The trunk wall part 63 includes a front wall part 64, a rear connection part 65, an inlet part 66, a dewatering part 67, an outlet part 68, and a standby part 69 (see FIG. 2). The width T in the circumferential direction of the rotating body 1 in each of the accommodating portions 51 is the same. The width T is smaller than the widths of the inlet hole 66a of the inlet portion 66, the dewatering portion 67, the outlet hole 68a of the outlet portion 68, and the standby portion 69 along the circumferential direction of the rotating body 1. The dehydrating unit 67 includes a dehydrating plate 71 and an outer plate 72. The dewatering plate 71 is disposed along the outer peripheral surface 32 of the rotating body 1. The dehydrating plate 71 is formed to have a size that covers the openings 35 of the plurality of accommodating portions 51 formed along the outer peripheral surface 32 of the rotating body 1. For example, as shown in FIG. 1, the dehydrating plate 71 is formed in a cross-sectional arc shape in an angle range that covers the five accommodating portions 51, extends along the cylinder length direction of the rotating body 1, and the outer peripheral surface of the rotating body 1 32 is covered in the above angle range. The dehydrating plate 71 is formed with dehydrating holes 73 through which the liquid of the solid-liquid mixture passes from the outer peripheral surface 32 side of the rotating body 1 to the outer plate 72 side. That is, the dewatering plate 71 is formed by a perforated plate such as punching metal (see FIG. 4). The dewatering hole 73 is formed so as to gradually increase in diameter from the inner surface 71a side to the outer surface 71b side of the dewatering plate 71. For example, the inner surface 71a has a diameter of 2 mm and the outer surface 71b has a diameter of 3 mm. Similar to the dewatering plate 71, the outer plate 72 is formed in a cross-sectional arc shape in an angular range that covers the five accommodating portions 51, and extends along the direction in which the cylinder of the rotating body 1 extends. Although it is a plate that covers the surface 32 within the above-mentioned angle range, the diameter is larger than that of the dewatering plate 71 because it is disposed outside the dewatering plate 71 so as to face the outer surface 71 b of the dewatering plate 71. The dewatering plate 71 and the outer plate 72 are connected to each other by a column 74 and a set screw (not shown). A drainage space 77 is formed by a space surrounded by the dewatering plate 71 and the outer plate 72.

A drain hole 78 is formed in the outer plate 72 below the drain space 77, and a drain pipe 79 is connected to the drain hole 78. A drainage pump 80 is connected to the drainage pipe 79, and water discharged into the drainage space 77 is sucked by the drainage pump 80 and sent to a water storage unit (not shown). That is, since the plurality of accommodating portions 51 are provided at predetermined intervals in the direction along the outer periphery of the rotating body 1 and the dehydrating plate 71 is formed to have a size that covers the openings 35 of the plural accommodating portions 51, The dewatering section can be lengthened, and continuous dehydration processing with a long dehydration time is possible. Moreover, since the drain hole 78 connected to the drainage space 77 is provided in the outer plate 72, drainage treatment can be performed efficiently.

  The inlet 66 is connected to one end 81 of the dewatering unit 67. The outlet portion 68 is connected to the other end portion 82 of the dewatering portion 67. The width length a of the portion along the circumferential direction of the rotating body 1 in the outlet hole 68a of the outlet portion 68 is such that all of the openings 35 in one storage portion 51 correspond to the outlet hole 68a. The opening 35 in the other accommodating part 51 is set to a length that does not correspond to the outlet hole 68a. Specifically, the length of the width along the circumferential direction of the rotating body 1 in the opening 35 of the accommodating portion 51 is T, and the outer surface 33 of the partition wall body 16 constituting the outer peripheral surface 32 of the rotating body 1 When the length of the width of the portion along the circumferential direction of the rotating body 1 is b, T <a <(T + b) is set. By setting in this way, the portion other than the outlet portion 68, in particular, the range of the dewatering portion 67 can be lengthened, so that continuous dewatering can be performed efficiently.

  The standby unit 69 is connected to the other end 83 of the inlet 66 and the other end 84 of the outlet 68, and separates the inlet 66 and the outlet 68. The outlet portion inner surface 85 that forms the boundary between the standby portion 69 and the outlet portion 68 forms a residual solid scraping portion that scrapes off the solid adhering to the outer surface 44 a of the pusher 44 that passes through the outlet portion 68. Accordingly, since the solid adhering to the outer surface 44a is scraped off by the remaining solid scraping portion before the accommodating portion 51 that has passed through the outlet portion 68 reaches the inlet portion 66, the accommodating portion 51 that reaches the inlet portion 66 is in each case. Since a fixed amount of solid-liquid mixture can be accommodated, the processing efficiency can be improved.

  As shown in FIG. 2, the front wall portion 64 and the rear wall portion 62 are provided with bearings 90 and 91 that rotatably support the rotary shaft 10.

When the portion 67 is connected to the inner surface 76 of the rear wall portion 62 and the inner surface 75 of the front connecting portion 61 by a set screw (not shown), the casing 2 that rotatably accommodates the rotating body 1 and surrounds the rotating body 1 is formed. Assembled. A rotation transmission belt 93 is wound around the motor shaft 92 and the rotation shaft 10 of the motor 3 separately provided on the rear wall 62, and the rotational force of the motor shaft 92 is transmitted to the rotation shaft 10 via the rotation transmission belt 93. The An angle sensor (encoder) 95 is attached to one end of the rotating shaft 10 connected by the motor shaft 92 and the rotation transmission belt 93, and the angle sensor 95 and the control device 96 are connected to each other by a signal line 97. The angle sensor 95 is configured so that the position of the outer peripheral surface of the rotary shaft 10 that intersects the line connecting the center of the rotary shaft 10 and the center of the cross section of any one partition wall body 16 becomes the angle detection reference (origin). Attached to. The control device 96 and the hydraulic control valve 56 are connected to each other by a control signal line 98. The casing 2 is provided with a base such as a fixed base and a fixed arm (not shown), and the solid-liquid separation device can be stably installed on the installation surface by the base. A drive control mechanism 99 for the pusher 44 is configured by an oil system such as the control device 96, the pressurizing mechanism 41, the oil tank 52, the oil feeding cables 53; 54; 54, and the hydraulic control valve 56.

In FIG. 1, description will be made assuming that the position of the outer peripheral surface of the rotating shaft that intersects the imaginary line W is set as the angle detection reference (origin) of the angle sensor 95. Further, in FIG. 1, the pressurizing mechanism 41 that was initially in the position (1) is moved along with the rotation of the rotating body 1 (2), (3), (4), (5), (6), The movement history of the pusher 44 when it moves to the positions (7) and (8) is shown. First, when the solid-liquid mixture is supplied to the inlet 66 and the rotation shaft 10 is rotated in the direction of the arrow e by the motor 3 from the state of FIG. The pressurizing mechanism 41 at the position) comes to the position (2). In this case, the control device 96 inputs the fact that it has rotated 45 degrees from the angle sensor 95 and controls the hydraulic control valve 52 so as to start supplying hydraulic pressure to the cylinder 42 of the pressurizing mechanism 41 that has reached the position (2). . As a result, the pressing body 44 provided at the tip of the pressing body 43 of the pressurizing mechanism 41 moves in the direction of the outer peripheral surface 32 of the rotating body 1, and the solid-liquid mixture is pressed in the direction of the dehydrating plate 71 by the pressing body 44. Thus, the water in the solid-liquid mixture is discharged to the drainage space 77 through the dehydration hole 73. Further, when the rotary shaft 10 rotates, the pressurizing mechanism 41 that was initially in the position (1) advances sequentially to the positions (3), (4), (5), and (6). The control device 96 controls the hydraulic control valve 56 so that the pressing body 44 gradually moves in the direction of the outer peripheral surface 32 of the rotating body 1 as the pressurizing mechanism 41 approaches the position (6) from the position (1).

Thus, the hydraulic control valve 56 is controlled. When the control device 96 rotates 315 degrees from the origin position, that is, when the pressurizing mechanism 41 initially in the position (1) comes to the position (7), the control device 96 controls the hydraulic control valve 56 to pressurize. The push body 43 of the mechanism 41 is extended to the maximum, and the push body 44 is moved until the outer surface 44 a of the push body 44 comes to the position of the outer peripheral surface 32 of the rotating body 1. Then, when the pressurization mechanism 41 initially in the position (1) comes to the position (8), the control device 96 controls the hydraulic control valve 56 to contract the push body 44 of the pressurization mechanism 41. Control is performed so that the pusher 44 starts to be lowered toward the bottom surface of the recess 36 (the outer surface 31 of the flat plate 21).

That is, the solid-liquid mixture is accommodated in the accommodating portion 51 provided on the outer peripheral surface 32 of the rotating body 1, and the solid-liquid mixture accommodated in the accommodating portion 51 is rotated along the outer peripheral surface 32 of the rotating body 1. Since the solid-liquid mixture is dehydrated by pushing it with the pusher 44 in the direction of the dewatering plate 71 arranged in a row, it is necessary to provide a long cylinder to press the solid-liquid mixture or to transport the solid-liquid mixture. The device can be reduced in size.
In the best mode, a plurality of storage portions 51 are provided at predetermined intervals in a direction along the outer periphery of the rotating body 1, and a dehydrating plate 71 having a size that covers the openings 53 of the plurality of storage portions 51. Since the solid-liquid mixture is continuously accommodated in the plurality of accommodating portions 51 as the rotating body 1 rotates, the solid-liquid mixture accommodated in the plurality of accommodating portions 51 can be continuously dehydrated. That is, the dehydration process can be performed efficiently.

  The number of the accommodating parts 51 provided in the outer peripheral surface 32 of the rotary body 1 should just be one or more. Instead of the hydraulic drive pressurization mechanism 41, a hydraulic drive or pneumatic drive pressurization mechanism, or a pressurization mechanism using a cam and a spring may be used. Further, the accommodating portion that becomes wider as it approaches the outer peripheral surface 32 from the rotating shaft 10 side of the rotating body 1, that is, the wall surface of the partition wall body that partitions the accommodating portion is formed in a plane parallel to the radial line of the rotating body, It is also possible to use an accommodating portion having a wall surface diverging, and a pusher whose width is variable by a spring mechanism or the like.
