System for resource utilization and disposal of building wastes

Abstract

The invention relates to a system for resource utilization and disposal of building wastes. The system can also be used for the resource utilization and disposal of solid wastes such as mineral waste residues, tailings and the like. The system comprises a material bin, a belt conveyor, a sand making machine, a lifting machine, a sand bin assembly, a material spreading machine, a vibration sieve I, a vibration sieve II, a dust removal pipeline, a primary air separator, a powder bin assembly, a dust remover, an additive bin assembly, a sealed main building, a container bag lifting machine, a powder feeding pipeline, a finished product lifting machine, a finished product bin assembly, a finished product bulk machine, an additive scale, a micro-material additive feeding hopper, a powder scale, a mixing machine, a building bulk machine, a packing machine, a packing hopper and a sand scale, wherein dust suction hoods are arranged at the upper parts of the vibration sieves; a gradation-adjustable device is arranged between the vibration sieve II, the material bin and the sand making machine; a micro-aggregate collecting and recycling device is also arranged at the upper part of a cylinder bin. Through the system for the resource utilization and disposal of the building wastes, the problems of low utilization rate and low addition value of the wastes such as the building wastes and the like can be solved; the problems of low performance quality, high water content, poor grain shape and water pollution of the regenerated machine-made sand material caused by a wet process or a simple extensive type dry process can be solved.

Description

technical field [0001] The invention belongs to the key technical field of construction waste recycling, application and preparation of recycled materials; in particular, it relates to recycling of recycled materials using construction waste, tailings, slag, slag, etc. to pulverize and prepare high-quality recycled aggregate + dry-mixed mortar Utilize technical solutions and equipment. Background technique [0002] Construction waste refers to broken concrete blocks, bricks, slag, etc. generated during building construction and demolition. During construction, 200 to 900 tons of construction waste will be generated per 10,000 square meters; 7,000 to 13,000 tons of construction waste will be generated for every 10,000 square meters of old buildings demolished. Buildings consume 42% of global water resources, 50% of energy and materials, and 48% of arable land during the life cycle of building materials production, construction, use, and demolition, and account for 50% of glo...

Problems solved by technology

[0004] One of the purposes of the present invention is to solve the above problems, and propose a construction waste resource utilization and disposal system, which solves the extensive wet process, resulting in poor performance and quality of regenerated machine-made sand materials, water content High efficiency, poor particle shape, and water pollution problems. At the same time, it solves the problem of simply arranging the solid waste sand making line and the dry-mixed mortar production line together, resulting in a large floor area, many equipment, high power and other resources. High, high energy consumption, small footprint, raw materials are only lifted once, and can rely on gravity to complete production, low energy consumption per ton, low external emission noise, no pollution to exhaust gas, recyclable steel, energy saving and environmental protection
