[0019] First Embodiment 1. Overview of Management System 100 Fig. 18 conceptually illustrates an example of the management system 100 according to the first embodiment. Fig. 19 illustrates an example of a processing system 110 that is managed by the management system 100. In a representative example of the first embodiment, the processing system 110 includes a filter press apparatus 1. The processing system 110 may be configured only by the filter press apparatus 1, or may include devices and parts other than the filter press apparatus 1.

[0020] 2.Details of filter press equipment 1 to 17 show an example of a filter press device 1 included in a processing system 110. The filter press device 1 includes a filter plate structure 3 as shown in FIG. 1, and has a device configuration as shown in FIGS.

[0021] The filter plate structure 3 shown in Fig. 1 is used, for example, in a single filter press device 1 as shown in Fig. 9. The filter press device 1 shown in Fig. 9 is a device that can dehydrate a solid-liquid mixture (for example, a slurry in which sludge, excavated soil, cement, etc. are mixed in water, etc.) and discharge a solidified material (cake) that is the residue after dehydrating the solid-liquid mixture.

[0022] The filter press device 1 uses a filter plate structure 3 shown in FIG. 1 and the like. The filter plate structure 3 is configured by arranging filter plates 10 in series, and the filter plates 10 are configured by stretching a filter cloth 18 so as to cover a plate-shaped base plate portion 11 having a hole portion 16 formed as a through hole in the center. The filter press device 1 shown in FIG. 9 has an approaching and separating device (detailed illustration is omitted in FIG. 9) that can approach and separate the multiple filter plates 10 constituting the filter plate structure 3, and when a solid-liquid mixture is supplied, the solid-liquid mixture (e.g., slurry such as muddy water) is pressurized and pressed into the hole portion 16 of each filter plate 10 by a pump in a stacked state in which the adjacent filter plates 10 are in close contact with each other (see FIG. 2 and FIG. 8). The pressed solid-liquid mixture accumulates in the filter chamber (filter chamber) 40 shown in FIG. 2, FIG. 8, etc. under high internal pressure, and moisture is discharged from the minute gaps in the filter cloth 18. Then, between the adjacent filter plates 10 (specifically, between the filter cloths 18 of the adjacent filter plates 10), a solid (dehydrated cake) is formed, which is the solidified residue obtained by removing a large amount of water from the solid-liquid mixture supplied from the pump. Note that, although the details of the flow path of the water passing through the meshes of the filter cloth 18 and flowing into the inside of the filter plate 10 (details of the drainage channel 28) are omitted in Figures 1 and 2, the water that has passed through the meshes of the filter cloth 18 and flowed into the inside of the filter plate 10 is actually discharged to the outside (lower part) of the filter plate 10 through the drainage channel 28 in the filter plate 10.

[0023] Next, the filter plate structure 3 will be described in detail. As shown in Fig. 1, the filter plate structure 3 is a structure composed of a plurality of filter plates 10. Each filter plate 10 has the same structure.

[0024] In the following description, a predetermined number of filter plates 10 arranged alternately are referred to as filter plate portions 8, and a plurality of filter plates 10 arranged alternately between the plurality of filter plate portions 8 are referred to as contact portions 9. In the filter plate structure 3, all filter plate portions 8 and all contact portions 9 have the same structure. Each contact portion 9 is arranged opposite to the filter plate portion 8, and is configured such that its relative position with respect to the filter plate portion 8 can be switched between a contact position in which it is in contact with the filter plate portion 8 and an open position displaced from the filter plate portion 8, and an accommodation space is configured inside. In the filter plate structure 3, when the contact portion 9 is in the contact position and in a contact state, a filter chamber is configured by the filter plate portion 8 and the contact portion 9.

[0025] Here, a description will be given of the configuration of one of the filter plate portion 8 and the contact portion 9 (the configuration of the filter plate 10). The filter plate 10 is a plate-shaped portion that becomes the filter plate portion 8 or the contact portion 9, and is mainly composed of a base plate portion 11 and a filter cloth 18.

[0026] The base plate portion 11 has an overall plate-like shape and is provided with two central recesses 12 on both sides in the thickness direction, two pressing portions 14 on both sides in the thickness direction, and a hole portion 16.

[0027] The two central recesses 12 are both recessed in the thickness direction of the substrate 11 at a central position away from the periphery of the substrate 11. In FIG. 1 and the like, of the two central recesses 12 formed on each filter plate 10, the recess on one side (the side on which the annular protrusion 24 is formed) is referred to as one central recess 12A (or simply as one central recess 12A), and the recess on the other side (the side on which the annular recess 34 is formed) is referred to as the other central recess 12B (or simply as one central recess 12B). As shown in FIG. 4, one central recess 12A is a recess with a rectangular outer diameter when viewed from the front side, and as shown in FIG. 6, the other central recess 12B is a recess with a rectangular outer diameter when viewed from the back side.

[0028] In this configuration, one central recess 12A of the filter plate 10 functioning as the filter plate portion 8 functions as the recessed portion 8A, and the other central recess 12B of the filter plate 10 functioning as the filter plate portion 8 functions as the recessed portion 8B. The recessed portions 8A and 8B are formed on both outer surface portions (specifically, both plate surface portions facing both contact portions 9) of the base plate portion 11 constituting the filter plate portion 8, respectively, and form a part of the filter chamber 40 described later. Furthermore, one central recess 12A of the filter plate 10 functioning as the contact portion 9 functions as the storage portion 9A, and the other central recess 12B of the filter plate 10 functioning as the contact portion 9 functions as the storage portion 9B. The storage portion 9A is formed in a concave shape, and when the contact portion 9 is in a contact state in which it is in contact with the filter plate portion 8 on the side facing the storage portion 9A, it forms the filter chamber 40 together with the recessed portion 8B of the filter plate portion 8. The storage portion 9B is formed in a concave shape, and when the contact portion 9 is in contact with the filter plate portion 8 on the side opposite to the storage portion 9B, the contact portion 9 forms a filter chamber 40 together with the recessed portion 8A of the filter plate portion 8.

[0029] The pressing portion 14 is a portion that is arranged in a ring shape surrounding the central recess 12. Among these, one pressing portion 14A of each filter plate 10 is a portion that faces the other pressing portion 14B of the other filter plate 10 and presses against each other. As shown in FIG. 4, the pressing portion 14A on one side (the side on which the annular protrusion 24 is formed) is a rectangular frame portion when viewed from the front side, and is arranged in a quadrangular shape (specifically, a square shape) along the peripheral portion of the filter plate 10. As shown in FIG. 6, the pressing portion 14B on the other side (the side on which the annular recess 34 is formed) is a rectangular frame portion when viewed from the front, and is arranged in a quadrangular shape (specifically, a square shape) along the peripheral portion of the filter plate 10.

[0030] The pressing portion 14 provided on the filter plate 10 functioning as the filter plate portion 8 has a pressing portion 14A on one side functioning as a first pressing portion 8C, and a pressing portion 14B on the other side functioning as a first pressing portion 8D. The first pressing portion 8C is disposed on the outer surface of one side (one of the contact portions 9 side) of the substrate portion 11 in the plate thickness direction so as to surround the recessed portion 8A, and functions to press the contact portion 9 facing the first pressing portion 8C when in a contact state. The first pressing portion 8D is disposed on the outer surface of one side (the other of the contact portions 9 side) of the substrate portion 11 in the plate thickness direction so as to surround the recessed portion 8B, and functions to press the contact portion 9 facing the first pressing portion 8D when in a contact state.

[0031] The pressing portion 14 provided on the filter plate 10 functioning as the contact portion 9 has a pressing portion 14A on one side functioning as the second pressing portion 9C, and a pressing portion 14B on the other side functioning as the second pressing portion 9D. The second pressing portion 9C is disposed on the outer surface of one side in the plate thickness direction (one filter plate portion 8 side) of the substrate portion 11 so as to surround the accommodation portion 9A, and functions to press the first pressing portion 8D of the filter plate portion 8 facing the second pressing portion 9C when in a contact state. The second pressing portion 9D is disposed on the outer surface of one side in the plate thickness direction (the other filter plate portion 8 side) of the substrate portion 11 so as to surround the accommodation portion 9B, and functions to press the first pressing portion 8C of the filter plate portion 8 facing the second pressing portion 9D when in a contact state.

[0032] As shown in Figures 4 and 7, the pressing portion 14A on one side (the side on which the annular protrusion 24 is formed) is formed with an opposing portion 22 arranged in a ring shape (specifically, in a rectangular frame shape) around the central recess 12A, and an annular protrusion 24 arranged in a ring shape (specifically, in a rectangular frame shape) around the central recess 12A and protruding from the surface of the opposing portion 22.

[0033] The annular protrusion 24 is made of an elastic material such as rubber or an elastomer other than rubber, and is fixed to the pressing part 14A by fitting into a groove (a groove formed to surround the central recess 12A) formed in the opposing part 22 of the pressing part 14A. As shown in FIG. 7, the annular protrusion 24 has a curved shape so that the outer shape of a cross section cut in a plane direction perpendicular to the direction in which the annular protrusion 24 extends is convex outward. The annular protrusion 24 is hollow with a void 24A formed inside. The void 24A is formed outside the position of the opposing part 22 in the thickness direction of the filter plate 10 (farther from the center in the thickness direction), and is configured to extend along the direction in which the annular protrusion 24 extends and is arranged in a ring shape around the central recess 12.

[0034] As shown in Figures 6 and 7, the pressing portion 14B on the other surface side (the surface side on which the annular recess 34 is formed) is formed with an opposing portion 32 arranged in a ring shape (specifically, in a rectangular frame shape) around the central recess 12B, and an annular recess 34 arranged in a ring shape (specifically, in a rectangular frame shape) around the central recess 12B and recessed from the surface of the opposing portion 32.

[0035] In this configuration, one of the opposing parts 22 of the filter plate 10 functioning as the filter plate part 8 functions as the first opposing part 8E, and the other opposing part 32 of the filter plate 10 functioning as the filter plate part 8 functions as the first opposing part 8F. Each of the first opposing parts 8E, 8F is disposed around the recessed parts 8A, 8B, respectively, and is a part whose surface faces each of the second pressing parts 9D, 9C when in a tight contact state. Similarly, one of the opposing parts 22 of the filter plate 10 functioning as the tight contact part 9 functions as the second opposing part 9E, and the other opposing part 32 of the filter plate 10 functioning as the tight contact part 9 functions as the second opposing part 9F. Each of the second opposing parts 9E, 9F is disposed around the storage parts 9A, 9B, respectively, and is a part whose surface faces each of the first pressing parts 8D, 8C when in a tight contact state.

[0036] As shown in FIG. 1, in each filter plate 10, a hole 16 is formed so as to penetrate between a central recess 12A on one side (the side on which the annular convex portion 24 is formed) and a central recess 12B on the other side (the side on which the annular concave portion 34 is formed) in the plate thickness direction. The hole 16 functions as a flow path for flowing a solid-liquid mixture in the thickness direction of the filter plate 10 so as to pass through the inside of the filter plate 10. The hole 16 of the filter plate 10 functioning as the filter plate portion 8 is a flow path that passes through the inside of the base plate portion 11 and continues to the recess portions 8A and 8B. Similarly, the hole 16 of the filter plate 10 functioning as the contact portion 9 is a flow path that passes through the inside of the base plate portion 11 and continues to the storage portions 9A and 9B.

[0037] As shown in Fig. 1 and Fig. 3, the filter cloth 18 is arranged so as to cover the outer area of ​​the hole 16 on one surface side in the plate thickness direction, and as shown in Fig. 1 and Fig. 5, the filter cloth 18 is arranged so as to cover the outer area of ​​the hole 16 on the other surface side in the plate thickness direction. Note that in Fig. 2 and Fig. 8, two filter cloths 18 interposed between the opposing portion 22 and the opposing portion 32 and between the annular convex portion 24 and the annular concave portion 34 are omitted. In Fig. 1 to Fig. 8, the filter cloth 18 covering one surface side (the surface side on which the annular convex portion 24 is formed) is referred to as filter cloth 18A, and the filter cloth 18 covering the other surface side (the surface side on which the annular concave portion 34 is formed) is referred to as filter cloth 18B.

[0038] As shown in FIG. 3, the filter cloth 18A on one side (the side on which the annular convex portion 24 is formed) is fixed to the annular plate portion 15A described later, and is entirely disposed in the outer region of the annular plate portion 15A up to the peripheral portion of the base portion 11. As shown in FIG. 5, the filter cloth 18B on the other side (the side on which the annular concave portion 34 is formed) is fixed to the annular plate portion 15B described later, and is entirely disposed in the outer region of the annular plate portion 15B up to the peripheral portion of the base portion 11. In FIG. 1, FIG. 2, FIG. 7, FIG. 8, etc., the filter cloth 18 is conceptually shown by a two-dot chain line, and in FIG. 3 and FIG. 5, the filter cloth 18 is conceptually shown as a patterned region. In the example of FIG. 2 and FIG. 8, the filter cloths 18A and 18B are also present in the portion sandwiched between the pressing portions 14A and 14B, but the illustration (illustration of the two-dot chain line) of the filter cloths 18A and 18B in this portion is omitted. In the example of Fig. 1 etc., the peripheral portion of the filter cloth 18A and the peripheral portion of the filter cloth 18B are connected in each filter plate 10, but the peripheral portions may not be connected. The filter cloth 18A only needs to be arranged so as to cover the inner surface of the central recess 12A at least in the area outside the hole 16, and the covering area of ​​the filter cloth 18A is not limited to the configuration of Fig. 1, Fig. 3 etc.

[0039] In this configuration, the filter cloth 18 arranged on the filter plate 10 functioning as the filter plate portion 8 is arranged to cover the inner surfaces of the recessed portions 8A and 8B and to cover the surfaces of the first pressing portions 8C and 8D, with the filter cloth 18A on one side being arranged across the recessed portion 8A and the first pressing portion 8C, and the filter cloth 18B on the other side being arranged across the recessed portion 8B and the first pressing portion 8D. The filter cloth 18 arranged on the filter plate 10 functioning as the contact portion 9 is arranged to cover the inner surfaces of the storage portions 9A and 9B and to cover the surfaces of the second pressing portions 9C and 9D, with the filter cloth 18A on one side being arranged across the storage portion 9A and the second pressing portion 9C, and the filter cloth 18B on the other side being arranged across the storage portion 9B and the second pressing portion 9D.

[0040] In the above configuration, the annular protrusion 24 provided on the first pressing portion 8C functions as the first seal portion 8G, is disposed around the recessed portion 8A, and is protruding from the surface of the first opposing portion 8E. The annular recess 34 provided on the first pressing portion 8D functions as the first seal portion 8H, is disposed around the recessed portion 8B, and is recessed from the surface of the first opposing portion 8F.

[0041] The annular convex portion 24 provided on the second pressing portion 9C functions as the second seal portion 9G. The second seal portion 9G is disposed around the accommodating portion 9A, convex from the surface of the second opposing portion 9E, and presses against the first seal portion 8H when in a tight contact state. The annular concave portion 34 provided on the second pressing portion 9D functions as the second seal portion 9H. The second seal portion 9H is disposed around the accommodating portion 9B, concave from the surface of the second opposing portion 9F, and presses against the first seal portion 8G when in a tight contact state.

[0042] The filter plate structure 3 shown in Fig. 1 etc. can be switched between a state in which adjacent filter plates 10 are spaced apart as shown in Fig. 1 and Fig. 7, and a state in which adjacent filter plates 10 are in close contact as shown in Fig. 2 and Fig. 8. The multiple filter plates 10 are aligned in the thickness direction as shown in Fig. 1 by rails not shown in Fig. 1 etc. (i.e., the thickness directions of the filter plates 10 are aligned in the same direction) and the positions of the outer peripheries of the filter plates 10 (the positions of the outer peripheries in a planar direction perpendicular to the thickness direction) are aligned, so that adjacent filter plates of the multiple filter plates 10 can move closer to and away from each other by moving along the rails in this aligned state.

[0043] 2 and 8, when a plurality of filter plates 10 are stacked so that one filter plate 10 and another filter plate 10 are in close contact with each other, the annular convex portion 24 of the first filter plate 10 enters the annular concave portion 34 of the other filter plate 10 and presses the inner surface of the annular concave portion 34, and the opposing portion 22 of the first filter plate 10 and the opposing portion 32 of the other filter plate 10 press against each other. In the example of Fig. 8, two filter cloths 18A, 18B that cover the two filter plates 10, respectively, are interposed between the opposing portion 22 of the first filter plate 10 and the opposing portion 32 of the other filter plate 10, and in this state, the opposing portion 22 of the first filter plate 10 and the opposing portion 32 of the other filter plate 10 press against each other. That is, the opposing portion 22 of the first filter plate 10 and the opposing portion 32 of the second filter plate 10 press against each other via the filter cloth 18A of the first filter plate 10 and the filter cloth 18B of the second filter plate 10. The two filter cloths 18A and 18B covering the two filter plates 10 are also interposed between the annular convex portion 24 and the annular concave portion 34, and in this state (i.e., the filter cloths 18A and 18B are interposed between the outer surface of the annular convex portion 24 and the inner surface of the annular concave portion 34), the annular convex portion 24 and the annular concave portion 34 press against each other. That is, the annular convex portion 24 of the first filter plate 10 presses against the inner surface of the annular concave portion 34 via the filter cloth 18A of the first filter plate 10 and the filter cloth 18B of the second filter plate 10.

[0044] In the stacked state in which the adjacent filter plates 10 are in close contact with each other as shown in FIG. 8, if a solid-liquid mixture is poured through the hole 16 by a first injection device 60 (for example, a slurry supply device including a pump) shown in FIG. 15, the pressed solid-liquid mixture accumulates in the filter chamber (filter chamber) 40 shown in FIG. 2, FIG. 8, etc. under high internal pressure (see also FIG. 15), and moisture is discharged to the substrate portion 11 side (i.e., the back side of the filter cloth 18) through a small gap in the filter cloth 18. Then, a dehydrated cake is formed between the adjacent filter plates 10 (specifically, between the filter cloths of the adjacent filter plates 10). The dehydrated cake is an object in which a certain amount of moisture has been removed from the solid-liquid mixture 7 injected into the filter chamber 40 as shown in FIG. 2.

[0045] In this configuration, a base plate 11 is provided in each filter plate 10, and the base plate 11 is configured in a plate shape, and one of the two center recesses 12, a center recess 12A, and one of the two pressing portions 14, a pressing portion 14A, are formed on one plate surface side (the above-mentioned one surface side), and the other of the two center recesses 12, a center recess 12B, and the other of the two pressing portions 14, a pressing portion 14B, are formed on the other plate surface side (the above-mentioned other surface side). A filter cloth 18A is provided to cover the inner wall portion of one center recess 12A, and a filter cloth 18B is provided to cover the inner wall portion of the other center recess 12B. A drainage channel 28 (one drainage channel 28A and the other drainage channel 28B) leading to the outside of the filter plate 10 is provided on the back side of the filter cloth 18 in one center recess 12A and the other center recess 12B.

[0046] In each of the central recess 12A on one side and the central recess 12B on the other side of the filter plate 10, a drain plate 13 (one drain plate 13A and the other drain plate 13B) having a water passage part that passes liquid in the plate thickness direction is provided on the inner wall part (inner surface part) on the deepest side of each in the depth direction. The water passage parts of both the drain plates 13A and 13B may be composed of a number of holes, or may be composed of grooves or notches. The drain plates 13A and 13B may be configured so that water can pass from the front side to the back side while supporting the filter cloth 18 on the front side, and may be configured such that a number of through holes are formed in a plate-like body, or may be configured in a net-like manner. In the base plate portion 11, a plate-like body 11A is provided on the inside of each drain plate 13 in the plate thickness direction (plate thickness direction of the filter plate 10), and both sides in the plate thickness direction are covered by each drain plate 13. As shown in Figs. 1 and 4, one pressing part 14A is a rectangular frame body fixed along the peripheral part of the plate-like body 11A on one side of the plate-like body 11A. The other pressing part 14B is a rectangular frame body fixed along the peripheral part of the plate-like body 11A on the other side of the plate-like body 11A. One drain plate 13A is fixed in a state in which its peripheral part is sandwiched between the plate-like body 11A and the inner edge part of the frame body constituting the pressing part 14A. One drain plate 13B is fixed in a state in which its peripheral part is sandwiched between the plate-like body 11A and the inner edge part of the frame body constituting the pressing part 14B.

[0047] Between each of the drainage plates 13 (one drainage plate 13A and the other drainage plate 13B) and the plate-like body 11A, drainage channels 28A and 28B are respectively formed, which lead to the outside of the filter plate 10. Both of the drainage channels 28A and 28B are formed as water passages that allow water to pass through.

[0048] The drainage channels 28A formed on the back side of the filter cloth 18A in one of the central recesses 12A are, for example, as shown in Figs. 10 to 12. In the example of Figs. 10 to 12, a plurality of drainage channels 28A are formed in a groove shape at the lower end side (vertical lower end side when installed) of one side of the base plate 11, and water can flow through each of the drainage channels 28A. One end (upper end) of each of the drainage channels 28A is located on the back side of the drainage plate 13A, and a part of the back surface of the drainage plate 13A faces the internal space of each of the drainage channels 28A. The other end (lower end) of each of the drainage channels 28A reaches the lower end of the filter plate 10, and the internal space of each of the drainage channels 28A communicates with the space outside the filter plate 10. Furthermore, it is desirable that there be a space between the back surface of the drainage plate 13A and the front surface of the plate-shaped body 11A, and that this space be connected to each of the drainage channels 28A.If configured in this manner, moisture that has flowed into the back surface of the drainage plate 13A will easily flow to the outside of the filter plate 10 via each of the drainage channels 28A.

[0049] The drainage channels 28B formed on the back side of the filter cloth 18B in one of the central recesses 12B are, for example, as shown in Figs. 10, 13, and 14. In the examples of Figs. 10, 13, and 14, a plurality of drainage channels 28B are formed in a groove shape at the lower end side (vertical lower end side when installed) of one side of the base plate 11, and water can flow through each of the drainage channels 28B. One end (upper end) of each of the drainage channels 28B is located on the back side of the drainage plate 13B, and a part of the back surface of the drainage plate 13B faces the internal space of each of the drainage channels 28B. The other end (lower end) of each of the drainage channels 28B reaches the lower end of the filter plate 10, and the internal space of each of the drainage channels 28B communicates with the space outside the filter plate 10. Furthermore, it is desirable that a space exists between the back surface of the drainage plate 13B and the front surface of the plate-shaped body 11B, and that this space is connected to each of the drainage channels 28B.If configured in this manner, moisture that flows into the back surface of the drainage plate 13B will easily flow to the outside of the filter plate 10 via each of the drainage channels 28B.

[0050] In the examples of Figures 10 to 15, a configuration is illustrated in which multiple drainage channels 28 are provided on the lower end side of the filter plate 10, but any flow path can be used as long as it can discharge water that has flowed through the filter cloth 18 into the drainage plate 13 to the outside of the filter plate 10.

[0051] As shown in Figs. 1, 2, 3, and 5, the filter plate 10 has a pair of annular plate parts 15A and 15B fixed in one central recess 12A and the other central recess 12B of the base plate part 11, respectively. The annular plate parts 15A and 15B are formed with through hole side protrusions 17A and 17B protruding in the plate thickness direction of the filter plate 10. A plurality of through hole side protrusions 17A protrude from the annular plate part 15A on one side, and the plurality of through hole side protrusions 17A are arranged so as to surround the hole part 16 around the hole part 16 as shown in Fig. 11. Similarly, a plurality of through hole side protrusions 17B protrude from the annular plate part 15B on the other side, and the plurality of through hole side protrusions 17B are arranged so as to surround the hole part 16 around the hole part 16 as shown in Fig. 13. The hole 16 is formed in a configuration that communicates from one annular plate portion 15A of the pair of annular plate portions 15A, 15B to the other annular plate portion 15B, and specifically, the inside of a cylindrical portion that connects the pair of annular plate portions 15A, 15B is the hole 16. In this configuration, as shown in Fig. 2, when one surface side of one filter plate 10 and the other surface side of the other filter plate 10 are overlapped so as to be pressed against each other, the through hole side protrusion 17A on one surface side of one filter plate 10 and the through hole side protrusion 17B on the other surface side of the other filter plate 10 face each other. When the through-hole side projection 17A on one side of one filter plate 10 and the through-hole side projection 17B on the other side of the other filter plate 10 face each other as shown in Fig. 2, the distance (distance between the tips) between these through-hole side projections 17A, 17B is smaller than the plate surface distance between the annular plate parts 15A, 15B, and may be 0 (i.e., the opposing through-hole side projections 17A, 17B may be in contact). Note that in the example of Fig. 2, the filter cloth 18 is not interposed between the opposing through-hole side projections 17A, 17B.

[0052] In one central recess 12A and the other central recess 12B, a drainage plate side protrusion 19 (one drainage plate side protrusion 19A and the other drainage plate side protrusion 19B) protruding in the plate thickness direction from each drainage plate 13 is formed. One drainage plate side protrusion 19A is fixed to at least one of the drainage plate 13A or the plate-like body 11A, and is configured to protrude in the plate thickness direction (plate thickness direction of the filter plate 10) from the surface of the drainage plate 13A. The drainage plate side protrusion 19A has a tapered shape that becomes thinner as it approaches the tip side in the protruding direction. In the example of FIG. 4, a plurality of drainage plate side protrusions 19A having such a configuration are arranged to surround the hole portion 16. The other drainage plate side protrusion 19B is fixed to at least one of the drainage plate 13B or the plate-like body 11A, and is configured to protrude in the plate thickness direction (plate thickness direction of the filter plate 10) from the surface of the drainage plate 13B. The drainage plate side protrusion 19B has a tapered shape that becomes thinner as it approaches the tip side in the protruding direction. In the example of FIG. 6, a plurality of drainage plate side protrusions 19B having such a configuration are arranged to surround the hole 16. Then, when one side of the first filter plate 10 and the other side of the other filter plate 10 are stacked so as to press against each other as shown in FIG. 2, each of the drainage plate side protrusions 19A on one side of the first filter plate 10 and each of the drainage plate side protrusions 19B on the other side of the other filter plate 10 face each other. When the drainage plate side protrusions 19A on one side of the first filter plate 10 and the drainage plate side protrusions 19B on the other side of the other filter plate 10 face each other as shown in FIG. 2, the distance (the distance between the tips) between these drainage plate side protrusions 19A, 19B is smaller than the distance between the drainage plates 13A, 3B facing each other. In the example of FIG. 2 etc., the filter cloths 18A, 18B are interposed between the opposing drainage plate side protrusions 19A, 19B, and the filter cloths 18A, 18B are sandwiched between the opposing drainage plate side protrusions 19A, 19B.

[0053] The filter press device 1 shown in Figure 9 has such a filter plate structure 3, and specifically, as shown in Figures 15 and 16, the multiple filter plates 10 that constitute the filter plate structure 3 are aligned in a predetermined posture (i.e., a posture in which the thickness direction of each filter plate 10 is in the same direction and the positions of the outer edges of each filter plate 10 are aligned), and the multiple filter plates 10 can be moved along guide rails 90 (guide rails 90A, 90B), and this moving action allows adjacent filter plates among the multiple filter plates 10 to move towards and away from each other.

[0054] Although not shown in Figures 1 to 14, as shown in Figures 16 and 17, each filter plate 10 is provided with a pair of protruding parts 41, 42 that protrude laterally from both the left and right sides of the base plate part 11 of each filter plate 10. The pair of protruding parts 41, 42 function as a pair of supported parts, and are supported while being placed on the guide rails 90A, 90B. By moving the pair of protruding parts 41, 42 while being placed on the guide rails 90A, 90B, each filter plate 10 moves in a predetermined direction (the plate thickness direction of each filter plate 10) while maintaining a predetermined posture.

[0055] In addition to the above-mentioned filter plate structure 3, the filter press apparatus 1 includes a holding device 50, a first injection device 60 (hereinafter also referred to as a slurry supply device), a second injection device 70 (hereinafter also referred to as an air supply device), a supply path 62 for supplying a solid-liquid mixture 7, a supply path 72 for supplying air, a first switching unit 81 for switching between opening and blocking the supply path 62, and a second switching unit 82 for switching between opening and blocking the supply path 72. Although not shown in Figs. 1 to 17, the filter press apparatus 1 is also provided with a control device 112 (e.g., an information processing device such as a computer) that controls the operations (operation timing, control amount, etc.) of the holding device 50, the first injection device 60, the second injection device 70, the first switching unit 81, and the second switching unit 82 as shown in Fig. 19. The control device 112 may be configured by a single device or may be configured by multiple devices.

[0056] The holding device 50 comprises a pair of guide rails 90 (guide rails 90A, 90B), a drive unit 54, and fixed walls 51, 52, which are integrally assembled. The drive unit 54 comprises an action unit 54C that acts on the filter plate 10 at the end (the end on the fixed wall 52 side) of the filter plate group 5, a drive shaft 54B that is connected to the action unit 54C, and a drive unit 54A that moves the drive shaft 54B in a predetermined direction (the plate thickness direction of each filter plate 10 of the filter plate group 5). The drive unit 54A moves the action unit 54C toward the fixed wall 51 via the drive shaft 54B, so that the multiple filter plates 10 are pressed toward the fixed wall 51 while maintaining a predetermined posture, and the adjacent filter plates in the filter plate group 5 are in contact with each other as shown in Figures 15 and 16. On the other hand, the driving unit 54A moves the action unit 54C toward the fixed wall 52 via the driving shaft 54B, so that the adjacent filter plates in the filter plate group 5 are spaced apart from each other. For example, if a spacing regulation unit (not shown) is provided to regulate the maximum spacing between adjacent filter plates 10 to a predetermined spacing, when the action unit 54C engages or holds the filter plate 10 at the end (the end on the fixed wall 52 side) of the filter plate group 5 and operates to move the filter plate 10 toward the fixed wall 52, the filter plates move so that the adjacent filter plates are spaced apart from each other. Note that the example shown here is merely one example, and the holding device may have another configuration as long as it is configured to move the multiple filter plates 10 close to each other and apart from each other while aligning them in a predetermined position (i.e., a position in which the thickness direction of each filter plate 10 is the same direction and the positions of the outer peripheries of each filter plate 10 are aligned).

[0057] In this way, by moving the acting portion 54C toward the fixed wall 51, the holding device 50 can arrange multiple filter plates 10 in a stacked state as shown in Figures 15 and 16, and hold them in a holding state (first holding state) in which the annular convex portion 24 of one filter plate 10 enters into the annular recess 34 of the other filter plate 10 between adjacent filter plates, pressing against the inside of the annular recess 34, and the opposing portion 22 of one filter plate 10 and the opposing portion 32 of the other filter plate 10 press against each other (see Figures 2 and 8 for the specific state between adjacent filter plates).

[0058] The first injection device 60 is a transfer device that transfers a solid-liquid mixture from a solid-liquid mixture storage unit (e.g., a slurry storage tank, etc.) not shown to the filter plate group 5 side, and can inject a solid-liquid mixture into the filter plate group 5 through the supply path 62 when the first switching unit 81 is in an open state and the supply path 62 is in communication with the hole 16 at the end of the filter plate group 5. Specifically, the first injection device 60 is configured to inject the solid-liquid mixture 7 into the inside of the filter plates 10 through the hole 16 of the filter plate 10 at one end of the filter plate group 5 when the filter plate group 5 consisting of the filter plates 10 is held in the first holding state by the holding device 50 as shown in Figures 15 and 16. The first switching unit 81 is a device that switches between a first stop state that stops the inflow and outflow of fluid at one end side of the filter plate group 5, and a first release state that releases the first stop state, and is configured with a known solenoid valve that switches the supply path 62 (pipe) between an open state and a blocked state, and the opening and blocking of the first switching unit 81 is controlled by a control device 112 (Figure 19).

[0059] The second injection device 70 is configured as a known air supply device capable of pumping air, and can inject air into the filter plate group 5 through the supply path 72 when the second switching unit 82 is in an open state and the supply path 72 is connected to the hole 16 at the end of the filter plate group 5. Specifically, when the filter plate group 5 consisting of the plurality of filter plates 10 is held in the first holding state by the holding device 50 as shown in Figs. 15 and 16, the second injection device 70 injects air into the plurality of filter plates 10 through the hole 16 at the other end opposite to the one end of the filter plate group 5. The second switching unit 82 is a device that switches between a second stopped state that stops the flow of fluid in and out of the other end of the filter plate group 5, and a second released state that releases the second stopped state, and is configured with a known solenoid valve that switches the supply path 72 (pipe) between an open state and a blocked state, and the opening and blocking of the second switching unit 82 is controlled by the control device 112 (Figure 19).

[0060] In the filter press apparatus 1, when the holding device 50 is held in the first holding state as shown in FIG. 16, the first injection device 60 injects the solid-liquid mixture 7 into the inside of the filter plate group 5 with the second switching unit 82 switched to the second stop state (state in which the supply path 72 is blocked) and the first switching unit 81 switched to the first release state (state in which the supply path 62 is opened). After the first injection device 60 injects the solid-liquid mixture 7, when the holding device 50 is held in the first holding state as shown in Figures 15 and 16, the second injection device 70 injects air into the filter plate group 5 with the first switching unit 81 switched to the first stop state (state in which the supply path 62 is blocked) and the second switching unit 82 switched to the second open state (state in which the supply path 72 is opened), causing air to flow from the hole 16 at the other end to the drainage path 28 of each filter plate 10, and discharging the liquid (moisture) of the solid-liquid mixture 7 present inside the filter plate group 5 together with the air to the outside of the filter plate group 5 via the drainage path 28. The operation timing and operation time of each device are controlled by the control device 112 (Figure 19).

[0061] As shown in Fig. 19, the filter press apparatus 1 is provided with various detection units. Fig. 19 illustrates four of the detection units 114A to 114D. The detection units 114A to 114D may be sensors that detect physical quantities such as temperature (e.g., air temperature, water temperature, etc.), flow rate, voltage, current, power, and pressure (e.g., air pressure, water pressure, etc.), or may be sensors that detect the presence or proximity of an object, or may be other detection units. The detection units may have a function of determining whether or not an abnormality exists at a predetermined position of the filter press apparatus 1 (for example, a function of determining whether or not the temperature at a predetermined position is equal to or higher than a predetermined value, a function of determining whether or not the water pressure at a predetermined position is equal to or higher than a predetermined value, etc.).

[0062] 3. Main parts of the management system 100 18 is a system that manages a treatment system 110 that includes a filter press apparatus 1. The treatment system 110 may be a "treatment system that treats at least one of soil and a solid-liquid mixture" other than a treatment system that includes the filter press apparatus 1. In a representative example that will be described in detail below, the treatment system 110 is a system that includes the filter press apparatus 1.

[0063] The management system 100 is a system that manages the processing system 110. The "management" performed by the management system 100 includes information acquisition management for acquiring various information (e.g., physical quantities such as temperature, flow rate, voltage, current, power, pressure, etc., and detection results such as the presence and proximity of an object) that are detection results of detection units (e.g., detection units 114A to 114D) provided in the processing system 110, and abnormality management for determining whether or not an abnormality has occurred in the processing system 110.

[0064] The management system 100 includes a management device 104 and an information terminal 190. The management device 104 has a control unit, a storage unit, a communication unit, a display unit, and the like. The control unit included in the management device 104 includes an information processing device such as a CPU, and has an information processing function for performing various controls and calculations. The storage unit included in the management device 104 has a storage medium such as a ROM, a RAM, a HDD, and an SSD, and can store various information. The communication unit included in the management device 104 is a device that communicates with the processing system 110 and the information terminal 190. The communication unit may have a function of performing wired communication, or may have a function of performing wireless communication. The communication unit has a function of performing wired or wireless communication with a relay device such as an access point or a router, or other external device, and communicates with the processing system 110 and the information terminal 190 via the relay device or the external device.

[0065] The information terminal 190 is a smartphone, a tablet terminal, a notebook computer, or another portable information processing terminal. The information terminal 190 includes a control unit 192, a display unit 193, a storage unit 194, an operation unit 195, a communication unit 196, and the like.

[0066] In this embodiment, the control unit and communication unit of the management device 104 correspond to an example of an information acquisition unit, which communicates with the processing system 110 directly or via another device, and acquires information based on the detection results of the detection units provided in the processing system 110. The information based on the detection results of the detection units may be a physical quantity (e.g., physical quantities such as temperature, flow rate, voltage, current, power, and pressure) detected by any of the detection units 114A to 114D, a detection result such as the presence or proximity of an object detected by any of the detection units 114A to 114D, or a result of determining whether or not an abnormality has occurred in the processing system 110.

[0067] In the management system 100, a display unit (such as a display device capable of displaying information such as letters and numbers, or images) or an audio output unit (such as a speaker) provided in the management device 104 may function as the notification unit, or the information terminal 190 (specifically, the control unit 192 and the display unit 193 provided in the information terminal 190) may function as the notification unit. In either case, the notification unit issues a notification at a base or a portable information processing terminal away from the processing system 110 based on the information acquired by the information acquisition unit. The notification issued by the notification unit may be a notification of a physical quantity (such as a temperature, a flow rate, a voltage, a current, a power, a pressure, or other physical quantity) detected by any of the detection units 114A to 114D, a notification of a detection result such as the presence or proximity of an object detected by any of the detection units 114A to 114D, or a notification of a result of determining whether or not an abnormality has occurred in the processing system 110.

[0068] As an example of the notification unit "notifying the result of judging whether or not an abnormality occurs in the treatment system 110", for example, the treatment system 110 may transmit an abnormality signal to the management device 104 when the detection results of the detection units 114A to 114D satisfy an abnormality condition. In this case, the information acquisition unit may receive the abnormality signal when the treatment system 110 transmits the abnormality signal, and the notification unit may notify the abnormality when the information acquisition unit receives the abnormality signal. For example, when the detection unit 114A of the treatment system 110 is a sensor that detects the water pressure of the solid-liquid mixture, the treatment system 110 may transmit an abnormality signal to the management device 104 in a remote location when the water pressure detected by the detection unit 114A exceeds a threshold value. In this case, an abnormality may be reported on the display unit of the management device 104 (for example, a report that the water pressure of the solid-liquid mixture is an abnormal value), or information that the water pressure of the solid-liquid mixture is an abnormal value may be transmitted to the information terminal 190, and the abnormality may be reported on the information terminal 190.

[0069] The abnormal condition is not limited to the above example, and various examples are possible. For example, the abnormal condition may be satisfied when "an abnormality occurs in which a solid-liquid mixture is sprayed out from between the filter plates while the solid-liquid mixture is being supplied into the filter chamber in the filter press device." Alternatively, the abnormal condition may be satisfied when "the pressure at a predetermined position in the filter press device is out of the normal range." Alternatively, the abnormal condition may be satisfied when "the plate opener provided in the filter press device does not operate normally." Examples of abnormalities other than these abnormal conditions include system abnormalities (process abnormalities), gutter abnormalities, compressor abnormalities, and abnormalities in the presence or absence of a solid-liquid mixture.

[0070] The notification by the notification unit may be a notification that provides image information such as still images and videos. Specifically, a camera that monitors a predetermined position of the filter press device may be provided, and the still images and videos captured by the camera may be displayed on a base or a portable information processing terminal away from the processing system to provide the notification.
