Spiral case beater 200 is reached, and is finally reached cyclone cylinder and dust arrester installation.Above-mentioned powder concentrator 100 includes that shell 110 and setting exist
Two groups of deflectors 122 in shell 110, deflector 122 and the angle of wind direction can be adjusted.
Specifically, Fig. 1 and Fig. 2 are please referred to, the generally V-type of shell 110, shell 110 includes feed inlet 112, feed opening
114, the top of shell 110 is arranged in air inlet 116 and gas outlet 118, feed inlet 112；Feed opening 114 is arranged in shell 110
Lower part.110 overall structure of shell and the too big difference of nothing in the prior art, therefore it is not described in detail.
With continued reference to FIG. 1, powder concentrator 100 includes two guiding subassemblies 120, each guiding subassembly 120 includes multiple flat
The deflector 122 of row interval setting.Multiple 122 parallel intervals of deflector are arranged within the case 110, and vertical with side plate.
Shaft 124 is connected on the leeward of deflector 122, shaft 124 is arranged perpendicular to side plate, the both ends of shaft 124
There is bearing, deflector 122 is rotatably connected by shaft 124 with side plate respectively.The setting of shaft 124 can reduce on leeward
Impact of the material to shaft 124, improves its service life.In addition, the edge of deflector 122 and side plate keep lesser gap,
In order to the rotation of deflector 122.Multiple shafts 124 are linearly arranged along reference direction (A-B in attached drawing 1).
In order to adjust the angle of deflector 122 Yu wind direction, powder concentrator 100 is also provided with driving device 130.The driving dress
130 settings are set outside the shell 110, including motor 132, interlocking bar 134 and multiple rocking bars 136.Multiple rocking bars 136 are set in parallel
It sets and is connect respectively with the end vertical of the shaft 124, and the end of rocking bar 136 is hinged with the interlocking bar 134 respectively；

Other shafts 124 are moved to rotate.
Since the wind speed in shell 110 is bigger, the wind-force that deflector 122 is subject to is bigger, in order to enable deflector 122
It is fixed on predeterminated position；Powder concentrator 100 in the present embodiment is also provided with locking device 140.Locking device 140 be mainly used for by
Rocking bar 136 and grabbing test on the occasion of a baby's first birthday locking, prevent it from rotating under the action of the forces of the wind.
Locking device 140 includes locking level 142 and lockplate 144；Lockplate 144 is rectangular slab, the appearance with side plate
Face is vertically fixedly connected；Strip-shaped hole is provided on lockplate 144.One end of locking level 142 and one of rocking bar 136 are hinged；
The other end includes thread segment, and thread segment passes through strip-shaped hole.There are two nuts 146, nut 146 to be located at lock for setting on thread segment
The two sides of fixed board 144.Since locking level 142 is locked by nut 146 and lockplate 144, locking level 142 cannot be moved, this
So that the rocking bar 136 being attached thereto is not able to rotate, so that by it, her rocking bar 136 is locked by interlocking bar 134.When needing to adjust
When the angle of deflector 122, nut 146 is unscrewed, locking level 142 is moved, to release the lock to rocking bar 136
It is fixed.
122 rotational angle of deflector is excessive in order to prevent, leads to equipment damage, and powder concentrator 100 is also provided with limiting device.
The limiting device includes first stroke switch 152 and second stroke switch 154, the first stroke switch 152 and described
Two travel switches 154 are connect with the outer wall of the shell 110, are provided respectively therein the two sides of a rocking bar 136；And point
It is not electrically connected with the motor 132.When rocking bar 136 encounters travel switch, motor 132 can be automatically powered off.
Since powder concentrator 100 includes two guiding subassemblies 120, it has been correspondingly arranged two locking devices 140 and limit
Device, and it is mutually indepedent.
Please continue to refer to Fig. 1 and Fig. 5, the spiral case beater 200 includes spiral case 210 and dispersing device 220；The spiral case
210 global shapes and blower are substantially similar, including curved slab and two spaced surface plates, and the surface plate passes through described
Curved slab connection；It is provided with air inlet on the curved slab, air outlet is provided on one of surface plate, lower part, which is provided with, to be fallen
Material mouth 212.The air inlet of the spiral case 210 is connect with the air outlet of the V-type powder concentrator 100；Air outlet and cyclone cylinder are (in figure
It is not shown) connection.
The dispersing device 220 includes 221, two annular slabs 223 of drive shaft and multiple breaks up blade 224.The drive shaft
221 is horizontally disposed, and connect with the bearing block of one end 227, forms cantilever beam.The annular slab 223 is circular slab, described in two
The setting of 223 parallel interval of annular slab, and be fixedly connected by connecting rod 226 with the drive shaft 221.In the drive of external motor
Under, drive shaft 221 can drive annular slab 223 to rotate.
The blade 224 of breaing up is bar shaped plate, and the both ends for breaing up blade 224 respectively can with the annular slab 223
Dismantling connection, also, the blade 224 of breaing up is perpendicular to the tangential direction of the annular slab 223, and along the annular slab 223
It is uniformly distributed.
In the present embodiment, for the ease of replacing to the blade 224 of breaing up of damage, the inside of annular slab 223 is convenient for setting
Set slot 2232, break up the both ends of blade 224 respectively with 2232 grafting of slot on two annular slabs 223.Above-mentioned design is also
Can prevent centrifugal force causes to break up blade 224 and falls off.
Please continue to refer to Fig. 6 and Fig. 7, blade 224 is broken up in order to further fix, prevents its play, in annular slab 223
Outside is additionally provided with multiple limit plates 225, and each limit plate 225 is used to limit the 2-3 plays for breaing up blade 224.Work as needs
When blade 224 is broken up in replacement, it is only necessary to will be close to corresponding limit plate 225 on the annular slab 223 of 210 air outlet of spiral case and remove i.e.
It can.
In order to improve the service life for breaing up blade 224, breaing up blade 224 includes steel plate and the volume that steel plate outer layer is arranged in
Wearing layer processed.
The working principle of above-mentioned spiral case beater 200 is as follows；
In use, drive shaft 221 drives annular slab 223 to rotate, when in wind and material movement to spiral case 210, leaf is broken up
Piece 224 hits material；Its one side can be by the crushing material of bulky grain, and on the other hand can will cannot crush big
Grain is hit down so that it is fallen by the blanking port 212 of 210 bottom of spiral case.
It should be noted that above-mentioned select powder system that can also use V-type powder concentrator in the prior art.
Above description is merely a prefered embodiment of the utility model, is not intended to limit the utility model, for
For those skilled in the art, various modifications and changes may be made to the present invention.All spirit and original in the utility model
Within then, any modification, equivalent replacement, improvement and so on be should be included within the scope of protection of this utility model.
