Description

Technical Field

[0001] This utility model specifically relates to a novel ore vibrating screen, belonging to the technical field of ore vibrating screens. Background Technology

[0002] A vibrating screen for ore is a mechanical device used in the mining industry for screening and grading ores. It typically uses a vibrating motor as the excitation source. When the vibrator is running, the centrifugal force generated by the eccentric block causes the screen box to vibrate at high frequency. The material continuously bounces and rolls on the inclined screen surface in an approximately circular or straight line. Material smaller than the screen aperture passes through the screen, while material larger than the screen aperture continues to move on the screen surface, thus completing the screening process.

[0003] For example, announcement number CN223159584U describes a new type of ore vibrating screen, relating to the technical field of ore screening equipment. It includes a housing with a feed hopper mounted on it and a discharge hopper on its side. A screen plate assembly is installed inside the housing, with one end of the screen plate assembly near the discharge hopper hinged to the inner wall of the housing. A connecting shaft is mounted on the side wall of the screen plate assembly away from the discharge hopper. A first base plate is mounted on the side of the housing, and a height adjustment component is mounted on the first base plate. The top of the height adjustment component is hinged to the connecting shaft. The height adjustment component allows for flexible adjustment of the screen plate assembly's inclination, enabling more reasonable control of the material flow rate during screening. It also allows for adjusting the inclination of the screen plate assembly according to different material volumes to meet the needs of tilted screening operations with varying processing capacities.

[0004] During the screening process, traditional ore vibrating screens are prone to clogging due to the adhesion and jamming of ore. Existing cleaning methods mostly use fixed-position high-pressure airflow nozzles or manual cleaning, which have the following shortcomings: First, the cleaning range of fixed nozzles is limited, making it difficult to cover the entire screen surface and easily creating cleaning blind spots. Second, the fixed distance between the nozzle and the screen cannot adapt to screens with different wear levels or ore with different particle sizes, which may lead to excessive impact damage to the screen or insufficient cleaning force.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figures 1-4 As shown, a new type of ore vibrating screen includes an ore vibrating screen body 1, a mounting plate 2, a sliding screw 3, a guide rod 4, a sliding plate 5, a PLC control panel 6, and a cleaning assembly 7. The ore vibrating screen body 1 is an existing device, mainly composed of a vibrating motor, a screen box, spring supports, and vibration dampers. The vibrating motor is the key component that drives the screen box to vibrate. The screen box is used to hold materials and perform screening. The spring supports and vibration dampers are used to reduce the impact of vibration on the equipment itself and the surrounding environment.

[0017] Mounting plate 2 is fixedly installed at both ends of the ore vibrating screen body 1. One end of mounting plate 2 is provided with a sliding groove 8. When mounting plate 2 is installed, a high-damping rubber shock-absorbing pad is added and fixed by through bolts to prevent the vibration of the ore vibrating screen body 1 during operation from affecting the sliding stability of sliding plate 5 and causing deviation in the fit between sliding plate 5 and sliding screw 3 and guide rod 4.

[0018] The sliding screw 3 is rotatably installed in the sliding groove 8, and the guide rod 4 is fixedly installed in the sliding groove 8 on the other side; One end of the sliding plate 5 is connected to the sliding screw 3, and the other end of the sliding plate 5 is sleeved on the outside of the guide rod 4. The sliding plate 5 is connected to the nut of the sliding screw 3. The sliding screw 3 and the guide rod 4 can be protected by adding a telescopic dust cover to the outside of the sliding groove 8.

[0019] The PLC control panel 6 is fixedly installed at one end of the ore vibrating screen body 1. A servo motor 10 is installed inside one end of the mounting plate 2. The output end of the servo motor 10 is fixedly connected to the sliding screw 3. The servo motor 10 is electrically connected to the PLC control panel 6. The PLC control panel 6 can control the forward and reverse rotation of the sliding screw 3. A mounting cavity is opened inside one end of the mounting plate 2. The servo motor 10 is installed in the mounting cavity by bolts.

[0020] The lower end of the mounting plate 2 is threadedly connected to a threaded rod 11. One end of the threaded rod 11 is rotatably connected to the U-shaped plate 701. A handwheel 12 is fixedly installed on one end of the threaded rod 11. The other end of the threaded rod 11 is connected to the U-shaped plate 701 through a plane bearing.

[0021] The cleaning component 7 includes a U-shaped plate 701, which is inserted into one end of the sliding plate 5. Square holes are provided on both sides of one end of the sliding plate 5. The two ends of the U-shaped plate 701 are slidably installed in the square holes. A square cavity 702 is provided inside one end of the U-shaped plate 701. Nozzles 703 are installed in a linear array on the upper end of U-shaped plate 701, and one end of nozzles 703 is connected to square cavity 702; A high-pressure air compressor 704 is fixedly installed at one end of the ore vibrating screen body 1. An air storage tank 705 is located on one side of the high-pressure air compressor 704, and the air storage tank 705 is connected to the high-pressure air compressor 704 via a pipeline. A high-pressure hose 706 is fixedly installed at one end of the air storage tank 705, and an air delivery pipe 9 is fixedly installed at one end of the high-pressure hose 706. One end of the air delivery pipe 9 passes through the mounting plate 2 and connects to the square cavity 702. The high-pressure air compressor 704 is electrically connected to the PLC control panel 6. A solenoid control valve is installed at one end of the high-pressure hose 706, and the solenoid control valve is electrically connected to the PLC control panel 6. During use, the high-pressure hose 706 has a certain length reserved for easy movement. The movement is first manually controlled via the PLC control panel. 6. Start the servo motor 10, which drives the sliding screw 3 to rotate, causing the sliding plate 5 to move back and forth. Then, start the high-pressure air compressor 704. The generated high-pressure gas is transported to the air storage tank 705 through the pipeline, and then transported to the square cavity 702 inside one end of the U-shaped plate 701 through the high-pressure hose 706 and the air delivery pipe 9. Finally, the nozzle 703 on the U-shaped plate 701 cleans the mesh of the screen, achieving full coverage cleaning of the entire screen surface. This avoids the blind spots of traditional fixed nozzles 703 and significantly reduces the screen clogging rate. The PLC control panel 6 controls the movement of the sliding screw 3 and the injection of high-pressure airflow without manual intervention, reducing downtime for cleaning, improving the continuous operation capability of the equipment, and reducing the intensity of manual labor.

[0022] Working principle: First, the ore is screened by the ore vibrating screen body 1. When it is necessary to clean the screen of the ore vibrating screen body 1, the cleaning component 7 is manually started through the PLC control panel 6 to perform full-coverage cleaning of the entire screen surface, avoiding the blind spots of traditional fixed nozzles 703 and significantly reducing the screen clogging rate. Alternatively, the handwheel 12 can be manually turned to drive the threaded rod 11 to rotate and move the U-shaped plate 701 up and down, adjusting the distance between the nozzle 703 and the screen to adapt to screens with different wear levels, ensuring that the cleaning force is moderate and avoiding damage to the screen or insufficient cleaning. At this time, the two ends of the U-shaped plate 701 move within the square hole, which plays a limiting role.
