Recycled aggregate shaping barrel and recycled aggregate shaping equipment using shaping barrel

Abstract

The invention relates to a recycled aggregate shaping barrel and recycled aggregate shaping equipment using the shaping barrel. The recycled aggregate shaping barrel comprises a barrel body which is provided with a shaping section and a feeding hole, wherein support parts which are in rotating and supporting fit with corresponding support seats are arranged on the barrel body; and the cross section of the shaping section is in an elliptical shape. When recycled aggregates are shaped, the barrel body is driven by a driving mechanism to rotate, and back-and-forth rollover and impact of the innerpart of the barrel body is driven by the elliptical shaping section, so that through the arrangement of the elliptical shaping section, increment on impact force of an inner wall to particles and gyratory motion amplitude and frequency of the particles in the barrel body are facilitated, so that a mortar weak layer on the surfaces of the recycled aggregates is effectively abraded and removed; andin addition, because of the elliptical structure, excessive acting force on the recycled aggregates is avoided, and the recycled aggregates are prevented from being broken, so that the shapes of theparticles of the shaped recycled aggregates are close to squircle, damage to internal structures of the aggregates is reduced to a maximum extent while the good shaping effect is realized at the sametime, and a desired shaping reinforcement effect is achieved.

Description

technical field [0001] The invention relates to a recycled aggregate shaping cylinder in the field of green building machinery and recycled aggregate shaping equipment using the shaping cylinder. Background technique [0002] my country is currently in a period of large-scale construction of foundation projects, and a large amount of concrete materials are consumed every year. It is roughly estimated that the annual consumption of concrete can reach 3 billion cubic meters. The exploitation of concrete raw materials has exhausted natural resources, and frequent natural disasters have occurred due to the destruction of forest vegetation. The production of cement as a concrete cementitious material not only consumes a large amount of natural resources and energy, but also emits a large amount of dust, carbon dioxide, sulfur dioxide and other toxic and harmful gases, which is also the main source of the greenhouse effect and the formation of smog weather. At the same time, with...
