It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0020] In the following description, many specific details are set forth to facilitate a full understanding of the present invention.

A second heating pipe 7 is fixedly connected to the inner surface of the oil tank 6. Both side end surfaces of the second heating pipe 7 penetrate the oil tank 6 and extend to the outside. A connecting pipe 8 is fixedly connected to the outer surface of the oil tank 6 away from the water tank 1. A circulating pump 9 is fixedly connected to the end surface of the connecting pipe 8. A circulating pipe 10 is fixedly connected to the output end of the circulating pump 9. The first heating pipe 5 is connected to the second heating pipe 7. A water inlet pipe 2 is fixedly connected to the outer surface of the water tank 1. An overflow pipe 3 is fixedly connected to the outer surface of the water tank 1. The water inlet pipe 2 and the overflow pipe 3 are both connected to the water tank 1. The overflow pipe 3 is located on the upper side of the water inlet pipe 2. The circulating pipe 10 is connected to the first heating pipe 5.

[0022] The effect achieved by the entire embodiment 1 is that when the granulator is processing, the condensed water drainage pipe of the granulator is connected to the water inlet pipe 2, and the condensed water generated by the operation of the granulator can be sent into the water storage tank 1 through the water inlet pipe 2. At this time, the water storage tank 1 can store hot water of about 70 degrees. Then, through the setting of the first heating pipe 5, the hot water stored in the water storage tank 1 can heat the water in the first heating pipe 5. The circulating pump 9 is started and can extract the heated water in the first heating pipe 5 through the connection of the second heating pipe 7. After the heated water is pumped into the second heating pipe 7, the grease in the oil tank 6 can be heated. For heating, the setting of using the condensed water generated by the operation of the granulator for heating can save energy consumption. At the same time, the method of slowly heating with hot water is not easy to cause the problem of too high oil temperature. Then, the water in the second heating tube 7 after completing heat exchange with the oil in the oil tank 6 will return to the first heating tube 5 through the circulation tube 10. The hot water continuously injected into the water storage tank 1 can continuously heat the first heating tube 5. Through the setting of the overflow pipe 3, while the condensed water is sent into the water inlet pipe 2, the hot water will flow out from the overflow pipe 3, so as to realize the real-time replacement of the hot water in the water storage tank 1, thereby maintaining the temperature in the water storage tank 1.

[0025] Working principle: When the pellet mill is processing, the condensed water drain pipe of the pellet mill is connected to the water inlet pipe 2, and the condensed water generated by the operation of the pellet mill can be sent into the water storage tank 1 through the water inlet pipe 2. At this time, the water storage tank 1 can store hot water of about 70 degrees. Then, through the setting of the first heating pipe 5, the hot water stored in the water storage tank 1 can heat the water in the first heating pipe 5. The circulating pump 9 is started and can extract the heated water in the first heating pipe 5 through the connection of the second heating pipe 7. After the heated water is pumped into the second heating pipe 7, the oil in the oil tank 6 can be heated. Then, the second heating pipe 7 and the oil in the oil tank 6 are heated. The water after heat exchange will return to the first heating tube 5 through the circulation pipe 10. The hot water continuously injected into the water tank 1 can continuously heat the first heating tube 5. Through the setting of the overflow pipe 3, while the condensed water is sent into the water inlet pipe 2, the hot water will flow out from the overflow pipe 3, so as to realize the real-time replacement of the hot water in the water tank 1, so as to maintain the temperature in the water tank 1. Through the setting of the temperature probe 11, the temperature of the hot water stored in the water tank 1 can be monitored in real time. Through the setting of the display screen 4, the staff can conveniently view the temperature data in real time, which is convenient for timely debugging of the equipment and improves the practicability of the device.
