Description

Technical Field

[0001] This application relates to a novel detachable turntable structure, belonging to the field of grinding mill technology. Background Technology

[0002] The grinding mill turntable is the core component. Its function is to drive the grinding rollers to move within a ring track through rotation, causing the material to disperse to the periphery under centrifugal force and fall into the grinding chamber. After being pressed, rolled, and ground by the grinding rollers, the material is ground. Traditional turntables use an integrated casting process and are made of 45# cast steel, which is generally suitable. However, due to limitations in material and structure, it cannot meet the requirements of special customers. Ordinary cast steel does not have good wear resistance and wears out very quickly when grinding harder materials; moreover, the integrated design means that when significant wear occurs at a single partition, the entire turntable needs to be replaced, resulting in high maintenance costs.

[0003] With the upgrading of industrial demands, detachable turntables have emerged through modular design, aiming to solve the problem of rapid repair after local wear and breakage, while reducing material waste. Summary of the Invention

The two first partitions are symmetrically mounted on the two spacers, passing closely through each other; The second partition is provided with a second through hole that precisely matches the size and shape of the second polygonal protrusion structure, so as to ensure that the two second polygonal protrusion structures can be tightly embedded together into the second through hole.

[0011] Preferably, the four corners of the regular quadrilateral structure are rounded. The purpose of the rounded corners is to alleviate stress concentration at the corners and improve the fatigue life and strength of the structure.

[0022] As shown in Figures 1-7, a novel detachable turntable structure includes: two spacers 1, two first partitions 5, and one second partition 6.

[0023] Specifically, each of the two spacers 1 is provided with a first polygonal protrusion structure 2 and a second polygonal protrusion structure 3. The two spacers 1 are symmetrically arranged about a horizontal line passing through their center. The two spacers 1 are made of ordinary cast steel, and each spacer 1 is provided with a spindle mounting hole 4. The spindle mounting hole 4 is provided with a keyway so that the spacer 1 can be installed on the target spindle by means of a flat key. Each of the two first partition plates 5 is provided with a first through hole that precisely matches the size and shape of the first polygonal protrusion structure to ensure that the first polygonal protrusion structure can pass through tightly. The two first partition plates 5 are symmetrically installed on the two spacers 1. The second partition plate 6 is provided with a second through hole that precisely matches the size and shape of the second polygonal protrusion structure to ensure that the two second polygonal protrusion structures can be tightly embedded in the second through hole together. It should be noted that the first Both the first partition 5 and the second partition 6 are made of wear-resistant steel plate material, which is rolled steel plate containing wear-resistant elements such as Mn and Cr. The protrusion height of the first polygonal protrusion structure 2 is twice that of the second polygonal protrusion structure 3, so that the second polygonal protrusion structures 3 on both partition sleeves 1 can be simultaneously embedded into the second through hole.

[0024] In a preferred embodiment, the first partition 5, the second partition 6, and the spacer 1 are provided with a plurality of internally threaded holes 7 evenly spaced circumferentially, so that the first partition 5, the second partition 6, and the spacer 1 can be fixedly connected together by high-strength bolts 12. The first partition 5 and the second partition 6 are provided with a plurality of pin mounting holes 8 evenly spaced circumferentially, the pin mounting holes 8 are used to install pins 9, the pins 9 are used to install grinding rollers 10, and the grinding rollers 10 are located between the first partition 5 and the second partition 6.

[0025] In a preferred embodiment, both the first polygonal protrusion structure 2 and the second polygonal protrusion structure 3 are regular quadrilateral structures 15, and the first through hole and the second through hole are also regular quadrilateral structures 15. Each of the four corners of the regular quadrilateral structure 15 is rounded 13, and the four corners of the first through hole and the second through hole are also rounded 13. The purpose of the rounded corners 13 is to alleviate stress concentration at the corners and improve the strength and fatigue life of the structure. When subjected to torque or other loads, stress concentration occurs at the right angles of the regular quadrilateral structure 15. This is because the geometry changes abruptly at the right angles, resulting in uneven stress distribution, with local stress much higher than the average stress. The rounded corners 13 can make the geometric transition smoother and the stress distribution more uniform, thereby effectively reducing the stress peak at the right angles and improving the strength and fatigue life of the structure. When subjected to pressure, the rounded corners 13 can better disperse the pressure, making the overall stress distribution of the structure more uniform. Compared to right-angle structures, rounded corners (13) can prevent premature local plastic deformation or failure, improving the structure's compressive strength under loads such as moments. During assembly and use, right-angle structures are easier to work with compared to other components or those handled by operators. Impacts and collisions can cause structural damage or personal injury. Rounding the corners (13mm) makes the edges of the structure smoother, reducing the risk of impacts and improving safety during use.

[0026] In a preferred embodiment, both the first polygonal protrusion structure 2 and the second polygonal protrusion structure 3 are regular pentagonal structures 16, and the first through hole and the second through hole are also regular pentagonal structures 16. The interior angle of the regular pentagonal structure 16 is 108°, the force distribution at the node is more balanced, the shear stress is reduced, and the torque transmission efficiency is improved.

[0027] In a preferred embodiment, both the first polygonal protrusion structure 2 and the second polygonal protrusion structure 3 are regular hexagonal structures 17, and the first through hole and the second through hole are also regular hexagonal structures 17. The interior angle of the inner hexagonal structure is 120°, the force components of the nodes are completely symmetrical, the shear stress is minimized, and the torque transmission is most stable, making it suitable for high-precision and high-reliability scenarios.

[0028] The foregoing has shown and described the basic principles, main features, and advantages of this application. Those skilled in the art should understand that this application is not limited to the above embodiments, and various changes and modifications can be made without departing from the spirit and scope of this application; all such changes and modifications fall within the scope of the claims.
