Description

Technical Field

[0001] This utility model relates to the field of vibrating screen equipment technology, specifically to a dual-axis anti-resonance vibrating screen. Background Technology

[0002] Vibrating screens operate by utilizing the vibrations generated by vibrators. By driving the adapted screen body to vibrate, the material on the screen mesh passes through a single or multiple layers of screen mesh with uniformly distributed holes multiple times to achieve the purpose of screening. They are now gradually being widely used in industries such as metallurgy, coal, mining, and building materials.

[0003] Existing vibrating screens include single-shaft, centrally located vibrating screens where the exciter is installed at the center of gravity. While the amplitude at the center is significant, the amplitudes at the beginning and end are relatively weak, resulting in poor screening efficiency. Furthermore, the concentrated load at the center of gravity reduces the screen's lifespan. Other types are dual-shaft vibrating screens where the center of gravity is located between two exciters, with synchronized vibration achieved via a matching synchronous belt. However, in this design, omitting the synchronous belt can lead to resonance and irregular vibrations, potentially causing cracking, twisting, and deformation, further reducing the screen's lifespan. In severe cases, this can negatively impact the overall mine's operating efficiency and increase internal operating costs. Utility Model Content

The vibrating screen body is provided with a first exciter and a second exciter. Part of the bracket assembly is adapted to be installed on the ground.

Compared with the existing technology, the arrangement of the synchronous belt is eliminated, which not only avoids the resonance problem, but also allows for arbitrary adjustment of the amplitude of each section of the screen surface to adapt to the working conditions of materials of different sizes, improves screening efficiency, and helps to extend the service life of the equipment.

[0023] This embodiment is basically as shown in the appendix. Figure 1 - Appendix Figure 5 As shown: A dual-axis anti-resonance vibrating screen includes a vibrating screen body 100 and a bracket assembly 200. A first exciter and a second exciter are arranged laterally on the vibrating screen body 100. Part of the bracket assembly 200 is adapted to be installed on the ground. A shock-absorbing component 300 is provided between the first exciter and the second exciter and the bracket assembly 200.

[0024] In specific application scenarios, two sets of matching drive components (not shown in the figure) are provided on one side of the vibrating screen body 100. Preferably, the drive component is a matching motor. The drive component is connected to the corresponding first exciter and second exciter through a matching transmission device, thereby driving the first exciter and the second exciter to run respectively. The structure, principle and other corresponding structural technical solutions of the first exciter, second exciter, drive component and transmission device have been described in detail in the prior art. That is, the structure of the first exciter, second exciter, drive component and transmission device has become part of the prior art, and will not be described in detail here.

[0025] By employing a technical solution that incorporates damping components 300 between the first and second vibrators and the bracket assembly 200, the first vibrator and the damping components 300 are adapted to form a separate structure, and the second vibrator and the damping components 300 are adapted to form a separate structure. Compared to existing technologies, this eliminates the need for a synchronous belt, which not only avoids resonance issues but also allows for arbitrary adjustment of the amplitude of each section of the screen surface to adapt to the working conditions of materials of different sizes, thereby improving screening efficiency and helping to extend the service life of the equipment.

[0026] Compared to existing technologies, the reduced synchronous belt arrangement and elimination of the need for matching reinforcing steel result in a relatively high overall integration of the equipment. Furthermore, the wheelbase between the first and second vibrators can be increased to over 4.5m, and the rotation speed of the first and second vibrators can be increased to 970 rpm. The overall weight of the equipment can be reduced from 30 tons in existing technologies to approximately 18 tons, which helps to reduce structural costs and achieve some energy conservation and emission reduction goals.

[0027] When it is necessary to change the amplitude of the first or second exciter, the amplitude can be adjusted by adding or removing appropriate counterweights. In this embodiment, the default amplitude of the first and second exciters is 6mm.

[0028] To facilitate the reasonable arrangement of the first and second vibrators, in this embodiment, the vibrating screen body 100 is provided with a protective member 110, which is used to protect the ends of the first and second vibrators; the vibrating screen body 100 is provided with a connecting member 120, and the protective member 110 is provided on the connecting member 120.

[0029] Specifically, the connector 120 is fixedly assembled to the side wall of the vibrating screen body 100 by means of appropriate bolts, and the protective part 110 is fixedly assembled to the connector 120 by means of appropriate bolts.

[0030] Furthermore, the shock absorption assembly 300 includes a shock absorption tube 310 and a buffer member 320; the shock absorption tube 310 is adapted to be installed on the vibrating screen body 100, and a support member 330 is connected between the shock absorption tube 310 and the connector 120; the buffer member 320 is located between the shock absorption tube 310 and part of the structure of the bracket assembly 200.

[0031] Specifically, the damping tube 310 is arranged laterally through the vibrating screen body 100, and the end of the damping tube 310 extends out of the vibrating screen body 100. The connecting member 120 has folded edges 121 on both sides. The support member 330 has a transverse section 331, and both ends of the transverse section 331 are connected to longitudinal sections 332. The ends of the two longitudinal sections 332 are fixedly assembled to the corresponding folded edges 121 using matching bolts. The end of the damping tube 310 and the transverse section 331 are fitted and fixedly assembled using matching bolts.

[0032] The bracket assembly 200 includes a base support 210 and a buffer 320 adapted to clamp or press between the circumferential sidewall of the shock absorber tube 310 and the base support 210. In this embodiment, the base support 210 is preferably an I-beam. In specific usage scenarios, the base support 210 is adapted to be placed on the ground to achieve its basic support function.

[0033] The vibrating screen body 100 is arranged at an inclination, with the preferred inclination angle being 18-20°. An extension member 220 is provided between the buffer member 320 and the bottom support member 210 in the damping component 300 located below the first vibrator. Based on the inclination arrangement of the vibrating screen body 100, the distance between the damping component 300 and the bottom support member 210 below the first vibrator is relatively increased. By arranging the extension member 220, it is convenient to realize the adaptive height adjustment installation between the damping component 300 and the bottom support member 210.

[0034] To facilitate the reasonable arrangement of the buffer 320 and to ensure a relatively compact and stable structure, in this embodiment, the buffer 320 includes a top plate 321, a bottom plate 322, and a buffer body 323, with the buffer body 323 located between the top plate 321 and the bottom plate 322.
