Crushing device for waste concrete regeneration preparation

Abstract

The invention discloses a crushing device for waste concrete regeneration preparation, and belongs to the technical field of waste concrete reutilization. A rolling crushing mechanism is arranged in acrushing box, a pair of extrusion crushing plates extrude and crush concrete blocks in a crushing cavity when moving oppositely, and qualified crushed concrete is guided out through a steel plate screen; the pair of extrusion crushing plates do left-right opposite and reverse reciprocating motion, so that the crushing effect of concrete blocks is effectively improved; semiconductor chilling plates are embedded in the outer ends of the two extrusion crushing plates and used for refrigerating the inner ends of the extrusion crushing plates and heating the outer ends of the extrusion crushing plates, the crushing cavity is matched with the spraying effect when refrigerated, and water mist is cooled at the ultralow temperature to form ice slag; the ice slag and mixed concrete participate in crushing together, the crushing effect is further improved, and meanwhile, generated dust is subjected to dust falling treatment through water mist, the heat guided out is guided into a transmission table with a conveying belt through a hot air conduction mechanism and used for drying concrete aggregate.

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
