Description
Technical field
This utility model belongs to extension facility technical field, is specifically related to a kind of centrifugal classifying.
Background technology
Progressively modernization along with China's industry, all trades and professions are more and more higher to the requirement of powder material granularity, have been enter into micron even submicron order. and the most increasing to the demand of high fineness powder body in industries such as grain, feedstuff, building materials, solid beverage, colo(u)r-in-oil, medicine.Therefore, powder material is carried out crushing and classification deep processing again the most necessary.
Particle classifying is that the suffered gravity in fluid (such as water and air) of the granule according to different grain size, shape and proportion is different with resistance of medium, thus has different terminal velocity degree and carry out.Classification is gas or liquid point dry and wet according to fluid used；It is gravity or centrifugal force is divided into gravity classification and centrifugal classification by active force.Cross by granule motion or fluid relative flowing misclassification flow point level and counter-current fractionation.Owing to centrifugal force decades of times even hundreds of times are more than gravity, the classification majority of subparticle uses centrifugal force to carry out.At present, commonly use in powder body deep process technology is dry method centrifugal flow classification, i.e. uses centrifugal classifying that powder body is carried out classification.
Same, centrifugal classifying have also been obtained at Grain Trade and is widely applied.After to wheat milling gained flour by grading during the chemical constitution study of each ingredient, it is found that: flour (particle size range 1～200 μm) is mainly made up of starch granules, big endosperm agglomerate and matrix debris three part, and different size of flour particle is made up of different starch and protein.Wherein, 1～17 μm flour are made up of the starch granule dissociated and free proteose matter, and protein content is higher, 2 times of the most former flour average protein content；17～40 μm flour are mainly made up of big starch granules, and protein content is the lowest, are equivalent to the half of former flour average protein content；Mainly being made up of big endosperm agglomerate more than the flour of 40 μm, protein content is suitable with flour, by centrifugal classifying, flour is carried out deep processing, can extract the product of the different multiple use of protein content from flour.Although traditional centrifugal classifying is capable of the classification of flour; but centrifugal classifying usually can temperature be higher because of for a long time work in classification process; this will certainly affect the quality of flour, easily causes quality fluctuation, even causes the rotten of protein in flour.Therefore, research and develop a kind of novel centrifugal classifying, the classification of powder body can not only be realized, moreover it is possible to according to monitoring temperature, centrifugal classifying inside is carried out cooling process, to avoid the rising of temperature to cause the change of powder body or rotten, such a centrifugal classifying is bound to be favored by market.
Number of patent application 201210580140.1 discloses a kind of centrifugal classifying, including body, the charging mouth of pipe, discharge nozzle and sand removing hole, removal device, impeller, air inlet, cover, motor, end cap and rotating shaft, it is characterized in that: end cap seal is passed through on the top of body, the hollow cavity upper end of body interior is fixed with separation hood, separation hood is connected with one end of discharge nozzle, the other end of discharge nozzle extends to external, and body side is further fixed on feed pipe；Body upper part is fixed with motor, and motor is connected by rotating shaft transmission has impeller, rotating shaft to extend to body interior and coaxial with body, impeller is placed in separation hood lower end, is socketed with sleeve outside rotating shaft, and sleeve is positioned on the sidewall of separation hood and has air inlet；Body bottom portion connects removal device, and removal device lower end connects sand removing hole.This invention is capable of classification and the classification efficiency height of different-grain diameter, but, this invention can not monitor the temperature within centrifugal classifying in real time, more can not carry out cooling and process to avoid the rising of temperature to cause the change of powder body or rotten.
Utility model content
In view of this, the purpose of this utility model is for the deficiencies in the prior art, it is provided that a kind of centrifugal classifying, can not only realize the classification of powder body, according to monitoring temperature, centrifugal classifying inside can also be carried out cooling process, to avoid the rising of temperature to cause the change of powder body or rotten.
For reaching above-mentioned purpose, this utility model by the following technical solutions:
A kind of centrifugal classifying, including top be cylindrical lower portion be cone outer cylinder body and inner barrel, described inner barrel is sleeved on described outer cylinder body, described inner barrel lower end arranges coarse powder outlet, described outer cylinder body is stretched out in the outlet of described coarse powder, described outer cylinder body upper end arranges end cap, in the middle part of described end cap, rotating shaft is set, described inner barrel is stretched in described rotating shaft bottom, described rotating shaft top is stretched out described end cap and is connected with motor, big blade from top to bottom it is respectively provided with in described rotating shaft, little fan blade and dispersion impeller, the diameter of described little fan blade is less than the diameter of described big blade, the diameter of described dispersion impeller is less than the diameter of described little fan blade；Arranging cold air air inlet, charging hole and some classification air inlets on described end cap, described cold air air inlet is connected by pipeline refrigeration machine, and described refrigeration machine is for the cooling within grader, and described charging hole is used for loading material to be fractionated；Described inner barrel inwall arranges temperature sensor, for detecting the temperature within grader；Arranging removal device bottom described outer cylinder body, described removal device lower end connects fine powder outlet.
Described rotating shaft lower end arranges fixing fan blade, and described fixing fan blade produces buoyancy upwards to be separated by fine powder a small amount of in coarse powder.
