MIXING APPARATUS Filed Jan. 29, 1927 I wuentoz \I 3 Patented Jan. 28, 1930 UNITED- STATES CLARENCE J. BLEIL, OF LOS ANGELES, CALIFORNIA MIXING APPARATUS Application filed January 29, 1927; Serial No. 164,52b.

This invention is an apparatus for use in extracting oils and oleaginous constituents from seeds, sewage, and other masses of oil containing material.

One of the objects of the invention is to provide an apparatus for mixing solvent and the oil carrying material to be treated, as a preliminary step to delivering the mixture to a suitable filtering apparatus. Y The invention will be hereinafter set forth and particularly pointed out in the claims.

In the accompanying drawing:- The figure is a longitudinal sectional view illustrating the incorporator. 1 Referring to the drawing, the mixer A consists of a cylindrical casing and may be supported either horizontally or in a tilted position, but preferably slightly inclined downwardly toward the discharge end. It is divided into a plurality of compartments by baflie plates 7 0 which are staggered'so as to insure that material moving through'the casing shall be caused to travel a tortuous ath.

'Material isfed through a feed opening 1 at the top, said opening being closed by valves 72 and 73 so arranged that they may be alternately opened and closed and thereby provide for feeding the material to the incorporator without substantial loss of vacuum. Located within the compartments produced by the partitions 70 are paddles 74, mounted on a shaft 75 extending through the incorporator and driven by suitable power means, a

drive wheel 76 being illustrated for this purpose. The incorporator is provided with an end compartment having an outlet 77 which delivers the material to the pipe 11.

If for any reason discharge of the material through the outlet 77 should become temporarily arrested, it is .important to empty the incorporator, so as to prevent the solidifying of the material therein-to such an extent as to make it impossible'to rotate the shaft 75. To facilitate emptying of the incorporator under such conditions, a valve 78 is provided in one of the partitions so that a passageway may be opened alon the bottom part of the incorporator, an terial may then be delivered through the 50 pipe 79 to an emergency tank (not shown),

the ma-' and from thence forced by the pump 81 and pipe 82 to the filter, when desired. In this way the'contents of the incorporator may be emptied into the emergency tank and held until required. The emergency tank also communicates with the solvent tanks through the medium of the pipe 83 andpump D, as shown, so that solvent may be forced into the emergency tank to make its contents su'fficiently fiiiid to insure its ready flow out through the pipe 82. During the normal operation of the mixer the flow of material through the pipe 29 is prevented by means of a suitable valve. y

In practice, it is preferred to finely divide, in suitable manner, any desirable oil bearing material and to mix it with any desired quaiitity of solvent. .The mixing of the material and the solvent is effected by introducing them into the mixer at practically the same time, the solvent being intimately mixed with the oil-bearing material by reason of the agitation of the paddles 74, during the passage of the ingredients through the incorporator A. p

Having thus explained the nature of the invention and described an operative manner of constructing and using the same, although without attempting to set forth all of the forms in which it may be made, or all of the forms of its use, what is claimed is 1. Inan apparatus for extracting oleaginous constituents, a mixer comprising a closed chamber provided with staggered baffle plates, means for feeding the oil bearing material into said chamber, means for introducing a solvent into said chamber, and means for intimately mixing the solvent and thematerial and forcing said mixing means being constructed to' force said mixed materials to travel through said mixer.

2. In an apparatus for extractin bleagimeans for rotating s'ai shaft, and means for introducing the oil bearing material and a solvent into said mixing chamber, said agitators being shaped to force said material to travel longitudinally of said chamber and around the baflle plates.

3. In an apparatus for extractin oleagi- .nous constituents, a mixing cham er provided with staggered bafile plates forming a plurality of communicating chambers, a valve in one of said bafilevplates, agitators in the respective chambers for causing the material to travel in a tortuous path through the chamber, means for introducing the 'oil bearing material and a solvent in said mixing chamber, and means for operating said valve so that the material will travel in a straight line instead of in a tortuous path.

4. In an apparatus for extractin nous constituents, a mixing cham er provided with an inlet and an outlet, means within said chamber for causin themixture' to travel in a tortuous path, an means by which the mixturemay becaused to travel in a straight path to said outlet.

In testimony whereof I have hereunto set In hand.-

y CLARENCE J BLEIL.
