Definitions
- the present invention relates to a device for metering and / or mixing highly viscous and non-flowable materials, in particular pigment pastes.
- the device is used in continuously operating and closed systems, in particular for dosing the highly viscous and non-flowable materials in an extruder.
- the material addition in a continuously working and closed system can e.g. by means of a Buhler pump SRB-83076, whereby the paste-like mass must be pressed into the pump from a funnel, since it is only poorly sucked in by the pump itself. This can be done by a slide or an auger. It has been shown that sticky, non-flowing pastes stick the funnel and feed elements (feed screws, slider). The glued paste can only be detached from the elements by stripping. According to the principle of the invention, all parts in contact with the product should strip each other and at the same time press the material into the pump. In the case of pastes that only get a pumpable consistency through shear, such as pigment press cakes, the material should be sheared by the stripping elements.
- German Patent Application No. 1 180 321 discloses a silo with a discharge device which has a rotatable bottom surface with driver strips, so that a considerable part of the fuel supply in the silo is rotated.
- a screw which is arranged directly above the support surface and which conveys the material radially from the center of the base to a conveying line system arranged outside the silo, is used as the discharge device.
- German patent application DE 3304026 A1 discloses a silo with a discharge device which has a screw which moves in such a way that the silo material is moved towards a feeder. When used as a distribution device, the screw is driven in the opposite direction.
- a further screw conveyor is arranged at the upper end of a conveyor shaft, which can be pivoted vertically relative to the conveyor shaft and rotated therein.
- the object of the present invention is to provide a constant dosage of highly viscous and non-flowable materials, such as.
- pigment concentrates pigment press cakes, offset pastes, offset concentrates, flush pastes
- aerosil pastes steel engraving colors
- all types of putty gel pastes, gelled binders, etc.
- the disadvantages listed above are to be avoided.
- the object of the invention is achieved with the features of claim 1.
- the invention is based on the above-mentioned funnel, which is used as a metering device, as the closest prior art.
- the task is solved in that a double screw is arranged within the funnel and the funnel rotates about its own vertical axis.
- the worm replaces the slides or scrapers currently used, which are usually located on the inner wall of the funnel.
- the snails brush each other and the funnel wall constantly.
- the product is repeatedly stripped from the entire funnel wall by the rotating movement of the funnel.
- the distance between the inner wall of the funnel and the twin screw is in the range 0-3 cm.
- twin screw it is expedient for the twin screw to extend along the hopper wall into a product outlet opening at the lower end of the hopper.
- the screws of the twin screw are driven in the same direction or in opposite directions.
- twin screw is driven in the same or opposite direction with respect to the hopper.
- the delivery capacity of the twin screws is higher than the delivery capacity of the pump.
- the rotational frequencies of the screw are in the range of 20-100 rpm and the funnel in the range of 1-5 / min.
- Fig. 1 schematically in side view of a funnel with the twin screw
- Fig. 2 is a plan view of the funnel with the directions of rotation of both moving parts.
- the materials enter a hopper 2, for example from containers or by means of suitable transport devices, neither of which can be seen.
- the product is conveyed downwards in the direction of the product outlet opening 4 on the one hand to a relatively small extent by the rotating funnel 2 itself and on the other hand by the Double screw 1.
- the screw has two functions, namely stripping and conveying the product.
- the stripping of the pasty mass glued to the inner wall 6 of the funnel is brought about by the mutual rotations of the funnel 2 and the screws 1 a, 1 b. These rotations can be coordinated with one another and regulated if necessary. It has been found that the material is sheared strongly in the same direction in FIG. 2 and within a few minutes the entire material contained in the hopper 2 is mixed.
- the full-leaf and concave screws are particularly suitable for the present device.
- the Bühler pump SRB-83076 is also used.
