Description

Technical Field

[0001] The utility model relates to the technical field of vibrating screens, in particular to a slag screening device. Background Art

[0002] The slag screening device plays an important role in engineering projects. Its function is to screen the slag, sand and gravel and other impurities in the mixed materials to meet the standards required by the project. The slag screening equipment used in the project is generally a vibrating screen. The working principle of the vibrating screen is that the vibration force generated by the vibration motor on the equipment makes the particles on the screen move relative to each other, thereby realizing the separation of impurities and particle size. As one of the indispensable equipment in engineering construction, the vibrating screen plays an important role in screening out impurities, ensuring engineering quality and improving engineering efficiency.

[0003] When the existing vibrating screen is in use, construction debris will be transported to the surface of the vibrating screen for screening. However, when the vibrating screen vibrates and filters, a large amount of dust is easily generated and floats. Since the floating dust is difficult to clean, it causes pollution to the environment around the vibrating screen. Therefore, we propose a debris screening device to solve the above problem.
