Description

Technical Field

[0001] This utility model relates to the field of mineral processing equipment technology, specifically to a multi-stage vibration mineral processing device. Background Technology

[0002] Multi-stage vibrating mineral separators are high-efficiency mineral separation equipment that achieves fine separation of minerals through a combination of multi-stage vibrating screening and gravity separation. This device typically consists of a feeding system, a vibrating screening mechanism, multi-stage separation troughs, and a collection device. During operation, the material moves along an inclined screen surface driven by a vibrating motor. Minerals of different particle sizes and densities are separated into layers under the action of vibration and gravity. Its core advantage lies in its stepped separation structure. Traditional multi-stage vibrating mineral separators use a single power source to drive the multi-stage vibrating screening structure synchronously. The lack of relative displacement between the multi-stage vibrating screening structures results in the overall mineral separator failing to meet design requirements, thus affecting the screening efficiency of the mineral separator. Utility Model Content

[0008] Preferably, the output end of the discharge pipe extends outside the main frame.

[0009] Compared with the prior art, the beneficial effects of this utility model are: it replaces the traditional multi-stage vibrating mineral processing device that uses a single power source to drive the multi-stage vibrating screening structure to vibrate synchronously, and sets vibrators on each of the multi-stage vibrating screening structures, so that the multi-stage vibrating screening structures generate relative displacement, the overall mineral processing device achieves the design requirements for screening effect, and improves the screening efficiency of the mineral processing device.

[0016] Please see Figure 1-4This utility model provides a multi-stage vibrating mineral processing device, including a main frame 1. Inside the main frame 1, from top to bottom, there are a primary screen plate 2, a secondary screen plate 3, and a tertiary screen plate 4. The upper surfaces of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 are all provided with collection covers 5. The lower surfaces of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 are all provided with discharge covers 6. The discharge covers 6 are correspondingly arranged with the collection covers 5. The lower surfaces of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 are all provided with vibrators 7. The primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 are all provided with fixed seats 8 extending outward in four directions: front, back, left, and right. The fixed seats 8 in one direction are provided with staggered discharge pipes 9. The side wall of the main frame 1 and below the fixed seats 8 are provided with fixed plates 10. A connecting spring 11 is provided between the fixed seats 8 and the fixed plates 9.

[0017] In use, a fixing plate 10 is installed on the side wall of the main frame 1, and a fixing seat 8 is installed on the outside of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4. A connecting spring 11 is installed between the fixing seat 8 and the fixing plate 10, and the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 are flexibly connected to the inside of the main frame 1 through the connecting spring 11. A vibrator 7 is installed at the lower inside of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4, respectively. The vibrator 7 drives the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 to vibrate respectively. The material to be screened is collected in the collection hood 5 at the upper end of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4. The material is screened inside the screen plate 2. After screening, the material is discharged downward through the discharge hood 6. The material to be screened and beneficiated is poured into the inside of the primary screen plate 2. After screening inside the primary screen plate 2, the material with a larger diameter is discharged to the outside through the discharge pipe 9, and the material with a smaller diameter falls into the inside of the secondary screen plate 3. After screening inside the secondary screen plate 3, the material with a slightly larger diameter is discharged to the outside through the discharge pipe 9, and the material with a slightly smaller diameter falls into the inside of the tertiary screen plate 4. After screening inside the tertiary screen plate 4, the material with a slightly larger diameter is discharged to the outside through the material pipe 9, and the material with a slightly smaller diameter falls to the outside through the lower end of the tertiary screen plate 4, so that materials of different diameters are discharged to the outside separately.

[0018] A fixing beam 12 is provided on the side wall of the main frame 1 at a position corresponding to the fixing plate 10. The lower surface of the fixing plate 10 abuts against the fixing beam 12. A through groove 13 is provided in the middle of the fixing plate 10. The lower end of the discharge hood 6 passes through the fixing plate 10 through the through groove 13. The fixing beam 12 enhances the connection strength between the fixing plate 10 and the main frame 1. The through groove 13 on the fixing plate 10 provides space for the installation of the discharge hood 6 and also provides space for the vibration operation of the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4.

The diameter of the screen holes 14 on the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4 decreases sequentially. By providing screen holes 14 with progressively smaller diameters on the primary screen plate 2, the secondary screen plate 3, and the tertiary screen plate 4, materials of different diameters can be screened and output.
