Definitions

  • the invention relates to a system for mixing a predetermined amount of liquid with a predetermined amount of powdered solid.
  • a device for wetting and dispersing powdery solid in liquids which has a disk-shaped rotor in a dispersion chamber. On one side of the disc-shaped rotor is an inlet for the powdery solid and the inlet for the liquid is provided on the other side of the disk-shaped rotor.
  • the pulverulent solid is brought together with the liquid in a wetting space in the outer edge region of the rotor disk.
  • An outlet for the liquid-powder mixture is located on the outer edge of the wetting chamber surrounding the rotor disk.
  • the liquid and the powdery solid are supplied by suction using the high-speed rotor disc.
  • the powdery solid can be from a funnel arranged above the device and / or by means of a hose from a bag, storage container or the like. be sucked in. From the magazine S ⁇ FW Journal Cosmetics Detergents Specialties, April 2, 1992, pages 2 to 4, it has also become known for this known device to connect the outlet of the device to the liquid storage container so that the liquid is circulated through the device is and the solid is thereby concentrated in the liquid. The announcement of the powdery solid is relatively difficult and depends on numerous influencing variables, for example the flow behavior of the powdery solid.
  • the invention is therefore based on the object of creating a system of the generic type which can be operated in such a way that dusting on the one hand and pronounced agglomerate formations on the other hand are largely avoided.
  • the system shown in the drawing has a storage container 1 which has a volume sufficient to hold a predetermined amount of liquid 2.
  • An agitator 3 which can be driven by a drive (not shown) is arranged in the storage container 1.
  • a screw mixer 4 is provided, the essentially cylindrical housing 5 of which is surrounded by a temperature jacket 6 with an inlet 7 and an outlet 8 for a temperature medium for heating or cooling.
  • a mixing shaft 9 is arranged in the housing 5 and can be driven by a mixing drive motor 11 via an upstream transmission 10.
  • a feed pipe 13 opens into its interior 12.
  • the mixing shaft 9 is designed as a worm shaft with a helical screw shaft 14 running around it.
  • the housing 5 can also be provided with a so-called clearing wheel which meshes with the screw webs 14 in order to ensure proper transport of the materials to be mixed through the interior 12 in the conveying direction 15.
  • clearing wheels are known for example from DE 24 32 860 C2 (corresponding to US Pat. No. 3,957,210).
  • the screw-mixing machine 4 can also be designed as a double-screw machine, which is of a type that is forcibly conveying.
  • An intensive mixing section 17 adjoins the screw section 16 of the mixing shaft 9 which is provided with a screw web 14 and in which the mixing shaft 9 is occupied with short peg-like or strip-like mixing tools 18 which are assigned counter tools 20 attached to the inner wall 19 of the housing 5 .
  • the mixing tools 18 and the counter tools 20 are each arranged on alternating circles around the central axis 21 of the mixing shaft 9. The smaller the distance of the mixing tools 18 from counter tools 20 adjacent in the direction of the central axis 21, the greater the dispersing effect.
  • a return conveyor 22 is provided, which comprises a pump conveying wheel 23 attached to the end of the mixing shaft 9, which conveys the liquid 2 into an outlet channel 24 opening out tangentially from the housing 5.
  • the outlet channel 24 is connected to the reservoir 1 via a return line 25. If the mixing machine 4 is arranged directly above the storage container 1, then naturally no return conveyor must be provided.
  • the feed connector 13 consists of a lower funnel-shaped section 26 which is flanged to the housing 5 and opens into the interior 12 and which widens upwards, and an upper, approximately cylindrical section 27.
  • a solid material projects into the upper cylindrical section 27 of the feed connector 13.
  • Feed pipe 28 concentrically into which free-flowing, powdery solids are introduced from at least one solids metering device 29. These solids emerge from a lower outlet opening 30 of the feed pipe 28 into the funnel-shaped section 26 of the feed connector 13.
  • a ring line 31, which surrounds the cylindrical section 27 of the feed connector 13 and is provided somewhat above this lower outlet opening 30, is provided by an approximately C-shaped jacket in cross section 32 is formed with a ring shape.
  • the way bounded annular space 33 of the ring line 31 is connected to a liquid supply line 34 which leads to the reservoir 1.
  • At least one liquid passage opening 35 is formed in the wall of the cylindrical section 27 of the feed connector 13, for example in the form of an adjustable gap.
  • a pump 36 flows from the storage container 1 through the feed line 34 and through the through openings 35 into the cylindrical section 27 of the feed connector 13. It runs down the inner wall 37 of the cylindrical section 27 into the funnel-shaped section 26
  • the downward flowing solid 38 is completely enveloped by the liquid 2 running off on the inner wall 37.
  • the liquid 2 is fed to the mixing machine 4 in the feed nozzle 13 under gravity. It also serves as a transport medium for the solid 38, which is also fed under the force of gravity.
  • the solids metering device 29 has a funnel 40 which either has a volume which is sufficient to hold the entire batch of solids 38 or to which the predetermined amount of solids is continuously fed during a complete mixing cycle.
  • the dosing accuracy of the solids dosing device 29 is not particularly demanding.
  • the metering device only has to be adjustable in such a way that it inputs the predetermined amount of powdered solid over a predetermined period of time into the feed nozzle 13.
  • the metering device 29 can have a volumetrically conveying screw or a gravimetrically conveying screw or a gravimetrically conveying belt conveyor. In the simplest and sufficient version, a volumetrically conveying screw is provided.
  • Such metering devices are known and commercially available. In principle, it is also sufficient if a setpoint for the solid volume to be dispensed per unit of time can be set.
  • a fill level measuring device is arranged in the funnel-shaped section 26 of the feed nozzle 13, which has a fill level probe 41 that operates without contact.
  • This probe 41 continuously sends fill level signals to an input 42 of a control device 43.
  • These signals are processed in the control device 43 in such a way that a control signal corresponding to a minimum fill level 44 and a maximum fill level 45 is generated which is output via outputs 46, 47 for alternative or cumulative control the drive motor 11 of the mixing shaft 9 and / or a pump drive motor 48 is supplied.
  • the probe 41 reports that the minimum fill level 44 has been undershot, then either the speed of the mixing shaft 9 and thus the throughput of the mixing machine 4 is reduced by driving the drive motor 11 or the speed of the drive motor 48 of the pump 36 and thus its delivery rate is increased. If, on the other hand, the probe 41 reports that the maximum fill level 45 in the feed connector 13 has been exceeded, then either the speed of the drive motor 11 and thus the throughput of the mixing machine 4 is increased or the speed of the drive motor 48 of the pump 36 and thus the liquid supply are reduced. Both measures can also be taken simultaneously.
  • V Blender V Solid + V mixture .
  • a complete filling of the mixing machine 4 can be achieved in that a back pressure is exerted on the mixing machine 4 via the return line 25.
  • an adjustable throttle 51 with an associated manometer 52 is provided in the return line 25.
  • the throttle 51 is connected to an output 53 of the control device 43.
  • the throttle 51 is controlled at a predetermined high relining of the mixing machine 4 so that the minimum fill level 44 is not fallen below and the maximum fill level 45 is not exceeded, the pressure gauge 52 being used to monitor that a maximum permissible pressure in the System is not exceeded.
  • the setting is such that when the liquid 2 in the storage container 1 is completely circulated through the mixing machine 4 and back to the storage container 1, only a fraction of the solid 38 to be added to the liquid 2 is added.
  • two to ten circulations of the liquid 2 may be appropriate until the solids 38 have been completely added. If a fineness of dispersion of the mixture is desired, then in many cases more than ten cycles are required.
  • the term liquid also includes the mixture of liquid 2 and solids 38 formed during the circulation. A pure liquid 2 is only present at the beginning of the process. As described, this is mixed with solids 38 and thus forms a flowable liquid-solid mixture, which for the sake of simplicity is also referred to as liquid.
  • the agitator 3 in the reservoir 1 serves to bring about a concentration compensation in the reservoir 1, that is to say to ensure a uniform concentration of solid 38 in liquid 2 in the entire reservoir 1.
  • An eccentric screw pump or a conventional mixer provided with conveying devices can also be used as the mixing machine 4. It is essential that it has its own funding, that is, it gives the liquid 2 and the solid 38 a delivery pulse.
  • the storage container 1 ' is provided with an intensive agitator 3', which causes an intensive circulation of the liquid 2 in the storage container 1 '.
  • intensive agitators 3 ' are known; These are, for example, so-called spiral agitators, which in particular also exert a pronounced pull-in effect on the surface of the liquid 2 on the latter.
  • the storage container 1 ' is provided with a lid 54 in which a vent opening 55 is provided, for example for a pendulum vent.
  • the feed nozzle 13 in the embodiment described in FIG. 1 is mounted in the lid 54 and ends above the liquid 2. It is arranged so far above the liquid 2 that even after the entire solid 38 has been completely mixed into the liquid 2, it does not Mixture immersed.
  • An operating device 56 is also provided, by means of which the delivery rate of the pump 36 can be adjusted on the one hand by correspondingly adjusting the speed of the pump drive motor 48 and on the other hand the metering rate of the metering device 29.
  • the delivery rate of the pump 36 can be adjusted on the one hand by correspondingly adjusting the speed of the pump drive motor 48 and on the other hand the metering rate of the metering device 29.
  • an agitator drive motor 57 has the function of a mixed drive motor which drives the agitator shaft 59 of the agitator 3 'serving as a mixing shaft by means of a V-belt drive 58.
  • the storage container 1 'with agitator 3' thus serves not only as a storage container, but also as a mixing device.
