Definitions

  • paint booths which are produced according to various designs.
  • the operator is located inside the cabin. He is therefore not effectively protected, and he must wear a mask, which makes work difficult and very depressing.
  • the safety of the operator working in such conditions depends on the greater or lesser possibility of removing the harmful solvents contained in the paints, and the vapors of which are released in the cabin. To meet safety requirements, it is generally sufficient to provide a constant and sufficient air speed in the cabin.
  • the present invention proposes to provide a device ensuring a predetermined adjustment of the speed of the air entering an enclosure, for example in a paint booth, the speed i air being, in this application, adjusted according to the material dimensions to paint.
  • the invention relates to a device ensuring a predetermined adjustment of the speed of the air admitted into an enclosure, comprising at least one introduction of hot or cold air pulsed by a fan, this device being characterized in that it comprises means ensuring the control of the speed of the air delivered into the enclosure, means for varying the speed of rotation of the fan, at least one extractor ensuring the evacuation of the air from the enclosure, and means controlling the pressure prevailing in the enclosure and regulating the speed of the extractor, so that the extraction of air from said enclosure is adjusted automatically according to the determined volume of air introduced into the enclosure.
  • the means ensuring the control of the speed of the air supplied into the enclosure are positioned in the air passage circuit, the speed being displayed on an indicator dial provided with a preset, depending on the desired speed.
  • said speedometer with pre-display directly and automatically controls a variator ensuring the adjustment of the speed of the intake fan to the desired value.
  • the single figure of the drawing schematically represents a a paint booth provided with a device according to the invention.
  • this paint booth is in the form of a closed enclosure into which is introduced the material to be painted, for example a vehicle or the like.
  • the roof of this cabin is provided with a box 2 open on the enclosure, and into which hot or cold air is pulsed by a fan 1.
  • the box 2 can be placed anywhere in the cabin.
  • an air speed control device 3 of the type currently available on the market, is placed in the air circuit and which transmits the values of the speeds which it detects to an indicator dial 4, having been set beforehand (pre-display) according to the desired speed, which, in this particular application, is a function of the volume of the material to be painted introduced into the cabin.
  • the intake fan 1 is driven by a motor 7, by means of a variator 6.
  • an adjustment lever 5 is provided, making it possible to manually modify the speed of rotation of the fan, in order to adjust this ring to a value corresponding to the value of the pre-displayed speed (setpoint) on dial 4.
  • the device makes it possible to precisely regulate the speed of the air introduced into the enclosure. It is also essential that this speed be stable, and for this purpose, the invention provides means making it possible to control the extraction of the air admitted via the fan 1.
  • the invention therefore provides, for this purpose, an extractor fan 10, driven by a motor 11 via a variator 12, and taking air from the enclosure (in this application example, this air is loaded with solvent vapors), to evacuate it to a chimney.
  • the device further comprises an apparatus 13 ensuring the control of the pressure prevailing in the enclosure.
  • This device 13 is designed and produced so as to automatically regulate the speed of the fan 10 by controlling the variator 12, or any other equivalent means. It is thus possible to adjust the extraction of air from the enclosure as a function of the volume of air introduced into the enclosure.
  • the variator 12 can be controlled manually, by any known means.
