Stirring blade

Technical Field

The utility model relates to the field of stirring equipment, in particular to a stirring blade.

Background

Stirring is a common operation in experiments and production, and aims to fully mix reactants and avoid the conditions of higher or lower local concentration, uneven heating and the like caused by uneven concentration of the reactants. Through stirring, the reactants are fully mixed and uniformly heated, the reaction time is shortened, and the reaction yield is improved.

The shaft power (P), the blade liquid discharge capacity (Q), the pressure head (H), the blade diameter (D) and the stirring speed (N) are five basic parameters describing a stirrer. The liquid discharge quantity of the paddle is in direct proportion to the flow standard number of the paddle, the first power of the rotating speed of the paddle and the third power of the diameter of the paddle. The shaft power consumed by stirring is in direct proportion to the specific gravity of the fluid, the power standard number of the blade, the third power of the rotating speed and the fifth power of the diameter of the blade. Under the condition of certain power and paddle form, the paddle liquid discharge amount (Q) and the pressure head (H) can be adjusted by changing the matching of the diameter (D) and the rotating speed (N) of the paddle, namely, the large-diameter paddle is matched with a stirrer with low rotating speed (ensuring the constant shaft power) to generate higher flow action and lower pressure head, and the small-diameter paddle is matched with high rotating speed to generate higher pressure head and lower flow action.

The stirring blades currently available on the market are equipped with only one form of blade, such as: propeller type agitator, turbine formula agitator, paddle agitator etc. generally can only stir the gas-liquid of same horizontal plane, lean on the interaction force between the liquid to drive the ascending gas-liquid of vertical side and follow the motion, and stirring efficiency is lower, and the mixed effect is not good.

Detailed Description

The following description of the embodiments of the present invention will be further described with reference to the accompanying drawings, wherein for the purpose of facilitating explanation, the upper, lower, left, right, front, rear, etc. orientations may be defined in the application, and the definitions are intended to facilitate clear description of the relative positions of the structures, and are not intended to limit the actual orientations of the products during the manufacturing, use, sale, etc. The following further describes embodiments of the present invention with reference to the accompanying drawings:

example one

Referring to fig. 1 and fig. 2, the present embodiment provides a stirring blade, which includes a stirring shaft 1 and a blade 2. The number of the blades 2 is two, one of the blades is a spiral blade 21, a spiral guide line of the spiral blade 21 is a conical spiral line, and the spiral guide line drives liquid (stirring object) to spirally rise when rotating; the other is a saw-tooth type blade 22, and the maximum diameter of the saw-tooth type blade 22 is larger than that of the spiral type blade 21. The screw type paddle 21 is located above the sawtooth type paddle 22, and the smaller end of the screw type paddle 21 is close to the sawtooth type paddle 22. The spiral blades 21 and the sawtooth blades 22 are coaxially arranged on the stirring shaft 1, and the sawtooth blades 22 are positioned at one end of the stirring shaft 1 and are driven by the stirring shaft 1 to rotate.
