Definitions

  • the invention relates to a method according to claim 1, for the production of cores for foundry purposes wherein molding material or sand and at least one binder which is at least predominantly inorganic, water-soluble and / or hygroscopic, are mixed by means of a mixing device and wherein this mixture by means of a feeder at least one sand storage unit is fed to a core production device.
  • the invention further relates to a device according to claim 6, for the production of cores for foundry purposes with a mixing device for mixing molding material or sand and a binder which is at least predominantly inorganic, water-soluble and / or hygroscopic, and with a feed device for conveying the mixture to a sand storage unit of a core manufacturing apparatus.
  • the WO 03/22 487 A1 in that the supplied moisture should be effective as a condensate, which in turn can lead to excessive dilution of the mixture of sand and binder with the disadvantages already mentioned in the region of the reject or discharge opening of a core shooter.
  • the method defined at the outset according to claim 1 provides that the mixture-free region of the mixing device at least temporarily during the mixing process and the mixing-free region of the feeding device located between the mixing device and the core-producing device and the mixture-free region of the sand-storing unit behind the feeding device and before the core or mold making device moistened or kept moist, with the amounts of moisture for each area individually sized and fed.
  • moistening sets in the areas mentioned a high humidity, which can prevent or reduce evaporation or leakage of moisture from the mixture.
  • the mixture can not fully or partially cure or dry or form encrustations.
  • Soiling of the mixing device and the feeder and also the sand storage unit, but also the core manufacturing device so can be reduced and / or the necessary cleaning intervals are extended. This fact can in particular have a positive effect on the productivity of the core production process and, in addition, the cleaning intervals can be extended and the cleaning costs can be reduced.
  • the mixture-free region of the mixing device is at least temporarily moistened or kept moist, at least during the mixing process. Especially by the mixing process moisture could escape from the mixture in the mixture-free area. By moistening the mixture-free area can be easily prevented that moisture escapes from the mixture, it dries on parts the mixing device and soiling the blender.
  • evaporation or escape of moisture from the mixture is reduced or prevented by keeping the humidity above the mixture by supplying moisture, in particular to about 70% to 100%, preferably to about 80% to 100 % is kept.
  • Such humidity values minimize the moisture gradient between the mixture and the air surrounding the mixture, thereby largely preventing the release of moisture from the mixture to the air by evaporation and concomitant undesired curing of the mixture.
  • the serving for wetting liquid or serving for wetting water is atomized by means of ultrasound to a floatable aerosol and the mixing device and the feeder and the sand supply unit is supplied.
  • the aerosol which can be suspended has such small liquid constituents that they can directly evaporate and increase the humidity without first condensing and without condensing as condensate in the mixing device and the feed device and the sand storage unit.
  • the size of the fluid particles produced by ultrasound may be on the order of 0.01 mm or less. At the same time a sufficiently high humidity is achieved, which can prevent the drying of the sand-binder mixture. Both the mixing process as well as the supply and the storage of the Sandbindergemisch can be done reliably.
  • the aerosol or the quantity of this aerosol which can be aerated and the size of the volumetric flow provided with the aerosol can be adjusted by changing the pulse packets delivered by the ultrasound generator (s) and / or by changing the voltage of the ultrasound generator (s). In this way, the amount of airborne aerosol, with which the mixing device and the sand storage unit is moistened, adapt to the existing conditions such as atmospheric humidity, size of the volume to be humidified and ambient temperature.
  • a particularly expedient embodiment of the method according to the invention can be that the suspended aerosol is formed and fed via several lines of the mixing device and the feed device and the sand storage unit.
  • the generation of the aerosol thus happens outside of the mixing, feeding and the sand storage unit.
  • For the preparation of the aerosol so no additional space is needed in the mixing, feeding and the sand storage unit. Nevertheless, it is possible to provide a sufficiently high humidity, so that drying of the sand-binder mixture can be avoided, but without supplying too much liquid, whereby in particular the binder could possibly be washed out or dissolved.
  • the device defined at the outset according to claim 6, characterized in that provided on the mixing device and on the feeding device and the sand storage unit whose inside acting or in the interior of which moistening device is provided, so that the amount of moisture for each area individually - and can be fed.
  • the generation and maintenance of the desired air humidity can be achieved in a particularly simple manner so that the risk of drying due to moisture loss of the mixture in the mixing device and in the feed device and / or in the sand storage unit can be reduced. This can favorably reduce the contamination of the mixing device and the feeder and the sand storage unit, but also the downstream core manufacturing device.
  • the moistening device has at least one ultrasound transmitter in the form of an ultrasonic atomizer for water or for a liquid containing in particular water.
  • the invention thus makes use of the fact or knowledge that with ultrasonic atomizers water or a liquid containing water can be atomized in such a way that the individual droplets can be smaller than 20 thousandths of a millimeter or even smaller than 10 thousandths of a millimeter, so that they change into atmospheric moisture and precipitating hardly or hardly as a moisture film on parts of the mixing device and the feeder and the sand storage unit.

  • a fan or a compressed gas connection is arranged in particular above the liquid surface in the liquid reservoir.
  • a fan or compressed gas connection can improve this flow or also allow a greater distance of the ultrasonic atomizer from the areas of the device to be supplied with moist air .
  • height differences between the ultrasonic atomizer and the said areas of the device at the core shooting device can be overcome by a fan and / or a compressed gas connection.
