Description

Technical Field

[0001] This utility model relates to the field of refractory material production technology, and in particular to a fine grinding device for refractory material production. Background Technology

[0002] In the field of refractory material production, fine grinding is a key process for improving material properties (such as density and high-temperature strength). Currently, ball mills, as traditional and widely used grinding equipment, are extensively used in refractory material grinding operations due to their simple structure and strong applicability. However, when using a ball mill for grinding, it is inconvenient to pre-crush large pieces of refractory materials. Specifically, if large pieces of refractory materials, such as corundum, magnesia, or recycled materials like waste refractory bricks, are directly fed into the ball mill, the large materials are difficult to be quickly and efficiently crushed by the grinding media due to the limitations of the ball mill's structure and working principle. Moreover, large materials can easily cause the ball mill to "stalle," meaning a sudden increase in mill load, affecting equipment stability and even damaging components such as the motor. Large materials need to be repeatedly impacted by the grinding media within the ball mill to be crushed, which greatly prolongs the grinding time, reduces production efficiency, and causes a large waste of energy. Furthermore, in the subsequent fine grinding stage, more energy is consumed in the ineffective idling of the media, making it difficult to achieve the fine grinding requirements of refractory materials. At the same time, large materials may also aggravate the wear of the ball mill liner and grinding media, shorten the equipment's service life, and increase production costs. Therefore, this utility model proposes a fine grinding device for refractory material production to solve the above problems. Summary of the Invention

[0003] To address the aforementioned problems, this utility model proposes a fine grinding device for refractory material production, which solves the problem that existing technologies using ball mills for grinding are inconvenient for pre-crushing large pieces of refractory material.

[0004] To achieve the purpose of this utility model, the utility model is implemented through the following technical solution: a fine grinding device for refractory material production, including a mounting frame, a power component installed at one end of the top of the mounting frame, a ball mill body installed above the mounting frame, a feed inlet opened above the ball mill body, a support column installed at the top of the mounting frame, a mounting plate installed at the top of the support column, the mounting plate being positioned above the feed inlet, a pre-crushing mechanism being positioned above the mounting plate, a screening mechanism being positioned at the bottom of the pre-crushing mechanism, and a feed chamber being installed at the middle position of the mounting plate; The pre-crushing mechanism includes a crushing chamber, a feeding port, a discharging port, a fixed frame, a servo motor, a driving gear, a driven gear, a crushing shaft, and crushing teeth. The crushing chamber is installed on the top of the mounting plate. The feeding port is installed at the top of the crushing chamber, and the discharging port is installed at the bottom of the crushing chamber. A fixed frame is installed at one end of the crushing chamber, and a servo motor is installed at one end of the fixed frame. A driving gear is installed inside the fixed frame, and the output end of the servo motor is connected to one end of the driving gear. A driven gear meshes with one end of the driving gear. A crushing shaft is installed inside the crushing chamber, and one end of the crushing shaft is connected to one end of both the driving gear and the driven gear. Crushing teeth are provided on the outer wall of the crushing shaft.

[0005] A further improvement is that multiple crushing teeth are provided on the outer side wall of the crushing shaft, and the multiple crushing teeth are distributed at equal intervals on the outer side wall of the crushing shaft.

[0006] A further improvement is made in that: the screening mechanism includes a damper, a telescopic spring, a screening frame, and a vibration motor. The damper is installed on the top of the mounting plate, the outer side wall of the damper is provided with a telescopic spring, the top of the damper is installed with a screening frame, and the front end of the screening frame is installed with a vibration motor.

[0007] A further improvement is that the screening frame is designed to be inclined, and guide plates are installed at both ends of the bottom of the screening frame, and the guide plates are designed to be inclined.

[0008] A further improvement is that a feeding plate is installed on one side of the top of the mounting plate, and the feeding plate is located on one side of the screening frame.

[0009] A further improvement is that the inside of the feeding plate is inclined, which facilitates material feeding.

[0010] The beneficial effects of this utility model are as follows: Through the pre-crushing mechanism above the mounting plate, utilizing the interaction between the crushing chamber, feeding port, discharging port, fixed frame, servo motor, driving gear, driven gear, crushing shaft, and crushing teeth of the pre-crushing mechanism, large pieces of refractory material can be pre-crushed into small pieces suitable for ball mill processing. This effectively avoids ball mill "stalling," ensures stable equipment operation, extends the service life of key components such as motors and liners, significantly reduces grinding time within the ball mill, improves grinding efficiency, reduces energy consumption, and allows the ball mill to focus on medium and fine grinding, improving the grinding precision of refractory materials, ensuring product quality, and reducing equipment maintenance costs and raw material waste during production. Furthermore, by incorporating a screening mechanism, utilizing the interaction between the damper, telescopic spring, screening frame, and vibration motor of the screening mechanism, large impurities and excessive particles in the refractory material can be pre-filtered, preventing them from entering the ball mill and causing equipment jamming or excessive wear, ensuring stable grinding, reducing ineffective grinding load, improving subsequent ball mill efficiency, and reducing the impact of impurities on the purity of the refractory material.

[0013] To deepen the understanding of this utility model, the following detailed description will be provided in conjunction with embodiments. These embodiments are only used to explain this utility model and do not constitute a limitation on the scope of protection of this utility model.

[0014] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a fine grinding device for refractory material production, including a mounting frame 1. A power assembly 2 is installed at one end of the top of the mounting frame 1. A ball mill body 3 is installed above the mounting frame 1. A feed inlet 4 is opened above the ball mill body 3. A support column 5 is installed at the top of the mounting frame 1. An mounting plate 6 is installed at the top of the support column 5. The mounting plate 6 is located above the feed inlet 4. A pre-crushing mechanism is provided above the mounting plate 6. A screening mechanism is provided at the bottom of the pre-crushing mechanism. A feed chamber 22 is installed at the middle position of the mounting plate 6.

[0015] The pre-crushing mechanism includes a crushing chamber 7, a feeding port 8, a discharging port 9, a fixed frame 10, a servo motor 11, a driving gear 12, a driven gear 13, a crushing shaft 14, and crushing teeth 15. The crushing chamber 7 is mounted on the top of the mounting plate 6. The feeding port 8 is mounted on the top of the crushing chamber 7, and the discharging port 9 is mounted on the bottom of the crushing chamber 7. The fixed frame 10 is mounted on one end of the crushing chamber 7, and the servo motor 11 is mounted on one end of the fixed frame 10. The driving gear 12 is mounted inside the fixed frame 10, and the output end of the servo motor 11 is connected to one end of the driving gear 12. The driven gear 13 meshes with one end of the driving gear 12. The crushing shaft 14 is mounted inside the crushing chamber 7, and one end of the crushing shaft 14 is connected to one end of the driving gear 12 and the driven gear 13, respectively. Crushing teeth 15 are provided on the outer wall of the crushing shaft 14. Multiple crushing teeth 15 are provided on the side wall, and are evenly distributed on the outer side wall of the crushing shaft 14. In use, refractory material is poured into the crushing chamber 7 through the feed port 8. At this time, the servo motor 11 is started to drive the drive gear 12 to rotate. Since the drive gear 12 and the driven gear 13 mesh with each other, the drive gear 12 and the driven gear 13 are used to drive the crushing shaft 14 to rotate, and then the crushing teeth 15 are used to crush the refractory material. Large pieces of refractory material can be pre-crushed into small pieces suitable for ball mill processing, effectively avoiding the ball mill "stalling", ensuring stable operation of the equipment, extending the service life of key components such as motors and liners, and significantly reducing the grinding time in the ball mill, improving grinding efficiency, reducing energy consumption, and allowing the ball mill to focus on medium and fine grinding, improving the grinding fineness of refractory materials, ensuring product quality, and reducing equipment maintenance costs and raw material waste in the production process.

[0016] The screening mechanism includes a damper 16, a telescopic spring 17, a screening frame 18, and a vibration motor 19. The damper 16 is installed on the top of the mounting plate 6. The telescopic spring 17 is provided on the outer side wall of the damper 16. The screening frame 18 is installed on the top of the damper 16. The vibration motor 19 is installed at the front end of the screening frame 18. In use, the crushed refractory material falls above the screening frame 18 through the feed port 9. At this time, the vibration motor 19 is started. With the cooperation of the damper 16 and the telescopic spring 17, the refractory material is screened. The refractory material that passes through is guided by the guide plate 21 and enters the interior of the ball mill body 3 through the feed chamber 22. The refractory material that does not pass through rolls down the screening frame 18 into the interior of the feed plate 20 for discharge. This can pre-filter large impurities and excessive particles in the refractory material, preventing them from entering the ball mill and causing equipment jamming or excessive wear, ensuring stable grinding, reducing ineffective grinding load, improving subsequent ball mill efficiency, and reducing the impact of impurities on the purity of the refractory material.

[0017] The screening frame 18 is designed with an inclination, and guide plates 21 are installed at both ends of the bottom of the screening frame 18. The guide plates 21 are designed with an inclination, and the use of guide plates 21 makes the refractory material feeding more efficient.

[0018] A feeding plate 20 is installed on one side of the top of the mounting plate 6. The feeding plate 20 is located on one side of the screening frame 18. The interior of the feeding plate 20 is inclined. The feeding plate 20 can facilitate feeding and improve the feeding efficiency of refractory materials that have not passed the screening.

[0019] Working principle: The operator first pours the refractory material into the crushing chamber 7 through the feed port 8. At this time, the servo motor 11 is started to drive the drive gear 12 to rotate. Since the drive gear 12 and the driven gear 13 mesh with each other, the crushing shaft 14 is driven to rotate by the mutual cooperation between the drive gear 12 and the driven gear 13. Then, the crushing teeth 15 crush the refractory material. The crushed refractory material falls above the screening frame 18 through the discharge port 9. At this time, the vibration motor 19 is started. With the cooperation of the damper 16 and the extension spring 17, the refractory material is screened. The refractory material that passes through is guided by the guide plate 21 and enters the ball mill body 3 through the feed chamber 22. The ball mill body 3 is used to finely grind the refractory material. The refractory material that does not pass through rolls down the screening frame 18 into the discharge plate 20 for discharge.
