Description

Technical Field

[0001] This utility model relates to the field of aquaculture, and in particular to a combined ultraviolet sterilization and dissolved oxygen device for aquaculture. Background Technology

[0002] Aquaculture, as an important component of fisheries, is directly affected by water quality in terms of both profitability and quality. Good water quality not only provides a suitable living environment for aquatic organisms, promoting their healthy growth, but also effectively reduces disease incidence and increases yield and economic benefits. Therefore, effective dissolved oxygenation and sterilization treatment of aquaculture water is a crucial step in the aquaculture process.

[0003] In traditional aquaculture, dissolved oxygen treatment typically employs simple aeration equipment such as aeration discs, aeration heads, or aerators. While these devices can increase dissolved oxygen levels in the water to some extent, they have significant limitations. The bubbles produced by aeration equipment are relatively large, resulting in limited contact area with the water and low oxygen dissolution efficiency, making it difficult to meet the high dissolved oxygen requirements of large-scale aquaculture. Furthermore, uneven aeration can easily lead to localized areas of excessively high or low dissolved oxygen, negatively impacting the growth and survival of aquatic organisms.

[0004] In terms of sterilization, traditional methods often use chemical disinfectants, such as bleaching powder and copper sulfate. While chemical disinfectants can effectively kill harmful microorganisms in water, they leave chemical residues that can pose a potential threat to aquatic organisms, affecting their quality and safety. Furthermore, long-term use of chemical disinfectants can disrupt the ecological balance of aquatic bodies, leading to a reduction in the number of beneficial microorganisms and further impacting water quality stability.

[0005] To improve water treatment efficiency, some existing technologies attempt to integrate dissolved oxygen and sterilization functions into the same device. However, these devices have shortcomings in water flow dispersion and treatment. Specifically, the water flow cannot be evenly distributed within the treatment space, resulting in insufficient contact between oxygen and water, and the dissolved oxygen efficiency cannot be significantly improved. Furthermore, the ultraviolet sterilization lamps cannot fully cover the water flow, leading to unsatisfactory sterilization effects and failing to effectively guarantee the quality of aquaculture water.

[0006] Therefore, it is necessary to provide a new ultraviolet sterilization and dissolved oxygen combined device for aquaculture to solve the above-mentioned technical problems. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model provides a combined ultraviolet sterilization and dissolved oxygen device for aquaculture.

[0008] This utility model provides a combined ultraviolet sterilization and dissolved oxygen device for aquaculture, comprising: a base, on which a treatment tank is fixedly connected, an inlet pipe at the top of the treatment tank, an oxygen pump installed on the side wall of the base, an oxygen delivery pipe fixedly connected to the outlet of the oxygen pump, and the oxygen delivery pipe connected to the tank wall of the treatment tank; and a dispersion treatment mechanism, comprising a connecting pipe rotatably connected to the top wall of the treatment tank, a central disc at the lower end of the connecting pipe, multiple blade-shaped diffusers on the central disc, a rotary joint installed between the connecting pipe and the inlet pipe, and a centrifugal assembly between the connecting pipe and the upper end of the treatment tank.

[0009] Preferably, each of the plurality of leaf blades has a flat opening at one end.

[0010] Preferably, the centrifugal assembly includes a gear ring, which is fixedly connected to the upper end of the connecting pipe. A short shaft is provided on one side of the gear ring, and a mating gear is fixedly connected to the short shaft. The mating gear meshes with the gear ring.

[0011] Preferably, a motor is installed and connected to the top wall of the treatment tank, the output end of the motor is fixedly connected to a short shaft, and the lower end of the short shaft is rotatably connected to the top wall of the treatment tank.

[0012] Preferably, an ultraviolet germicidal lamp ring is installed and connected to the top of the treatment tank, and a transparent protective shell is installed and connected to the outside of the ultraviolet germicidal lamp ring.

[0013] Preferably, an oxygen outlet ring is provided at the middle position of the treatment tank, the oxygen outlet ring has multiple oxygen outlets, an extension pipe is fixedly connected to the oxygen outlet ring, one end of the extension pipe is fixedly connected to the connecting pipe, and an umbrella-shaped water baffle is provided above the oxygen outlet ring, the umbrella-shaped water baffle is fixedly connected to the inner wall of the treatment tank through a mounting bracket.

[0014] Preferably, the treatment tank is provided with a water outlet at the bottom, and a drain pipe is installed and connected on the base, with one end of the water outlet connected to the drain pipe.

[0015] Compared with related technologies, the ultraviolet sterilization and dissolved oxygen combined device for aquaculture provided by this utility model has the following beneficial effects:

[0016] 1. This utility model utilizes a unique dispersion treatment mechanism. After the water flows through the inlet pipe into the connecting pipe, it is discharged through the flat opening at one end of multiple blade-shaped diffusers. This allows the water flow to be evenly dispersed, presenting a flat water jet. The water flow is evenly distributed within the treatment tank, ensuring that the oxygen released by the oxygenating ring can fully contact the water, greatly improving dissolved oxygen efficiency. This creates a high-oxygen, high-quality living environment for aquatic organisms, helping to enhance their vitality and growth rate. Furthermore, due to the even dispersion of the water flow, the ultraviolet sterilization lamp ring can fully cover and kill harmful microorganisms in the water, reducing the chance of disease in aquatic organisms. This fundamentally improves the water quality treatment effect and strongly promotes the healthy growth of aquatic organisms. Compared with traditional water treatment methods, the survival rate of aquatic organisms is significantly improved.

[0017] 2. This utility model drives the short shaft to rotate through the motor output end. The mating gear and gear ring fixedly connected to the short shaft mesh with each other. Since the gear ring is fixed to the upper end of the connecting pipe, this meshing transmission allows the connecting pipe to rotate relative to the top wall of the treatment tank. The central disk and multiple blades set at the lower end of the connecting pipe then perform circumferential motion. Under the action of centrifugal force, the water flow is spread out in a flat shape to the surrounding area of ​​the treatment tank. This allows the flat sprayed water flow to further extend the spraying distance and area under the action of rotational centrifugal force, thus making the contact time with the ultraviolet germicidal lamp longer.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please refer to the following: Figures 1 to 3A combined ultraviolet sterilization and dissolved oxygen device for aquaculture includes: a base 1, a treatment tank 2 fixedly connected to the base 1, an inlet pipe 21 at the top of the treatment tank 2, an oxygen pump 3 installed on the side wall of the base 1, an oxygen supply pipe 31 fixedly connected to the outlet of the oxygen pump 3, and the oxygen supply pipe 31 connected to the tank wall of the treatment tank 2; a dispersion treatment mechanism, including a connecting pipe 4, which is rotatably connected to the top tank wall of the treatment tank 2, a central disc at the lower end of the connecting pipe 4, multiple leaf blades 41 on the central disc, a rotary joint 42 installed between the connecting pipe 4 and the inlet pipe 21, and a centrifugal assembly between the connecting pipe 4 and the upper end of the treatment tank 2.

[0024] In the specific implementation process, such as Figure 1 and Figure 2 As shown, each of the multiple leaf blades 41 has a flat opening at one end.

[0025] It should be noted that when the water flows from the connecting pipe 4 through the central disc to the flat blades 41, the flat nozzle can shape the water flow, causing the water to spray out in a flat shape. Compared with the circular outlet, the flat nozzle increases the contact area between the water flow and the air and the surrounding water.

[0026] In the oxygen dissolution process, this helps more oxygen dissolve into the water, thus improving oxygen dissolution efficiency.

[0027] During the ultraviolet sterilization stage, the larger contact area allows the water flow to receive ultraviolet radiation more comprehensively, enhancing the sterilization effect, effectively reducing the number of harmful microorganisms in the water, and improving the quality of water treatment.

[0028] refer to Figure 1 and Figure 3 As shown, the centrifugal assembly includes a gear ring 5, which is fixedly connected to the upper end of the connecting pipe 4. A short shaft 51 is provided on one side of the gear ring 5, and a mating gear 52 is fixedly connected to the short shaft 51. The mating gear 52 meshes with the gear ring 5.

[0029] It should be noted that the fixed connection between the gear ring 5 and the upper end of the connecting pipe 4 ensures that the two can move synchronously. The meshing transmission between the short shaft 51 and the gear 52 and the gear ring 5 accurately transmits the rotational power of the motor 53 to the connecting pipe 4, which can ensure the stable rotation of the connecting pipe 4, thereby making the central disk and the blade 41 move smoothly in a circular motion, providing a stable centrifugal force for the water flow, realizing the uniform dispersion of the water flow, and ensuring the efficient operation of the entire device.

[0030] refer to Figure 3 As shown, a motor 53 is installed on the top wall of the treatment tank 2. The output end of the motor 53 is fixedly connected to the short shaft 51, and the lower end of the short shaft 51 is rotatably connected to the top wall of the treatment tank 2.

[0031] It should be noted that the output end of motor 53 is fixed to short shaft 51, which can directly transmit the rotational motion of motor 53 to short shaft 51. The lower end of short shaft 51 is rotatedly connected to the top wall of the processing tank 2, which provides stable support for short shaft 51 and ensures that it can rotate smoothly under the drive of motor 53.

[0032] By precisely controlling the rotation speed of the motor 53, the rotation speed of the connecting pipe 4 can be flexibly adjusted, thereby controlling the degree of water flow dispersion and the spraying range.

[0033] refer to Figure 1 and Figure 2 As shown, an ultraviolet germicidal lamp ring 6 is installed and connected at the top of the treatment tank 2, and a transparent protective ring shell 61 is installed and connected to the outside of the ultraviolet germicidal lamp ring 6.

[0034] It should be noted that the ultraviolet germicidal lamp ring 6 is installed at the top of the treatment tank 2, which can provide comprehensive ultraviolet irradiation to the sprayed water flow, effectively killing harmful microorganisms in the water;

[0035] The transparent protective ring shell 61 is made of transparent material, which can effectively block water from corroding the ultraviolet germicidal lamp ring 6, prevent the lamp ring from short-circuiting or being damaged due to long-term contact with water, extend its service life, and ensure that ultraviolet rays can penetrate smoothly without affecting the sterilization effect.

[0036] refer to Figure 1 and Figure 2 As shown, an oxygen outlet ring 7 is provided in the middle of the treatment tank 2. The oxygen outlet ring 7 has multiple oxygen outlets. An extension pipe 71 is fixedly connected to the oxygen outlet ring 7. One end of the extension pipe 71 is fixedly connected to the connecting pipe 4. An umbrella-shaped water baffle 72 is provided above the oxygen outlet ring 7. The umbrella-shaped water baffle 72 is fixedly connected to the inner wall of the treatment tank 2 through a mounting bracket.

[0037] It should be noted that: the multiple oxygen outlets on the oxygen outlet ring 7 can evenly release the compressed air delivered by the oxygen supply pipe 31 and combine it with the water flow to achieve efficient oxygen dissolution; the extension pipe 71 is connected to the connecting pipe 4; the umbrella-shaped water baffle 72 is fixed to the inner wall of the treatment tank 2 by the mounting bracket and is located above the oxygen outlet ring 7. Its umbrella-shaped structure can effectively block the water flow from directly impacting the oxygen outlet ring 7, ensuring that oxygen can be continuously and stably dissolved in the water and improving the oxygen dissolution effect.

[0038] refer to Figure 1 and Figure 2 As shown, the bottom of the treatment tank 2 is provided with a water outlet, and a drain pipe 8 is installed on the base 1, with one end of the water outlet connected to the drain pipe 8.

[0039] It should be noted that the water from the outlet at the bottom of the treatment tank 2 and the drain pipe 8 connected to it, after being treated with dissolved oxygen and sterilization, flows out from the outlet and is discharged back to the breeding area through the drain pipe 8.

[0040] The working principle of the ultraviolet sterilization and dissolved oxygen composite device for aquaculture provided by this utility model is as follows: First, the aquaculture water is input into the treatment tank 2 through the water inlet pipe 21. At the same time, the oxygen pump 3 installed on the side wall of the base 1 starts to work, compresses the air and pumps it into the treatment tank 2 through the oxygen supply pipe 31. The oxygen supply pipe 31 is connected to the oxygen outlet ring 7 in the middle of the treatment tank 2. The oxygen outlet ring 7 has multiple oxygen outlets. The compressed air is evenly released into the interior of the treatment tank 2 in the form of tiny bubbles through these oxygen outlets, realizing the initial dissolved oxygen process.

[0041] When motor 53 starts, its output drives short shaft 51 to rotate. The gear 52 fixedly connected to short shaft 51 meshes with gear ring 5. Since gear ring 5 is fixed to the upper end of connecting pipe 4, this meshing transmission allows connecting pipe 4 to rotate relative to the top wall of treatment tank 2. The central disk and multiple blades 41 set at the lower end of connecting pipe 4 then perform circular motion. The water flowing into connecting pipe 4 from water inlet pipe 21 is dispersed in a flat shape to the periphery of treatment tank 2 under the action of centrifugal force. The flat opening at one end of blade 41 further enhances the dispersion effect of water flow, allowing water flow to be more evenly distributed in treatment tank 2, effectively increasing the contact area between water and oxygen and ultraviolet light.

[0042] The ultraviolet (UV) sterilization lamp ring 6 at the top of the treatment tank 2 begins operation, emitting UV rays to sterilize and disinfect the passing water. The transparent protective ring shell 61 effectively protects the UV sterilization lamp ring 6 from water erosion while ensuring that the UV rays can penetrate smoothly and thoroughly sterilize the water. The umbrella-shaped water-blocking shell 72 located above the oxygen outlet ring 7 prevents the water from directly impacting the oxygen outlet ring 7, ensuring that oxygen is dissolved in the water as it is discharged. After oxygenation and sterilization, the water finally flows out from the outlet at the bottom of the treatment tank 2 and is discharged back to the aquaculture area through the drain pipe 8.

[0043] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
