[0002] In ore processing, screening is a crucial step between crushing and beneficiation. Its purpose is to classify the ore according to particle size to meet the requirements of subsequent flotation, gravity separation, or roasting operations. Existing ore screening equipment widely adopts structures such as vibrating screens, drum screens, or probability screens. Among these, the screen mesh is a key component that directly affects screening efficiency and particle size classification accuracy.

Detailed Implementation

[0023] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0024] Reference Figure 1 and Figure 2 An embodiment of this utility model provides: an ore processing and screening device, including a frame 1, a push rod 2 slidably connected to the inner wall of the frame 1, a U-shaped block 3 fixedly connected to the outer wall of the push rod 2, a push column 4 rotatably connected to the inside of the U-shaped block 3, a sliding frame 5 slidably connected to the outer wall of the push column 4, a connecting column 6 fixedly connected to the upper surface of the sliding frame 5, a locking block 7 fixedly connected to the top of the connecting column 6, a screen plate 8 provided on the outer wall of the locking block 7, the outer wall of the screen plate 8 slidably connected to the inner wall of the frame 1, a spring 9 fixedly connected to the lower surface of the locking block 7, the bottom end of the spring 9 fixedly connected to the inner wall of the frame 1, and a vibration component provided on the lower surface of the frame 1;

[0025] Specifically, frame 1 supports push rod 2, ensuring its stable sliding. When push rod 2 is pushed, it causes U-shaped block 3 to slide, which in turn causes push column 4 to slide against the inner wall of sliding frame 5. Push column 4 then pushes sliding frame 5, which in turn causes connecting column 6 to slide. Connecting column 6 then causes locking block 7 to slide. When locking block 7 slides out of the inner wall of screen plate 8, the screen plate 8 is released from its limit, allowing it to be pulled out of the inner wall of frame 1 for quick disassembly. When installation is required, spring 9 pushes locking block 7 upward, allowing it to slide against the inner wall of screen plate 8 for quick installation. This quick disassembly of screen plate 8 allows workers to quickly disassemble and assemble it by hand, reducing downtime and improving maintenance efficiency.

[0026] Reference Figure 3The vibration assembly includes a support plate 10, the upper surface of which is fixedly connected to the lower surface of the frame 1, and a vibrator 11 is fixedly connected to the lower surface of the support plate 10.

[0027] Specifically, the support plate 10 can provide fixed support for the frame 1. When the vibrator 11 is turned on, the vibrator 11 can vibrate the support plate 10, which in turn vibrates the entire device, facilitating screening.

[0028] Reference Figure 4 A push plate 12 is slidably connected to the lower inner wall of frame 1, and a sliding column 13 is fixedly connected to the outer wall of push plate 12; a U-shaped block 14 is fixedly connected to the outer wall of sliding column 13, and a fixed column 15 is provided on the outer wall of U-shaped block 14; a spring 16 is fixedly connected to the outer wall of U-shaped block 14, and the outer wall of spring 16 is fixedly connected to the inner wall of frame 1.

[0029] Specifically, frame 1 can support push plate 12. When push plate 12 is pushed, push plate 12 can drive sliding column 13 to slide. The sliding of sliding column 13 will drive U-shaped block 14 to slide. When U-shaped block 14 leaves the outer wall of fixed column 15, the limitation on fixed column 15 can be released, allowing fixed column 15 to slide out later. When it is necessary to limit fixed column 15, the elastic force of spring 16 can push U-shaped block 14 to slide to the outer wall of fixed column 15, achieving the limiting effect. By limiting fixed column 15, frame 1 can be restricted from being directly pushed upward to disassemble, and safety can be improved to prevent fixed column 15 from accidentally sliding out due to vibration or other reasons.

[0030] Reference Figure 4 A push plate 17 is slidably connected to the upper inner wall of frame 1, and a U-shaped plate 18 is fixedly connected to the upper surface of push plate 17. The upper surface of U-shaped plate 18 is fixedly connected to the bottom end of fixed column 15, and a locking block 19 is fixedly connected to the bottom end of fixed column 15. The outer wall of locking block 19 is set on the inner wall of frame 1. A spring 20 is fixedly connected to the inner wall of U-shaped plate 18, and a limit plate 21 is fixedly connected to the bottom end of spring 20. The outer wall of limit plate 21 is fixedly connected to the inner wall of frame 1.

[0031] Specifically, frame 1 supports push plate 2 17. When push plate 2 17 is pushed, it causes U-shaped plate 18 to slide. The sliding of U-shaped plate 18 causes fixed column 15 to slide, and the sliding of fixed column 15 also causes locking block 2 19 to slide. When locking block 2 19 slides out of another frame 1, the two frames 1 can be quickly disassembled. When it is necessary to quickly fix the two frames 1, the elastic force of spring 3 20 can push U-shaped plate 18 to slide, thereby pushing fixed column 15 and locking block 2 19 to slide into the interior of another frame 1, achieving the effect of quick fixation. By quickly disassembling frame 1, the number of screen layers or the screen hole size can be flexibly increased or decreased according to different material particle size requirements, realizing free switching between secondary screening, tertiary screening, and even multi-stage screening. This allows the same equipment to be applicable to various ores or different mineral processing stages, improving adaptability and flexibility.

[0032] Working principle: When the device is needed, pushing push rod 2 causes U-shaped block 3 to slide, which in turn causes push column 4 to slide, and push column 4 to slide, which in turn causes sliding frame 5 to slide. Simultaneously, sliding frame 5 causes connecting column 6 and locking block 7 to slide. When locking block 7 slides out of the inner wall of screen plate 8, the limiting position on screen plate 8 is released, allowing screen plate 8 to be pulled out of the inner wall of frame 1 for quick disassembly. Then, pushing push plate 12 causes sliding column 13 to slide, and sliding column 13 also causes U-shaped block 14 to slide. When U-shaped block 14 slides out of the outer wall of fixed column 15, pushing push plate 12... The push plate 17 slides, driving the U-shaped plate 18 to slide. The sliding of the U-shaped plate 18 in turn drives the fixed column 15 to slide, which in turn drives the locking block 19 to slide. When the locking block 19 slides out of the inner wall of the other frame 1, the two frames 1 can be quickly disassembled. That is, this device can not only quickly disassemble the screen plate 8, allowing workers to quickly disassemble and assemble the screen plate 8 by hand, reducing downtime and improving maintenance efficiency, but also quickly disassemble the frame 1, so that the number of screen layers can be flexibly increased or decreased or the screen hole size can be changed according to different material particle size requirements. This makes the same equipment applicable to various ores or different mineral processing stages, improving adaptability and flexibility.

[0033] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
