Description

Technical Field

[0001] This utility model relates to the field of high-frequency screen technology, specifically a high-frequency screen that is easy to assemble and disassemble quickly. Background Technology

[0002] High-frequency screens utilize high frequencies to disrupt the surface tension of the slurry and cause high-speed oscillation of fine materials on the screen surface. This accelerates the separation of denser useful minerals and increases the probability of materials smaller than the separation particle size coming into contact with the screen openings, resulting in better separation conditions. High-frequency screens are characterized by high efficiency, small amplitude, and high screening frequency, making them an effective device for screening and classifying fine materials. They are widely used in screening or classifying operations in beneficiation plants for iron ore, tin, tungsten, tantalum, niobium sand, and other minerals.

[0003] Screen replacement is the most critical and common maintenance task when using a high-frequency screen. Improper operation can seriously affect screening efficiency and product quality, and lead to premature screen damage. Furthermore, different materials require different screen surfaces, and due to the large screen area, replacing a single screen is labor-intensive and troublesome. Therefore, we have proposed a high-frequency screen that is easy to assemble and disassemble to address these issues. Utility Model Content

Specifically, such as Figure 1 and Figure 2 As shown, by setting up a quick-assembly and disassembly structure, during use, the sieve 14 is inserted into the side sliding grooves 12 on both sides inside the screen frame 1. The sieve 14, carrying the inner limiting seat 13, slides inside the side sliding grooves 12 to lay the sieve 14 inside the screen frame 1. The inner limiting seat 13 on the top right side of the sieve 14 contacts the right side inside the screen frame 1. Then, the first locking knob 15 is inserted into the inner limiting seat 13 and the left side of the sieve 14 respectively, so that the first locking knob 15 passes through the inner limiting seat 13 and the sieve 14 and contacts and fixes with the screen frame 1, thereby realizing the quick-assembly and disassembly function.

[0018] The screen frame 1 has upper connecting seats 2 on both the front and rear ends. The bottom of the upper connecting seats 2 is connected to a vibration spring 4. The bottom of the vibration spring 4 is connected to a support seat 7. The bottom of the support seat 7 is installed with a lower fixed frame 8. The screen frame 1 has diagonal bracing rods 3 on both the front and rear ends. The lower fixed frame 8 has an anti-collision seat 19 installed on the left side inside. The lower fixed frame 8 has an auxiliary wheel column 18 inside. The top of the auxiliary wheel column 18 is installed with a collection box 6. The right side of the collection box 6 is connected with a side handle 17. The side handle 17 is located on the right side of the collection box 6. The collection box 6 is placed inside the top of the lower fixed frame 8. The collection box 6 contacts the auxiliary wheel column 18 inside the lower fixed frame 8. The collection box 6 slides on the top of the lower fixed frame 8 through the auxiliary wheel column 18 and contacts the anti-collision seat 19 on the left side of the lower fixed frame 8. Specifically, such as Figure 1 and Figure 3As shown, by setting up a material receiving and moving structure, the collection box 6 at the top of the lower fixed frame 8 receives the material screened inside the screen frame 1. Then, the collection box 6 is moved on the top of the lower fixed frame 8 by the side handle 17. The collection box 6 moves inside the lower fixed frame 8 through the auxiliary wheel column 18 inside the lower fixed frame 8, which facilitates the movement and adjustment of the collection box 6 and the movement of the material inside the collection box 6, thereby realizing the material receiving and moving function.

[0019] A rotating shaft 11 is provided on the right side inside the screen frame 1. The bottom of the rotating shaft 11 is connected to a lower movable seat 22. The bottom of the lower movable seat 22 is connected to a telescopic seat 23. A second locking knob 24 is provided on the right side of the lower movable seat 22. A spring 20 is connected to the left side of the lower movable seat 22. Spring connecting seats 21 are provided at the front and rear inside the screen frame 1. The lower movable seat 22 rotates on the right side of the screen frame 1 via the rotating shaft 11. The telescopic seat 23 extends and retracts at the bottom of the lower movable seat 22. The second locking knob 24 is inserted into the lower movable seat 22 and contacts the telescopic seat 23 inside the lower movable seat 22. Two sets of spring connecting seats 21 and return springs 20 are provided. The spring connecting seat 21 is connected to the lower movable seat 22 through the return springs 20. Specifically, such as Figure 2 and Figure 4 As shown, by setting a side feeding adjustment structure, during use, the telescopic seat 23 at the bottom of the lower movable seat 22 is extended or retracted to adjust the distance between the telescopic seat 23 at the bottom of the lower movable seat 22 and the screen 14. Then, the telescopic seat 23 at the bottom of the lower movable seat 22 is fixed by locking knob 24. When the material at the top of the screen 14 moves downward, it will contact the telescopic seat 23. The telescopic seat 23 rebounds through the spring 20 and the spring connecting seat 21, so that the lower movable seat 22 and the telescopic seat 23 limit the material. After the material at the top of the screen 14 is spread flat, it is discharged from the right side of the screen frame 1, thus realizing the side feeding adjustment function.

[0020] Working principle: In this invention, the sieve 14 is inserted into the side sliding grooves 12 on both sides of the screen frame 1. The sieve 14, carrying the inner limiting seat 13, slides within the side sliding grooves 12, laying the sieve 14 inside the screen frame 1. The inner limiting seat 13 on the top right side of the sieve 14 contacts the right side of the screen frame 1. Then, the first locking knob 15 is inserted into the inner limiting seat 13 and the left side of the sieve 14, respectively, so that the first locking knob... 15. Passing through the inner limit seat 13 and the screen 14, the screen is fixed in contact with the screen frame 1. Then, the telescopic seat 23 at the bottom of the lower movable seat 22 is extended or retracted to adjust the distance between the telescopic seat 23 at the bottom of the lower movable seat 22 and the screen 14. Then, the telescopic seat 23 at the bottom of the lower movable seat 22 is fixed by the second locking knob 24. By starting the high-frequency motor 5 at the top of the inner mounting bracket 10 at the top of the screen frame 1, the high-frequency motor 5 reaches the screen frame 1 through the screen. Vibrating spring 4 vibrates at the bottom of support base 7, allowing material to be placed on top of screen 14 inside screen frame 1. After screening, the material is conveyed through the lower discharge port 16 at the bottom of screen frame 1 to the collection box 6 at the top of lower fixed frame 8. When the material on top of screen 14 moves downward, it contacts telescopic seat 23. Telescopic seat 23 rebounds through spring spring 20 and spring connecting seat 21, allowing lower movable seat 22 and telescopic seat 23 to limit the material. After the material on top of screen 14 is spread out, it is discharged from the right side of screen frame 1. Finally, collection box 6 at the top of lower fixed frame 8 receives the material screened inside screen frame 1. Then, the collection box 6 is moved on top of lower fixed frame 8 by side handle 17. The collection box 6 moves inside lower fixed frame 8 via auxiliary wheel column 18, which facilitates the movement and adjustment of collection box 6 and the movement of material inside collection box 6.
