Description

Technical Field

[0001] This application relates to the technical field of tunnel engineering. Specifically, it relates to a tunnel waste residue recycling and recovery device and method. Background Art

[0002] In related technologies, there is a crusher device with the function of "waste residue recycling and utilization". As the main device for crushing mine stones, the crusher device mainly crushes stones of different sizes. When a tunnel is excavated in a mountain, a large amount of stone waste residues of different specifications are generated during the excavation of the tunnel. These stone waste residues are discarded and landfilled, seriously wasting and polluting natural resources, and are now less and less advocated. Therefore, the recycling and reuse of the stone waste residues excavated from the tunnel are proposed. Considering the economic cost, on-site crushing of the stone waste residues excavated from the tunnel at the tunnel site has become the choice of more and more tunnel engineering projects. The stone waste residues are crushed to the required particle size by a crusher and are respectively applied to the concrete precast components of the tunnel body, including precast inverted arches, precast covers, etc. There is also a part that is not used for the tunnel and is used along the project, including the needs of bridges, roads, land reclamation, etc. The application of tunnel waste residues can also be deepened, and the tunnel waste residues can be made into products required by the surrounding market to realize the output and utilization of the waste residues outside the project.

[0003] However, considering the large amount of sundries and mud accompanying the existing tunnel stone waste residues, a large amount of sundries and mud are easily attached to the traditional crushing equipment. These sundries and mud attached to the stone waste residues are likely to cause ineffective hitting and unstable waste residue particle size. While reducing the crushing quality and accuracy of the tunnel stone waste residues, it increases the maintenance and cleaning frequency and reduces the crushing efficiency of the tunnel stone waste residues.

Through the separation and screening design, sundries and mud can be screened and filtered when the tunnel stone waste residues enter and exit. At the same time, each device component can be separated or combined, which is convenient for flushing and maintaining the sundries and mud. Through the two-way control of the feeding and discharging, the conveying direction of the tunnel stone waste residues is adjustable and controllable, the effective crushing time of the tunnel stone waste residues can be controlled, the crushing accuracy of the tunnel stone waste residues is stable and controllable, and the crushing efficiency of the tunnel stone waste residues is higher.

The muck transfer assembly 300 is designed with a separation and combination structure, where the feeding and discharging drums and the crushing components can be freely combined, facilitating the cleaning of sundries and mud inside the equipment, improving the crushing accuracy and quality of the tunnel stone muck, controlling the forward and reverse rotation to control the transportation direction of the tunnel stone muck, facilitating the regulation of the crushing time of the tunnel stone muck, and improving the quality accuracy of the particle size of the tunnel stone muck. The muck backwashing assembly 500 improves the impact frequency per unit time through double reverse crushing rotation, enhancing the crushing efficiency and quality accuracy. By controlling the rotation speed and direction of the stone muck in each independent unit, the tunnel stone muck in adjacent crushing control units forms different crushing mimics during crushing, colliding with each other to improve the crushing accuracy and efficiency of the mimicked tunnel stone muck.

The circumferential gear ring 530 is screwed to the distribution cylinder frame 520. The circumferential gear 510 meshes with the circumferential gear ring 530. Through this meshing structure, while limiting the distribution cylinder frame 520, the moving load of the rotation of the distribution cylinder frame 520 is increased. At the same time, the circumferential gear 510 moves up and down to reduce the gap during the meshing process and reduce the vibration during the rotation of the distribution cylinder frame 520.

A shock-absorbing spring 743 is arranged between the partition seat 521 and the installation seat 741, and the shock-absorbing spring 743 is sleeved on the surface of the guide column 742. Specifically, through the cooperation of the shock-absorbing spring 743 and the distributed hydraulic cylinder 740, the vibration of the crushing ring gear 750 is buffered by the spring and the hydraulic pressure together, reducing the impact vibration of the tunnel stone waste, and improving the stability of the device. The crushing ring gear 750 faces the crushing insert teeth 730. For example, the distance between the crushing ring gear 750 and the crushing insert teeth 730 is controlled by the distributed hydraulic cylinder 740, further adjusting the crushing particle size of the tunnel stone waste slag and improving the precision quality of the tunnel stone waste slag.

The conical opening at one end of the material sieve cylinder 360 is aligned with the inlet and outlet of the crushing device through the material hydraulic cylinder 330, and the tunnel stone muck is poured into the material sieve cylinder 360. The material motor 350 in this direction is turned on to control the spiral blade 370 to rotate forward. Under the transportation action of the spiral blade 370, some sundries and mud are stirred and filtered and quickly flow out through the holes opened on the material sieve cylinder 360. The filtered tunnel stone muck is sent between the crushing ring teeth 750, and the crushing insert teeth 730 are controlled by the power motor 720 to rotate and crush. Under the impact of the crushing insert teeth 730 and the crushing ring teeth 750, the tunnel stone muck is broken. The distance between the crushing ring teeth 750 and the crushing insert teeth 730 is controlled by the distribution hydraulic cylinder 740 to further adjust the crushing particle size of the tunnel stone muck and improve the precision quality of the tunnel stone muck. Through the circumferential gear 510 meshing with the circumferential gear ring 530, the circumferential side of the limit distribution cylinder frame 520 is limited, so that they form independent crushing control units. The rotation speed and direction of each crushing control unit are controlled separately by the circumferential motor 540. Through the reverse rotation of the crushing ring teeth 750 and the crushing insert teeth 730, the impact rate of the tunnel stone muck per unit time is increased, and the crushing efficiency and precision quality of the tunnel stone muck are improved. When the tunnel stone muck in adjacent crushing control units is crushed, different crushing mimics are formed to impact each other, so as to improve the crushing precision and efficiency of the mimicked tunnel stone muck. When the crushing device discharges materials, the material motor 350 in the discharge direction is turned on to control the spiral blade 370 to rotate reversely. Under the transportation action of the spiral blade 370, the sundries and mud after crushing are further stirred and filtered and quickly flow out through the holes opened on the material sieve cylinder 360. The material motor 350 in the discharge direction controls the spiral blade 370 to rotate forward, which can make the crushed tunnel stone muck flow back reversely into the crushing device for further crushing, and regulate the effective crushing time of the tunnel stone muck. The material sieve cylinder 360 is controlled by the material hydraulic cylinder 330 to move away from the crushing device, and the whole device is separated, which is convenient for cleaning sundries and mud and improves the crushing quality and precision. The two-way screening design for feeding and discharging is adopted. While the sundries and mud are transported, stirred and filtered by the roller, the transportation direction of the tunnel stone muck is controlled by forward and reverse rotation, which is convenient for regulating the crushing time of the tunnel stone muck and improving the quality precision of the particle size of the tunnel stone muck. The separation and combination design is adopted, and the feeding and discharging roller and the crushing component are freely combined, which is convenient for cleaning sundries and mud in the device and improves the precision quality of the crushing of the tunnel stone muck. The hydraulic circumferential crushing design is adopted. Compared with the traditional local crushing precision control, the distance between the crushing knives is adjusted in all directions, and the crushing precision of the tunnel stone muck is accurately controlled, and the particle size error generated in the crushing process is adjusted in real time. The independent unit crushing mimic design is adopted. By doubling the reverse crushing rotation, the impact frequency per unit time is increased, and the crushing efficiency and quality precision are improved. By controlling the rotation speed and direction of the stone muck in each independent unit,When the tunnel stone waste in adjacent crushing control units is crushed, different crushing mimics are formed to impact each other, improving the crushing precision and efficiency of the mimicked tunnel stone waste. The crushing precision of the tunnel stone waste is stable and controllable, and the crushing efficiency of the tunnel stone waste is higher.
