Definitions

  • the invention relates to a device for homogenizing flowable Fabrics, with a homogenizer and with an inlet area through which the substances enter the homogenizer.
  • Homogenizers are among others in pharmaceutical, cosmetic, chemical and food industry for the production of creams, ointments, Pastes, mayonnaises and similar products used. They are common arranged at the bottom or below a mixing container in which the Substances are mixed and homogenized.
  • the homogenizer is common designed as a rotor-stator dispersing machine, but can also be a so-called Circulating agitator to achieve a better pumping effect. On such a homogenizer is known, for example, from DE 195 37 303 A1.
  • the invention has for its object a device of the beginning to create the kind that is a simple and safe admixture of Allows substances to the mix or container content, in particular also a safe feeding of difficult to mix components like Powders, liquids, hot fats, or the like.
  • the invention solves this problem in that the inlet area one Current limiters for controlling the inflow of flowable substances into them Has inlet area and that between the current limiter and homogenizer a device for admixing substances to the inlet area flowing flowing materials is arranged.
  • a homogenizer is any facility that uses kinetic energy achieved a mixing and / or homogenizing effect.
  • the homogenizer can be designed as a rotor-stator dispersing machine, which the Kinetic energy of the rotor primarily through a strong shear and Swirling energy is converted into a dispersing effect and thus an intense Homogenization achieved. Because of this dispersing effect, they produce Rotor-stator dispersing machines only have a relatively low pumping effect, so that high drive energies may be required.
  • a rotor-stator dispersing machine instead as a homogenizer, for example a so-called agitator to use that the kinetic energy of the rotor in the first place in a Pumping action and thus in kinetic energy of the goods to be homogenized implemented and has only a low dispersing effect by swirling.
  • a rotor-stator dispersing machine instead as a homogenizer, for example a so-called agitator to use that the kinetic energy of the rotor in the first place in a Pumping action and thus in kinetic energy of the goods to be homogenized implemented and has only a low dispersing effect by swirling.
  • Intermediate stages are also possible, it is conceivable, for example, on Rotor of a rotor-stator dispersing machine to attach additional blades to improve the pumping action, as taken in itself from DE-A-34 17 242 is known.
  • the use of a known from EP-B-0 290 033 Homogenizer is conceivable
  • the homogenizer has an inlet area through which the substances in enter the homogenizer, d. H. through which the pump wings and / or Dispersing devices are supplied.
  • the entry area can be part a mixing container or boiler, on the bottom of which the invention Device is arranged.
  • the entry area For example, be part of a pipe section or flange that the inlet of the Homogenizer connects to the mixing container. In any case, it is is a spatially limited area in the flow direction of the flowable substances or the mixed material arranged in front of the homogenizer is.
  • the inlet area has a current limiter for controlling the inflow of the mix in this inlet area.
  • a current limiter in the sense the invention is any device operating under given operating conditions (Type and set power of the homogenizer, quality (in particular viscosity) of the material to be mixed, pressure inside the mixing container and height of the column of mixed material resting on the inlet area; this The list of relevant operating conditions is not exhaustive) essentially constant and defined inflow of mix in causes the lead-in area. It can be a purely passive one Act current limiters, such as a constriction or other cross-sectional narrowing preferably in the area of the entrance to the inlet area. However, the current limiter is preferred as a device for actively conveying the flowable materials (e.g. a vane pump) or has such a facility.
  • a device for admixing substances to the mixed material flowing through the inlet area is provided. It is about preferably around a feed line that opens into the inlet area and by the other substances (in particular powders, granules or the like) can be mixed into the mix. This meddling can be done continuously or in batches. The interference immediately before the homogenizer ensures that immediately afterwards an intensive Mixing and homogenization takes place in the homogenizer. Thereby clumps or nests of added substances in the mix are avoided.
  • the essence of the invention lies in front of the entrance of the homogenizer to provide an inlet area and the mix in this inlet area flow under largely defined and little fluctuating conditions allow.
  • the one arranged in the area of the entrance of the inlet area Current limiter ensures that the flow conditions in the inlet area only slightly influenced by the operating conditions in the boiler be, so that this inlet area from what is happening in the mixing vessel to one is "decoupled” to a certain degree. It is particularly preferred if in this inlet area due to the suction effect of the homogenizer and a pressure is set by the influence of the current limiter, which under the average internal pressure of the connected mixing container lies and under the pressure in the supply line for the powder, granules or similar.
  • the current limiter can only be an obstacle to flow such as have a cross-sectional constriction, but preferably (Alternatively or additionally) a facility for active funding of the mixed material, which is designed, for example, as a propeller pump or the like can be.
  • This conveyor can have its own drive, in terms of their delivery capacity to the operating conditions and the desired Adjust pressure conditions in the inlet area.
  • it can For example, be connected to the axis of the homogenizer so that its speed is proportional to the homogenizer speed. To this end an extension of the homogenizer axis can extend axially through the inlet area extend through.
  • Such an active conveyor is a current limiter in the sense of the invention since the active conveying of mixed material in the inlet area in a certain quantity at the same time represents a limitation in the sense that a further Inflow of mixed material does not take place. So the goal of the Invention achieved largely defined operating conditions in the inlet area by ensuring a largely constant inflow cause.
  • the clear cross section of the inlet area preferably widens from Current limiter towards the homogenizer. This cross-sectional expansion causes that the mix flow breaks up, and thus the surface increasing droplet formation takes place and so the mixing of additional Substances such as powders or granules are made considerably easier.
  • the pressure set in the inlet area often becomes lower than that Be atmospheric pressure, especially when the powder is depressurized Funnels or the like are to be supplied.
  • the suction power of the homogenizer and / or of a second current limiter described below is higher than that Inflow set by the current limiter into the inlet area.
  • the suction power is the delivery rate of the homogenizer that this would have a pressure at the homogenizer inlet, which is without the current limiter would set. According to the invention, this can be done in the inlet area selectively set a certain vacuum.
  • Homogenizers often only have a low pumping or delivery rate and therefore only a low suction power.
  • a second current limiter between the admixing device for powder, granules or the like and the homogenizer is arranged which is preferably as a device for active funding which has flowable substances.
  • the defined operating status of the inlet device is in this case between the two current limiters set, their operating conditions can correspond to each other be coordinated.
  • the suction power of the second current limiter becomes frequent again higher than the inflow permitted by the first current limiter be so that there is a corresponding negative pressure.
  • the second The current limiter can have, for example, pump blades that rotate on the homogenizer axis are arranged, in particular on the hub of the homogenizer can be arranged.
  • powders are particularly preferably mixed in Powder valve is used to open and close the powder supply.
  • suitable Powder valves are familiar to the person skilled in the art, for example they can be used as ball valves, Piston valves or the like may be formed. It is preferred that the powder valve in the closed state the device for admixing of powders in the area where the mouth ends in the inlet area. This means that when the powder valve is closed there is no or at most a small area of the feed line for powder from the inlet area is accessible here, so that a kickback of liquid in the supply line does not take place or only to a very small extent can. This avoids that in an end region of the supply line forms a graft of powder and mixed material in front of the inlet area.
  • the device according to the invention has an overall number 1 Homogenizer and an inlet area 2.
  • the homogenizer 1 opposite end of the inlet area 2 has a flange 3 for connection preferably on the bottom of a mixing container.
  • the homogenizer 1 has a shaft 3 provided with a hub 4, the rotary motion of a drive, not shown in the drawing can be moved.
  • a rotor 5 is connected in a rotationally fixed manner to the shaft 3, whose rotor toothing 6 engages in a stator toothing 7.
  • the total is approximately frustoconical Inlet area 2 arranged above the inlet of the homogenizer.
  • the clear cross section of this Inlet area 2 widens from the connecting flange 3 to the mixing tank towards the inlet of the homogenizer 1.
  • a conveying element designed as a pump propeller 8 arranged for the mix, the pump blades are on the rotor hub 4 arranged.
  • This conveyor element 8 is the second current limiter in the Meaning of the invention, since it depends on the inflow into the homogenizer the speed and the viscosity of the mix to a certain level sets and thus also limited.
  • An extension of the shaft 3 of the homogenizer 1 indicated at 9 carries a further conveyor element 10, the current limiter according to the invention to control the inflow of flowable substances or the mix forms in the inlet area 2.
  • the inlet area 2 laterally has an attached feed line 11 for other substances such as in particular powders, granules or the like on.
  • a powder valve 12 can this feed line 11 directly on the Seal the mouth in the inlet area 2.
  • In the open state of the Powder valve 12 can be the substance to be supplied with the Connection piece 13 connected storage container, not shown, in the Flow inlet area 2.
  • the device according to the invention is for mounting with the flange 3 on the Bottom of a mixing container provided. After the at least partial filling of the mixing container, the homogenizer 1 is switched on. The too Homogenizing substances are from the current limiter 10 in the inlet area 2 funded. The second current limiter 8 leads them to the homogenizer 1 to where these substances or the mix through the interaction of Rotor teeth 6 and stator teeth 7 dispersed in a known manner become. The homogenized mix leaves the homogenizer 1 through the homogenizer drain and the drain pipe 14, it is known in Way returned to the mixing container.
  • the suction power of the current limiter 8 is higher than that of the second Current limiter 10.
  • a pressure is therefore established in the inlet area 2, by the ratio of the suction power of these two flow limiters 8, 10 and the properties of the mix (in particular its viscosity) is determined and is below the internal pressure of the mixing container. Prefers it is below atmospheric pressure.
  • the powder valve 12 can be opened and substances to be mixed are via the connection 13 and the feed line 11 in the inlet area 2 led.
  • the pressure in the inlet area 2 is below the Pressure in the supply line 11. If it is below atmospheric pressure lies, can at the connecting piece 13, for example.
  • the powder valve 12 Unless powder is added continuously, but only in batches the powder valve 12 must be in during the homogenizer operation be opened and closed at certain intervals.
  • This powder and air flow prevents mixing material from striking back into the feed line 11 also during the closing process, so that there is in the closed state of the valve 12 can not form dead zones in which mix glued or clumped with powder.
