Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of material screening, in particular to a high-closeness material screening device for easily agglomerated materials. BACKGROUND

[0002] Material screening is a key pretreatment process in the processing and processing of materials, which is crucial to the quality of products, and the material screening technology is constantly innovating and developing in equipment structure, screen material, automation control and other aspects, providing strong technical support for efficient and clean production of various industries. In order to protect the environment and the health of the operators, reducing dust pollution in the material screening process has also become a key concern in the material screening process. Especially for easily agglomerated materials, due to their usually small particle size, they are easily lifted by vibration and airflow during screening, and these easily agglomerated materials are prone to static electricity during processing, causing particles to adhere to each other and not to fall back to the original position when vibrating, which also aggravates dust pollution.

[0003] However, the current equipment for screening easily agglomerated materials usually uses the inflation and deflation of the inflation sealing ring to realize the sealed docking of the upper and lower assemblies at the docking position of the screening assembly and the discharge assembly, but the inflation sealing ring is easily worn or the inflation air pressure is different, which causes displacement error when the upper and lower assemblies are docked, that is, the docking surfaces of the two cannot completely abut and there is a gap, which further causes dust pollution and affects the health of the operators. Therefore, it is of great significance to provide a screening device that can adapt to the displacement error generated during the docking process of the inflation sealing ring to ensure the sealed docking of the upper and lower assemblies for screening easily agglomerated materials.
