Abstract

The invention discloses an environmental-friendly crushing and dedusting device for concrete wastes, and relates to the technical field of concrete processing. The environmental-friendly crushing anddedusting device for the concrete wastes comprises a treatment box, wherein support legs are fixedly connected to four corners of the bottom part of the treatment box; a feed hopper is fixedly connected to the top end of the treatment box; a primary crushing device is arranged on the top part in the treatment box; a secondary crushing device is arranged under the primary crushing device; negativepressure covers are fixedly connected to two sides in the treatment box; a negative pressure fan is fixedly connected to the outer part of the treatment box; an air purification device is connected between the input end of the negative pressure fan and each negative pressure fan; a material discharge cover is fixedly connected to the center of the bottom end of the treatment box; and a material discharge pipe is fixedly connected to the bottom end of the material discharge cover. According to the environmental-friendly crushing and dedusting device for the concrete wastes provided by the invention, through arranging the primary crushing device and the secondary crushing device for sufficiently crushing the concrete wastes, and through arranging the negative pressure covers and the air purification devices for absorbing and purifying dust produced by smashing, the environment is effectively protected.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to an environment-friendly crushing and dedusting device for concrete waste. Background technique [0002] Concrete, referred to as concrete for short, refers to the collective name of engineering composite materials in which aggregates are cemented into a whole by cementitious materials. Generally speaking, the term concrete refers to the cement concrete obtained by using cement as the cementitious material, sand and stone as the aggregate; mixed with water (may contain admixtures and admixtures) in a certain proportion, and stirred. Concrete, which is widely used in civil engineering and modern architecture. Building construction or demolition will produce a large amount of concrete waste, which is large in size and difficult to degrade, and the traditional landfill treatment method is not enough to deal with it. Therefore, concrete needs to be recycled, for example, ...
