Embodiment
The technical solution used in the present invention and its effect is expanded on further with reference to embodiment and accompanying drawing.
Embodiment
With reference to accompanying drawing 1, a kind of mixer of use for laboratory chemical industry press filtration dregs mixing material of the present invention is：
A kind of mixer of use for laboratory chemical industry press filtration dregs mixing material, including base 1, elevating mechanism 2, stirring
Mechanism 3 and vibrating mechanism 4, described elevating mechanism 2 and vibrating mechanism 4 are arranged on base 1, mixer
Structure 3 is fixed on the upper end of elevating mechanism 2.Power is transmitted to by described two-speed motor 10 by shaft coupling 11
Move the main shaft 13 in case 14 and slow down；Described main shaft 13 drives the paddle being fixed on eccentric mounting 16
19 are revolved round the sun, while paddle 19 is by stirring the planetary gear 17 of the upper end of rachis 18 in fixation
Gear 15 completes rotation.The table top 22 of described vibrating mechanism 4 is rotated with agitated kettle 20 by eccentric grove 21
Locking；The table top 22 of described vibrating mechanism 4 is placed in the upper surface of four springs 23, and passes through spring
The hex nut 25 and montant 24 of 23 lower ends form vertical elastic connection with base 1；Described table top 22
Bottom is respectively provided with two groups of identicals with oscillator 29 equipped with the double output shaft electric machines 27 in a both ends, its both ends shaft
Shake wheel 28, produces exciting force and carrys out vibration table 22；Described screw-threaded shaft elevator 5 is controlled by motor 9, with connecting
The pillar 6 being connected on support 7 is co-located in protective cover 8.
In the case where a kind of concrete structure of above-mentioned mixer of use for laboratory chemical industry press filtration dregs mixing material is supported, to stirring
The materials such as chemical industry filter-press residues are added in pot 20, by agitated kettle 20 by the rotational lock of eccentric grove 21 in bobbing machine
On the table top 22 of structure 4, the controlling switch of the outside screw-threaded shaft elevator 5 of protective cover 8 is opened, by rabbling mechanism 3
Paddle 19 fall into specified location in agitated kettle 20, then open the control of the outboard vibrations mechanism 4 of window cover 30
The controlling switch of switch and the outside rabbling mechanism of transmission-case cover 12, selection mix slowly.It can be found that mixing
The viscosity of material significantly declines, and mobility increase, clustering phenomena significantly reduces, and substantially improves mixture particle
Micro-property, quickly realize on compound both macro and micro all targets of homogeneous.
The operation principle of the device is：
(1) vibrate, stir coefficient selection
Apply vibration while stirring, mixture particle is constantly caused vibration by the effect of impulsive force.This
Kind vibration makes the physico-mechanical properties of compound play change.First, thixotropic transformation makes generated colloid by coagulating
Glue is converted into colloidal sol, next to that vibration source institute's work unclamps the contact point of particle, so as to destroy due to micro-pipe
Intergranular cohesive force caused by pressure, and because particle directly contacts and caused mechanical interlocking, this
Internal resistance just is substantially reduced, finally compound is partly or entirely liquefied, is had close to heavy liquid
Property.
The thixotropy efficiency of compound, weighed with possessed structural viscosity after its liquefaction.Effect without friction
When, the viscosity of compound can represent such as formula (1)：
In formula, the shear stress of τ --- compound,
τ0--- the ultimate shearing stress of compound,
The shear viscosity of η --- compound,
--- the normal velocity gradient in perpendicular flow direction.
Experiment experience is, it is known that the ultimate shearing stress τ of compound0In some limit velocity VThe limitIt is in the past speed
Function, it is then constant to exceed this, and this constant value typically goes to zero, as formula (2) and (3) represent：
τ0=f (V) (V<VThe limit) (2)
τ0(V >=the V of=K ≈ 0The limit) (3)
In formula, τ0--- the ultimate shearing stress of compound,
The vibration velocity of V --- compound,
VThe limit--- the vibration mark speed of compound,
F (V) --- the function of speed,
K --- constant.
It follows that when the movement velocity of compound major part particle is both greater than VThe limitWhen, then whole system connects
It is bordering on complete liquefaction.Therefore, experiment will be vibrated with stirring collective effect when chemical industry press filtration dregs mixing material, shake
Action is almost nil with the yield shear stress of lower compound, i.e., the viscosity reduction of compound, stirring efficiency substantially carry
It is high.
(2) selection of mixer vibrating mechanism
The mixing plant of the present invention uses shake table, and to apply exciting force for compound, shake table is with being equipped with compound
The contact of agitated kettle bottom surface, theoretic wave source is each numerous points on the contact surface, each caused by every
The wave surface of ripple is hemisphere face, but because wave source is countless, according to Huygen's principle, wave group is laterally mutual
Interference is offset, and only to a direction Free propagation, that is, is upwardly propagated, the wave surface of the wave group should be with connecing
The parallel plane of contacting surface.Vibration wave is propagated in compound, by the damping action of compound, the loss of energy
Amount is directly proportional to the thickness of propagation layer.
(3) the parameter selection of mixer vibrating mechanism
The parameter of shake table mainly has vibration frequency, amplitude, vibration perdurabgility etc..For compound, amplitude
It should select coordinate mutually with the numerical value of frequency, make particle vibration decay small, and will not go out in vibration processes
Existing inactive state.The amplitude of present invention selection shake table is 0.75 ± 0.05mm, when it makees jointly with mixer
It during for compound, can increase its homogenization degree.The frequency of forced vibration is as close to mixture particle
Intrinsic frequency, then resonance is produced, at this moment decay is minimum, and amplitude is up to maximum.But particle grade is very in compound
It is more, it is impossible to apply such multi-frequency, can only be with certain particle size range, using a frequency.Therefore, test
The grade often being had according to actual compound, and set amplitude, the vibration frequency of selection is 2800-3000
Beat/min.The amplitude that too high frequency is arranged in pairs or groups is smaller, it is impossible to makes the material in agitated kettle fully vibrated
Effect, effect are undesirable.Still further aspect, too high vibration frequency influence whether whole Vibratory Mixing equipment
In the life-span, improve use cost.
It is described above, for the person of ordinary skill of the art, can with technique according to the invention scheme and
Technical concept makes other various corresponding changes and deformation, and all these changes and deformation should all belong to this hair
Bright scope of the claims.
