Description

Technical Field

[0001] The utility model belongs to the field of vibrating screens, especially a large vibrating screen based on double vibrators. Background Art

[0002] As an important device widely used in the screening of solid granular materials, the main function of a vibrating screen is to separate and classify the particles in a mixture according to certain specifications, and its performance directly affects the screening efficiency and quality of the materials. There are many challenges in the large-scale and high-efficiency aspects of traditional vibrating screen equipment. In some special demand occasions, because most of the existing vibrating screen equipment uses a single vibrator, its screening efficiency and quality are limited by the performance of the vibrator and cannot meet the requirements. In addition, during the vibration process of a large vibrating screen, due to the large size and heavy mass of the equipment, it is difficult for the vibration energy generated by the vibrator to be evenly distributed, resulting in poor screening effects. Content of the Utility Model

[0003] Aiming at the deficiencies existing in the prior art, the utility model designs a new type of large feeding vibrating screen based on double vibrators. By configuring two vibrators for the vibrating screen, the screening efficiency and quality are improved to meet the material screening requirements in some special occasions.

[0004] A new type of large feeding vibrating screen based on double vibrators mainly includes a vibrating table, a screen mesh, a support seat, vibrators, a main vibration isolation device, bolts and a buffer layer. It is characterized in that the number of the vibrating table and the vibrators is two groups; the vibrators are installed on the vibrating table; the screen mesh is fixedly connected to the vibrating table at the bottom with bolts; the screen mesh is composed of a mesh surface and a screen trough; the bolts pass through the screen trough and the vibrating table in sequence on the left side, and pass through the screen trough, the buffer layer and the vibrating table in sequence on the right side; the function of the screen trough is to gather large particle materials and reduce the loss of the screen mesh.

[0005] Further, the structure of the vibrating table includes a conveying hopper, a support and a convex platform; the structure of the support seat includes a support seat base, a support rod A and a support rod B.

[0006] Further, the support is connected to the support rod A through the main vibration isolation device; the vibrating table is connected to the support rod B through a secondary vibration isolation device.

[0007] Further, the two groups of vibrating tables are fixedly connected with bolts; the bolts pass through the convex platform, the buffer layer and the convex platform in sequence.

[0008] Further, the structure of the buffer layer includes a rubber roll and a spring. Description of the Drawings

Specific implementation mode

[0013] The present utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0014] As Figure 1 、 2 、and shown in Fig. 3, a new type of large feed vibrating screen based on double vibrators mainly includes a vibrating table 1, a screen mesh 2, a support seat 3, a vibrator 4, a main vibration isolation device 5, a bolt 6 and a buffer layer 7. The number of the vibrating table 1 and the vibrator 4 is two groups. The vibrator 4 is installed on the vibrating table 1. The screen mesh 2 and the vibrating table 1 are fixedly connected by bolts 6 at the bottom position. The screen mesh 2 is composed of a mesh surface 201 and a screen trough 202. The bolt 6 passes through the screen trough 202 and the vibrating table 1 in sequence on the left side, and passes through the screen trough 202, the buffer layer 7 and the vibrating table 1 in sequence on the right side. The structure of the vibrating table 1 includes a conveying hopper, a support 101 and a boss 102. The structure of the support seat 3 includes a support seat base, a support rod A 301 and a support rod B 302. The support 101 and the support rod A 301 are connected by the main vibration isolation device 5. The vibrating table 1 and the support rod B 302 are connected by the secondary vibration isolation device 5a. The two groups of vibrating tables 1 are fixedly connected by bolts 6. The bolt 6 passes through the boss 102, the buffer layer 7 and the boss 102 in sequence. The structure of the buffer layer 7 includes a rubber roll and a spring.

[0015] When the vibrating screen starts to work, the conveyed material enters the screen mesh 2, and the two groups of vibrators 4 start to work, so that the fed material will pass through the mesh surface 201 of the screen mesh 2 according to the particle size. The material passing through the screen mesh 2 enters the vibrating table 1, and the material that does not pass through the screen mesh 2 falls onto the screen trough 202, thereby realizing the separation and classification of coarse and fine materials.

[0016] The above are only the preferred embodiments of the present utility model, and thus do not limit the protection scope of the present utility model. For those skilled in the art, various modifications and variations can be made to the present utility model. Any changes, modifications, substitutions, integrations, and parameter changes made to these embodiments by means of conventional substitutions or capable of achieving the same functions without departing from the principle and spirit of the present utility model fall within the protection scope of the present utility model.
