Description
Technical field
The present invention relates to solid and liquid mixing equipment field, especially superfine powders mixed with liquid generate high viscosity or
The equipment of high concentration liquid, the invention further relates to a kind of impeller assemblies for solid and fluid mixing apparatus.
Background technique
In industrial circle, many liquid raw materials are mixed by powder and liquid, and especially superfine powder is such as received
Mixing dispersion or mixing of the powder of meter level in a small amount of liquid are separated into highly viscous mixed liquor, for example, be applied to lithium from
The slurry in sub- battery plus-negative plate field.Generally, entire mixed process can be divided into three phases, break up, infiltrate and disperse.
In the stage of breaing up, powder passes through the isostructural stirring of blade from big agglomerate, becomes rough pulverulence.In invasive stages,
Powdered powder is contacted with liquid, but with the development of powder technology and nanotechnology, powder specific-surface area detection increase tendency
Obviously, surface can adsorb a large amount of gas, form the mistake of highly viscous slurry into a small amount of liquid in dispersion of ultrafine powder
Cheng Zhong, powder granule sufficiently infiltrate very difficult with liquid, and the distribution of powder granule in a liquid also can be very uneven, or even meeting
Situations such as agglomerating, certainly, since this stage powder granule can also enter in liquid, so one can also be regarded as
The pre-mixing stage of solid and liquid.In dispersion stage, decentralized processing can be carried out again to the outstanding mixed liquid by infiltrating or being pre-mixed,
Distribution consistency of the powder granule in outstanding mixed liquid is allowed to reach the requirement of production.In this stage, it is mainly cut using powerful
Shear force is completed to disperse agglomerate that may be present in the mixed liquid of pre- suspension, agglomeration etc., and powder granule is equably squeezed into institute
Have and participates in mixed liquid.But since infiltration and requirement of the dispersion process to mixing apparatus are not consistent, in such case
Under, good mixed effect cannot be reached using single hybrid mode, so, in the prior art by the infiltration of powder and liquid
Special equipment is respectively adopted to complete in the dispersion process of journey and powder in a liquid, and effect is better mixed to reach.
CN109173815A discloses a kind of equipment for hybrid solid and liquid, and as shown in Fig. 1, including solid supplies
To device 101；Fluid Supplying apparatus 102；Liquid distributor chamber 103, the liquid supplied are allocated wherein with predetermined amount of flow；
The solid is transported to mixing chamber 105 from solid feeder by screw rod drawing-in device 1041 by Solid Conveying and Melting room 104；It is mixed
Room is closed, the solid and the liquid for being supplied are mixed to form suspension；And rotor chamber 106, the suspension is at this
It is rotated in rotor chamber and is exported from the outlet of the rotor chamber, vacuum state is formed in the working region, thus at described turn
The entrance region of seed cell generates swabbing effect, which substantially the air of the surface of solids supplied is discharged, and powder exists
Before contact liq, the air of powder surface leaves powder, and powder contacts the abundant quick leaching for realizing powder and liquid with liquid again
Profit.But the equipment is only capable of completing the impregnation process of powder and preliminary dispersion, although the intracorporal gas of powder is largely siphoned away,
Be conducive to the infiltration of powder, but since stirring action is not strong, it is weaker to the shearing force of outstanding mixed liquid, so still there is part powder
The problem of body does not scatter sufficiently in a liquid, obtained outstanding mixed liquid can not be directly used in practical life in many cases,
It produces, and to carry out a high speed dispersion process again, thoroughly by evenly dispersed to the outstanding mixed liquid of the powder granule for forming agglomerate in powder
In the middle.
CN105148766B discloses a kind of high speed dispersing device, as shown in Fig. 2, point of feed inlet is equipped with including lower end
Bucket, the dispersion wheel being placed in dispersion bucket are dissipated, and the main shaft for driving dispersion to take turns, main shaft extend and are driven to the top of dispersion bucket
Connection has driving source, and the upper end of dispersion bucket is equipped with striker plate, and the top of striker plate is equipped with the discharge tank with discharging chamber；It further include setting
Deflector above feed inlet, deflector are located at the lower end of dispersion wheel.This method is that the material of dispersion will be needed to pass through from feed inlet
The blocking shunting function for crossing deflector send material to the sky between high-speed rotating dispersion wheel and fixed dispersion bucket
Gap is dispersed the top for being moved to dispersion wheel, and the material after dispersion flow to discharging chamber after the filtering of tubular filter structure,
It is flowed out by discharge port；Fail to be blocked across the material of tubular filter structure to the inner cavity of dispersion wheel and to re-start dispersion mixed
It closes.This high-speed dispersion equipment, advantage are that the peptizaiton time is long, and effect is good, and disadvantage is exactly to belong to autonomous device, be can be only done
Slurry is spread the work, and is unable to complete solid-liquid premixing and is closed work, is more unable to complete and detaches the air of powder surface and realize
The efficient infiltration of liquid and powder, and then lead to the difficulties in dispersion of powder in a liquid, the time required for dispersing is very long, leads
Cause energy consumption required for the dispersion of powder in a liquid very high.Motor speed high energy consumption is big, and volume is big, it is also necessary to individually charging
Mechanism and discharging mechanism etc., structure is complicated, and cost increase is obvious.
Belong in the CN207667471U patent of our company, the solid-liquid mixing for disclosing a kind of suitable high-viscosity material is set
It is standby, as shown in Fig. 3, comprising: screw feed module, in shell and for conveying powder to be mixed；Liquid distribution mould

Block rotates coaxially；Slit is provided between dispersion tube and the inner wall of shell, the outer wall of dispersion tube is laid with multiple dispersion holes.To
Mixed powder is dispersed by hybrid blade 44 and dispersion impeller 45 in mixing dispersed modules with liquid and/or is crushed and mixed
The dispersion hole 42 closed, and opened up by 41 outer wall of dispersion tube reaches in slit, solidliquid mixture when by dispersion hole 42 by
Agglomerated particle is opened to Strong shear effect and is dispersed.The working principle of the equipment is, using dispersion tube 41 rotation by liquid into
The liquid agitation that expects pipe 31 flows into is rotated, and is formed moisture film on dispersion tube surface, is arrived powder " beating " using hybrid blade 44
Outstanding mixed liquid is formed in dispersion tube 41, is then further mixed again by the dispersion tube of lower part.But by actual production
Accumulation verifying, although above-mentioned mixing apparatus mixed effect increases than old equipment, there is also several defects: first,
Since common blade to be used gets to powder in dispersion tube, targeted place is not made to the gas wrapped up around powder
Reason, powder effect of impregnation is very poor, and remained on surface gas is relatively more.In the shape that this powder surface air does not empty to greatest extent
Under state, dispersion tube has prematurely intervened premixing work, causes the powder agglomerate not infiltrated sufficiently to be mixed blade 44 and is thrown to
In dispersion tube 41, it is easy to block dispersion hole 42, optimal premixing effect is not achieved, affect subsequent dispersion step.Second,
It is limited by working principle, dispersion tube must be from top to bottom through setting, and area and volume are all very big, and needs and main shaft
It rotates together, structure is complicated, and energy consumption is higher.Third, since dispersion tube participates in entire infiltration and dispersion process, powder upon into
When entering to be arranged the region of stirring blade and dispersion tube, do not broken up, at the same time, blade and cylinder sufficiently to many powder agglomerates
The distance of wall is but very close, causes big agglomerate that can have enough time being broken up not yet just directly having been got in dispersion tube, causes
Disperse hole plug, processing speed and the ability decline of whole equipment are not able to satisfy the requirement quickly produced.4th, due to mixing
Blade, dispersion tube and dispersion impeller use the same main shaft and motor, and without using frustoconical impeller, wheel bottom edge
Linear velocity is simultaneously unhappy, mixes and throws away effect and be affected, and cannot form effective vacuum in discharge port, hangs flow velocity under mixed liquid
Spend unhappy, feedstock processing speed is undesirable.5th, the dynamic direction of outstanding mixed liquid stream is consistent with the direction that dispersion tube is arranged, and under
Portion is not provided with impeller, and the speed that outstanding mixed liquid enters lower part dispersion hole is lower, and lesser shearing force affects dispersion effect, and
If dispersion tube length is inadequate, have the outstanding mixed liquid in part cannot be introduced into dispersion hole at all.

As shown in figs. 10-12, the present invention is a kind of solid and liquid mixing equipment, including shell 14；At least one solid
Solid is transported to mixing chamber 11 through Solid Conveying and Melting room 10 by feedway 9；At least one fluid Supplying apparatus 12, liquid is passed through
Liquid distributor chamber 13 is transported to mixing chamber 11；Mixing chamber 11 is limited by ontology 2 and the corresponding portion of shell 14, utilizes impeller 1
It rotates the swabbing effect generated and solid and liquid is mixed to form suspension；And dispersing chamber 15, it is set to the mixing chamber
Between the outlet of 11 lower flow passages and output mechanism 26, the part portion corresponding to shell 14 except ontology 2 is removed by impeller assembly
Divide and is limited, the outstanding mixed liquid for utilizing the shear action dispersion mixing room 11 of porous plate 5 to flow out.Porous plate 5 is fixed on mixing apparatus
Shell 14 or impeller bottom plate 3 on.
The shell 14 of mixing apparatus, mainly plays support and as chamber shell, for example is used to support and installation is electric
Machine 20, main shaft 21, solid feeder 9, fluid Supplying apparatus 12 etc., shell 14 are usually to be spliced by several parts, because
To need to install the components such as impeller 1, porous plate 5, main shaft 21 inside shell 14.After mixing apparatus is completed, shell 14
With all parts being mounted thereon, Solid Conveying and Melting room 10, liquid distributor chamber 13, mixing chamber are substantially defined from top to bottom
11, these core chambers of dispersing chamber 15.But this restriction, which only represents one kind, artificially to be divided, mainly from completion function
Can angle limit.The specific line of demarcation of actual mixing apparatus, these possible chambers is not obvious, can not be with specifically
Shape limits dispersing chamber etc., still, from the positional relationships of these chambers, by which component is constituted and realized function
It sees, these chambers are very clearly again.For emphasis, mixing chamber 11 generally comprises the ontology 2 of impeller 1, and surrounds this
This partial shell of body portion, this two parts substantially define the space of a truncated cone cylinder, in this space, by injection
Liquid out and the powder broken up contact with each other, and preliminary mixing is completed under the Stirring of hybrid blade 4.Dispersion
Room 15 may include the other component of the impeller assemblies such as bottom plate 3, porous plate 5, discharge blade 6, and surround these components this
Partial shell, this two parts substantially define the space of a cylinder, and in this space, what is thrown away from mixing chamber 11 is outstanding mixed
Liquid under the action of discharge blade 6, is brought by rotation to output mechanism across the channel of the compositions such as bottom plate 3, porous plate 5, top plate 7
26, complete the further shearing and dispersion to outstanding mixed liquid.
Solid feeder 9 is for will need mixed solid to be transported to mixing chamber 11 from feed entrance point.Solid supply dress
Set 9 by screw rod drawing-in device 22 by solid material (usually various powder materials) from hopper or feed bin through Solid Conveying and Melting room
10 are transported to mixing chamber 11.Screw rod drawing-in device 22 solid is continuous, uniform can be sent into mixing chamber 11, to avoid solid
There is the excessive or very few situation of solid when mixing chamber 11 contacts in body and liquid, and solid excessively then be easy to cause solid
The case where body agglomerates and blocks also brings solid and liquid to infiltrate and uniformly mix the problem of difficulty increases；Solid is excessively few then
It causes same a collection of all solids and the uniformly mixed difficulty of liquid big, needs to increase circulation mixing number realization with a batch all solids
With the uniform mixing of liquid.The present invention, on the one hand can be to avoid mixing chamber 11 by conveying of the screw rod drawing-in device 22 to solid
Swabbing effect influence that the suction of solid is generated, on the one hand Solid Conveying and Melting continuous, uniformly can be entered into mixing chamber
11 mix with liquid, realize the uniform of the infiltration with batch of solid and liquid, reduce the cycle-index of mixing.
It is significant to note that solid feeder 9 should not be construed simply as to screw rod feeding dress in the present invention
It sets, as long as being able to achieve the uniform feeding device continuously conveyed of solid, can be applied in the present invention.In addition, depositing
In the case where a plurality of types of solids need to infiltrate and mix, solid feeder of the invention is filled using multiple screw rod feedings
Setting the mode conveyed respectively to many kinds of solids is also the technical solution within the scope of protection of the invention.
Fluid Supplying apparatus 12 is for storing and supplying liquid, wherein the liquid includes the case where referring to suspension, described
Suspension refers to liquid and the mixed liquid of solid.Fluid Supplying apparatus 12 can be multiple, a part of fluid Supplying apparatus
Liquid is supplied, a part of fluid Supplying apparatus becomes the supply of the suspension after suspension for liquid.Liquid distributor chamber 13
Liquid for being supplied fluid Supplying apparatus 12 is allocated with predetermined amount of flow.It is described to be divided liquid with predetermined amount of flow
It is sufficient can to make the fluid flow in liquid distributor chamber 13 with liquid, and liquid is evenly distributed in liquid distributor chamber 13,
For example, can be adjusted by the entry nozzle quantity of liquid distributor chamber 13, the liquid delivery pump that fluid Supplying apparatus 12 connects (saves
Slightly be not drawn into) revolving speed change or both the distribution that Binding change realizes fluid flow respectively.To guarantee liquid in liquid
The destruction of cavitation erosion is not generated in distributor chamber 13, so that equipment be avoided to be damaged, realizes that liquid enters mixing chamber 11 and consolidates yet
Body is not in hole when contacting, and largely avoids solid from entering liquid hole and forms agglomeration, equipment is caused to block.When
So, the flow direction that liquid can be controlled by adjusting the angle of entry nozzle, realizes the control of fluid flow.
Mixing chamber 11 is used for the solid entered and liquid infiltration, is mixed to form suspension.In the present invention, to make
The Solid Conveying and Melting room 10 of mixing apparatus and mixing chamber 11 are isolated with outside air, can be by the way that valve is arranged in solid feeder 9
The mode of door is realized and device external air insulated.Solid is continuous by screw rod drawing-in device 22, uniformly inputs mixing chamber
11, liquid distributor chamber 13 inputs mixing chamber 11 by liquid adequate volume, continuously and uniformly with scheduled flow.Since screw rod feeding fills
The sealing for setting 22 and its input port, when mixing chamber 11 rotates so that liquid accelerates to pass through mixing chamber 11 and be discharged, mixing chamber 11
Swabbing effect is produced, so that the air of 11 front of Solid Conveying and Melting room 10 and mixing chamber rapidly enters 11 rear portion of mixing chamber side by side
Out, so that conveying chamber 10 and 11 front of mixing chamber enter proximal to the state of vacuum, the surface of solids in Solid Conveying and Melting room 10
Air is detached from the surface of solids in vacuum environment, so that solid eliminates the air on surface substantially before contacting with liquid, from
And liquid is made to be more easier to infiltrate solid.
Mixing chamber 11 includes annular gap 23, and the annular gap 23 is by frustum-like shape impeller body 2 and corresponding shell
A part of annular wall of body 14, which limits, to be constituted.The diameter of section of frustum-like shape ontology 2, along from 11 entrance of mixing chamber to outlet
Direction integrally gradually increase, for frustum-like shape ontology 2 under the drive of main shaft 21, the suspension on surface is realized accelerates fortune from top to bottom
It is dynamic, the swabbing effect of 11 outlet area of mixing chamber is on the one hand generated during accelerating herein, accelerates flow velocity；On the other hand also make
Solids in suspension superficial air further leaves solid, realize solid and the more uniform infiltration mixing of liquid.
The Solid Conveying and Melting room 10 of 22 output end of screw rod drawing-in device of mixing apparatus further includes dispersing device 24, for example is dispersed
Centrum, sieve, powder break up disk, screw or dispersion pin.Screw rod drawing-in device 22 is enforceable to the axial conveying chamber of solid,
So that solid is squeezed through above-mentioned dispersing device 24, breaing up for solid is realized, is also beneficial to solid in Solid Conveying and Melting room 10
The air on surface is detached from solid, mixes with liquid in the uniform of mixing chamber to be conducive to solid.
Dispersing chamber 15 removes the part except ontology 2 by impeller assembly and is limited with a part of corresponding shell 14,
It is set between the lower flow passage outlet of mixing chamber 11 and output mechanism 26.It can by the course of work and working principle of the invention
Know, Solid Conveying and Melting room 10, liquid distributor chamber 13, mixing chamber 11 and dispersing chamber 15, not instead of independent chamber one by one,
It interconnects, only because since the needs of technique, liquid and solid entering mixing apparatus, sequentially enter above-mentioned different
Chamber completes corresponding processing, obtains corresponding treatment effect.Dispersing chamber 15 is connected to mixing chamber 11 and output mechanism 26
Together, the differentiation from each other in structure boundary is not obvious, but their function is but completely different.In mixing chamber 11
Exit, solid carried out infiltration and a degree of mixing with liquid, formd the outstanding mixed liquid with powder granule.
And since the rotation speed of 1 lower edge of impeller is much larger than top, the movement velocity of the outstanding mixed liquid of discharge mixing chamber 11
It is just very fast.It is verified, porous plate 5 is set in position downstream, is flowed using the shear action dispersion mixing room 11 of porous plate 5
The outstanding mixed liquid of high-speed motion out, can basically reach the effect for using independent high speed disperser in the prior art, and be not easy
Block dispersion hole 25.Although this merely defines it and completes corresponding function in addition, porous plate 5 is arranged in annular base plate 3
Position, do not limit its fix position, in fact, porous plate 5 of the invention can be fixed on mixing apparatus shell 14 or
On the bottom plate 3 of impeller assembly.When being fixed on shell 14, the dispersion effect for hanging mixed liquid is more preferable, but at this time simultaneously due to porous plate 5
It does not rotate, discharge velocity will receive certain influence.When being fixed on bottom plate 3, discharge velocity is preferable, but at this time due to porous plate 5
It is rotated with impeller, the dispersion effect of outstanding mixed liquid will receive certain influence.Certainly, the fixed form of porous plate 5 is varied,
It is not limited to above two mode, as long as the fixation of porous plate 5 can be completed, guarantees system worked well.
For traditional mixing apparatus, stirring blade is usually all isodiametric, that is to say, that in the horizontal direction may be used
To generate stronger rotary impact power and shearing force, so, the side of prior art intermediate diameter stirring blade can be arranged
The structure of mixed effect, such as cylindrical porous plate can be enhanced, still, the deficiency of this design is also it will be apparent that such as more
Blocking, reduction of solidliquid mixture vertical direction conveying speed of orifice plate etc., these have been carried out in detail in background technology part
Describe in detail bright, details are not described herein.For these problems, the present inventor devises a kind of solid and liquid mixing equipment, uses
Truncated cone shape impeller and non-equal diameter blade so that outstanding mixed liquid after impeller linear velocity increase obvious, taken into account well pre-
Mixed effect and discharge velocity.But the dispersion consistency effect of this premixing machine is unable to reach production when using certain raw materials
It is required that for this purpose, we utilize the original structure of this premixing machine and operating mode, as soon as only rely on increased porous plate, it is complete
At the organic combination of pre-mixing function and divergent function, rather than two individual equipment are simply connected into one big set
It is standby.
As shown in figs. 4-7, the present invention uses improved impeller assembly, including impeller 1, impeller packet in mixing apparatus
Frustum-like shape ontology 2 is included, body inclined surface is formed with several hybrid blades 4 from top to bottom, and impeller assembly further includes setting at this
The porous plate 5 of body lower outside, substantially radially several discharge blades 6 on the outside of porous plate are arranged in direction.Porous plate is fixed
On the shell 14 of mixing apparatus or the impeller of impeller assembly.Discharge blade 6 is fixedly connected with impeller 1, and synchronous with impeller
Rotation, it is solid by the annular base plate 3 of wheel bottom is arranged in and/or is arranged in above wheel bottom annular deck 7 and impeller 1
Fixed connection.Discharge blade 6 is arranged between top plate 7 and bottom plate 3, and top plate 7 and bottom plate 3 limit outstanding mixed liquid discharging channel jointly.
In the present invention, impeller 1 will include the ontology 2 of a frustum-like shape, this is because impeller 1 is existed as rotor
, so being inevitably connected in the axial direction with main shaft, since the presence of connection structure can occupy certain body
Product, so ontology 2 will usually exist with the shape of truncated cone, it is of course also possible to referred to as truncated cone shape.In addition, can in Fig. 7
To be clearly seen at the top of impeller 1 there are a cylindric interconnecting piece 16, but interconnecting piece 16 is it is not necessary to one be arranged
Component can design inside frustum-like shape ontology 2 completely with the interconnecting piece of main shaft 21, for the present invention, if being not provided with connecting
Portion 16, can be with unrestricted choice.In addition, 2 bottom of ontology is for technique requirement, it is also possible to a smaller bottom edge be arranged, but right
The global shape of impeller influences less, to remove when necessary.If being provided with interconnecting piece 16, when designing hybrid blade 4,
Comprehensively consider the final diameter of section of impeller 1, in order to avoid occur stress during Stirring and load non-uniform ask
Topic.Hybrid blade 4 can be started setting up from interconnecting piece 16, can also be started setting up from ontology 2.But design anyway, it mixes
The height relative to ontology 2 of hing straps 4 wants much the same, while making the shape of shell 14 and the tilted shape of impeller 1
It matches, can be achieved with the swabbing effect emphasized in the present invention.Herein, lower part is the term of an expression Position Approximate,
If entire impeller 1 is divided into three parts of upper, middle and lower from top to bottom, the meaning of lower part relatively good will be understood.Certainly, real
The shape of porous plate 5 is not necessarily cylindrical shape in the design of border, and according to the different shape of impeller 1, porous plate 5 can also follow impeller
Ontology 2, bottom plate 3, even shell 14 shape make certain change, in addition, as the position that porous plate 5 is placed is different,
In order to preferably play shear action, or in order to better adapt to runner, the shape and set-up mode of porous plate 5 are likely to
Some changes occur.
Annular base plate 3 can play the role of the outstanding mixed liquid movement direction of guidance, because hanging mixed liquid from after mixing chamber discharge, meeting
It is tilted with a higher speed and rotates the bottom housing section for rushing at shell 14, and porous plate 5 is usually to be vertically arranged,
In this way, outstanding mixed liquid cannot be directly flushed on porous plate 5, meanwhile, the outstanding mixed liquid in part, which is also had, by gap is directly discharged dispersion
Room.So all being passed through at a high speed at a proper angle in order to avoid the unordered flowing of outstanding mixed liquid also for the outstanding mixed liquid for guaranteeing all
Porous plate 5, we can consider to make full use of the effect of 14 bottom surface of shell, or in the bottom of impeller 1, increase by one horizontally outward
The bottom plate 3 of extension.In addition, annular base plate 3 can also play the role of fixed or place porous plate 5, porous plate 5 can pass through
Cyclic annular mounting flange side 8 is fixed to shell 14 or annular base plate 3, it is of course also possible to be soldered directly to annular base plate 3.
Since the present invention increases the component (porous plate 5) of its proper flow of blocking on the dynamic access of outstanding mixed liquid stream, this
Sample can clearly reduce the dynamic speed of outstanding mixed liquid stream, and still, the processing speed of mixing chamber 11 is again without because of subsequent access quilt
Stop and reduces.Therefore, in order to keep the processing speed of entire mixing apparatus, referring to Fig. 6-7, the present invention is in substantially radially side
To several discharge blades 6 being provided in 5 outside of porous plate, discharge blade 6 can be directly anchored on porous plate 5 (such as
Shown in Fig. 6).In addition it is also possible to which substantially radially direction is fixed with several discharge blades 6 in annular base plate 3, certainly, directly
Substantially radially the fixed several discharge blades 6 in direction are also feasible scheme on 2 lower end surface of ontology.In the present invention, from reality
From the perspective of existing function, usually several blades in 5 outside of porous plate can be interpreted as discharge blade 6, by the blade of inside
It is interpreted as hybrid blade 4.As shown in fig. 7, discharge blade 6 is fixedly arranged above annular deck 7, discharge blade 6 is arranged in 7 He of top plate
Between bottom plate 3, top plate 7 and bottom plate 3 limit outstanding mixed liquid discharging channel jointly.Due to discharge blade 6 have certain height and
Radical length, and top plate 7 is also substantially parallel with bottom plate 3, is combined with the part of bottom plate 3 in the outer part, is formed in the outside of porous plate 5
The outstanding mixed liquid flow passage of the annular of one base closed, the outstanding mixed liquid passed through from porous plate 5, can fully enter top plate 7 and bottom
Plate 3 limits outstanding mixed liquid discharging channel jointly.In some cases, discharge blade 6 can also be fixed by top plate 7 and impeller 1
Connection.The introducing of discharge blade 6 is equivalent to and in a disguised form increases the diameter of 1 bottom blade of impeller, and discharge blade 6 is the bottom of at
It is high-speed rotating under the drive of plate 3, under the cooperation of shell 14, the effect similar to centrifugal pump is produced, the centrifugation generated
Effect can form a kind of vacuum state in the outside of porous plate 5, and the liquid of 5 inside of porous plate is promoted to accelerate flow direction outside, so that
The process that outstanding mixed liquid passes through porous plate 5 becomes rapid and easy.In this way, just by discharge blade 6 effectively compensate for add it is more
5 bring kinetic energy rejection of orifice plate.By the setting of porous plate 5 in 6 inside of discharge blade, then the outer edge of discharge blade 6 can be set
The inner wall apart from shell 14 of meter is very close, can both guarantee that all outstanding mixed liquid all passed through porous plate 5, it is also ensured that dividing
It dissipates room and generates enough vacuum degrees, higher position is kept to manage speed.
Preferably, discharge blade 6 is roughly the same with the bending direction of hybrid blade 4, and hole 27 is provided on discharge blade 6.
The present invention is not particularly limited the quantity of hybrid blade 4 and discharge blade 6, only when discharge blade 6 and hybrid blade 4
Smaller to the mobile obstacle of outstanding mixed liquid when bending direction is roughly the same, speed loss is smaller.Further, since the material of processing is logical
It is often highly viscous slurry, so being provided with hole 27 on discharge blade 6, additional circumferential shearing force can be provided in this way, may be used also
To avoid the high pressure and high load capacity unfavorable to equipment is generated in dispersing chamber 15, highly viscous slurry is helped to be smoothly discharged.
Referring to Fig. 8 and 9, hybrid blade 4 can extend certain distance in the lower horizontal of ontology 2, discharge blade 6 with mix
Blade 4 is linked together in this part that the lower horizontal of ontology 2 extends.It is this to be fixedly connected with design, by the edge of hybrid blade 4
It is reduced to the distance of porous plate 5 minimum, stirring well, guiding and acceleration can be played to outstanding mixed liquid, using prolonging
Blade after length can be thrown away outstanding mixed liquid in the channel that discharge blade 6 limits with higher speed, allow the cutting of porous plate 5
The effect of cutting is amplified.Meanwhile hybrid blade 4 and discharge blade 6 can be linked together by a bit of connection rib, it is not necessarily to
By bottom plate 3 or top plate 7, the overall structure of impeller assembly can simplify.
The height of porous plate 5 and the height of the horizontal continuation on bottom plate 3 of hybrid blade 4 are almost the same, or with top
The height of plate 7 is almost the same.This is allowed to match with the unit coordinates of surrounding primarily to the accurate height for limiting porous plate 5
It closes, the common effect for completing to limit outstanding mixed liquid flow channel.Because outstanding mixed liquid is in the flow passage of dispersing chamber 15, it should determine
Between top plate 7 and bottom plate 3, so to guarantee that porous plate 5 can completely enclose channel between the two, all outstanding mixed liquid is allowed all to pass through
Cross the shearing decentralized processing of porous plate 5.
Porous plate 5 has cyclic annular mounting flange side 8.As shown in figure 4, the shape of porous plate can under certain installation conditions
When can change, for example need to be mounted to shell 14, a selection well is undoubtedly by mounting flange side 8,
It can achieve the requirement of stability.It is of course also possible to installed porous plate 5 to bottom plate 3 using flange, compared to by porous plate
5 are soldered directly to shell 14, bottom plate 3 or top plate 7 or even hybrid blade 4, and the flexibility of this mode is higher, repair and replacement
It is more convenient.
In the case where being not provided with bottom plate 3 of impeller 1, hybrid blade 4 can on the lower end surface of ontology 2 horizontal extension
Premixing effect equally can be enhanced in certain distance, improves flow velocity, and outstanding mixed liquid is guided to enter runner.Designer can be flexible
The position of hybrid blade 4, quantity is arranged in ground.And the ginseng such as its length, shape, curvature can be adjusted flexibly according to actual needs
Number can give designer bigger design space.In addition, there is also 2 inclined surfaces of ontology to be not provided with the mixing by the present invention
The embodiment of blade 4 can just reach the requirement of certain slurry productions merely with the rotation immixture of impeller 1, simplify
The structure of equipment improves the durability degree of equipment.Certainly, it under this design, is introduced separately into and is fixed on 2 lower end surface of ontology simultaneously edge
The hybrid blade 4 that radial direction extends can equally greatly increase the velocity of discharge of outstanding mixed liquid, can make up impeller to a certain extent
Without hybrid blade, impeller handles the insufficient defect of the velocity of discharge for middle part and top.
