[0002] In the production process of silicate cement clinker, the grinding process is crucial, as it directly affects the fineness and quality of the cement clinker. However, existing silicate cement clinker grinding equipment has many problems.

[0003] On the one hand, traditional grinding equipment is not in a sealed state during operation, which makes it easy for the powder produced by grinding to spread into the surrounding environment. This not only wastes raw materials and increases production costs, but also poses a threat to the working environment and the health of operators. Powder spreading into the air may cause respiratory diseases and other health problems.

[0004] On the other hand, after grinding, a large amount of powder often remains inside the equipment, making the cleaning process tedious and difficult. Currently, there is no effective structure to achieve self-cleaning of the equipment, which requires manual cleaning, which is extremely labor-intensive and time-consuming. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a high-efficiency grinding equipment for silicate cement clinker. This equipment is sealed during grinding to prevent powder diffusion. In addition, it is equipped with a re-drying structure after grinding, which enables the equipment to self-clean.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figures 1-3 A high-efficiency grinding equipment for silicate cement clinker includes a shell 1, and a discharge port 15 is provided at the bottom of the inner side of the shell 1;

[0023] The system also includes a grinding mechanism, which consists of mounting strips 13 installed between the inner walls of the left and right sides of the housing 1. A second motor 19 is mounted on the upper end of the mounting strips 13. The output shaft of the second motor 19 passes through the mounting strips 13 and is fixedly connected to a grinding column 14. The lower end of the grinding column 14 is conical and fits into the inner wall of the housing 1. Both the inner wall of the housing 1 and the inner side of the lower end of the grinding column 14 are provided with grinding texture layers. Multiple stirring strips 6 are fixedly connected to the outer side of the grinding column 14. The gap between the outer side of the lower part of the grinding column 14 and the inner wall of the housing 1 gradually decreases. With the rotation of the grinding texture layer, the grinding operation can be realized. The rotation of the multiple stirring strips 6 can make the powder evenly distributed in the gap, ensuring the uniformity of grinding and avoiding the situation where the powder is concentrated on one side, which would reduce the grinding efficiency. In use, the powder is first poured into the gap between the outer wall of the grinding column 14 and the housing 1 inside the housing 1, with the powder height lower than the mounting strips 13.

[0024] It also includes a collection mechanism for collecting grinding powder. The collection mechanism includes a collection box 12 placed on the ground, and a collection port 16 is provided at the upper end of the collection box 12. The upper end of the collection port 16 is in contact with the lower end of the discharge port 15.

[0025] The device also includes a sealing mechanism for sealing the upper surface of the housing 1. The sealing mechanism includes a connecting strip 2 fixedly connected to the left side of the housing 1. A groove 3 is provided on the right side of the connecting strip 2. A threaded rod 4 is rotatably connected between the upper and lower inner walls of the groove 3. A slider 7 is threadedly connected to the threaded rod 4. The slider 7 is slidably connected to the inner wall of the groove 3. A sealing cover 8 is fixedly connected to the right side of the slider 7. A first motor 5 is installed at the upper end of the connecting strip 2. The output shaft of the first motor 5 extends into the groove 3 and is fixedly connected to the upper end of the threaded rod 4.

[0026] The upper end of the sealing cover 8 is equipped with an air pump 9 and a liquid pump 10. The air outlet of the air pump 9 and the liquid outlet of the liquid pump 10 are connected by a connecting pipe 11. A hollow ring 17 is installed on the inner top of the sealing cover 8. The other end of the connecting pipe 11 is connected to the hollow ring 17. A nozzle 18 is opened at the inner bottom of the hollow ring 17. Furthermore, the liquid inlet of the liquid pump 10 is connected to an external water tank.

[0027] In this invention, the silicate cement clinker powder to be ground is poured into the interior of the housing 1, placing it in the gap between the outer wall of the grinding column 14 and the inner wall of the housing 1. The height of the powder is lower than the mounting strip 13. The first motor 5 is started, and the output shaft of the first motor 5 drives the threaded rod 4 to rotate. Since the slider 7 is threadedly connected to the threaded rod 4 and slidably connected to the inner wall of the slide groove 3, the rotation of the threaded rod 4 causes the slider 7 to move downward along the slide groove 3, thereby driving the sealing cover 8 to move downward until the sealing cover 8 completely covers the upper end surface of the housing 1, achieving a sealing treatment of the upper end surface of the housing 1 and preventing powder diffusion during the grinding process. The second motor 19 is started, and the output shaft of the second motor 19 drives the grinding column 14 to rotate. The lower end of the grinding column 14 is conical and fits with the inner wall of the housing 1. The grinding texture layers on the surfaces of the two rub against each other, and at the same time, the gap between the outer side of the lower end of the grinding column 14 and the inner wall of the housing 1 becomes smaller and smaller, thus grinding the powder. In addition, multiple stirring strips 6 on the outside of the grinding column 14 rotate with the grinding column 14, so that the powder is evenly distributed in the grinding gap, ensuring the uniformity of grinding, avoiding the powder from concentrating on one side, and improving the grinding efficiency. The ground powder is discharged from the discharge port 15 at the bottom of the housing 1 and falls into the collection box 12 placed on the ground below. The collection port 16 at the upper end of the collection box 12 contacts the lower end of the discharge port 15 to ensure that the powder is collected smoothly. The contact between the two can prevent the powder from spreading during discharge. When the grinding work is completed, stop pouring powder into the housing 1 and turn off the second motor 19 to stop the grinding column 14 from rotating.

[0028] When cleaning is required, in a sealed state, remove the collection box 12, start the liquid pump 10, the liquid pump 10 draws liquid from the external water tank, the liquid enters the hollow ring 17 through the connecting pipe 11, and then sprays out from the nozzle 18 to rinse the inside of the housing 1, further removing residual powder and impurities. The rinsed wastewater is discharged from the discharge port 15. After rinsing is completed, turn off the liquid pump 10 and start the air pump 9. The air pump 9 pumps gas into the connecting pipe 11, and then delivers it to the hollow ring 17 through the connecting pipe 11. Finally, it is sprayed out from the nozzle 18 at the bottom of the hollow ring 17. Because it is sealed by the sealing cover 8, the discharged gas will eventually be discharged from the discharge port 15 along the grinding gap, achieving the purpose of drying and avoiding the situation where residual water corrodes the inner wall of the housing 1, thus realizing the self-cleaning step.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
