Description
Technical Field
The utility model relates to a stirring rake technical field especially relates to a dysmorphism stirring rake suitable for jumbo size reactor.
Background
The stirring paddle is used as a main structure in the reactor and has the function of transferring energy to fluid through the transmission shaft, so that good fluid circulation is achieved in the reactor, and the difference of the shape, structure and size parameters of the stirring paddle often makes the flow field distribution situation in the reactor have great difference, so that different stirrer structures can meet different reaction processes.
The straight blade stirrer is adopted in the large-size reactor, the straight blade stirrer is simple in structure and low in manufacturing cost, but during stirring, larger tangential flow can be generated, so that fluid in the reactor rotates around the stirring shaft, vortex is formed on the surface of the fluid when the flow speed is too high, the stirring and mixing effects of the fluid in the stirrer can be influenced due to the rotation phenomenon in the stirring process, the service life of the stirrer can be influenced, and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to prior art not enough, and provide a dysmorphism stirring rake suitable for jumbo size reactor, the stirring leaf includes straightway and bend section, the straightway with be the obtuse angle setting between the bend section, eliminate the reactor interior liquid as far as possible and beat the phenomenon soon to this increases the interior fluidic degree of turbulence of container, turns into axial flow and radial flow with the tangential flow, thereby improves mixed effect.
The utility model provides a technical scheme that its technical problem adopted is: a special-shaped stirring paddle suitable for a large-size reactor comprises a stirring shaft, wherein a plurality of stirring blades and connecting crosspieces are arranged outside the stirring shaft along the circumferential direction of the stirring shaft, the connecting crosspieces are arranged at one ends of the stirring blades, one ends of the stirring blades are fixed with the stirring shaft, and the other ends of the stirring blades are fixed with the connecting crosspieces; the stirring leaf includes straightway and bending section, straightway with be the obtuse angle setting between the bending section, the bending section is 7 style of calligraphy structures.
As a preferable technical scheme: the fixed end of the connecting crosspiece and the stirring shaft are arranged in an included angle mode.
As a preferable technical scheme: the included angle between the straight line section and the connecting crosspiece is less than 30 degrees.
