The characteristics of the hyperbolic mixer and its differences from other mixing equipment

Characteristics of hyperbolic mixer (vertical mixer):
The hyperbolic mixer (vertical mixer) has changed the disadvantages of conventional mixers such as uneven flow velocity, dead corners, and low volume utilization in the mixing tank. It produces uniform bottom omnidirectional push flow in the tank, without sedimentation, and the water surface is calm, with no air entering the water; The appearance of the mixing impeller is reasonable, with a double curved surface design and a non blade structure. It will not produce any debris or fiber entanglement on the mixer, so no maintenance is required during normal operation.
The hyperbolic mixer (vertical mixer) has low impeller speed, low wear, good corrosion resistance, reliable performance, and long service life. Compared with conventional mixers, this high-capacity omnidirectional push flow hyperbolic mixer has lower energy consumption. It generally only requires 2-3 watts to stir 1 cubic meter of sewage, with energy savings of 30% to 50%.

The difference between a hyperbolic mixer (vertical mixer) and other mixing equipment is that:
1. Due to the ideal fluid conditions, energy consumption is lower.
2. Due to the high flow rate of water in the entire pool, there will be no sludge sedimentation.
3. The mixer can self correct during operation, ensuring that the downward force is vertical and preventing unbalanced movement.
4. Omnidirectional flow, all areas in the pool can be evenly stirred without creating blind spots.
5. There are no vulnerable parts underwater, and it is easy and convenient to reach the deceleration motor for maintenance.
6. Do not use materials that are prone to rusting, and use advanced corrosion-resistant materials for both the mixing disc and mixing shaft.
7. Overall exquisite. Continuous improvement ensures an extremely long service life and sturdy and durable quality.
8. It won't block. Unlike horizontal flow mixers, there will be no substance attached to the mixing body.

Spiral reflux hyperbolic mixer low-priced supplyPerformance and structural specifications:

The hyperbolic mixer is suitable for operation in sewage or sludge. During operation, no fibers should be attached to any part underwater to ensure uniform mixing in each area of the tank and no sludge sedimentation in the entire tank.

The hyperbolic mixer can operate continuously 24 hours a day, with a designed service life of not less than 20 years. It needs to operate continuously under full immersion conditions, running smoothly and without vibration throughout the entire operation process, with a running time of at least 10000 hours.

The shaft power of the mixer should ensure water mixing, with an average flow velocity at the bottom of the pool of ≥ 300mm/s. The motor power should be greater than 1.15 times the actual shaft power, and the mixer should not be overloaded under design conditions.

The entire weight of the hyperbolic mixer should be supported on the concrete floor, and the position of the impeller should be close to the bottom of the pool. There should be no bearing support at the bottom. The main drive shaft of the mixer should be designed as a whole and directly connected to the reducer, and cannot be a segmented structure connected by a coupling. Connected to the gear reduction motor through a cantilevered vertical shaft, and the gear reduction motor transmits torque.

The turbine impeller should be in the form of a conical hyperboloid, semi open, and with guide ribs on the conical surface. The connection between the impeller and the shaft must be made using countersunk nuts, and other methods are not accepted.

The rotation direction of the impeller of the hyperbolic mixer is determined according to the actual flow state of the wastewater in the process, and can be viewed as clockwise or counterclockwise rotation.

The motor reducer and installation base are fixed on the concrete floor. The motor design complies with IEC standards, F-class insulation, power supply 380V, 3-phase, 50HZ, protection level IP65, and can be started at least 12 times per hour.

The reducer is directly connected to the motor. The reducer adopts a helical gear reducer, and the gear design should comply with DIN standards. The gear material is alloy steel, with a hard tooth surface, a service factor of ≥ 2.0, and a rated bearing life of ≥ (L10) 100000 hours.

Hyperbolic mixer anti-corrosion

All materials of the hyperbolic mixer manufactured by Jiangsu Du'an Environmental Protection are suitable for the corrosive environment of sewage treatment plants. Unprotected or non anti-corrosion materials should be treated according to the provisions of general technical requirements.

The hyperbolic mixer is composed of a driving device, a hyperbolic impeller body, and installation accessories. In order to meet the needs of users under different working conditions, the installation is divided into two types: dry (also known as vertical shaft) and submersible. Dry installation, fixing the driving device on the working bridge and transmitting kinetic energy to the impeller components in the medium through the transmission shaft. It is used in liquids with high solid content, high water temperature, and abrasive properties. Due to the automatic correction function of the impeller, it runs smoothly and the noise of the reducer is less than 60 decibels. Submersible installation, eliminating the need for cable trays, using submersible power, utilizing equipment self weight positioning, flexible and convenient installation, suitable for deep water, stable water quality, non abrasive water bodies, water temperature not exceeding 40 ℃, pH value between 6-9, characterized by no noise and no visual barriers.

Inspection and testing of hyperbolic mixer

Before leaving the factory, the equipment should undergo factory inspection and testing, and provide a product qualification certificate or quality certificate.

After installation, it should be inspected as required to ensure that its performance meets the specified indicators.

The mixer should run smoothly and without any jamming or shaking when running in idle mode without water.

On site load testing should be conducted, and 24-hour loaded operation should be carried out under design conditions, with the operating current not exceeding the rated current of the motor. Measure the uniformity of the mixer to ensure it meets the design requirements.
