Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, specifically a raw material mixing and grinding device for refractory materials. Background Technology

[0002] In the production and preparation of refractory materials, the mixing and grinding of raw materials is one of the key processes that determines the performance of the product. Its core is to use a mill to crush, grind and mix various block and granular refractory raw materials to achieve uniform particle size and homogenization of composition, laying the foundation for subsequent molding, sintering and other processes.

[0003] Currently, most refractory material raw material mixing and grinding devices commonly used in the industry adopt an open or semi-open structure, mainly consisting of a grinding wheel, a grinding disc, a transmission mechanism, and a frame. During operation, the grinding wheel rotates on the grinding disc, and the raw materials are ground and mixed by the extrusion and friction between the grinding wheel and the grinding disc.

[0004] However, such equipment still has certain defects in actual operation. Refractory raw materials, such as corundum, mullite, and silicon carbide, generate dust during the grinding process. Due to the lack of effective sealing or dustproof structures in the equipment, this dust will diffuse into the workshop air with the airflow generated by the rotation of the grinding wheel, which not only seriously pollutes the production environment but can also be inhaled by operators, endangering their respiratory health. At the same time, some refractory raw materials are initially in a blocky state. Under the violent crushing action of the grinding wheel, these blocky raw materials will instantly break and generate high-speed flying fragments. The flying fragments may pose a personal safety hazard to on-site operators. In addition, the flying fragments cannot participate in the subsequent mixing process, which will also cause waste of raw materials. In order to address the above problems, we provide a raw material mixing and grinding device for refractory materials to solve the problems mentioned above. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-3In this embodiment of the present invention, a raw material mixing and grinding device for refractory materials includes a grinding basin 1. A supporting base 10 is fixedly connected to the lower end of the grinding basin 1. A grinding mechanism for grinding materials is provided inside the grinding basin 1. The grinding mechanism includes a hollow cone 18, which is fixedly connected to the middle of the lower end face of the grinding basin 1. A central shaft 19 is rotatably connected to the middle of the hollow cone 18. A top block 16 is fixedly connected to the upper end of the central shaft 19. Both ends of the top block 16 are rotatably connected to adapters 22. Grinding wheels 20 are rotatably connected to the ends of the adapters 22. Both sides of block 16 are fixedly connected to mounting brackets, and the lower ends of the mounting brackets are fixedly connected to scrapers 17. The support base 10 is equipped with a drive assembly for driving the central shaft 19 to rotate. When the central shaft 19 rotates, the top block 16 fixed at its upper end rotates together. Since the grinding wheel 20 is rotatably connected to both ends of the top block 16, the outer circle of the grinding wheel 20 is in close contact with the bottom of the grinding basin 1. When the top block 16 rotates, it drives the grinding wheel 20 to revolve. At the same time, the grinding wheel 20 is subjected to the friction force of the inner wall of the grinding basin 1 and rotates around its own axis, thereby forming a crushing action on the material in the grinding basin 1.

[0026] Please see Figure 2 The drive assembly includes a reducer 14, which is fixedly connected to the bottom horizontal plate of the support base 10. The output shaft of the reducer 14 is connected to the lower end of the central shaft 19. A drive motor 12 is fixedly connected to one side of the lower end of the support base 10. Pulleys 15 are mounted on both the output shaft of the drive motor 12 and the input shaft of the reducer 14. A transmission belt 13 is installed between the two pulleys 15. During driving, the drive motor 12 drives the pulleys 15 to rotate. Through the transmission belt 13, the power is transmitted to the pulleys 15 on the input shaft of the reducer 14, thus realizing the transmission of power. After the reducer 14 reduces the speed and increases the torque of the input high-speed power, it transmits the appropriate speed and torque to the central shaft 19 through the output shaft to drive the central shaft 19 to rotate circumferentially.

[0027] Please see Figure 1 and Figure 2The grinding basin 1 has a liquid inlet connector 11 on one side, which facilitates connection to a water source for subsequent water filling and allows for regular manual cleaning of the inside of the grinding basin 1. The grinding basin 1 also has a discharge assembly at its lower other side, comprising a discharge hopper 8 fixedly connected to the bottom of one side of the grinding basin 1. A discharge port is located inside the discharge hopper 8 in the grinding basin 1, and a sealing plate 23 is installed inside the discharge port. The sealing plate 23 is rotatably connected to the bottom of the grinding basin 1 via a rotating support. A U-shaped block 25 is fixedly connected to the end of the sealing plate 23. The grinding basin 1 is located... A threaded post 24 is rotatably connected above the U-shaped block 25. A threaded handle 9 is threadedly connected to the threaded post 24 for fixing the closing plate 23 in conjunction with the U-shaped block 25. During material discharge, the threaded handle 9 is first loosened, and then the threaded post 24 is turned out from inside the U-shaped block 25 to release the lock on the closing plate 23. The closing plate 23 can then be opened, and the material is discharged simultaneously with the rotating scraper 17. After the material is discharged, the closing plate 23 is flipped over to close the discharge port. Then the threaded post 24 is flipped over so that it engages with the U-shaped block 25. After engagement, the threaded handle 9 is tightened to fix the closing plate 23.

[0028] Please see Figure 1 The grinding basin 1 is fixedly connected to one side of the upper end of the adapter seat 6. The adapter seat 6 is rotatably connected to the crank arm 5. The end of the crank arm 5 is fixedly connected to the cover body 4 for sealing the grinding basin 1. The lower end of the cover body 4 and the upper end of the grinding basin 1 are both provided with widened edges. The side of the widened edge at the lower end of the cover body 4 that is in contact with the grinding basin 1 is provided with a sealing ring. The support base 10 is provided with an opening and closing assembly for driving the crank arm 5 to open and close the cover body 4. The opening and closing assembly includes a cylinder 7. The cylinder 7 is rotatably connected to the support leg of the support base 10 near the adapter seat 6. The output end of the cylinder 7 is rotatably connected to the end of the crank arm 5 away from the cover body 4.

[0029] When the cover is opened, the output end of cylinder 7 retracts, pulling the crank arm 5 to rotate around the transition seat 6, causing the cover 4 to flip and open the opening of the grinding basin 1; when the cover is closed, the output end of cylinder 7 extends, pushing the crank arm 5 to rotate in the opposite direction around the transition seat 6, and the cover 4 flips and closes accordingly. After closing, the lower end of the cover 4 is fitted with the upper end of the grinding basin 1, and the sealing ring on the inner side of the cover edge fills the gap to complete the seal.

[0030] Please see Figure 1 and Figure 4The cover 4 is also provided with a feeding mechanism for adding material into the grinding basin 1; the feeding mechanism includes a feeding port 2, which is fixedly connected to the side of the cover 4 away from the curved arm 5, and the feeding port 2 communicates with the interior of the cover 4. A splash guard 21 is provided inside the feeding port 2, and rotating shafts are fixedly connected to both sides of the upper end of the splash guard 21, which is rotatably connected to the feeding port 2; the splash guard 21 is rotatably connected to the feeding port 2 via the rotating shafts on both sides. When no material is being added, the splash guard 21 is subjected to... The material remains vertical due to its own gravity, blocking the internal channel of the feeding port 2 and preventing the material in the grinding basin 1 from splashing to the outside due to grinding. When feeding, the material falls along the feeding port 2, and its own gravity exerts a downward force on the splash guard 21, pushing the splash guard 21 to rotate around the axis, opening the feeding channel, and the material smoothly enters the grinding basin 1. After feeding is completed, the force of the material on the splash guard 21 disappears, and the splash guard 21 returns to the vertical position again by its own gravity, blocking the feeding port 2 again.

[0031] Please see Figure 1 The upper end of the cover 4 is provided with an installation opening in the middle, which protrudes from the upper surface of the cover 4. A transparent observation plate 3 is fixedly connected inside the installation opening. Through the transparency of the transparent observation plate 3, the operator can directly observe the grinding state and mixing degree of the material in the grinding basin 1. At the same time, when too much dust adheres to the transparent observation plate 3 and affects the observation, the inside of the transparent observation plate 3 can be cleaned when the cover 4 is opened.

[0032] The working principle of this utility model is as follows: the drive motor 12 rotates and transmits power to the reducer 14 through the pulley 15 and the transmission belt 13. After the reducer reduces the speed and increases the torque, it drives the central shaft 19 to rotate. The central shaft 19 drives the top block 16 to rotate synchronously, so that the grinding wheel 20 revolves around the center of the grinding basin 1. At the same time, because the grinding wheel 20 is in contact with the bottom of the grinding basin 1, it rotates due to friction, thereby crushing the material. The scrapers 17 on both sides of the top block 16 scrape the bottom of the grinding basin 1 along with the revolution, thereby mixing the material.

[0033] When it is necessary to add material to the grinding basin 1, it can be added through the feeding port 2. When adding, the material falls along the feeding port 2, pushing the splash guard 21 to rotate around the shaft and open the channel, allowing the material to enter the grinding basin 1. After the material is added, the splash guard 21 returns to its original position by its own weight, blocking the feeding port 2 to prevent dust from drifting out and fragments from splashing. After grinding is completed, the threaded handle 9 can be loosened, and then the threaded column 24 can be turned out from the U-shaped block 25 to release the lock on the closing plate 23. Then the closing plate 23 can be opened, and the material can be discharged at the same time with the rotating scraper 17.

[0034] When the cover 4 needs to be opened, the cylinder 7 retracts, pulling the crank arm 5 to rotate around the transition seat 6, causing the cover 4 to flip open, which facilitates cleaning or maintenance of the inside of the grinding basin 1. When the cover 4 is closed, the cylinder extends, pushing the crank arm 5 to rotate in the opposite direction, and the cover 4 closes. Its widened edge fits against the edge of the grinding basin, and the sealing ring fills the gap to complete the seal.

[0035] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Although this specification describes embodiments, not every embodiment contains only one technical solution. This method of description is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
