FLUID MIXING APPARATUS Filed Aug. 14, 1957 j j j jj 2*1 54 I N VEN TOR. Z4 WL'ZZL'@ W wl/de@ BY Man/LL'dC/y, Dwz [els CQ Marc/i TTRNEYS Patented Jan. 10, 1967 This invention relates to means for mixing fluids, and more particularly to a chemical fluid mixing apparatus by which various chemical uids may be mixed or commingled with each other.
An object of the invention is to provide `a novel and improved apparatus for mixing a number of chemicals, such as chemical fluids, which is extremely simple in its construction, and effective and foolproof in its operation.
Another object of the invention is to provide a novel and improved mixing apparatus as above set forth, wherein an orifice-containing, jet-type injection head is provided, disposed in a stream of fluid, said head being arranged to automatically clear itself or prevent fouling when the openings thereof tend to become clogged with particles.
Yet another object of the invention is to provide an improved fluid mixing apparatus in accordance with the above, w-herein complete commingling or mixing of several uids is effected without the use of movable parts, such mixing utilizing the ilow or movement of the fluids, instead. v
A feature of the invention resides in the provision of -an improved, clog-resistant orice means in a mixing apparatus, which means is of extremely simple construction while at the same time being reliable and effective in its operation.
A still further object of the invention is to provide an improved fluid mixing apparatus Ihaving all of the above features and advantages, while being nevertheless easy and economical to manufacture, and reliably operable throughout an extended period of use without requiring attention or servicing.
Other features and advantages will hereinafter appear.
In the drawings accompanying this specification, similar characters of reference indicate corresponding parts wherever possible in the several views, in which:
FIGURE 1 is a view partly in yaxial section and partly in elevation, of an improved uid mixing apparatus made in accordance with the invention.
FIGURE 2 is a view partly in elevation and partly in transverse section, the section being taken on line 2-2 of FIGURE 1.
FIGURE 3 is a front and elevational view, enlarged, of the discharge orifice means of the injector tube of the apparatus.
FIGURE 4 is a transverse sectional view taken on line 4-4 of FIGURE 3.
Referring to FIGURE l, the improved fluid mixing apparatus shown therein comprises an elongated, tubular mixing chamber adapted to have a primary fluid flow through it from left to right, as indicated by the arrows 11.
Disposed within the chamber 10 are means by which opposite, swirling movements are imparted to the uid passing through the chamber, said means comprising a plurality of successive members 13 spaced longitudinally of the chamber 10 and extending across the passage provided t-hereby. Each member 13 comprises a plurality of plates or vanes 15 extending radially outward from a central point or portion 16 of the member, said vanes being angularly disposed in the manner of propeller blades, by which uid striking the vanes will have imparted to it a swirling movement. Also, in accordance with this invention, each succeeding swirling means is arranged to reverse the swirling movement imparted to the uid by the preceding means, this being accomplished by opposite slopes given to the sets of individual vanes.
Thus, in accordance With the invention, the opposite swirls imparted to the luid and the substantial turbulence and agitation resulting therefrom effect a complete mixing or commingling of all constiutents of the fluid stream.
Ahead of the air swirling means 13 I provide a uid injector tube 20, said tube passing through a side wall 21 of the mixing chamber 10 and at its inner end having a laterally-extended, nozzle -portion 22 directed against the intended flow of fluid in the mixing chamber 10 as indicated by the arrows 11.
Moreover, in accordance with this invention, I mount on the discharge nozzle 22 a novel and improved, orificeproviding means 24 adapted to be self-clearing. That is, the orifice-providing means 24, in response to pressure wit-hin the discharge nozzle 22, may distort and cause an enlargement of the orifices thereof, so as to dislodge and dispose of particles or obstructions which might become lodged in said orices.
Referring to FIGURES 3 and 4, the orifice-providing means comprises a flexible diaphragm 25 which is preferably of conical shape, having a mounting flange or rim 26 adapted to encircle and grip the discharge nozzle 22 for supporting the diaphragm across the end thereof. The diaphragm 25 has a plurality of annular, flexible portions 27 defining discharge orifices, ve such portions being illustrated in FIGURE 3. Each of the orificedening portions 27 is adapted to deforrn or stretch in response to increased pressure in the discharge nozzle 22, such as might occur if the orices should become clogged with particles of dirt, or chemical particles. Upon such enlargement occurring, the dirt or chemical particles will be forced through the orifices, thereby clearing t'he same and permitting the intended and proper operation of the discharge nozzle.
For the purpose of introducing a chemical fluid into the injector tube 20 I provide a branch tube 30 secured to a side wall of the injector tube and extending laterally from the latter, said branch tube being connected with a suitable type of chemical pump 32, as indicated in FIG- URE 1. Also, for the purpose of facilitating the intermixing of the chemical fluid supplied to the injector tube 20 with the primary uid owing through the mixing chamber 10, I provide a compressed air tank 34, attached to the injector tube 20 and adapted to force compressed air therethrough, for discharge from the nozzle 22.
In accordance with the above construction, chemical fluid which is introduced into the injector tube 20 from the pump 32 will mix with the compressed `air passing through said tube, and the mixture will be discharged from the nozzle 22 in a direction opposite to the flow of -primary uid through the mixing chamber 10. There will ensue a mixing and commingling of the two fluids and also the compresesed air, and such mixing will be facilitated by the oppositely-acting, swirling means 13, whereupon a complete `admixture of the uids will occur.
It will be readily observed that, aside from the components of the pump 32, there are no movable parts in my mixing apparatus which may become inoperative due to corrosion or other factors, yet a complete and effective mixing of fluids is had. Moreover, the construction and yassembly of the various components are simple, and the manufacture of the apparatus may thus be economically carried out.
Variations and modifications may be made within the scope of the claims, and portions of the improvements may be used without others.
I claim:
1. An apparatus for mixing chemical uids, comprising an elongate, tubular mixing chamber of substantially constant cross-sectional area, adapted to have uid ow through it under pressure axially in a predetermined direction, said chamber having relatively smooth inner walls; a plurality of stationary means disposed in succession within said chamber at different, longitudinallyspaced locations, to divide said chamber into a plurality of compartments, and each of said means being engaged with said inner walls for support thereby and being formed to impede the ow and impart a swirling rotative action to the uid owing through said chamber, each succeeding one of said means reversing the direction of action of the swirl of the fluid caused by said preceding means, whereby each compartment comprises a separate mixing area in which a turbulence of the mixing fluids is set up which is different from that in the preceding or succeeding areas, a fluid injection tube extending into said mixing chamber ahead of said duid-swirling means, having a discharge nozzle in the chamber directed axially of the chamber and generally against the direction of the intended flow of fluid through the chamber, said discharge nozzle having a plurality of inclined orices disposed about a central point and directed angularly outward of the axis of the mixing chamber in divergent directions and angularly toward the said smooth inner walls; and means disposed exteriorly of the mixing chamber, for forcing a chemical ilud under pressure into said injection tube.
