Abstract
The utility model relates to a short flow type micro powder whirlwind sorter, which comprises a whirlwind barrel of which the lower end is provided with a discharge valve. The lower end of an eduction pipe of the whirlwind barrel is provided with a short circuit preventing cover, and boiling rings and short flow trays are arranged in the whirlwind barrel. The utility model has the advantages of centralized distribution of size grading, high production efficiency and low cost and is suitable for grading powder materials of which the granularity is below 5 microns.
Description
The utility model relates to solid material is diffused in the equipment technical field of carrying out sorting in the air-flow.
The existing equipment that utilizes air-flow powder to be carried out classification, for example the patent No. is three air intake powder pneumatic classification machines of 91229653.4, the defective of ubiquity partition size wider range, for the concentrated powder product of size distribution that needs in producing, be difficult to guarantee the classification quality, influence the result of use of micro mist.For the classification of the micro mist that requires size distribution to concentrate, mostly adopt the liquid sedimentation at present, this method not only technological process is long, inefficiency, and the production cost height, and can't classification to the micro mist of particle diameter below 5 microns.
The purpose of this utility model is exactly that a kind of more concentrated micro mist cyclone classifier of micro mist size distribution that classification is obtained will be provided, and can substitute the liquid classification of sedimentation, can be fit to the classification of particle diameter micro mist below 5 microns again.
The technical solution of the utility model is: it comprises a whirlwind tube and is installed in the discharge valve of whirlwind tube lower end, in the outside, escape pipe lower end, whirlwind tube top an anti-short circuit cover is installed, below anti-short circuit cover, the boiling ring that is installed on the whirlwind tube inwall is arranged, below the boiling ring, outer rim and whirlwind tube inwall short flow table at regular intervals are installed.
The utility model has the advantages that: compare with existing powder air current classifying equipment, size distribution is concentrated after the classification, for the required micro mist of Abrasive Industry, can substitute the liquid staging fully, meet and exceed the GB2477-83 standard, and can be used for the classification of particle diameter micro mist below 5 microns.For example: for granularity W
10Classification, the weight of the basic grain of 10-7 micrometer range reaches 49.5%, the weight of 10-5 micrometer range mangcorn can reach 79.1%, 14-10 micrometer range coarse grain weight is zero less than coarse grain weight more than 10%, 20 micron; For the classification of granularity below 1.5 microns, the basic grain of 1.5-1.0 micrometer range weight reaches 70.9%, and 1.5-0.5 micron mangcorn weight can reach 96%, 2-1.5 micron coarse grain weight 2.7%.In a word, the utility model classification quality is good, the production efficiency height, and cost is low.
Accompanying drawing shows concrete structure of the present utility model, wherein:
Fig. 1 is a longitudinal section wherein, shows its overall structure;
Fig. 2 is the A-A cutaway view among Fig. 1.
In the embodiment that accompanying drawing provides, discharge valve (8) is equipped with in the lower end of whirlwind tube (2), the outside in the lower end of the escape pipe (9) at whirlwind tube (2) top, utilization is marked closely screw (1) an anti-short circuit cover (3) of adjustable up and down umbrella shape is installed, have in the below of anti-short circuit cover (3) be installed in whirlwind tube (2) but cross sectional shape on the inwall is circular up-down adjustment boiling ring (4), have by four supports (6) in the below of boiling ring (4) and mark closely that screw (7) is installed in whirlwind tube (2) but its outward flange on the inwall and whirlwind tube inwall is at regular intervals and the short flow table of up-down adjustment (5).
Operation principle of the present utility model is: air-flow also rotation operation downwards at a high speed in the inlet a of air inlet pipe (10) enters whirlwind tube (2) of carrying micron particles, under centrifugal action, be split into skin than coarse granule, and at the bottom of falling to along wall tin, certainly collect mouthful b by discharge valve (8) and discharge collection, whirlwind tube middle part is together stoped by short flow table (5) than fine grained and descending air-flow, and the gas outlet c that passes through in the rotation is discharged to next stage.The effect of anti-short circuit cover (3) is to prevent from not to be separated to directly entering blast pipe (9) lower end than coarse granule and discharging of layering.The effect of boiling ring (4) is to shift to the middle part after being separated to upspringing than fine grained that skin goes, together discharges with air-flow.The utility model is realized the classification requirement of different grain size distribution by to preventing that short circuit cover, boiling encircle and the adjustment up and down of short flow table installation site, but and several series connection uses.
Claims (3)
1, a kind of short streaming micro mist cyclone classifier, comprise a whirlwind tube (2) and be installed in the discharge valve (8) of whirlwind tube (2) lower end, it is characterized in that: the outside, lower end at the escape pipe (9) on whirlwind tube (2) top is equipped with an anti-short circuit cover (3), there is the boiling ring (4) that is installed on whirlwind tube (2) inwall below at anti-short circuit cover (3), and the short flow table (5) that outward flange and whirlwind tube (2) inwall have a spacing is installed in boiling ring (4) below.
2, short streaming micro mist cyclone classifier according to claim 1, it is characterized in that anti-short circuit cover (3), boiling ring (4) and short flow table (5) but the equal up-down adjustment in position.
3, short streaming micro mist cyclone classifier according to claim 1 is characterized in that anti-short circuit cover (3) is umbrella shape.
