Description
Technical field
The present invention relates to a kind of novel disperser, particularly the Centrifugal dispersion device of a kind of middle low viscosity (50000cps is following) liquid-liquid mixing or liquid-solid mixing.
Background technology
The mixer that is widely used in the chemical industries such as cell size, glue class, coating, food, pharmacy, is mainly comprised of paddle, disperser or worm gear discrete part.Wherein planetary mixer and planet dispersator are to the mixing time of mixing of materials long (having stirred one barrel of material for general 6～8 hours), and due to the effect of just stirring and disperseing, make the material placement long period just there will be layering, depositional phenomenon, affect the result of use of subsequent handling.The planetary vacuum emulsifying device then occurring, in principle, be to address the above problem, but the emulsification parts that adopt in existing planetary vacuum emulsifying device, its rotor generally adopts centrifugal rotor structure, on its stator is, the equal opening in lower end, side has the structure (referring to Figure 19-Figure 20) of material outlet, in mixed process, material is from stator, lower end enters, centrifugal action by rotor gushes out from the side of stator, limitation due to structure, this homogenizer mixed effect is poor, in the mixed process of medium viscosity slurry, do not reach desirable effect, and incorporation time is also long.Also have existing emulsification parts not mix nanoscale material, this be because existing emulsification parts by material scattering to a certain extent after, just cannot continue to break up, and now in material, still have many aggregates to break up, therefore existing emulsification parts are poor to the mixed effect of nanoscale material.
Present patent application inventor has submitted < < worm gear disperser > > patent application in May, 2013, this worm gear disperser compared with prior art, can effectively improve mixed effect.Present patent application inventor, in practice process, has invented again a kind of chemical industry mixer Centrifugal dispersion device of better effects if.
Summary of the invention
The technical problem to be solved in the present invention is: provide a kind of mixed effect better and Centrifugal dispersion device that can hybrid nanoscale material, this Centrifugal dispersion device make material in mixed process, form compulsory radially, circumferential and axial three-dimensional hybrid flows, wherein sedimentator makes material produce powerful radial jet running up, the dispersion disc being run up is done circumferentially strong shearing and is reached efficient dispersion effect, and this Centrifugal dispersion device is in the process of running up, material also can smooth and easyly enter wherein, has improved mixed effect; Solved the undesirable problem of mixed effect existing in above-mentioned prior art.
The technical scheme solving the problems of the technologies described above is: a kind of Centrifugal dispersion device, comprise rotating shaft and be arranged at least one the Centrifugal dispersion oar in rotating shaft, each described Centrifugal dispersion oar comprises sedimentator and is connected to the dispersion disc on sedimentator, described sedimentator comprises blade, disk and axle sleeve, blade pass is crossed the disc and shaft cover and is connected, and described Centrifugal dispersion oar is arranged in rotating shaft by the axle sleeve of sedimentator.
Described dispersion disc is that peripheral intervals is provided with upwards gear piece and downwards the annulus disk-like structure of gear piece.
Described dispersion disc is that periphery is only provided with the upwards annulus disk-like structure of gear piece.
Described dispersion disc is that periphery is the annulus disk-like structure of circular arc.
The sedimentator quantity of each described Centrifugal dispersion oar is 1-5, and the quantity of disperseing disc is 1-6, disperse disc be connected to sedimentator upper end or/and lower end or/and periphery.
Further technical scheme of the present invention is: the quantity of described dispersion disc is 2-6, and adjacent two are disperseed to be also connected with 2-20 dispersion sword between disc, and described dispersion sword is that edge is the slab construction of flat or dentation.
Described dispersion disc or level are installed or are tilted to install, and disperseing disc and horizontal angle α is 0-15o.
More further technical scheme of the present invention is: described dispersion disc is connected to the periphery of sedimentator, described sedimentator top and bottom are also connected with circular housing, described housing or level are installed or are tilted to install, and housing and horizontal angle β are 0-15o.
The blade circumferencial direction of described sedimentator is involute blade or arc shaped blade or plate shaped blade, the blade axial shape of described sedimentator or skewed or circular arc or inverted V-shaped.
Described sedimentator is provided with 2-20 blade, and the quantity that Centrifugal dispersion oar is installed in described rotating shaft is 2-4.
Owing to adopting said structure, the present invention's Centrifugal dispersion utensil has following beneficial effect:
1, the present invention's Centrifugal dispersion device make material in mixed process, form compulsory radially, circumferential and axial three-dimensional hybrid flows, wherein sedimentator makes material produce powerful radial jet running up, and the dispersion disc being run up is done circumferentially strong shearing and reached efficient dispersion effect.Being particularly suitable for middle low viscosity (50000cps is following) liquid-liquid mixes or liquid-solid mixing.Adopt this disperser to there is mixing efficiency as the equipment disperseing high, can effectively prevent the advantages such as the phenomenon of powder ball in use appears in material, and stabilization of equipment performance is good.The present invention compares with existing disperser, is uniformly mixed efficiency and improves more than 50%.
2, the present invention compares with the worm gear disperser of application before the inventor, is uniformly mixed efficiency and improves more than 20%.This is because wormwheel blade and the worm gear main body of worm gear disperser are contour, during High Rotation Speed, can hinder to a certain extent material flows in worm gear disperser, and be to be connected by disk between the sedimentator blade of Centrifugal dispersion device of the present invention and axle sleeve, disk is a thin circular ring structure, between the blade of Centrifugal dispersion device and axle sleeve, form like this cavity, even when High Rotation Speed, material also from then in cavity in smooth and easy inflow Centrifugal dispersion device of the present invention, makes the incorporation time of material shorter more even.The present invention also can play good effect to the mixing of nanoscale material, the aggregate that cannot break up existing dispersion and emulsification parts, and the present invention can continue to break up.
