The lower jet agitator that suspends is subject to frictional force combined effect between gravity, the reverse towing force of downward jet flow liquid, splined shaft and hub splines, meeting relative liquid surface certain position suspension stirring, and blade inclination angle is stepped up making the liquid stream series connection downward jet flow of speed-raising；The blade inclination angle swept on end agitator increases once again, the blade jet flow made under suspension on jet agitator is raised speed downward jet flow once again on the conical surface of cone bucket, forms tubaeform injection stream, impacts drum head after high speed diffusion, play large area without dead angle sweep the end stirring, it is prevented that material settle.
Cone struggles against close to drum head, and upwards drain during rotation is thrown away by jet pipe rotating centrifugal, overcomes the defect for stirring dead angle immediately below axle center.
It is that streamline Airfoil Sections constitutes paddle cross section, rotating speed is higher, energy-conservation, sweep the end that the design relatively generally stirs, and main incidentally stirs whole material sweeping anti-being deposited as in the end, makes solid-liquid distribution substantially uniform.When rotating speed is relatively low, the lower jet agitator that suspends can be seated on lower positioning step, and liquid stream speed-raising undershoot of entirely connecting is swept at the end, and low energy consumption prevents sedimentation, completes stirring operation；When rotating speed promotes, the lower jet agitator that suspends can because liquid stream recoil rises to the position that relative liquid surface is suitable, if rising once again, the blade of the superiors can depart from liquid level, makes load reduce, and undershoot assists stirring supernatant liquid, forms good stirring convection circulation.
Compared with prior art, beneficial effects of the present invention also resides in:
Bottom is impacted downwards in the from top to bottom series connection speed-raising always of center liquid axial flow, makes bottoms material suspend good, will not settle；The Electrical Priority consumed carries out liquid stream and sweeps end elimination sedimentation, then lets nature take its course to be converted to stirring again, makes liquid phase solid phase in whole bucket substantially uniform, and this operation principle is both to have met instructions for use, key significantly energy-conservation again.
The lower jet agitator that suspends suspends, and stirring is automatic adapts to different liquid level, completes stirring.
Sweep the suction effect of penetrating of end agitator and completely solve axial flow stirring dead angle immediately below axle.
Bottom is bored bucket-shaped jet flow and is coordinated central jet, and perfect realization sweeps the end, it is prevented that sedimentation.
The paddle middling speed that axial flow uses rotates, and power consumption is very low, and mixing effect is fine, particularly sweeps the urceolus of end agitator and bores bucket when higher rotation speed, and internal and external walls liquid can play liquid-bearing supporting role, makes stirring reliable and stable.
Even if the design has a power failure for a long time causes that material settles completely, as the only small timely light start stirring of torque, and by deposition material surface progressively axial flow jet flow deeply, until horn-like liquid stream sweeps the end, material sedimentation being completely eliminated, enters normal stirring, highly difficult stirring adaptability is especially good.
