Definitions
- the invention relates to an arrangement for the mechanical treatment of water-suspended pulp fibers between two treatment gap forming, relatively rotating and coaxially arranged treatment plates, which are arranged in a closed housing with an inlet and an outlet for the fiber suspension.
- pulp fibers i.
- the treatment plates have a multiplicity of grinding strips, also called knives.
- the treatment plates themselves are each formed by several Mahlgarnituren.
- the refiner can be designed as a disc refiner or cone refiner.
- the treatment plates in Disperger annular, concentrically arranged rows of teeth.
- the treatment plates must be optimally adapted to the pulp to be treated, also to prevent excessive wear of the same.
- the object of the invention is therefore to simplify the construction of such arrangements. According to the invention, this object is achieved in that rotating treatment plates are mounted in the housing and connected via a drive shaft with an existing outside of the housing gear or drive. Due to the separate storage of the rotating treatment plates, the load on the drive shaft can be significantly reduced, which has a corresponding effect on their design and storage. As a result, the required space and the corresponding manufacturing costs are significantly reduced. This in turn allows to store the drive shaft only outside of the housing.
- the drive shaft is designed in one piece with an axis of the transmission or the drive.
- the drive shaft can be completely dispensed with a direct storage.
- the transmission or the drive should advantageously have a drive pin for non-positive or positive reception of the corresponding end section of the drive shaft designed as a hub or a drive hollow shaft for frictionally receiving the corresponding end section of the drive shaft.
- this should be supported on a foundation.
- the transmission and / or the drive should be supported on one, preferably the same foundation.
- the treatment surfaces of the treatment plates may be perpendicular to the axis of rotation or conical to the axis of rotation. It is also possible that several treatment gaps are present in the housing. In this case, to fully exploit the advantages of the invention, the rotating treatment plates of the treatment gaps should be driven by a common drive shaft.
- the invention is applicable to arrangements with at least one treatment gap for grinding the fibers or at least one treatment gap for dispersing the fibers.
- FIG. 1 shows a longitudinal section through a conventional grinding arrangement
- Figure 2a-c a longitudinal section through various inventive
- Figure 3 a detailed longitudinal section through a grinding arrangement
- Figure 4 a plan view of the housing 4 of the grinding arrangement.
- the closed housing 4 of the grinding arrangement are here, for example, two perpendicular to a rotation axis 15 treatment gaps 1 in the form of grinding gaps, each formed by a fixed and connected to the housing 4 treatment plate 2 and a rotating about the axis of rotation 15 treatment plate 3.
- the annular and coaxially arranged grinding surfaces of the two treatment plates 2, 3 of a grinding gap run parallel to each other, wherein the distance between them is usually adjustable.
- the rotating treatment plates 3 are rotatably mounted in the housing 4 in accordance with FIGS. 2 to 4 and are driven by a common drive shaft 7.
- the two rotating treatment plates 3 according to FIG. 1, as known per se, are fastened to a common disk 16 of the drive shaft 7.
- the grinding surfaces are each formed by a plurality of substantially radially extending Mahlleisten and the intermediate grooves.
- the fiber suspension to be grounded passes via an inlet 5 through the center into one of the two treatment gaps 1 between the two grinding surfaces.
- the fiber suspension passes through the interacting
- the grooves running between the grinding bars likewise have a rectangular cross-section and serve as flow channels for the fiber suspension.
- the groove depth is usually between 2 and 20 mm.
- the drive shaft 7 is driven via a gear 8, for example in the form of a spur or planetary gear by an electric drive 9, wherein gear 8 and drive 9 are arranged outside of the housing 4. Since the rotating treatment plates 2 are rotatably mounted in the housing 4, can be dispensed with a storage in the housing 4 in the drive shaft 7, which greatly simplifies the construction of the grinding arrangement.
- FIGS. 2 a to c show various design options for the coupling of the drive shaft 7 to the transmission 8.
- the drive shaft 7 of the grinding assembly is integral with an axis 10 of the transmission 8. This means that the drive shaft 7 is mounted only in the transmission 8 and so hardly transmits radial forces.
- the drive shaft 7 has no own storage.
- the transmission 8 has a drive journal 1 1 for frictionally receiving the corresponding end section of the drive shaft 7 formed as a hub 12.
- the transmission 8 assumes the complete bearing function for the drive shaft 7 of the grinding arrangement.
- the housing 4 as well as the transmission 8 and the drive 9 are based on a common machine foundation 14.
