DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0009] Hereinafter, the first embodiment will be described with reference to the drawings.

[0010] 1 shows the overall configuration of a water circulation system 12 according to the technology of the present disclosure. This water circulation system 12 is a system that circulates and purifies wastewater used in the home, for example, so that the wastewater can be reused in the home. Examples of wastewater include water used in water usage points 14 in the home, such as a bathroom, a flushing toilet seat, a toilet, etc.

[0011] The water circulation system 12 has a wastewater tank 100 , a biological treatment tank 300 , and a treated water tank 400 .

[0012] The wastewater passes through a wastewater tank 100, a biological treatment tank 300, and a treatment tank 400 in this order, and is then circulated to a water usage point 14 (such as a washroom, a bath, or a toilet seat with a flushing function).

[0013] The water usage points 14 and the drainage tank 100 are connected by drainage piping 102. Wastewater generated at the water usage points 14 is sent to the drainage tank 100 through the drainage piping 102.

[0014] In the drainage tank 100, predetermined treatment such as stirring is performed on the drainage water. The gas in the drainage tank 100 may be discharged to the outside of the drainage tank 100, for example, by driving a fan.

[0015] The drainage tank 100 and the biological treatment tank 300 are connected by a drainage pipe 302. The drainage in the drainage tank 100 is sent to the biological treatment tank 300 through the drainage pipe 302 by driving a drainage pump 110.

[0016] A filtration device, for example, is provided inside the biological treatment tank 300. The filtration device can filter the wastewater. The gas inside the biological treatment tank 300 may be discharged to the outside of the biological treatment tank 300 by, for example, driving a fan.

[0017] The biological treatment tank 300 and the treated water tank 400 are connected by a treated water pipe 402. A treated water pump 406 is provided on the treated water pipe 402. When the treated water pump 406 is driven, wastewater from the biological treatment tank 300 is sent to the treated water tank 400.

[0018] A predetermined treatment is also performed on the wastewater in the treatment water tank 400. The gas in the treatment water tank 400 may be discharged to the outside of the treatment water tank 400, for example, by driving a fan.

[0019] The treated water tank 400 and each of the water usage points 14 are connected by a supply pipe 716. A supply pump 724 is provided on the supply pipe 716. The treated water in the treated water tank 400 is sent to each of the water usage points 14 through the supply pipe 716 by driving the supply pump 724. Note that in practice, the supply pipe 716 may branch out toward each of the water usage points 14.

[0020] Fig. 2 shows a liquid treatment device 16 including a fluid tank according to the technique of the present disclosure. The example shown in Fig. 2 is shown as one example of the liquid treatment device 16 incorporated in the water circulation system 12 shown in Fig. 1.

[0021] The liquid treatment device 16 has a rectangular parallelepiped housing 18. In the following, the width direction, depth direction, and height direction of the housing 18 are indicated by arrows W, D, and H, respectively.

[0022] Various devices for operating the liquid treatment device 16, a wastewater tank 100, a biological treatment tank 300, and a treated water tank 400 are arranged inside the housing 18. The wastewater tank 100, the biological treatment tank 300, and the treated water tank 400 are all examples of fluid tanks according to the disclosed technology, and may be collectively referred to as fluid tanks below.

[0023] 3, the fluid tank has, for example, a rectangular parallelepiped fluid tank body 20. An upper portion of the fluid tank body 20 is a rectangular opening 28 in a plan view (as viewed in the direction of arrow A1). A lid member 30 is attached to the opening 28.

[0024] 3 to 5, a partition member 32 is disposed inside the fluid tank main body 20. The partition member 32 has a partition plate and a holding member .

[0025] The partition plate 34 has a partition frame 38 and a partition plate body 40. The partition plate body 40 is formed in a plate shape, and is disposed in the fluid tank body 20 with its normal direction coinciding with the width direction (direction of arrow W) of the housing 18. The partition member 32 divides the inside of the fluid tank body 20 into two regions in the width direction (a first region 312 and a second region 314).

[0026] The partition frame 38 is a frame-shaped member to which the outer edge portions (upper edge, lower edge, and a pair of side edges) of the partition plate body 40 are attached. The partition plate body 40 is attached to the partition frame 38 with bolts 42 (see Figures 4 and 5), but the partition frame 38 and the partition plate body 40 may be integrally formed as a single member.

[0027] 3 and 4, a through hole 58 is formed in the partition plate body 40. This through hole 58 allows the flow of fluid between the first region 312 and the second region 314.

[0028] The shape, size, position, etc. of the through hole 58 can be determined based on conditions such as the type of fluid contained in the fluid tank body 20 and how the fluid is circulated within the fluid tank body 20.

[0029] 3, the through holes 58 are circular, and a plurality of through holes 58 are formed over the entire surface of the partition body 40, from the upper side to the lower side and from one end side to the other end side in the width direction of the partition body 40 (depth direction of the fluid tank body 20). By forming the through holes 58 over the entire surface of the partition body 40 in this manner, fluid can move over the entire surface of the partition body 40.

[0030] The plurality of through holes 58 do not all need to have the same shape, and for example, through holes 58 with small diameters and through holes 58 with large diameters may be mixed. In the partition plate body 40, the hole diameters of the through holes 58 may be different between the upper and lower parts, or the hole diameter may change continuously or in stages from the upper part to the lower part. Furthermore, in the partition plate body 40, the arrangement density of the through holes 58 does not need to be uniform, and for example, the arrangement density of the through holes 58 may change continuously or in stages between the upper and lower parts of the partition plate body 40.

[0031] 6. The through holes 60 are formed at the upper and lower parts of the partition body 40 with a predetermined height and width (the opening length in the depth direction of the housing 18). By forming the through holes 60 at the upper and lower parts of the partition body 40, fluid flows in opposite directions can be generated in the respective through holes 60, and circulation of drainage water can be generated between the first area 312 and the second area 314.

[0032] The opening cross-sectional area of ​​the through holes can be set according to the amount of fluid moving between the first region 312 and the second region 314. For example, by setting the total opening cross-sectional area of ​​the multiple through holes to be large, the fluid can move more easily between the first region 312 and the second region 314. In addition, by reducing the opening cross-sectional area of ​​each through hole, the movement of foreign matter in the fluid when the fluid moves from the first region 312 to the second region 314 can be suppressed. The opening cross-sectional area of ​​the through holes may change continuously or stepwise from the upper portion to the lower portion of the partition plate body 40.

[0033] In configurations having a large number of through-holes 58 , the distribution and placement density of the through-holes 58 can also be set according to the amount of fluid moving between the first region 312 and the second region 314 .

[0034] The holding member 36 has a rail 48 and a bolt 44. The rail 48 is a long plate-like member extending in the width direction of the housing 18. In the example shown in Figs. 4 and 5, the holding members 36 are provided in pairs on the front and rear sides at the upper part inside the fluid tank body 20. The longitudinal direction of the holding members 36 coincides with the width direction (direction of arrow W) of the housing 18. The rail 48 is supported by a bracket 56 provided on the inner surface of the fluid tank body 20.

[0035] The rail 48 has a plurality of bolt holes 50 spaced apart in the longitudinal direction. Also, an attachment piece 52 is formed in the upper part of the partition frame 38. An attachment hole 54 is formed in the attachment piece 52 for attaching the partition frame 38 to the holding member 36 with a bolt 44. The partition frame 38 can be attached to the rail 48 with the bolt 44 by aligning the bolt hole 50 of the rail 48 with the attachment hole 54 of the attachment piece 52. Since the rail 48 has a plurality of attachment holes 54 spaced apart in the longitudinal direction, the partition frame 38 can be attached to the rail 48 by using any one of the plurality of attachment holes 54 at any position.

[0036] 5, the fluid tank body 20 is provided with an inlet portion 46A1 and an outlet portion 46A2. The inlet portion 46A1 is set at the position of the first area 312, and the outlet portion 46A2 is set at the position of the second area 314. In other words, the partition member 32 is located between the inlet portion 46A1 and the outlet portion 46A2, and divides the fluid tank body 20 into the first area 312 and the second area 314.

[0037] Next, the operation of this embodiment will be described.

[0038] A partition member 32 is provided inside the fluid tank body 20. The partition member 32 is located between the inflow section 45A1 and the outflow section 46A2. By dividing the inside of the fluid tank body 20 using one partition member 32, it is possible to form two regions with different environments, a first region 312 and a second region 314. For example, the first region 312 and the second region 314 can be set to have different organic matter concentrations or different oxygen concentrations.

[0039] A fluid flows into the first region 312 in the fluid tank body 20 from the inlet portion 46A1. In the fluid tank body 20, for example, the fluid is processed while circulating between the first region 312 and the second region 314. The processed fluid is discharged from the second region 314 through the outlet portion 46A2.

[0040] The inside of the fluid tank body 20 is divided into a first area 312 and a second area 314 by a partition member 32. The fluid that has flowed into the first area 312 is prevented from flowing into the second area 314 all at once, i.e., a short-circuit flow is prevented.

[0041] The partition member 32 has a partition plate 34 and a holding member 36. A rail 48 of the holding member 36 has a plurality of bolt holes 50 formed therein, and the partition plate 34 can be attached to the rail 48 at any position of the bolt holes 50. That is, in this embodiment, it is possible to change the volumes of the two regions (the first region 312 and the second region 314) partitioned by the partition plate 34 in the fluid tank body 20. For example, it is possible to adopt a configuration in which the volume of the first region 312 is secured to be large in advance in consideration of a case in which a large amount of fluid flows in from the inflow portion 45A1, or conversely, it is possible to adopt a configuration in which the volume of the first region 312 is secured to be small in advance in consideration of a case in which a small amount of wastewater flows in from the inflow portion 45A1.

[0042] The holding member 36 has rails 48. The partition plate 34 (partition frame 38) can be moved along the rails 48, making it easy to change the position of the partition plate 34.

[0043] The rail 48 is formed with bolt holes 50. By the simple operation of aligning the bolt holes 50 with the mounting holes 54 of the partition frame 38 and tightening the bolts 42, the partition plate 34 can be attached to the rail 48 at a desired position.

[0044] The partition member 32 has a partition frame 38 and a partition plate body 40. Therefore, a plurality of types of partition plate bodies 40 with different shapes and materials can be prepared, and the partition plate bodies 40 can be replaced.

[0045] A plurality of through holes 58 are formed in the partition plate body 40. Even when the interior of the fluid tank body 20 is divided by the partition member 32, it is possible to move (circulate) the fluid between the first area 312 and the second area 314 through the through holes 58.

[0046] The shape, position, and opening cross-sectional area of ​​the through-holes 58 can be appropriately set in consideration of the amount, state, etc. of the fluid in the fluid tank body 20. In the example shown in Figures 3 and 4, the circular through-holes 58 are formed over the entire surface of the partition plate body 40, so that the fluid can move between the first region 312 and the second region 314 over the entire surface of the partition plate body 40 (from the top, through the middle, to the bottom).

[0047] 6 allows the fluid to move between the first region 312 and the second region 314 at the upper and lower parts of the partition plate main body 40. Also, the opening cross-sectional area of ​​each of the through holes 60 is larger than that of the through holes 58, so there is less resistance to the movement of the fluid. In other words, less energy is required to circulate the fluid inside the fluid tank main body 20.

[0048] For example, it is possible to prepare a plurality of types of partition plate bodies 40 each having a different shape and arrangement of the through holes 58, and replace the partition plate body 40 with the partition frame 38. In this way, the partition frame 38 can be made common to a plurality of partition plate bodies 40, thereby enhancing versatility and enabling the partition member 32 to be constructed at low cost.

[0049] In the above, an example has been given in which a plurality of bolt holes 50 are formed in the rail 48, and the bolt holes 50 are aligned with the mounting holes 54 of the partition frame 38, and the partition plate 34 is attached to the rail 48 (holding member 36) by the bolts 42. The configuration for attaching the partition plate 34 to the rail 48 at a desired position is not limited to this. For example, a rack gear may be formed on the rail 48, and a pinion gear may be provided on the partition frame 38, and the partition frame 38 may be attached to the rail 48 by meshing between the rack gear and the pinion gear. In this structure, the partition frame 38 can be held at any position of the rack gear. Also, the position of the partition frame 38 can be adjusted simply by rotating the pinion gear. In this configuration, a locking mechanism for locking the pinion gear or the partition plate 34 at a predetermined position may be provided.

[0050] The pinion gear can be rotated, for example, by providing an operating lever coaxial with the pinion gear and manually rotating the operating lever. A motor for rotating the pinion gear may also be provided. Furthermore, a configuration may be adopted in which the amount and quality of wastewater in the first area 312 and the second area 314 are detected by a sensor, and the motor is controlled based on the detection results to rotate the pinion gear. In this configuration, it is possible to automatically move the partition plate 34 to an appropriate position based on the amount and quality of wastewater in the first area 312 and the second area 314.

[0051] In the above, an example was given in which the normal direction of the partition plate body 40 is arranged in a direction that coincides with the width direction of the fluid tank body 20, but the direction of the partition plate body 40 is not limited. For example, depending on the configuration of the fluid tank body 20, the normal direction of the partition plate body 40 may coincide with the depth direction or the up-down direction of the fluid tank body 20. Also, the normal direction of the partition plate body 40 may be a direction inclined from the width direction of the fluid tank body 20. Furthermore, a configuration in which the holding member 36 rotatably holds the partition plate 34 and thereby holds it at a plurality of holding positions is also included.

[0052] In the above, the configuration of the liquid treatment device 16 incorporated in the water circulation system 12 shown in Fig. 1 has been exemplified as the fluid treatment device, but the fluid treatment device is not limited to the liquid treatment device 16. For example, it may be a gas treatment device that treats gas as a fluid.

[0053] In the disclosed technology, the number of divisions when the inside of the fluid tank main body 20 is divided is not limited to two, and a configuration in which the inside is divided (divided) into three or more parts is also possible. For example, by arranging two partition plates 34, the inside of the fluid tank main body 20 can be divided (divided) into three parts.

[0054] In addition, the following notes are disclosed: (Appendix 1) a partition plate for partitioning the inside of a fluid tank body that contains a fluid; a holding member capable of holding the partition plate at a plurality of holding positions inside the fluid tank body; A partition member having the following structure.
