Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water ecological pollution treatment, and particularly relates to a water ecological pollution treatment device and method for an open-pit mine. BACKGROUND

[0002] In the process of open-pit mining, the oxidation of sulfide minerals (such as pyrite) and the dissolution of heavy metals can easily lead to the water body in the mining area being acidic and rich in heavy metal ions such as iron, manganese and copper, forming a typical water ecological pollution problem. Such sewage is gathered in the pit concave land formed by mining through surface runoff or underground seepage, and gradually forms a closed or semi-closed pit lake.

[0003] At present, the control of pit lake water pollution mainly adopts the strategy of "front-end interception + end treatment", that is, the sewage is pretreated at the entrance of the pit lake, including adjusting the pH by adding alkaline agents such as lime and calcium carbonate, removing heavy metals by chemical precipitation, adsorption and other methods, and then discharging the treated water into the lake and assisting with ecological restoration. However, although the sewage is pretreated at the entrance of the pit lake, the water in the pit lake still has irregular local acidity abnormalities. The reasons include: (1) A large amount of acidic substances may accumulate in the pit lake sediment, which will be released into the water body under certain environmental conditions (such as temperature change, water flow disturbance, etc.); (2) Rainfall runoff inputs acidic pollutants that have not been completely intercepted. At present, there is a lack of cruise monitoring means for the water body in the pit lake, which cannot timely find the areas of abnormal acidity in the pit lake, and there is also no effective point treatment measure to target the water body in these abnormal areas for targeted adjustment and treatment, so that the water ecological pollution treatment effect of the open-pit mine is limited, and it is difficult to achieve the ideal treatment quality.

DETAILED DESCRIPTION

[0033] The following detailed description of the application is made in connection with the accompanying drawings. It is necessary to point out here that the following detailed description is only used to further illustrate the application, and cannot be understood as limiting the scope of protection of the application. Those skilled in the art can make some non-essential improvements and adjustments to the application based on the above application content.

[0034] Please refer to Figure 1 A water ecological pollution treatment device for open-pit mines, comprising a carrier 1 floating in a pit lake and capable of walking and cruising according to a set route, a monitoring assembly 3 for monitoring the pH value of the water in different depth regions arranged on the carrier 1, a pumping assembly for pumping the water in the pH value abnormal region, and a treatment assembly 5 for neutralizing and adjusting the pumped abnormal water. The water inlet length of the monitoring assembly 3 can be adaptively adjusted according to the actual water depth at the position of the treatment device, so that the distance between the lower end of the monitoring assembly 3 and the lake bottom is always kept at a set distance.

[0035] It should be noted that: the platform 1 is similar to a floating island, and its bottom is equipped with several sets of propeller propulsion mechanisms to provide propulsion power for the treatment device to travel and cruise; the treatment device uses satellite positioning technology to travel and cruise along a set route, and can correct the route when it deviates from the route by adjusting the propulsion direction and thrust of several sets of propeller propulsion mechanisms. The above is existing technology, and the specific hardware and software composition, connection and logical relationship to achieve the above functions will not be described in detail here; in addition, an appropriate number of the treatment devices can be set according to the size of the mining pit lake (the larger the area, the more treatment devices should be set) to modularly handle different areas, so as to avoid the treatment device taking too long to complete a full cruise, which would prevent the timely detection and treatment of regional water pH abnormalities.

[0036] The treatment device travels and cruises in the mine pit lake along a set route. The submersion length of the monitoring component 3 is adaptively adjusted according to the actual water depth at the location of the pollution treatment device, ensuring that the lower end of the monitoring component 3 always maintains a set distance from the lake bottom. The monitoring component 3 monitors the pH value of the water in different depth zones (i.e., different depth zones are separated by a fixed distance from the lake bottom, such as the -2 meter zone, the 2-4 meter zone, and the 4-6 meter zone). When an abnormal pH value is detected, the treatment device stops traveling and maintains its current position (several sets of propeller propulsion mechanisms adaptively adjust and combine with satellite positioning to avoid position deviation due to water flow and wind). The water in the area with abnormal pH value is pumped out by the pumping component, neutralized and regulated by the treatment component 5, and then discharged. By circulating and monitoring the pH value of the water in the mine pit lake in different depth zones, it can promptly detect water areas with abnormal pH values ​​in the mine pit lake and carry out regional targeted treatment, effectively solving the problem of regional abnormal pH values ​​in the water in the mine pit lake and ensuring the effect and quality of water ecological pollution treatment in open-pit mines.

[0037] Furthermore, the platform 1 is also equipped with a radar probe 9 (above the surface of the mine lake) for obstacle detection in the forward direction of the treatment device and a sonar probe 10 for obstacle detection in the vertical direction of the water body. The sonar probe 10 is also used to detect water depth. The lower end of the monitoring component 3 is equipped with a water depth sensor 4 for feedback of the water depth of the monitoring component 3. When the radar probe 9 detects an obstacle in front, the treatment device turns to avoid it and then automatically returns to the set route. When the sonar probe 10 detects an underwater obstacle (such as a reef), the water depth of the monitoring component 3 is shortened so that it can cross the underwater obstacle. The water depth at the location of the treatment device is detected in real time by the sonar probe 10. Correspondingly, the water depth of the monitoring component 3 is adaptively adjusted so that the lower end of the monitoring component 3 always maintains a set distance from the lake bottom.

[0038] Please see Figure 1In one embodiment of the present invention, the monitoring component 3 includes a vertically arranged water inlet and a plurality of pH sensors 301 equidistantly arranged from top to bottom on the water inlet for monitoring the pH value of the water. The pumping component includes a pump set 201. The water inlet is composed of pipes 202, the number of which is the same as the number of pH sensors 301, and whose ends are sequentially rotatably connected. The plurality of pipes 202 are sequentially connected, and the lowermost pipe 202 is closed at its lower end. The pH sensors 301 are correspondingly arranged on the pipes. On the pipe fitting 202, there are several blades 203 arranged from top to bottom to create vortices in the water when the pipe fitting 202 rotates. The pipe fitting 202 is also evenly distributed with openable and closable inlets 204. A solenoid valve is provided at each inlet 204. Except for the uppermost pipe fitting 202, each of the other pipe fittings 202 has a baffle plate 205 at its upper end to separate the water in the vertical direction. The suction end of the pump set 201 is connected to multiple pipe fittings 202.

[0039] In this embodiment, under normal circumstances, the inlet 204 on each pipe fitting 202 is in a closed state (i.e., the solenoid valve is in a closed state). When an abnormal pH value is detected in the water (such as in the 2-4 meter area or the 6-8 meter area), the corresponding pipe fitting 202 rotates and the inlet 204 on the corresponding pipe fitting 202 opens. At the same time, the pump group 2 starts. When the pipe fitting 202 rotates, it drives the corresponding impeller 203 to rotate, thereby generating an underwater vortex. Utilizing the characteristic of the water flowing inward from the outer ring of the vortex (in the horizontal direction), coupled with the blocking effect of the baffle plate 205 (in the vertical direction), the water with abnormal pH value will not spread outward. Abnormal water is confined to the area formed by the corresponding pipe fitting 202 (height) and the two baffles 205 above and below the pipe fitting 202. The abnormal water enters the pipe fitting 202 through the inlet 204 and is pumped out by the pump unit 2 for further treatment. When the corresponding pH sensor 301 detects that the pH value of the water is normal and remains so for a certain period of time (such as 30s, 1min, etc.), it means that the abnormal water has been completely pumped out. It should be noted that when the water in the water surface area is abnormal, but the corresponding pipe fitting 202 is not completely submerged in water, only the inlet 204 in the water is open, and the other inlets 204 are closed.

[0040] Based on the previous embodiment, please refer to Figure 2In one embodiment of the present invention, the water-blocking plate 205 includes a hollow first plate 2051 and a second plate 2052 rotatably disposed in the first plate 2051 and coaxial with the first plate 2051. The pipe 202 is provided with multiple first through grooves 2053 circumferentially. The second plate 2052 is provided with second through grooves 2054 circumferentially with the same outline as the first through grooves 2053 and corresponding to them one by one. The interior of the first plate 2051 and the second plate 2052 are in a sealed fit contact (e.g., a rubber sheet can be provided between the contact surfaces of the first plate 2051 and the second plate 2052) to prevent water from entering the interior of the first plate 2051.

[0041] A torsion spring 2057 is provided at the rotatable connection between the second plate 2052 and the first plate 2051. In its natural state, the first through groove 2053 and the second through groove 2054 are in a fitting state. A magnetic element 2055 is provided on the second plate 2052. An electromagnet 2056 is provided in the first plate 2051 to magnetically attract the magnetic element 2055 and drive the second plate 2052 to rotate at a certain angle, so that the first through groove 2053 and the second through groove 2054 are completely misaligned.

[0042] In this embodiment, during normal operation and cruising, the first channel 2053 and the second channel 2054 are in a fitted state, so that the multiple first channels 2053 on the baffle plate 205 are in a through state, thereby reducing the water resistance (up and down direction) encountered by the monitoring component 3 when adjusting the water inlet length, and reducing the shaking amplitude of the treatment device when the water inlet length of the monitoring component 3 is adjusted; when an abnormal pH value of the water is detected, the baffle plate 205 at the upper and lower positions of the corresponding pipe 202 is converted to a closed state, specifically: the electromagnet 2056 is powered by the electromagnetic attraction of the magnetic component 2055, thereby driving the second plate 2052 to rotate at a certain angle, so that the first channel 2053 and the second channel 2054 are completely misaligned.

[0043] Please see Figure 1 In one embodiment of the present invention, the treatment device further includes an adjusting component 6 for adjusting the water inlet length of the monitoring component 3. The adjusting component 6 includes a first frame 601 mounted on the platform 1, a support seat 602 slidably mounted on the first frame 601 (by means of setting a slide groove, slide rail, etc.), a threaded rod 603 mounted on the first frame 601, a first driving member 604 for driving the threaded rod 603 to rotate (the first driving member 604 is a servo motor, geared motor, etc. in the prior art), and a second frame 605 mounted above the platform 1. The threaded rod 603 passes through the support seat 602 by a threaded engagement. The second frame 605 is fixedly connected to the support seat 602. The monitoring component 3 is mounted on the second frame 605.

[0044] In this embodiment, the first driving component 604 drives the threaded rod 603 to rotate, thereby causing the second frame 605 to move up and down, which in turn causes the monitoring component 3 to move up and down, thus achieving the adjustment of its water entry length.

[0045] Please see Figure 1 , Figures 3-5 In one embodiment of the present invention, the treatment device further includes a drive assembly 8 for selectively driving the rotation of pipe fittings 202 in water bodies with abnormal pH values. The drive assembly 8 includes a shaft 801 mounted on a second frame 605 and a second drive component 802 for driving the shaft 801 to rotate (the second drive component 802 is a servo motor, geared motor, etc. in the prior art). A base pipe 803 is also provided on the second frame 605. The suction end of the pump group 2 is connected to the base pipe 803. The shaft 801, the base pipe 803, and multiple pipe fittings 202 are coaxial. The lower end of the base pipe 803 is rotatably connected to the upper end of the uppermost pipe fitting 202. The lower end of the shaft 801 passes through multiple pipe fittings 202 in sequence and is finally located in the lowermost pipe fitting 202. The shaft 801 and the corresponding rod segment of each pipe fitting 202 are provided with fastening components for keeping the shaft 801 and the corresponding pipe fitting 202 fixed.

[0046] The fastening assembly includes at least one telescopic member 804 disposed on the shaft 801 and an abutment member 805 disposed on the movable end of the telescopic member 804 for contacting and abutting against the inner wall of the pipe 202. The telescopic member 804 is an electric telescopic rod.

[0047] In this embodiment, when an abnormal pH value of the water is detected, the corresponding pipe fitting 202 is the driving target, and the fastening component corresponding to the driving target performs an action. Specifically, the telescopic member 804 extends to drive the contact member 805 to contact and abut against the inner wall of the pipe fitting 202, and then the second driving member 802 drives the shaft 801 to rotate, thereby driving the target pipe fitting 202 to rotate.

[0048] Please see Figure 1 and Figure 3 In one embodiment of the present invention, the processing component 5 includes a cylinder 502 connected to the discharge end of the pump group 2, a dosing component 501 for adding alkaline agents into the cylinder 502, and a stirring paddle 503 disposed in the cylinder 502. A transmission component 504 (including a transmission shaft and a transmission gear set) is provided between the stirring paddle 503 and the shaft 801. The cylinder 502 is provided with a drain outlet for discharging the treated water.

[0049] In this embodiment, the dosing component 501 is an existing device used to continuously and quantitatively add alkaline agents to the cylinder 502. It is equipped with a corresponding feedback function based on wireless communication to inform relevant personnel of the remaining alkaline agent, such as by editing a text message or sending a push notification via a mobile APP. This is existing technology and will not be elaborated or specifically limited here. When the remaining alkaline agent is insufficient, relevant personnel will replenish it. The extracted abnormal water enters the cylinder 502 and is mixed with the alkaline agent (mixed by stirring paddle 503) to carry out a neutralization reaction, thereby achieving acid-base neutralization and adjustment treatment of the water.

[0050] Please see Figure 1 , Figure 6 and Figure 7 In one embodiment of the present invention, the platform 1 is generally ring-shaped, the monitoring component 3 passes through the inner ring of the platform 1, and the platform 1 is also provided with a planting area 11 for planting aquatic plants to purify water.

[0051] The treatment device also includes a spraying assembly 7 for spraying water on the aquatic plants in the planting area 11 to clean the dust on the leaves of the aquatic plants. The spraying assembly 7 includes a first pipe 701 mounted on the second frame 605, a second pipe 702 rotatably connected to the end of the first pipe 701, and a spray pipe 703 mounted on the upper end of the second pipe 702. The second pipe 702 is connected to the spray pipe 703. Water outlet holes 704 are arranged on the spray pipe 703. The upper end of the shaft 801 extends into the second pipe 702 and is fixedly connected to the second pipe 702. The drain outlet on the cylinder 502 is connected to the first pipe 701.

[0052] In this embodiment, planting aquatic plants purifies the water. However, open-pit mines typically produce a lot of dust, which can cover the leaves of aquatic plants and affect their growth. By introducing the treated water into the spray pipe 703 and then spraying it onto the planted aquatic plants through the outlet 704, the water is effectively washed and dusted off the plant leaves, allowing the aquatic plants to grow normally. The rotation of the shaft 801 drives the spray pipe 703 to rotate, ensuring that the spraying area fully covers the planting area 11.

[0053] Furthermore, in this embodiment, the first tube 701 is also provided with a filter frame 705, which is located below the water outlet 704 and is used to filter solid substances (such as calcium sulfate, metal carbonates, etc.) produced by acid-base neutralization reaction in the water.

[0054] This invention also provides a method for treating water ecological pollution in open-pit mines, using any one of the above-described technical solutions for treating water ecological pollution in open-pit mines, comprising the following steps:

[0055] S1: The treatment device travels and cruises in the mine pit lake according to the set route. The water depth of the monitoring component 3 is adjusted according to the actual water depth at the location of the pollution treatment device. The pH value of the water body is monitored by the monitoring component 3 in the depth area.

[0056] S2: When an abnormal pH value is detected, the treatment device stops moving and maintains its current position. It pumps water from the area with abnormal pH value through the pumping component, and discharges the water after acid-base neutralization and adjustment through the treatment component 5.

[0057] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
