Description

Technical Field

[0001] This invention relates to the field of lake and reservoir sludge treatment technology, specifically to a device for in-situ ecological living water algae control in lakes and reservoirs. Background Technology

[0002] Untreated or incompletely treated domestic sewage contains large amounts of pollutants such as phosphorus-containing detergents and excrement. Some industrial wastewater also contains high concentrations of nitrogen and phosphorus compounds. When this sewage is discharged into lakes and reservoirs, it causes eutrophication, leading to algae blooms. Dead or dormant algae fall to the bottom and form sludge, which further increases pollution and contaminates the lake water. To prevent algae blooms at the bottom of lakes, it is necessary to use a floating platform to wash and treat the sludge. This process includes steps such as agitation and washing, settling and separation, and suction treatment. Specifically, it can be divided into the following steps: Step 1, Disturbance and elution: Submerge the elution chamber to the bottom of the water, covering a small area that needs to be treated. The elution chamber will physically disturb the sludge inside the chamber by means of mechanical disturbance head rotation, high-pressure water jet flushing, or aeration, so that the sludge is resuspended in the water. Step 2, let it stand and separate. After the disturbance is stopped, let the water stand still. According to physical principles, heavy, clean coarse particles of silt will quickly settle back to the bottom of the lake, while light fine particles that have adsorbed pollutants such as nitrogen, phosphorus, and organic matter will continue to be suspended in the water, forming a high concentration of wash water. Step 3, suction treatment: the water pumps on the floating platform will suck the pollutant-rich wash water from step 2 into the ship's treatment system, and then the clean water will flow directly back into the lake. However, existing sludge treatment equipment has some shortcomings, such as: The above-mentioned disturbance, settling, and suction steps need to be completed step by step. Each step should be performed sequentially, without overlap or simultaneous cross-operation. This results in a slower sludge treatment speed and lower treatment efficiency. Summary of the Invention

[0003] In order to overcome the shortcomings of the prior art, the present invention provides a device for in-situ ecological algae control in lakes and reservoirs, which solves the problem that the disturbance step, settling step and suction step cannot be carried out simultaneously and crosswise, resulting in low sludge treatment efficiency.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A device for in-situ ecological algae control in lakes and reservoirs includes a purification platform and an integrated washing and absorption machine; The purification table is equipped with an upgraded retractor, a gas-liquid pump, a water pump, a high-pressure reaction tank, a stirring device, an air compressor, a spray pipe, and a sterilizer, all connected in series. The washing and absorption integrated machine includes a Y-axis support rail, a sealing frame and a stirrer. The Y-axis support rail is fixedly connected to the connecting seat. The rear end of the connecting seat is fixedly connected to the purification table. The upper end of the connecting seat is fixedly connected to a connecting end. The water pump is indirectly connected to the upper end of the connecting end. The sealing frame is hollow inside. There are two sealing frames arranged side by side. One sealing frame is fixedly connected to the Y-direction support rail and the connecting seat. The inside of the sealing frame is connected to the connecting seat. The other sealing frame moves along the length of the Y-direction support rail and is inserted into the Y-direction support rail. When the sealing frame slides to the bottom of the connecting seat, it is connected to the connecting seat. The connecting seat is equipped with a swing-type intermittent sealing assembly. When the movable sealing frame enters or leaves directly below the connecting seat, the swing-type intermittent sealing assembly controls the communication channels between the two sealing frames and the connecting seat to open alternately. Both sealed frames are fixedly connected with X-direction built-in rails along their length. The direction of the X-direction built-in rails is perpendicular to the direction of the Y-direction support rails. Two inner slides are movably installed between the two X-direction built-in rails. An agitator is installed between the two inner slides. The agitator agitates the lake bottom sludge and sewage in the sealed frames. With the above technical solution, when the washing and absorption integrated machine is in operation, the movable sealing frame slides back and forth on the Y-direction support rail. When it enters directly below the connecting seat, the two sealing frames are aligned side by side. The swing-type intermittent sealing component automatically opens the communication channel between the sealing frame and the connecting seat, while closing the communication channel of the fixedly installed sealing frame. When the movable sealing frame is moved away, the two sealing frames are staggered. The swing-type intermittent sealing component automatically closes the communication channel between the sealing frame and the connecting seat, while opening the communication channel of the fixedly installed sealing frame, thereby realizing the function of the two sealing frames alternately communicating with the water pump. Furthermore, when the two sealing frames are connected side by side, the inner slide carries the agitator through two X-axis built-in tracks from one sealing frame to the other. After entering one of the sealing frames, its agitator blades rotate and disturb the bottom mud, causing the pollutants to be suspended in the water, thus performing the disturbance elution step. Meanwhile, the sludge and wastewater in another sealed frame enters a static state and performs a static separation step; Suspended light wastewater sludge is pumped to the purification platform by a water pump through the connecting seat and connecting end. It then passes through the gas-liquid pump for energy enhancement, high-temperature and high-pressure digestion in the high-pressure reaction tank, physical washing by the stirring device, and finally the treated water is returned to the lake by the jet pipe for suction treatment. Throughout the process, the Y-axis movement of the movable sealing frame, the X-axis movement of the inner slide, the rotational disturbance of the agitator, and the alternating opening and closing of the suction channel work together to achieve synchronous cyclic operation. While one sealing frame is being agitated, the other sealing frame is in a static suction state. The two work synchronously and alternately without waiting for each other, eliminating the intermittent gaps in the operation of a single sealing frame and significantly improving sludge treatment efficiency.

[0005] Preferably, a first water absorption channel is provided along the length direction of the inner wall of the upper half of the sealing frame, and water absorption holes are provided in a rectangular array on the side of the first water absorption channel. A second water absorption channel is provided at the upper end of the sealing frame, and the lower end of the second water absorption channel is connected to the first water absorption channel. Within the fixedly installed sealed frame, the second water suction channel is connected to the connector. When the movable sealing frame slides to directly below the connecting seat, the second water suction channel connects into the connecting seat. The above technical solution improves the specific structure of the water circuit connection between the sealing frame and the connecting seat. After the stirring and turbulence in the sealing frame are completed and after static stratification, the light sewage sludge mixture suspended in the middle and upper layers enters the connecting seat through the suction hole, the first suction channel and the second suction channel under the negative pressure of the water pump.

[0006] Preferably, the oscillating intermittent sealing assembly includes a protrusion, a push rod, a V-shaped swing rod, and a torsion spring. The push rod and the V-shaped swing rod rotate coaxially on the connecting seat, and a torsion spring is fixedly connected between the pivot of the push rod and the V-shaped swing rod and the connecting seat. The V-shaped swing rod is located inside the connecting seat. When the V-shaped swing rod rotates, its two ends alternately block the second water absorption channels of the two sealing frames. The push rod is located below the connecting seat. The protrusion is located on the upper side of the movable sealing frame. When the movable sealing frame moves to the bottom of the connecting seat, the protrusion pushes the push rod to rotate. With the above technical solution, when the movable sealing frame moves along the Y-axis support track directly below the connecting seat, the protrusion fixed on the upper side of the movable sealing frame moves accordingly. The protrusion pushes the push rod to rotate, and the push rod drives the V-shaped swing arm to rotate synchronously. The torsion spring stores elastic potential energy, and the second water suction channel of the movable sealing frame, which was originally blocked, opens. At the same time, the other end rotates to the outlet of the second water suction channel of the fixed sealing frame to block it. When the movable sealing frame moves away from directly below the connecting seat, the protrusion disengages from the push rod, the elastic potential energy stored in the torsion spring is released, driving the push rod and V-shaped swing arm to rotate in the opposite direction to reset, so that the two ends of the V-shaped swing arm return to their original positions, that is, blocking the second water intake channel of the movable sealing frame, while opening the second water intake channel of the fixed sealing frame. In summary, the reciprocating motion of the movable sealing frame controls the swing of the V-shaped lever, thereby achieving the alternating opening and closing of the second water suction channel of the two sealing frames. The switching timing precisely corresponds to the position of the movable sealing frame.

[0007] Preferably, the agitator includes a first roller, an axially sliding arc-shaped seat, a second roller, a circumferentially rotating arc-shaped ring, an arc-shaped seat connecting rod, an arc-shaped ring connecting rod, and a stirring blade. The axially sliding arc-shaped seats are linearly arranged and movably fitted outside the X-direction internal track. The vertical cross-section of the axially sliding arc-shaped seats is arc-shaped. The first roller rotates within the axially sliding arc-shaped seats via a rotating shaft. The first roller rolls on the X-direction internal track. An arc-shaped seat connecting rod is fixedly connected between a row of axially sliding arc-shaped seats. Two inner slides are fixedly connected to the two ends of the arc-shaped seat connecting rod, respectively. Each axially sliding arc-shaped seat is fitted with a circumferentially rotating arc-shaped ring. A second roller rotates in an arc-shaped array on the inner side of the circumferentially rotating arc-shaped ring. The second roller rolls on the outer side of the axially sliding arc-shaped seat. The vertical cross-section of the circumferentially rotating arc-shaped ring is arc-shaped. Arc-shaped ring connecting rods are fixedly connected between a row of circumferentially rotating arc-shaped rings. A stirring blade is fixedly connected in an arc-shaped array on the side of each circumferentially rotating arc-shaped ring. Through the above technical solution, the axial sliding arc seat and the circumferential rotating arc ring are coaxially connected. Both have circular arc cross sections and a notch in the lower half. This shape can avoid the connection between the X-direction built-in track and the sealing frame, ensuring that the entire agitator can move between the two X-direction built-in tracks. The circumferential rotating arc ring can rotate freely around the central axis of the axial sliding arc seat. When the circumferential rotating arc ring rotates, the agitator blades move in a circular motion, thereby rotating and agitating the lake bottom sludge and sewage in the sealing frame. In summary, the entire mixer can slide axially and the circumferential rotating arc ring can rotate circumferentially. The axial and circumferential movements are independent of each other, yet they complement each other without interfering with one another.

[0008] Preferably, a first power component is installed inside the inner slide, which drives a row of circumferentially rotating arc rings and arc ring connecting rods to rotate. The first power assembly includes a first waterproof motor, a drive gear, and a semi-arc driven gear ring. The first waterproof motor is fixedly connected to the inner slide. The output shaft of the first waterproof motor rotates and passes into the inner slide, and then is fixedly connected to the drive gear. The drive gear meshes with the semi-arc driven gear ring. The semi-arc driven gear ring is fixedly connected to the end of the arc ring connecting rod. Furthermore, the center of the semi-arc driven gear ring and the center of the circumferentially rotating arc ring are on the same straight line. Through the above technical solution, the first waterproof motor is powered on and drives the active gear to rotate in both directions. The active gear drives the semi-arc passive gear ring to rotate in both directions through inter-tooth meshing, which in turn drives the arc ring connecting rod and the circumferential rotating arc ring to rotate in both directions.

[0009] Preferably, a second power assembly is installed inside both the inner slide and the movable sealing frame, and the second power assembly drives the inner slide or the sealing frame to move. The above technical solution improves the power source for the movement of the inner slide or sealing frame.

[0010] Preferably, a sealer is installed in the end of each of the two sealing frames that are close to each other. The sealer opens when the two sealing frames are side by side and connected, and seals the ends of the sealing frames after the two sealing frames are staggered. The sealer includes a limit rod, a sealing door, and a spring. The upper and lower ends of the sealing door slide within the lower end of the sealing frame and the Y-axis support track, respectively. The thickness of the sealing door is greater than the distance between the two sealing frames. When the two sealing frames are aligned side by side, the sealing frame pushes open the sealing door. A spring is fixedly connected between the sealing door and the Y-direction support rail. A limit rod is fixedly connected inside the Y-direction support rail. The limit rod is arranged side by side with the Y-direction support rail and moves through the sealing door. The limit rod is located inside the spring. With the above technical solution, the sealing door can only slide back and forth along the Y-direction support track and cannot deflect or disengage. When the two sealing frames come together and are aligned side by side, the sealing frame pushes open the sealing door on the other sealing frame. That is, the two sealing frames push open each other's sealing doors, and both sealing doors are pushed open, so that the inner slide and agitator can pass through one sealing frame into another sealing frame without obstruction along the X-direction built-in track. As the movable sealing frame gradually separates from the fixed sealing frame, the compressed spring releases its elasticity, pushing the sealing door back to its initial position, resealing the opening ends of their respective sealing frames, and sealing the sealing frames to prevent the stirred-up sludge from leaking out. The limit rod prevents the spring from bending during extension and retraction.

[0011] The beneficial effects of this invention are as follows: In summary, this device coordinates the Y-axis movement of the movable sealing frame, the X-axis movement of the inner slide, the rotational disturbance and X-axis movement of the agitator, and the alternating opening and closing of the second suction channel to achieve synchronous cyclic operation. While one sealing frame is being agitated, the other sealing frame is in a static suction state. That is, agitation and static operation alternate between the two sealing frames. Regardless of which sealing frame is static, suction can be performed after static operation. Therefore, the agitation and static operation overlap and work synchronously without waiting for each other, eliminating the intermittent gaps in the operation of a single sealing frame and significantly improving sludge treatment efficiency.

Detailed Implementation

[0023] The following will refer to the attached reference. Figures 1 to 10 The various embodiments of the present invention will be described in detail. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0024] Appendix Figure 7 The side wall of the inner slide 17 is dissected and some parts of the agitator 18 are removed to demonstrate the structural cooperation principle of the agitator 18, the inner slide 17 and the first power assembly 2201. Appendix Figure 8 The structure and working principle of the built-in X-axis track 16, inner slide 17, and second power component 23 are shown in the figure.

[0025] As attached Figure 1 - Appendix Figure 9 As shown, a device for in-situ ecological algae control in lakes and reservoirs includes a purification platform and an integrated washing and absorption machine. Cleanroom stand: See attached document Figure 1 and attached Figure 10 The purification table is equipped with an upgraded retractor 1, a gas-liquid pump 2, a water pump 3, a high-pressure reaction tank 5, a stirring device 6, an air compressor 7, a spray pipe 8, and a sterilizer 24. Upgraded Retractor 1: See Appendix Figure 1 and attached Figure 10The upgraded retractor 1 is rotatably installed on the clean table. The upgraded retractor 1 has a water suction pipe 4 wound inside. When the upgraded retractor 1 is rotated in the forward and reverse directions, the water suction pipe 4 is wound or unwound accordingly. One end of the water suction pipe 4 is moved through the bottom of the clean table and then fixedly connected to the water suction pump head 9. The water suction pump head 9 sucks water, and the other end of the water suction pipe 4 is connected to the water pump 3. Water pump 3: See appendix Figure 1 and attached Figure 10 The inlet of the water pump 3 is connected to the water pumping pipe 4, and the outlet of the water pump 3 is connected to the liquid inlet of the high-pressure reaction tank 5. The water pump 3 pumps the mixture of water and mud from the water pumping pipe 4 and delivers the mixture of water and mud into the high-pressure reaction tank 5. Gas-liquid pump 2: See appendix Figure 1 and attached Figure 10 The outlet of the gas-liquid pump 2 is connected to the pipeline between the water pump 3 and the high-pressure reaction tank 5 through a pipeline. The inlet of the gas-liquid pump 2 is connected to the sterilizer 24 and the air compressor 7. The gas-liquid pump 2 is an existing gas-liquid mixing pump that generates compressed air. The compressed air is used to increase the suction of the sludge-sewage mixture. By injecting high-pressure compressed air into the pipeline, a gas-water mixture with a lower density is formed, thereby increasing the conveying capacity. High-pressure reaction vessel 5: See appendix Figure 1 and attached Figure 10 The inlet of the high-pressure reactor 5 is connected to the gas-liquid pump 2 and the water pump 3 through a pipe, and the outlet of the high-pressure reactor 5 is connected to the stirring device 6 through a pipe. By placing the sludge in a high-temperature and high-pressure environment, the high-pressure reactor 5 can decompose toxic and harmful substances in the sludge, such as persistent organic compounds such as polycyclic aromatic hydrocarbons, and achieve harmlessness. At the same time, it can also destroy the cell walls of microorganisms in the sludge and release the organic matter therein, preparing for subsequent steps of converting into fuel or improving dewatering. Stirring device 6: See appendix Figure 1 and attached Figure 10 The inlet of the stirring device 6 is connected to the high-pressure reaction tank 5 through a pipe, and the outlet of the stirring device 6 is connected to the spray pipe 8. The spray pipe 8 has spray nozzles arranged in a straight array on its side. The treated lake water is sprayed out from the spray nozzles of the spray pipe 8. The stirring device 6 generates a high-speed water flow to form strong turbulence, which separates the pollutant particles deposited on the surface of the bottom sediment from the heavier inorganic gravel, forming a physical washing. Air compressor 7: See appendix Figure 1 and attached Figure 10 The air compressor 7's outlet is connected to the sterilizer 24's inlet via a pipe. The sterilizer 24's inlet is connected to the gas-liquid pump 2 via a pipe. The gas generated by the air compressor 7 is discharged into the gas-liquid pump 2 through the sterilizer 24's advanced oxidizing gas and combines with the water to form a micro-nano gas bag.

[0026] Washing and Absorption All-in-One Machine: See Appendix Figure 1 - Appendix Figure 9 The washing and absorbing integrated machine includes a Y-axis support rail 13, a sealing frame 11, and a stirrer 18; Y-axis support track 13: See appendix Figure 1 and attached Figure 3 The Y-axis support rail 13 is fixedly connected inside the connecting seat 12; Connector 12: See Appendix Figure 1 The rear end of the connector 12 is fixedly connected to the purification table, and the upper end of the connector 12 is fixedly connected to the connector end 10. The water suction pump head 9 is inserted into the upper end of the connector end 10 to suck up the sewage in the connector end 10. Sealing frame 11: See appendix Figure 1 - Appendix Figure 4 The interior of the sealing frame 11 is hollow and is used to cover a certain area of ​​the lake bottom. The upper half of the inner wall of the sealing frame 11 is provided with a first water absorption channel 20 along the length direction. The side of the first water absorption channel 20 is provided with a rectangular array of water absorption holes 19. The sludge and sewage inside the sealing frame 11 are absorbed through the densely distributed water absorption holes 19. The water absorption holes 19 are located in the upper half of the sealing frame 11 to limit the absorption of floating sludge and not absorb the silt that sinks to the bottom. The sludge and sewage covered by the sealing frame 11 are sequentially sucked into the first water absorption channel 20 through the water absorption holes 19. See appendix Figure 4 The upper end of the sealing frame 11 is provided with a second water suction channel 21, and the lower end of the second water suction channel 21 is connected to the first water suction channel 20, so that sludge and sewage are sucked into the second water suction channel 21. There are two sealing frames 11, see appendix. Figure 4 and attached Figure 6 One is fixedly installed while the other is slidably installed. The specific installation method is as follows: One of the sealing frames 11 is fixedly connected to the Y-direction support rail 13 and the connecting seat 12. The second water suction channel 21 is directly connected to the connecting seat 12. The sludge and sewage mixture in the sealing frame 11 flows into the connecting seat 12 from the water suction hole 19, the first water suction channel 20 and the second water suction channel 21, and is then sucked up by the water suction pump head 9. Another sealing frame 11 moves along the length of the Y-direction support track 13 and is inserted into the Y-direction support track 13. When the sealing frame 11 slides directly below the connecting seat 12, the second water suction channel 21 connects into the connecting seat 12. Then, the sludge and sewage mixture in the sealing frame 11 flows into the connecting seat 12 from the water suction hole 19, the first water suction channel 20 and the second water suction channel 21, and is then sucked up by the water suction pump head 9. After the sealing frame 11 leaves directly below the connecting seat 12, the second water suction channel 21 is offset from the connecting seat 12 and no longer sucks up the sludge and sewage mixture in the sealing frame 11.

[0027] A swing-type intermittent sealing assembly 15 is installed inside the connecting seat 12, see attached. Figure 4 Appendix Figure 6 and attached Figure 9 ; The oscillating intermittent sealing assembly 15 includes a protrusion 1501, a push rod 1502, a V-shaped swing rod 1503, and a torsion spring 1504. The push rod 1502 and the V-shaped swing rod 1503 rotate coaxially on the connecting seat 12, and the torsion spring 1504 is fixedly connected between the pivot of the push rod 1502 and the V-shaped swing rod 1503 and the connecting seat 12. The V-shaped swing rod 1503 is located inside the connecting seat 12. When the V-shaped swing rod 1503 rotates, its two ends alternately block the second water absorption channel 21 of the two sealing frames 11. The push rod 1502 is located below the connecting seat 12. The protrusion 1501 is provided on the upper side of the movable sealing frame 11. When the movable sealing frame 11 moves to the lower side of the connecting seat 12, the protrusion 1501 pushes the push rod 1502 to rotate. In summary: When the movable sealing frame 11 moves directly below the connecting seat 12, the protrusion 1501 pushes the push rod 1502 to rotate, and the push rod 1502 drives the V-shaped swing rod 1503 to rotate, so that one end of the V-shaped swing rod 1503 leaves the second water suction channel 21 of the movable sealing frame 11, that is, the second water suction channel 21 is opened, and at the same time, the other end of the V-shaped swing rod 1503 blocks the second water suction channel 21 of the fixed sealing frame 11, that is, the second water suction channel 21 is closed. Similarly, when the movable sealing frame 11 moves away from directly below the connecting seat 12, the protrusion 1501 moves away from the push rod 1502, and the torsion spring 1504 pushes the push rod 1502 and the V-shaped swing rod 1503 to rotate back to their original positions in the opposite direction. This causes one end of the V-shaped swing rod 1503 to block the second water absorption channel 21 of the movable sealing frame 11, i.e., close the second water absorption channel 21. At the same time, the other end of the V-shaped swing rod 1503 moves away from the second water absorption channel 21 of the fixed sealing frame 11, i.e., open the second water absorption channel 21.

[0028] See appendix Figure 3 - Appendix Figure 5 Appendix Figure 7 and attached Figure 8 An X-direction built-in track 16 is fixedly connected to each of the two sealing frames 11 along its length. The direction of the X-direction built-in track 16 is perpendicular to the direction of the Y-direction support track 13. Two inner slides 17 are movably installed between the two X-direction built-in tracks 16. The ends of the two sealing frames 11 that are close to each other are open structures to ensure that the inner slides 17 can move between the X-direction built-in tracks 16 in the two sealing frames 11.

[0029] See appendix Figure 4 Appendix Figure 5 and attached Figure 7 An agitator 18 is installed between the two inner slides 17. The agitator 18 agitates the lake bottom sludge and sewage in the sealing frame 11. The agitator 18 includes a first roller 1801, an axially sliding arc-shaped seat 1802, a second roller 1803, a circumferentially rotating arc-shaped ring 1804, an arc-shaped seat connecting rod 1805, an arc-shaped ring connecting rod 1806, and a stirring blade 1807. The axially sliding arc-shaped seat 1802 is linearly arranged and movably sleeved outside the X-direction internal track 16. The vertical cross-section of the axially sliding arc-shaped seat 1802 is arc-shaped, that is, a notch is provided at the lower end, so that the axially sliding arc-shaped seat 1802 will not be obstructed by the X-direction internal track 16 and the sealing frame 1. The connection part of 1 is blocked. A first roller 1801 rotates through a rotating shaft inside the axial sliding arc seat 1802. The first roller 1801 rolls on the X-direction built-in track 16 to reduce the movement resistance of the axial sliding arc seat 1802. An arc seat connecting rod 1805 is fixedly connected between a row of axial sliding arc seats 1802. The arc seat connecting rod 1805 fixes a row of axial sliding arc seats 1802 together. Two inner slides 17 are fixedly connected to the two ends of the arc seat connecting rod 1805 respectively. Each axially sliding arc-shaped seat 1802 is surrounded by a circumferentially rotating arc-shaped ring 1804. A second roller 1803 rotates within an inner arc-shaped array on the inner side of the circumferentially rotating arc-shaped ring 1804. The second roller 1803 rolls on the outer side of the axially sliding arc-shaped seat 1802 to reduce friction between the circumferentially rotating arc-shaped ring 1804 and the axially sliding arc-shaped seat 1802. Similarly, the vertical cross-section of the circumferentially rotating arc-shaped ring 1804 is also arc-shaped, with the lower half... The notch is provided so that the circumferential rotating arc ring 1804 will not be blocked by the connection between the X-direction built-in track 16 and the sealing frame 11 when it moves. Arc ring connecting rods 1806 are fixedly connected between a row of circumferential rotating arc rings 1804, so that a row of circumferential rotating arc rings 1804 can rotate at the same time. Each circumferential rotating arc ring 1804 has an arc array of fixedly connected stirring blades 1807 on its side. When the stirring blades 1807 rotate, they stir the sewage and sludge at the bottom of the lake. As described above, the agitator 18 can move between two sealing frames 11. When one of the sealing frames 11 moves to the area to be cleaned at the bottom of the lake, the agitator 18 moves into that sealing frame 11 to stir the bottom of the lake and agitate the sludge and sewage. When the agitator 18 moves out, the sludge and sewage can stand still in the sealing frame 11. Then the suction hole 19 sucks up the sludge and sewage mixture. When the agitator 18 moves out, it moves into the other sealing frame 11, and the above steps are repeated.

[0030] See appendix Figure 5 and attached Figure 7A first power assembly 22 is installed inside the inner slide 17. The first power assembly 22 drives a row of circumferentially rotating arc rings 1804 and arc ring connecting rods 1806 to rotate. The first power assembly 22 includes a first waterproof motor 2201, a drive gear 2202, and a semi-arc passive gear ring 2203. The first waterproof motor 2201 is fixedly connected to the inner slide 17. The output shaft of the first waterproof motor 2201 rotates and passes into the inner slide 17, and then is fixedly connected to the drive gear 2202. The drive gear 2202 meshes with the semi-arc passive gear ring 2203. The semi-arc passive gear ring 2203 is fixedly connected to the end of the arc ring connecting rod 1806. Furthermore, the center of the semi-arc passive gear ring 2203 is on the same straight line as the center of the circumferentially rotating arc ring 1804, so that when the semi-arc passive gear ring 2203 rotates, it drives the circumferentially rotating arc ring 1804 to rotate through the arc ring connecting rod 1806.

[0031] As attached Figure 6 and attached Figure 8 As shown, a second power assembly 23 is installed in both the inner slide 17 and the movable sealing frame 11. The second power assembly 23 drives the inner slide 17 or the sealing frame 11 to move. The second power assembly 23 includes a second waterproof motor 2301 and a third roller 2302, with the output shaft of the second waterproof motor 2301 fixedly connected to the third roller 2302; The second waterproof motor 2301 is fixedly connected to the inner slide 17 in the second power assembly 23 installed inside the inner slide 17, and the third roller 2302 rotates in the X-direction built-in track 16. The second power assembly 23 is installed in the movable sealing frame 11, the second waterproof motor 2301 is fixedly connected in the sealing frame 11, and the third roller 2302 rotates in the Y-direction support rail 13; The second power assembly 23 works as follows: The output shaft of the second waterproof motor 2301 drives the third roller 2302 to rotate in the X-direction built-in track 16. By means of the rolling contact between the third roller 2302 and the X-direction built-in track 16, the stirrer 18 is pulled to travel between the two sealing frames 11. The second power assembly 23, installed in the movable sealing frame 11, drives the third roller 2302 to rotate in the Y-direction support rail 13, thereby driving the entire movable sealing frame 11 to slide back and forth in the Y direction, so that it can be moved out or in from directly below the connecting seat 12.

[0032] As attached Figure 1 and attached Figure 3As shown, a sealer 14 is installed in the two sealing frames 11 at their close ends. When the two sealing frames 11 are aligned and connected, the sealer 14 opens. When the two sealing frames 11 are staggered, the sealer 14 seals the ends of the sealing frames 11 to ensure that the frames 11 are sealed. The sealer 14 includes a limit rod 1401, a sealing door 1402 and a spring 1403. The upper and lower ends of the sealing door 1402 slide in the lower end of the sealing frame 11 and the Y-direction support track 13, respectively. The thickness of the sealing door 1402 is greater than the distance between the two sealing frames 11. When the two sealing frames 11 are aligned and connected, the sealing frame 11 pushes open the sealing door 1402. A spring 1403 is fixedly connected between the sealing door 1402 and the Y-direction support rail 13. When the two sealing frames 11 are misaligned, the spring 1403 pushes back the sealing door 1402, so that the sealing door 1402 blocks the opening of the sealing frame 11. A limit rod 1401 is fixedly connected inside the Y-direction support rail 13. The limit rod 1401 is arranged side by side with the Y-direction support rail 13 and moves through the sealing door 1402. The limit rod 1401 is located inside the spring 1403 and is used to support the spring 1403. The working principle of the sealer 14 is as follows: when the two sealing frames 11 are close to each other, the sealing door 1402 is pushed by the opposite sealing frame 11 and is forced to slide away from the sealing frame 11, compressing the spring 1403, thereby opening the end of the sealing frame 11, allowing the inner slide 17 and its carried agitator 18 to pass through the opening from one side of the sealing frame 11 and enter the other side of the sealing frame 11. When the movable sealing frame 11 moves in the opposite direction and separates from the fixed sealing frame 11, the spring 1403 releases its elastic potential energy, pushing the sealing door 1402 to slide back into position, re-blocking the opening end of the sealing frame 11, and preventing the sludge and sewage inside the frame from leaking out.

[0033] The working principle of this device is as follows: In the initial state, the two sealing frames 11 are aligned side by side. Inside the movable sealing frame 11, the first power component 22 drives the agitator 18 to stir the lake bottom sewage and sludge. After stirring, the second power component 23 drives the inner slide 17 and the agitator 18 to move along the X-direction built-in track 16 into the X-direction built-in track 16 inside the fixed sealing frame 11, and starts to stir the lake bottom sludge and sewage inside the fixed sealing frame 11. The sludge and sewage inside the movable sealing frame 11 begin to settle. After the sludge and sewage at the bottom of the lake are stirred in the fixed sealing frame 11, the movable sealing frame 11 is sucked out, and the inner slide 17 and the agitator 18 return to the movable sealing frame 11. At this time, the fixed sealing frame 11 is allowed to stand and separate into layers. The second power unit 23 drives the movable sealing frame 11 to move forward, the agitator 18 stirs the new lake bottom area in the movable sealing frame 11, and the fixed sealing frame 11 is sucked up. Then the entire purification table moves forward, and the purification table moves the fixed sealing frame 11 forward. At the same time, the movable sealing frame 11 moves backward relative to the connecting seat 12. Then the position of the first sealing frame 11 relative to the lake bottom remains unchanged, so that the two sealing frames 11 are aligned side by side again. Start repeating the above process in a loop; The suction process is as follows: the water pump 3 transports the mud-water mixture from the bottom of the lake to the high-pressure reaction tank 5 through the water pump head 9 and the water pipe 4. At the same time, the gas-liquid pump 2 combines the high-grade oxidizing gas produced by the reaction of the gas discharged from the air compressor 7 through the sterilizer 24 with the water to form micro-nano gas bags, which are also transported to the high-pressure reaction tank 5 for reaction. The treated mud-water gas-liquid mixture then enters the stirring device 6 to fully react the mud-water gas-liquid mixture. Finally, it is sprayed onto the water surface through the spray pipe 8.
