[0002] In current aquaculture technology, fish farming is extremely important. Whether in fishponds or aquariums, large amounts of uneaten feed and animal excrement generate significant amounts of pollutants such as ammonia nitrogen, nitrite, and sulfides. These pollutants not only pollute water bodies, making wastewater turbid and affecting the health of organisms, but also reduce the survival rate of farmed fish.

[0003] Existing aquaculture filtration devices mostly use fixed filter screens or built-in filter media chambers, which require frequent manual cleaning after a large amount of particulate impurities accumulate.

[0004] In addition, there are single-stage filters, which are difficult to handle high levels of organic matter and require large amounts of water to be changed and replenished with fresh water. Utility Model Content

Detailed Implementation

[0033] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be given below with reference to the accompanying drawings, which show several embodiments of the utility model. However, the utility model can be implemented in different forms and is not limited to the embodiments described in the text. On the contrary, these embodiments are provided to make the disclosure of the utility model more thorough and comprehensive.

[0034] According to the appendix Figures 1 to 6 As shown, this utility model provides an independent external water filtration device for aquaculture, the filtration device comprising:

[0035] Aquaculture pond 1, used for aquaculture of fish, is supplied with fresh water through the main water supply pipe 2. The external water supply pump unit 3 provides the power for water intake. When aquaculture pond 1 needs to be drained as a whole, the water and most of the impurities in the pond are discharged by opening the drain valve 4. This completes the water change in the aquaculture pond 1 in a common way and cleans the pond. For water change requirements, water quality monitoring equipment is usually installed in aquaculture pond 1 to make data-based judgments on water quality standards. When the water quality is lower than a certain standard, the whole water needs to be changed. This method is not directly related to whether purification or filtration is carried out. Water purification or filtration is an auxiliary function. Its main effect is to extend the life of water quality, but it cannot ensure that it can be used indefinitely.

[0036] The scheme also includes a filtration inlet pipe 5 leading from the inside of the aquaculture pond 1 to the outside. A suction pump unit 54 (a conventional underwater submersible suction pump can be used, with flow rate, head, and power sufficient to meet the water pumping needs from the bottom of the pond) is installed on the inner wall of the aquaculture pond 1 near the bottom. The suction pump unit 54 draws water from the pond and sends it to the filtration mechanism 7 via the filtration inlet pipe 5. The filtration mechanism 7 includes an upper filter box 71 and a lower filter box 72 stacked on top of each other, which are detachably connected.

[0037] The filter inlet pipe 5 is located in the middle section of the pipe and has a U-shaped path structure. A manual stop valve 51 is installed on the pipe near the bottom of the U-shaped section. This section of the pipe can use a transparent water pipe. It is mainly used to manually disconnect the water circuit. In addition, it can also be used to disassemble and clean up large impurities after they have accumulated, so as to prevent them from being directly sent to the smaller diameter spray head 533 and causing blockage, which could lead to pipe bursting or water pump burnout.

[0038] One end of the filter inlet pipe 5 is connected to the first branch pipe 52 for water flow. The first branch pipe 52 is placed vertically inside the upper filter box 71, and the second branch pipe 53 is placed horizontally above the upper filter box 71. The pipe structures of the first branch pipe 52 and the second branch pipe 53 are both U-shaped, and the two ends of the second branch pipe 53 and the two ends of the first branch pipe 52 intersect and connect for water flow.

[0039] The first diversion pipeline 52 includes a support top connector 521 located above the upper filter box 71 and a support bottom connector 527 located at the bottom of the upper filter box 71. A top connector connecting pipe section 522 is fixed below the support top connector 521. A nut 523 is threaded to the lower end of the top connector connecting pipe section 522. A connecting cap 524 is movably sleeved inside the bottom of the nut 523. A first bearing 5241 is embedded and fixed inside the connecting cap 524. An upper connecting shaft 5242 is inserted and fixed inside the first bearing 5241. An upper connecting flange 5243 is connected to the bottom of the upper connecting shaft 5242.

[0040] A bottom connector connecting pipe section 526 is fixed on the bottom connector 527. A second bearing 5261 is embedded and fixed on the inner wall of the top of the bottom connector connecting pipe section 526. A lower connecting shaft 5263 is inserted and fixed inside the second bearing 5261. A lower connecting flange 5262 is connected to the top of the lower connecting shaft 5263. The upper connecting flange 5243 and the lower connecting flange 5262 are fixed by bolts. A sealing ring is provided on the surface between the two.

[0041] The upper filter box 71 is also equipped with a rotatable filter basket 525. The upper part of the filter basket 525 is a cylindrical structure, and the lower part is tapered into a frustum structure. Both the cylindrical part and the part of the frustum structure near the cylindrical part are provided with dense mesh areas for filtering impurities in the water. When in use, a mesh bag with smaller pores for finer filtration can be placed inside the filter basket 525. A basket bottom through hole area 5251 is opened on the frustum structure at the bottom of the filter basket 525. When the filter basket 525 is installed, the basket bottom through hole area 5251 should be located between the sealing rings on the upper connecting flange 5243 and the lower connecting flange 5262. After the bolts are tightened, the upper and lower sealing rings press against the edge of the basket bottom through hole area 5251 for compression and sealing.

[0042] The second diversion pipe 53 consists of multiple diversion intermediate pipes 531 and elbow joints. A three-way joint is also installed on the diversion intermediate pipe 531. There are four three-way joints, which are evenly distributed around the top of the filter basket 525. An extension pipe 532 is connected to the inside of each three-way joint. A spray head 533 is installed on the extension pipe 532. The water trajectory of the spray head 533 can impact the inner wall of the filter basket 525. By using the simultaneous needle-shaped water flow impact, the filter basket 525 is driven to rotate while filtering.

[0043] The bottom of the upper filter box 71 is a multi-pore bottom plate 711. A sponge block 712 is also placed inside the box. The sponge block 712 has through holes 7121 at the middle and both ends. The sponge block 712 is cut open along the center line of the three through holes 7121. When placed in the upper filter box 71, it can be placed separately on both sides of the box and brought together in the middle. The through holes 7121 are used to avoid the corresponding pipes on the first diversion pipe 52 and the bottom connector connecting pipe section 526.

[0044] The lower filter box 72 has an opening at the top, and an annular protrusion 722 is provided on the inner wall near the opening. The bottom of the upper filter box 71 is placed on the annular protrusion 722. A hollow trapezoidal platform 723 is provided at one end of the space below the annular protrusion 722, and a temporary water storage area 721 is provided at the other end. A sloping fine filter plate 724 is provided on the inclined surface of the hollow trapezoidal platform 723 near the temporary water storage area 721. A water outlet pump unit 725 is provided inside the hollow trapezoidal platform 723 (a conventional underwater submersible suction pump can be selected, with its flow rate, head, and power sufficient to meet the water pumping requirements of the current box). The wiring terminal of the water outlet pump unit 725 passes through the shell of the lower filter box 72. The body extends to the outside for power cord connection, and the outlet of the water pump unit 725 also extends through the housing of the lower filter box 72 to the outside and is connected to the filter outlet pipe 6. The outlet of the filter outlet pipe 6 leads to the aquaculture pond 1 through the pipe, and together with the filter inlet pipe 5, the water is filtered and circulated to form a water circulation, and the water is reused after filtration and purification, saving water resources. In addition, a water level sensor 726 (a conventional submersible liquid level monitoring sensor type can be selected) is installed through the housing outside the opening at the top of the lower filter box 72 to monitor the water level in the lower filter box 72, prevent the water level from exceeding the limit, and transmit the data signal to the corresponding controller in real time.

[0045] It should be noted that in this device, the upper part of the first diversion pipe 52 is water-conducting, that is, the pipes supporting the top connector 521 and connecting its two ends extend to the connection with the second diversion pipe 53. The lower part is not water-conducting, that is, the pipes connecting to the two ends of the lower supporting bottom connector 527 are not water-conducting. The water flow sequence is that the water coming in from the filter inlet pipe 5 flows through the first diversion pipe 52 from both ends to the second diversion pipe 53, and finally sprays out from the spray head 533 and enters the filter basket 525.

[0046] The specific working principle of this utility model is as follows:

[0047] Filtration water intake process: A suction pump unit 54 is installed on the inner wall near the bottom of the aquaculture pond 1. The wiring terminals of the suction pump unit 54 can extend through the aquaculture pond 1 to the outside for power connection. In the entire control system, a controller used for automation on the market is used as the control center equipment, which is connected to the electrical control components at various locations via wires. Operated by personnel, the suction pump unit 54 is turned on to draw water from the pond and send it to the filtration mechanism 7 through the filtration water intake pipe 5. The middle section of the filtration water intake pipe 5 has a U-shaped path structure, and a manual stop valve 51 is installed on the pipe near the bottom of the U-shaped section. This section of the pipe can be made of transparent water pipe. Under normal circumstances, the manual stop valve 51 is in the open state for water flow during filtration operation.

[0048] Working mechanism of the diversion pipeline and filter basket: One end of the filter inlet pipeline 5 is connected to the first diversion pipeline 52 for water flow, which in turn connects the second diversion pipeline 53 for water flow. The water jets 533 on the second diversion pipeline 53 can impact the inner wall of the filter basket 525 with their water jet trajectory. Utilizing the simultaneous directional water jet impact, the filter basket 525 rotates while filtering. A mesh bag can be installed inside the filter basket 525 at this point, or it can be left uninstalled, depending on the filtration requirements.

[0049] Filtration process of upper and lower filter boxes: Water filtered by the filter basket 525 in the upper filter box 71 flows through the sponge block 712 and then into the lower filter box 72 via the multi-pore bottom plate 711. Ordinary sand or quartz sand can be added to the temporary water storage area 721 for filtration. The inclined fine filter plate 724 on the hollow trapezoidal platform 723 draws the water after multiple filtrations from the outlet pump unit 725 and returns it to the aquaculture pond 1 through the filtered water outlet pipe 6.

[0050] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
