The both sides of female connector are formed with the oblique blade of sheet, and the end of oblique blade is formed with multilayer connection blade, and multilayer connection blade includes one
It is formed with bottom plate, bottom plate on blade and lower blade, upper blade and is formed with upper left blade and upper right blade, lower-left is formed with lower blade
Blade and bottom right blade.
The invention discloses a kind of agitating device of the plus hydrogenated reaction response kettle of hydrocarbon derivative, it is mainly characterized by stirring
Upper, middle and lower-ranking agitating paddle is set on axle, and the shape of three agitating paddles is consistent, but two agitating paddles and intermediate agitation oar up and down
The angle of horizontal direction is mutually staggered in 90 °, and adapter sleeve is formed with the middle part of agitating paddle, and adapter sleeve is enclosed on agitating shaft, adapter sleeve
Both sides are formed with inclined oblique blade, and the end of oblique blade, which is formed with multilayer connection slurry, multilayer connection slurry, is formed with four small blades,
The rotating speed of agitator is about in 200 ~ 350 turns/min during work, and the blade of the structure agitating paddle was both dropped by ingenious rational design
The low loss of catalyst, can make the good mixing of gas-liquid-solid three-phase in reactor, resistance is small again, significantly improve reaction effect
Really, product yield and production efficiency are improved, and reduces the collision and abrasion of catalyst, makes catalyst usage cycles significantly
Extension, catalyst usage amount is reduced, and is saved production cost, and reduction power of motor and rotating speed, is improved performance stability.
The agitating device of the plus hydrogenated reaction response kettle of hydrocarbon derivative of the present invention, the length L of the agitating paddle is 900mm,
The length N of multilayer connection blade is 156mm, and the multilayer connection blade of the left and right sides accounts for the 35% of whole agitating paddle.The oblique oar
The angle of inclination of leaf is 45 °.Appropriate size and angle of inclination, can effectively improve stirring reaction effect, improve product yield.
