Definitions

  • the invention relates to a flow mixer for liquid or pasty media, with a mixer pipe mixing elements arranged in a row.
  • Such flow mixers are widely used for mixing and homogenizing substances which are stored separately in two components but must be mixed for processing, e.g. Adhesives, joint sealants, lacquers, dental fillers, etc. These are generally cheap disposable mixers for single use, which can be connected to storage cartridges for the two material components (e.g. according to EP-A 0 121 342).
  • Flow mixers of this type are often intermittent, i.e. operated with intermittent mass throughput. This has the disadvantage that the mixture tends to flow or drip from the free mouth of the mixer tube at the end of a "push", which is particularly the case with relatively low-viscosity media. This reflowing is of course a hindrance to clean work and makes it impossible to dispense certain portions of the mix in a precisely metered manner.
  • EP application No. 0 252 401 by the same owner; case K 112 according to which a discharge device for operating the aforementioned cartridges is designed in such a way that its plunger, which drives the delivery pistons, is automatically removed from the delivery pistons after each feed step is lifted off.
  • the object of the invention is to stop the flow of the mixture immediately at the end of a material discharge in a flow mixer of the type mentioned and thus to prevent the reflow, measures of the type mentioned above being carried out on the cartridge delivery piston and / or on the discharge device by generating a "Backlogs" should be supported by the mixer.
  • This object is achieved according to the invention in that the mixer contains at least parts of a check valve arranged in series with the mixing elements, with a valve body which is directly acted upon by the material to be mixed and a predetermined opening pressure.
  • the check valve therefore only has a closing function and not the task of preventing the material mixture that has already escaped from flowing back.
  • the valve opening pressure to be overcome is practically insignificant in view of the relatively high discharge pressure required.
  • the opening pressure produces the desired reaction against the cartridge, even in the case of relatively low-viscosity media whose flow resistance in the mixer is low.
  • the valve also prevents uncontrolled ones Creeping currents inside the mixer during the dormant periods, which could result in local inhomogeneities in the mix - especially when the components have different viscosities. From this point of view, it may be appropriate to arrange the check valve at the mixer inlet - instead of at the end of the mixer tube.
  • valves at the outlet mouth in order to avoid dripping of liquid.
  • valves there is no interaction with a mixer or with cartridges and their contents, and a back pressure caused by the valve is then even undesirable.
  • All of the flow mixers 1 shown are so-called disposable mixers made of plastic, such as those used in connection with double discharge cartridges.
  • a number of mixing elements are lined up longitudinally in a mixer tube 2 and are held immovably, here in the form of only schematically illustrated mixing spirals 3, which are wound alternately clockwise and counterclockwise and are mutually offset in the rotational position.
  • a check valve in the form of a ball valve 10 is in the mouth area of the mixer 1, i.e. adjoining the mixing elements 3.
  • a tubular valve housing 13 is preferably permanently attached to the front end of the mixer tube 2, for example glued or welded or screwed on.
  • the tapered mouth 4 of the mixer tube serves as a valve seat for the spherical valve body 11. This is under the action of a prestressed valve spring 12, which is supported on a collar surface inside the housing 13.
  • the valve housing is provided with a mouth 14 designed as a discharge nozzle.
  • the check valve 10 axially adjoining the mixer tube 2 as shown is normally closed, specifically with an opening pressure which is determined by the pretensioning of the valve spring 12. Material mixture present in the interior of the mixer tube 2 can therefore not escape or drip unintentionally. If material discharge is to begin, the material in the mixer is pressurized from the mixer inlet (on the right in FIG. 1). This pressure overcomes the above-mentioned opening pressure of the valve 10 or the valve spring 12 by direct action on the valve ball 11 by the mixture, so that the ball shifts to the left and the material mixture can escape past it through the nozzle 14. The path of the valve ball 11 is limited by stop pins 15 which are integrally formed on the nozzle 14. If the discharge pressure drops, the ball 11 returns to the closed position through the valve spring 12 and the material flow is stopped immediately, the resultant Overpressure acts backwards against the mixer inlet and a connected cartridge (not shown) and reduces it.
  • the check valve 10 could of course also be designed as a plug valve with a valve plug instead of the ball 11.
  • the check valve 20 is likewise arranged in the mouth area of the mixer 1 adjoining the mixing elements 3, but is installed in the interior of the mixer tube 2a.
  • the check valve 20 is designed as a diaphragm valve, the upper half of the figure showing the valve closed and the lower half opened during the material discharge in the direction of the arrow.
  • an axially arranged, conically tapered flow body 21 which is centered and held in place by four protruding spokes 22 in the mixer tube.
  • the body 21 could also be formed on the foremost mixing spiral 3.
  • a membrane 23 made of rubber-elastic material with a central passage opening which is somewhat smaller than the diameter of the body 21 as a valve body.
  • the diaphragm valve When the diaphragm valve is normally closed (upper half in FIG. 2), the diaphragm 23 lies against the body 21 with its opening edge under elastic pretension. This in turn results in a predetermined opening pressure which prevents material present in the mixer 1 from escaping. When opening material, this opening pressure is overcome, the membrane 23 is lifted from the body and deformed into position 23 '(lower half in Fig. 2), and the material mixture can exit through the nozzle 5.
  • the elastic pre-tensioning of the valve membrane causes the valve to close immediately when the discharge pressure decreases, and the back pressure affects the backflow.
  • the two following exemplary embodiments relate to currents Mung mixer 1, in which a check valve is arranged in the entrance area, ie the mixing elements 3 in advance.
  • the nozzle 6 of the mixer tube 2b is screwed to the mouth 51 of a double cartridge 50, which mouth has two discharge channels 52, 53 for the two material components to be mixed.
  • the check valve 30 is a cone valve with a fixed valve seat disc 35 and a movable valve cone 31. The latter is axially movably guided by four guide tabs 32 in the mixer tube and against the valve opening by the prestressed valve spring 33, which is supported on a collar surface 34 the disc 35 held.
  • the operation of the check valve 30 is practically the same as in the previous examples, but the material is already prevented from passing from the cartridge 50 into the mixer 1. Above all, any "creeping" flow inside the mixer 1 or in the mouth area of the cartridge is prevented when the valve is closed.
  • a poppet valve is provided as a check valve 40 in the inlet area of the mixer.
  • the valve 40 namely the movable valve plate 41, belongs to the mixer 1, while the valve is completed by the flat end face of the cartridge opening 51, with which the seat surface 44 of the valve plate interacts.
  • the valve plate 41 has, on its back, integrally formed, curved spring tabs 42, which are supported on the inside of the mixer tube on the collar surface 43. As a result, the valve disk is held under prestress against the end face of the mouth 51, as a result of which the valve normally remains closed.
  • valve plate 41 Only with increasing discharge pressure of the material components from the cartridge 50 does the valve plate 41 move back (to the left in FIG. 4), and both discharge channels 52 and 53 are released simultaneously for the material transfer into the mixer 1. The closure too Both channels at the end of a partial discharge are carried out simultaneously by the valve plate.
  • the material transfer from the cartridge to the mixer controlled by the non-return valve it is ensured that, even if the material components to be mixed differ greatly in viscosity, their volume ratio is exactly maintained when the material is transferred; If there was a permanently open connection between the cartridge and the mixer, a diffusion between the two components or even a "shift" due to unequal thermal expansion could occur during longer pauses in the discharge, which would at least locally disrupt the desired quantity ratio required for proper use.
  • the valve according to FIG. 4 also prevents a (very undesirable) backflow of material mixture into the cartridge, which could occur, for example, as a result of a reduction in volume when the contents of the cartridge cool down during the discharge pauses.
  • the valve arrangement at the mixer inlet not only prevents the actual "reflow", but also premature material outflow from the cartridge when the still empty mixer is put on.
  • connection between the channels 52 and 53 remains interrupted by the movable valve member 41 during the pausing intervals (closed valve).
  • the two material components are prevented from undesirable mutual contact within the cartridge during the pausing or before entering the mixer.
  • a permanent, effective diffusion barrier between the material components stored in the cartridge it can be expedient to make the separation 54 double-walled into the cartridge mouth.
  • the check valve 60 is designed as a slide valve and is installed in the mouth area of the mixer 1, ie between the last mixing spiral 3 and the discharge nozzle 5a in the mixer tube 2d.
  • a valve body is a cylindrical, provided with longitudinal slots 62 valve slide 61 in a guide 9 of the mixer tube longitudinally.
  • a compression spring 63 which, in the absence of discharge pressure, holds the valve 60 in the closed position shown.
  • the spring 63 immediately returns the slide 61 to the closed position and the material outlet is blocked. Since the head of the valve slide 61 (provided with stop ribs 65) is “torpedo-shaped”, as shown, in accordance with the internal shape of the nozzle 5a, the volume between the slide and the nozzle mouth is kept small, and when the slide 61 moves back, it exerts a suction effect, whereby the nozzle orifice is freed from the material mixture.
  • valves can in principle also be arranged at the other end of the mixer than shown in the exemplary embodiments.
  • the most suitable type and arrangement of valves depend on the media to be discharged and the particular purpose. In general, it can be said that the valve arrangement following the mixing elements tends to be indicated at low viscosities of the material mixture, whereas the arrangement at the transition from the cartridge to the mixer is indicated at higher or strongly different viscosities of the two components.
