Product Description

Product Description

In the intricate world of municipal, chemical, and paper industry water treatment, mastering the art of water mixing emerges as a key operation. Traditional mixing machinery, often classified into vertical shaft folding paddle types and horizontal (submersible) types, profoundly affects both energy consumption and the quality of the mixing process due to their paddle designs and installation methods. However, these conventional systems frequently escalate operational expenses for sewage plants, adversely impacting the effectiveness of the final treatment outcomes. Recognizing these challenges, we have leveraged our extensive years of experimentation, alongside invaluable insights from industry experts, to create a revolutionary curved surface mixer. This groundbreaking innovation has been meticulously tested and successfully deployed across multiple sewage treatment facilities, consistently delivering outstanding results and setting new standards in wastewater treatment efficiency.

Scope of application

Introducing the GSJ/QSJ series vertical circulation multi-curved surface mixer, an unparalleled manifestation of versatility and efficiency. This state-of-the-art mixer seamlessly integrates into the realms of environmental protection, chemical industry, energy, light industry, and an extensive array of other sectors demanding precise liquid-solid and liquid-gas exchanges. Its exemplary performance is particularly highlighted in sewage treatment processes, such as coagulation tanks, regulating tanks, anaerobic tanks, aeration tanks, nitrification and denitrification tanks. Moreover, it shines in situations involving the mixing and blending of abrasive and high-temperature media, making it an essential tool for superior performance and reliability in complex industrial scenarios.

Construction

The hyperbolic mixer is meticulously organized into two distinct classifications: the GSJ type (dry type) and the QSJ type (submersible type). These categorizations are determined by their specific installation techniques, ensuring optimal functionality and adaptability for various applications.
The GSJ type multi-curved mixer showcases an impressively durable design, which includes a gear motor, shock-absorbing seat, mixing shaft, hyperbolic impeller, electric control box, and a user-supplied bridge. On the other hand, the QSJ type hyperbolic mixer is equipped with a sturdy frame, lifting rope, main machine, hyperbolic impeller, and an electric control box, all working in harmony to provide unmatched performance efficiency.

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 true marvel of advanced mixing technology, excels in seamlessly blending a variety of low-viscosity liquids, solid-liquid mixtures, and gas-liquid combinations. Its versatility is unmatched, effortlessly integrating into round, square, and even rectangular pools with innovative sub-unit arrangements, making it the ideal choice for diverse applications.
In the realm of modern China's wastewater treatment, the wave mixer emerges as a groundbreaking solution, addressing the limitations seen in traditional blade (slurry) type mixers. These older models often struggled with issues like creating dead zones and poor water-gas mixing during aeration. The wave mixer revolutionizes this process by ensuring comprehensive and uniform mixing, thereby vastly enhancing the effectiveness of the treatment process. Its standout features include:
(1) The unmatched versatility of this agitator allows for its use across various liquid, solid, and gas mixing scenarios. It represents a superior upgrade over conventional mixing equipment by achieving three-dimensional, spiral mixing, resulting in exceptionally uniform mixing and substantial efficiency improvements.
(2) With its larger specific surface area impeller and low power requirement motor, it provides exceptional circulation water flow yet maintains low energy consumption. This design makes it a paragon of both efficacy and energy efficiency.
(3) The machine's compact structure ensures reliable operation while being engineered for straightforward installation and maintenance, promising users a seamless and trouble-free experience.
(4) Crafted using reinforced fiber or steel materials, the impeller is adept at adapting to a variety of working conditions, guaranteeing a long service life with unparalleled durability and versatility.

Sizing Applications

The meticulous selection process for our advanced multi-curved mixers is akin to that of traditional mixers, with the installation method being the unique differentiator. Essential parameters, such as pool type, volume, liquid depth, medium concentration, temperature, and pH levels, are pivotal in guiding the selection to ensure optimal performance and efficiency.
The selection of our sophisticated curved mixers is predominately based on identifying the effective service area of each unit. Specifically for rectangular pools, the ideal length-to-width ratio should not surpass twice the width, allowing for an effective division into equal work units, precisely determining the requisite number of mixers needed for optimal operation.
In scenarios where pools extend beyond a depth of 5 meters or contain concentrations exceeding standard specifications, it becomes imperative to consider augmenting the mixer's power or operational speed. This strategic adjustment ensures efficient mixing, even in large capacity and high concentration media settings, enhancing overall system performance.
Under typical operational environments, a dry installation is preferable. However, in settings where noise reduction or visual integration is critical, a submersible installation becomes the optimal choice. Our expert team stands ready to aid users in selecting the most suitable installation option tailored to unique environmental conditions.
