In this embodiment, after the raw materials pass through the screening assembly 101, the raw materials are uniformly distributed on the fluidized bed, at this time, the control panel 10 starts the peristaltic pump 205, the compressed air and the adhesive solution are mixed according to a preset proportion, the mixed solution after atomization is processed by atomization technology, the mixed solution after atomization is conveyed into the two upper granulation spray heads 201 and the two lower granulation spray heads 214 through the conveying pipe 206 and the two guide pipes, then, the mixed solution is uniformly sprayed on the powder in the fluidized state on the fluidized bed in an atomized mode, meanwhile, the auxiliary motor 202 is started, one of the first rotating shafts 208 is driven to rotate, the other first rotating shaft 208 is synchronously rotated under the action of the driving rotating rod and the fifth synchronous belt 216, the two second rotating shafts 209 are driven to rotate under the driving of the fourth synchronous belt 203, the rotating shafts 208 and the second rotating shafts 209 are driven to rotate together, the rotating of the rotating blocks 207 drive the telescopic rods 215 which are in sliding connection with the rotating shafts, the rotating shafts 215 cause the movable sleeves 212 and the swing rods 213 which are movably arranged in the movable sleeves 212 to swing up and down, the swing plates 213 at two ends of the swing rods 213 are connected with the upper granulation spray the lower granulation spray the raw materials uniformly on the surfaces of the upper granulation spray the raw materials;
Through setting up a set of last granulation shower nozzle 201 and a set of lower granulation shower nozzle 214 on the different height of granulator, can be at the accurate adhesive that sprays of different float levels of raw materials, guaranteed that the different parts and the level of raw materials can both obtain even wetting to improved the homogeneity and the quality of pelletization, it should be noted that two first pivots 208 drive through the fifth hold-in range 216 that establishes on auxiliary motor 202 and the initiative dwang respectively, and auxiliary motor 202's output is roughly the same with initiative motor 105, and two first pivots 208 rotation rate have certain deviation and do not influence spraying efficiency.
As shown in fig. 1-9, the control panel 10 is in control connection with the drive motor 105, the auxiliary motor 202, the peristaltic pump 205, the screening assembly 101, and the comminuting motor 120.
In this embodiment, as the raw materials are continuously subjected to the action of hot air and the binder in the granulator, the surfaces of the raw materials are gradually wetted and bonded together to form particles, the particles roll and collide in the granulator and are continuously fused, so that the particle size is gradually increased, when the granulation process is nearly finished, the control panel 10 adjusts the size of the sieving holes of the sieving component 101 to be increased to the size of qualified particle size, at the moment, the induced draft fan still blows, the particles are gradually increased and become more compact in the granulation process, the weight and density of the particles are increased, the gravity action of the particles is correspondingly increased along with the increase of the particles, the particles tend to fall rather than continuously float after the particles meet the weight and size required by granulation, then fall into the bin 7 through the aperture regulated by the sieving component 101, and the particles with larger particle size in the granulation process are trapped on the sieving component 101, so that the accurate control of the particle size of the finished product is realized, after the granulation process is finished, the cleaning bin door 8 is opened, and an operator can directly clean the inside the sealing bin 11 to prepare for the next granulation.
The foregoing description of the preferred embodiments of the invention is not intended to be limiting, but rather is intended to cover all modifications, equivalents, alternatives, and improvements that fall within the spirit and scope of the invention.
