Description

Technical Field

[0001] This utility model relates to the technical field of oxygenation and aeration devices for aquaculture farms, specifically an oxygenation and aeration device for aquaculture farms. Background Technology

[0002] Aeration devices in aquaculture farms are primarily used to increase dissolved oxygen in water. Common types include impeller aerators, microporous aerators, jet aerators, and nanotube aeration systems. Impeller aerators use a motor to drive an impeller, agitating the water and promoting oxygen dissolution through hydraulic jumps and surface renewal. Microporous aerators use a blower to compress air, releasing micron-sized bubbles through a porous structure made of materials such as EPDM rubber and ceramics, thus enhancing oxygen transfer by increasing the gas-liquid contact area. Jet aerators rely on a high-pressure water pump to generate a high-speed water flow, creating negative pressure in the mixing chamber to draw in air, achieving gas-water mixing through turbulent shearing. Nanotube aeration systems use tubular materials with nano-sized pores to generate ultra-microbubbles, utilizing the long-term retention characteristics of these bubbles to improve oxygen transport efficiency. Some devices incorporate solar power or intelligent control systems to adapt to different water depths and aquaculture densities. Their core principles all revolve around enhancing gas diffusion, extending gas-liquid contact time, or optimizing fluid mixing to achieve oxygenation.

[0003] Since aeration pipes need to operate underwater, and a large number of algae and microorganisms easily grow in the water and cover the outer wall of the aeration pipes, the failure rate of the aeration pipes is accelerated. At the same time, most existing aeration pipe air supply filtration systems use filter plate filtration structures for high-quality filtration. However, since filter plates are difficult to clean, it is necessary to provide a filtration structure to handle large dust particles in order to reduce the frequency of filter plate cleaning. Utility Model Content

[0004] The purpose of this invention is to provide an oxygenation and aeration device for aquaculture farms to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an aeration device for aquaculture farms, comprising a rearing pond, a dissolved oxygen detection device and a toxic substance detection device fixedly connected inside the rearing pond, multiple supports and aeration pipes arranged inside the supports, a covering and cleaning mechanism being provided inside the rearing pond, and an auxiliary filtration mechanism being provided on one side of the rearing pond.

[0006] The covering and cleaning mechanism includes multiple branch pipes, which are connected at both ends of the aeration pipe and fixedly connected inside the support. Each branch pipe has a rotating frame rotatably connected to its outer wall. Multiple support rods are fixedly connected between the rotating frames and are evenly distributed inside the rotating frames. One of the rotating frames has a meshing tooth fixedly connected to its outer side. A high-torque motor is fixedly connected inside the support near the meshing tooth. A gear is fixedly connected to the output end of the high-torque motor and meshes with the meshing tooth. A vortex is fixedly connected to the inner wall of the support rod and is arranged between the rotating frames. A soft brush is fixedly connected to the inner wall of the vortex and is evenly distributed inside the vortex with the spiral direction of the vortex as the reference.

[0007] Preferably, the rotating frame and the support rod are combined to form an approximate cage structure.

[0008] Preferably, the brush is fitted into the outer wall of the aeration pipe.

[0009] Preferably, the high-torque motor is equipped with a waterproof structure.

[0010] Preferably, the auxiliary filtration mechanism includes an air intake box, which is fixedly connected to one side of the aquaculture tank. A diffuser pipe and an air inlet pipe are respectively connected to both ends of the air intake box. A high-speed motor is fixedly connected inside the air intake box. A flow impeller is fixedly connected to the output end of the high-speed motor. A sponge is fixedly connected inside the air inlet pipe. A mounting bracket is fixedly connected inside the air inlet pipe. The mounting bracket is located under the sponge. A nozzle is fixedly connected to the upper surface of the mounting bracket. A water pipe is connected to the lower side of the nozzle. An air pressure pipe is connected to the diffuser pipe and the branch pipe.

[0011] Preferably, the air outlet direction of the guide impeller is close to one end of the diffuser.

[0012] Preferably, the nozzle has a tapered structure that is wider at the top and narrower at the bottom.

[0013] Compared with the prior art, this utility model provides an oxygenation and aeration device for aquaculture farms, which has the following beneficial effects:

[0014] 1. The covering cleaning mechanism is used to clean the surface of the aeration pipe. The mechanism is supported by a support base, and with the rotating frame and support rod as a bracket, the vortex can cover the outside of the aeration pipe. At the same time, the mechanism uses a large number of soft brushes attached to the inside of the vortex, so that the brushes are distributed in a spiral shape and adhere to the surface of the aeration pipe. When the vortex rotates, it can drive the brushes to evenly brush the surface of the aeration pipe, avoiding the accumulation of microorganisms that would reduce the aeration effect.

[0015] 2. The auxiliary filtration mechanism is used to assist in filtering the gas required by the aeration pipe. This mechanism can separate large dust particles in the air by using a combination of sponge and spray, avoiding the need for frequent cleaning of subsequent filter components due to rapid dust accumulation, and improving the practicality of the device.

[0027] This mechanism is used to clean microorganisms accumulated on the surface of the aeration pipe 5. It solves the problem of insufficient lifespan of traditional devices by using a rotating vortex plate 607 to drive a brush to clean the surface of the aeration pipe 5. The cleaning mechanism 6 includes multiple branch pipes 601, which are connected at both ends of the aeration pipe 5. Each branch pipe 601 is fixedly connected inside a support 4. A rotating frame 602 is rotatably connected to the outer wall of each branch pipe 601. Multiple support rods 603 are fixedly connected between the rotating frames 602, and the support rods 603 are evenly distributed inside the rotating frames 602. One of them... The rotating frame 602 is externally fixedly connected to a meshing tooth 604. A high-torque motor 605 is internally fixedly connected to a support 4 near the meshing tooth 604. A gear 606 is fixedly connected to the output end of the high-torque motor 605. The gear 606 meshes with the meshing tooth 604. A vortex 607 is fixedly connected to the inner wall of the support rod 603. The vortex 607 is arranged between the rotating frames 602. A soft brush 608 is fixedly connected to the inner wall of the vortex 607. The soft brush 608 is evenly distributed on the inner side of the vortex 607 with the spiral direction of the vortex 607 as the reference.

[0028] Furthermore, the rotating frame 602 and the support rod 603 are combined to form an approximate cage structure.

[0029] Furthermore, the brush is fitted to the outer wall of the aeration pipe 5.

[0030] Furthermore, the high-torque motor 605 is equipped with a waterproof structure.

[0031] Example 2:

[0032] This device is used to assist in filtering large particulate impurities that may be present in the air. Its water filtration method allows for a filter plate structure that reduces the frequency of cleaning. Please refer to [link / reference]. Figure 1-5 Furthermore, in conjunction with Embodiment 1, the auxiliary filtration mechanism 7 includes an air intake box 701, which is fixedly connected to one side of the aquaculture tank 1. A diffuser pipe 702 and an air inlet pipe 703 are respectively connected to both ends of the air intake box 701. A high-speed motor 704 is fixedly connected inside the air intake box 701. A flow guide impeller 705 is fixedly connected to the output end of the high-speed motor 704. A sponge 706 is fixedly connected inside the air inlet pipe 703. A mounting bracket 707 is fixedly connected inside the air inlet pipe 703. The mounting bracket 707 is located below the sponge 706. A nozzle 708 is fixedly connected to the upper surface of the mounting bracket 707. A water pipe 709 is connected to the lower side of the nozzle 708. An air pressure pipe 710 is connected inside the diffuser pipe 702 and the branch pipe 601.

[0033] Furthermore, the air outlet direction of the impeller 705 is set to be close to one end of the diffuser 702.

[0034] Furthermore, the nozzle 708 features a tapered structure that is wider at the top and narrower at the bottom.

[0035] In actual operation, when this device is in use, the user starts the high-speed motor 704 when oxygen is needed in the aeration tank 1. The high-speed motor 704 outputs airflow through impeller cutting and pushing, creating air pressure inside the draft box 701. Due to the design of the draft impeller 705, a negative pressure airflow is generated at the air inlet pipe 703. After entering the air inlet pipe 703, the user provides water pressure to the nozzle 708, enabling it to produce a spray. This spray wets the sponge 706, allowing the negative pressure airflow passing through the sponge 706 to interact with the seawater. The ample contact between water vapor and sponge 706 helps retain large dust particles on the sponge 706. The negative pressure airflow passes through fine filtration and then enters the aeration pipe 5. When the user needs to clean the aeration pipe 5, the user can activate the high-torque motor 605. The output of the high-torque motor 605 drives the rotating frame 602 to rotate. When the rotating frame 602 rotates, it drives the vortex 607 to rotate. When the vortex 607 rotates, it drives the brush to clean away the microorganisms accumulated on the surface of the aeration pipe 5, thereby reducing the possibility of clogging and enabling the aeration pipe 5 to work more efficiently and for longer.
