Definitions

  • the present invention relates to devices for spraying water jets, useful in particular for the hydraulic bonding of fibers in nonwovens.
  • This binding consists of sending a curtain of pressurized water jets onto a sheet of fibers to entangle them and form them into a coherent sheet, without requiring the use of binders or resins. It is also possible to bind sheet material such as textile complexes, threads, paper, fabrics, knits.
  • a device for projecting water jets comprising a body delimiting a chamber for receiving a filter.
  • the chamber opens, with the interposition of a perforated plate creating the jets of an appropriate diameter, on a main face of the body and, by an opening that can be closed by a first removable plug, on the side of a front face of the body.
  • the perforated plate is slidably mounted in a through housing, through a hole which can be closed off by a second plug, on the side of the front face of the body.
  • the invention aims to simplify the manufacture of a device for projecting such water jets, as well as to facilitate the replacement of the perforated plate and the filter when they have to be replaced both or only from the perforated plate.
  • the opening and the hole open into the same well formed in the body and provided with a counter-opening and a counter-hole opposite the opening and the hole. respectively, and a pin is removably inserted into the well in the holes of the plugs, so as to keep the two plugs in the closed position when it is fully inserted therein.
  • the perforated plate can be replaced by sliding the pin parallel to its longitudinal axis so that it comes out of the hole made in the second plug while remaining in the hole made in the first plug, so that the plug intended for the the filter remains in place. However, if you also want to replace the filter, you remove the pin further.
  • the walls of the single well maintain a single pin which holds the two plugs. The plugs are removed by removing them respectively from the opening and the counter-opening and from the hole and the counter- hole.
  • first means block the pin in the position where it keeps the two plugs in the closed position and second means block the pin in an intermediate position where it keeps the first plug in the closed position of the opening and stops holding the second plug in the closed position of the hole.
  • the first and second means consist for example of respective peripheral grooves formed on the outside face of the pin and cooperating with a removable finger penetrating radially into the grooves and being able to be operated manually from the outside.
  • the pin acts on a command of a device for supplying water under pressure. of the chamber by authorizing the supply only when it is fully inserted into the well.
  • the pin may constitute the operating member of a switch of an electric circuit for controlling the water supply device or its displacement can send a signal to a control unit which controls the water supply device.
  • the single figure of the appended drawing is a partial sectional view on a 1/3 scale, with the exception of the water supply, of a device for projecting water jets according to the invention.
  • the device for projecting jets comprises a parallelepipedic body 1 having two opposite faces 2, 3, two opposite small faces which do not appear in the drawing and which are arranged in planes parallel to the drawing plane and two faces 4 opposite fronts of which only the right one appears in the drawing.
  • the body is made of steel.
  • an oblong chamber 5 of circular cross section and axis XX ' which goes from one front face 4 to the other.
  • a cylindrical filter 10 of the same shape as the chamber 5 but of smaller diameter.
  • the face 3 of the body consists of a jaw 11 which is screwed to the rest of the body 1 by screws.
  • a slot-shaped channel 12 extending over one generator or over two adjacent generators of the chamber leads from the chamber 5 to a slot-shaped opening 13 formed in the face 3 and opening to the outside.
  • the jaw 11 delimits a cavity in which is housed a plate 15 perforated with microperforations whose diameter is between 50 and 500 ⁇ m and preferably between 100 and 200 ⁇ m, which makes it possible to form jets or needles of water. These perforations are arranged in a row or in two rows parallel to the axis XX ′ and facing the slot 12.
  • the perforated plate 15 is slidably mounted parallel to the axis XX 'in a housing 16 delimited in the body 1.
  • the chamber 5 opens on the side of the front face 4 of the body via an opening 17 in a bore 18 drilled in the body 1.
  • the opening 17 can be plugged by a first plug 19 provided with a hole through which a pin 20 passes penetrating the hole 18.
  • a second plug 21 blocks the opening 22 of the housing and has a bore through which also passes a section 23 of the end of the pin 20 which is narrower than the rest of the pin 20.
  • the opening 17 is formed in the body 1 a counter opening 24 of the same dimension, which is located on the other side of the well, and in which the first plug 29 extends.
  • the hole 22 is formed a counter hole 25, in which extends the second plug 21.
  • Each plug is provided on the outside with a lever 26, 27 allowing it to slide easily parallel to the axis XX ′.
  • a finger 30 which can be operated by hand passes through the wall of the well 18 and its end can penetrate into one of the grooves 28 or 29 when the groove is opposite the finger and thus lock the pin in position.
  • the finger 30 enters the groove 28, the pin is locked so that it maintains the first and second plugs 19 and 21 in a closed position of the chamber 5 and of the housing 16 respectively.
  • the groove 29 comes opposite the finger 30.
  • the finger 30 is then brought back inside the well.
  • the pin is then locked in a second position in which it continues to hold the first plug 19 but it releases the plug 21 which can be removed by the counter-hole 25 and thus access the perforated plate 15 to replace it.
  • the pin 18 When finally the pin is completely removed from the bore 18, it ceases to hold the first plug 19 which can be removed with the possibility of accessing the filter 10 and removing it through the counter-opening 24.
  • the pin 18 has a handle maneuver 31 facilitating its maneuver and there is an electric line 32 which sends a signal to the control device 9 when the pin 18 is not in the position, shown in the figure, of complete insertion into the well 18 where it holds the two plugs 19 and 21.
  • the plug 21 may possibly be part of the body 1 or of the jaw 11.
