SNOW, OF
DETROIT, MICHIGAN, ASSIGNORS TO DIA- MIGND POXVEB SPECIALTY CORPORATION, OF DETRDXT, MICHIGAN, A CORPORATION OF MICHIGAN BOILER CLEANER This invention relates to boiler cleaners and relates particularly to boiler cleaners employing the dischar e of steam or some other fluid to dislodge soot deposits from the boiler tubes and other parts.
One of the objects of the invention is to provide a blower unit movable about its axis and having its fluid supply controlled by a disk valve adapted to maintain said supply during a predetermined portion of the blower movement and cutting off said supply during the balance of said movement.
A feature of the invention is a provision for automatically unseating said valve prelimisame so as to materially reduce the frictional resistance to such rotation.
In the drawings Figure 1 is a sectional view showing a blower pipe equipped with the improved valve control and adjustment means;
Figure 2 is a cross sectional View of the valve, the section being taken on line 22 of Figure 1;
Figure 3 is a detail cross section on line 3-3 of Figure 1 showing a feature of the valve control;
Figure 4 is a view similar to Figure 1 showing an alternative construction;
Figure 5 is a cross section on Figure l.
In these views the reference character A designates a boiler wall and B a number of the boiler tubes. C is a rotative blower pipe mounted transversely of said tubes and passing through an opening C in said wall, said pipe being provided with suitable discharge nozzles C. Exteriorly of the wall A a chambered head D is mounted fast upon the pipe C, said head having its outer end closed and being formed with an inlet port D for steam or some other cleaning fluid. For rotating the blower pipe a shaft E is connected to the head D, said shaft having a squared extremity E longitudinally movable in a correspon ding socket in the closed end of said head. F designates a chain wheel for actuating the blower pipe, said wheel being screw threaded upon a reduced stud F formed upon the outer end of the shaft E. G and G desigline 5-5 of bers J and J, the latter being in constant 1923. Serial No. 623,031.
nate a pair of complementary members i forming a valve chamber into which the head D projects through a packed journal bearing G in the member G, said parts G and G be ing clamped in coacting relation by bolts H. Between the members G and G there is clamped a plate I having a steam port I in the form of a sector of said late. The plate I divides the valve casing G into chamcommunication with the blower pipe 0 through the port D and the former having a fluid supply pipe K opening thereinto. Within the chamber J a disk shaped valve member L is mounted fast upon the shaft E in close proximity to the plate I, said member preferably being welded upon said shaft. The valve member L has a sector portion removed therefrom, the radial marginal edges of said portion being indicated at M. When the blower pipe C is rotatively actuated by means of the chain wheel F and shaft E, the valve member L rotating with the shaft E closes communication between the chambers J and J except of registration with the port I of the opening formed in said valve member between the edges M thereof. Thus the size of the angle between the edges M accurately predetermines the arc of rotation of the blower pipe during which steam is discharged from the nozzles of said pipe. A portion of the surface of the disk I marginal to the port I is slightly raised, as indicated at N, to form a seat for the valve member L. Owing to the v considerable extent of said seat and to the considerable area of the valve member under a fluid pressure urging said member to said seat, a large frictional resistance would oppose turnlng of the valve member unless disengaged from its seat preliminary to rotation. The screw threaded mounting of the chain wheel F upon the outer end of the shaft E is for the purpose of efiecting the desired preliminary unseating of the valve member. Thus when the chain wheel is actuated to the right, said wheel initially turns upon the stud F, thus feeding inwardly relative to the shaft and exerting pressureupon a thrust bearing 0 to shift the shaft E outwardly during the interval and the valve member L clear of its seat. 0 is a yoke member rigidly projecting from the casing element G and forming a seat for the thrust bearing 0. When the blowing operation is completed it is necessary to shift the shaft E inwardly to again permit the valve member to properly seat. This inward actuation of said shaft is permitted by a slight reverse (or COIUItGP ClOCkWlSG) actuation of theehain wheel F whereby said chain wheel is turned upon the stud F and thus fed 0utwardly relative to the shaft to its normal position indicated in dash line and the shaft is urged inwardly by the fluid pressure. To prevent participation of the shaft E in the reverse travel of the chain wheel an ordinary ratchet disk P is mounted fast upon said shaft between the yoke O and casing G, G and a pawl P, mounted upon said yoke, is engageable with the teeth of said ratchet wheel. Thus when the-chain wheel is reversel-y actuated, the shaft is locked while the chain wheel is shifted upon said shaft to per- In-it the valve member to seat.
In the alternative form of the invention disclosed in Figures 4 and 5 the blower pipe C ported valve seat I disk valve L and stem E the chain wheel F all correspond to the first described form of the invention. In this modification, however, a radially pro ject'ing lug L- is formed marginally upon the valve member 'L and is adapted to limit rotation of the valve member by engagement in the respective limiting positions with pins L and L projecting from the member 1 Thus in either of said limiting positions (as respectively indicated in dash lines and dotted lines in Figure 5) the valve member L closes the port I, said port being opened during a portion of an angular'movement predetermined by the location of the pins L and L. Inthis construction the chain wheel "is secured fast upon the stem E by a pin F.
It is a common feature of the several described alternative adjustment devices that the blower pipe with its fluid supply head is fixed with relation'to the boiler tubes to be cleaned rather than through attachment of said head to the boiler wall as in the prior practice.
The termsrotatable .or rotative, as employed in the specification and claims of this application signify revoluble through either a partial revolution or a plurality of revolu tions while the term boiler wherever used in the specification or claims is to be construed as meaning a heat-transfer apparatus vor fluid heater of any character, andthe term boiler cleaner .is ;to be construed as meaninga cleaner for any such apparatus.
