The twin screw multi-layer blade knife blender provides a blender which can be applied to a material system with different viscosities, in particular to the material system which has larger viscosity change scope in a short time.
Description
Technical field
The utility model relates to a kind of agitator, specifically a kind ofly can be applicable to different viscosities material system simultaneously, especially is applicable to the double helical ribbon multi-layer oar blade scraping cutter type stirrer of the big material of spread of viscosity at short notice.
Background technology
Agitator is widely used in industrial circles such as oil, chemical industry, food, light industry, pharmacy.Under the agitator effect, the material in gas-liquid, liquid liquid, the system such as liquid-solid disperses mutually, evenly mixes, and has strengthened mass transfer, heat transfer, and its chemical reaction process is strengthened.According to different material characteristics and stirring purpose, the type of the agitator of use also has nothing in common with each other, and mainly contains: dasher, impeller-type stirrer and anchor formula and gate stirrer etc.
For the stirring of high-viscosity material, whether the moulding of agitator and design be rationally most important.Experience was in the laminar region operation in the past, selected frame or the anchor agitator of diameter near the still wall for use, or helix(ribbon type) agitator; Adopt nearly center multilayer hinged joint oar formula or helix(ribbon type) agitator and outer rim anchor agitator to be used in combination to pseudoplastic fluid.But in these two kinds of methods, the former mixing effect is not good enough, and latter's structure is more complicated then.In addition, high-viscosity material occurs stirring the dead band in whipping process easily, and is easy to pile up material on the stirred tank wall.In order to overcome above-mentioned defective, Chinese patent CN2429251Y has designed a kind of plate and frame agitator that sticky material stirs that is used for, and this patent has realized that the systemic circulation of fluid is mobile, and mixed performance is better, but does not have fine solution material to be attached to the sidewall of reactor problem.Though Chinese patent CN2738875Y and CN2430211Y have solved the attached wall problem of material, the agitator structure of Chinese patent CN2738875Y design is too complicated, does not utilize the maintenance and the regular maintenance of agitator, and the equipment investment cost costliness; And Chinese patent CN2430211Y is a kind of scraped wall agitator, and is relatively simple for structure, is suitable for the mixing that density differs bigger two phase materials, but owing to be provided with lacing wire between agitator frame and the scraper plate, causes it not to be suitable for the mixing of high-viscosity material.
Summary of the invention
The purpose of this utility model is the problem and shortage that solves in the background technology, provides a kind of and can be applicable to low viscosity material, high-viscosity material and the double helical ribbon multi-layer oar blade scraping cutter type stirrer of the big material system of spread of viscosity at short notice simultaneously.
The purpose of this utility model is to realize like this, it is made up of shaft, ribbon, support blade, independent blade and flexible scraper, it is characterized in that supporting blade and independent blade respectively symmetry be installed on the shaft, with the angle of inclination beta that supports blade and independent blade and radial level cross section in one deck blade is 10 °-45 °, ribbon is connected with shaft by supporting blade, flexible scraper divides the two sections symmetry to be fixed on the ribbon top, and flexible scraper and still wall angle α are 20 °-60 °.
The material system of adding certain viscosity in the stirred tank, startup drive apparatus drive shaft and are installed in the independent blade on the shaft, the ribbon rotation of supporting blade and being attached thereto by the support blade.Material is realized evenly mixing under independent blade, support blade and the dual stirring of ribbon.The flexible scraper on ribbon top when rotated, the sticky material that can in time efficiently the still wall be adhered to is wiped off, thoroughly solves sticky material and is attached to the uneven problem of mixing that the still wall causes.
The utility model compared with prior art has the following advantages:
1. the utility model can be realized the stirring to various viscosity material systems, especially is applicable to the material system that spread of viscosity is bigger at short notice;
2. blade structural design of the present utility model is mixed the radial circulation stream of material and is reinforced, the ribbon structural design then makes the axial circular flow of material mix and is strengthened, the two combines, and can guarantee that material can both reach excellent mixed effect at stirred tank center and limit wall;
3. the ribbon structure in the utility model plays the effect of baffle plate simultaneously again, and " the cylindric tow-away zone " that can eliminate reactor central authorities under the turbulence state makes mixed flow realize that under shearing, pulverizing, dispersion and twisting effect material fully mixes;
4. blade structural design of the present utility model can guarantee effectively to avoid when liquid-liquid system mixes liquid-liquid to separate, and makes the reactor temperature uniformity; When liquid-solid system is mixed, can prevent the solid sedimentation again;
5. the multi-layer oar blade topology layout in the utility model except the radial circulation stream that ensures material mixes, can also promote the axial circular flow of ribbon to mix;
6. the support blade in the utility model links together ribbon and shaft, and the company's of playing muscle and reinforcement effect make whole agitator structure design compacter;
7. the angle of inclination beta that supports blade and independent blade and radial level cross section is 10 °-45 °, and the loss of useful work can be effectively reduced at less inclination angle, reduces the operating cost of equipment;
8. flexible scraper can in time scrape the stirred tank wall, thoroughly solves sticky material and is attached to the uneven problem of mixing that the still wall causes, in the time of can avoiding scraper to scrape the still wall simultaneously, to the damage of still wall.
