Description

Technical Field

[0001] This utility model relates to fish farming wastewater discharge, and in particular to a high-density fish farming wastewater discharge system, belonging to the field of fish pond wastewater discharge technology. Background Technology

[0002] In high-density fish farming scenarios, the amount of fish excrement, uneaten feed, and other impurities discharged into the water is much higher than in ordinary aquaculture models, which places more stringent requirements on the efficiency and stability of the sewage system.

[0003] Chinese Patent Publication No. CN219844619U discloses an automatic sewage discharge system for recirculating aquaculture fish ponds, belonging to the field of fish pond sewage discharge systems. The system includes a pond body and a base. The pond body is located above the base, which is filled with gravel. Multiple sleeves are integrally formed on the outer periphery of the pond body, and a support column is inserted into each sleeve, with the bottom of the support column penetrating through the sleeve. A sewage discharge mechanism is located at the bottom of the pond body, a water level control component is located on the back of the pond body, and a water circulation component is located on the front of the pond body. The water circulation component is connected to the water level control component. One end of the sewage discharge mechanism, the water level control component, and the water circulation component all penetrates into the interior of the pond body. This automatic sewage discharge system for recirculating aquaculture fish ponds can automatically discharge sewage at set times, eliminating manual operation and reducing the tediousness of manual sewage discharge. This allows for increased stocking density, increased production and income, and improved water quality, all of which are beneficial to farmed animals.

[0004] However, while existing sewage systems have achieved automation to some extent, they still have shortcomings. Some systems have poor impurity accumulation effects, and dead corners for impurity deposition are easily formed at the bottom of the pond, making it difficult to efficiently guide all impurities to the sewage discharge mechanism. At the same time, the separation of impurities from water is not thorough enough, resulting in a large amount of clean water being discharged with the sewage, which not only wastes water resources but also increases the cost of subsequent water treatment. Therefore, a high-density fish farming sewage discharge system is proposed. Summary of the Invention

[0005] In view of this, the present invention provides a high-density fish farming sewage discharge system to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0010] More preferably, a spiral conveying pipe is fixedly connected inside the sludge collection tank conveying pipe. The spiral conveying pipe is arranged along the inclined direction of the sludge collection tank conveying pipe, which can help guide impurities in the sludge collection tank conveying pipe to the spiral conveying pipe, so as to push them into the separation chamber conveying pipe through the spiral conveying pipe.

[0011] More preferably, the return water pipe is connected to a guide pipe, the end of the guide pipe away from the return water pipe passes through the pool body pipe and extends into it, and the openings of the return water pipe and the guide pipe inside the pool body pipe are set at an angle. The two work together to form a clockwise water flow in the pool body pipe, which helps impurities to gather towards the bottom center.

[0012] More preferably, the lower part of the tank conveying pipe and the lower part of the sludge collection tank conveying pipe are both funnel-shaped structures. The funnel-shaped structure of the tank conveying pipe facilitates the accumulation of impurities into the sludge discharge pipe, and the funnel-shaped structure of the sludge collection tank conveying pipe facilitates the accumulation of impurities into the screw conveying pipe and the screw conveying pipe.

[0013] More preferably, the filter screen conveying pipe is arranged around the top of the annular gap formed by the inner wall of the annular partition conveying pipe and the tank conveying pipe, and is used to filter the upper layer of clear water after sedimentation in the tank conveying pipe. The filtered clear water flows back to the tank conveying pipe through the return water conveying pipe.

[0030] like Figure 1-4 As shown, this utility model embodiment provides a high-density fish farming sewage system, including a base 10, a pond body 11, a sewage collection tank 20, and a tank body 12;

[0031] In one embodiment, the pool body 11 and the tank body 12 are mounted on the base 10. A sludge collection tank 20 is embedded in the bottom of the pool body 11. A conveying pipe 21 is connected to the bottom of the sludge collection tank 20. A circularly distributed through groove 22 is opened on the sludge collection tank 20. A separation chamber 26 is provided inside the tank body 12, and the opening of the separation chamber 26 faces upward. An annular partition 24 is fixedly connected inside the tank body 12. A support frame 25 is fixedly connected to the annular partition 24. The separation chamber 26 is fixedly connected to the annular partition 24 through the support frame 25. One end of the conveying pipe 21 passes through the tank body 12 and the separation chamber 26 and extends into the separation chamber 26. A return water pipe 13 is connected to one end of the tank body 12. A filter screen 27 is provided on the annular partition 24. A drain pipe 15 is connected to the bottom of the tank body 12. Valves 16 are provided on both the drain pipe 15 and the return water pipe 13.

[0032] The pool body 11 and tank body 12 are integrated on the base 10, which facilitates overall installation, movement and fixation, and improves the structural stability of the system. The cooperation between the sludge collection tank 20 and the conveying pipe 21 can promptly transport impurities from the bottom of the pool body 11 to the separation chamber 26 of the tank body 12, avoiding excessive accumulation of impurities in the pool body 11. The separation chamber 26 provides space for the initial separation of impurities and water. The annular baffle 24 and the support frame 25 can stably support the separation chamber 26 to ensure the smooth progress of the separation process. The return water pipe 13 can realize the return of treated clean water, improving the water resource utilization rate. The filter screen 27 can filter and purify the clean water to ensure the water quality returned to the pool body 11. The sewage pipe 15 is used to discharge the separated impurities, and the valve 16 can flexibly control the sewage discharge and return water process to meet the sewage discharge needs of different breeding stages.

[0033] In one embodiment, the bottom of the pool body 11 is inclined towards the center so that impurities can gather towards the collection tank 20. The inclined bottom of the pool body 11 uses gravity to guide fish excrement, uneaten food and other impurities to slide naturally towards the collection tank 20 in the center, reducing the residual area of ​​impurities at the bottom of the pool body 11, improving the accumulation efficiency of impurities, laying the foundation for the subsequent sewage discharge process, and ensuring more thorough sewage discharge.

[0034] The number of channels 22 on the sludge collection tank 20 is four to eight, and they are evenly distributed along the circumference of the sludge collection tank 20. They are used to guide water and impurities from the bottom of the pool 11 into the sludge collection tank 20. The four to eight evenly distributed channels 22 can collect water and impurities from the bottom of the pool 11 from multiple directions at the same time, expanding the sludge collection range and increasing the speed at which impurities enter the sludge collection tank 20. The circumferential distribution design allows impurities from all directions to enter the sludge collection tank 20 evenly, avoiding local accumulation and blockage of impurities and ensuring the smoothness of the sludge collection process.

[0035] A spiral rod 23 is fixedly connected inside the sludge collection tank 20. The spiral rod 23 is set along the inclined direction of the sludge collection tank 20, which can help guide the impurities in the sludge collection tank 20 to the spiral conveying pipe 21, so as to push them into the separation chamber 26 through the spiral conveying pipe 21. The spiral rod 23 is set along the inclined direction of the sludge collection tank 20, and can generate a pushing force on the impurities in the sludge collection tank 20 by its own spiral structure, which helps the impurities move towards the conveying pipe 21, prevents the impurities from being stuck or blocked in the sludge collection tank 20, speeds up the conveying speed of the impurities, ensures that the impurities can enter the separation chamber 26 efficiently, and improves the overall sewage discharge efficiency.

[0036] In one embodiment, a guide pipe 14 is connected to the return water pipe 13. The end of the guide pipe 14 away from the return water pipe 13 passes through the pool body 11 and extends into it. The openings of the return water pipe 13 and the guide pipe 14 inside the pool body 11 are set at an angle. The two work together to form a clockwise water flow in the pool body 11, which helps impurities to gather towards the bottom center. The angled opening design formed by the return water pipe 13 and the guide pipe 14 can form a clockwise water flow in the pool body 11. The centripetal force generated by the water flow can drive floating or suspended impurities to move towards the bottom center of the pool body 11. Combined with the gravity guidance effect of the inclined bottom of the pool body 11, the aggregation effect of impurities is further enhanced, allowing more impurities to enter the sludge collection tank 20 and improving the thoroughness of sewage discharge.

[0037] Both the lower part of the tank body 12 and the lower part of the sludge collection tank 20 have funnel-shaped structures. The funnel-shaped structure of the tank body 12 facilitates the accumulation of impurities towards the discharge pipe 15, while the funnel-shaped structure of the sludge collection tank 20 facilitates the accumulation of impurities towards the screw rod 23 and the screw conveying pipe 21. The funnel-shaped structure, with its conical shape, allows impurities in the tank body 12 to converge towards the discharge pipe 15 at the bottom under the action of gravity and water flow, increasing the discharge speed of impurities and reducing the residue of impurities in the tank body 12. The funnel-shaped structure of the sludge collection tank 20 can guide impurities to accumulate towards the screw rod 23 and the conveying pipe 21. With the pushing action of the screw rod 23, it accelerates the efficiency of impurities entering the conveying pipe 21, avoids impurities clogging in the sludge collection tank 20, and ensures the stable operation of the sewage discharge system.

[0038] A filter screen 27 is arranged around the top of the annular gap formed by the annular partition 24 and the inner wall of the tank 12. It is used to filter the upper layer of clear water after sedimentation in the tank 12. The filtered clear water flows back to the pool 11 through the return water pipe 13. The filter screen 27 at the top of the annular gap can effectively filter the fine impurities and suspended particles in the upper layer of clear water after sedimentation in the tank 12, improve the cleanliness of the returned clear water, and prevent impurities from polluting the water quality as they flow back to the pool 11. The surrounding filter screen 27 increases the filtration area and improves the filtration efficiency, ensuring that the clear water can flow back to the pool 11 quickly and cleanly, realizing the recycling of water resources and reducing the cost of aquaculture water.

[0039] When this utility model is in operation: fish excrement, uneaten feed and other impurities generated during the aquaculture process are guided by gravity of the inclined structure at the bottom of the pool 11 to gather in the central sludge collection tank 20; at the same time, the clockwise water flow formed by the return pipe 13 and the guide pipe 14 inside the pool 11 generates centripetal force, which drives the floating or suspended impurities to move together towards the sludge collection tank 20.

[0040] Impurities enter the collection tank 20 through the circumferentially distributed channels 22 along with the water flow. The funnel-shaped structure below the collection tank 20 guides the impurities to gather towards the spiral rod 23 and the conveying pipe 21. The spiral rod 23 pushes the impurities to the conveying pipe 21, and then transports them to the separation chamber 26 inside the tank body 12.

[0041] Impurities entering the separation chamber 26 are initially separated from the water. The impurities and water overflow from the opening of the separation chamber 26 into the tank 12. The impurities settle downwards under the action of gravity and fall into the bottom of the tank 12 through the separation chamber 26. The funnel-shaped structure below the tank 12 causes the impurities to gather towards the drain pipe 15. The impurities can be discharged by opening the valve 16 on the drain pipe 15.

[0042] The water overflows upwards from the separation chamber 26 and enters the annular gap formed by the annular baffle 24 and the inner wall of the tank 12. After being filtered by the filter screen 27 at the top of the annular baffle 24, the upper layer of clean water flows back to the tank 11 through the return water pipe 13. The valve 16 on the return water pipe 13 can control the return water flow rate, realizing the recycling of water resources. The entire process, through the coordinated action of various components, efficiently completes the collection, transportation, separation, and return of impurities and clean water, ensuring the stability of water quality in the high-density aquaculture pond.

[0043] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
