Simply introduce the operation principle of this ejecting device with pooling feature 100 below.
When first motor 120 started, the slip that is used for granulation was sent in the shower nozzle by feed pipe simultaneously, and described ejecting device 100 begins to enter duty.The startup of described first motor 120, drive its rotating shaft 122 high speed rotating, the driving gear 130a that this rotating shaft 122 and then drive link together with it, driving gear 130a is by acting on driven gear with driven gear 130b engagement, driven gear acts on outer shaft 140, and then drives shower nozzle 150 rotations of lower end.If slip all flows directly into shower nozzle from feed pipe 160, then can cause greater impact, and then influence the stability of shower nozzle 150 rotating speeds shower nozzle 150.The instability of shower nozzle 150 rotating speeds causes slip too much accumulation in shower nozzle 150 easily, occurs clogging easily, or the thickness of the centrifugal liquid layer in the shower nozzle 150 is too small, influences the granulation quality.In an embodiment of the present invention because of in shower nozzle 150, having set up baffle plate 152, make and have only the fraction slip to flow directly in the shower nozzle 150 in the fill process, and most slip is all earlier through just falling into shower nozzle 150 bottoms after baffle plate 152 cushioning effects.Slip constantly throws away from a plurality of spray orifices 151 by shower nozzle 150 stable rotation centrifugal force, forms high-quality particle, has also improved yield rate in the quality that guarantees granulation.
Fig. 2 has showed that ejecting device of the present invention has second embodiment of the ejecting device of pooling feature, and the ejecting device 200 of second embodiment is to improve on the basis of first embodiment ejecting device 100.With reference to Fig. 2 and in conjunction with Fig. 6, axle 270 and some paddles 255 in ejecting device 200 described in this embodiment also comprises, baffle plate 252 is fixed on the described paddle 255.Axle 270 is sheathed between described outer shaft 140 and the described feed pipe 160 successively by the clutch shaft bearing assembly 271 and second bearing assembly 272 in described, so that stably rotate at its place, position.Described paddle 255 is located in the described shower nozzle 150 and is connected in the lower end of described interior axle 270.Particularly, described paddle 255 is fixedly connected on the fixture 256 of a hollow, and this fixture 256 is fixed on the lower end of described interior axle 270 by screw.Preferably, described paddle 255 can be provided with four, but is not limited to four, can carry out suitable increase and decrease according to the concrete shape size of paddle 255 and the concrete structure of shower nozzle 150.
Simultaneously, baffle plate 252 is not to be fixed on the shower nozzle 150 among this embodiment, but is fixed on the described paddle 255 with the layout identical with first embodiment.Since described baffle plate 252 be mounted on the described paddle 255, the size of baffle plate 252 is less with respect to baffle plate 152, can make its terminal central shaft near shower nozzle 150.
In the present embodiment, when described ejecting device 200 enters duty, described shower nozzle 150 rotates, described paddle 255 maintains static, then paddle 255 can rotate with respect to described shower nozzle 150, described paddle 255 and baffle plate 252 all can stir the slip in the shower nozzle 150, make that the multiple different material in the slip evenly mixes.
Fig. 3 has the schematic diagram of the 3rd embodiment of the ejecting device of pooling feature for the present invention, the ejecting device 300 of the 3rd embodiment and the difference of second embodiment ejecting device 200 are that mainly ejecting device 300 also comprises second transmission mechanism 330 among this embodiment, and described baffle plate 252 is spirally distributed in the described shower nozzle 150.Described second transmission mechanism, 330 1 ends are connected with first motor 120, and the other end is connected with interior axle 270, make the motor 120 of winning can drive described interior axle 270 and rotate.
Particularly, described second transmission mechanism 330 is a gear assembly, places the top of first transmission mechanism 130.Described second transmission mechanism 330 comprises a driving gear 330a and a driven gear 330b, this driven gear 330b is solidly set on the upper end of described interior axle 270, and described driving gear 330a still links to each other with the rotating shaft 122 of described first motor 120, simultaneously, described driving gear 330a and described driven gear 330b two engagements.
Owing to increased by second transmission mechanism 330, axle 270 and outer shaft 140 rotated simultaneously in first motor 120 can drive when starting, and then drive paddle 255 and the shower nozzle 150 be provided with baffle plate 252 and rotate together, described baffle plate 252 is distributed on the described paddle 255 spirally simultaneously, reach better buffering and mixing effect, and then effectively improve the granulation quality with yield rate.
Fig. 4 has showed that the present invention has the 4th embodiment of the ejecting device of pooling feature, the difference of the ejecting device 400 of the 4th embodiment and the 3rd embodiment ejecting device 300 is that mainly described ejecting device 400 also comprises second motor 420, second transmission mechanism 330 is to be connected with this second motor 420, the both sides of axle 270 in described second motor 420 and first motor 120 are installed on symmetrically.Described second transmission mechanism, 330 1 ends are connected with described second motor 420, and the other end is connected with described interior axle 270.
Present embodiment is controlled the rotation of described interior axle 270 separately by setting up second motor 420, further controls the rotation of described paddle 255 and described baffle plate 252, and its control accuracy is higher.Turn to and the rotating speed of shower nozzle 150 and paddle 255 is respectively by first motor 120 and the 420 independent controls of second motor, so turning to rotating speed of shower nozzle 150 and paddle 255 can be set at different parameter values according to the needs of concrete granulation process, so that adapt to the requirement of different granulation conditions.
Know that easily the baffle plate that the present invention has the ejecting device of pooling feature is not limited in above-mentioned shape or layout, any design of playing effective buffering and suitable drainage all may be utilized, and belongs to protection scope of the present invention.Simultaneously, the parts that are used for fixing connection among the present invention also are not limited only to screw, and any suitable fixedly connected mode all can be used for connecting each parts of ejecting device of the present invention.The concrete structure of the miscellaneous part of ejecting device involved in the present invention is well known to those of ordinary skill in the art, no longer is described in detail at this.
Above invention has been described in conjunction with most preferred embodiment, but the present invention is not limited to the embodiment of above announcement, and should contain various modification, equivalent combinations of carrying out according to essence of the present invention.
