Description
Technical field
The present invention relates to a kind of agitator, specifically relate to a kind of concentric double-shaft agitator that adopts hybrid outer oar.
Background technology
Stirring operation is widely used in the process industrials such as petrochemical industry, food, medicine, fermentation, sewage disposal.Along with process industrial to becoming more meticulous, maximization, energy-efficientization development, actual whipping process becomes and becomes increasingly complex, the variation of the transformation of phase, the transmission of heat and viscosity often exists simultaneously.For such complexity, variable working condition system, if directly adopt conventional agitator, be no matter low sticky or high sticky agitator, demand that all can not fine adaptation whipping process different phase, directly causes that process efficiency is low, Process Energy utilizes the problems such as unreasonable.
For guaranteeing that tank diameter inner fluid is mixed preferably, better meet the stirring demand of different phase in industrial production, a kind of more method of industrial employing is to develop, select twin shaft combined blender, and outer oar is selected the agitator that is applicable to high sticky system, and interior oar is selected rapid dispersion oar.But existing twin shaft combined blender, the structure of outer oar is generally more fixing, be mostly anchor, frame oar, also there is the outer oar of a small amount of helical-ribbon type to occur, but the occasion of the outer oar of application helical-ribbon type, the arrangement form of inside and outside oar is mostly vertical type, has the problem of movable sealing complexity, and this has limited the further raising of twin shaft combined blender performance to a certain extent.Therefore,, by the novel outer oar of innovative design, research and develop novel biaxial combined blender and there is very significant realistic meaning.
Summary of the invention
The object of this invention is to provide a kind of concentric double-shaft agitator that adopts hybrid outer oar, can be issued to good stirring and mixing effect in complicated, variable working condition system.
The object of the invention is to realize by the following technical solutions:
The present invention includes tank diameter, flange, outer shaft, interior shaft, hybrid outer oar, interior oar; Interior shaft is divided into upper and lower two sections, by flange, connects, and interior shaft epimere empty set stirs in axis hole outside, and outer shaft both sides are welded with symmetrical crossbeam, in tank diameter, hybrid outer oar and interior oar is housed, and tank diameter end socket center position is equipped with flange.
Described hybrid outer oar comprises two blade bracing frames, the two ribbons of cavity, oval blade, one end of two blade bracing frames is connected with described two beam-end respectively, the other end of a blade bracing frame is equipped with left ribbon, the other end of another blade bracing frame is equipped with right ribbon, left ribbon and right ribbon form the two ribbons of cavity, left ribbon and right ribbon link into an integrated entity by the vertical bar of both sides, the shaft hypomere that is arranged in the two ribbons of cavity is equipped with 1 above oar, left ribbon is connected with oval blade with right ribbon bottom, oval blade bottom shape is identical with tank diameter end socket shape, the oar footpath of hybrid outer oar is 0.9～0.98 times of tank diameter internal diameter.
Described flange is arranged symmetrically with the screwed hole that connects follow-up flange, has the hole being communicated with tank diameter end socket in the middle of flange.
Described interior oar is six flat blade disc turbine oar or six straight leaf open turbine oars or six oblique leaf open turbine oars.
The beneficial effect that the present invention has is:
1) contribute to form whole still circular flow, stirring and mixing effect is good.The two ribbon structures of cavity contribute to the formation of axial flow, and interior oar contributes to the discharge of radiation stream, simultaneously due to the existence of the oval blade in hybrid outer oar bottom, at the bottom of still position be uniformly mixed be improved significantly.
2) wide adaptability.By changing rotating speed, combination and the arrangement form of inside and outside oar, this concentric double-shaft agitator can adapt to different systems, in very wide range of viscosities, can keep good stirring and mixing effect, is particularly useful for high sticky and variable working condition system.
3) structure operates steadily.The existence of hybrid outer oar top reinforcement and the vertical bar in middle part, makes its held stationary in rotation process.
4) effectively avoid the existence of hydrops.Be different from conventional discharge gate form, tank diameter bottom is flanged structure, can effectively avoid the existence of hydrops.
