Definitions
- Centrifuge whose centrifugal drum has a peeling chamber and a hydrohermetic chamber
- the invention relates to a centrifuge with a vertical axis of rotation, the centrifugal drum of which has a peeling chamber which is connected to the separating space of the centrifugal drum via at least one discharge channel and which is provided with a peeling device arranged in the peeling chamber, which clarifies the continuous discharge of a in the centrifugal drum or separated liquid phase, and also has a locking disk which is firmly connected to the peeling device above the peeling chamber and which extends into a rotating disk rotating with the centrifugal drum
- the peeling device is provided with a channel for supplying a barrier liquid into the barrier chamber and the barrier chamber is bounded at the top and the outside by a cover, the free edge of which faces the axis of rotation forms an overflow weir.
- Water or another foreign liquid introduced into the blocking chamber from the outside can be used as the blocking liquid.
- the barrier chamber provided above the sheeting chamber which is also known as the hydrohermetic chamber, prevents atmospheric air from entering the peeling chamber and thus into the liquid phase peeled off from this chamber.
- a centrifuge of the type mentioned at the outset is known (DE 40 14 552 C1), in which deposits of solid can form on the periphery of the barrier chamber during operation and cannot be flushed out even during CIP cleaning. These deposits, provided they are organic in nature, can begin to rot, so that the product passing through the centrifuge can be contaminated.
- the invention has for its object to design a centrifuge of the type mentioned so that deposits of solids on the periphery (on
- Outer bottom) of the barrier chamber with the overflow of the barrier liquid and / or with the downflow of the cleaning medium during CIP cleaning are discharged into the space between the centrifugal drum and the centrifuge housing.
- a second locking chamber cover is arranged, which is offset inward relative to the outer bottom of the locking chamber and with the first cover a flow channel for the removal of solids deposited on the outer bottom of the locking chamber via the Overflow weir forms.
- a directional flow is present during operation of the centrifuge when barrier water is added, which discharges the solid deposited on the outer bottom, on the periphery of the barrier chamber, via the overflow weir.
- Drain pressure of the peeling device of the liquid level in the peeling chamber is shifted radially inwards to such an extent that liquid flows from the peeling chamber over the inner boundary of the overflow into the barrier chamber. This results in an intensive flushing with a flow through the flow channel, which is formed by the two lids, in the barrier chamber. All solids deposited on the periphery of the barrier chamber are rinsed out, so that a hygienically clean hydrohermetic chamber results.
- a liquid phase of the product is passed into a peeling chamber 5 and from there via a peeling device 6 under pressure from the centrifuge.
- a blocking chamber 7 which rotates with the centrifugal drum 2, an overflow 8 being arranged between the peeling chamber 5 and the blocking chamber 7 and forming a partition between the two chambers.
- a blocking disk 9 projects which is connected to the peeling device and is thus arranged in a stationary manner.
- Bore 12 is sealed via an annular space 13 and an outlet 14, e.g. Barrier water, introduced into the barrier chamber 7, a barrier liquid level 15 being formed, which is determined by an overflow weir 16, which is formed by the free inner edge of a cover 17, which delimits the barrier chamber 7 upwards and outwards.
- the free edge that forms the overflow weir 16 is the
- a second blocking chamber cover 18 is arranged between the blocking disc 9 and the first cover 17. This second locking chamber cover 18 is offset inwards relative to the outer bottom 19 of the locking chamber 7 and, together with the first cover 17, forms a flow channel 20 for the removal from the outer bottom of the
- Locking chamber 7 and is guided through the flow channel 20.
- the liquid level in the peeling chamber is displaced radially inward by throttling the discharge pressure of the peeling device so that liquid flows from the peeling chamber over the inner limit of the overflow into the barrier chamber.
- the second barrier chamber cover 18 is connected to the overflow 8 between the peeling chamber 5 and the barrier chamber 7.
- This assembly has an outwardly extending ring flange 21 which is fixed between the first cover 17 and an upper end face 22 of the centrifugal drum 2.
- a sealing ring 23 anchored in a groove of the first cover ice 17 is supported on the ring flange 21.
- barrier chamber cover 18 is provided adjacent to the inside of the first cover 17, so that the flow channel 20 is formed in the form of a gap between these two covers.
