Definitions

  • the invention relates to a punch press for crushing asbestos containing plate material, such as corrugated, flat and tubular asbestos containing plate material, which punch press comprises:
  • Hydraulic punch presses are known in the prior art and used to punch out a part from for example a metal sheet.
  • the hydraulic punch press is provided with a first tool arranged in the stationary tool holder having a hole corresponding to the part, which is to be punched out of the metal sheet.
  • the movable tool holder is provided with a second tool, which matches the first tool and can slide into the hole of the first tool, such that the desired part is cut out of the metal sheet.
  • a known method is developed in which small particles of asbestos containing plate material are mixed with acid, such that the asbestos fibers are isolated and can no longer cause any health issues. This method requires that asbestos containing plates are crushed into small particles. Up to now, the asbestos containing plates are shredded, but this generates a substantial amount of asbestos containing dust, which is far more dangerous for people than the asbestos containing plates.
  • an asbestos containing plate can be crushed into small particles without the generation of a substantial amount of dust as known in the prior art. Due to the grating-like die and the second tool with corresponding pins, which can be pushed through the holes in the grating-like die, it is possible to break an asbestos containing plate into a large number of particles, which are pressed through the openings in the first tool.
  • the plurality of through holes have each a square cross-section and wherein the pins have a circular cross-section.
  • the asbestos containing plate material As asbestos containing plate material is typically brittle and cannot be cut as metal sheet or plastic sheet, the asbestos containing plate material will break into small particles when the first and second tool of the punch press according to the invention are pressed together. By having square through holes and cylindrical pins, there will be some space between the through holes and the pins, such that the broken parts of the plate material can easily be pushed through the through holes, without jamming the punch press.
  • the width of the square cross-section is at least 10% larger than the diameter of the circular cross-section. This ensures substantial play between the through holes and the pins, allowing for the asbestos containing particles to be pushed through the through holes.
  • the dividing walls between the through holes taper towards the movable tool holder.
  • tapering ends of the dividing walls provide cutting edges which improve the breaking of the asbestos containing plate material into small particles.
  • the tapering ends also improve the breaking of debris material remaining at the stationary tool holder at a next stroke of the movable tool holder.
  • a further preferred embodiment of the punch press according to the invention further comprises a scraper plate arranged parallel to the base plate of the second tool, wherein the pins of the second tool extend through the scraper plate and wherein spring means are arranged between the scraper plate and the base plate, such that the scraper plate is movable along the pins.
  • the scraper plate will be urged on the asbestos containing plate, when the first and second tool are brought together. This fixates the plate, when the pins are forced through the plate.
  • the scraper plate will also flatten and/or break the plate material, after which the plate material is crushed.
  • the scraper plate Upon return of the movable tool away from the stationary tool, the scraper plate will scrape along the pins and clean the pins from any debris of the crushing of the plate.
  • a funnel is arranged underneath the through holes of the first tool to collect particles of asbestos containing plate material crushed by the interaction of the first tool and the second tool.
  • the invention further relates to a method for crushing asbestos containing plate material, such as corrugated, flat and tubular asbestos containing plate material, which method comprises the steps of:
  • the device according to the invention will be used and the method according to the invention will be performed in a controlled environment to reduce any health risks for operators.
  • This controlled environment can be provided by a housing in which the device is arranged or the method is performed. This housing is subjected to a pressure lower than the environmental pressure, such that any asbestos particles will be kept within the housing.
  • the device is arranged in a shipping container, like a 20 foot container, together with a power unit, feed and discharge stations, to provide a mobile unit to crush asbestos containing plate material at building sites and to be able to fill the material in a closed means of transport.
  • a shipping container like a 20 foot container, together with a power unit, feed and discharge stations, to provide a mobile unit to crush asbestos containing plate material at building sites and to be able to fill the material in a closed means of transport.
  • Figure 1 shows an embodiment of a punch press 1 according to the invention.
  • the punch press has press frame 2, which is schematically shown in figure 1 .
  • a stationary tool holder 3 holding a grating-like die 4 is provided at the bottom.
  • four guides 5 extend, along which a movable tool holder 6 can move toward the stationary tool holder 3.
  • the movable tool holder 6 is urged by a ram 7 driven by hydraulic means 8.
  • the movable tool holder 6 has a plate from which pins 9 extend. These pins 9 can be inserted in through holes 10 arranged in the grating-like die 4. These through holes 10 are arranged in parallel rows arranged at a pitch p 1 . The through holes 10 within a row are arranged at a pitch p 2 .
  • Figure 2 shows a cross-section of the punch press 1 of figure 1 .
  • the movable tool holder 6 is movable along the guides 5.
  • a scraper plate 11 is also provided at the guides 5 and springs 12 are positioned between the movable tool holder 6 and the scraper plate 11.
  • the pins 9 of the movable tool holder 6 extend through the scraper plate 11.
  • a funnel 13 is arranged underneath the stationary tool holder 3 such that particles pushed through the through holes 10 by the pins 9 will be collected.
  • Figure 3 shows a detailed view of the punch press 1 according to figure 1 .
  • the dividing walls 14 of the grating-like die 4 and defining the through holes 10 are provided at the top with a tapering end, which contribute in crushing an asbestos containing plate 15.
  • the width w of the square through holes 10 is substantially larger than the diameter D of the cylindrical pins 9, the plate can easily be broken and particles P will not be jammed between the pins 9 and the dividing walls 14, as shown in figure 4 .
