[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present application with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments in the present application without creative efforts belong to the scope of protection of the present application.

[0020] Please refer to Figure 1-2 , the present utility model provides a technical solution: including a recycling box 1, a hot water pipe 2 is connected to the top of the recycling box 1, and an impeller 11 is arranged on the upper side inside the recycling box 1. The impeller 11 is located below the hot water pipe 2, and a rotating shaft 12 passes through and is in interference fit with the middle of the impeller 11. Bevel gears 16 are fixedly installed at both ends of the rotating shaft 12. Air inlet holes 4 and exhaust holes 5 are respectively opened on both sides of the top of the recycling box 1, and a driving shaft 13 and a driving shaft 14 are respectively arranged on both sides inside the recycling box 1. Bevel gears 17 are fixedly connected to the outer walls of the driving shaft 13 and the driving shaft 14. The bevel gear 16 is meshed with the bevel gear 17. An air inlet fan 6 is fixedly installed at the upper end of the driving shaft 13, and the air inlet fan 6 is located inside the air inlet hole 4. An exhaust fan 7 is fixedly installed at the upper end of the driving shaft 14, and the exhaust fan 7 is located inside the exhaust hole 5. Stirring blades 15 are fixedly installed at the lower ends of the driving shaft 13 and the driving shaft 14;

[0021] In this technical solution, the cooling hot water of the plastic granulator injected into the recycling box 1 through the hot water pipe 2 will impact the impeller 11, driving the impeller 11 and the rotating shaft 12 to rotate. The rotating shaft 12 drives the driving shaft 13 and the driving shaft 14 to rotate through the bevel gear 16 and the bevel gear 17, thereby driving the air inlet fan 6, the exhaust fan 7 and the stirring blades 15 to rotate, converting the potential energy of the cooling hot water into the kinetic energy of the rotation of the air inlet fan 6, the exhaust fan 7 and the stirring blades 15, and accelerating the air flow and the cooling hot water flow for heat dissipation without using electric energy, saving energy.

[0022] In some technical solutions, as Figure 1-3 shown, a plurality of heat exchange copper tubes 20 are arranged inside the recycling box 1. The front end of the heat exchange copper tube 20 is connected to a liquid inlet pipe 8, and the rear end of the heat exchange copper tube 20 is connected to a liquid discharge pipe 21. The liquid inlet pipe 8 and the liquid discharge pipe 21 respectively penetrate the front side and the rear side of the recycling box 1. The heat exchange copper tube 20 is in a spiral shape.

[0023] During use, by injecting cold water into the liquid inlet pipe 8, since the spiral-shaped heat exchange copper tube 20 can increase the heat exchange time between the cold water and the cooling hot water, the cooling effect on the cooling hot water is further increased.

[0024] In some technical solutions, as Figure 1 shown, a filter box 9 is fixedly installed on the top of the recycling box 1, and the hot water pipe 2 is connected to the liquid discharge end of the filter box 9.

[0025] During use, the cooling hot water can be filtered through the filter box 9 to remove impurities in the cooling hot water of the plastic particle granulator, so as not to affect recycling.

[0026] In some technical solutions, such as Figure 2 As shown, two first support members 18 are sleeved on the rotating shaft 12. The first support members 18 are connected to the rotating shaft 12 through bearings, and the top of the first support members 18 is fixedly installed on the inner wall of the top of the recycling box 1. Two second support members 19 are sleeved on the first driving shaft 13 and the second driving shaft 14 respectively. The second support members 19 are connected to the first driving shaft 13 and the second driving shaft 14 through bearings respectively, and one end of the second support members 19 is fixedly installed on the inner wall of the recycling box 1.

[0027] During use, the stability of the rotation of the rotating shaft 12, the first driving shaft 13 and the second driving shaft 14 is ensured by the first support members 18 and the second support members 19.

[0028] In some technical solutions, such as Figure 1-2 As shown, a cold water pipe 3 is communicated with the lower part of one side of the recycling box 1, and a gate valve is arranged on the cold water pipe 3.

[0029] During use, by opening the gate valve on the cold water pipe 3, the cooled cooling hot water of the plastic particle granulator can be discharged.

[0030] In some technical solutions, such as Figure 1 As shown, moving wheels 10 are fixedly installed at the four corners of the bottom of the recycling box 1.

[0031] During use, the moving of the recycling device is facilitated by the moving wheels 10.

[0032] Working principle: During the use process, the cooling hot water can be filtered through the filter box 9 to remove impurities in the cooling hot water of the plastic particle granulator. The cooling hot water impacts the impeller 11 through the hot water pipe 2, driving the impeller 11 and the rotating shaft 12 to rotate. The rotating shaft 12 drives the first driving shaft 13 and the second driving shaft 14 to rotate through the first bevel gear 16 and the second bevel gear 17, and then drives the intake fan 6, the exhaust fan 7 and the stirring blade 15 to rotate, converting the potential energy of the cooling hot water into the kinetic energy of the rotation of the intake fan 6, the exhaust fan 7 and the stirring blade 15. Without using electric energy, the air flow and the cooling hot water flow can be accelerated for heat dissipation, saving energy. And by injecting cold water into the liquid inlet pipe 8, since the heat exchange copper pipe 20 in a spiral shape can increase the heat exchange time between the cold water and the cooling hot water, the cooling effect on the cooling hot water is further increased.
