EVAPORATING-TANK.
Specification of Letters Patent.
Patented Feb. 19, 1918.
Application filed April 13, 1916. Serial No. 90,811.
[0 all whom it may concern:
Be it known that I, \VILLIAM E. Fm-rronnn, a citizen of the United States, residing at Tamaqua, in the county of Schuylkill and State of Pennsylvania, have invented certain new and useful Improvements in Evaporating-Tanks, of which the following is a specification.
This invention relates to an evaporator which i intended for heating, concentrating or evaporating all kinds of liquids Or for the heating or drying of air 01' other gases, fluids or other materials.
It is well known that certain strong solu tions when treated in an evaporating pan have a tendency to corrode steel, brass, wrought iron and other material to a much greater extent than cast iron. The latter material by reason of its resisting qualities and cheapness is advantageous to use, but it presents its own difficulties in the way of securing quick assemblage and accessible and tight joints, and of permitting necessary ex-.
pansion and providing for necessary pressure resistance.
The object of the present invention is to provide a form of evaporator in which a cast iron pan and spur tubes can be employed, and in which the tubes can be easily and quickly assembled and detached for repairs, and in which tight joints will be provided in exposed or accessible position so that their condition can always be noted, and in which the pressure is borne almost completely by the tubes and is not transmitted in any appreciable degree to the walls of the pan.
With the foregoing and other objects in view which will appear as the description proceeds the invention resides in the combination and arrangement of parts hereinafter described and claimed and illustrated in the drawing. It being understood that changes in the precise embodiment of invention herein disclosed can be made within the scope of the claims and as indicated by the variations in the diflerent claims without departing from the spirit of the invention. Moreover, while it is preferred to employ cast iron, it will be understood that any other suitable material may be used.
In the accompanying drawings forming part of this specification.
Figure 1 is a vertical section through an evaporator constructed and arranged in accordance with the present invention, showing the spur tubes in elevation;
Fig. 2 is a plan view thereof, partly broken away; and
Fig. 3 is an enlarged vertical section through part of the pan and one of the spur tubes and bleed pipes.
Like reference numerals indicate corre sponding parts in the different figures of the drawing. V
The evaporator of this invention comprises a pan 1 having an upper flange 2 and an outlet?) provided with a flange 4. Extending along each end of. the pan 1, adjacent the bottom thereof is a series of ports or openings 5, each provided with a flange 6 on the outside of the pan. The parts so far described may if desired be all cast in one piece as shown.
Removably extendingthrough each of the flanged ports 5 is a spur tube 7 having at its outer end an annular flange 8. By spur tube I mean a tube having a closed inner end. It will be seen that the tubes at opposite ends of the pan are preferably set in line with each other; their inner ends being slightly spaced apart so as to allow for ex pansion and contraction.
Set against the flange 8 of each spur tube 7 is the flange 9 of an elbow 10. The flanges 6, 8 and 9 in practice are bolted or otherwise detachably secured together in any desired manner.
Extending through the outer wall of each elbow 10 is a threaded or other suitable port 11 into which is screwed or otherwise detachably secured a bleed pipe 12 having its inner end open. An escape cock 13 is arranged at the outer end of each bleed pipe 12. By opening the cock 13, trapped air or other fluid may be bled from the inner end of the spur tube whenever necessary.
Each of the elbows 10 at its lower end is provided with a flange 14: arranged at a right angle to the upper flange 9 and disposed on top of a flange 15 of an outlet port 16 which leads from a steam manifold 17 provided with a port 16 for each of the spur tubes.
Whenever it is desired to replace a spur tube it is only necessary to remove the appropriate elbow, draw out the old tube and insert the new one.
It will be observed that very tight joints are provided between each tube and the pan and that the joints are exposed so that a leak could be immediately-located.
Moreover it will be noted that the walls of the pan are substantially neutral so far as all pressure in the tubes is concerned;
the pressure being transmitted from flange to flange lengthwiseot the tube.
The device of this invention isv strong, simple, durable and inexpensive in construction as well as thoroughly reliable and practical in operation and capable of quick and easy repair.
Having described my invention, what I believe to be new, and desire to secure and protect by Letters Patent of the United States is:
1. An evaporator comprising a. pan having removable spur tubes arranged therein end to end and spaced from each other.
2. An evaporator comprising a pan having removable spur tubes arranged therein and slightly spaced, a steam manifold "at each end of said pan provided with flanged outlets, and a flanged elbow connecting each flanged manifold outlet with one of the flanged ports, each elbow having mounted therein a bleed pipe adapted to project into the adjacent spur tube,
In testimony whereof, lVILLIAM E. FLETCHER has signed his name to this specification in the presence of two subscribing witnesses, this 20th day of March, 1916.
WILLIAM E. FLETCHER.
