Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of circulating water aquaculture, especially to a filter device for circulating water aquaculture convenient to clean. BACKGROUND

[0002] Circulating water aquaculture is a modern aquaculture mode, which reduces water consumption and pollution discharge by recycling water resources and reducing water replacement frequency. In this mode, the filter device plays a crucial role in removing impurities such as leftover feed and feces from the aquaculture water, maintaining water quality, and providing a good growing environment for the aquaculture organisms. Therefore, the performance and quality of the filter device directly affect the efficiency of aquaculture and the health of the aquaculture organisms.

[0003] In the circulating water aquaculture industry, the cleaning convenience and filtration efficiency of the filter device, as a core component, have a decisive impact on the overall effectiveness and continuous operation of the aquaculture system. In particular, in the core step of cleaning the filter device, the existing filter device for circulating water aquaculture, such as the one disclosed in utility model patent CN210419527U, although it improves the oxygen enrichment uniformity through specific structural design, gradually exposes a series of obvious limitations and technical problems in actual use.

[0004] The existing technology faces the prominent problem of inconvenient operation when cleaning the filter device. Because the filter screen in the traditional filter device has an angle with the vertical direction, and the internal structure of the filter device is relatively complex, multiple components need to be disassembled during cleaning, which is tedious and time-consuming, not only reducing the cleaning efficiency, but also increasing the labor intensity of the aquaculture personnel. At the same time, the inconvenience during cleaning may also lead to incomplete cleaning, with residues accumulating in the filter device, thereby affecting the filtration effect and aquaculture water quality. In addition, the accumulation of residues due to the inconvenience of cleaning in the existing filter device during long-term use may also cause water quality deterioration, disease of the aquaculture organisms, and other problems, thereby increasing the aquaculture risk. More seriously, these problems not only significantly increase the aquaculture cost, but also may pose potential risks to the growth of the aquaculture organisms and the overall quality of the aquaculture system. Therefore, in view of the many deficiencies in the existing technology, we urgently need an innovative filter device for circulating water aquaculture to solve these problems. UTILITY MODEL CONTENTS

A connecting pipe is fixedly connected to the bottom of the support frame, and the bottom of the connecting pipe is connected to several water outlet pipes. An annular plate is provided on the lower inner side of the cylindrical body, and a filter plate is fixedly connected to the top of the annular plate. A brush is fixedly connected to the outer wall of the annular plate, and a rotating rod is fixedly connected to the top of the filter plate. A drive motor is fixedly connected to one side of the top of the connecting pipe by bolts, and the top of the rotating rod passes through the connecting pipe through a bearing sleeve and is connected to the output shaft of the drive motor for transmission.

[0008] Preferably, a pump body is fixedly connected to one side of the outer wall of the cylinder by bolts, and a hose is connected to the outlet of the pump body, with one end of the hose connected to the top side of the connecting pipe.

The brushes, during rotation and up-and-down movement, thoroughly clean impurities from the inner wall of the cylinder and the filter plates, significantly improving cleaning efficiency and convenience. The connections between components are tight and reliable. Bolt connections and bearing sleeve drives ensure the stability and durability of the device. The selection of hydraulic cylinders and a drive motor also guarantees the device's power source and transmission effect. The filter plates, as the core component of the filtration system, are rationally designed and have high filtration efficiency. Through the evenly distributed water and the filtration action of the filter plates, impurities in the water are effectively removed, maintaining water quality. This provides a good growth environment for aquaculture organisms, improving breeding efficiency and the health of the organisms, and effectively reducing the frequency of water changes and cleaning costs during the breeding process. Furthermore, by improving breeding efficiency and the health of the aquaculture organisms, breeding costs and economic risks are further reduced.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0024] Reference Figures 1-6 A filter device for recirculating aquaculture systems that is easy to clean includes a cylindrical body 1. A top plate 2 is fixedly connected to the top of the cylindrical body 1, and a hydraulic cylinder 3 is fixedly connected to one side of the top of the top plate 2 by bolts. A support frame 7 is provided inside the cylindrical body 1, and the output shaft of the hydraulic cylinder 3 passes through the top of the top plate 2 and is fixedly connected to the top of the support frame 7. A connecting pipe 8 is fixedly connected to the bottom of the support frame 7, and the bottom of the connecting pipe 8 is connected to several water outlet pipes 11. An annular plate 14 is provided on the lower inner side of the cylindrical body 1. The annular plate 14 can bear the weight of the filter plate 10 and the brush 12, as well as the force generated during rotation. Its outer wall is connected to the brush. 12 is fixedly connected to ensure that the brush 12 can closely fit the inner wall of the cylinder 1 for cleaning. The top of the annular plate 14 is fixedly connected to the filter plate 10, and the outer wall of the annular plate 14 is fixedly connected to the brush 12. The brush 12 is made of soft and durable bristles, which can closely fit the inner wall of the cylinder 1 for thorough cleaning, ensuring the long-term stable operation of the filtration device and good filtration effect. The top of the filter plate 10 is fixedly connected to the rotating rod 15. The top side of the connecting pipe 8 is fixedly connected to the drive motor 9 by bolts, and the top of the rotating rod 15 passes through the connecting pipe 8 through the bearing sleeve and is connected to the output shaft of the drive motor 9 for transmission.

[0025] Furthermore, a pump body 4 is fixedly connected to one side of the outer wall of the cylinder 1 by bolts, and a hose 5 is connected to the outlet of the pump body 4. One end of the hose 5 is connected to the top of the connecting pipe 8. When water to be filtered is introduced, the pump body 4 starts and pumps the water into the connecting pipe 8 through the hose 5. Then, the water is evenly sprayed onto the filter plate 10 through the outlet pipe 11. The arrangement of the pump body 4 and the hose 5 realizes the automatic pumping of water, improves the automation level of the filtration device, reduces the cumbersome manual operation, and also ensures that the water can enter the filtration system stably and continuously, thereby improving the filtration efficiency.

[0026] Furthermore, a scraper 13 is fixedly connected to one side of the bottom of the annular plate 14. As the drive motor 9 drives the annular plate 14 to rotate, the scraper 13 also rotates to scrape off the impurities at the bottom of the cylinder 1. The scraper 13 effectively removes the impurities that may accumulate at the bottom of the cylinder 1, avoids the accumulation of impurities at the bottom of the cylinder 1, ensures the cleanliness and efficient operation of the filtration system, and also extends the service life of the filtration device.

[0027] Furthermore, a valve body 6 is connected to the lower side of the cylinder 1. During the filtration process or after cleaning, the water or impurities inside the cylinder 1 can be discharged through the valve body 6. The valve body 6 provides a convenient drainage and impurity removal channel, making the cleaning and maintenance of the filtration device more convenient, while also ensuring the flexibility and reliability of the filtration system.

[0028] Furthermore, the connection between the output shaft of the hydraulic cylinder 3 and the top plate 2 is a sliding connection.

[0029] Furthermore, the outer brush 12 of the annular plate 14 is attached to the inner wall of the cylinder 1. The attachment of the brush 12 to the inner wall of the cylinder 1 ensures thoroughness and effectiveness of cleaning, avoids the residue and accumulation of impurities on the inner wall of the cylinder 1, and maintains the cleanliness and efficient operation of the filtration system.

[0030] In summary:

[0031] First, the device uses a cylindrical body 1 as its main structure. A top plate 2, fixedly connected to the top of the cylindrical body 1, ensures the stability and sealing of the entire device. On one side of the top plate 2, a hydraulic cylinder 3, bolted to one side, provides strong power support for subsequent cleaning. The support frame 7, located inside the cylindrical body 1, is a key load-bearing component of the filtration system. It is fixedly connected to the output shaft of the hydraulic cylinder 3, and the extension and retraction of the hydraulic cylinder 3 drives the support frame 7 to move up and down within the cylindrical body 1. A connecting pipe 8, fixedly connected to the bottom of the support frame 7, connects to several water outlet pipes 11. When the water to be filtered is automatically pumped into the connecting pipe 8 through the pump body 4 and the hose 5, the water is evenly sprayed onto the filter plates 10 through the water outlet pipes 11. The filter plates 10 are located on the lower inner side of the cylindrical body 1 and are fixedly connected inside the cylindrical body 1 by an annular plate 14. They are responsible for removing residual feed, feces, and other impurities from the water, maintaining water quality. During the filtration process, impurities gradually accumulate on the filter plates 10, requiring periodic cleaning. At this time, the drive motor 9 is started, and its output shaft is connected to the annular plate 14 via the rotating rod 15, driving the annular plate 14 and its filter plates 10 and brushes 12 to rotate together. The brushes 12 are fitted against the inner wall of the cylinder 1, and during rotation, they thoroughly clean the inner wall of the cylinder 1, removing attached impurities. Simultaneously, to ensure a comprehensive cleaning of the inner wall of the cylinder 1, the hydraulic cylinder 3 moves the entire support frame 7 downwards, allowing the brushes 12 to contact all parts of the inner wall of the cylinder 1, ensuring thorough cleaning. Furthermore, the scraper 13, fixedly connected to one side of the bottom of the annular plate 14, rotates along with the drive motor 9 as the annular plate 14 rotates, scraping away impurities at the bottom of the cylinder 1, effectively preventing the accumulation of impurities at the bottom of the cylinder 1. When the filtration process is complete or cleaning is required, the water or impurities inside the cylinder 1 can be discharged through the valve body 6 connected to the lower side of the cylinder 1, providing a convenient drainage and impurity removal channel, making the cleaning and maintenance of the filtration device more convenient. The connection between the output shaft of hydraulic cylinder 3 and top plate 2 is a sliding connection. This design reduces friction and wear during movement, improves the working efficiency and service life of hydraulic cylinder 3, and also ensures the stable movement of the support frame 7 within the cylinder 1. The pump body 4 and hose 5 enable automatic water pumping, improving the automation level of the filtration device; the scraper 13 effectively removes impurities that may accumulate at the bottom of cylinder 1; the valve body 6 provides convenient drainage and impurity removal channels; the sliding connection design improves the working efficiency and service life of hydraulic cylinder 3; and the close fit between the brush 12 and the inner wall of cylinder 1 ensures thorough and effective cleaning. These designs collectively ensure the cleanliness and efficient operation of the filtration system, extend the service life of the filtration device, reduce aquaculture costs, and improve aquaculture efficiency and the health of aquatic organisms.
