Description

Technical Field

[0001] This utility model belongs to the field of ball mill protection technology, and in particular relates to a protective device for ball mills. Background Technology

[0002] A ball mill is a key industrial piece of equipment used for crushing or mixing materials. It is commonly used in industries such as mining, metallurgy, chemicals, and building materials. Its working principle is based on a rotating cylinder filled with steel balls or other grinding media. As the cylinder rotates, these media are lifted to a certain height and then fall, impacting, squeezing, and grinding the materials entering the cylinder, ultimately achieving fine crushing of the materials. Ball mills are known for their high efficiency, large throughput, adaptability to various material types, and ease of operation. They are suitable for various needs from laboratory scale to large-scale industrial production and are an indispensable and important device in modern industrial production processes.

[0003] The problem with existing technology is that the protective devices of existing equipment are usually fixed or have a complex detachable design. This means that when carrying out equipment inspection or routine maintenance, staff have to spend a lot of time disassembling and reinstalling the protective devices. This design not only significantly reduces the efficiency of maintenance work, but may also introduce additional safety risks due to the complexity of the operation process. Utility Model Content

[0023] refer to Figure 1 and Figure 2 The first protective cover 5 has a connecting groove 6 on its right side. The second protective cover 7 is placed inside the connecting groove 6. The second protective cover 7 is slidably connected to the inside of the connecting groove 6. The first protective cover 5 has two through grooves 8 on its front side. The first protective cover 5 has a receiving block 9 placed on its front side. The upper and lower sides of the rear surface of the receiving block 9 are slidably connected to the inside of the through grooves 8. The rear side of the receiving block 9 is fixedly connected to the front side of the second protective cover 7.

[0024] By adopting the above solution, the second protective cover 7 can be set up to enable flexible opening and closing of the feeding position, which improves the convenience of material addition and work efficiency while ensuring operational safety.

[0025] refer to Figure 3 The receiving block 9 has a receiving groove 10 inside. A spring 11 is fixedly connected to the front side of the receiving groove 10. A connecting plate 12 is fixedly connected to the rear side of the spring 11. A fixing rod 13 is fixedly connected to the rear side of the connecting plate 12. The rear end of the fixing rod 13 passes through and extends out of the rear side of the receiving block 9. Fixing holes 14 are provided on both the left and right sides of the front surface of the first protective cover 5. The fixing holes 14 are used in conjunction with the fixing rod 13.

[0026] By adopting the above solution, the second protective cover 7 can be conveniently fixed and quickly unlocked by setting the fixing rod 13 and the spring 11, thereby effectively improving the safety of equipment operation.

[0027] refer to Figure 3 Stabilizing rods 15 are placed on both the upper and lower sides inside the receiving groove 10. The front and rear ends of the stabilizing rods 15 are fixedly connected to the surface of the receiving groove 10. The upper and lower sides of the connecting plate 12 are slidably connected to the surface of the stabilizing rods 15.

[0028] By adopting the above solution, by setting the stabilizer bar 15, the precise guidance and stable operation of the connecting plate 12 during the movement can be ensured, and the deviation that occurs during the movement can be effectively prevented.

[0029] refer to Figure 3 A pull rod 16 is fixedly connected to the front side of the connecting plate 12, and the front end of the pull rod 16 passes through and extends out of the front side of the receiving block 9.

[0030] By adopting the above solution, the operator can easily control the movement of the connecting plate 12 and the fixing rod 13 by setting the pull rod 16, so as to quickly lock and unlock the second protective cover 7, thereby improving the convenience of operation and work efficiency.

[0031] refer to Figure 1 and Figure 4 A fixing plate 17 is fixedly connected to the top left side of the base plate 1. A groove 18 is provided inside the fixing plate 17. A gear 19 is placed inside the groove 18. The right side of the gear 19 is rotatably connected to the right side of the groove 18. A rack 20 is placed on both the upper and lower sides of the gear 19. The right side of the rack 20 is slidably connected to the right side of the groove 18. The rack 20 is meshed with the gear 19. The left side of the gear 19 passes through and extends out of the left side of the fixing plate 17. A rotating handle 21 is fixedly connected to the left side of the gear 19.

[0032] By adopting the above scheme, the synchronous adjustment of the limit rod 22 can be achieved by setting gear 19 and rack 20, making the disassembly and installation of the first protective cover 5 more convenient and efficient, and significantly improving the operational convenience and work efficiency of equipment maintenance.

[0033] refer to Figure 1 and Figure 4 Limiting rods 22 are fixedly connected to the sides of the racks 20 that are far apart from each other. The ends of the limiting rods 22 that are far apart from each other penetrate through and extend out of the surface of the fixing plate 17. Limiting frames 23 are fixedly connected to the front and rear sides of the left surface of the first protective cover 5. The limiting frames 23 are used in conjunction with the limiting rods 22.

[0034] By adopting the above solution, the first protective cover 5 can be securely locked after installation by setting the limit rod 22, effectively preventing loosening or accidental detachment, and improving the safety and stability of equipment operation.

[0035] The working principle of this utility model:

[0036] In use, first use the pull rod 16 to pull the connecting plate 12 forward. The connecting plate 12 drives the fixing rod 13 to move. After the fixing rod 13 moves out of the fixing hole 14, move the second protective cover 7 to the left along the connecting groove 6. After the second protective cover 7 opens, add the material into the ball mill body 2. Then reset the second protective cover 7 and release the pull rod 16. At this time, the spring 11 will cause the fixing rod 13 to insert into the fixing hole 14. After confirming that the second protective cover 7 is firmly closed, the ball mill body 2 can be started for subsequent grinding. When it is necessary to perform daily inspections on the ball mill body 2... During maintenance, the first protective cover 5 must be removed for inspection. To remove it, first use the handle 21 to rotate the gear 19. The gear 19 drives the racks 20 on both sides to move in the opposite direction. Then the racks 20 drive the limit rod 22 to move. When the limit rod 22 moves out of the limit frame 23, the fixed state of the first protective cover 5 is released. Then it is removed along the slide groove 4 for subsequent inspection or maintenance. After maintenance, the first protective cover 5 is slid back into the slide groove 4, and the handle 21 is operated in the opposite direction to make the limit rod 22 re-insert into the limit frame 23 to complete the fixation.

[0037] In summary, this protective device for a ball mill, through the coordinated use of a base plate 1, a ball mill body 2, mounting holes 3, a sliding groove 4, a first protective cover 5, a connecting groove 6, a second protective cover 7, a through groove 8, a receiving block 9, a receiving groove 10, a spring 11, a connecting plate 12, a fixing rod 13, a fixing hole 14, a stabilizing rod 15, a pull rod 16, a fixing plate 17, a groove 18, a gear 19, a rack 20, a rotating handle 21, a limiting rod 22, and a limiting frame 23, solves the problem that existing protective devices typically employ fixed or complex detachable designs. This design forces workers to spend considerable time disassembling and reinstalling the protective device during equipment inspection or routine maintenance, significantly reducing maintenance efficiency and potentially introducing additional safety risks due to the complexity of the operating procedures.
