Product Introduction

　　Preface:

In chemical, papermaking, and various other water treatment processes, water stirring and mixing is one of the key process steps. Traditional stirring equipment is typically categorized into two common types: vertical propeller and horizontal (submersible) designs. Due to the installation method and blade shape, these determine the stirring pattern, which is not ideal in terms of energy consumption and mixing efficiency. This not only unnecessarily increases the operational costs of wastewater treatment plants but also directly impacts the effectiveness of the treatment process. To address these issues, after years of testing and leveraging the design experience of industry peers, a new curved stirrer has been developed. After many years of practical application in multiple wastewater treatment plants, it has achieved favorable results.

　Application Scope:

The G/QSJ series curved agitator is one of our mixers. It is widely used in industries such as environmental protection, chemicals, energy, and light industry where liquid mixing with solid-liquid, gas, and liquid-liquid is required, particularly suitable for sedimentation tanks, regulation tanks, anaerobic tanks, nitrification, and denitrification tanks in wastewater treatment processes.

Operating Principle:

The G/QSJ series curved impeller mixers feature a double hyperbolic paraboloid structure on the surface of the curved impeller body, formed by the rotation of the hyperbola's generatrix around the impeller body's axis. This design optimally combines fluid characteristics with mechanical motion. The equation of the hyperbola is xy=b, and the curve rotating along the y-axis forms the curved body. To accommodate water flow, the design incorporates water intake from the center of the impeller, which reduces the intake turbulence and ensures uniform pressure on the impeller surface, thereby maintaining the overall balance of the machine during operation. There are eight guide vanes evenly distributed on the involute double arcs, which, with the help of the potential energy obtained from the additional water intake due to the liquid's own weight pressure, form kinetic energy along with the centrifugal force generated by the impeller's rotation. Under the influence of gravity, the liquid moves tangentially along the circular path of the impeller due to the transition through the double hyperbolic paraboloid structure. With the reflection from the pool wall, a cyclic water flow is formed from top to bottom, thus enabling cross flows in both the axial (y) and radial (x) directions (as shown in the double hyperbolic flow state diagram).

The structural characteristics of the impeller and the feature of being installed close to the bottom of the pool in the G/QSJ series curved blade mixers directly determine their sediment prevention effect on suspended particles. During operation, they achieve ideal mixing results and effectively eliminate dead mixing zones. The larger specific surface area allows for extensive water exchange over a wide area.

　Structural Overview:

The G/QSJ series curved impeller mixers consist of a drive unit, a double curved impeller body, and installation accessories. To meet the varying operational conditions of users, the installation is available in two types: dry (also known as vertical shaft) and submersible. The dry installation involves fixing the drive unit to a work bridge and transferring kinetic energy to the impeller components in the medium through a transmission shaft. It is suitable for liquids with high solid content, high water temperature, and abrasive properties. Thanks to the automatic alignment feature of the impeller, the operation is relatively smooth, with the reducer noise below 60 decibels. The submersible installation eliminates the need for bridge structures, utilizes submersible power, and is positioned by the equipment's own weight, offering flexible and convenient installation. It is suitable for deep water bodies with stable water quality, free of abrasive properties, with water temperature not exceeding 40°C, and a pH value between 6 and 9. Its key features include noiselessness and no visual obstructions.

　　Job Characteristics:

The G/QSJ series curved blade mixers, as a mixing equipment, are suitable for blending and mixing various low-viscosity liquids, as well as for solid-liquid and gas-liquid mixtures; they are not only applicable to circular and square pools but are also commonly used for unit arrangement in rectangular water pools.

In our country's existing wastewater treatment processes, the propeller mixer primarily overcomes the issue of dead spots that commonly occur in traditional blade (propeller) mixers, as well as the poor water-aeration mixing effect in the aeration process, by leveraging its even mixing advantage. Its main features are as follows:

(1) Suitable for various liquid and solid, gas mixing applications, it can replace existing mixing equipment, achieving three-dimensional spiral mixing for more even and efficient stirring.

(2) Larger specific surface area impeller, with less power, larger circulation water flow, low energy consumption; up to 30%-50% more energy-efficient than traditional stirring methods.

(3) The complete machine is compact in structure, reliable in operation, and easy to install and maintain.

(4) The impeller is made of reinforced fiber or steel material, capable of accommodating various operating conditions and boasting a long service life.

　　Selection and Application:

The G/QSJ series of curved impeller mixers have identical selection options; the only difference is the installation method. Like the selection for other types of mixers, the selection of curved impeller mixers is related to parameters such as the pool type, volume, liquid depth, medium concentration, temperature, and pH level.

The selection of the curved agitator is primarily based on the effective service area of each unit, and in accordance with the principle that the ratio of pool length to width does not exceed twice, the rectangular pool can be divided into several equal work units, thereby determining the number of agitators required.

For depths exceeding 5 meters or concentrations over the specified limit, when selecting a model, consider increasing the power or the working speed of the agitator to ensure effective mixing in large-volume and high-concentration media.

Under normal operating conditions, it is recommended to prioritize dry installation; for noise or visual requirements, submersible installation is suggested. Our company can assist customers in selecting the appropriate type for special environments.

　　Installation:

The installation of the curved mixer comes in two types: dry installation and wet installation, both of which are extremely simple.

The wet-mounted mixer can be directly hoisted into position using a crane or hoist, relying on its own weight for alignment, and the cables are securely fastened. See the wet-mounted installation diagram.

The dry-mounted mixer first secures the reducer frame onto the work bridge, followed by the sequential installation of the drive shaft, impeller components, and the cable, as shown in the dry-mounted installation diagram.

　　Cautionary Notes:

1. Prior to installation, a qualified electrician must inspect the motor and electrical equipment, and confirm the direction. The working distance of the impeller from the bottom of the pool should be ≤300mm, and the pool bottom must be flat, solid, and free of construction debris.

2. Ensure against impeding and causing impeller blockage, which may damage the motor, when restarting equipment that has been idle for an extended period.

3. Consider the impeller's inlet and outlet dimensions within a closed basin.

4. Regardless of the installation method, ensure the underwater cable is securely fastened to prevent wear.

5. Carefully read the product installation and usage manual before use.
