Definitions
- the invention relates to a receiving device for at least one shaft sealingly mounted in a housing according to the preamble of claim 1.
- the shaft designed as an extrusion screw is directly surrounded by a seal which seals the shaft against the housing wall of an extruder. This has the consequence that when removing or installing the shaft, for example when the inside of the housing has to be cleaned, the seal can be damaged or pre-damaged as a result of direct contact with the shaft.
- the object of the invention is therefore to avoid such damage or pre-damage when removing or installing a shaft in a housing.
- the receiving device according to the invention for at least one shaft sealingly mounted in a housing with the characterizing features of claim 1 has in contrast the advantage that the shaft is separated from the seal by a protective element, so that there is no direct contact between the shaft and the seal. This effectively prevents damage or pre-damage to the seal when removing or installing the shaft.
- FIGs 2 and 3 the extruder of Figure 1 during the removal of the extruder screws and one
- Sealing unit also in partially sectioned side views.
- the extruder designated by 10 in FIG. 1 is used in the confectionery industry for processing confectionery masses.
- the extruder 10 has a housing 11 which is sealed on one end face with a housing cover 12.
- Two extruder screws 1, 2 arranged parallel to one another are arranged essentially inside the housing 11, the drive shafts 3, 4 of which are located on the side of the housing cover 12 facing away from the housing 11.
- the housing cover 12 has a recess 13 in the form of a Breakthrough.
- a unit 15, consisting of a sleeve-shaped seal housing 16, which encloses a mechanical seal 17, 18 for each extruder screw 1, 2, can be inserted in a sealing manner.
- the seal housing 16 has circumferential collars 19 for each mechanical seal 17, 18 on its inner circumference.
- the collars 19 are guided in circumferential annular grooves 21 of the mechanical seals 17, 18.
- Essentially sleeve-shaped receiving shafts 25, 26 for the drive shafts 3, 4 of the extruder screws 1, 2 can be inserted into the mechanical seals 17, 18.
- the length of the receiving shafts 25, 26 is dimensioned such that when the extruder screws 1, 2 are mounted, an axial play 22 or distance is formed between the end faces of the mechanical seals 17, 18 and the end faces 23 of the extruder screw flights (see detail in FIG. 1). This is achieved in that the receiving shafts 25, 26 protrude somewhat from the mechanical seals 17, 18.
- the receiving shafts 25, 26 have toothings 27, 28 on their outer circumference, via which the extruder screws 1, 2 can be driven by means of a drive (not shown).
- the extruder screws 1, 2 are axially fixed in the receiving shafts 25, 26 by means of fastening nuts 5, 6, which can be mounted on the ends of the drive shafts 3, 4 protruding from the receiving shafts 25, 26.
- the receiving shafts 25, 26 are mounted in a frame 29, which in turn has guide eyes 30, in which guide rods 31 are guided.
- the guide rods 31 are fastened together with an end plate 32 to the housing cover 12 of the extruder 10.
- the unit 15 can be connected to the facing end face 34 of the frame 29 by means of screws 33.
- the design described above causes the receiving shafts 25, 26 to be aligned with the unit 15 and the recess 13 in the housing cover 12.
- the extruder screws 1, 2 are mechanically decoupled from the mechanical seals 17, 18, which means that there are no loads / damage to the extruder screws 1, 2 on the
- Extruder screws 1, 2) in the guide rods 31 are moved away from the housing cover 12 of the extruder 10, the unit 15 being pulled out of the recess 13. Then the screws 33 can be loosened so that the unit 15 together with the mechanical seals 17, 18 are dismantled (FIG. 3).
