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.

  • 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.
