Description
Technical field
The present invention relates to a kind of stabilizing equipment for being used to stablize agitating shaft.Specifically, the present invention relates to one kind to be used for
Stablize the stabilizing equipment of agitating shaft, the stabilizing equipment will not be hindered removes material from the container that stabilizing equipment is located at.Still
Specifically, the present invention relates to a kind of stabilizing equipment for being used to stablize agitating shaft, the stabilizing equipment to include vortex breaker.At it
In its arrangement, the present invention relates to a kind of stainless steel (such as, reactor), the stainless steel includes being used to stablize stirring
The stabilizing equipment of axis.
Background technology
Various processing need blending constituent (such as part).In some arrangements, component to be mixed is stream
Body either both fluid and solid.In general, blending constituent is to form required mixture in the mixing container.In chemical process
In, component to be mixed can be reactant and/or be the desired other components (such as, catalyst) of reaction.Can by this
A little components mix these components in the mixing container before being transferred to reactor.Alternately, can be mixed in the reactor
Close so that be carried out at the same time mixing and reaction.In this arrangement, the thing removed from stainless steel will be reaction product,
Optionally along with responseless component., it is necessary to which mixed reactant is to ensure coming into full contact between them in a variety of reactions,
Make it possible to that effective or improved reaction occurs.In a kind of arrangement, reactant to be mixed is liquid.In another cloth
Put in scheme, at least one liquid reactants need to be mixed with gas reactant.In addition, one or more solids can be with
Liquid reactants and/or gas reactant coexist.
Although various mechanism can be used for auxiliary mixing, the mechanical mixer for being used to stir component is typically used to provide
Required mixed-level.These mechanical mixers can provide power by driving unit (such as, motor).Driving unit leads to
It is frequently located in outside stainless steel, the rotation axis of driving unit driving and impeller blade attachment.When driving unit operates, rotation
Axis rotates, this then causes impeller blade to rotate, so as to promote blending constituent in the mixing container.
In simplest form, the end of the remote driving unit of rotation axis is not attached and therefore the end is
Free end.This arrangement is simple and therefore manufacture cost is low.However, because free end is not attached, rotation
Axis can swing and/or vibrate during use, this can cause not exclusively to mix and mixing apparatus may be caused to wear, especially
In the case where rotation axis is connected to driving unit.This is particularly problematic in large-scale stainless steel, holds in the large-scale mixing
, it is necessary to which longer rotation axis realizes acceptable mixing in device.
In solving the problems, such as these visual angle, it has been suggested that for the various designs for the free end for keeping rotation axis.It is a kind of
Such arrangement is so-called " stable bearing " component, and " stable bearing " component is located in stainless steel so that its
The free end of agitating shaft can be received and its stabilization is thus kept when agitating shaft rotates, thus prevent from swinging and reduce or
Eliminate and swing.
The example of stable bearing is described in US3149888 and US3489469.In this arrangement, bearing position
Outside stainless steel and rotation axis extends through the bottom of stainless steel before it is constrained in stable bearing.At it
In its arrangement, for example, in other arrangements described in US4660989, stable bearing is located in stainless steel.
In general, rotation axis is by the central axial line of stainless steel, to realize optimal mixing.However, because mixing is held
The outlet of device is usually located at the bottom centre of container, so being difficult to find the suitable position for stable bearing.Therefore inciting somebody to action
Outlet be positioned at needs at the bottom centre of stainless steel and by stable bearing be positioned at container bottom centre sentence it is just true
There are contradiction between the requirement coaxial with the central axial line of container of guarantor's rotation axis.
Solution is proposed for this, stable bearing is installed at the elevated position in stainless steel, made
It must export and can be aligned with stable bearing with central axial line.US2516918, US2657912, US2865615,
US3443794, US3489469, US4932787, US5088832, US5568985, US5618107, US7378431 and
The example of such stable bearing is described in US7402023.
Taken out in the case of being reactor in stainless steel by the outlet at stainless steel bottom from stainless steel
When taking blending ingredients or product stream, whirlpool can be formed.
In the case of raised position of the stable bearing above outlet, stable bearing is supported in raised position simultaneously
And the supporting leg itself therefore opened with the bottom interval of stainless steel can result in whirlpool.
Because whirlpool can cause gas to be entrained in from the liquid that stainless steel removes, it is unfavorable to form whirlpool
's.Whirlpool can also cause to separate not good enough or excessive pressure drops in downstream processes.Gas-entrained presence can also cause under
There is cavitation phenomenon in trip pump.
, can be by so-called " vortex breaker " in order to minimize the entrainment with steam in the liquid recycled from stainless steel bottom
On being directly installed at the top of the outlet inside container.These vortex breakers work to reduce liquid when liquid leaves discharge member
Some in angular speed.
An example of vortex breaker is described in US8439071.Vortex breaker includes the basket with cylindrical screen bulkhead, institute
Vortex breaker is stated to be assemblied on container outlet.Have vaned flowing modifier to be located in basket, to destroy radial directed stream.
The other examples of vortex breaker are described in US4696741, EP1309393, US8397751 and WO2013/096570.
Although the raised stable bearing of the prior art can be applied in combination with vortex breaker in principle, the knot formed
Structure will bear various inferior positions and defect.Because the supporting item for raised stable bearing itself adds whirlpool, they
Use especially exacerbate gas entrainment problem, vortex breaker must try to minimize gas entrainment problem.This extra complexity
Change can mean that vortex breaker cannot effectively prevent the formation of whirlpool and therefore energy minimization or will not prevent from forming entrained gas
Body.
Although the stable bearing of the above-mentioned type and vortex breaker are satisfactory and can continue to make in some cases
People is satisfied with, but it is desirable to providing a kind of improved arrangement, the improved arrangement allows to set stable bearing and prevents
Both whirlpool devices, but the complication degree of arrangement uses known type stable bearing and known type less than what can be contemplated that
The arrangement of the various combinations of vortex breaker.
