Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, specifically to a wastewater treatment device for aquaculture. Background Technology

[0002] Aquaculture wastewater (such as wastewater discharged from aquaculture and livestock farming) contains large amounts of pollutants such as organic matter, nitrogen and phosphorus, suspended solids, and pathogenic microorganisms. Direct discharge of such wastewater can lead to environmental problems such as eutrophication and soil pollution. Aquaculture refers to the production activities of breeding, cultivating, and raising aquatic organisms such as fish, shrimp, shellfish, algae, and bullfrogs in artificially controlled aquatic environments.

[0003] Bullfrogs are amphibians with extremely high economic value. Their hind leg muscles are well-developed, with a protein content as high as 20%, resulting in a tender and delicious taste. They also possess nourishing and detoxifying properties, improving the appetite of patients with liver and lung diseases, making them very popular. Furthermore, their unique skin patterns are suitable for making high-end leather goods. Therefore, bullfrog farming is extremely developed in China. However, during bullfrog farming, the feeding and excretion of bullfrogs inevitably produce harmful impurities that pollute the entire water body. If not properly treated, these impurities will jeopardize the sustainable development of bullfrog farming. Therefore, the treatment of wastewater generated during farming is particularly important.

[0004] For example, patent application number 202420939967.5 discloses a wastewater treatment device for freshwater aquaculture, including a box body with a box cover on top, connecting grooves on both sides, connecting blocks slidably connected in the grooves, a first screen plate fixedly connected between the two connecting blocks, and a second screen plate with a smaller aperture below it. A cleaning mechanism is provided on the top of the first screen plate, a fixing mechanism is provided on the top of the box cover, and an installation mechanism is provided outside the box body. The cleaning mechanism includes a rotating shaft connected to the bottom of the box cover via a bearing.

[0005] In existing wastewater treatment devices, although impurities can be separated from the wastewater, the remaining impurities on the screen plate still need to be collected manually during the operation of the device. This not only increases the number of manual intervention steps, but also requires stopping the operation of the device during the collection process, thereby reducing the treatment efficiency and effectiveness of the wastewater.

[0006] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] In view of the problems in the related technologies, this utility model proposes a wastewater treatment device for aquaculture to overcome the above-mentioned technical problems existing in the existing related technologies.

[0010] Furthermore, in order to support the screen and collect impurities, the separation component includes a base installed inside the processing box. Two sets of support frames are symmetrically arranged on both sides of the base, and a return plate is set between the two sets of support frames. The support frames have an arched structure and a rotating groove is opened on the support frames. A collection groove that matches the collection port is opened in the middle of the base and at the bottom of one of the support frames. A return groove that matches the return plate is opened at the top of the base. A return pipe that connects to the water inlet pipe is installed through the side wall of the processing box on one side of the return groove. A water pump that connects to the return pipe is installed at the top of the processing box.

[0011] Furthermore, in order to achieve the rotation of the screen, a screen is set between the two sets of support frames. The screen is cylindrical and has screen holes on the outer circumference. One end of the screen passes through the side wall of the processing box and a motor is installed there. The output shaft of the motor is connected to the screen. A second rotating groove is set on the outer circumference of the screen and at the position of the support frame, which cooperates with the first rotating groove. Ball bearings are set between the first rotating groove and the second rotating groove.

[0012] Furthermore, in order to collect the wastewater, a water collection trough is set in the middle of the screen, and a fixed column and a connecting water pipe are set in sequence on one side of the water collection trough. The fixed column is connected to the treatment box, and a baffle is set on the outer circumference of the connecting water pipe.

[0013] Furthermore, in order to clean the screen, a support block is provided at the top of the base and between the two sets of support frames. A rotating shaft is provided between the support blocks, and a cleaning plate is sleeved on the rotating shaft. An electric telescopic rod that cooperates with the base is provided on one side of the cleaning plate, and an inclined surface is provided at the top of the cleaning plate. Several brushes that cooperate with the screen are provided on the inclined surface.

[0014] Furthermore, in order to increase the flow velocity of the tailwater in the connecting water pipe, the jet assembly includes a suction pipe sleeved above the connecting water pipe and located on one side of the baffle; a pressurizing pipe penetrating the treatment box is provided above the suction pipe, and a compressor cooperating with the pressurizing pipe is provided on one side of the pressurizing pipe and at the top of the treatment box.

[0015] Furthermore, to achieve the mixing and spraying of effluent and air, a mixing pipe is installed at one end of the suction pipe. A fixing block connected to the treatment tank is fitted around the outside of the mixing pipe. A discharge pipe connected to the mixing pipe is installed through the top of the fixing block and extends into the treatment tank. A valve is installed in the middle of the outer side of the discharge pipe, and a material cylinder is installed at the top of the discharge pipe.

[0018] 2. Through the separation component, the continuously rotating screen effectively separates impurities from the effluent, thereby ensuring the continuity of the effluent treatment process and collecting and treating impurities separately, reducing the load on subsequent treatment steps and reducing maintenance needs and repair costs.

[0019] 3. By using the jet assembly, air is used to cut the wastewater into tiny bubbles, increasing the contact area between air and water, so that the chemical agents are evenly dispersed throughout the wastewater, enhancing the reaction rate and treatment effect between the wastewater and the agents, making higher use of energy and reducing energy consumption.

[0029] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0030] According to an embodiment of the present invention, a wastewater treatment device for aquaculture is provided.

[0031] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figures 1-6As shown, the aquaculture wastewater treatment device according to an embodiment of the present invention includes a treatment tank 1, which has a hollow structure; a control panel 2, disposed on one side of the treatment tank 1; an outlet pipe 3, disposed at the bottom of the other side of the treatment tank 1; an inlet pipe 4, disposed at the top of the treatment tank 1, with one end of the inlet pipe 4 penetrating through the interior of the treatment tank 1, and a plurality of spray nozzles 5 disposed at the bottom of the inlet pipe 4 inside the treatment tank 1; a separation component 6, disposed inside the treatment tank 1, used to separate impurities contained in the wastewater; a jet component 7, disposed inside the treatment tank 1 and cooperating with the separation component, used to fully mix the wastewater with air; and a collection port 8, disposed on one side of the treatment tank 1 and cooperating with the separation component 6.

[0032] It should be noted that the start command is issued through the human-machine interface (HMI) on control panel 2, and this signal is transmitted from the HMI to the PLC programmable logic controller. Upon receiving the command, the PLC precisely controls the motor to rotate to the preset number of revolutions and drives the telescopic rod to move a set distance. This process ensures that the equipment can accurately execute various operations according to predetermined requirements, achieving high efficiency and precision in treating bullfrog tailwater. The above technology is existing technology and will not be elaborated upon further.

[0033] In one embodiment, the separation component 6 includes a base 601 disposed inside the processing tank 1. Two sets of support frames 602 are symmetrically arranged on both sides of the base 601, and a return plate 603 is disposed between the two sets of support frames 602. The support frames 602 have an arched structure and a rotating groove 604 is provided on the support frames 602. A collection groove 605 that cooperates with the collection port 8 is provided in the middle of the base 601 and at the bottom of one set of support frames 602. A return groove 606 that cooperates with the return plate is provided at the top of the base 601. A return pipe 607 that is connected to the water inlet pipe 4 is provided through the side wall of the processing tank 1 on one side of the return groove 606. A water pump 608 that is connected to the return pipe 607 is provided at the top of the processing tank 1. In addition, in specific applications, in order to expel the air in the return pipe 607 and start normal operation, the water pump 608 can be a self-priming pump. A screen 609, cylindrical in shape, is positioned between two sets of support frames 602. Screen holes 610 are provided on the outer circumference of the screen 609. A motor 611 is mounted on one end of the screen 609, penetrating the side wall of the processing box 1. The output shaft of the motor 611 is connected to the screen 609. A second rotating groove 612, cooperating with a first rotating groove 604, is located on the outer circumference of the screen 609, at the position of the support frame 602. Ball bearings 613 are positioned between the first rotating groove 604 and the second rotating groove 612. A water collection trough 614 is located in the center of the screen 609. A fixed post 615 and a connecting water pipe 616 are sequentially arranged on one side of the water collection trough 614. The fixed post 615 is connected to the processing box 1. A baffle 617 is provided on the outer circumference of the connecting water pipe 616. A support block 618 is provided at the top of the base 601 and between the two sets of support frames 602. A rotating shaft 619 is provided between the support blocks 618. A cleaning plate 620 is sleeved on the rotating shaft 619. An electric telescopic rod 621 that cooperates with the base 601 is provided on one side of the cleaning plate. An inclined surface 622 is provided at the top of the cleaning plate 620. Several brushes 623 that cooperate with the screen 609 are provided on the inclined surface 622.

[0034] It should be noted that for bullfrog tail water, the 609 sieve can be made of materials such as stainless steel or nylon, and the mesh size of the 610 sieve is approximately 40 to 60 mesh.

[0035] The working principle of the separation component 6 is as follows: The operator sends a start signal to the motor 611 through the HMI interface of the control panel 2. With the cooperation of the ball bearing 613 and the first rotating groove 604 and the second rotating groove 612, the motor 611, which receives the start signal, drives the screen 609 to rotate on the support frame. The rotating screen 609 traps impurities in the tailwater through the screen holes 610. The tailwater flows into the interior of the screen 609 and, under the action of gravity, collects in the water collection tank 614, which is fixed inside the screen 609 by the fixing column 615. It then enters the subsequent steps through the connecting water pipe 616. When the tailwater does not flow into the water collection tank 614, it flows back into the return tank 606 under the guidance of the return plate 603. Under the pumping of the water pump 608, the tailwater in the water collection tank is injected into the water inlet pipe 4 through the return pipe 607, and the separation process is repeated. Baffle 617 isolates the filtered effluent from the separation component 6. Simultaneously, the operator activates the electric telescopic rod 621, controlling the cleaning plate 620 to move slightly. When the impurities attached to the screen 609 rotate to the inclined surface 622, the electric telescopic rod 621 controls the cleaning plate 620 to gradually contact the screen 609. When the brush 623 touches the screen 609, the electric telescopic rod 621 stops moving. Under the reaction force, the rotating screen 609 causes the attached impurities to fall into the collection tank 605 through the brush 623. After the effluent treatment is completed, the operator sends a stop signal to the motor 611 and the electric telescopic rod 621 via the control panel 2. Upon receiving the stop signal, the motor 611 stops rotating, keeping the screen 609 stationary. Simultaneously, the electric telescopic rod 621 moves the cleaning plate 620 away from the screen 609. When the effluent residue in the collection tank 605 reaches its maximum accumulation, the operator uses specialized tools to clean and collect the residue through the collection port 8 for subsequent processing.

[0036] In one embodiment, the jet assembly 7 includes a suction pipe 701 sleeved above the connecting water pipe 616 and located on one side of the baffle 617; a pressurizing pipe 702 penetrating the treatment box 1 is provided above the suction pipe 701; a compressor 703 cooperating with the pressurizing pipe 702 is provided on one side of the pressurizing pipe 702 and at the top of the treatment box 1; a mixing pipe 704 is provided at one end of the suction pipe 701; a fixing block 705 connected to the treatment box 1 is sleeved on the outside of the mixing pipe 704; a discharge pipe 706 connected to the mixing pipe 704 is provided at the top of the fixing block 705 penetrating the treatment box 1; a valve 707 is provided in the middle of the outer side of the discharge pipe 706; a material cylinder 708 is provided at the top of the discharge pipe 706; and a diffuser 709 connected to the mixing pipe 704 is provided on one side of the fixing block 705. In the same direction, the diameter of the suction tube 701 gradually decreases until it connects with the mixing tube 704, while the diameter of the diffuser tube 709 gradually increases in the direction away from the mixing tube 704. Cutting strips 710 are provided inside the suction tube 701, the mixing tube 704, and the diffuser tube 709.

[0037] It should be added that the compressor 703 compresses air through mechanical action to increase its pressure, which is existing technology and will not be elaborated on again. The material cylinder 708 can contain chemical water purification agents such as alum, ferric chloride, and ferrous sulfate, and the valve 707 can use a solenoid valve to control the falling speed of the water purification agent.

[0038] The working principle of the jet assembly 7 is as follows: The operator sends a start signal to the compressor 703 via the HMI interface of the control panel 2. Upon receiving the start signal, the compressor 703 injects compressed air into the suction pipe 701 through the pressurization pipe 702, creating a vacuum effect. Driven by the airflow, the tailwater in the connecting water pipe 616 located inside the suction pipe 701 is fully mixed with the air to form a high-speed jet. When the tailwater flows into the mixing pipe 704, under the precise control of the valve 707, the falling speed of the water purification agent in the barrel 708 is controlled, ensuring thorough mixing of the water purification agent and the tailwater to form a relatively uniform mixture. The mixture then continues forward, flowing into the diffuser pipe 709. Simultaneously, under the action of the cutting strip 710, the mixture is further fully integrated. Inside the diffuser pipe 709, the mixture velocity decreases and the pressure increases, spraying the mixture out of the diffuser pipe 709 and into the treatment tank 1 for sedimentation.

[0039] To facilitate understanding of the above-mentioned technical solutions of this utility model, the working principle or operation method of this utility model in actual process will be described in detail below.

[0040] In practical application, the staff uses the inlet pipe 4 to inject the bullfrog tail water to be treated into the treatment tank 1, and then sprays the tail water evenly onto the screen 609 in the separation component 6 through the spray head 5 for solid-liquid separation. The working principle of the separation component 6 is as described above. The separated impurities are cleaned by the brush 623 and fall into the collection tank 605. The impurities are then collected and processed through the collection port 8. The separated tail water is injected into the jet component 7 through the connecting water pipe 616. The staff then starts the compressor 703 through the control panel 2. The working principle of the jet component 7 is as described above. The mixed tail water is sprayed into the treatment tank 1 through the diffuser pipe 709 for sedimentation treatment. Then, the bullfrog tail water is discharged through the outlet pipe 3.

[0041] In summary, by utilizing the above-mentioned technical solution of this utility model, impurities in bullfrog tail water can be separated from the liquid, reducing the load on subsequent treatment steps. Simultaneously, the screen automatically removes and collects impurities adhering to it while continuously operating, ensuring the continuity of tail water treatment. Furthermore, the separated tail water is cut into microbubbles via jet propulsion, increasing the contact area between air and water while fully integrating the tail water with the purification agent, enhancing the reaction rate and treatment effect. Through the separation component, the continuously rotating screen effectively separates impurities from the tail water, ensuring the continuity of the tail water treatment process and collecting and treating impurities separately, reducing the load on subsequent treatment steps, maintenance needs, and repair costs. The jet propulsion component uses air to cut the tail water into microbubbles, increasing the contact area between air and water, allowing the chemical agents to be evenly dispersed throughout the tail water, enhancing the bullfrog tail water treatment effect.
