[0038] Reference Figures 1 to 3The present application provides an aquaculture sewage discharge device, which is arranged in a breeding pond for use. The aquaculture sewage discharge device comprises a tray 1, a perforated plate 2, a water inlet pipe 3 and a drain pipe 4. The tray 1 comprises a bottom plate 11 and a rib 12, the bottom plate 11 is provided with a water inlet 13 and a drain port 14, and the rib 12 is provided with an escape port 15. The perforated plate 2 is provided with mesh holes, the perforated plate 2 is obliquely connected between the bottom plate 11 and the rib 12, and the cover is arranged above the drain port 14. The water inlet pipe 3 is connected to the bottom of the water inlet 13, and the drain pipe 4 is connected to the bottom of the drain port 14.
[0039] In detail, the retaining edge 12 surrounds the edge of the bottom plate 11 and extends upward from the edge of the bottom plate 11. The bottom plate 11 can be set to a circular, square or other shape. The bottom plate 11 of the tray 1 is immersed in the water body, the top of the retaining edge 12 can extend out of the water surface, and the perforated plate 2 is at least partially immersed in the water body to prevent dirt or dead fish from leaking back into the breeding pond from the top of the retaining edge 12. The upper end of the water inlet pipe 3 is fixedly connected to the water inlet 13, and the upper end of the drain pipe 4 is fixedly connected to the drain outlet 14.
[0040] The feces, leftover bait and other waste in the water body are mainly concentrated at the bottom of the breeding pond. The lower end of the water inlet pipe 3 extends to the bottom of the water body in the breeding pond, and can extend to the center of the bottom of the breeding pond. The waste at the bottom of the water body can enter the tray 1 from the water inlet pipe 3, pass through the mesh of the orifice plate 2, and then be discharged from the drain pipe 4, so that the waste inside the breeding pond is quickly gathered and discharged. Compared with the traditional breeding pond method of burying pipes underground, the water inlet pipe 3 of the aquaculture sewage discharge device of the present application is easy to maintain and clean, and can eliminate the risk of accumulated pollution.
[0041] The drain pipe 4 is used to suck out the sewage in the tray 1. After the sewage is decontaminated, it can be discharged back to the breeding pond for recycling, which can continuously maintain the cleanliness of the water body, reduce the water consumption in breeding, and reduce costs. When applied to high-density eel breeding, the greater the water circulation volume, the better the sewage suction effect.
[0042] The water in the breeding pond contains leftover bait, feces, weak fish, dead fish, etc., which are sucked into the tray 1 through the water inlet pipe 3, and then enter the drain pipe 4 after passing through the mesh of the perforated plate 2. Weak fish, dead fish or other larger wastes are intercepted by the perforated plate 2 and stranded on the perforated plate 2 along the direction of the water flow, and can be picked up by the breeding personnel during patrol.
[0043] The escape port 15 on the tray 1 can provide an escape place for the live fish that stray into the tray 1, and the live fish that enter the tray 1 can return to the breeding pond through the escape port 15. The perforated plate 2 is arranged obliquely to prevent the intercepted dead fish and weak fish from completely blocking the mesh of the perforated plate 2 and affecting the drainage of the drain pipe 4. The lower end of the drain pipe 4 can be connected to a sewage treatment device, which absorbs water through the drain pipe 4 to filter and disinfect the sewage.
[0044] The aquaculture sewage discharge device of the present application integrates the functions of sewage discharge and dead fish removal, has an appropriate installation height, and can control the water level inside the breeding pond while discharging sewage through water circulation, thereby greatly simplifying the internal structure of the breeding pond and reducing breeding costs.
[0045] Especially for eels with vigorous feeding, a lot of leftover bait and feces are produced. The aquaculture sewage discharge device of the present application can remove dirt and dead fish in time, keep the water clean, and provide a good foundation for high-density circulating water culture of eels, and is suitable for use in eel circulating water culture ponds.
[0046] The water inlet 13 and the drain outlet 14 of the bottom plate 11 may be pipe interfaces extending downward, and the connection methods between the water inlet 13 and the water inlet pipe 3 and the drain outlet 14 and the drain pipe 4 include but are not limited to bonding, plugging, threaded connection, snap connection, integral injection molding, etc. The water inlet 13 and the water inlet pipe 3 and the drain outlet 14 and the drain pipe 4 should be sealed to ensure sewage discharge efficiency.
[0047] The orifice plate 2 can be connected to the bottom plate 11 and the retaining edge 12 by bonding, clamping, fastener connection, integral injection molding, etc. The tray 1 and / or the orifice plate 2 and / or the water inlet pipe 3 and / or the drain pipe 4 can be made of plastic materials such as PVC, PP, etc., which are non-toxic and corrosion-resistant, and are conducive to reducing costs.
[0048] In some embodiments of the present application, one side edge of the orifice plate 2 is connected to the bottom plate 11, and the other edge of the orifice plate 2 is connected to the retaining edge 12. The water inlet 13 and the drain 14 are arranged at intervals, one side edge of the orifice plate 2 is connected to the position between the water inlet 13 and the drain 14 of the bottom plate 11, the orifice plate 2 extends obliquely from the bottom plate 11 to the top of the drain 14, and the other edge of the orifice plate 2 is connected to the retaining edge 12 and is lower than the top of the retaining edge 12. The shape of the orifice plate 2 is adapted to the shape of the bottom plate 11 and the retaining edge 12. The bottom plate 11, the retaining edge 12 and the orifice plate 2 surround the drain 14, and the water must pass through the orifice plate 2 to enter the drain 14.
[0049] like Figure 2 In the specific implementation, the bottom plate 11 is configured as a circular structure, the side of the orifice plate 2 connected to the bottom plate 11 is a straight edge, and the side of the orifice plate 2 connected to the retaining edge 12 is an arc edge.
[0050] In another specific embodiment, the bottom plate 11 can be configured as a square structure, and the orifice plate 2 is a square structure, wherein one edge is connected to the bottom plate 11 , and the other three sides are connected to the retaining edge 12 .
[0051] In some embodiments of the present application, Figure 2 and Figure 3As shown, the escape port 15 on the tray 1 is arranged on the side of the water inlet 13 away from the drain port 14, that is, the drain port 14 and the escape port 15 are arranged on opposite sides of the water inlet 13. Water flows from the water inlet 13 to the drain port 14, and the escape port 15 is away from the drain port 14, which can reduce the dirt in the tray 1 from leaking into the breeding pond from the escape port 15, reducing the impact on the sewage discharge efficiency. Further, the escape port 15 extends to the bottom plate 11, and the escape port 15 is immersed in the water body so that the live fish can escape.
[0052] The escape opening 15 is arranged on the retaining edge 12 to reduce the leakage of dirt. The escape opening 15 can also be arranged on the bottom plate 11 to make it easier for live fish to escape.
[0053] In some embodiments of the present application, the mesh size of the orifice plate 2 and the size of the escape port 15 can be set according to the size of the aquatic species actually cultured in the breeding pond, so that the fish can pass through the escape port 15 but cannot pass through the mesh of the orifice plate 2. Of course, the aquatic species cultured in the breeding pond are not limited to fish, and can also be shrimps, crabs, shellfish, etc.
[0054] In a specific embodiment of the present application, the perforated plate 2 can be fixedly connected to the tray 1 in a detachable manner, such as plugging, fastener connection, etc. According to the specific body shape of the fish or the body shape change of the fish during its growth period, the perforated plate 2 with different mesh sizes can be replaced.
[0055] The embodiment of the present application takes the application of an aquaculture sewage discharge device to an eel breeding pond as an example, and the orifice plate 2 and the escape port 15 are designed according to the body shape of the eel.
[0056] In some embodiments of the present application, the mesh aperture of the orifice plate 2 can be set between 4 mm and 6 mm, such as 4 mm, 5 mm or 6 mm, etc. The angle between the orifice plate 2 and the bottom plate 11 can be set between 5° and 30°, such as 10°, 15°, etc.
[0057] In some embodiments of the present application, the escape opening 15 can be configured as a strip-shaped long hole. The width of the escape opening 15 can be set between 7 mm and 10 mm, such as 8 mm, 9 mm, etc. The length of the escape opening 15 is at least set to 3 cm, such as 3 cm, 4 cm or 5 cm, etc.
