Abstract
The present invention relates to solid powder classifying equipoment technical field more particularly to a kind of more grade vertical air flow graders.More grade vertical air flow graders include body and the multiple rotors erected on body, rotor includes blade, the rotor is divided into more than two, the impeller clearance of different group rotors and/or rotating speed are different, to penetrate varigrained product, the product of same particle sizes is penetrated per group rotor, and is connected with same discharge nozzle.In gas flow sizing machine, rotor is divided into according to the difference of impeller clearance and/or rotating speed more than two, same discharge nozzle is connected with per group rotor, the impeller clearance of different group rotors and/or rotating speed are different, it is different through the granularity of the product of rotor, a variety of grade products can be obtained simultaneously.
Description
Technical field
The present invention relates to solid powder classifying equipoment technical field more particularly to a kind of more grade vertical air flow graders.
Background technology
Gas flow sizing machine play the role of in the grinding system of mine and cement industry it is very important, with air current classifying
Machine has developed to the rotator type air-flow point of the third generation after the cyclonic airflow grader of the centrifugal and second generation of the first generation
Grade machine, in recent years rotator type gas flow sizing machine be widely used in mine and cement industry.
Notification number is CN203842820U, the day for announcing is that in September, 2014 Chinese patent document of 24 days discloses a kind of stand
Formula gas flow sizing machine, the multiple rotors erected including body and on body, rotor include blade, the upper end of all rotors and one
A total discharge port is connected, and subparticle goes out mill from total discharge port, and it is single that this gas flow sizing machine has obtained product grade
Problem.
Invention content
The purpose of the present invention is to provide a kind of vertical air current classifyings of more grades that can obtain a variety of grade products simultaneously
Machine.
To achieve the above object, the technical solution of the more grade vertical air flow graders of the present invention is：More vertical air-flows of grade
Grader includes body and the multiple rotors erected on body, and rotor includes blade, and the rotor is divided into more than two, difference
The impeller clearance of group rotor and/or rotating speed are different, and to penetrate varigrained product, the production of same particle sizes is penetrated per group rotor
Product, and it is connected with same discharge nozzle.
Quantity per group rotor is two, and rotor is connected by diversion pipe with corresponding discharge nozzle, every group of diversion pipe
Horizontal F type channels are formed with discharge nozzle.
The corresponding discharge nozzle of each group rotor is interspersed up and down.
The rotor there are four circumference uniform distribution is set on body, the upper/lower terminal of rotor is separately fixed on body, body
On be fixed with and the corresponding rotor electric machine of rotor-position.
The lower end of the rotor is connected with maintenance body.
The beneficial effects of the invention are as follows：In gas flow sizing machine, rotor is divided into according to the difference of impeller clearance and/or rotating speed
It is more than two, same discharge nozzle is connected with per group rotor, the impeller clearance of different group rotors and/or rotating speed are different, through rotor
Product granularity it is different, a variety of grade products can be obtained simultaneously.
Description of the drawings
Fig. 1 is the structure diagram of the embodiment of the more grade vertical air flow graders of the present invention.
Specific embodiment
Embodiments of the present invention are described further below in conjunction with the accompanying drawings.
The specific embodiment of more grade vertical air flow graders of the present invention, as shown in Figure 1, the vertical air current classifying of more grades
Machine includes body 1, maintenance body 2, rotor 3, transmission mechanism 4, motor 6, diversion pipe 5 and discharge nozzle 7.It is equal that body 1 is equipped with circumference
Four rotors 3 of cloth, rotor 3 are vertical structure, and body 1 is disc structure, and the axle center of rotor 3 is located on vertical direction, with machine
The center parallel of body 1.The upper end of rotor 3 is fixed on body 1, and is communicated with diversion pipe 5, and the lower end of rotor 3 is fixed on maintenance
On body 2, rotor 3 includes blade.It is two groups that four rotors 3, which are divided to, and every group there are two rotor, the impeller clearances of opposite two rotors
Identical with rotating speed, the granularity of the product of transmission is identical, is divided into one group, and the impeller clearance and/or rotating speed between two group rotors are different
To penetrate varigrained product, it is connected per group rotor by corresponding diversion pipe 5 with discharge nozzle 7, forms horizontal F types and lead to
Road, the corresponding discharge nozzle of two group rotors are interspersed up and down.Four motors 6 are fixed on 1 upper edge of body, respectively with each turn
The position of son 3 is corresponding, and motor 6 drives 3 high speed rotation of rotor of corresponding position by transmission mechanism 4.
At work, four motors 6 drive four rotors 3 to rotate by transmission mechanism 4 respectively, and material is in the attraction of negative pressure
Under, equably the feed inlet from 1 lower section of body is fed, in the collective effect of its own gravity, blade drag and negative pressure suction force
Under, fine grained penetrates rotor 3, is discharged from the discharge nozzle 7 on body, and coarse granule can not penetrate rotor, return to underpart, due to
The impeller clearance of two group rotors and/or rotating speed are different, and the granularity of the rotor particle penetrated is different, so as to form two kinds of grade productions
Product.The rotating speed of rotor is adjusted by motor, the granularity of the particle of transmission can be adjusted.Body is overhauled by setting, convenient for air-flow
Grader is overhauled.
In other embodiments, the rotor with different leaves gap and/or rotating speed more than two can be set, so as to
It can obtain the product of two or more grades.Quantity per group rotor can be one or more.
