Description

Technical Field

[0001] This application relates to the field of aquaculture technology, and in particular to an ecological aquaculture box equipped with an air-lift sludge removal device. Background Technology

[0002] An ecological crab rearing box is a breeding device specifically designed for crabs to simulate a natural ecological environment. It is typically made of transparent glass or plastic, allowing for easy observation of the crabs' growth. The box is equipped with a circulating filtration system to maintain clean water and provide ample dissolved oxygen. The box contains aquatic plants, rocks, and other shelters to provide a safe molting area for the crabs. In addition, appropriate amounts of algae and microorganisms can be added to maintain ecological balance. By closely mimicking a natural environment, the crabs feel safer during the rearing process.

[0003] In ecological aquaculture, crabs require a strict control over water flow during molting. The flow needs to be weak and steady, as this provides sufficient dissolved oxygen to help the crabs molt successfully. However, the water flow generated during water circulation can negatively impact molting. During molting, crabs are relatively vulnerable, and excessively strong water flow can impact them, interfering with the molting process and even causing molting failure. Conversely, reducing the flow rate during water circulation may fail to meet the water quality requirements of crabs during molting. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the aforementioned technologies by providing an ecological aquaculture tank equipped with an air-lift sludge removal device, which simultaneously meets the requirements of crab molting for aquaculture water quality and circulating water flow rate.

[0005] Therefore, this utility model provides an ecological aquaculture box equipped with an air-lift sludge removal device. The ecological aquaculture box is equipped with a partition, which includes a first partition and a second partition. The first partition divides the aquaculture box into an aquaculture chamber and a water exchange chamber, and the second partition divides the water exchange chamber into an outlet chamber and an inlet chamber. The air-lift sludge removal device includes a first air-lift sludge removal device and a second air-lift sludge removal device. The first air-lift sludge removal device is installed in the aquaculture chamber, and its outlet extends into the outlet chamber. The second air-lift sludge removal device is installed in the inlet chamber, and its outlet extends into the aquaculture chamber.

[0006] Preferably, the ecological breeding box is equipped with an outlet pipe and an inlet pipe, with the outlet pipe connected to the outlet chamber and the inlet pipe connected to the inlet chamber.

[0007] Preferably, the first air-lift sludge removal device is equipped with a filter screen, an inlet pipe, and an outlet pipe. The filter screen is located at the upper end of the outlet pipe, and the lower end of the outlet pipe is connected to a side air-lift pipe. A sludge collection ring is provided at the bottom of the aquaculture chamber. The first air-lift sludge removal device and the second air-lift sludge removal device have the same structure. The inlet pipe and the outlet pipe are arranged adjacent to each other, and the inlet pipe and the outlet pipe are coaxial but have different diameters. The diameter of the inlet pipe is larger than the diameter of the outlet pipe, and there is a gap between the inlet pipe and the outlet pipe. The inlet pipe, the outlet pipe, and the side air-lift pipe form a sealed connecting pipe. An aeration pipe is connected to the inner side of the lower end of the side air-lift pipe. The aeration pipe is connected to the lower end of the pressure pipe, and the lower end of the pressure pipe is located inside the side air-lift pipe.

[0008] Preferably, the air stripping and slag removal device is also equipped with a sealing cover, which is detachably installed above the inlet pipe and the outlet pipe.

[0009] Preferably, the pressure pipe connection is equipped with a switch.

[0010] Preferably, the pressure gas pipe is connected to the main pressure gas pipe.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an ecological aquaculture tank equipped with an air-lift sludge removal device. The aquaculture water in the aquaculture chamber enters the outlet chamber through the first air-lift sludge removal device and is discharged from the outlet chamber through an external pipeline. Then, the purified aquaculture water enters the inlet chamber through another external pipeline and enters the aquaculture chamber through the second air-lift sludge removal device, thereby meeting the water quality requirements of crabs during molting. In aquaculture, the first and second air-lift sludge removal devices replace traditional water pumps and, combined with the buffering of the outlet and inlet chambers, reduce energy consumption and water flow impact. This avoids the stress caused to crabs during molting by the high flow rate of traditional water pumps and meets the requirement of a low flow rate for the circulating aquaculture water during crab molting.

[0015] To make the technical problems, technical solutions, and beneficial effects to be solved by this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of this application and are not intended to limit the scope of this application. Unless otherwise specified, the methods used in this utility model are conventional methods; the raw materials and apparatus used, unless otherwise specified, are conventional commercially available products.

[0016] Depend on Figure 1 , Figure 2 As shown, this utility model provides an ecological aquaculture box equipped with an air-lift sludge removal device. The ecological aquaculture box is equipped with a partition, which includes a first partition 1 and a second partition 2. The first partition divides the aquaculture box into an aquaculture chamber 3 and a water exchange chamber, and the second partition 2 divides the water exchange chamber into an outlet chamber 4 and an inlet chamber 5. The air-lift sludge removal device includes a first air-lift sludge removal device 6 and a second air-lift sludge removal device 7. The first air-lift sludge removal device 6 is installed in the aquaculture chamber 3, and its outlet extends into the outlet chamber 4. The second air-lift sludge removal device 7 is installed in the inlet chamber 5, and its outlet extends into the aquaculture chamber 3.

[0017] In operation, the aquaculture water in the aquaculture chamber 3 enters the outlet chamber 4 through the first air-lift cleaning device 6, and then is discharged from the outlet chamber 4 through an external pipeline, such as an external sewage treatment system, for purification. The purified aquaculture water enters the inlet chamber 5 through another external pipeline, and then enters the aquaculture chamber 3 through the second air-lift cleaning device 7, thus meeting the water quality requirements for crab molting. In aquaculture, the first air-lift cleaning device 6 and the second air-lift cleaning device 7 replace traditional water pumps, and, combined with the buffering of the outlet chamber 4 and the inlet chamber 5, reduce energy consumption and water flow impact. This avoids the stress caused to crabs during molting by the high flow rate of traditional water pumps, and meets the requirement of a low flow rate (0.1–0.3 m / s) for the circulating aquaculture water during crab molting.

[0018] In some embodiments, preferably, by Figure 2As shown, the ecological breeding box is connected to an outlet pipe 8 and an inlet pipe 9. The outlet pipe 8 is connected to the outlet chamber 4, and the water in the outlet chamber 4 flows out from the outlet pipe 8 for purification. The inlet pipe 9 is connected to the inlet chamber 5, and the purified water enters the inlet chamber 5 through the inlet pipe 9.

[0019] In some embodiments, preferably, by Figure 3 As shown, the first air-lift slag removal device 6 is equipped with a filter screen 10, an inlet pipe 11 and an outlet pipe 12. The filter screen 10 is located at the upper end of the outlet pipe 12, and the lower end of the outlet pipe 12 is connected to a side air-lift pipe 13. A slag collection ring 14 is provided at the bottom of the breeding chamber 3. The first air-lift slag removal device 6 and the second air-lift slag removal device 7 have the same structure.

[0020] The first air-lift sludge removal device 6 and the second air-lift sludge removal device 7 are structured as follows: the inlet pipe 11 and the outlet pipe 12 are arranged adjacent to each other, and the inlet pipe 11 and the outlet pipe 12 are coaxial but have different diameters. The diameter of the inlet pipe 11 is larger than the diameter of the outlet pipe 12, and there is a gap between the inlet pipe 11 and the outlet pipe 12. The inlet pipe 11, the outlet pipe 12, and the side air-lift pipe 13 form a sealed connecting pipe. An aeration pipe 16 is connected to the inner side of the lower end of the side air-lift pipe 13. The aeration pipe 16 is connected to the lower end of the pressure pipe 17, and the lower end of the pressure pipe 17 is also located inside the side air-lift pipe 13.

[0021] In operation, pressurized gas enters the aeration pipe 16 from the pressure pipe 17. Passing through the aeration pipe 16, the gas transforms into dense bubbles that enter the water in the side-mounted air-lift pipe 13, forming a water-gas mixture. Driven by the air pressure, the water-gas mixture rises along the side-mounted air-lift pipe 13. This upward movement of the water-gas mixture in the side-mounted air-lift pipe 13 causes the water in the connecting pipe to flow. External water enters from the sludge collection ring 14, carrying particulate sediment and feces within the ring upwards along the gap between the inlet pipe 11 and the outlet pipe 12. After being filtered by the filter screen 10, the water continues to flow in the outlet pipe 12 and the side-mounted air-lift pipe 13, finally exiting through the outlet of the elbow, achieving a very low flow rate.

[0022] In some embodiments, preferably, by Figure 3 As shown, the air stripping and slag removal device is also equipped with a sealing cover 15. The sealing cover 15 is detachably installed above the inlet pipe 11 and the outlet pipe 12. The sealing cover 15 is used for sealing. By opening the sealing cover 15, the filter screen 10 can be taken out for replacement.

[0023] In some embodiments, preferably, by Figure 3 As shown, a switch 18 is connected to the pressure pipe 17. The gas flow rate in the pressure pipe 17 is controlled by the switch 18. The switch 18 can also be opened or closed intermittently according to the actual situation of the aquaculture water to realize intermittent circulation of the aquaculture water and reduce energy consumption.

[0024] In some embodiments, preferably, by Figure 1 , Figure 3 As shown, the main pressure gas pipe 19 is connected to the pressure gas pipe 17, and the main pressure gas pipe 19 provides gas at a certain pressure to the pressure gas pipe 17.
