Description
Technical field
This utility model relates to a kind of experiment stirring paddle, belongs to teaching aid field.
Background technology
Stirring is to occur certain to circulate by agitator so that the granule that the gas in solution, liquid even suspend is able to
Mix homogeneously.And in order to reach this purpose, need to be realized by forced convertion, mixed uniformly device, i.e. agitator
Internals.Stirring generally uses stirring rod, stirring paddle etc. to be stirred operation, conventional stirring paddle form have anchor formula, paddle,
Turbine type, push type, frame etc., but when being stirred, it often has the appearance in the inefficient district of stirring, causes stirring inequality
Even, and mixing speed is slow, and the uniformity of stirring is the highest, is unfavorable for the carrying out of experiment.
Utility model content
The technical problems to be solved in the utility model is for above not enough, it is provided that a kind of experiment stirring paddle, has and stirs
Mix uniformly, avoid the appearance of eddy current, avoid the appearance in the inefficient district of stirring, improve the uniformity of stirring and accelerate stirring speed
The advantage of degree.
For solve above technical problem, this utility model by the following technical solutions:
A kind of experiment stirring paddle, including rotating shaft, described rotating shaft is provided with four blade type blades, the cross section of blade type blade in
Rectangle；
Described blade type blade is 30 ° with the axis angle of rotating shaft；
Described four blade type blades are crosswise distribution along the axis of rotating shaft；
Being connected between described blade type blade and rotating shaft and have three connecting rods, three connecting rods are arranged in parallel；
Distance between described adjacent links is equal；
Described connecting rod is fixing with blade type blade and rotating shaft respectively to be connected；
The radius of described connecting rod is less than the width of blade type blade；
Described connecting rod is the cylindrical body of rod, and the angle between axis and the axis of rotating shaft of connecting rod is 75 °；
Described connecting rod is provided with several spines, and several spines are circular helix distribution along connecting rod；
Being shaped as of described spine is coniform, and the drift angle of spine is 15 °；
The height of described spine and the equal diameters of connecting rod.
The following is and the further of such scheme is optimized:
Described rotating shaft is provided with the first ring for fixing and the second ring for fixing, and the first ring for fixing is positioned at the top of the second ring for fixing；
Described first ring for fixing and the second ring for fixing be arranged in parallel；
The axis of described rotating shaft, the first ring for fixing and the second ring for fixing is on same straight line；
The radius ratio of described first ring for fixing and the second ring for fixing is 2:1；
Connect between described first ring for fixing and the circle body of the second ring for fixing and have four blade type blades；
Described blade type blade is fixing with the first ring for fixing and the second ring for fixing respectively to be connected.
After this utility model uses above technical scheme, compared with prior art, have the advantage that this utility model fills
Put stirring more uniform, it is to avoid the appearance of eddy current, reduce the appearance in the inefficient district of stirring, improve the speed of stirring, carry
The high uniformity of liquid, the uniformity of ratio convention stir improves more than 50%, improves more than 60% than convention stir speed.
With embodiment, this utility model is described in detail below in conjunction with the accompanying drawings.
Accompanying drawing explanation
Accompanying drawing 1 is the structural representation of this utility model device；
Accompanying drawing 2 is the top view of accompanying drawing 1；
In figure,
1-rotating shaft, 2-the first ring for fixing, 3-the second ring for fixing, 4-blade type blade, 5-connecting rod, 6-spine.
Detailed description of the invention
Embodiment, as shown in Figures 1 and 2, a kind of experiment stirring paddle, including rotating shaft 1, rotating shaft 1 is provided with first
Ring for fixing 2 and the second ring for fixing 3, the first ring for fixing 2 is positioned at the top of the second ring for fixing 3；
First ring for fixing 2 and the second ring for fixing 3 be arranged in parallel；
The axis of rotating shaft the 1, first ring for fixing 2 and the second ring for fixing 3 is on same straight line；
The radius ratio of the first ring for fixing 2 and the second ring for fixing 3 is 2:1；
Connect between first ring for fixing 2 and the circle body of the second ring for fixing 3 and have four blade type blades 4, the cross section of blade type blade 4
It is rectangle；
Blade type blade 4 is fixed be connected with the first ring for fixing 2 and the second ring for fixing 3 respectively；
Blade type blade 4 is 30 ° with the axis angle of rotating shaft 1；
Four blade type blades 4 are crosswise distribution along the axis of rotating shaft 1；
