Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, and in particular to a pretreatment device and treatment method for old kiln water with an early warning system. Background Technology

[0002] The design and selection of the mine water treatment plant are based on the quality of the influent and effluent. Water samples are collected during normal mine production or the construction phase. These samples cannot cover the accumulated water from old mine shafts encountered during production. Compared to conventional mine water, this water is characterized by abnormal indicators in some parameters. This water enters the mine water treatment plant along with the main mine water, and the existing treatment process cannot handle the newly added or abnormal indicators, leading to effluent exceeding standards. Direct discharge of this type of water will cause serious environmental problems: low pH and high concentrations of heavy metals can poison aquatic organisms (e.g., the half-lethal concentration of Cu²⁺ for fish is only 0.1 mg / L), and after seeping into the soil, it can cause acidification and nutrient loss. Simultaneously, sulfates and heavy metals migrate through pores, polluting deep groundwater.

[0003] Common methods for treating acidic old mine water include chemical methods and ion exchange methods. Chemical methods primarily involve directly adding lime or sodium hydroxide to the water to neutralize the acidity, causing heavy metals to precipitate as hydroxides and sulfate ions to form calcium sulfate. The hydroxides and calcium sulfate then form flocculent matter and precipitates, which are scattered throughout the water. Retrieving these flocculent matter and precipitates is difficult and time-consuming, resulting in low efficiency in treating old mine water. Furthermore, the coal dust generated during coal mining encounters bedrock, mixing with bedrock fragments. These fragments are carried along with the coal dust to the mine water treatment plant, severely impacting its operation and causing the plant to operate under overload conditions while failing to meet treatment standards. Summary of the Invention

[0008] Preferably, the feeding plate includes an outer frame fixedly connected to the rotating rod and a mesh plate rotatably connected to the outer frame via a pin, wherein a torsion spring is provided on the pin for driving the mesh plate to reset and rotate.

[0009] Preferably, the arc-shaped processing shell includes an arc-shaped shell and circular plates fixed on both sides of the arc-shaped shell. The circular plates include an outer plate and an inner plate that are fixedly connected by a connecting plate, and an annular plate that is rotatably connected between the outer plate and the inner plate. The pin is rotatably connected inside the annular plate.

[0010] Preferably, the feeding assembly includes a driven gear disposed at the end of the pin shaft, and a rack frame that meshes with the driven gear is also disposed between the outer plate and the inner plate. The rack frame includes an outer rack connected to the outer plate via a connecting plate and an inner rack connected to the inner plate via a connecting plate. The outer rack and the inner rack alternately mesh with the driven gear.

[0013] Preferably, the exhaust pipe is rotatably connected to the support plate and a torsion spring is provided between them. One end of the exhaust pipe is fixedly provided with a movable gear, and a large gear ring that meshes with the movable gear is fixedly provided on the annular plate. The large gear ring is provided with several gaps.

[0014] This invention also discloses a method for pretreating old kiln water with an early warning system. The method involves applying the aforementioned old kiln water pretreatment device with an early warning system, and includes the following steps: S1: Mine water enters through the main inlet pipe. With the first valve body open and the second and third valve bodies closed, the mine water enters the mine water treatment station through the main inlet pipe. During this period, water quality monitoring sensors monitor the water quality in the main inlet pipe. When the water quality monitoring sensor detects that the acidity of the water in the main inlet pipe exceeds the standard, the first valve body is closed and the second valve body is opened, so that the water entering the main inlet pipe enters the arc-shaped treatment shell through the inlet pipe. S2: An alkaline substance is added inside the arc-shaped treatment shell to react with acidic substances in the water to form precipitates or flocculents; The drive motor is controlled to run, and the output shaft of the drive motor drives the rotating rod to rotate. The rotating rod drives the material-pulling plate to rotate inside the arc-shaped treatment shell. The material-pulling plate can move the water inside the arc-shaped treatment shell, thereby making the alkaline and acidic substances fully mixed. When the material-dispensing plate rotates, it can move the sediment or flocculent matter in the water. When the material-dispensing plate moves out of the arc-shaped shell, some of the flocculent matter and sediment will slide down along the tilted material-dispensing plate and fall into the receiving tray. S3: As the rotating rod drives the material-pulling plate to continue rotating, the driven gear on the pin meshes with the rack frame, and the screen plate rotates around the pin as the center, causing the screen plate to flip relative to the outer frame, so that the side that originally moved the sediment and flocculent matter flips down, making it easier for the sediment and flocculent matter to fall. Furthermore, when the screen plate flips downwards, the driven gear alternately meshes with the outer and inner racks on the rack frame, causing the pin to drive the screen plate to swing back and forth, and the sediment and flocculent matter on the screen plate fall quickly. S4: When the rotating rod rotates, it drives the collar to move through the eccentric rod. When the collar moves, it drives the swing rod to move. The swing rod drives the slide rod to slide back and forth axially. When the slide rod moves, it drives the receiving tray to move back and forth on the frame, so that the sediment or flocculent material falling into the receiving tray is evenly spread and the storage space in the receiving tray is guaranteed. S5: As the rotating rod drives the material-pulling plate to continue rotating, the driven gear no longer meshes with the rack frame, and the pin shaft drives the mesh plate to reset under the action of the torsion spring. When it rotates into the arc-shaped shell, it continues to dredge the sediment and flocculent matter in the water. S6: After the water in the arc-shaped treatment shell is pretreated, the second valve body is closed and the third valve body is opened. The treated water in the arc-shaped treatment shell flows back from the return pipe to the main inlet pipe and enters the mine water treatment station through the main inlet pipe. When the water quality monitoring sensor on the main inlet pipe detects that the acidity of the water is lower than the treatment standard, the second and third valves are closed and the first valve is opened, so that the water is directly transported from the main inlet pipe to the mine water treatment station.

[0015] Compared with the prior art, the present invention provides a pretreatment device and method for old kiln water with an early warning system, which has the following beneficial effects: 1. In this invention, by setting up an ingress warning component to monitor environmental parameters such as water quality in real time, the equipment is ensured to operate in the optimal working environment. This can play an early warning and forecasting role in preventing wastewater from old kilns from entering the mine water system, thus detecting the situation of old kiln wastewater entering the system in advance. At the same time, the old kiln wastewater is pretreated with alkali by using an arc-shaped treatment shell, and the sediment and flocculent material generated inside the arc-shaped treatment shell are retrieved by the retrieval component. This allows the pretreated water to enter the mine water treatment station, thereby reducing the operating load of the mine water treatment station and ensuring that the mine water can meet the treatment standards.

[0016] 2. In this invention, by controlling the operation of the drive motor, the output shaft of the drive motor drives the rotating rod to rotate. The rotating rod drives the material-dispensing plate to rotate inside the arc-shaped treatment shell. The material-dispensing plate can move the water inside the arc-shaped treatment shell, thereby making the alkaline and acidic substances fully mixed. When the material-dispensing plate rotates, it can also move the sediment or flocculent matter in the water. When the material-dispensing plate moves out of the arc-shaped shell, some flocculent matter and sediment will slide down along the inclined material-dispensing plate and fall into the receiving tray, avoiding the distribution of sediment or flocculent matter in the water, which would hinder the collision and contact between the molecules of acidic and alkaline substances, thus slowing down the neutralization reaction rate. The discharge of sediment and flocculent matter can ensure the wastewater pretreatment efficiency.

[0017] 3. In this invention, as the rotating rod drives the material-pushing plate to continue rotating, when the material-pushing plate 503 moves out of the arc-shaped housing, the driven gear on the pin shaft meshes with the rack frame, and the screen plate rotates around the pin shaft as the center, causing the screen plate to flip relative to the outer frame, so that the side that originally pushed the sediment and flocculent matter flips to face downwards, making it easier for the sediment and flocculent matter to fall and improving the cleaning effect of debris.

[0018] 4. In this invention, when the rotating rod rotates, it can drive the collar to move through the eccentric rod. When the collar moves, it drives the swing rod to move. The swing rod drives the slide rod to slide back and forth axially. When the slide rod moves, it drives the receiving tray to move back and forth on the frame, so that the sediment or flocculent material falling into the receiving tray is evenly spread, ensuring the storage space in the receiving tray. This allows the receiving tray to make the most of its internal space to store sediment or flocculent material, avoiding the accumulation of sediment or flocculent material and reducing the cleaning cycle for workers.

[0019] 5. In this invention, when the swing rod drives the slide rod to move back and forth, the piston on the slide rod moves back and forth inside the sleeve, so that the first chamber and the second chamber inside the sleeve alternately draw in and exhaust air. The exhaust air enters the exhaust pipe through the air guide pipe and the air collection pipe. The gas is sprayed onto the flipped screen through the nozzle. Since the sediment and flocculent material are located on the lower side of the screen at this time, the cleaning effect of sediment and flocculent material that are not easy to fall off the screen is further improved.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0023] In the description of this invention, it should be noted that the terms "upper," "lower," "inner," "outer," "top / bottom," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0024] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "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. For those skilled in the art, the specific meaning of the above terms in this invention can be understood according to the specific circumstances.

[0025] like Figure 1 , Figure 3 , Figure 5and Figure 6 As shown, this embodiment proposes a pretreatment device for old kiln water with an early warning system, including a frame 1, and further including: an arc-shaped treatment shell 2, a water inlet early warning component 3, a scooping component, and a receiving tray 4; the arc-shaped treatment shell 2 is fixed on the frame 1 and is used to treat old kiln water; the water inlet early warning component 3 is connected to the frame 1 and is used to transport old kiln water into the arc-shaped treatment shell 2; the scooping component is set on the arc-shaped treatment shell 2 and is used to scoop flocculents and sediments inside the arc-shaped treatment shell 2; the receiving tray 4 is set on the frame 1 and is used to receive the flocculents and sediments scooped by the scooping component; wherein, the scooping component is provided with a feeding component to prevent the flocculents or sediments from adhering; Specifically, mine water enters the mine water treatment station for treatment through the water inlet warning component 3. During this period, the water quality is monitored in real time. When the water inlet warning component 3 detects a change in the water quality, that is, when the old kiln wastewater enters the mine water, the water is pretreated with alkali in the arc-shaped treatment shell 2 before being discharged to the mine water treatment station. The retrieval component can retrieve the flocs and sediments generated during the pretreatment process in real time and send them to the receiving tray 4. This prevents the generated flocs and sediments from hindering the collision and contact between the molecules of acidic and alkaline substances, which would slow down the neutralization reaction. The discharge of sediments and flocs can ensure the efficiency of wastewater pretreatment. By setting up an ingress warning component 3 to monitor environmental parameters such as water quality characteristics in real time, the equipment can be ensured to operate in the best working environment. It can play an early warning and forecasting role in preventing wastewater from the old kiln from entering the mine water system, and detect the situation of old kiln wastewater entering the system in advance. At the same time, the old kiln wastewater is pretreated by adding alkali using the arc-shaped treatment shell 2. The retrieval component is used to retrieve the sediment and flocculent matter generated in the arc-shaped treatment shell 2, so that the pretreated water enters the mine water treatment station, which reduces the operating load of the mine water treatment station and ensures that the mine water can meet the treatment standards.

[0026] like Figure 1 , Figure 5 and Figure 6 As shown, in a preferred embodiment, based on the above method, the water ingress warning component 3 further includes a water ingress main pipe 301 connected to the frame 1, and a water ingress pipe 302 and a return pipe 303 disposed between the water ingress main pipe 301 and the arc-shaped treatment shell 2. A first valve body is disposed between the water ingress pipe 302 and the return pipe 303 in the water ingress main pipe 301, and a second valve body and a third valve body are disposed at the water ingress pipe 302 and the return pipe 303, respectively. A water quality monitoring sensor 304 is disposed on the water ingress main pipe 301 and inside the arc-shaped treatment shell 2. The water quality monitoring sensor 304 is the prior art and can monitor the acidity, alkalinity, heavy metal content, etc. of the water body. Specifically, mine water enters through the main inlet pipe 301. With the first valve open and the second and third valves closed, the mine water enters the mine water treatment station through the main inlet pipe 301. During this period, the water quality monitoring sensor 304 monitors the water quality in the main inlet pipe 301. When the water quality monitoring sensor 304 detects that the acidity of the water in the main inlet pipe 301 exceeds the standard, the first valve is closed and the second valve is opened, allowing the water entering the main inlet pipe 301 to enter the arc-shaped treatment shell 2 through the inlet pipe 302. Treatment agents are added in the arc-shaped treatment shell 2 to pre-treat the old kiln wastewater. After the water quality monitoring sensor 304 in the arc-shaped treatment shell 2 detects that the water quality of the pre-treated water meets the standard, the third valve is opened, allowing the water in the arc-shaped treatment shell 2 to flow back to the main inlet pipe 301 through the return pipe 303. The water is then sent to the mine water treatment station for further treatment through the main inlet pipe 301.

[0027] like Figure 1 , Figure 3 , Figure 5 and Figure 7 As shown, in a preferred embodiment, based on the above method, the salvage assembly further includes mounting plates 5 fixed at both ends of the arc-shaped processing shell 2, a rotating rod 501 rotatably connected between the two mounting plates 5, a drive motor 502 fixed on one of the mounting plates 5 and used to drive the rotating rod 501 to rotate, and a material-pushing plate 503 evenly arranged circumferentially on the rotating rod 501. The end of the material-pushing plate 503 away from the rotating rod 501 moves against the inner wall of the arc-shaped processing shell 2. When the material-pushing plate 503 rotates, the movable contact design between the mesh plate 5033 and the inner wall of the arc-shaped processing shell 2 forms a dynamic gap, allowing the mesh plate 5033 to maintain relative freedom of movement during the flipping process, avoiding mechanical interference caused by the accumulation of impurities. Specifically, when the salvage component is working, the drive motor 502 is controlled to run. The output shaft of the drive motor 502 drives the rotating rod 501 to rotate. The rotating rod 501 drives the material-pulling plate 503 to rotate inside the arc-shaped treatment shell 2. The material-pulling plate 503 can move the water inside the arc-shaped treatment shell 2, thereby making the alkaline and acidic substances fully mixed. The treatment agent added inside the arc-shaped treatment shell 2 mixes with the sewage and reacts to generate precipitates or flocculents.

[0028] like Figure 1 , Figure 3 , Figure 5 , Figure 7 , Figure 9 , Figure 10 and Figure 11As shown, in a preferred embodiment, based on the above method, the material-dispensing plate 503 further includes an outer frame 5031 fixedly connected to the rotating rod 501 and a mesh plate 5033 rotatably connected to the outer frame 5031 via a pin 5032. The mesh holes on the mesh plate 5033 can ensure that the material-dispensing plate 503 will not dispense water out of the arc-shaped treatment shell 2 when scooping sediment or flocculent matter. A torsion spring for driving the mesh plate 5033 to reset and rotate is provided on the pin 5032. Furthermore, the arc-shaped treatment shell 2 includes an arc-shaped shell 201 and circular plates 202 fixed on both sides of the arc-shaped shell 201. The circular plate 202 includes an outer plate 2021 and an inner plate 2022 fixedly connected by a connecting plate, and an annular plate 2023 rotatably connected between the outer plate 2021 and the inner plate 2022. The outer wall of the outer plate 2021 is fixedly connected to the frame 1, and the pin 5032 is rotatably connected inside the annular plate 2023. The outer plate 2021 and the inner plate 2022 are fixed, while the annular plate 2023 rotates between them. It should be noted that the arc-shaped treatment shell 2 should be shut off when the water content is too high. The second valve body prevents the pre-treated mine water from continuing to enter the arc-shaped treatment shell 2. One side of the arc-shaped treatment shell 2 is slightly lower than the central axis to ensure that when the material-pulling plate 503 is removed from the arc-shaped treatment shell 2 during the retrieval operation, the material-pulling plate 503 is still in an inclined state. The sediment and flocculent matter on the material-pulling plate 503 will automatically slide down the inclined surface. This avoids the situation where the side of the arc-shaped shell 201 is higher than the central axis, causing the end of the material-pulling plate 503 away from the rotating rod 501 to be in a high position when it is removed from the arc-shaped shell 201, and the debris on the mesh plate 5033 cannot be smoothly discharged from the arc-shaped treatment shell 2. Furthermore, the feeding assembly includes a driven gear 5034 disposed at the end of the pin shaft 5032. A rack frame 6 that meshes with the driven gear 5034 is also disposed between the outer plate 2021 and the inner plate 2022. The rack frame 6 includes an outer rack 601 connected to the outer plate 2021 via a connecting plate and an inner rack 602 connected to the inner plate 2022 via a connecting plate. The outer rack 601 and the inner rack 602 alternately mesh with the driven gear 5034. It should be noted that the driven gear 5034 that rotates with the annular plate 2023 and the large gear ring 11 will not collide or interfere with the rack frame 6 when they rotate. Specifically, during the operation of the salvage assembly, the rotation of the material-dispensing plate 503 can dislodge sediment or flocculent matter in the water. When the material-dispensing plate 503 moves out of the arc-shaped housing 201, some flocculent matter and sediment will slide down along the inclined material-dispensing plate 503 and fall into the receiving tray 4. As the rotating rod 501 drives the material-dispensing plate 503 to continue rotating, the driven gear 5034 on the pin shaft 5032 meshes with the rack frame 6, and the mesh plate 5033 rotates around the pin shaft 5032 as the center. This causes the screen plate 5033 to flip relative to the outer frame 5031, so that the side that originally moved the sediment and flocculent matter flips downwards, making it easier for the sediment and flocculent matter to fall down; and when the screen plate 5033 flips downwards, the driven gear 5034 alternately meshes with the outer rack 601 and inner rack 602 on the rack frame 6, so that the pin 5032 drives the screen plate 5033 to swing back and forth, and the sediment and flocculent matter on the screen plate 5033 falls down quickly, improving the cleaning effect of debris on the material feeding plate 503.

[0029] like Figure 1 , Figure 3 , Figure 4 and Figure 9 As shown, in a preferred embodiment, based on the above method, an eccentric rod 7 is further provided on the rotating rod 501, a collar 701 is sleeved on the eccentric rod 7, a swing rod 702 is fixedly connected to the collar 701, and a sliding rod 703 is movably connected to the end of the swing rod 702 away from the collar 701. The sliding rod 703 is fixedly connected to the receiving tray 4 through a connecting plate, and the receiving tray 4 is slidably connected to the frame 1. Specifically, when the rotating rod 501 rotates, it can drive the collar 701 to move through the eccentric rod 7. When the collar 701 moves, it drives the swing rod 702 to move. The swing rod 702 drives the slide rod 703 to slide axially back and forth. When the slide rod 703 moves, it drives the receiving tray 4 to move back and forth on the frame 1, so that the sediment or flocculent material falling into the receiving tray 4 is evenly spread, ensuring the storage space in the receiving tray 4. This allows the receiving tray 4 to make the most of its internal space to store sediment or flocculent material, avoiding the accumulation of sediment or flocculent material that affects its storage and reducing the cleaning cycle for workers. A sensor can be installed in the receiving tray 4 to monitor the internal capacity. When the internal sediment accumulates to 90% of the capacity, an early warning is issued to prompt workers to clean it.

[0030] like Figure 1 , Figure 3 , Figure 4 and Figure 9As shown, in a preferred embodiment, based on the above method, a support base 8 is fixed on the frame 1, and a sleeve 801 that is slidably connected to the slide rod 703 is fixed on the support base 8. Lithium-based grease is evenly applied to the contact section between the slide rod 703 and the sleeve 801 to avoid wear of the parts due to friction, resulting in sliding jamming or abnormal noise. A piston 7031 that is slidably connected to the inner wall of the sleeve 801 is fixed on the slide rod 703. The piston 7031 divides the inner cavity of the sleeve 801 into a first cavity and a second cavity. An air inlet valve and an air outlet valve are provided on both the first cavity and the second cavity. An air guide pipe 802 is connected to the air outlet valve of both the first cavity and the second cavity. The ends of the two air guide pipes 802 are connected to the same air collecting pipe 803. The air collecting pipe 803 is connected to an exhaust pipe 804 through a rotating joint. A support plate 9 connected to the exhaust pipe 804 is fixed on the circular plate 202. Several evenly distributed nozzles 805 are provided on the exhaust pipe 804. Specifically, when the swing rod 702 drives the slide rod 703 to move back and forth, the slide rod 703 drives the piston 7031 to move back and forth within the sleeve 801. The first and second chambers within the sleeve 801 alternately draw in and exhaust air. The exhaust air enters the exhaust pipe 804 through the air guide pipe 802 and the air collecting pipe 803, and is sprayed onto the flipped screen plate 5033 through the nozzle 805. Since the sediment and flocculent matter are located on the lower side of the screen plate 5033 at this time, the cleaning effect on sediment and flocculent matter that are not easy to fall off from the material feeding surface of the screen plate 5033 is further improved. It should be noted that, because the first and second chambers alternately draw in and exhaust air, the exhaust pipe 804 always discharges air outward through the nozzle 805 for purging, and there will be no intermittent purging by the nozzle 805 due to only one chamber drawing in and exhausting air.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 9 As shown, in a preferred embodiment, based on the above method, the exhaust pipe 804 is rotatably connected to the support plate 9 and a torsion spring is provided between them. One end of the exhaust pipe 804 is fixedly provided with a movable gear 10, and a large gear ring 11 that meshes with the movable gear 10 is fixedly provided on the annular plate 2023. The large gear ring 11 is provided with a plurality of empty parts 111. The large gear ring 11 and the driven gear 5034 are not on the same plane. Specifically, during the operation of the salvage component, the material-feeding plate 503 rotates, driving the annular plate 2023 to rotate via the pin 5032. The annular plate 2023 rotates relative to the outer plate 2021 and the inner plate 2022. When the annular plate 2023 rotates, it drives the large gear ring 11 to rotate. The large gear ring 11 meshes with the movable gear 10, which drives the exhaust pipe 804 to rotate relative to the support plate 9. The exhaust pipe 804 drives the nozzle 805 to adjust the spray angle, so that the nozzle 805 can spray the sediment or flocculent material that is not easy to fall off from the underside of the mesh plate 5033 from different angles. The nozzle 805 can be a duckbill type to enhance the cleaning effect of impurities on the mesh plate 5033. It should be noted that since there are several empty parts 111 on the large gear ring 11, when the empty parts 111 of the large gear ring 11 rotate to the movable gear 10, the movable gear 10 is no longer driven, and the exhaust pipe 804 is reset and rotated under the action of the torsion spring, so that the exhaust pipe 804 reciprocates with the operation of the retrieval component, ensuring the cleaning effect of impurities on the material-pulling plate 503, thereby improving the pretreatment efficiency and pretreatment effect of the water inside the arc-shaped treatment shell 2.

[0032] This invention also discloses a method for pretreating old kiln water with an early warning system, which involves treating the water using the aforementioned old kiln water pretreatment device with an early warning system, and includes the following steps: S1: Mine water enters through the main inlet pipe 301. With the first valve body open and the second and third valve bodies closed, the mine water enters the mine water treatment station through the main inlet pipe 301. During this period, the water quality monitoring sensor 304 monitors the water quality in the main inlet pipe 301. When the water quality monitoring sensor 304 detects that the acidity of the water in the main inlet pipe 301 exceeds the standard, it closes the first valve and opens the second valve, so that the water entering the main inlet pipe 301 enters the arc-shaped treatment shell 2 through the inlet pipe 302. S2: Alkaline substances are added inside the arc-shaped treatment shell 2 to react with acidic substances in the water to generate precipitates or flocculents; The drive motor 502 is controlled to run. The output shaft of the drive motor 502 drives the rotating rod 501 to rotate. The rotating rod 501 drives the material-pulling plate 503 to rotate inside the arc-shaped treatment shell 2. The material-pulling plate 503 can poke the water inside the arc-shaped treatment shell 2, thereby making the alkaline and acidic substances fully mixed. When the material-dispensing plate 503 rotates, it can dissipate sediments or flocs in the water. When the material-dispensing plate 503 moves out of the arc-shaped shell 201, some flocs and sediments will slide down along the tilted material-dispensing plate 503 and fall into the receiving tray 4. S3: As the rotating rod 501 drives the material feeding plate 503 to continue rotating, the driven gear 5034 on the pin 5032 meshes with the rack frame 6, and the screen plate 5033 rotates around the pin 5032 as the center, causing the screen plate 5033 to flip relative to the outer frame 5031, so that the side that originally moved the sediment and flocculent matter flips down, making it easier for the sediment and flocculent matter to fall; Furthermore, when the screen plate 5033 flips downwards, the driven gear 5034 alternately meshes with the outer rack 601 and the inner rack 602 on the rack frame 6, causing the pin 5032 to drive the screen plate 5033 to swing back and forth, and the sediment and flocculent matter on the screen plate 5033 fall down quickly. S4: When the rotating rod 501 rotates, it drives the collar 701 to move through the eccentric rod 7. When the collar 701 moves, it drives the swing rod 702 to move. The swing rod 702 drives the slide rod 703 to slide back and forth axially. When the slide rod 703 moves, it drives the receiving tray 4 to move back and forth on the frame 1, so that the sediment or flocculent material falling into the receiving tray 4 is evenly spread, ensuring the storage space in the receiving tray 4. S5: As the rotating rod 501 drives the material-pulling plate 503 to continue rotating, the driven gear 5034 no longer meshes with the rack frame 6, and the pin 5032 drives the mesh plate 5033 to reset under the action of the torsion spring. When it rotates into the arc-shaped shell 201, it continues to dredge the sediment and flocculent matter in the water. S6: After the water in the arc-shaped treatment shell 2 has been pretreated, the second valve body is closed and the third valve body is opened. The treated water in the arc-shaped treatment shell 2 flows back from the return pipe 303 to the main water inlet pipe 301 and enters the mine water treatment station through the main water inlet pipe 301. When the water quality monitoring sensor 304 on the main inlet pipe 301 detects that the acidity of the water is lower than the treatment standard, the second and third valve bodies are closed and the first valve body is opened, so that the water is directly transported from the main inlet pipe 301 to the mine water treatment station.

When the water quality monitoring sensor (304) detects that the acidity of the water in the main inlet pipe (301) exceeds the standard, the first valve body is closed and the second valve body is opened, so that the water entering the main inlet pipe (301) enters the arc-shaped treatment shell (2) through the inlet pipe (302).
