[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below with reference to the examples. The examples are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0022] In the following embodiments, the primary crushing roller 10, the secondary crushing roller 12, the first feeding auger 7 and the second feeding auger 25 are all driven by independent motors.

[0023] Concrete solid waste recycling equipment is used to process and recycle concrete waste generated during construction or demolition. Its purpose is to process waste concrete into reusable resources, such as recycled aggregate or recycled concrete, for use in new construction projects or other applications. This type of equipment is typically used in environmental protection applications, construction sites, or waste treatment plants.

[0024] However, in the recycling process, concrete solid waste is usually put into the machine, crushed, discharged, and then recycled and reused. The overall recycling effect is low. The present application uses a multi-stage processing component to perform secondary processing on the material, which has a better processing effect. The set dividing plate 11 is used to make the secondary crushing rollers 12 on both sides work simultaneously, thereby improving efficiency.

[0025] Therefore, according to Figure 1-Figure 5As shown, this embodiment proposes a concrete solid waste resource recycling equipment, including a recycling machine shell 1, and the recycling machine shell 1 is provided with a processing chamber 2, a feeding chamber 3, an installation chamber 4, a dust removal chamber 5 and a sorting chamber 6. This equipment integrates the functions of crushing concrete solid waste and then performing magnetic separation, which is convenient for separating the metal material and concrete material in the concrete solid waste. At the same time, during the crushing process, the smoke and dust generated can be absorbed, filtered, and then discharged, reducing the impact of dust on the external working environment. Furthermore, this device also has the function of outdoor work, and a load-bearing plate 27 is installed on the inner side of the installation chamber 4, and a diesel generator 28 is installed on the load-bearing plate 27 to provide the power required by this equipment.

[0026] Protective doors are installed on the recycling machine housing 1. There are four groups of protective doors, which correspond to the positions of the processing chamber 2, the installation chamber 4, the dust removal chamber 5 and the sorting chamber 6 respectively.

[0027] The processing chamber 2 is equipped with a multi-stage processing assembly, and the processing chamber 2 is connected to the feeding chamber 3. Figure 2 As shown, the multi-stage processing component includes two groups of symmetrically arranged primary crushing rollers 10. A feed port is provided at the upper end of the recycling casing 1, and the position of the feed port corresponds to the position of the primary crushing roller 10. During operation, the staff uses an external feeding device to put the concrete solid waste into the feed port, and it is crushed for the first time by the primary crushing roller 10.

[0028] A separator plate 11 is provided directly below the two sets of primary crushing rollers 10, and the separator plate 11 is connected to the recycling machine housing 1 via an elastic component. Secondary crushing rollers 12 are provided on both sides below the separator plate 11, and two sets of secondary crushing rollers 12 are symmetrically provided on each side. That is, in this embodiment, there are a total of four sets of secondary crushing rollers 12. Both the primary crushing rollers 10 and the secondary crushing rollers 12 are provided with raised structures. After the first crushing operation, the material falls and contacts the separator plate 11. In this embodiment, the cross-section of the separator plate 11 is triangular, so the separator plate 11 guides the material to the left and right sides, thereby entering the working area of ​​the secondary crushing rollers 12. In this embodiment, the density of the raised structures on the secondary crushing rollers 12 is less than the density of the raised structures on the primary crushing rollers 10. Therefore, the primary crushing rollers 10 are for coarse processing, while the secondary crushing rollers 12 are for fine processing. Consequently, in this device, through the multi-stage processing components, the concrete solid waste can be processed more finely. Accordingly, the processed material falls into the feed chamber 3 under the action of gravity.

[0029] A first feeding auger 7 is installed in the feeding chamber 3, and the feeding chamber 3 is connected to the sorting chamber 6. The first feeding auger 7 transports the logistics in the feeding chamber 3 to the sorting chamber 6. A guide barrel 8 is installed on the inner side of the sorting chamber 6, and a magnetic attraction component is installed on the guide barrel 8. The magnetic attraction component includes two groups of symmetrically arranged mounting plates 21. The mounting plates 21 are directly attached to the outer side of the guide barrel 8. In this embodiment, the cross-section of the guide barrel 8 is rectangular. A magnet block 22 is installed on the inner side of the mounting plate 21. The magnet block 22 passes through the inner wall of the guide barrel 8 and has a certain adsorption effect on the passing metal material. At the same time, a magnet column 23 is installed on the mounting plate 21, and the magnet column 23 is provided in several groups. One end of the magnet column 23 passes through the guide barrel 8. Therefore, in the process of the material falling, the metal material is adsorbed by the magnet column 23, thereby achieving a magnetic separation effect on the concrete solid waste. Accordingly, the material that has not been adsorbed is discharged first. After being discharged, the staff pulls out the mounting plate 21. Then, during the movement of the magnet column 23, the adsorbed material will be blocked by the inner wall of the guide barrel 8 and will remain in the guide barrel 8. As the magnet column 23 is completely moved out, the magnetic force is insufficient and the adsorbed material falls off and is then discharged.

[0030] A discharge assembly is installed at the lower end of the guide cylinder 8. The inner cavity of the guide cylinder 8 is connected to the feed cavity 3 and the discharge assembly. The discharge assembly includes a discharge shell 24. The discharge shell 24 is fixedly connected to the recycling machine shell 1. The upper end of the discharge shell 24 is connected to the guide cylinder 8. A second feed auger 25 is installed on the inner side of the discharge shell 24. A discharge port 26 is provided on the recycling machine shell 1, and the position of the discharge port 26 corresponds to the second feed auger 25. When working, a recovery trolley needs to be set up externally, and its position should correspond to the position of the discharge port 26 for collecting materials discharged by this equipment.

[0031] The inside of the processing chamber 2 is provided with a vent 9, and the vent 9 is provided in several groups. In this embodiment, the vent 9 is symmetrically provided in two groups. A dust removal assembly is installed in the dust removal chamber 5, and the input end of the dust removal assembly is connected to the vent 9 via a pipe. The dust removal assembly includes a dust removal box 17, a sealed door is installed at the upper end of the dust removal box 17, a partition is installed on the inside of the dust removal box 17, and a fan 18 is installed below the partition. A mounting ring 19 is provided above the partition and is fixedly connected to the dust removal box 17. A dust bag 20 is provided on the inside of the dust removal box 17 and is connected to the mounting ring 19 via bolts. During operation, the fan 18 is started, causing the dust removal box 17 to be in a negative pressure state. As a result, the dust generated in the processing chamber 2 is sucked in by the vent 9 and the pipe, and filtered through the dust bag 20. The treated gas is then discharged to reduce the impact of the dust on the surrounding environment. In this embodiment, an exhaust port is provided on the recycling machine housing 1, which is connected to the output end of the fan 18 through a pipe, while the input end of the fan 18 is connected to the partition through a pipe and communicates with the inner cavity of the dust removal box 17. Furthermore, a protective net is installed on the inner side of the vent 9.

[0032] The elastic component includes a fixed seat 13, on the inner side of which is mounted a spring 14, and the springs 14 are evenly arranged in several groups. In this embodiment, the springs 14 are evenly arranged in two groups. The upper end of the spring 14 is connected to the material distribution plate 11, and its lower end is connected to the fixed seat 13. The lower end of the material distribution plate 11 is mounted with an extension column 15, and the lower end of the extension column 15 passes through the fixed seat 13 and is mounted with a tamping head 16. In this embodiment, the extension column 15 is only capable of vertical movement. A material guide cover 29 is mounted on the inner side of the corresponding processing chamber 2. The position of the tamping head 16 corresponds to the position of the lower end of the material guide cover 29, and the lower end of the material guide cover 29 corresponds to the communication port between the processing chamber 2 and the feed chamber 3. During operation, the dividing plate 11 is in contact with the material. When the material falls, it will collide with the dividing plate 11. Then, under the action of the spring 14, the dividing plate 11 will float up and down as the impact force of the material changes, and then drive the ramming head 16 to move up and down. The position of the ramming head 16 corresponds to the position of the lower end of the material guide cover 29 (that is, the connecting port between the processing chamber 2 and the feed chamber 3). During its up and down floating process, it can play a certain dredging effect and avoid blockage at the connecting port as much as possible.
