Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically to an integrated wastewater purification and reuse equipment for aquatic product processing. Background Technology

[0002] The aquatic product processing industry generates a large amount of wastewater during processes such as raw material cleaning, cutting, cooking, and cooling. Currently, the wastewater treatment equipment for aquatic product processing mainly adopts a combination of pretreatment and advanced treatment processes. The pretreatment stage mainly relies on screens, sedimentation tanks, and ordinary filters to remove suspended solids, while the advanced treatment stage decomposes organic matter through aeration oxidation. Because the flow rate of wastewater from aquatic product processing changes dynamically with production conditions, but the number of filter plates and the number of aeration pipes in existing filters are fixed, when the water volume is too large, the filter load is overloaded, resulting in incomplete removal of suspended solids and a surge in pressure in subsequent treatment units. When the water volume is too small, the water flow velocity in the filter is too slow, the filter media is prone to caking, and the aeration efficiency of the aeration tank is low, resulting in energy waste. Therefore, an integrated wastewater purification and reuse equipment for aquatic product processing is proposed, which can dynamically adjust the filtration and aeration capacity according to the water flow rate to ensure treatment effect and operational stability. Summary of the Invention

[0003] To address the problems in existing technologies, this invention provides an integrated wastewater purification and reuse device for aquatic product processing, which can dynamically adjust filtration and aeration capabilities according to the water flow rate, ensuring treatment effectiveness and operational stability.

[0004] The technical solution adopted by this invention to solve its technical problem is an integrated aquatic product processing wastewater purification and reuse equipment, including an inlet tank. The inlet tank is equipped with a mechanical bar screen. Several sets of floating valve assemblies distributed from top to bottom are connected in the inlet tank. The floating valve assemblies are all connected to inclined tube sedimentation tanks. The inclined tube sedimentation tanks are all connected to aeration tanks. Inclined tube assemblies are installed in the inclined tube sedimentation tanks. A first sealing assembly is installed below the inclined tube assemblies. An aeration composite treatment assembly is installed in the aeration tanks. A second sealing assembly is installed below the aeration composite treatment assembly. The floating valve assemblies are driven by the first sealing assembly and the second sealing assembly through a transmission structure to adjust the sealing range of the first sealing assembly and the second sealing assembly.

[0005] Specifically, the inclined tube assembly includes a first mounting frame fixedly connected to the inside of the inclined tube sedimentation chamber. The first mounting frame is provided with several sets of inclined filter tubes. The first sealing assembly initially seals the bottom of the inclined filter tubes. Several sets of conical sludge collection hoppers are connected to the bottom of the inclined tube sedimentation chamber. The outside of the conical sludge collection hoppers is connected to a sewage discharge pipe.

[0006] Specifically, the aeration composite treatment component includes a second mounting frame fixedly connected to the inside of the aeration chamber. The second mounting frame has several spaced filter shells, each containing ceramic filter media. Aeration pipes are provided between the filter shells, and several air outlets are provided below the aeration pipes. The outer side of the aeration pipes is fixedly connected to the adjacent filter shells through a sealing plate. In the initial state, the second sealing component seals the bottom of the filter shells and aeration pipes.

[0007] Specifically, the upper part of the inclined tube sedimentation tank is connected to the bottom of the aeration tank through several sets of water outlet pipes.

[0008] Specifically, the first sealing component includes a first rotating shaft horizontally disposed below the inclined filter tube, a first winding roller mounted on the first rotating shaft, a first flexible pad wound on the first winding roller, and one end of the first flexible pad being fixedly connected to the inner wall of the inclined tube sedimentation chamber. Both ends of the first rotating shaft are rotatably connected to the first slider. Both ends of the first rotating shaft are provided with a first movable seat that slides with the first slider. A first spring is connected between the first movable seat and the first slider. A first screw is internally threaded onto the first movable seat. One end of the first screw is rotatably connected to the inner wall of the inclined tube sedimentation chamber, and the other end of the first screw passes through the inclined tube sedimentation chamber and is fixedly connected to the first worm gear.

[0009] Specifically, the second sealing component includes a second rotating shaft horizontally disposed below the filter shell and the aeration pipe, a second winding roller is mounted on the second rotating shaft, a second flexible pad is wound on the second winding roller, and one end of the second flexible pad is fixedly connected to the inner wall of the aeration chamber. Both ends of the second rotating shaft are rotatably connected to the second slider. Both ends of the second rotating shaft are provided with a second movable seat that slides with the second slider. A second spring is connected between the second movable seat and the second slider. A second screw is internally threaded onto the second movable seat. One end of the second screw is rotatably connected to the inner wall of the aeration chamber, and the other end of the second screw passes through the aeration chamber and is fixedly connected to the second worm gear.

[0010] Specifically, the floating valve assembly includes an inlet connected to the inclined tube sedimentation tank. A groove is provided on one side of the inlet and set in the inner wall of the inlet pool. A third slider is slidably connected in the groove. A sealing plate for slidingly closing the inlet is fixedly connected to one side of the third slider. A floating plate is fixedly connected to the side of the sealing plate away from the slider. The grooves of several sets of sealing plates are not in the same vertical direction.

[0011] Specifically, the transmission structure includes several sets of horizontally arranged drive shafts. One end of the drive shaft passes through the inlet pool and is fixedly connected to a drive gear. A rack that meshes with the drive gear is fixedly connected to one side of the sealing plate. A worm gear that meshes with the first worm wheel and the second worm wheel is fixedly connected to the drive shaft. The drive shaft is fixedly connected to the outside of the inclined tube sedimentation chamber and the aeration chamber through several sets of rotating seats.

[0012] Specifically, the inlet tank is equipped with an inlet pipe on the side away from the inclined tube sedimentation chamber; the aeration chamber is equipped with an outlet pipe on the upper part away from the inclined tube sedimentation chamber.

[0013] The beneficial effects of this invention are: (1) The integrated wastewater purification and reuse equipment for aquatic product processing described in this invention can dynamically adjust the number of effective inclined filter tubes in the inclined tube sedimentation chamber and the number of effective filter shells and aeration tube groups in the aeration chamber according to the real-time changes in the water volume of aquatic product processing wastewater through the coordinated action of the floating valve assembly, transmission structure and the first and second sealing components. When the water volume surges, multiple inclined tube sedimentation chambers and aeration chambers are put into operation simultaneously to avoid incomplete removal of suspended solids due to overload of a single unit. When the water volume decreases, only a small number of treatment units are kept in operation to prevent filter media from caking due to water flow stagnation and energy waste caused by redundant aeration. This solves the problem that the fixed processing capacity of traditional equipment cannot adapt to dynamic working conditions.

[0014] (2) The integrated wastewater purification and reuse equipment for aquatic product processing described in this invention, under low water volume conditions, only a small number of inclined filter pipes and aeration pipes are turned on to concentrate water pressure to increase water flow rate in order to ensure treatment efficiency, while reducing the ineffective energy consumption of aeration pumps; under high water volume conditions, multiple treatment units are parallel and diverted to avoid energy consumption loss due to the need for additional pressurization due to overload of a single unit. Compared with existing fixed structure equipment, it effectively reduces energy consumption and significantly improves long-term economic efficiency.

[0015] (3) The integrated wastewater purification and reuse equipment for aquatic product processing described in this invention uses a floating valve assembly with a staggered sliding groove design to gradually open the water inlet channel from top to bottom, disperse the instantaneous water pressure in the pipeline, avoid the sealing wear or pipeline leakage caused by high pressure impact of a single water inlet, and at the same time reduce the impact damage of water pressure fluctuations on the inclined filter tube and ceramic filter material, and extend the replacement cycle of the inclined filter tube and ceramic filter material.

[0016] (4) The integrated wastewater purification and reuse equipment for aquatic product processing described in this invention integrates pretreatment, sedimentation, aeration and filtration functions into one unit, eliminating the need for additional multi-unit separate equipment and reducing the floor space occupied. At the same time, the dynamic adjustment process is automatically triggered by the buoyancy of the water level, eliminating the need for manual intervention to adjust the number of filter plates or the opening status of the aeration pipe. Only the sludge in the conical sludge collection hopper needs to be cleaned periodically through the sewage discharge pipe, reducing the complexity of operation and maintenance and meeting the actual needs of continuous production and low operation and maintenance costs in aquatic product processing.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] In order to dynamically adjust the filtration and aeration capacity according to the water flow rate, and to ensure treatment effect and operational stability, as one embodiment of the present invention, such as Figure 1 , Figure 2As shown, the integrated wastewater purification and reuse equipment for aquatic product processing according to the present invention includes an inlet tank 1, a mechanical bar screen 2 installed in the inlet tank 1, and several sets of floating valve assemblies distributed from top to bottom connected in the inlet tank 1. The floating valve assemblies are all connected to inclined tube sedimentation tanks 3, and the inclined tube sedimentation tanks 3 are all connected to aeration tanks 4. Inclined tube assemblies are installed in the inclined tube sedimentation tanks 3, and a first sealing assembly is installed below the inclined tube assemblies. An aeration composite treatment assembly is installed in the aeration tanks 4, and a second sealing assembly is installed below the aeration composite treatment assembly. The floating valve assemblies are driven by the first sealing assembly and the second sealing assembly through a transmission structure to adjust the sealing range of the first sealing assembly and the second sealing assembly.

[0021] When in use, wastewater from aquatic product processing is introduced into the inlet pool 1 through pipelines. When the wastewater flows through the mechanical screen 2 in the inlet pool 1, the mechanical screen 2 will intercept large particulate impurities such as raw material residues and lumpy suspended solids in the wastewater, effectively reducing the risk of blockage of subsequent inclined tube components and aeration composite treatment components. As sewage is continuously injected, the water level in the inlet tank 1 gradually rises. When the water volume reaches the preset threshold, the bottom floating valve assembly is opened by the buoyancy of the water level, and the sewage flows into the bottom inclined tube sedimentation tank 3. If the water volume continues to increase, the upper floating valve assembly will be opened sequentially from bottom to top by the buoyancy, and the corresponding inclined tube sedimentation tank 3 will be put into the treatment process simultaneously. The inlet channel is opened in stages by the water level change to avoid local pressure concentration caused by a single channel bearing excessive water flow, and to initially disperse the water pressure in the pipeline, ensuring that sewage continuously enters the treatment system and ensuring the continuity and stability of sewage treatment. In the initial state, the first sealing component completely seals the bottom of the inclined tube component. When the water level rises, the floating valve component drives the first sealing component to work through the transmission structure, gradually expanding the effective filtration area of ​​the inclined tube component. It can also prevent the suspended solids from not settling sufficiently due to excessive water flow velocity in a single channel, thus ensuring solid-liquid separation efficiency. Wastewater that has undergone solid-liquid separation in inclined tube sedimentation tank 3 flows into aeration tank 4. The displacement of the floating valve assembly will synchronously drive the second closed assembly through the transmission structure, gradually expanding the effective treatment range of the aeration composite treatment assembly and increasing the number of aeration channels. The opening of multiple channels makes the water flow resistance match the high water pressure in the pipeline, and regulates the water flow rate to a suitable range. This avoids insufficient aeration time and incomplete decomposition of organic matter due to excessively fast water flow, and also prevents redundant aeration due to excessively slow flow. It reduces the ineffective energy consumption of the aeration pump and solves the problems of low aeration efficiency and energy waste when the water volume of traditional aeration tank fluctuates. When the water level in the inlet tank 1 decreases due to reduced water intake or accelerated treatment, the floating valve assembly sinks synchronously with the drop in water level. The transmission structure then reverses its action. On one hand, it drives the first sealing assembly to reset, re-covering part of the inclined tube assembly, reducing the effective filtration area of ​​the inclined tube assembly, and keeping only a small number of sedimentation channels in operation. By concentrating limited water pressure, it increases the flow rate of water through the inclined tube assembly. This allows the sediment in the inclined tube assembly to be discharged into the lower part of the inclined tube sedimentation chamber 3, and also reduces the long-term contact between idle inclined tubes and sewage, preventing the inclined tube assembly from becoming caked due to suspended solids. On the other hand, the transmission structure drives the second sealing assembly to reset, reducing the effective treatment capacity of the aeration composite treatment assembly, maintaining a small number of aeration channels in operation. By concentrating water pressure, it increases the flow rate of sewage through the ceramic filter media, preventing the filter media from becoming clogged due to water stagnation when the water volume is low. At the same time, it can further save energy by reducing the output power loss of the aeration pump. After being treated inside aeration chamber 4, the wastewater is finally discharged through the top of aeration chamber 4, completing the closed-loop treatment of wastewater purification and reuse.

[0022] To extend the service life of the inclined filter tube 6, for example, such as Figure 1 , Figure 6 , Figure 7 , Figure 8 , Figure 9 As shown, the present invention also includes an inclined tube assembly comprising a first mounting frame 5 fixedly connected to the inner side of the inclined tube sedimentation chamber 3, a plurality of inclined filter tubes 6 being provided in the first mounting frame 5, the first sealing assembly initially sealing the lower part of the inclined filter tubes 6, a plurality of conical sludge collection hoppers 7 being connected to the lower part of the inclined tube sedimentation chamber 3, and a sewage discharge pipe 8 being connected to the outer side of the conical sludge collection hoppers 7.

[0023] During use, after the sewage enters the inclined tube sedimentation chamber 3, the sewage flows through the inclined filter tube 6 to achieve solid-liquid separation, and the sludge falls into the conical sludge collection hopper 7 under the action of gravity; when the sludge in the conical sludge collection hopper 7 accumulates to the preset amount, the sewage discharge pipe 8 valve is opened to discharge it. When the influent flow rate is low, the water level in the influent tank 1 rises slowly. The water in the influent tank 1 only opens the bottom floating valve assembly, which drives the first closed assembly through the transmission structure to open a small range of inclined filter tubes 6 for filtration. This ensures the flow rate of sewage in the inclined tube assembly, reduces the caking of filter media caused by the growth of microorganisms or the attachment of suspended solids on the inner wall of the inclined filter tubes 6, and extends the service life of the inclined filter tubes 6. By using only a small number of inclined filter tubes 6, the overall energy consumption of the equipment is reduced, and there is no need to maintain the water flow power for the idle inclined filter tubes 6. Similarly, when the inlet water volume of pool 1 is large and the water level rises rapidly, all floating valve components open, and the transmission structure drives the first sealing component to open completely. All inclined filter tubes 6 are put into filtration, maximizing the total filtration area. This can quickly divert a large amount of sewage under high water pressure, avoiding overload of a single set of filter tubes that could cause blockage or rupture. At the same time, it disperses the water pressure in the sedimentation tank, preventing leakage from the sedimentation tank wall due to excessive pressure, and ensuring that the equipment can still stably meet the standards under high water volume.

[0024] To facilitate adjustment of the treatment area of ​​the aeration pipe 11 and the filter shell 10 according to the influent flow rate, for example, such as Figure 7 , Figure 10 , Figure 11 As shown, the present invention also includes an aeration composite treatment component comprising a second mounting frame 9 fixedly connected to the inner side of the aeration chamber 4, a plurality of spaced filter shells 10 disposed within the second mounting frame 9, ceramic filter media placed within the filter shells 10, an aeration pipe 11 disposed between the plurality of filter shells 10, a plurality of air outlets 12 disposed below the aeration pipes 11, and the outer side of the aeration pipes 11 being fixedly connected to adjacent filter shells 10 via sealing plates 13; the second sealing component initially seals the lower part of the plurality of filter shells 10 and the aeration pipes 11.

[0025] During use, wastewater flows into aeration chamber 4 after solid-liquid separation in inclined tube sedimentation chamber 3. The opening range of the second sealing component is synchronously controlled by the floating valve component through the transmission structure. When the influent flow rate is low, the floating valve assembly moves upward only slightly. Relying on the transmission structure, the second sealing assembly opens only part of the filter shell 10 and aeration pipe 11. The ceramic filter media inside the filter shell 10 can intercept fine suspended solids in the sewage that have not been settled, effectively avoiding filter media clogging caused by stagnant water flow under low flow rates. At the same time, a small number of aeration pipes 11 are activated simultaneously, and the air outlets 12 release aeration bubbles evenly, which come into full contact with the sewage, significantly improving the efficiency of organic matter oxidation and decomposition, and avoiding energy waste caused by redundant aeration. In addition, the sealing plate 13 seals the filter shell 10 and aeration pipe 11, preventing water from overflowing upwards without being filtered by the filter shell 10, ensuring the effectiveness of the treatment process. When the influent volume increases, the floating valve assembly moves upward more significantly, and the transmission structure synchronously drives the second sealing assembly to expand its opening range, prompting more filter shells 10 and aeration pipes 11 to be put into operation. With the total treatment area increasing synchronously, on the one hand, it can effectively divert a large amount of sewage under high water pressure, avoiding damage to a single filter shell 10 or aeration pipe 11 due to overload; on the other hand, the parallel operation of multiple filter shells 10 can further balance the water pressure in the pipeline, reduce the damage of water flow impact to the inner wall of the aeration chamber 4, and ensure that the equipment can still operate stably under high water volume conditions. When the water level in the inlet tank 1 rises further, more floating valve components open in sequence, and the corresponding number of inclined tube sedimentation chambers 3 and aeration chambers 4 are opened in conjunction, thereby realizing the function of automatically adjusting the usage of the treatment unit according to the water level in the inlet tank 1, adapting to different water intake conditions.

[0026] For example, such as Figure 7 As shown, the present invention also includes a set of several sets of outlet pipes 14 connecting the upper part of the inclined tube sedimentation tank 3 to the bottom of the aeration tank 4.

[0027] During use, the clarified wastewater after solid-liquid separation in the inclined tube sedimentation chamber 3 is ensured to enter the aeration chamber 4 through the outlet pipe 14, so as to avoid the unsettled sludge being mixed into the subsequent treatment process with the water flow and to ensure the quality of the influent for aeration treatment.

[0028] For example, such as Figure 7 , Figure 8 , Figure 9 As shown, the present invention also includes a first sealing component comprising a first rotating shaft 15 horizontally disposed below the inclined filter tube 6, a first winding roller 16 mounted on the first rotating shaft 15, a first flexible pad 17 wound on the first winding roller 16, and one end of the first flexible pad 17 being fixedly connected to the inner wall of the inclined tube sedimentation chamber 3. Both ends of the first rotating shaft 15 are rotatably connected to the first slider 18. Both ends of the first rotating shaft 15 are provided with a first movable seat 19 that slides with the first slider 18. A first spring 20 is connected between the first movable seat 19 and the first slider 18. A first screw 21 is internally threaded to the first movable seat 19. One end of the first screw 21 is rotatably connected to the inner wall of the inclined tube sedimentation tank 3. The other end of the first screw 21 passes through the inclined tube sedimentation tank 3 and is fixedly connected to the first worm gear 22.

[0029] In use, the corresponding floating valve assembly moves upward and drives the first worm gear 22 to rotate slowly through the transmission structure. The first worm gear 22 drives the first screw 21 to rotate, causing the first moving seat 19 to move along the screw direction. The first slider 18 slides in the first moving seat 19, and the first winding roller 16 moves synchronously with the first slider 18 while rolling, gradually winding the first flexible pad 17 onto the first winding roller 16. If the amount of wastewater from aquatic product processing is small, the first winding roller 16 rolls a short distance, opening only a small number of filter channels of the inclined filter tube 6. This concentrates the limited water pressure and increases the flow rate of water through the inclined filter tube 6, which not only pushes a small amount of settled sludge in the inclined filter tube 6 to fall quickly into the conical sludge collection hopper 7, avoiding the retention of suspended solids and the formation of caking, but also eliminates the need to maintain water flow power for idle filter tubes, significantly saving equipment energy consumption. When the sewage volume is moderate, the water level in the inlet tank 1 rises, the corresponding floating valve assembly moves upward a greater distance, the first winding roller 16 rolls a greater distance, and continues to wind the first flexible pad 17. The number of open inclined filter tubes 6 increases simultaneously. This adjustment can balance the water pressure in the pipeline and keep the water flow rate within the appropriate range, ensuring that suspended solids settle sufficiently and avoiding excessive load on a single filter tube, thus ensuring stable solid-liquid separation efficiency. When the sewage volume surges and the water level in the inlet tank 1 reaches a high level, all floating valve components open, opening the corresponding number of inclined tube sedimentation chambers 3. The first moving seat 19 moves to its limit position, the first flexible pad 17 is fully released, and all inclined filter tubes 6 are put into filtration. At this time, the filtration area is maximized, which can quickly divert a large amount of sewage under high water pressure, effectively disperse the pressure load in the inclined tube sedimentation chamber 3, realize the automatic adjustment of the treatment unit usage according to the water level in the inlet tank 1, adapt to different inlet water conditions, and ensure stable operation of the equipment under high water volume conditions.

[0030] When the amount of sewage decreases, the water level in the inlet pool 1 drops, the floating valve assembly sinks, the transmission structure drives the first worm gear 22 to rotate in the opposite direction, the first screw 21 drives the first moving seat 19 to reset, the first spring 20 rebounds and pushes the first slider 18 to move, the first rotating shaft 15 rotates in the opposite direction and re-spreads the first flexible pad 17, reducing the effective filtration area of ​​the inclined filter tube 6. The first spring 20 drives the first slider 18, the first rotating shaft 15 and the first winding roller 16 to press against the lower part of the inclined filter tube 6, so that the first flexible pad 17 is in contact with the bottom of the filter tube, preventing unfiltered sewage from leaking from the gap of the inclined filter tube 6 and avoiding unsedimented sludge from mixing into subsequent processes.

[0031] For example, such as Figure 7 , Figure 10 , Figure 11 As shown, the present invention also includes a second sealing component comprising a second rotating shaft 23 horizontally disposed below the filter shell 10 and the aeration pipe 11, a second winding roller 24 mounted on the second rotating shaft 23, a second flexible pad 25 wound on the second winding roller 24, and one end of the second flexible pad 25 fixedly connected to the inner wall of the aeration chamber 4. Both ends of the second rotating shaft 23 are rotatably connected to the second slider 26. Both ends of the second rotating shaft 23 are provided with a second movable seat 27 that slides with the second slider 26. A second spring 28 is connected between the second movable seat 27 and the second slider 26. A second screw 29 is internally threaded to the second movable seat 27. One end of the second screw 29 is rotatably connected to the inner wall of the aeration chamber 4, and the other end of the second screw 29 passes through the aeration chamber 4 and is fixedly connected to the second worm gear 30.

[0032] When in use, when the amount of wastewater from aquatic product processing is small and the water level in the inlet pool 1 is low, only the bottom floating valve assembly is opened. The transmission structure drives the second worm gear 30 to rotate, and the second worm gear 30 drives the second screw 29 to rotate, causing the second moving seat 27 to move slightly along the screw direction. The second winding roller 24 rolls while moving with the second slider 26, gradually winding the second flexible pad 25 onto the second winding roller 24. A small amount of filter shell 10 and aeration pipe 11 are opened to concentrate the limited water pressure and ensure the flow rate of water through the ceramic filter material. This avoids water flow stagnation under low water volume, which can cause the filter material to become clogged. At the same time, a small amount of aeration pipe 11 concentrates aeration and fully contacts the wastewater, improving the efficiency of organic matter oxidation and decomposition, and avoiding energy waste caused by redundant aeration. The pre-compression of the second spring 28 always maintains the pressure between the second winding roller 24 and the bottom of the component, which facilitates the winding of the second flexible pad 25. When the sewage volume is moderate, the water level in the inlet tank 1 rises, more floating valve components open, the transmission structure drives the second moving seat 27 to move further, the second flexible pad 25 continues to wind, and the number of open filter shells 10 and aeration pipes 11 increases synchronously, so that the water flow rate is kept in the appropriate range, ensuring that the ceramic filter material fully intercepts fine suspended matter, and the aeration bubbles diffuse evenly, improving the synergistic effect of aeration and filtration. When the sewage volume surges and the water level in the inlet tank 1 reaches a high level, all floating valve components open, the transmission structure drives the second flexible pad 25 to be completely wrapped, and all filter shells 10 and aeration pipes 11 are put into operation. At this time, the total treatment area is maximized, which can quickly divert a large amount of sewage under high water pressure, effectively disperse the pressure load in the aeration chamber 4, and prevent the ceramic filter material of a single filter shell 10 from being damaged due to overload, or the aeration pipe 11 from being blocked by the air outlet 12 due to the impact of high-pressure water flow, thus ensuring stable operation of filtration and aeration under high water volume conditions. When the amount of sewage decreases, the water level in the inlet pool 1 drops, the floating valve assembly sinks, the transmission structure drives the second worm gear 30 to rotate in the opposite direction, the second screw 29 drives the second moving seat 27 to reset, the second rotating shaft 23 rotates in the opposite direction and re-spreads the second flexible pad 25, gradually closing part of the filter shell 10 and aeration pipe 11, and increasing the water flow rate by concentrating water pressure to ensure the continuity of the treatment effect.

[0033] For example, such as Figure 4 , Figure 5 As shown, the present invention also includes a floating valve assembly comprising an inlet communicating with the inclined tube sedimentation tank 3, a groove 31 provided on one side of the inlet and disposed on the inner wall of the inlet pool 1, a third slider slidably connected in the groove 31, a sealing plate 33 for slidingly closing the inlet fixedly connected on one side of the third slider, a floating plate 34 fixedly connected on the side of the sealing plate 33 away from the slider, and the grooves 31 of several sets of sealing plates 33 are not in the same vertical direction.

[0034] When in use, wastewater from aquatic product processing is injected into the inlet pool 1. As the amount of wastewater increases, the water level in the inlet pool 1 gradually rises. The floating plate 34 is lifted upward by buoyancy, which drives the sealing plate 33 at the lower position to move upward first. The inclined tube sedimentation tank 3 at the lower position opens the water inlet channel first, which can initially disperse the water pressure in the pipeline. If the sewage inflow increases and the water level continues to rise, the sealing plate 33 at the top will move upward and open sequentially as the water level rises. The corresponding inclined tube sedimentation tank 3 will be put into the treatment process in stages, so that the inflow channel can be expanded in stages. This can balance the pressure of the entire pipeline system, avoid overloading of a single inclined tube sedimentation tank 3, and ensure that sewage continuously and stably enters the treatment system, thus ensuring the continuity and efficiency of sewage treatment. When the aquatic product processing steps are adjusted, resulting in a reduction in the influent volume, the water level in the influent tank 1 gradually decreases. The floating plate 34 sinks synchronously with the liquid level, causing the sealing plate 33 to move down and reset, gradually closing the corresponding influent channels. First, the channels that are open at the top are closed, leaving only a small number of inclined tube sedimentation tanks 3 at the bottom to operate. This can concentrate the limited water pressure to increase the water flow rate, reduce the retention of sewage in the idle inclined tube sedimentation tanks 3, avoid filter media caking caused by suspended solids, and dynamically adapt the treatment unit according to the actual water volume, reducing the ineffective energy consumption of the equipment.

[0035] For example, such as Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 8 , Figure 10 As shown, the present invention also includes a transmission structure comprising several sets of horizontally arranged drive shafts 35. One end of the drive shaft 35 passes through the water inlet tank 1 and is fixedly connected to a drive gear 36. A rack 37 that meshes with the drive gear 36 is fixedly connected to one side of the sealing plate 33. A worm gear 38 that meshes with the first worm wheel 22 and the second worm wheel 30 is fixedly connected to the drive shaft 35. Several sets of rotating seats 39 are fixedly connected to the outer sides of the inclined tube sedimentation tank 3 and the aeration tank 4 respectively.

[0036] In use, when the sealing plate 33 of the floating valve assembly moves up and down with the water level, the rack 37 on one side of the sealing plate 33 moves synchronously. The rack 37 meshes with the drive gear 36, directly driving the drive shaft 35 to rotate. When the drive shaft 35 rotates, the worm gear 38 rotates synchronously. The worm gear 38 meshes with the first worm wheel 22 and the second worm wheel 30. When the water flow increases, the sealing plate 33 moves upward more, and the rack 37 drives the drive shaft 35 to rotate more. The worm gear 38 drives the first worm wheel 22 and the second worm wheel 30 to rotate more, thereby opening the first sealing component and the second sealing component to a larger extent. When the water flow decreases, the sealing plate 33 moves downward, the drive shaft 35 rotates in the opposite direction, and the worm gear 38 drives the first worm wheel 22 and the second worm wheel 30 to reset. The first sealing component and the second sealing component reduce their opening range. The whole process can dynamically adapt to changes in water flow, avoid overload or idleness of the treatment unit, and reduce energy waste while ensuring purification effect.

[0037] For example, such as Figure 1 , Figure 2 As shown, the present invention also includes an inlet pipe 40 on the side of the inlet tank 1 away from the inclined tube sedimentation tank 3; and an outlet pipe 32 on the upper part of the aeration tank 4 away from the inclined tube sedimentation tank 3.

[0038] In use, the inlet pipe 40 is located on the side of the inlet pool 1 away from the inclined tube sedimentation tank 3. After the sewage enters the inlet pool 1, it first flows through the mechanical screen 2 to intercept large impurities such as raw material residue and lumpy suspended solids, so as to avoid the untreated sewage directly impacting the inclined tube sedimentation tank 3 and protect the subsequent inclined tube components from being blocked. The outlet pipe 32 is located at the top of the aeration chamber 4, away from the sedimentation chamber, to prioritize the discharge of qualified clean water and prevent incompletely treated sewage or sludge from the bottom from mixing into the effluent flow, thus ensuring the quality of the effluent.

[0039] When in use, the wastewater from aquatic product processing is introduced into the equipment through the inlet pipe 40 on one side of the inlet pool 1. After the wastewater flows through the mechanical screen 2 in the inlet pool 1, it flows to the inlet corresponding to the floating valve assembly. The mechanical screen 2 intercepts large particulate impurities such as raw material residues and lumpy suspended solids in the wastewater, effectively reducing the risk of blockage in the subsequent inclined tube assembly and aeration composite treatment assembly. As sewage is continuously injected, the water level in the inlet tank 1 gradually rises. The floating plate 34 is driven by buoyancy to move the sealing plate 33 upwards in sequence, opening the inlet channels of the corresponding inclined tube sedimentation chamber 3 in stages. When the water volume decreases, the water level drops, and the sealing plate 33 sinks with the floating plate 34, gradually closing the inlet channels from top to bottom. This avoids the single channel carrying excessive water flow, which would cause local pressure concentration. It initially disperses the water pressure in the pipeline, ensuring that sewage continuously and stably enters the treatment system. At the same time, it dynamically adapts the treatment unit according to the water volume, reducing ineffective energy consumption. Wastewater flows into the inclined tube sedimentation chamber 3 through the open inlet channel and passes through the inclined filter tube 6 in the first mounting frame 5. When the water level rises, the floating valve assembly drives the first sealing assembly through the transmission structure to gradually wrap the first flexible pad 17 to expand the effective filtration area of ​​the inclined filter tube 6. When the water level drops, the first flexible pad 17 is re-spread, reducing the effective filtration area. Solid-liquid separation is achieved through the inclined filter tube 6, and the sludge falls into the conical sludge collection hopper 7 under gravity. When the water volume is high, all inclined filter tubes 6 are put into operation, so that the inlet channel is expanded in stages, which can balance the pressure of the entire pipeline system and avoid overloading of a single inclined tube sedimentation chamber 3. When the water volume is low, only a small number of inclined filter tubes 6 are working. This can concentrate the limited water pressure to increase the water flow rate, reduce the sewage retention in the idle inclined tube sedimentation chamber 3, avoid filter media caking caused by suspended solids, and dynamically adapt the treatment unit according to the actual water volume to reduce the equipment's ineffective energy consumption. The clarified wastewater in the inclined tube sedimentation tank 3 flows into the bottom of the aeration tank 4 through the upper outlet pipe 14. The floating valve assembly drives the second sealing component synchronously through the transmission structure, wrapping or spreading the second flexible pad 25, and dynamically adjusting the effective number of filter shells 10 and aeration pipes 11. The ceramic filter material in the filter shell 10 intercepts fine suspended solids, and the aeration pipe 11 releases bubbles through the air outlet 12 to oxidize and decompose organic matter. When the water volume is high, multiple sets of filter shells 10 and aeration pipes 11 run in parallel, maximizing the total treatment area. This can quickly divert a large amount of wastewater under high water pressure, effectively disperse the pressure load in the aeration tank 4, and prevent the ceramic filter material of a single set of filter shells 10 from being damaged due to overload, or the air outlet 12 of the aeration pipe 11 from being blocked due to the impact of high-pressure water flow, ensuring stable operation of filtration and aeration under high water volume conditions. When the water volume is low, a small number of filter shells 10 and aeration pipes 11 are opened to concentrate the limited water pressure and ensure the flow rate of water through the ceramic filter media. This avoids water flow stagnation and filter media blockage caused by low water volume. At the same time, a small number of aeration pipes 11 concentrate aeration to fully contact the sewage, improve the efficiency of organic matter oxidation and decomposition, and avoid energy waste caused by redundant aeration. By using sealing plate 13, the wastewater is ensured to be filtered before being discharged, thus improving the treatment effect; Regularly check the amount of sludge accumulated in the conical sludge hopper 7. When the preset amount is reached, open the drain pipe 8 valve on the outside of the sludge hopper to discharge the deposited sludge. This prevents sludge from accumulating in the sedimentation chamber and affecting the solid-liquid separation efficiency, prevents sludge from flowing back and contaminating the treated wastewater, and ensures the continuous and stable operation of the sedimentation process. The qualified wastewater after deep treatment in aeration chamber 4 is discharged from the upper outlet pipe 32 on the side of aeration chamber 4 away from inclined tube sedimentation chamber 3.
