Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture technology, and in particular to a seawater circulation filtration device for marine aquaculture farms. Background Technology

[0002] In marine aquaculture, water quality management is crucial for ensuring the healthy growth of aquatic products. As the core equipment for maintaining water cleanliness, the filtration efficiency and self-cleaning ability of the circulating filtration device directly affect the stability of the system and maintenance costs. However, existing marine circulating filtration devices mostly rely on manual periodic disassembly and cleaning, requiring frequent shutdowns by operators. This is not only time-consuming and labor-intensive, but also inefficient. Furthermore, manual cleaning often fails to thoroughly remove fine impurities and biological deposits adhering to the filter plate surface, easily creating cleaning blind spots. This leads to filter pore blockage, increased water flow resistance, and consequently, reduced filtration efficiency, affecting the stable operation of the entire marine circulation system. Therefore, we propose a marine circulating filtration device for marine aquaculture farms. Utility Model Content

[0003] The main objective of this invention is to provide a seawater circulation filtration device for marine aquaculture farms, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A seawater circulation filtration device for a marine aquaculture farm includes a filter box. An inlet pipe communicating with the interior of the filter box is inserted through one side of the filter box. A drain pipe communicating with the interior of the filter box is inserted through the side of the filter box away from the inlet pipe. A small water pump is fixedly installed inside the filter box, and the outlet of the small water pump is connected to the drain pipe. A first filter plate and a second filter plate are fixedly installed in the middle of the filter box. A cleaning mechanism for cleaning the first and second filter plates is provided inside the filter box. A control panel is fixedly installed at the front end of the filter box.

[0006] An clearance groove is provided in the middle of the upper inner wall of the filter box, and a sliding groove is provided at the beginning of the upper inner wall of the clearance groove;

[0007] The cleaning mechanism includes a forward and reverse motor fixedly installed on the outside of the filter box, a transmission screw connected to the output end of the forward and reverse motor and movably installed in the slide groove, a slider threadedly connected to the transmission screw and slidably connected in the slide groove, a support assembly fixedly connected to the lower end of the slider and located in the clearance groove, and a cleaning assembly installed on the support assembly.

[0008] Preferably, the support assembly includes a U-shaped support frame fixedly connected to the lower end of the slider and slidably connected in the clearance groove, and two extension arms symmetrically connected to the U-shaped support frame.

[0009] By adopting the above technical solution, the U-shaped support frame and the extension arm form a stable support structure, ensuring that the cleaning components remain balanced during operation, while facilitating the layout and installation of the driven cleaning unit, thereby improving the overall structural strength and operational stability.

[0010] Preferably, the cleaning assembly includes an active cleaning unit movably installed in the middle of the U-shaped support frame, and two driven cleaning units symmetrically installed on the two extension arms, each of which is drively connected to the active cleaning unit.

[0011] By adopting the above technical solutions, multi-point synchronous cleaning operations can be achieved, the cleaning coverage area can be expanded, and the cleaning efficiency can be improved. At the same time, the roller brush linkage control can be realized through the transmission connection, reducing the number of driving components, simplifying the control system, and improving equipment reliability.

[0012] Preferably, the active cleaning unit includes a drive motor fixedly installed at the lower end of the slider and located within the U-shaped support frame, an active rotating rod fixedly connected to the output end of the drive motor and movably interlocked with the U-shaped support frame, an active gear fixedly connected to the active rotating rod and located within the U-shaped support frame, and an active cleaning roller brush fixedly connected to the active rotating rod and located below the U-shaped support frame.

[0013] By adopting the above technical solution, the drive motor directly drives the active roller brush to rotate, and the power output is achieved in conjunction with the transmission gear. The structure is compact and the response is fast, which can efficiently remove impurities from the surface of the filter plate and ensure filtration efficiency.

[0014] Preferably, the driven cleaning unit includes a driven rotating rod movably connected to the extension arm, a driven gear fixedly connected to the driven rotating rod and meshing with the driving gear, and a driven cleaning roller fixedly connected to the driven rotating rod and at the same height as the driving cleaning roller brush.

[0015] By adopting the above technical solution, the driven and active roller brushes can be operated synchronously through gear meshing transmission, forming a two-way cleaning structure, which enhances the cleaning effect, avoids filter pore clogging, and improves the continuity and stability of the filtration device operation.

[0016] Preferably, the driven cleaning roller brush and the active cleaning roller brush have the same structure, and the driven cleaning roller brush and the active cleaning roller brush are located on both sides of the first filter plate or the second filter plate, respectively.

[0017] By adopting the above technical solution, two roller brushes rotate synchronously in opposite directions on the upper and lower sides of the filter plate, forming a convection cleaning effect, effectively removing attached substances, thoroughly removing impurities, and improving cleaning efficiency and filtration performance.

[0018] Preferably, the pore diameter of the filter plate No. 1 is larger than that of the filter plate No. 2.

[0019] By adopting the above technical solution, a two-stage filtration system is formed, which first intercepts large particulate impurities and then removes fine suspended solids, thereby improving filtration efficiency and water purification capacity, extending the service life of the filter plates, and adapting to the needs of complex seawater environments.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The forward and reverse motor drives the transmission screw to rotate in both directions, causing the slider connected to it to move horizontally back and forth in the groove. This, in turn, controls the U-shaped support frame and cleaning components installed below to move synchronously. This structure ensures that the active cleaning roller and the driven cleaning roller cover the entire filter surface area of ​​the No. 1 and No. 2 filter plates during operation, avoiding cleaning blind spots, effectively removing impurities attached to the surface of the filter plates, and improving cleaning efficiency and filtration stability.

[0022] 2. During the cleaning process, the drive motor drives the active rotating rod to rotate, and the active gear fixed on it rotates accordingly. At the same time, it drives the driven gears on both sides, so that the driven cleaning rollers mounted on the extension arm rotate synchronously but in the opposite direction to the active cleaning rollers. This reverse rotation structure can form a convection cleaning effect on the upper and lower sides of the filter plate, effectively peeling off and dispersing the impurity particles attached to the filter holes, preventing clogging, improving the water flow capacity, and thus ensuring the long-term stable operation of the filtration device. It is suitable for seawater environments with high impurity content. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Please see Figure 1-4 This utility model provides a technical solution:

[0032] A seawater circulation filtration device for a marine aquaculture farm includes a filter box 1. An inlet pipe 2, which communicates with the interior of the filter box 1, is inserted through one side of the filter box 1. A drain pipe 3, which communicates with the interior of the filter box 1, is inserted through the side of the filter box 1 away from the inlet pipe 2. A small water pump 4 is fixedly installed inside the filter box 1. The outlet of the small water pump 4 is connected to the drain pipe 3. A first filter plate 5 and a second filter plate 6 are fixedly installed in the middle of the filter box 1. A cleaning mechanism 7 for cleaning the first filter plate 5 and the second filter plate 6 is provided inside the filter box 1. A control panel 8 is fixedly installed at the front end of the filter box 1.

[0033] In this embodiment, a clearance groove 11 is provided in the middle of the upper inner wall of the filter box 1, and a sliding groove 12 is provided at the beginning of the upper inner wall of the clearance groove 11; the cleaning mechanism 7 includes a forward and reverse motor 71 fixedly installed on the outside of the filter box 1, a transmission screw 72 connected to the output end of the forward and reverse motor 71 and movably installed in the sliding groove 12, a slider 73 threadedly connected to the transmission screw 72 and slidably connected in the sliding groove 12, a support assembly 74 fixedly connected to the lower end of the slider 73 and located in the clearance groove 11, and a cleaning assembly 75 installed on the support assembly 74; the support assembly Component 74 includes a U-shaped support frame 741 fixedly connected to the lower end of slider 73 and slidably connected in relief groove 11, and two extension arms 742 provided and symmetrically connected to the U-shaped support frame 741; cleaning assembly 75 includes an active cleaning unit 751 movably installed in the middle of U-shaped support frame 741, and two driven cleaning units 752 provided and symmetrically installed on two extension arms 742, both of which are drively connected to the active cleaning unit 751; the filter hole diameter on filter plate 5 is larger than the filter hole diameter on filter plate 6.

[0034] The above scheme utilizes a forward and reverse motor 71 to drive the transmission screw 72 to rotate in both directions, thereby causing the slider 73, which is threadedly connected to it, to perform horizontal reciprocating motion within the slide groove 12. This, in turn, controls the synchronous movement of the U-shaped support frame 741 and the cleaning assembly 75 installed below it. This structure ensures that the active cleaning unit 751 and the driven cleaning unit 752 cover the entire filter surface area of ​​the first filter plate 5 and the second filter plate 6 during operation, avoiding blind spots in cleaning, effectively removing impurities attached to the surface of the filter plates, and improving cleaning efficiency and filtration stability.

[0035] In this embodiment, the active cleaning unit 751 includes a drive motor 7511 fixedly installed at the lower end of the slider 73 and located within the U-shaped support frame 741, an active rotating rod 7512 fixedly connected to the output end of the drive motor 7511 and movably connected to the U-shaped support frame 741, an active gear 7513 fixedly connected to the active rotating rod 7512 and located within the U-shaped support frame 741, and an active cleaning roller brush 7514 fixedly connected to the active rotating rod 7512 and located below the U-shaped support frame 741; and a driven cleaning unit 752. It includes a driven rotating rod 7521 that is movably connected to the extension arm 742, a driven gear 7523 that is fixedly connected to the driven rotating rod 7521 and meshes with the driving gear 7513, and a driven cleaning roller brush 7522 that is fixedly connected to the driven rotating rod 7521 and is located at the same height as the active cleaning roller brush 7514; the driven cleaning roller brush 7522 and the active cleaning roller brush 7514 have the same structure, and the driven cleaning roller brush 7522 and the active cleaning roller brush 7514 are located on both sides of the first filter plate 5 or the second filter plate 6, respectively.

[0036] Through the above scheme: the drive motor 7511 drives the active rotating rod 7512 to rotate, and the active gear 7513 fixed on it rotates accordingly, and simultaneously drives the driven gears 7523 on both sides, so that the driven cleaning roller brush 7522 installed on the extension arm 742 rotates synchronously but in the opposite direction to the active cleaning roller brush 7514. This reverse rotation structure can form a convection cleaning effect on the upper and lower sides of the filter plate, effectively peeling off and dispersing the impurity particles attached to the filter holes, preventing clogging, improving the water flow capacity, thereby ensuring the long-term stable operation of the filtration device, which is suitable for seawater environments with high impurity content.

[0037] It should be noted that this utility model is a seawater circulation filtration device for aquaculture farms. To prevent clogging during use, the seawater to be treated first enters the filter box 1 through the inlet pipe 2. Since the pore size of the first filter plate 5 is larger than that of the second filter plate 6, the water flows through the two filter plates for graded filtration. First, the first filter plate 5 with larger pore size intercepts larger particles of impurities, and then the second filter plate 6 further removes smaller suspended solids, thus achieving multi-stage purification. Subsequently, the filtered seawater is pumped to the drain pipe 3 by a small water pump 4 to complete the entire circulation filtration process, ensuring that the aquaculture water remains clean. To prevent the filter plates from clogging and affecting the filtration efficiency, the device is equipped with a cleaning mechanism 7. This cleaning mechanism 7 is driven by a forward and reverse motor 71 to rotate the transmission screw 72, which drives the slider 73 connected to it to move horizontally back and forth along the slide groove 12, thereby controlling the active cleaning unit 751 installed on the U-shaped support frame 741 and The driven cleaning unit 752 moves laterally to cover the entire filter plate area. At the same time, the drive motor 7511 starts, driving the active rotating rod 7512 to rotate. The active gear 7513 and the active cleaning roller brush 7514 are fixed on the active rotating rod. The active gear 7513 meshes with two driven gears 7523, causing the driven cleaning roller brush 7522 mounted on the extension arm 742 to rotate synchronously in the opposite direction. Since the active cleaning roller brush 7514 and the driven cleaning roller brush 7522 rotate in opposite directions and are located on both sides of the first filter plate 5 and the second filter plate 6, respectively, this design allows the roller brush to efficiently clean the impurities adhering to the surface of the filter plate while moving laterally and rotating in the opposite direction. This not only improves cleaning efficiency but also effectively prevents filter pore clogging and ensures the continuous and stable operation of the filtration system. The entire cleaning process does not require manual intervention and can be automatically controlled by setting the time through the control panel 8, realizing intelligent and continuous seawater circulation filtration operation.

[0038] It should be noted that, in order to prevent the driven gear 7523 and the driving gear 7513 located in the filter box 1 from rusting due to long-term contact with moisture, the present invention has adopted the following measures:

[0039] First, waterproof sealing rings or sleeves are installed at the positions where the driving rod 7512 and the driven rod 7521 pass through the U-shaped support frame 741 and the extension arm 742. These seals can effectively prevent moisture from seeping into the gear transmission system, reducing the chance of gears coming into direct contact with water, thereby reducing the risk of rust. At the same time, the driving gear 7513 and the driven gear 7523 are made of highly corrosion-resistant materials, such as stainless steel, engineering plastics, or metal materials with special anti-corrosion treatment. These materials not only have good mechanical properties, but also resist the corrosion of salt in seawater, extending their service life.

[0040] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
