Concrete aggregate regeneration apparatus

Abstract

The invention discloses a concrete aggregate regeneration apparatus used for construction waste and construction waste residue treatment. The apparatus comprises a frame (1), a feeding hopper (2), crushing rollers (11), stripping rollers (12), a swing plate (9) and auxiliary facilities, and the swing plate (9), the crushing rollers (11) and the stripping rollers (12) are installed in the frame (1). The concrete aggregate regeneration apparatus is characterized in that the upper portion in the frame (1) is designed to be a crushing section, the lower portion in the frame (1) is designed to be a concrete (13) stripping section, the swing plate (9) is arranged over the crushing rollers (11), and a concrete aggregate separation section comprises two stripping rollers (12) having a same rotation direction. Regenerated concrete aggregates obtained in the invention are not physically damaged, have a complete structure, and are not different from new aggregates, so the apparatus multiplies the construction waste and construction waste residue reutilization rate, and has a far lower cost than aggregate heating reduction methods, thereby the added values of construction waste and construction waste residue recycling reduction are greatly improved, and circulative utilization is truly realized.

Description

technical field [0001] The invention relates to a processing device for construction waste and construction waste residue, which relates to regenerating, reducing and reusing the aggregate. Background technique [0002] The main components of construction waste and construction waste are concrete, bricks, sand, gravel, and muck. In the process of urban construction and old city renovation, a large amount of construction waste and construction waste will be produced, and the amount has accounted for 20% of the total amount of urban waste. 30%-40%, the cumulative amount is astronomical, and a good solution to this problem is related to major livelihood issues in cities and countries in various countries, such as farmland protection, environmental protection, quality of life, energy conservation and emission reduction. [0003] At present, various comprehensive treatment schemes related to construction waste and construction waste emerge in endlessly, but there are deficiencies...

AI Technical Summary

Problems solved by technology

[0003] At present, various comprehensive treatment schemes related to construction waste and construction waste emerge in endlessly, but there are deficiencies in full utilization and benefit maximization, and the added value is low, and they cannot be truly repeated and recycled.

In terms of comprehensive treatment of construction waste and construction waste residues, foreign researches are early. For example, the heating reduction aggregate method in Japan and other countries is well done. Domestic research is relatively late. Domestic enterprises mainly use simple crushing and block The low-value-added methods of paving roads and making bricks with fine materials are either too high in cost or low in added value, which seriously affects the development of the industry

There are also many enterprises trying to restore and regenerate concrete aggregates, but due to insufficient crushing methods, the physical strength of the aggregates is damaged, and the prefabricated components fail to meet the design strength requirements.
