    WO 2013/139362 PCT/EP2012/054751 1 TITLE OF INVENTION Recess plate TECHNICAL FIELD The invention relates to a recess plate, that is designed for packing a plurality of specimens 5 including the recess plate into a pack between a stationary head piece and a movable end piece of a filter device, wherein at least one of adjacent specimens has a recess in a base body of the recess plate, that forms a filter chamber between the adjacent specimens, wherein the filter device has a filter cloth between the adjacent specimens for retaining a solid content of a suspension as a filter cake, and allowing a remaining liquid fraction of 10 the suspension to pass as a filtrate, and wherein the recess plate has a fluid pipe for discharging the filtrate out of the recess plate, that runs along the slender edge, a fluid duct that connects the fluid pipe to the filter chamber, and an extension, that is connected to a slender edge of the base body. The recess plate mentioned above is commonly known, inter alia from DE 103 04 004. 15 Furthermore, JVK Filtration Systems GmbH/Germany, supplier of recess plates, is known to have combined two base bodies of size 1200 x 1200 mm and installed the same to a large filter device. BACKGROUND ART The known recess plates, in particular made of polypropylene, allow for building a filter 20 device that exceeds the production dimensions of a common injection moulding process, and the dimensions of common transportation facilities. In the known recess plates, the extension that is connected to the base body is a second base body, both base bodies comprising respective recesses and fluid ducts for piping the suspension into the respective filtrate chambers, and the filtrate out of the same. The known recess plates use support 25 frames for supporting the base bodies and keeping the base bodies in position. Further commonly known recess plates comprise fluid pipes for several fluids, in particular for the suspension, for the filtrate, for a washing liquid, for a drying gas, and for a squeezing fluid, the fluid pipes distributing the respective fluid along a slender edge of the WO 2013/139362 PCT/EP2012/054751 2 base body to several inlets into the respective filter chamber, or collecting it from several outlets out of the filter chamber. Within the known recess plates, these fluid pipes either are formed inside the base body, or inside the extension, or externally flanged to the recess plate. 5 Where overall dimensions of a filter device are commonly restricted, both the support frames, the respective connecting device between the base body and the extension, and the fluid pipes of the known recess plates require space, thus reducing the potential remaining effective filter surface of the recess plate. PROBLEM TO BE SOLVED 10 It is an object of the invention to enlarge the effective filter surface of the recess plate. SUMMARY OF INVENTION Based on the known recess plate, according to the invention it is suggested that the fluid pipe runs between the base body and the extension. Forming a fluid duct between the base body and the extension reduces the space required inside the base body or inside the 15 extension, and thus enlarges the possible effective filter surface of the recess plate. In a recess plate according to the invention, the extension may be a second base body, having a second fluid duct that connects the fluid pipe to a second filter chamber. The effective filter surface of such recess plate is larger than the respective value of one single base body. A recess plate according to the invention may further have extensions on more 20 than one slender edge of the base body, and more than one extension may be further base bodies. In particular, a recess plate according to the invention may comprise three base bodies in line, or four base bodies arranged in tiles. Preferably, in a recess plate according to the invention, the extension is clipped to the base body. Connecting the extension to the base body thus requires no-external means, or at 25 least reduces the demand for externally connecting force. Clipping may be performed by forming clipping means directly to the base body and/or to the extension, or by separate clipping means either inside the fluid duct, or gripping the slender edge of the base body and/or of the extension.
    WO 2013/139362 PCT/EP2012/054751 3 Further preferred, a recess plate according to the invention has a support, running along the fluid pipe, that supports the recess plate. Stiffness of such recess plate is easily increased. Such recess plate according to the invention preferably has a cavity inside the support for piping the fluid. The support being a pipe inserted into the fluid pipe, and piping the fluid, 5 reduces the risk of leakage of the fluid out of the fluid pipe. Furthermore, in such recess plate according to the invention, the support is clipped to the base body and/or to the extension. Clipping the support into the base body or into the extension simplifies assembling the recess plate. In a pack of a filter device, the recess plates according to the invention are vertically 10 stacked on top of each other or hanging side by side. The filter device is secured by hydraulic force, by the weight of the stacked recess plates and/or by mechanical means. Each filter chamber is equipped with at least one filter cloth, but may be equipped with two filter cloth, where in the first case the suspension is piped into the recess of one recess plate and permeating the filter cloth to the other, and in the latter case filled in between the filter 15 cloths and permeating to both adjacent recess plates. In such filter device, recesses may have movable membranes, the membranes and the respective recesses enclosing a squeezing chamber, that may be loaded with a squeezing fluid for mechanically pressing the remaining filter cake. In such filter device, recess plates according to the invention are made of plastics, e.g. polypropylene (PP), or of metal, e.g. aluminium or steel. 20 Further in such filter device, the filter chamber may be formed by two adjacent recesses, or by one single recess adjoining to a face of a recess plate according to the invention, with no recess. Furthermore, the pack may contain a sequence of identical recess plates according to the invention, in unchanging orientation, a sequence of identical recess plates according to the invention, in changing orientation or a sequence of alternating recess plates 25 according to the invention. Accordingly, recess plates according to the invention may have two recesses, one recess or even no recess at all.

The first recess plate 1 according to the invention, shown in figures 1a and lb, has a base body 2 and an extension 3, that is connected to a vertical slender edge 4 of the base body 2. The first recess plate 1 is part of a first filter device, having a stationary head piece and a 20 movable end piece, and a pack, of first recess plates 1 and other recess plates. In the pack, the first recess plates 1 and other recess plates are hanging side by side in an alternating sequence. The filter device is secured by hydraulic force. Each filter chamber is equipped with two filter cloth, where the suspension is filled in between the filter cloths and permeating to both adjacent recess plates 1. The first recess plates 1 and the other recess 25 plates are made of polypropylene. Apart from the first recess plate 1, the first filter device and it's further parts are not shown. The base body 2 of the first recess plate 1 has recesses 5 on the front face, and on the back face. And the first recess plate 1 - a so called "membrane plate" - has a movable membrane 6, attached to each of the recesses 5. The membranes 6 and the respective 30 recesses 5 enclose two squeezing chambers 7, that may be loaded with a squeezing fluid WO 2013/139362 PCT/EP2012/054751 5 for mechanically pressing the remaining filter cake. The other recess plate (not shown) - a so called "chamber plate" - of the first filter device is basically similar to the first recess plate 1, but has no membranes attached to the recesses 5. Attached to the base body 2, the first recess plate 1 has two filtrate shoes for discharging 5 the filtrate from the filter chamber into a fluid duct 9, that opens into a fluid pipe 10 running along the slender edge 4 between the base body 2 and the extension 3. The fluid pipe 10 connects to a filtrate drain 11 in the extension 3, that runs through the pack, back to the head piece. Both the base body 2 and the extension 3 have recesses 12 running along the slender 10 edge 4, that form the fluid pipe 10. The base body 2 has outer check rails 13, that protrude from the slender edge 4. The extension 3 has corresponding inner profiles 14, that protrude towards the base body 2, and that fit between the check rails 13 of the base body 2. Two sealing elements 15 are clamped between the check rails 13 and the corresponding profiles 14, sealing the fluid pipe 10 from the ambience of the first recess plate 1. The base 15 body 2 and the extension 3 of the first recess plate 1 are clipped together by means of the sealing elements 15 and connected by an external frame (not shown). The second recess plate 16 according to the invention, shown in figures 2a, 2b and 2c, has a first base body 17 and (as an extension) a second base body 18. Apart from different geometries, the second recess plate 16,is part of a second filter device that resembles the 20 first filter device mentioned above, and the base bodies 17, 18 of the second recess plate 16 resemble the base body 2 of the first recess plate 1. Apart from the second recess plate 16, the second filter device and it's further parts are not shown. Basically identical features of the second recess plate 16 and it's base bodies 17, 18 are marked according to the first recess plate 1. 25 The base bodies of the second recess plate 16 each have two fluid ducts 19 for discharging the filtrate from the respective recesses into a common fluid pipe 20 between the base bodies. From the fluid pipe 20, the filtrate is discharged to the ambience, and to a collecting hutch (not shown) underneath the second recess plate 16.
    WO 2013/139362 PCT/EP2012/054751 6 The third recess plate 21 according to the invention, shown in figure 3, is part of the second filter device, basically resembles the second recess plate 16, and forms the pack in an alternating sequence with the second filter plate. Whereas the second recess plate 16 is a so-called "chamber plate", having no membranes, the third recess plate 21 is a so-called 5 "membrane plate". The fluid pipe 22 of the third recess plate 21 connects to fluid ducts 23 for distributing a squeezing fluid into the respective squeezing chambers 24. Figure 4 shows a detail of an alternative geometry for connecting the base body 25 and the extension 26 of a fourth recess plate, that is basically similar to the first recess plate 1, but further not shown. The check rails 27 of the base body 25 and the profiles 28 of the 10 extension 26 both are barbed and interlock when assembling the fourth recess plate. Figure 5 shows a detail of a further alternative geometry for connecting two identical base bodies 29 of a fifth recess plate, that are basically similar to the base body 25 of the fourth recess plate, but further not shown. Each base body 29 has a barbed check rail 30 corresponding to a barbed profile 31 of the respective other base body 29. 15 Figure 6 shows a detail of a further alternative geometry for connecting two identical base bodies 32 of a sixth recess plate, that is basically similar to the fifth recess plate, but further not shown. The check rails 33 and the profiles 34 of the sixth recess plate are not barbed. The sixth recess plate has two sealing elements 35 between the corresponding check rails and profiles.
