Abstract
The present invention discloses a novel uniform diffuser for a flow field, which belongs to the application domain of spinning hydromechanics. On the existing basis of an air inlet, an air outlet and a diffusion tube, a turbulent diffusion theory of the flow field is used. The process dimension of the diffusion tube is redesigned, and a first flow equalization plate A and a second flow equalization plate B provided with rectangular holes are additionally arranged in the diffusion tube. Thus, the present invention has the advantages of short flow equalization length, even liquid distribution, small space occupation, etc.
Description
Technical field:
The invention belongs to weaving hydrodynamics Application Areas, it relates to a kind of even flow field diffuser.
Technical background:
In many workplaces, the flow field whether stablize the stability characteristic (quality) that directly has influence on duty.It is by prolonging the diffusion length H of anemostat 13 that existing even flow field diffuser 1 fluid state changes
1Realize the even continous-stable in flow field, as shown in Figure 1, common diffusion tube lengths H
1Be 3 times of diffusion area equivalent diameter.Gather the anemostat that spins or closely spin etc. on the equipment but be applied at present, because it is arranged on the bottom in slit between two row's rove lift spindles on the spinning locomotive or holder ingot, its locus is very little, can't pass through diffusion length H
1Realize that fluid is continuous, even, stable, solve, will directly affect the output and the quality of final products as not managing.
Summary of the invention:
In order to solve above-mentioned this technical barrier, be convenient in less space, realize the even diffusion in flow field, stable with the flow field that reaches negative pressure or malleation duty, the present invention utilizes the DIFFUSION IN TURBULENCE principle to provide the diffusion length of anemostat obviously to reduce, and can guarantee the new idea of a kind of even flow field diffuser that even flow field is stable again.
The technical scheme of technical solution problem of the present invention is as follows:
A kind of even flow field diffuser, it comprises air inlet 21, gas outlet 22, anemostat 23, the length a that it is characterized in that described anemostat 23 is 0.30～5.50 meter, the width b of anemostat 23 is 0.10～2.50 meter, the height c of anemostat 23 is 0.10～2.50 meter, it also comprises the first homogenizing plate A of the band rectangular opening that its periphery is connected with anemostat 23, the length a of the first homogenizing plate A of its band rectangular opening
1Be 0.30～5.50 meter, the width b of the first homogenizing plate A of band rectangular opening
1Be 0.10～2.50 meter, the thickness w of the first homogenizing plate A of band rectangular opening
1Be 0.50～1.50 millimeter, the first homogenizing plate A of band rectangular opening is apart from the height c of anemostat 23 upper surfaces
1It is 0.10～2.50 meter and by reinforcing the corresponding second homogenizing plate B that is suspended in anemostat 23 tops of 4 steel wires of 4 apertures on the second homogenizing plate B, the length a of its second homogenizing plate B
2Be 0.20～4.50 meter, the width b of the second homogenizing plate B
2Be 0.08～2.20 meter, the thickness w of the second homogenizing plate B
2Be 0.50～1.50 millimeter, the second homogenizing plate B is apart from the height c of anemostat 23 upper surfaces
2Be 0.05～1.75 meter, its periphery should with 0.05～0.50 meter at interval of anemostat 23.
Described anemostat 23, the first homogenizing plate A of described band rectangular opening, the described second homogenizing plate B all adopts aluminium alloy plate or iron sheet or steel plate to make.
Advantage compared with prior art of the present invention is:
Traditional even flow field diffuser generally all takes to spread conduit, normal conditions are to connect flat, circle with circle to connect rectangle, roundlet and connect the change that various forms such as great circle is realized the flow field form, simultaneously guarantee that again the flow field of working region is the current stabilization attitude, above-mentioned various interface form all needs quite long spatial transition, is difficult to realize in the regional space small range.The present invention then can be installed in the narrow and small scope of regional space, is applicable to require to suck air-flow each branch flow on whole distribution of lengths and the occasion of negative pressure uniformity, can satisfy technological requirement again.So the present invention have current-sharing length weak point, even fluid distribution, the advantage such as little that takes up space.
