Description

Building sand cleaning system

Technical Field

The utility model relates to the field of sand washing equipment, in particular to a building sand cleaning system.

Background

In construction works, concrete and construction mortar are used in large quantities. The building sand is used as an important component in concrete composition and is widely applied to construction engineering: sand is a fine aggregate of concrete, accounting for about one third of the weight of concrete, and is also an aggregate of building mortar. The strength, surface activity, grading, particle shape and cleanliness of the sand, and the content of harmful substances such as organic matters, mud blocks, chloride ions and the like influence the workability, strength and durability of the concrete to a great extent, and are directly related to the quality safety of construction engineering.

The building sand comprises natural river sand, machine-made sand and mixed sand, the river sand is used as a fine aggregate of the concrete since the concrete is invented, and the river sand is proved to be the cheapest, safest, most reliable and best durable fine aggregate of the concrete by more than one hundred years of use. However, with the use of large-scale construction, the sand source of high-quality river sand has been substantially exhausted, and people have begun to utilize secondary river sand containing a large amount of impurities, machine-made sand produced by crushing mountain-opening rocks, and sea sand. But the available river sand contains basically more impurities; the machine-made sand has more needle sheets and shuttle angles, the grinding roundness of a sand body is poor, and meanwhile, the surface of the sand grains or the surface of the sand grains contains fragments or weathered layers, so that the workability is poor and the durability is also influenced; sea sand contains a large amount of chloride ions and other harmful substances, and the durability and safety of engineering are influenced. Therefore, the sand must be further cleaned and disposed of for safe use.

At present, the main equipment for cleaning the building sand is still the traditional cleaning equipment for cleaning the river sand. These devices are mainly: spiral sand washers, bucket wheel sand washers, drum sand washers, bucket chain sand washers, and the like.
