[0002] Pelletizing is a method of artificial block raw materials. It is a process of converting powdered materials into physical properties and chemical composition that can meet the requirements of the next step of processing.

[0003] In the prior art, when the temperature of the pellets is high and water cooling is directly performed, it is easy to cause water to react with the surface of the pellets, thereby causing the pellets to explode, thereby increasing the frequency of safety accidents. In response to the above problem, the application number is: 202310845284.3, which discloses a pellet cooling device, which includes a shell, support columns are fixedly installed at the four corners of the bottom surface of the shell, a rotating disk is provided on the top surface of the shell, a protective cover is provided on the outer circular wall surface of the rotating disk, and a discharge pipe is fixedly installed on one side of the shell; a cooling component, which is arranged inside the shell and used to cool the pellets;

[0004] However, after reading the above patent documents, the following problems are found: when in use, it is necessary to drive through the cooperation of the motor, the first electric push rod and the second electric push rod. Although this process has a good cooling effect, it requires a set of huge cooling equipment, has the disadvantages of high operating costs, large mechanical energy consumption, complex structure and increased maintenance costs, which needs to be improved.

The half gear 6 is driven by the motor 5 to rotate and intermittently transmit with the gear 7, so that the gear 7 drives the round rod 8 to rotate intermittently, and the round rod 8 drives the circular plate 2 to rotate intermittently. At the same time, the circular plate 2 makes the pellet 14 move intermittently through the action of the plurality of grooves 12, thereby achieving the purpose of automatically conveying the pellet 14.

[0027] In this embodiment, the cooling mechanism includes an air cooler 3 and an air pipe 4. The air cooler 3 is fixedly installed at the bottom of the shell 1. The air outlet end of the air cooler 3 is sealed and connected to two air pipes 4. One end of the two air pipes 4 passes through the shell 1 and is flush with the inner wall of the shell 1. Through the action of the cooling mechanism, the first cooling of the pellet 14 can be achieved. In this process, since the two air pipes 4 deviate from the center of the pellet 14 by a certain distance, the air flow discharged from the two air pipes 4 causes the pellet 14 to rotate in the corresponding groove 12, thereby improving the cooling effect of the pellet 14.

[0028] In this embodiment, the conveying mechanism includes a fixed frame 9 and a guide pipe 10. A groove 2 is opened on the shell 1, and the guide pipe 10 is embedded in the groove 2. The guide pipe 10 is fixedly sleeved with a fixed frame 9, and the fixed frame 9 is fixedly connected to the shell 1. The pellets 14 to be cooled are placed in the guide pipe 10, and at the same time, the pellets 14 move downward by gravity and fall into the corresponding groove 12. Due to the blocking effect of the pellets 14 at the bottom on the remaining pellets 14, the pellets 14 slide into the corresponding groove 12 one by one, thereby achieving the effect of automatically placing the pellets 14 in the groove 12.

[0029] In this embodiment, pellets 14 are provided in the guide tube 10 and the multiple grooves 12, and the multiple grooves 12 are adapted to the multiple pellets 14. The multiple pellets 14 are respectively contacted and connected with the guide tube 10, the circular plate 2 and the shell 1, so as to facilitate the limiting of the pellets 14 and the movement of the pellets 14.

[0030] In this embodiment, a discharge port 11 is opened on the shell 1, and the discharge port 11 corresponds to one of the multiple grooves 12. A guide plate 13 is fixedly installed on the shell 1, and the guide plate 13 corresponds to the discharge port 11, which is used to discharge the pellets 14 after cooling and facilitate the next step of work.

[0033] Working principle: when in use, first put the pellet 14 to be cooled into the guide tube 10, and at the same time, the pellet 14 moves downward by gravity and falls into the corresponding groove 12. Since the pellet 14 at the bottom blocks the rest of the pellets 14, the pellets 14 slide into the corresponding grooves 12 one by one, thereby achieving the effect of automatically placing the pellets 14 into the grooves 12; the half gear 6 is driven by the motor 5 to rotate and intermittently transmit with the gear 7, so that the gear 7 drives the round rod 8 to rotate intermittently, and the round rod 8 drives the circular plate 2 to rotate intermittently, and the circular plate 2 makes the pellet 14 move intermittently through the action of multiple grooves 12, thereby achieving the purpose of automatically conveying the pellet 14; when the pellet to be cooled moves to the position corresponding to the two air pipes 4, the cold air is passed through the cold air The function of the machine 3 is to discharge the cooling airflow from the two air pipes 4 and act on the corresponding pellets 14, thereby realizing the first cooling of the pellets 14. In this process, since the two air pipes 4 deviate from the center of the pellets 14 by a certain distance, the airflow discharged from the two air pipes 4 causes the pellets 14 to rotate in the corresponding grooves 12, thereby improving the cooling effect of the pellets 14; then, through the intermittent driving of the driving mechanism, the pellets 14 are moved to the position of the water cooling device 15, so that the water cooling device 15 cools the pellets 14 for the second time; thereafter, through the intermittent driving of the driving mechanism, the cooled pellets 14 are moved to the position of the discharge port 11, and the pellets 14 are automatically discharged from the discharge port 11 through the action of the slope on the shell 1.

[0034] The technical progress achieved by the utility model compared with the prior art is that through the coordination of various components, not only the cooling effect of the pellets is improved, but also the mechanical energy consumption and maintenance costs are reduced, and the pellets 14 can be cooled in an orderly manner, avoiding the inefficiency of the cooling components caused by direct accumulation, thereby improving the cooling efficiency and being more practical.
