Definitions

  • the invention relates to a device for homogenizing and / or dispersing a flowable material, which is intended in particular for the production of viscous and semi-solid products, such as ointments, pastes, gels or doughs in the field of pharmacy, chemistry, cosmetics or the food industry is.
  • a device for homogenizing and / or dispersing a flowable material with a container in the bottom area of which a homogenizing and dispersing device is provided with a rotor / stator arrangement, each having through openings through which the Rotor suctioned material is driven outwards and exits radially outside of the stator in a product space enclosed by a housing.
  • a shut-off device or a closing device for an outlet opening for the material in the area of the container bottom radially outside the stator is provided, which covers a covering the outlet opening Has plate and a lifting and lowering device for the plate.
  • the lifting and lowering device for the plate is sealed through the bottom of the container.
  • a homogenizer for the production of flowable products is known, for example, from EP 0 290 033, in which a plate is arranged in the center of the container base and has an access opening for the rotor / stator arrangement located underneath. Between the rim of the plate and the bottom of the container there is always an annular gap with a small cross section, which acts as a throttle opening. Since this annular gap cannot be closed even when the flow is mixed and homogenized, the pumping capacity is reduced by leakage losses. Since the annular gap must have a small cross section, highly viscous products cannot be conveyed back into the container near its bottom via this annular gap.
  • This annular gap also presents difficulties when cleaning the device, and there are also difficulties with regard to cleaning a shut-off device in the region of a product outlet downstream and radially outside the rotor / stator arrangement.
  • This shut-off device is used to switch over for continuous operation and internal circulation operation.
  • a device for homogenizing and / or dispersing a flowable material (DE-GM 84 28 385.8), in which the homogenizing and dispersing device is arranged in the center of the container bottom and can be raised and lowered.
  • the homogenizing and dispersing device When the homogenizing and dispersing device is raised, an internal circulation can be realized and when the homogenizing and dispersing device is lowered, continuous operation can be achieved.
  • the entire homogenizing and dispersing device must be equipped with the appropriate additional aids are raised and lowered, which is extremely expensive to construct.
  • the invention aims to provide a device for homogenizing and / or dispersing a flowable material while overcoming the previously described difficulties and in particular overcoming sealing problems and possible contamination risks, which device provides a switch from internal circulation mixing or - in a structurally simple and operationally reliable manner. Homogenization and flow mixing and homogenization in the most energy-efficient manner possible and residue-free automatic cleaning of the entire device is made possible.
  • a device for homogenizing and / or dispersing a flowable material with a container in the bottom area of which a homogenizing and dispersing device is provided with a rotor / stator arrangement, each of which has through-openings through which the air sucked in by the rotor Is well driven outwards and exits radially outside of the stator in a product space enclosed by a housing, a shut-off device in the open position an internal circulation mixing or homogenization with return of the goods into the container near its bottom and in the closed position a flow mixing and Homogenization, if necessary, by pumping (external Circulation) allowed.
  • shut-off device comprises a disc which is rotatably mounted centrally on the stator and which has recesses on the outer peripheral edge which are aligned with peripheral recesses on the stator in the open position and are closed by turning the disc in the closed position.
  • the peripheral recesses of the disk and / or the stator are preferably arranged regularly.
  • shut-off device Thanks to the design of the shut-off device according to the invention, a switchover from continuous operation, that is to say with flow mixing and homogenization, and internal circulation operation, that is, circulation mixing or homogenization without the implementation of mechanical force transmission elements by the device for homogenizing and / or dispersing or the container is possible , so that sealing problems can be avoided more effectively.
  • the actuation of the shut-off device for switching is also free of any risk of contamination which may be caused thereby. Therefore, the device according to the invention can also be reliably cleaned completely and automatically without residues. Furthermore, material deposits and crust formation can be avoided, since all parts of the homogenizing and dispersing device are constantly and adequately washed by the material.
  • this changeover process is also realized in conjunction with extremely low auxiliary energy thanks to the shut-off device according to the invention. Since the recesses on the outer peripheral edge of the disk of the shut-off device are assigned corresponding to the circumferential recesses on the stator, a slight twisting movement of the disk rotatably mounted centrally on the stator is sufficient to either bring the shut-off device into the closed position, in which the recesses are closed, or into an open position to bring in which the assigned recesses are aligned, so that an internal circulation operation with return conveying into the container can be realized.
  • shut-off device Since no good can pass through in the closed position of the shut-off device, Avoid leakage losses during continuous operation, and the pumping capacity is available without restriction for continuous operation. Furthermore, the shut-off device can be reliably cleaned in the open position without difficulty, and thanks to the design of the shut-off device according to the invention there is also no risk of deposits in its effective area.
  • the shut-off device is arranged in the vicinity of the bottom of the container. This enables the product flow to be reliably shut off as close as possible to the point of exit to the container during continuous operation.
  • the rotatable disk has, preferably regularly, arranged webs which protrude into the product space adjoining the outlet from the rotor / stator arrangement and by means of which the shut-off device can be brought into its open and closed position and in each case can be held there is. It is thus possible to actuate the shut-off device in a hydrodynamic manner, since the material flow exiting the stator with a certain angular momentum hits the webs attached to the circumference of the rotatable disk. As a result, the shut-off device is held reliably in its respective open position or closed position.
  • permanent magnets are attached to the webs, which cooperate with a ring of permanent magnets arranged outside the housing in such a way that opposing permanent magnets attract each other and thereby impart a torque to the disk without contact.
  • the product flow is returned into the container tangentially to the container bottom by means of a deflection device.
  • the product stream returned to the container during the internal circulation operation can be separated from the intake stream of the homogenizing and dispersing device, which is directed centrally in the bottom region of the container.
  • Short-circuit flows between the product flow returned to the interior of the container and the suction area of the homogenizing and dispersing device can be avoided.
  • this deflection device also allows the angular momentum imparted to the product stream by the rotor of the rotor / stator arrangement to be reduced before the product stream is returned to the container during the internal circulation operation. In this way, unfavorable rotational flows of the material flow inside the container can be avoided.
  • a feed device for additives such as powder, in particular a powder suction device can be integrated into the homogenizing and dispersing device.
  • an intake pipe which opens into the intake area of the homogenizing and dispersing device and penetrates the stator, is provided for the supply of liquids, powder or the like, which, in order to avoid deposits in the supply area, has a defined leakage gap between the pressure side and the suction side of the Homogenizing and dispersing device.
  • FIGS. 1 and 2 A first preferred embodiment of a device for homogenizing and / or dispersing a flowable material, generally designated 1, is explained with reference to FIGS. 1 and 2.
  • This comprises a schematically indicated container 2, in the bottom region 3 of which a homogenizing and dispersing device, generally designated 4, is arranged, preferably below the bottom region 3 of the container 2.
  • the homogenizing and dispersing device 4 comprises a rotor 5 which is fixedly connected to a shaft 6 which is driven by a motor (not shown in more detail) which is preferably provided further down in the illustration in FIG.
  • the rotor 5 forms several passage openings for the flowable material which are distributed in the circumferential direction and are not shown in detail.
  • the homogenizing and dispersing device 4 comprises a stator 7, which is provided in a stationary manner on the container 2 in the bottom region 3.
  • the stator 7 also has through openings (not shown) for the flowable material.
  • the flowable material as illustrated by an arrow A in FIG. 1, is drawn in from above in the central area of the homogenizing and dispersing device 4 in the suction area via the stator 7 and is then homogenized by the arrangement comprising the rotor 5 and the stator 7 - And dispersing device 4 and the passage openings present there are driven radially outward to the pressure region 9 in a product space 10, which from a housing 11th is enclosed.
  • a passage gap 12 (see left-hand side in FIG.
  • the stator 7 is formed between the stator 7 and the bottom region 3 of the container 2, which has a deflection device 13, which in the example shown is formed on the stator 7, through which the internal passage gap 12 is open when the passage gap 12 is open Circulation operation of the product stream tangential to the bottom region 3 of the container 2 is conveyed back into the same after passing through the homogenizing and dispersing device 4.
  • This passage gap 12 is assigned a shut-off device 14, which comprises a disc 15 which is rotatably mounted centrally on the stator 7.
  • the disk 15 preferably has regularly arranged recesses 16 on the circumferential edge, and circumferential recesses, which are preferably not regularly shown, are also provided on the circumferential edge of the stator 7.
  • the recesses 16 of the disc 15 are aligned with the associated recesses on the circumferential edge of the stator 7, so that the passage gap 12 is released, and the flow of material after passing through the homogenizing and dispersing device 4 and out of the product space 10 at the pressure area 9 via the aligned recesses 16 and via the deflection device 13 tangential to the bottom area 3 of the container 2 and the passage gap 12 to the container in order to realize an internal circulation operation.
  • the rotatable disk 15 has webs 17 on the circumference, preferably arranged regularly, and projecting into the product space 10.
  • the shut-off device 15 illustrated in FIG. 1 it comes from the homogenizing and dispersing device 4 emerging product stream with a certain angular momentum on the webs 17, so that depending on the direction of rotation of the rotor 5 by means of the action of the webs 17 by the product stream, the disk 15 is reliably held in the open position shown, for example, in FIG.
  • the product stream emerging from the homogenizing and dispersing device 4 causes the webs 17 are applied in such a way that the disc 15 is rotated slightly so that the recesses 16 of the disc 15 and the recesses on the stator 7 are no longer in alignment and the shut-off device 14 assumes its closed position.
  • a continuous operation if necessary with external circulation, is then carried out, in which the material flow leaves the device via an outlet 18 and is conveyed, for example, to a collecting container (not shown), or in turn by means of a pumping line at a greater height into container 2 is initiated in the event of external revolution.
  • the disc 15 is also held reliably by the product stream that strikes the webs 17.
  • the shut-off device 14 is thus adjusted into its open position and into its closed position in a hydrodynamic manner.
  • a device for additionally introducing an additive for example in the form of a powder suction 21, is shown at 20 in FIG.
  • the feed line takes place in the suction area 8 of the homogenizing and dispersing device 4.
  • This device 20 for the additional introduction of an additive, such as powder or the like includes, among other things, an suction pipe 22 integrated in the homogenizing and dispersing device 4.
  • the suction pipe 22 passes through the stator 7 in an area above the rotor 5 and is sealed there. This suction pipe 22 opens into the suction area 8 of the homogenizing and dispersing device 4.
  • This suction pipe 22 has a leakage gap 23 between the suction area 8 and the pressure area 9, formed by the product space 10 and the homogenizing and dispersing device 4.
  • This defined leakage gap 23 maintain a targeted leakage flow between the pressure area 9 and the suction area 8 of the homogenizing and dispersing device 4 in order to keep the device 20 free from deposits for the additional introduction of an additive, when a suction valve of this device 20 is closed. This avoids contamination when an additive is added by means of suction.

  • the assignment of the permanent magnets 30 and the permanent magnets 32 is made in such a way that the poles of opposing permanent magnets 30, 32 attract each other. If the ring 31 arranged outside the housing 11 is now rotated, the permanent magnets 30 run on the webs 17 'due to the attraction movement and impart a torque to the rotatable disk 15.
  • the disk 15 can be brought into the open or closed position of the shut-off device 14 in a contactless manner by rotating the ring 31.

  • shut-off device 14 is obtained by means of a fixed plate and a plate or disk 15 that can be rotated for this purpose at the outlet area for returning in the area of the bottom 3 of the container 2, which shut off a passage gap for the changeover from continuous operation to internal circulation operation or can release.
  • the switchover is carried out in the most energy-saving manner possible with a short switching travel, for example by only slightly rotating the rotatable disk with respect to a fixed plate or a corresponding design of the stator 7. Since the passage gaps 12 of this shut-off device 14 are reliably closed during continuous operation, pumping over may be necessary can be effectively implemented in external continuous operation without leakage losses. As a result, the efficiency of pumping devices that may be provided can be improved. In particular, however, such a device 1, 1 'allows processing to be carried out reproducibly and contamination to be effectively avoided. In addition, the entire device 1, 1 'can also be automatically and reliably cleaned, which is particularly important in the field of pharmacy, cosmetics, chemistry and the food industry because of the sterility.
