Description

Technical Field

[0001] The utility model relates to the field of cement processing, in particular to a screening device used for cement processing. Background Art

[0002] Cement is made of limestone, clay, iron ore and mixed materials. During the processing, the raw materials need to be screened to classify the particle size to ensure that the qualified particles in the raw materials meet the batching standards, thereby ensuring the quality of the cement. This solution specifically involves a screening device for cement processing;

[0003] When the existing cement processing screening equipment is in use, since the cement is screened by vibration, the overall vibration amplitude during screening is large, which makes it inconvenient to disassemble and clean the screen plate. After screening, the raw materials that are stuck together need to be discharged. The dust generated during the discharge is easy to spread and easily inhaled into the human body, which has a certain impact on actual use. Utility Model Content

[0023] In this embodiment, the two guide rails 5 are arranged to be inclined, and the screen plate 10 is arranged to slide between the two guide rails 5. The vibrator 7 vibrates the guide rails 5, thereby vibrating the screen plate 10 for screening.

[0024] In this embodiment, four support blocks 8 are arranged in a matrix, two guide rails 5 are supported on the top of the four support blocks 8 by springs 9, and the guide rails 5 are supported by the springs 9 and the support blocks 8. The springs 9 can reduce the vibration of the box 1.

[0025] In this embodiment, the end of the baffle 15 coincides with the slag discharge port 13, and the inclination directions of the first inclined plate 11 and the second inclined plate 12 are opposite. The baffle 15 allows the cement raw materials that are stuck together to slide to the slag discharge port 13 for collection, and the first inclined plate 11 and the second inclined plate 12 allow the cement raw materials to be concentratedly fed and screened.

[0026] In this embodiment, the dust removal mechanism 4 includes an aggregate box 18, which is installed in front of the slag discharge port 13. A conveying pipe 19 is installed on one side of the aggregate box 18. A spiral rod 20 is movably installed inside the conveying pipe 19. A motor 21 is installed at one end of the conveying pipe 19. A discharge pipe 22 is installed at one end of the outside of the conveying pipe 19. The cement raw materials that are stuck together enter the aggregate box 18, and the spiral rod 20 is rotated by the motor 21 for discharge, which can reduce the diffusion of internal dust.

The cement raw materials that are stuck together are transported to the discharge pipe 22 through the spiral rod 20 and discharged through the discharge pipe 22.

[0029] It should be noted that the utility model is a screening device for cement processing. When in use, first start the vibrator 7 to make the guide rail 5 drive the screen plate 10 to vibrate, put the cement raw material into the box body 1 through the feed hopper 2, and let the raw material fall onto the screen plate 10 through the first inclined plate 11 and the second inclined plate 12 for screening. The screened raw material is discharged through the discharge hopper 14. The vibration of the box body 1 is reduced by the support of the spring 9. When cleaning the screen plate 10, take out the insert rod 17 and remove the screen plate 10 from the two guide rails 5 through the handle 16. During the screening process, the raw materials that are stuck together slide to the slag discharge port 13. When discharging slag, the raw materials that are stuck together enter the aggregate box 18. By starting the motor 21 to rotate the spiral rod 20, the raw materials that are stuck together are transported to the discharge pipe 22 for discharge, thereby reducing dust diffusion.
