Description

Technical Field

[0001] This utility model is a composite tailings screen, belonging to the field of screening equipment technology. Background Technology

[0002] Tailings are solid waste remaining after ore beneficiation, containing a large number of useful components that need to be recycled. Tailings screens are commonly used equipment in tailings treatment to separate the useful components from the waste rock. Traditional tailings screens typically use a single-layer screen structure. Traditional single-screening equipment has certain limitations in terms of processing capacity, separation accuracy, and adaptability, making it difficult to meet the high standards of modern industrial production. To overcome these problems, composite tailings screens have emerged.

[0003] However, traditional composite tailings screens use multiple power sources for multi-level control and screening, which is energy-intensive and the screening effect needs to be improved. There is an urgent need for a composite tailings screen to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this invention is to provide a composite tailings screen to solve the problems mentioned in the background. This invention uses a drive motor to control the drum screen, and can also vibrate the upper corrugated screen plate and the lower strip screen plate to ensure better screening effect of tailings materials in the subsequent process, thus achieving low-energy consumption and high-efficiency tailings screening operation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: A composite tailings screen includes a bottom support plate, a drum screen, an upper corrugated screen plate, and a lower strip screen plate. Vertical plates are longitudinally fixed to the left and right sides of the upper end of the bottom support plate. A drive motor is installed on the upper left side of the left vertical plate. A connecting shaft is installed between the two vertical plates. The drum screen is fixed between the two connecting shafts. A drive wheel is installed on the outside of each of the two connecting shafts. Multiple return springs are longitudinally arranged on the upper end of the bottom support plate, and horizontally arranged at the upper ends of the multiple return springs. The screening box has an upper corrugated screen plate horizontally fixed at its upper end, and the surface of the upper corrugated screen plate has multiple circular screen holes. A lower strip screen plate is horizontally installed at the lower end of the screening box. A striking block is welded to the upper side of both the left and right ends of the screening box. A bearing seat is embedded and fixed in the middle of the side surface of the two vertical plates. A rotating shaft is installed in each of the two bearing seats. A swing block is fixed to the inner side of each of the two rotating shafts. A driven wheel is fixed to the annular side of each of the two rotating shafts. The two driven wheels are synchronously connected to the two driving wheels through a synchronous belt.

[0006] Furthermore, an addition port is provided through the upper right side of the drum screen.

[0007] Furthermore, the drum screen is located above the upper corrugated screen plate.

[0008] Furthermore, the drive motor shaft is connected to the left connecting shaft via a transmission connection, and the drive motor is connected to an external power source via a wire.

[0009] Furthermore, the screening box has multiple discharge slots at its front end.

[0010] Furthermore, the lower ends of the two swing blocks respectively abut against the two striking blocks.

[0011] The beneficial effects of this utility model are as follows: This utility model is a composite tailings screen. Because it adds a drive motor, connecting shaft, drum screen, drive wheel, synchronous belt, driven wheel, rotating shaft, swing block, striking block, screening box, upper corrugated screen plate, return spring and lower strip screen plate, our design improvement and actual use show that this device has a reasonable structure and good practicality.

Detailed Implementation

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0018] Please see Figures 1-3 This utility model provides a technical solution: a composite tailings screen, including a bottom support plate 1, a drum screen 5, an upper corrugated screen plate 16, and a lower strip screen plate 19. Vertical plates 2 are longitudinally fixed to the left and right sides of the upper end of the bottom support plate 1. A drive motor 3 is installed on the upper left side of the left vertical plate 2. A connecting shaft 4 is installed between the two vertical plates 2. The drum screen 5 is fixed between the two connecting shafts 4. Drive wheels 7 are installed on the outside of both connecting shafts 4. Multiple return springs 18 are longitudinally arranged on the upper end of the bottom support plate 1. A screening box 14 is horizontally arranged above the multiple return springs 18. The upper corrugated screen plate 16 is horizontally fixed inside the screening box 14. The corrugated screen plate 16 has multiple circular screen holes 17 on its surface. The lower strip screen plate 19 is horizontally installed at the lower end of the screening box 14. The upper sides of the left and right ends of the screening box 14 are welded with striking blocks 13. The middle of the side surfaces of the two vertical plates 2 are embedded with bearing seats 10. The two bearing seats 10 are installed with rotating shafts 11. The inner sides of the two rotating shafts 11 are fixed with swing blocks 12. The annular sides of the two rotating shafts 11 are fixed with driven wheels 9. The two driven wheels 9 are synchronously connected to the two driving wheels 7 through synchronous belts 8. This design solves the problem that the traditional composite tailings screen uses multiple power sources for multiple control screening, which is more energy-consuming and the screening effect needs to be improved.

[0019] In the first embodiment of this utility model: an addition port 6 is provided through the upper right side of the drum screen 5, facilitating the addition of tailings material into the drum screen 5. The drum screen 5 is located above the upper corrugated screen plate 16. As the drum screen 5 rotates, the screened tailings material is discharged to the upper corrugated screen plate 16. The shaft of the drive motor 3 is connected to the left connecting shaft 4 for transmission. The drive motor 3 is connected to an external power source through a wire, and the added drive motor 3 can drive the drum screen 5 to rotate through the connecting shaft 4.

[0020] The screening box 14 has multiple discharge slots 15 at its front end. These slots facilitate the screening and discharge of tailings material from the screening box 14 through the upper corrugated screen plate 16 and the lower strip screen plate 19. The lower ends of two swing blocks 12 abut against two striking blocks 13. When the two swing blocks 12 rotate, they strike the two striking blocks 13, causing the screening box 14 to vibrate. This ensures the screening effect of the upper corrugated screen plate 16 and the lower strip screen plate 19. The upper corrugated screen plate 16 increases the contact area between the material and the screen, improving screening efficiency; the lower strip screen plate 19 prevents fine particles from clogging the screen holes, further enhancing screening efficiency.

[0021] As a second embodiment of this utility model: the tailings material is added into the drum screen 5 through the adding pipe 6. When the drive motor 3 is started, the drum screen 5 will rotate through the two connecting shafts 4, thereby driving the tailings material in the drum screen 5 to be screened. At the same time, the two connecting shafts 4 will also drive the two drive wheels 7 to rotate. The rotation of the two drive wheels 7 will drive the two driven wheels 9 to rotate synchronously through the two synchronous belts 8. The synchronous rotation of the two driven wheels 9 will drive the two swing blocks 12 to rotate and strike the striking blocks 13. The two striking blocks 13 will transmit the striking vibration force to the screening box 14, causing the screening box 14 to vibrate on multiple return springs 18. The tailings material that falls into the screening box 14 through the drum screen 5 will be vibrated and screened by the upper corrugated screen plate 16. The tailings material that passes through the upper corrugated screen plate 16 will be vibrated and screened again by the lower strip screen plate 19.
