Description

Technical Field

[0001] This invention relates to the field of water treatment technology, and more specifically to a pretreatment destabilization and crystallization device. Background Technology

[0002] Coal mines refer to underground or surface mining sites for extracting coal resources. During underground coal mining, methods such as tunnels and shafts are typically used. Therefore, groundwater from nearby areas may seep through the ore layers and accumulate in the mine, forming mine water. To prevent mine tunnels from collapsing due to the soaking of mine water, pumps are used to remove the mine water promptly. However, because mine water may contain various minerals, organic matter, or other harmful substances, it requires a series of treatments such as softening, sedimentation, and filtration before discharge to prevent it from impacting the nearby ecological environment if discharged into natural rivers. Traditional softening methods often involve directly adding softening agents to coal mine water. This causes calcium, magnesium, and carbonate ions in the water to exchange ions under the influence of anions in the softening agent, forming precipitates. However, these precipitates are often loose, with disordered, large particles containing significant amounts of water and impurities, making them difficult to collect and dry. This significantly increases the difficulty and operating costs of sludge treatment, reduces the recycling value of the precipitates, and fails to meet the principles of green production. Furthermore, to ensure thorough mixing of the artificial additives with the coal mine water and avoid excessive addition and waste, large stirring rods are commonly used to agitate the water in the container, further increasing energy consumption. Currently, there is a lack of simple and effective solutions to these technical problems. Summary of the Invention

The collection chamber opens when it descends to a first preset height and closes when it rises to a second preset height. The sliding opening and closing mechanism communicates with the space outside the processing cylinder when it is open. A movable sealing member is provided corresponding to the first opening. The movable sealing member can block the first opening when the collection chamber descends to a third preset height and release the blockage when the collection chamber rises to a fourth preset height. The processing cylinder is provided with an inner cylinder. The opening height of the inner cylinder inside the processing cylinder is higher than the top of the collection chamber. The inner cylinder communicates with the space outside the processing cylinder.

[0005] Optionally, the sliding opening and closing mechanism includes a first cylinder and a second cylinder, which are coaxially arranged and can reciprocate with each other when the collection chamber moves in the vertical direction. The outer wall of the first cylinder abuts against the inner wall of the second cylinder.

[0006] Optionally, the movable sealing member is disposed above the first cylinder so that when the collection bin moves in the vertical direction, the movable sealing member reciprocates relative to the collection bin, so as to seal the first opening when the collection bin descends to a third preset height, and release the seal on the first opening when the collection bin rises to a fourth preset height.

[0007] Optionally, the reaction component includes a first raft, and the processing cylinder is provided with a first limiting member, which is used to make the first raft reciprocate within a limited height range.

[0018] Optionally, the collection pool is provided with a collection plate, and the third opening is positioned facing the surface of the collection plate.

[0019] The pretreatment destabilization crystallization equipment provided by this invention has the following beneficial effects:

[0020] This invention provides a pretreatment destabilization crystallization device, including a processing cylinder. Near the top of the processing cylinder, an inlet and a feeding mechanism are provided; the feeding mechanism is used to add seed crystals. A collection chamber is located at the bottom of the processing cylinder, and a first opening is located at the top of the collection chamber. The collection chamber is connected to a reaction force component, which provides a force opposite to the direction of gravity of the collection chamber. The reaction force component and the collection chamber can reciprocate vertically relative to the processing cylinder together. A sliding opening and closing mechanism is provided at the bottom of the collection chamber, which allows for [further movement] within the collection chamber. The collection chamber opens when it descends to a first preset height and closes when it rises to a second preset height. The sliding opening and closing mechanism communicates with the space outside the processing cylinder when it is open. A movable sealing member is provided corresponding to the first opening. The movable sealing member can block the first opening when the collection chamber descends to a third preset height and release the blockage when the collection chamber rises to a fourth preset height. The processing cylinder is provided with an inner cylinder. The opening height of the inner cylinder inside the processing cylinder is higher than the top of the collection chamber. The inner cylinder communicates with the space outside the processing cylinder.

[0021] With this configuration, when mine water enters the treatment cylinder through the inlet, seed crystals also enter the cylinder via the feeding mechanism. There, they react chemically with the mine water to form precipitate. The precipitate, being relatively heavy, sinks within the cylinder until it reaches the top of the collection chamber and enters through the first opening. As the precipitate accumulates, the weight on the collection chamber gradually exceeds the reaction force provided by the reaction component, causing the collection chamber to descend. This activates the sliding opening and closing mechanism, discharging the precipitate. As the precipitate is discharged, the weight inside the collection chamber decreases, and the reaction component pulls it back upwards, closing the sliding opening and closing mechanism. This process repeats continuously, creating a phased discharge. In this reciprocating process, the movable sealing component can seal the first opening when the collection chamber descends to a third preset height, preventing the sediment from continuously flowing in. After the collected sediment is discharged through the sliding opening and closing mechanism, the collection chamber is pulled upward by the reaction component. When the collection chamber rises to a fourth preset height, the seal on the first opening is released, allowing subsequent sediment to continue entering the collection chamber. Furthermore, since the opening height of the inner cylinder inside the processing cylinder is higher than the top of the collection chamber, and the inner cylinder is connected to the space outside the processing cylinder, the sediment will sink through the first opening and then be discharged through the sliding opening and closing mechanism. The sediment will hardly be able to enter the inner cylinder, thus achieving the separation of sediment and water. This invention utilizes heterogeneous seed crystals to enable target ions in coal mine water to rapidly crystallize along the seed crystal surface in a supersaturated metastable state, thereby achieving rapid solid-liquid separation. This avoids the generation of large amounts of precipitates due to the direct addition of softeners. Furthermore, the cooperation between the collection chamber, the sliding opening and closing mechanism, and the movable sealing component allows the crystals to be automatically removed from the processing cylinder after a certain number of crystals have accumulated, overcoming the buoyancy of the raft. This does not affect the normal use of the seed crystals. In summary, this invention achieves the goal of efficiently removing ions from water while effectively separating, collecting, and recycling precipitates, reducing production costs and conforming to the concept of green production.

[0047] The purpose of this invention is to provide a pretreatment destabilization crystallization device to achieve more efficient collection of precipitates.

[0048] The technical solution of the present invention will be described in detail below with reference to specific embodiments. It should be understood that the present invention is not limited to specific embodiments.

[0049] Please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the pretreatment destabilization and crystallization equipment provided in an embodiment of the present invention; Figure 2 This is a schematic diagram of the pretreatment destabilization and crystallization equipment provided in one embodiment of the present invention from another perspective. Figure 1 and Figure 2 Removing shell 1 from the middle can yield the following: Figure 3The diagram shown is an overall schematic of the internal structure of the pretreatment destabilization and crystallization equipment. Figure 3 The processing cylinder 6 can be seen in the image. The processing cylinder 6 will be described in detail below.

[0050] Please refer to Figures 4 to 6 , Figure 4 A cross-sectional view of the processing cylinder from a first perspective provided in an embodiment of the present invention; Figure 5 This is a cross-sectional view of the processing cylinder from a second perspective according to an embodiment of the present invention; Figure 6 for Figure 5 A magnified view of a portion of region A in the diagram. (See diagram below.) Figures 4 to 6 As shown, the processing cylinder 6 has a water inlet 25 and a feeding mechanism 3 near its top. The feeding mechanism 3 is used to feed seed crystals. The bottom of the processing cylinder 6 has a collection chamber 8, and the top of the collection chamber 8 has a first opening 130. The collection chamber 8 is connected to a reaction component B, which provides a force opposite to the gravity of the collection chamber 8. The reaction component B and the collection chamber can reciprocate vertically relative to the processing cylinder 6 together. The bottom of the collection chamber 8 has a sliding opening and closing mechanism 12, which can open and close when the collection chamber 8 descends to a first preset height. The mechanism is open and closes when the collection chamber 8 rises to a second preset height. When open, the sliding opening and closing mechanism 12 communicates with the space outside the processing cylinder 6. A movable sealing member 13 is correspondingly provided for the first opening 130. The movable sealing member 13 can block the first opening 130 when the collection chamber 8 descends to a third preset height and release the blockage when the collection chamber 8 rises to a fourth preset height. The processing cylinder 6 is provided with an inner cylinder 7. The opening height of the inner cylinder 7 in the processing cylinder 6 is higher than the top of the collection chamber 8. The inner cylinder 7 communicates with the space outside the processing cylinder 6.

[0051] It should be understood that the application of this invention in the treatment of coal mine well water involves gravity. Therefore, in this invention, "upper" refers to the direction away from the ground, "lower" refers to the direction close to the ground, "vertical" refers to the direction perpendicular to the ground, and "lateral" refers to the direction parallel to the ground.

[0052] With this configuration, when mine water enters the treatment cylinder 6 through the inlet 25, seed crystals also enter the treatment cylinder 6 via the feeding mechanism 3. There, they react chemically with the mine water to form precipitate. The precipitate, being relatively heavy, sinks in the treatment cylinder 6 until it reaches the top of the collection chamber 8 and enters through the first opening 130. As the precipitate accumulates, the gravity acting on the collection chamber 8 gradually exceeds the reaction force provided by the reaction component B, causing the collection chamber 8 to descend. This activates the sliding opening and closing mechanism 12, discharging the precipitate. As the precipitate is discharged, the weight inside the collection chamber 8 decreases, and it is pulled upwards by the reaction component B, closing the sliding opening and closing mechanism. This process repeats continuously, creating a phased discharge. In this reciprocating process, the movable sealing component 13 can block the first opening 130 when the collection chamber 8 descends to the third preset height, preventing the sediment from continuously flowing in. After the collected sediment is discharged through the sliding opening and closing mechanism 12, the weight inside the collection chamber 8 decreases and is pulled upward by the reaction force component B. When the collection chamber 8 rises to the fourth preset height, the blockage of the first opening 130 is released, and subsequent sediment can continue to enter the collection chamber 8. Furthermore, since the opening height of the inner cylinder 7 inside the processing cylinder 6 is higher than the top of the collection chamber 8, and the inner cylinder 7 is connected to the space outside the processing cylinder 6, the sediment will sink through the first opening 130 and then be discharged through the sliding opening and closing mechanism 12. The sediment will hardly be able to enter the inner cylinder 7. To further prevent sediment from entering the inner cylinder 7, a shield 312 can also be provided. The shield 312 allows water to pass through and blocks the sediment as much as possible, thereby achieving the separation of sediment and water.

[0053] This invention utilizes heterogeneous seed crystals to enable target ions in coal mine water to rapidly crystallize along the seed crystal surface in a supersaturated metastable state, thereby achieving rapid solid-liquid separation. This avoids the generation of large amounts of precipitates due to the direct addition of softeners. Furthermore, the cooperation between the collection chamber 8, the sliding opening and closing mechanism 12, and the movable sealing component 13 allows the crystals to be automatically removed from the processing cylinder 6 after a certain number of crystals have accumulated, overcoming the buoyancy of the raft. This does not affect the normal use of the seed crystals. In summary, this invention achieves the goal of effectively separating, collecting, and recycling precipitates while efficiently removing ions from water, reducing production costs and conforming to the concept of green production.

[0054] Please continue to refer to this. Figure 6In one exemplary embodiment, the sliding opening and closing mechanism 12 includes a first cylinder 121 and a second cylinder 122. The first cylinder 121 and the second cylinder 122 are coaxially arranged and can reciprocate with each other when the collection chamber 8 moves in the vertical direction (for example, the first cylinder 121 is connected to the bottom of the collection chamber 8 to achieve synchronous movement, and the second cylinder 122 is slidably connected to the first cylinder 121). The outer wall of the first cylinder 121 abuts against the inner wall of the second cylinder 122. A second opening 120 is provided on the side wall of the first cylinder 121 or the second cylinder 122 so that when the collection chamber 8 descends to a first preset height, the second opening 120 is exposed and opened, and when the collection chamber 8 rises to a second preset height, the second opening 120 is blocked and closed.

[0055] Please continue to refer to this. Figure 6 Furthermore, the movable sealing member 13 is disposed above the first cylinder 121 so that when the collection chamber 8 moves in the vertical direction, the movable sealing member 13 reciprocates relative to the collection chamber 8, so as to achieve the sealing of the first opening 130 when the collection chamber 8 descends to the third preset height, and to release the sealing of the first opening 130 when the collection chamber 8 rises to the fourth preset height.

[0056] Please refer to Figure 7 , Figure 7 This is a partially enlarged schematic diagram of the reaction component B provided in an embodiment of the present invention. Figure 7As shown, the reaction component B includes a first raft 9, and a first limiting member is provided inside the processing cylinder 6. The first limiting member is used to allow the first raft 9 to reciprocate within a limited height range. In an exemplary embodiment, the first limiting member includes a first limiting block 10 and a second limiting block 11. The first limiting block 10 passes through the side wall of the inner cylinder 7 and can reciprocate radially along the inner cylinder 7. The side wall of the inner cylinder 7 is provided with a limiting cavity, so that the first limiting block 10 can reciprocate radially along the inner cylinder 7 within the space limited by the limiting cavity. The second limiting block 11 is located above the first raft 9. The end of the first limiting block 10 away from the inner cylinder 7 is provided with an inclined surface, and the end of the second limiting block 11 near the inner cylinder 7 is also provided with an inclined surface. The inclined surfaces of the first limiting block 10 and the second limiting block 11 abut against each other and can reciprocate. When there is coal mine water in the treatment cylinder 6, the first raft 9 receives an upward buoyancy force, causing the reaction component B to provide an upward pull to the collection chamber 8. When there is a large amount of sediment accumulation in the collection chamber 8, the gravity of the collection chamber 8 is greater than the upward pull provided by the reaction component B to the collection chamber 8, and the reaction component B moves downward. After the sediment in the collection chamber 8 is discharged, the gravity of the collection chamber 8 decreases, and the reaction component B pulls the collection chamber 8 upward. During this process, because the inclined surfaces of the first limiting block 10 and the second limiting block 11 abut against each other and can reciprocate, reciprocating motion occurs. Furthermore, because the first limiting block 10 passes through the side wall of the inner cylinder 7 and can reciprocate radially along the inner cylinder 7, it pushes the first limiting block 10 to reciprocate radially along the inner cylinder 7. Further, the side wall of the inner cylinder 7 has a limiting cavity, so the first limiting block 10 can only move in a limited manner. This limited sliding restricts the up-and-down movement of the second limiting block 11, ultimately enabling the first raft 9 to reciprocate within a limited height range. It should be understood that the first limiting component can also be configured in other ways, which will not be elaborated here.

[0057] Please continue to refer to this. Figure 4 and Figure 5 ,like Figure 4 and Figure 5As shown, the sliding opening and closing mechanism 12 communicates with the space outside the processing cylinder 6 via a connecting pipe 15. A filter screen 14 is provided on the side wall of the connecting pipe 15, and the connecting pipe 15 communicates with the water collection tank 201 via the filter screen 14. This arrangement is because the precipitate may contain some incompletely reacted seed crystals, and the particle size of these seed crystals is smaller than the precipitate. Therefore, these seed crystals can be collected again in the water collection tank 201 using the filter screen for recycling. To achieve recycling, a reflux mechanism 2 should also be included. The reflux mechanism 2 includes a reflux pipe 202, a portion of which is located in the water collection tank 201. The input end of the reflux pipe 202 is located near the bottom of the water collection tank 201, and the output end of the reflux pipe 202 communicates with the processing cylinder 6 and is located near the top of the processing cylinder 6. When mine water continuously enters the treatment cylinder 6 through the inlet 25, a negative pressure is generated in the treatment cylinder 6 relative to the water collection chamber 201. This forces water from the water collection chamber 201 into the treatment cylinder 6, thereby achieving seed crystal recovery. Preferably, a connecting cylinder 26 can also be provided between the collection chamber 8 and the treatment cylinder 6. The surface of the connecting cylinder 8 has mesh openings to allow seed crystal recovery also to be performed in the area of ​​the collection chamber 8.

[0058] Please refer to Figure 8 , Figure 8 for Figure 5 A magnified view of a portion of region C. (See attached image.) Figure 8 As shown, a movable shield is fitted onto the return pipe 202 located in the water collection tank 201. The movable shield can reciprocate vertically relative to the return pipe 202. The movable shield includes a second raft 204 and a sleeve 203. The sleeve 203 is fitted onto the return pipe 202 and serves as a carrier for the reciprocating motion of the movable shield. When water gradually accumulates in the water collection tank 201, the second raft 204 is buoyed and gradually raises the movable shield. At this time, the input end of the return pipe 202 is exposed, and water can enter the return pipe 202. When there is no water in the water collection tank 201, the second raft 204 falls to the bottom of the water collection tank 201 and blocks the input end of the return pipe 202.

The recovery cylinder 16 includes a pushing mechanism 22, a rotating mechanism, and multiple holding boxes 21. The multiple holding boxes 21 are arranged circumferentially along the rotating mechanism. The connecting pipe 15 is connected to the holding boxes 21 (e.g., ...). Figure 9 The outlet of the connecting pipe 15 is positioned above the opening of the container 21 so that sediment can flow into the container 21 through the connecting pipe 15; the rotating mechanism includes a rotating shaft 19 and a toothed plate 24, the rotating shaft 19 being drivenly connected to the toothed plate 24. Specifically, a gear 17 is provided at the bottom of the rotating shaft 19, the gear 17 meshing with the toothed plate 24, so that when the toothed plate 24 moves, the rotating shaft 19 rotates around an axis, the container 21 can rotate around the axis when the rotating shaft 19 rotates around the axis, and the container 21 can reciprocate vertically relative to the rotating mechanism (e.g., Figures 9 to 11 A support plate 20 is provided to support the container 21. The support plate 20 can rotate around the axis when the rotating shaft 19 rotates around the axis and can drive the container 21 to move vertically reciprocally relative to the rotating mechanism. The pushing mechanism 22 is located below the container 21. The pushing mechanism 22 can be pushed downward by the container 21. The pushing mechanism 22 is connected to the toothed plate 24 by a first connecting member 23, so that when the pushing mechanism 22 is pushed, the first connecting member 23 drives the toothed plate 24 to move. With this configuration, when the sediment enters one of the containers 21 through the connecting pipe 15, the weight in the container 21 gradually increases, thereby pushing the pushing mechanism 22 downwards. When the pushing mechanism 22 is pushed, the first connecting member 23 drives the toothed plate 24 to move. As the toothed plate moves, the rotating shaft 19 rotates around an axis. When the rotating shaft 19 rotates around the axis, the container 21 rotates around the axis, causing another empty container 21 to rotate below the connecting pipe 15, allowing the sediment to flow back into that container 21. This configuration allows multiple containers 21 to collect the sediment in batches. The side wall of the recovery cylinder 16 should be provided with an opening door. Opening the opening door allows for the replacement of the container 21. Specifically, a groove can be opened at the bottom of the container 21 for a forklift to insert and lift it. Alternatively, other methods can be used to replace the container 21, which will not be elaborated here.

[0060] Please continue to refer to this. Figures 9 to 11Furthermore, the recycling cylinder 16 also includes a self-resetting mechanism, which is used to move the pushing mechanism 22 upward. Specifically, the self-resetting mechanism includes a counterweight 29, a reversing element 27 (which can be a fixed pulley or a U-shaped frame), and a steel wire rope 28. One end of the steel wire rope 28 is connected to the counterweight 29, and the steel wire rope is laid on the reversing element 27. The other end of the steel wire rope 28 is connected to the pallet 20 or the pushing mechanism 22. The weight of the counterweight 29 enables the steel wire rope 28 to exert an upward pulling force on the pallet 20 or the pushing mechanism 22. Thus, when there is a lot of sediment in the container 21, the downward pushing force on the pallet 20 or the pushing mechanism 22 is greater than the upward pulling force. However, when the container 21 is replaced and its weight decreases, the downward pushing force on the pallet 20 or the pushing mechanism 22 is less than the upward pulling force. At this time, the pallet 20 or the pushing mechanism 22 will be pulled upward, achieving self-resetting. Similarly, an elastic element, such as a spring 30, can be provided on the lower surface of the pushing mechanism 22, so that the pushing mechanism 22 is subjected to an upward elastic force from the spring 30. Therefore, when there is a large amount of sediment in the container 21, the downward thrust on the pushing mechanism 22 is greater than the upward elastic force. However, when the container 21 is replaced and its weight decreases, the downward thrust on the pushing mechanism 22 is less than the upward elastic force. At this time, the tray 20 or the pushing mechanism 22 will spring back upward, achieving self-resetting. The self-resetting mechanism and the rotating mechanism can be simultaneously attached to the connecting frame 18 to be accommodated in the overhead area provided by the connecting frame 18.

[0061] Please refer to Figure 5 and Figure 13 , Figure 13 for Figure 5 An enlarged diagram of region D in the middle, as shown below. Figure 5 and Figure 13As shown, the feeding mechanism 3 includes a rotating feeding unit capable of rotating around its own axis. Specifically, the rotating feeding unit may include an impeller 301 and a rotating rod 302, so that the rotating feeding unit can rotate around its own axis by external energy. The rotating feeding unit also includes a plurality of feed pipes 304 arranged sequentially from the inside to the outside, with a cavity formed between two adjacent feed pipes. Each feed pipe 304 closer to the inside protrudes along the axial direction of the rotating feeding unit relative to the feed pipes 304 arranged on the outside, and a discharge port 305 is opened on the side wall of the protruding part. In an exemplary embodiment, seed crystals are first added to the feeding chamber 310. A first rotating plate 306 and a second rotating plate 308 are provided between the feeding chamber 310 and the input end of the feed pipe 304. The first rotating plate 306 has a first discharge port 307, and the second rotating plate 308 has a second discharge port 309. Both the first rotating plate 306 and the second rotating plate 308 can rotate around an axis, and during their rotation, the first discharge port 307 and the second discharge port 309 can at least partially overlap, allowing the seed crystals to enter each feeding pipe 304 from the feeding bin 310. Each feeding pipe 304 rotates synchronously, causing centrifugal motion in the seed crystals, which then disperse from each sprinkling port 305, achieving uniform entry into the processing cylinder 6. Each sprinkling port 305 may also be equipped with a turntable 303. The side of the turntable 303 near the rotating rod 302 can be connected to the rotating rod 301, and the side away from the rotating rod 302 can be connected to the feeding pipe 304, achieving limited transmission and buffering of the torsional force of the rotating rod 301. The turntable 303 may include multiple layers, each layer being connected and fixed using a support frame 313.

[0062] Please refer to Figure 3 , Figure 14 , Figure 15 , Figure 16 , Figure 17 , Figure 14 This is an overall schematic diagram of the sedimentation tank from a first perspective according to an embodiment of the present invention; Figure 15 This is a schematic diagram of the sedimentation tank from a second perspective according to an embodiment of the present invention; Figure 16 This is a third overall view of the sedimentation tank provided in an embodiment of the present invention; Figure 17This is a fourth overall schematic diagram of the sedimentation tank provided in an embodiment of the present invention. The inner cylinder 7 is connected to the impurity removal mechanism 4 via a guide pipe 402. The impurity removal mechanism 4 includes a sedimentation tank 401, which includes a reaction tank and a collection tank. The sedimentation tank is separated into the reaction tank and the collection tank by a first partition 418. A third opening 419 is provided on the first partition 418 to allow communication between the reaction tank and the collection tank. The reaction tank is divided into several sub-reaction tanks 403 by several vertically arranged second partitions 404. The guide pipe 402 is connected to the sub-reaction tank 403 furthest from the collection tank. The second partition is divided into a bottom perforated plate and a top slotted plate. The top slotted plate and the bottom perforated plate are alternately arranged. The second partition of the sub-reaction tank 403 connected to the guide pipe is the top slotted plate. In one exemplary embodiment, the sub-reaction tanks 403 can be arranged in two columns. The second partition 404 between two adjacent sub-reaction tanks 403 in different columns is a top slotted plate with a slot 405 at the top. The second partition 404 between two adjacent sub-reaction tanks 403 in the same column is a bottom perforated plate with a fourth opening 406 at the bottom. With this configuration, the water flow first enters the first sub-reaction tank 403 through the guide pipe 402, and then enters the second sub-reaction tank 403 through the slot 405 of the first sub-reaction tank 403. The second partition 404 between the second and third sub-reaction tanks 403 is a bottom perforated plate, so the water flow enters the third sub-reaction tank 403 through the fourth opening 406. The second partition 404 between the third and fourth sub-reaction tanks 403 is a top slotted plate, so the water flow enters the fourth sub-reaction tank 403 through the slot 405. This cycle repeats, thereby controlling the flow path of the water and allowing each sub-reaction tank 403 to be processed accordingly, forming a production line-style processing.

[0063] Please continue to refer to this. Figures 14 to 17 Each of the sub-reaction tanks 403 has a vertically arranged limiting rod 417 at its bottom. A sleeve 415 is fitted onto the limiting rod 417 and is slidably connected to the limiting rod 417. A mesh plate 416 is provided on the outer periphery of the sleeve 415. One end of the sleeve 415 away from the limiting rod 417 is hinged to a second connecting member 414. One end of the second connecting member 414 away from the sleeve 415 is hinged to a horizontally arranged moving member 412. When the moving member 412 moves horizontally, it can drive the second connecting member 414 to move, thereby driving the sleeve 415 and the mesh plate 416 to reciprocate vertically, thereby agitating the water in each sub-reaction tank 403 and ensuring that the water in each reaction tank reacts fully during treatment.

[0064] Please continue to refer to this. Figures 14 to 17 The movable component 412 has a dosing hole 413. The movable component 412 is slidably connected to a sliding shield, so that when the movable component 412 moves in the horizontal direction, the sliding shield switches between two states: blocking the dosing hole 413 and exposing the dosing hole 413. Specifically, the sliding shield includes a fixed plate 409, a hydraulic rod 410, and a dosing chamber 407. The bottom of the dosing chamber has corresponding holes 408 that correspond one-to-one with the dosing hole 413. The hydraulic rod uses an L-shaped plate 411 to drive the dosing chamber 407 to reciprocate in the horizontal direction. The dosing chamber 407 is also divided into multiple sub-dosing chambers, and each sub-dosing chamber, each corresponding hole 408, each dosing hole 413, and each sub-reaction tank 403 corresponds one-to-one. Add the corresponding additive to each of the sub-dosing chambers. When the dosing chamber 407 reciprocates, the dosing hole 413 and the corresponding hole 408 can at least partially overlap. At this time, the dosing hole 413 is exposed, and the additive in the sub-dosing chamber enters the sub-reaction tank 403 to treat the water.

[0065] After being treated in the reaction tank, the water, mixed with sediment, flows into the collection tank through the third opening 419. The bottom of the collection tank includes an inclined member 423 and a pushing member 424. The upper surface of the inclined member 423 is angled relative to the bottom surface of the collection tank to form an incline. The pushing member 424 is located at the bottom end of the incline and can provide thrust in a predetermined direction. Specifically, the pushing member 424 is an auger. After the sediment enters the collection tank, it sinks to the bottom of the collection tank and is guided by the incline to sink to the auger. The auger pushes the sediment to the target position to complete the collection. After collection, the sediment is discharged by the sludge pipe 426 and the sludge pump 427, while the treated water is discharged from the drain pipe 428.

[0066] Furthermore, the collection pool is equipped with a collection plate 421, and the third opening 419 is positioned facing the surface of the collection plate 421. This arrangement allows sediment in the water flowing from the third opening 419 to be more easily blocked by the collection plate 421, thus causing it to sink to the bottom of the collection pool more quickly. Multiple collection plates 421 can be fixed within a predetermined spatial range using a fixing frame 420.
