Description
Technical field
The present invention relates to a kind of compound Mixing Machine, in particular for cement stabilized soil, cement concrete, cement mortar
With the mixer and technology of asphalt.
Background technology
The function of mixer is that the various materials prepared are mixed into uniformly by stirring, and conform to quality requirements
Compound.Conventional mixer is generally divided into self-dumping mixer and forced mixer at present, the stirring of this two kinds of mixers
Pattern is referred to as static(al) stirring.Self-dumping mixer is that its internal flow distribution plate is carried out to material in cylinder when being rotated using mixing drum
It is repeatedly lifted up segmentation, gravity to fall, so that the purpose that material constantly disperses, is distributed and reaches uniform mix；Forced action type is stirred
Machine then sheared to material using the agitating shaft and its blade of rotation, extruded, is stirred and its rolling, convection current etc. is forced mix,
So that material, which is in relatively violent relative motion, obtains uniform mix.Because the stirring intensity of forced mixer is much larger than
Self-dumping mixer, can produce the preferable compound of relative mass.Therefore, forced mixer is progressively stirred instead of gravity type
Mix the trend of machine.By improving stirring intensity mixing quality can be made to obtain lifting to a certain extent, but static(al) stirring mode
Under be still extremely difficult to compound it is microcosmic on it is uniform.A, with cement class compound, such as cement stabilized soil, cement concrete and water
Exemplified by cement mortar etc., the material for stirring mixing by forced mixer can still find more " cement group under the microscope
Grain ", this be due to water surface tension effects under adhesive aggregation is formed, due to the entrance without water inside cement granule, generation not
The hydration reaction of cement, causes the waste of this part of cement, directly affects the maximization of the workability and intensity of compound.
B, by taking asphalt as an example, due to the sticky nature of pitch in itself, coarse aggregate under static(al) stirring mode in asphalt,
Fine aggregate, powder etc. are difficult to be evenly distributed, it is also difficult to allow powder fully to be merged with pitch, do not become high performance gelling material
Material, binder materials, fine aggregate equably can not be wrapped fully in the surface of coarse aggregate, or even are remained in miberal powder group, oil group etc.
Phenomenon, leaves obvious hidden danger of quality.
In order to solve the above-mentioned technical problem, cement class mixer in recent years employs stirring with vibrating the vibration being combined

Fixed or static, the other end is vibration source.Exciting force or oscillation intensity are it is obvious that and stirring power when having the work of this end of vibration source
The exciting force or oscillation intensity of input are then substantially very weak, and the vibration that this results in agitating shaft two ends is unbalanced, in mixing drum
Material uniformity is also just affected.Secondly, agitating shaft is directly connected by capacity eccentric bearing with vibrator, equivalent to directly stirring
Axle is mixed as vibrating shaft, agitating shaft also does while normal Stirring motion is done and gets rid of pendular motion, agitating shaft at a high speed in work
Weight itself is big and is rigidly set with by bearing with mixing drum, and high-power driving must be used by playing vibration force, generally be used
Driven to two 15KW and the motor of the above.Moreover, the connection key position of agitating shaft and vibrator --- capacity eccentric bearing
Load becomes very harsh, and the selection of this bearing is faced with heavily loaded and high-revolving two big paradox demand.Thus this structure
The vibration frequency upper limit is by larger limitation, and service life and stability are all undesirable, and the material in mixing drum absorbs vibration wave
Intensity is also unbalanced, and mixture quality is by larger restriction.
In addition, both the above Vibratory Mixing structure, due to directly using bearing, bearing block between agitating shaft and mixing drum
Deng rigidity suit, the exciting force of agitating shaft is by stronger retardance.Therefore, vibration kinetic equation loss is huge, and exciting force is also directly passed
Mixing drum is passed, and the vibration for stirring barrel then easily causes the isolation of material in cylinder in turn.Moreover, the vibration of mixing drum is also
Have influence on normal operation and the stability of other mechanical parts, mixing drum wall vibrations are derive under Vibratory Mixing pattern harmful
Product, it is necessary to overcome.

10 various materials are by agitating shaft 13, paddle in above-described shaft vibration forced mixer, mixing drum
Under the three-dimensional exciting force effect of rotation stirring and the vibration of piece 11 and mixing arm 12, stirring intensity is already maximized, disperse of gathering materials
More thoroughly, it is distributed more uniform.The need for can also be according to different material in stirring, the vibration frequency and width of vibrating motor
Degree can set or is adjusted by adjuster, the exciting force of agitating shaft is produced large and small cycles change, solve different material
To the corresponding demand of different frequency and exciting force, Vibratory Mixing is set to meet broader material scope, and finally can be by compound
Mixing quality is lifted to a new height.
In brief, the formation of any kind of compound intensity, all be unable to do without the adhesion solidification of binder materials；And
The lifting of stirring intensity can make compound tend to more be well mixed, and can form the more binder materials of quality product matter and allow
These binder materials are full and uniform to be distributed in inside compound, so as to form high performance compound.Mixer is from initial rolling
Cylinder gravity type stirring, develops into existing Double-horizontal-shaft action of forced stirring, is the compound brought to material stirring strength enhancing
The lifting of performance.Can cause because the stirring vane circumferential speed of action of forced stirring is too high material produce under the action of the centrifugal force from
Analysis, is restricted the lifting of stirring intensity.And shaft vibration forced action type stirring technique then breaches this limitation, by mixer
Stirring intensity have a new height again；The shaft vibration forced mixer of the present invention is even more that the potential of Vibratory Mixing is sent out
Wave a higher level.
By taking the stirring mixing of following two mixing material as an example, illustrate the effect that stirring plus vibration are produced：
First, the Vibratory Mixing of the cement class compound such as cement stabilized soil, cement concrete and cement mortar is included
1st, shaft vibration forced mixer of the invention makes mixing material pass through agitating shaft 13, stirring except keeping static(al) stirring
The rotation stirring of blade 11 and mixing arm 12, produces axial movement or the axle of superposition while producing circumference, radial cyclical movement
To shuttling movement, agitating shaft 13, stirring vane 11 and mixing arm 12 generate vibration under the drive of vibrating mechanism, and compound exists
Vibrate in the presence of strength ripple, thick, thin, the abundant disperse of the various materials of powder is uniform to merge, so that compound reaches macroscopically
It is uniform it is microcosmic on it is uniform；
2nd, due to the surface tension effects of water, it is existing that cement and water form " cement granule " in conventional static whipping process, easily
As therefore part of cement does not produce hydration reaction, causes the waste of this part of cement.After Vibratory Mixing, in the work of vibration wave
Under, " cement granule " can be broken up completely, and hydrated reaction of cement is abundant；Under vibration force effect, cement, water and fine aggregate fully melt
Close and form binder materials best in quality, allow compound intensity therefore to be lifted；
3rd, in the presence of stirring plus vibration, various compounds mutual impact several times, binder materials in stirring and vibration processes
Can preferably with aggregate secure bond, adhesiveness is largely increased, so as to improve the intensity of compound；Especially some are outmoded
Material, surface forms powder wax shell and oxidative phenomena, and Vibratory Mixing can break wax shell, clean aggregate table under the impact of exciting force
Bonding for face, binder materials and aggregate is more firm.And aggregate adhesiveness improves while compound intensity is improved, it may also reduce
Crack, the generation of disconnected plate；
4th, in the presence of stirring plus vibration, fine aggregate, powder and water obtain more uniform disperse, therefore also lift this portion
Divide the utilization rate of material, so as to reduce fine aggregate, powder consumption, the consumption of synchronous corresponding increase coarse aggregate, is compound intensity
Good skeleton basis is laid in lifting, so as to reach reduction disconnected plate, the generation in crack；
5th, in the presence of stirring plus vibration, thus it is possible to vary inside concrete bubble distribution and size, inside concrete is reduced
Deleterious bubbles, lifting concrete microstructure and durability, lifting antiseepage, moisture-proof anticorrosive and antifreeze ability；
6th, in the presence of stirring plus vibration, fine aggregate adheres better to coarse aggregate surface, and the characteristic that tumbles of coarse aggregate weakens,
Reduce in construction and tumble isolation；
7th, Vibratory Mixing is under vibration force effect, and the frictional force between material reduces, and adds flowing of the material in mixing drum
Property, material is more prone to stir in whipping process, and the reduction of frictional force can effectively reduce stirring power consumption；
8th, in the presence of stirring plus vibration, stirring eliminates traditional " seizing " phenomenon, greatly improves the running hours of machinery
Between and stability, reduce plant maintenance potential safety hazard.
2nd, asphalt Vibratory Mixing
It is well known that from states of matter, sticky thing is difficult to stir.Currently, pitch mixing both domestic and external
Material stirring is static(al) stirring, and due to the sticky nature of pitch in itself, fine aggregate and powder in compound are difficult to be evenly distributed,
Also just it is unable to reach the microcosmic uniform of storeroom；Static(al) stirring also can not allow powder and pitch fully to merge, and not become highest
The binder materials of performance；The static(al) stirring stirring intensity of itself can not allow binder materials, fine aggregate firmly to wrap in coarse aggregate
Surface, especially not ideal to some adhesivenesses raw material performance more protrudes.
Asphalt adds the asphalt in Vibratory Mixing technology, mixing drum 10 in agitating shaft using action of forced stirring
13rd, under the stirring of stirring vane 11 and mixing arm 12, compound is made to be superimposed what is produced while producing circumference, radial cyclical movement
Axial circulation is moved, and agitating shaft 13, stirring vane 11 and mixing arm 12 also generate vibration, pitch in the presence of vibrator 15
Compound is in the presence of stirring movement and vibration strength ripple, and the abundant disperse of various materials such as thick, thin, powder, uniform fusion makes
Compound reaches uniform on both macro and micro.In the presence of stirring plus vibration, what especially miberal powder and pitch had been obtained fills
Divide the high intensity binder materials for merging and foring pulpous state, while also solving " miberal powder granule " phenomenon in powder, eliminate
The rut hidden danger of pitch oil aggregation collection.Compound during colliding with each other repeatedly, pitch binder materials, fine aggregate and coarse aggregate
Between bonding it is more firm, in actual observation fine aggregate secure adhesion can be found in the surface of coarse aggregate.In practice, vibration is stirred
Asphalt natural deposited dry density after mixing accordingly is improved, and the characteristic that tumbles of coarse aggregate declines, and reduces transport, paved
The pushing phenomenon for tumbling isolation, reducing material in roller compaction process of journey, substantially increase asphalt concrete pavement rolls performance,
More preferably, surface is more attractive in appearance, also finally realizes the bulk strength and rutting resistance of asphalt concrete pavement for surface uniformity
Quality-improving.
The present invention has advantages below：
1st, this shaft vibration forced mixer realizes holoaxial Vibratory Mixing, agitating shaft 13, stirring vane 11 and stirs at work
