Specific implementation mode
The present invention provides a kind of venturi type mixer, for make the purpose of the present invention, technical solution and effect it is clearer,
Clear, the present invention is described in more detail for the embodiment that develops simultaneously referring to the drawings.It should be appreciated that specific reality described herein
Example is applied only to explain the present invention, is not intended to limit the present invention.
It please refers to Fig.1 to Fig. 6, the present invention provides a kind of venturi type mixer.In order to make it easy to understand, using dotted line in Fig. 1
The position of inner tube is schematically depicted, but inner tube can not be observed directly from outside.Dotted arrow is illustrated as first in Fig. 4
Fluid, solid arrow are illustrated as second fluid.Attached drawing is only used for explaining the structural principle of the venturi type mixer, not with
Actual product is proportional.
The venturi type mixer includes sequentially connected contraction section 1, trunnion 2 and expansion segment 3, and the trunnion 2 wraps
The outer tube 21 being coaxially disposed and inner tube 22 are included, the both ends for the inner cavity that outer tube 21 and inner tube 22 surround are respectively arranged with one piece of annular
Plate 4（That is, the both ends of the inner cavity are not in communication with the outside）, the outlet end of contraction section is welded with that corresponding block annular slab, is expanded
The input end of section is welded with that corresponding block annular slab, so that inner tube 22 is connected to contraction section 1 and expansion segment 3 respectively.Outside
An at least inlet tube 7 is provided on pipe 21；There are one air deflector, the air deflector includes a mandrel for 22 settings in inner tube
51, which is coaxially disposed with inner tube, circumferentially equiangularly disposed on the outer wall of mandrel 51 to have N blocks fin 52；Inner tube 22
Tube wall on circumferentially angularly offer N row through-hole 221, each column through-hole is respectively directed between adjacent two pieces of fins（Such as Fig. 3
It is shown）；The N is the integer more than or equal to 3.Above-mentioned outer tube and inner tube are preferably welded with that corresponding block annular slab respectively
Connection.
In actual use, first fluid passes through from the input end of contraction section and successively inner tube；Due to the mandrel of air deflector
The guiding of blocking and each fin, therefore first fluid is uniformly spaced into N strands of first fluids in inner tube；And second
The inner cavity that body enters outer tube from inlet tube and inner tube surrounds then passes through the N row through-hole in inner tube and enters inner tube, i.e. second
Body is divided into N row second fluids, and each row second fluid is just against one first fluid, therefore first fluid and second
Fluid can be sufficiently mixed in inner tube, disclosure satisfy that two kinds of fluids（Such as chlorine and propylene）Mixing after react rapidly want
It asks.
Specifically, same referring to Fig. 6, each column through-hole respectively includes multiple through-holes 221 along inner tube length directional spreding
The spacing of two through-holes 221 of arbitrary neighborhood is equal in row through-hole；Each through-hole is equal sized.Setting is so that in inner tube in this way
Through-hole setting is uniform, and the specification of each through-hole is identical so that second fluid can uniformly across inner tube tube wall simultaneously
Into the inner cavity of inner tube to be mixed with first fluid.
Further, as shown in figure 5, each through-hole 221 is the small taper hole of outer imperial palace." outer imperial palace is small " refers to cone herein
The bigger diameter end in hole corresponds to the outer wall of inner tube, and the miner diameter end of taper hole corresponds to the inner wall of inner tube, and such setting is so that second fluid is logical
It is in acceleration mode when crossing each through-hole, is conducive to two kinds of fluids and mixes rapidly.
Into one, referring to Fig. 5, the cross section of every piece of fin 52 is isosceles triangle, and the bottom edge of isosceles triangle
It is connect with mandrel, that is, the bottom edge of isosceles triangle corresponds to the root of fin.It is understood that for the ease of connection, every piece of fin
The bottom edge of piece can be arranged to have and the matched radian of mandrel.Such setting makes the space phase in inner tube at mandrel
To smaller, and relatively large far from the space at mandrel, therefore per one first fluid close proximity to through-hole, it is convenient for and second
Body mixes.Preferably, the length of mandrel is equal to or the slightly short length with inner tube.
Preferably, as shown in Figure 1, being connected with 4 inlet tubes 7 on outer tube（Only observe 3 inlet tubes in the visual angle of Fig. 1）,
In the projection perpendicular to the plane of outer tube, the angle between any adjacent two inlet tube is 90 degree.Setting is so that the in this way
In the cavity that second-rate body can enter outer tube with ground and inner tube surrounds.
Preferably, every inlet tube 7 is respectively positioned on the middle part on 21 length direction of outer tube, and first fluid enters outer tube and inner tube
It can be evenly distributed rapidly in circumferential direction and length direction after in the cavity surrounded.
Further, for the ease of the connection with external pipe, the input end of every inlet tube 71 is connected separately with one piece
Flange 71.
Preferably, the N is equal to 16, which can either play the role of subdivision, and first fluid is divided into 16 strands, will
Second fluid is divided into 16 row, improves the uniformity of mixing, while ensureing that difficulty of processing does not improve significantly.
It can be to be integrally formed when actual fabrication, between fin 52 and mandrel 51, can also be to be welded to connect.
Further, in air deflector 3 be welded to connect between fin and inner tube.That is, after air deflector is fitted into inner tube, and adjust
It, only need to the fixation of air deflector can be realized in the spot welding between inner tube respectively by the both ends of three fins after whole angle（Not
It needs all to weld 16 fins with inner tube）, reduce the workload of welding.Preferably, be used to weld with inner tube 3
The angle between any two fin in fin is 120 degree, to ensure the stability of connection.
It should be noted that the venturi type mixer of the present invention is essentially consisted in components such as trunnion and air deflectors
Improvement, therefore do not limit the features such as the concrete structure of contraction section and expansion segment, size.In addition, in practical application, the contraction
The components such as section, expansion segment, trunnion, air deflector are usually that carbon steel or stainless steel are made, and service life is long, and the institute of the present invention
The venturi type mixer stated mainly for the treatment of non-corrosive fluid, therefore venturi type mixer during one's term of military service not
Air deflector is needed replacing, therefore, by being welded to connect, can will save cost of manufacture between contraction section, expansion segment, trunnion, also make
It is compact to obtain venturi type mixer structure.
It, can according to the technique and scheme of the present invention and its hair it is understood that for those of ordinary skills
Bright design is subject to equivalent substitution or change, and all these changes or replacement should all belong to the scope of protection of the present invention.
