Hyperboloid Mixer

Hyperbolic mixer is a kind of mixing equipment, which is widely used in liquid stirring and mixing in the fields of municipal, chemical, food, pharmaceutical, etc. Its core component is the impeller with hyperbolic design. The guide vanes on the impeller discharge the liquid along the tangent line of the impeller circumference. Under the reflection of the pool wall, a circulating water flow from top to bottom is formed, realizing axial and radial cross flow, which can effectively prevent the sedimentation of suspended matter, eliminate the dead angle of stirring, and ensure the uniformity of stirring.

Low Energy Consumption
The power consumption of a hyperboloid mixer is 8-10 watts per cubic meter, while the power of traditional mixing equipment is usually as high as 15-20 watts/cubic meter. Taking a sewage treatment tank with a capacity of 1,000 cubic meters as an example, using a hyperboloid mixer can save approximately 10,000 kilowatt hours of energy consumption per year, which is equivalent to reducing 8 tons of carbon dioxide emissions.

Uniform Mixing Effect
The unique impeller design of the hyperboloid mixer can form a three-dimensional flow field in the pool, that is, the liquid flows in the pool in three directions: up and down, front and back, and left and right, instead of just rotating in a single plane. Through this three-dimensional flow field, the mixer can circulate liquid at a flow rate of 0.3-0.6 meters/second. When processing mixtures with a solid content of up to 5%, the mixing uniformity can reach more than 98%, which is significantly superior. About 90% of the traditional mixer.

Low Noise Operation
The hyperboloid mixer's low-speed operating design (typically 40-120 rpm) greatly reduces noise levels. Its operating noise is usually less than 60 decibels, while the noise of ordinary high-speed mixers can be as high as 75 decibels. The low noise characteristics make it particularly suitable for places with strict environmental noise requirements such as urban sewage treatment plants and food production workshops.

The hyperboloid impeller is formed by rotating a curve along the Y-axis, creating a surface that facilitates fluid flow. To accommodate water movement, the impeller is designed to intake water from the center. This design reduces inlet flow and ensures uniform pressure on the impeller surface, maintaining balance during operation. The impeller features eight evenly distributed guide vanes on the gradually curved double arc surface. The potential energy gained from the water's own weight, combined with the centrifugal force generated by the rotating impeller, creates kinetic energy. Under the influence of gravitational acceleration, the fluid moves tangentially along the impeller's circumference. This movement, coupled with the reflection from the tank walls, forms a circulation flow from bottom to top, resulting in crossflows in both the axial (Y) and radial (X) directions.
The structural characteristics of the hyperboloid mixer impeller and its near-bottom installation enable it to achieve ideal mixing effects, effectively eliminating dead zones.

The above mixer parameters are obtained under the test of voltage of 380V and frequency of 50Hz.

The hyperbolic mixer is composed of drive parts, impeller, base, hoisting system and electronic control.

Submersible Installation
