Abstract
The present invention relates to a device for separating liquid and solid material from a mixture, comprising: a filter cloth for allowing through the liquid and holding back the solid material; a carrier belt for supporting the filter cloth with the mixture thereon, wherein the carrier belt is optionally provided with one or more openings close to at least one of the side edges or at least eccentrically thereof; a support construction for supporting the carrier belt movable relative thereto; and a suction box arranged under the support construction and/or on the side of the carrier belt and connected to the optional openings in the carrier belt for extracting liquid from the mixture.
Description
- For many years applicant has marketed devices for separating liquids and solids. A first embodiment thereof is provided with a suction box co-displacing with a filter cloth and making a reciprocating movement.
- In another embodiment side boxes are situated close to a side edge of a carrier belt for the filter cloth, and the liquids are sucked through channels in the carrier belt to the suction boxes. This latter embodiment has the advantage over the above mentioned first embodiment that the suction boxes can be of relatively simple embodiment, since they are placed in stationary position. Due to the arrangement close to the edges the suction boxes are readily accessible for inspection, cleaning and maintenance.
- In this known second embodiment the sealing of the carrier belt relative to the suction box is a problem. The possible solutions to this problem are costly and/or require frequent maintenance.
- The present invention provides a device for separating liquid and solid material from a mixture, comprising:
- a filter cloth for allowing through the liquid and holding back the solid material;
- a carrier belt for supporting the filter cloth with the mixture thereon, wherein the carrier belt is optionally provided with one or more openings close to at least one of the side edges or at least eccentrically thereof;
- a support construction for supporting the carrier belt movable relative thereto; and
- a suction box arranged under the support construction and/or on the side of the carrier belt and connecting to the optional openings in the carrier belt for extracting liquid from the mixture.
- In a preferred embodiment the carrier belt is embodied in plastic, this being recommended for particular chemical compounds since it does not give off any colour to the separated liquid and/or solid material.
- In another preferred embodiment the carrier belt is of rubber, since rubber is extremely wear-resistant and has a long lifespan.
- In the case of determined carrier belts it is recommended to dispose the suction box on only one side thereof, which is of course advantageous in respect of maintenance, inspection and the like.
- Further advantages, features and details of the present invention will be elucidated on the basis of the following description of a preferred embodiment thereof with reference to the annexed drawings, in which:
- FIG. 1 shows a view in perspective of a preferred embodiment of the device according to the present invention;
- FIG. 2 is a cross-sectional view along the preferred embodiment shown in FIG. 1; and
- FIG. 3 shows a cross-sectional view of a further preferred embodiment of the device according to the present invention.
- In a device1 (FIGS. 1,2) a
filter cloth 2 and arubber belt 3 placed thereunder and provided withchannels 4 are trainedround rollers 5,6, at least one of which is driven. Disposed along the edges in stationary position undercarrier belt 3 aresuction boxes 7, 8 which are provided on the underside with a discharge connection 9 respectively 10 for discharging the liquid sucked throughfilter cloth 2, while the suction boxes are provided on the top side withsuction connection 11 respectively 12, whereby a further separation between volatile constituents of the liquid and less volatile constituents thereof also takes place insuction boxes 7, 8. - The liquid is sucked out of mixture M as according to arrows A, B and C into the suction boxes via
openings 13 incarrier belt 3, wherein betweencarrier belt 3 and suction boxes 7 respectively 8 are arrangedseals 14 respectively 15 of wear-resistant material and relatively simple manufacture. - As shown particularly in FIG. 2, the carrier belt is provided on both edges with
heel parts 16 respectively 17 in order to ensure that the liquid enters theopenings 13 via the arrows. The carrier belt is sealed on the upper side relative to the fixedly disposedconstruction 20 usingseals 18 respectively 19. - In a further preferred embodiment as shown in FIG. 3, the
suctions boxes carrier belt 3, wherein the suction boxes are again provided on the underside withdischarge connections 39 respectively 40 for discharging liquid sucked throughfilter cloth 2, said boxes being provided on the top side withsuction connections 41 respectively 42 whereby a separation between volatile constituents of the liquid and less volatile constituents thereof also takes place insuction boxes seals supports suction boxes filter cloth 2,channels heel parts 16 respectively 17, which channels connect onto elongateopening parts suction boxes shoulder parts 48 respectively 49 of a wear-resistant material with a low coefficient of friction, such as for instance teflon, on which thefilter cloth 2 supports and along which this cloth is pulled. - In a further embodiment (not shown) of the present invention suction boxes are disposed in stationary position under and on the side of the carrier belt. This embodiment is therefore a combination of the embodiments shown in FIGS. 1, 2 and3.
- The present invention is not limited to the above described preferred embodiment thereof; the rights sought are rather defined by the following claims, within the scope of which many modifications can be envisaged.
