Description

Technical Field

[0001] This utility model relates to the technical field, and in particular to a structure for an efficient and energy-saving aerator that is easy to install. Background Technology

[0002] Aerators are commonly used in aquaculture and landscape water features. Their main function is to increase the dissolved oxygen content in the water to meet the survival and growth needs of aquatic organisms. Currently, there are many types of aerators on the market, but they all generally have some problems.

[0003] However, the installation process of existing aerators is quite cumbersome, requiring specialized tools and personnel, and the installation time is long. In some large aquaculture ponds, multiple aerators need to be installed, and the cumbersome installation process will greatly increase the labor intensity and cost of users. Existing aerators have high energy consumption, their oxygenation efficiency is not ideal, and the structural design of the aerator is not reasonable enough, resulting in a small contact area between oxygen and water and low dissolution efficiency, which affects the oxygenation effect and increases operating costs. Therefore, we propose an easy-to-install, high-efficiency and energy-saving aerator structure. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this utility model provides an easy-to-install, high-efficiency, and energy-saving aerator structure. The arc-shaped float is installed in the cavity between the circular protective cover and the inner support sleeve, saving space and providing stable support that is not prone to tipping over. The arc-shaped float automatically adapts to the water level, making the aerator easy to install. Personnel only need to place the aerator in the corresponding position in the aquaculture area and connect the power supply to complete the installation, greatly reducing the labor intensity of users. By installing the conical base at the center of the bottom end of the inner support sleeve, it effectively prevents the spiral impeller from sinking into silt and sand due to excessively low water levels in the aquaculture area. The structural design is relatively reasonable, increasing the practicality of the aerator.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a high-efficiency and energy-saving aerator structure that is easy to install, including a floating device, a driving device, and an installation assembly. The driving device adopts a variable frequency drive motor, and a spiral impeller is installed at the bottom end of the drive shaft of the variable frequency drive motor. The floating device adopts three arc-shaped floats. The installation assembly includes a circular protective cover, a conical guide cover, a conical base, a triangular support frame, and an inner support sleeve. The bottom end of the variable frequency drive motor is fixed to the top end of the conical guide cover by bolts. A circular protective cover is fixedly installed on the outer side of the bottom end of the conical guide cover. An inner support sleeve is fixedly welded to the inner side of the circular protective cover. A water spray channel is provided between the support sleeve and the conical guide shroud. A water outlet is opened on the top surface of the inner support sleeve. A triangular support frame is welded to the bottom of the circular protective cover and the inner support sleeve. Connecting pieces are fixedly provided on both sides of the arc-shaped float. The connecting pieces are installed on the surface of the triangular support frame by fixing bolts. The arc-shaped float is located between the circular protective cover and the inner support sleeve. An installation ring is fixedly provided at the center of the triangular support frame. A conical base is installed at the bottom of the installation ring by locking bolts. A connecting hole is opened on the top surface of the conical base. The connecting hole communicates with the water outlet. The spiral impeller at the bottom of the variable frequency drive motor is located inside the inner support sleeve.

[0006] As a preferred embodiment of this utility model, an arc-shaped filter screen is installed on the inner side of the bottom end of the inner support sleeve, and a central filter screen is installed on the inner wall of the bottom end of the conical base.

[0007] As a preferred embodiment of this utility model, a hanging ring is fixedly provided on the outer surface of the circular protective cover.

[0008] As a preferred embodiment of this utility model, the variable frequency drive motor is a permanent magnet variable frequency synchronous motor, and a protective top cover is installed on the top of the variable frequency drive motor.

[0009] As a preferred embodiment of this utility model, the bottom end of the arc-shaped float is provided with a sealing air nozzle, and the arc-shaped float is made of high-density polyethylene material.

[0010] As a preferred technical solution of this utility model, the spiral impeller is made of stainless steel, and the spiral impeller is provided with a number of inclined blades, and the surface of the blades is provided with a number of small protrusions.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. The arc-shaped float is installed in the cavity between the circular protective cover and the inner support sleeve, saving space and providing stable support that is not easy to tip over. The arc-shaped float automatically adapts to the water level, making the aerator easy to install. Personnel only need to place the aerator in the corresponding position in the aquaculture area and connect the power supply to complete the installation, which greatly reduces the labor intensity of users. By installing the conical base at the center of the bottom end of the inner support sleeve, it effectively avoids the spiral impeller from sinking into the silt and sand due to the low water level in the aquaculture area. The structural design is relatively reasonable, increasing the practicality of the aerator.

[0012] 2. By using a conical guide shroud and a spiral impeller, the water spray range is wider, the contact area between water and oxygen is increased, and the dissolution efficiency is higher, thereby improving the oxygenation effect and reducing operating costs. The use of an arc-shaped filter and a central filter prevents the spiral impeller from damaging aquatic organisms during the operation of the aerator. Attached Figure Description

The arc-shaped float 9 is located between the circular protective cover 3 and the inner support sleeve 10. An installation ring is fixedly installed at the center of the corner support frame 8. A conical base 6 is installed at the bottom of the installation ring by locking bolts. A connecting hole 14 is opened on the top surface of the conical base 6, which is connected to the water outlet 15.
