Definitions

  • the present invention concerns a vibrating machine for the drying of metal pieces by means of hot air and absorbing material.
  • the finishing processes are effected by using water solutions and/or suspensions of various chemical compounds with detergent, pickling, abrasive or colouring action and they must, therefore, always be completed with a washing cycle of the finished pieces.
  • the washing cycle which normally employs water, must always be followed by a drying cycle of the washed pieces before these are packed for despatch or submitted to subsequent terminal processes such as painting or punching.
  • the water in fact, tends to adhere to the surface of the metal pieces in the form of small drops which may leave calcareous residue (if normal water is used for the final wash) or stains, but in any case the drops favour surface oxidation of the pieces if these are made from metals or from alloys subject to oxidation.
  • the system which uses solid absorbing material, broken down into small particles, such as wood sawdust or other synthetic and natural materials. These materials have the power to absorb a great quantity of water in proportion to their own weight and, furthermore, they exercise a very slight abrasive action on the surface of the pieces processed, without interfering with the finishing specifications and, indeed, they perfect the polish.
  • the water soaked drying material is then heated to remove the water absorbed, after which it can be recycled.
  • the pieces to be dried are put into the vibrating machine and yield the humidity to the drying material.
  • the dry pieces are separated from the drying material and discharged from the machine by screening.
  • the heating system can be either by contact with a hot plate or by elements in contact with the drying material or, by the more modern system of the input of hot air into the vibrating ring as, for example, described in a preceding patent application by the same inventor.
  • the vibrating bowl is obtained out of a metal construction, for the simpler models with a one turn scroll, but the construction can be obtained also in polymeric material, generally of the elastomer type, using a mould which produces the ring shaped bowl.
  • the metal construction can have an ascending scroll which makes more one turn, but the turns are limited by the weight of the scroll which dictates the use of very powerful vibrators and with great amplitude of vibrations. The great amplitude of the vibrations can cause damage to the pieces being dried.
  • a plastic lining is required for the metal scroll to prevent the pieces from becoming damaged, such a lining is very difficult to carry out if the scroll has more than one helix.
  • the metal driers are noisy and require a soundproofing cover to prevent excessive disturbance in the places where they are installed.
  • the machine described in the present invention resolves all the problems of traditional vibratory driers and, furthermore, has a definitely low cost.
  • the machine for drying metal pieces by means of hot air and absorbing material comprising a vibrating section being put into vibration by means of a motor and a non vibrating section essentially consisting of an air heating equipment and being connected with the vibrating section, is characterised by the fact that :
  • the tubular ascending scroll consists of a pipe with a diameter from 15 to 25 cm being the same as the cavity wall between the two concentric metal cylinders.
  • the pipe is wrapped round the inner cylinder to form a scroll with a sufficient number of helixes to ensure a length of run adequate for the perfect drying of the pieces being processed.
  • the number of helixes is between two and five.
  • the pipe is made of polymeric material of polyolephinic, silicone, polyester or polyamide type. It is also possible to use the abovementioned materials reinforced with natural, synthetic, artificial, glass or metal fibres.
  • the residual space in the cavity wall is filled by a casting of a liquid elastomer resin which is subsequently hardened by polymerization.
  • This type of construction therefore, allows the obtainment of machines with an elastomer material scroll, without recourse to a particular type of mould; it also offers the possibility of obtaining more than one helix and a closed processing chamber and not a wide open one as in the normal machines moulded in polymeric material.
  • the lower part of the tubular ascending scroll is connected to a semi-circular trough gutter for the charging of the pieces to be dried and of the absorbing material.
  • a grid is inserted in the lower part of the trough to allow the elimination of the undersized particles of the absorbing material which, owing to the grinding effect of the pieces during the drying process, have been reduced to dimensions not in conformity with the desired granulometry.
  • Another semi-circular trough gutter, with a gridded bottom is connected to the lower part of the tubular ascending scroll and allows the separation of the drying material from the pieces, which are then directed to the packing stations or to other processes, the material is then recycled into the lower (charging) trough for further use.
  • Both the lower and the upper troughs are a fundamental part of the vibrating section of the machine.
  • the vibrating section of the machine consists of two concentric cylinders: 1 and 2, constructed in metal plate, resistant to vibration fatigue; a flexible pipe in plastic material (3) is wound round on the inside of the cavity wall between the cylinders to form an ascending scroll with three and a half helixes.
  • a pouring of elastomer material (4) of polyurethane type is made, the material is highly wear resistant and, when polymerized, it hardens and imprisons the flexible pipe (3), which, in this way, becomes a disposable mould for the polymerized polyurethane. In this way, a completely enclosed ascending scroll is formed, which becomes the drying chamber.
  • the vibrating section of the machine is fixed to a supporting base (17) by means of springs (16) and is put into vibration by the motor (15).
  • a heating unit is fixed to a non vibrating support base outside the drier, the heating unit consists of armoured electrical elements (7) and of a suction fan (8), these are connected by flexible hose (9) respectively to points (5) and (6): entry and exit of the scroll.
  • the air is sucked up by the fan (8), which is connected to the terminal part of the scroll and enters the heating unit (7) whose temperature is controlled by a thermostat (14), mounted in correspondence with the air suction.
  • the temperature of the air exiting from the scroll depends on the quantity of water evaporated, that is on the degree of humidity of the absorbing material.
  • the thermostat (14) allows the control of the amount of power to be supplied to the heating system (7) according to the degree of humidity desired in the absorbing material so optimizing to the maximum the power consumption.
  • the air heated in the heating unit (7) enters the lower part (5) and exits from the upper part of the tubular ascending scroll (6).
  • the fine absorbing material dust which forms during the drying stage, is transported in suspension (airborne) by the air which passes through the scroll and is caught in the air filters (not shown in the drawing) which are placed before the suction fan (8). In this way, both the air circulation in the machine and the dust removal from the drying material, as well as the elimination of fine particles, are ensured with only one suction fan (8).
  • the elimination of the particles of absorbent mterial of unsuitable granulometry, but not small enough to be airborne inside the scroll, is carried out in the outside run machined on the lower part of the drier, which consists of a trough (12), with a gauged gridded bottom (13), attached to the vibrating part of the machine, which serves to separated the undersized particles of the recycled drying material issuing from the ridding grid (pieces/material) situated in the upper part of the machine (not shown in the drawing).
  • Trough (12) is also the charging point for the pieces to be dried.
