As can be known from the above technical solutions, the present invention is sucked ambient atmos in assorting cylinder using negative pressure device, which can
The material of material and heavier mass to lighter weight in assorting cylinder carries out classification processing, reaches the quality uniformity for improving finished product
Purpose；And by the size for adjusting negative pressure device suction force, the finished product of specified particle size is collected, is greatlyd improve
The powder of milling system is collected and classification adaptability.
Detailed description of the invention
Fig. 1 is a kind of structural schematic diagram of preferred embodiment of the present invention.
Fig. 2 is the schematic cross-sectional view of Fig. 1.
Specific embodiment
The present invention is discussed in detail below with reference to Fig. 1, Fig. 2:
The assorting cylinder of dry type milling system, including hollow cylinder 3, the cylinder top is equipped with to be entered for the material after ball milling
The feed pipe 31 of the cylinder lumen, the present invention is not limited to the material after ball milling, all raw material powder can also be with cylinder lower part
Enter the air inlet pipe 32 of the cylinder lumen equipped with supplied gas, the negative pressure device that the cylinder top is arranged in makes ambient atmos from institute
Air inlet pipe 32 is stated into cylinder lumen, into cylinder lumen gas by the material of the inner cavity lighter weight blow from bottom to top to
It is flowed out after cylinder top, the material of heavier mass is flowed out from the discharge port 34 that cylinder bottom end is arranged in from top to bottom, to realize
The classification of material improves the uniformity of final product quality.Wherein, exhaust fan etc. can be used in negative pressure device, and can be by adjusting negative pressure
The size of device suction force changes the gas flow rate in sucking assorting cylinder, since gas with various flow velocity can blow difference from bottom to top
The particle of quality, therefore this mode can reach the finished product that particle size is specified from cylinder collected overhead.Air inlet pipe of the invention
Upper also settable air cleaner guarantees that the air in sucking assorting cylinder is more clean, while can control humidity, avoids
Influence the quality of material.Meanwhile vibrating head can be also provided on cylinder, it prevents material sticks on cylinder, keeps material complete
It is flowed out from discharge port.
Specifically, the cylinder 3 includes two conical shells setting up and down, and upper and lower conical shell is upper end diameter
Greatly, lower end diameter is small, and upper conical 35 lower end inner cavity of cylinder and 36 upper end inner cavity of inferior pyramidal cylinder form stepped hole 37, the stepped hole
Upper end diameter is small, and lower end diameter is big.Since air inlet pipe setting is in cylinder lower part, ambient atmos are inhaled by negative pressure device from air inlet pipe
After entering, can enter in minor diameter from large diameter hole from bottom to top by stepped hole, so that gas similar to spurting into
Enter upper conical cylinder lumen, to improve the flow velocity of gas；Simultaneously as the feed pipe of material after ball milling from upper conical cylinder
After, the approximate centerline of cylinder can be converged in flow process from top to bottom, and small diameter bore just can be right at this time
The material of quasi- convergence avoids the occurrence of object so that impacting the material of convergence in the gas tremendous range of small diameter bore
Material classification blind area.
In the present invention, the upper conical cylinder is flexibly connected with inferior pyramidal cylinder；Movable connection method is such as: the epicone
Shape cylinder bottom end peripheral wall is outward extended with extension board 38, step surface of the extension board as stepped hole, inferior pyramidal cylinder top
End peripheral wall is installed with lug 39, and the extension board is flexibly connected with lug by bolt 310, and bolt such as wing bolt etc. is convenient for
Disassembly and installation, and the mode being flexibly connected is convenient for the separation of upper and lower conical shell, maintains easily and clean cylinder.The present invention is simultaneously
It is not limited to the mode of bolt flexible connection, buckle etc. also can be used and be flexibly connected.
In implementation process, conical shell top and the bottom end up and down are extended with a truncated cylinder body 311, the design of cylinder
Be conducive to be attached with other component, the cylinder design on following conical shell top is conducive to that lug and air inlet pipe etc. is arranged；
And the air inlet pipe is arranged on the cylinder along the tangential direction of inferior pyramidal cylinder top cylinder, may make gas along cylinder in this way
Spiral inner wall rises, and the material of convergence, after material is dispersed by impact, heavier mass are impacted after small diameter bore promotes flow velocity
Material overcomes the impact force of gas to flow out from bottom end discharge port, and the material of lighter weight then edge under the action of gas impact force
The spiral inner wall of upper conical cylinder rises, and finally flows out at the top of cylinder；Since the upper end diameter of upper conical cylinder is big, lower end is straight
Diameter is small, therefore the material of lighter weight can further disperse during spiral, and there may be a part of quality at this time
Relatively heavy material overcomes gas impact force to flow out from bottom end discharge port again, the quality phase of the material flowed out in this way from top
To relatively light, to achieve the purpose that further to separate light matter material.
For another example, the cylinder design of inferior pyramidal cylinder bottom end is conducive to discharge, and upper conical cylinder bottom end cylinder design not only has
Benefit discharging also helps connection extension board, and the design of upper conical cylinder top cylinder be conducive to sealing cover and feed pipe etc. into
Row connection；And the feed pipe is arranged on the cylinder along the tangential direction of upper conical cylinder top cylinder, since material is in gas
Along cylinder inboard wall spiral under the action of body impact force, therefore the feed pipe of tangent line setting and the air inlet pipe of tangent line setting make
Material comes into full contact with gas, guarantees that gas farthest impacts material, can further avoid stock grading blind area occur；?
In implementation process, the tangential direction of the two is preferably reversed, and impact effect is more preferable.
Above embodiment is used for illustrative purposes only, and is not limitation of the present invention, related technical field
Those of ordinary skill without departing from the spirit and scope of the present invention can be with various changes can be made and modification, therefore institute
There is equivalent technical solution also to should belong to scope of the invention.
