid flow hole is the manhole with a certain size.
In above-mentioned bowl-type efficient stirrer, wherein, one paddle respectively is set the appropriate position respectively up and down at described shaft.
In above-mentioned bowl-type efficient stirrer, wherein, described two paddles can be provided with tapered and make progress and downward version respectively.
Bowl-type efficient stirrer of the present invention makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect:
One. liquid can produce axial flow at container.
The present invention is because blade is cone shape, it is dark outer shallow in the height of paddle lobe is, when blade rotates with shaft, liquid in container outwards and upwards throws away because of action of centrifugal force, and form parital vacuum in the container bottom, thereby the liquid flow hole of liquid from disk sucked downwards, liquid stream is also done axially-movable thereupon, and make liquid stream from top to bottom flow to container inner wall and upwards reflux again, form axial flow completely.
Two. can settle the position of agitator according to special circumstances.
The present invention is because if when making blade rightabout and install, can form antipodal liquid flow pattern formula, therefore can conical surface paddle in opposite directions be set in the shaft appropriate location according to different situations, thereby the container of specific condition is mixed and stirring fully with material.
