Description

Technical Field

[0001] This utility model relates to the field of filtration equipment technology, specifically to a water filtration device based on aquaculture. Background Technology

[0002] Aquaculture relies on clean water to maintain the health of its organisms, and water filtration is a core element in ensuring stable water quality. Physical filtration removes suspended solids such as uneaten feed and feces, reducing toxins like ammonia nitrogen and nitrite produced from the decomposition of organic matter. Biological filtration utilizes nitrifying bacteria to convert harmful substances into harmless nitrates, balancing the ecosystem. Simultaneously, filtration inhibits the proliferation of pathogenic microorganisms, reducing the risk of disease. A recirculating water system combined with high-efficiency filtration can significantly improve water resource utilization, prevent eutrophication pollution, and ensure optimal stocking density and survival rates.

[0003] Currently, patent publication number CN220088316U discloses a filtration device for aquaculture seedling raising water. This device primarily involves a motor driving a threaded rod to rotate after the filter plate has been filtering for an extended period. The threaded rod is then threadedly connected to a movable plate, and the movable plate slides against a sliding rod, causing the movable plate to reciprocate within a slag storage tank. This movement is facilitated by brushes to clean the filter holes on the filter plate. However, because the brushes are located at the bottom of the filter plate, the threaded rod drives the brushes to scrub the filter holes, causing the scrubbed dirt to fall onto the brushes. Since the brushes cannot be disassembled, the accumulated debris on them increases over time, leading to unpleasant odors and difficulty in cleaning. Utility Model Content

[0004] The purpose of this invention is to provide a water filtration device for aquaculture, which solves the technical problem that after long-term use, the accumulated debris on the brushes increases, causing the brushes to easily develop odors and become difficult to clean.

[0005] The technical solution of this utility model is implemented as follows:

[0006] A water filtration device for aquaculture includes a fixed base, a filter cylinder on the top of the fixed base, symmetrical water pipes connected to the outer periphery of the filter cylinder, a boss inside the filter cylinder, multiple grooves inside the boss, fixed columns connected to the grooves, multiple filter plates detachably connected between the fixed columns, a support block on the top of the filter cylinder, the tops of the fixed columns and filter plates connected to the bottom surface of the support block, and a protective component connected to the top of the support block.

[0007] A further technical solution is that the bottom of the fixed post is provided with an extension post, the lower half of the extension post is provided with an external thread, the groove is provided with an internal thread, the extension post extends into the boss, and the external thread can be connected with the internal thread.

[0008] A further technical solution is that a clamping block is provided between the fixed column and the boss, the extension column can pass through the clamping block and connect to the boss, and the top surface and bottom surface of the clamping block contact the bottom surface of the fixed column and the top surface of the boss, respectively.

[0009] A further technical solution is that the pressing block includes a top adhesive, an intermediate layer and a bottom adhesive, which are tightly connected in sequence. The top surface of the top adhesive contacts the bottom surface of the fixing column, and the bottom surface of the bottom adhesive contacts the top surface of the boss. The intermediate layer is a solid body.

[0010] A further technical solution is that the filter plate is a mesh plate, the fixing column is provided with a first embedding groove, both sides of the mesh plate are embedded in the first embedding groove and fixedly connected to the fixing column, and the fixing column is in close contact with the inner wall of the filter cylinder.

[0011] A further technical solution is that a filter frame is provided between the fixed columns, and a second embedding groove is provided inside the fixed column, and the filter frame is embedded in the second embedding groove and fixedly connected to the fixed column.

[0012] A further technical solution is that the protective component includes a cover top, the cover top is provided with a plurality of elliptical holes, a fixing sleeve is fitted on the outer peripheral surface of the filter cylinder, a connecting block is fixedly provided, and the elliptical holes and the connecting block are fixedly connected by a connector.

[0013] A further technical solution is that a bottom block is provided on the outer periphery of the boss, and the bottom block is connected to the inner bottom surface of the filter cylinder by a nut.

[0014] A further technical solution is that the water pipe includes a water supply pipe and a water inlet pipe, which are staggered and connected to the side wall of the filter cylinder.

[0015] The beneficial effects of this utility model are as follows:

[0016] 1. After filtering sewage for a long time, the protective component is opened, and the support block is separated from the top of the filter cylinder, making it easy to remove the filter plate from the fixed column. After removing the filter plate, the fixed column is separated from the boss by rotating it. Finally, the fixed column and filter plate are pulled out for external cleaning. Without the obstruction of the fixed column and filter plate, it is also convenient to clean the inside of the filter cylinder, increasing the cleaning area of ​​the filtration device. This solves the technical problem that after long-term use, the accumulated garbage on the brush increases, causing the brush to easily develop odors and be difficult to clean.

[0017] 2. When using a clamping block, after the fixed column and the boss are stably connected, the clamping block's elastic expansion makes the clamping block more compact, preventing sewage from leaking between the fixed column and the boss and reducing the sewage filtration effect.

[0018] 3. Using a filter rack in conjunction with a filter plate for wastewater filtration further improves the wastewater filtration effect. Attached Figure Description

[0024] To better understand the technical content of this utility model, specific embodiments are provided below, and the utility model will be further described in conjunction with the accompanying drawings.

[0025] See Figures 1 to 4 This utility model provides a water filtration device for aquaculture, including a fixed base 1, a filter cylinder 2 on the top of the fixed base 1, water pipes symmetrically connected to the outer periphery of the filter cylinder 2, a boss 3 inside the filter cylinder 2, a plurality of grooves 4 inside the boss 3, a fixed column 5 connected to the grooves 4, a plurality of filter plates 6 detachably connected between the fixed columns 5, a support block 7 on the top of the filter cylinder 2, the top of the fixed columns 5 and the filter plates 6 connected to the bottom surface of the support block 7, and a protective component connected to the top of the support block 7.

[0026] It should be noted that the fixed base 1 is used to fix the filter in a designated position to ensure stable operation of the filter device. The support block 7 is used to prevent the filter plate 6 from detaching from the fixed column 5. The support block 7 is frictionally connected to the filter cylinder 2.

[0027] Specifically, after filtering sewage for a long time, the protective component is opened, and the support block 7 is separated from the top of the filter cylinder 2, making it easy to remove the filter plate 6 from the fixing column 5. At the same time, after the filter plate 6 is removed, the fixing column 5 is separated from the boss 3 by rotating the fixing column 5. Finally, the fixing column 5 and the filter plate 6 are pulled out for external cleaning. Without the obstruction of the fixing column 5 and the filter plate 6, it is also convenient to clean the inside of the filter cylinder 2, increasing the cleaning area of ​​the filtration device. This solves the technical problem that after long-term use, the accumulated garbage on the brush increases, causing the brush to easily develop odors and be difficult to clean.

[0028] In this embodiment, the bottom of the fixed post 5 is provided with an extension post 8, the lower half of the extension post 8 is provided with an external thread, the groove 4 is provided with an internal thread, the extension post 8 extends into the boss 3, and the external thread can be connected with the internal thread.

[0029] An extension post 8 is provided at the bottom of the fixed post 5. The external thread of the extension post 8 is used to connect stably with the internal thread inside the groove 4, which also facilitates subsequent disassembly.

[0030] Furthermore, a clamping block 9 is provided between the fixed column 5 and the boss 3. The extension column 8 can pass through the clamping block 9 and connect with the boss 3. The top and bottom surfaces of the clamping block 9 are in contact with the bottom surface of the fixed column 5 and the top surface of the boss 3, respectively.

[0031] The diameter of the clamping block 9 is equal to the inner diameter of the filter cylinder 2. Due to the elasticity of the clamping block 9, it is compressed inside the filter cylinder 2 and smoothly embedded in the inner wall of the filter cylinder 2. When the extension block passes through the clamping block 9, the bottom surface of the fixing column 5 is in close contact with the top surface of the clamping block 9, and the top surface of the boss 3 is in close contact with the bottom surface of the clamping block 9. Through the elastic expansion of the clamping block 9, the clamping block 9 becomes more compact, preventing sewage from leaking between the fixing column 5 and the boss 3 and reducing the sewage filtration effect.

[0032] Furthermore, the pressing block 9 includes a top adhesive 10, an intermediate layer 11, and a bottom adhesive 12. The top adhesive 10, the intermediate layer 11, and the bottom adhesive 12 are tightly connected in sequence. The top surface of the top adhesive 10 contacts the bottom surface of the fixing post 5, and the bottom surface of the bottom adhesive 12 contacts the top surface of the boss 3. The intermediate layer 11 is a solid body.

[0033] Top adhesive 10 and bottom adhesive 12 cover the top and bottom surfaces of the solid body. Top adhesive 10, bottom adhesive 12 and the surrounding solid body are elastic, which makes it easy to fit tightly with the inner circumferential surface of the filter cylinder 2 when it is inserted into the filter cylinder 2.

[0034] In this embodiment, the filter plate 6 is a mesh plate, and the fixing post 5 is provided with a first embedding groove 13. Both sides of the mesh plate are embedded in the first embedding groove 13 and fixedly connected to the fixing post 5. The fixing post 5 is in close contact with the inner side wall of the filter cylinder 2.

[0035] The mesh plate is used to facilitate the filtration of impurities in the sewage. After a long period of filtration, the filter plate 6 needs to be pulled out through the first embedding groove 13 for easy subsequent cleaning.

[0036] The filter plate 6 and the fixed column 5 form a quadrangular prism shape, which makes the fixed column 5 in close contact with the inner wall of the filter cylinder 2, thereby improving the all-round filtration effect.

[0037] In this embodiment, a filter frame 14 is provided between the fixed columns 5, and a second embedding groove 15 is provided inside the fixed column 5. The filter frame 14 is embedded in the second embedding groove 15 and fixedly connected to the fixed column 5.

[0038] The filter frame 14 is cross-shaped. After the first filtration by the filter plate 6, the filter frame 14 performs a second filtration to improve the filtration effect.

[0039] In this embodiment, the protective component includes a cover 16, which has a plurality of elliptical holes 17. A fixing sleeve 18 is fitted on the outer peripheral surface of the filter cylinder 2, and a connecting block 19 is fixedly provided. The elliptical holes 17 and the connecting block 19 are fixedly connected by a connector 20.

[0040] When filtering wastewater, the top cover is fixed to the filter cylinder 2 via connector 20 to prevent wastewater from being sprayed out of the filter cylinder 2. Connector 20 allows for easy disassembly of the top cover and filter cylinder 2, facilitating the removal of the filter plate 6. Connector 20 is a bolt.

[0041] In this embodiment, a bottom block 21 is provided on the outer periphery of the boss 3, and the bottom block 21 is connected to the inner bottom surface of the filter cylinder 2 by a nut 22.

[0042] In order to clean the boss 3, a bottom block 21 is provided on the outer periphery of the boss 3, which is connected to the inner bottom surface of the filter cylinder 2 by a nut 22, thereby completing the disassembly function and further improving the all-round cleaning of the filter cylinder 2.

[0043] In this embodiment, the water pipe includes a water supply pipe 23 and a water inlet pipe 24, which are staggered and connected to the side wall of the filter cylinder 2.

[0044] The inlet pipe 24 is located at the bottom right side of the filter cylinder 2, and the outlet pipe 23 is located at the top left side of the filter cylinder 2. The inlet is used to receive wastewater, while the outlet pipe 23 is used to output the filtered water. Wastewater enters the filter cylinder 2 at the bottom and is filtered by the filter plate 6. Most of the clean water is located at the top of the filter cylinder 2, resulting in high-quality clean water output.

[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
