Description

Technical Field

[0001] This invention belongs to the field of cyanobacteria pollution filtration technology, specifically a cyanobacteria pollution filtration treatment device and method based on activated carbon. Background Technology

[0002] Cyanobacterial pollution refers to the imbalance of aquatic ecosystems caused by the excessive proliferation of cyanobacteria. Cyanobacteria are photosynthetic prokaryotes that obtain nutrients through nitrogen fixation. They multiply rapidly in eutrophic waters (excessive nitrogen and phosphorus), forming algal blooms. Activated carbon mainly removes algae, toxins, and odors through adsorption in the treatment of cyanobacterial pollution.

[0003] In current processes for filtering cyanobacterial pollutants using activated carbon, as the volume of cyanobacterial wastewater continues to increase, the surface of the activated carbon gradually becomes saturated due to the excessive adsorption of cyanobacteria, leading to pore blockage and a decrease in specific surface area, which in turn significantly reduces filtration efficiency. Traditional solutions rely on manual periodic disassembly and replacement of activated carbon components, but this method has obvious limitations: on the one hand, frequent manual operations consume a lot of time and labor costs; on the other hand, repeated disassembly and assembly can easily cause mechanical fatigue of the activated carbon support structure or filtration equipment, and may even cause wear of seals or loosening of connecting parts, thereby shortening the service life of the entire filtration system. In addition, improper operation during manual replacement may lead to secondary pollution or leakage of activated carbon particles, further affecting the stability and reliability of the treatment system. Therefore, a cyanobacterial pollution filtration treatment device and method based on activated carbon is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a cyanobacteria pollution filtration and treatment device and method based on activated carbon.

The activated carbon storage assembly includes a second filter cartridge fixed inside the processing chamber. A first filter cartridge is installed inside the second filter cartridge. One end of the second filter cartridge is fixedly connected to the first filter cartridge, and the other end is open. The second filter cartridge and the first filter cartridge together form an activated carbon storage chamber. A transmission plate is movably provided at one end of the processing chamber, and the transmission plate is movably engaged with the opening at the other end of the first filter cartridge and the second filter cartridge; An arc-shaped plate is arranged in a ring array on one side of the transmission plate. The arc-shaped plate is located in the activated carbon storage chamber formed by the second filter cartridge and the first filter cartridge, so that the activated carbon storage chamber is divided into several cavities. The top of the processing chamber is equipped with a feeding pipe that communicates with the activated carbon storage chamber, and the bottom of the processing chamber is equipped with a discharge pipe that communicates with the activated carbon storage chamber.

[0006] Preferably, a drive motor is installed on the top of the unmanned vessel, and an output shaft is fitted at the output end of the drive motor; A docking frame is installed on the other side of the transmission plate, and the output shaft is connected to the docking frame through a docking component.

[0007] Preferably, the docking component includes a fixing frame fixed to the end of the processing chamber, a slip ring movably sleeved on the side of the fixing frame, a first hydraulic rod mounted on the slip ring, and a docking rod mounted on the output end of the first hydraulic rod via a connector; One end of the connecting rod is axially movably connected to the output shaft.

[0008] Preferably, the outer annular array of the docking rod is provided with docking bars, and the inner wall of the docking frame is provided with a slot; The first hydraulic rod pushes the docking rod, which disengages from the transmission rod, causing the docking strip to engage in the slot.

[0009] Preferably, the activated carbon storage assembly further includes a transmission rod disposed inside the first filter cartridge, a stabilizing frame is disposed inside the first filter cartridge, and impellers are equidistantly mounted on the outside of the transmission rod; The first hydraulic rod drives the docking rod to move in the opposite direction, and the docking rod is cross-connected to the end of the transmission rod.

[0010] Preferably, the filter assembly includes a mounting frame fixed to the outside of the processing chamber, and a winding shaft is provided on the mounting frame, the end of which is driven by a motor; The outer side of the take-up shaft is wrapped with filter cloth. The mounting frame, take-up shaft and guide frame are symmetrically installed on both sides of the processing chamber. One of the take-up shafts is wrapped with unused filter cloth, while the other take-up shaft is wrapped with used filter cloth.

[0011] Preferably, a guide shaft is installed on the outside of the second filter cartridge, and the filter cloth is guided by the guide shaft to wrap around the outside of the second filter cartridge; The mounting frame is equipped with a guide frame that supports the filter cloth.

[0012] Preferably, a drainage assembly is provided at the other end of the processing chamber. The drainage assembly includes a rubber cover disposed at the other end of the processing chamber. The rubber cover is funnel-shaped, and an elastic element is provided at the end of the rubber cover. The first and second filter cartridges are provided with support plates arranged in a ring at their ends, and the support plates are located inside the rubber cover.

[0013] Preferably, a second hydraulic rod is installed at one end of the inner wall of the first filter cartridge, and the output end of the second hydraulic rod is equipped with a ring that contacts the inner wall of the support plate.

[0014] This invention also provides a method for filtering and treating cyanobacteria pollution based on activated carbon, comprising the following steps: S1. Blue-green algae wastewater enters the interior of the treatment chamber through the side and is first filtered by the filter components.

[0015] S2. The cyanobacteria wastewater that has undergone preliminary filtration is then filtered a second time through activated carbon, and the filtered wastewater is discharged through the drainage system.

[0016] S3. When it is necessary to replace the activated carbon, the operator opens the discharge pipe and drives the output shaft, docking parts, docking frame, transmission plate and arc plate to rotate through the drive motor. As the arc plate continues to rotate, the activated carbon in the storage chamber is gradually pushed towards the discharge pipe under the combined action of centrifugal force and gravity, and discharged through the discharge pipe.

[0017] S4. After the activated carbon is emptied, new activated carbon can be injected through the injection pipe to complete the replacement.

[0018] S5. After the new activated carbon is injected, a storage structure with several chambers is formed again. At this time, the transmission plate returns to the initial position and continues to treat the blue-green algae wastewater. The unmanned vessel can move to the next area to carry out blue-green algae pollution filtration treatment.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: This invention achieves automatic activated carbon replacement by driving an arc-shaped plate to rotate via a drive motor. When activated carbon needs to be replaced, the drive motor drives the output shaft, docking parts, docking frame, transmission plate, and arc-shaped plate to rotate. The rotation of the arc-shaped plate gradually pushes the activated carbon in the storage chamber toward the discharge pipe for discharge. Then, new activated carbon is injected through the injection pipe. This mechanical and automated replacement method eliminates the need for manual entry into the processing chamber for disassembly and installation, significantly shortening the replacement time and reducing labor costs.

[0020] This invention achieves automatic winding and replacement of the filter cloth via a motor-driven winding shaft, eliminating the need for manual disassembly of the treatment chamber or interruption of the entire filtration system to update the filter layer. Compared to traditional technologies that require periodic manual disassembly and replacement of the entire filter assembly, this application enables continuous automatic replacement of the filter layer, significantly reducing the frequency and time costs of manual maintenance. It also avoids problems such as wear on seals and loosening of connecting parts caused by frequent disassembly and assembly, extending the service life of the entire filtration equipment and improving the continuity and stability of cyanobacteria pollution treatment.

[0021] This invention drives an output shaft to rotate via a drive motor. The output shaft transmits power to the inside of the first filter cartridge through a connecting rod, a transmission rod, and an impeller. The impeller rotates inside the first filter cartridge, and under the action of centrifugal force, the cyanobacteria wastewater entering the first filter cartridge rotates and flows, accelerating the contact and filtration reaction between the wastewater and activated carbon, and significantly improving the treatment efficiency of cyanobacteria wastewater.

Detailed Implementation

[0024] 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, and 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.

[0025] like Figures 1 to 10 As shown, the present invention provides a cyanobacteria pollution filtration and treatment device based on activated carbon, including an unmanned vessel 1, and further comprising: Processing compartment 3 is installed inside the unmanned vessel 1 via support frame 2; Activated carbon storage component 4 is installed inside the treatment chamber 3 and is used to filter blue-green algae wastewater; The filter assembly 5 is installed on the treatment chamber 3 and is covered outside the activated carbon storage assembly 4 for preliminary filtration of blue-green algae wastewater. The activated carbon storage component 4 includes a second filter cartridge 46 fixed inside the processing chamber 3. A first filter cartridge 45 is installed inside the second filter cartridge 46. One end of the second filter cartridge 46 is fixedly connected to the first filter cartridge 45, and the other end is open. The second filter cartridge 46 and the first filter cartridge 45 form an activated carbon storage chamber. A transmission plate 48 is movably provided at one end of the processing chamber 3, and the transmission plate 48 is movably engaged with the opening at the other end of the first filter cartridge 45 and the second filter cartridge 46. An arc-shaped plate 49 is arranged in a ring array on one side of the transmission plate 48. The arc-shaped plate 49 is located in the activated carbon storage chamber formed by the second filter cartridge 46 and the first filter cartridge 45, so that the activated carbon storage chamber is divided into several cavities. The top of the processing chamber 3 is equipped with a feeding pipe 44 that communicates with the activated carbon storage chamber, and the bottom of the processing chamber 3 is equipped with a discharge pipe 47 that communicates with the activated carbon storage chamber. The unmanned vessel 1 is equipped with a drive motor on its top, and the output end of the drive motor is fitted with an output shaft 41; A docking frame 43 is installed on the other side of the transmission plate 48, and the output shaft 41 is connected to the docking frame 43 through the docking piece 42.

[0026] Blue-green algae wastewater enters the treatment chamber 3 through its side. It first undergoes preliminary filtration through filter assembly 5, removing larger algae filaments and suspended solids, thus reducing the adsorption burden on the activated carbon. The pre-filtered wastewater then undergoes secondary filtration through activated carbon. The porous structure of the activated carbon adsorbs organic pollutants and algal metabolites from the wastewater. The filtered wastewater is then discharged through drainage assembly 6. This preliminary filtration step, using filter assembly 5 as a pretreatment, effectively reduces the direct adsorption burden on the activated carbon, preventing large algae particles from directly entering the activated carbon storage chamber and causing rapid clogging of the activated carbon micropores. This extends the effective lifespan of the activated carbon and maintains its specific surface area and adsorption efficiency.

[0027] When activated carbon needs to be replaced, the operator opens the discharge pipe 47 and drives the output shaft 41, docking piece 42, docking frame 43, transmission plate 48, and arc plate 49 to rotate via the drive motor. As the arc plate 49 continues to rotate, the activated carbon in the storage chamber is gradually pushed towards the discharge pipe 47 under the combined action of centrifugal force and gravity, and discharged through the discharge pipe 47. After the activated carbon is emptied, new activated carbon is injected through the injection pipe 44 to complete the replacement.

[0028] This step achieves automatic discharge and replenishment of activated carbon through a mechanical method that drives the transmission plate and arc plate to rotate via a drive motor. No manual entry into the treatment chamber for disassembly and installation is required, significantly reducing the time and labor costs associated with replacing activated carbon. Furthermore, since the entire replacement process is completed within the sealed filter cartridge structure, it avoids issues such as wear on seals or loosening of connections caused by improper operation during manual disassembly. This reduces the impact of mechanical fatigue on equipment lifespan and extends the overall service life of the filtration system.

[0029] Furthermore, the rotation of the arc-shaped plate 49 evenly loosens the activated carbon and pushes it towards the discharge pipe 47, ensuring that the activated carbon can be completely discharged and avoiding the problem of particle leakage of residual activated carbon during the replacement process. The entire replacement process is completed within the sealed space of the treatment chamber 3, effectively preventing secondary pollution caused by activated carbon particle leakage during the replacement process, and ensuring the stability and reliability of the blue-green algae pollution filtration and treatment system.

[0030] After the new activated carbon is injected, a storage structure with several chambers is reformed. At this time, the transmission plate 48 returns to its initial position and continues to treat the cyanobacterial wastewater. Through the autonomous navigation and positioning function of the unmanned vessel 1, the treatment equipment can perform mobile filtration treatment of cyanobacterial pollution in different areas, realizing automated and intelligent operation of cyanobacterial pollution control.

[0031] like Figure 3 - Figure 7 As shown, the docking component 42 includes a fixing frame 421 fixed to the end of the processing chamber 3. A slip ring 422 is movably sleeved on the side of the fixing frame 421. A first hydraulic rod 423 is installed on the slip ring 422. The output end of the first hydraulic rod 423 is connected to a docking rod 425 through a connector 424. One end of the docking rod 425 is axially movably connected to the output shaft 41; The outer annular array of the docking rod 425 is provided with docking bars 426, and the inner wall of the docking frame 43 is provided with a slot 40; The first hydraulic rod 423 pushes the docking rod 425, disengaging the docking rod 425 from the transmission rod 411, causing the docking strip 426 to engage in the slot 40. The activated carbon storage assembly 4 also includes a transmission rod 411 disposed inside the first filter cartridge 45, a stabilizer 413 disposed inside the first filter cartridge 45, and impellers 412 equidistantly mounted on the outside of the transmission rod 411. The first hydraulic rod 423 drives the docking rod 425 to move in the opposite direction, and the docking rod 425 is cross-connected to the end of the transmission rod 411.

[0032] When activated carbon replacement or wastewater treatment is required, the first hydraulic rod 423 slides on the fixed frame 421 via the slip ring 422, pushing the docking rod 425 forward. The docking strips 426, arranged in a ring array on the outside of the docking rod 425, engage with the slots 40 on the inner wall of the docking frame 43 under the push of the first hydraulic rod 423. At this time, the docking rod 425 disengages from the transmission rod 411 and achieves a stable connection with the docking frame 43 through engagement, preparing for subsequent transmission.

[0033] The first hydraulic rod 423 drives the docking rod 425 to move in the opposite direction, so that the docking rod 425 is cross-connected with the end of the transmission rod 411 located inside the first filter cartridge 45. The axial movable connection structure realizes the reliable linkage between the docking rod 425 and the transmission rod 411. At the same time, the hydraulic drive of the first hydraulic rod 423 controls the extension and retraction of the docking rod 425, realizing the flexible switching between the docking mechanism and different components.

[0034] After the docking mechanism completes the connection, the drive motor drives the output shaft 41 to rotate. The output shaft 41 transmits power to the inside of the first filter cartridge 45 through the docking rod 425, the transmission rod 411, and the impeller 412 in sequence. The impeller 412 rotates inside the first filter cartridge 45, and under the action of centrifugal force, it causes the cyanobacteria wastewater entering the first filter cartridge 45 to rotate and flow, accelerating the contact and filtration reaction between the wastewater and the activated carbon, and significantly improving the treatment efficiency of the cyanobacteria wastewater.

[0035] like Figure 9 and Figure 10 As shown, the filter assembly 5 includes a mounting frame 53 fixed to the outside of the processing chamber 3, and a winding shaft 54 ​​is provided on the mounting frame 53. The end of the winding shaft 54 ​​is driven by a motor. The outer side of the take-up shaft 54 ​​is wrapped with filter cloth 52. The mounting frame 53, the take-up shaft 54 ​​and the guide frame 55 are symmetrically installed on both sides of the processing chamber 3. One of the take-up shafts 54 is wrapped with unused filter cloth 52, while the other take-up shaft 54 ​​is wrapped with used filter cloth 52. A guide shaft 51 is installed on the outside of the second filter cartridge 46, and the filter cloth 52 is guided by the guide shaft 51 to wrap around the outside of the second filter cartridge 46. The mounting bracket 53 is equipped with a guide bracket 55 that supports the filter cloth 52.

[0036] Blue-green algae wastewater enters treatment chamber 3 and undergoes preliminary filtration through filter cloth 52. Guided by guide shaft 51, filter cloth 52 wraps around the outside of the second filter cartridge 46, forming a filtration layer. Larger blue-green algae particles and suspended solids adhere to the surface of filter cloth 52. The wastewater passes through filter cloth 52 into the activated carbon storage chamber between the second filter cartridge 46 and the first filter cartridge 45, where it undergoes deep filtration by the activated carbon. This step, by using filter cloth 52 as a pre-filtration layer, effectively intercepts larger blue-green algae filaments and suspended solids, preventing large particles from directly entering the activated carbon storage chamber and causing blockage, thus protecting the adsorption performance of the activated carbon and extending its effective service life.

[0037] As the amount of blue-green algae adhering to the surface of the filter cloth 52 gradually increases, the filtration resistance increases and the filtration efficiency decreases. At this time, one of the winding shafts 54 is driven by a motor to rotate, winding the filter cloth 52. During the winding process, the used filter cloth 52 is wound and wound onto the winding shaft 54, while the unused filter cloth 52 wound on the other winding shaft 54 ​​gradually loosens and is released. Guided by the guide frame 55, it enters the processing chamber 3 and wraps around the outside of the second filter cartridge 46, forming a new filtration layer.

[0038] After the new filter cloth 52 is in place, it continues to perform preliminary filtration of the cyanobacteria-laden wastewater. The used filter cloth 52 is continuously wound up and centrally processed by the winding shaft 54, and can be cleaned or replaced periodically.

[0039] like Figure 3As shown, a drainage assembly 6 is provided at the other end of the processing chamber 3. The drainage assembly 6 includes a rubber cover 64 provided at the other end of the processing chamber 3. The rubber cover 64 is funnel-shaped and an elastic member 65 is provided at the end of the rubber cover 64. The ends of the first filter cartridge 45 and the second filter cartridge 46 are provided with a ring array of support plates 63, which are located inside the rubber cover 64. A second hydraulic rod 61 is installed at one end of the inner wall of the first filter cartridge 45, and an annular part 62 that contacts the inner wall of the support plate 63 is assembled at the output end of the second hydraulic rod 61.

[0040] The second hydraulic rod 61 pushes the ring 62 forward, which in turn pushes the support plate 63 outward. The support plate 63 further expands the rubber cover 64 and the elastic member 65, thereby opening the drainage channel. By controlling the degree of advancement of the second hydraulic rod 61, the degree of expansion of the support plate 63 pushed by the ring 62 can be precisely adjusted, thereby controlling the flow rate of the blue-green algae wastewater discharge.

[0041] This invention also provides a method for filtering and treating cyanobacteria pollution based on activated carbon, comprising the following steps: S1. Blue-green algae wastewater enters the interior of treatment chamber 3 through the side of treatment chamber 3 and is first filtered by filter assembly 5.

[0042] S2. The cyanobacteria wastewater that has undergone preliminary filtration is then filtered a second time through activated carbon, and the filtered wastewater is discharged through drainage component 6.

[0043] S3. When it is necessary to replace the activated carbon, the operator opens the discharge pipe 47 and drives the output shaft 41, docking part 42, docking frame 43, transmission plate 48 and arc plate 49 to rotate through the drive motor. As the arc plate 49 continues to rotate, the activated carbon in the storage chamber is gradually pushed towards the discharge pipe 47 under the combined action of centrifugal force and gravity, and discharged through the discharge pipe 47.

[0044] S4. After the activated carbon is emptied, new activated carbon can be injected through the injection pipe 44 to complete the replacement.

[0045] S5. After the new activated carbon is injected, a storage structure with several chambers is formed again. At this time, the transmission plate 48 returns to its initial position and continues to treat the blue-green wastewater. The unmanned vessel 1 can move to the next area to carry out blue-green pollution filtration treatment.

S4. After the activated carbon is emptied, new activated carbon can be injected through the injection pipe (44) to complete the replacement. S5. After the new activated carbon is injected, a storage structure with several chambers is formed again. At this time, the transmission plate (48) returns to the initial position and continues to treat the blue-green wastewater. The unmanned vessel (1) can move to the next area to carry out blue-green pollution filtration treatment.
