Description

Technical Field

[0001] The present invention relates to the technical field of annular cooler dredging, and in particular to an annular cooler system with a dredging function and a dredging method. Background Art

[0002] Annular coolers are key equipment in the production line of finished sintered ore. To improve the cooling effect of sintered red ore and prevent dust leakage and cooling air overflow, water-sealed annular coolers are often used. The upper and lower sealed water troughs of the water-sealed annular cooler rotate synchronously with the annular cooler's rotating body, and rotate relative to the stationary upper and lower sealed water troughs, forming an upper-lower dynamic hydraulic seal system. This type of sealing system has an inherent flaw: the cooling air can cause sintered ore dust to overflow into the water trough. After long-term operation, dust particles accumulate, grow, and solidify at the bottom of the water trough. Once they form agglomerates, they are extremely difficult to remove. This can easily cause the water trough to curl, causing interference and "scratching" with the water trough, resulting in long-term equipment downtime and affecting the long-term stable operation of the feed line.

[0003] There are two types of dredging methods for existing upper sealed water tank dredging devices. One is to directly scrape the silt in the upper sealed water tank using a scraper bucket and other structures, and the other is to extract the silt in the upper sealed water tank by suction. Among them, the direct scraping dredging method requires a more complex structure and cannot effectively dredge the bottom and sides of the water tank. When the rotating body of the annular cooler deviates or the body is deformed, it is very easy to interfere with the movement of the scraper bucket and other structures. Therefore, suction is often used to dredge the upper sealed water tank.

[0004] The sludge in the upper sealed water tank is usually discharged by self-priming using the siphon effect principle. The siphon effect is not strengthened, the suction capacity is limited, and the cleaning effect of the silted and compacted silt is poor. In addition, the upper sealed water tank cannot be replenished with water during the silt removal process, and the sealing effect of the upper sealed water tank is difficult to guarantee. In addition, the ability to reuse the discharged turbid water is poor, and resources are seriously wasted. Summary of the Invention

[0005] In order to solve the technical problems in the above-mentioned background technology that the existing upper sealed water tank uses a siphon effect to discharge silt, which has poor cleaning effect on silted and compacted silt materials and easily affects the sealing effect of the upper sealed water tank, the present invention provides a ring cooler system with silt removal function and a silt removal method.

[0006] The technical solutions of the present invention are as follows: The present invention provides an annular cooler system with a dredging function, comprising: a rotary body rotatably arranged on a frame, an upper sealed water trough mechanism and a lower sealed water trough mechanism being respectively provided on the circumference sides of the upper and lower ends of the rotary body, a dredging mechanism being fixedly installed on the frame, the dredging mechanism being connected to the inner ring upper sealed water trough and the outer ring upper sealed water trough of the upper sealed water trough mechanism; the dredging mechanism comprising a suction pipe, the suction pipe being used to suck out the compacted silt deposited material in the upper sealed water trough mechanism, the suction pipe being connected to a sewage pipe, the sewage pipe being connected to a water supply main pipe through a connecting pipe, and the connecting pipe The through pipe is used to transport water to the sewage pipe to trigger the siphon effect. The water supply main is connected to the inner ring upper sealed water tank and the outer ring upper sealed water tank through the water supply branch pipe. The setting of the water supply main can, on the one hand, maintain the water level height in the corresponding inner ring upper sealed water tank / outer ring upper sealed water tank to maintain the sealing stability of the water sealing system; on the other hand, the impact force of the water flow can be used to break, stir and lift the dust accumulated at the bottom of the water tank to assist the suction work of the suction pipe, thereby facilitating the dredging work of the upper sealed water tank mechanism.

[0007] Preferably, the suction pipe is a hose, and the inlet diameter of the suction pipe is smaller than its outlet diameter, so as to gradually change the flow rate and movement direction of the water flow inside the suction pipe, thereby utilizing the Venturi effect to increase the water speed near the inlet, enhance the adsorption effect at the inlet, and achieve the agglomeration capture and rapid absorption of dust, compacted small pieces, sintered ore particles and turbid water. In addition, the setting of the hose structure has high flexibility, which can avoid scratches caused by the deviation of the rotating body 3 and the interference of movement with the sealing groove, effectively improving the safety of use and ensuring the effectiveness of the water supply seal.

[0008] Preferably, the suction pipe is connected to the sewage pipe through a water flow acceleration pipe, and a number of spirally arranged adjustment plates are fixed on the inner wall of the water flow acceleration pipe to change the flow direction of the turbid water in the water flow acceleration pipe, so that the water flows in a rotating manner along a spiral path, thereby generating a vortex effect of water. The rotational kinetic energy generated by the vortex effect is used to increase the axial kinetic energy of the turbid water, thereby increasing the water flow rate for a second time, further enhancing the suction force at the inlet of the suction pipe, and realizing the agglomeration capture and rapid absorption of dust, compacted small pieces, mineral particles and turbid water, thereby improving the cleaning effect of dust and particles in turbid water.

[0009] Preferably, a side of the regulating plate that contacts the water flow is provided with a guide arc surface to guide the water flow.

The corresponding control valves can be used to control the opening and closing of the corresponding pipelines as needed to meet different work requirements, such as constructing siphon reaction, water supply, water flow impact, etc.

[0011] Preferably, the sewage pipe is connected to a turbid water receiving bucket, which is connected to the sedimentation tank through a turbid water diversion pipe, a turbid water discharge pipe, and a turbid water water delivery pipe in sequence to transport the turbid water to the sedimentation tank for sedimentation treatment, so as to facilitate subsequent reuse.

[0012] Preferably, the sedimentation tank includes a first-level sedimentation tank, a second-level sedimentation tank, a third-level sedimentation tank and a clean water tank which are arranged in sequence. The first-level sedimentation tank is connected to the turbid water supply pipe, and the clean water tank is connected to the water replenishment main pipe. The dust and water in the turbid water are gradually separated, which effectively improves the treatment effect of the turbid water. The clean water tank can temporarily store the clean water to facilitate the subsequent construction of the siphon effect and the water replenishment work.

[0013] Preferably, the first-stage sedimentation tank, the second-stage sedimentation tank and the third-stage sedimentation tank are connected with sludge conveying pipes for extracting the sludge into the mixer for recycling and re-pelletizing and granulation. The clean water tank is connected with a water supply pipe for replenishing clean water into the clean water tank to ensure the stability of the water level in the clean water tank.

[0014] The present invention provides a dredging method, comprising: Close the third control valve, open the first control valve, the second control valve, the fourth control valve and the water supply pump in sequence, and the clean water in the clean water tank flows into the sewage pipe through the water supply main pipe and the connecting pipe in sequence; When water flows in the turbid water delivery pipe, the third control valve is opened and the second control valve is closed. The water flow in the sewage pipe generates a siphon effect under the action of gravitational potential energy. The turbid water in the inner ring upper sealed water tank and the outer ring upper sealed water tank is sucked into the sewage pipe by the suction pipe and discharged into the turbid water receiving hopper, so that dust, compacted small pieces, mineral particles and turbid water are agglomerated and captured and quickly absorbed, and then transported to the sedimentation tank. While utilizing the siphon effect to realize automatic dredging of the upper sealed water tank, synchronous water replenishment of the upper sealed water tank is realized, thereby ensuring the reliable operation of the water sealing system. In addition, the impact force of water is utilized to break, stir and lift the dust agglomerates deposited at the bottom of the water tank, thereby enhancing the dredging effect. After the dredging work of the inner ring upper sealed water tank and the outer ring upper sealed water tank is completed, the first control valve, the water supply pump and the fourth control valve are closed in sequence. While the siphon effect is used to realize the automatic dredging of the upper sealed water tank, the synchronous water supply of the upper sealed water tank is realized, ensuring the reliable operation of the water sealing system. At the same time, the impact force of water is used to break up, stir and lift the dust plate clumps deposited at the bottom of the water tank, thereby enhancing the dredging effect.

[0015] Preferably, the turbid water undergoes multi-stage sedimentation in the sedimentation tank, and the resulting clean water flows into the clean water tank for temporary storage, so as to facilitate the subsequent construction of the siphon effect and the implementation of water replenishment.

[0016] It can be seen from the above technical solutions that the advantages of the present invention are: 1. The sewage pipe is connected to the water supply pipe through a connecting pipe. The connecting pipe is used to supply water to the sewage pipe to trigger the siphon effect. The water supply pipe is connected to the inner ring upper sealed water tank and the outer ring upper sealed water tank through a water supply branch pipe. The setting of the water supply pipe can, on the one hand, maintain the water level height in the corresponding inner ring upper sealed water tank / outer ring upper sealed water tank and maintain the sealing stability of the water sealing system; on the other hand, the impact force of the water flow can be used to break, stir and lift the dust accumulated at the bottom of the water tank, so as to assist the suction work of the suction pipe and facilitate the dredging work of the upper sealed water tank mechanism.

[0017] 2. The suction pipe is a hose, and the inlet diameter of the suction pipe is smaller than its outlet diameter, so as to gradually change the flow rate and movement direction of the water flow inside the suction pipe, thereby utilizing the Venturi effect to increase the water speed near the inlet, enhance the adsorption effect at the inlet, and achieve the agglomeration capture and rapid absorption of dust, compacted small pieces, sintered ore particles and turbid water. In addition, the setting of the hose structure has high flexibility, which can avoid scratches caused by the deviation of the rotating body 3 and the movement interference with the sealing groove, effectively improving the safety of use and ensuring the effectiveness of the water supply seal.

[0021] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0022] Example 1 In a typical embodiment of the present invention, Figures 1-6 As shown, a ring cooler system with a dredging function is proposed, including: a rotating body 3, a frame 9, an upper sealed water tank mechanism, a lower sealed water tank mechanism and a dredging mechanism 5. The rotating body 3 is rotatably set on the frame 9, and the upper sealed water tank mechanism and the lower sealed water tank mechanism are arranged on the circumferential sides of the upper and lower ends of the rotating body 3 to form the upper and lower water seals of the rotating body 3. The dredging mechanism 5 is fixedly installed on the frame 9 and is connected to the upper sealed water tank mechanism to be used for dredging work of the upper sealed water tank mechanism.

[0023] Specifically, the frame 9 is connected to the foundation of the annular cooler to provide physical support for the entire annular cooler. A support roller 1 is fixedly installed on the frame 9 to provide physical support for the rotating body 3 and rotate relative to the rotating body 3.

[0024] The lower sealed water tank mechanism includes an inner ring lower sealed water tank 2, an outer ring lower sealed water tank 12 and a lower sealed water tank water dividing plate 11. The lower sealed water tank water dividing plate 11 is used to be inserted into the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12, that is, the lower sealed water tank water dividing plate 11 divides the interior of the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12 into two parts. The inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12 are fixedly arranged on the frame 9 by welding or the like as a whole. The inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12 are combined into an upper The lower sealed water trough water diversion plate 11 is fixed on the outer wall of the rotating body 3 by welding, and the lower sealed water trough water diversion plate 11 is arranged in the circumferential direction. The lower sealed water trough water diversion plate 11 is used to perform synchronous rotational motion with the rotating body 3. The lower sealed water trough water diversion plate 11 cooperates with the inner ring lower sealed water trough 2 and the outer ring lower sealed water trough 12 to perform relative motion. When working, the middle and lower part of the lower sealed water trough water diversion plate 11 is inserted into the sealing water in the inner ring lower sealed water trough 2 and the outer ring lower sealed water trough 12 to form a lower water seal.

[0025] In this embodiment, a plurality of high-pressure air holes are installed at the bottom of the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12, and the high-pressure air holes are connected to the high-pressure air source. At the same time, a sewage outlet is opened at the bottom of the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12 and a sewage control valve is installed. When sewage needs to be discharged, high-pressure airflow can be used to impact the compacted silt material and disturb the water flow, so that the compacted silt material no longer accumulates together and is finally discharged outward through the sewage outlet to realize the dredging work of the lower sealed water tank mechanism. A turbid water receiving hopper 13 for receiving turbid water is provided below the sewage outlet. The lower sealed water tank mechanism can use the water replenishment main pipe 511 to achieve water replenishment, thereby ensuring liquid sealing.

[0026] The upper sealed water tank mechanism includes an inner ring upper sealed water tank 4, an outer ring upper sealed water tank 8 and an upper sealed water tank water dividing plate 7. The inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 are integrally combined into an annular groove structure with an upper opening. The upper sealed water tank water dividing plate 7 is inserted into the inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8. That is, the upper sealed water tank water dividing plate 7 is used to separate the interior of the inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 into two parts. The inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 are integrally fixed by welding or the like. It is fixed on the outer wall of the rotating body 3, and the upper sealed water trough water distribution plate 7 is fixedly set on the frame 9 by welding, and the upper sealed water trough water distribution plate 7 is arranged in the circumferential direction. The inner ring upper sealed water trough 4 and the outer ring upper sealed water trough 8 as a whole follow the rotating body 3 to perform synchronous rotation. The upper sealed water trough water distribution plate 7 cooperates with the inner ring upper sealed water trough 4 and the outer ring upper sealed water trough 8 to perform relative movement. The middle and lower parts of the upper sealed water trough water distribution plate 7 are inserted into the sealed water in the inner ring upper sealed water trough 4 and the outer ring upper sealed water trough 8 to form an upper water seal.

[0027] In this embodiment, a fume hood 6 is fixedly mounted on the frame 9. The fume hood 6 is located directly above the rotating body 3 and is used to seal the upper end of the rotating body 3. The upper sealing water trough water distribution plate 7 is welded and fixedly mounted on the peripheral side of the outer wall of the lower end of the fume hood 6. The lower end of the fume hood 6 cooperates with the inner ring upper sealing water trough 4 and the outer ring upper sealing water trough 8 through the upper sealing water trough water distribution plate 7 to achieve water sealing.

[0028] There are two dredging mechanisms 5, which are relatively arranged on both sides of the rotating body 3. The dredging mechanisms 5 are fixedly installed on the frame 9. One of the dredging mechanisms 5 is used to connect with the inside of the sealed water tank 4 on the inner ring, and the other dredging mechanism 5 is used to connect with the inside of the sealed water tank 8 on the outer ring. Therefore, during the operation of the rotating body 3, the two relatively arranged dredging mechanisms 5 are used to synchronously dredge the inside of the sealed water tank 4 on the inner ring and the sealed water tank 8 on the outer ring, thereby improving the dredging efficiency and effect.

[0029] The desilting mechanism 5 can capture and quickly absorb and clean the accumulated and compacted dust and sintered ore particles inside the inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 based on the siphon effect and eddy current effect of water.

[0030] Specific as Figure 3 As shown, the silt removal mechanism 5 includes a suction pipe 51, a water flow acceleration pipe 52, a connecting flange 53, a sewage pipe 54, a first control valve 55, a second control valve 56, a connecting pipe 57, a third control valve 58, a water supply branch pipe 59, a fourth control valve 510, a water supply main pipe 511 and a water supply pump 512, wherein the suction pipe 51 is fixedly connected to the water flow acceleration pipe 52, the suction pipe 51 is a hose structure, and the suction pipe 51 is placed in the corresponding inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8, as shown in FIG. Figure 4As shown, the suction pipe 51 is a tapered tube structure, and the inlet diameter of the suction pipe 51 is smaller than its outlet diameter, so as to gradually change the flow rate and movement direction of the water flow inside the suction pipe 51, thereby utilizing the Venturi effect to increase the water speed near the inlet, enhance the adsorption effect at the inlet, and achieve the agglomeration capture and rapid absorption of dust, compacted small pieces, sintered ore particles and turbid water. In addition, the setting of the hose structure has high flexibility, which can avoid scratches caused by the deviation of the rotating body 3 and the interference of movement with the sealing groove, effectively improve the safety of use, and ensure the effectiveness of the water supply seal.

[0031] The water flow accelerating tube 52 is a steel pipe structure, and is connected to the sewage pipe 54 through a connecting flange 53. A plurality of adjusting plates 513 are welded and fixed on the inner wall of the water flow accelerating tube 52. Figure 5 As shown, all the regulating plates 513 are spirally arranged along the axial direction of the water flow accelerating tube 52 to change the flow direction of the turbid water in the water flow accelerating tube 52, so that the water flows along the spiral path, thereby generating a vortex effect of the water. The rotational kinetic energy generated by the vortex effect is used to increase the axial kinetic energy of the turbid water, thereby increasing the flow rate of the water for a second time, so as to further enhance the suction force at the inlet of the suction pipe 51, thereby achieving the agglomeration capture and rapid absorption of dust, compacted small pieces, mineral particles and turbid water, and improving the cleaning effect of dust and particles in the turbid water; Figure 6 As shown, a side surface of the regulating plate 513 for contacting the water flow is provided with a guide arc surface 5131 , and the guide arc surface 5131 is an arc-shaped surface to guide the water flow.

[0032] The sewage pipe 54 is arranged vertically and is parallel to the water flow acceleration pipe 52. The sewage pipe 54 is used to transport turbid water outward. The first control valve 55 is installed on the sewage pipe 54 to control the on-off of the sewage pipe 54. The sewage pipe 54 is also connected to the connecting pipe 57. The interior of the sewage pipe 54 is connected to the interior of the connecting pipe 57. The sewage pipe 54 is connected to the water supply main 511 through the connecting pipe 57. The second control valve 56 is installed on the connecting pipe 57 to control the on-off between the water supply main 511 and the sewage pipe 54. The connecting pipe 57 is used to transport water into the sewage pipe 54 to construct Triggering the siphon effect; the water supply main pipe 511 is also connected to the water supply branch pipe 59, the water outlet end of the water supply branch pipe 59 extends into the corresponding inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8, so as to supply water to the corresponding inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8. On the one hand, it can maintain the water level height in the corresponding inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8 and maintain the sealing stability of the water sealing system; on the other hand, the impact force of the water flow can be used to quickly crush, stir and lift the dust deposited at the bottom of the water tank, so as to facilitate the dredging work of the upper sealed water tank mechanism.

[0033] The third control valve 58 is installed on the water supply branch pipe 59 to control the on-off of the water supply branch pipe 59; the water supply main pipe 511 is connected to the water source through the water supply pump 512, and the water supply pump 512 is used to provide the kinetic energy required for water delivery. The fourth control valve 510 is installed on the water supply main pipe 511 to control the on-off of the water supply main pipe 511, and at the same time prevent water backflow when the water supply pump 512 is not in operation, which may cause water seal failure of the inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8.

[0034] In this embodiment, the water replenishment volume of the water replenishment branch pipe 59 is the same as the turbid water output of the corresponding sewage pipe 54, so as to maintain the stability of the water level in the inner ring upper sealed water tank 4 / outer ring upper sealed water tank 8, thereby ensuring the sealing stability of the water sealing system.

[0035] The ring cooler system also includes a turbid water treatment circulation mechanism to treat and recycle turbid water to reduce costs. Figure 1 and Figure 2 As shown, the turbid water treatment circulation mechanism includes a turbid water receiving hopper 13, a turbid water diversion pipe 14, a turbid water discharge pipe 15, a turbid water water delivery pipe 16 and a sedimentation tank 17, wherein the upper end opening of the turbid water receiving hopper 13 is larger than the lower end opening thereof, and a plurality of turbid water receiving hoppers 13 are provided, and the plurality of turbid water receiving hoppers 13 are correspondingly arranged below the sewage outlets of the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12, and the turbid water receiving hoppers 13 are respectively connected to a sewage discharge pipe 54, so as to receive the turbid water directly discharged from the bottom of the inner ring lower sealed water tank 2 and the outer ring lower sealed water tank 12, as well as the turbid water discharged through the sewage discharge pipe 54 of the dredging mechanism 5; The lower end of the turbid water receiving hopper 13 is connected to the turbid water drainage pipe 15 through the turbid water diversion pipe 14, so as to transport the collected turbid water to the turbid water drainage pipe 15 through the turbid water diversion pipe 14. The turbid water drainage pipe 15 is an annular pipe so as to be connected with all the turbid water diversion pipes 14. The turbid water drainage pipe 15 is connected to the turbid water water supply pipe 16, and is connected to the sedimentation tank 17 through the turbid water water supply pipe 16, so that the turbid water is transported to the sedimentation tank 17 for sedimentation treatment. The sedimentation tank 17 is also connected to the water supply main pipe 511, so as to transport the treated water through the water supply main pipe 511 and reuse it to reduce costs.

[0036] The sedimentation tank 17 is a multi-stage treatment structure, which can achieve gradient separation of dust and water in the turbid water step by step. Figure 2As shown, the sedimentation tank 17 includes a primary sedimentation tank 171, a secondary sedimentation tank 172, a tertiary sedimentation tank 173 and a clean water tank 174. The primary sedimentation tank 171, the secondary sedimentation tank 172, the tertiary sedimentation tank 173 and the clean water tank 174 are arranged in a quadrilateral to improve space utilization. The primary sedimentation tank 171 is connected to the turbid water water pipe 16 and the secondary sedimentation tank 172 respectively, and the tertiary sedimentation tank 173 is connected to the secondary sedimentation tank 172 and the clean water tank 174 respectively, so that the turbid water is processed step by step through the primary sedimentation tank 171, the secondary sedimentation tank 172 and the tertiary sedimentation tank 173 in sequence to form clean water, and the clean water enters the clean water tank 174 for temporary storage.

[0037] The first-stage sedimentation bin 171, the second-stage sedimentation bin 172, and the third-stage sedimentation bin 173 are also connected to a sludge conveying pipe 18 for extracting the sludge into a mixer for recycling and re-pelletizing and granulation; the clean water bin 174 is connected to a water supply pipe 19 and a water supply main pipe 511. The water supply pipe 19 is used to add clean water to the clean water bin 174 to ensure that the water level in the clean water bin 174 is stable. The water supply main pipe 511 is used to transport the clean water in the clean water bin 174 to the upper sealed water tank mechanism for reuse.

[0038] Example 2 In a typical embodiment of the present invention, a dredging method is proposed, which uses the annular cooler system in Example 1. The dredging method specifically includes: Close the third control valve 58, open the first control valve 55, the second control valve 56, the fourth control valve 510 and the water supply pump 512 in sequence, and the clean water in the clean water tank 174 flows into the sewage pipe 54 through the water supply main 511 and the connecting pipe 57 in sequence to build a triggered siphon effect. The water in the inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 is sucked into the sewage pipe 54 by the corresponding suction pipe 51 and transported to the turbid water receiving bucket 13 through the sewage pipe 54. When water flows in the turbid water delivery pipe 16, the water in the inner ring upper sealed water tank 4 and the outer ring upper sealed water tank 8 is sucked into the sewage pipe 54 by the corresponding suction pipe 51. After that, the third control valve 58 is opened and the second control valve 56 is closed. The clean water in the water supply main 511 is supplied to the corresponding inner ring upper sealed water tank 4 and outer ring upper sealed water tank 8 through the water supply branch pipe 59. While supplying water, the impact of the water flow is used to break up and stir the dust accumulated at the bottom of the water tank and drive it to rise. The water flow in the sewage pipe 54 produces a siphon effect under the action of gravitational potential energy, and continuously draws and discharges silt from the suction pipe 51 without the action of external energy drive. The turbid water in the sewage pipe 54 is sequentially transported to the primary sedimentation tank 171 of the sedimentation tank 17 through the turbid water receiving hopper 13, the turbid water diversion pipe 14, the turbid water discharge pipe 15, and the turbid water delivery pipe 16. The turbid water flows through the primary sedimentation tank 171, the secondary sedimentation tank 172, and the tertiary sedimentation tank 173 in sequence to achieve multi-stage sedimentation. The resulting clean water finally flows into the clean water tank 174 for temporary storage to be used for subsequent water replenishment and the construction of the siphon reaction triggering work; After the dredging work of the inner ring sealed water tank 4 and the outer ring sealed water tank 8 is completed, the first control valve 55, the water supply pump 512 and the fourth control valve 510 are closed in sequence to ensure the reliable and stable water level in the inner ring sealed water tank 4 and the outer ring sealed water tank 8.

[0039] When it is necessary to dredge the inner ring sealed water trough 2 and the outer ring sealed water trough 12, high-pressure airflow is used to impact the compacted silt and disturb the water flow, so that the compacted silt no longer accumulates together, and then the sewage outlets at the bottom of the inner ring sealed water trough 2 and the outer ring sealed water trough 12 are opened, and finally discharged outward through the sewage outlets. The sewage outlets discharge the turbid water into the turbid water receiving hopper 13, and the turbid water is transported to the first-level sedimentation bin 171 of the sedimentation tank 17 through the turbid water receiving hopper 13, the turbid water diversion pipe 14, the turbid water discharge pipe 15, and the turbid water water supply pipe 16 in turn. The turbid water flows through the first-level sedimentation bin 171, the second-level sedimentation bin 172 and the third-level sedimentation bin 173 in turn to achieve multi-stage sedimentation, and the clean water formed finally flows into the clean water bin 174 for temporary storage for subsequent water replenishment and the work of triggering the siphon reaction. While utilizing the siphon effect to achieve automatic dredging of the upper sealed water tank, the system also achieves synchronous water replenishment of the upper sealed water tank, ensuring the reliable operation of the water sealing system. At the same time, the impact force of water is utilized to break up, stir and lift the dust clumps deposited at the bottom of the water tank, thereby enhancing the dredging effect.
