Description

Technical Field

[0001] This utility model relates to the field of titanium concentrate technology, and in particular to a vibration damping device suitable for titanium concentrate vibrating screens. Background Technology

[0002] Titanium concentrate is a high-density (typically 4.2-4.8 g / cm³), high-hardness, and sharply textured mineral raw material widely used in high-end industrial fields such as titanium dioxide and titanium alloys. Its screening process requires the use of vibrating screens to classify the ore to meet the particle size requirements of subsequent beneficiation or smelting. However, due to the special physical properties of titanium concentrate (such as high abrasiveness, easy agglomeration, and large moisture fluctuations), vibrating screens used for screening titanium concentrate generate more intense vibration energy than other vibrating screens during operation to prevent agglomeration.

[0003] Most existing vibrating screens use springs for vibration damping. However, it has been found that a single spring cannot withstand excessive loads during operation. The vibration energy of the vibrating screen is directly transmitted to the screen frame, motor base, and factory foundation, causing cracks in the support structure, loose bolts, and even resonance, which seriously threatens equipment safety and production continuity.

[0057] In the description of this utility model, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0058] Given that the current technology of vibrating screens uses springs for vibration damping, it is impossible to withstand excessive loads. The vibration energy of the vibrating screen is directly transmitted to the screen frame, motor base and factory foundation, which leads to cracking of the supporting structure of the vibrating screen, loosening of bolts, and even resonance, seriously threatening the safety of the equipment and the continuity of production.

[0059] like Figures 1-6As shown, this utility model embodiment provides a vibration damping device suitable for a titanium concentrate vibrating screen, including: multiple double vibration damping units S connected to the vibrating screen 5, each double vibration damping unit S including: a connecting block 1, a first damping spring 2, and a vibration damping seat 3, etc.

[0060] The connecting block 1 is welded to the side wall of the vibrating screen 5, and its side is flag-shaped. A first damping spring 2 is located at the bottom of the connecting block 1, extending along the axial direction of the vibrating screen 5, and there is at least one of them. The high elastic deformation capacity of the first damping spring 2 absorbs the vibration energy generated during the operation of the vibrating screen 5. A vibration damping seat 3 is located at the bottom of the first damping spring 2, extending along the axial direction of the vibrating screen 5, and is welded to the screen frame 6. The vibration damping seat 3 is configured to dissipate residual vibration energy.

[0061] Multi-stage vibration reduction is achieved through the cooperation of the first damping spring 2 and the vibration damping seat 3, thereby blocking the transmission path of vibration energy and reducing the risk of structural fatigue and resonance.

[0062] Specifically, such as Figure 3 As shown, the vibration damping seat 3 includes several parts such as an upper fixed frame 31, a vibration damping column 33, and a lower fixed frame 32.

[0063] The lower fixed frame 32 is welded to the screen frame 6. The upper fixed frame 31 is located above the lower fixed frame 32, opposite to it, and is larger than the lower fixed frame 32, meaning the bottom of the upper fixed frame 31 can cover the lower fixed frame 32. The top of the upper fixed frame 31 is connected to the first damping spring 2. A damping column 33 is located between the upper fixed frame 31 and the lower fixed frame 32, with one end detachably connected to the upper fixed frame 31 and the other end detachably connected to the lower fixed frame 32. There is at least one damping column 33. When an external impact force acts on the damping column 33, the column deforms to absorb kinetic energy, thereby dissipating residual vibration energy.

[0064] Furthermore, such as Figures 3-5As shown, the vibration damping column 33 includes: a vibration damping body 331 detachably mounted within the lower fixed frame 32; a connecting cover 332 on the top of the vibration damping body 331; multiple grooves 3321 on the connecting cover 332; a piston rod 333 inserted through the top of the connecting cover 332; a mounting plate 334 connected to the top of the piston rod 333; the mounting plate 334 detachably connected to the upper fixed frame 31; and a dust cover 335 connected to the lower end face of the mounting plate 334. The dust cover 335 is located outside the piston rod 333 and adapts to the movement of the piston rod 333 during vibration damping. The dust cover 335 effectively prevents dust, dirt, sand, and other fine particles from entering the interior of the vibration damping body 331, avoiding wear and scratches on the surface of the piston rod 333 by external particles, thereby extending the service life of the vibration damping column 33. A second damping spring 336 is provided between the connecting cover 332 and the mounting plate 334, and is sleeved on the outside of the dust cover 335.

[0065] Furthermore, in this embodiment, the dust cover 335 is configured as a flexible corrugated telescopic structure, and the inner side of the dust cover 335 is coated with a protective coating. In use, the flexible telescopic structure allows the dust cover 335 to adaptively contract as the piston rod 333 moves during the vibration damping process.

[0066] Furthermore, to facilitate maintenance of the vibration damping column 33, the vibration damping column 33 in this embodiment is a detachable structure.

[0067] Specifically, such as Figures 4-5 As shown, the piston rod 333 is connected to a connecting seat 337 at its top end. The connecting seat 337 has a threaded groove, and a connecting post 338 is threaded into the threaded groove. The connecting post 338 is connected to the mounting plate 334. That is, the mounting plate 334 is detachably connected to the piston rod 333 through the connecting post 338 and the connecting seat 337.

[0068] A connecting plate 3351 is provided at the bottom of the outer side of the dust cover 335. Multiple circumferential slots 3352 are formed on the connecting plate 3351. Multiple fixing components 339 that mate with the slots 3352 are provided on the connecting cover 332. The dust cover 335 is detachably connected to the connecting cover 332 via the fixing components 339. Similarly, when the dust cover 335 is in a detachable state, the second damping spring 336 fitted onto the outer side of the dust cover 335 is also in a detachable state.

[0069] Furthermore, such as Figure 5As shown, the fixing component 339 includes: a fixing shaft 3391, multiple fixing shafts 3391 are provided, the multiple fixing shafts 3391 are circumferentially distributed on the connecting cover 332, and each fixing shaft 3391 has a strip plate 3392 hinged to its top end. Multiple strip holes 3352 are correspondingly provided with multiple strip plates 3392, and each strip plate 3392 has a limit insertion hole 3393 at one end. A strong spring 3394 is provided in the groove 3321, located on one side of the fixing shaft 3391, its bottom end abuts against the bottom of the groove 3321, and its top end is connected to a sliding plate 3395 that is slidably connected to the groove 3321. A limit insertion post 3396 extending out of the groove 3321 is connected to the sliding plate 3395, and the limit insertion post 3396 and the limit insertion hole 3393 are interlocked.

[0070] The lower end face of the strip plate 3392 is on the same horizontal plane as the upper end face of the connecting plate 3351, so that the strip plate 3392 can prevent the connecting plate 3351 from detaching from the connecting cover 332 during assembly.

[0071] In use, first, place the dust cover 335 on the outside of the piston rod 333 and the connecting seat 337. After installation, manually rotate the strip plate 3392 to a certain position so that the strip plate 3392 aligns with the strip hole 3352. Then, press down on the connecting plate 3351. During the pressing process, the strip plate 3392 passes through the strip hole 3352 and then through the connecting plate 3351. Then, press down on the limiting pin 3396 with one hand. The limiting pin 3396 drives the sliding plate 3395 to move downward. During the movement, the strong spring 3394 is compressed. With the other hand, rotate the strip plate 3392 again so that the limiting hole 3393 on the strip plate 3392 aligns with the limiting pin 3396. At this point, the pressure applied to the limiting pin 3396 is released. Under the elastic force of the strong spring 3394, the limiting pin 3396 passes through the limiting hole 3393 and through the strip plate 3392, limiting the strip plate 3392 and thus securing the connecting plate 3351. At this point, the dust cover 335 is installed. Then, the second damping spring 336 is sleeved on the outside of the dust cover 335. Finally, the mounting plate 334 is screwed onto the connecting seat 337 through the connecting pin 338, thus completing the installation of the vibration damping column 33. When the vibration damping column 33 needs to be disassembled, the operation is reversed. The overall disassembly and assembly are very convenient, making it easy to maintain the vibration damping column 33.

[0072] Furthermore, such as Figure 6 As shown, in this embodiment, multiple double vibration damping units S are distributed in an upper and lower layer structure around the vibrating screen 5. The lower double vibration damping unit S is welded to the screen frame 6, and the vibration damping seat 3 in the upper double vibration damping unit S is fixedly connected to the connecting block 1 in the lower double vibration damping unit S.

[0073] Furthermore, such as Figure 1As shown in Figure 2, the double damping unit S in this embodiment also includes a damping rubber 4, which is disposed on the top of the upper fixed frame 31. That is to say, the first damping spring 2 is connected to the upper fixed frame 31 through the damping rubber 4.

[0074] When using it, first, install the double vibration damping unit S as follows: Figure 6 When the structure shown is installed, during the vibration of the vibrating screen 5, the first damping spring 2 deforms and absorbs most of the vibration energy generated by the vibrating screen 5. The residual vibration energy is then transmitted to the upper fixed frame 31 via the first damping spring 2, and then to the mounting plate 334 via the upper fixed frame 31. The mounting plate 334 then transmits the vibration force to the piston rod 333. The piston rod 333 is subjected to force and flows with the oil inside the damping body 331, generating frictional resistance, thereby consuming the residual vibration energy and reducing the impact of the vibrating screen 5 on the screen frame 6, the motor base, and the factory foundation.

[0075] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
