Lanjiang nitrification tank frame mixer/device

1Product Introduction:

The connection method between the JBK frame mixer and the mixing shaft is similar to that of a paddle type mixer, where one end of the impeller is connected to the mixing shaft to form a semi-circular collar, and then the two semi-circular rings of the two sides of the blades are clamped on the mixing shaft with bolts, while the blades and the mixing shaft are fixed with through shaft bolts.

Due to the large external dimensions of the impeller, most of the blades are connected by bolts for ease of assembly and disassembly. The impeller is mostly made of flat steel and angle steel. In order to improve the strength of the impeller, reinforced steel plates can also be used.

IIConstruction and working process:

IIIfeature:

1. Simple construction, reliable operation, no blockage, and easy maintenance.

2. It can meet the requirements of flocculation laws, so that each section has different stirring intensities during the flocculation process, and can adapt to changes in water volume and temperature. Small head loss, simple pool structure, and convenient combination of external energy.
3. After setting the stepless speed regulation, the stirring intensity can be adjusted according to changes in water volume, raw water turbidity, and dosage, achieving satisfactory flocculation effect and saving the amount of chemicals used.

The JBK frame mixer consists of a motor, reducer, frame, mixing shaft, paddle board, coupling, underwater support, etc.

Frame structure mixerCADimageAs shown in the figure, it consists of a mixing shaft, a frame type mixing blade, a bearing device, a machine base, and a driving device.

When the mixed liquid of raw water and coagulant or coagulant aid flows through the sedimentation tank, flow circulation is generated under the discharge effect of the mixer, causing the colloidal particles in the water to collide, adsorb and gradually form alum flowers of different sizes, resulting in the majority of alum flowers being trapped in the sedimentation tank.

4Application fields:

Blenders typically operate at low speeds and do not generate significant shear forces when stirring low viscosity liquids, making them unsuitable for liquid-liquid and gas-liquid dispersion. On the other hand, this type of impeller moves at a high flow rate inside the tank, with horizontal swirling flow dominating and lacking good mixing uniformity. However, the flow velocity near the tank wall can achieve a higher heat transfer film coefficient than other impellers, making it commonly used for heat transfer and crystallization operations.

In addition, due to the large diameter of the blade and its proximity to the bottom of the tank, it is also commonly used to stir high concentration slurries and precipitating slurries. It is also commonly used for stirring high viscosity fluids.
