[0018] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with an embodiment. The embodiment is only used to explain the present invention and does not constitute a limitation on the protection scope of the present invention.

[0019] according to Figure 1 , 2 As shown in Figures 3 and 4, this embodiment proposes a constant temperature heating device for liquefying grinding grease, including a support frame 1 and a heating tank 2. A heating tank 2 is provided on one side of the top of the support frame 1, a heating mechanism is provided on the outer side of the heating tank 2, an assembly frame 4 is provided on the other side of the top of the support frame 1, a heat dissipation mechanism is provided on the top of the assembly frame 4, a liquid outlet pipe 5 is connected at the outlet of the heat dissipation mechanism, a transportation mechanism is provided at the bottom of the heating tank 2 and the heat dissipation mechanism, the grinding grease is put into the interior of the heating tank 2, and the heating mechanism is set to 200 degrees Celsius to automatically heat it at a constant temperature to change it into liquid, and then it is transported to the interior of the heat dissipation mechanism through the transportation mechanism, the heat dissipation mechanism cools down the liquid grinding grease to prevent the residual temperature of the grinding grease from continuing to heat it and causing it to fail, and then the liquid grinding grease is discharged from the heat dissipation mechanism through the liquid outlet pipe 5 to the outside.

[0020] The heating mechanism includes an operating table 3 and an electric heating tube 6. The operating table 3 is provided on one side of the heating tank 2. The electric heating tube 6 is provided on the outside of the heating tank 2. The shape of the electric heating tube 6 is provided with a coil structure, and a layer of insulation shell is provided on the outside. The operating table 3 is composed of an HMI touch screen, a PLC, a three-phase thyristor trigger, a three-phase thyristor assembly, a PT100 temperature sensor, and a heater. Through the three temperature sensors embedded in the oil barrel, in cooperation with the PLC and the three-phase thyristor trigger, constant temperature heating can be set in the range of 0℃-200℃ to ensure that the grease in the oil barrel will not have the risk of local overheating. When the oil temperature in the oil barrel reaches the set temperature, the heater enters the constant temperature control stage, and the temperature sensor collects the temperature in the oil barrel in real time, inputs the PLC to establish RS485 communication with the trigger, and controls the trigger to adjust the size of the thyristor conduction angle, thereby controlling the size of the current of the main circuit heating element to ensure that the heating process is constant temperature and controllable.

[0021] A fixing frame 10 is provided on the outside of the heating tank 2, and a motor 11 is installed on the top of the fixing frame 10. The output end of the motor 11 is connected to a stirring mechanism matching the heating tank 2, and the stirring mechanism includes a rotating shaft 12, a scraper 13 and a spiral blade 14. The output end of the motor 11 is connected to the rotating shaft 12, and a scraper 13 is fixed to the top of the rotating shaft 12. The bottom end of the rotating shaft 12 is connected to the spiral blade 14. Since the rotating shaft 12 is connected to the output end of the motor 11, the motor 11 can drive the rotating shaft 12 to rotate inside the heating tank 2, so that the rotating shaft 12 drives the scraper 13 and the spiral blade 14 to stir the grinding fat inside the heating tank 2, and then the grinding fat is evenly heated inside the heating tank 2, which is beneficial to the heating of the grinding fat.

[0022] A filter disc 7 is provided at the bottom of the rotating shaft 12, and the outer side of the filter disc 7 is snap-connected with the top of the heating tank 2. The filter disc 7 is set as a split structure and is snap-connected by an elastic buckle 8. A plurality of filter holes 9 are distributed in an annular manner on the bottom of the filter disc 7. When the grinding grease enters the interior of the heating tank 2, it will first fall into the interior of the filter disc 7, and the scraper 13 cooperates with the filter holes 9 at the bottom of the filter disc 7 to scrape the grinding grease through the interior of the filter disc 7, breaking up the grinding grease entering the heating tank 2, reducing the viscosity of the grinding grease and making it easier to be heated and liquefied. The filter disc 7 is a split structure and is spliced ​​together by the elastic buckle 8, so that the filter disc 7 can be easily taken out from the top of the heating tank 2 for cleaning.

The copper tube 15 and the bottom of the heating tank 2 are connected to each other by the connecting pipe 19, and a valve is provided on the connecting pipe 19 at the bottom of the heating tank 2. The oil pump 18 cooperates with the connecting pipe 19 to automatically transport the liquefied grinding grease after heating the inside of the heating tank 2 to the inside of the copper tube 15.

[0024] The heat dissipation mechanism includes a copper tube 15, heat dissipation fins 16 and a fan 17. The copper tube 15 is fixed on the top of the assembly frame 4. The copper tube 15 is composed of a plurality of U-shaped tubes connected in series. A plurality of heat dissipation fins 16 are equidistantly arranged on the outside of the copper tube 15. Fans 17 are symmetrically arranged on both sides of the assembly frame 4, and the rotation directions of the blades of the two fans 17 are different. The two fans 17 rotate to allow air to pass through the copper tube 15 and be discharged after heat exchange with the copper tube 15. The heat dissipation fins 16 on the outside of the copper tube 15 can increase the contact area between the air and the copper tube 15, so that the heat exchange effect between the copper tube 15 and the air is better, which is convenient for cooling the grinding grease.

[0025] The grinding grease liquefaction constant temperature heating device puts the grinding grease into the interior of the heating tank 2, and automatically heats it at a constant temperature to change it into a liquid state through the electric heating tube 6 set to 200 degrees Celsius, and then transports it to the interior of the heat dissipation mechanism through the oil pump 18 and the connecting pipe 19. The two fans 17 rotate to allow air to pass through the copper tube 15 and be discharged after heat exchange with it. The heat dissipation fins 16 on the outside of the copper tube 15 can increase the contact area between the air and the copper tube 15, so that the heat exchange effect between the copper tube 15 and the air is better, the grinding grease is cooled, and the residual heat of the grinding grease is prevented from continuing to heat it and causing it to fail.
