Definitions

  • the invention refers to a self-cleaning system for air filter in dry-cleaning machines acting constantly during the machine operation.
  • said machines the air flow which arrives into the suction duct from the rotating basket, where is clothing to dry, crosses a filter unit which keeps the impurities, made of nap and other, while air reaches into the drum condensation hollow and then into the force main for its re-employment.
  • a filter unit which keeps the impurities, made of nap and other, while air reaches into the drum condensation hollow and then into the force main for its re-employment.
  • it is necessary periodically to intervene as a first step taking out said unit from machine beforehand opening of special handole; the same filter unit must be then cleaning with conventional means and then brought back in its position inside the machine. But acting in this way it is putting in connection the machine inside system, where are present toxic agents, with the working environment so determining an air pollution and a big inconvenience for the operator during the withdrawal and resetting phases and also during filter cleaning.
  • the invention avoids the above indicated disadvantages by adopting a new concept system acting with integrated self-cleaning effect which, with machine in operation, acting constantly the filter unit cleaning.
  • the system foresees the use, into the machine suction duct, of a rotating filter 1 driving by a motor reducer 2 which keeps the suspended impurities.
  • a turbine 3 By means of a turbine 3, the nap deposited on filter 1 is sucked by an intake spout 4 which, through the piping 5, puts into a cyclone 6 in which is actuated the separation between air and nap and, while said nap is keeping, the air through piping 7 is putting again in circulation for its reuse.
  • Said self-cleaning effect is constantly actuated during the machine operating.
  • the self-cleaning filter may precede, into the suction loop, a second conventional filter so that, being not said second filter subjected to dirty oneself during the right machine operation, it can perform to a reserve filter action for safety condition.
  • a filter moved by a motor reducer 11 with shaft 12 passing into the coaxial support 13 fixed to cover 14 for frame 15 rotation, with wire cloth 16.
  • Said filter permits moreover a frontal seal by means of crawling gaskets 17 and 18.
  • a thrust coil spring 21 which operates as retaining so to maintain the rotating part 15 against the machine hose 22.
  • sheet 1 fig. 1 is schematic view of the machine.
  • sheet 2 fig. 2 is section view of the rotating filter.
