Description

Technical Field

[0001] This utility model relates to the field of anti-corrosion and oxygenation technology for aquaculture, specifically to an anti-corrosion and oxygenation device for crucian carp farming in saline-alkali water areas. Background Technology

[0002] Saline-alkali areas are larger regions compared to saline-alkali land, consisting of vast areas of saline-alkali soil, referring to areas formed by the accumulation of easily soluble salts in the topsoil. They are classified into three levels based on salinity: mild (0.1%-0.3%), moderate (0.3%-0.6%), and severe (>0.6%). Salt content directly affects the normal growth of crops. In existing crucian carp farming in saline-alkali water areas, aerators are typically used to effectively desorb harmful gases already present in the water, such as hydrogen sulfide, ammonia, methane, and sulfur dioxide, and release them into the air. This also effectively desorbs harmful gases from the water and improves oxygenation. However, the existing technology has the following problems: During use, existing aerators are prone to malfunction because debris in the water adheres to the aerator body as the impeller rotates. They are also susceptible to corrosion from saline and alkaline water. Furthermore, relying solely on aerators to oxygenate the surface layer of the water cannot improve the oxygen deficiency problem at the bottom. Utility Model Content

Several threaded holes are arranged in a circular array on the lower side of the outer wall of the mounting base.

[0006] A further improvement of this utility model is that the waterproof motor, mounting base, impeller and support rod are all made of stainless steel, and the outer surface of the float is coated with an anti-corrosion coating.

[0007] A further improvement of this utility model is that the protective component includes a protective cylinder, a mounting sleeve, several bolts, a rotating rod, an L-shaped bracket, and a U-shaped scraper. The bottom of the mounting sleeve is fixedly connected to the top of the protective cylinder. The outer wall and bottom of the protective cylinder are respectively provided with several through holes arranged in a ring. The outer wall of the mounting sleeve is provided with insertion holes that are adapted to the threaded holes. The L-shaped bracket is arranged outside the protective cylinder. The inner wall of the L-shaped bracket is fixedly connected to the outer wall of the U-shaped scraper. The bottom of the outer wall of the rotating rod extends through to the central axis of the bottom of the protective cylinder and is fixedly connected to the upper surface of the U-shaped scraper.

[0009] A further improvement of this utility model is that: several toothed blocks are fixedly connected in an equidistant array on both sides of the inner wall of the U-shaped scraper near the rotating rod, and one end of the toothed blocks overlaps the outer wall of the protective cylinder.

[0010] A further improvement of this utility model is that the underwater oxygen supply mechanism includes an ejector, a delivery pipe, a connecting pipe, several branch pipes, and several nozzles. The output pipe of the ejector is fixedly connected to one end of the delivery pipe, and the other end of the delivery pipe is fixedly connected to the outer wall of the connecting pipe.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a corrosion-resistant aeration device for crucian carp farming in saline-alkali water areas. It utilizes the cooperation between an aerator and a protective component. By making the casings of both the aerator and the protective component stainless steel, it effectively resists acid and alkali corrosion. The protective component is threaded onto the outside of the impeller, and the rotation of the impeller drives a U-shaped scraper to remove impurities adhering to the outside of the protective casing. This solves the problem of existing aerators being prone to malfunction due to impurities in the water adhering to the aerator body as the impeller rotates, and is also susceptible to corrosion from saline-alkali water. It achieves corrosion resistance, protects the aerator, and effectively cleans adhering impurities.

[0013] 2. This utility model provides a corrosion-resistant oxygenation device for crucian carp farming in saline-alkali water areas. It adopts the cooperation between the breeding pond and the bottom oxygenation mechanism. During the breeding period, the bottom oxygenation mechanism is operated to force oxygen into the bottom of the water, which greatly increases the gas-liquid contact surface area, so that oxygen can dissolve in the water more efficiently. The turbulence formed during the rise of the bubbles further prolongs the oxygen transfer time. This solves the problem that relying solely on aerators to oxygenate the surface layer of the water cannot improve the oxygen deficiency at the bottom, and achieves the beneficial effect of improving the oxygenation efficiency at the bottom.

Through the coordinated operation of the aerator 2 and the protective component 3, the aerator 2 can work with the protective component 3 to isolate surrounding debris while it is working. The underwater oxygen supply mechanism 4 forces oxygen into the water to the bottom, greatly increasing the gas-liquid contact surface area, allowing oxygen to dissolve in the water more efficiently. The rising bubbles form turbulence, further extending the oxygen transfer time and providing oxygen to the bottom of the water.

[0017] like Figure 2 As shown, this utility model provides a technical solution for an anti-corrosion oxygenation device for crucian carp farming in saline-alkali water areas: the aerator 2 includes a waterproof motor 21, a mounting base 22, an impeller 23, several support rods 24, several connecting blocks 25, and several floats 26.

The stainless steel body and the anti-corrosion coating can effectively increase the service life of the aerator 2 in saline-alkali water areas and are suitable for long-term immersion in high saline-alkali water bodies.

[0018] like Figure 3As shown, this utility model provides a technical solution for an anti-corrosion oxygenation device for crucian carp farming in saline-alkali water areas: the protective component 3 includes a protective cylinder 31, an mounting sleeve 32, several bolts 33, a rotating rod 34, an L-shaped bracket 35, and a U-shaped scraper 36. The bottom of the mounting sleeve 32 is fixedly connected to the top of the protective cylinder 31. The outer wall and bottom of the protective cylinder 31 are respectively provided with several through holes 310 arranged in a ring. The outer wall of the mounting sleeve 32 is provided with insertion holes 320 that are adapted to the threaded holes 220. The L-shaped bracket 35 is set outside the protective cylinder 31. The inner wall of the L-shaped bracket 35 is fixedly connected to the outer wall of the U-shaped scraper 36. The bottom of the outer wall of the rotating rod 34 penetrates to the top of the protective cylinder 31. The protective cylinder 31 has a central axis at its bottom and is fixedly connected to the upper surface of the U-shaped scraper 36. The protective cylinder 31, mounting sleeve 32, L-shaped bracket 35, and U-shaped scraper 36 are all made of stainless steel. The surface of the bolt 33 is coated with an anti-corrosion coating. By setting the protective cylinder 31 outside the impeller 23, the U-shaped scraper 36 rotates along the outside of the protective cylinder 31, generating a vortex that separates debris in the water from the protective cylinder 31. The impeller 23 is set inside the protective cylinder 31. The inside of the mounting sleeve 32 is fitted onto the outer wall of the mounting base 22. The upper end of the rotating rod 34 is fixedly connected to the bottom of the impeller 23. The outer wall of the bolt 33 passes through the insertion hole 320 and is threadedly connected to the inner wall of the threaded hole 220.

[0019] like Figure 4 As shown, this utility model provides a technical solution for an anti-corrosion oxygenation device for crucian carp farming in saline-alkali water areas: several toothed blocks 361 are fixedly connected in an equidistant array on both sides of the inner wall of the U-shaped scraper 36 near the rotating rod 34.

[0020] like Figure 5 As shown, this utility model provides a technical solution for an anti-corrosion oxygenation device for crucian carp farming in saline-alkali water areas: the underwater oxygen supply mechanism 4 includes an ejector 41, a conveying pipe 42, a connecting pipe 43, several branch pipes 44, and several nozzles 45. The output pipe of the ejector 41 is fixedly connected to one end of the conveying pipe 42, and the other end of the conveying pipe 42 is fixedly connected to the outer wall of the connecting pipe 43. One end of several branch pipes 44 is fixedly connected to the outer wall of the connecting pipe 43 at equal intervals. The connecting ends of several nozzles 45 are fixedly connected to the upper surface of several branch pipes 44 at equal intervals. The outer walls of several branch pipes 44 are all located at the bottom of the aquaculture pond 1. The outer walls of several branch pipes 44 and nozzles 45 are all coated with anti-corrosion paint. The oxygen is forcibly injected into the bottom of the water through the ejector 41, which greatly increases the gas-liquid contact surface area, making oxygen dissolve in the water more efficiently. Turbulence is formed during the rise of the bubbles, which further prolongs the oxygen transfer time.

[0021] The working principle of this corrosion-resistant oxygenation device for crucian carp farming in saline-alkali water areas will be explained in detail below.

[0022] like Figure 1-5 As shown, when farming crucian carp in saline-alkali water areas, firstly, by using bolts 33 to pass through the insertion hole 320 and fix them to the threaded hole 220, the protective cylinder 31 is fixed to the outside of the impeller 23. Then, the waterproof motor 21 is floated on the water surface through multiple floats 26 coated with anti-corrosion paint, and the impeller 23 is submerged in the water. By starting the waterproof motor 21, the impeller 23 is driven to rotate. When the impeller 23 rotates, a low-pressure zone is formed at the bottom, which draws up the oxygen-deficient water from the bottom and pushes it to the surroundings, forming a water curtain and waves, increasing the water-air contact area. The rear of the impeller 23 blades generates negative pressure, which draws in air and breaks it into microbubbles. After entering the pressure zone of the impeller 23, the oxygen dissolution is accelerated. The microbubbles diffuse with the water flow, prolonging the gas-liquid contact time. At the same time, the impeller 23 continuously stirs and agitates the water. The impeller 23 breaks down water stratification and promotes uniform dissolved oxygen. During this process, the U-shaped scraper 36 rotates outside the protective cylinder 31 via the rotating rod 34, effectively separating the water flow from surrounding debris. Combined with the toothed block 361, it can scrape off impurities attached to the surface of the connecting hole 310. Then, by connecting the jet injector 41 to the power supply, oxygen in the air is diverted through the connecting pipe 43 to the branch pipe 44 and sprayed out from multiple nozzles 45, forcibly filling the bottom of the water with external oxygen, greatly increasing the gas-liquid contact surface area, making oxygen dissolve in the water more efficiently. The rising bubbles form turbulence, further extending the oxygen transfer time and effectively oxygenating the aquaculture pond 1, providing sufficient oxygen for crucian carp farming.

[0023] The specific types and structures used are all existing products, and the specific circuit connection structure and control relationship are all existing technologies, so they will not be elaborated on here.

[0024] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
