At last, in conjunction with the accompanying drawings, the principle of work of the prilling granulator of the high production capacity of the utility model high quality is explained in detail.
In conjunction with Fig. 1, the principle of work of first embodiment of the prilling granulator of the high production capacity of the utility model high quality is described.When first motor 11 is opened, first shaft coupling 119 that drive is installed on first motor output shaft 111 rotates, first shaft coupling 119 rotates and orders about first drive shaft, 314 rotations of fixedlying connected with first shaft coupling 119, under first drive shaft 314 rotates, drive first driving toothed gear 310 and second driving toothed gear 320 that are installed on same first drive shaft 314 and rotate simultaneously; Then, when first driving toothed gear 310 and 320 rotations of second driving toothed gear, order about first follower gear 311 and 321 rotations of second follower gear respectively; Then, under the rotation of first follower gear 311, order about the outer shaft 42 that is fixed on first follower gear 311 and rotate, and then drive shower nozzle 5 rotations that are fixed on the outer shaft 42, finally realize the function of the manufacturing fertiliser granulates of shower nozzle 5.Meanwhile, under the rotation of second follower gear 321, ordering about the interior axle 41 that is fixed on second follower gear 321 rotates, and then make the paddle 7 that is fixed on the interior axle 41 rotate, thereby realize the stirring of paddle 7 and pulverize slip, and cushion the direct impact of slip, thereby make the evenly big or small of shower nozzle 5 produced fertiliser granulates and one-tenth particle rate height to shower nozzle 5.Like this, under the unlatching of first motor 11, realize being synchronized with the movement of first transmission rig 31 and second transmission rig 32, thereby realized the synchronous working of paddle 7 and shower nozzle 5, and then realized the granulation function of the prilling granulator of the high production capacity of high quality.
Again in conjunction with Fig. 2, the principle of work of prilling granulator second embodiment of the high production capacity of the utility model high quality is described in detail.When second motor 10 is opened, can drive the rotation of second driving toothed gear 320 that is connected with second motor 10, second driving toothed gear 320 orders about second follower gear 321 that is meshed with second driving toothed gear 320 and rotates when rotating, thereby driving the interior axle 41 that is fixed on second follower gear 321 rotates, when interior axle 41 rotates, can order about 7 rotations of the paddle on the axle 41 in being fixed on, thereby make paddle 7 to stir the slip that feed-pipe 6 transports and to pulverize, and cushion the direct impact of slip to shower nozzle 5, thereby assurance shower nozzle 5 can be worked reposefully.Meanwhile, when first motor 11 is opened, can drive the rotation of first driving toothed gear 310 that is connected with first motor 11, thereby first driving toothed gear 310 rotates the rotation that drives first follower gear 311 that is meshed with first driving toothed gear 310,311 rotations of first follower gear can be ordered about the outer shaft 42 that is fixed on first follower gear 311 and rotate, then when outer shaft 42 rotates, thereby driving the shower nozzle 5 that is fixed on the outer shaft 42 rotates around the axial line of shower nozzle 5, thereby make shower nozzle 5 to carry out processing treatment, make the fertiliser granulates function thereby finish shower nozzle 5 to the slip that transports from paddle 7.Wherein, the work of paddle 7 and shower nozzle 5 is to coordinate mutually, coordinate mutually by paddle 7 and shower nozzle 5, thereby the realization prilling granulator is made the function of fertiliser granulates.Simultaneously, when real work, according to actual needs, first and second motor 11,10 can be controlled paddle 7 and shower nozzle 5 rotates in the same direction or the rotation of phase negative side; Can also satisfy the needs of paddle 7 and 5 pairs of different rotating speeds of shower nozzle, and then make the even and one-tenth particle rate height of the produced fertiliser granulates of prilling granulator of the high production capacity of high quality of the present utility model.
The prilling granulator of the high production capacity of the utility model high quality is owing to have axle center place and offer the outer shaft 42 and the outer shaft 42 of accommodating feed-pipe 6 and be positioned on the same medullary ray with shower nozzle 5, paddle 7 and baffle plate 70, the prilling granulator of the high production capacity of high quality of the present utility model can be cushioned transport slip shower nozzle 5 is impacted from feeding tube 6, prevent that shower nozzle from producing whipping when work, and then make shower nozzle 5 in that rotate can be more steady, work more reliably, thereby make that the produced fertiliser granulates of prilling granulator of the high production capacity of high quality is more even and become the particle rate higher, in addition, because slurry can directly flow in the shower nozzle by feed-pipe 6 from the slurry mixing device, improved input speed greatly, thereby make production capacity be greatly enhanced, facts have proved that the prilling granulator of the high production capacity of the utility model high quality improves 50%-300% than traditional prilling granulator that passes through the side charging at least in production capacity; Therefore, the utility model can also make production capacity be greatly enhanced under the situation that improves the granulation quality.
The discharge port of the slip mixing device that the prilling granulator of the high production capacity of the utility model high quality is related and the shape of support 2, bearing 411,412,421 and 3140 and the selection of shaft coupling 119 and first and second motor 11,10 principle of work be well known to those of ordinary skill in the art, no longer be described in detail at this.
Above disclosed only is preferred embodiment of the present utility model, can not limit the interest field of the utility model certainly with this, and therefore the equivalent variations of being done according to the utility model claim still belongs to the scope that the utility model is contained.
