Power transmission process: when speed regulating motor 20 rotates, driving line shaft 13 to rotate by shaft coupling 19, gas-tight silo 7 Right side and line shaft 13 are connected by sealing bearing 17, and left side is fixed on screw conveyor housing 1, therefore gas-tight silo 7 will not rotate with line shaft 13, and grinding disc 15 is coupled by second bearing 16 with line shaft 13, be fixed on sealing by fixed frame On the inner wall of 7 right side of storehouse, therefore grinding disc 15 will not be rotated with line shaft 13.Vibrating grid 12 and bogie 9 pass through retainingf key It is connected in line shaft 13, and the rotatory sealing 5 on bogie 9 and screw conveyor housing 1 couples, therefore line shaft 13 drives Vibrating grid 12 and bogie 9 rotate synchronously, and then sieve 11 is driven to rotate synchronously.The left side of line shaft 13 passes through first bearing 10 It is connected in retarder fixed frame 6, the left end of line shaft 13 and the input terminal connection of planetary reduction gear 4, the drive of shaftless screw paddle 2 Moving axis 3 couples with the output end of planetary reduction gear 4, and planetary reduction gear 4 is fixed in retarder fixed frame 6, therefore line shaft 13 revolving speed drives shaftless screw paddle 2 to rotate after 4 speed change of planetary reduction gear.The reason of selecting shaftless screw paddle 2: construction weight Gently, torque load(ing) loss is small, and especially compared to there is shaft type propeller, flexibility is larger when shaftless screw paddle works, in high speed rotation Shi Buyi forms resonance.The reason of selecting planetary reduction gear 4: small in size.
Powder transportational process: powder is inputted in screw conveyor housing 1 by feed inlet 8, the rotation of shaftless screw paddle 2 will Powder is pushed at the horn mouth on 1 right side of screw conveyor housing, and under the effect of gravity, powder slides into bell-mouthed inclined-plane and bores In shape sieve.Bell-mouthed reason is arranged: the installation site of planetary reducer 4 limits the setting of 2 right side blade of shaftless screw paddle Length, depends merely on the conveying of propeller, and powder is not easy to be transported into conical screen.
Process is sieved in the self-excited vibration of conical screen: bogie 9 and vibrating grid 12 drive sieve 11 to rotate, and powder enters taper It after sieve, is fallen at the tapered slope sieve 11 that bogie 9 is supported first, the qualified powder of the fine degree in part passes through on sieve 11 Hole leak out, fall on the inner wall of gas-tight silo 7 and along tapered slope slide downward, by the blocking of space ring 23, qualified powder It is leaked out from powder mouth 24;What the powder stayed in conical screen was supported with the rotation of sieve 11 and along tapered slope downslide vibrating grid 12 At sieve 11, since Mass Distribution of the powder on sieve is uneven and is among dynamic change, in the unbalanced of powder Under the rotary motion effect of gravity and sieve, the bracing ring 12-2 on the vibrating grid 12 of rotation is by the unbalanced centripetal of sieve 11 Power influences, this unbalanced centripetal force is passed to gusset 12-1 by bracing ring 12-2, and gusset 12-1 passes to unbalanced centripetal force Each vibration rack 12-3, vibration rack 12-3 are among the resilient clamp of compression spring 12-5 and lower pressure spring 12-6, therefore are shaken Dynamic bracket 12-3 forms vibrational state, and then drives sieve 11 to form self-excited vibration, and then drive the vibration of powder in sieve 11, Powder is in the case where vibrating the double action with rotary motion, and the qualified powder of fine degree is leaked out by the hole of sieve 11, from exciting Kinetic energy is not easy to plug sieve and improves screening efficiency, and cutter head 12-4 can cut the block material of movement, thus Improve the accepted product percentage of powder.
The attrition process of powder in conical screen: 14 and gusset 12-1 of grinding circle is fixedly connected and rotates synchronously, grinding disc 15 Relative motion is generated with for stationary state, grinding circle 14 and grinding disc 15, it is remaining to enclose 14 in grinding compared with hard block powder It is grated under the external tooth ablation of internal tooth and grinding disc 15, qualified powder passes through the through-hole and sieve hole on grinding circle 14 Leak out, remaining a small amount of hard foreign matter passes through from the helical teeth gap of grinding disc 15, and by the right side of grinding disc 15 with it is close The gap between the left side of 7 right end cap of storehouse is sealed, fall on the inner conical surface of gas-tight silo 7 and is leaked out from waste port 22.
There are gap between bogie 9 and vibrating grid 12, sieve is that steel wire more flexible works out net, therefore vibrating grid 12 Self-excited vibration is not transferred to bogie 9, ensure that the stabilization of connection ring 9-1 and rotatory sealing 5 couples, and vibrating grid 12 is from exciting It is dynamic that only sieve 11 is had an impact;The revolving speed of line shaft 13 can guarantee conical screen higher after 4 reduction of speed of planetary reduction gear Speed rotation when and 2 revolving speed of shaftless screw paddle is lower, further ensure the job stability of screening machine.
The resonance blocking cleaning work mode of sieve 11: if sieve 11 generates blockage problem, stop to screw conveyor housing 1 Interior supply powder, line shaft 13 drives conical screen idle running at this time, controls the revolving speed of speed regulating motor 20, makes the rotation frequency of screening plant Rate is close to or up to the resonant frequency of vibrating grid 12 and supported sieve 11, and sieve 11 is in more violent resonance state at this time, The powder being attached on sieve 11 falls off from sieve 11 under violent resonance state, and qualified powder is leaked out from sieve pore, does not conform to The hard foreign matter of rule can leak out from waste port 22 from popping up and gradually passing through in sieve pore, realize the block clearing program of sieve.Due to upper The elastic shock insulation effect that pressure spring 12-5, lower pressure spring 12-6 have, this resonance effects are not transferred on other components, ensure that and set Standby safe operation.
The revolving speed of drive shaft 13 can obtain preferable working effect in 600r/min or more.
Advantage:
(1) dust discharge is avoided in the course of work, pollution-free operation not will cause air pollution;
(2) production efficiency and qualification rate of powder processing greatly improved in self-excited vibration structure and grinding structure;
(3) the set equipment principle is ingenious, delicate structure, especially the setting of planetary reduction gear 4, and it is steady that work greatly improved Qualitative, volume and weight is small, produces convenient for motor-driven setting.
