BOILER-C LEAN ER.
SPECIFICATION forming part of Letters Patent No.543,541, dated uly 30, 1895.
Application filed March 18, 1895- Serial No. 542,256- -(No model.)
zen of the United States, residing at Blue Island, in the county of Cook and State of Illinois, have invented a new and useful Improvement in Boiler-Cleaners, of which the following is a specification.
This invention relates to boiler-cleaners;
and its object is to simplify and improve the.
to construction of the same and to render the same more eflicient and certain in operation.
The invention consists substantially in the construction, combination, location, and relative arrangement of parts, all as will be more I 5 fully hereinafter set forth, as shown in the accompanying drawings, and finally more specifically pointed out in the appended claims.
Referring to .the accompanying sheet of drawings and to the various views and refer- 2o ence-signs appearing thereon, Figure l is a view in side elevation of a portion of a steamboiler with my invention applied thereto, part of the boiler-setting being broken away to show the relative arrangement of the parts 2 5 comprising my invention. Fig. 2 is a central longitudinal sectional View of the precipitating or settling chamber. Fig. 3 is a detail view in plan of the skimmer. Fig. 4 is a detail view in central section of a swivel-union 0 joint for the skimmer-frame.
The same reference sign is employed throughout the several views to designate the same part wherever it occurs.
Reference-sign A designates a steam-boiler 5 of any desired or well-known construction mounted in any suitable setting 13. As is well known by persons skilled in the art, the act of ebulition in a new boiler creates a seething or surging of the water contained therein.
This action of the water causes all the impurities contained in the water, such as mud, sludge, lime, or other impurities, to rise to the surface. If this foreign matter is not removed it settles to the bottom when the boiler cools 4 5 down, and becoming deposited upon the tubes or shell of the boiler forms a scale. Repeated depositions of impurities from water increases the amount ofthe scale, and without relief the boiler is soon rendered inefficient in its heating capacity and actually dangerous on account of its liability to explosion, due to overheating the scaled tubes or shell. It is a known fact that nearly all the impurities in the wa ten are contained in the upper five or six inches of the water during the process of steam-generation, and to the removal of these impurities and foreign matter while carried at or near the surface of the water in the boiler is my invention directed. In order to accomplish this result I arrange in the boiler what I shall call genericallya skimmer. In Fig. 3 I have shown a desirable form of skimmer, which comprises a T-connection 5, having suitable pipes 6 7 communicating with the respective ends thereof, which pipes project parallel with each other and are joined at their outer ends by means of cross-pipe 8. In communication with the series of pipes 6 7 8 and projecting therefrom are a series of wide-mouthed funnels 9. These funnels may be arranged to point in any suitable or desirable direction and may be of any desirable number to perform the work required of them. The connection of pipe-sections 6 7 with the T-connection 5 is preferably a swivel or pivoted connection, in order to permit the frame of the skimmer to rock or swing up and down thereon, for a purpose that will more fully presently appear. construction embodying this idea, wherein is shown a substantial ball-and-socket union or joint.
It will be seen that it is important to provide for varying levels of the water in the boiler, in order to secure the greatest degree of efficiency and the widest range of use of the attachment, and hence the importance of pivotally mounting the skimmer-frame. In order that the funnels may always occupy an effective position with reference to the surface of the water, whatever the variations in height of the water-level may be, within reasonable limits, I mount upon the skim mer-,
I have shown in Fig. 4 a
frame a float 10, which serves to maintain the pivoted skimmer-frame, and hence, also, the funnels always in proper position on the surface of the water.
From the T-connection 5 a suitably arranged pipe 11 leads out through the boiler and into a precipitating or settling chamber 12, arranged in any suitable or convenient location with reference to the boiler. Pipe 11 sections 14 are employed, but it will be understood that any suitable number of such sections may be employed, and I do not desire to belimited to any specific number or an rangement. \Vithin chamber 12 is arranged a series of shields in the form of funnels through which pipe 11 is arranged to pass.
In the drawings I have shown two such shields 1 or funnels reversely arranged with respect to each other-that is to say, the flared mouths of the funnels are arranged to open in opposite directions. In this arrangement the fun nel 15 is suitably bolted and otherwise suitably secured to the inner wall of the chamber 12, with the mouth thereof presented toward the bottom of said chamber. The funnel 16 is arranged with the mouth thereof presented toward and arranged adjacent to the top of the chamber 12, and having the smaller end thereof projected inside the smaller end of funnel 15, a space of suitable dimension being left between the two funnels to permit the passage of steam and water, as will hereinafter more fully appear. The funnel 16 may be supported in any desirable or suitable way. A pipe 17, of larger internal diameter than the external diameter of pipe 11, is suitably supported in the chamber 12, and is arranged to inclose the said pipe 11, as shown, said pipe 17 being closed at the lower end thereof except through a series of suitable openings 18 within the funnel 16, it being preferable to form a tight joint between the lower end of said funnel 16 and the pipe 17, as shown. The pipe 17 leads out through the top of the chamber 12 and connects through a pipe-connection 19 with any suitable return-conduit by which the water passing off therethrough may be returned to the boiler.
The operation of the apparatus so far described is as follows: The steam-pressure in the boiler forces the mud, sludge, or other foreign matter carried upon or near the surface of the water in the boiler into the funnels 9, thence through the pipes 6 or 7 and 11 into the chamber 12, and delivers the same, together with what water and steam as also may'pass over into the settling-chamber 12 through the upturned ends of pipe-sections 14:. The temperature of the chamber 12 being less than that of the boiler, not only is the circulation assisted, but the cooling off of the matter carried into the chamber from the boiler causes the mud and other impurities, having a greater specific gravity to be precipitated to the bottom of the chamber 12, whence it may be removed or drawn off through the blow-0E pipe 20. By reason of the upturning of the delivery-pipe sections 14 it will be seen that the draft created in the settling-chamber is deflected upward,and hence does not agitate the sediment that has already been deposited in the bottom of chamber 12, thereby effecting a thorough precipitation. Moreover, by reason of the fact that the delivery ends of pipe-sections 1a are arranged adjacent to the sides or walls of the chamber, the current therefrom takes the direction indicated by the arrows-that is, rises in the chamber in a stream flowing adjacent to the walls of the chamber, thereby leaving a large space, and hence a large body of water centrally of the chamber practically without material agitation, thereby permittin the process of settling or precipitation to go on rapidly and without interruption, and hence materially adding to the etiicieney of the apparatus. The steam and water passes upward between the funnels 15 16, and into the upper funnel 16, and thence through theapertures 18 into pipe 17, and off through pipe-connection 19, and retu rncd to the boiler in its purified condition for reuse.
In connection with my improved apparatus I provide an alarm to indicate the falling of the water-level in the boiler below the safety or any desired wpoint. In carrying out this idea I arrange an alarm device in connection 11, adapted to be actuated by excess of heat in said pipe. Therefore, when the level of the water falls below any desired point--for instance, when the float 10 is brought to rest upon the top of the upper tubes and no more water can pass into the funnels 9-the steam enters the connection, and being heated to a greater degree than the water which before passed through the pipe effects an actuation of the alarm device. Many different forms of apparatus embodying this idea may be used, and I do notdesire to be limited or restricted to the specific form shown, which comprises a steam-whistle 21', which may be normally closed by means of a fusible plug in any well-known manner, the fusing of the plug by excess of heat in pipe 11 causing the whistle to sound by the passage of the steam therethrough.
In practical operation the boiler-cleaning attachment hereinabove described may be conveniently applied to any existing boiler, and it performs the function not only of removing the impurities contained in the water, bu t, by preventing further deposit of scale upon the tubes and shell of a boiler, it causes the scale which has previously been deposited thereon to break and to become loose by repeated expansions and contractions, thereby permitting the easy removal thereof from the boiler.
It is evident that many variations and changes in the construction and relative location and arrangement of parts would readily suggest themselves to persons skilled in the art and still fall within the spirit and scope of my invention. I desire it to be distinctly understood, therefore, that I do not limit or restrict myself to the exact details shown and described; but having stated the object and nature of my invention, and having described a form of apparatus embodying the same, and having explained the function and mode of operation thereof,
. What I claim as new, and desire to secure by Letters Patent of the United States, isl.
