Abstract
The invention discloses a stirrer which comprises a driving motor, wherein a driving end is arranged at the lower part of the driving motor; a driving rod is connected to the lower part of the driving end; stirring paddles are arranged on the driving rod; the driving rod consists of an upper driving rod and a lower driving rod; the upper driving rod and the lower driving rod are connected by virtue of a coupling part and transfer a torque; the rotating direction of the lower driving rod is changed to be opposite to that of the upper driving rod by virtue of the coupling part. According to the stirrer, the shear force is increased, a coaxial stirring paddle is additionally arranged on the basis of a single-blade straight stick stirrer, the stirring paddles are arranged in an angle of 90 degrees at intervals, and the shear force is greatly improved, so that fluid in a wider range is pushed by the stirrer, fluctuation of the fluid is accelerated, a mixed reaction can be promoted by speed fluctuation of the fluid, the shear force is enhanced due to stirring of the upper and lower stirring paddles in the opposite directions, a phenomenon that solid particles are deposited on the wall of a reaction tank due to annular flow of the single-blade straight stick stirring is effectively relieved, a dead zone in the reaction tank is reduced, and full operations of the processes such as mixing, dispersing, heat transferring and reacting are promoted.
Description
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 that is applied to Chemical Manufacture industry is different, wherein the straight rod agitator of single leaf because simple structure, production cost be low, easy to maintenance etc., be used widely by feature, but there are several shortcomings in the straight rod agitator of single leaf in production application: one, shearing force is little, single leaf stirs because shearing force is little, the hoop stream effect producing is obvious, and longitudinal stream is relative with slipstream to be weakened.This " turning round and round " phenomenon easily causes reaction pool wall raw material deposition, causes raw material loss.Dead band in pond can affect reaction effect and product quality greatly simultaneously; Two, react insufficient, the scope that single leaf stirs driving a reaction pond fluid movement is less, and a little less than fluctuation, upper and lower circulating phenomenon is not obvious, easily causes mixing inequality, affects fully carrying out of course of reaction.
Summary of the invention
The technical issues that need to address of the present invention are that the agitator that a kind of shearing force is large, can make to stir the abundant hybrid reaction of thing is provided.
Technical scheme of the present invention is: a kind of agitator, comprise drive motors, drive motors has drive end, under drive end, be connected to drive rod, drive rod is provided with paddle, described drive rod is comprised of upper drive rod and lower drive rod, between upper drive rod and lower drive rod, with shaft coupling portion, be connected and transmitting torque, shaft coupling portion becomes turning to of lower drive rod and upper drive rod switched in opposite, upper drive rod and lower drive rod lower end are respectively equipped with paddle and lower stirring paddle, and upper paddle and lower stirring paddle are orthogonal in horizontal plane direction.
As preferably, in described shaft coupling portion, be the bevel gear of three orthogonal engagements.
As preferably, described upper paddle is comprised of with the brace that is connected blade and drive rod a slice blade with lower stirring paddle.
Agitator shearing force of the present invention increases, on the basis of the straight rod agitator of single leaf, increase a coaxial paddle, by differing 90 °, arrange, shearing force strengthens greatly, make agitator promote wider fluid, accelerated the fluctuation of fluid, the velocity perturbation of fluid also can promote hybrid reaction, improved production efficiency, on, lower stirring paddle reverse agitating function strengthens shearing force, obviously improved oppositely time flow phenomenon, formed circulation up and down preferably, effectively having extenuated the straight rod of single leaf stirs the solid particle that hoop stream causes and deposits on reaction pool wall, reduced the dead band in reaction tank, to mixing, disperse, conduct heat, fully carrying out of the processes such as reaction is all comparatively favourable.
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 of drive rod and shaft coupling portion.
The specific embodiment
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 comprised of upper drive rod 3 and lower drive rod 6, upper drive rod 3 is connected and transmitting torque with shaft coupling portion 5 with 6 of lower drive rods, shaft coupling portion 5 becomes turning to of lower drive rod 3 and upper drive rod 6 switched in opposite, upper drive rod 3 and lower drive rod 6 lower ends are respectively equipped with paddle 4 and lower stirring paddle 7, upper paddle 4 and lower stirring paddle 7 are orthogonal in horizontal plane direction, by differing 90 °, arrange, shearing force strengthens greatly, make agitator promote wider fluid, accelerated the fluctuation of fluid, the velocity perturbation of fluid also can promote hybrid reaction, improved production efficiency, it in shaft coupling portion 5, is the bevel gear 50 of three orthogonal engagements, upper drive rod 3 is fixedly connected with respectively a bevel gear 50 with lower drive rod 6, then by another one bevel gear 50 gear motion transmitting torques, upper paddle 4 is comprised of with the brace that is connected blade and drive rod a slice blade with lower stirring paddle 7, can make blade fluctuate in whipping process so less, and 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 according to the present invention various changes and distortion, only otherwise depart from spirit of the present invention, all should belong to the defined scope of claims of the present invention.
