[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This microfiltration aquaculture recirculating water treatment device allows aquaculture water to enter the machine through the inlet pipe. The water first undergoes primary filtration through filter element number one. The filtered water then passes through a first electrically controlled valve to filter element number two for fine filtration. A drive motor rotates the screw conveyor, simultaneously rotating the connecting parts and scraper elements number one and two. The scraper element number one rotates against the outer walls of the secondary filter elements of filter elements number one and two, scraping off impurities trapped on the filter screen. These scraped impurities are then pushed to the drain pipe by the screw conveyor and discharged. This achieves dynamic linkage between the scraper and the screw conveyor, continuously cleaning the filter screen and the inner wall of the machine, preventing filter clogging, ensuring long-term stable operation of the device, and reducing the frequency of manual cleaning.

[0012] 2. This microfiltration aquaculture recirculating water treatment device uses a water quality sensor on the outer surface of the outlet pipe as its core monitoring element. It collects key water quality parameters of the effluent after dual filtration in real time and transmits the monitored electrical signals synchronously to a controller on the outer surface of the machine. The controller has a built-in data processing module and control logic to analyze the received water quality parameters. The cover is secured to the outer surface by screw blocks, forming a threaded fit with a screw groove on the outer surface of the machine. During installation, rotating the cover causes the screw blocks to gradually screw in along the screw groove. The self-locking property of the threads ensures a tight fit between the cover and the machine, making disassembly and assembly convenient and facilitating subsequent maintenance and replacement of internal filter elements, scrapers, and other components.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1: Please refer to Figures 1-4. A microfiltration aquaculture recirculating water treatment device includes a body 1, a cover 4, and a drive motor 17. The drive motor 17 and the cover 4 are both located on the outer surface of the body 1. A first filter element 9 and a second filter element 10 are fixedly installed on the outer surface of the cover 4. An inlet pipe 2 and a drain pipe 3 are fixedly connected to the outer surface of the body 1. An outlet pipe 5 is fixedly connected to the outer surface of the cover 4 and is fixedly connected to the second filter element 10. A connector 13 is fixedly installed on the outer surface of the first filter element 9. A first electrically controlled valve 11 is installed at the bottom of the first filter element 9, and a second electrically controlled valve 12 is installed at the bottom of the second filter element 10. The first filter element 9 is connected to the first solenoid valve 11, and the second filter element 10 is connected to the sewage pipe 3 through the second solenoid valve 12. The outer surface of the connector 13 is fixedly installed with the first scraper 14 and the second scraper 15. The first scraper 14 is rotatably connected to the first filter element 9 and the second filter element 10, and the second scraper 15 is rotatably connected to the inner wall of the machine body 1. The output end of the drive motor 17 is fixedly installed with the screw conveyor 16, which is rotatably connected to the sewage pipe 3 in a sealed manner. The connector 13 is set on the outer surface of the screw conveyor 16, and the connector 13 is rotated by the drive motor 17.

[0017] Specifically, after the aquaculture water enters the machine body 1 through the inlet pipe 2, it first undergoes primary filtration through the first filter element 9 to intercept large particles of impurities. The filtered water then enters the second filter element 10 through the first electric control valve 11 for fine filtration, removing tiny suspended solids and colloids. The drive motor 17 drives the screw conveyor 16 to rotate, simultaneously causing the connecting part 13 and the first scraper 14 and the second scraper 15 to rotate synchronously. The first scraper 14 rotates against the outer wall of the secondary filter elements of the first and second filters 9 and 10 respectively, scraping off the impurities trapped on the filter screen. The second scraper 15 rotates against the inner wall of the machine body 1 to clean the residual dirt in the machine body 1. The scraped impurities are pushed to the sewage pipe 3 for discharge through the screw conveyor 16.

[0018] In the embodiment: the first scraper component 14 includes a first annular scraper and a second annular scraper. The first annular scraper is rotatably attached to the outer wall of the first filter component 9, and the second annular scraper is rotatably attached to the outer wall of the second filter component 10. Both the first scraper and the second scraper component 15 are arc-shaped scrapers.

[0019] Specifically, when the drive motor 17 drives the connector 13 to rotate, it drives the first annular scraper and the second annular scraper of the first scraper component 14 to rotate synchronously. The first annular scraper is tightly rotated and attached to the outer wall of the first filter element 9, and the second annular scraper is tightly rotated and attached to the outer wall of the second filter element 10. During the rotation, the intercepted impurities attached to the surface of the first filter element 9 and the secondary filter element are continuously scraped off, so that the impurities are removed from the filter screen surface and fall into the spiral conveying auger 16 area below.

[0020] In this embodiment: a sealed bearing is fitted at the bottom of the screw conveyor 16, and the sealed bearing is rotatably connected to the inner wall of the sewage pipe 3. The connecting piece 13 is a cross-shaped bracket structure. The first scraper piece 14, the second scraper piece 15 and the screw conveyor 16 are all detachably connected to the connecting piece 13 by bolts.

[0021] Specifically, the sealed bearing at the bottom of the screw conveyor 16 forms a sealed rotating connection with the inner wall of the sewage pipe 3. While ensuring the smooth rotation of the screw conveyor 16 to push out impurities, it effectively prevents sewage leakage in the sewage pipe 3, ensuring the airtightness of the device operation. The sealed rotating design of the sealed bearing avoids the risk of sewage leakage, ensures the operational stability of the device in the process of treating aquaculture circulating water, and prevents equipment failure or secondary water pollution caused by leakage.

[0022] Working principle: The drive motor 17 and the cover 4 are both located on the outer surface of the body 1. A first filter element 9 and a second filter element 10 are fixedly installed on the outer surface of the cover 4. A water inlet pipe 2 and a sewage outlet pipe 3 are fixedly connected to the outer surface of the body 1. A water outlet pipe 5 is fixedly connected to the outer surface of the cover 4, and the water outlet pipe 5 is also fixedly connected to the second filter element 10. A connector 13 is fixedly installed on the outer surface of the first filter element 9. A first solenoid valve 11 is located at the bottom of the first filter element 9, and a second solenoid valve 12 is located at the bottom of the second filter element 10. The second filter element 10 and... Filter element 9 is connected to the first solenoid valve 11, and filter element 10 is connected to the sewage pipe 3 via the second solenoid valve 12. A scraper 14 and a scraper 15 are fixedly mounted on the outer surface of the connector 13. The scraper 14 is rotatably connected to filter element 9 and filter element 10, and the scraper 15 is rotatably connected to the inner wall of the machine body 1. A screw conveyor 16 is fixedly mounted on the output end of the drive motor 17. Because the screw conveyor 16 is rotatably connected to the sewage pipe 3 in a sealed manner, the connector 13 is positioned on the screw conveyor 16. The outer surface of the screw conveyor 16, and the connecting part 13 rotates via the drive motor 17. After the aquaculture water enters the machine body 1 through the water inlet pipe 2, it first passes through the first filter element 9 for initial filtration to intercept large particles of impurities. The filtered water then enters the second filter element 10 through the first electronic control valve 11 for fine filtration to remove tiny suspended solids and colloids. The drive motor 17 drives the screw conveyor 16 to rotate, simultaneously driving the connecting part 13 and the first scraper part 14 and the second scraper part 15 to rotate synchronously. The first scraper part 14 respectively adheres to the first filter element 9 and the second filter element 10. The outer wall of the secondary filter element rotates, scraping off the impurities trapped on the filter screen; the second scraper 15 rotates against the inner wall of the machine body 1, cleaning the residual dirt on the machine body 1. The scraped-off impurities are pushed to the sewage pipe 3 by the screw conveyor 16 and discharged. Compared with related technologies, the micro-filter aquaculture circulating water treatment device provided by this utility model has the following beneficial effects: it achieves the linkage between the dynamic scraper and the screw conveyor 16, continuously cleaning the dirt on the filter screen and the inner wall of the machine body 1, avoiding filter screen clogging, ensuring long-term stable operation of the device, and reducing the frequency of manual disassembly and cleaning.

[0023] Example 2: Please refer to Figures 1-4. A water quality sensor 6 is installed on the outer surface of the water outlet pipe 5, a controller is installed on the outer surface of the body 1, a screw block 8 is fixedly installed on the outer surface of the cover 4, a screw groove 7 is opened on the outer surface of the body 1, and the cover 4 and the body 1 are threadedly connected to the screw block 8 through the screw groove 7.

[0024] Specifically, the water quality sensor 6 on the outer surface of the outlet pipe 5 serves as the core monitoring element, collecting key water quality parameters of the water after dual filtration in real time. The monitored electrical signals are synchronously transmitted to the controller on the outer surface of the main body 1. The controller has a built-in data processing module and control logic to analyze the received water quality parameters. The cover 4, secured by screw blocks 8 on its outer surface, forms a threaded fit with the screw groove 7 on the outer surface of the main body 1. During installation, rotating the cover 4 causes the screw blocks 8 to gradually screw into the screw groove 7. The self-locking property of the threads ensures a tight fit between the cover 4 and the main body 1, facilitating easy assembly and disassembly and providing convenience for subsequent maintenance and replacement of internal components such as filters and scrapers.

[0025] In this embodiment: a sealing ring is provided at the threaded connection between the cover 4 and the body 1. The sealing ring is made of fluororubber, and the threads of the screw block 8 and the screw groove 7 are fine threads.

[0026] Specifically, the screw block 8 of the cover 4 and the screw groove 7 of the body 1 are fitted with fine-pitch threads. The fine-pitch threads have a small pitch and high thread profile accuracy. When the cover 4 is rotated, the screw threads can form a tight engagement. The self-locking property of the threads makes the cover 4 and the body 1 fit together firmly, preventing the connection from loosening due to vibration during operation. The fluororubber sealing ring at the threaded connection is squeezed between the mating surfaces of the cover 4 and the body 1. Fluororubber itself has excellent elasticity and corrosion resistance. After being squeezed, it will fully fill the tiny gaps between the fine-pitch threads, forming an elastic sealing barrier to block the flow of aquaculture water inside the body 1 to the outside.

[0027] In the embodiment: the first solenoid valve 11 at the bottom of the first filter element 9 is a duckbill control valve, and the second solenoid valve 12 at the bottom of the second filter element 10 is a cone control valve. Both are electric proportional valves. The controller is electrically connected to the water quality sensor 6, the drive motor 17, the first solenoid valve 11, and the second solenoid valve 12, and the controller has a built-in timing module.

[0028] Specifically, the water quality sensor 6 on the outer surface of the outlet pipe 5 serves as the core monitoring element, collecting key water quality parameters of the water after dual filtration in real time and synchronously transmitting the monitored electrical signals to the controller on the outer surface of the unit 1. The controller has a built-in data processing module, control logic, and timing module, forming a complete electrical connection with the water quality sensor 6, drive motor 17, first electric control valve 11, and second electric control valve 12, constructing a multi-dimensional control system. When the water quality sensor 6 detects that the outlet water parameters do not meet the preset standards, the controller immediately analyzes the cause of the deviation and triggers a precise adjustment command. For large particulate impurities intercepted by the first filter element 9, the controller controls the duckbill electric proportional valve to adjust the opening, optimizing the rate of water flow from the first filter element to the second filter element 10. For the fine filtration stage of the second filter element 10, the conical electric proportional valve regulates the sewage discharge volume and the proportion of filtered water retention. At the same time, the controller links the drive motor 17 to adjust the speed, so that the scraper scraping efficiency and the auger impurity discharge efficiency are adapted to the current filtration load. If the water quality meets the standards, the controller will periodically fine-tune the opening of the two electrically controlled valves and the motor speed according to the preset program of the timing module to ensure the continuous and stable operation of the filtration system.

[0029] Working principle: A water quality sensor 6 is installed on the outer surface of the water outlet pipe 5, a controller is installed on the outer surface of the body 1, and a screw block 8 is fixedly installed on the outer surface of the cover 4. At the same time, a screw groove 7 is opened on the outer surface of the body 1. The cover 4 and the body 1 are connected by a screw block 8 through the screw groove 7. The water quality sensor 6 on the outer surface of the water outlet pipe 5 serves as the core monitoring element, which collects key water quality parameters of the water after double filtration in real time and transmits the monitored electrical signals synchronously to the controller on the outer surface of the body 1. The controller has a built-in data processing module and control logic to analyze the received water quality parameters. The screw block 8 fixed on the outer surface of the cover 4 forms a threaded engagement structure with the screw groove 7 opened on the outer surface of the body 1. During installation, the screw block 8 is gradually screwed into the screw groove 7 by rotating the cover 4. The self-locking property of the thread is used to achieve a tight fit between the cover 4 and the body 1. Compared with related technologies, the micro-filter aquaculture circulating water treatment device provided by this utility model has the following beneficial effects: it achieves convenient disassembly and assembly, and provides convenience for subsequent maintenance and replacement of internal filter elements, scrapers and other components.
