JOHN JOHNSON, 0F BROOKLYN, NEW YORK.
RAPID DISSOLVER.
Specificationof Letters Patent. Patented Sept 21 1920 Application filed February 21, 1919. Serial No. 278,469.
To all whom it may concern:
Be it known that I, JOHN JOHNSON, a citizen of the United States, residing'at Brooklyn, New York, have invented certain new and useful Improvements in Rapid Dissolvinvention consists in the location of a tur bine mixer in the bottom of a tank of pref-- erably cylindrical form, and the provision of aseries of pockets or sluiceways situated about the circumference ofthe tank and so shaped and'arranged that substantially all of the fluid flowing from the turbine is directed along the sluiceways. Another important feature of my invention consists in the arrangement of the-sluiceways so that the fluid passes along their entire length at substantially the same velocity as that'given to it on leaving theturbine mixer;
In order that the substances to be dissolved may always .be directed into the sluiceways when dropped into the mixing tank, Iprovide partitions having sloplng I sides.
Other objects and important features of the invention will be apparent from the following description and claims when taken in connection with the accompanying drawings, in which Figure "1 is a part sectional and part elevational View of one form of my improved rapid dissolving device;

To produce circulation of the fluid used as the dissolving agent, I provide a turbine mixer or impeller 2 which may be of any desired construction and which may advantageously be of the construction shown and described in application Serial No. 278,467,
filed February 21, 1919.
As described in the said application, the turbinemixer is provided with a series of curved blades 4 shown in dotted lines, Fig. 2, said blades acting, when the turbine is rotated, to produce a tangential flow of the liquid from the turbine.
In the form-of'device shown in Fig. 1, I have provided means, which may advantageously be the same as that shown in my application above referred to, for changing the tangential direction-of flow of the liquid I from theturbine into a flow in aradial direction across the bottom of the tank 6. These means, as described in said application, mav comprise a ring of curved deflecting blades 8 which are so situated with re-v spect to the turbine blades that the liquid as it comes from the turbine is changed in direction and flows radially acrossthe bottom of the tank. In order to produce a smooth flow of liquid to. the turbine and'prevent eddies in the stream flowing downwardly toward the turbine, I may also advantageously use a centripetal member 10 which maybe formed substantially like that disclosed in my application abovereferred to. The member 10 and turbine'2 maybe cast in one piece and may be connected to a shaft 12-, which shaft may be driven through suitable gearing 14 and 16 connected to a powershaft. 18, all as set forth in detail in my application above referred to.
present invention relates more par-' My ticularly to the provision of means for producing a rapid rate of disintegration of solid substances by the dissolving fluid set in motion, by the turbine.
' A tank 6, circular in cross-section, has a series of partitions 20 arranged about the inner circumference thereof, the partitions being triangular in cross-section where they meetthe walls of the tank. In the form of the device shown in Figs. .1 and 2, the bases ,of 'the partitions form isosceles triangles,
,and the angle at the apex of each triangle substances dropped into the tank will slide may be such that the sides of the adjacent triangles are parallel, these sides :forming sluiceways through which the liquid from the turbine flows. The sides of each partition slope upwardly and meet in a'dihedral angle. With the partitions thus shaped, any
' down the sides and 'into the sluiceways where they will meet with a rapid current of disof the contents of the mixer in the direction- The combined ter.
way at that point.
solving fluid coming from the turbine mixer.
The sides of each of the sluiceways may also be parallel to a radius passing midway between them so that the flow of liquid coming from the deflecting blades '8 passes directly into said sluiceways withoiit any tendency to create eddies in the stream and also without any tendency to create a general rotation of movement of the turbine. width of the sluiceways is about equal to the circumference of the deflecting blade rin '8 and therefore substantially all of the issolving liquid leaving the turbine passes up the sluiceways.
In the form of device shown in Fig. 1. the
partitions are triangular in cross-section throughout, but in'order to provide. for an equal velocit of flow of liquid from the turbine throug out the entire length of the .sluiceway, I may make the sides of each partition vertical for a distance equal in,
height to the depth of the turbine 2. This form of partition is shown in Figs. 3 and 6.
I may also use the form shown in Fig. 8 wherein the nose of the partition has flat sides for-a part of the distance only. This form prevents the formation of a corner at m, Fig. 8, which might accumulate solid mat- In the form of device shown in Figs. 6 and 10 inclusive, I am enabled to dispense with the use of the deflecting blade ring 8,.
as shown in thefform of device heretofore described, by forming the partitions in such a way that the sides of adjacent bases may be parallel and'so that one side is substantially tangential to the periphery of the turbine. I may use the turbine 2 and centripetal member 10 of thesame form as that shown in Fig. 1 and described in my application above referred to, but in this form of device I do not use the deflecting'blades 8 conditions imposed upon them, the base triangles being no longer isosceles. The genleaving the turbine, up the sides of the tank and back to the turbine. No eddies are produced in the tank and in practice it is found that the dissolving action is about three times as rapid as in forms of device previously used. Q
