Detailed Description of the Embodiment

[0019] The following is a further detailed description of the present application in combination with the attached Figures 1-4 drawings.

[0020] The embodiment of the present application discloses a main bearing cooling device for a roller press. Refer to Figures 1-4, including a fixed seat 1. At the upper end of the fixed seat 1, a bearing seat 3 is fixedly connected. Inside the bearing seat 3, a main bearing 4 is provided. Outside the main bearing 4 and the bearing seat 3, a cooling box 5 is provided. The cooling box 5 is installed at the upper end of the fixed seat 1 by screws. At the upper end of the inner wall of the cooling box 5, two heat dissipation fans 8 are evenly provided. The heat dissipation fans 8 can accelerate the air flow in the cooling box 5 and improve the heat dissipation speed. In the middle of the cooling box 5, a plurality of heat conduction fins 9 are provided. At the bottom of each of the plurality of heat conduction fins 9, a U-shaped groove 10 is opened. The heat conduction fins 9 are connected to the upper end of the bearing seat 3 through the U-shaped grooves 10. Inside the plurality of heat conduction fins 9, a cooling return bend pipe 11 is penetrated. By providing the cooling box 5 outside the main bearing 4 and the bearing seat 3, and the heat dissipation fans 8, the heat conduction fins 9 and the cooling return bend pipe 11 in the cooling box 5 cooperate with each other to effectively cool the main bearing 4. The heat conduction fins 9 are tightly connected to the bearing seat 3 through the U-shaped grooves 10. Due to their good heat conduction performance, they can quickly conduct the heat generated by the main bearing 4 to themselves. The coolant in the cooling return bend pipe 11 fully contacts the heat conduction fins 9 during the flowing process, and the coolant absorbs the heat transmitted by the heat conduction fins 9, thereby further reducing the temperature of the main bearing 4 and achieving the purpose of rapid cooling, enhancing the service life of the main bearing 4. One end of the cooling return bend pipe 11 penetrates the cooling box 5 and is connected to a coolant inlet 12, and the end of the cooling return bend pipe 11 far from the coolant inlet 12 penetrates the cooling box 5 and is connected to a coolant outlet 13, so that the coolant can enter the cooling return bend pipe 11 from the coolant inlet 12, absorb the heat transferred by the heat conduction fins 9 during the flowing process in the cooling return bend pipe 11, thereby reducing the temperature of the main bearing 4, and finally flowing out from the coolant outlet 13 to complete the heat transfer and cooling process, facilitating the recovery and utilization of the coolant.

[0021] Refer to Figures 1-4, a power device 2 is installed at the upper end of the fixed seat 1. The output end of the power device 2 penetrates through the bearing seat 3 and extends to the outside of the cooling box 5. A dust-proof net 6 is fixedly connected to the upper end of the cooling box 5. The dust-proof net 6 is arranged above the two heat dissipation fans 8, which can effectively block dust from entering the interior of the cooling box 5, avoid dust accumulation on the heat dissipation fans 8 and other components, thus ensuring the normal operation of the heat dissipation fans 8, improving the heat dissipation efficiency, and extending the service life of the equipment. At the same time, the dust-proof net 6 can also prevent dust from entering the main bearing 4 area, reducing the pollution and wear of the main bearing 4, and further protecting the normal operation of the main bearing 4. The mounting brackets 7 are fixedly installed on the sides of the two heat dissipation fans 8. The heat dissipation fans 8 are detachably connected to the upper end of the cooling box 5 through the mounting brackets 7, making the installation and maintenance of the heat dissipation fans 8 more convenient. When the heat dissipation fans 8 malfunction or need to be cleaned, they can be easily detached from the cooling box 5 for repair or maintenance. Multiple heat conduction fins 9 are fixed inside the cooling box 5 through the cooling return bend pipes 11. The four corners of the multiple heat conduction fins 9 are fixed to each other and there are gaps in the middle. The mutual fixation of the four corners of the heat conduction fins 9 enhances the structural stability, and at the same time, the gaps in the middle increase the contact area with the air, which is conducive to heat dissipation.

[0022] The implementation principle of the main bearing cooling device of a roller press in an embodiment of this application is as follows: During specific use, first, the cooling box 5 is installed at the upper end of the fixed seat 1 through screws. Then, the output end of the power device 2 penetrates through the bearing seat 3 and extends to the outside of the cooling box 5 to ensure the normal operation of the equipment. When the main bearing 4 of the roller press starts to work, the heat generated by the main bearing 4 will be quickly transferred to the heat conduction fins 9. The heat conduction fins 9 are tightly connected to the bearing seat 3 through the U-shaped grooves 10 and can efficiently absorb heat. At the same time, the four corners of the multiple heat conduction fins 9 are fixed to each other and there are gaps in the middle, increasing the contact area with the air, which helps to dissipate heat. The heat dissipation fans 8 start to work, accelerating the air flow inside the cooling box 5 and taking away the heat on the heat conduction fins 9, further improving the heat dissipation efficiency. The coolant enters the cooling return bend pipe 11 from the coolant inlet 12. During the flow in the cooling return bend pipe 11, it absorbs the heat transferred from the heat conduction fins 9, thereby reducing the temperature of the main bearing 4. The coolant after absorbing heat flows out from the coolant outlet 13 and is recycled after subsequent refrigeration.
