[0027] To better understand the purpose, structure, and function of the present utility model, the following further describes in detail a plastic particle cooling device of the present utility model with reference to the accompanying drawings.

[0028] As Figures 1-5As shown in the figure, a plastic particle cooling device of the present utility model includes a cooling barrel 1. Three support legs 2 distributed in a circumferential array are provided at the bottom of the cooling barrel 1. A top plate 3 is provided at the top of the cooling barrel 1. A rotating cylinder 4 rotatably connected to the cooling barrel 1 is provided in the inner cavity of the cooling barrel 1. The top of the rotating cylinder 4 extends above the top plate 3 and is rotatably connected to the top plate 3. The cooling barrel 1 is a hollow structure, and the rotating cylinder 4 is a hollow structure with an open bottom. The outer diameter of the rotating cylinder 4 is smaller than the inner diameter of the cooling barrel 1. A plurality of uniformly and orderly distributed through holes are provided on the surface of the rotating cylinder 4 below the top plate 3. A feed port 5 is provided on one side of the top of the rotating cylinder 4. A liquid inlet pipe 6 is provided on one side of the top of the top plate 3. A discharge port 15 is provided at the middle part of the bottom of the cooling barrel 1. A sealing plug is provided on the discharge port 15. A drain pipe 10 is provided on one side of the bottom of the cooling barrel 1 where the discharge port 15 is located. A control valve is provided on the drain pipe 10. A filter screen is provided at the inlet end of the drain pipe 10. Through the feed port 5, plastic particles can be put into the rotating cylinder 4. By opening the sealing plug, the plastic particles in the rotating cylinder 4 can be discharged. Through the liquid inlet pipe 6, coolant can be input into the cooling barrel 1. Through the drain pipe 10, the coolant in the cooling barrel 1 can be discharged. Under the action of the filter screen, the phenomenon that plastic particles are discharged with the coolant can be effectively prevented.

[0029] A driving mechanism for driving the rotation of the rotating cylinder 4 is provided on the cooling barrel 1. The driving mechanism includes a second motor 8. The second motor 8 is fixedly connected to the side wall of the cooling barrel 1 through a fixing plate. The second motor 8 is connected to the rotating cylinder 4 through a belt drive assembly 9. A small pulley is connected to the shaft of the second motor 8. A large pulley is sleeved on the top of the rotating cylinder 4. The large pulley and the small pulley are connected by a belt. When the second motor 8 is started, under the action of the belt drive assembly 9, the rotating cylinder 4 rotates rapidly. Thus, under the action of centrifugal force, the liquid adhering to the plastic particles due to water cooling is quickly thrown out, which is beneficial to the rapid air drying of the plastic particles after cooling, greatly improving the working efficiency. An annular edge 19 is provided at the bottom edge of the rotating cylinder 4. An annular groove corresponding to the annular edge 19 is provided on the inner wall of the bottom of the cooling barrel 1. The size of the annular edge 19 matches the size of the annular groove, and the annular edge 19 is slidably connected to the annular groove. Through the cooperation between the annular edge 19 and the annular groove, an auxiliary limiting effect is exerted on the rotating cylinder 4, making the rotating cylinder 4 more stable.

[0030] The inner cavity of the rotating cylinder 4 is provided with a stirring shaft 17. The top end of the stirring shaft 17 extends above the rotating cylinder 4 and is connected with a first motor 7. The first motor 7 is fixedly connected with the upper surface of the rotating cylinder 4 through a U-shaped frame. A plurality of uniformly and orderly distributed stirring rods 18 are arranged on the side wall of the stirring shaft 17, and the stirring shaft 17 is rotationally connected with the rotating cylinder 4 through a bearing. A blowing component for blowing air on the rotating cylinder 4 is arranged on the side wall of the cooling barrel 1. The blowing component includes a blower 11 and three air outlet pipes 14 distributed in a circumferential array. The three air outlet pipes 14 are distributed on the outer surface of the cooling barrel 1, and a plurality of equally spaced air outlet heads 16 are arranged on each air outlet pipe 14. The three air outlet pipes 14 are connected through a branch pipe 13, and the blower 11 is connected with one of the branch pipes 13 through a main pipe 12. The air outlet heads 16 extend into the inner cavity of the cooling barrel 1, and a sealing component is arranged at the connection between the air outlet heads 16 and the cooling barrel 1. The blower 11 can be placed on the ground or fixed on the cooling barrel 1 through a fixing frame. During the high-speed rotation of the rotating cylinder 4, the blower 11 can be started, so that the air outlet heads 16 on the three air outlet pipes 14 blow air on the rotating cylinder 4. Cooperating with the high-speed rotation of the rotating cylinder 4 is beneficial to the rapid air drying of plastic particles, enabling the plastic particles to be directly air dried after being cooled, thus greatly improving the work efficiency.

[0031] The working principle of this plastic particle cooling device: When in use, plastic particles are put into the rotating cylinder 4, and a coolant is input into the cooling barrel 1 through the liquid inlet pipe 6. At this time, the plastic particles in the rotating cylinder 4 will be immersed in the coolant for cooling. At the same time, the first motor 7 is started, so that the stirring shaft 17 drives the stirring rods 18 to rotate, thereby enabling the stirring rods 18 to stir the plastic particles, so that the plastic particles can fully and evenly contact with the coolant, accelerating the cooling efficiency of the plastic particles and improving the cooling effect at the same time. After cooling, the control valve of the drain pipe 10 is opened to discharge the coolant in the cooling barrel 1. Then, the second motor 8 and the blower 11 are started, so that the rotating cylinder 4 rotates at a high speed, and the coolant on the rotating cylinder 4 and the plastic particles is thrown out at a high speed. Cooperating with the blowing of the air outlet heads 16, the drying efficiency of the plastic particles is accelerated, and thus the work efficiency is greatly improved. After that, the plastic particles are discharged by opening the sealing plug.
