Description

Building rubbish recycled aggregate washing purifier

Technical Field

The utility model belongs to the technical field of building material production facility, concretely relates to building rubbish recycled aggregate washing purifier.

Background

The construction waste is a multi-component mixture and contains inorganic hard components such as waste concrete, waste tiles and the like, and also contains components such as waste wood, waste asphalt, waste metal, waste plastic and the like. The construction waste is required to be respectively utilized on the basis of realizing effective separation of all components, so that the resource treatment of the construction waste is realized. The aggregate is a granular material which plays a role in skeleton and filling in concrete and mortar, and a large amount of recycled aggregate is contained in the construction waste and can be recycled. The production process of the recycled aggregate from the construction waste is based on crushing and screening, and must fully consider the separation and impurity removal process measures, and determine the aggregate shaping, strengthening process and impurity removal process according to the product application of the recycled aggregate.

The traditional light material separator aims at removing light impurities such as wood, foam and the like in recycled aggregate, the aggregate enters from a feeding port, the light materials are positioned on the upper layer of a water surface under the action of buoyancy, the light materials are discharged from a light material port through a rotating tooth hook, and heavy aggregate sinking to the bottom of the water is conveyed out through a conveyor at the bottom of the water, so that the separation of the light material impurities and the aggregate is realized. However, because the two conveyors are easy to rust after being soaked in water for a long time, fine aggregate and impurity silt at the bottom of the water tank easily enter the interior of the conveyors to influence the normal operation of the conveyors, and the failure rate of the equipment is extremely high due to severe work, and the equipment is difficult to repair; the water in the water tank is dead water, and the water needs to be replaced regularly when the water is turbid after working for a period of time, so that the water resource is wasted, and the water resource cannot be effectively recycled; the aggregate moisture content that transports is very high, and the phenomenon of flow material appears easily when piling up, influences production.

The preparation of high-quality aggregate from construction waste is a very effective way to treat construction waste at present. At present, most of construction waste treatment methods are crushing and screening, and mainly comprise sorting, coarse crushing, fine crushing, screening and the like. Although the building waste can be crushed into the aggregate with the required particle size, the light floater and other water-soluble impurities in the building waste cannot be effectively removed, so that the strength of the aggregate is greatly reduced when the aggregate is used secondarily, irregular pot holes can be formed in the surface of a secondary product due to short-time weathering of the light floater mixed in the aggregate, the strength of the secondary product is greatly reduced, the use of the aggregate of the building waste is influenced, and therefore, the research and development of a novel regenerated aggregate purification device has great significance for resource utilization of the building waste.
