Description
Technical field
The invention belongs to blade and its agitating paddle technical field, and in particular to a kind of powerful stealth of tool extends the convex of swirling flow power
Face Dao Chang angles arc swirling flow anti-corrosion blade and long angle arc swirling flow anti-corrosion agitating paddle.The corrosion-proof agitating valve is that the oar of individual layer four is double
A variety of anticorrosions stirring in eight oar of layer or double-deck six oars of the oar of individual layer three, the tank being equipped with applied to required mixing agitating paddle, groove.
Background technology
Generally, in electrochemical industry, because mineral resources content declines, leaching solid-to-liquid ratio increase, manganese dioxide, manganese metal, electricity
The process specifications of the solution industry such as copper and electrolytic aluminium are updated, to be applicable the advanced technologies that its is changeable, manganese dioxide,
Agitating paddle technical requirements used are also higher, it is necessary to adapt to a variety of appearances in the tanks of the industries such as manganese metal, cathode copper and electrolytic aluminium, groove
The requirement such as product, kinds of processes, multiple technologies, in being operated in stirring at low speed, reduces in tradition stirring design and presses tank groove
Diameter 1/3rd is the numerical value of diameter of propeller blade, reaches that water conservancy diversion is good after blade operating, form stealthy big swirling flow, many fluidization towers and is inverted power
Greatly, liquid width stream length, liquid width stream is wide, to possess tens of kinds stealthy it is wavy it is powerful by even the anticorrosive of advanced technology type, high temperature resistance,
The requirement of high abrasion, realizes equal quick stirring, energy-conservation, consumption reduction, the purpose of volume increase.Current agitating paddle design method is substantially divided
For two major classes：One class is traditional oar of individual layer two or three oars, the two double-deck oars or three oars and individual layer diversion mixing oar, is produced during operating
Raw swirling flow power is small, and not enough, liquid is mixed, and the time is long, and deposition is arranged at bottom, and mixing effect is poor for many fluidization tower power.One class is Shen of the present invention
Another patent " a kind of large anticorrosion erosion agitating paddle and preparation method thereof " asked someone, completes the three-dimensional liquid fluid shape of agitating paddle
120 multinomial agitating paddles are demonstrated after many experiments to make and the three-dimensional fluid principles distributed force technology of stirring operation mixing, double-deck (bottom
The oar of arc four and the oar of upper straight-plate four) eight oars, three layers of (oar of bottom straight plate two, the oar of middle arc four, the oar of upper straight-plate four) ten oar, category system matches somebody with somebody
The multinomial invention of set, such as runner appearance, blade thickness, agitating shaft strengthens anti-corrosion, integral seamless connection, mold design and preparation,
The several inventive techniques and serial application of reactive phenolic resin material, mixing effect are better than tradition, but at 36 to 62 turns per minute
When double-deck eight oars produce big swirling flow, many fluidization towers, stretching force, stealthy wavy powerful power not enough, being applicable various cubical contents changes has office
It is sex-limited.
