One example of prior art apparatus of this general character is shown in the U.S. Patent to Booth No. 3,402,725 issued Sept. 24, 1968 and entitled Bulk Tank Washing Apparatus.

Another type of prior art cleaning apparatus of this general character utilizes a rotatable spray head having a series of apertures extending therethrough at an angle so as to diffuse jets of cleaning solution in all directions and also cause rotation of the nozzle. Such a device did not efficiently use the horsepower of the liquid pump, and did not always operate satisfactorily because of the friction and binding created between the relatively moving parts.

An example of this nozzle is shown in my U.S. Pat. No. 3,448,742 issued June 10, 1969 and entitled Portable, Automatic Washing Unit for Tanks." That patent as well as my U.S. Pat. No. 3,583,412, issued June 8, 1971 entitled Automatic Washer Unit for Storage Tank or the Like both show tank apparatus of the type with which the present invention finds particular utility.

SUMMARY OF THE INVENTION The present invention provides a rotatable spray nozzle assembly for cleaning the interior of a tank, and which nozzle assembly includes an outer, rotatable nozzle member and an inner, stationary member which to gether define two separate chambers that are separated by an automatic operating valve. Fluid pressure enters the first chamber and is directed through the apertures in the rotatable nozzle member to cause a series of jets of fluid to be emitted in all directions. After the pressure has sufficiently built up in the first chamber to cause the said establishment of such jets of fluid, the valve between the chambers automatically opens and fluid pressure is admitted to the second chamber where it is then directed outwardly through angularly disposed passages to consequently cause rotation of the nozzle member.

The above nozzle furthermore includes a single point bearing between the outer rotatable nozzle member the fluid valve which is fomied between and by the two members. When the outer member is thus shifted upwardly due to fluid pressure which is built up in the first chamber, a single centrally located bearing is established between the relatively rotating parts thereby providing a low friction bearing These and other objects and advantages of the present invention will appear hereinafter as this disclosure progresses, reference being made to the accompanying drawings.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a view of a bulk tank, certain parts being broken away for clarity and showing the nozzle assembly of the present invention located therein;

FIG. 2 is a perspective exploded view of a spray nozzle assembly embodying the present invention;

FIG. 3 is a vertical, cross-sectional view through the assembly when the valve between the relatively moving members is closed;

FIG. 4 is a view similar to FIG. 3, but showing the valve open when the assembly is in full operation and and the relatively stationary interior member. In addition, a fluid bearing is formed at each of two widely spaced locations between the outer rotatable nozzle member and the relatively stationary inner member, thus providing good lubrication and minimizing binding between the parts. I

The construction and arrangement of the improved nozzle assembly is such that a relatively small fluid pump may be used in a particularly efficient manner in that pressure is established first in one chamber to thereby create the jets of fluid from the nozzle, and then the second chamber is pressurized to rotate the nozzle. The sequence of pressurizing the chambers is automatic in that after the first chamber is pressurized, the outer rotatable nozzle member shifts axially relative to the inner stationary portion, that is to say it shifts in an upward direction, thereby automatically opening the outer member is rotating;

FIG. 5 is a generally horizontal sectional view taken along line 5-5 in FIG. 3; and

FIGS. 6 and 7 are cross-sectional views taken along line 66 and 77, respectively, in FIG. 3.

DESCRIPTION OF A PREFERRED EMBODIMENT As shown in FIG. 1, the nozzle assembly N provided by the present invention is located in a bulk tank T and it may be suspended rather loosely in a downwardly hanging direction by a conduit 2 which is attached to the upper end of the assembly, and which conduit supplies fluid under pressure, such as a cleaning solution, to the nozzle from a pump not shown). It is desirable to be able to use as small a fluid pump as possible for these devices, for the sake of economy. At the same time these pumps must deliver sufficient volumes of water at sufficient pressures in order to do a satisfactory job of cleaning the tank.

More specifically, the nozzle assembly includes a central tubular member 3 having a shoulder 4 formed on its outer periphery and generally adjacent its upper end. The conduit 2 is slipped over the upper end of member 3 and is frictionally held in sealing engagement therewith. Adjacent the lower end of member 3 is a pair of diametrically opposed, rather large openings 5, and the lower end of the member 3 is closed by the diametrically enlarged portion 3a, which includes a radially extending annular shoulder 3b. An outer, generally hollow cylindrical member 6 has a bore 7 which adjacent its upper end forms a relatively loose fit with member 3. That is to say, the fit is such that pressurized fluid is permitted to flow upwardly between the juncture of the member 3 and the bore 7, providing a fluid bearing at one end of the rotatable member 6. The lower end of the member 6 has a radially extending annular shoulder 8 which cooperates with shoulder 3b to form a fluid valve V, as will appear. The diameter of the enlarged bore 9 of member 6 is larger than the diameter of the enlarged portion 3a of the stationary part 3, so that fluid can flow through the annular space 10 therebetween and into the lower end of member 6. The lower end of member 6 is closed by a removable end cap 12 which has an annular sealing rib 13 cooperating with a complementary annular groove 14 in the interior of member 6. The end cap 12 has a plurality of circumferentially spaced apertures 15 extending therethrough and which are arranged at an angle to a radius so that pressurized fluid being ejected therefrom causes rotation of the nozzle member.

A single, centrally located bearing means is provided in the end cap 12 in the form of a threaded cap screw 17 having a lock nut 18 so that the end 19, which forms a single point of bearing surface, can be adjusted axially. As shown in FIG. 4, when the outer portion 6 is raised, as when the device is operating fully, the end 19 bears against the lower central portion of inner member 3 and insures a low friction bearing for the rotating member 6. When it is in this position, the upper end of member 6 is spaced a distance from an upper 4 collar 22. Thus, cleaning solution fluid can flow upwardly through the annular space 7 and is directed downwardly by the overhanging flange 23 of the upper collar, thereby providing the fluid seal previously mentioned.

The collar 22 abuts tightly against shoulder 4 and the collar 22 is press fit on member 3 to form a fluid seal therewith.

With the above construction, a first chamber 30 is formed by and between the rotatable member 6 and the stationary member-3 and when pressure fluid is introduced via the conduit 2, it flows through the openings of member 3 and pressurizes chamber 30, causing fluid to be ejected through the series of apertures 32 which extend through the wall of member 6. The apertures 32 are arranged at different angles so as to create a series of jet sprays of cleaning solution in all directions. After these jet sprays have been thus established and are in operation, the pressure in chamber 30 lifts member 6 upwardly to the position shown in FIG. 4 thereby opening the valve -V formed between-flange surface 3b and flange surface 8. This permits pressurized fluid to flow into a second chamber 33 at the underside of member 3 and this pressure fluid then is forced outwardly through the angled apertures thereby causing rotation of the outer member 6. The

nozzle is then in full operation and may rotate at a relatively slow rate.

Resume The spray nozzle apparatus of the present invention includesa two-chamber, rotatable nozzle wherein the pressure must build up sufficiently in a first chamber to thereby establish a series of pressurized jets, and then the outer rotatable nozzle member raises to open the valve defined by and between the rotatable nozzle member and the stationary member. Then the fluid causes the second chamber to be pressurized resulting in rotation of the nozzle after the jets have been established. The single point bearing is brought into contact with the stationary member and together with the two widely spaced water bearings provides efficient operation of the unit with a minimum size fluid pump. The upper end of the assembly need not be made with close manufacturing tolerances between the rotatable parts, and there is no binding when the nozzle may be tipped from the vertical position as when hanging in a tank.
