Abstract
The invention discloses a stirrer driving rod. The driving rod is composed of an upper driving rod and a lower driving rod, a coupling portion connects the upper driving rod with the lower driving rod and transmits torque, the coupling portion changes the turning direction of the lower driving rod to be opposite to the turning direction of the upper driving rod, and the lower ends of the upper driving rod and the lower driving rod are respectively provided with an upper stirring paddle and a lower stirring paddle. The opposite direction stirring of the upper and lower stirring paddles enhances the shearing force, effectively alleviates deposition of solid particles caused by single-blade straight stick stirring circular flow on the wall of a reaction tank, reduces the dead zones in the reaction tank, and benefits full implementation of mixing, dispersion, heat transfer and reaction processes.
Description
Patent application of the present invention is the divisional application of invention and created name " a kind of agitator ", and the applying date of original application is on November 7th, 2013, and application number is 2013105482824.
Technical field
The present invention relates to the agitating device of Chemical Manufacture industry, is specifically a kind of agitator.
Background technology
At present, the agitator being applied to Chemical Manufacture industry is different, wherein single leaf straight rod agitator because simple structure, production cost be low, easy to maintenance etc., be used widely by feature, but there is several shortcoming in single leaf straight rod agitator in production application: one, shearing force is little, single leaf stirs because shearing force is little, the hoop stream effect produced is obvious, and longitudinally stream is relative with slipstream weakens.This " turning round and round " phenomenon easily causes reaction pool wall deposits materials, causes raw material to lose.Dead band simultaneously in pond can affect reaction effect and product quality greatly; Two, react insufficient, the scope that single leaf stirs driving a reaction pond fluid movement is less, and fluctuate weak, upper and lower circulating phenomenon is not obvious, easily causes mixing uneven, affects fully carrying out of course of reaction.
Summary of the invention
The technical issues that need to address of the present invention are, provide the stirrer-driven bar that a kind of shearing force is large, can make the abundant hybrid reaction of stirring thing.
Technical scheme of the present invention is: a kind of stirrer-driven bar, described drive rod is made up of upper drive rod and lower drive rod, be connected and transmitting torque with shaft coupling portion between upper drive rod with lower drive rod, shaft coupling portion turns to become and turns to contrary by lower drive rod with upper drive rod, and upper drive rod and lower drive rod lower end are respectively equipped with paddle and lower stirring paddle.
As preferably, be the bevel gear of three orthogonal engagements in described shaft coupling portion.
As preferably, described upper paddle is made up of with the brace being connected blade and drive rod a slice blade with lower stirring paddle.
Agitator shearing force of the present invention increases, the basis of the straight rod agitator of single leaf increases a coaxial agitation oar, arrange by difference 90 °, shearing force strengthens greatly, agitator is made to promote wider fluid, accelerate the fluctuation of fluid, the velocity perturbation of fluid also can promote hybrid reaction, improve production efficiency, on, lower stirring paddle reverse agitating function makes shearing force strengthen, significantly improve oppositely time flow phenomenon, define and circulate up and down preferably, effectively extenuate the straight rod of single leaf to stir the solid particle that hoop stream causes and deposit on reaction pool wall, decrease the dead band in reaction tank, to mixing, dispersion, heat transfer, fully carrying out all advantageously of the processes such as reaction.
Accompanying drawing explanation
Accompanying drawing 1 is the front schematic view of agitator of the present invention;
Accompanying drawing 2 is the front schematic view in drive rod and shaft coupling portion.
Detailed description of the invention
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described further:
As Fig. 1, shown in Fig. 2, the agitator of the present embodiment, comprise drive motors 1, drive motors 1 has drive end 2, drive end is connected to drive rod 2 times, drive rod is provided with paddle, drive rod is made up of upper drive rod 3 and lower drive rod 6, be connected and transmitting torque with shaft coupling portion 5 between upper drive rod 3 with lower drive rod 6, shaft coupling portion 5 turns to become and turns to contrary by lower drive rod 3 with upper drive rod 6, upper drive rod 3 and lower drive rod 6 lower end are respectively equipped with paddle 4 and lower stirring paddle 7, upper paddle 4 and lower stirring paddle 7 orthogonal on horizontal plane direction, arrange by difference 90 °, shearing force strengthens greatly, agitator is made to promote wider fluid, accelerate the fluctuation of fluid, the velocity perturbation of fluid also can promote hybrid reaction, improve production efficiency, it is the bevel gear 50 of three orthogonal engagements in shaft coupling portion 5, upper drive rod 3 is fixedly connected with a bevel gear 50 respectively with lower drive rod 6, then by another one bevel gear 50 gear motion transmitting torque, upper paddle 4 is made up of with the brace being connected blade and drive rod a slice blade with lower stirring paddle 7, and blade can be made to fluctuate in whipping process so less, overall structure is more firm.
Below only just the present invention preferably example be described, but can not be interpreted as it is limitations on claims.The present invention not only limits to and above example, and its concrete structure those skilled in the art that allow to change can make various change and distortion according to the present invention, only otherwise depart from spirit of the present invention, all should belong to the scope that claims of the present invention define.
