Construction waste separating, recycling and reutilizing system and technique

Abstract

The invention relates to a construction demolished waste separating, recycling and reutilizing system and production technique, in particular to innovation of screening and crushing technological processes in traditional devices and production procedures. In the screening process, a roll screen, a drum screen and a vibrating screen are used to conduct classified screening, a bevel hammer even crushing technique is adopted to the crushing process at the same time, and then materials are subjected to rubbing and peeling treatment. According to the system and the technique, by designing crushingand peeling mechanisms, the crushing and peeling recovery rate of materials with different purposes in original waste resources is improved, effective classified treatment of construction waste is achieved, and therefore the maximized reutilization of resources is achieved.

Description

technical field [0001] The invention relates to a process and technology for separating, recycling, and reusing construction demolition waste, and belongs to the technical field of construction waste treatment. Background technique [0002] At present, a large amount of solid construction waste such as bricks, stones, tiles, and concrete bodies is produced in my country due to construction activities such as old city renovation, new rural construction, shantytown and dilapidated house renovation, and demolition of illegal buildings. These garbage also contain sand, stone, and steel bars. Reusable resources such as wood and wood cannot be reused directly because of their irregular shapes and sizes, and their properties are not uniform. Corresponding to this is the rigid demand for construction. Resources such as river sand, stones, earth bricks, and steel have been exploited in large quantities, and some mineral resources are even on the verge of exhaustion. This triggers pric...

Problems solved by technology

[0002] At present, a large amount of solid construction waste such as bricks, stones, tiles, and concrete bodies is produced in my country due to construction activities such as old city renovation, new rural construction, shantytown and dilapidated house renovation, and demolition of illegal buildings. These garbage also contain sand, stone, and steel bars. Reusable resources such as wood and wood cannot be reused directly because of their irregular shapes and sizes and inconsistent properties.

Corresponding to this is the rigid demand for construction. Resources such as river sand, stones, earth bricks, and steel have been exploited in large quantities, and some mineral resources are even on the verge of exhaustion. This triggers price leverage, causing the price of building materials to soar all the way, directly causing construction costs. the rise

Conventional measures such as crushing, screening and separation are generally used in the construction waste treatment equipment and technology in the prior art, which cannot effectively and thoroughly extract and utilize useful resources in construction waste, and the stripping effect is poor, resulting in certain waste of resources
