Abstract
Description
Technical Field
[0001] This utility model relates to the field of aggregate screening technology, and in particular to an anti-clogging vibrating screen for aggregate screening. Background Technology
[0002] Aggregates, also known as aggregates, are granular materials that act as a skeleton and filler in concrete and mortar building materials. They are one of the most widely used raw materials in construction engineering and have a significant impact on the strength and durability of building structures. Aggregates form the skeleton of concrete and, together with cement paste, constitute the concrete mixture. After hardening, they form artificial stone with certain strength and durability. Aggregates not only bear loads but also limit the shrinkage of cement paste, improving the volume stability of concrete. Aggregates are used in road base and surface layers to enhance the load-bearing capacity and wear resistance of roads. In asphalt concrete pavements, aggregates combine with asphalt to form a pavement structure with good skid resistance and durability. Aggregates can also be used to prepare mortar, concrete products, and as railway ballast, playing an important role in various engineering fields. To prevent aggregate screens from clogging, a vibrating screen for aggregate screening is needed.
[0003] Currently available aggregate screening anti-clogging vibrating screens mainly consist of the screen body, elastic elements, and cleaning devices. In construction, precise screening of sand and gravel is required to meet the production needs of concrete of different strength grades. Anti-clogging vibrating screens can effectively avoid the problem of low screening efficiency caused by screen clogging, ensuring the continuity of concrete production. However, unreasonable structural design of vibrating screens leads to resonance during vibration, insufficient rigidity of the supporting structure, deformation during vibration, and noise generation. To solve these problems, existing technologies only optimize the structure of the vibrating screen to avoid resonance and strengthen the rigidity of the supporting structure, such as increasing the cross-sectional area of beams and columns to improve the stability of the supporting structure. However, they do not improve the screen structure, resulting in the screens only being suitable for screening specific types and properties of aggregates. This limits the applicability of the equipment, increases equipment investment and management costs, and fails to meet usage requirements. Utility Model Content
