Description

Technical Field

[0001] This utility model relates to the field of aquaculture pond technology, specifically a low-pressure oxygenation device for aquaculture ponds. Background Technology

[0002] Aquaculture ponds are essential facilities used in aquaculture for raising aquatic organisms such as fish, shrimp, and crabs. Depending on the materials, structure, and purpose, aquaculture ponds can be classified into various types, such as canvas aquaculture ponds, PVC aquaculture ponds, and fiberglass aquaculture ponds.

[0003] Low-pressure aerators are needed in aquaculture ponds. These aerators use electric motors or diesel engines to rapidly transfer oxygen from the air into the pond. When the pond is low in oxygen, turning on the low-pressure aerator can prevent fish and shrimp from surfacing. On sunny days when dissolved oxygen levels are high in the upper layers, turning on the aerator accelerates water convection, increasing dissolved oxygen in the middle and lower layers, which is beneficial for rapid fish and shrimp growth, reduces the feed conversion ratio, promotes the oxidation and decomposition of organic matter, and reduces disease occurrence. Furthermore, the circulating water also promotes the reproduction and growth of plankton, increasing the pond's primary productivity. Therefore, the function of low-pressure aerators is not only to oxygenate the water but also to improve the pond's primary productivity and self-purification capacity, thereby improving the pond's water quality and ecological environment. The resulting water circulation has a positive effect on promoting the healthy and rapid growth of fish and shrimp.

[0004] In practice, aeration and chemical treatment in aquaculture ponds are usually carried out asynchronously, with chemical application typically done manually by staff. This method is inefficient, and when the aeration grid and chemical dosage are not synchronized, the dissolved oxygen content in the water may become mismatched with the chemical concentration. This affects the reaction rate and efficiency of the chemical in the water, thus severely impacting the overall effectiveness of the treatment system. Therefore, a low-pressure aeration device for aquaculture ponds is proposed to address the aforementioned problems. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a low-pressure aeration facility for aquaculture ponds, which has the advantages of strong applicability and the ability to synchronize aeration and medication application, thus solving the problem that aeration and medication application in ponds are not convenient to be carried out simultaneously.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a low-pressure aeration facility for aquaculture ponds, comprising an aeration device for low-pressure aeration of the aquaculture pond, the aeration device consisting of an isolation frame, a grid and a low-pressure aerator, the low-pressure aerator being provided with an external mounting frame for support, the mounting frame being provided with a drug delivery structure, and a linkage structure being provided between the drug delivery structure and the low-pressure aerator;

[0007] The grille includes four connecting pipes and four low-pressure pipes. The four connecting pipes are arranged in a rectangular shape. The two ends of the four low-pressure pipes are fixedly connected to the two ends of the four connecting pipes respectively. Several nozzles are fixedly connected to the front and rear sides of the four low-pressure pipes at equal intervals.

[0008] The drug delivery structure includes a gear pump, a three-way pipe fixedly installed on the mounting frame and connected to the drug delivery structure and the low-pressure oxygenator, and a delivery pipe connected to the grid is fixedly connected to the end of the three-way pipe away from the drug delivery structure and the low-pressure oxygenator.

[0009] The linkage structure consists of a connecting shaft, a synchronous pulley, and a synchronous belt tensioner.

[0010] Furthermore, a locking clamp for fixing is installed on the outside of the low-pressure pipe at the bottom. There are multiple grids, and each of the two adjacent conveying pipes has a connecting hole inside. A connecting pipe that connects the two grids is inserted between the two opposite connecting holes.

[0011] Furthermore, the gear pump includes a pump housing fixedly mounted on the upper surface of the mounting bracket and two gears rotatably disposed inside the pump housing. A fixed seat for supporting the three-way pipe is mounted on the upper surface of the mounting bracket.

[0012] Furthermore, a pump chamber is provided inside the pump casing, and two gears are meshed and rotated inside the pump chamber. Water pipes are fixedly connected to both the left and right sides of the pump casing. The two water pipes are connected to the pump chamber at opposite ends and to the medicine tank and one end of the three-way pipe at opposite ends, respectively.

[0013] Furthermore, there are two synchronous pulleys and two connecting shafts. The two synchronous pulleys are rotatably mounted on the ends of the two connecting shafts, and the other ends of the two connecting shafts are respectively connected and fixed to the impeller of the low-pressure aerator and one of the gears.

[0014] Furthermore, the tensioning component includes a mounting plate that slides through the interior of the mounting frame, a tensioning wheel that is rotatably mounted on the top of the mounting plate and is rolledly connected to the timing belt, a horizontal plate welded to the bottom of the mounting plate, and an electric push rod that is fixedly mounted between the upper surface of the horizontal plate and the lower surface of the mounting frame.

[0015] Furthermore, the mounting bracket has a through hole inside, and a sliding groove is formed inside the through hole. The mounting plate passes through the inside of the mounting bracket through the through hole, and a guide block that is slidably connected to the sliding groove is installed on the front of the mounting plate.

[0016] Compared with the prior art, this utility model provides a low-pressure aeration device for aquaculture ponds, which has the following beneficial effects:

[0017] 1. This aquaculture pond uses a low-pressure aeration system. Through a linkage structure, the gear pump and the low-pressure aerator operate synchronously. The injected chemicals promote the dissolution of oxygen in the water. Combined with the aeration function of the aeration grid, it can further increase the dissolved oxygen content of the water, thereby meeting the oxygen requirements of aquatic organisms. Some chemicals can be used to adjust the pH value of the water and remove harmful substances such as ammonia nitrogen and nitrite. When used simultaneously with the aeration grid, it can improve water quality while increasing oxygen, creating a more suitable living environment for aquatic organisms.

[0018] 2. This aquaculture pond uses a low-pressure aeration system, which utilizes low-pressure mixing, multiple screens, and multiple water outlets to achieve energy-saving aeration. When in use, the low-pressure aerator is started to supply air to the screens, and oxygen is released through tiny nozzles to increase the contact area between oxygen and water, improve oxygen mass transfer efficiency, and the tiny nozzle design helps to reduce the rising speed of bubbles and prolong the residence time of oxygen in the water, thereby enhancing the aeration effect.

Detailed Implementation

[0024] 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.

[0025] Please see Figures 1 to 4 A low-pressure aeration facility for aquaculture ponds includes aeration equipment for low-pressure aeration of the pond. The aeration equipment consists of an isolation frame 1, a grid 2, and a low-pressure aerator 3. The low-pressure aerator 3 is externally supported by a mounting frame 8. The grid 2 includes four connecting pipes 201 and four low-pressure pipes 202. The four connecting pipes 201 are rectangular, and both ends of the four low-pressure pipes 202 are fixedly connected to the ends of the four connecting pipes 201. Several equidistant nozzles 203 are fixedly connected to both the front and rear sides of the four low-pressure pipes 202. The nozzles 203 are micro-sized. When the low-pressure aerator 3 is activated, air is supplied to the grid 2, and oxygen is released through the micro-nozzles 203, increasing the contact area between oxygen and water, improving oxygen mass transfer efficiency. The micro-nozzle design helps reduce the rising speed of air bubbles and prolongs the residence time of oxygen in the water, thereby enhancing the aeration effect. The isolation frame 1 is perforated and is bolted into the aquaculture pond.

[0026] In this embodiment, a locking clamp 206 for fixing is installed on the outside of the bottom low-pressure pipe 202. There are multiple grids 2, and each of the two adjacent conveying pipes 4 has a connecting hole 204. A connecting pipe 205 connecting the two grids 2 is inserted between the two opposite connecting holes 204.

[0027] To improve the oxygenation effect, in this embodiment, a drug delivery structure is provided on the mounting frame 8, and a linkage structure 7 is provided between the drug delivery structure and the low-pressure oxygenator 3; the drug delivery structure includes a gear pump 6 and a three-way pipe 5 fixedly installed on the mounting frame 8 and connected to the drug delivery structure and the low-pressure oxygenator 3, and the end of the three-way pipe 5 away from the drug delivery structure and the low-pressure oxygenator 3 is fixedly connected to a conveying pipe 4 connected to the grid 2; the linkage structure 7 consists of a connecting shaft 701, a synchronous pulley 702, and a synchronous belt 703 tensioning member.

[0028] Specifically, the gear pump 6 includes a pump housing 601 fixedly mounted on the upper surface of the mounting bracket 8 and two gears 603 rotatably disposed inside the pump housing 601. A fixing seat 51 supporting the three-way pipe 5 is mounted on the upper surface of the mounting bracket 8. A pump chamber 602 is opened inside the pump housing 601. The two gears 603 mesh and rotatably mount inside the pump chamber 602. Water delivery pipes 604 are fixedly connected to both the left and right sides of the pump housing 601. One end of the two water delivery pipes 604 is connected to the pump chamber 602, and the other ends are fixedly connected to the medicine tank and one end of the three-way pipe 5, respectively.

[0029] It is understandable that the gear pump 6 and the low-pressure aerator 3 are synchronized through the linkage structure 7. The delivered chemicals have the effect of promoting the dissolution of oxygen in the water. Combined with the oxygenation function of the oxygenation grid 2, the dissolved oxygen in the water can be further increased, thereby meeting the oxygen demand of aquatic organisms. The higher the power of the low-pressure aerator 3, the higher the speed of the gear pump 6 can be achieved by the transmission cooperation of the synchronous pulley 702 and the synchronous belt 703, thereby improving the liquid delivery efficiency.

[0030] In this embodiment, there are two synchronous pulleys 702 and two connecting shafts 701. The two synchronous pulleys 702 are rotatably mounted on the ends of the two connecting shafts 701, and the other ends of the two connecting shafts 701 are respectively connected and fixed to the impeller of the low-pressure aerator 3 and one of the gears 603.

[0031] The tensioning component includes a mounting plate 705 that slides through the interior of the mounting frame 8, a tensioning wheel 704 that is rotatably mounted on the top of the mounting plate 705 and rolledly connected to the synchronous belt 703, a horizontal plate 706 welded to the bottom of the mounting plate 705, and an electric push rod 707 fixedly mounted between the upper surface of the horizontal plate 706 and the lower surface of the mounting frame 8. The tensioning component can adjust the tension of the synchronous belt 703, thereby realizing the transmission between the drug delivery structure and the low-pressure aerator 3.

[0032] It should be noted that the mounting bracket 8 has a through hole inside, and a sliding groove is provided inside the through hole. The mounting plate 705 passes through the through hole into the interior of the mounting bracket 8, and a guide block 708 that is slidably connected to the sliding groove is installed on the front of the mounting plate 705.

[0033] The working principle of the above embodiments is as follows:

[0034] In use, the low-pressure aerator 3 is started to supply air to the screen 2, and oxygen is released through tiny nozzles 203, increasing the contact area between oxygen and water and improving oxygen mass transfer efficiency. The tiny nozzle design helps to reduce the rising speed of bubbles and prolong the residence time of oxygen in water, thereby enhancing the oxygenation effect. At the same time, the gear pump 6 and the low-pressure aerator 3 are synchronized through the linkage structure 7. The delivered chemicals have the effect of promoting the dissolution of oxygen in the water. Combined with the oxygenation function of the aeration screen 2, the dissolved oxygen content of the water can be further increased, thereby meeting the oxygen requirements of aquatic organisms.

Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply.
