SQJB Hyperboloid Mixer

The SQJB hyperboloid mixer has a simple structure and is easy to install. As shown in the following figure, it consists of driving components, a base, a main shaft, an impeller, and an electric control system. The equipment is installed on a fixed base above the pool, and the stirring impeller underwater is connected through a transmission shaft made of carbon steel or stainless steel. The stirring impeller is arranged close to the ground, and by changing the length of the transmission shaft, it can adapt to pools of different depths.

Drive components 

The drive components consist of a motor, a high - quality reduction gearbox and a transmission shaft. The drive form adopts a helical gear reducer. It has low energy consumption, superior performance, low vibration and low noise. The helical gear is made of forged steel, and its surface is carburized and hardened. Through precision machining, the parallelism and positioning accuracy of the shaft are ensured, and it has a long service life. The transmission bearing is a high - quality product, ensuring stable and long - term operation. The motor is an IEC standard motor, of outdoor type, with a protection class of IP55 and an insulation class of F. 

Base 

The drive components are fixed on a base with a shock absorption device, which is used to eliminate vibrations generated during equipment operation and can correct axial forces caused by water flow. 

Main shaft 

The main shaft is a connecting part between the drive components and the impeller. It undergoes straightening and one-time forming processing to ensure excellent straightness. According to user needs, high-strength and corrosion-resistant materials such as carbon steel with heavy anti-corrosion treatment, carbon steel wrapped with FRP (Fiberglass Reinforced Plastic), and stainless steel can be used to meet rigidity and strength requirements.

Impeller 

The unique impeller structure design of the SQJB hyperboloid mixer maximizes the perfect combination of fluid characteristics and mechanical movement. The flow lines on the surface of the hyperboloid impeller are completely tangent combinations, and the entire surface is a hyperboloid formed by rotating around the center of the transmission shaft. Designed to receive water from the center of the impeller to accommodate water flow, this reduces the inflow velocity on one hand and ensures uniform pressure of the liquid on the impeller surface on the other hand, which is beneficial to water flow, reduces vibration during the operation of the whole machine, and ensures the balance of the whole machine in motion. 

Guide vanes are evenly distributed on the newly opened double arc surfaces. With the potential energy obtained from supplementary water inflow by means of the self-weight pressure of the liquid and the centrifugal force generated when the impeller rotates, kinetic energy is formed. The liquid makes a tangential movement along the circumferential direction of the impeller under the condition of gravitational acceleration, and forms a circulation flow from bottom to top under the reflection of the pool wall. It is precisely because of the structural characteristics of the impeller of the hyperboloid mixer and the feature of being installed close to the pool bottom that it can achieve an ideal mixing effect during operation, form uniform omnidirectional flow pushing, effectively eliminate mixing dead zones, and achieve ideal mixing and stirring effects.

The SQJB hyperboloid mixer overcomes the shortcomings of conventional mixers such as uneven flow velocity in the mixing tank, existence of mixing dead zones, and low volume utilization rate. It generates uniform bottom omnidirectional flow in the tank, with no dead zones, no sedimentation, and the water surface remains calm without air entering the water. The impeller has a perfect shape with a hyperboloid design and adopts a non-blade structure, which prevents any debris from being caught on the mixer and avoids fiber entanglement, so no maintenance is required during normal operation. 

The impeller features low rotation speed, low wear, and good corrosion resistance, ensuring reliable performance and a long service life. Compared with conventional mixers, this large-capacity omnidirectional flow hyperboloid mixer has lower energy consumption, generally requiring only 3-4 watts to mix 1 cubic meter of sewage, achieving an energy saving of 30%-50%.

The SQJB hyperboloid mixer is suitable for occasions in environmental protection, chemical industry, energy, light industry and other industries that require mixing and blending of liquid - liquid, liquid - solid, and liquid - gas. It is particularly suitable for mixing in sewage treatment projects and water purification projects, as follows:

1.Mixing in equalization tanks: Used in equalization tanks for adjusting peak flow and peak load in sewage treatment projects, aiming at homogeneous mixing. Typical applications are in industrial projects such as wineries, printing and dyeing factories, paper mills, etc. 

2.Mixing and coagulation mixing: Used for dissolving chemicals and coagulating mixing of chemicals with water in water treatment; that is, in occasions where the operating process requires additional chemical treatment, such as adding lime or other sewage treatment chemicals. 

3.Disinfection mixing: Used for contact mixing between liquid chlorine and other disinfectants with water in water treatment; its function is to improve the mixing degree of liquid chlorine and sewage.
