Description

Liquid liquid rapid mixing dissolver

The utility model relates to the mixing arrangement of solution, specifically a kind ofly can make two kinds of indissoluble materials rapidly-soluble device under the effect of high speed rotational shear.

Liquid liquid mixed dissolution has following several form usually: liquid and liquid can dissolve mutually fast, and liquid and liquid can not dissolve mutually, and liquid and liquid are separated etc. three kinds than indissoluble mutually.Wherein liquid and liquid can dissolve mutually fast, realize industrial mixing than being easier to; Liquid and liquid do not dissolve mutually, and the general method that adds solvent or emulsifying agent that adopts is made cream frost, food service industry manufacturing emulsification goods as cosmetic industry and pharmaceuticals industry, and oil phase and water all add emulsifying agent with liquid form and mix.For making emulsion stable, method in the past is to adopt common stirring, as paddle agitator, turbine stirrer, propeller agitator and anchor agitator etc.The cream frost that these methods make, the particle of decentralized photo is very big, because they only are to mix, does not have strong shearing, centrifugal, so be not suitable for the stable product of the quality of production.In recent years, along with the continuous development of stirring technique, most of enterprises adopt homogenizer or high speed dispersor to carry out emulsification.At present, homogenizer both domestic and external or high speed dispersor operation principle are to utilize a high speed rotor rotated to cooperate with closely spaced with the stator of fixing, the rotor rotation produces certain centrifugal force, forming vacuum makes material suck automatically from an end, simultaneously, centrifugal force radially moves material, discharges by the hole on the stator.Because rotor and stator gap are less, a part of material is sheared therein or is milled, and most of fluids directly circulate by the hole of stator, move certain hour like this and can obtain better products.But these structures are because an endfeed, and the hole discharging of stator side, and the sectional area in aperture is bigger has bigger restricted; Shearing is greatly then milled little, milling, it is little greatly then to shear, and not feeding section, the flux of milling is little, and 3, the more insoluble situation of liquid liquid, such as in the obtaining liq washing agent, the dissolving of AES (fatty alcohol polyoxyethylene ether sulfate) and water, adopted in the past and under hot water conditions, do not stop to stir, could dissolve for a long time thoroughly, so not only wasted energy but also spended time.

The purpose of this utility model is a kind of liquid liquid rapid mixing dissolver of design, with raising mixing efficiency and speed, and the quality of product.

Its main technical schemes comprises that one is installed in the rotor in the stator, charging aperture is arranged on stator and be distributed in the tap of stator sidewall, blade is arranged on rotor, it is characterized in that the charging aperture on the stator has two, one of them is the charging hole that is positioned at bottom center, another is the feed pipe that is installed in above the stator, the outlet of this feed pipe points to stator central authorities, the curve in the blade outside is three sections distributions, be followed successively by the feeding section from the leading edge of blade backward, the section of milling and shearing section, the curve and the V-shaped angle of stator inner surface of wherein feeding section, the section of milling curve is corresponding with table curve in the stator, and indent transition in its back-end, form the edge of a knife with the front end of shearing section, it is identical with the stator inner surface curve to shear the section curve; The cylindrical of blade inlet edge and its wheel hub is tangent, and tap aperture uniform on the stator wall is 1～5 millimeter, utilizes flange to connect loam cake on decided, and the axle that is fastenedly connected with the impeller of blade utilizes axle sleeve to be installed in the central authorities of loam cake.

The utility model has the advantages that because two charging apertures are arranged, the top material is because of deadweight and negative pressure is very easy enters, the bottom material also can be by last suction, discharge by the tap on the stator then, form the circulation of two brute forces, do not have the dead angle, saved dissolving or emulsification times, secondly, because the feedstock direction of feed pipe is aimed at the center of rotor or stator, charging aperture is positioned at the center in stator cross section, thereby, guaranteed charging rate, avoid owing to lacking the vacuum that material produces, and this vacuum can cause cavitation phenomenons that noise is very big, the power surge, thus normal running destroyed.The 3rd, along the special feeding section of direction of rotation, make fluid enter the gap between rotor and stator better at the blade inlet edge of rotor, after fluid enters the gap, mill through the section of milling earlier, the section of milling shape and stator profile are consistent, and guarantee evenly, then, fluid meets the mechanical shear segment through the transition of a bit of indent, and the effect of indent mainly is in order to form the edge of a knife, to make the shearing section have a comparatively sharp head, fluid is mechanically sheared, thereby obtained better effect.The 4th, less aperture has crucial characteristics on the stator sidewall, especially during the more insoluble material of lysate liquid, has increased both mass transfer areas, avoid solute to discharge simultaneously from stator after coalescence or agglomerating phenomenon again.The compound that utilized this device for mechanical dissolving AES or high score reaches the level of continuous feed dissolving, and very superior, the special pearl structure of rotor makes device generally be applicable to the dissolving of liquid liquid rapid mixing in addition, and the dispersion particle diameter that guarantees emulsion is at 1～2 μ m.
