Definitions

  • the invention relates to a device and a method for dosing pasty Substances and their mixing with a solvent using an injector integrated shut-off device, the dosing quantity based on a conductivity measurement is detected.
  • Liquid to pasty detergents are known in large numbers. These are in generally matched to household needs, that is, they should be sufficient be liquid and pour and dose easily. Since she also you want to be stable in storage over a wide temperature range usually not without the use of organic solvents and / or hydrotropic additives. However, these additives are wash-inactive, comparatively complex and require additional packaging volume or transport and Storage capacity. In particular, a content of flammable solvents is a problem the comparatively high throughput of detergents in laundries additionally require safety precautions. Detergent concentrates of the type mentioned are therefore of little or no use for laundries.
  • a detergent that meets these requirements is described in EP 0 295 525 suggested. It is a pasty detergent, the special Handling requirements for dosing and mixing with water as Solvent. For the metered feeding and mixing in this Publication with an injector working on the principle of a water jet pump integrated shut-off valve proposed.
  • As a detection device for the dosed The amount of paste is a measuring arrangement based on conductivity measurements disclosed.
  • a chemical dispenser as a dosing device for chemical solutions from unknown or variable concentration in connection with a detection device on the basis of conductivity measurement and a corresponding method is also in the EP 0 229 038.
  • the technical problem underlying the invention is a known one Device, or a method for their operation so that the Shut off the supply of pasty substances and their solvents separately can be such that a dosage corresponding to the mixing ratios of the mixture components precisely, in a simple and reproducible manner and with little effort is possible.
  • the Shut-off device a double control piston for closing an opening separately between paste feed and an injector suction chamber and an opening between Solvent supply and an injector prechamber is as well as by a
  • the method described above which is being developed so that by opening a Shut-off device in a supply line for the pressurized solvent a double spool assembly moves against an opposing force and thereby initially a connection between a paste feed line and injector suction chamber and then a connection between the solvent supply line and an injector prechamber releases, in which according to the principle of Water jet pump working injector paste sucked in and with the relaxing Solvent mixed and the mixture is injected into a measuring section in which a conductivity measuring device the amount of paste dissolved in the mixture determined and closed the shut-off device after reaching the target dosage is, after which the previous opening circuit in reverse order to Locking expires.
  • the metering device has the advantage that by the separate Shut off the paste and solvent supply a targeted, the Mixing ratios that take exactly into account are possible with simple means is. It is particularly advantageous if the paste feeder and then the solvent supply can be released and when shutting off these steps in reverse order. This ensures that over the entire Constant mixing ratios can be achieved.
  • the control device proposed in a special embodiment allows it in simple way, the sequences of the individual circuit steps and their control in effective control and monitoring.
  • the proposed procedure advantageously offers the possibilities of dosing and mixing using an injector and Dosing quantity detection based on the conductivity measurement in one form carry out, which uses the possibilities of these aggregates in optimal form and in simply connects with each other and the objective in an advantageous manner implements.
  • the devices and methods according to the invention are primarily with a view to pasty detergents and their use in washing processes with regard to dosage and Mixing described.
  • water is the most common and preferred Solvent.
  • they are equally suitable for other pasty chemicals and solvents.
  • the illustration of an embodiment for the metering device 1 shows from the right coming the feed line 8 for the solvent, which is usually Water. This is present with increased pressure and is blocked by the shut-off element 9 separated from the dosing device. This has proven to be particularly advantageous Use a 2/2 shut-off valve or tap, in which only between the Switch positions are completely open and completely closed. Is the shut-off device 9 opened, the pressurized water is against the control piston 6, which is on the piston plate 15 is arranged.
  • the piston plate 15 is arranged on a guide plate which in the cylindrical space 10 is axially movable.
  • the room 10 is waterproof overall designed. Below the guide plate, a spring 16 is arranged against which the Guide plate is axially movable.
  • the water under pressure under the injector is on the piston plate 15 next to the arrangement of the piston 6 and presses it down.
  • the spring 16 is designed so that it is at a water pressure of 2.5 is deflected bar.
  • the piston plate 15 moves down, it picks it up her arranged pistons 5 and 6 with.
  • the piston 5 closes the Connection between the paste feed 7 and the injector suction chamber 4 while the piston 6 the connection between the feed line 8 and the injector prechamber 3 cordoned off.
  • the length of the distances and the length of pistons 5 and 6 matched to them is selected so that when the double control piston arrangement 5, 6, 15 drops, initially the connection from the paste feed 7 to the injector suction chamber 4 is released.
  • the water is immediately under full Operating pressure, so in the embodiment below 2.5 bar and presses through the narrow Injector nozzle 2.
  • Injector 2 is through the cylinder space for piston 5 to the Injector suction chamber 4 and the measuring path 13 coaxial therewith.
  • the relaxing water sucks paste from the paste feed 7, dissolves the paste and mixes with her.
  • This mixture is injected into the measuring section 13 in which it by the measuring electrodes 14 spaced apart in the flow direction with respect their electrical conductivity can be measured.
  • This measuring arrangement allows the in the amount of paste present in the mixture to be recorded precisely, so that in their Concentration of unknown or varying pastes can be precisely quantified can.
  • An integration device in a control device determines the amount of the total dosed paste and gives when the target dosing amount is reached the command to close the system. Then the onward transport the mixing of the paste in aqueous solution in the product line 17 interrupted.
  • the guide plate with the on it arranged piston plate 15 and the pistons 5 and 6 after closing the opening for Injector prechamber 3 can only be moved upwards if this is still in room 10 Existing water can be removed via the bypass 12.
  • the after the closure of the Connection to the injector prechamber 3 by the amount of water conveyed is so minor that it does not significantly influence the mixing ratio.
