Definitions

  • the invention relates to a device for producing a mixture of at least one crushable lumpy solid and at least one liquid component, in particular for use in the refinement of soap, with a rotatably arranged mixing screw for conveying and mixing the mixture components, at least one feed device for feeding the liquid components into the mixing screw, and an output device connected to the mixing screw, which has at least one stationary perforated plate, via which the mixture exits the mixing screw.
  • the ingredients are often granular solids, liquids and / or emulsions.
  • the end product can be a free-flowing or viscous emulsion or a plastic mass.
  • Known devices for producing the mixing are designed with due regard to the respective mixing problem and often have a screw driven by a rotary drive and a device connected to the screw for continuing the comminution and mixing process started by the screw.
  • liquid constituents are added to the material and mixed with it intimately and homogenized.
  • the aim is to create a network-like structure with air spaces in the material.
  • the material is first pre-shredded and compacted in a first mixing screw and further shredded at the outlet end of the mixing screw in a shredding head rotating with the latter.
  • Liquid is fed via a feed head connected to the comminution head from the end of the device remote from the mixing screw into a mixing and homogenizing space and mixed and homogenized therein by means of resilient blades and then ejected via a spreading plate, a pressure plate and a cutting head into a pressurized end chamber and fed by this to a second mixing screw. This is where further homogenization and densification take place. Overall, this facility is also complicated and expensive.
  • the object of the invention is to provide a device of the type mentioned, which is simple and inexpensive, the it is also suitable for processing plastic granules, in particular soap granules, in mixtures, allows them to be mixed intimately with other constituents, for example liquids or emulsions, and produces a perfectly homogeneous end product.
  • a device for solving this problem is characterized in that the outlet opening of the feed device for the liquid constituents is arranged at the inlet end of the mixing screw in the area of the solids inlet in a known manner, and that a device for homogenizing the mixture is also provided as the output device, which at least includes a stage in which a perforated plate is preceded by a splicing tool with wings that rotates during operation.
  • the invention has the following advantages.
  • the homogenization process is continued in the subsequent homogenization stage.
  • Such a homogenization stage is extremely effective in a small space and an arbitrarily fine degree of homogenization can be achieved by stringing together several homogenization stages.
  • the simplicity of the furnishings is impressive. This saves costs and space.
  • the device is suitable for processing various plastic granules, and especially for perfuming soap.
  • This mixing screw can have fewer than four turns, preferably two turns. A ratio of 1: 1 between the diameter of the mixing screw and its length is favorable.
  • the mixing screw can be arranged vertically, with the horizontal conveying direction of a metering device upstream of it. This makes a space-saving design possible, which allows the device to be attached to a rolling mill above the rollers, the output device feeding the rollers.
  • the homogenizing effect of the mixing screw is favored if the outlet opening of the feed device feeds the liquid components into the drop section between the metering device and the mixing screw.
  • a particularly strong homogenizing effect is achieved if at least one of the wings of the calving tool has a front intake surface facing the perforated plate, which in the direction of rotation gives the product a component of movement in its flow direction during operation and presses it through the perforated plate, and one connected to the intake surface , in the direction of rotation rear calving surface, which is arranged at a short distance from the perforated plate and has a homogenizing effect on the mixture which has not passed through the perforated plate.
  • the feed surface can be a flat surface which is arranged at an acute angle to the perforated plate.
  • the calving surface is advantageously a flat surface arranged parallel to the perforated plate.
  • the wings of such a salvation tool crush the mixture into thin layers and have a homogenizing effect on them at the same time.
  • the splicing tool is preferably attached to the worm shaft so that it can be dismantled, it rotates together with it during operation and advantageously has a plurality of blades projecting outward in the radial direction.
  • Such a tool works perfectly and is easy to manufacture. It is easily accessible for cleaning purposes.
  • the splitting tool can be preceded by a remodeling tool which is arranged at a distance therefrom and rotates together with it during operation, with wings projecting outward in the radial direction.
  • the wings of such a shifting tool are preferably arranged offset in the circumferential direction from the wings of the calving tool.
  • the shifting tool is removably attached to the worm shaft and rotates with it during operation. It effects a layering of the mixture that promotes homogenization and is also easily accessible for cleaning purposes.
  • the perforated plate is preferably connected to a cutting tool which rotates during operation and has blades which project outwards in the radial direction and is connected downstream.
  • a cutting tool which rotates during operation and has blades which project outwards in the radial direction and is connected downstream.
  • This is advantageously attached to the worm shaft in a removable manner and rotates together with it during operation.
  • Such a tool may be necessary with some mixtures in order to separate the escaping product respectively. Its effect is particularly good if its wings are offset in the circumferential direction from the wings of the calving tool upstream of the perforated plate. This tool is also easily accessible for cleaning purposes.
  • the perforated plates are advantageously held detachably in the screw housing and secured against rotation.
  • the diameters of the holes of the perforated plates of successive stages preferably decrease progressively in the direction of flow. A progressive refinement of the homogenization process is thereby achieved.
  • the stratification tool and the salvage tool are arranged between two perforated plates, the stratification tool simultaneously serving as a cutting tool for the first perforated plate. Its wings are offset circumferentially from the wings of the calving tool. The product cut off from the first perforated plate is thus released between the wings of the calving tool, so that a further mixing effect takes place between the two perforated plates.
  • a locking ring which can be removed by means of a bayonet lock is advantageously arranged.
  • the entire homogenizing device is thus easy to disassemble and easily accessible for cleaning purposes when changing the mixture.
  • the system according to FIG. 1 has a metering device 1, a mixing device 2 and a rolling mill 3.
  • the metering device 1 is used to meter the amount of the granules to be fed and is fed with soap granules via a feed hopper 4. It has a worm housing 5, a worm shaft 6 rotatably mounted therein and a metering worm 7 fixedly arranged on the worm shaft 6.
  • the worm shaft 6 is driven by a first drive motor 9 via a first sprocket gear 8.
  • the mixing device 2 is connected to the metering device 1. This has a worm housing 10, a worm shaft 11 rotatably mounted therein and one on the worm shaft 11 fixedly arranged mixing screw 12.
  • a feed device 17 for the perfumed dispersion acted upon by a pump 16 opens into the mixing device 2, its outlet opening 18 being arranged at the inlet end of the mixing screw 12 in the area of the solids inlet.
  • the pump 16 is driven by the metering worm shaft 6 via a second sprocket gear 19.
  • a homogenizing device 20 described in detail below is provided as the output device. This is arranged above the rolling mill 3, which has an inlet hopper 21, three rotatably arranged rollers 22 and a scraper 23. The mixture emerging from the homogenizing device 20 falls through the inlet funnel 21 into the first nip 24 and is carried over the last two rollers 22 and the scraper 23 as piled soap.
  • the soap granulate 26 falls freely from the metering screw 7 at the input end of the mixing screw 12 into the screw chamber 25.
  • the outlet opening 18 of the feed device 17 opens into the screw chamber 25 in this area and, in free fall, adds the dispersion 27 to the loose stream of soap granules.
  • the inspection hole 45 is open to the surroundings.
  • the worm housing 10 is provided with straight or helical cables 46 which increase the friction of the inner wall.
  • a first variant of the homogenizing device 20 is shown at the outlet end of the mixing device 2. This device, shown in an exploded view in FIG.
  • the 3 has a saponification tool 28 connected to the mixing screw 12 with three in the radial direction projecting blades 29, a perforated plate 30 arranged at a small axial distance from the blades 29, and a cutting tool 31 arranged close to the perforated plate 30 with cutting blades 32 projecting in the radial direction.
  • the two tools, the ointment tool 28 and the cutting tool 31 are detachably fastened on the mixing screw shaft 11 by means of the screw nut 33 and rotate together with the mixing screw 12 during operation.
  • the wings 32 are arranged offset to the wings 31 in the circumferential direction.
  • the perforated plate 30, however, is detachably held in the worm housing 10 and secured against rotation.
  • a locking ring 34 is provided at the output end of the screw housing 10. This is detachably held in the screw housing 10 by means of a bayonet catch.
  • a part of the perforated plate 30 shown in cross section has holes 35 through which the mixture exits the mixing device 2.
  • the wings 29 of a saponification tool 28 can be seen in cross section at a short distance from the same.
  • the direction of movement of the wing 29 in operation is indicated by an arrow 36.
  • Essential for the function of such a wing 29 is its intake surface 37 facing the perforated plate 30, which is front in the direction of rotation, and its connected, in the direction of rotation rear saponification surface 38.
  • the intake surface 37 is arranged at an acute angle to the surface 39 of the perforated plate 30 , flat surface, the inclination of which is selected such that it gives the component which has already been mixed and pre-homogenized by the mixing screw 12, a movement component in the axial flow direction and it through the perforated plate 30.
  • a significant part of the product gets into the space 40 between the perforated plate 30 and the flat saponing surface 38 opposite to it and parallel to it, due to the wedge action of the pull-in surface 37, and is compressed into a thin layer.
  • the product is subjected to an ointment effect and the dispersion 27 contained therein is evenly distributed.
  • a splitting tool 41 with three wings 42 protruding in the radial direction is connected upstream of the calving tool 28. These are arranged offset to the wings 29 of the ointmenting tool 28 in the circumferential direction by 60 0 each and cause a shifting of the product before it is exposed to the action of the ointmenting tool 28. This improves the homogenizing effect.
  • the perforated plate 30 is not followed by a cutting tool 31, for example in order to obtain a marbling of the soap.
  • the third variant of the homogenizing device shown in FIG. 6 has two perforated plates 30, 43.
  • the second perforated plate 43 is preceded by a saponification tool 28 and the latter by a conversion tool 41.
  • the first perforated plate .30 q is arranged immediately after the mixing screw 12 (not visible in FIG. 6) and has holes 35 of larger diameter than the second perforated plate 42. This improves the homogenizing effect.
  • a perforated plate 30 with holes 35 of larger diameter is preceded by a first balancing tool 28, and in a second stage a perforated plate 43 with holes 44 of smaller diameter is preceded by a second balancing tool 28. Furthermore, in the second stage, a salvaging tool 41 is connected upstream of the calving tool 28 and a cutting tool 31 is connected downstream of the perforated plate 43.
  • the homogenizing effect of such a homogenizing device 20 can be improved by increasing the number of stages lined up.
  • two such levels have already proven to be very effective.
