Description

Technical Field

[0001] This invention relates to the field of water suspended solids elution technology, and in particular to an integrated ecological purification system for water suspended solids elution. Background Technology

[0002] In aquatic ecosystems, sediment and suspended solids are key factors affecting water quality. Sediment serves as a significant accumulation site for pollutants in water bodies, containing large amounts of nitrogen, phosphorus, heavy metals, and organic pollutants. These pollutants are continuously released into the water body through material exchange between the sediment and the water, causing secondary pollution and contributing significantly to eutrophication and water quality deterioration. Suspended solids, on the other hand, reduce water transparency, impair photosynthesis in aquatic plants, and may also adsorb pollutants, migrating and transforming within the water, further harming the aquatic ecosystem. Therefore, effective treatment of sediment and suspended solids is crucial for improving water quality and restoring aquatic ecosystems.

[0003] In existing suspended solids washing devices, traditional sediment agitation equipment often employs a single-shaft or simple twin-shaft agitation structure. In practical applications, this structure has a limited agitation range, failing to adequately cover all areas of the water bottom. In large lake remediation, single-shaft agitators only affect the sediment near the agitator shaft, leaving sediment further away without effective agitation, hindering pollutant release and impacting subsequent treatment. Because the agitator shaft's rotation speed, angle, and depth are fixed, they cannot be flexibly adjusted according to the different characteristics of the sediment. For deep sediment, the agitation force may be insufficient, failing to adequately agitate it; while for shallow sediment, over-aggregation may increase turbidity, affecting the habitat of aquatic organisms. Traditional jet agitation devices typically have only one jet outlet, resulting in a single-direction water flow and a narrow agitation range. In river sediment remediation, such single-jet-outlet devices struggle to reach all corners of the river when facing complex river topography. In bends, narrow sections, and areas near the banks of rivers, water flow is easily obstructed, creating stagnant zones where pollutants in the sediment cannot be effectively treated. Over time, these pollutants accumulate and continuously pollute the water.

[0004] During sediment collection, the sediment often contains various impurities, such as twigs, stones, weeds, and particles of different sizes. Existing collection devices struggle to effectively separate sediment from impurities during operation, resulting in a significant amount of impurities being sucked in along with the sediment. This contamination increases the difficulty and cost of subsequent sediment treatment. In later treatment stages, such as dewatering and solidification, impurities may damage equipment, affecting treatment efficiency and potentially causing the treated sediment to fail to meet emission standards, necessitating secondary treatment. Summary of the Invention

[0005] To address the problems mentioned in the background section, this invention provides an integrated ecological purification system for eluting suspended solids in water.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An integrated ecological purification system for eluting suspended solids in water includes a suspended solids catcher, a treatment agent mixer, a flocculation sedimentation tank, and a plate and frame filter press. The suspended solids catcher includes a lifting support mounted on a fishing boat. The lifting support is equipped with a fixed shaft and a rotating shaft. Multiple mounting brackets are fixed on the rotating shaft, and a vertical shaft is rotatably mounted on the mounting bracket. A disturbance screw is provided at the bottom end of the vertical shaft. A sector-shaped frame is fixed on the fixed shaft. The rotating shaft passes through the center of the sector-shaped frame. A first helical gear and a second helical gear are rotatably mounted on the top of the vertical shaft through one-way bearings. The sector-shaped frame has an arc-shaped distribution of first and second helical teeth on the side near the vertical shaft. The first helical teeth mesh with the first helical gear, and the second helical teeth mesh with the second helical gear.

[0008] Preferably, the rotating shaft is driven to reciprocate by a rotary motor, and multiple vertically arranged stirring branches are fixed on the disturbance screw.

[0009] Preferably, a worm gear is provided on the outside of the vertical shaft above the disturbing spiral ribbon, a slow stirring rod is rotatably mounted on the mounting bracket, a worm wheel is fixed on the slow stirring rod, and the worm wheel and the worm gear mesh with each other.

[0010] Preferably, the vertical shaft is hollow inside, and the top of the vertical shaft is provided with a jet pipe interface. The jet pipe interface is connected to the jet pump through a connector and a hose. The jet pump draws the clean water treated by the flocculation sedimentation tank into the vertical shaft.

[0011] Preferably, the bottom end of the vertical axis is provided with a spray head, and there are multiple spray heads, which are distributed in a ring array at the bottom end of the vertical axis.

[0012] Preferably, the slow-speed stirring rod has multiple stirring blades fixed to its exterior, and multiple vertical shafts are equidistantly distributed along the extension direction of the rotation axis.

[0013] Preferably, the fixed shaft is hollow inside, and one end of the fixed shaft is provided with a suction pipe interface, which is connected to a suction pump, and the suction pump draws water into the flocculation sedimentation tank.

[0014] Preferably, the fixed shaft is provided with multiple suction inlets, and a filter screen is installed on the outside of the suction inlets, and a solid collection container is fixed on the mounting frame.

[0015] Preferably, a strip scraper is fixed above the solid collection container, the side of the filter screen close to the strip scraper is curved, and the strip scraper is in contact with the surface of the filter screen.

[0016] Preferably, the solid collection container has a discharge port on one side, and the discharge port is far away from the disturbing screw. A discharge screw is rotatably installed inside the solid collection container. One end of the discharge screw extends to the outside of the solid collection container through the discharge port. A first pulley is fixed on a slow stirring rod, and a second pulley is fixed on the output shaft of the discharge screw. A belt is sleeved between the outside of the first pulley and the second pulley.

[0017] Compared with the prior art, the beneficial effects of the present invention are:

[0018] 1. High-efficiency sediment disturbance: The unique structural design of the suspended solids catcher uses the reciprocating rotation of the rotating shaft to drive the mounting frame and vertical shaft to swing. Utilizing a one-way bearing and the arc-shaped helical teeth on the sector frame, the vertical shaft can rotate in both directions at different speeds and with different numbers of revolutions. On one hand, this enhances the disturbance effect of the disturbance screw and mixing branches on the river water, expands the mixing coverage area, and changes the mixing angle, thus improving the efficiency of sediment disturbance. On the other hand, it drives the disturbance screw to rotate more revolutions in a specific direction, pushing the mud-water mixture upwards for easier subsequent suction, effectively solving the problems of limited mixing range and inflexible adjustment of mixing intensity in traditional mixing equipment.

[0019] 2. Precise Layered Mixing: When the vertical shaft rotates, the worm gear drives the slow-speed mixing rod to slowly rotate in both directions, resulting in gentle mixing of shallow water and avoiding over-mixing. Different mixing forces are used for water depths, preventing damage to shallow aquatic habitats and plants, while also achieving rational power distribution, reducing energy consumption, and improving energy efficiency, thus overcoming the shortcomings of traditional equipment in layered mixing.

[0020] 3. Powerful auxiliary disturbance: The vertical shaft is hollow inside and connected to a jet pump, with multiple jet heads arranged in a ring array at the bottom. The jet heads eject high-pressure water to assist in disturbing the bottom sediment, and the reciprocating swing of the vertical shaft changes the position and direction of the jet, expanding the disturbance range and improving the disturbance effect. This overcomes the shortcomings of traditional jet disturbance devices, such as the single direction of water flow impact and the narrow disturbance range.

[0021] 4. Effective Impurity Treatment: A filter screen is installed outside the suction inlet on the fixed shaft to prevent large particles from entering. The solid collection container on the mounting frame, along with a strip scraper, can promptly clean impurities from the filter screen surface to prevent clogging. Simultaneously, the solid collection container automatically discharges material via a discharge screw, with the discharge port located away from disturbing screw conveyors to prevent collected impurities from being re-entered into the water. This solves the problems of existing collection devices struggling to separate bottom sludge and impurities, and impurities easily damaging subsequent treatment equipment, thus reducing treatment difficulty and cost.

[0022] 5. Overall Purification Advantages: This integrated system works in concert with suspended solids catchers, treatment agent mixers, flocculation sedimentation tanks, and plate and frame filter presses to form a complete and efficient ecological purification process for suspended solids elution in water bodies, from bottom sediment disturbance and impurity filtration and collection to mud and water purification treatment. It significantly improves water quality, helps restore aquatic ecosystems, and has high social value and broad application prospects. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0035] Example 1

[0036] Reference Figure 1-9 An integrated ecological purification system for eluting suspended solids in water includes a suspended solids catcher 1, a treatment agent mixer 2, a flocculation sedimentation tank 3, and a plate and frame filter press 4. The suspended solids catcher 1 includes a lifting support 101, which is mounted on a fishing boat. The lifting support 101 is equipped with a fixed shaft 5 and a rotating shaft 6. Multiple mounting brackets 602 are fixed on the rotating shaft 6. A vertical shaft 603 is rotatably mounted on the mounting bracket 602. The bottom end of the vertical shaft 603 is equipped with a disturbance screw 603. 2. A sector-shaped frame 502 is fixed on the fixed shaft 5. A rotating shaft 6 passes through the center of the sector-shaped frame 502. A first helical gear 6034 and a second helical gear 6035 are rotatably mounted on the top of the vertical shaft 603 through one-way bearings. The sector-shaped frame 502 is provided with an arc-shaped first helical tooth 5021 and a second helical tooth 5022 on the side of the sector-shaped frame 502 close to the vertical shaft 603. The first helical tooth 5021 meshes with the first helical gear 6034, and the second helical tooth 5022 meshes with the second helical gear 6035.

[0037] A suspended solids catcher 1 is installed on a fishing boat and extends to the bottom of the water. The catcher 1 disturbs the bottom sediment, and the mud-water mixture is then filtered and pumped into a flocculation sedimentation tank 3. The treatment agent mixer 2 contains a dehydrating agent and a flocculant. The flocculant is polyaluminum chloride, which is transported to the flocculation sedimentation tank 3. The dehydrating agent is polyacrylamide, which is transported to a plate and frame filter press 4. By adding polyaluminum chloride, the suspended particles agglomerate into larger flocs, accelerating the sedimentation process and improving sedimentation efficiency. The treated water is discharged back into the river, and the sediment is filtered by the plate and frame filter press 4.

[0038] Among them, the rotating shaft 6 is driven to reciprocate by the rotary motor 601, and multiple vertically arranged stirring branches 6033 are fixed on the disturbance screw ribbon 6032;

[0039] The reciprocating rotation of the rotating shaft 6 can drive the mounting bracket 602 and the rotating shaft 6 on the mounting bracket 602 to swing back and forth as a whole. When the rotating shaft 6 swings back and forth, the first helical gear 6034 moves along the first helical tooth 5021 and the second helical gear 6035 moves along the second helical tooth 5022. Due to the presence of the one-way bearing and the opposite transmission directions of the two one-way bearings, when the rotating shaft 6 swings back and forth as a whole, at the same time, only one of the first helical gear 6034 and the second helical gear 6035 will drive the vertical shaft 603 to rotate. And because the diameters of the first helical tooth 5021 and the second helical tooth 5022 are different, the rotation speed and number of revolutions of the rotating shaft 6 in both directions are different when the rotating shaft 6 swings back and forth.

[0040] On the one hand, it can drive the rotating shaft 6 to rotate in both directions, thereby improving the disturbance effect of the disturbance ribbon 6032 and the stirring branch 6033 on the river water, improving the efficiency of bottom sediment disturbance, and the back-and-forth swing of the rotating shaft 6 can increase the stirring coverage of the rotating shaft 6, and can continuously change the stirring angle to improve the stirring effect.

[0041] On the other hand, due to the different rotation speeds and number of rotations in both directions, the disturbance screw 6032 can rotate more times in one direction. The direction with more rotations is the opposite direction that pushes the water to flow upward, thus enabling the mud-water mixture to move upward as a whole, which facilitates suction.

[0042] Example 2

[0043] Reference Figure 1-9The difference between this embodiment and embodiment 1 is that a worm gear 6031 is provided on the outside of the vertical shaft 603 above the disturbance screw ribbon 6032, a slow stirring rod 604 is rotatably mounted on the mounting bracket 602, a plurality of stirring blades 6041 are fixed on the outside of the slow stirring rod 604, a plurality of vertical shafts 603 are equidistantly distributed along the extension direction of the rotating shaft 6, a worm wheel 6042 is fixed on the slow stirring rod 604, and the worm wheel 6042 meshes with the worm gear 6031.

[0044] When the vertical shaft 603 rotates, it drives the slow-speed stirring rod 604 to slowly rotate in both directions through the meshing of the worm gear 6042 and the worm 6031. This results in less stirring force in shallow water, allowing for different stirring forces to be applied according to the needs of water at different depths, thus avoiding energy waste caused by excessive stirring of shallow water. This rational allocation of power allows the system to meet purification requirements while reducing energy consumption and improving energy efficiency. Furthermore, shallow water is a habitat and breeding ground for many aquatic organisms, such as fish eggs and fry, and is also a major distribution area for aquatic plants. The lower stirring force avoids direct harm to aquatic organisms, reduces physical damage to aquatic plants, maintains their normal growth, and protects the habitat and integrity of the ecosystem.

[0045] The vertical shaft 603 is hollow inside, and its top end is equipped with a jet pipe interface. The jet pipe interface is connected to a jet pump via a connector and a hose. The jet pump draws the clean water treated by the flocculation sedimentation tank 3 into the vertical shaft 603. The bottom end of the vertical shaft 603 is equipped with a jet head 6036, and there are multiple jet heads 6036 arranged in a ring array at the bottom end of the vertical shaft 603. High-pressure water jets are ejected through the jet heads 6036 to assist in disturbing the bottom sediment. Due to the reciprocating oscillation of the vertical shaft 603, the position and jet direction of the jet heads 6036 can be continuously changed, resulting in a larger disturbance range and a better disturbance effect.

[0046] Example 3

[0047] Reference Figure 1-9The difference between this embodiment and embodiment 1 is that the fixed shaft 5 is hollow inside, and one end of the fixed shaft 5 is provided with a suction pipe interface. The suction pipe interface is connected to a suction pump, which draws water into the flocculation sedimentation tank 3. The fixed shaft 5 is provided with multiple suction inlets, and a filter screen 501 is installed on the outside of the suction inlets. A solid collection container 7 is fixed on the mounting frame 602. The agitation screw ribbon 6032 and the stirring branch 6033 strongly agitate the bottom sediment and other substances at the bottom of the water, so that the pollutants originally deposited at the bottom mix with the water to form a mud-water mixture. These mixtures gradually float to the surface under the stirring action. The mud-water mixture that floats to the surface is immediately captured by the suction inlet on the fixed shaft 5. Under the negative pressure generated by the suction pump, it quickly flows into the interior of the fixed shaft 5. When passing through the filter screen 501, larger particles of impurities, such as tree branch fragments, sand particles, and large pieces of organic debris, are blocked and retained on the surface of the filter screen 501. The relatively clear mud-water that has undergone preliminary filtration continues to pass through the fixed shaft 5 and is transported to the flocculation sedimentation tank 3 for further purification treatment.

[0048] Among them, a strip scraper 703 is fixed above the solid collection container 7, and the side of the filter screen 501 near the strip scraper 703 is arc-shaped, and the strip scraper 703 is in contact with the surface of the filter screen 501.

[0049] The solid collection container 7 is used to receive the filtered solid impurities. Since the solid collection container 7 is fixed to the mounting bracket 602, it will swing back and forth with the vertical shaft 603. During the swing of the vertical shaft 603, the strip scraper 703 will clean and scrape the filter material along the outer surface of the strip scraper 703, which can prevent the filter screen 501 from being clogged due to too much filter material adhering to it, thus reducing the filtration efficiency.

[0050] The solid collection container 7 has a discharge port 702 on one side, and the discharge port 702 is far away from the disturbance screw 6032. A discharge screw 701 is rotatably installed inside the solid collection container 7. One end of the discharge screw 701 extends to the outside of the solid collection container 7 through the discharge port 702. A first pulley 6043 is fixed on a slow stirring rod 604, and a second pulley 704 is fixed on the output shaft of the discharge screw 701. A belt is sleeved between the outside of the first pulley 6043 and the second pulley 704.

[0051] Driven by the belt, the rotation of the slow-speed stirring rod 604 drives the discharge screw 701 to rotate. When the discharge screw 701 reciprocates, it rotates more times in one direction, and this direction pushes the solid filter material towards the discharge port 702. This gradually discharges the solid filter material from the discharge port 702. Since the discharge port 702 is far away from the agitation screw belt 6032, the possibility of the collected solid filter material being stirred back into the water and sucked back to the filter screen 501 during subsequent processing due to the continuous agitation of the agitation screw belt 6032 is eliminated. This greatly improves the stability and efficiency of the entire filtration and collection process.
