Cement mills are characterized by strong adaptability to materials, continuous production capability, large crushing ratio, and easy speed adjustment to achieve the desired fineness of the ground product.

[0003] The currently published patent, CN213669626U, discloses a novel cement mill with a simple structure and convenient operation. By setting a first spring and a second spring, the vibration of the drive motor during operation can be reduced, resulting in good vibration reduction. By setting a motor cover, the impact of dust on the normal operation of the drive motor can be reduced. The sound insulation cotton can absorb the noise emitted by the motor during operation, reducing the harm of noise to the operator. This utility model has a simple structure, can achieve vibration reduction and noise reduction, and is highly practical, making it worthy of use and promotion.

[0004] Based on the above search results, when the cement mill is in use, the sound insulation cotton can absorb the noise emitted by the motor during operation, reducing the harm of noise to the operator. It can achieve vibration reduction and noise reduction, and is highly practical. However, the sound insulation cotton covering the surface of the motor will affect the heat dissipation of the motor. Since the motor generates a lot of heat during operation, the sound insulation cover reduces the heat dissipation rate of the motor, which can easily cause the motor temperature to be too high and damage it, affecting the normal use of the motor and reducing the service life of the motor.

[0025] Please see Figure 1-4This utility model provides a technical solution: a soundproof cover for a cement mill, including a mounting base plate 1 and a soundproof cooling device. A roller 2 is rotatably mounted on the top of the mounting base plate 1, and a large gear 3 is fixedly mounted on the right end of the roller 2. A mounting bracket 4 is fixedly connected to the top of the mounting base plate 1, and a drive motor 5 is fixedly mounted inside the mounting bracket 4. A rotating shaft 6 is fixedly connected to the output end of the drive motor 5. A support frame 7 is fixedly connected to the top of the mounting base plate 1. The end of the rotating shaft 6 away from the drive motor 5 is rotatably connected to the surface of the support frame 7. A small gear 8 is fixedly sleeved on the surface of the rotating shaft 6, and the small gear 8 meshes with the large gear 3. The soundproof cooling device includes an annular soundproof cover 9, heat dissipation fins 10, a spiral guide pipe 11, a return pipe 12, and a water storage tank 13. The annular soundproof cover 9 is fixedly connected to the mounting base plate 1. Inside the mounting bracket 4, an annular soundproof cover 9 is fitted onto the surface of the drive motor 5. Heat dissipation fins 10 are fixedly connected in a circular, equidistant manner to the outer surface of the annular soundproof cover 9. A spiral guide pipe 11 is fixedly connected inside the annular soundproof cover 9. A return pipe 12 is fixedly installed at the right end of the spiral guide pipe 11. A water storage tank 13 is fixedly connected to the top of the mounting base plate 1. The end of the return pipe 12 away from the spiral guide pipe 11 extends into the interior of the water storage tank 13. A water pump 14 is fixedly installed on the top of the water storage tank 13. A water pump pipe 15 is fixedly installed at the water pump 14's pumping end. The end of the water pump pipe 15 away from the water pump 14 extends into the interior of the water storage tank 13. A drain pipe 16 is fixedly installed at the water pump 14's draining end. The end of the drain pipe 16 away from the water pump 14 is fixedly installed at the left end of the spiral guide pipe 11.

[0026] After the staff starts the drive motor 5, the output end of the drive motor 5 rotates, which drives the rotating shaft 6 to rotate. The rotating shaft 6 rotates, which drives the small gear 8 to rotate. The small gear 8 rotates, which drives the large gear 3 to rotate. The top of the drum 2 is fixedly connected to the feed pipe. The staff can pour cement into the inside of the drum 2 through the feed pipe. When the large gear 3 rotates, it can drive the drum 2 to rotate and grind the cement raw materials inside.

[0027] During operation, the annular soundproof cover 9 covers the surface of the drive motor 5, reducing the noise generated by the drive motor 5. The heat generated by the drive motor 5 is conducted to the surface of the annular soundproof cover 9, which then dissipates heat to the outside through multiple heat dissipation fins 10, accelerating heat dissipation. After the operator starts the water pump 14, the pump 14 draws water stored in the water tank 13 through the pump pipe 15 and discharges it into the spiral guide pipe 11 through the drain pipe 16. Cooling water enters the spiral guide pipe 11. The cooling water flows in a spiral pattern inside the guide pipe 11 and the annular soundproof cover 9. After flowing to the right end, the cooling water returns to the water storage tank 13 through the return pipe 12. The cooling water accelerates the heat dissipation of the annular soundproof cover 9, thereby accelerating the diffusion of heat from the inside of the annular soundproof cover 9 to the outside. This prevents the surface temperature of the drive motor 5 from becoming too high. Furthermore, the multiple heat dissipation fins 10 can further accelerate the heat dissipation of the annular soundproof cover 9, thereby preventing the drive motor 5 from overheating and causing damage. This ensures the normal operation of the drive motor 5 and extends its service life.
