Description

Technical Field

[0001] This utility model relates to the field of marine aquaculture, specifically a water circulation device for sea urchin farming. Background Technology

[0002] my country's aquaculture facility treatment technology is at a low level, with rudimentary equipment. Most facilities only involve simple sedimentation, filtration, flotation, and disinfection, lacking efficient biochemical treatment measures and recirculating aquaculture systems. Furthermore, there is a lack of detoxification measures for pesticides, herbicides, and other small-molecule toxic compounds in the raw aquaculture water. This is a significant factor restricting the sustainable development of my country's aquaculture industry.

[0003] A search revealed Chinese Patent Publication No. CN215774984U, which discloses a water circulation device for aquaculture. The device includes a boat base, with its upper surface and the bottom end of a side baffle fixedly connected. One end of the upper surface of the boat base is fixedly connected to the bottom end of a water pump bracket. One end of the water pump bracket is fixedly installed on the outer surface of a water pump. One side of the outer surface of the water pump is fixedly installed on one end of a water pumping pipe, and one end of the water pumping pipe is fixedly installed on the outer surface of the water inlet. This water circulation device improves the quality of river water through a sand filter, a collection tank, a foam separator, and an aerator. It provides oxygenation during the water circulation process, improving the water quality and making it more suitable for fish survival. This solves the problem of insufficient treatment measures in the water circulation process, which hinders the improvement of aquaculture lake water quality.

[0004] Traditional sea urchin aquaculture water circulation systems can break up feed residues or other impurities in the water during aeration. If these impurities are not treated in time, they will affect water quality and thus the aquaculture. Direct filtration of water with many impurities and large water consumption is inefficient and can also filter out nutrients. Therefore, a new water circulation device for sea urchin aquaculture is proposed to solve the above problems. Utility Model Content

[0015] (III) Beneficial Effects

[0016] This invention provides a water circulation device for sea urchin farming. It has the following beneficial effects:

[0017] 1. This sea urchin aquaculture water circulation device uses a mobile motor to drive an eccentric disc to rotate, which in turn moves a moving plate, adjusting the gap between the first grid and the grid bars. When water flows from the inside of the inlet shell through the gap between the first grid and the grid bars, larger impurities in the water flow are blocked, preventing rapid clogging during filtration. By setting vertical gaps, water can still flow through from below after impurities are blocked, preventing rapid clogging. This achieves the effect of preliminary filtration of water flow by adjusting the width of the filter gaps and preventing rapid clogging of the filter gaps by impurities, solving the problem that direct filtration with excessive water flow can easily cause clogging.

[0018] 2. This sea urchin aquaculture water circulation device uses a rapidly rotating impeller inside the oxygenation chamber to agitate the water, causing it to flow and be lifted. The intake motor then draws air in quickly from the intake chamber through the air inlet pipe, allowing the air to fully contact the agitated water flow and replenish its oxygen content. The rotating water conveyor belt further increases the oxygen content, and the water undergoes initial filtration through a first grid and its bars. The water is then filtered again by the rotating water conveyor belt, improving the water composition and reducing impurities. This solves the problem of untreated impurities affecting water quality and thus aquaculture. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] This utility model embodiment provides a water circulation device for sea urchin aquaculture, such as... Figure 1-4 As shown, it includes an inlet shell 1, an impurity removal mechanism 2 is provided inside the inlet shell 1, the end face of the inlet shell 1 is fixedly connected to and passes through the oxygenation chamber 3, a flow divider 31 is provided inside the inlet end of the oxygenation chamber 3, and an anti-backflow key 32 is provided between the flow dividers 31. By providing the flow divider 31 inside the inlet end of the oxygenation chamber 3, the water flow entering the oxygenation chamber 3 is more dispersed, and the air inside the replenishment chamber 4 comes into contact with the dispersed water flow inside the oxygenation chamber 3 more quickly, so as to replenish the oxygen content in time.

[0028] The oxygenation chamber 3 is fixedly connected to the upper end of the replenishment chamber 4. The impurity removal mechanism 2 includes a casing 21. A first grid 22 is provided on the inner side of the casing 21. A moving motor 23 is fixedly connected to the upper surface of the casing 21. An eccentric disk 24 is fixedly connected to the output end of the moving motor 23. A protruding key is provided on the edge of the end face of the eccentric disk 24. A second grid 26 is provided on the outer side of the protruding key on the surface of the eccentric disk 24. A sealing cover 25 is fixedly connected to the upper end of the casing 21. The sealing cover 25 is located at the upper end of the casing 21. The impurity removal mechanism 2 can control the speed of the water flow by adjusting the gap between the first grid 22 and the second grid 26, thereby controlling the size of the impurities intercepted. When the water flows quickly, it can remove larger impurities in the water flow, preventing the subsequent filtration mechanism from being quickly blocked by larger impurities.

[0029] The upper end of the supplementary chamber 4 is fixedly connected to the striking motor 5. The upper end of the second grid 26 is a movable plate 261. The surface of the movable plate 261 is provided with vertical through holes. The vertical through holes of the movable plate 261 are sleeved on the outside of the protruding key on the surface of the eccentric disk 24. The lower end of the movable plate 261 is fixedly connected to the grid strips 262. The grid strips 262 and the first grid 22 are staggered. The second grid 26 is more convenient to adjust the distance between the grid strips 262 and the first grid 22 by setting the movable plate 261 connected to it at the upper end.

[0030] The output end of the impact motor 5 is fixedly connected to the impact wheel 6. The impact wheel 6 is inside the oxygenation chamber 3. The surface of the replenishment chamber 4 is fixedly connected to and penetrates the discharge pipe 7. The side of the replenishment chamber 4 away from the discharge pipe 7 is fixedly connected to and penetrates the air inlet pipe 8. The end of the air inlet pipe 8 away from the replenishment chamber 4 is connected to and penetrates the suction chamber 9. The suction chamber 9 is a cylindrical shell. The end face of the suction chamber 9 is provided with a filter screen. The suction chamber 9 can filter the incoming airflow and prevent impurities in the airflow from entering the water flow.

[0031] A suction motor 10 is fixedly connected to the surface of the suction chamber 9. A suction impeller 11 is fixedly connected to the output end of the suction motor 10. The suction impeller 11 is located inside the suction chamber 9. A water storage chamber 12 is connected and extends through the end of the oxygenation chamber 3 away from the access shell 1. A support plate 13 is provided on the outer side of the water storage chamber 12. A water pumping motor 14 is fixedly connected to the surface of the support plate 13. A docking tooth 15 is fixedly connected to the output end of the water pumping motor 14. A rotating shaft 16 is fixedly connected to the end face of the docking tooth 15. The rotating shaft 16 has a total... Two sets are provided. The lower rotating shaft 16 is rotatably connected to the inner wall of the water storage tank 12. A water lifting belt 17 is sleeved on the outside of the rotating shaft 16. The water lifting belt 17 is ring-shaped and has mesh holes on its surface. A holding hopper 171 is provided on the surface of the water lifting belt 17. When the water lifting belt 17 rotates, impurities can be lifted out by the holding hopper 171. The water is filtered twice by the mesh holes on the surface of the water lifting belt 17. The water is lifted by the water lifting belt 17, which improves the gas content inside the water.

[0032] The mating teeth 15 are engaged with a collision shaft 18, which is rotatably connected to the support plate 13. The collision shaft 18 is located inside the water conveyor belt 17. The collision shaft 18 includes a spur gear 181 and a camshaft 182. The surface of the spur gear 181 is engaged with the mating teeth 15. The end face of the mating teeth 15 is fixedly connected to the camshaft 182. The camshaft 182 collides and contacts the inner wall of the water conveyor belt 17. The collision shaft 18 can collide with the water conveyor belt 17 by rotating, so that the impurities stored inside the container 171 can be easily poured out to prevent the impurities from re-entering the water flow.

[0033] A booster pump 19 is connected to the lower end of the water storage tank 12. The output end of the booster pump 19 is connected to a filter chamber 20, and filter cotton is installed inside the filter chamber 20.

[0034] Working Principle: In use, water discharged from aquaculture is first fed into the inlet shell 1. The moving motor 23 drives the eccentric disc 24 to rotate, which in turn moves the moving plate 261, adjusting the gap between the first grid 22 and the grid bars 262. When water flows from the inside of the inlet shell 1 through the gap between the first grid 22 and the grid bars 262, larger impurities in the water are blocked, preventing rapid clogging during filtration. Vertical gaps allow water to flow through from below even after impurities are blocked, preventing rapid clogging. After simple filtration, the water enters the aeration chamber 3. The striking motor 5 drives the striking wheel 6 to rotate rapidly inside the aeration chamber 3, causing the water to be agitated and lifted. The suction... The motor 10 drives the suction fan 11 to rotate, causing air to quickly enter from the suction chamber 9 through the air inlet pipe 8. The air then enters the replenishment chamber 4 and comes into full contact with the impacting water flow, replenishing the oxygen content in the water flow in a timely manner. By starting the water pumping motor 14, the connecting teeth 15 are driven to rotate the water pumping belt 17, causing the holding bucket 171 to hold the water flow. The water flow flows out through the holes on the surface of the water pumping belt 17, allowing impurities in the water flow to remain inside the water pumping belt 17. The water flow is enriched with various gases by the water pumping flow. At the same time as the connecting teeth 15 rotate, the camshaft 182 collides with the water pumping belt 17, allowing impurities inside the holding bucket 171 to fall to the outside of the water storage tank 12 in a timely manner. The water flow that has undergone secondary treatment is drawn from the water storage tank 12 by the booster pump 19, filtered from the inside of the filter chamber 20, and discharged.

[0035] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
