Description

Two helical ribbon agitator

Technical field

The utility model relates to chemical plant installations field, is specifically related to a kind of two helical ribbon agitator.

Background technology

Make liquid, gaseous media forced convection mixed uniformly device. The type of agitator, size and rotating speed, have impact to the distribution of power of agitator between bulk flow and turbulent flow are pulsed. In general, the power division of turbine type agitator is favourable to turbulent flow pulsation, and rotary propeller type agitator is favourable to bulk flow.

But for sticky thick liquid, turbine type agitator and propeller stirrer are applicable to the rarer liquid of viscosity usually, it is generally viscosity and it is no more than 25mPa s, and for the thicker liquid of viscosity, often then use rotary propeller type, but it is only play the simple shearing force that produces to be stirred, therefore, the region stirred is only limitted to the liquid being positioned at around agitating vane, and due to the mobility of thick liquid poor, region away from agitating vane then fails to contact with agitating vane and cause and be not sheared stirring, therefore, cause the weak effect of stirring, uneven phenomenon.

Practical novel content

The technical problems to be solved in the utility model is to provide a kind of stirring evenly and two helical ribbon agitators that mixing effect is good.

In order to solve the problems of the technologies described above, the utility model provides following technical scheme: two helical ribbon agitator, comprise housing, the stir shaft of hollow and the agitating vane of hollow, agitating vane comprises counterclockwise ribbon and clockwise ribbon, clockwise ribbon around stir shaft by the setting that turns clockwise to top bottom it, counterclockwise ribbon is rotated counterclockwise setting by bottom it to top around stir shaft, and the bottom of ribbon and the bottom of clockwise ribbon connect counterclockwise, stir shaft is through the junction bottom clockwise ribbon and counterclockwise ribbon, first agitating vane is identical with the rotation pitch of the 2nd agitating vane, counterclockwise ribbon and clockwise ribbon are equipped with multiple through hole.

Adopt the double ribbon agitator of technical solutions of the utility model, counterclockwise ribbon and clockwise ribbon form two ribbon, thus during stir shaft rotation stirring, solution is promoted by outside duplex from bottom to top, solution in the form of a ring waviness rotate and collect in the middle part of stir shaft, the solution that will collect and is stirred from upper downward volution transmission in middle part, reaction soln is made to be able to comprehensive seethe up and down in container, different substances is able to abundant fusion, and reaction is more thorough, more completely. The stir shaft of hollow is when reinforced, material can be added from the upper end of stir shaft, avoid materials from spattering, the agitating vane of hollow make solution from downwards, from the bottom to top spiral transmit process in, not only can transmit at counterclockwise ribbon and clockwise ribbon outside, also from the empty internal transmission of counterclockwise ribbon and clockwise ribbon, thus the stirring intensity of solution can be strengthened; Moreover, the through hole on counterclockwise ribbon and clockwise ribbon, in the process transmitted, can transmit straight down from through hole, and mixing effect is better.

Principle of work of the present utility model is: be added in housing by solution from the upper end of stir shaft, then stir shaft is opened, stir shaft drives counterclockwise ribbon and clockwise ribbon to rotate, material is promoted from the bottom to top, then after promoting from the inside of counterclockwise ribbon and clockwise ribbon and outside, more from top to bottom transmit, in the process of transmission simultaneously, solution can drop from through hole, so that solution stirs evenly comprehensively. Comparing the agitator of existing rotary propeller type, stirring of the present utility model is even and mixing effect good.

Further, described counterclockwise ribbon and clockwise ribbon are equipped with stiffening web. Stiffening web not only can play the effect of shear agitation, and can play the effect strengthening the first agitating vane and the 2nd agitating vane.

Further, described stiffening web is steel plate, with counterclockwise ribbon and the T-shaped setting of clockwise ribbon. Steel plate is easy to process and shearing force strong, and mixing effect is good.

Further, the diameter of described through hole is increased to outside near the side of stir shaft successively by counterclockwise ribbon, clockwise ribbon. The outside making material as far as possible flow to counterclockwise ribbon and clockwise ribbon is from top to bottom transmitted, thus expands the area of stirring, the better effects if of stirring.

Further, described housing is cylinder shape, and internal diameter is 1800mm.

Further, described counterclockwise ribbon and the pitch of clockwise ribbon are 1200mm, and width is 100mm, and thickness is 12mm. It is applicable to material stirring and reaction that material viscosity is greater than 400mPa s.

Further, the thickness of described stiffening web is 12mm.

Accompanying drawing explanation

Fig. 1 is the cross-sectional schematic that the two helical ribbon agitator of the utility model executes example.

In figure: housing 1, stir shaft 2, counterclockwise ribbon 3, clockwise ribbon 4, stiffening web 5, through hole 6.

Embodiment

As shown in Figure 1, the two helical ribbon agitator of the utility model, comprise housing 1, the stir shaft 2 of hollow and the agitating vane of hollow, housing 1 is in cylinder shape, and internal diameter is 1800mm, agitating vane comprises counterclockwise ribbon 3 and clockwise ribbon 4, the pitch of counterclockwise ribbon 3 and clockwise ribbon 4 is 1200mm, width is 100mm, thickness is 12mm, counterclockwise ribbon 3 and clockwise ribbon 4 are equipped with stiffening web 5, stiffening web 5 is steel plate, the thickness of stiffening web 5 is 12mm, with counterclockwise ribbon 3 and the T-shaped setting of clockwise ribbon 4, clockwise ribbon 4 around stir shaft 2 by the setting that turns clockwise to top bottom it, counterclockwise ribbon 3 is rotated counterclockwise setting by bottom it to top around stir shaft 2, and the bottom of ribbon 3 and the bottom of clockwise ribbon 4 connect counterclockwise, stir shaft 2 is through the junction bottom clockwise ribbon 4 and counterclockwise ribbon 3, first agitating vane is identical with the rotation pitch of the 2nd agitating vane, counterclockwise ribbon 3 and clockwise ribbon 4 are equipped with multiple through hole 6, the diameter of through hole 6 is by counterclockwise ribbon 3, clockwise ribbon 4 increases to outside successively near the side of stir shaft 2.

In specific implementation process, material is added in housing 1 from the upper end of stir shaft 2, then stir shaft 2 is started, stir shaft 2 rotarily drives counterclockwise ribbon 3 and clockwise ribbon 4 rotates, material is in the rotary course of counterclockwise ribbon 3 and clockwise ribbon 4, the backward upper lifting in inner side is flowed to gradually by the outside of the outside of ribbon and inner outside, in the process promoted, stiffening web 5 not only plays the effect of reinforcement, counterclockwise ribbon 3 and clockwise ribbon 4 is avoided to be subject to moment of torsion and be out of shape in the process rotated, on the other hand, also material can be produced shearing force, add strong mixing, a solution part vertically flows down from through hole 6 again, another part is then by the lateral current downflow of counterclockwise ribbon 3 and clockwise ribbon 4, thus stir evenly comprehensively.

For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also making some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability that the utility model is implemented.
