Detailed Implementation

[0021] 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.

[0022] Please see Figures 1-4 This utility model discloses a coarse filtration device for aquaculture water, including a support leg 1, a top fixing plate 2 welded to the top of the support leg 1, a box body 3 bolted to the top of the top fixing plate 2, a side plate 4 connected to one side of the outer wall of the box body 3, an oxygen tank 5 placed at the top of the side plate 4, a pressure pump 6 connected to the top of the oxygen tank 5 through an external flange, and a transmission pipe 7 penetrating one side of the outer wall of the pressure pump 6.

[0023] One end of the transmission pipe 7 passes through the box 3, and the end of the transmission pipe 7 away from the box 3 is fixedly connected to the medicine box 8, which is located on one side of the box 3, below the side plate 4.

[0024] Specifically, this aquaculture water coarse filtration device uses support legs 1 and a top fixed plate 2 as the basic support structure. The housing 3 serves as the core processing unit. Components such as side plates 4, oxygen tanks 5, pressure pumps 6, and medicine tanks 8 constitute the oxygenation and chemical addition system. Filter pipes 10, connecting pipes 9, pressure plates 12, partitions 11, and top filter plates 13 form the filtration structure. The inlet pipe 15, outlet 14, transfer pump 16, baffle 19, pumping pipe 20, debris outlet 21, and water outlet 18 form the water flow transmission and impurity separation system. All parts cooperate to achieve functions such as coarse filtration, oxygenation, chemical addition, and impurity separation of aquaculture water, effectively improving the water quality. The side plates 4 are fixedly connected to one side of the outer wall of the housing 3, providing a platform for the oxygen tank 5, which stores oxygen. The top of the oxygen tank is connected to the pressure pump 6 via an external flange, which serves as the power source. The oxygen source 6 pressurizes the oxygen in the oxygenation tank 5 and delivers it to the aquaculture water in the tank 3 through the transmission pipe 7. During the aquaculture process, dissolved oxygen is continuously consumed due to the respiration of aquatic organisms and the activity of microorganisms in the water. The pressurization pump 6 works continuously to replenish oxygen in the aquaculture water in a timely manner, ensuring that the dissolved oxygen content in the water is maintained at a suitable level to meet the survival needs of aquatic organisms. One end of the transmission pipe 7 passes through the tank 3, and the other end is fixedly connected to the medicine tank 8. The medicine tank 8 is used to store water quality conditioning agents, such as disinfectants and water quality improvers. When water quality needs to be adjusted, the agents are delivered to the tank 3 along with the oxygen through the transmission pipe 7. The design of the transmission pipe 7 allows oxygen and agents to be evenly distributed in the aquaculture water, improving the efficiency and effect of oxygenation and agent addition, helping to improve the water quality of the aquaculture water, prevent aquatic diseases, and promote their healthy growth.

[0025] In this embodiment, multiple filter tubes 10 are fixedly connected to both sides of the inner bottom end face of the box 3 by a fixing bracket 17. The top ends of the multiple filter tubes 10 are corresponding to the connecting pipe 9, and one end of the connecting pipe 9 is fixedly connected to one end of the transmission pipe 7.

[0026] Specifically, multiple filter tubes 10 are fixedly connected to both sides of the inner bottom end face of the tank 3 by a fixing bracket 17. The filter tubes 10 are made of filter material with large pores, which can intercept larger particles of impurities in the water, such as leftover food and fish excrement. The connecting pipe 9 is fixedly connected to one end of the transmission pipe 7 and corresponds to the top of the filter tube 10. When the aquaculture water enters the tank 3, under the action of water pressure, the water flows upward through the pores of the filter tube 10, and impurities are intercepted on the outside of the filter tube 10. The filtered water is mixed with oxygen and chemicals in the transmission pipe 7 through the connecting pipe 9 to achieve preliminary filtration and water quality regulation.

[0027] In this embodiment, a pressure plate 12 is fixedly connected to the inner wall of the housing 3 at the top side of the multiple filter tubes 10. A partition plate 11 is snapped into the bottom of each pressure plate 12, and a top filter plate 13 is fixedly connected between the two partition plates 11 near the top.

[0028] Specifically, the pressure plate 12 is fixedly connected to the inner wall of the box 3 at the top of the filter tube 10, and is used to fix the partition 11 and the top filter plate 13. The partition 11 is snapped into the bottom of the pressure plate 12, dividing the interior of the box 3 into different areas, guiding the water flow along a predetermined path, avoiding short-circuiting of the water flow, and ensuring that the aquaculture water can be fully filtered through the filter tube 10 and the top filter plate 13. The top filter plate 13 is fixedly connected between the two partitions 11 at the top position. Its pore size t is smaller than that of the filter tube 10, which can perform secondary filtration on the aquaculture water after the initial filtration by the filter tube 10, further removing smaller particles of impurities in the water, improving the filtration effect, and ensuring that the aquaculture water flowing out of the box 3 is cleaner.

[0029] In this embodiment, two water inlet pipes 15 pass through the side of the box 3 away from the side plate 4. One end of the two water inlet pipes 15 is fixedly connected to the output port 14, and the end of the two water inlet pipes 15 away from the output port 14 is clamped to the transfer pump 16.

[0030] Specifically, two inlet pipes 15 pass through the side of the tank 3 away from the side panel 4. One end is fixedly connected to the outlet 14, and the other end is connected to the transfer pump 16. The transfer pump 16 acts as a water flow power device, drawing aquaculture water from the outside through the pumping pipe 20 and transporting it to the inlet pipe 15. Then, it is injected into the tank 3 through the outlet 14. The design of the outlet 14 allows the aquaculture water to enter the tank 3 evenly, avoiding excessive water flow that could impact the filtration structure and ensuring the stability of the filtration process.

[0031] In this embodiment, a baffle 19 is fixedly connected to the input end of the transfer pump 16, and a pumping pipe 20 is fixedly connected to one side of the outer wall of the baffle 19.

[0032] Specifically, the baffle 19 is fixedly connected to the input end of the transfer pump 16 to block large debris from entering the transfer pump 16 and prevent the debris from damaging the transfer pump 16. The pumping pipe 20 is connected to the transfer pump 16 and is used to transport aquaculture water.

[0033] In this embodiment, a debris outlet 21 is fixedly connected to one side of the bottom end of the pumping pipe 20, and the debris outlet 21 is located on one side of the transfer pump 16.

[0034] Specifically, the debris outlet 21 is fixedly connected to one side of the bottom of the pumping pipe 20, located on one side of the transfer pump 16. During the process of pumping aquaculture water, larger debris is intercepted by the baffle 19 and can be discharged through the debris outlet 21, preventing debris from entering the housing 3 and affecting the filtration effect. It also facilitates cleaning of debris and reduces subsequent maintenance work.

[0035] In this embodiment, the bottom end of the box 3 is fixedly connected to the water outlet 18, and the bottom end of the water outlet 18 is penetrated by the top fixing plate 2.

[0036] Specifically, the outlet 18 is fixedly connected to the bottom of the tank 3. The aquaculture water, after being filtered by the filter pipe 10 and the top filter plate 13, and treated with oxygen and added medicine, is discharged from the tank 3 through the outlet 18 and returned to the aquaculture area, providing a clean, oxygen-rich and water-conditioned aquaculture environment for aquatic organisms.

[0037] The working principle and usage process of this utility model are as follows: During use, the transfer pump 16 is started. The transfer pump 16 draws aquaculture water from the aquaculture area through the pumping pipe 20. During the drawing process, larger debris is intercepted by the baffle 19 and discharged through the debris outlet 21. The aquaculture water continues to flow along the pumping pipe 20 into the inlet pipe 15, and is evenly injected into the tank 3 through the outlet 14. At this time, larger particles of impurities in the aquaculture water undergo preliminary impurity separation after passing through the top filter plate 13. Under the action of water pressure, the aquaculture water injected into the tank 3 flows downwards and enters the filter tube 10 through the pores of the partition 11. The filter tube 10 intercepts larger particles of impurities in the water, such as residual feed and fish excrement. After the filtered water enters the filter tube 10, it is mixed with oxygen and medicine in the transfer pipe 7 through the connecting pipe 9 and added to the initial filtered water in the filter tube 10 to ensure the water quality of the initial filtered water. During the process, the pores on the partition 11 guide the water flow along a predetermined path, ensuring that the aquaculture water can be fully filtered through the filter pipe 10 and the top filter plate 13, improving filtration efficiency and effect. The pressure pump 6 works continuously, pressurizing the oxygen in the oxygenation tank 5 and then delivering it to the tank 3 through the transmission pipe 7. At the same time, depending on the water quality, the medicine in the medicine tank 8 also enters the tank 3 along with the oxygen through the transmission pipe 7. The oxygen and medicine are evenly distributed in the transmission pipe 7 and the aquaculture water in the tank 3, replenishing dissolved oxygen, regulating water quality, preventing aquatic diseases, and promoting their healthy growth. After filtration, oxygenation, and medicine treatment, the aquaculture water is discharged from the outlet 18 at the bottom of the tank 3 and returned to the aquaculture area. As the device continues to operate, the aquaculture water is continuously circulated to maintain stable water quality and provide a good living environment for aquatic organisms.
