Definitions

  • the present invention relates to a pressure control, especially for use in connection with the treatment of textiles. More specifically, the present invention concerns passage control devices on pressure containers for treating Wide textile material.
  • pressure containers which are also known as pressure dampers
  • textiles passing through in a continuous manner are at an inner pressure of several atmospheres above atmospheric pressure subjected in a steam or gas atmosphere to a treatment, for instance to a bleaching operation, a bucking operation, or other operations.
  • devices which comprise primarily hydraulically or pneumatically actuated hose-shaped diaphragms which engage the goods passing therethrough from both sides and thus form a separating wall between the pressure in the container and the atmosphere.
  • the pressure in the sealing diaphragrns must exceed the pressure in the container by a very slight amount only, as for instance from 0.1 to 0.5 atmospheres above atmospheric press-ure.
  • the pressure reducers do not respond to the changing roughness and thickness of the pieces of -material sewn together nor to the changing sliding factors of the liquor by which the oncoming goods have been impregnated, As a result thereof, the resistance at the sealing elements and consequently the pulling tension in the goods change while in some instances also steam may escape when the sealing elements no longer withstand the inner pressure of the container.
  • Still another object of this invention consists in the provision of a control device by means of which the various frictional resistances can be properly controlled.
  • FIG. 1 diagrammatically illustrates partly in section a control arrangement according to the present invention.
  • FIG. 2 shows a side view of a portion of FIG. l.
  • FIG. 3 illustrates a slight modification of the fine pressure control in the sealing diaphragms.
  • the arrangement shown therein comprises a pressure damper 1 esigned for a high inner pressure.
  • the pressure damper 1 is provided with ⁇ a device 3 for passing the goods therethrough in a pressure-tight manner.
  • the device 3 comprises two pressure diaphragms 2.
  • the pressure damper l furthermore comprises a plurality of deviating rollers 4 for looping the goods therearound, and also comprises a driving roller system 5.
  • the passage device or control which seals the goods passing therethrough between the two pressure diaphragms 2 is acted upon preferably by a hydraulic pressure.
  • the said hydraulic pressure is furnished by a pump 6 located in a circuit comprising the feeding line 7, the pressure transmitter 8, the return conduit 9, the diaphragms 2, the control throttle 10 and a cooling device 11.
  • the cooling device is necessary in order to be able to cool the termally highly stressed sealing diaphragms 2 through the pressure iiuid circuit.
  • the pressure transmitter 8 comprises a cylinder 8a having reciprocably mounted therein a double-acting piston 12. Piston 12 is acted upon from both sides, namely at one side by the inner pressure of the damper 1 which pressure is conveyed through a conduit 14, and on the other side by the pressure medium in the closed pressure circuit of the diaphragm seals 2 as conveyed through conduit 9.
  • the cross section of pressure piston 12 is so selected that the inner pressure in the sealing lips will be approximately equal to the inner pressure of the pressure damper 1 but will under no circumstances drop below said last mentioned inner pressure.
  • this ne adjustment is effected by a precisely ⁇ adjustable additional load on piston 12, preferably by placing weights 17 upon the piston rod 13 protruding from the pressure cylinder 80.
  • the inner sealing lips are subjected to varying pressure. This would normally, when the goods are pressed to an increased extent, result in an increased tension of the goods in the looped area within the kettle or when the sealing lips press upon the goods to a lesser degree, would result in an escape of steam and thereby in a drop in the pressure. inasmuch as the pressure transmitter 8 operates only in conformity with the inner pressure in the kettle, these influences are not taken into consideration.
  • the inertia-free control of the sealing pressure of the sealing diaphragms 2 is effected by a feeler device which is controlled by the tension of the goods in the interior of the kettle 1.
  • a floating jockey pulley 21 which is carried by a lever 21a keyed to a shaft 23 extending through a pressure-tight bearing 24 and carrying a sprocket wheel 25.
  • Sprocket wheel 25 is by means of a chain 26, a sprocket wheel 27 keyed to a shaft 28, a sprocket wheel 29 and a chain 30 drivingly connected to a sprocket wheel 31 which in its turn is operatively connected to the valve member.
  • the pressure transmitter 8 or the pressure control in the pressure circuit of the sealinU diaphragms which pressure control is controlled by the tension of the goods could also be employed by themselves, but in the second instance no suiiicient safety for a closing of the sealing lips would be obtained when, for instance, due to a disturbance in the movement of the goods, the said floating jockey pulley Z1 fully opens Athe control throttle. In such an instance, in view of a shock-like evaporation it could occur that the pressure damper breaks, aside from the fact that the operator may be endangered by the escaping steam and its eifect.
  • the piston rod 13 is hollow with through bores l5 at the lower end of said piston.
  • the condensate collecting above the piston can pass through said ybores 15 and the hollow rod 13 into a conduit 16 for discharging the said condensate.
  • pressure fluid operable cylinder piston means comprising a cylinder and a double-acting piston reciprocable in said cylinder, first conduit means leading from said vessel into a portion of said cylinder at one side of said piston to convey the fluid pressure prevailing in said vessel to one side of said piston, second conduit means in flow communication with the other side of said piston for conveying pressure fluid to said other side of said piston and from said other piston side to the diaphragm means to thereby control said passage means, auxiliary means operatively connectable to said piston for selectively exerting pressure thereon in the same direction in which said piston reacts to pressure acting on said one side thereof, and control means including i'irst means arranged in said vessel and also including second means operatively connected to said irst means and arranged in said second conduit means and operable in conformity with the tension of the
  • said second conduit means forms a closed circuit including a pump with a suction side and a pressure side and also including a feeding line leading from said pressure side into said cylinder for conveying pressure fluid to said other side of said piston, said second conduit means also including a return line leading from a portion of said cylinder at said other piston side to the suction side.
  • auxiliary means is formed by additional pressure fluid operable cylinder piston means operatively connected to said rst mentioned pressure fluid operable cylinder piston means.
  • control means includes: jockey roller means arranged inside said vessel and adapted to be passed over the material being processed in said vessel, lever means pivotable in said vessel and supporting said jockey roller means, and throttle valve means interposed in said second conduit means and operatively connected to said lever means.
