[0002] Aquaculture refers to the production activities of breeding, cultivating, raising, and harvesting aquatic economic plants and animals under artificial control. It is an important component of modern fisheries and a crucial means of ensuring the supply of aquatic products and promoting the sustainable development of fisheries. Aquaculture is an important agricultural production activity that not only provides people with abundant aquatic products but also plays a vital role in economic development and ecological protection. Aquaculture waste collection and discharge devices are used to collect and discharge waste and excess water generated during the aquaculture process. They are very important in modern aquaculture because an effective waste collection and discharge system can maintain the cleanliness of the aquaculture water, reduce the accumulation of pollutants, lower the risk of disease, and improve the efficiency of water resource utilization.

[0003] Meanwhile, existing sewage collection and discharge devices are usually insufficient in terms of water flow power, which makes it impossible to effectively push pollutants in the aquaculture ponds to the collection tank. This results in incomplete sewage collection and untimely discharge, causing fish and shrimp feces to accumulate in the aquaculture ponds and decompose anaerobically, leading to the deterioration of the aquaculture water and affecting the healthy growth of fish and shrimp. Summary of the Invention

[0004] In order to overcome the problem that existing sewage collection and discharge devices usually have insufficient water flow power, which makes it impossible to effectively push pollutants in the aquaculture pond to the sewage collection tank, resulting in incomplete sewage collection and untimely sewage discharge, causing fish and shrimp feces to accumulate in the aquaculture pond and decompose anaerobically, leading to the deterioration of the aquaculture water and affecting the healthy growth of fish and shrimp, this utility model provides an aquaculture sewage collection and discharge device.

[0005] The technical solution is as follows: A sewage collection and discharge device for aquaculture includes an aquaculture pond and a cylindrical barrel; it also includes a conical groove with a conical groove in the center of the aquaculture pond, and a cylindrical barrel installed on the inner side of the conical groove; it also includes a sewage discharge pipe, a diversion pipe, an aeration pipe, a sealing plate, a magnetic block, an overflow pipe and a filter screen. Multiple sets of aeration pipes that push the aquaculture water to rotate slowly clockwise are installed circumferentially on the inner wall of the aquaculture pond.

[0021] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-4 As shown, an aquaculture waste collection and discharge device includes an aquaculture pond 1 and a cylindrical barrel 2; it also includes a conical groove with a central opening in the center of the aquaculture pond 1, with the cylindrical barrel 2 installed inside the conical groove; it further includes a waste discharge pipe 3, a diversion pipe 4, an aeration pipe 6, a sealing plate 8, a magnetic block 9, an overflow pipe 12, and a filter screen 14. Multiple sets of aeration pipes 6 are circumferentially installed on the inner wall of the aquaculture pond 1 to slowly rotate the aquaculture water clockwise. One end of each aeration pipe 6 is connected to an aerator via a connecting cable 7 on the outer wall of the aquaculture pond 1. An auxiliary aeration device is installed at the bottom of the cylindrical barrel 2. A conical base for collecting and settling solids slowly; a filter plate is installed at the upper end of the cylindrical barrel 2, and several sets of limiting bolts 15 are provided around the upper end of the filter plate, which is fastened to the cylindrical barrel 2; a threaded hole for accommodating several sets of limiting bolts 15 is opened at the upper end of the cylindrical barrel 2, and the filter plate is threadedly fixed to the cylindrical barrel 2 by several sets of limiting bolts 15; a sewage pipe 3 is connected to the lower end of the cylindrical barrel 2, and the sewage pipe 3 extends through the breeding pond 1 to the outer end. Two diversion pipes 4 are connected and fixed to the outer wall of the sewage pipe 3, and the two diversion pipes 4 are connected and fixed to the breeding pond 1.

[0023] like Figures 2-4 As shown, two sets of sealing plates 8 are installed inside the conical groove, and magnetic blocks 9 are fixed inside the two sets of sealing plates 8. Iron strips are installed circumferentially on the inner walls of the two diversion pipes 4. The two sets of sealing plates 8 are magnetically fastened to the diversion pipes 4 through the magnetic blocks 9. A connecting rope 10 is fixed to the outer end of the two sets of sealing plates 8, and a weight block 11 is fixed to the end of the connecting rope 10 away from the sealing plate 8. An overflow pipe 12 is fixed to the outer end of the sewage pipe 3. The overflow pipe 12 is connected to the sewage pipe 3. The overflow pipe 12 extends through the breeding pond 1 into the interior. A funnel 13 is fixed to the end of the overflow pipe 12 away from the sewage pipe 3. A docking plate 5 is welded to the end of the sewage pipe 3 away from the cylindrical barrel 2. Multiple sets of connecting holes are opened circumferentially inside the docking plate 5.

[0024] During the aquaculture process using aquaculture pond 1, the connecting cable 7 is used to connect to the aerator. Starting the aerator causes multiple sets of aeration pipes 6 on the inner wall of aquaculture pond 1 to slowly rotate the water body clockwise, bringing larger solids to the center. Once the solids are in the center, the water surface in the central cylindrical tank 2 of aquaculture pond 1 becomes relatively calm. Under gravity, the solids slowly settle into the conical base of the cylindrical tank 2. A removable filter screen 14 is installed at the top of the cylindrical tank 2 to prevent fish and shrimp from entering. This screen is gradually replaced according to the growth of the fish and shrimp. After most of the solids are collected in the conical trough, the water pump is connected to the sewage pipe 3 using the docking plate 5. When the sewage pipe 3 is connected and ready to discharge sewage, the feeder manually grabs the connecting rope 10 and pulls the sealing plate 8 to open the diversion pipe 4, so as to discharge the solid impurities collected in the conical trough. When the sewage pipe 3 is opened, the solid impurities collected in the barrel 2 and the impurities in the conical trough are discharged together. Sewage is discharged regularly according to the feed feeding, and the solids such as feces and feed residue collected in the sludge collector are discharged from the breeding pond 1 in a short time.

[0025] Furthermore, it is considered that during the discharge of solid impurities inside the conical trough, the overflow pipe 12 can be connected to the funnel 13 to collect the impurities on the liquid surface and discharge them together, thereby reducing the residue of solids inside the aquaculture pond 1. After the solid impurities are discharged, the connecting rope 10 is loosened and the magnetic block 9 is magnetically fastened to the iron sheet inside the diversion pipe 4 to seal it, preventing the water inside the aquaculture pond 1 from flowing out. It also guides the collection and discharge of impurities in a timely manner, which can prevent the accumulation of fish and shrimp feces in the aquaculture pond 1, avoid the deterioration of the aquaculture water, provide a better living environment for fish and shrimp, reduce the amount of water replenishment and replacement, and ensure the healthy growth of fish and shrimp.
