[0002] Solid construction waste mainly includes abandoned concrete blocks, abandoned asphalt concrete blocks, mortar, concrete and broken bricks scattered during the construction process, as well as masonry and concrete fragments produced by grooving, reinforced concrete pile heads cut by piling, metal, bamboo and wood, waste generated by decoration, various packaging materials and other wastes. These wastes can be transformed into materials or products with reuse value through a series of processing and treatment. The process of making recycled concrete aggregates from solid construction waste is an important link in resource recycling. Recycled concrete refers to the process of crushing, cleaning and grading abandoned concrete blocks, mixing them with grading in a certain proportion, partially or completely replacing natural aggregates such as sand and gravel (mainly coarse aggregates), and then adding cement, New concrete made of water, etc. This concrete uses recycling technology to process and reuse discarded concrete or building fragments. It is an environmentally friendly and sustainable building material. The existing recycled concrete aggregate equipment is usually processed by a single screening structure during the manufacturing process, so that the concrete blocks are mixed with impurities such as steel bars. When processing large amounts or high-density construction solid waste, the crushing and screening capabilities of the equipment may not be sufficient to meet production needs, resulting in low production efficiency, which will affect the quality and particle size distribution of the recycled aggregate, and thus affect the performance of the recycled concrete; therefore, we proposed a device for making recycled concrete aggregate from construction solid waste and a method for making it, in order to solve the above-mentioned problems.

[0014] According to another aspect of the present invention, there is provided an apparatus for producing recycled concrete aggregate from construction solid waste and a method for producing the same, comprising the following steps:

[0015] S1. First, put the large pieces of materials into the crushing bucket and into the crushing space in sequence. Before putting them in, the first driving motor drives the rotating rod to drive the curved frame to rotate, and the materials are separated by the dividing rod. The first driver drives the bogie to drive the pressure cover to rotate along the inside of the rotating ring. The hydraulic cylinder drives the hydraulic sleeve to drive the pressure cover to lift and lower, so that the rotating disk enters the crushing bucket, and is connected with the annular hanging plate through the installation sleeve. The distance meter is observed and measured. The second driving motor drives the rotating disk to drive the crushing drill to rotate, and the crushing process is continuously carried out;

[0016] S2. As the material is separated from the steel bar-like metal material during crushing, the second driver drives the connecting shaft to drive the swing frame to swing, the magnetic suction controller drives the magnetic suction rod to adsorb, and then the hydraulic cylinder drives the hydraulic sleeve to drive the pressure cover to lift, and the first driver drives the bogie to drive the pressure cover to rotate and swing along the inside of the rotating ring, so that the metal parts are adsorbed and transported in sequence;

[0017] S3, as the material is crushed, the motor group drives the first rotating shaft to drive the crushing frame to rotate, and cooperates with the upper structure to crush the inside into small pieces, which enter the grinding tank through the electromagnetic control valve and the transmission pipe. At the same time, appropriate softening solution is added through the liquid adding pipe. The third driving motor drives the steering rod to drive the crushing blade, the reinforcement ring sleeve and the grinding block to rotate. While the material is crushed by the crushing blade, the entry efficiency is accelerated. The telescopic cylinder drives the telescopic sleeve to rise upward along the movable groove, and the material enters the telescopic sleeve. The grinding block and the grinding ball grind the material. After a period of time, the telescopic cylinder drives the telescopic sleeve to descend along the movable groove. The material adhering to the telescopic sleeve is removed through the sealing rubber sleeve position. The synchronous material is screened through the screen barrel and enters the conveying pipe from the screen slot;

[0018] S4, the pure material pipe is connected to the filling pipe and enters the solution box, and is controlled by the connecting valve to be discharged from the conveying pipe. The discharge material is controlled by the metering device to enter the blending tank from the first discharge pipe. The fourth drive motor drives the second shaft to drive the extension rod to rotate. The fifth drive motor drives the third shaft to drive the balance plate to rotate, and finally the material is discharged through the valve on the second discharge pipe.

[0019] Beneficial effects of the present invention:

[0020] 1. According to the previous recycled concrete aggregate equipment, it is usually processed by a single screening structure, so that the concrete blocks are doped with impurities such as steel bars. When processing a large amount or high-density construction solid waste, the crushing and screening capabilities of the equipment may not be sufficient to meet the production needs, resulting in low production efficiency, which will affect the quality and particle size distribution of the recycled aggregate, and then affect the performance of the recycled concrete. The difference is that through the crushing bucket, located above the pressure-bearing component, the construction solid waste can be initially crushed. Through the pressure-bearing cover corresponding to the crushing bucket, it can be used to carry the crushing processing component. Through the crushing processing component, located in the center of the pressure cover, crushing processing and metal material screening can be performed. Through the grinding tank, located around the periphery of the pressure-bearing component, it can be used for refining and grinding aggregate operations. Through the electromagnetic control valve, located between the crushing bucket and the pressure-bearing component, the discharge can be controlled. Through the mixing tank, located below the outer side of the grinding tank, it can be used to mix recycled concrete. Through the pure material filling component, located at the upper edge of the mixing tank, the annular fixed box can be used to fill a single pure material for feeding control, thereby improving the overall processing effect.

[0021] 2. When crushing, put the large pieces of material into the crushing bucket in turn and enter the crushing space. Before putting them in, the first drive motor drives the rotating rod to drive the curved frame to rotate, and the dividing rod separates the materials to avoid blockage. The first drive drives the bogie to drive the pressure cover to rotate along the inside of the rotating ring to increase the adjustment flexibility. The hydraulic cylinder drives the hydraulic sleeve to drive the pressure cover to lift and lower, maintain smooth control, and make its rotating disk enter the crushing bucket. The second drive motor drives the rotating disk to drive the crushing drill bit to rotate for continuous crushing, forming an upper and lower processing crushing. As the crushing occurs, the material is separated from the steel bar metal material, and the magnetic suction controller drives the magnetic suction rod for adsorption. Then the hydraulic cylinder drives the hydraulic sleeve to drive the pressure cover to lift, and the metal parts are adsorbed and transported in turn to increase the separation control performance.

[0022] 3. When grinding, the material is crushed by the crushing blade, and the entry efficiency is accelerated. The telescopic cylinder drives the telescopic sleeve to rise upward along the movable groove, and the material enters the telescopic sleeve. The grinding block and the grinding ball grind the material to increase the grinding effect. After a period of time, the telescopic cylinder drives the telescopic sleeve to descend along the movable groove, and the material adhering to the telescopic sleeve is removed through the sealing rubber sleeve position to increase the cleaning effect. The material is simultaneously screened through the screening barrel to improve the screening efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
