A crushing device for recycling waste concrete

Abstract

The invention discloses a crushing device for recycling and preparing waste concrete, which belongs to the technical field of waste concrete recycling. A crushing mechanism is installed in a crushing box, and a pair of extrusion crushing plates move towards each other to crush the concrete blocks in the crushing cavity. Extrusion and crushing are carried out, and the crushed concrete is exported through the steel plate through the screen, and the left and right opposite and reverse reciprocating movements of a pair of crushing crushing plates effectively improve the crushing effect of the concrete block, while outside the two crushing crushing plates The end is embedded with a semiconductor refrigerating sheet, and the semiconductor refrigerating sheet cools the inner end and heats the outer end. When the crushing chamber is refrigerated, it cooperates with the spraying effect. When the water mist is cooled at a too low temperature, ice slag is formed, and the ice slag is mixed with the mixed concrete. Participating in the crushing further improves the crushing effect. At the same time, the water mist reduces the dust generated, and the heat exported to the outside is introduced to the transmission table with the conveyor belt through the hot air conduction mechanism, and the obtained concrete aggregate Dry it.

Description

technical field [0001] The invention relates to the technical field of waste concrete recycling, and more specifically relates to a crushing device for waste concrete regeneration preparation. Background technique [0002] Concrete is the largest building material used by human beings. With the rapid development of economy, urban public and civil buildings and municipal facilities are undergoing massive renovation and renovation. During the construction process, a large number of old buildings were demolished, resulting in a large amount of waste concrete (mainly including waste concrete blocks, broken bricks, etc.). Urban demolition and engineering transformation will inevitably discard a large amount of concrete. [0003] With the continuous development of the city, on the one hand, the environmental problems caused by waste concrete are becoming more and more serious. The disposal of waste concrete wastes a lot of land resources and pollutes the environment; on the other...

Problems solved by technology

[0003] With the continuous development of the city, on the one hand, the environmental problems caused by waste concrete are becoming more and more serious. The disposal of waste concrete wastes a lot of land resources and pollutes the environment; on the other hand, the raw materials of concrete—clay, stone, Sand, coal, etc. consume a lot of mineral resources and affect the environment
