Description

Technical Field

[0001] The utility model relates to the technical field of seawater aquaculture tail water treatment, in particular to a sedimentation and filtration treatment device for seawater aquaculture tail water. Background Art

[0002] Seawater aquaculture is an important aquaculture method. Seawater aquaculture cultivates various seafood products, such as fish, shellfish, shrimps, etc. by utilizing the nutrients in seawater. Tail water refers to the wastewater that has enriched nutrients and organic matter after passing through aquaculture ponds or facilities. The aquaculture tail water contains a large amount of organic matter such as residual baits and feces, as well as nutrients such as nitrogen and phosphorus dissolved in water. If these substances are directly discharged without effective treatment, it will cause water eutrophication, and then trigger ecological disasters such as red tides, seriously threatening the stability of the nearshore marine ecosystem. Therefore, it is necessary to filter and treat the tail water to meet the discharge standard or reuse standard.

[0003] The existing seawater aquaculture tail water has the following problems during treatment: 1. The tail water of cultured fish is usually initially filtered by a filter plate. However, in the existing technology, feces and impurities in the tail water are easily retained on the surface of the filter plate, often resulting in blockage of the filter plate during the tail water filtration process; 2. Most of the existing aquaculture wastewater sedimentation ponds on the market are open-air structures, resulting in the wastewater odor seriously affecting the surrounding residents and the environment. Summary of the Utility Model

[0024] Refer to Figures 1-4 , an embodiment of a sedimentation and filtration treatment device for seawater aquaculture tail water of the present utility model includes a sedimentation tank 1. A filter cylinder 9 is disposed through the middle of the upper part of the sedimentation tank 1. One end of the outer side of the filter cylinder 9 is provided with a liquid inlet 7 through which the liquid inlet 7 is connected to the external seawater aquaculture tail water discharge pipeline, so that the aquaculture tail water enters the inside of the filter cylinder 9. An installation frame 6 is fixedly connected to the filter cylinder 9. One end of the upper part of the installation frame 6 is fixedly connected with a motor 10. The output end of the motor 10 penetrates through the filter cylinder 9 and is fixedly connected with a rotating rod 19 inward;

[0025] One end of the inner side of the filter cartridge 9 is fixedly connected with a fixing frame 15, the other end of the fixing frame 15 is fixedly connected with a connecting shell 16, the other end of the rotating rod 19 penetrates through the connecting shell 16 and is fixedly connected with a first bevel gear 11 inward. A filter screen 14 is fixedly connected inside the filter cartridge 9, and the filter screen 14 is arranged below the connecting shell 16. A rotating shaft 17 is rotatably connected inside the connecting shell 16, a second bevel gear 23 is fixedly connected to the rotating shaft 17, and the second bevel gear 23 meshes with the first bevel gear 11. One end of the lower part of the rotating shaft 17 is fixedly connected with a cleaning brush 18, and the cleaning brush 18 is used to clean the filter screen 14. The internal filter screen 14 can filter impurities and feces in the tail water, and the filtered tail water can directly enter the sedimentation tank 1 for sedimentation. In order to prevent the filter screen 14 from being blocked during use, the motor 10 is started to drive the rotating shaft 17 and the first bevel gear 11 to rotate. Under the meshing action, the second bevel gear 23 can drive the rotating rod 19 to rotate, realizing the circular motion of the cleaning brush 18, thereby cleaning the filter screen 14 and avoiding the influence of impurities above on the use of the filter screen 14. The fixing frame 15 at the other end of the connecting shell 16 can fix it to ensure that the connecting shell 16 can be stably used inside the filter cartridge 9. Secondly, the two bevel gears installed inside the filter cartridge 9 are subjected to various treatments such as waterproofing and anti-corrosion to ensure their service life in the filter cartridge 9;

[0026] The bottom of the filter cartridge 9 is fixedly connected with a bracket 5, and the other end of the bracket 5 is fixedly connected above the sedimentation tank 1. The device can be stably supported through the bracket 5. A cover plate 8 is installed above the filter cartridge 9. A liquid discharge port 13 is arranged through one end of the outer side of the sedimentation tank 1. The cover plate 8 adopts a detachable structure and can be opened in the subsequent process to clean the internal filter screen 14, improving its use effect;

[0027] A feed port 12 is arranged through one end of the upper part of the sedimentation tank 1, and an odor removal pipe 4 is arranged through the other end of the upper part of the sedimentation tank 1. The other end of the odor removal pipe 4 is provided with an odor remover 2, and a fan 3 is installed on the top of the odor remover 2. After the fan 3 is started, the odor gas in the sedimentation tank 1 enters the odor remover 2 through the odor removal pipe 4. First, impurities are filtered through the internal pretreatment layer, the gas flows through the activated carbon adsorption layer, and about 60%-80% of the odor molecules are adsorbed. And a chemical washing layer is configured, and the medicament spray further neutralizes acidic / alkaline gases. After the treated gas is detected to meet the standards (such as H2S < 10 ppm, NH3 < 5 ppm), it can be discharged through the exhaust port;

[0028] A guide plate 20 is fixedly connected to the inside of the sedimentation tank 1. A sludge pipe 21 is arranged outwardly through the bottom of the guide plate 20 through the sedimentation tank 1. Solenoid valves 22 are installed inside the sludge pipe 21, the drain port 13 and the deodorization pipe 4. The sludge pipe 21 can be connected to a sludge pump. By starting the sludge pump, the sludge settled at the bottom of the sedimentation tank 1 can be discharged outward through the sludge pipe 21. At the same time, the solenoid valve 22 can control the opening and closing operations of multiple pipelines to ensure stable operation between the multiple pipelines.

[0029] Working principle: When in use, the staff connects the liquid inlet 7 to the seawater aquaculture tail water pipeline, and passes the aquaculture tail water into the interior of the filter cylinder 9. The impurities and feces in the tail water can be filtered through the internal filter screen 14, and the filtered tail water can directly enter the sedimentation tank 1 for sedimentation. In order to prevent the filter screen 14 from being blocked during use, the start motor 10 drives the rotating shaft 17 and the bevel gear 11 to rotate. Under the action of meshing, the bevel gear 23 can drive the rotating rod 19 to rotate, realizing the circular motion of the cleaning brush 18, thereby cleaning the filter screen 14 and preventing the impurities above from affecting the use of the filter screen 14. The staff adds flocculant to the interior of the sedimentation tank 1 through the feed port 12, so that the tail water inside is precipitated. The precipitated tail water can be discharged outwardly through the discharge port 13, and the remaining sludge is connected to the sludge pipe 21 and the sludge pump, so that it can be pumped out through the sludge pipe 21, thereby achieving the effect of sedimentation and filtration.

[0030] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the present invention.
