Description

Technical Field

[0001] This utility model relates to the field of aquaculture technology, specifically to an aquaculture pond that facilitates the cleaning of silt. Background Technology

[0002] For example, patent document CN 220441637 U discloses a sturgeon breeding pond with easily cleanable bottom sludge. First, a sliding fishing net guides the fish upwards, and then a silicone strip is fixed in the pond to prevent a sludge scraper from contaminating the water above when scraping the bottom sludge. While this method can clean the sludge, the driving mechanism of the sliding fishing net and silicone strip is only suitable for regularly shaped square breeding ponds. It cannot be implemented for various irregularly shaped breeding ponds in practical applications, hindering its widespread adoption. Utility Model Content

[0003] To address the problems and shortcomings of existing technologies, this utility model provides a convenient method for cleaning sludge in aquaculture ponds. The aim is to make it applicable to aquaculture ponds of various shapes, thereby improving the ease of sludge cleaning and expanding its application scope.

[0004] The technical solution of this utility model is as follows:

[0005] An aquaculture pond that facilitates sludge removal includes a water storage chamber separated by two partition walls with a middle interval, and two aquaculture chambers distributed on both sides of the water storage chamber.

[0006] The bottom of the partition wall is fixed with a connecting pipe that runs through the water storage chamber. The connecting pipe is connected to the breeding chambers on both sides, and there are doors at both ends that can be opened automatically.

[0007] A water pump is installed inside the water storage chamber enclosed by a partition wall. The water inlet of the pump is connected to the drain pipes of the two breeding chambers on both sides through pipes, and the water outlet of the pump is connected to the water inlet pipes of the two breeding chambers on both sides through pipes. The water pump is located in a separate equipment room inside the water storage chamber, which is isolated from the water storage area of ​​the water storage chamber.

[0008] The bottom of the aquaculture pond is equipped with a sludge tank, and an automatically rotating impeller is rotatably connected to the side wall. The bottom of the sludge tank is connected to the inlet of the mud pump, and the outlet of the mud pump is connected to the sewage pipe.

[0009] The practical application of this utility model is as follows:

[0010] When cleaning the sludge in the aquaculture chamber, first open the doors on both sides of the connecting pipe, and start the motor in one aquaculture chamber to rotate the shaft, which in turn drives the impeller to rotate, stirring the water in that chamber. This disturbs the fish and causes them to swim through the connecting pipe to the other aquaculture chamber. Then, close the doors at both ends of the connecting pipe to disconnect the two aquaculture chambers. Next, start the water pump and connect the drain pipe of the aquaculture chamber without fish to the pump inlet using the control valve to pump water into the storage chamber for temporary storage. Then, start the mud pump to remove the sludge from the dry side for waste material production. After the sludge has been removed, connect the pump outlet to the inlet pipe of the dry aquaculture chamber using the control valve to fill the chamber with water. Once the water level reaches the appropriate level, open the doors at both ends of the connecting pipe to connect the two aquaculture chambers. Then, start the motor on the side with fish to rotate the impeller, driving the fish to the other aquaculture chamber. Repeat the above steps to clean the sludge in the sludge tank on the other side. After cleaning, water is pumped into the breeding chambers, and the door of the connecting pipe is opened to allow the fish to move freely between the two breeding chambers, thus distributing them evenly in the two breeding chambers.

[0011] According to a specific embodiment, the impeller is rotatably connected to the side wall of the aquaculture chamber via a rotating shaft. One end of the shaft extends perpendicularly into the aquaculture chamber from the side wall, while the other end extends out of the side wall and is connected to a motor. The rotational speed of the shaft is adjustable, allowing the impeller to operate at a low speed when sludge removal is not required, thereby increasing the oxygen content of the water in the aquaculture chamber.

[0012] Furthermore, to increase the agitation range, multiple impellers are spaced apart along the axial direction of the shaft. Even further, multiple shafts with impellers are arranged along the four sides of the culture chamber.

[0013] To allow the fish to smoothly enter the aquaculture chamber on the other side from the connecting pipe, the impeller is positioned above the connecting pipe in the vertical direction, and near the middle of the aquaculture chamber's cross-section.

[0014] The water inlet pipe is located at the top of the partition wall, near the top surface of the partition wall, and the drain pipe is located at the bottom of the partition wall, near the bottom of the breeding chamber and above the sludge pool.

[0015] To facilitate the cleaning of the sludge ponds on both sides, a mud pump is installed between the two sludge ponds.

[0016] The beneficial effects of this utility model are:

[0017] This method not only solves the problem of low efficiency in existing technologies that require manually catching fish and then flushing the aquaculture pond, but also effectively prevents sludge from floating up and polluting the clean water above during the cleaning process. Furthermore, it can be used in aquaculture ponds of various irregular shapes to improve the ease of sludge removal and expand its application scope. Attached Figure Description

[0022] The technical means adopted to achieve the intended purpose of this utility model will be further described below with reference to the accompanying drawings of the embodiments of this utility model.

[0023] Example

[0024] See Figures 1-3 As shown, an aquaculture pond that facilitates sludge removal includes a water storage chamber 3 separated by two partition walls 2 with a middle interval, and two aquaculture chambers 1 distributed on both sides of the water storage chamber 3.

[0025] The bottom of the partition wall 2 is fixed with a connecting pipe 4 that runs through the water storage chamber 3. The connecting pipe 4 is connected to the breeding chambers 1 on both sides, and both ends are equipped with doors that can be opened automatically.

[0026] A water pump 7 is installed inside the water storage chamber 3 enclosed by the partition wall 2. The water inlet of the water pump 7 is connected to the drain pipes 9 of the two breeding chambers 1 on both sides through pipes, and the water outlet of the water pump 7 is connected to the water inlet pipes 8 of the two breeding chambers 1 on both sides through pipes. The water pump 7 is located in a separate equipment room inside the water storage chamber 3, which is separated from the water storage area of ​​the water storage chamber 3.

[0027] The bottom of the aquaculture pond is equipped with a sludge tank 5, and an automatically rotating impeller 10 is rotatably connected to the side wall. The bottom of the sludge tank 5 is connected to the inlet of the mud pump 6, and the outlet of the mud pump 6 is connected to the sewage pipe.

[0028] The practical application of this utility model is as follows:

[0029] When it is necessary to clean the sludge in the aquaculture chamber 1, first open the doors on both sides of the connecting pipe 4, and start the motor in one aquaculture chamber 1 to rotate the shaft 11, which in turn drives the impeller 10 to rotate, stirring the water in that aquaculture chamber 1. This disturbs the fish in that aquaculture chamber 1, causing them to swim to the other aquaculture chamber 1 through the connecting pipe 4. Then close the doors at both ends of the connecting pipe 4 to disconnect the two aquaculture chambers 1. Next, start the water pump 7, and connect the drain pipe 9 of the aquaculture chamber 1 without fish to the inlet of the water pump 7 through the control valve, pumping water into the storage chamber 3 for temporary storage. Afterward, start the mud pump 6 to pump out the sludge from the side without water for waste material production.

[0030] After the sludge is pumped out, the outlet of the water pump 7 is connected to the inlet pipe 8 of the aquaculture chamber 1 on the side without water by controlling the valve, and water is filled into the aquaculture chamber 1. When the water reaches the appropriate water level, the doors at both ends of the connecting pipe 4 are opened to connect the two aquaculture chambers 1. Then the motor on the side with fish is started to make the impeller 10 rotate, driving the fish to the other aquaculture chamber 1. The above steps are repeated to clean the sludge in the sludge pool 5 on the other side.

[0031] After cleaning, water is pumped into the breeding chamber 1 through the water pump 7, and the door of the connecting pipe 4 is opened to allow the fish to move freely between the two breeding chambers 1, thus dispersing them evenly in the two breeding chambers 1.

[0032] According to a specific embodiment, the impeller 10 is rotatably connected to the side wall of the aquaculture chamber 1 via a rotating shaft 11. One end of the rotating shaft 11 extends perpendicularly into the side wall of the aquaculture chamber 1, while the other end extends out of the side wall of the aquaculture chamber 1 and is connected to a motor. The rotational speed of the rotating shaft 11 is adjustable, allowing the impeller 10 to operate at a low speed when sludge removal is not required, thereby increasing the oxygen content of the water in the aquaculture chamber 1.

[0033] Furthermore, to increase the agitation range, multiple impellers 10 are spaced apart along the axial direction of the shaft 11. Even further, multiple shafts 11 with impellers 10 are arranged along the four sides of the culture chamber 1.

[0034] To allow the fish to smoothly enter the aquaculture chamber 1 on the other side from the connecting pipe 4, the impeller 10 is positioned above the connecting pipe 4 in the vertical direction, and is located near the middle of the cross-section of the aquaculture chamber 1.

[0035] The water inlet pipe 8 is located at the top of the partition wall 2, near the top surface of the partition wall 2, and the drain pipe 9 is located at the bottom of the partition wall 2, near the bottom surface of the breeding chamber 1, near the sludge pool 5.

[0036] To facilitate the cleaning of the sludge pools 5 on both sides, the mud pump 6 is installed between the two sludge pools 5.
