Reinforced-concrete breaking treatment system

Abstract

The invention discloses a reinforced-concrete breaking treatment system. The reinforced-concrete breaking treatment system comprises a double-acting-jaw vibratory jaw type breaking machine (1), a hopper (2), an automatic feeding mechanism, a chain-type reinforced-concrete separating and concentrated unloading machine (3) and a unloaded-material collecting and discharging mechanism, wherein reinforced concrete is conveyed into the hopper (2) arranged above the double-acting-jaw vibratory jaw type breaking machine (1) by the automatic feeding mechanism and enters the double-acting-jaw vibratory jaw type breaking machine (1) for breaking by an opening under the hopper (2); the reinforced concrete is broken and separated into concrete blocks and steel bars which are separated by the chain-type reinforced-concrete separating and concentrated unloading machine (3) and are discharged by the unloaded-material collecting and discharging mechanism. The reinforced-concrete breaking treatment system disclosed by the invention has the advantages that the applicability to materials such as building wastes of broken ores and concrete and the like, especially the building wastes of reinforced-concrete structural parts containing steel bars can be broken and treated, the treatment difficulty can be solved, automatic continuous production can be realized, the needs of comprehensive utilization of national building wastes and green building policies can be met, the working efficiency is high and the cost can be saved.

Description

technical field [0001] This patent relates to the technical field of mechanical structures, in particular to a reinforced concrete crushing and processing system. Background technique [0002] With the rapid development of my country's economy and the advancement of urbanization, the amount of construction waste generated and discharged has grown rapidly. At present, the recycling rate of construction waste in my country is relatively low, especially the recycling rate of reinforced concrete waste is even lower. At present, some of these construction wastes can only be dumped or landfilled, and cannot be properly treated and comprehensively utilized, resulting in wasting resources, occupying land, polluting the environment, and affecting the coordinated development of people's lives and the ecological environment. [0003] Most of the main load-bearing components of buildings in my country are constructed with reinforced concrete structures. Reinforced concrete structure i...

AI Technical Summary

Problems solved by technology

However, after a building is demolished, the resulting reinforced concrete waste is more difficult to dispose of than concrete, bricks, hollow-core slabs, etc.

The first reason is that reinforced concrete waste contains steel bars and is difficult to handle. During the crushing process, when the steel bars in the waste reinforced concrete waste enter common jaw crushers, impact crushers, hammer crushers and other equipment, they will Cause equipment damage, so it is difficult to use existing equipment and methods to achieve continuous crushing of waste reinforced concrete waste

The second reason is that it is not easy to complete unloading and transportation. The steel bar has high hardness and toughness. Even if the reinforced concrete waste is broken and separated into small concrete pieces and steel bars, it is not easy to unload. If a belt conveyor is used, the steel bar will make the belt conveyor If the tape is damaged, it cannot continue to complete the unloading and conveying work; if it is discharged directly, the crushing equipment needs to be placed at a higher height due to the large length of the steel bar, so that the steel bar can be discharged smoothly, and the steel bar and concrete after discharge It also needs manual or magnetic separation equipment to achieve separation, which affects the efficiency and cost of processing
