Technical Field

[0001] This utility model relates to the field of non-metallic mineral production and processing technology, and in particular to a circular vibrating screen. Background Technology

[0002] Traditional circular vibrating screens mainly consist of a screen box, vibrator, motor, and support. The screen box is equipped with a screen mesh. After the raw material to be screened falls into the screen mesh, the screen mesh vibrates. Under the combined action of gravity and the excitation force of the circular vibrating screen, the material moves downward in a "point vibration" motion.

[0003] In the production and processing of non-metallic minerals, it is necessary to screen the minerals. The commonly used device is the circular vibrating screen. Existing circular vibrating screens emit dust during use, which can harm the health of operators. Some existing technologies can suppress dust by using water mist, but wet and sticky materials can easily clog the screen, requiring frequent shutdowns to clean the screen, which affects screening efficiency.

[0004] Therefore, those skilled in the art have provided a circular vibrating screen to solve the problems mentioned in the background art. Utility Model Content

[0023] Specifically, the material is screened by setting up a side plate 10, a screen 11, and an eccentric motor 18. A support component is set up to support the side plate 10. A water mist component is set up above the screen 11. The water mist sprayed by the water mist nozzle 20 effectively avoids dust from spreading during the screening process, making the working environment cleaner. Wet and sticky materials are prone to clogging the screen 11 and require frequent cleaning. An anti-clogging component is set up below the screen 11. The air pulse unclogging unit 22 moves along the slide 21. During the movement, the compressed airflow unblocks the screen 11, reducing the need for downtime for cleaning.

[0024] The support columns 15 are in multiple sets, and the multiple sets of support columns 15 are fixedly connected by reinforcing rods 23. Support rods 24 are fixedly installed between the outer wall of the base plate 12 and the cover plate 16.

[0026] There are multiple sets of water pipes 17, which are installed on the top of the cover plate 16. There are also multiple sets of water mist nozzles 20, which are installed on the bottom of the cover plate 16. The water mist nozzles 20 and the corresponding water pipes 17 are connected in a continuous manner. Tap water is atomized and sprayed out from the water mist nozzles 20 through the water pipes 17.

[0027] Specifically, by installing a water pipe 17 at the top of the cover plate 16, tap water is atomized and sprayed out from the water mist nozzle 20 through the water pipe 17, which suppresses the dust below and ensures a clean working environment.

[0028] The slide 21 is fixedly installed between two sets of bottom plates 12 on one side of the side plate 10, and the inclination of the slide 21 is the same as that of the side plate 10.

[0031] Specifically, an anti-slip block 27 is fixedly installed on the side of the movable plate 25 near the hollow air pipe 26. The hollow air pipe 26 is fixedly installed on the anti-slip block 27. Multiple sets of air nozzles 28 are fixedly installed on the outer wall of the hollow air pipe 26. The air nozzles 28 are connected to the hollow air pipe 26. Compressed air enters the cavity of the hollow air pipe 26 through the air supply pipe 29 and is sprayed out through the air nozzles 28 to clear the screen 11 above, which is more efficient.

[0032] In summary: By setting up side plates 10, screens 11, and eccentric motors 18, materials are screened. Support components are set up to support the side plates 10. By setting up water mist components above the screens 11, the water mist sprayed by the water mist nozzles 20 effectively avoids dust diffusion during the screening process, making the working environment cleaner. Wet and sticky materials are prone to clogging the screens 11, requiring frequent cleaning. By setting up anti-clogging components below the screens 11, and by setting up a moving plate 25 near the side of the hollow air pipe 26, an anti-slip block 27 is also fixedly installed. The hollow air pipe 26 is fixedly installed on the anti-slip block 27.
