Selection of Double Surface Blender for Sludge Treatment Tank

Selection of Double Surface Blender for Sludge Treatment TankCan create large capacitywater flowThe mixing device is capable of achieving large-scale circulation and gentle water flow with minimal power.doubleDesign of impeller structure for curved mixer, relativelyMaximizing the correlation between fluid characteristics and mechanical motionphasecombination. The surface of a multi curved impeller is represented by the equationxy=bAlong the curved lineyA curved surface formed by the rotation of an axis;In order to cater to the flow of water, the design introduces water from the center of the impeller, reducing turbulent inflow and ensuring even pressure of the liquid on the surface of the impeller, thus ensuring the balance of the entire machine in motion. There are eight guide vanes evenly distributed on the gradually opening multi arc surface. The potential energy obtained by supplementing the inflow with the self weight pressure of the liquid and the centrifugal force generated by the rotation of the impeller form kinetic energy. Under the condition of neutral acceleration, the liquid first moves tangentially along the circumferential direction of the impeller, and under the reflection effect of the pool wall, it forms a top-down circulating water flow. Therefore, it is possible to obtain a flow of water in the axial direction(y)And radial(x)Cross directional water flow. It is precisely because of the structure and characteristics of the multi surface agitator impeller and its proximity to the bottom of the pool that ideal mixing effects can be achieved during operation, which can effectively eliminateAccumulation and sedimentation of silt.

Selection of Double Surface Blender for Sludge Treatment TankPerformance and Structure

a.Submersible installation of hyperbolic mixer capable of daily operation24 Continuous operation for hours,The service life is20 Year.

b.Hyperbolic surfaceThe mixer ensures that the water is thoroughly mixed and the flow rate at the bottom of the pool is ≥300mm/s(From the bottom of the pool)200mm）.

c.The vertical turbine agitator is a low-speed agitator with a speed not exceeding40rpm.

d.The entire weight of the vertical turbine agitator should be supported on the bridge, and the position of the impeller should be close to the bottom of the pool without bearing support. It is connected to the gear reduction motor through a cantilevered vertical shaft, and the gear reduction motor transmits torque.

e.The turbine impeller is in the form of a conical hyperboloid, semi open, with guide ribs on the conical surface. A locking device must be installed between the impeller and the vertical shaft to prevent loosening during rotation. The impeller can self correct during rotation, ensuring that the downward force is vertical and preventing unbalanced motion.

Rated life of turbine impeller ≥20 Year.

f.Hyperbolic surfaceThe direction of the agitator impeller is determined based on the actual flow state of the wastewater in the process, and even if it is reversed, it will not cause any adverse effects Fruit.

g.The gear reduction motor adopts Guomao, and the driving device is made in GermanySEWOr Nord, and installed and fixed on the bridge, gear material is alloy steel, hard tooth surface, service factor ≥2.0 Rated life of bearings ≥(L10)100000Hour. The motor design should comply withIECStandard: The rated power of the motor must be greater than the actual powercompareHigh required power2Double,FGrade insulation, power supply is380V，3Xiang,50HZProtection levelIP65At least every hour, it can be activated12 Next time.

h.The bridge is a truss style stainless steel structure with a width greater than1.2mIt has sufficient strength and stiffness, and the cantilever part has sufficient load-bearing capacity.

I.Each hyperbolic mixer must be equipped with1 Install lifting device.
