[0021] In the technical scheme, a cooling structure of a granulator includes a granulating device 100, which includes a material storage pipe 110, a cooling shell 120, a motor 130 and a rotating disk 140. A feed frame 111 is welded to the top of the material storage pipe 110, two cooling shells 120 are welded to the bottom of the material storage pipe 110, a conduit 122 is plugged into the outer wall of the cooling shell 120, a jet head 123 is plugged into the inner wall of the cooling shell 120, and the bottom of the inner cavity of the cooling shell 120 is filled with coolant. A motor 130 is fixed to the front side wall of each cooling shell 120 by bolts, and the rotating disk 140 is rotatably connected to the inner wall of the cooling shell 120 through a rotating seat, and is key-connected to the motor 130. A molding cavity 141 is opened on the outer wall of the rotating disk 140, and the molding cavities 141 on the outer walls of the two rotating disks 140 correspond to each other.

[0022] In this technical solution, the material storage tube 110 and the feed frame 111 are used to store molten materials, the cooling shell 120 is used to install the motor 130 and the rotating disk 140, the motor 130 is used to drive the rotating disk 140 to rotate, and while the two rotating disks 140 are rotating, their molding cavities 141 are constantly overlapped, so that the molten material can be cooled, formed and dropped, and the conduit 122 and the nozzle 123 are used in conjunction with each other to blow away the liquid in the molding cavity 141.

[0023] In some technical solutions, reference Figure 1 A connecting plate 113 is welded to both sides of the material storage pipe 110 , and the other end of the connecting plate 113 is welded to the outer wall of the cooling shell 120 .

[0024] In this technical solution, the use of the connecting plate 113 can improve the connection strength between the cooling shell 120 and the material storage pipe 110, and prevent positional deviation during granulation.

[0025] In some technical solutions, reference Figure 1 A reinforcing plate 112 is welded to the bottom of the material storage pipe 110 , and the reinforcing plate 112 is fixed to the outer wall of the cooling shell 120 by bolts.

[0026] In this technical solution, the use of the reinforcing plate 112 can seal the gap between the material storage tube 110 and the cooling shell 120 to prevent the leakage of the molten material.

[0027] In some technical solutions, reference Figure 1-2 A guide plate 121 is welded to the lower portion of the openings of the two cooling shells 120 .

[0028] In this technical solution, the use of the guide plate 121 can guide the formed granules to prevent the granules from falling out of the storage frame during the falling process.

[0029] In some technical solutions, reference Figure 2-3 A rotating ring 142 is welded on one side of the rotating disk 140 , and the rotating ring 142 is embedded in the inner wall of the cooling shell 120 and rotates therewith.

[0030] In this technical solution, the use of the rotating ring 142 can enable the rotating disk 140 to rotate stably with the inner wall of the cooling shell 120 , preventing displacement and contact and friction with the inner wall of the cooling shell 120 .

[0031] In some technical solutions, reference Figure 2 A telescopic rod 124 is fixed to the inner wall of the cooling shell 120 by bolts, a guide head 126 is welded to the end of the telescopic rod 124, a spring 125 is sleeved on the outside of the telescopic rod 124, and a wiping cloth is embedded at the end of the guide head 126.

[0032] In this technical solution, the telescopic rod 124, the spring 125 and the guide head 126 cooperate with each other to enable the guide head 126 to reciprocate so that the wiping cloth contacts the inner wall of the molding cavity 141 and then wipes off the residual liquid on the inner wall of the molding cavity 141.

[0033] In some technical solutions, reference Figure 2 An arc plate 127 is welded to the end of the guide head 126 .

[0034] In this technical solution, the use of the arc plate 127 can reduce the resistance encountered by the guide head 126 when leaving the inner cavity of the molding cavity 141 , so that the guide head 126 can easily leave the inner cavity of the molding cavity 141 .

[0035] Working principle: The molten material is introduced into the inner cavity of the storage tube 110 through the feed frame 111, and the control switches of the two motors 130 are turned on. The motor 130 on the left drives the rotating disk 140 to rotate clockwise, and the motor 130 on the right drives the rotating disk 140 to rotate counterclockwise, so that the joint of the two rotating disks 140 can complete the overlap of the molding cavity 141, and the molding cavity 141 can intercept the material during the rotation process, and then when the overlap occurs, they can be fused and cooled together to form a whole and can be automatically The pellets 141 are then dropped, and the corresponding forming cavity 141 after granulation is transferred to the coolant in the inner cavity of the cooling shell 120 for cooling. After rotating out of the liquid surface, the nozzle 123 and the conduit 122 generate airflow to blow the inner wall of the forming cavity 141 to remove the droplets. After rotating to the guide head 126, the guide head 126 slides along the inner wall of the forming cavity 141 under the action of the telescopic rod 124 and the spring 125, and then wipes the inner wall of the forming cavity 141. Granulation is carried out repeatedly according to the above steps.
