Description

Technical Field

[0001] This invention relates to the field of underground mining technology for metal and non-metal mines, specifically to a bottom water collection and cleaning system. Background Technology

[0002] During the production process, seepage water is generated in underground metal and non-metal mines. Water storage ponds are set up in the mine to collect the seepage water. The seepage water often contains a large amount of impurities, mainly mud and sand. The sedimentation of impurities at the bottom of the water storage pond will reduce the effective volume of the water storage. Therefore, it is necessary to clean the silt in the water storage pond regularly.

[0003] In related technologies, two water storage tanks are excavated beside the horizontal roadway at the bottom of the mine to collect seepage water. Each tank is equipped with a submersible pump and a water level gauge. The two tanks are used alternately, and the water from the tanks is pumped to the mine's main drainage pumping station via a drainage pipe. The operation of the submersible pump is controlled by the signal from the water level gauge. However, silt in the seepage water will accumulate at the bottom of the tanks, requiring manual cleaning after a period of time. This method is inefficient, labor-intensive, requires many operators, and is wasteful of manpower and resources. Summary of the Invention

[0004] This invention aims to at least partially solve one of the technical problems in related technologies. To this end, embodiments of this invention propose a well bottom water collection and cleaning system that enables automatic drainage and periodic unattended mud removal, resulting in high production efficiency and savings in manpower and resources.

[0005] The well bottom water collection and cleaning system of this invention includes:

[0006] Water storage tank, the water storage tank being used to collect seepage water;

[0007] A stirring device, at least a portion of which is located within the water storage tank, for stirring the water in the water storage tank;

[0008] A drainage device, wherein there are at least two drainage devices, and the at least two drainage devices are arranged at intervals along a first direction in the water storage tank, the drainage devices being used to drain seepage water from the water storage tank.

[0009] When the well bottom water collection and cleaning system of this invention is started for regular sludge removal, the stirring device is first started to stir the seepage water in the water storage tank (automatic drainage is not started) so as to stir up the sludge deposited at the bottom of the water storage tank and mix it into the seepage water. Then, at least one of the two drainage devices is opened to discharge the sludge and seepage water together from the water storage tank, thereby realizing automatic unmanned sludge removal, with high production efficiency and saving manpower and material resources.

[0010] In some embodiments, the drainage device includes:

[0011] A submersible pump, wherein the submersible pump is installed in the water storage tank;

[0012] A drainage branch pipe, one end of which is connected to the submersible pump, and the other end of which is located outside the water storage tank. The submersible pump is used to pump seepage water from the water storage tank into the drainage branch pipe.

[0013] A valve assembly disposed on the drain branch pipe for opening or closing the drain branch pipe.

[0014] In some embodiments, the valve assembly includes a first valve and a second valve, the first valve and the second valve being disposed on the drain branch pipe and located outside the water storage tank, the second valve being disposed adjacent to the submersible pump, the first valve being used to control the opening and closing of the drain branch pipe, and the second valve being used to prevent water in the drain branch pipe from flowing back into the water storage tank.

[0015] In some embodiments, the well bottom water collection and cleaning system further includes a water level gauge, which is installed in the water storage tank and extends vertically, the vertical direction being orthogonal to the first direction. The water storage tank has a first water level and a second water level, the first water level being higher than the second water level. When the seepage water in the water storage tank rises to the first water level, the water level gauge sends a first signal, and the submersible pump is turned on to discharge the seepage water in the water storage tank. When the seepage water in the water storage tank drops to the second water level, the water level gauge sends a second signal, and the submersible pump is turned off to stop the drainage.

[0016] In some embodiments, the water level gauge is equipped with a float that floats on the surface of the water seeping into the water storage tank.

[0017] In some embodiments, the well bottom water collection and cleaning system further includes electrical equipment for supplying power to the submersible pump and the first valve. The electrical equipment is electrically connected to the water level gauge and can receive signals from the water level gauge and control the start and stop of the submersible pump and the opening and closing of the first valve.

[0018] In some embodiments, there are at least two stirring devices, and the at least two stirring devices are arranged at intervals along the first direction, the stirring devices comprising:

[0019] Drive components;

[0020] A stirring element is disposed at the bottom of the water storage tank, and the driving element drives the stirring element to stir up the sediment in the water storage tank;

[0021] A stirring shaft, one end of which is located inside the water storage tank and connected to the stirring element, and the other end of which extends along a second direction and is located outside the water storage tank and connected to the driving element, wherein the second direction is orthogonal to the first direction, and the driving element drives the stirring shaft to rotate around the second direction so as to drive the stirring element to rotate around the second direction.

[0022] In some embodiments, the well bottom water collection and cleaning system further includes a water seal pool, which is connected to the water storage pool and the connection point is located at the top of the water storage pool, so that the clean water in the water storage pool can flow into the water seal pool.

[0023] In some embodiments, the well bottom water collection and cleaning system further includes a water seal component disposed between the stirring shaft and the water storage tank and surrounding the outer circumferential surface of the stirring shaft, so that water in the water storage tank does not easily overflow from the gap between the stirring shaft and the water storage tank. The water seal component has a water seal space that extends circumferentially along the stirring shaft and communicates with the water seal tank so that water in the water seal tank flows into the water seal space.

[0024] In some embodiments, the well bottom water collection and cleaning system further includes a drainage main pipe, one end of which is connected to the other end of the drainage branch pipe, and the other end of which is adapted to be connected to the outside. Attached Figure Description

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figure 1-2As shown, the well bottom water collection and cleaning system of this embodiment includes a water storage tank 1, a stirring device 2, and a drainage device 3. The water storage tank 1 is used to collect seepage water. Specifically, there is only one water storage tank 1. When the seepage water in the water storage tank 1 is being removed, the seepage water at the bottom of the well can still flow into the water storage tank 1. Therefore, compared with the related technology that sets two water storage tanks 1, it not only reduces the workload of workers digging the chamber and saves manpower and resources, but also shortens the construction period and speeds up the construction speed.

[0030] At least a portion of the stirring device 2 is located within the water storage tank 1 to stir the water within the tank 1. At least two drainage devices 3 are arranged at intervals along a first direction within the water storage tank 1, and the drainage devices 3 are used to drain seepage water from the water storage tank 1. Specifically, there are two drainage devices 3, arranged at intervals along the first direction.

[0031] When the well bottom water collection and cleaning system of this embodiment starts periodic sludge removal, the stirring device 2 is first started to stir the seepage water in the water storage tank 1 (automatic drainage is not started) so as to stir up the sludge deposited at the bottom of the water storage tank 1 and mix it into the seepage water. Then, at least one of the at least two drainage devices 3 is opened to discharge the sludge and seepage water together from the water storage tank 1, thereby realizing automatic unmanned sludge removal, high production efficiency, and saving manpower and material resources.

[0032] In some embodiments, the drainage device 3 includes a submersible pump 31, a drainage branch pipe 32, and a valve assembly 33. The submersible pump 31 is located inside the water storage tank 1. Specifically, the top of the underground water storage tank 1 has a structural beam 11, the submersible pump 31 is suspended on the structural beam 11, and the submersible pump 31 is located at the bottom of the water storage tank 1.

[0033] One end of the drainage branch pipe 32 (e.g.) Figure 1 The lower end of the drainage branch pipe 32 shown is connected to the submersible pump 31, and the other end of the drainage branch pipe 32 (as shown) is connected to the submersible pump 31. Figure 1 The upper end of the drainage branch pipe 32 shown is located outside the water storage tank 1. The submersible pump 31 is used to pump the seepage water in the water storage tank 1 into the drainage branch pipe 32. The valve assembly 33 is provided on the drainage branch pipe 32 for opening or closing the drainage branch pipe 32.

[0034] Specifically, when removing seepage water from the water storage tank 1, the submersible pump 31 is turned on and the valve assembly 33 is opened to connect the submersible pump 31 and the drainage branch pipe 32. This allows the submersible pump 31 to pump all the seepage water from the water storage tank 1 into the drainage branch pipe 32, facilitating subsequent unified treatment of the water in the water storage tank 1. The submersible pump 31, drainage branch pipe 32, and valve assembly 33 of at least one of the two drainage devices 3 operate simultaneously, effectively improving the working efficiency of the well bottom water collection and cleaning system of this embodiment.

[0035] In some embodiments, the valve assembly 33 includes a first valve 331 and a second valve 332. The first valve 331 and the second valve 332 are disposed on the drain branch pipe 32 and located outside the water storage tank 1. The second valve 332 is disposed adjacent to the submersible pump 31. The first valve 331 is used to control the opening and closing of the drain branch pipe 32, and the second valve 332 is used to prevent water in the drain branch pipe 32 from flowing back into the water storage tank 1.

[0036] Specifically, the first valve 331 is an electric gate valve, used to control the opening and closing of the drainage branch pipe 32, thereby controlling the connection between the drainage branch pipe 32 and the submersible pump 31. The second valve 332 is a check valve. When the submersible pump 31 stops working, it no longer discharges pressurized water, and the water in the upper end of the drainage branch pipe 32 and the pipe connected to the upper end of the drainage branch pipe 32 will flow back. The setting of the second valve 332 makes it difficult for the water in the pipe to flow back into the water storage tank 1 through the second valve 332.

[0037] In some embodiments, the well bottom water collection and cleaning system further includes a water level gauge 4, which is suspended in the water storage tank 1 by a structural beam 11 and extends vertically, with the vertical direction orthogonal to the first direction. The water storage tank 1 has a first water level and a second water level, with the first water level being higher than the second water level. When the seepage water in the water storage tank 1 rises to the first water level, the water level gauge 4 sends a signal, and the submersible pump 31 starts to discharge the seepage water in the water storage tank 1. When the seepage water in the water storage tank 1 drops to the second water level, the water level gauge 4 sends a signal, and the submersible pump 31 stops to stop the drainage. Thus, automatic drainage of seepage water in the water storage tank 1 is achieved, saving manpower and material resources.

[0038] In some embodiments, the water level gauge 4 is equipped with a float 41, which floats on the surface of the seepage water in the storage tank 1. When the float 41 rises to the first water level, the water level gauge 4 sends a first signal, activating the submersible pump 31 to clear the seepage water in the storage tank 1, causing the water level in the storage tank 1 to drop. As the water level drops, the float 41 moves up and down. When the float 41 drops to the second water level, the water level gauge 4 sends a second signal, at which point the submersible pump 31 stops to stop drainage. Thus, the float 41 makes it more convenient and intuitive for people to observe the water level of the seepage water in the storage tank 1 by observing the position of the float 41.

[0039] In some embodiments, the well bottom water collection and cleaning system further includes an electrical device 5, which supplies power to the submersible pump 31 and the first valve 331. The electrical device 5 is electrically connected to the water level gauge 4 and can receive signals from the water level gauge 4 and control the start and stop of the submersible pump 31 and the opening and closing of the first valve 331.

[0040] Specifically, when the float 41 rises to the first water level, the level gauge 4 sends a first signal, which is received by the electrical equipment 5. The electrical equipment 5 supplies power and controls the submersible pump 31 and the first valve 331 to start the submersible pump 31 and open the first valve 331, connecting the submersible pump 31 to the drainage branch pipe 32 and pumping the seepage water in the storage tank 1 into the drainage branch pipe 32. As the submersible pump 31 operates, the water level in the storage tank 1 gradually decreases until the float 41 drops to the second water level. At this point, the level gauge 4 sends a second signal, which is received by the electrical equipment 5. The electrical equipment 5 then stops supplying power to the submersible pump 31 and controlling the first valve 331, causing the submersible pump 31 to stop operating and the first valve 331 to close. During this process, the seepage water at the bottom of the well continuously flows into the storage tank 1 and accumulates there. When the water level rises again to the first water level, the above drainage process is repeated. Thus, the well bottom water collection and cleaning system of this embodiment can not only achieve automatic drainage of seepage water in the storage tank 1, but also achieve periodic unattended sludge removal, resulting in high work efficiency.

[0041] In some embodiments, there are at least two agitators 2, and the at least two agitators 2 are arranged at intervals along a first direction. Specifically, there are two agitators 2, and the two agitators 2 are arranged at intervals along the first direction. When cleaning the silt at the bottom of the water storage tank 1, the two agitators 2 are started first to stir up the silt at the bottom of the water storage tank 1 and mix it into the seepage water. The arrangement of the two agitators 2 effectively improves the stirring efficiency and greatly reduces the silt at the bottom of the water storage tank 1.

[0042] The stirring device 2 includes a drive unit 21, a stirring element 22, and a stirring shaft 23. The stirring element 22 is located at the bottom of the water storage tank 1, and the drive unit 21 drives the stirring element 22 to agitate the sediment in the water storage tank 1. One end of the stirring shaft 23 (e.g., Figure 1 The left end of the stirring shaft 23 shown is located in the water storage tank 1 and connected to the stirring element 22. The other end of the stirring shaft 23 (as shown) Figure 1 The right end of the stirring shaft 23 shown extends along the second direction and is located outside the water storage tank 1 and connected to the drive member 21. The second direction is orthogonal to the first direction. The drive member 21 drives the stirring shaft 23 to rotate around the second direction so as to drive the stirring member 22 to rotate around the second direction.

[0043] Specifically, the agitator 22 is located at the bottom of the water storage tank 1, making it easier to stir up the sludge at the bottom of the water storage tank 1, thereby improving the stirring efficiency of the agitator 2. The agitator shaft 23 is driven to rotate in the second direction by the drive component 21, which in turn drives the agitator 22 to rotate in the second direction, making the working principle of the agitator 2 simple and easy to operate.

[0044] In some embodiments, the well bottom water collection and cleaning system further includes a water seal pool 6, which is connected to the water storage pool 1 and the connection point is located at the top of the water storage pool 1 so that the clean water in the water storage pool 1 can flow into the water seal pool 6.

[0045] Specifically, the well bottom water collection and cleaning system also includes a connecting pipe (not shown), which is located between the water seal pool 6 and the water storage pool 1, and is located at the upper end of the water storage pool 1 and away from the seepage inflow point. The seepage water in the mine often contains silt and is sewage. The sewage flows into the underground water storage pool 1, where it gradually settles and becomes clear. The clarified water flows into the water seal pool 6 through the connecting pipe for reuse.

[0046] In some embodiments, the well bottom water collection and cleaning system further includes a water seal (not shown), which is disposed between the stirring shaft 23 and the water storage tank 1 and is arranged around the outer peripheral surface of the stirring shaft 23 so that the water in the water storage tank 1 does not easily overflow from the gap between the stirring shaft 23 and the water storage tank 1. The water seal has a water seal space (not shown) that extends circumferentially along the stirring shaft 23 and communicates with the water seal tank 6 so that the water in the water seal tank 6 flows into the water seal space.

[0047] Specifically, the water storage tank 1 has a perforation 12 on its peripheral wall, the stirring shaft 23 is inserted through the perforation 12, the water seal is disposed in the perforation 12 and is arranged around the outer peripheral surface of the stirring shaft 23, the inner peripheral surface of the water seal is in close contact with the outer peripheral surface of the stirring shaft 23, and the outer peripheral surface of the water seal is in close contact with the inner peripheral surface of the perforation 12.

[0048] Each of the two stirring devices 2 is equipped with a water seal (not shown), and the water seals of the two stirring devices 2 are connected, with each water seal having a water seal space. The water seal tank 6 has an outlet pipe (not shown) that connects the water seal and the water seal tank 6, allowing the clean water in the water seal tank 6 to serve as the water source for the water seal and flow into the two water seals through the outlet pipe. This allows the clean water in the water seal tank 6 to flow into the two water seal spaces to form a water seal, thereby preventing seepage water in the water storage tank 1 from easily overflowing from the gap between the perforation 12 and the stirring shaft 23.

[0049] In some embodiments, the well bottom water collection and cleaning system further includes a drainage main pipe 7, one end of which is connected to the other end of a drainage branch pipe 32, and the other end of the drainage main pipe 7 is adapted to be connected to the outside.

[0050] Specifically, the main drainage pipe 7 is suitable for installation on a bracket fixed to the side wall of the tunnel chamber, and the other end of the main drainage pipe 7 is laid to the main drainage pump room of the mine so as to collect and treat the seepage water in the water storage tank 1 in a unified manner.
