Product Description

Product Description

 

In the complex realms of municipal, chemical, and paper industry water treatment processes, the art of water mixing ascends as one of the paramount operations. Traditional mixing machinery, commonly categorized into vertical shaft folding paddle types and horizontal (submersible) types, inherently influences the energy consumption and the end result of the mixing process due to their paddle designs and installation methods. These conventional approaches often lead to increased operational costs for sewage plants, directly impacting the efficacy of the final treatment outcomes. Acknowledging these challenges, our dedicated years of experimentation, coupled with invaluable insights from industry peers, have culminated in the development of a revolutionary curved surface mixer. This groundbreaking innovation has been rigorously tested and successfully implemented in numerous sewage treatment plants, consistently delivering exceptional results.
 

Scope of application

 

Introducing the GSJ/QSJ series vertical circulation multi-curved surface mixer, an epitome of versatility and efficiency. This advanced mixer finds its applications in the domains of environmental protection, chemical industry, energy, light industry, and numerous other sectors requiring liquid-solid and liquid-gas exchanges. It excels particularly in the sewage treatment processes, including coagulation tanks, regulating tanks, anaerobic tanks, aeration tanks, nitrification and denitrification tanks, and in scenarios involving abrasive and high-temperature media mixing and blending.
 

Construction

 

The hyperbolic mixer is expertly categorized into the GSJ type (dry type) and the QSJ type (submersible type) based on their installation methodologies.
The GSJ type multi-curved mixer boasts a robust structure comprising a gear motor, shock-absorbing seat, mixing shaft, hyperbolic impeller, electric control box, and bridge (user-provided). Conversely, the QSJ type hyperbolic mixer features a frame, lifting rope, main machine, hyperbolic impeller, and electric control box, delivering unparalleled performance.
 

Working Principle

 

The G/QSJ series vertical circulating multi-curved mixer operates on an ingeniously designed principle. The upper surface of its curved impeller body exhibits a hyperbolic structure, formed by the rotation of a hyperbolic bus around the impeller body's axis. This unique impeller design seamlessly integrates fluid dynamics with mechanical motion. The hyperbolic equation, xy=b, rotated along the y-axis, forms this curved surface body. To optimize water flow, the impeller's central inlet design minimizes turbulence while ensuring uniform liquid pressure across the impeller surface. This balance is critical for maintaining operational stability. The eight evenly distributed guide vanes on the involute double curved surface, combined with liquid weight pressure and the centrifugal force generated by impeller rotation, drive the liquid in a tangential movement along the circumference. This process, complemented by the pool wall's reflective effect, creates a top-down water circulation, achieving cross-flow in both axial (y) and radial (x) directions, resulting in superior mixing efficiency.
The distinctive structural features of the G/QSJ series vertical circulation multi-curved mixer, especially its near-bottom pool installation, play a crucial role in preventing suspended matter from settling. This strategic positioning ensures optimal mixing performance, effectively eliminating dead zones and achieving a high degree of water exchange due to the larger specific surface area.
 

Working Characteristics

 

Our Multi Hyperbolic Mixer, a pinnacle of high-efficiency mixing technology, is adept at blending various low-viscosity liquids, solid-liquid mixtures, and gas-liquid combinations. It is versatile, seamlessly integrating into round, square, and even rectangular pools with sub-unit arrangements.
In contemporary China's sewage treatment processes, the wave mixer emerges as a solution to traditional blade (slurry) type mixers' limitations, notably prone to creating dead ends and poor water-gas mixing during aeration. The wave mixer stands out by ensuring uniform and thorough mixing, thereby enhancing the overall effectiveness of the treatment process. Key features include:
(1) Versatile in its application, this agitator can be utilized for various liquid, solid, and gas mixing scenarios. It offers a superior alternative to current mixing equipment by achieving three-dimensional, spiral mixing. This results in more uniform mixing and significantly boosts efficiency.
(2) Featuring a larger specific surface area impeller and a motor with small power requirements, it provides superior circulation water flow while maintaining low energy consumption, making it both effective and energy-efficient.
(3) The entire machine boasts a compact structure, ensuring reliable operation. It is also designed for easy installation and maintenance, promising a hassle-free experience.
(4) Constructed with reinforced fiber or steel material, the impeller adapts to diverse working conditions and guarantees a long service life, providing both durability and versatility.

Sizing Applications

 

The selection process for multi-curved mixers mirrors that of other mixers, with installation method being the sole distinguishing factor. Key parameters such as the type of pool, volume, liquid depth, medium concentration, temperature, and pH levels all play a critical role in the selection process.
Selection of curved mixers primarily hinges on determining the effective service area of each device. For rectangular pools, the length-to-width ratio should not exceed two times, allowing the pool to be divided into equal work units to ascertain the number of mixers required.
For pools exceeding 5 meters in depth or those with higher than specified concentration, it is crucial to consider increasing the power or operational speed of the mixer to ensure effective mixing in large capacity and high concentration media scenarios.
Under standard operating conditions, dry installation is recommended. For environments with noise or visual constraints, submersible installation is more suitable. Our company is available to assist users in selecting the best option for special environments.

Installation

 

GSJ Series Installation Steps
1. Ensure the bridge is corrected horizontally and the half bridge column is corrected vertically. All ground bolts and connecting parts should be solid and reliable.
2. Place the shock absorber seat flatly on the specified position of the bridge and secure it after leveling.
3. Mount the gearbox motor on the shock absorber seat and secure it properly.
4. Bolt the impeller to the flange of the mixing shaft and ensure it is fastened securely.
5. Insert the impeller and mixing shaft into the pool, then connect the mixing shaft with the output shaft of the reducer and fasten it. If submerged, connect the shaft and impeller underwater first, then link the shaft to the reducer.
6. After installation, the mixing shaft should be perpendicular to the horizontal plane with a vertical deviation of less than 1/1000.
7. Post-installation, remove the motor tail cover and manually rotate the fan blade to check for smooth and normal operation. The swing deviation of the mixing shaft should be less than 3/1000.
8. Upon connecting the power supply, briefly engage the mixer and observe the mixing shaft's direction. The correct direction is counterclockwise from top to bottom. If incorrect, adjust 2 power wiring positions.
9. The installation of electrical equipment must comply with relevant national and safety regulations.

QSJ Series Installation Steps
1. Initially, observe the impeller transfer direction from the shore. The correct direction is counterclockwise from top to bottom. If the direction is incorrect, switch 2 power wiring positions accordingly.
2, Ensure the motor cable and sling are separately fixed, never bundling the cable and steel rope together. This prevents the steel rope and cable from getting entangled in the impeller.
3, Utilize a crane to gently lift the hyperbolic surface and slowly lower it into the pool to the designated position. Be cautious not to hit the pool wall.
4, Secure one end of the fixed rope to the bank, and connect the cable to the electric control cabinet for efficient operation.
