HEAT INTERCHAN'G-EB.

Application filed July 21, 1920. Serial No. 397,930.

To all whom it may concern:

Be it known that I, GRovER B. LANTZ, a citizen of the United States, residing at Colton, in the county ofSan Bernardino and State of California, have invented certain new and useful Improvements in Heat lnterchangers, of which the following is a specification.

to, a point of discharge, and still another object is to provide in apparatus of the i above described character, means to prevent incrustation of the surfaces with which the material comes in contact while it is being cooled or heated. o

With the above and other objects in view, all of which will fully-appear in the course of the following description, my invention consists of the construction, arrangement and combination of parts shown in the accompanying drawings in the various views of which like parts are similarly designated, and in which Figure 1 represents a longitudinal section through my improved heat interchanger; v

Figure 2, an enlarged longitudinal section of one of the end portions of the same;

is supported in a substantially horizontal position upon suitably constructed piers 0r pedestals 3.

The ends of the tubular vessel are closed by heads 4 provided with stufling boxes 5 for the passage of axially alined gudgeons 6 and 7 at the ends of a rotary container 8 of tubular form which extends within the Figure 3, a transverse section along the vessel in spaced relation to the inner cir: cumferential surface thereof.

The vessel has adjacent one of its ends an intake opening 9 and at the other end an outlet opening 10 through which the fluid by which the contents of the container are either cooled or heated, is admitted and discharged.

The gudgeons of the tubular container are fastened in plugs 12 which close the opposite ends thereof and they are supported for the rotation of the container about its longitudinal axis, in pedestal boxes 13 erected at opposite ends ofthe vessel in which the container is disposed.

The gudgeons 7 and 6 are of tubular form to serve as conduits for the ingress and egress of material to and from the container and their'ends projecting beyond the bearings, are connected respectively with relatively stationary feed and discharge pipes 14 and, 15 through the medium of,

suitable packed unions 16.

A pulley 17 mounted upon one of the two gudgeons provides a medium for the rotation of the container within the vesselby connection with a conveniently locatedsource'of mechanical energy;

Rods 18' are loosely disposed in the inlet and outlet conduits of the container and the therewith alined feed and discharge pipes to prevent incrustation of the interior surfaces of the same by solids contained in the material under treatment and they are held against longitudinal displacementby swiveled links 19 which connect their outer ends with adjacently situated parts of the stationary pipes. v

The container 8 is for the same purpose provided with a number of loosely disposed objects 20 such as balls, pebbles or rods, which during rotation of thecontainer have a grinding and scouring'action upon its interior surface and thereby prevent the deposit and adhesion of incrustive matter.

Blades 21 projecting radially from the cylindrical wall of the container into the surrounding space'of the cylindrical vessel are adapted to agitate the fluid by which the material under treatment is cooled or heated, for the purpose of maintaining a uniform temperature.

In the operation of the machine'the ma-J terial to be cooled or heated is fed through the pipe 14 and the conduit"? into the container 8 and during its passage therethrough from one end to the other is subjected to the influence of a fluid of difierent temperature Which is introduced into the vessel 2 through the intake opening 9 thereof.

The two fluids are discharged from the container and the vessel respectively through the conduit 6 and the outlet opening 10 so that subject to a continuous teed thetwo fluids Will flow constantly in opposite directions and by their contiguity interchange their temperatures to the desired degree.

The rotary motion of the container sub jects every part of the material repeatedly to the heating or cooling influence of the surrounding fluid and to some extent prevents subsidence of solids in the material and subsequent inc'rustation of the surface to which it settles.

The movements or" the balls or other objects in the container and of the rods in the ingress and egress conduits of the same are, however, theprincipal factors in preventing the i'ncrustation of the surfaces With which the material is in contact, by their abrasive action during the revolving motion of the parts of the rotary elem int in which they are disposed.

The apparatus as hereinbefore described is suitable for either cooling or heating any fluid material, be it a liquid, solid, vapor, gas or acombination of any tWo or more thereof, and the medium by which the material is cooled or heated may be a liquid, vapor or gas or combination of either two or all of these fluids,

The blades on the rotary container er:- tending into the surrounding space of the vessel agitate the fluid in said space for the purpose of keeping it at a uniform tempera ture which especially in the use or" a liquid is essential to maintain the effective influence of the fluid upon the material throughout the length of the container.

By corrugating the cylindrical Wall of the container as shown in Figure 5 of the drawings, incrustation thereof may be prevented to a considerable extent with or Without the use or balls or" other abrasive" objects, and I desire it understood that other changes in the construction of the parts of the apparatus may be resorted to menses Without departing from the spirit of my invention defined in ti hereunto appended claims.

The vessel in which the container has its movement be made in the form of an open trough when the apparatus is used cooling the material by the use of a liquid, the cross-sectional form of the vessel may be varied from that shown in the drawings, and the vessel may be mounted for rotation and connected with a driving element to move simultaneousl With the container in either the same or the opposite direction should the i ature of either of the two fluids demand a movement of this hind for the operation the machine at or near its point of ma Illlltllll e'fliciency.

Haring thus described my invention What I claim desire to secure by Letters Patent is:
