Definitions

  • the present invention relates to a vibrating machine for the finishing, the washing and the drying of metal pieces consi­sting of a round bowl the upper part of which is closed by a cover; a portion of said cover being mobile around a pin fit­ted to the center of the bowl; the bottom of said round bowl being provided with three or more round openings protected by a grid, located symmetrically in respect with each other and connected to the center part of the bowl by means of tubular pipes; said central part having the function of settling tank through which the air used for the drying of the pieces con­tained into the bowl is suctioned at the end of the finishing and washing processes.
  • the finishing processes are ef­fected with the help of the regular movement of the mass being processed which consists of the granulated solid media (of various shapes and sizes) used for the finishing proces­ses, the aqueous solutions/suspensions of suitable chemical compounds and the pieces to be treated.
  • aqueous solutions and/or suspensions of chemical compounds perform the detergent, pickling, abrasive or co­louring actions and they must, therefore, always be completely eliminated not only by a settling process but by washing the finished pieces.
  • the mass under process lacks one or more of the above mentioned components as, for instance, when the abrasive or polishing effect is obtained by making the pieces rub one against the other or when the aqueous solution is not used.
  • washing cycle In any case, at the end of the finishing processes, not only the compounds used for finishing operations but also the particles which have been detached from the pieces under pro­cess, must be eliminated and a washing cycle is always neces­sary.
  • the washing cycle normally carried out with water, must always be followed by a drying cycle of the washed pie­ces, before these are packed for shipping or submitted to subsequent terminal processes, such as painting or punching.
  • Water in fact, tends to adhere to the surface in the form of small drops which may leave calcareous residue (if non-de­ ionized water is used for the final washing) or stains, but in any case, the drops favour the surface oxidation of the pieces if these are made from metals or from alloys subject to oxidation.
  • the washing liquid does not consist of water but of a compound which cannot be dispersed in the atmosphere, the drying air must necessarily be conveyed towards waste and recovery systems of the evaporated liquid.
  • the Applicant has been working in the field of metal surface finishing for many years, by using vibrating machines and has described machines for finishing and/or drying processes in several Patents or Patent Applications.
  • finishing and washing processes are normally performed in a certain machine while the drying process is performed in another machine, still of vibrating type, but having shape and devices different from those of the former.
  • the present invention relates to a machine which is particu­larly interesting because it can perform both the finishing/­washing process and the drying process, in subsequent stages, without the need for the pieces under process, to be separa­ted from the processing media and to be conveyed to another machine.
  • the present invention relates to a vibrating machine for the finishing, washing and drying of metal pieces consisting of a round bowl the upper part of which is closed by a cover; a portion of said cover being mobile around a pin fitted to the center of the bowl; the bottom of said round bowl being pro­vided with three or more round openings protected by a grid, located symmetrically in respect with each other and con­nected to the center part of the bowl by means of tubular pipes; said central part having the function of settling tank and through which the air used for the drying of the pieces contained into the bowl is suctioned at the end of the fini­shing and washing processes.
  • the machine consists of a base 1 supporting a round bowl 2 which contains the granulated solid media used for the pro­cess, the solutions or suspensions of the chemical compounds used to obtain the type of finish required and the pieces to be treated.
  • the central part of the machine is divided into two superim­posed sections 3 and 8.
  • Lower section 3 holds the motor (not shown in the figure), which transmits the vibratory movement to the machine, while the upper section 8 acts as settling tank of the liquid used for the finishing and washing proces­ses in round bowl 2. Said liquid is finally drained from the machine through duct 9.
  • Settling tank 8 is connected to round bowl 2 by means of three pipes 10, which end in three gridded openings 11 placed on the bottom of the bowl symmetrically in respect with each other.
  • Round bowl 2 is closed by a cover 4 a section 6 of which ro­tates around a pin 5 fitted to the center of the cover.
  • the displacement of mobile section 6 of the cover around the cen­tral pin 5 allows closing or opening a section 7 of the round bowl 2, which allows pieces to be loaded for the process and unloaded at the end of the drying cycle.
  • the opening or closing of mobile section 6 of cover 4 is advantageously obtained by reversing the direction of rota­tion of the motor which sets the machine in motion.
  • the processing liquid used for said cycle is drained from the machine through settling tank 8 and duct 9. Having achieved the washing of the finished pieces and having drained the washing liquid, the drying process can start.
  • the air coming from heating unit 16 is conveyed by duct 15 towards an opening 14 in the fixed part of cover 4, through which it is fed into the machine.
  • An air suction fan 12 is connected to the central part 8 of the machine by means of duct 13.
  • the suctioning action of the fan compels air to flow downward through the pieces and the processing media contained in bowl 2; this favours the action of the force of gravity for the draining of the residual washing liquid from the surface of the finished pieces, while reducing the quantity of liquid to evaporate with subsequent energy saving.
  • thermo-couple (not shown in the figure), fitted into suction duct 15, whereas the temperature of the outgoing air is controlled by a thermo-couple (not shown in the figure), fitted into suction duct 13.
  • Said temperature is depending upon the presence of water within the mass under process and it remains constant as long as there is still water to be evaporated, owing to the great heat absorption caused by the water evaporation.
  • thermo-couple pointing out the end of the drying cycle is, therefore, particularly important to save energy (it is no use going on drying pieces which are already dry) and taking into account the fact that some types of me­tal alloys are particularly sensitive to heat and could chan­ge their colour with a serious deterioration of the finish degree of the machined pieces.
