Definitions
- the invention relates to a centrifuge according to the preamble of claim 1.
- Separators with separator disc packs show the DE 36 07 526 A1 or the DE-OS 19 09 996 or the DE 10 2004 037 925 A ,
- Separator plates are commonly made of stainless steel. They are usually made of a relatively thin sheet metal, have a conical shape and are combined at a central passage opening plate holders to plate stacks. By means of point or lug-shaped spacers they are axially spaced from each other, so that forms a separation gap between them. Rising channels, which enforce the plate packages usually axially parallel to the axis of rotation of the centrifuge, are used to supply a product to be processed in the gaps between the separation plates, where the product clarified in the centrifugal field of solids and where the liquid may also be in a light and a heavier liquid phase is separated.
- the separating plates of the separating plate stack are provided, at least over an axial region of the separating plate stack or the entire separating plate stack, with one or more dormers each having an opening passing through the separating plate, the dormers and the openings form one or more flow channel (s) in the disk package, and the dormers are each formed as being formed in the conical separation plates at the top and protruding into the disk gap.
- the dormers each as in the conical separating plate (in vertical orientation) introduced upward and projecting into the plate gap forms forms whose height increases radially from the inside to the outside and each having in their radially outer region of the opening.
- This variant can be easily realized on the separation plates by embossing and cutting, drilling or punching in the region of the openings of the dormers.
- FIG. 10a and 10b each show a schematic representation of a once clarifier ( Fig. 10a ) and once as a separator ( 10B ) formed centrifugal drum 1, in each of which a Trenntellervers 2 is inserted.
- the function of such nozzle separators with an inlet 3 and processes 4, 5 and 4, 5, 6 has long been well known and therefore needs no further explanation.
- FIG. 3 shows a schematic representation of a half of a separation plate package according to the invention 2 from stacked conical separation plates 7, which preferably consist of a steel sheet material and in Fig. 1 and 2 are shown.
- the Trenntellerwovene 2 are placed on a central and possibly contoured opening 15 on a correspondingly shaped plate holder (not shown here).
- the separation plates 7 may each have one or more circumferentially distributed openings, which in interaction with the plate stack or separator plate package form at least one or more riser channels 8a, b,..., One of which Fig. 10b is indicated.
- the separating plates 7 are arranged axially spaced from each other by means of spacers 9, so that between each of them a plate gap 14 is formed, which is particularly well in Fig. 7 can be seen.
- the spacers 9 are here exemplified as radially extending tabs, which the separating plates 7 and thus also the separator plate column 14 in Divide sectors 10a, 10b, ..., which in each case again into a lying in operation - ie when rotating the Separatortrommel - behind the spacers half I and a lying in the direction of rotation before the spacers half II is subdivided.
- one of the riser channels 8a, 8b is preferably arranged in each of the sectors 10, preferably - as in FIG Fig. 1 shown - viewed in the preferred direction of rotation U, in the directly behind the spacers 9 arranged half I.
- the separating plates 7 are further provided with at least one region of the axial length or over the entire axial length or vertical axis of rotation, the height of the separator plate stack each with one or more dormers 11, each having at least one opening 12 passing through the respective separation plate 7.
- the dormers 11 are each formed as in the conical separating plate 7 in the vertical axis of rotation upwards introduced features whose height increases radially from the inside outwards and each having in their radially outermost region the opening 12, which - as in Fig. 4 and 5 to recognize, preferably the entire radially outer edge region of the dormers 11 forms.
- the dormers 11 are sized and arranged offset in the stacked separation plates 7 to each other that form through the dormers 11 and the openings 12 and by their interaction the flow channels 13 ( Fig. 3 . 4 . 5 ), which pass through the Trenntellerver 2 or at least a portion of the separating plate 7 of the Trenntellervers 2 radially outwardly and open outward from the Trenntellervers 2.
- a plurality of such flow channels 13 are formed in the separation plate package in the direction of the axis of rotation or in the vertical direction in the vertical axis of rotation ( Fig. 3 . 5 ).
- a plurality of dormers 11a, 11b, 11c which are distributed over the circumference, are preferably also formed in each separating plate 7, so that a plurality of flow channels are formed circumferentially distributed.
- one of the dormers 11a, 11b,... Or one of the dormers and thus also one of the flow channels 13 is formed.
- the dormers are preferably in the sector half II, which lies in front of the spacers 9 in the direction of rotation U respectively.
- the distribution of the dormers 11 is such that over the entire vertical height flow channels 13 are formed in Trenntellervers 2. But it is also conceivable to provide axially individual separating plate 7 without dormers 11.
- a flat design of the dormers is advantageous so that the distance between the plates is not too large.
- the separation plates 7 of the separator plate stack 2 are not formed the same, since the dormers 11 in the region of each flow channel 13 from the inside to the outside aligned openings 12 must form. Due to modern computer-controlled production methods, this offset from separating plate 7 to separating plate 7 introducing the dormers 11 but easily possible.
- a short cut is introduced into the separating plates 7 and then or in front of them, the forms / dormers 11 are formed in the separating plates 7 by an embossing process.
- the choice of the size of the openings 12 provides a simple way to influence the completion speed of the solid from the plate package (see Fig. 6 ).
- FIGS. 7 and 8 illustrate that the dormers can either be rounded or roof-like with an upper edge 16 can be formed.
- the heavy phase H which flows from the inside to the outside at the bottom of the plate, collects in the dormers 11 with the openings 12 and is guided through the flow channels 13 from inside to outside. It is advantageous if the dormers 11 have a radially increasing from the inside outward height.
- the dormers 11 are preferably arranged or formed in the regions of the sectors 10 in which the heaviest phase of the largest flow is to be expected and where its effect is greatest.
- the disk pack can also have no riser or riser channels on other radial position.
- the dormers 11 and openings 12 are arranged on the respective first lower separating plate of a section with dormers 11 and openings radially in height of the riser channels.
- the dormers 11 of the respective first lower separation plate in a section of separation plates with a dormer not more inside than 25% of the radial extent of the separation plates, preferably not further inside than 1/3 of the radial extent of the separation plates arranged to sufficient solids derive.
- the dormers 11 of the respective first lower separating plate are arranged in a section of separating plates with a dormer not more outwardly than 1 ⁇ 2, preferably 2/3 or more preferably 3 ⁇ 4 of the radial extent of the separating plate, so that a particularly good effect is given ,
- the dormers 11 each relative to the respective conical dividing plates 7, in which they are formed in front of upward and form upwardly protruding forms.
- centrifugal drum 1 Separator disc package 2 Intake 3 procedures 4, 5, 6 separator disc 7 rising channels 8 a, b, ... spacer 9 sectors 10a, 10b, ... half I, II believe 11 opening 12 channels 13 plate gap 14 opening 15 edge 16
