Definitions
- the invention relates to a centrifuge, which has the following: a centrifugal drum, an inlet pipe opening into the centrifugal drum for supplying a centrifugal material into the centrifugal drum and a feed channel for supplying a control fluid into an opening and / or closing section of the centrifugal drum.
- the invention further relates to a method for operating a centrifuge according to the invention.
- a generic centrifuge is known from DE 28 22 478.
- the centrifuge shown in this document has a centrifugal drum with a piston slide, to which a chamber is assigned, which is connected to a hydraulic system via channels in a spindle.
- the product is fed in from above via a central inlet pipe.
- the spindle is at the bottom of the
- Centrifugal drum This design has proven itself in itself, but it reaches its limits if the product area is to be separated from the drive area of the centrifuge and the control elements of the drive and the control elements of the control fluid supply outside the drum (valves, etc.) for hygiene reasons.
- the invention therefore aims to provide a centrifuge in which the control fluid is to be supplied in a particularly structurally simple manner.
- the invention it should also be possible to use the invention to control the product area of the drive area and its control elements, and preferably also of the
- the invention achieves this aim by the subject matter of claim 1.
- the invention differs from the generic prior art in that the feed channel for the control fluid is directly connected to the feed pipe for the
- control fluid supply and the centrifugal line are thus routed together into the centrifugal drum and preferably also run directly next to one another, a structurally separate supply line for the control fluid can be avoided.
- the invention is particularly suitable for a centrifuge in which the
- Centrifugal drum hangs on a centrifuge frame, the inlet pipe for the centrifuged material and the feed channel for the control fluid are jointly guided into the centrifugal drum from above.
- a separate supply of the control fluid from below into the drum is not practical, since it may be necessary to collect the solids separated during the separation process below the drum in a sterile container. This is significantly simplified by the control fluid supply “from above”.
- a double wall is formed on the inlet pipe, the inner pipe section serving, for example, for supplying the centrifuged material and the concentrically outer pipe section serving as the feed line for the control fluid.
- a double-walled tube offers the advantage of a particularly space-saving accommodation of the control fluid and centrifugal material feed lines.
- the control fluid supply preferably serves to actuate a displaceable piston slide for opening and closing solids discharge openings in the centrifugal drum.
- An opening chamber and a closing chamber adjoin the piston slide. Pressurization with the control fluid moves the spool, it is also possible to hold the spool spring-loaded in one of its working positions and to move it into the other working position by building up pressure in the corresponding control chamber.
- a gaseous medium is particularly preferred as the control fluid, preferably
- Fig. 1 is a sectional view of a centrifuge according to the invention with a
- Piston spool which is shown in its open position in the left section of the drawing and in its closed position in the right section.
- centrifuge 1 shows a centrifuge designed as a separator which, in a manner known per se, has a centrifugal drum 2 which is set downwards for separating a
- the centrifuged material or the centrifugal liquid is passed from top to bottom through a central feed pipe 4 into the centrifugal drum 2.
- the centrifugal drum 2 is on a centrifuge frame 6 with a lower one
- the drive section 10 of the centrifuge - which can be embodied in a manner known per se and is therefore not shown in detail here - is arranged above the centrifugal drum 2 in and / or on the centrifuge frame 6 and is via a likewise not shown here in detail - Sealing section 12 sealed in the frame extension 8 against the centrifugal drum 2.
- the centrifugal drum 2 is thus structurally separated from its drive gate and its control elements.
- a container lid 14 is flanged to the lower end of the frame extension 8 and is penetrated centrally by the inlet pipe 4.
- the container lid 14 here has a substantially radially formed bore 16, which serves as a discharge channel for a liquid phase derived from the centrifugal drum 2 by means of a peeling disc 18 from a peeling chamber 20.
- the bore 16 opens into a drain pipe 22.
- a centrifugal drum 2 is formed in its upper region surrounding the upper container jacket 24, which serves as the upper end of a conical container 26 here for taking up solids, the lower section 28 of the container being removable downwards from the centrifuge and in one Container frame 30 stands.
- the actual centrifugal drum 2 has a distributor 32 surrounding the inlet pipe 4 with a plate pack 34 attached to the outside of the distributor 32.
- the plate pack 34 is located in a centrifugal chamber 36 conically narrowing upwards and downwards, which is bounded at the top by a conically shaped drum cover 38 and at the bottom by a centrifugal chamber floor 40 molded onto the distributor 32 at the bottom.
- the drum cover 38 is inserted into a lower drum part 42 and screwed into the lower drum part 42 with a locking ring 44.
- a displaceably guided, annular piston slide 46 Arranged between the centrifuge chamber floor 40 and the lower housing wall of the lower drum part 42 is a displaceably guided, annular piston slide 46 with an essentially L-shaped wall cross section, to which an opening chamber 48 adjoins at the top and a closing chamber 50 adjoins at the bottom.
- the lower wall of the lower drum part 42 serves as the lower closing chamber floor 52.
- locking springs 54 Between the lower wall of the piston slide 46 and the locking chamber floor 52 - that is to say in the locking chamber 50 - there are arranged locking springs 54 which hold the piston slide 46 in the closed position, in which it holds the solids outlet openings 56 closes in the outer jacket of the lower drum part 42 (right part of FIG. 1).
- the opening chamber 48 is formed between the piston slide 46 and the lower wall of the distributor 32 or the centrifugal chamber floor 40.
- the control fluid is fed into the opening chamber 48 via a control fluid supply line 58 in the distributor 32.
- the control fluid feed line 58 opens into an annular feed channel 60 surrounding the feed pipe 4 between the inner wall of the distributor 32 and the feed pipe 4 inserted into the distributor 32.
- the inner wall of the distributor 32 and the wall of the feed pipe 4 form a kind of “pipe Double wall ", the actual supply channel 60 for the control fluid being the inlet pipe
- the distributor 32 of the centrifuge runs through it in one piece from the upper end region of the centrifuge frame 6 to the lock chamber bottom 52.
- this element is preferably composed of several parts.
- connection 62 Above the upper end region of the centrifuge frame 6, an axial connection 62 enables the centrifuged material to be fed into the feed pipe 4.
- a connection 64 which is directed radially outward here, serves to feed the control fluid - in particular the supply of sterile control air - into the feed channel surrounding the feed pipe 60.
- the centrifugal material is fed in through the connection 62 and the inlet pipe 4 and through an axial bore 66 of the distributor 32 and a bore 68 in the centrifuge chamber floor 40 into the centrifugal chamber 36. Solids are discharged from the centrifugal chamber 36 through the openings 56, and liquid phases through the peeling chamber 20 with the peeling disc 18.
- control air is passed as control fluid through the connection 64 into the feed channel 60 concentrically surrounding the feed pipe 4.
- the control air flows from there O
