The present invention relates to anim-.
proved fluid mixer and more particularly to mixers used for mixing li uids.
The general purpose my, invention is the provision of a simple and inexpensive mixer of this character that will thoroughly mix the fluids and bring them into intimate contact in a finely divided state.- Other purposes. are the provision of a mixer capableof tibating large quantities of fluids economv deal] and resisting any corrosive action of the uids. I
My invention resides in a mixer comprising a closed vessel having an'inlet in the lower portion for the entrance of the fluids,
fluid mixing and a 'tatin means within the vessel and a fluid out at f in the upper portion of the vessel. Y
- Morev particularly my invention resides in a mixer of the type referred to in which the mixing and agitating means within the vessel comprises a ropeller ositioned ad- 'acent the liquid in et and a apted to vioently a' itate the liquids and pro el them upwar y vanes-pro ecting from t e inner walls of t e vessel in the path of the liquids,
' and a perforated plate positioned in the path of the liquids above the vanes.
' This invention is articularly ada ted for use in the process 0 puriYing cru e oil or distillates by treatment wit sulfuric acid in connection with'which, for 'clearness in explanation, it will. be described, it being understood that my invention is in no way I limited to such a use, and it is obvious that many other applications of the mixer are possible.
In the urification process referred to sulfuric acid is introduced into the-crude oil 40 'or distillate after which the mixture of-the two fluids is agitated or stirred in some form of mixer. The effectiveness of the purity ing reagents apparently is largel dependent upon the intimacy of the contact between the two fluids resulting from this mixing operation. After completion of the mixing operation the mixture is drawnofl, and the acid sludge containing the impurities separated from the purified distillate. The mixers used heretofore have been unsatisfactory in that this mixing process was incomplete, re-
sultin in a product less pure and the use of a arger and more concentrated amount of the acid reagent than is neeessary in a of the sha mixer constructed according to I my inventron. The means b which the above desired results are attaine will be fully understood by a consideration of the following -descrip-- t1on and accompanying drawing, in which Fig. 1 1s a central vertical section; and
'Fig. 2 is ahorizontal section on plane 2-2- of Fig. 1.
" The container 'or mixing chamber com prises a cylindrical section 1 the ends 'ofwhich are closed by heads 2 and, 3. The
heads are secured to'the cylindrical portion jects through the upper head and a bracket 15 attached to its upper face.
The upper by pipe flanges 11 and 12. Centrally arend of the shaft is fitted with a bevel pin- I ion 9. meshing with a corres ondin inion 10 attached to a driving sha 8. in; convement source of-power may be used to 'drive the mechanism, a pulley 16 for a belt illustrated. -The lower portion 4 1s fitted with stirring blades forming an agitator or propeller 5. This propellen is preferably constructed with a pitch giving 1t,an upward thrust. An inlet 6 is provided in the lower portion of the cylinder 1 directly opposite this propeller for a purpose that will appear later.
Inwardly extending vanes 19 are dis posed on the walls of the cylinder in sub stantially radial relation to the central shaft, w th their upper ends extending inwardly into proximity to the shaft. number of these vanes may be used but four placed at right angles to each other have been found to be efiective in practice. A perforated late 17 surrounds the shaft and 1s supporte in a horizontal position drive being the construction material used may-be va ried within wide limits. In practice a mix- In the operation of the device theoil'and ref- T erabl by means of the vanes 19 and slight ly be ow the outlet 7. The proportions and The c linder,-vanes, heads and Any" um ing cylinder 2 ft. by 10 in. has been used,.
acid in the requisite amounts are introduced through pipe 20 and pipe 21, respectively, preferably under pressure, by way of the pipe 18, so as to force them into the path of the revolving propeller. The resulting swirl of liquid is agitated and broken up by being thrown against th e vanes, 1n the course of which the acid and crude 011 or distillate are thoroughly mixed and brought into contact in a. finely subdiv ded condition. The liquids are further mixed by passage through the apertures in the perforated plate, after which the mixture issues from the mixer through the outlet 7 ready for further treatment. A simple unit of this kind treats continuously several hundred barrels per day. I Due to the more intimate contact effected between the l1quids, it has been found possible to use dilute in place-of the customary concentrated acid, thereby cheapening the process and also making the acid sludge by-product thinner and more valuable. 'Previous mixers have been devised in which propellers, vanes, perforatedplates, and other like elements were used, ut my new arrangement comprising the above described elements in the particular cooperative relationship rei paaaa'r i' container having a fluid inlet and an outlet in the bottom and top portion thereof, re-
spectively, a stirring device mounted wlth in the conta'iner adjacent the inlet, inwardly pro ecting'vanes supported from the inner wall of the container, and a perforated plate disposed within the container in a substantially horizontal plane intermediate the outlet and the vanes.

In testimony whereof, I afiix my signature.
