Utility model content
For the defect existed in prior art, the utility model provides a kind of plumbous alloy melt stirring device with closing in type guide shell, in agitated kettle, guide shell is set, and this guide shell has the bottom of reducing, the structure that formation is similar to " Venturi tube ", plumbous liquid stream from the coarse to fine, to accelerate flow velocity, accelerate the backflow up and down of plumbous liquid.
Concrete technical scheme of the present utility model is as follows:
A kind of plumbous alloy melt stirring device with closing in type guide shell, comprise agitated kettle, be positioned at the erecting bed directly over agitated kettle, described erecting bed is equipped with motor, motor is connected with the paddle stretched in agitated kettle, the coaxially arranged guide shell having bottom open in described agitated kettle, and the top of guide shell is provided with the opening causing plumbous liquid to enter, described paddle is positioned at guide shell, and guide shell is fixed on bottom erecting bed by suspension;
Described guide shell has the shell portion being positioned at paddle bottom, and described shell portion is closing in type, and the internal diameter to the shell portion of downward-extension reduces gradually, and the maximum amplitude that reduces should be less than 10%.
The shell portion of the utility model to paddle bottom improves, and is set to closing in type, and the internal diameter of the shell portion to downward-extension is reduced gradually, when the plumbous liquid that paddle stirs is by this section, form Venturi effect, accelerate the flowing velocity of plumbous liquid, to reduce power of motor; The amplitude that reduces simultaneously controlling the narrowest place, bottom should be less than 10%, avoids the outlet bottom guide shell too small, increases the burden of paddle.
Preferably, described paddle comprises the shaft that is connected to motor and is fixed on the stirring ring bottom shaft by strut, and described stirring ring outer peripheral face is evenly distributed with paddle, and described strut is provided with stirring plate.
Adopt the paddle of annular, increase the sphere of action and speed that stir ring, and arrange paddle at the outer peripheral face stirring ring, coordinate the stirring plate in strut, the plumbous liquid stirred inside and outside ring is stirred, promotes the bottom that plumbous liquid flows to guide shell.
Preferably, the bottom of described guide shell is the outlet of plumbous liquid, the barrel thickening that plumbous liquid exit is corresponding.Because the flowing of plumbous liquid is accelerated, easily corrode the barrel at bottom opening place, barrel herein thickeies, and to overcome the erosion of plumbous liquid, alleviates barrel excessively thinning.
Preferably, described shell portion is no more than 1/2nd of whole guide shell height, avoids the stroke of plumbous liquid in shell portion long, affects the speed bottom plumbous liquid outflow tube.
Preferably, described suspension has at least two jaws fixing with guide shell, each jaw is provided with three locking points, each jaw is provided with three fixed heads, each fixed head is connected with cylindrical shell by bolt at locking point place, keep the position of guide shell in agitated kettle to greatest extent, avoid plumbous liquid to flow and guide shell is had an impact.
The utility model by arranging guide shell in agitated kettle, and this guide shell has the bottom of reducing, forms the structure being similar to " Venturi tube ", plumbous liquid stream from the coarse to fine, to accelerate flow velocity, accelerate the backflow up and down of plumbous liquid.
