Description

Technical Field

[0001] The present invention relates to the technical field of construction waste recycling and treatment, and in particular to intelligent sorting, crushing and grinding equipment for recycled aggregates of construction waste and a full-process control and preparation system. Background Art

[0002] The intelligent sorting, crushing, grinding and whole process control preparation system of construction waste recycled aggregate is designed to solve this problem. It is a technical system specially designed to process construction waste and convert it into reusable resources. The system converts construction waste into high-quality recycled aggregates through a series of complex process flows, including sorting, crushing, screening and cleaning. These recycled aggregates can not only be used to produce concrete and mortar, but also to make blocks, wall panels, floor tiles and other building materials, thereby realizing the resource utilization of construction waste. The application of this system not only reduces the negative impact of construction waste on the environment, but also helps to save natural resources and reduce the exploitation and consumption of natural resources. In addition, it is in line with the strategy of sustainable development. By recycling resources, it reduces the generation of waste and reduces the pressure on the environment. At the same time, due to the relatively low production cost of recycled aggregates, it also brings economic benefits to the enterprise, achieving the dual goals of environmental and economic benefits.

[0003] At present, one of the main shortcomings of the recycled construction waste raw aggregate system is its insufficient degree of automation, which requires more manual participation in the processing process. This inefficient and low-quality processing method not only limits the application scenarios of recycled aggregates, but also causes a certain degree of environmental pollution and waste of resources. The recycled aggregate system also has shortcomings in the level of intelligent processing. The lack of a systematic and automated recycled aggregate sorting and preparation production line has resulted in a large amount of dust, soil or fine sand generated during the screening of recycled aggregates not being effectively processed. These problems not only affect the performance and safety of recycled aggregates, but also limit their widespread application in the construction field.

[0004] Therefore, faced with problems such as inefficiency, environmental pollution, and waste of resources in the process of construction waste treatment, how to propose a highly intelligent and automated construction waste recycled aggregate intelligent sorting, crushing, grinding, and full-process control and preparation system to achieve efficient treatment and resource utilization of construction waste has become a technical problem that technical personnel in this field urgently need to solve. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent sorting, crushing and grinding equipment for recycled aggregates from construction waste and a full-process control and preparation system that solves the above-mentioned technical problems.

[0006] In order to solve the above technical problems, the present invention provides a full-process control and preparation system for intelligent sorting, crushing and grinding equipment of recycled aggregate from construction waste, comprising the following steps: Step 1: Construction waste is sent into the inside of the intelligent sorting device through the inner side of the conveyor belt; the inner side of the intelligent sorting device includes the inner side of the mechanical frame, the inner side of the sensor and the inner side of the mechanical arm; the inner side of the sensor automatically identifies debris in the waste, and the inner side of the mechanical arm is connected to the inner side of the mechanical frame so that the inner side of the mechanical arm can grab and remove the debris; Step 2: The sorted materials enter the inner side of the intelligent eccentric roller crusher for primary crushing; the inner side of the intelligent eccentric roller crusher is used to crush large pieces of materials; Step 3: After the material is crushed, it is sent to the inside of the intelligent magnetic separator through the inside of the dust-proof conveyor belt. The inside of the dust-proof conveyor belt is installed with the inside of the dust cover and the inside of the spray pipe, and the dust concentration is monitored through the inside of the dust sensor; the inside of the intelligent magnetic separator includes the inside of the rotating disc and the inside of the electromagnet, which are used to remove iron debris; Step 4: The preliminarily processed materials enter the intelligent cone crusher through the inner side of the dust-proof conveyor belt for further crushing; Step 5: Send the material to the inside of the intelligent magnetic separator again through the inside of the dust-proof conveyor belt for secondary iron removal; Step 6: The material then enters the inner side of the air separator and the vibrating screen to further separate materials of different particle sizes.

[0007] The beneficial effects of the present invention are: 1) The intelligent sorting, crushing, grinding and whole-process control and preparation system for recycled aggregates from construction waste realizes the automation and intelligence of construction waste treatment by integrating key components such as intelligent sorting devices, intelligent jaw crushers, intelligent magnetic separators, dust-proof conveyor belts, and intelligent cone crushers. The system can automatically identify and remove debris from the garbage, effectively improving sorting efficiency and accuracy and reducing the need for manual intervention.

[0008] 2) An intelligent control system is used during the crushing process to monitor dust concentration in real time and automatically adjust the operation of the vacuum cleaner, thereby strictly controlling the emission of pollutants such as noise and dust. This intelligent regulation not only helps protect the environment, but also improves the working environment and ensures the health of operators.

[0009] 3) The combination of dust-proof conveyor belt and spray pipe further reduces the generation of dust during material transportation and improves dust reduction efficiency. The dust cover made of transparent material makes it simple and intuitive to monitor the working status of the conveyor belt, while the fine atomization nozzle expands the coverage area of ​​the water mist and enhances the dust reduction effect.

[0010] 4) The electromagnet of the intelligent magnetic separator is in the shape of a round cake, which provides a larger contact area and stronger attraction, significantly improving the iron removal efficiency.

[0011] 5) The system improves the durability and maintenance convenience of the equipment through a series of optimized materials and designs, such as self-lubricating bearings, mechanical clamps with serrated edges, and vibration plates composed of multiple steel plates. These designs not only extend the service life of the equipment, but also reduce operating costs.

[0012] 6) The application of intelligent sorting technology enables the efficient recovery of valuable materials in construction waste and improves sorting accuracy. The whole process control system ensures that every link from sorting to finished products is under strict monitoring, improving the stability and reliability of the system.
