Example 2

On the basis of example 1, the stirring power is calculated according to the formula:

Re＝n×d³×ρ/μ

in the formula: n- - -revolution, in min;

d- -impeller diameter, in m;

rho- - -density, in kg/m 3;

mu- - - -viscosity in kg/m3 s.

The rotating speed of the stirrer is 60r/min, the diameter of the paddle is 0.2m, according to the inquiry of a hardware handbook, the density of the common clay is 1.7 g per cubic centimeter, namely 1700 Kg per cubic meter, the viscosity of the clay is 500MPa s, and the conversion is 5000Kg s/m²。

The stirring force is calculated according to the formula:

F_N＝RexS

in the formula: re- - -stirring power;

s- - -stirring time, unit min.

σ_max≤[σ]

from the strength conditions, it can be seen that:

A≥F_N，max/[σ]

the allowable stress of the fan blade is known to be 137Mpa,

handle [ sigma ]]＝137，F_N，maxSubstituting 14.79 into formula to calculate A ≧ F_N，max/[σ]＝0.1079m2。

And the length of the cross section is 50mm, so that the available width is 2.158 cm. That is, the minimum wall thickness must be greater than or equal to 2.158cm, and to ensure that the safe wall thickness is 2.5cm, the safety factor is 1.3, and the final wall thickness is 3.25 cm.
