Abstract
The invention provides a stirrer of a stirred tank. The stirrer has good stirring effects. The stirrer comprises a hollow mixer shaft, an upper impeller and a lower impeller. The upper impeller and the lower impeller are provided with arc bent flat-blades. The axes of the arc bent flat-blades are parallel to the axis of the hollow mixer shaft. The arc bent flat-blades of the upper impeller inclines upward so that outer ends of the arc bent flat-blades are higher than root parts of the arc bent flat-blades. The arc bent flat-blades of the lower impeller inclines downward so that root parts of the arc bent flat-blades are higher than outer ends of the arc bent flat-blades. An upper part of the hollow mixer shaft is provided with a gas inlet for communication between a gas pipe and a hollow gas tunnel of the hollow mixer shaft. The hollow gas tunnel is provided with a one-way valve allowing downward flowing of gas. The bottom end of the hollow gas tunnel of the hollow mixer shaft is provided with a filtration part.
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 the single impeller structure, and the blade of impeller is the radially plate blade that band steel is made, and shape is unreasonable, so mixing effect is undesirable.
Summary of the invention
The technical problem to be solved in the present invention provides 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, last impeller and following impeller, last impeller and following impeller all have the plate blade of circular arc bending, the axis of plate blade is parallel to hollow shaft axis, last impeller plate blade is tilted to the outer end that is arranged so that plate blade and is higher than its root, following impeller plate blade is tilted to down the root that is arranged so that plate blade and is higher than its outer end, the top of hollow shaft is provided with the air inlet for the air duct of linking up gas piping and hollow shaft, arrange on the middle air duct and allow the descending check valve of gas, the bottom of air duct arranges filter element in the hollow shaft.
The agitator of above-mentioned stirred tank, last 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 following 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 of circular arc bending are 10-30 °.
The agitator of above-mentioned stirred tank, filter element are screen pack.
Two impellers up and down are set on the hollow shaft, all has the crooked plate blade of circular arc up and down on two impellers, last impeller blade updip arranges, when the setting that has a down dip of following impeller blade, shaft drive up and down wheel rotation, form negative pressure between two impellers up and down, upwards flow between the upper strata of the liquid between two impellers up and down in the reactor, lower floor flows downward, and makes to mix fully, and mixing effect is good.
Description of drawings
Below in conjunction with accompanying drawing to further detailed explanation of the present invention:
Fig. 1 is structural representation of the present invention.
Fig. 2 is the vertical view of last impeller.
Among the 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.
The specific embodiment
As depicted in figs. 1 and 2, the agitator of stirred tank comprises hollow shaft 3, goes up impeller and following impeller.Last impeller and following impeller all have the plate blade of circular arc bending, and the axis of plate blade (being the center line of circular arc bending) is parallel to hollow shaft axis.Last impeller plate blade 4 is tilted to the outer end that is arranged so that plate blade and is higher than its root, following impeller plate blade 6 is tilted to down the root that is arranged so that plate blade and is higher than its outer end, on the whole, on the last impeller plate blade screw, under the following impeller plate blade screw.The top of hollow shaft is provided with the air inlet 1 for the air duct 2 of linking up gas piping and hollow shaft, arranges on the middle air duct to allow the descending check valve 5 of gas, and the bottom of air duct arranges filter element 7 in the hollow shaft.When shaft stops operating, can in the middle air duct of hollow shaft, feed gas by gas piping, wash the bottom precipitation thing open, reach better mixing effect.
Because it is less that existing agitator aial flow impeller stirs scope, only can make reactor core feed liquid mix, impeller of the present invention makes feed liquid produce radial and axial motion simultaneously, make the stirring scope increase, and form negative pressure between last impeller and the following impeller, and this negative pressure skewness on perpendicular to the axis plane, the feed liquid mixed effect improves.
Preferably, last 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 following 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 the plate blade of circular arc bending is 10-30 °.
Preferably, filter element is screen pack.
