Dynamic connection, the motor C206 are sequentially connected by the transmission ring 4 on speed reducer 5 and the lower screen drum 203, the upper screen drum
202 revolving speed be greater than the lower screen drum 203 revolving speed (presence of speed difference makes particle from upper screen drum 202 to lower screen drum 203
When be easier to sift out from the sieve pore of lower screen drum 203)；The screen cylinder 302 is externally provided with transmission ring 4, and the motor D305 passes through
Transmission ring 4 outside speed reducer 5 and the screen cylinder 302 is sequentially connected；It is apparent that the mode of motor driven rotation is not limited to
This.
The mechanical working principle of the described screening of the present embodiment is: the particle to sub-sieve successively passes through pneumatic separation device 1, tiltedly
To screening plant 2 and tail portion screening plant 3, the particle to sub-sieve can use elevator and rise in feed hopper 103, to sub-sieve
Particle falls through into feeder 104 from feed hopper 103, and the particle fallen is exported from the flat strip of feeder 104 in the form of sheets,
Suitable size can be being adjusted according to the actual situation by the wind-force of blower 105(blower 105) when, biggish particle is because by the wind retrodeviating
Turn smaller, eventually enter into the discharge bucket A110 in the left side of lower clapboard 109 and be discharged, lesser particle because wind-engaging post deflection is excessive, from
Be discharged outside sieve 107 and be collected in wind sleeve 108, and non-woven fabrics or ordinary polyester cloth can be used from wind sleeve 108(wind sleeve in wind) in row
Out, other powder collections are in discharge bucket B111, and are expelled to from the selection by winnowing discharge nozzle 112 of the bottom discharge bucket B111 oblique
In the upper screen drum 202 of screening plant 2, upper 202 revolving speed of screen drum is very fast, internal bristle be it is movable, can be changed in stress
Position, bristle play the role of a blocking, and the furthermore collective effect of centrifugal force and gravity to particle, and some can pass through
The particle of upper 202 sieve pore of screen drum can fall, and particle in addition enters lower screen drum 203, and lower 203 revolving speed of screen drum is relative to upper screen drum
202 is relatively slow, but its bristle be it is fixed, bristle is stronger to the active force of particle, and furthermore centrifugal force and gravity is common
Effect, some can be fallen by the particle of lower screen drum 203, guiding of these particles to fall in oblique reclaiming plate 212
It is discharged under effect from oblique discharge port 213；And other particles are discharged into the charging cover of tail portion screening plant 3 from lower screen drum 203
301, and screen cylinder 302 is eventually fallen into, screen cylinder 302 gyrates, and internal particle is finally from the sieve pore of screen cylinder 302
The particle for sifting out, and being eventually positioned in screen cylinder 302 in 309 cannot be discharged because partial size is larger, can finally open the discharge of door 310
It collects.Upper screen drum 202, lower screen drum 203 and the sieve pore of screen cylinder 302 can as it is big, and the hole at sieve can be relatively smaller.
The described screening of the present embodiment is mechanical, its beneficial effect is: can be by bulky grain and small using pneumatic separation device 1
Particle separates first, then is further sorted by oblique screening plant 2 and tail portion screening plant 3, and selection by winnowing has been gathered
Advantage, while oblique screening plant 2 and tail portion screening plant 3 are shaken using the screening mode of rotary type relative to present vibrating screen
Dynamic screening mode noise obviously can reduce, practical.
It should be understood that elevator can also not had to, but itself is a the conical bottoms of batch can be sieved for feed hopper 103
Portion, and wait sieve material because technological reason is directly stored in wait sieve in batch can.
Embodiment 2:
As shown in figure 5, the described screening of the present embodiment is mechanical, unlike the first embodiment: 101 top of casing
Equipped with opening 113,104 two sides of feeder are arranged with guide rod seat 114, and 104 both ends of feeder are equipped with can be in guide rod seat 114
Mobile guide rod 115,114 side of guide rod seat is fixed with motor A116, motor A116 and a screw rod 117 wherein
Transmission connection, the screw rod 117 pass through respective guide rod seat 114 after with 118 bolt of the nut being connected on feeder 104,
The guide rod seat 114 is equipped with bearing for the screw rod 117 place of passing through.
The described screening of the present embodiment is mechanical, in motor A116(preferably with stepper motor) under the action of, feeder
104 can move left and right, and the different granular sizes that decision is discharged from discharge bucket A110 of 104 position of feeder, feeder 104 is got over
It close to blower, has more particles and is fallen from discharge bucket A110, feeder 104 is further away from blower, and only biggish particle is
Discharge can be fallen from discharge bucket A110, be can according to need and artificially adjusted.
Embodiment 3:
As shown in Figure 6,7, the described screening of the present embodiment is mechanical, and unlike the first embodiment: the blower 105 divides
For upper fan A119 and lower blower B120, upper spacer 121 is equipped in the casing 101, the upper spacer 121 is located at upper fan
Between A119 and lower blower B120,121 left side lower section of upper spacer is equipped with separate hopper A122, lower right-hand side is equipped with separate hopper B123,
The separate hopper A122 and the outlet of the strip of the bottom separate hopper B123 are all located at the 121 left side lower section of upper spacer, and separate hopper
The outlet of A122 is closer to lower blower B120；The left side refers to closer to the direction of blower 105；
The improvement of the present embodiment is equally applicable to the scheme of embodiment 2.
The described screening of the present embodiment is mechanical, and bulky grain, which is equivalent to, has carried out selection by winnowing twice, and bulky grain is upper for the first time
Partition 121 is exported from the strip of separate hopper A122 and is discharged every to the left side, and because it is closer to lower blower B120, they are finally also only
It can be discharged from discharge bucket A110；And certain this bulky grain for the first time because of a variety of causes (such as mutually collide, initial position) by every
Plate 121 is every to the right, they are after the strip of separate hopper B123 outlet discharge at second, under the action of lower blower B120 not
It is enough excessive deflection, is finally also discharged from discharge bucket A110, such mode can as far as possible arranges bulky grain at pneumatic separation device 1
Out, after reduction road oblique screening plant 2 and tail portion screening plant 3 pressure.
Embodiment 4:
The present embodiment is related to a kind of sizing screening method of plastic grain, it plastic grain is divided into A, B from big to small,
C, D level Four, it is characterized in that using the machinery of screening described in 1-3 of the embodiment of the present invention, using elevator by the plastics to sub-sieve
Particle is sent into feed hopper 103, and discharge is A grades from discharge bucket A, and collecting out of screen cylinder 302 is B grades, from oblique discharge port
It is C grades with collecting tank collection, collecting from wind sleeve is D grades.This sizing screening method spy small with convenient, noise
Point can replace traditional vibrating screen.
Above-described embodiment is merely illustrative, it will be apparent that, the protection scope of this patent is not limited to the above embodiments.To upper
The protection scope of this patent should be fallen by stating various equivalent modifications made by embodiment.
