Description

Technical Field

[0001] This utility model relates to the field of fish fry rearing ponds, and in particular to a fish fry rearing pond with waste discharge function. Background Technology

[0002] Fish excrement is produced during the fry rearing process, and uneaten feed is generated from the fry. Fish excrement and uneaten feed constitute the main waste in the rearing pond. This waste is rich in nutrients, and its long-term accumulation leads to eutrophication, affecting fry growth and water quality. Therefore, regular pond cleaning and maintenance are necessary to remove sediment from the bottom and maintain the environment. However, pond cleaning requires transferring all cultured organisms and draining the water, consuming a large amount of water each time. Furthermore, the pond bottom needs to be left to dry for a long time, which can be affected by weather conditions, extending the maintenance period and disrupting the rearing plan.

Solid waste in the pond is discharged to a solid waste discharge container through a solid-liquid input pipe. Then, the pump in the clear liquid discharge pipe outputs the clear liquid from the upper layer of the solid waste discharge container to a clear liquid collection container. The clear liquid collection container outputs the clear liquid back to the pond through a return pipe.

[0018] like Figure 1-1 A fish fry rearing pond with waste discharge function includes: pond body 1, solid waste discharge container 2, clear liquid collection container 3, and waste discharge component 4; The waste discharge assembly 4 includes: a solid-liquid input pipe 41, a clear liquid discharge pipe 42, a pump body 43, and a return pipe 44; The input end of the solid-liquid input pipe 41 is connected to the pool body 1, and the connection position is close to the bottom wall of the pool body 1; the output end of the solid-liquid input pipe 41 is connected to the solid waste discharge container 2; the input end of the clear liquid discharge pipe 42 extends into the solid waste discharge container 2 and is located above the bottom wall of the solid waste discharge container 2; the output end of the clear liquid discharge pipe 42 is connected to the clear liquid collection container 3; the pump body 43 is installed on the clear liquid discharge pipe 42; the input end of the return pipe 44 is connected to the clear liquid collection container 3, and the output end of the return pipe 44 is connected to the pool body 1.

[0019] This solution provides a fish fry rearing pond with a waste discharge function. Solid waste in the pond 1 is discharged to the solid waste discharge container 2 through the solid-liquid input pipe 41. Then, the pump body 43 of the clear liquid discharge pipe 42 outputs the clear liquid on the upper layer of the solid waste discharge container 2 to the clear liquid collection container 3. The clear liquid collection container 3 outputs the clear liquid back to the pond 1 through the return pipe 44. This realizes the concentration of solid waste in the solid waste discharge container 2, thereby removing the waste generated during the fish fry rearing period in the pond 1, improving the cleanliness of the pond 1, and solving the problem of high water consumption caused by the need to change the water every time the existing fish fry rearing pond discharges waste.

[0020] Specifically, pond 1 is the main location for raising fish fry. During the raising process, the fish fry will excrete fish feces, and uneaten feed will be generated. Fish feces and uneaten feed are the main wastes, which are rich in nutrients. Over time, their accumulation leads to eutrophication of the water body, affecting the growth of fish fry and water quality safety. The input end of the solid-liquid input pipe 41 is connected to the bottom wall of pond 1. Large-particle waste settles to the bottom of pond 1 after prolonged water absorption. Pond 1 can actively (e.g., by a pump) or passively (e.g., by pressure difference) discharge water from the bottom to the solid-liquid input pipe 41 based on hydraulic pressure difference. The solid-liquid input pipe 41 outputs water containing waste to the solid waste discharge container 2, transferring the waste to the solid waste discharge container 2. After being transferred to the solid waste discharge container 2, the waste will settle to the bottom wall of the solid waste discharge container 2 and exit after a certain period of time. Currently, wastewater and water are separated into layers, with the clear liquid in the water layer above the solid waste. The inlet of the clear liquid discharge pipe 42 is located above the bottom wall of the solid waste discharge container 2, primarily within the clear liquid layer. The outlet of the clear liquid discharge pipe 42 is located in the clear liquid collection container 3. When the pump 43 of the clear liquid discharge pipe 42 is activated, it outputs the clear liquid to the clear liquid collection container 3, resulting in most of the clear liquid being discharged there. The clear liquid in the clear liquid collection container 3 then flows back to the tank 1 via the return pipe 44, thus reusing the clear liquid. In this way, after flowing through the solid-liquid inlet pipe 41, the clear liquid discharge pipe 42, and the return pipe 44, the wastewater in the tank 1 is concentrated in the solid waste discharge container 2, and the clear liquid is returned to the clear liquid collection container 3. This wastewater treatment method is convenient and does not lead to a large water consumption problem.

[0021] The waste collected by solid waste container 2 can be post-treated in a known manner, such as regular manual cleaning and recycling, or a purification device can be installed to further remove some of the waste.

[0022] Optimally, the outer edge of the bottom wall of the pool body 1 gradually slopes down towards the center; a drain outlet 11 is provided at the center of the bottom wall of the pool body 1; The input end of the solid-liquid input pipe 41 is connected to the drain outlet 11.

[0023] In this design, the bottom wall of the pool 1 is preferably designed so that the outer edge is higher than the middle. The outer edge of the bottom wall of the pool 1 gradually descends towards the center, thus forming an inclined bottom surface 12. The sewage outlet 11 is located at the lowest point of the pool 1. When the waste is distributed in the area outside the center, the waste will move towards the sewage outlet 11 in the center under the action of gravity and water flow, thereby concentrating the waste at the sewage outlet 11 and discharging it.

[0024] Optimally, it also includes: a ring pipe 5 and a water supply pipe 6; The annular pipe 5 is disposed on the outer edge of the bottom wall of the pool body 1. The inner ring of the annular pipe 5 is surrounded by water outlet holes 51, which face the sewage outlet 11. The output end of the water supply pipe 6 is connected to the annular pipe 5. The input end of the water supply pipe 6 is used to input aquaculture water.

[0025] The water supply pipe 6 is used to supply aquaculture water to the ring pipe 5, thereby supplementing the aquaculture water supply to the pond 1 through the ring pipe 5. Simultaneously, the ring pipe 5 has multiple annularly distributed water outlets 51. After receiving the aquaculture water, the ring pipe 5 discharges the aquaculture water through the water outlets 51. Since the water outlets 51 face the sewage outlet 11, when multiple water outlets 51 discharge aquaculture water, waste from the bottom wall of the pond 1 can be discharged towards the sewage outlet 11. Combined with the shape of the bottom wall of the pond 1, the waste can be further discharged towards the sewage outlet 11, preventing waste from remaining on the bottom wall of the pond 1. Thus, the ring pipe 5 serves both to supplement aquaculture water and to discharge waste to the sewage outlet 11.

[0026] Optimally, it also includes: a sewage discharge device 7; The sewage discharge device 7 includes: a sewage discharge net cylinder 71 and a water-blocking cylinder 72; The lower end of the sewage discharge net cylinder 71 is installed at the sewage discharge port 11, and the sewage discharge net cylinder 71 is provided with mesh holes; the water-blocking cylinder 72 is sleeved on the upper end of the sewage discharge net cylinder 71.

[0027] The waste discharge net cylinder 71 has multiple mesh openings to discharge waste. By designing the mesh opening diameter to be between the size of the fish fry and the size of the waste, waste can be discharged selectively. In particular, the pond body 1 in this design is concave in the middle, allowing waste to collect in the center of the pond body 1. Heavier waste sinks and flows through the mesh openings into the waste discharge outlet 11, from where it flows out to the solid waste container 2, achieving automatic waste discharge. Simultaneously, a water-blocking cylinder 72 is fitted onto the upper end of the waste discharge net cylinder 71, covering the mesh openings to control the water level and prevent excessive water from flowing out through the mesh.

[0028] Optimally, the height of the clear liquid collection container 3 is greater than the height of the pool body 1, and the return pipe 44 outputs the clear liquid from the clear liquid collection container 3 to the pool body 1 through a pressure difference.

[0029] The height of the clear liquid collection container 3 is greater than the height of the pool body 1, for example, it can be 1, 1.5, or 2 times greater; the liquid level of the clear liquid collection container 3 can be greater than the liquid level of the pool body 1; when the liquid level of the clear liquid collection container 3 can be greater than the liquid level of the pool body 1, the liquid pressure of the clear liquid collection container 3 is greater than the pressure of the pool body 1. The clear liquid collection container 3 can output the clear liquid to the pool body 1 through the return pipe 44 through the pressure difference, thereby saving the pump structure required for the transmission between the pool body 1 and the clear liquid collection container 3, and simplifying the clear liquid transportation structure.

[0030] Optimally, it also includes: a liquid level sensing device 8; The liquid level sensor 8 is disposed on the inner wall of the clear liquid collection container 3; the liquid level sensor 8 is communicatively connected to the pump body 43.

[0031] The liquid level sensor 8 can be used to sense the liquid level in the clear liquid collection container 3 and can control the pump body 43 to start or stop according to the liquid level. The number of liquid level sensors 8 can be selected as needed. A single sensor or at least two sensors can be set to control the pump body 43 to start or stop at different liquid levels. For example, in one embodiment, a single liquid level sensor 8 is set in the middle of the clear liquid collection container 3. When the liquid level drops to the middle, the liquid level sensor 8 controls the pump body 43 to start and draw clear liquid from the solid waste discharge container 2 through the clear liquid discharge pipe 42 to replenish the clear liquid. For example, in one embodiment, two liquid level sensors 8 are set at the upper and lower positions of the clear liquid collection container 3, respectively. When the liquid level drops to the lower position, the lower liquid level sensor 8 controls the pump body 43 to start and draw clear liquid from the solid waste discharge container 2 through the clear liquid discharge pipe 42 until the clear liquid rises to the upper liquid level sensor 8, at which point the upper liquid level sensor 8 controls the pump body 43 to stop. Thus, the liquid level sensing device 8 can automatically replenish the clean liquid by controlling the pump body 43 to start or stop.

[0032] The communication connection method here refers to the communication established between connected devices through signal transmission and interaction, which can be divided into wired connection and wireless connection; wired connection is such as conventional data cable connection; wireless connection is such as conventional WiFi, Bluetooth, infrared, NFC, etc.

[0033] Optimally, the return pipe 44 is provided with a horizontal return section 441 and a vertical return section 442; One horizontal end of the horizontal reflux section 441 is connected between the middle and bottom of the clear liquid collection container 3, and the other horizontal end of the horizontal reflux section 441 is connected to the lower end of the vertical reflux section 442. The upper end of the vertical reflux section 442 is located above the opening of the pool body 1.

[0034] The return pipe 44 has a horizontally extending horizontal return section 441 and a vertically extending vertical return section 442. When the liquid level in the clear liquid collection container 3 is between the middle and the bottom, and the liquid level is higher than the upper end of the vertical return section 442, the clear liquid is horizontally output through the horizontal return section 441 to the vertical return section 442 under pressure. The clear liquid is then output from the upper end of the vertical return section 442 from bottom to top to the opening of the pool body 1. Since the liquid level of the clear liquid rises from low to high in the vertical return section 442, the flow rate of the clear liquid will not be too fast when it is output. At the same time, since the return pipe 44 is not directly connected to the inner wall of the pool body 1, the water in the pool body 1 will not flow back into the clear liquid collection container 3 through the return pipe 44 and contaminate the clear liquid.

[0035] Alternatively, the waste discharge assembly 4 may further include: a valve body 45; The valve body 45 is installed on the solid-liquid input pipe 41.

[0036] The valve body 45 is installed on the solid-liquid inlet pipe 41, mainly to control the passage of waste and water from the pool 1 through the solid-liquid inlet pipe 41; when the valve body 45 is opened, the pool 1 is connected to the solid waste discharge container 2; when the valve body 45 is closed, the pool 1 and the solid waste discharge container 2 are separated.

[0037] Optimally, it also includes: filter screen 9; The filter screen 9 is disposed in the solid waste discharge container 2; The output end of the solid-liquid input pipe 41 is located below the filter screen 9; the input end of the clear liquid discharge pipe 42 is located above the filter screen 9.

[0038] Since the output end of the solid-liquid input pipe 41 is located below the filter screen 9, the aquaculture water containing wastewater output from the solid-liquid input pipe 41 rises from low to high, and its water level rises past the filter screen 9. The filter screen 9 filters the aquaculture water, so that the wastewater is located below the filter screen 9 and the clean water is located above the filter screen 9. The input end of the clean liquid discharge pipe 42 is located above the filter screen 9, and it can be pumped into the clean liquid collection container 3 through the pump body 43. In this way, the filter screen 9 can further improve the filtration degree of the clean water. More preferably, when the pump body 43 is started, if the output end of the solid-liquid input pipe 41 is located in the wastewater part of the layer and the input end of the clean liquid discharge pipe 42 is located in the clean liquid layer, then when the pump body 43 outputs the clean liquid to the clean liquid collection container 3, it can also pump the aquaculture water of the tank 1 into the solid waste discharge container 2 through the solid-liquid input pipe 41. The filter screen 9 can separate the wastewater part pumped from the tank 1 between the layers.
