Definitions

  • ABSTRACTzA cleaning apparatus particularly for textile articles, the operation of which comprises the steps of subjecting the mechanically agitated articles in an initial phase to the action of a solvent in conjunction with mechanical action in an enclosed cleaning space, following in a second phase to the action of a pulverized aqueous solution prepared beforehand in a vessel external to said enclosed cleaning space and in which said solution has its water content proportioned and its temperature governed, said second phase being effected in conjunction with preferably reduced mechanical action.
  • the cleaning solvent and aqueous solution allow stains of different kinds to be eliminated.
  • the resulting great dampness of the clothes has many undesirable effects, notably a marking and a consequent shrinking effect, especially if the clothes are heavily charged with solvent or ifthere is a mechanical agitating effect with dropping of the clothes.
  • the apparatus of this invention allows for subjecting the articles to be cleaned to the action of a solvent coupled with a mechanical action and possibly followed by hydroextraction, then to the action of an aqueous solution prepared and checked beforehand in a vessel external to the cleaning chamber by injection of the solution into this chamber in the liquid state but as a spray preferably mixed with air, whereby to so obtain a humid atmosphere instead ofa liquid solution.
  • the mechanical action is varied by modifying the speed of rotation of the drum.
  • this high-pressure airstream is drawn from the cleaning space and recycled through an independent pressurizing and heating circuit.
  • the above-disclosed phases of the process may be followed by heavy rinsing with solvent, and the cleaning may be completed with the aid of a white or nonwhite solvent introduced at a moderate rate, i.e. at a rate intermediate the initial high inflow rate of solvent and the low inflow rate of aqueous solution, and to this end use may be made with advantage of the airstream referred to above.
  • the present invention further relates to such an apparatus that includes a machine comprising a chamber in which the mechanical action is performed, solvent tanks and a solution vessel external to the chamber.
  • the solution vessel includes control means for controlling the humidity and temperature of the solution.
  • a humidity sensor may be provided to vary the mechanical action and most notably the rotation speed of a drum constituting the mechanical treatment device inside said chamber or treatment space.
  • the apparatus may include solution atomizing means positioned in a conduit for leading in air at high pressure and variable temperature, and means for providing a moderate inflow of solvent, likewise positioned in said conduit.
  • the air is preferably recycled through a circuit distinct from the customary condensation and heating circuit.
  • This distinct circuit comprises a heater and a fan or blower and is either entirely separate from the condensation circuit or connected as a branch circuit thereof.
  • the cleaning is also improved by this atomization since there is no danger of impurities being redeposited on the articles after being entrained by the liquid solution, for such impurities are quickly carried away by the ample quantity of solvent which is then streamed through rapidly.
  • Machines of the kind referred to can be simplified and made more readily adaptable to different applications and more easily automated within a cleaning cycle, which can itself be varied to suit such factors as the nature of the component parts of the load to be cleaned and the degree to which they are sullied.
  • the machine is equipped with a single fan which not only performs the known operations of recovering the solvent vapors and ultimately ventilating the loads, but also provides an internal air circulation which is effective during the cleaning operations in introducing pure or activated steam, pure solvent, solvent charged with finish-imparting substances, solution charged with water and soaps, or several of these at once, all of which are atomized into contact with the load to be treated, in different doses and concentrations, as they are discharged into this internally circulating air.
  • the invention likewise relates to apparatus for performing the method modified as hereinbefore disclosed, with interconn ections equipped with power-operated valves, at least at those locations where actuations are frequent in the completion of a cycle.
  • FIG. I is a diagrammatic view showing a first embodiment of apparatus for performing the subject method of this invention.
  • FIGS. 2 and 3 are diagrams of two embodiments of the air recycling circuits ofa machine according to the invention.
  • FIG. 4 is a highly diagrammatic showing of a second embodiment of apparatus according to the invention.
  • FIG. 5 is a schematic detail view of the spraying zone of the apparatus of FIG. 4, and
  • FIG. 6 is a highly diagrammatic showing of an alternative cleaning installation, with its auxiliaries and associated circuits for conveying the cleaning, finishing or other substances.
  • FIG. 1 there is shown thereon a cleaning chamber consisting of a perforated drum 1 rotating about a horizontal axis and a door 2 through which the clothes to be cleaned are inserted.
  • a waste liquid drain orifice 3 At the bottom of the drum is a waste liquid drain orifice 3 and at its top is a surplus humidity or solvent vapor collecting manifold capable of being connected to recovery and deodorization means (not shown).
  • the illustrated apparatus includes a white solvent tank 5, a working solvent tank 6 and a graduated vessel 7 for the cleaning solution, located outside the drum, and a solvent tank 8 connected through filtering means 9 to tanks 5 and 6.
  • a suction dip pipe controlled by a valve 1 l is placed in the white solvent tank 5, and a suction pipe 12 equipped with a valve 13 likewise dips into working solvent tank 6.
  • These two dip pipes 10 and 12 unite into a single conduit 14 beyond the valves 11 and 13.
  • Connected into conduit 14 is a solvent suction pump 15.
  • Conduit l4 divides beyond pump 15 into two pipes 16 and 17, respectively comprising valves 18 and I9, and extending respectively to filtering means 9 and to a distiller 20.
  • a filtered solvent conduit 21 issues from filter 9 and extends into tank 8 which is equipped with a cooler 22 and an overflow pipe 23 for returning surplus solvent to tank 6.
  • Storage and cooling tank 8 has two outlets, to one of which is connected the conduit 24 for delivering solvent under the control of a valve 25 and to the other the conduit 24a which is equipped with a valve 25a and is connected to the top of tank
  • a conduit 30 interconnects the tops of tanks 5 and 6.
  • a recycling pipe 31 embodying a valve 32 connects with overflow 23 in order to return the used solvents to tank 6.
  • FIG. 1 On the left-hand side of FIG. 1 may be seen the vessel containing the cleaning solution 7 which is prepared by combining suitable proportions of ingredients such as solvents, soaps and water stored in containers 33. These ingredients are conveyed into vessel 7 through a feed pipe 34.
  • a suction pipe 35 dipping into vessel 7 connects with pipe 34 and with a pump 36.
  • the delivery end of pump 36 is connected to a pipe 37 embodying a valve 38 and extending up to a sprayer 39 positioned within drum 1 for delivering the solution thereinto.
  • Sprayer 39 is preferably disposed roughly at midheight in drum 1, and to the left thereof, in order that the clothes impregnated with solution should be located below rather than above. This ensures that the clothes are charged with less solution at the top of the drum, where a drying airstream (not shown) is provided to carry away the surplus moisture in the clothes; in addition, the solution drains away easily into exhaust 3 for subsequent recycling.
  • the clothes can thus be impregnated and traversed by a small quantity of solution, enabling highly active concentrations of solution to be used with advantage.
  • conduit 37 branches off into a conduit 40 embodying a valve 41 and returning to the top of tank 70, whereby to agitate the solution in simple fashion, and subsequently into a conduit 44 embodying a valve 45 and connected to distiller to enable the solvent of the cleaning solution to be recovered thereat and conveyed to tank 5.
  • conduit 40 receives a recycling pipe 42 embodying a valve 43, which pipe issues from exhaust 3 and circulates the solution.
  • the vessel 7 includes heating means 46, a thermometer 47, a thermostat 48 and an agitator device consisting in this instance of the circuit 35, 36,41, 40, all of which components are intended to provide and maintain set temperature conditions in the solution.
  • a test circuit 49 permits small offtakes to be made of the gaseous atmosphere prevailing in vessel 7 in order to ascertain its relative humidity.
  • this circuit includes an accelerator, a hygrometer or like device equipped with contact switches for operating as well known on the drive coupling means of a motor for rotating the drum 1, in order to vary the drum rotation speed.
  • the apparatus shown in FIG. 1 functions in the following manner: the valves 13 and 18 are opened and the pump 15 started in order to accumulate working solvent in the tank 8,
  • Valve 25 is then opened, causing the solvent to be poured over the clothes falling and agitating within drum 1.
  • the solvent is recovered by opening valve 32.
  • the cleaning solution is prepared with solvents introduced by opening valve 250 and with soap and water admitted through conduit 34, while at the same time checking the temperature and humidity of the solution.
  • the solution Upon opening valve 38 and starting pump 36, the solution is ultimately delivered into drum 1 by sprayer 39, which sprayer is in the exemplary embodiment described herein located at midheight, on that side of the drum where the velocity vectors are directed downwardly.
  • the solution can be circulated by opening valve 43, and its temperature and relative humidity are in all cases rigorously preset.
  • valves 11 and 18 are opened, pump 15 is restarted and valve 25 opened, thereby causing the cleaning to be completed by streaming through the white solvent.
  • the last step is to rinse the clothes cleaned in the drum and to remove them therefrom.
  • a discharged gas recycling bypass circuit 53 which includes a blower 54 for setting the air under high pressure, a heater 55 and a solution sprayer 56. Circuit 53 embodies easy dismantling features.
  • FIG. 3 shows a duplication of the recycling circuits, obtained by positioning at the discharge means 4 two fans 50a, 50b connected respectively to a circuit incorporating a condenser 51 and to a circuit incorporating the heater 52, which is itself subsequently connected to sprayer 56.
  • This feature of the present invention avoids excessive pressure losses, which restrict the circulation of air and reduce the efficacy of the evaporation it produces on the clothes.
  • the drum can be heated very rapidly at the outset since the air no longer passes over the condenser, thereby increasing also the airflow over the clothes. ln addition, the heating of the drum can be arrested more rapidly by completely shutting off the hot air distribution system, while the recycling circuits hereinbefore described further allow the cleaning machine to be transformed into a rotating dryer by using only the heating circuit.
  • the independent recycling and heating circuit obtained thus makes it possible to provide a delivery of gas at high pressure and variable temperature, resulting in satisfactory atomization of the solution and even in a gasification as a result of the heat and pressure.
  • the embodiment of apparatus shown in FIG. 4 includes numerous parts identical to those in FIG. 1, so that only those differing therefrom will be described hereinbelow.
  • the working solvent tank 6 is replaced by two tanks, of which one 6a contains the working solvent and the other 6b the dirty rinsing solvent.
  • Recycling pipe 31 and its control valve 32 are in this case duplicated in the form of pipes 31a, 31b and valves 32a, 32b.
  • dip pipe 12 and its control valve [3 are replaced by two dip pipes 12a, 12b and their associated valves 13a, 13b.
  • the drum 1 is equipped with the condensation circuit 50a, 51 and the heating circuit 50b, 52 shown in FIG. 3.
  • the inlet to injection pump 36 is connected to dip pipe 35, to which pipe are connected in succession, starting from the pump side, a proportioned liquid feed pipe 34, and, at the same point, a pipe 57 embodying a valve 58 and dipping into white solvent tank 5 and a pipe 240 embodying valves 25a and extending from storage and heating tank 8, and lastly a valve 59.
  • the temperature governing means are not shown in FIG. 4.
  • Injection pipe 37 branches off firstly towards sprayer 56 (see FIG. 5) via a valve 60, and secondly via a valve 61 towards means 62 for delivering solvent at a moderate rate, the function of which will be explained in greater detail hereinafter.
  • Sprayer 56 and means 62 communicate into a common highupressure air delivery conduit 63.
  • Condenser 51 is connected to the drum through a return conduit 64.
  • the filter 9 and distiller are interconnected by a valve-embodying conduit.
  • FIG. 5 provides a schematic detailed showing of the sprayer S6 communicating with the means 62 in conduit 63. It will be appreciated that the airflow will entrain in mist form the jet of solution delivered through sprayer 56 and also atomize the jet of liquid issuing from the means 62. The edges 65 of the outlet of conduit 63 are rounded to avoid damaging the clothes.
  • the apparatus shown in H0. 4 functions in the following manner: the clothes inserted into drum 1 are washed rapidly by streaming thereon a large quantity of filtered solvent conveyed through conduits 24 at a rapid rate from tank 8.
  • the solvent dissolves the stains and is then recovered by opening valve 32a and allowing it to flow through pipe 31a back into tank 60.
  • the clothes are then rinsed by rotating the drum at high speed and opening valve 32b to allow the solvent expelled by the rinsing process to flow into dirty solvent tank 6b.
  • the drum rotation speed is then reduced to obtain the desired mechanical action, and fan 50a is started so as to convey air through conduit 63 at a variable temperature depending on the setting of the heating system 52.
  • the cleaning solution prepared and checked as hereinbefore explained is then atomized in this airstream and is conveyed to sprayer 56 by opening valve 59 and starting pump 36.
  • the amount of solution introduced will vary with the quality of the clothes and the degree of cleaning to be carried out. This quantity remains small since the spraying results in desirable distribution and satisfactory absorption by the textile fibers.
  • the solution provides very effective cleaning since the clothes are not weighted down with solvent.
  • High-speed rinsing is effected with an abundant quantity of filtered solvent by reopening valves and 32a.
  • a special feature of this apparatus enables ultimate rinsing to be effected with a white solvent delivered at moderate rate by starting pump 36 and opening valves 58 and 61.
  • the quantity of white solvent delivered compensates for the quantity of solvent channelled to the distiller in order to maintain a balance in the tanks.
  • the dirty solvent can be dispatched to distiller 20 at any convenient time chosen by the operator.
  • a machine comprising a chamber 1 having a scalable closable access door 2 to an opening in an agitating and rinsing drum which can be rotated either continuously or oscillated to and fro at different speeds, as well known per se, which speeds may be more or less high in order to permit rinsing of the load contained in the drum and undergoing the cleaning operation.
  • the lower part of chamber 1 comprises a drain orifice 3 and the upper part a barrel plate 4 through which the air and solvent vapors flow.
  • Barrel plate 4 is connected to the suction orifice of a case 70 surrounding the wheel 71 of a single fan driven by a motor 72.
  • Case 70 is fonned with a closable outlet 73 communicating with a conduit 51 extending up to an assembly which includes a condenser, a solvent vapors recuperator and a ventilating chimney, followed possibly by an air heater adapted to convey the air at the required temperature to a conduit 64 within chamber 1 that opens out opposite the inlet into the rotating drum, for instance into the opening closed by the door 2.
  • the case 70 further communicates with the inlet pipe 74 into a heater 52 the outlet of which is connected to the inlet of a conduit 63 arranged similarly to the conduit 64 referred to precedingly.

  • the pipe 24 extends up to a discharge nozzle 24b positioned within the conduit 64, whereby the streaming solvent is able to accompany the circulating air and take advantage of its motion and temperature.
  • conduit 83 connects with a pneumatically operated valve 19 positioned at the inlet to a distiller 20 equipped with a suitably supplied and drained steam jacket, and the solvent vapor outlet 26 from distiller 20 connects through a condenser 27, a subsequent separator 28 and a return pipe 29, with the white solvent tank 5.
  • steam may be injected in any proportion and at any selected moment by opening the valve 79, with or without a reduction of the mechanical action on the load in the machine undergoing the processing cycle.
  • the solvent delivered can be caused to pass through the filter 9, or else to avoid the same, by closing valve 18 and opening valve 84, thereby preventing the filter from being unduly clogged by dirty solvent which has been used, for instance, for a preliminary wetting of working overalls, the dirty solvent being returned to tank 6d in conjunction with thorough hydroextraction and a small quantity of less charged solvent for preliminary rinsing before the working solvent is used.
