W O 92/04058 P~/US91/0573 2090~7~ - 2 -Prefe1ably, a rotary vane Is arranged between two chambers which define a filling section and a delivery secl:ion of a compact disinfection or sterilisation unit. The filling section can be formed by a chamber o~
semicylindrical shape, the content of which is emptied into the chambar 0c the delivery section during a forward and/or backward movement of the rotary vane through at least approximately 180. Tllis design of the filling sluice allows large dimensions of the sluice housing, with the result tha~ high throughput quantities can be moved during one sluice operation. Furthermore, a disinfection of the sluice chambers consisting of only a few parts can be carried out reliably by means of steam, water and/or other solutions. A
repeated opening of the ~illing sluice for the introduction of infectious waste, with subsequent treatment, for example in a disinfection or sterili-sation unit, therefore takes place without the risk that infectious germs willbe raleased.
An inflatable sealing element guarantees a wear resistant sealing closure by the rotary vane, the sealing function being achieved even without an exact adjustment of the position of the rot2ry vane. A desirable expand-ability of the sealing element can be obtained by designing the sealing element with a tubular extension. Because the sluice chambers are subjected to steam, the sealing element preferably consists of a heat-resistan~
plastic.
A simple constructive design o~ the rotary vane can be obtained by mounting this on a vertical mid-axis. The rotary vane can then consist o;
two vane blades of symmetrical design. The assembly and maintenance can be simplified by the use of a two-part drive shaft consisting of an uppar and a lower shaft.
Further embodiments of the inven~ion are to be taken ;rom the ~ollowing description and the appended claims.

Figure 1 shows a filling sluice w1th a sluice housing 1, In wnlcn are arranged two laterally adjacent chamber sections separable from one another via a sealingly closing partition wall. In the preferred embodiment illustrated. the two chamber sections are ~ormed by a filling chamber 2 and a delivery chamber 3. The two chambers 2, :3 are trough-shaped and are each sealingly closable relative to the outside via a cover 4, 5. The sealingly closing partition wall is formed by a rotary vane 6 which i5 mounted rotatably about a vertical mid-axis. The rotary vane 6 comprises two vane blades 7, 8 (see Figure 4) spanning a separation surface, the outer circum-ferential line of which exLends as far as the inner wall 9 o~ the sluice housing 1 in the area of the parting plane between the filling chamber 2 and delivery chamber 3.
As can be seen especially from Figure 2, the rotary vane 6 carries a continuous sealing element lO which is inflatable in order to ensure a temporary sealingly closing bearing of the rotary vane 6 against the inner wall 9. To receive the sealing element 10, the rotary vane 6 has a conti-nuous edge slot 11, into which the sealing element 10 is laid. The sealing element 10 comprises an outwardly directed tubular extension 12 which expe-riences a change of shape during inflation, with the result that the sealing element 10 is pressed against the inner wall 9. The change of shape is il-lus,trated by anextension 12 shown in broken lines in Figure 2. Heal-resi-stant plastic is preferably provided as the material for the sealing element 10.
In addition to the closing position of the rotary vane 6 shown in Figures 1 and 3, the latter can be rotated forwards and/or backwards through at least approximately 180. The sluice housing 1 is made semi-cylindrical for the filling chamber 2, specifically with a size and curvature matched tc the pivoting circle 13 o~ the rotary vane 6. The rotary vane 6 can conse-quently move through the filling chamber 2 and empty the waste introducer there into the delivery chamber 3.
To execute the rotational movemen;, the rotary vane 6 is couplec to an upper sha~t 14 and a lower sha~t 15. The sha~t stem a~;orns th-possibility of mounting manual, electrical. hydraulic or pneumatic ~riv^
elements 16. For simple assembly and maintenance, the rotary van^ 6 lS
~aslened to the sha~ts 14, 15 with aouble eccentricily in tne axial direc;-ion and is equipped with slightly angled vane- blades 7, 8 ~see Fiaure 3,.

Each chamber has nozzles 17, 18 for flushing out the chambers 2, 3 with water and/or for admitting them to steam. If appropriate, solutions assisting disinfection can al50 be sprayed in. The nozzles 18 for the jets of water or solution are preferably designed as flat jet nozzles and are directed to the rotary vane 6 in the delivery chamber 2. Both chambers 2, 3 are connected to a condensate outflow 19 for discharging the steam and water introduced by the no~zles.
The shape of the delivery chamber 3 need be matched to the rotary vane 6 only to the extent that it is possible for the rotary vane 6 to swing between the closing positions. The delivery chamber 3 serves as a store for collecting the sluiced-in waste in order to transfer it to a treatment portion of a following appliance. For this, the delivery chamber is made funnel-shaped at the bottom and is equipped with a reciprocating feeder 2û. The filling sluice can form the infeed portion of a compact disinfection or sterilisation unit, in which the infectious waste is treated thermally along a conveyor zone. If a prior comminution of the waste is necessary for this treatment, a comminuting device 21 can be connected directly to the bottom of the delivery chamber 3. Furthermore, the delivery chamber 3 can be connected to the atmosphere via a mem-brane-fiIter element.
The sluice housing 1 preferably consists of high-grade steel and can be made heatable.
The sluice operation with the filling sluic2 described above can be carried out as follows;
The rotary vane 6 is brought into the closing position, and a sealed-off separation between the filling chamber 2 and delivery chamber 3 is obtained by inflating the sealing element 10. The filling chamber 2 is cleaned and disinfected via the injection points 17, 18. The cover 4 of the filling chamber 2 Is thereafter opened and the infectious waste introduced. After this infeed has ended, the cover 4 is closed and th? air bled fro~ the sealing element 10, with the resul~ tha: the sealingly closing engagement of the rotary vane 6 with the inner wdl 1 9 of th^
sluice housing 1 com--s loose. The rotary van? 6 is then rotated forwaras or backwards, during which the vane blade 7, 8 rotaling into the fillino chamber 2 pushes the introduced waste in front of it and throws it into tns delivery chamDer 3 opened as a result Gf the rota~ional moveme m G' U~STITUTE ~HEI

the rotary vane 6. After a rotation of approximately 180, the rotary vane 6 is in the closing position on the opposite side. The sealing element lO
is thereupon inflated, in order once again to obtain a sealingly closing separation of the emptied filling chamber 2 from the delivery chamber 3.
The filling chamber 2 is then cleaned and disinfected again. Before every sluicing operation, the side of the rotary vane 6 facing the delivery chamber 3 is cleaned. The filling chamber 2 can then be filled again and further sluice operations carried out accordingly.
The actuation of the filling sluice is independent of the further treatment of the waste. Only the sluiced-in quantities need be matched to the receiving capacity of the intermediate store formed by the delivery chamber 3.
Although the invention has been described in connection with what is presently considered to be the most practical and preferred embodiment, it is to be understood that the invention is not limited to the disclosed embodiments, but rather, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
