Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of concrete preparation, and particularly relates to a sand and stone automatic sorting and cleaning integrated device for concrete preparation. BACKGROUND

[0002] At present, the quality of concrete used in construction engineering depends largely on the quality of its constituent materials, especially the cleanliness and size consistency of sand and stone. Traditional sand and stone processing methods rely on manual screening and water washing, which is not only low in efficiency, but also labor-intensive, and is difficult to meet the needs of large-scale engineering construction. With the advancement of automation technology and mechanical equipment, various sand and stone sorting and cleaning equipment has gradually appeared on the market. These devices achieve the preliminary separation and cleaning of sand and stone through different mechanical mechanisms, greatly improving work efficiency and reducing labor costs.

[0003] The existing sand and stone sorting and cleaning equipment mainly includes a vibrating sieve separator, a drum screen, a spiral sand washer and the like. Among them, the vibrating sieve separator can effectively remove small impurities in sand and stone, but cannot completely clean the surface stains; the drum screen is suitable for the classification of materials with larger particle sizes, but the cleaning effect of fine sand is not good; the spiral sand washer can better remove dirt and dust on sand and stone, but it is easy to cause resource waste when processing a large amount of sand and stone. Although these three kinds of equipment have their own advantages, they also have problems such as low efficiency and limited application range.

[0004] The common problem of sand and stone processing equipment on the market at present is that the function is single, and usually multiple machines of different types need to be equipped to complete the entire sorting and cleaning process, which increases the equipment purchase cost and maintenance difficulty. In addition, the traditional equipment has weak ability to identify foreign matters of specific size and density, which can easily lead to unqualified products mixed into the final product, affecting the overall performance of the concrete.
