Definitions

  • cg urcthane foam comprises a cylindrical chamber into [22] Filed: Jan. 23, 1974 which the liquids are separately introduced under ⁇ 2] ⁇ Appl 435685 pressure and mixed and ejected from the open end of the chamber,
  • the inlets are axially spaced apart and scparated from each other by a throat that has interference fit with the plunger in the forward position of the plunger.
  • the plunger having for this purpose an elastic [58] Field of Search Z39/ll2, ll5-ll8, 239/l l3, 379 4l4 4l5. 527, 528. 569
  • the present invention relates to apparatus for ejecting a mixture of liquids. and more particularly to ejecting a homogeneous mixture of liquids which must be mixed as nearly concurrently with ejection as possible.
  • the invention has utility in a number of fields. such as the ejection of foam. of highly exothermic mixtures. and of thermosetting resin formulations. It will be disclosed. by way of example. in connection with the ejection of foam. particularly foam of the urethane type.
  • the present invention will be used to eject mixtures in a divided form such as spray or droplets or larger cohesive units. However. it is to be understood that the present invention is also useful for the ejection of mixed liquids in a continuous stream.
  • the present invention is amenable to such applications as spray coating on a solid substrate. caulking by injection of a continuous stream into a joint or seam or the like, the insertion ofinsulation by the ejection of a continuous or particulate stream into a space to be insulated. the formation of shaped bodies of foamed or unfoamed plastics by ejection of a mixture of liquids into a mold cavity. the formation of unshaped bodies'of foamed plastics by ejection of the mixture onto a moving conveyor. packaging such as polyurethane packaging, or other processes which will be obvious to persons having ordinary skill in this art.
  • the present invention is an improvement on US. Pat. No. 3.263.928. Aug. 2. 1966.
  • liquids have been mixed and ejected by separately introducing them into a mixing chamber having an open outlet end. from spaced inlets that open into the chamber at about the same distance from the outlet along the axis of the chamber, in a region of the chamber that is swept by a plunger that in its rearward position exposes the inlets and permits the liquids to flow into the chamber and mix in the chamber and be ejected from the open end of the chamber, and upon movement toward its forward position simultaneously closes all the inlets and then sweeps the remaining mixed liquids forwardly out of the chamber.
  • the aim of such devices is to prevent the retention or accumulation in the chamber of any substantial quantity of the mixture of liquids.
  • These liquids are ordinarily mutually reactive to set up to a solid which would impede operation of the device if not completely purged by the plunger.
  • Another object of the present invention is the provision of such apparatus. which has good distribution of material across the spray pattern.
  • Still another object of the present invention is the provision of such apparatus. in which seepage of the liquids in the closed position is eliminated.
  • Still another object of the present invention is the provision of such apparatus. having improved plunger construction.
  • FIG. I is a side elevational view of apparatus according to the present invention.
  • FIG. 2 is an enlarged cross-sectional view of the valve and ejector outlet assembly of the present invention
  • FIG. 3 is an end view of the rear impinger viewed from the right in FIG. 2;
  • FIG. 4 is an end view of the front impinger viewed from the left in FIG. 2;
  • FIG. 5 is an enlarged fragmentary cross-sectional view of the plunger.
  • a gun according to the invention indicated generally at l. and including a head 3.
  • Conduits 7 and 9 each supplies a different liquid to head 3.
  • Sources of supply for these different liquids under pressure to conduits 7 and 9 are not shown but may take any usual form.
  • An air hose 11 supplies compressed air to an air cap 13.
  • Air cap 13 directs air against and along the exterior of valve nozzle 67 for the purpose of cleaning the front end of the apparatus.
  • com pressed air can be used at a relatively low gauge pressure. for example. about 1 to 10 p.s.i.g. In this way. the accumulation of deposits of reactive material about the outlet of the spray equipment is avoided. This compressed air is not intended to assist in atomizing when spraying.
  • a plunger 15 is reciprocable in head 3.
  • the plunger 15 adjacent its forward or free end is of cylindrical con tour and of uniform external diameter.
  • plunger 15 Adjacent its rear end, plunger 15 carries an adjustment nut I7 screw-threadedly thereon.
  • a coil compression spring 19 bears between adjustment nut 17 and the rear end of a housing 21 carried by the gun and continuously urges plunger 15 forwardly.
  • a piston 23 is slidable in a cylinder formed in the rear of the gun.
  • a hollow tubular sleeve 25 extends forwardly from piston 23 and en compasses plunger I5 to guide and support plunger 15 and also to guide piston 23.
  • Valve 29 is selectively opened and closed by actuation of an actuating button 31 carried by the handle 33 of the gun. Depressing button 31 opens valve 29 to admit compressed air 27 to the chamber forwardly of piston 23, to drive the piston rearwardly until the rear end of plunger 15 contacts an adjustable plunger stop 35 screwthreadedly received in the rear of housing 21 and rotat ably adjustable to advance or retract its forward end thereby to fix the rearmost position of plunger IS.
  • the forwardmost position of plunger 15 is set by manipulation of adjustment nut 17.
  • the forward end ofplunger I is disposed in a mixing chamber 37 within head 3.
  • Mixing chamber 37 has an outlet end 39 and is of substantially uniform crosssectional configuration from end to end thereof. including outlet end 39. In general. it is preferred that mixing chamber 37 and outlet end 39 thereof have a substantially uniformly cylindrical shape.
  • the inlets for the different liquids are generally opposed to each other, in the present invention, the inlets ofthe different liquids, shown at 41 and 43 in FIG. 2, are axially spaced apart lengthwise of the chamber 37, and are separated from each other by the plunger IS in the closed position. In the open position, however, when the plunger is withdrawn to the position indicated for example at ,t' in FIG. 2, then the inlets 41 and 43 both communicate with the mixing chamber and the different liquids can enter and mix therein and exit through the outlet end 39.
  • An annular throat 45 is externally screw threadedly secured in head 3 and can be rotated into sealingly seated engagement against a conical shoulder 46 in head 3 and has a radially inwardly extending annular projection 47 thereon of generally truncated conical cross-sectional configuration that terminates inwardly in a radially innermost surface of throat 45 which has an interference fit with plunger 15. That is, the inner diameter of throat 45 is less than the normal outer diameter of plunger 15. To accommodate this interference fit, the forward end of plunger is comprised by an externally screw threaded metal rod 49 that is surrounded by a sleeve 51 of elastic deformable material having a low coefficient of sliding friction, preferably an elastomer and more preferably an organic elastomer.
  • the outer diameter of the screw threads on rod 49 is greater than the inner diameter of sleeve 51, so that sleeve 51 in turn has an interference fit with rod 49.
  • the threads of rod 49 could have an outside diameter of 0.090 inch. so that they are greater in diameter than the inside diameter of sleeve 51 by 0.005 inch.
  • the inside diameter of throat 45 may for example be 0.0025 inch, i 0.0005 inch, smaller than the outside diameter of sleeve 51.
  • throat 45 and sleeve 51 prevents seepage of liquid past throat 45 in the closed position shown in full line in FIG. 2, and also provides a sweeping or cleaning action of the throat relative to the plunger in both directions of movement of the plunger.
  • the interference fit between sleeve 51 and threaded rod 49 assures retention of sleeve 51 on rod 49; and as the material of sleeve 51 does not entirely fill up the grooves between the threads on rod 49, as seen in FIG. 5, these unfilled spaces permit displacement of the material of sleeve 51 radially inwardly as the sleeve passes through throat 45.
  • Throat 45 is internally screw threaded to receive and retain the radially outwardly extending flange 53 of a rear impinger 55 through which plunger I5 passes.
  • Flange 53 is slotted at 57 to permit liquid from inlet 41 to pass through slots 57, and then through smaller slots 59 to mixing chamber 37.
  • the forward end of impinger 55 is conical and of the same shape as the adjacent face of throat 45, so that the adjacent conical face of throat 45 closes the forward sides of slots 59.
  • Slots 59 are forwardly inclined at an angle of about 20 and are axially offset as seen in FIG. 3 to produce a desirable vortical movement in chamber 37 to promote mixing.
  • a front impinger 61 is provided on the other side of throat 45. with a conical rear end traversed by slots 63 to provide communication for the other liquid from inlet 43 through slots 63 to mixing chamber 37.
  • the rear end of front impinger 61 which is the left end as seen in FIG. 2, is conical and of the same shape as the adjacent face of throat 45 and so that face of throat 45 closes the rear side of slots 63.
  • Slots 63 are rearwardly inclined at an angle of about 20 and are axially offset as seen in FIG. 4, to promote a desirable vortical mo tion for mixing purposesv
  • the provision of impingers 55 and 61 that bear against opposite sides of throat 45 and that have slots cut in their ends adjacent throat 45 with throat 45 closing the slots. greatly facilitates the provision of openings for the passage of the liquids into the reaction chamber, because it is much easier to machine slots in the ends of the impingers, than it would be to provide accurate holes through a cylindrical sleeve.
  • slots 59 and 63 makes it possible to increase the total number of the slots, and this has several beneficial results.
  • increasing the number of slots decreases the cross section of each slot and hence the cross section of the streams prior to mixing and so facilitates the fine division and mixing of the streams.
  • Front impinger 6 is secured to a packing sleeve of elastic deformable material having a low coefficient of sliding friction, preferably an elastomer and more preferably an organic elastomer, such as polytetrafluoroethylene.
  • the rear end of sleeve 65 is loosely disposed in nozzle 67 that is screw threadedly secured in head 3, so that front impinger 61 and the rear end of packing sleeve 65 float together as a unit relative to nozzle 67, with the result that the front end assembly is self-aligning and the problem of maintaining extremely small manufacturing tolerances is thereby avoided.
  • the front end of packing sleeve 65 seals in nozzle 67.
  • a packing sleeve 69 ofa material such as that of sleeve 65 which may be tightened with a pack ing adjustment screw 71 screw threadedly received in a sleeve 73 which in turn is screw threadedly received in head 3.
  • the user of the gun can actuate the device by depressing button 31, thereby opening valve 29 and causing piston 23 to move to the rear until the rear end of plunger [5 contacts plunger stop 35.
  • the forward or free end of plunger moves to the rear of slots 59 and 63. to the position .v in FIG. 2.
  • the different liquids that are supplied under pressure to conduits 7 and 9 rush into mixing chamber 37, where they are given a rotary or swirling movement with resultant shearing and mixing of the streams.
  • the mixing liquids thus move toward and out of outlet end 39 with a largely helical movement.
  • the high kinetic energy of the stream may cause the stream to subdivide into discrete particles or drops, or not. depending on process variables well known to persons in this field. Among these variables is the degree of offset ofthe slots from the axis of chamber 37.
  • plunger 15 cannot carry backward or forward any liquid on its surface. and thus promote even a small degree of undesired mixture ofliquids. because the interference fit between plunger 15 and throat 45 wipes plunger 15 clean in both directions of movement.
  • the forward liquid. that is. the liquid that enters through inlet 43. is the first to enter the chamber 37 upon rearward movement of plunger 15 and the last to leave the chamber upon for ward movement of plunger 15. that is. the slots 63 are exposed before slots 59 and are closed after slots 59.
  • the forward liquid that is. the liquid that enters through inlet 43.
  • the slots 63 are exposed before slots 59 and are closed after slots 59.
  • this is not necessarily undesirable and can in fact even be highly desirable. It is not necessarily undesirable. because if for example the mixture ofliquids forms a poly' urethane and the rear liquid through inlet 41 is the resinous component and the forward liquid through inlet 43 is its activator containing isocyanate.
  • slots 63 are closed later than slots 59 may be highly desirable. as it ensures that plunger 15 in its closed position. to the extent that it is wetted at all. will be wetted with the single liquid from inlet 43. rather than with the reactive mixture that previously filled chamber 37.
