Abstract
The invention relates to a novel venturi mixer which comprises a front segment, a middle segment and a rear segment, wherein the front segment comprises a mainflow inlet pipeline, a contraction segment and a front half throat part which are communicated sequentially; the middle segment comprises a disk-shaped connection structure communicated with the front half throat part and an introduced fluid introduction pipe which is arranged at one end of the disk-shaped connection structure and communicated with the disk-shaped connection structure; the rear segment comprises a rear half throat part, a diffusion segment and a mainflow outlet pipe which are communicated sequentially; the rear half throat part is communicated with the other end of the disk-shaped connection structure; the front segment and the rear segment are communicated coaxially through the middle segment; the front half throat part and the rear half throat part are inserted into the disk-shaped connection structure while the front half throat part is not in contact with the rear half throat part; and an annular passage, into which the introduced fluid flows, is formed between the front segment and the rear segment. The venturi mixer is used for the mixing of the gas and the fluid or between the fluids, and has the characteristics of being convenient to machine and assemble. In addition, the introduction speed of the introduced fluid can be regulated by regulating the gap of the flowing section of the introduced fluid.
Description
Technical field
The present invention relates to a kind of blender, be specifically related to a kind of Venturi blender.
Background technology
Venturi mixer, as a kind of important gas-liquid or liquid liquid mixing arrangement, has a wide range of applications in engineering reality.Common venturi mixer is made up of a classical venturi tube and the inlet tube that is arranged on throat side, and main flow fluid, by flowing through in classical venturi tube, is introduced fluid and flowed into through inlet tube, carries out blending with main flow fluid.Only introduce from throat's one side owing to introducing fluid, easily cause downstream fluid to mix even not, in addition, the sectional dimension of inlet tube cannot regulate, and often there will be main flow fluid to be pressed into the situation of inlet tube.
Summary of the invention
For solving above-mentioned problems of the prior art, the object of the present invention is to provide a kind of Venturi blender, there is processing and feature easy to assembly, and the gap that can introduce fluid passage section by adjustments reaches the object of adjustment introducing fluid introducing speed.
In order to achieve the above object, the technical solution adopted in the present invention is:
A kind of Venturi blender, comprises leading portion, interlude and back segment three parts, and described leading portion comprises the main flow flow ipe 1, contraction section 2 and the throat's first half 3 that are communicated with successively; Described interlude comprises the plate-like syndeton 4 being communicated with throat first half 3 and is arranged on plate-like syndeton 4 one end and the introducing fluid inlet tube 5 of its connection; Described back segment comprises that the throat's latter half 6, diffuser 7 and the main flow that are communicated with successively flow out pipeline 8, and the other end of throat's latter half 6 and plate-like syndeton 4 is communicated with, and described leading portion and back segment are by interlude coaxial communication.
Described throat first half 3 and throat's latter half 6 insert in plate-like syndeton 4, but throat's first half 3 do not contact with throat latter half 6, form the circular passage 9 flowing into for introducing fluid between leading portion and back segment.
Described leading portion and back segment are revolving body.
Throat's latter half 6 of described back segment inserts the degree of depth of interlude plate-like syndeton 4 and can adjust as required.
The outside of described throat first half 3 and throat's latter half 6 is all furnished with graduation mark.
Described introducing fluid inlet tube 5 is arranged on plate-like syndeton 4 bottoms.
The present invention has the following advantages: Venturi blender of the present invention can effectively improve mixing efficiency, avoids mixing uneven phenomenon and occurs; All building blocks are revolving body, easy to process; Between leading portion, interlude, back segment, for suit connects, add and make man-hour three parts axle center be positioned at same position, can automatic centering when suit, easy to assembly; Throat outside is furnished with graduation mark, and the scale that can be exposed by outside is determined the width of annular space, carries out the quantitative adjusting of width, thereby regulate the fluid introducing speed of introducing, change proportioning, improve mixed effect, increased greatly the scope of application of same venturi mixer.

Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail.
As depicted in figs. 1 and 2, a kind of Venturi blender of the present invention, comprises leading portion, interlude and back segment three parts, and described leading portion comprises the main flow flow ipe 1, contraction section 2 and the throat's first half 3 that are communicated with successively; Described interlude comprises the plate-like syndeton 4 being communicated with throat first half 3 and is arranged on plate-like syndeton 4 one end and the introducing fluid inlet tube 5 of its connection; Described back segment comprises that the throat's latter half 6, diffuser 7 and the main flow that are communicated with successively flow out pipeline 8, and the other end of throat's latter half 6 and plate-like syndeton 4 is communicated with, and described leading portion and back segment are by interlude coaxial communication.Described throat first half 3 and throat's latter half 6 insert in plate-like syndeton 4, but throat's first half 3 does not contact with throat latter half 6, between leading portion and back segment, form the circular passage 9 flowing into for introducing fluid, make to introduce fluid and can spend along this circular passage 360 inflow from different directions, effectively increased the uniformity of mixing.The plate-like syndeton of interlude, plays on the one hand and leading portion is connected with back segment and to the fixing effect of the heart, ensures that on the other hand the fluid that inlet tube is introduced can evenly carry out blending by annular space and main flow fluid.
As the preferred embodiments of the present invention, throat's latter half 6 of described back segment inserts the degree of depth of interlude plate-like syndeton 4 and can adjust as required, because the gap of circular passage can be adjusted, can change the speed of introducing fluid, to regulate the proportioning of introducing fluid flow and main fluid flow, reach desirable mixed effect, can effectively improve the mixing efficiency of venturi mixer, avoid mixing uneven phenomenon and occur.Meanwhile, the outside of throat's first half 3 and throat's latter half 6 is all furnished with graduation mark, can adjust the width of circular passage quantitatively, meets the needs under different operating modes, has increased greatly the scope of application of venturi mixer.
As the preferred embodiments of the present invention, described introducing fluid inlet tube 5 is arranged on plate-like syndeton 4 bottoms, can avoid occurring that the situation that fluid remains in plate-like syndeton occurs.
As shown in Figure 3, as the preferred embodiments of the present invention, described leading portion and back segment are revolving body, easy to process and also install time can coordinate with interlude at any angle.
