Abstract
The utility model discloses a stirrer which comprises a driving motor, wherein a driving end is formed below the driving motor; a driving rod is connected below the driving end, is provided with stirring paddles, and consists of an upper driving rod and a lower driving rod; the upper driving rod and the lower driving rod are connected through a shaft coupling part and transmit torque; the rotation direction of the lower driving rod is turned to be opposite to the rotation direction of the upper driving rod through the shaft coupling part. According to the stirrer, the shear force is increased, and a coaxial stirring paddle is arranged on the basis of a single-blade straight-rod stirrer in a way of being deviated by 90 degrees, so that the shear force is enhanced greatly, fluid in a large range can be pushed by the stirrer, the flow of the fluid is accelerated, and the speed fluctuation of the fluid can promote mixing reaction. The shear force is enhanced due to opposite stirring of upper and lower stirring paddles, so that deposition of solid particles on a reaction pond wall due to single-blade straight-roller stirring annular flow is slowed down effectively, the areas of dead zones in a reaction pond are reduced, and the complete performing of the processes such as mixing, dispersing, heat transfer and reacting is facilitated.
Description
Technical field
The utility model 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.
Utility model content
The utility model technical issues that need to address are that the agitator that a kind of shearing force is large, can make to stir the abundant hybrid reaction of thing is provided.
The technical solution of the utility model 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.
The utility model agitator shearing force 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 the utility model agitator;
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 utility model 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 with regard to the utility model preferably example be described, but can not be interpreted as it is limitations on claims.The utility model not only limits to and above example, its concrete structure those skilled in the art that allow to change can make various changes and distortion according to the utility model, only otherwise depart from spirit of the present utility model, all should belong to the defined scope of the utility model claims.
