Abstract
The utility model discloses a venturi mixer for introducing rotatably. The venturi mixer for introducing rotatably comprises a front section, a rear section and a middle section which is coaxially communicated with the front section and the middle section; the front section comprises a mainstream flow-in pipeline, a contraction section and a throat part front half section which are communicated sequentially; the rear section comprises a throat part rear half part, a diffusion part and a mainstream flow-out pipeline which are communicated sequentially; the middle section is a casing pipe; the throat part front half part is inserted into the casing pipe and is fixed; the throat part rear half part is inserted into the casing pipe and enables the rear section to rotate in the casing pipe; the throat part front half part and the throat part rear half part are not in contact in the casing pipe; a discoid connecting structure is sleeved on the surface of the throat part rear half part, so that the rear section can rotate in the discoid connecting structure; one end of the discoid connecting structure is provided with an introduced fluid introducing pipe communicated with the discoid connecting structure; an annular channel in which an introduced fluid is introduced is formed in the discoid connecting structure; a round hole which equivalently enables an introduced fluid to be introduced in a single-point mode is formed in the throat part rear half section. According to the utility model, the fluid is introduced into the venturi throat part in a rotary input mode instead of a single-point input mode, and the mixing efficiency is improved.
Description
Technical field
The utility model relates to venturi mixer technical field, is specifically related to a kind of venturi mixer that rotates introducing.
Background technology
Venturi mixer be a kind of in engineering reality gas-liquid or the liquid liquid mixing arrangement of extensive application.The classical venturi tube of common venturi mixer Wei Yige throat perforate, main flow fluid is by flowing through in classical venturi tube, introducing fluid flows into through perforate, thereby make two kinds of fluids produce certain impact grinding effect because pressure changes, and the turbulent flow that utilizes two kinds of high-velocity fluids to form reach the object of mixing.At traditional venturi, introduce in structure, because fluid-mixing strength of turbulence is little, easily cause and mix the problems such as inhomogeneous and mixing efficiency is low.
Summary of the invention
In order to solve above-mentioned problems of the prior art, the purpose of this utility model is to provide a kind of venturi mixer that rotates introducing, makes venturi throat introduce fluid and becomes rotation input from single-point input, improves the mixing efficiency of venturi mixer.
In order to achieve the above object, the utility model adopts following technical scheme:
A kind of venturi mixer that rotates introducing, comprise leading portion, back segment and by the interlude of leading portion and back segment coaxial communication, described leading portion comprises the main flow flow ipe 1 being communicated with successively, contraction section 2 and throat's first half section 3, described back segment comprises the throat's second half section 5 being communicated with successively, diffuser 8 and main flow flow out pipeline 9, described interlude is sleeve pipe 4, described throat first half section 3 is inserted in sleeve pipe 4 and is fixed, described throat second half sections 5 insert in sleeve pipe 4 and make the described back segment can be in the interior rotation of sleeve pipe 4 under the effect of external force, described throat first half section 3 did not contact in sleeve pipe 4 with throat's second half section 5, on the surface of described throat second half section 5, cover has plate-like syndeton 6, and described plate-like syndeton 6 and throat's second half section 5 are for loose fit, so that described back segment can be in the interior rotation of plate-like syndeton 6 under the effect of external force, in one end of described plate-like syndeton 6, be provided with the introducing fluid inlet tube 7 with its connection, in described plate-like syndeton 6, form the circular passage 10 flowing into for introducing fluid, on the described throat second half section 5, have one and make to introduce the circular hole 11 that fluid single-point is introduced.
Described introducing fluid inlet tube 7 is arranged on the bottom of plate-like syndeton 6, makes to introduce fluid and introduces from the bottom of plate-like syndeton 6.
Described leading portion and back segment are revolving body.
The utility model compared to the prior art, has the following advantages:
The venturi mixer that the utility model rotation is introduced 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 during suit, easy to assembly, under the effect of external force, make the rotation of blender back segment, when throat's second half section rotates, circular hole 11 on throat's second half section 5 rotates thereupon, thereby make the introducing fluid of different directions in circular passage 10 enter throat's second half section 5 by circular hole 11, make the single-point input of introducing fluid become 360 degree rotation inputs, strengthened the mixing of introducing fluid and main fluid, while having avoided single-point to introduce, introduce the problem that fluid only concentrates on conduit upper, make to introduce fluid and be better full of whole pipeline, obviously improved mixed effect, effectively increased the scope of application of same venturi mixer.
