High quality recycled aggregate recycling equipment for waste building concrete

Abstract

The invention discloses high quality recycled aggregate recycling equipment for waste building concrete. The equipment comprises an equipment box body; a storage chamber, a heating and stirring chamber, a filtering separation chamber and a water filter tank are sequentially arranged in the equipment box body from top to bottom; a feeding inlet is formed in the top of the equipment box body; the box body is communicated with a water circulation system; the waste concrete entering the storage chamber of the equipment box body in batches is stirred, crushed and heated by means of a stirring roller and microwave heating equipment at the same time in the heating and stirring chamber, is then cooled by means of the water circulation system, is separated into coarse aggregate and the fine aggregate in the filtering separation chamber by means of a two-stage vibrating screen, and is collected at an outlet; the sieve residue is filtered in the filtering separation chamber and is then dischargedoutside when becoming fine powder. The equipment provided by the invention can avoid the damage, caused by the extrusion grinding and crushing, on the aggregate in a waste concrete recycling process;by adopting a processing way of simultaneously using microwave heating and the mechanical stirring, the production efficiency is greatly increased, the production process is efficient, environmentally-friendly, the control is simple, the energy is saved, and the cost is lowered; the high quality recycled aggregate recycling equipment is beneficial to popularization.

Description

technical field [0001] The invention belongs to the field of building materials, in particular to the field of recycled building waste concrete, and in particular relates to high-quality recycled aggregate recycling equipment for building waste concrete. Background technique [0002] In recent years, my country's construction industry has risen rapidly. As a widely used building material, concrete has been mass-produced, and at the same time, the demolition of old buildings has also produced a large amount of waste concrete. On the one hand, the production of new concrete consumes a large amount of natural resources such as sand and gravel; on the other hand, the accumulation of waste concrete causes environmental pollution and affects social order. The efficient recycling of waste concrete can not only solve the environmental pollution caused by waste concrete, but also can be put into production as a raw material for new concrete, reducing the exploitation of natural sand ...

AI Technical Summary

Problems solved by technology

At present, the methods of mechanical extrusion and grinding are widely used in China to crush waste concrete. Due to its own damage and more attached cement mortar, the recycled aggregate has a large performance gap with natural aggregate, and its application range is greatly limited.
