Abstract
The utility model relates to a paddle crescent open -ended agitator, the agitator includes the (mixing) shaft and sets up at a plurality of slice epaxial stirring paddle leaf of stirring, has offered the logical groove of a plurality of crescent on the every stirring paddle leaf respectively, stirring paddle leaf includes blade end and root of blade, blade end's pitch angle is 45~50, and the pitch angle of root of blade is 58~65. The utility model discloses simple structure, reasonable in design, the utility model discloses improving and having used the even grooved wing section agitator of crescent, form little swirl reaction system, the reduction fluid reduces the vibration of agitator to stirring paddle leaf's impact force, has promoted the efficiency of mass transfer and heat transfer.
Description
Technical field
This utility model relates to a kind of agitator, especially relates to a kind of blade Crescent-shaped openings
Agitator.
Background technology
Agitator is to make liquid, gas medium forced convection mixed uniformly device.Agitator
Type, size and rotating speed, to power of agitator distribution between overall flow and turbulence pulsation
All have an impact.It is, in general, that the power distribution of turbine type agitator is favourable to turbulence pulsation, and
Propeller mixer is favourable to overall flow.For same type of agitator, at power
Consume identical under conditions of, major diameter, slow-revving agitator, power is mainly consumed in totally
Flowing, beneficially micromixing；Minor diameter, high-revolving agitator, power is mainly consumed in
Turbulence pulsation, beneficially microcosmic mixing.
Existing agitator mixes poor, oar district partial cut work in use, often there is full tank
By the defect such as strong, power factor is higher.Thus cause, in industrialization process, there is part
Reaction mass transfer is unbalanced, halfway situation of conducting heat so that heat transfer and mass transfer usefulness are relatively low.
Utility model content
For the deficiency overcoming prior art to exist, this utility model provides a kind of crescent and opens
The aerofoil profile agitator of groove.
The agitator of a kind of blade Crescent-shaped openings, described agitator includes shaft, Yi Jishe
If the dry tablet stirrer paddle put on shaft, every stirrer paddle offers several respectively
Crescent groove, described stirrer paddle includes blade tip and root of blade, described blade tip
The angle of pitch be 45～50 °, the angle of pitch of root of blade is 58～65 °.
As preferably, the quantity of described stirrer paddle is three, and the blade of stirrer paddle is space
Warp surface, stirrer paddle cross section at any radius is wing shapes.This structure is the most micro-
The formation of whirlpool system.
As preferably, every stirrer paddle the most uniformly offers the centrage phase with stirring paddle
Three vertical crescent grooves.Form micro-whirlpool reaction system, can reduce in mass transfer simultaneously
Shearing and vibrations.
As preferably, the angle of pitch of described blade tip is 48 °, the angle of pitch of root of blade
It it is 62 °.The size of the angle of pitch, certain impact can be there is in the thrust for stirrer paddle, because of
This, the angle of pitch being suitable for is arranged, and can improve the performance of agitator further.
As preferably, a diameter of 450mm of stirrer paddle, the crescent moon radius of the radian of groove is
18mm。
This utility model simple in construction, reasonable in design, this utility model improves and employs crescent moon
The aerofoil profile agitator that shape is uniformly slotted, forms micro-whirlpool reaction system, reduces fluid to stirring paddle
The impulsive force of leaf, reduces the vibration of agitator, improves the usefulness of mass transfer and heat transfer.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of this utility model stirrer paddle；
Fig. 3 is the blade tip of this utility model stirrer paddle and the angle of pitch of root of blade is shown
It is intended to.
Detailed description of the invention
The utility model is described in further detail with specific embodiment below in conjunction with the accompanying drawings, but this reality
It is not limited to this by novel scope of the claimed.
With reference to Fig. 1～3, the agitator of a kind of blade Crescent-shaped openings, described agitator includes
If shaft 1 and the dry tablet stirrer paddle 2 being arranged on shaft, every stirrer paddle
Upper several crescent grooves 3 that offers respectively, concrete, on every stirrer paddle the most all
Even offer three the crescent grooves perpendicular with the centrage of stirring paddle；Micro-whirlpool can be formed
Whirlpool reaction system, can reduce the shearing in mass transfer and vibrations, lifting mass transfer and heat transfer simultaneously
Usefulness.
The quantity of described stirrer paddle 2 is three, and the blade of stirrer paddle 2 is spatial warping face,
Stirrer paddle cross section at any radius is wing shapes, and this structure is conducive to micro-whirlpool system
Formation.Described stirrer paddle includes blade tip 4 and root of blade 5, described blade tip
Pitch angle betabIt is 48 °, the pitch angle beta of root of bladeaIt is 62 °, stirrer paddle 2 straight
Footpath is Di=450mm, and the crescent moon radius of the radian of groove 3 is 18mm.
Claims (3)
1. the agitator of a blade Crescent-shaped openings, it is characterized in that: if described agitator includes shaft and the dry tablet stirrer paddle being arranged on shaft, several crescent grooves are offered respectively on every stirrer paddle, described stirrer paddle includes blade tip and root of blade, the angle of pitch of described blade tip is 48 °, the angle of pitch of root of blade is 62 °, and the crescent moon radius of the radian of groove is 18mm.
2. according to the agitator of the blade Crescent-shaped openings described in claim 1, it is characterised in that: the quantity of described stirrer paddle is three, and the blade of stirrer paddle is spatial warping face, and stirrer paddle cross section at any radius is wing shapes.
