Description

Technical Field

[0001] This utility model relates to the field of screen cleaning technology, and to a self-cleaning vibrating screen device for ore sorting machines. Background Technology

[0002] Ore sorting is a key step in the mining production process. It effectively separates valuable minerals from gangue, thereby improving the grade of the ore and providing high-quality raw materials for subsequent smelting and other processing steps. Its working principle is usually that a vibrating motor provides power to make the screen body and screen mesh form an elastic vibration system. The material is thrown on the screen mesh. The material smaller than the screen mesh size passes through the screen mesh and becomes the undersize product, while the material larger than the screen mesh size remains on the screen mesh and becomes the oversize product, thereby realizing the screening and separation of materials.

[0003] During the ore sorting process, the ore often contains a large amount of dust and small ore particles. These impurities are very easy to adhere to the screen holes and surface of the screen, and the screen holes are gradually blocked, resulting in a significant decrease in the screen penetration rate, a reduction in the effective sorting area, and a significant decrease in sorting efficiency. At present, the cleaning of vibrating screens is mainly done manually. Manual cleaning is labor-intensive and inefficient, increases labor costs and equipment downtime, and affects the continuity and stability of production.

[0004] To address the aforementioned issues, this application proposes a self-cleaning vibrating screen device for ore sorting machines. Utility Model Content

[0034] Reference Figures 1 to 6 A self-cleaning vibrating screen device for an ore sorting machine includes: a sorting machine body 2; a sorting screen 5 installed inside the sorting machine body 2; an outer support frame 1 fixedly connected to the outer side of the sorting machine body 2; a linear module 10 symmetrically installed on the top of the outer support frame 1, with a side support plate 9 installed on the moving slide of the linear module 10; an inner support plate 11 fixedly connected to the inner side of the side support plate 9; a second cylinder 24 symmetrically installed on the top of the inner support plate 11 by bolts, with an adjusting support plate 12 fixedly connected to the output end of the second cylinder 24; a sliding ventilation box 16 slidably disposed at the bottom of the adjusting support plate 12, with multiple airflow nozzles 20 equidistantly arranged at the bottom of the sliding ventilation box 16; and a bottom fixed support plate 19 symmetrically installed at the bottom of the adjusting support plate 12 by bolts, with a cleaning roller 21 rotatably disposed on the inner side of the bottom fixed support plate 19.

[0035] Reference Figure 3 and Figure 4 An inner sliding block 13 is fixedly connected to the top of the sliding ventilation box 16. The inner sliding block 13 is slidably connected to the adjusting support plate 12. A limit slide rod 14 is symmetrically slidably arranged inside the inner sliding block 13. The limit slide rod 14 is fixedly connected to the adjusting support plate 12. A first cylinder 15 is installed inside the adjusting support plate 12. The output end of the first cylinder 15 is fixedly connected to the inner sliding block 13.

[0036] The output end of cylinder 15 drives the inner sliding block 13 to slide within the adjusting support plate 12. The inner sliding block 13 drives the sliding ventilation box 16 and each airflow nozzle 20 to move. The airflow nozzles 20 blow air to remove impurities from the sorting screen 5, thus completing the cleaning work.

[0037] Reference Figures 1 to 5 An air inlet box 17 is fixedly connected to one side of the sliding ventilation box 16. The air inlet box 17 is slidably connected to the adjusting support plate 12. A high-pressure air pipe 18 is provided on one side of the air inlet box 17. A motor 22 is installed on one side of one of the bottom fixed support plates 19 by bolts. The output end of the motor 22 is fixedly connected to the cleaning roller 21.

[0038] The cleaning roller 21 is driven to rotate by the output end of the motor 22. The cleaning roller 21 cleans the impurities on the sorting screen 5 and thoroughly cleans the sorting screen 5.

[0039] Reference Figure 2 and Figure 4 Multiple limiting rods 23 are symmetrically fixed to the top of the adjusting support plate 12, and the limiting rods 23 are slidably connected to the inner support plate 11.

[0040] The output end of cylinder 24 drives the adjusting support plate 12 to adjust its height. The adjusting support plate 12 drives multiple limit rods 23 at the top to move synchronously. The limit rods 23 slide against the inner support plate 11, thereby improving the stability of the vertical adjustment of the adjusting support plate 12.

[0041] Reference Figures 1 to 6 A guide seat 7 is fixedly connected to the inner side of the outer support frame 1, and a guide plate 8 is symmetrically fixedly connected to the top of the guide seat 7. A limit cylinder 25 is symmetrically installed on one side of the outer support frame 1, and a limit side groove 26 that cooperates with the output shaft of the limit cylinder 25 is symmetrically opened on one side of the sorting machine body 2.

[0042] By cooperating with the output shaft of the limiting cylinder 25 and the limiting side groove 26, the output shaft of the limiting cylinder 25 enters the limiting side groove 26, stabilizing the position of the sorting machine body 2 and the sorting screen 5, which facilitates cleaning.

[0043] Reference Figure 1 , Figure 2 , Figure 5 and Figure 6 The bottom of the sorting machine body 2 is fixedly connected to a first discharge pipe 3, and the bottom of the sorting machine body 2 is fixedly connected to a second discharge pipe 4 that cooperates with the sorting screen 5. The top of the sorting machine body 2 is provided with a movable top groove 6.

[0044] The ore on the sorting screen 5 is discharged through the second discharge pipe 4, and the ore below the sorting screen 5 is discharged through the first discharge pipe 3.

[0045] Working principle:

[0046] The sorting machine body 2 is powered by a vibrating motor. Supported by springs, the screen body and sorting screen 5 form an elastic vibration system, achieving material screening. After the vibrating motor starts, it drives the sorting machine body 2 and the sorting screen 5 to vibrate. The material is screened on the sorting screen 5. Coarse ore is discharged through the second discharge pipe 4, and the screened fine ore is guided and discharged through the first discharge pipe 3. The movable top trough 6 prevents the sorting machine body 2 from touching the inner support plate 11 and the side support plate 9, thus avoiding interference with normal screening operations. Material base 7 and guide plate 8 guide the ore onto sorting screen 5 for screening. After screening, when cleaning of sorting screen 5 is required, the spring and sorting machine body 2 stabilize, and the output shaft of limit cylinder 25 moves into limit side groove 26. The output end of limit cylinder 25 limits the range of motion of sorting machine body 2 through limit side groove 26 to avoid excessive shaking during cleaning, which would affect the cleaning effect. The linear module 10 moves smoothly. The platform moves the side support plate 9 and the inner support plate 11. The inner support plate 11 drives the second cylinder 24, the adjusting support plate 12, the sliding ventilation box 16, the bottom fixed support plate 19, and the cleaning roller 21 to move. One end of the high-pressure air pipe 18 is connected to a blower. The blower blows air into the air inlet box 17 and the sliding ventilation box 16 through the high-pressure air pipe 18. The air is blown through multiple air nozzles 20 at the bottom of the sliding ventilation box 16, removing impurities from the sorting screen 5. The second cylinder 24 then blows the air through these nozzles. The output end of the motor 22 drives the adjusting support plate 12, the sliding ventilation box 16, the bottom fixed support plate 19 and the cleaning roller 21 to move downward. The output end of the motor 22 drives the cleaning roller 21 to rotate. The cleaning roller 21 cleans the sorting screen 5. High-pressure airflow is sprayed onto the sorting screen 5 through the sliding ventilation box 16 and the airflow nozzle 20 to blow away the attached substances such as dust and small ore particles inside and on the screen holes. The cleaning roller 21 rotates under the drive of the motor 22 to physically scrub the sorting screen 5.
