Abstract
Description
Technical Field
[0001] This utility model relates to the field of refractory material processing technology, specifically to a screening device for refractory materials. Background Technology
[0002] Refractory materials are used in various sectors of the national economy, including steel, non-ferrous metals, glass, cement, ceramics, petrochemicals, machinery, boilers, light industry, power, and military industry. They are essential basic materials for ensuring the production, operation, and technological development of these industries, and play an irreplaceable and important role in the development of high-temperature industrial production.
[0003] A search revealed that the announcement number CN219210597U, entitled "A Screening Device for Producing Refractory Materials," includes a screening box. Research and analysis showed that this device uses a vibrating motor to drive the screening box to vibrate. After screening, the refractory raw materials are separated by a screening frame. The screened materials pass through a discharge port and a guide plate into a collection box, where they are discharged through a discharge pipe for collection. Materials entering the bottom of the screening tube pass through a triangular block and enter the collection box through a discharge pipe. This allows for the grading and screening of refractory materials of different particle sizes for subsequent use, and the collection and discharge of materials of different particle sizes makes it more convenient to use. However, it also has some drawbacks.
[0004] For example, this equipment cannot process large pieces of material during use. If large pieces enter the equipment, it will not only affect the screening of the material, but also cause material to be trapped inside. This would require additional equipment to process them. Furthermore, it does not have the function of cleaning the surface of the screening components during use. After long-term use, the components are prone to blockage by material, which can affect the screening of the components. In order to solve the above technical problems, we have designed a screening device for refractory materials. Utility Model Content

[0020] Please see Figures 1-4 A screening device for refractory materials includes a housing 1, a screening box 2 movably installed inside the housing 1, a screening plate 3 fixedly installed inside the screening box 2, sliding blocks 9 fixedly installed on both sides of the screening box 2, a feeding mechanism 6 provided on the top of the housing 1, cleaning mechanisms 7 provided on both sides of the top of the housing 1, a movable box 10 movably installed at the bottom of the inner cavity of the housing 1, a drive motor 8 fixedly installed on the left side of the housing 1, placement frames 4 fixedly installed on both sides of the housing 1, and a collection box 5 movably installed inside the placement frame 4. The feeding mechanism 6 includes a feeding pipe 13 connected to and installed on the top of the housing 1, and the cleaning mechanism 7 includes a fixed shell 17 fixedly installed on the top of the housing 1. The placement frames 4 facilitate the placement of the collection box 5 so that the collection box 5 can collect the screened material.
[0021] Please see Figure 1 and Figure 4 There are two fixed housings 17. A second servo motor 18 is fixedly installed on the front side of the fixed housing 17. The output end of the second servo motor 18 passes through the inner cavity of the fixed housing 17 and is fixedly connected to a threaded rod 19.
[0022] Please see Figure 4 The threaded rod 19 is threaded with a threaded plate 20. The bottom of the threaded plate 20 extends into the inner cavity of the housing 1 and is fixedly connected to a cleaning brush plate 21. By setting the threaded plate 20, it is easy for the threaded plate 20 to drive the cleaning brush plate 21 to move.
[0023] Please see Figure 1 , Figure 2 and Figure 3 A first servo motor 14 is fixedly installed on the left side of the feed pipe 13. The output end of the first servo motor 14 passes through the inner cavity of the feed pipe 13 and is fixedly connected to a crushing shaft 15. Crushing blades 16 are fixedly connected to both the front and rear sides of the inner cavity of the feed pipe 13. By setting the crushing blades 16, they can cooperate with the crushing shaft 15 to crush the material.
[0024] Please see Figure 2 The output end of the second servo motor 18 is fixedly connected to a rotating disk 11. A connecting rod 12 is fixedly installed on the rear side of the rotating disk 11 via a rotating shaft. The connecting rod 12 is fixedly connected to the sliding block 9 via the rotating shaft. Through the cooperation of the rotating disk 11 and the connecting rod 12, the sliding block 9 can be easily driven to slide, so that the sliding block 9 can drive the screening box 2 to vibrate and screen.
[0025] Please see Figure 1 and Figure 2 The box body 1 has sliding holes on both sides and conveying holes on both sides. There are two screening plates 3. The opposite sides of the two screening plates 3 pass through the conveying holes and extend into the inner cavity of the placement frame 4. By setting the sliding holes, the sliding block 9 can slide back and forth so that the drive motor 8 can drive the screening box 2 to move.
[0026] Please see Figure 1 and Figure 2 Support legs are fixedly installed on the bottom of both sides of the box 1, and guide blocks are fixedly installed on both sides of the bottom of the screening box 2. By setting the guide blocks, the material can be guided so that the material falls from the screening box 2.
[0027] During use, the user feeds the refractory material into the equipment through the feed pipe 13. While feeding the refractory material, the user starts the first servo motor 14, causing its output to drive the crushing shaft 15 to rotate. This allows the crushing shaft 15 to work in conjunction with the crushing blades 16 to crush the refractory material, preventing large pieces from entering the equipment. The material falls onto the screening plate 3 after entering the equipment. Then, the user starts the drive motor 8, causing its output to drive the connecting rod 1 through the rotating disk 11. 2. Rotate the connecting rod 12 so that it can drive the screening box 2 to vibrate through the sliding block 9, thereby ensuring that the screening plate 3 can vibrate and screen the material. During screening, the screening plate 3 will also guide the screened material into the collection box 5. During long-term use, the user can periodically operate the second servo motor 18 so that the output end of the second servo motor 18 can drive the threaded plate 20 to move through the threaded rod 19. When the threaded plate 20 moves, it will drive the cleaning brush plate 21 to clean the surface of the screening plate 3 to prevent material from clogging the screening plate 3.
[0028] In summary, this refractory material screening equipment, through the cooperation of the housing 1, screening box 2, screening plate 3, placement frame 4, collection box 5, feeding mechanism 6, cleaning mechanism 7, drive motor 8, sliding block 9, and movable box 10, solves the problems of being unable to process large pieces of material, which easily affect the screening process, and lacking the function of cleaning the surface of the screening components, which can easily cause material to clog the components and affect the screening process.
