Definitions

  • the invention relates to a system for metering and mixing of two liquid mixing components, each stored in a container, each container for dispensing a defined amount of the mixing component is associated with a pump, and for mixing the two defined amounts of the mixing components, a mixer is provided ,
  • the WO 01114441 A1 describes a static mixing tube used to continuously react a compound having active hydrogen atoms, such as a polyol, with a polyisocyanate to form a moisture-curing polyurethane adhesive or other urethane polymer.
  • the US 3,097,764 describes a proportioning system for controlling and regulating the volume flow of at least two liquids for mixing and spraying.
  • the invention has for its object to provide a system of the type mentioned above, which allows optimum metering and mixing of liquid mixing components whose dosing ratio between 1: 1 to 100: 1 and whose viscosity ratio between 1: 1 and 100: 1 can be.
  • the inventive design of the system pulsating flow rates of the two mixing components are reliably prevented even if the metering ratio of the components and their viscosity ratio of 1 different or very large.
  • the system according to the invention it is thus possible not only to accurately meter two liquid mixing components, but also to achieve a homogeneous mixture of the two components not only if their metering ratio and their viscosity ratio is 1, but if the metering ratio in the range between 1: 1 to 100: 1 and their Viskosticiansverflältnis in the range between 1: 1 and 100: 1.
  • the same inlet pressures of the liquid mixing components can be achieved when entering the Mischvorhunt by dimensioning the two supply lines. This applies in particular to systems according to the invention, with which always identical mixing components, i. Mixing components of the same viscosity and the same metering ratio, are processed.
  • the mixer is formed by a static mixer.
  • the starting characteristics of the two pumps are matched to one another.
  • a dispenser In the Mischvorhunt a dispenser is provided.
  • This dispenser can be formed by at least one perforated plate, a sieve, a mesh or the like.
  • the plant according to the invention is suitable for processing comparatively large quantities of two liquid mixing components, wherein an exact metering and a homogeneous mixture of the two mixing components can be ensured.
  • Such two-component mixing systems require a constant ratio of the two mixing components with low tolerances of the metered amounts, wherein a homogeneous mixture of the components is realized even with a high viscosity ratio and high metering ratio of the mixing components.
  • FIG. 1 shows a schematic representation of an embodiment of the system 10 for exact dosing and homogeneous mixing of two liquid mixing components, which are each mounted in a container 12, 14.
  • Each of the two containers 12, 14 is associated with a pump 16, 18, which is provided for dispensing a defined amount of the respective mixing component.
  • a supply line 20 is connected at its one end 22 to the pump 16.
  • a supply line 24 is connected at its one end 26 to the pump 18.
  • the second end 28 of the supply line 20 and the second end 30 of the supply line 24 open into a mixing chamber 32 a - as well as FIG. 2 clearly visible, which adjoins upstream of the static mixer 34 in the flow direction of the two mixing components.
  • a dispenser 36 is provided in the Mischvorhunt 32.
  • the two pumps 16 and 18 ensure a constant volume flow of the same over a large viscosity and pressure range of the two stored in the containers 12 and 14 mixing components. It is important that the two mixing components have the same inlet pressures when entering the mixing prechamber 32 in order to prevent unwanted pulsating flow rates, which would result in deficient doses and inhomogeneous mixtures of the two mixing components.
  • the same inlet pressures of the mixing components are determined upon entry into the Mischvorhunt 32 by appropriate dimensioning of the two supply lines 20 and 24 or the same inlet pressures of the mixing components are set when entering the Mischvorhunt 32 defined in the supply lines throttle means 38.
  • the supply lines 20, 24 may have a shut-off device 40.
