Abstract
The utility model relates to a high-shear and high circular flow type stator-rotor structure of an emulsifying machine. The stator-rotor structure consists of a stator and a rotor, and is characterized in that one to five rows of round holes are respectively arranged in the stator and the rotor, and two to five ribbed plates are also arranged in the middle of the rotor. The stator-rotor structure of the emulsifying machine integrates high shear and high circulation, and has good effects for emulsion, dispersion and mixing through evidences.
Description
Technical field
The utility model relates to the critical component of the mulser that a kind of chemical industry, food, pharmaceutical field use, and the mulser that relates in particular to a kind of high shear and high circular flow type is fixed-rotor structure.
Background technology
Emulsification process is the common a kind of unit operations of industry such as chemical industry, food, pharmacy, refer to two kinds of immiscible liquid (one of them is water always almost, and another is water-fast " oil " mutually) are transformed into the process of equally distributed liquid/liquid dispersion emulsion system.Theoretical according to emulsion stability, make the dispersion of the formation state that keeps relative stability for a long time, drop should be as far as possible little.In practical operation, drop reduces mainly to realize by mulser.The effect of mulser is to provide mechanical energy to emulsification procedure, make one be blended into mutually another mutually among, the distortion by thick drop and breaking constantly reduces so that finally finish emulsion process the diameter of thick drop.Emulsification machinery commonly used has: mixer, high pressure homogenizer, ultrasonic emulsification machine, colloid mill and fixed-rotor mulser etc.Mixer usually can only be as thick emulsifying device; Not only energy consumption is larger for high pressure homogenizer and ultrasonic emulsification machine, and the function of mixing is relatively poor, and is good not with the product homogeneity of their emulsification; Colloid mill strictly says and belongs to fixed-rotor-support-foundation system, and shortcoming is that the time of staying of emulsion in annular space is short, generally will be through circulating emulsion repeatedly, or with the operation that is together in series of several colloid mills; Fixed-rotor-type mulser is owing to have the function of self-loopa, overcome the deficiency of colloid mill, generally operate with intermittent mode, as long as give the regular hour, just can guarantee all fully emulsification of material in the whole container, thereby emulsify well, in practical operation, obtain using more widely, mulser is fixed-rotor structure typically, can be divided into two classes: circular form and shearing-type.Exist on the market now various fixed-rotor structure, flow and shear often conflict, for certain input power, the circular flow that certain structures produces is large, and the shearing force less, circular form belongs to this type of usually; The shearing force that other structures then produce is larger, and the circular flow less, shearing-type belongs to this type of usually.For the dispersion that requires without change of granularity, married operation, can select the circular form structure, because circular form has higher mixing intensity, but within a short period of time, each phase materials is mixed, supply with the power that is enough to make the liquid particles fragmentation when the emulsification job requirements, angle from breakage of particles, multi-layer Shear-type is better, but from improving production capacity, shorten emulsification times and consider, wish that again liquid can constantly pass in and out the gap between fixed-rotor, be that circular flow is the bigger the better, for the dispersion that has change of granularity to require, married operation requires to select all larger structures of circular flow and shearing force, and this type of emulsification operation is for emulsification, the operations such as dispersion and mixing, circular flow and shearing force that fixed-rotor structure produces all should be the bigger the better, but existing structure still difficulty satisfy this requirement.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides deciding-rotor structure of a kind of mulser, combines high shear and high circulation, and evidence is used for emulsification, dispersion and mixing, all has good effect.
The problem that exists for solving prior art, the technical scheme that the utility model is taked is: the mulser of a kind of high shear and high circular flow type is decided-rotor structure, consisted of by stator and rotor, it is characterized in that: described stator and rotor are equipped with 1-5 row circular hole, also are provided with 2-5 piece gusset in the middle of the described rotor.
Described fixed-gap between the rotor is 0.1-0.3mm, relative velocity is 2800-3500r/min.
Described stator and rotor are provided with 3 row's circular holes, are provided with 3 gussets in the middle of the described rotor.
Described in the utility model fixed-rotor structure, gusset in the middle of the rotor rotates in company with rotor, drive fluid and produce high turbulence, gap between stator and the rotor is very little, and relative velocity is very high, so this gap becomes height laminar flow shear zone, and rotor is provided with several rows of circular hole, by the quantity of perforate on control stator and the rotor and the size in aperture, size that can the controlled circulation flow.Described in the utility model fixed-rotor structure combines high shear and high circulation, evidence is used for emulsification, dispersion and mixing, all has good effect.
Description of drawings
Fig. 1 be the utility model fixed-structural scheme of mechanism of rotor;
1 rotor, 2 stators, 3 gussets, 4 wheel hubs, 5 circular holes.
The specific embodiment
A kind of high shear as Figure 1-3 and the mulser of high circular flow type are decided-rotor structure, are made of stator and rotor, and wherein, stator and rotor are equipped with 1 row's circular hole, in order to the size of controlled circulation flow; Also be provided with 3 gussets in the middle of the rotor, rotate in company with rotor, drive fluid and produce high turbulence; Gap between fixed-rotor is 0.2mm, and relative velocity is 3000r/min, and this gap becomes height laminar flow shear zone.With this device fabrication soymilk, add a certain amount of monoglyceride, feed size 80 orders only need 30 min, can make in the whole container soymilk fully, fully emulsifying, the soymilk that obtains is fine and smooth, without granular sensation, repeatedly granularity≤5 L m is examined under a microscope in sampling, and emulsion-stabilizing, without lamination.Experiment confirm, described in the utility model fixed-rotor structure combines high shear and high circulation, evidence is used for emulsification, dispersion and mixing, all has good effect.
More than the utility model has been done detailed description, but the utility model is not limited to the above embodiments.All equivalences of doing according to Spirit Essence of the present utility model change or modify, and all should be encompassed in the protection domain of the present utility model.
