Disintegration repairing device for making high quality sand and stone from construction waste

Abstract

The invention discloses a disintegration repairing device for making high quality sand and stone from construction waste. The device includes disintegration repairing mechanisms, each mechanism consists of a bracket, a barrel, a wear-resistant liner plate, an overflow grate board, 1-3 wearproof impeller material throw discs, and a main shaft. The side wall of the barrel is equipped with overflow holes, the lowermost part of the barrel is equipped with a discharge valve, the barrel is fixed on the bracket, the wear-resistant liner plate is fixed on the inner wall of the barrel body, the overflow grate board is fixed at the overflow holes, the main shaft is fixed at the center of the barrel, and the wearproof impeller material throw discs are sequentially fixed on the main shaft at interval.The disintegration repairing device provided by the invention has the characteristics of simple technological process and equipment, small land occupation, low investment, and high disintegration separation efficiency, is conducive to resource utilization and popularization of construction waste, is conducive to protecting the social ecological environment and natural environment, and is conducive to increasing employment opportunities, and also can solve the shortage problem of admixture sources in cement enterprises to a certain extent.

Description

technical field [0001] The invention relates to the technical field of environmental protection equipment, in particular to a disintegration and repairing device for making high-quality sand and stones from construction waste. Background technique [0002] As we all know, the production of cement required for engineering construction requires high energy consumption and high pollution, and consumes a large amount of non-renewable clay-type aluminosilicate minerals and calcareous minerals (such as limestone) resources; Due to the influence of mining, coupled with the gradual depletion of high-quality sand and gravel resources, the supply of sand and gravel for engineering is tight and expensive. Due to cost reasons, gravel with high mud content (especially the mud content of sand used for concrete is generally as high as 5-22%) and sand gravel with high chloride salt (sea sand generally contains 0.1-1.5% chloride salt, cleaning The sea sand containing chlorine salt is still ...

AI Technical Summary

Problems solved by technology

Although the above-mentioned method can obtain high-quality recycled sand, stone aggregates and activated cement stone materials, there are the following problems: one needs to carry out heat treatment, consumes fuel, and the decomposition of fuel combustion and limestone aggregates produces air pollution and a large amount of carbon Second, it needs to be ground by a ball mill with high energy consumption and low heat rate, which has high power consumption, low efficiency, and produces secondary pollution. Furthermore, the investment is relatively large, which is not suitable for the low investment required by the large amount of construction waste. , low-cost local centralized processing
