- This jet-carrying shaft is mounted in a support, which is itself rotated about an axis perpendicular so that of the said shaft.
- the jets are so arranged that it is the reaction of the water which drives the jetcarrying shaft and the rotating support.

It is known that apparatus of the type in question generally comprise a rotating shaft provided with a series of jets supplied with liquid or pressurised water, so as to sweep the whole of the interior wall of the vat to be cleaned. This jet-carrying shaft is mounted in a support, which is itself rotated about an axis perpendicular so that of the said shaft.
In known apparatus, the jets are so arranged that it is the reaction of the water which drives the jetcarrying shaft and the rotating support. It will be understood that, for correct operation, the water must be admitted to the apparatus'at a very high pressure; now, such a pressure is not always available. Furthermore, braking means must-be included in the apparatus to prevent accidental racing of the mobile organs; these means complicate the construction of the apparatus and increase its weight and price.
The improvements which form the object of the present invention are intended to permit construction of a simplified apparatus which, however, descales efficiently.
The apparatus in accordance with the invention is characterised in that the support of the jet-carrying shaft is rotated by a drive organ and drives the said shaft through a gearing-down mechanism with perpendicular axes, driven by a planet pinion which is mounted on this support and engages with a fixed, toothed ring-gear, the numbers of teeth on the planet pinion and on the ring-gear being incommensurable, so that the jet-carrying shaft has a different angular orientation after each revolution of the support.
It will be understood that such an apparatus does not require a very high water-pressure, as the mobile parts are driven not by the water, but by an independent drive organ. Any braking mechanism can obviously be dispensed with, and this simplifies construction and reduces the weight and cost of the assembly. Trials have shown that, due to the angular shift of the jet-carrying shaft after each revolution of the support, the efficiency of the apparatus was comparable to that of known apparatus.
The attached drawings, given by way of example, will lead to a better understanding of the invention:
FIG. I is an elevation of a descaling apparatusin accordance with the invention.
FIG. 2 is an axial section of the lower portion of this apparatus, to a larger scale.
FIGS. 3 and 4 are diagrammatic sections along the lines Ill-III (FIG. 2) and IV-IV (FIG. 3) respectively.
FIG. shows the kinematic sequence of the mobile parts of the apparatus in accordance with FIGS. 1 to 4.
The apparatus shown in FIG. I comprises a base I, so shaped as to bear against the edge of the openings in the vats to be descaled. This base I carries an electric, pneumatic or hydraulic drive motor 2, the said motor being associated with reduction gearing 3. On the side opposite to assembly 2-3, base I is rigidly attached to a vertical column 4, forming a housing for the output shaft of reduction gearing 3; this shaft 5 is in tubular form, its interior space communicating through a swivel joint with a fixed pipe 6, to which is connected a feed channel 7.
As shown in FIG. 2, the lower end of fixed column 4 is provided with an annular flange i8, forming a support for a toothed ring-gear 9, the axis of which coincides with that of the said column 4 and of drive shaft 5. In the same way, the base of shaft 5 is rigidly connected to a cylindrical hub 10, centered inside column 4 by a bearing II. This hub I0 is hollow to form a crooked channel 10a, the upper opening of which communicates with the interior space of shaft 5.
A cylindrical part I3 is fixed'against the lower, suitably shaped face of hub 10, by a series of screws 12, and is thus rotated simultaneously with hub 10 and shaft 5; a packing I4, associated with a stop 15 rigidly attached to the base of toothed ring-gear 9, ensures the tightness of the rotation of the assembly or support 10-13 relative to the said ring-gear 9. Piece 13 has a transversal bore at 13a to form a housing for a sleeve I6, inside which a horizontal, tubular shaft 17 is mounted in cantilever; the interior space 17a of this shaft I7 is connected by borings I71; and an annular port I8, to a channel 13b, formed in part 13 so as to open opposite the lower end of the above-mentioned crooked channel 10a.
The end of shaft 17 which projects laterally beyond piece 13, carries a head 19, which is radially threaded to receive two arms 20, provided with a nozzle or jet 20a with a calibrated insert. Between this head 19 and one of the two bearings 21 which support it in part 13, this shaft 17 is provided with a hollow toothed wheel 22, suitably keyed on the periphery of the said shaft; this wheel 22 engages with a worm 23 (FIGS. 4 and 5) rigidly attached to a stub shaft 24, mounted in bearings 25 introduced into a vertical bore in part 13. The top of stub shaft 24 receives a pinion 26, which cooperates with the teeth of ring-gear 9 in the manner or a planet-wheel.
It should be noted that the numbers of teeth on ringgear 9 and on planet pinion 26 are incommensurable. To crystallize these ideas in a precise example which, however, is in no way of a limiting nature, it may be supposed that ring-gear 9 has 59 teeth, while pinion 26 has IS. The reduction ratio between this pinion 26 and the hollow wheel 22 which co-operates with worm 23 is variable, the said wheel having thirty teeth in the example in question.
The operation and use of the apparatus described above will be easily understood. Column 4 is inserted into the vat to be descaled, base I resting against the edge of the opening in the latter. Motor 2 is started simultaneously as channel 7 is connected to a supply of pressurised liquid or water.
Assembly or support 10-13 is thus rotated continuously relative to ring-gear 9, which is held angularly fixed by column 4. Planet wheel 26 carried by the above-mentioned assembly engages with ring-gear 9, so that stub shaft 24 is rotated, this movement being communicated to jet-carrying shaft 17 by reduction wormgear mechanism 23-22. Jet-carrying arms 20 therefore spin about the axis of this shaft 17, simultaneously as support 10-13 moves angularly about the axis of drive shaft 5. The water which enters this shaft 5 passes through channels 10a and 13b, is admitted to shaft 17 through port I8 and borings 17b and is projected through jets 20a against the interior wall of the vat to be cleaned.
It will be appreciated that the apparatus can operate with absolutely any liquid pressure. Of course, this liquid can be heated to improve descaling, or a detergent or solvent may be added to it. Moreover, and principally, the way in which jet-carrying shaft 17 is driven by pinion 26 and ring-gear 9 ensures continuous sweeping of the vat wall, with the introduction of a jet shift effect at each rotation. Returning to the numerated example given above, it will be understood that, taking into account the two jets of the apparatus, at the end of thirty revolutions of drive-shaft 5, the said jets will have adopted 60 different positions, so that there is in effect an impact point every 6. After this first cycle, support 10-13 commences a second cycle of 30 revolutions, during which the jets will adopt 60 new angular positions, staggered relative to the first ones by 0.8 of angle. In short, for jet-carrying shaft 17 to return to its initial angular position, it must effect seven and one half cycles, or in all 225 revolutions of shaft 5. If it is supposed that this shaft rotates at revolutions per minute, the operations as a whole will last 15 minutes, with a very concentrated sweep (an impact every 0.8 of angle).
It is self-evident that the user can decrease the number of cycles, depending upon the nature of the work to be carried out, e.g., if the vat in question only requires washing. It will be noted that shaft 17 can carry any number of jets; in certain cases a single jet will be sufficient, which is obviously impossible with conventional descaling apparatus, in which drive is provided by the reaction of the projected water. The apparatus can be used in the horizontal position as in the vertical; it can even be positioned with base 1 turned downwards, provided of course that assembly 2-3 lends itself to such a position.
