Description
Technical field
The present invention relates to a kind of lytag raw material prilling granulator, be specifically related to a kind of lytag raw material substep prilling granulator.
Background technology
Lytag raw material prilling process generally is that the interior compound of granulation blending bunker is delivered on the pelletizing disks by conveying device at present; compound is at disk running back nucleation and the last granulating of rotation, and namely compound is made the process of examining to granulation at the disk of rotation and all finished in disk.But this make examine to the process of granulation all in disk Method Of Accomplishment have serious deficiency, enter namely that discrete particles in the compound on the rotating circular disk is done random rolling and ball and not of uniform size the causing of grain of producing, shape is also irregular, particle is in conjunction with closely not causing green ball strength poor, and is frangible after the moulding; Compound is made to examine to the process of granulation at the disk of rotation and all finish the time that needs than long in disk simultaneously, makes granulation efficiency low.
Summary of the invention
The objective of the invention is in order to overcome deficiency of the prior art, provide a kind of simple in structure, easy for installation and can greatly improve the lytag raw material substeps prilling granulator of granulation efficiency.
For achieving the above object, the invention provides a kind of lytag raw material substep prilling granulator, comprise granulation blending bunker, air pump, conveying pipeline, extruding jet and pelletizing disks, described granulation blending bunker lower end is provided with the pneumatic push-pull valve of control blowing amount, described pelletizing disks lower end is provided with transmission device, transmission device comprises hoist cylinder and hydraulic pressure pole, be provided with interior involute helicoid in the described conveying pipeline, the interior involute helicoid helical pitch in the conveying pipeline is 1/2nd of conveying pipeline diameter; Described extruding jet is provided with several tapered squeezing holes, and the diameter of the lateral port in tapered squeezing hole is less than inboard mouthful diameter.
Described extruding jet is positioned at pelletizing disks center top and is 1/4th of pelletizing disks radius to the distance at pelletizing disks center.
The outer vortex of involute helicoid is 1/2nd of conveying pipeline diameter to the distance of conveying pipeline axis in described, and the inner vortex of interior involute helicoid is 1/4th of conveying pipeline diameter to the distance of conveying pipeline axis.
Beneficial effect of the present invention: lytag raw material substep prilling granulator of the present invention is simple in structure, easy for installation; Lytag raw material substep prilling granulator carries out simultaneously making the conveying of nuclear operation and compound, makes whole granulation efficiency improve 1/3rd times than the production efficiency of conventional apparatus; The ball intensity height that the pressure eddy airstream is produced can prolong the granulation rolling time and makes that the grain intensity produce is higher, the breakage rate of minimizing green-ball in circular flow thereby adjust the pelletizing disks inclination angle simultaneously.
Below in conjunction with accompanying drawing lytag raw material substep prilling granulator of the present invention is described further.

Specific embodiment
As shown in Figure 1; the lytag raw material substep prilling granulator of present embodiment comprises granulation blending bunker 1, air pump 3, conveying pipeline 9, extruding jet 5 and pelletizing disks 6; granulation blending bunker 1 lower end is provided with the pneumatic push-pull valve 2 of control blowing amount; pelletizing disks 6 lower ends are provided with transmission device 10, and transmission device 10 comprises hoist cylinder 7 and hydraulic pressure pole 8.Involute helicoid 4 in being provided with in the conveying pipeline 9, the diameter of conveying pipeline 9 is 20 centimetres, the interior involute helicoid 4 helical pitch length in the conveying pipeline 9 are that 1/2nd of conveying pipeline 9 diameters are 10 centimetres.Extruding jet 5 is positioned at pelletizing disks 6 centers tops and is 1/4th of pelletizing disks 6 radiuses to the distance at pelletizing disks 6 centers.
As shown in Figure 2, extruding jet 5 is provided with several tapered squeezing holes 12, and the diameter of the lateral port 13 in tapered squeezing hole 12 is less than inboard mouthful 11 diameters.
As shown in Figure 3, Figure 4, the outer vortex 14 of interior involute helicoid 4 is that 1/2nd of conveying pipeline 9 diameters are 10 centimetres to the distance of conveying pipeline 9 axis, and the inner vortex 15 of interior involute helicoid 4 is that 1/4th of conveying pipeline 9 diameters are 5 centimetres to the distance of conveying pipeline 9 axis.
When using the present invention to work; earlier pneumatic push-pull valve 2 is opened and made compound flow into conveying pipeline 9 charging apertures by granulation blending bunker 1; the forced draft that is produced by air pump 3 is sent into compound the conveying pipeline 9 that is provided with interior involute helicoid 4 again; do the spiral running along internal thread 4 under the eddy airstream effect that compound is formed by involute helicoid in conveying pipeline 9; the molecule that the while eddy airstream orders about in the compound also is to turn round regularly; and the mutual bump and bonding and form a plurality of small spheroids of the molecule in the compound; small spheroid is by the tapered squeezing hole 12 on the eddy airstream propelling extruding jet 5; big or small unanimity and the very high microsphere of closeness extruded by tapered squeezing hole 12 are ball, so carrier pipe 9 existing defeated material are made kernel function again.The inclination angle that pelletizing disks 6 is adjusted pelletizing disks 6 by hoist cylinder 7 and the hydraulic pressure pole 8 of transmission device 10, ball enter roll in the pelletizing disks 6 of rotation and the bonding compound that is scattered after then the ball behind the bonding compound is ascending and become the grain that meets production requirement, the grain intensity height that the ball rolling time was grown and caused when the inclination angle of pelletizing disks 6 was big, the qualified grain of producing when the inclination angle diminishes flows out from pelletizing disks 6.
