Definitions

  • the invention relates to a device for foaming a treatment liquor in a mixing chamber used for foaming or foaming, with means for fine foaming connected to the chamber outlet.
  • liquid liquor in the device is to be fed to the liquor inlet of the chamber and foamed with separately supplied compressed gas, preferably compressed air.
  • chemicals and / or dyes should be foamed in sufficient quantities so that a textile web or the like is to be coated with the foam continuously in a uniform application quantity over the full width of the web and in the direction of travel.
  • the fineness or vesicle size of the foam should be adjustable independently of the amount of foam produced per unit of time.
  • the mixing chamber filled there with glass balls is supplied with liquid treatment liquor and compressed air from opposite sides.
  • the fineness of the foam to be achieved in the mixing chamber is not sufficient to fulfill the treatment task.
  • the foamed liquor in the mixing chamber is fed to a device for mechanical fine foaming.
  • a shaft with radially projecting rods is rotatably mounted in a hollow cylinder, which has rods on the inner surface which are directed radially towards the shaft.
  • Such a device must be manufactured with great precision and stability if it is to deliver the desired success without problems.
  • the object of the invention is to provide a device for producing foam which does not have any moving parts, i. , to create a static foam generator, with the aid of which foam of any fineness in the desired quantity can be obtained without great investment and operating costs.
  • the solution according to the invention for the device mentioned at the outset with a mixing chamber used for foaming is that a pipeline filled with static means for mixing and dividing the foamed liquor is connected to the chamber outlet.
  • a packing contained in the pipeline can consist of a large number of sections of sharp-edged small particles that are small compared to the dimensions of the pipeline, such as sections or breaks in tubes, in particular made of glass.
  • a packing contained in the pipeline can consist of a large number of sections of sharp-edged small particles that are small compared to the dimensions of the pipeline, such as sections or breaks in tubes, in particular made of glass.
  • be provided Preferably, to the to FeinverCumen ne "pipeline laid see a per se known devices for fraktio ⁇ ned distilling filling Glasröhrenab ⁇ cut - so-called Raschig rings - containing When in the mixing chamber more or less foamed liquor in such in the longitudinal direction of the pipeline on.
  • the foam bubbles already present are repeatedly divided at the edges and mixed with one another and with the air contained in the mixture.
  • the pressure is increased in turn, the original spherical foam becomes so-called polyether foam, provided that the starting solution naturally contains a foam stabilizing agent.
  • the fineness of the inventive foam to be produced may further 'invention be amplified simply .dier accordance with that measured in the flow direction of the foam packing length in the pipe and, of course Rohr ⁇ line be extended itself.
  • the liquid liquor is fed to a liquor inlet of the chamber and foamed with separately supplied pressurized gas by the fact that the pressurized gas feed line extends into the region of the liquor inlet of the chamber and that the outlet of the pressurized gas feed line includes a spray head essentially has finely divided gas jets directed in the direction of flow of the fleet to be fed.
  • the spray head should preferably consist of fine-pored material, in particular of a sintered body with continuous pores.
  • the mixing chamber itself can also be filled with static means for mixing and dividing the liquor foamed on the spray head.
  • static means for mixing and dividing the liquor foamed on the spray head.
  • FIG. 1 shows a foaming device in cross section.
  • FIG. 2 shows a foaming device with a shunt.
  • a mixing chamber 1 with liquor inlet 2, compressed gas inlet 3 and mixture or foam outlet 4 is shown schematically.
  • a microstatic means 5 for mixing and dividing the foamed liquor filled pipeline 6 is connected to the latter.
  • the mixing chamber 1 can be foamed in the arrow direction 7 via a pump, not shown, to the fleet inlet 2, the liquor to be foamed, with compressed gas, in particular compressed air, supplied via line 3 in the direction of the arrow 8.
  • compressed gas in particular compressed air
  • a package consisting of a large number of small sections of tubes or fragments of tubes, in particular of glass, which are small compared to the dimensions of the pipeline, intended.
  • These static means 5 for fine foaming should be designed in such a way that they let the foam pass easily in the longitudinal direction 11 of the pipeline 6, but on the way they frequently pass back and forth and cross and constantly break up on sharp edges.
  • the associated foam outlet 4 of the mixing chamber 1 is preferably closed with a sieve 12.
  • the mixing chamber 1 can also be partially or completely filled with the static means 5 or similar particles for finely distributing the foam produced in the liquor inlet area 9.
  • the fineness of the foam to be produced with the device according to the invention depends solely on the length of the pipeline 6 with otherwise unchanged parameters, it may be expedient to change the length of the pipeline 6 alone in order to adjust the fineness of the foam to the respective requirements adapt.
  • the pipeline contains one or more shunts 13 according to FIG. 2 with, for example, a 2-way valve 14. With the aid of a corresponding cascade circuit, any desired fineness of the foam can be achieved without any significant outlay.
