Definitions

  • the present invention relates to a device for cleaning a fiber suspension for the paper production of foreign matter contained therein, such as sand, metal parts, glass splinters, bark parts and the like, using a tubular, vertically oriented housing, which is provided with an inlet for the pressurized Introducing the fiber suspension in this housing, further formed at its lower end with an outlet for discharging the foreign matter contained in the fiber suspension and at its upper end with an outlet for discharging the cleaned of the foreign matter fiber suspension.
  • a tubular, vertically oriented housing which is provided with an inlet for the pressurized Introducing the fiber suspension in this housing, further formed at its lower end with an outlet for discharging the foreign matter contained in the fiber suspension and at its upper end with an outlet for discharging the cleaned of the foreign matter fiber suspension.
  • a separation device In order to purify a fiber suspension in the required manner, a separation device is known, by means of which the foreign substances contained in the fiber suspension are removed.
  • This known device consists of a vertically oriented tubular housing, which is formed with a lateral connection, through which the fiber suspension is introduced under pressure into the interior thereof, wherein it flows in this housing in circular movements.
  • the foreign substances such as sand, metal parts, glass fragments, bark parts and the like, which are heavier to the cellulose fibers, are moved radially outwards, whereby they reach the inner wall of the housing and slide downwards along the latter.
  • the cellulose fibers which are lighter in relation to the foreign substances remain in the radially inner region of this housing, moving upward in circular movements.
  • the housing is formed with an outlet through which the foreign matter is discharged from the housing.
  • the housing is formed with a further outlet, through which the fiber suspension freed from impurities is discharged.
  • the housing By moving along the inner wall of the housing foreign matter, the inner wall of a strong abrasion, which ultimately causes the housing wall is broken, whereby this device is rendered inoperative.
  • the housing is formed in its lower region with a jacket through which it is enclosed. By occasionally checking the interior of this jacket, it can be determined if it is empty, from which it is concluded that the housing has no breakthrough or whether it contains a fiber suspension, which is the case when a breakthrough has occurred in the housing. As a result, then this housing or the affected housing part is replaced by a new housing or by a new housing part.
  • the subject invention is based on the object to take measures by which it is possible to easily determine whether a breakthrough has occurred in the housing and furthermore, if necessary, to check the housing wall in a simple manner to see whether it still has a sufficient strength, so that there is no risk of breakthrough or if the thickness of the housing wall due to the abrasions is already so low that there is a risk of breakthroughs, so the housing or a housing part must be replaced.
  • This is inventively achieved in that at least a part of the housing or the lower housing parts or a surrounding sheathing made of a transparent or a transparent material, in particular of a transparent or a transparent plastic material, is or are.
  • the housing is formed in its lower part with at least one sheath, so anyway this is also made of a transparent or transparent material, whereas the inner housing part can also be made of an opaque material.
  • the housing or the lower housing parts and the possibly provided sheaths are made of a transparent polyurethane.
  • the housing or the lower housing parts and the possibly provided sheaths are made of a clear polycarbonate.
  • FIG.1 illustrated inventive device has a vertically oriented tubular housing, which consists of three superimposed and interconnected housing parts 1, 2 and 3 consists.
  • the first housing part 1 is formed with a lateral inlet opening 10, through which a fiber suspension containing foreign substances is introduced under pressure into the interior of the housing.
  • this housing part 1 is a spirally extending guide screen 11, through which the introduced fiber suspension is placed in a circular flow.
  • the second housing part 2 which tapers conically downwards.
  • the first housing part 1 is formed in its radially inner region with a tube 12 which projects into the second housing part 2 and which extends upwards, wherein an outlet opening 20 is located at its upper end.
  • All housing parts 1,2 and 3 or at least the housing parts 2 and 3 are made of a transparent or made of a transparent material. They are e.g. Made of transparent polyurethane or crystal clear polycarbonate. Between the individual housing parts 1, 2 and 3 seals are provided, so that the interior is sealed to the outside.
  • the housing parts 2 and 3 are made of a transparent or made of a transparent material, it can be determined at any time whether their walls are still sufficiently thick to rule out the risk of breakthroughs can. If, in contrast, a lower limit in the thickness is exceeded, the housing part in question is replaced by a new housing part. As a result, on the one hand unwanted interruptions in operation are avoided and on the other hand cost savings achieved because the housing parts can be formed without sheaths.
  • FIG.2 illustrated embodiment differs from the exemplary embodiment FIG.1 in that the housing parts 2 and 3 are formed with sheaths 21 and 31 which have closable openings by means of plugs 22 and 32 and which are likewise made of a transparent or a transparent material.
  • the housing parts 2 and 3 are formed with sheaths 21 and 31 which have closable openings by means of plugs 22 and 32 and which are likewise made of a transparent or a transparent material.
  • the housing parts 2 and 3 may be made of an opaque material, whereas the sheaths 21 and 31 must be made of a transparent material, which then at any time can be determined whether in the housing parts 2 and 3, an opening has occurred.
