VULCANIZER CIRCULATING SYSTEM Filed Aug. 1, 1929 I N VEN TOR.
A TTORNEYJ Patented am. 27, 1933 unirso stares PATENT OFFICE V 04w. BROWN, or AKRON, onto, ASSIGNOR TO THE rrnns'ronn TIRE & RUBBER coM- PANY, or AKnoN, 01110, ajooitronarron or OHIO VULCANIZER CIRCULATING SYSTEM Application filed August 1, 1929. 7 Serial No. 382,616.
This invention relates to vulcanizers and particularly to steam circulating systems therefor.
The general purpose of the invention is to 6 provide a steam circulating system either singly or in batteries to the vulcanizer or vulcanizers atjany predetermined temperature.
The foregoing and other objects of the 10 invention are attained in the steam circulating system for vulcanizers shown in the accompanying drawing and described below. It is to be understood that the invention is not limited to the particular form thereof 16 shown and described.
The drawing shows a portion of a vulc-anizer system in which the invention is embodied.
Referring to the drawing, the numeral 10 designates a vulcanizer of the steam jacketed type to which steam connections are made at 11, 12 and 13. A steam supply line 14 is connected through a steam injector 15 to the vulcanizer, a pipe '16 being provided for this purpose. In order to more accurately control the steam passing to the vulcanizer, a check valve 17 may be placed in the line 16.
, At the bottom of the vulcanizer is provided a header 18, connected to the line 19 which 1 0 in turn is connected to a T 20. The numeral 21 designates an exhaust line arranged to be connected through a valve 22 to one side of the T, the other side of the T is connected to a line 24 running to the injector 15. To as- ..3 sist in controlling the exhaust steam, an ordinary check valve 23 is preferably placed in the exhaust line as shown. Adapted to control the valve in the nozzle 15 of the injector 15 is a hand wheel 25.
The exhaust valve 22 is adapted to be controlled by some automatic means such as a temperature controller 26 which may be mounted on a control panel 28 upon which are placed various other instruments which indi- 4 cate pressures and temperatures of certain parts of the system. A mercurial thermometer 27 may also be placed as shown in the line 24. v The operation of the circulating system is as follows: The incoming steam from the supply line 14 is fed to the nozzle 15 of the injector 15, thence through the line 16, through the jacketed walls of the vulcanizer and out the header 18 and the pipe 19 to the T 20. The temperature of the steam in the circulating system operates thermostat 20', which, working through the temperature controller 26'actuates the valve 22 which permits all of the condensate and a portion of the live steam to automatically. escape to the exhaust line 21, whereby a uniform temperature is kept in the vulcanizer. This controlling system eliminates the use of a steam trap which .cheapens and simplifies the system while providing circulation. I Any steam dumped into the exhaust line aids of course in the circulation of the remaining steam through the vulcanizer. i
All steam which has not been permitted to escape to the exhaust line is then drawn up into the return'line 24 by the action of the injector 15 and is mixed with the incoming steam. In the form of the invention shown, this action of the injector, controlled through hand wheel 25, is such that one foot of live steam from the supply line 14 entrains approximately 2 cubic feet of steam from the return line 24, thus circulating the same steam through the system, whereby more of the power of the steam isused and at the same time keeping a'more uniform temperature in the vulcanizer.
Inthe embodiment shown, approximately 200# of steam per hour is used. The pressure in the supply line 14 is preferably about 85 150# per square inch, which drops to near 65:#: per square inch after passing through the injector.
The vulcanizers may be in batteries wherein one control panel and injector is used for several vulcanizers or each vulcanizer may have its own control panel and injector, and the individual systems connected merely to common steam and exhaust lines.
It will be apparent that the invention is 95 capable of application in other than the specific form shown, accordingly, various modifications of the invention can be resorted to without departing from the spirit of the invention or the scope of the appended claims. 1
What is claimed is:
1. In combination, a jacketed member, a steam injector and a steam supply line, said supply line being attached to the nozzle of the injector, pipes, one of said pipes connecting the, charging end 'of the injectorito the jacketed member and another of said pipes leading from the jacketed memberto the feeding line of the injector, an exhaust valve in the last named pipe, and a temperature controller, said temperature controller being controlled by the tempcratureof the steam in the jacketed member and controlling in turn the movement of the valve.
2. In combination with a vulcanizer having a steam jacket, a steam supply line and anexhaust line connected to said jacket, an exhaust valve in said exhaust line, a temperature controller including a thermostat for opening the exhaust valve to draw off condensate formaintaining a uniform steam temperature 1n said acket, and a steam III-:7,
, perature of the steam in the circulating system, and means actuated thereby to open said 7 exhaust valve for draining 0H condensate for maintaining a uniform steam temperature in said circulating system, and means comprising a steam injector for circulating steam through said jacket and said circulating system as the condensate is exhausted therefrom to eliminate the formation of dead spaces ROY W. BROWN.
