Definitions

  • An apparatus for spraying and applying chemical liquid means which comprises a plurality of containers with different chemical liquids, nozzle means for spraying and applying said liquids, mixing chambers interposed between said containers and said nozzle means for mixing said chemical liquids with superheated water, and control means for controlling the mixing chambers to dispense through one nozzle means the chemical liquid of one container only.
  • the present invention relates to an apparatus for spraying and applying at least one chemical liquid, which comprises containers for receiving chemical liquids and also comprises a conduit for conveying superheated water which latter leaves said conduit in the form of a jet containing water and steam, while feeding lines for the chemical liquid or liquids are connected to said conduit.
  • FIGURE 1 diagrammatically illustrates an embodiment of the present invention of an apparatus for successively spraying two chemical liquids by means of a single spray pipe.
  • FIGURE 1a illustrates on a larger scale than that of FIG. 1 and in more details that portion of FIG. 1 which is located within the dot-dash circle thereof.
  • FIGURE 2 illustrates the electric control circuit for the apparatus of FIG. 1.
  • FIGURE 3 shows an embodiment of an apparatus for successively spraying four different chemical liquids through two spray pipes.
  • FIGURE 4 diagrammatically illustrates an embodiment with a twin mixing path, in which one chemical liquid is sprayed through one spray pipe While at the same time a different chemical liquid is sprayed through another spray 1- e.
  • FIGURE 5 illustrates an electric control circuit for use in connection with the apparatus of FIG. 4.
  • any desired mixing ratio can be maintained at high precision without the necessity, in view of the employment of such metering pumps, materially to'increase the cost for the spraying apparatus,
  • each chemical liquid has a separate pump associated therewith and that all pumps will have a control device in common which control device is equipped with a control member for each pump.
  • This common control device is adapted, when turning on one of the control members, to bring about a stopping of all other pump drives and also a starting of the engaged pump drive after a time delay with regard to the turning on time.
  • the temporary delay of the start of the turned on pump drive with regard to the turning on time is provided in order to make sure that after admixing a liquid till the admixing of another liquid, the flow of superheated water will pass in a nonmixed condition through the mixing path and the succeeding conduits thereby effecting a cleaning, rinsing action. Therefore, no residues of the first sprayed liquid which remained in the conduits can intermix with the successively sprayed liquid.
  • control includes means for varying the time delay.
  • FIG. 1 the arrangement shown therein comprises a container 10, for receiving and storing a chemical liquid A, while a container 20 is provided for receiving and storing another liquid B.
  • Both containers are open and thus are under atmospheric pressure only and may, if so desired, consist of corrosion resistant material as, for instance, any suitable synthetic material such as polyethylene or polyester with glass fibers, or polyamide.
  • Liquid A is withdrawn from container 1i) through a suction conduit 11 by means of a volumetrically working pump 12. Interposed in conduit 11 is a shut-off valve 11a and a filter 11b.
  • Pump 12 is drivingly connected to an electric motor 12a to be driven thereby. If desired, also other driving means may be employed, such as internal combustion engines, fluid operable motors or pneumatic operable motors.
  • Pump 12 is preferably a slowly rotating piston pump which is infinitely variable and the delivery of which may be adjusted in a stepless manner from zero to full delivery. Pump 12 delivers the fluid through pressure containers 13 to a mixing path 14. Pump 12 must be able to produce a pressure which is somewhat higher than the pressure of the superheated water flowing in conduit 14b, 14c, 15, 16.
  • the feeding of liquid A into the mixing path 14 takes place via a check valve 14d into a mixing chamber 140.
  • a heating apparatus preferably a so-called through-flow heater, which is not shown and which is provided with a delivery pump.
  • the mixing chamber 140 is, for purposes of obtaining definable flow conditions in the chamber, preceded by a straight pipe 14b and is followed by a straight pipe 14s.
  • the mixture composed of liquid A and the superheated water will at the discharge 14 leave the mixing path and flows through conduit 15 to a spray pipe 16.
  • the free end of spray pipe 16 has connected thereto, a nozzle 16:: from which the said mixture escapes in the form of a jet containing water and water steam.
  • Conduit preferably forms a flexible hose.
  • Nozzle 16a may, if desired, be connected to a fixed conduit or may be designed as an independent mechanically movable nozzle.
  • the second chemical liquid B is withdrawn from container 20 by a pump 22 through a conduit 21 and is then conveyed through a conduit 23 to the mixing path 14.
  • the conduit section 20, 21, 22, 23 is, as far as its parts are concerned, built up in a manner analogous to the conduit system 10, 11, 12, 13, and is provided correspondingly with a shut-off valve 21a, a filter 21b, and a motor 22a.
  • the liquid is fed into the mixing chamber 14c through a check valve 14g.
  • an electric control of the motors 12a and 22a may be employed as shown in the diagram of FIG. 2.
  • the diagram is layed out for a three-phase alternating current with the phases RST and the center point conductor Mp.
  • a depressible key 31 For turning on pump 12, there is provided a depressible key 31.
  • the coil 32a of a relay 32 and the coil 33a of a time delay relay 33 is energized. Energization of coil 32a causes blade 32b to close immediately. This short circuits the pressure key 31. Coils 32a and 33a will remain energized also when pressure key 31 opens. Simultaneously, with the closing of the blade 32]), a control contact 32c is opened and coil 3301 of a time delay relay 33 is energized. As a result thereof, control contact 33b is closed only after a time delay with regard to the turning on point (depressing of key 31). To this end, also relays with adjustable time delay may be employed.
  • a coil 34a of a contactor 34 is energized and closes its contacts 34b, 34c, and 34d.
  • motor 12a starts and pump 12 begins with the feeding of a processing liquid A which in the form of a constant mixture at nozzle 16a is sprayed in the form of a uniform mixture with superheated water while steam is being formed.
  • Coil 42a in addition to receiving current through key 41 also receives current via the now again closed contact 320 and contact 42b. Thus, nothing changes when key 41 is again opened.
  • a control contact 43b closes only after a time delay when the key 41 is depressed. In this way a coil 44a is energized and contacts 44b, 44c, 44d close so that motor 22a again starts.
  • the control of the two pumps 12 and 22 with which, when turning on one pump, all other pump drives are blocked, and with which the delivery of the turned on pump starts only after a time delay with regard to the turning on time, could also be effected in a diiferent way.
  • clutches with delayed turning on action or hydraulic or pneumatic controls and control members may be provided.
  • electromagnetic operable clutches for instance, a single drive motor could be employed for all pumps in common.
  • the apparatus according to FIG. 3 is intended for the spraying of four different chemical solutions C, D, E, and F.
  • the various conduits leading from the containers 50, 55, 60, 65, respectively, through suction conduits 51, 56, 61, 66 to pumps 52, 57, 62, 67, and from there through pressure conduits 53, 58, 63, 68, to the check valves 54, 59, '54 and 69 to a mixing path 70 correspond in a simplified way to the conduits 10, 11, 12, 13, and 14, of FIG. 1.
  • the mixing chamber 700 of the mixing path 70 is provided with two discharge stations 70a and 70b so that the mixture can simultaneously be sprayed by two nozzles 71a and 72a.
  • the mixture at both nozzles is composed of superheated water and one and the same solution selected from the four solutions C, D, E, F.
  • the control for this modification may be designed in a way similar to that of FIG. 2 while the various parts, with the exception of the key 30 have to be provided four times. Furthermore, instead of a single blocking contact, for instance, 42c three serially arranged contacts have to be provided.
  • each pump and the drive of the apparatus for producing superheated water for shifting to full and half speed may be provided so that when working with one jet pipe 71 only, the quantity of fluid sprayed through nozzle 71a will remain constant. It is also possible to provide means which when closing one of the shut-off valves 71b or 7212 will automatically reduce the speed of the drive.
  • a U- shaped mixing path 109 may be provided with a central inlet 109a for the superheated :water and with two dis charge stations 10% and 10% for one mixture each.
  • two different solutions G and H from containers 101 and 105 may through conduits 102, 106, pumps 103, 107, and check valves 109 109g, mixing paths 10911, 1091' and discharge stations 109b, 1090 be sprayed simultaneously, for instance, when the object is passed by the spraying stations.
  • the same working method is realized as with successive spraying of a stationary object with different solutions.
  • the mixing path 109 is provided with check valves 109d and 10% respectively.
  • motors 103a and 107a of FIG. 4 for driving the pumps 103 and 107 respectively may be controlled by a control circuit as illustrated in FIG. 5.
  • the circuit for motor 103a, which drives pump 103, is controlled by key 111.
  • key 1 11 When key 1 11 is moved into its closing position, coil 112a of relay 112 is energized and closes blade 1122 thereby establishing a holding circuit for relay 112 to maintain the same energized when key 111 after being released opens again.
  • Energization of relay 112 also closes the contacts 112b, 112c and 112d so that the circuit for motor 103a is closed and motor 103 begins to drive pump 103.
  • motor 103a is to be stopped, it is merely necessary to open switch 110.
  • the control circuit for motor 107a drivingly connected to pump 107 is arranged in parallel with and is designed analogous to the circuit for motor 103a.
