Summary of the invention
Instant invention overcomes the shortcoming that preparation equipment of the prior art effectively can not be separated ultrafine powder particle, provide a kind of device be separated for powder granule.
The technical scheme that the present invention realizes goal of the invention employing is: a kind of device be separated for powder granule, described device comprises receiver, revolving top, the power assembly of feed hopper and band speed changer, described receiver is provided with one group of radially spaced toroidal membrane, receiver is divided into the storage bin of one group of annular by toroidal membrane, revolving top comprises: rotating disk and cover plate, center of turntable is provided with circular feed cavity, uniform on rotating disk cylindrical one group of powder granule spiral discharging mouth be communicated with circular feed cavity is set, cover plate and rotating disk end face form contact structures through sealing gasket, feed hopper is connected with cover plate, the circular feed cavity of discharging opening on cover plate and rotating disk of feed hopper forms connectivity structure, the output shaft of the power assembly with speed changer is fixedly connected with the rotating disk axis hole of revolving top, the power assembly other end with speed changer is fixedly connected with receiver, the powder granule that storage bin on receiver and revolving top form different quality is along the powder granule isolating construction fallen into respectively after the powder granule spiral discharging mouth of rotating disk is dished out in corresponding storage bin.
The invention has the beneficial effects as follows: the present invention is based on kinetic energy theory, the powder granule of different quality obtains different kinetic energy at revolving top, after dishing out along the powder granule spiral discharging mouth of revolving top with identical initial velocity, due to the displacement of quality influence movement, the powder granule of different quality falls in the storage bin of diverse location respectively.Adopt this device effectively can carry out separated and collected to powder granule, there is the advantages such as structure is simple, good separating effect.
Below in conjunction with accompanying drawing and detailed description of the invention, the invention will be further described.
Accompanying drawing explanation
Fig. 1 is structural representation one of the present invention.
Fig. 2 is the A-A sectional view of Fig. 1.
Fig. 3 is structural representation two of the present invention.
In accompanying drawing, 1 be receiver, 1-1 is toroidal membrane, 1-2 is that storage bin, 2 is revolving top, 2-1 is rotating disk, 2-1-1 is powder granule spiral discharging mouth, 2-2 is cover plate, the power assembly, 5 of 2-3 be circular feed cavity, 3 to be feed hopper, 4 be band speed changer is powder granule conveyer.
Detailed description of the invention
As shown in accompanying drawing 1,2, a kind of device be separated for powder granule of the present embodiment, described device comprises the power assembly 4 of receiver 1, revolving top 2, feed hopper 3 and band speed changer.Described receiver 1 is provided with one group of radially spaced toroidal membrane 1-1, and for coordinating different powder granule to be separated, the present embodiment preferred toroidal membrane 1-1 is the adjustable structure of diameter.Receiver 1 is divided into the storage bin 1-2 of one group of annular by toroidal membrane 1-1.Conveniently collect the powder granule of storage bin 1-2, be provided with powder granule conveyer 5 bottom the preferred storage bin 1-2 of the present embodiment, the bottom of storage bin 1-2 is annular cone structure.Revolving top 2 comprises: rotating disk 2-1 and cover plate 2-2.Rotating disk 2-1 center is provided with circular feed cavity 2-3, uniformly on rotating disk 2-1 cylindrical arranges one group of powder granule spiral discharging mouth 2-1-1 be communicated with circular feed cavity 2-3.Cover plate 2-2 and rotating disk 2-1 end face form contact structures through sealing gasket.Feed hopper 3 is connected with cover plate 2-2, and the circular feed cavity 2-3 of discharging opening on cover plate 2-2 and rotating disk 2-1 of feed hopper 3 forms connectivity structure.The output shaft of the power assembly 4 with speed changer is fixedly connected with the rotating disk 2-1 axis hole of revolving top 2, and the power assembly 4 of band speed changer drives rotating disk 2-1 to rotate.Power assembly 4 other end with speed changer is fixedly connected with receiver 1.The powder granule that storage bin 1-2 on receiver 1 and revolving top 2 form different quality is along the powder granule isolating construction fallen into respectively after the powder granule spiral discharging mouth 2-1-1 of rotating disk 2-1 dishes out in corresponding storage bin 1-2.Revolving top 2 is apart from the height of receiver 1, and the width of each storage bin 1-2 needs the powder granule characteristic according to process, as the concrete condition such as treating capacity, granularmetric composition is determined.In order to optimize operating environment, prevent powder granule from entering in the air, as shown in Figure 3, receiver 1 is provided with upper cover.
The present invention is according to theorem of kinetic energy:
wherein m is the quality of powder granule, and v is the movement velocity of powder granule.In the rotating disk 2-1 rotary course of revolving top 2, the powder granule motion in revolving top 2 obtains kinetic energy E
kfly out along powder granule spiral discharging mouth 2-1-1, and with speed v in the spatial movement having certain medium, the resistance being simultaneously subject to medium makes its speed slow down, and is finally zero.The kinetic energy E of powder granule in this process
kbe converted into powder granule work W.
Pass through
draw,
wherein S is the displacement of particle moving, and F is resistance.If the initial velocity v that powder granule obtains is identical, the resistance F be subject to is identical, and the displacement S of the larger powder granule of quality m movement is in media as well larger.Medium in a device can be air, also can be the protective gas such as nitrogen, air curtain, weak electric field, low-intensity magnetic field etc. can also be set.
During actual use, the powder granule be separated is needed to enter in revolving top 2 from feed hopper 3.Power assembly 4 with speed changer drives rotating disk 2-1 to rotate, and powder granule obtains kinetic energy and flies out along powder granule spiral discharging mouth 2-1-1, and the powder granule of final different quality falls in different storage bin 1-2.Adopt this device, the mineral close for density or even ultrafine powder particle can effectively be separated.
