Description

AI applied crushing and sorting system and recycling aggregate production method using the same}

The present invention relates to the field of producing recycled aggregate using waste concrete.

In particular, it relates to a recycled aggregate production method that applies AI to the aggregate selection and crushing system. More specifically, it is a cycle in which construction waste is produced through a continuous processing process to meet the quality standards of recycled aggregate through a physical or chemical treatment process. Aggregates are managed and executed using AI technology, and the quality of the final produced recycled aggregate is also evaluated using AI technology to enable the production of high-quality products, resulting in aggregates that meet the Ministry of Land, Infrastructure and Transport's "Recycled Aggregate Quality Standards". It is about an AI-applied crushing and sorting system that enables the production of recycled aggregates and a method of producing recycled aggregates using it.

Generally, when trying to produce recycled aggregate using waste concrete from construction waste, the recycled aggregate produced by crushing and sorting waste concrete has a large amount of cement paste attached to the surface of the aggregate, so the more this is removed, the higher the quality of the recycled aggregate. It can be. The more cement paste attached to the surface of the aggregate, the higher the water absorption rate, which determines the quality of the aggregate, and the lower the absolute dry density, making it less likely to meet the quality standards of recycled aggregate for concrete. Therefore, it is used for low-quality applications such as auxiliary base or landfill. As a result, the economy and efficiency relative to production costs are generally reduced.

Looking at the production system of recycled aggregate produced by crushing and sorting waste concrete, the primary and secondary crushing of waste concrete mainly uses a jaw crusher or double jaw crusher that performs rough crushing, and primary screening is performed using a vibrating screen. , recycled aggregates larger than the product size are crushed 3rd or 4th time by installing a cone crusher, impact crusher, or roll crusher. Sometimes, to produce recycled fine aggregate, the -5mm stone dust produced first is put into the sand production process, and the concrete paste is made by crushing and screening by wet or other methods to remove the concrete paste attached to the surface of the fine aggregate. The fine particles are separated and removed to produce standardized recycled fine aggregate.

In order to reduce the cement paste attached to the surface of recycled aggregate, various crushers are used, and recycled aggregate is produced by selecting crushed aggregate to an appropriate size using a horizontal or inclined vibrating screen. However, in this way, waste concrete is produced. When producing recycled aggregate by crushing, the composition ratio and properties of the input waste concrete vary, but it is crushed with a similar crusher at a certain plant and sorted using a similar vibrating screen, so it does not reflect the characteristics of the input waste concrete and is used as cement. There was a problem in that the separation of the paste was not efficient, and as a result, high-quality recycled aggregate could not be produced.

Republic of Korea Patent Publication No. 10-2013-0126819 (May 14, 2014)

The present invention is intended to solve various problems of the prior art, and in the process of continuous crushing and selection, the crushing process is performed through 1st, 2nd, and 3rd crushers, and the crushed waste concrete lumps are passed through 1st, 2nd, and 3rd vibrating screens. This is a process in which the aggregate is selected and separated into coarse aggregate, fine aggregate, and fine powder. The plant operator directly checks and performs the work. Work assistants are placed at important inspection points for each process, or frequently checked through CCTV, etc. Work is being carried out while closely monitoring progress and safety conditions. This work is an industry that generates considerable noise, vibration, and dust, and there are many sites in dangerous environments where major disasters can easily occur.

Therefore, users want to introduce automation technology, and leading domestic companies are already automating a significant portion of the process. However, overall productivity often depends on the ability of skilled plant operators and the skills of heavy equipment operators responsible for loading and unloading, so achieving all goals of environmental protection, safety management, and productivity improvement is still far away. In particular, since this industry is a typical 3D industry, the workers are older and there are many foreign workers, so accidents caused by man-made disasters or industrial accidents frequently occur.

Therefore, these processes are managed, supplemented, progressed and recorded with AI technology, and when the aggregate produced through this process is loaded on the product transfer conveyor and transferred to a separate yard or bin, the aggregate transfer belt of the belt conveyor High-resolution optical cameras are installed at various locations above, high-speed photography is performed at set time intervals, and the data is transferred to an AI judgment computer that has been trained in advance using technology such as machine learning to determine the absorption rate and absolute dryness of the passed recycled aggregate. Apply AI to predict and determine specific gravity, and if the water absorption rate and absolute dry specific gravity do not reach the target value, transport it using a device such as a conveyor belt conveyor and then re-crush it to produce high-quality recycled aggregate. We aim to provide a crushing and sorting system and a method for producing recycled aggregate using it.

The AI sorting and crushing system of the present invention to solve the above problems and the recycled aggregate production method using the same are a process of continuously crushing and sorting waste concrete, in which the waste concrete is crushed through a crusher and the crushed waste concrete lumps are selected on a vibrating screen. Therefore, we plan to introduce and implement automation technology that does not require workers to check the process of separating coarse aggregate, fine aggregate, and fine powder.

These processes are managed, supplemented, progressed and recorded using AI technology, and when the aggregates produced through this process are transferred to a separate yard or bin using a product transfer conveyor, they are placed on the belt that runs on the belt conveyor. High-resolution optical cameras are installed in several locations, high-speed photography is performed at set time intervals, the data is transferred to an AI judgment computer trained in advance with AI technology, and the properties of the recycled aggregate being transported by the belt conveyor are monitored in real time. By predicting and analyzing, the weight of the passing recycled aggregate and the loaded recycled aggregate are empirically compared and calculated through devices such as load cells, and using this, the water absorption rate and absolute dry specific gravity are predicted, so that the water absorption rate and absolute dry specific gravity are at the target values. If it cannot be reached, it is transferred to an arbitrarily designated crusher using a device such as a conveyor belt for re-crushing, allowing the cement paste to be removed as much as possible, producing high-quality recycled coarse aggregate and high-quality recycled fine aggregate. We aim to provide an AI-applied crushing and sorting system that can continuously produce and a recycled aggregate production method using it.

As described above, in the present invention, the plant operator performs the work while directly checking, and checks by placing a work assistant at important inspection points for each process, or through CCTV, etc., and closely monitors the process progress and safety status. The process is in progress. This work is an industry that generates considerable noise, vibration, and dust, and there are many sites in dangerous environments where major disasters can easily occur. Therefore, users want to introduce automation technology, and leading domestic companies are already automating a significant portion of the process. However, overall productivity often depends on the ability of skilled plant operators and the skills of heavy equipment operators responsible for loading and unloading, so achieving all goals of environmental protection, safety management, and productivity improvement is still far away. In particular, since this industry is a typical 3D industry, the workers are older and there are many foreign workers, so accidents caused by man-made disasters or industrial accidents frequently occur. Therefore, these processes are managed, supplemented, progressed and recorded with AI technology, and when the aggregate produced through this is loaded on the product transfer conveyor and transported to a separate yard or bin, etc., several devices are placed on the aggregate transfer belt of the belt conveyor. A high-resolution optical camera is installed at the location, high-speed photography is performed at set time intervals, and the data is transferred to an AI decision computer trained in advance using machine learning technology to predict the absorption rate and absolute dry specific gravity of the passed recycled aggregate. Therefore, if the water absorption rate and absolute dry specific gravity do not reach the target value, the recycled aggregate production method using AI can produce high-quality recycled aggregate by transporting it using a device such as a conveying belt conveyor and then re-crushing it. Therefore, it is an AI-applied crushing and sorting system that reduces safety accidents, greatly increases productivity, and provides excellent environmental protection, and a method of producing recycled aggregates using it.

The AI-applied crushing and sorting system of the present invention and the recycled aggregate production method using the same are used when waste concrete chunks generated from demolition of reconstruction sites or other concrete facilities are received at a construction waste intermediate treatment plant, using heavy equipment such as dump trucks or excavators. Loading a lump of waste concrete into the hopper (1) and controlling the amount of vibration and the rotation speed of the motor to inject an appropriate amount of waste concrete loaded into the hopper (1) into the primary jaw crusher (3). A vibrating feeder (2) is installed to control the input amount.

At this time, the vibrating feeder (2) has a size adjustment bar (21) that removes waste concrete lumps or waste soil of a smaller size than the crushed size that passed through the primary jaw crusher (3), which is the primary crusher, and passes them downward. It is preferable to input the waste concrete lump into the primary jaw crusher (3) while controlling the input amount.

The primary jaw crusher (3) is operated by setting the narrowest discharge area at the bottom of the crushing unit to the smallest crushing size. Typically, the primary crushing setting value is set to 1/4 the size of the input. It operates. In some cases, in some sites, a small plate feeder (31) or a short belt conveyor (not shown) is used at the lower part of the primary jaw crusher (3) to crush the large and rough waste concrete crushed in the primary jaw crusher (3). There is also an example of protecting a conveyor belt that is prone to damage.

The coarsely crushed waste concrete that has passed through the primary jaw crusher (3) is passed through the coarsely crushed waste concrete transfer belt conveyor (B1) to the first crusher, which is equipped with the 40 mm net (41) at the top to sort the waste soil in the first stage.

It is characterized by including a general control means (A28) that executes the operation, control, judgment, and recording of all plants with AI.

At this time, it may be installed in the driver's cabin or a separately designated location, and the general control means (A28) includes the general automatic control panel unit (A21), the general manual control panel unit (A21'), and the first input unit ( A23), software (A281) and hardware (A282) that manage and instruct all of the reading unit (A24), the first indicating unit (A25), the secondary input unit (A26), and the final indicating unit (A27). It is characterized by being comprised including.

At this time, the overall control means (A28) uses AI computer vision (A30) that enables the computer constituting the software (A281) and the hardware to interpret visual images by having the ability to see, and specializes in visual images. Using knowledge and a description of the object to be observed, first find meaningful and important elements in the shape of the recycled aggregate, such as the outline or some areas of the part where a lot of concrete paste is attached, and then predict the important properties of the larger and general recycled aggregate. It consists of the algorithm of the program (A33) that finds aggregates suitable for the Ministry of Land, Infrastructure and Transport's "Recycled Aggregate Quality Standards*", which synthesizes all entities that are read and verified.

For example, if we limit the explanation to the program (A34) that finds the water absorption rate and absolute dry specific gravity, which are indicators of important qualities of recycled aggregate, the first thing to look at is the appearance of the part where pure aggregate and waste concrete paste are attached, the shape of each part, and the detailed surface. First, look for important factors such as the appearance, the degree to which the color of the surface area that absorbs water changes at a given time when spraying appropriate water, and the results of checking the degree of reflection or degree of heat content after shining a laser or infrared light. So, by utilizing a machine learning approach using a neural network in advance, preferably a special neural network called convolutional neural nets (CNN) (A32), the quality of 25 mm recycled aggregate is determined by the Ministry of Land, Infrastructure and Transport's "Recycled Aggregate Quality Standards". *" is compared with big data data (A36) that creates a standard aggregate model from a collection of data (A35) of aggregates suitable for ", and determines whether the water absorption rate and absolute dry specific gravity pass or not. . In particular, the convolutional neural network finds patterns in small areas where images overlap, and expands the 'learned' facts first to parts neighboring the pattern, and then gradually to wider areas within the image, so it is a standard. It will be possible to compare the quality of the 25mm passed aggregate and the produced aggregate. Of course, it will be necessary to continue to supplement and correct mutual comparison through continuous experiments on the absorption rate or absolute dry gravity of recycled aggregate determined by the general control means (A28) through initial machine learning (A31).

In particular, various information input from the first input unit (A23), the reading unit (A24), the first indicating unit (A25), the secondary input unit (A26), and the final indicating unit (A27) are ' By accepting the light reflected on a three-dimensional surface as a two-dimensional flat image and then reinterpreting or reconstructing the model in the original scene, it will be possible to judge recycled aggregate as pass or fail, and determine the material quality of the area to be explored. The characteristics are sufficiently understood, the signals used to project this area into an image can be collected, and the collected signals can be processed using computer vision technology. All of this is possible in principle without the scene or image being in a material form. It is an AI-applied crushing and sorting system using machine learning and convolutional neural networks and a recycled aggregate production method using it. In other words, as long as the region complies with established rules and the image reflects low-dimensional data points corresponding to elements of the region, the data can be processed to determine the structure of the region. This structure can be viewed from multiple perspectives (three-dimensional perspective), such as the shape and material of the concrete paste attached to the surface of the recycled aggregate and the properties of the wet state, geometry and physics knowledge about light, reflectivity of various surfaces, and the real world. The scene will be reconstructed based on non-existent characteristics, and while the human eye or most cameras extract samples from reflected light, various types of sensors utilize various methods to cover a range of realities that humans cannot see. World data can be collected, such as infrared oscillator (A37) and infrared receiver (A37'), radar oscillator (A38) and radar receiver (A38'), ultrasonic oscillator (A39) and ultrasonic receiver ( A39'), X-Ray oscillator (A40) and Using the device (A42'), the ultra-wide band wave oscillator (A43), and the ultra-wide band wave reception device (A43'), information that can be obtained from the various types of wavelengths described above is transmitted and received, and the same basic rules are used. If the technology is applied appropriately, it is possible to interpret or reconstruct the properties of recycled aggregate through various signals that are invisible to the human eye.
