Abstract

The invention discloses a system for secondary preparation of reclaimed sand from concrete and a using method, and belongs to the technical field of concrete processing. The system comprises a roller, a bottom plate and two sets of supporting columns, the two sets of supporting columns are fixedly connected to the top end face of the bottom plate in a bilateral symmetry manner, and movable rods are fixedly connected to the two side ends of the roller; and movable sleeves are fixedly connected to the top end faces of the two sets of supporting columns, the movable rods are arranged in inner cavities of the movable sleeves and are in bearing connection with the movable sleeves, a crushing device is arranged above the roller, and inlet and outlet pipelines in inner cavity communication are fixedly connected to the upper end and the lower end of the roller. A sealing plate detachably connected through bolts is arranged at a pipe opening of the inlet and outlet pipeline, a transmission device is arranged at the left side of the supporting column at the left side and is in transmission connection with the roller, and a purification device is arranged at the right side of the supporting column at the right side. The system aims at solving the problem that the treatment effect of waste concrete is poor.

Description

technical field [0001] The invention relates to the technical field of concrete processing, in particular to a system and a use method for secondary preparation of recycled sand from concrete. Background technique [0002] Natural sand is a non-renewable resource in a short period of time. With the increasing development of infrastructure and the gradual implementation of environmental protection and sustainable development policies, natural sand resources are increasingly in short supply in many areas of my country, especially for concrete mixing. At the peak of sand consumption, the price of sand is high, and even there is no natural sand to provide, and the waste concrete is recycled and made into recycled aggregate (regenerated sand and gravel) to produce recycled concrete, which not only solves the shortage of natural sand and gravel, but also It is of great significance to vigorously develop circular economy and build a resource-saving society. [0003] The Chinese pate...
