Definitions

  • the invention relates to a device for mixing and homogenizing flowable products, in particular for the pharmaceutical, cosmetic and food industry, with a vacuum container which can be closed by a lid, a homogenizing device arranged at the bottom thereof and a mixing or stirring device arranged on the lid.
  • a device of this type is known from DE-A-15 07 528.
  • an agitator with agitating arms which protrude close to the container wall is driven by a drive motor hanging under the container bottom and a mixing mechanism led down from the lid is driven by a motor which has just been arranged.
  • the toothed colloid mill used as a homogenizer is arranged eccentrically hanging on the bottom of the container and conveys the material through a circulation line for degassing to a centrifugal plate arranged under the lid, which Spreads well by centrifugal force and then hurls it through a ring sieve. In this way, in addition to the treatment processes already mentioned, emulsification, dispersion and wetting can also be carried out in the same device.
  • a device for mixing and / or degassing highly viscous media under vacuum is known from DE-PS 24 45 287, with an equally shaped tube revolving in a conical or cylindrical vacuum container, on the outside of which a conveyor spiral is formed.
  • the processed mass between the inner wall of the container and the outer surface of the circumferential tube is conveyed upwards by means of a drag flow to an overflow, from where it flows back into the material level.
  • the main aim here is to degas the highly viscous material as completely as possible and that the rotor should be able to be driven at a variable speed. A low speed is sufficient for this, which is also preferred there.
  • the rotor can hardly be operated at high speeds, since the entire upward conveyance is brought about by the screw spiral, which can easily lead to overheating and therefore to an undesirable change in the quality of the material.
  • a device for accelerating the uniform mixture of powder and liquid is known from Japanese Patent Application Laid-Open No. 57-127431 (A), the defoaming being achieved first of all by combining a vacuum mixer for liquid and powder uses fluid with a device for comminuting the powder in the rotating mixture.
  • a constant amount of liquid is placed in a vacuum container, then a high-speed drive and a slow-speed drive are started in order to supply a constant amount of powder and then to seal the container.
  • a standing screw pump with stirring blades rotates and mixes the liquid as it runs over the top surface of an umbrella-shaped plate, with two or more cone-shaped rollers running on their axes along the surface of the plate and with a device being provided that the aggregates of undispersed and dispersed powder repeatedly crushed in the mixed liquid and subjected to vacuum for a predetermined time.
  • This device accelerates the uniform mixing of the liquid, whereby foaming occurs.
  • the screw conveyor used there does not allow fine particles to be dispersed in a liquid phase due to the very low impact of shear forces, which is why the object of the invention is a homogenizer which, in contrast to the screw conveyor design, generates significantly higher shear forces and thus also disperses fine particles in a liquid phase enables.
  • an optimal degree of deaeration is only achieved when the product is exposed to the vacuum as a film for a certain time.
  • This film formation is achieved in the subject matter of the invention by the guide cone, since the dispersed suspension is spread out into a thin film on the inside of the cone by the centrifugal force that occurs, which layer is increasingly thin in layers runs steeper, so that even the finest air bubble is exposed and burst.
  • the device according to the Japanese laid-open patent lacks the preferred function of two-stage processing of the product, as is achieved in the subject of the application by alternating right and left rotation of the central shaft.
  • Both versions have in common that they enable rapid mixing of powder in a similar manner by mixing propellers with high throughput.
  • the mixing propeller transports the product transversely downward, so that inevitable dispersion must take place via the high-shear tooth colloid mill.
  • the possibility of reversible treatment of dispersions on units of less than 10 m ⁇ particle size and the removal of microbubbles from a suspension in a very short time is eliminated by the possibility of optimal film distribution on the inside of the guide cone.
  • the invention is based on the device defined at the outset for mixing and homogenizing flowable products and pursues the task of changing the known mixing and homogenizing device in the simplest possible manner in such a way that the material is uniform, if possible without stopping Experienced stress.
  • the device according to the invention is characterized in that the homogenizing device is arranged with such a vertical suction distance above the bottom of the container, that the flowable product can be sucked off for carrying out a treatment, and that in the lower part of the vacuum container a Homogonisierein signedde rotating hollow guide cone is provided, which widens upwards and forms a flow ring gap with the container wall.
  • the homogenizing device can suck the material directly to the side of the container bottom and convey it into the guide cone, which widens upwards.
  • the material is conveyed upwards / outwards along the conically widened inner surface of the guide cone up to its upper edge into the flow ring gap which it forms with the container wall.
  • the material spreads evenly with constant thinning of the layer and flows in a thin ring stream from the top of the cone to the bottom of the container.
  • the vacuum container is constantly on during processing remains connected to a vacuum pump, the gas content of the goods is reduced from circulation to circulation.
  • This proportion like the degree of homogenization or the other desired properties of the good, can be measured automatically and, if necessary, the process can be terminated if minimum qualifications are met with regard to a series of predetermined measured values.
  • Narrow flow cross sections result at most in the homogenizing device acting as a circulation pump. There is therefore no risk of any constipation, overuse or change in the quality of the goods, which can relax very largely and evenly.
  • the guide cone itself contributes to the homogenization through the thin-layer flow on its surface and also to the dispersion caused by the force of gravity of the goods. It also takes on a limited function for the mixture of the good components.
  • the homogenizing and mixing or stirring device are driven by two drive shafts arranged centrally in the container axis, the inner drive shaft being at least connected to the homogenizing device, while the outer drive shaft is connected to a cage-like stirring basket.
  • the drives are expediently arranged on the container lid. The latter enables better overview and sealing as well as easier maintenance. The assignment of the various aggregates is also simplified.
  • the guide cone can thus be connected to the rotor of the homogenizing device, for example by being attached to the inner drive shaft by a spoke star.
  • the surface of the guide cone can have a precisely geometrically smooth surface, but can also be structured, preferably in the circumferential direction, in particular at the same spacing be radially changed, such as wavy, tapered or arched out of the surface line.
  • the stator of the homogenizing device can be attached to the arms of the mixing basket that are clinging to the container wall.
  • the direction of rotation and the speed of rotation of the homogenizing device are therefore predetermined by the difference or sum of the speeds of the two drive shafts. This favors the use of a toothed colloid mill which is set up for reversing operation and which, owing to its low weight and small dimensions, can be reliably held and guided even at higher speeds without impairing its fine grinding and emulsifying function.
  • the circulation capacity of the homogenizing device or the toothed colloid mill can be significantly increased if, according to a further development of the invention, the mill rotor has or forms an axial screw wheel, in particular for its attachment to the inner shaft, with conveyor blades separated from one another by spacing sectors in an annular conveyor channel.
  • the mill rotor has or forms an axial screw wheel, in particular for its attachment to the inner shaft, with conveyor blades separated from one another by spacing sectors in an annular conveyor channel.
  • throttle or shut off the internal flow can be accomplished by a cover element arranged on the axial paddle wheel, which can be pivoted between stops around the circumferential angle of a spacing sector. This can be done arbitrarily, but is preferably carried out automatically by the pumping medium remaining with respect to the rotor, in particular when the rotor reverses in speed.
  • a vortex breaker can project cantilevered from above approximately axially at a radial distance from the container axis into the guide cone. This arm attached to the slow-moving agitator basket counteracts above all the turbulence resulting from the fast-running homogenizing device.
  • the homogenizer and agitator are preferably connected to different drive motors, of which at least one is reversible and at least one, in particular both, is or is speed-controllable. In this way, practically all deviations from the preprogrammed processing result can be corrected.
  • At least one, in particular both, drive motors is or are expediently connected to a control for automatically controlling the drives according to predetermined or automatically detectable operating data of the device and / or the processed goods.
  • a control computer of the device is preferably assigned a comparison computer which determines control values from all the specifications and functional values supplied to it and prepares them for transmission to the drive motor or motors.
  • (1) denotes a vacuum container, the upper opening of which can be closed by means of flanges (2) by a cover (3).
  • This lid can be raised in a known manner, for example by one or more hydraulic cylinders or other drive motors, in order to make the interior (4) of the container accessible for cleaning purposes, for example.
  • the material to be processed can optionally be filled into a funnel (5) arranged on the lid (3). Its connection to the interior (4) is hermetically sealed by a slide (6) which can be adjusted by means of a crank or similar operating element (7).
  • the material can also be sucked in via the funnel (10) and line (11) with shut-off valve (12) through the container bottom (13) under vacuum.
  • the finished material is optionally discharged by opening an outlet valve (14) which is located centrally in the container axis (19) in the container base (13).
  • the vacuum container (1) is connected in a manner not shown to a vacuum pump. It can be provided in the lower cup-shaped container part or in the lid (3).
  • the lower part of the container has a double jacket (15) through which the heating and / or cooling medium flows.
  • the container can be fixed, movable on a carriage, tiltable about a horizontal axis or arranged on a turret body rotatable about a preferably vertical axis and the like.
  • the homogenizer can be driven by the inner shaft (20) and the stirring basket (18) by means of a tubular outer shaft (21). While the inner shaft (20) starts from the upper mixer motor (22), the outer shaft (21) is connected to the lower agitator motor (23) and is mounted in a bearing tube (8) that is flanged onto the cover (3). Both shafts are hermetically sealed through the cover (3) through ring seals (24, 25). Compared to an arrangement of the motors (22, 23) below the tank bottom (13), this facilitates the rotating leadthrough and sealing.
  • Both motors (22, 23) and their shafts (20) and (21) can be driven according to the arrows (28) and (29) in both directions of rotation with variable speed, preferably using frequency converters.
  • the stator (30) of the toothed colloid mill (17) is held firmly on the stirring basket (18), while the rotor (31) is connected to the inner shaft (20).
  • the effective rotational speed of the tooth colloid mill thus corresponds to the vectorial difference in the rotational speeds of the shafts (20) and (21). You expediently run in opposite directions.
  • a guide cone (34) sits on the inner shaft (20) by means of a sleeve (32) and spoke arms (33) just above the toothed colloid mill, which cone extends the shape of e.g. from the top of the toothed colloid mill to the middle of the container. has a smooth truncated cone with a tip angle of about 60 ° and comes close to the inner surfaces of the mixing bowl (18). While the outer shaft (21) with the mixing bowl has a speed in the range of 20-100 U / min, the inner shaft (20) runs at a rotation speed of approx. 500-3000 U / min. Since all parts rotate around the shaft of the axis (19), a pronounced central vortex is usually established.
  • a vortex breaker (35) is led down from the stirring basket (18) at a radial distance and parallel to the container axis (19) into the guide cone (34). In this way, the local axis of rotation is shifted out of the container axis (19) with constant change, which brings a further mixing effect.
  • the spoke arms (33), like the vortex breaker (35) and the other rods (26) of the stirring basket (18), are designed as cylindrical tubes, but can also have other suitable shapes.
  • the stirring basket (18) also has a plurality of scraper blades (37) on the inner wall (36) of the vacuum container (1) and scrapers (47) or the like on the outer wall surface of the guide cone.
  • an axial paddle wheel (46) with an inner ring (54) and an outer ring (55) is used to fasten the rotor (31) of the toothed colloid mill (17), which is arranged in an annular manner by means of star-shaped conveying blades (49) Delivery channel (50) are connected.
  • Delivery channel (50) Delivery channel (50) are connected.
  • a strong rotational flow is built up centrally to the container axis (19) in the guide cone (34), which serves primarily for mixing, while the smaller quantity of material passed through the pump teeth (56) between the stator and rotor is primarily exposed to the homogenization.
  • the material flows mix again and again, so that approximately the same quality of the material can always be achieved in the entire vacuum container.
  • a cover member (51) in the form of a cover disk is therefore mounted above the delivery channel (50) in the paddle wheel (46).
  • This covering element has three sector wings (57) which form spacing sectors (58) of equal size between them, each with a tip angle of 60 °.
  • the conveyor blades (49) have the same sector area, so that the paddle wheel (46) as well as the cover member (51) have the approximate shape of a Maltese cross Has. In the open position in FIG.
  • the conveying blades (49) are therefore covered by the sector blades (57) in their position (57) from FIG. 5, so that conveying can be carried out through the spacing sectors (58).
  • the sectors of the same size join together. This can be designed as required so that the flow is completely or partially blocked.
  • a triangular cross section is provided for the conveyor blades (49) according to FIG. 5, but this is unfavorable for flow, especially if the end face is at the front in the circumferential direction.
  • a triangular extension (49 ') can be connected to this end face in the opposite position.
  • this cross section can be obtained entirely if a central shutter, as is known in photographic cameras, or a shutter in the manner of a photographic aperture is used.
  • the conveying channel (50) can be fully opened, for example when the diaphragm is open.
  • the slats are held firmly on the outer stops by centrifugal force.
  • the slats In the closed position of the cover or the lock, the slats must be pressed inwards against the effects of centrifugal force. They are then subjected to greater vibration, so that here the shafts (21, 22) should run in the same direction in order to achieve the lower effective speed of the mill rotor.
  • Part of the goods can also be taken continuously or intermittently as a sample and checked for its nature, such as viscosity, grain size, temperature and the like.
  • Detectors can also be embedded in the rotatably held container (1).
