Definitions

  • Atomizing head for spraying liquids concerns an atomizer for l iquids, l ike water , to be atomized for moistening the atmosphere in spaces, like stores for paper and the like.
  • the atomizer is of the type where the liquid is atomized with the help of compressed gas.
  • the invention has in view a considerable improvement of the operation of these atomizers in such a way that not only the fluid nozzle but also the gas nozzle is cleaned at the moment the atomizer is shut off.
  • the atomizer construction has in normal operation acontinuous waterpressure while the nozzles are cleaned by periodical shut-off of the gas supply without the risk that the atomizer produces a squirt of not-atomized liquid in the atmosphere.
  • the invention will be enplaned with the help of the drawing.
  • Fig. 1 shows a crosssection along the length of the atomizer at rest.
  • Fig 2 shows the fluid nozzle
  • Fig. 3 shows the seal of the liquid supply when gas-pressure is absent.
  • Fig. 1 shows with (1) the housing of the atonmizer.
  • the housing (1) is (2) the liquid supply and with (3) the supply for compressed gas (further-on to be indicated with air).
  • the front is airspray head
  • the airspray head (4) is axial forced with airspray head spring (6) and held by ring (7) which is attached to housing (1).
  • Ring (7) is provided with a. groove that carries sealing ring (8).
  • Flange (9) of airspray head (4) realises with sealing ring (8) a gastight seal between flange (9) and housing (1). Between flange (9) and housing (1) is ample tolerance to permit cleaning by air when the atomizer is put into operation.
  • nozzle (12) In the centre of the housing is a plug (10) screwed-in which carries nozzle holder (11).
  • nozzle holder (11) In this nozzle holder (11) is a nozzle (12) attached.
  • the mouthpiece (13) reaches through air nozzle (5) of airspray head (4) when airspray head (4) is pushed back by spring (6).
  • From the wall of nozzle (12) a part is taken away to form opening (14).
  • cleaning needle (16) In the end (15) of nozzle (12) is cleaning needle (16) located.
  • Cleaning needle (16) has a sliding fitting inside nozzle (12) and can move axial to position (17).
  • Cleaning needle (16) is connected with piston rod (18) which is adjustable connected with screwpiece (19) to the piston (20).
  • Piston (20) is pushed axial by piston spring (21) in the direction of nozzle (12).
  • Piston spring (21) rests against spring holder (22) which is attached in cylinder (23).
  • Spring holder (22) carries in a groove sealing ring (24) which provides a gastight seal between piston (20) and cylinder (23).
  • Piston (20) fits with ample tolerance in cylinder (23"') which allows piston spring (21) in all cases to bring piston (20) in the rest position.
  • housing (1) In housing (1) is provided for a seal (25) through which pistonred (18) can travel axially in housing (1) Housing (1) is provided with an air supply connection (26) that connects gas supply (3)with space (27) . Also in housing (1) is a connection (28)which connects space (27) with cylinder space (29). On the side of space (27) here is a sealing ring (30)mounted in a recess inside connection (28) that seals connection (28) with flange (9).
  • Liquid supply (2) is connected with space (31) with connection (-32) .
  • Space (31) can be separated from space (34)by seal (33) against the screw part of tube-like piece (10).
  • Liquid under pressure is supplied through liquid supply (2) to space
