Detailed description of the invention
Technical solution adopted in the utility model and effect thereof are expanded on further below in conjunction with embodiment and accompanying drawing.
Embodiment
In conjunction with accompanying drawing 1, the blender of this utility model a kind of use for laboratory chemical industry filter-press residues compound is:
The blender of a kind of use for laboratory chemical industry filter-press residues compound, including base 1, elevating mechanism 2, rabbling mechanism 3 and vibrating mechanism 4, described elevating mechanism 2 and vibrating mechanism 4 are arranged on base 1, and rabbling mechanism 3 is fixed on elevating mechanism 2 upper end.Power is passed to the main shaft 13 in transmission case 14 by shaft coupling 11 and slows down by described two-speed motor 10；Described main shaft 13 drives the paddle 19 being fixed on eccentric mounting 16 to revolve round the sun, and paddle 19 completes rotation by the planetary gear 17 of stirring rachis 18 upper end around fixing internal gear 15 simultaneously.The table top 22 of described vibrating mechanism 4 and agitated kettle 20 are by eccentric grove 21 rotational lock；The table top 22 of described vibrating mechanism 4 is placed in the upper surface of four springs 23, and the hex nut 25 and montant 24 by spring 23 lower end constitutes vertical elasticity and be connected with base 1；Described table top 22 bottom is equipped with the double output shaft electric machine 27 in two ends, and its two ends shaft is respectively provided with the wheel 28 that shakes of two groups of identical band oscillators 29, produces exciting force and carrys out vibration table 22；Described screw-threaded shaft elevator 5 is controlled by motor 9, is co-located in protective cover 8 with the pillar 6 being connected on support 7.
Under the concrete structure of the blender of above-mentioned a kind of use for laboratory chemical industry filter-press residues compound is supported; the materials such as chemical industry filter-press residues are added in agitated kettle 20; agitated kettle 20 is passed through eccentric grove 21 rotational lock on the table top 22 of vibrating mechanism 4; open the control switch of screw-threaded shaft elevator 5 outside protective cover 8; the paddle 19 of rabbling mechanism 3 is fallen into specific bit in agitated kettle 20 put; open the control switch controlling rabbling mechanism outside switch and transmission-case cover 12 of window cover 30 outboard vibrations mechanism 4 again, select low rate mixing.It is found that the viscosity of compound significantly declines, mobility increases, and clustering phenomena significantly reduces, and substantially improves the micro-property of mixture particle, quickly realizes the target of all homogenizing on compound both macro and micro.
The operation principle of this device is:
(1) vibrate, stir coefficient selection
Applying vibration while stirring, mixture particle is constantly caused vibration by the effect of impulsive force.This vibration makes the physico-mechanical properties of compound play change.First, thixotropic transformation makes generated colloid be colloidal sol by gel conversion, next to that the contact point of granule is unclamped by vibration source institute work, thus destroy intergranular cohesive force produced by micro-pipe pressure, and the mechanical interlocking produced owing to granule directly contacts, this just makes internal resistance be substantially reduced, and finally makes compound partly or entirely liquefy, and has the character close to heavy liquid.
The thixotropy efficiency of compound, the structural viscosity being had after liquefying with it is weighed.During friction effect, the viscosity of compound can represent such as formula (1):
In formula, the shear stress of τ compound,
τ0The 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 ultimate shearing stress τ of compound0In certain limit velocity VThe limitBeing the function of speed in the past, exceeding this is then constant, and this constant value typically goes to zero, as formula (2) and (3) represent:
τ0=f (V) (V < VThe limit) (2)
τ0=K ≈ 0 (V >=VThe limit) (3)
In formula, τ0The ultimate shearing stress of compound,
The vibration velocity of V compound,
VThe limitThe vibration mark speed of compound,
The function of f (V) speed,
K constant.
It follows that when the movement velocity of compound major part granule is both greater than VThe limitTime, the most whole system is close to liquefying completely.Therefore, when vibration is acted on chemical industry filter-press residues compound with stirring by experiment jointly, under effect of vibration, the yield shear stress of compound is almost nil, i.e. the viscosity of compound reduces, and stirring efficiency significantly improves.
(2) selection of blender vibrating mechanism
Mixing plant of the present utility model uses vibration table to apply exciting force for compound, vibration table contacts with the agitated kettle bottom surface equipped with compound, theoretic wave source is each numerous points on this contact surface, the wave surface of each ripple produced by every is hemisphere face, but because wave source is countless, according to Huygen's principle, wave group is laterally interfering or is offsetting, only to a direction Free propagation, i.e. upwardly propagating, the wave surface of this wave group should be the plane parallel with contact surface.Vibration wave is propagated in compound, and by the damping action of compound, the waste of energy is directly proportional to the thickness of propagation layer.
(3) parameter of blender vibrating mechanism selects
The parameter of vibration table mainly has frequency of vibration, amplitude, vibration duration etc..Numerical value for compound, amplitude and frequency should select can coordinate mutually, makes granule vibration decay little, and will not occur resting state in vibration processes.This utility model selects the amplitude of vibration table to be 0.75 ± 0.05mm, when itself and blender act on compound jointly, its homogenization degree can be made to strengthen.The frequency of the forced vibration such as natural frequency close to mixture particle, then produce resonance, and at this moment decay minimum, and amplitude is up to maximum.But granule grade is a lot of in compound, it is impossible to apply such multi-frequency, a frequency can only be used with certain particle size range.Therefore, the grade that experiment often has according to actual compound, and set amplitude, the frequency of vibration of selection is 2800-3000 beat/min.The amplitude that too high frequency is arranged in pairs or groups is less, it is impossible to making the abundant effect vibrated of the material in agitated kettle, effect is undesirable.Still further aspect, too high frequency of vibration influences whether the life-span of whole Vibratory Mixing equipment, improves use cost.
The above; for the person of ordinary skill of the art; can conceive according to the technical solution of the utility model and technology and make other various corresponding changes and deformation, and all these change and deformation all should belong to this utility model scope of the claims.
