or BERLIN, GERMANY. I
SEPARATING APPARATUS.
Application filed February 24, 1927, Serial No. 170,723, and in Germany April 9, 1926.
This invention relates to improvements in known apparatus in which, in the treatment of small iron goods and the like by means ofa jet of compressed gases directed against them, spraying bodies being mixed with the gases, the procedure is such that a rather largenumber of the pieces of work are placed proiniscuously inside a container, the position of which is continually changed, while the pieces of work, sometimes falling freely, are forced through the zone traversed by the treatment jet, and are thus worked up in the desired manner.
In carrying out this method of treatment use has hitherto preferably been made of a drum which is rotatable about a'horizontal axis and upon the ends of which, in front of a central aperture provided in the wall of the drum, is arranged the nozzle that discharges the treatment jet into the interior of the drum, the said nozzle being arranged either immovably or else in such a way that it executes oscillating movements in the planeof the axis of the drum.
Experience has shown that this method of working the apparatus is accompanied by numerous disadvantages. In particular the treatment jet is always effective in an inclined line of impact deviating greatly from the perpendicular and more or less flatly oblique, to the axis of the drum. The disadvantages therebyarising may be obviated if according to the invention the pieces of work are deposited and moved in such a way that during the rotation of the drum, which is supported obliquely in space, they can roll only around themselves upon one of the prismatic sides of the jacket and the partial surface adjacent thereto of the pyramid-shaped bottom, in which case no free fall occurs, but the mass of material slides in the manner of a rolling track in a rather flat layer which is to some extent uniformly spread out upon the support.
, Owing to this change in the supporting and the moving, the following result is obtained:'-The path from the nozzle to the material to be treated is considerably shortened. Owing to this the spraying bodies arrive upon the pieces of Work with considerably greater velocity than in the case of longer obliquely directed flights. Their force is thus not weakened as it is in the case of long oblique paths. If therefore the spraying bodies, as is the casein the formation of coatings, are to remain adhering to the pieces of work, the. power of adhesion becomes greater. Furthermore, if the spraying bodies consistingof molten metal are melted by a flame formed at the mouth of the spraying nozzle, the pieces of work are highly heated by the mouth of the nozzle being brought near to them, as in the case of the apparatus according to the aforementioned patent. By this means the mass of metallic particles striking insuch a thinly'liquid state is greatly. flattened out and distributed, and as the technologist is aware, the grain becomes more- (compressed air for atomization, combustihle gas, oxygen and the like), and secondly in decreased labour and in increased number of the charging of the machine.
In Figs. 1 to 3 of the accompanying drawings is illustrated one constructional exam-- ple of the invention.
Fig. '1 shows a side elevation,
Fig. 2 a front elevation, and r Fig. 3 a sectional elevation through the drum without the frame.
In a frame 1 is horizontally journalled a shaft 2, upon which is mounted a bevel wheel 3, which meshes with a bevel wheel 6. The bevel wheel 6 is secured to a stub axle 5, which is supported in the obliquely abjustable footstep bearing 4. This bearing is car ried by a worm-wheel sector 7, which by the actuation of a worm 8 equipped with a handcrank 9, can be adjusted into various inclined positions, the carrying arms 10 of the footstep bearing 4 transmitting the inclined positions to the drum 11 secured to the carrying arms 10. The drum 11 contains in its interior a charge drum 12 with a prismatic periphery. The drum 12 is secured by its pyramidal bottom 13 to the stub axle 5 of the footstep bearing 4. The charge drum 12, 13 is perforated on all sides, but has no cover A removable cover 14 is however provided upon the outer drum 11 surrounding the tus that discharges the treatment jet, a metalspraying pistol for example, in such a way that the jet leaving the nozzle strikes per-' pendicularly upon the surface of the mass of.
'material that faces it.
If the shaft 2, by actuation of a driving belt plac'ed round the fastpulley 19, is rotated, in the direction of the arrow shown, about the stub axle 5, the mass of material in the charge drum, under the influence of this ro- I tation and of the prismatic periphery or pyramidal bottom, will continually arrange itself in such a way that the individual bodies roll over one another,- bnt the mass as a whole slidesslowly downwards like a rolling track, continues moving, and then rolls upwards again. Allthis occurs in a uniform, thin layer."
- Now it is possible, by adjusting the obliquity of the drum 12, '13, to allow this rolling Work to proceed in such a way as to take into consideration the distinctive character of thc shaping of the individual parts and also of course the speed with which the change of position is to proceed. This different adj ustment of the drum12, 13, and its contents must of course also be accompanied by a corresponding adjustment of the direction of the cantilever arm 16 and of the jet-discharging apparatus 18 secured thereto.
The removal of the dust from the interior of the drum 12, 13 may be effected by connecting the drum 11, to an exhauster, a movable suction pipe 21 permitting of the movements of the drum.
A The charging of the inner drum 12 is efiected, as already mentioned, by opening the I movable parts of the cover 14. The emptying of the completely metallized contents out of the charge drum. 12 is effected by the aid of a slidable part of the peripheral wall of the drum 11. This part, constructed for example as a sliding door 11, is provided with handles 11,- by the raising of which the door can he slid into the position shown in dotted lines in 1 Fig. 3. Uponthis displacement of the sliding door 1'1 the inner drum 12 is laid open. By releasing the closure 24 a-valve-like part 22 of the pyramidical bottom 13 is opened, or else a correspondin ly shaped part of the cyfindricalsurface o the drum 12. The contents of 12 then drop-out of the drums, which are'thus open, into a transporting vessel sea held ready for them. The funnel attachment 2901? the sliding door 11 serves for the discharging of any spraying bodies, which may have passed during the working of the ma chine outof the drum 12 into the drum. 11.
