Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0034] In the description of this disclosure, it should be noted that, unless otherwise expressly specified and limited, the terms "installed," "equipped with," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this disclosure based on the specific circumstances.

[0035] As shown in Figures 1-5, this disclosure proposes a green backfilling method for mineralizing CO2 from multi-source coal-based solid waste, which is based on a green backfilling system.

[0036] In this embodiment, the green filling system includes a carbon mineralization device 1, a conveyor 2, and a guide platform 3 located between the carbon mineralization device 1 and the conveyor 2 for feeding the ore conveyed by the conveyor 2 into the carbon mineralization device 1. Vertical baffles are fixedly connected to both sides of the upper surface of the guide platform 3 to prevent the ore from slipping out. The guide platform 3 can also rotate and tilt vertically.

[0037] Furthermore, an automatic pumping mechanism 4 is located below the guide platform 3. The automatic pumping mechanism 4 pumps the coolant by means of the vertical rotation of the guide platform 3. The automatic pumping mechanism 4 includes a pump cylinder 41 and a rotating seat 42, which are fixedly connected to an external fixing component. The external fixing component is not shown in the figure and may be other fixing equipment or a fixing frame, etc. The rotating seat 42 is rotatably connected to one end of the guide platform 3 via a rotating shaft. A piston column 43 is vertically slidably connected inside the pump cylinder 41. The upper part of the piston column 43 is horizontally slidably sleeved with the bottom through hole of the piston column connecting shaft 44 through an inverted U-shaped fixing connector. The top end of the piston column connecting shaft 44 is rotatably connected to the fixing seat 45 fixed to the bottom of the guide platform 3 via a horizontal rotating shaft. A fixing ring plate 46 is fixedly connected to the outer wall of the pump cylinder 41. A return spring 47 is movably sleeved on the top end of the pump cylinder 41, and the bottom end of the return spring 47 is fixedly connected to the upper surface of the fixing ring plate 46. The top end of the return spring 47 is fixedly connected to the lower surface of the guide platform 3. When the ore is conveyed by the conveyor 2 and falls onto the guide platform 3, the guide platform 3 tilts downward under pressure, which not only facilitates the ore to slide into the carbon mineralization device 1, but also causes the piston column 43 to move downward through the fixed seat 45 and the piston column connecting shaft 44, thereby pumping out the coolant in the pump cylinder 41 and circulating it through the flow pipe 6.

[0038] Furthermore, it includes a coolant storage tank 5 and a flow pipe 6. The coolant storage tank 5 is placed on flat ground or fixed externally. The flow pipe 6 connects the automatic pumping mechanism 4 and the coolant storage tank 5, utilizing the pumping capacity of the automatic pumping mechanism 4 to deliver coolant to various filling devices for cooling. The flow pipe 6 includes a first flow pipe 61, a second flow pipe 62, a heat absorption pipe 63, and a third flow pipe 64. One end of the first flow pipe 61 is connected to the outlet of the coolant storage tank 5, and the other end of the first flow pipe 61 is connected to the outlet of the pump cylinder 41 via a three-way connector. One end of the second flow pipe 62 is connected to the outlet of the pump cylinder 41 via a three-way connector and is equipped with a one-way valve to prevent liquid in the second flow pipe 62 from flowing back into the pump cylinder 41. The other end of the second flow pipe 62 is connected to the inlet end of the heat absorption pipe 63. The heat absorption pipe 63 shown in the figure is only a structural form for reference. In actual applications, it can be in various forms such as a serpentine pipe or a flexible hose. Its purpose is to dissipate heat by carrying away heat from the heating components of each filling device. A pipe is installed at the heating component of each filling device, and the pipe is connected to the heat absorption pipe 63 through a valve. During filling, only the valve of the operating device needs to be opened. The outlet end of the heat absorption pipe 63 is connected to the inlet end of the third flow pipe 64. The third flow pipe 64 includes third flow pipe a641, third flow pipe b642, and third flow pipe c643. The outlet of third flow pipe c643 is connected to the inlet of coolant storage tank 5, and the inlet of third flow pipe c643 is connected to the bottom outlet of turbine housing 7. The top inlet of automatic pumping mechanism 4 is connected to the outlet of third flow pipe b642. The inlet of third flow pipe b642 is connected to the outlet of accumulator tank 8 and is equipped with a spring valve. When the pressure inside accumulator tank 8 increases to exceed the spring force, the valve is forced to open. The inlet of accumulator tank 8 is connected to the outlet of third flow pipe a641 and is equipped with a one-way valve to prevent liquid in accumulator tank 8 from flowing back into third flow pipe a641. Coolant is transported through flow pipe 6 to various filling equipment for heat absorption and cooling, then to collection box 8 for energy accumulation and heat exchange, and finally to vortex box 7 to use the potential energy generated by collection box 8 to drive rotation and loosen the ore material to prevent blockage.

[0039] Furthermore, the device includes a vortex box 7, which is fixedly connected to an external fixing component (not shown in the figure), which could be other fixing equipment or a mounting frame. The vortex box 7 is rotatably connected to a loosening shaft 71 via bearings. The bottom end of the loosening shaft 71 extends into the interior of the carbon mineralization device 1 and is connected to stirring blades (not shown in the figure). The rotation of the stirring blades loosens the mineral material and prevents clogging. A vortex blade 72 is fixedly connected to the top end of the loosening shaft 71. The vortex blade 72 is located inside the vortex box 7. The liquid flowing from the third flow pipe b642 impacts the vortex blade 72, causing it to rotate, which in turn drives the loosening shaft 71 to rotate. Due to the energy storage design of the accumulator box 8, the vortex blade 72 is not constantly impacted by the water flow. Therefore, the loosening shaft 71 rotates periodically to loosen the material, avoiding prolonged rotation that could increase wear and other losses.

[0040] Furthermore, it includes a collection box 8, which is connected to a vortex box 7 via a flow pipe 6, to accumulate water to impact the vortex 72 and drive the rotation of the loosening shaft 71. The collection box 8 is equipped with a floating plate 81 that can float up and down. A connecting rod 82 is fixedly connected to the bottom of the floating plate 81. A spherical rod head 821 is fixedly connected to the bottom end of the connecting rod 82. A fixing strip 31 is fixedly connected to the outer wall of the guide platform 3. The fixing strip 31 has a slotted groove that allows the connecting rod 82 to move through but the rod head 821 cannot pass through.

[0041] In this embodiment, an exchange pipe 9 located inside the collection box 8 is also included. The two ends of the exchange pipe 9 extend from the collection box 8 and are connected to the external water supply equipment. The water transported in the exchange pipe 9 is heated by the coolant absorbed in the collection box 8 and sent into the water supply equipment for other uses, thereby realizing the exchange and recovery of heat.

[0042] In this embodiment, the green filling method for CO2 mineralization from multi-source coal-based solid waste based on the green filling system is as follows: When the ore mined from the source area is conveyed by the conveyor 2 and falls onto the guide platform 3, the guide platform 3 tilts downward under pressure, which not only facilitates the ore sliding into the carbon mineralization device 1, but also causes the piston column 43 to move downward through the fixed seat 45 and the piston column connecting shaft 44, thereby pumping out the coolant in the pump cylinder 41. The pumped coolant enters the heat absorption pipe 63 through the second flow pipe 62. The heat absorption pipe 63 is arranged at the heating component of the filling equipment to absorb the large amount of heat energy generated by the operation of the equipment. The cooled liquid after heat absorption continues to enter the collection tank 8 for temporary storage through the third flow pipe a641. During this process, its heat is carried away by the cold water flowing in the exchange pipe 9, realizing heat exchange. The cold water absorbs heat to form hot water that can be used for other purposes. As the ore falls continuously, the guide platform 3 repeatedly presses down and then rebounds via the return spring 47. During rebound, the piston column 43 moves upward, pumping the coolant from the coolant storage tank 5 into the pump cylinder 41 through the first flow pipe 61, and then pumping it out through the second flow pipe 62. This process repeats, continuously increasing the coolant capacity in the accumulation tank 8. The float 81, under buoyancy, moves upward, causing the connecting rod 82 to move upward. When the connecting rod 82 moves to the bottom of the guide platform 3 (where the rod head 821 is close to the horizontal position), another drop of ore causes the guide platform 3 to tilt downward, pushing the rod head 821 and causing the connecting rod 82 to move downward, which in turn causes the float 81 to move downward. This forces the coolant accumulated in the accumulation tank 8 into the vortex box 7 through the third flow pipe b642. The resulting water pressure impacts the vortex 72, causing the loosening shaft 71 to rotate, thus loosening the ore in the carbon mineralization device 1 and preventing blockage. Finally, the coolant in the turbine housing 7 flows back to the coolant storage tank 5 through the third flow pipe c643.

[0043] The above specific embodiments are merely several optional embodiments of this disclosure. Based on the technical solutions of this disclosure and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
