Description
Technical field
The present invention relates to stirred tank, be specifically related to the agitator of stirred tank.
Background technology
Stirred tank comprises agitator and kettle, and agitator comprises shaft and impeller.Existing agitator is single impeller structure, and the radial plate blade that the blade of impeller is band steel to be made, shape is unreasonable, therefore mixing effect is undesirable.
Summary of the invention
The technical problem to be solved in the present invention is to provide the good agitator of a kind of mixing effect.
In order to solve the problems of the technologies described above, technical scheme of the present invention is:
A kind of agitator of stirred tank, comprise hollow shaft, upper impeller and lower impeller, upper impeller and lower impeller all have the bending plate blade of circular arc, the axis being parallel of plate blade is in hollow shaft axis, upper impeller plate blade tilts upward and is arranged so that the outer end of plate blade is higher than its root, lower impeller plate blade is tilted to down and is arranged so that the root of plate blade is higher than its outer end, the top of hollow shaft is provided with the air inlet for linking up air duct in gas piping and hollow shaft, middle air duct is arranged the check valve allowing gas descending, in hollow shaft, the bottom of air duct arranges filter element.
The agitator of above-mentioned stirred tank, upper impeller plate blade positive pitch b is 5-30 °; Better, b is 10-25 °; More preferably, b is 15 °.
The agitator of above-mentioned stirred tank, the downward inclination angle c of lower impeller plate blade is 5-30 °; Better, c is 10-25 °; More preferably, c is 15 °.
The agitator of above-mentioned stirred tank, the middle air channel diameter of hollow shaft is the 1/5-1/2 of hollow shaft external diameter.
The agitator of above-mentioned stirred tank, the central angle of the plate blade that circular arc bends is 10-30 °.
The agitator of above-mentioned stirred tank, filter element is screen pack.
Hollow shaft is arranged upper and lower two impellers, upper and lower two impellers all have circular arc and bends plate blade, upper impeller blade updip is arranged, lower impeller blade has a down dip setting, when shaft drives upper and lower wheel rotation, forms negative pressure between upper and lower two impellers, upwards flow in the upper strata of the liquid in reactor between upper and lower two impellers, lower floor flows downward, and make mixing fully, mixing effect is good.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the present invention is described in more detail:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the top view of upper impeller.
In figure: 1 air inlet, air duct in 2,3 hollow shafts, impeller plate blade on 4,5 check valves, 6 times impeller plate blades, 7 filter elements.
Detailed description of the invention
As depicted in figs. 1 and 2, the agitator of stirred tank comprises hollow shaft 3, upper impeller and lower impeller.Upper impeller and lower impeller all have the bending plate blade of circular arc, and the axis (center line that namely circular arc is bending) of plate blade is parallel to hollow shaft axis.Upper impeller plate blade 4 tilts upward and is arranged so that the outer end of plate blade is higher than its root, lower impeller plate blade 6 is tilted to down and is arranged so that the root of plate blade is higher than its outer end, on the whole, on upper impeller plate blade screw, under lower impeller plate blade screw.The top of hollow shaft is provided with the air inlet 1 for linking up air duct 2 in gas piping and hollow shaft, and middle air duct is arranged the check valve 5 allowing gas descending, in hollow shaft, the bottom of air duct arranges filter element 7.When shaft stops operating, gas can be passed into by gas piping in air duct in hollow shaft, wash bottom precipitation thing open, reach better mixing effect.
Because existing stirrer shaft flow impeller stirring scope is less, reactor core feed liquid only can be made to mix, impeller of the present invention makes feed liquid produce radial and axial motion simultaneously, stirring scope is increased, and form negative pressure between upper impeller and lower impeller, and this negative pressure is perpendicular to skewness on axial plane, feed liquid mixed effect improves.
Preferably, upper impeller plate blade positive pitch b is 5-30 °; Better, b is 10-25 °; More preferably, b is 15 °.
Preferably, the downward inclination angle c of lower impeller plate blade is 5-30 °; Better, c is 10-25 °; More preferably, c is 15 °.
Preferably, the middle air channel diameter of hollow shaft is the 1/5-1/2 of hollow shaft external diameter.
Preferably, the central angle d of plate blade that circular arc bends is 10-30 °.
Preferably, filter element is screen pack.
