Definitions

  • the invention relates to a liquid container of the type corresponding to the preamble of claim 1.
  • liquid containers are known for many applications, in particular in the field of textile finishing.
  • the liquid drain is usually a simple pipe socket with a shut-off valve.
  • a pump is also connected, which supports the emptying. In general, however, it takes a certain time for the conventional liquid containers of the type in question, which can sometimes have considerable liquid contents, until the quantity of liquid is removed.
  • the invention has its origin in problems that arise in connection with modern liquid application devices, as described for example in the unpublished DE-OS 37 33 997.
  • An essential feature of these liquid application devices is that they contain only a very small liquid supply, which is practically consumed in a fraction of a second by the continuous web if there is no replenishment.
  • An advantage of this small liquid supply is that a color change can be carried out just as quickly.
  • switched washing compartments which still contain washed-out color components from the previous batch, are emptied and filled with fresh water or other washing liquid.
  • This change of the washing liquid must, if the possibility of the quick color change, which the application device offers, be fully effective, must take place as quickly as there.
  • the problem is that a large amount of wash fluid on the order of cubic meters must be drained off in a time on the order of seconds.
  • the conventional washing compartments in continuous dyeing systems with their normal drain valves are not designed for this.
  • the invention has for its object to design a liquid container of the generic type with a large content so that the liquid can be drained in the shortest possible time.
  • the size of the closing element controlled by the pressure of a fluid medium or the gap limited thereby can be selected as required and release a flow cross-section which can be a multiple of the flow cross-sections of the usual liquid drains.
  • the liquid "falls" through this gap practically instantaneously out of the liquid container into an underlying collection and discharge arrangement.
  • the closing element is formed by an inflatable elastic sheet, in particular by an inflatable tube (claims 2, 3).
  • the sheet or hose comes under the hydrostatic pressure of the liquid above and / or due to the resilience of their material and open the outlet gap.
  • the sheet or tube bulges out and closes the gap.
  • the gap is formed by two resilient closing elements, in particular hoses, which can be pressed against one another and which can be identical or different from one another (claim 5).
  • the counter element be formed by a fixed wall part (claim 7).
  • the gap between the closing element and the counter element or between two flexible closing elements opens when the pressure of the fluid pressure medium is removed.
  • the sudden opening of a large flow cross section can be supported by a vacuum device according to claim 7, through which a positive opening force is exerted on the closing element or the closing elements by reducing their cross section through the vacuum.
  • the opening can be carried out particularly quickly by means of a vacuum accumulator.
  • the gap formed between the flexible closing elements can extend over a substantial part of the extent of the bottom of the liquid container (claim 9), in particular over the entire bottom in an arrangement according to claim 10.
  • the wash compartment designated as a whole in FIG. 1 consists of a liquid container 1 with an essentially horizontal bottom 2.
  • the liquid container 1 is up to a fill level 3 with washing liquid 4 filled.
  • mutually parallel deflection rollers 5 are provided, which are arranged completely below the liquid level 3.
  • guide rollers 6 are arranged in a horizontal plane.
  • the web 7 is in the usual manner zigzag or meandering in succession over one of the lower and one of the upper guide rollers 5,6.
  • transverse walls 9 are provided in the liquid container 1, which subdivide the total amount of liquid and are provided above their deflection rollers 6, against which a squeeze roller 8 works, which transports the liquid from one of the sub-compartments 11, 12, 13 to the next the web 7 squeezed and can run back into the previous sub-compartment.
  • the washing compartment 10 is preceded by a dyeing liquid application device, not shown, which enables a very quick color change. For this reason, the washing liquid in the washing compartment 10 must also be able to be changed very quickly. However, the amount is considerable; with the usual web width of approximately 2 m and a fill level of approximately 500 mm, the embodiment shown in FIGS. 1 and 2 is approximately three cubic meters.
  • a liquid outlet designated as a whole by 20
  • the liquid container 1 which comprises two inflatable tubes 14, 15 which lie opposite one another in a horizontal plane and extend parallel to the pass plane of the web, each of which over extend the length of the washing compartment 10 and one between them
  • Form gap 16 which, when the hoses 14, 15 are inflated, for example, by compressed air, is closed by the hoses resting against one another on a contact surface 17 shown cross-hatched in FIG.
  • the hoses are resilient and, when the pressure in them is reduced, step back from each other to open the gap 16, which is then widened by the pressure of the outflowing liquid.
  • the liquid can then exit virtually instantaneously through a wide gap that extends over the entire length of the washing compartment 10 into a channel 18 provided under the gap 16 and extending along the washing compartment 10.
  • the tubes 14, 15 are inflated again, as a result of which the gap 16 closes and the liquid container 1 can be filled again.
  • the gap 16 extends over the entire length of the liquid container 1, i.e. across all sub-compartments 11, 12, 13.
  • separate gaps could also be provided for each sub-compartment and the gaps also only extend over part of the length of the individual compartments.
  • An arrangement of the gap transversely to the direction of travel of the web 7 can also be considered.
  • holding members 21, 22 are provided on the side facing away from the gap 16, which have channel-shaped holding members 19 for the hoses 14, 15 on the mutually facing sides leave a space that can be sealed by inflating the tubes 14, 15.
  • the holding members 19 are provided on the mutually facing sides of box-shaped longitudinal members 21, 22, which extend over the length of the liquid container 1 and above the holding members 19, 19 form a funnel-shaped space region 23 which is closed at the bottom by the hoses 14, 15.
  • the bottom plate 24 of the liquid container 1 is substantially flat and inclined towards the liquid outlet 20, so that liquid thereon drains over the top of the box-shaped carrier 21 into the funnel-shaped area 23 and the liquid container 1 can be completely emptied.
  • FIG. 4 shows an outlet 30 with only one hose 25 which can be inflated against a fixed wall part in the form of a downward angled portion 26 of the base plate 24 provided near the side wall 27 of the liquid container 1. Between the bend 26 and the side wall 27 there is an intermediate space which can be closed in a sealing manner by inflating the hose 25. A holding member 28 for the hose 25 is formed in the side wall 27 by a corresponding bulging outwards.
  • the hose 25 can be connected via a connection 29, which is only indicated, and the line 31 and a valve 32 to a vacuum accumulator 33, which can be evacuated by a pump 34.
  • the hose 25 can be pulled back into the position of the cross section indicated by the dashed line when the outlet 30 is opened, and the entire width of the gap 16 can be released immediately.
  • a hose 25 with a diameter of 65 mm and a wall thickness of 3 mm and a hardness of 60 o Shore A was used on a liquid container with a width of 1800 mm and a content of 30 m with a fleet height of 500 mm.
  • the Drainage time of the amount of water of about three cubic meters about 2 minutes, with an outlet 30 extending over the length of the liquid container with the data mentioned, about 15 seconds.
