Definitions

  • the invention relates to a mixer kneader for carrying out mechanical, chemical and / or thermal processes with at least two axially parallel rotating shafts, disk surfaces with kneading bars arranged on their periphery being provided on the one shaft referred to as main shaft, which are coated by kneading bars which are on disk surfaces are arranged on the other shaft referred to as the cleaning shaft, the kneading bars of two adjacent disk surfaces on the main shaft or on the cleaning shaft maintaining a distance from one another through which the disk surface with the kneading bar on the cleaning shaft or the main shaft passes.
  • Such a multi-spindle mixing and kneading machine is known, for example, from CH-A-506 322.
  • One of the shafts is provided with radial disk elements and axially aligned kneading bars arranged between the disks and is referred to as a disk shaft. Kneading elements shaped like frames engage between these disks and are arranged on the second parallel stirrer shaft. These kneading elements clean the discs and kneading bars of the disc shaft.
  • the agitator shaft In order to achieve a reasonably sufficient cleaning of the disc surfaces, the agitator shaft must rotate faster than the disc shaft by an intended speed ratio. This speed ratio depends primarily on the number of kneading bars on the disc elements, since the kneading elements have to intervene in the spaces between the kneading bars. This results in an insufficient cleaning effect of the pane surfaces, which in turn has a negative effect on the heat transfer to the product to be treated.
  • star-shaped or cross-shaped elements are placed on two shafts rotating in the same direction and have axially extending rods on their outer circumference. These elements can only be used for stirring, but no mixing or kneading effect can be achieved.
  • a mixing device is known from Patent Abstracts of Japan, vol. 13, no. 29 (C562) 3377, January 23, 1989, in which elliptical disk elements are seated on two adjacent shafts which carry bars at their outer ends. With these elliptical disk elements, there is only a small area for heat transfer.
  • a mixer kneader of the type mentioned at the outset is known from EP-A-0 460 466 with the filing date 24.05.91, the priority date 05.06.90 and the publication date 11.12.91.
  • the present invention has for its object to significantly improve the cleaning of all areas and parts within the mixing kneader and at the same time the kneading effect exerted on the product.
  • thermal treatment of the product there is also the task that the heat exchanger area within the mixing kneader is increased and the heat transfer to the product is significantly improved.
  • wings are formed on both sides of the kneading bar, which run radially at a short distance from the disk surfaces of the main shaft or cleaning shaft, and that the disk surfaces of at least the main shaft are sawtooth-like on their outer circumference or are provided with wavy indentations.
  • the disk surfaces are sawtooth-shaped, or they have wavy bulges.
  • the carrier for the kneading bars on the cleaning shaft does not necessarily have to be designed as a disk surface.
  • the kneading bar and cleaning shaft could also be connected by a simple stem that can slide through the above-mentioned distance of the kneading bars of two adjacent disc elements on the main shaft.
  • pane surfaces are preferable because they contribute to increasing the heat exchange and improving the kneading effect.
  • the distance between the kneading bars of adjacent disk elements of the main shaft in turn causes the disk surfaces of the cleaning shaft or an above-mentioned stem to be in gap with the disk surfaces of the main shaft. Even the disk surfaces or the stem are preferably arranged centrally between two disk surfaces of the main shaft. It goes without saying that if the kneading bars of the main shaft and cleaning shaft are preferably identical, not only are two adjacent kneading bars of the main shaft spaced apart, but this distance is also formed by two adjacent kneading bars of the cleaning shaft, but offset, by which then the Disc surface of the main shaft strokes.
  • kneading bars are preferably of identical design, this can also apply to the disc surfaces of the main shaft and cleaning shaft, but they can also be designed differently, depending on the user's request, so that product transport through the cleaning shaft is different from that through the main shaft.
  • the invention leaves many possibilities open here.
  • the main shaft and cleaning shaft rotate in the same clockwise direction.
  • the disc or cleaning elements according to the invention also allow the main shaft and Cleaning wave in the counterclockwise direction. It is also possible to rotate the main shaft and cleaning shaft at the same or different speeds. When rotating, whether in the same direction or in opposite directions, at the same speed, the number of kneading bars on the main shaft should correspond to that on the cleaning shaft. This enables the most economical cleaning for this speed without interfering with the kneading bars.
  • the number of kneading bars arranged on the main shaft and on the cleaning shaft should be inversely proportional to the speed ratio. For example, if the speed ratio of the main shaft to the cleaning shaft is 1: 4, then four kneading bars are arranged on the main shaft and only one kneading bar on the cleaning shaft. Eight kneading bars can also be provided on the main shaft and two kneading bars on the cleaning shaft.
  • the speed ratio is odd, for example 1: 1.25, five kneading bars are arranged on the main shaft and four kneading bars on the cleaning shaft.
  • the present mixer kneader is extremely flexible.
  • the main advantages are improved self-cleaning, a larger specific heat exchange surface, a more effective one Surface renewal with diffusion-determined evaporation processes, a more intensive mixing effect with gentle kneading and less compacting as well as a narrow residence time spectrum.
  • a mixer kneader P has gem.
  • Fig. 1 a housing 1, which consists of several housing sections 1 a, 1 b and 1 c. The housing sections are coupled to one another by corresponding flange connections 2.
  • a feed nozzle 3 for a product to be treated in the mixing kneader and in the housing section 1 c an outlet nozzle 4 for the treated product.
  • the product is transported from the feed nozzle 3 to the outlet nozzle 4 by means of two shafts 5 and 6 and kneading and transport elements 7 arranged thereon.
  • the product is mixed and kneaded, and preferably a thermal treatment takes place.
  • the shafts 5 and 6 and optionally also the kneading and transport elements 7 and, not shown in more detail, the housing wall 8 are heated.
  • connections 9 and 10 are provided, these connections 9 and 10 around corresponding outlet nipples 11 and 12 for the heating medium guided through the shafts 5 and 6 are arranged. Appropriate routing of the heating medium in the lateral surfaces of the shafts 5 and 6 and a corresponding return through the outlet nipples 11 and 12 are prior art and are therefore not described further.
  • shaft lugs 13 and 14 connected to the shafts 5 and 6 pass through a lantern 15, a stuffing box 16 and 17 being provided against the housing 1 for sealing the shafts 5 and 6, respectively.
  • the shaft journals 13 and 14 are coupled to one another outside the lantern via corresponding gear elements 17 and 18, for example gear wheels, the gear element 17 being connected to a drive 20 via a gear 19. Via this drive 20 and the gear 19, at least the gear element 17 is rotated, which is transmitted to the shaft 5.
  • This rotary movement can be transmitted to the gear element 18 in the same or opposite directions and at the same or different speed.
  • Corresponding transmission gears are customary in the trade and should not be described in more detail here.
  • shaft 5 is also referred to below as the main shaft and shaft 6 as the cleaning shaft.
  • Kneading and transport elements 7 are placed on each shaft 5 and 6, which have disc surfaces 21 as the basis for the respective shaft 5 and 6.
  • Various exemplary embodiments of disk surfaces 21 are shown in FIGS. 5 to 7.
  • FIGS. 13 and 14 and 18 and 19 A further variant of a disk surface 21 e can be found in FIGS. 13 and 14 and 18 and 19. There, a disk surface circumference 23 is no longer circular, but has wavy indentations 24.
  • the kneading and transport elements 7 on the main shaft 5 as well as on the cleaning shaft 6 are identical except for the configuration of the disk surfaces 21, they should be provided with the same reference numbers below. Of course, this leaves open within the scope of the present invention that the kneading and transport elements 7 on the main shaft 5 are configured differently than those on the cleaning shaft 6.
  • an actual support leg 26 sits on the disk surface circumference 23, while wings 27 and 28 protrude from this support leg 26 on both sides of the respective shaft 5 or 6. This then results in a kneading and transport element 7, as shown in particular in FIG. 2, which has a T-shaped configuration when viewed from above.
  • the disk surfaces 21 of the main shaft 5 and cleaning shaft 6 are arranged offset to one another.
  • This offset is preferably such that a disk surface 21 of the cleaning shaft 6 engages approximately centrally between two disk surfaces 21 of the main shaft 5.
  • this offset can also occur off-center, in which case knee spaces 29 of different widths then arise.
  • the design of identical knee spaces 29 is preferred.
  • kneading bars 25 are inclined in relation to the axial direction of the shafts 5 and 6, respectively. This improves the transport effect. Furthermore, arrows 30 and 31 indicate that the main shaft and cleaning shaft rotate in opposite directions.
  • the number of kneading bars on the disc surfaces of the cleaning shaft is normally the same as the kneading bars on the Disc areas of the main shaft in the inverse ratio of the speeds of both shafts.
  • the traces of the main shaft's kneading bars on the cleaning shaft can be identical, the number of kneading bars on the main shaft can also be reduced, if desired.
  • FIGS. 8 and 9 The advantageous cleaning effect of the present invention compared to, for example, CH-PS 506 322 can be clearly seen when comparing FIGS. 8 and 9.
  • Fig. 8 hatched, not cleaned surfaces 32 are still present on a disk surface 21 to a relatively large extent.
  • 9 on the other hand, it can be seen that there are no more contiguous, uncleaned surfaces, but that only certain areas 32 a near the main shaft 5 and certain areas 32 b around the kneading bars 25 have not been cleaned.
  • the areas which have not been cleaned are thus so minimal that the heat exchange between the disk surface 21 and the product to be treated is improved to a very excellent degree.
  • FIGS. 10 to 14 differ from those just described in that the main shaft 5 is synchronized with the cleaning shaft 6. This is shown by the two arrows 30 a and 30 b. Furthermore, both shafts 5 and 6 run at the same speed, so that the number of kneading bars 25 arranged on the disk surfaces 21 is also the same. Only the disk surfaces 21 are on the two Shafts 5 and 6 are offset from each other or stand on a gap.
  • the wavy indentations 24 in the disc surfaces 21 e acc. 13 and 14 allow faster product transport or faster passage of gases or vapors.
