MIXING NOZZLE.

Application led March 7,1927. Serial No. 173,309.

The invention relates to mixing nozzles, and particularly to nozzles for use inmixing oil with acid, although the nozzle is useful in other relations, wherein it is desirable to secure the intimatemixture of two or more liquids as they pass through a conduit. In the treatment of oils with acid, allalies, or other chemicals to remove sludge and impurities, it is necessary to secure a very intimate mixture of the oil and acid before they receive their alkaline treatment to neutralize the acid, and the present inven tion has for its primary objects theprovision of a simple nozzle construction which will give a very thorough mixing of the oil and acid. One embodiment of the invention is illustrated in the accompanying drawing, wherein Figure 1 is a vertical section through a pipe with two of the mixing nozzles mounted therein. Figs. 2' and 3 are sections von the lines II-II and III-III of Fig. 1. .And Fig. l is a section through a modified construction.

Referring to the drawing, 1, 2 and 3 are pipe sections provided with opposing pairs of flanges Ll, lsecured by the bolts 5. Two of the mixing nozzles are shown, but it will be understood that any number maybe used in series, or that-'a single one may be used, depending upon requirements.

The nozzles are cast of any suitable material, preferably of high corrosion resisting composition, such as high silicon ir0n,or a copper, aluminum, iron alloy, such as that known under the trade name of Alcumite. The casting comprises what may be termed an inlet portion A and a mixing portion B with a flange 6 clamped between the pair of opposing pipe ends. 1

rlhe inlet portion A fits easily in the pipe at 7, and rearward therefrom tapers to the left,` as shown, with the inclined inlet passages 8, 8 and a. central passage 9. Interiorly the inlet passage tapers to the right, leading at it-s reduced forward end into the mixing portion B. A pair of partitions 10 divide the main inlet passage into four parts, as indicated in Fig. 3.

The mixing portion B consists of a cavity 11 having its front wall provided with the four openings 12, 12, 12, 12 (Fig. 2), the central portion of such wall being provided with the cone 13.

Iihe liuidsto be mixed, vflowing to the right through the pip-es 1, 2 and 3, enter the openings 8 and 9, and are vbroken into a.

plurality of streams by the partitions 10, 10 (Fig. 3)', rwhichr are brought together in the tapering forward end of the inlet passage, andY discharged into the cavity 11 at an increased velocity. Four streams are. formed at this po1nt,.due to the partitions'- nozzle 16 on a line corresponding in locaf tion to the line II`II of Fig. 1. This nozzle is like that of Figsgl to 3, except that the front wall of the mixing chamber is provided with only two openings 14, 14

instead of the four openings 12, 12, 12, 12` 'H of the Fig-. 1 construction, and except that the wedge 15 is substituted for the con-e123vk of Fig. 1. In the longitudinal section, this nozzle is substantially the same as that shown in Fig. 1. The nozzle is capable of other modifications without departing from the broad invention involved.

lVhat I claimis:

1. The vcombination with a pipe through which fluids to be mixed are circulated, of a nozzle-mounted in the pipe having an inlet portion with its passage tapering inwardly in the direction of flow of the fluid, and having a mixing portion into which the reduced end of such inlet portion discharges, said mixing portion comprising a cavity having a forward wall, the central part of said forward wall beingv in line with said reduced end and imperforate and with outlet passages outward from such central part.

2. The combination with a pipe through which liuids to be mixed are circulated, of a nozzle mounted in the pipe having an inlet portion with its passage tapering inwardly in the direction of flow of the fluid, and having a mixing portion into which the reduced end of such inlet portion discharges, said mixing portion having a forward wall in lint .lill

with the center line of said reduced end provided With a cone fordefleeting the fluid outwardly from said center line, and said Wall also being provided with a plurality ot discharge openings surrouudinel said cone..

3. The combination -ivitli a Apipe through which fluids to he mixed are circulatefil, ol' a nozzle mounted in the pipe having an inlet portion With its passage tapering` inwardly in the direction of flow o'l the fluid, and han ing a mining portion into which the reduced end of such inlet portion discharges, said mixing portion comprising a cavity having' a forward Wallin line `with said reduced end provided with a member et wedge cross section, and alsoprovided With a pluralit,7 of outlet passages outward 'from said ineinloer.

l. The combination ivith a pipehaving; opposed tlanged ends and means tor securing; them together, ot a nozzle in 'the pipe having` a tlangeclainped between said tlangcdlpii'ie ends, 'and having an inletfportion tapering,Y inward `inthe direction of flow ot 'the liquid and a mixing portion comprising a ravitv with a -front Wall having an inipei''oi'ate central Vportion and ivith outlet passages out- Ward of said central portion. i

5. The combination with a pipe through which iluids to he mixed are circulated, ot a nozzle mounted inthe pipe having" an inlet portion With itspasgage tapering1 inwardly in the direction of flow ot the fluid, and havinga mixing portion into which the reduced end of such inlet "portion discharges, said mixing portion comprisinga cavity v'ith a front Wall having'` an iinperiiorate central portion and with outlet passages outward ot said central portion and said inlet portion vhaving; its rearward exterior surface tapering," to the rear and having, a central inlet passage and a` plurality ot' inclined inlet passages leadingf 'troni said `exterior surface to said inlet. passage. t

G. The combination with a pipe through which fluids to he mixed are circulated, of a nozzle mounted in the pipe having` an inlet portion with its passage tapering inwardly` in the direction oi' flow of the fluid, and having` a. mixing portion into which the reduced end ot such inlet portion discharges, said mixing portion comprising a cavity With a front Wall having` an iinperforate central portion and With outlet messages outward ot' said central portion, anc said inlet, intermediate its ends, havingthe exterior surface in proximity to the interior oi" the pipe, and having such exterior surface taperinr to the rearand havingl a central inlet passage and a pluralityT ot inclined inlet passagesleading troni lsaid exterior suri'ace to said inlet pas`- sage. t 7. The combination With a pipe through which 'fluids to be mixed are circulatefil, ot a o. JAooBsnN.
