Abstract
The utility model relates to a self-balanced type casting turbine stirrer, which comprises three parts including an upper impeller, a hub and a lower impeller. In order to provide high convenience for manufacture, the manufacture process of the blades is completed by an individual cast and welding splicing process. The upper blade includes an upper wheel disc and an upper blade, the lower blade includes a lower blade and a lower wheel disc, the upper wheel disc and the lower wheel disc are distributed in parallel, the concordant axes are ensured, the eccentricity is avoided, the hub is connected with the upper wheel disc and the lower wheel disc and plays the role of connecting the wheel discs and a transmission shaft. The blades are arranged on the wheel discs; the included angle between the upper blade and the upper wheel disc and another included angle between the lower blade and the lower wheel disc are the same, but are opposite in directions. In the working process, the directions of the upper blade and the lower blade are opposite, as a result, the axial components of the reacting force generated by the inertia of a fluid are equal, but the directions are opposite, and the automatic balancing is implemented.
Description
Technical field
The utility model relates to a kind of self-balancing type casting turbine stirrer.
Background technology
Stirring reaction equipment is widely used in the industrial or agricultural fields such as chemical industry, pharmacy, the energy, biotechnology.In stirring reaction equipment, agitator has been mixing of materials, has promoted heat and mass and react the main parts size occurring, according to the viscosity that stirs purposes and material, agitator has various ways, and wherein turbine agitator is widely used in the stirring of low-viscosity (mobile) liquid.In low-viscosity (mobile) liquid whipping process, because the general design speed of agitator is more greatly to improve mixing effect.The turbine agitator for blade with certain angle of inclination, in agitator high speed rotating process, can produce larger axial force, the existence of axial force can affect the mechanical seal between shaft and reactor, also can change the natural frequency of vibration of power transmission shaft, brings potential danger.
Summary of the invention
The utility model discloses a kind of self-balancing type turbine stirrer.This agitator can be realized the self-balancing of power transmission shaft axial force, can not impact the natural frequency of vibration of sealing device and shaft and critical speed.
The utility model adopts following technical scheme:
The related self-balancing type impeller of the utility model comprises impeller, propeller boss and three parts of lower impeller, and for easily manufactured, the utility model adopts individual cast, welds the manufacture process that assembled technique completes impeller.Upper impeller is comprised of upper wheel disc and blade two parts, and lower impeller is comprised of lower blade and lower wheel disc two parts, and upper wheel disc and lower wheel disc are arranged in parallel, and guarantees that axis is consistent, and without acceptance of persons, propeller boss connects upper and lower two wheel discs, plays the effect that connects wheel disc and power transmission shaft.Blade is arranged on wheel disc, and blade and lower blade are identical with the angle between wheel disc, but opposite direction.In the course of work, due to the opposite direction of upper and lower two blades, therefore, the reaction force component producing due to the inertia of fluid in rotation process equates, but opposite direction, thereby the autobalance of realization.
Good effect of the present utility model is as follows:
Blade in the utility model is arranged symmetrically with, can automatically balancing axial force, so agitator can not apply additional axial load to shaft, ensures that the natural frequency of vibration of power transmission shaft is constant, can not exert an influence to the sealing load of mechanical sealing surface yet.Because the blade of agitator is arranged symmetrically with, when coaxial rotation, material is produced to rightabout active force, fluid is flowed with contrary or relative direction, thereby destroyed, be positioned near the mixing isolated area of agitator, can improve mixed effect, improve mixing efficiency.
The utility model is simple in structure, with low cost, and installation and maintenance is all very convenient, and stirring efficiency is high, has good applicability.
Accompanying drawing explanation
Accompanying drawing 1 is the utility model overall construction drawing;
Accompanying drawing 2 is view perpendicular to axial direction;
Accompanying drawing 3 is axial view.
In the accompanying drawings: wheel disc on impeller on 1,2 propeller boss, 3 times impellers, 4 times wheel discs, 5 lower blades, 6 blades, 7 axis holes, 8 keyways, 9.
The specific embodiment
As shown in Figure 1, the utility model is comprised of upper impeller 1, propeller boss 2 and lower impeller 3, and upper impeller 1 is provided with wheel disc 9 and blade 6, is provided with keyway 8 and axis hole 7 on propeller boss 2, is provided with lower wheel disc 4 and lower blade 5 on lower impeller 3; Upper wheel disc 9 and lower wheel disc 4 are arranged in parallel, and are connected with propeller boss 2, and the anchor ring of upper wheel disc 9 and lower wheel disc 4 is perpendicular to the axis of propeller boss 2.
As shown in Figure 2, blade 6 is connected with lower wheel disc 4 with upper wheel disc 9 respectively with lower blade 5, and blade 6 is identical with the physical dimension of lower blade 5, but incline direction is about the plane symmetry perpendicular to propeller boss 2 axis.
As shown in Figure 3, be provided with axis hole 7 in propeller boss 2, power transmission shaft is placed in axis hole 7, and interconnects by flat key and the propeller boss 2 being arranged in the keyway 8 on propeller boss 2, transmits motion and power.
During work, different according to power transmission shaft rotation direction, material respectively under the driving of upper impeller 1 and lower impeller 3 axis direction along power transmission shaft towards relative or contrary direction, move, the direction of motion of pipe fluid is not how, the axial component of the reaction force of the material that blade 6 and lower blade 5 are subject to all meets the equilibrium condition of equal and opposite in direction, opposite direction, therefore, agitator is realized the self-balancing in axial load, can not produce additional load to other parts; Because fluid is done relative or rightabout motion, the mixing isolated area between two impellers all can be destroyed, thereby improve mixed effect.
