Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a comprehensive wastewater treatment device for indigo production. Background Technology

[0002] Wastewater generated during indigo production contains a large amount of pollutants and requires multiple treatment processes, including pretreatment, air flotation filtration, membrane filtration, and MVR evaporator concentration, desalination, and adsorption. In the later stages of treatment, magnetic powder is added to the wastewater. The magnetic powder binds with the pollutants to form high-density flocs, which rapidly settle in a sedimentation tank under the influence of gravity and the magnetic field. The settled flocs are typically scraped into the central sludge outlet at the bottom of the sedimentation tank by a sludge scraper, then pumped out and undergo solid-liquid separation to ultimately ensure the water quality meets discharge standards.

[0003] However, existing technologies have significant drawbacks: the flocs at the bottom of the sedimentation tank have a flocculent structure. During the operation of the sludge scraper, some flocs continuously adhere to the scraper surface. As the equipment continues to operate, the accumulated flocs increase the scraper mass and significantly reduce the rotation speed, severely weakening the scraping efficiency of the flocs at the bottom of the sedimentation tank. At the same time, the position of the magnetic field fixedly installed at the bottom of the equipment cannot be adjusted, affecting the uniform and sufficient formation of flocs in the wastewater and reducing the treatment effect. In addition, when the supernatant needs to be discharged for recycling after the flocs have settled, the existing method directly extracts the supernatant without effective isolation measures, which easily disturbs the floc layer, causing flocs to mix into the supernatant, resulting in pollution of the recycled water and affecting the safety of subsequent use or discharge. Summary of the Invention

[0004] The purpose of this application is to provide a comprehensive wastewater treatment device for the indigo production process, which solves the problem in the existing technology that when the supernatant needs to be discharged for recycling after the flocculation sedimentation, the existing method directly extracts the supernatant and lacks effective isolation measures.

[0005] The objective of this invention can be achieved through the following technical solutions:

[0006] A comprehensive wastewater treatment system for indigo production includes:

[0007] The treatment tank, which serves as the main installation body for the wastewater treatment equipment, has a drain pipe at its bottom and a feed pipe at its top.

[0008] The magnetic mechanism, located inside the treatment chamber, uses magnetic powder and magnetic field to cause pollutants to form high-density flocs, thereby purifying the wastewater.

[0009] The cleaning mechanism, located at the bottom inside the treatment chamber, is used to scrape the settled flocs into the drain pipe at the bottom of the treatment chamber for discharge.

[0010] The partition mechanism is located on the upper inner side of the treatment tank and is used to separate the wastewater into layers after sedimentation to prevent the supernatant from mixing with the flocculent during the discharge process.

[0011] The drive reducer is fixedly installed on the upper part of the treatment box, and its output end is fixedly connected to the drive spindle. The drive spindle extends into the inside of the treatment box and is used to drive the partition mechanism to move up and down, thereby adjusting the position of the magnetic field and making the wastewater flocs form evenly and fully. The bottom of the drive spindle is fixedly connected to the cleaning mechanism and is used to drive the cleaning mechanism to rotate, thereby cleaning and discharging the settled flocs.

[0012] Preferably, the magnetic mechanism includes a main shaft sleeve and an outer ring. The inner circumference of the main shaft sleeve is provided with an internal thread, and the outer circumference of the drive main shaft located inside the processing box is provided with an external thread that mates with the internal thread. The main shaft sleeve and the outer ring are connected by several magnet blocks. A collar slider with a rectangular structure is fixedly provided on the outer circumference of the outer ring. The side wall of the processing box is provided with a rectangular side cavity that slides with the collar slider. The collar slider slides vertically within the rectangular side cavity.

[0013] Preferably, the partition mechanism includes a housing collar and a main shaft collar. The housing collar slides against the inner wall of the processing housing, and the main shaft collar is connected to the outer periphery of the drive main shaft. A plurality of rotating partitions are rotatably arranged between the housing collar and the main shaft collar. One end of the rotating partition is rotatably mounted on the main shaft collar via a partition shaft, and the other end of the rotating partition is rotatably mounted on the housing collar via a partition shaft. The processing housing is provided with a partition drive for driving the rotating partitions to rotate.

[0014] Preferably, the partition drive includes a partition cylinder fixedly mounted on the outer wall of the treatment tank and a gear shaft fixedly connected to the partition shaft. The output end of the partition cylinder is fixedly connected to a cylinder connecting plate, and a partition slide plate is fixedly mounted at the lower end of the cylinder connecting plate. The partition slide plate slides through and extends into the interior of the treatment tank. A slide plate rack is provided on the side end of the partition slide plate located inside the treatment tank. A drive gear that meshes with the slide plate rack is fixedly mounted on the gear shaft. When it is necessary to drive the rotating partition to rotate, the ring rack is driven to move up and down through the tank collar. The gear rack meshing transmission drives the gear shaft and the partition shaft to rotate, thereby rotating the rotating partition. When it is necessary to treat wastewater, the interior of the treatment tank is vertically connected when the rotating partition is in a vertical state. When flocculants are generated and settled, the supernatant needs to be discharged. At this time, it is necessary to separate the supernatant and the turbid liquid. The rotating partition rotates to a horizontal state to form a partition.

[0015] Preferably, the outer peripheral wall of the housing collar is rotatably provided with an annular rack, and a partition gear that meshes with the annular rack is fixedly installed at one end of the partition shaft near the annular rack. The gear shaft is fixedly connected to one of the partition shafts. When the gear shaft drives one of the partition shafts to rotate, the partition gear on the partition shaft drives the annular rack to rotate. The annular rack drives other sets of partition shafts and rotating partitions to rotate synchronously, thereby achieving synchronous driving of several rotating partitions.

[0016] Preferably, the processing box is provided with a lifting mechanism for driving the partition mechanism to move up and down. A guide slide is fixedly provided on the outer periphery of the box collar and slides with the rectangular side cavity. The lifting mechanism includes a lifting motor fixedly installed on the upper end of the processing box. A lifting screw is fixedly connected to the output end of the lifting motor. A screw slider is threadedly connected to the outer periphery of the lifting screw that extends into the rectangular side cavity. The screw slider is fixedly connected to the guide slide.

[0017] Preferably, the cleaning mechanism includes a cleaning seat, a connecting bracket fixedly mounted on the upper end of the cleaning seat, and a shaft connector connected to the drive spindle on the connecting bracket; a plurality of scraper shafts are rotatably mounted on the cleaning seat, and a cleaning scraper for scraping off sediment is fixedly connected to the lower end of the scraper shaft; a decontamination mechanism for cleaning the surface of the cleaning scraper is installed on the cleaning seat, and the decontamination mechanism is drivenly connected to the shaft connector through a linkage mechanism.

[0018] Preferably, the shaft connector includes a sleeve shaft fixedly mounted on a connecting bracket, a main shaft connecting plate fixedly connected to the drive main shaft at the upper end of the sleeve shaft, both the sleeve shaft and the main shaft connecting plate being through structures, a track wheel fixedly mounted on the upper part of the scraper shaft, and multiple sets of track wheels being connected by a transmission track; the shaft center of the drive main shaft is provided with a shaft through hole, the scraper drive shaft passes through the shaft through hole and is fixedly connected to the cleaning scraper, and the drive reducer is multi-drive end, driving the scraper drive shaft and the drive main shaft to rotate respectively;

[0019] The drive reducer drives the scraper drive shaft to rotate, which in turn drives one set of cleaning scrapers to rotate. The drive belt and track wheels drive multiple sets of cleaning scrapers to rotate synchronously. By rotating the cleaning scrapers, the scraping direction and angle of the scrapers can be adjusted, ensuring that the sediment is accurately scraped into the sewage pipe and that the bottom of the treatment tank is completely scraped.

[0020] Preferably, the cleaning mechanism includes a cleaning scraper that is slidably sleeved on the outer periphery of the cleaning scraper and a linkage slide plate that is slidably installed on the cleaning seat. The lower part of the linkage slide plate is provided with several rotating grooves that match the cleaning scraper. The rotating grooves are coaxially arranged with the rotation axis of the scraper shaft. A connecting pin is fixedly installed on the cleaning scraper. A connecting pin is slidably connected on the rotating groove. A pin rod connecting plate is rotatably connected between the two sets of connecting pins. The setting of the rotating groove ensures that the cleaning scraper can maintain a normal connection between the cleaning scraper and the rotating groove when it rotates.

[0021] Preferably, the linkage mechanism includes a linkage seat plate fixedly mounted on the connecting bracket, a linkage shaft rotatably passing through the linkage seat plate, a helical gear two fixedly mounted on one end of the linkage shaft, a helical gear one fixedly mounted on the sleeve shaft and meshing with the helical gear two, a linkage turntable fixedly mounted on the other end of the linkage shaft, a coil pin fixedly connected near the edge of the linkage turntable, a linkage support rod slidably connected to the coil pin, and the other end of the linkage support rod fixedly connected to the linkage slide plate;

[0022] When the sleeve shaft rotates under the action of the drive spindle, it drives the linkage shaft to rotate synchronously through the transmission of helical gear one. The linkage shaft drives the linkage turntable to rotate, and the linkage slide plate moves back and forth on the cleaning seat through the transmission of the coil pin and the linkage support rod. This causes the cleaning scraper to continuously scrape the surface of the cleaning scraper, thereby removing the adhering substances on the surface of the cleaning scraper.

[0023] The beneficial effects of this invention are as follows: the separation mechanism achieves stratified isolation of wastewater after sedimentation, the magnetic field position is adjusted by the drive spindle to optimize the floc formation process, and the sediment is efficiently discharged by the cleaning mechanism. It has the advantages of effectively avoiding floc disturbance when the supernatant is discharged, optimizing the floc formation process, and improving the sediment cleaning efficiency.

[0037] 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.

[0038] Please see Figures 1-11 As shown, this invention is a comprehensive wastewater treatment device for indigo production, comprising:

[0039] The treatment tank 1 serves as the main installation body for the wastewater treatment equipment. It is equipped with a drain pipe 102 at the bottom and a feed pipe 103 at the top.

[0040] The magnetic mechanism 8 is installed inside the treatment box 1. It uses magnetic powder and magnetic field to form high-density flocs of pollutants, thereby purifying the wastewater.

[0041] The cleaning mechanism 9 is located at the bottom inside the treatment box 1 and is used to scrape the settled flocs into the drain pipe 102 at the bottom of the treatment box 1 for discharge.

[0042] The partition mechanism 7 is located on the upper inner side of the treatment tank 1 and is used to separate the wastewater into layers after sedimentation to prevent the supernatant from mixing with the flocculent during the discharge process.

[0043] The drive reducer 2 is fixedly installed on the upper end of the treatment box 1. Its output end is fixedly connected to the drive spindle 3, which extends into the interior of the treatment box 1. The drive spindle 3 is used to drive the partition mechanism 7 to move up and down to adjust the position of the magnetic field, so that the wastewater flocs are formed evenly and fully. The bottom of the drive spindle 3 is fixedly connected to the cleaning mechanism 9, which is used to drive the cleaning mechanism 9 to rotate and clean and discharge the settled flocs.

[0044] The treatment tank 1 can be understood as the basic structure of the entire wastewater treatment equipment. Its main function is to provide a closed space to accommodate wastewater and various functional modules. In practical applications, the treatment tank 1 can be made of metal or high-strength plastic, such as stainless steel, which has good corrosion resistance and mechanical strength, and can adapt to the chemical environment and physical operation requirements of the wastewater treatment process. Furthermore, the positions of the drain pipe 102 and the feed pipe 103 can be adjusted according to specific process requirements. For example, the drain pipe 102 can be designed with multiple outlets to facilitate more efficient discharge of sediment.

[0045] Specifically, the magnetic mechanism 8 achieves pollutant flocculation through the interaction of magnetic powder and a magnetic field. Its core lies in utilizing the magnetic field's control over the magnetic powder, prompting the pollutants to combine with the powder to form high-density flocs. In practical applications, the magnetic mechanism 8 can generate the magnetic field using electromagnets or permanent magnets. For example, a ring-shaped electromagnet can be arranged around the outer periphery of the treatment chamber 1, or a movable permanent magnet assembly can be installed internally to dynamically adjust the magnetic field distribution. Furthermore, the selection of magnetic powder can be optimized based on the wastewater composition; for example, smaller ferrite magnetic powder can be used to improve its binding efficiency with pollutants.

[0046] Furthermore, the main function of the cleaning mechanism 9 is to scrape the settled flocs into the drain pipe 102 for discharge. Its design must ensure that flocs do not easily adhere to the scraper surface. In practical applications, the cleaning mechanism 9 can assist in cleaning the scraper surface through mechanical vibration or airflow purging. For example, a vibration motor can be installed on the scraper to reduce floc adhesion through high-frequency vibration. In addition, the shape and material of the scraper can be adjusted according to requirements. For example, an arc-shaped scraper can be used to better conform to the bottom curved surface of the treatment box 1, or a wear-resistant coating can be used to extend its service life.

[0047] Specifically, the separation mechanism 7 is used to separate the stratified wastewater, its core function being to achieve separation of the supernatant and flocculants through a physical barrier. In practical applications, the separation mechanism 7 can achieve stratification using a flexible diaphragm or a rigid baffle, for example, by using a liftable flexible diaphragm that can be deployed when needed to isolate the upper and lower liquid layers. Furthermore, the lifting and lowering of the separation mechanism 7 can be driven by a hydraulic cylinder or an electric actuator to achieve precise position control.

[0048] The innovation of this application lies in the coordinated design of the drive reducer 2 and the drive spindle 3, which enables dynamic adjustment of the magnetic field position and synchronous drive of the cleaning mechanism 9. Compared with the shortcomings of the fixed magnetic field position in the prior art, this application effectively improves the uniform formation process of flocculants by driving the magnetic mechanism 8 to move up and down through the drive spindle 3. At the same time, the rotary drive design of the cleaning mechanism 9 avoids the problems of increased mass and slowed rotation speed caused by the accumulation of flocculants on the scraper, thus maintaining a high scraping efficiency. In addition, the introduction of the partition mechanism 7 solves the problem of flocculants mixed in when the supernatant is discharged, ensuring the purity of the recovered liquid. Thus, this application systematically solves the key problems existing in the prior art through the reasonable configuration and coordinated work of various functional modules.

[0049] Furthermore, to achieve effective recovery and reuse of magnetic powder and thus reduce overall costs, a magnetic powder recovery box is specifically installed at the outlet of the sewage pipe 102. This recovery box is carefully equipped with magnetic components for adsorbing magnetic powder. After a series of treatments, the precipitate containing magnetic powder slowly falls into the recovery box through the sewage pipe 102. The magnetic components inside then perform their unique function, adsorbing the magnetic powder. Through this adsorption process, the magnetic powder is effectively separated from the precipitate and wastewater, ultimately achieving the goal of recovering and reusing the magnetic powder, thereby reducing costs throughout the production or processing process.

[0050] The working principle of this embodiment is as follows: The treatment tank 1 serves as the main installation body of the wastewater treatment equipment. A drain pipe 102 is installed at its bottom, and a feed pipe 103 is installed at its top, forming a basic operating framework that facilitates wastewater input, sediment discharge, and reagent addition. A magnetic mechanism 8 is installed inside the treatment tank 1. Through the action of magnetic powder and a magnetic field, pollutants are formed into high-density flocs, achieving wastewater purification. A cleaning mechanism 9 is installed on the inner bottom of the treatment tank 1. It scrapes the settled flocs into the drain pipe 102 at the bottom of the treatment tank 1 for discharge, effectively preventing the accumulation of flocs on the scraper, which leads to increased mass and slower rotation speed, thereby maintaining scraping efficiency.

[0051] The partition mechanism 7 is located on the upper inner side of the treatment tank 1. It separates the wastewater into layers after sedimentation, preventing the supernatant from mixing with the flocculents during discharge and ensuring the purity of the recovered liquid. The drive reducer 2 is fixedly installed on the upper end of the treatment tank 1, and its output end is fixedly connected to the drive spindle 3. The drive spindle 3 extends into the treatment tank 1 and is used to drive the partition mechanism 7 to move up and down, adjusting the magnetic field position to ensure uniform and sufficient formation of wastewater flocculents, thus solving the problem of uneven flocculation caused by a fixed magnetic field. Furthermore, the bottom of the drive spindle 3 is fixedly connected to the cleaning mechanism 9, driving the cleaning mechanism 9 to rotate and clean and discharge the settled flocculents, avoiding the cumulative effect of the scraper.

[0052] Specifically, the dual-drive function of the main drive shaft 3 enables dynamic adjustment of the magnetic field position and simultaneous scraper cleaning, optimizing the flocculation process while ensuring cleaning efficiency. The linkage between the partition mechanism 7 and the cleaning mechanism 9 ensures sedimentation stratification and sludge separation, jointly achieving efficient and pure wastewater treatment. Thus, the close cooperation of these technical features systematically solves the problems of scraper accumulation, magnetic field fixation, and supernatant contamination, achieving the expected technical results.

[0053] For further details, please refer to Figures 1-5 As shown, the magnetic mechanism 8 includes a main shaft sleeve 81 and an outer ring 82. The inner circumference of the main shaft sleeve 81 is provided with an internal thread, and the outer circumference of the drive main shaft 3 located inside the processing box 1 is provided with an external thread that mates with the internal thread. The main shaft sleeve 81 and the outer ring 82 are connected by a number of magnet blocks 83. A rectangular collar slider 84 is fixedly provided on the outer circumference of the outer ring 82. The side wall of the processing box 1 is provided with a rectangular side cavity 101 that slidably engages with the collar slider 84. The collar slider 84 is slidably disposed in the rectangular side cavity 101 along the vertical direction.

[0054] Specifically, the spindle sleeve 81 refers to a sleeve component with an internal thread structure, which can be made of metal to ensure sufficient strength and wear resistance. Its purpose is to achieve threaded engagement with the drive spindle 3 to complete the lifting motion. The outer ring 82 can be understood as a ring structure supporting the magnet block 83. It can be fixedly connected to the magnet block 83 by welding or integral molding, and its purpose is to provide a uniform and stable magnetic field environment. In practical applications, the collar slider 84 refers to a sliding component with a rectangular cross-section, which can be made of polymer or metal materials. Its purpose is to ensure that the outer ring 82 moves accurately in the vertical direction.

[0055] In detail, this scheme achieves dynamic adjustment of the magnetic field position through a threaded transmission mechanism. When the drive spindle 3 rotates, the spindle sleeve 81 undergoes axial displacement due to the threaded engagement, thereby driving the entire magnetic mechanism 8 to rise and fall. This design ensures that the magnetic field can be precisely adjusted according to the needs of different stages of wastewater treatment, avoiding problems such as insufficient floc formation or uneven distribution. Simultaneously, the magnet block 83, stably integrated into the outer ring 82, ensures the uniformity and stability of the magnetic field strength, providing ideal conditions for the full formation of flocs. Furthermore, the fit between the collar slider 84 and the rectangular side cavity 101 effectively constrains the movement trajectory of the outer ring 82, preventing it from shifting or rotating, thus maintaining the stability of the sediment layer. The aforementioned design of the magnetic mechanism 8 not only solves the problem of instability in the flocculation process caused by a fixed magnetic field but also improves the overall treatment effect through precise guidance and transmission mechanisms.

[0056] The above technical solution enables dynamic adjustment of the magnetic field position, effectively promotes the uniform generation of flocs, reduces bottom adhesion, and maintains the integrity of the floc layer during the supernatant separation stage, significantly reducing the risk of supernatant contamination.

[0057] For further details, please refer to Figures 6-7 As shown, the partition mechanism 7 includes a housing collar 71 and a main shaft collar 72. The housing collar 71 slides against the inner wall of the processing housing 1, and the main shaft collar 72 is connected to the outer periphery of the drive main shaft 3. A plurality of rotating partitions 75 are rotatably arranged between the housing collar 71 and the main shaft collar 72. One end of the rotating partition 75 is rotatably mounted on the main shaft collar 72 via a partition shaft 76, and the other end of the rotating partition 75 is rotatably mounted on the housing collar 71 via a partition shaft 76. The processing housing 1 is provided with a partition drive 6 for driving the rotating partitions 75 to rotate.

[0058] Specifically, the housing collar 71 refers to an annular structure that fits tightly against the inner wall of the processing housing 1. It can achieve sliding contact using high-precision slide rails or sealing rings to ensure the seal between the partition mechanism 7 and the housing, preventing wastewater leakage from gaps. The main shaft collar 72 can be understood as a transmission component linked to the drive shaft 3. It can achieve positional linkage through keyway connection or threaded engagement, thus responding to changing requirements at different processing stages. In practical applications, the rotating partition 75 is a dynamic partition component capable of switching between vertical and horizontal states. It achieves flexible switching through the rotational installation of the partition shaft 76, aiming to precisely separate the supernatant from flocculents and prevent disturbance of the bottom sediment when discharging the supernatant. Furthermore, the partition drive 6 is an external drive device for precisely controlling the angle of the rotating partition 75, which can adjust the partition angle through motor drive or cylinder transmission.

[0059] Specifically, this solution ensures a tight seal between the partition mechanism 7 and the tank body by sliding the tank collar 71 against the inner wall of the treatment tank 1, while also accommodating minor deformations of the inner wall of the tank to maintain stable operation. The connection design between the main shaft collar 72 and the drive main shaft 3 utilizes the existing rotation or lifting function of the drive main shaft 3 to achieve position linkage, responding to changes in the treatment stage without the need for an additional drive device. The rotating partition 75, through the rotational installation method of the partition shaft 76, maintains vertical connectivity within the tank body in the vertical state, facilitating wastewater flow and sufficient settling of flocs; when rotated to the horizontal state, it forms a physical partition layer, precisely separating the supernatant from the lower flocs. The partition drive 6 directly controls the rotation of the rotating partition 75, precisely adjusting the partition angle through an external drive source to ensure that the partition action is synchronized with the wastewater treatment process. The design of the aforementioned partition mechanism 7 effectively solves the problem of incomplete separation between supernatant and flocculants in wastewater treatment, and avoids the shortcomings of traditional fixed partition structures that cannot adapt to dynamic working conditions, thereby achieving pure recovery of supernatant and effective isolation of flocculants.

[0060] Through the above technical solution, the partition mechanism 7 not only achieves precise separation of supernatant and flocculents during wastewater treatment, but also significantly improves wastewater treatment efficiency and recovery quality by dynamically adjusting the state of the rotating partition 75.

[0061] For further details, please refer to Figures 1-7As shown, the partition drive 6 includes a partition cylinder 61 fixedly mounted on the outer wall of the processing chamber 1 and a gear shaft 66 fixedly connected to the partition shaft 76. A cylinder connecting plate 62 is fixedly connected to the output end of the partition cylinder 61. A partition slide plate 63 is fixedly mounted at the lower end of the cylinder connecting plate 62. The partition slide plate 63 slides through and extends into the interior of the processing chamber 1. A slide plate rack 64 is provided on the side end of the partition slide plate 63 inside the processing chamber 1. A drive gear 65 is fixedly mounted on the gear shaft 66 and meshes with the slide plate rack 64. When it is necessary to drive the rotating baffle 75 to rotate, the ring ring 71 drives the annular rack 73 to move up and down. The gear and rack meshing transmission drives the gear shaft 66 and the baffle shaft 76 to rotate, thereby rotating the rotating baffle 75. When it is necessary to treat wastewater, the rotating baffle 75 is in a vertical state, so that the interior of the treatment tank 1 is connected vertically. When the flocculent is generated and settles, the supernatant needs to be discharged. At this time, it is necessary to separate the supernatant and the turbid liquid. The rotating baffle 75 rotates to a horizontal state to form a partition.

[0062] Specifically, the isolation cylinder 61 is a device capable of providing linear motion driving force, which can be achieved through hydraulic or pneumatic drive. In practical applications, the isolation cylinder 61 is fixed to the outer wall of the treatment tank 1 to avoid complicating the internal structure and ensure that the driving process is not affected by the wastewater environment. The cylinder connecting plate 62 acts as a force transmission medium, its function being to efficiently transmit the thrust from the output end of the isolation cylinder 61 to the isolation slide plate 63, maintaining stable movement. The isolation slide plate 63 is a component capable of sliding within a specific track, which can be made of metal and has a corrosion-resistant surface to adapt to the wastewater environment. The slide plate rack 64 is a linear transmission component with a toothed structure, manufactured through precision machining processes to achieve precise meshing with the drive gear 65. The drive gear 65 is a gear structure capable of converting linear motion into rotary motion, which can achieve different transmission ratio requirements through module gear design.

[0063] Specifically, the above solution provides a stable and adjustable linear driving force through the isolation cylinder 61, which is transmitted to the isolation slide plate 63 via the cylinder connecting plate 62, causing the isolation slide plate 63 to reciprocate within the processing box 1. The slide plate rack 64 on the side end of the isolation slide plate 63 meshes with the drive gear 65, precisely converting linear motion into rotational motion. This conversion method effectively avoids the problem of jamming in traditional linkage mechanisms. The fixed connection structure between the gear shaft 66 and the drive gear 65 ensures that the rotational torque acts directly on the partition shaft 76, achieving instantaneous response of the rotating partition 75. When the box collar 71 drives the ring rack 73 to move up and down, the gear shaft 66 and the partition shaft 76 rotate synchronously through the gear and rack meshing transmission mechanism. This linkage method utilizes the rigidity of mechanical meshing to eliminate positioning deviations caused by transmission backlash, ensuring the consistency of the movements of all rotating partitions 75. The rotating baffle 75 remains vertical during the wastewater treatment stage, ensuring that the interior of the treatment tank 1 is open to the top and bottom to facilitate uniform settling of flocs. After settling, it rotates to a horizontal state to form a physical barrier. This state switching mechanism effectively blocks the contact path between the supernatant and the lower flocs by precisely controlling the timing of the barrier, thereby preventing flocs from mixing in when the supernatant is discharged and improving the purity of the recovered liquid.

[0064] The above technical solution solves the problem of the lack of a reliable mechanism for controlling the rotation of the rotating baffle 75, and achieves effective separation of the supernatant from the flocculent during the discharge process, thereby improving the purity of the recovered liquid.

[0065] In another alternative embodiment, given the low driving efficiency of the isolation cylinder 61, in order to drive the isolation mechanism 7 to perform on / off operations more efficiently, the linear drive of the isolation cylinder 61 is replaced with a gear and rack linear drive structure driven by a motor (not shown in the figure), achieving a more stable and efficient drive for the isolation mechanism 7. Specifically, the motor is mounted on the outer wall of the processing box 1, and a gear is fixedly mounted on the motor's output shaft. The gear is slidably connected to the outer wall of the processing box 1 and meshes with the gear. The upper end of the gear is fixedly connected to the isolation slide plate 63 for driving the lifting and lowering movement of the isolation slide plate 63.

[0066] For further details, please refer to Figures 1-7 As shown, an annular rack 73 is rotatably mounted on the outer peripheral wall of the housing collar 71. A partition gear 77 that meshes with the annular rack 73 is fixedly mounted on one end of the partition shaft 76 near the annular rack 73. The gear shaft 66 is fixedly connected to one set of partition shafts 76. When the gear shaft 66 drives one set of partition shafts 76 to rotate, the partition gear 77 mounted on the partition shaft 76 drives the annular rack 73 to rotate. The annular rack 73 drives the other sets of partition shafts 76 and the rotating partitions 75 to rotate synchronously, thereby realizing the synchronous drive of several rotating partitions 75.

[0067] Specifically, the ring rack 73 refers to a ring-shaped transmission component with a continuous tooth structure, which can be made of metal or high-strength engineering plastic. Its purpose is to ensure that multiple sets of rotating partitions 75 can move synchronously. In practical applications, the partition gear 77 can be understood as a transmission gear that cooperates with the ring rack 73. Its module and tooth profile must be strictly matched with the ring rack 73 to ensure transmission accuracy. In addition, the gear shaft 66, as a power input component, only needs to be fixedly connected to a set of partition shafts 76 to achieve overall transmission. This design simplifies the complexity of the drive source.

[0068] In detail, this solution constructs a complete transmission system by setting an annular rack 73 on the outer peripheral wall of the housing collar 71 and utilizing its meshing relationship with each set of partition gears 77. When the gear shaft 66 drives the connected partition shaft 76 to rotate, the partition gears 77 on the partition shaft 76 then drive the annular rack 73 to rotate. Due to the annular layout of the annular rack 73, its rotation can evenly transmit power to all meshing partition gears 77, thereby driving each set of partition shafts 76 to rotate synchronously. This transmission method not only avoids the additional drive components required to directly drive all partition shafts 76, but also ensures that all rotating partitions 75 maintain a consistent angle during rotation, effectively solving the problem of asynchronous rotation caused by single-point drive. At the same time, the rotational arrangement of the annular rack 73 allows it to rotate independently during the lifting and lowering of the housing collar 71, avoiding structural interference and improving the reliability of the system.

[0069] For further details, please refer to Figures 1-7 As shown, the processing box 1 is provided with a lifting mechanism 5 for driving the partition mechanism 7 to move up and down. The outer periphery of the box collar 71 is fixedly provided with a guide slide 74 that slides with the rectangular side cavity 101. The lifting mechanism 5 includes a lifting motor 51 fixedly installed on the upper end of the processing box 1. The output end of the lifting motor 51 is fixedly connected to a lifting screw 52. The outer periphery of the lifting screw 52 extends into the rectangular side cavity 101 and is threadedly connected to a screw slider 53. The screw slider 53 is fixedly connected to the guide slide 74.

[0070] In detail, this solution uses a lifting motor 51 to drive the lifting screw 52 to rotate, converting the rotational motion into the linear motion of the screw-slider 53, thereby driving the guide carriage 74 to make precise vertical displacement along the rectangular side cavity 101. This design allows the partition mechanism 7 to dynamically adjust its position according to the actual depth of flocculant sedimentation, ensuring precise separation when discharging the supernatant. Simultaneously, the cooperation between the guide carriage 74 and the rectangular side cavity 101 provides stable vertical guidance, ensuring that the partition mechanism 7 maintains a horizontal posture during lifting and lowering, avoiding separation failure due to swaying. Furthermore, the lifting motor 51 is installed at the upper end of the processing tank 1, which not only facilitates maintenance but also reduces the space occupied internally, improving the overall layout rationality of the equipment.

[0071] The above technical solution solves the problem that the fixed height of the partition mechanism 7 cannot adapt to changes in sedimentation, and realizes the function of dynamically adjusting the partition position according to the actual sedimentation situation. This effectively prevents the supernatant from mixing with flocculants, improving the reliability and efficiency of wastewater treatment. Simultaneously, this solution is linked with the rotating baffle 75 of the partition mechanism 7 to ensure a uniform separation effect at different heights, further optimizing the stratification performance in the wastewater treatment process.

[0072] For further details, please refer to Figures 8-11 As shown, the cleaning mechanism 9 includes a cleaning seat 91, a connecting bracket 92 fixedly mounted on the upper end of the cleaning seat 91, and a shaft connector 97 connected to the drive spindle 3 on the connecting bracket 92; a plurality of scraper shafts 93 are rotatably mounted on the cleaning seat 91, and a cleaning scraper 94 for scraping off sediment is fixedly connected to the lower end of the scraper shaft 93; a decontamination mechanism 95 for cleaning the surface of the cleaning scraper 94 is mounted on the cleaning seat 91, and the decontamination mechanism 95 is connected to the shaft connector 97 through a linkage mechanism 96.

[0073] In detail, this solution effectively solves the problem of efficiency reduction caused by the accumulation of flocculants on the scraper surface by integrating the decontamination mechanism 95 into the cleaning mechanism 9 and establishing a transmission relationship with the drive spindle 3 using the linkage mechanism 96. The cleaning seat 91, as the core support structure, ensures that the cleaning mechanism remains in a fixed position during operation, preventing vibration or displacement from affecting the scraping accuracy. The connecting bracket 92 and the shaft connector 97 are directly connected to the drive spindle 3, allowing the cleaning mechanism to rotate synchronously with the drive spindle 3, thereby driving the scraper shaft 93 and the cleaning scraper 94 to rotate, achieving continuous scraping of settled flocculants. Crucially, based on the rotational motion of the drive spindle 3, power is transmitted through the shaft connector 97, and the linkage mechanism 96 converts the rotational motion into the reciprocating motion of the decontamination mechanism 95. Thus, during the rotation of the cleaning scraper 94, the decontamination mechanism 95 can act on the scraper surface in real time. This design allows the decontamination mechanism 95 to remove surface residues while the scraper completes its scraping action, according to the rhythm of the scraper rotation, preventing the increase in mass and rotational resistance caused by the accumulation of flocculants. Ultimately, the solution maintained the lightweight design and stable rotation speed of the cleaning scraper 94, ensuring consistently high scraping efficiency while avoiding the need for manual intervention or downtime for cleaning, thus improving the overall operational reliability of the equipment.

[0074] The above technical solution not only solves the problem of flocculent accumulation on the surface of the cleaning scraper 94, but also realizes automated cleaning function, which significantly improves the operating efficiency and maintenance convenience of the equipment.

[0075] For further details, please refer to Figures 1-11As shown, the shaft connector 97 includes a sleeve shaft 971 fixedly mounted on the connecting bracket 92. A main shaft connecting disc 972, which is fixedly connected to the drive main shaft 3, is provided at the upper end of the sleeve shaft 971. Both the sleeve shaft 971 and the main shaft connecting disc 972 are through structures. A track wheel 98 is fixedly mounted on the upper part of the scraper shaft 93, and multiple sets of track wheels 98 are connected by a transmission track 99. The drive main shaft 3 has a shaft through hole 31 at its center, and the scraper drive shaft 4 passes through the shaft through hole 31 and is fixedly connected to the cleaning scraper 94. The drive reducer is a multi-drive unit that drives the scraper drive shaft 4 and the drive main shaft 3 to rotate respectively. The drive reducer drives the scraper drive shaft 4 to rotate, which in turn drives one set of cleaning scrapers 94 to rotate. The transmission of the transmission track 99 and the track wheel 98 drives multiple sets of cleaning scrapers 94 to rotate synchronously. The rotation of the cleaning scrapers 94 adjusts the scraping direction and angle of the scrapers, ensuring that the sediment is accurately scraped into the sewage pipe 102 and that the bottom of the treatment box 1 is completely scraped.

[0076] In detail, the above technical solution, through the through-structure design of the sleeve shaft 971 and the main shaft connecting plate 972, allows the scraper drive shaft 4 to rotate freely inside the drive main shaft 3. This structure separates the overall rotational motion of the cleaning mechanism from the angle adjustment function of the cleaning scraper 94, avoiding mutual interference between the two motions. The rotation of the scraper drive shaft 4 achieves synchronous movement of multiple sets of cleaning scrapers 94 through the cooperation of the track wheel 98 and the transmission track 99. This synchronization mechanism ensures that each cleaning scraper 94 maintains a consistent angle change during rotation, thereby effectively reducing the scraping blind spots caused by asynchronous rotation. In addition, the dynamic angle adjustment function of the cleaning scraper 94 can not only change the scraping direction in real time according to the distribution of the sediment, but also periodically change the contact state between the scraper surface and the sediment during the scraping process, thereby reducing the adhesion and accumulation of flocculants on the scraper surface and maintaining stable scraper quality and constant rotation speed. Through the above design, this technical solution not only solves the problem of flocculant accumulation caused by fixed-angle scrapers, but also significantly improves the sediment scraping efficiency and ensures a comprehensive cleaning effect at the bottom of the treatment tank 1.

[0077] For further details, please refer to Figures 8-11As shown, the cleaning mechanism 95 includes a cleaning scraper 951 slidably sleeved on the outer periphery of the cleaning scraper 94 and a linkage slide plate 955 slidably through the cleaning seat 91. The lower part of the linkage slide plate 955 is provided with a plurality of rotating grooves 954 that match the cleaning scraper 94. The rotating grooves 954 are coaxially arranged with the rotation axis of the scraper shaft 93. A connecting pin 952 is fixedly provided on the cleaning scraper 951. A connecting pin 952 is slidably connected to the rotating groove 954. A pin connecting plate 953 is rotatably connected between the two sets of connecting pins 952. The setting of the rotating groove 954 ensures that the cleaning scraper 94 can maintain a normal connection between the cleaning scraper 951 and the rotating groove 954 when rotating.

[0078] In detail, the above solution achieves continuous scraping of the adhering substances on the surface of the cleaning scraper 94 through the tight fit between the cleaning scraper 951 and the cleaning scraper 94. The sliding through-type linkage plate 955 on the cleaning seat 91 provides a stable motion path, ensuring that the cleaning scraper 951 can reciprocate along the outer circumference of the cleaning scraper 94. The coaxial setting of the rotating groove 954 and the rotating shaft of the scraper shaft 93 ensures that the cleaning scraper 951 can always maintain the correct relative position during the rotation of the cleaning scraper 94, avoiding connection failure due to rotation. The sliding connection of the connecting pin 952 in the rotating groove 954 allows the cleaning scraper 951 to automatically adjust its position according to the rotation state of the cleaning scraper 94, ensuring a gapless scraping process. The pin connecting plate 953, through the relative movement of the connecting pin 952, converts the linear reciprocating motion of the linkage plate 955 into the scraping action of the cleaning scraper 951, enhancing the removal effect of the adhering substances. The above technical solution effectively solves the problem of accumulated adhering substances on the surface of the cleaning scraper 94, maintains the scraping efficiency of the scraper, and ensures the reliable operation of the entire decontamination mechanism 95 during the working process.

[0079] For further details, please refer to Figures 8-11As shown, the linkage mechanism 96 includes a linkage seat plate 961 fixedly mounted on the connecting bracket 92. A linkage shaft 962 is rotatably mounted through the linkage seat plate 961. A second helical gear 963 is fixedly mounted at one end of the linkage shaft 962. A first helical gear 973, which meshes with the second helical gear 963, is fixedly mounted on the sleeve shaft 971. A linkage turntable 964 is fixedly mounted at the other end of the linkage shaft 962. A coil pin 965 is fixedly connected near the edge of the linkage turntable 964. A linkage support rod 966 is slidably connected to the coil pin 965. The other end of the linkage support rod 966 is fixedly connected to the linkage slide plate 955. When the sleeve shaft 971 rotates under the action of the drive main shaft 3, it drives the linkage shaft 962 to rotate synchronously through the transmission of the helical gear 973. The linkage shaft 962 drives the linkage turntable 964 to rotate. The linkage slide plate 955 is driven to slide back and forth on the cleaning seat 91 synchronously through the transmission of the coil pin 965 and the linkage support rod 966. This drives the cleaning scraper 951 to continuously scrape the surface of the cleaning scraper 94, thereby removing the adhering substances on the surface of the cleaning scraper 94.

[0080] Specifically, the aforementioned linkage mechanism 96, through the integration of gear transmission and linkage conversion mechanism, precisely transforms the rotational motion of the drive spindle 3 into the reciprocating scraping action of the cleaning scraper 951, effectively solving the problem of asynchronous removal of adhering substances. The linkage base plate 961 is fixed to the connecting bracket 92, providing a rigid support foundation for the entire mechanism and ensuring stable and reliable transmission. The linkage shaft 962 rotates through the linkage base plate 961, serving as the core transmission hub. Its design allows for free axial rotation while maintaining radial constraint, ensuring the continuity of motion transmission. The meshing connection between helical gear 2 963 and helical gear 1 973 enables the sleeve shaft 971 to efficiently and synchronously drive the linkage shaft 962 when rotating. This helical gear transmission method utilizes the tooth surface inclination angle to achieve smooth meshing and self-locking, making it particularly suitable for load fluctuations that may exist in wastewater environments. The linkage turntable 964 is fixed to the end of the linkage shaft 962, converting rotational motion into a circular trajectory output. The design of its edge-fixed coil pin 965 generates linear displacement requirements through the radius change of the circular motion. The sliding connection between the coil pin 965 and the linkage rod 966 converts the circular motion of the linkage turntable 964 into the oscillation of the linkage rod 966. This conversion mechanism is based on the crank-slider principle, ensuring a smooth and impact-free motion trajectory. The other end of the linkage rod 966 is connected to the linkage slide plate 955, converting the oscillation into linear reciprocating lifting and lowering of the linkage slide plate 955 on the cleaning seat 91. This lifting and lowering motion directly drives the cleaning scraper 951 to scrape against the surface of the cleaning scraper 94. Crucially, the entire mechanism relies entirely on the rotation of the drive shaft 3 as its power source, requiring no additional drive device, achieving strict synchronization with the rotation of the cleaning scraper 94: when the cleaning scraper 94 rotates to scrape away sediment, the linkage mechanism 96 synchronously drives the cleaning scraper 951 to reciprocate, promptly removing adhering substances and preventing accumulation that could increase scraper mass and decrease efficiency.

[0081] Furthermore, the cleaning scraper 951 is made of wear-resistant rubber, forming an elastic fit with the surface of the cleaning scraper 94. This ensures effective scraping while significantly reducing wear on the cleaning scraper 94, extending the service life of the components. The coordinated operation of the entire cleaning mechanism 95 and the linkage mechanism 96 enables dynamic, real-time, and efficient cleaning of the surface of the cleaning scraper 94, completely eliminating the tedious manual cleaning process and significantly improving the automation level and continuous operation capability of the equipment.

[0082] In another alternative embodiment, to address the issue of easy wear of the coil pin 965 and the groove structure, the sliding connection between the coil pin 965 and the linkage rod 966 is changed to a roller bearing structure. Specifically, a miniature deep groove ball bearing is installed in the pin hole of the linkage rod 966, so that the coil pin 965 cooperates with the inner ring of the bearing, converting sliding friction into rolling friction, which can reduce the wear rate. At the same time, the material of the rotating groove 954 is upgraded to high manganese steel and subjected to carburizing and quenching treatment, increasing the surface hardness to HRC58-62. Combined with the PTFE-coated connecting pin 952, sliding wear is further reduced, and the maintenance cycle is extended.

[0083] Furthermore, all transmission components of the linkage mechanism 96 are treated with sealed bearings and anti-corrosion coatings, effectively resisting the erosion of corrosive media in the wastewater environment, extending the service life of the equipment, and reducing maintenance costs. Specifically, the sealed bearings adopt a double-lip structure design. The outer lip is used to prevent sewage from seeping into the bearing, while the inner lip is filled with high-performance grease to form secondary protection, effectively isolating the bearing balls and raceways from corrosive components such as sulfides and acidic substances in the wastewater environment. The anti-corrosion coating uses a nano-level ceramic composite coating, which forms a dense protective layer on the surface of the transmission components through plasma spraying. Its porosity is less than 0.5%, and its hardness reaches HV1200 or higher. It can not only resist long-term immersion in highly corrosive media such as chloride ions and dye intermediates, but also has excellent wear resistance, which can reduce coating wear caused by flocculent scraping. In addition, a polytetrafluoroethylene (PTFE) self-lubricating bushing is used on the sliding mating surface of the coil pin 965 and the linkage support rod 966. This bushing has both a low coefficient of friction and chemical corrosion resistance. While achieving oil-free lubrication, it avoids the problem of traditional grease easily emulsifying and failing in sewage environment, and further ensures the long-term stable operation of the linkage mechanism under complex working conditions.

[0084] Through the above technical solution, the linkage mechanism 96 not only solves the problem of coordinated rotation between the sludge scraper 951 and the cleaning scraper 94, but also significantly improves the stability of equipment operation. Meanwhile, since the entire mechanism relies entirely on the rotation of the drive shaft 3 as its power source, no additional drive device is required, simplifying the equipment structure and reducing manufacturing costs and maintenance difficulty. Furthermore, the combination of helical gear transmission and linkage conversion mechanism enables the linkage mechanism 96 to operate stably in wastewater environments for extended periods, demonstrating strong adaptability and high reliability.

[0085] The foregoing has provided a detailed description of one embodiment of the present invention, but this description is merely a preferred embodiment and should not be construed as limiting the scope of the invention. All equivalent variations and modifications made within the scope of the claims of this invention should still fall within the patent coverage of this invention.
