Description

Two-way agitator with second grade rotary mechanism

Technical Field

The utility model belongs to the technical field of stirring, and relates to a bidirectional stirrer with a secondary rotating mechanism.

Background

In the production and life processes of chemical engineering, pharmacy, bioengineering, scientific experiments, catering and the like, a stirrer is often needed to realize the uniform distribution of substances with different characteristics in a container. Generally, depending on the structure of the agitator, the agitator is classified into a radial agitator, an axial agitator and a hybrid agitator, but generally has only a single rotating shaft. In order to achieve a sufficient mixing of the working medium in the stirrer, the volume swept over by the moving parts of the stirrer is limited. For high viscosity materials, the material tends to stick to the agitator, i.e., the wall of the container, so that the material to be agitated is divided into a portion according to the rotation of the agitator and a non-rotating portion not swept by the agitator during agitation. There is no relative movement between the two parts, and the two parts exchange materials only on the surface, so that the efficiency of stirring and mixing becomes low.

The purpose of the utility model can be realized by the following technical scheme:

a bidirectional stirrer with a secondary rotating mechanism comprises a primary stirring shaft and at least 2 secondary stirring mechanisms which are circumferentially arranged on the primary stirring shaft;

the second grade rabbling mechanism including rotate locate the epaxial second grade (mixing) shaft of one-level (mixing) and a plurality of epaxial bending rotating blade of second grade (mixing) of laying along circumference, a plurality of bending rotating blade's the same direction of buckling just all set up along the circumference of second grade (mixing) shaft.

As a preferable technical scheme, the height of the primary stirring shaft is adjustable, so that the effective stirring range of the secondary stirring mechanism can be adjusted according to actual conditions.

Furthermore, the end part of the first-stage stirring shaft is fixedly provided with a connector, a plurality of rotating bearings are arranged in the connector, and one end of the second-stage stirring shaft is embedded in the corresponding rotating bearing.

Furthermore, the bending rotating blade comprises a stirring plate arranged on the second-stage stirring shaft and a downstream rotating plate arranged at the outer end of the stirring plate and inclined with the stirring plate.

Further, the stirring plate and the downstream rotating plate are both rectangular plates.

Furthermore, the stirring plate and the downstream rotating plate are designed in an anti-symmetric manner to ensure that the incoming flow resistance on the blade is unequal, so that the rotating moment of the blade is formed.

Further, the bending rotating blades are fixed on the second-stage stirring shaft through bolts, are connected through bolts so as to be convenient for later-stage replacement and maintenance, and are used for stirring blades of different types aiming at different stirring working media.

Compared with the prior art, the utility model has the following characteristics:

1) according to the utility model, the second-stage stirring mechanism capable of freely rotating is vertically arranged at the bottom end of the first-stage stirring shaft, and the blade with the bending structure is used as the stirring blade of the second-stage stirring mechanism, so that when the second-stage stirring mechanism is driven by the first-stage stirring shaft and rotates in the circumferential direction in the stirrer, the resistance borne by the upper blade and the lower blade is unequal due to the bending structure, the second-stage stirring mechanism can spontaneously generate rotating stirring without a motor, the cost of the device can be effectively reduced on the basis of ensuring the stirring effect, and complex mechanisms such as gears and the like are prevented from being arranged in the stirred material, so that the stability of the product is improved;

2) the whole rotation direction of the secondary stirring mechanism is vertical to the rotation direction of the blades, so that multidirectional stirring and mixing in the horizontal direction and the vertical direction can be realized, and the swept volume of the secondary rotating blades is far higher than that of a primary stirrer due to the coupling effect of the primary rotation direction and the secondary rotation direction, so that the stirring and mixing effect of the stirrer can be improved, the stirring efficiency can be improved, and the stirring time can be shortened;

3) the utility model can effectively avoid the final stirring effect from being damaged due to adhesion between the super-sticky substances in the stirrer and the stirrer, thereby ensuring the product quality of the stirring working medium.

container

6, and 2 secondary stirring mechanisms arranged on the primary stirring shaft 1 relatively. This second grade rabbling mechanism includes that perpendicular rotation locates the second grade (mixing) shaft 2 on the one-level (mixing) shaft 1 to and 4 arrange the turning vane 3 of buckling on the second grade (mixing) shaft 2 along the equal contained angle of circumference.
