Abstract
The invention discloses a macroporous flow-through type stirring paddle blade, relates to a stirring paddle blade and particularly relates to the macroporous flow-through type stirring paddle blade. The macroporous flow-through type stirring paddle blade disclosed by the invention has the advantage that the problems that a conventional vertical-axis type paddle plate stirrer is poor in stirring and mixing effect and long in stirring time and uses multiple equipment to stir simultaneously so as to increase the energy consumption and investment are solved. The macroporous flow-through type stirring paddle blade comprises a blade main body, wherein the surface of the blade main body is a concave curved surface and is provided with a plurality of long-stripy through holes. The macroporous flow-through type stirring paddle blade is used for stirring in a flocculating tank.
Description
Technical field
The present invention relates to a kind of stirrer paddle, be specifically related to a kind of macropore spray-type stirrer blade sheet.
Background technology
The traditional perpendicular axis type paddle board agitator of the most of use of water factory's machinery flocculation basin at present, impeller is cross and installs.Eight paddle boards of shape on an axle.The blade all vertical water surface rotates, and in operational process, current are mainly horizontal flow, promote the mixing of flocculation agent and former water, for micro-flocs unit provides the collision opportunity that flocculates in the same way.But this kind of method current direction is single, and stirring and mixing effect is not high, after stirring for a long time, could form required big or small flocs unit; On the other hand, stir generation whirlpool and in shattering process, lose portion of energy.For improving mixing effect, be generally that three to four stirrers are set in flocculation basin, between each grade of stirrer, with partition wall, separate to prevent water flow short-circuit, but this kind of method equipment investment to be many, energy consumption and investment are higher.
Summary of the invention
The present invention is poor for solving traditional perpendicular axis type paddle board agitator stirring and mixing effect, and churning time is long, uses multiple devices to stir simultaneously and increased the problem of energy consumption and investment, and then proposes a kind of macropore spray-type stirrer blade sheet.
The present invention addresses the above problem the technical scheme of taking to be: the present invention includes blade body, blade body surface is recessed curved surface, and blade body surface has a plurality of long strip shape through holes.
The invention has the beneficial effects as follows: it is faster that the liquid that the present invention is flowed out from each long strip shape through hole in whipping process can make to flow through from blade body both sides the speed of liquid, thereby additionally increased velocity slope, strengthen the shearing motion of current, improved the turbulence level of fluid; When blade body and fluid do relative motion, constantly cutting fluid, forms hole jet, forms relative adverse current with the makeup water stream after blade body, can form stable little vortex; When the present invention uses, blade body and the water surface have certain angle, and hole jet and the horizontal plane shape of formation form an angle, and have strengthened the collision of fluid between the different heights water surface, have increased micro-flocs unit effective collision of different aspects, improve flocculation efficiency; The shadow area of stirring movement direction of the present invention is large, and the present invention effectively raises flocculation efficiency, can reduce agitator number in flocculation basin, reduces flocculation time, has reduced on the whole energy consumption.
Accompanying drawing explanation

The technique effect of present embodiment is: so arrange, make that fluid in whipping process can rule through each blade body 1, and the jet of formation rule.Other composition and annexation are identical with embodiment one.
Embodiment three: in conjunction with Fig. 1, Fig. 2 and Fig. 3, present embodiment is described, a kind of length of each long strip shape through hole 1-1 and ratio of width of macropore spray-type stirrer blade sheet is 4:1 described in present embodiment.Other composition and annexation are identical with embodiment one or two.
Embodiment four: in conjunction with Fig. 1, Fig. 2 or Fig. 3, present embodiment is described, a kind of length of each long strip shape through hole 1-1 and ratio of width of macropore spray-type stirrer blade sheet is 6:1 described in present embodiment.
The technique effect of present embodiment is: so arrange, effectively controlled the flow through the fluid of each long strip shape through hole 1-1.Other composition and annexation are identical with embodiment three.
Embodiment five: in conjunction with Fig. 1, Fig. 2 or Fig. 3, present embodiment is described, a kind of cross section of blade body 1 of macropore spray-type stirrer blade sheet is circular arc described in present embodiment, and the radian of described circular arc is 15 °～45 °.
The technique effect of present embodiment is: so arrange, make blade body 1 frangibility not in whipping process, extended blade work-ing life.Other composition and annexation are identical with embodiment one.
