Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of stope drainage, and particularly relates to a drainage device for a mined - out area filled with materials in a mine. Background Art
[0002] After the ore extraction in an underground mine is completed, a mined - out area with a certain volume will be formed. Due to the lack of support, the mined - out area has the risk of collapse, which will threaten the ore extraction in adjacent stopes and pose a hidden danger to the safe production of the mine. Currently, the mined - out area is usually disposed of by the filling method. Tailings, cement and other materials are prepared into filling slurry, and then transported into the mined - out area.
[0003] During filling, it is necessary to drain the excess water in the filling slurry to promote the consolidation and hardening of the slurry. However, in the process of draining water by the existing drainage devices, some fine cement slurries will be pumped into the drainage pipes. After the drainage operation stops, it is impossible to clean them in time, resulting in the hardening of the cement slurries and blocking the pipes. Summary of the Utility Model
[0004] The utility model aims at the problems in the prior art and proposes the following technical solutions:
[0005] A drainage device for a mined - out area filled with materials in a mine, including a slurry pipe and a drainage pipe. An anti - blocking mechanism is installed at the water - pumping end of the drainage pipe. One end of the slurry pipe is fixedly connected to an elbow pipe and a connecting pipe through a first three - way joint, and the other end is communicated with a feeding device. The drainage end of the drainage pipe is communicated with the connecting pipe through a second three - way joint. And a water - suction pipe is fixedly connected to the end of the second three - way joint far away from the connecting pipe and the drainage pipe. The end of the water - suction pipe far away from the second three - way joint is communicated with a water pump. First valves and second valves are respectively installed at the ends of the first three - way joint and the second three - way joint close to the connecting pipe.
[0006] As a preference of the above technical solution, the anti - blocking mechanism includes a filter box. The water - pumping end of the drainage pipe is fixedly sleeved in the inner ring on one side of the filter box. A cleaning component for cleaning the filter holes is installed inside the filter box, and a transmission component for driving the cleaning component is installed at the drainage end of the drainage pipe.
[0007] As a preference of the above technical solution, the cleaning component includes a bearing fixedly sleeved on the outer circle of the drainage pipe. A rotating arm is fixedly connected to the outer wall of the bearing. A cleaning brush is fixedly connected to the end of the rotating arm far away from the bearing, and the cleaning brush is attached to the inner wall of the filter box.
[0008] As a preference of the above technical solution, the transmission component includes a transmission shaft rotatably connected to the drainage pipe. One end of the transmission shaft located inside the drainage pipe is fixedly connected with an impeller, and the end located outside the drainage pipe is fixedly connected with a gear.
[0009] Preferably, as the above technical solution, one side of the rotating arm is fixedly connected with a support rod, and one end of the support rod away from the rotating arm is fixedly connected with a toothed ring, and the toothed ring is in meshing transmission with the gear.
[0010] The beneficial effects of the present utility model are as follows:
[0011] 1. After the slurry pipe and the elbow pipe of the present utility model stop transporting the filling slurry, during the process of flushing the slurry pipe and the elbow pipe with water, by opening the first valve and the second valve of the first three-way joint and the second three-way joint, the inner walls of the water suction pipe and the drain pipe can be cleaned simultaneously, preventing the cement slurry from coagulating and blocking inside and keeping the pipeline unobstructed.

[0016] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions of the present utility model will be clearly and completely described below in conjunction with the embodiments.
[0017] Embodiment 1
[0018] As Figure 1 shown, the mine filling stope drainage device includes a feeding device, a water pump, a slurry pipe 1 and a drain pipe 7. An anti-blocking mechanism is installed at the water suction end of the drain pipe 7. One end of the slurry pipe 1 is fixedly connected with an elbow pipe 3 and a connecting pipe 4 through a first three-way joint 2, and the other end is communicated with the feeding device. The drainage end of the drain pipe 7 is communicated with the connecting pipe 4 through a second three-way joint 5. And one end of the second three-way joint 5 away from the connecting pipe 4 and the drain pipe 7 is fixedly connected with a water suction pipe 6, and the end of the water suction pipe 6 away from the second three-way joint 5 is communicated with the water pump. The first three-way joint 2 and the second three-way joint 5 are respectively provided with a first valve and a second valve near the connecting pipe 4.
[0019] Specifically, the feeding device, the slurry pipe 1, the water suction pipe 6 and the water pump are all detachably connected. After stopping the slurry transportation, the feeding device is separated from the slurry pipe 1, and the water suction pipe 6 is separated from the water pump and connected to the slurry pipe 1 to convey clean water to the slurry pipe 1, so as to clean the inner walls of the slurry pipe 1, the first three-way joint 2 and the elbow pipe 3. At the same time, the first valve and the second valve of the first three-way joint 2 and the second three-way joint 5 are opened, so that the clean water can flow into the water suction pipe 6 and the drain pipe 7 to wash and clean the fine slurry adhering to the inner wall, prevent condensation, and ensure the smoothness of the slurry pipe 1, the first three-way joint 2, the elbow pipe 3, the connecting pipe 4, the second three-way joint 5, the water suction pipe 6 and the drain pipe 7.
[0020] As Figure 1 and Figure 2 shown, the anti-blocking mechanism includes a filter box 8. The water suction end of the drain pipe 7 is fixedly sleeved in the inner ring on one side of the filter box 8. A cleaning component for cleaning the filter holes is installed inside the filter box 8, and a transmission component for driving the cleaning component is installed at the water discharge end of the drain pipe 7.
[0021] Specifically, when the slurry pipe 1, the first three-way joint 2, and the elbow pipe 3 are conveying the filling slurry, and during the drainage process of the water suction pipe 6, the second three-way joint 5, and the drain pipe 7, the first valve and the second valve of the first three-way joint 2 and the second three-way joint 5 are in the closed state, so that the slurry conveyed by the slurry pipe 1, the first three-way joint 2, and the elbow pipe 3 will not enter the water suction pipe 6, the second three-way joint 5, and the drain pipe 7. During the drainage process of the water suction pipe 6, the second three-way joint 5, and the drain pipe 7, most of the filling slurry can be filtered through the filter box 8. During the water pumping or cleaning process of the drain pipe 7, the transmission component can be driven to operate, and the transmission component drives the cleaning component to clean the filter holes of the filter box 8 to prevent the filter holes from being blocked and affecting the drainage efficiency.
[0022] Embodiment 2
[0023] As Figure 1 and Figure 2 shown, for the mine filling stope drainage device, compared with the first embodiment, the cleaning component in this embodiment includes a bearing 12 fixedly sleeved on the outer ring of the drain pipe 7. The outer wall of the bearing 12 is fixedly connected with a rotating arm 13. One end of the rotating arm 13 away from the bearing 12 is fixedly connected with a cleaning brush 14, and the cleaning brush 14 is attached to the inner wall of the filter box 8.
[0024] It should be noted that the centers of the drain pipe 7 and the filter box 8 are located on the same axis. The number of the rotating arms 13 is at least two. When the cleaning brush 14 rotates around the drain pipe 7 as the axis, the cleaning brush 14 will always be attached to the inner wall of the filter box 8, so that the foreign matters attached to the filter holes of the filter box 8 can be cleaned off.
[0025] As Figure 2As shown in the figure, the transmission assembly includes a transmission shaft 9 rotatably connected to the drain pipe 7. One end of the transmission shaft 9 located inside the drain pipe 7 is fixedly connected to an impeller 10, and one end located outside the drain pipe 7 is fixedly connected to a gear 11.
[0026] Specifically, when the drain pipe 7 is pumping water or filling clean water, the flowing water will push the impeller 10 to drive the transmission shaft 9 to rotate, and the rotation of the transmission shaft 9 will further drive the gear 11 located outside the drain pipe 7 to rotate.
[0027] As Figure 2 shown in the figure, one side of the rotating arm 13 is fixedly connected to a support rod 15. One end of the support rod 15 away from the rotating arm 13 is fixedly connected to a toothed ring 16, and the toothed ring 16 is in meshing transmission with the gear 11.
[0028] Specifically, the toothed ring 16 is concentric with the filter box 8 and the bearing 12, so that when the gear 11 rotates, it will drive the rotating arm 13 and the cleaning brush 14 to rotate synchronously through meshing with the toothed ring 16, thereby being able to clean the filter box 8.
[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than limiting it.
