Description
Technical field
A kind of high-performance circular arc variable cross-section stirring paddle, belongs to agitating device technical field.
Background technology
Present stage, in aluminium oxide hydrometallurgy production process, all kinds of agitator tanks generally adopt paddle agitating device, stirring paddle many employings hinged joint oar. The blade of hinged joint oar is flat, has angle with the surface of revolution, and about 30 �� ~ about 45 ��, incline direction is contrary with liquid stream direction of rotation. In use find following problem: 1, owing to hinged joint paddle blade is a clinoplain, liquid stream is transferred suddenly when running into blade, produce bigger resistance; 2, fluid is running into after blade flow direction transfers, and is not all discharge from blade bottom, but major part is discharged from blade bottom, makes whipping performance reduce; 3, when diameter of propeller blade is very big, blade easily snaps off or deforms, insufficient strength, only increases vane thickness and solves problem on deformation, adds cost of manufacture. Therefore, the mixing effect of hinged joint oar and energy consumption index are all relatively low.
Summary of the invention
Technical problem to be solved in the utility model is: overcome the deficiencies in the prior art, it is provided that the high-performance circular arc variable cross-section stirring paddle that a kind of resistance is little, whipping performance good, intensity is high.
This utility model solves its technical problem and the technical scheme is that this high-performance circular arc variable cross-section stirring paddle, including blade, the longitudinal section of blade is circular arc, it is characterized in that: described root of blade is fixedly connected with adpting flange by blade fulcrum, the width of blade outwards becomes narrow gradually from root along its length.
Increasing blade fulcrum at blade tip, blade tip connects adpting flange by blade fulcrum is fixing, is effectively increased the intensity of blade. Utilize adpting flange as connection member, it is possible to by reducing blade from end height, to make blade possess the function of scraper.
The cross section radian of described blade outwards tapers into from the inner being connected with blade fulcrum along its length, and outer chamfer is arranged. Blade surface is shaped as circular arc variable cross-section, and angle tapers into outward from the inner, and it is arc transition that blade meets stream limit, produces resistance less, makes energy consumption reduce.
The junction of described blade fulcrum and adpting flange is provided with gusset. Increase the bonding strength between blade fulcrum and adpting flange by gusset, increase the rotational strength when stirring of blade further.
The embedded connection blade fulcrum of described blade tip, blade props up shaft end and is correspondingly provided with grafting draw-in groove. It is stuck in blade fulcrum a part by Embedded for blade, namely adds the inner intensity to middle part of blade cleverly, play the effect drawn and support, effectively prevent deformable blade.
The tangential direction that described blade meets stream limit is parallel with blade gyratory directions.
Described blade goes out to flow limit and is gradually curved, parallel with liquid flow movement direction.
Compared with prior art, this utility model is had the beneficial effect that
1, intensity is high: increase blade fulcrum at blade tip, and blade tip connects adpting flange by blade fulcrum is fixing, is effectively increased the intensity of blade. Utilize adpting flange as connection member, it is adaptable to the uniformity requirements a kind of high-performance circular arc variable cross-section stirring paddle compared with high de-agglomeration groove, there is high mixing homogeneity, low energy consumption, low sheraing, good suppression precipitation feature.
2, resistance is little, energy-conservation: blade surface is shaped as circular arc variable cross-section, and angle tapers into outward from the inner, and it is arc transition that blade meets stream limit, produces resistance less, makes energy consumption reduce.
3, prevent deformation, be stuck in blade fulcrum a part by Embedded for blade, namely add the inner intensity to middle part of blade cleverly, play the effect drawn and support, effectively prevent deformable blade; And, it is provided with gusset in the junction of blade fulcrum Yu adpting flange, increases the bonding strength between blade fulcrum and adpting flange by gusset, increase the rotational strength when stirring of blade further.
4, also can reducing blade from end height, make blade possess the function of scraper, reduce buildup bottom bottom land, blade is low the end of from, and in rotary course, blade not only acts as immixture and also acts as scraper effect, bottom buildup is swept.
Accompanying drawing explanation
Fig. 1 is the structural representation of high-performance circular arc variable cross-section stirring paddle.
Wherein, 1, blade 2, blade fulcrum 3, gusset 4, adpting flange.
Detailed description of the invention
Fig. 1 is most preferred embodiment of the present utility model, below in conjunction with accompanying drawing 1, this utility model is described further.
With reference to accompanying drawing 1: a kind of high-performance circular arc variable cross-section stirring paddle, including blade 1, blade fulcrum 2, gusset 3 and adpting flange 4, the longitudinal section of blade 1 is circular arc, one end of blade 1 length direction is provided with blade fulcrum 2 and adpting flange 4, and blade 1 root is fixedly connected with adpting flange 4 by blade fulcrum 2.
The width of blade 1 outwards becomes narrow gradually from the inner being connected with blade fulcrum 1 along its length, the cross section radian of blade 1 outwards tapers into from the inner being connected with blade fulcrum 1 along its length, also can outwards being tapered into from the inner being connected with blade fulcrum 1 along its length by the section thickness of blade 1, the outer chamfer of blade 1 is arranged.
Also can be provided with gusset 3 in the junction of blade fulcrum 2 with adpting flange 4, gusset 3 can be provided with multiple, annular is distributed on the junction of blade fulcrum 2 and adpting flange 4, increase the bonding strength between blade fulcrum 2 and adpting flange 4 by gusset 3, increase the blade 1 rotational strength when stirring further.
Wherein, blade 1 end insertion type connects blade fulcrum 2, and blade fulcrum 2 end is correspondingly provided with grafting draw-in groove, it is stuck in the interior part of blade fulcrum 2 by Embedded for blade 1, namely add the intensity at blade 1 the inner to middle part cleverly, play the effect drawn and support, effectively prevent deformable blade.
Also the part that blade fulcrum 2 is connected with blade 1 can be made the arcwall face adapted with blade 1, it is ensured that together with blade fulcrum 2 is fitted and connected with blade 1, in order to increase the intensity of blade 1.
The tangential direction that blade 1 meets stream limit is parallel with blade gyratory directions. Blade 1 goes out to flow limit and is gradually curved, parallel with liquid flow movement direction. Blade 1 is provided with 2 ~ 6 groups. 2 ~ 6 groups of blades 1 are respectively provided with corresponding blade fulcrum 2 and adpting flange 4, then formed and be applicable to the uniformity requirements a kind of high-performance circular arc variable cross-section stirring paddle compared with high de-agglomeration groove, there is high mixing homogeneity, low energy consumption, low sheraing, good suppression precipitation feature; Purpose is to make liquid stream change flow direction gradually when running into blade 1, blade is rotated and produces less resistance; Effectively reduce the liquid stream flowed out from blade 1 top edge, improve blade 1 whipping performance. Also by reduce blade 1 from end height, make blade possess the function of scraper, blade 1 is low the end of from, and in rotary course, blade 1 not only acts as immixture and also acts as scraper effect, bottom buildup is swept, and reduces buildup bottom bottom land.
