Process and system for cleaning waste residues in quarries and building sand

Abstract

The invention provides a process and system for cleaning waste residues in quarries and building sand and belongs to building waste residue cleaning processes and systems. The cleaning process comprises the following steps: 1), enabling sand stones to enter a pool; 2), enabling clear water to enter the pool; 3), stirring; 4), discharging mud water; 5), recycling clear water; 6), recycling sand stones; 7), cleaning mud; the cleaning process comprises a sand stone cleaning device (1), a mud sedimentation device (2), a clear water recycling device (3) and a material recycling device (4). The cleaning process has the advantages as follows: only 1-3 pools, one turbine stirrer and one belt conveying device are required, repeated cleaning can be carried out until rinsing, one-time cleaning can be completed by 3-5 minutes only, and water for cleaning can be used repeatedly after being purified; the cleaning process is simple, and low in water consumption, and can efficiently reduce silt content of sand stones with high quality, meanwhile, stone powder in the waste residues in quarries is retained fully, waste residues in the quarries and building sand can be cleaned in batches and industrial production is realized.

Description

technical field [0001] The invention relates to a cleaning process and system for building material waste residue, in particular to a cleaning process and system for quarry waste residue and construction sand. Background technique [0002] Natural sand is the main constituent material of concrete and mortar widely used in civil engineering. It not only plays an important role in bearing the skeleton and improving the performance of the mixture, but also consumes a huge amount, accounting for about 25% of the total weight of concrete products and about 80% of the total weight of mortar. However, various harmful substances contained in sand will have many adverse effects on buildings, and may even lead to serious engineering accidents. Among them, the content of particles with a particle size of less than 0.08mm in the sand, that is, the mud content, is very harmful to buildings. The mud powder in the sand will hinder the effective bonding of cement stones and aggregates, red...
