  According to the processed material leveling apparatus which concerns on this invention, the processed material put into the container can be destroyed with the rotating screw, and the processed material can be leveled automatically.

  Embodiments of the present invention will be described below in detail with reference to the drawings.

  FIG. 1 is a perspective view showing a container 2 for storing a processed product discharged from the solid-liquid separation device 3 and a processed product leveling device 1 for leveling the processed product in the container 2. FIG. It is sectional drawing. The container 2 shown in these drawings has a bottom wall 4 and four side walls 5, 6, 7, and 8 integrally connected to the bottom wall 4, and the upper part of the container 2 is open. . A plurality of casters 9 are attached to the bottom wall 4 as shown in FIG. Above the container 2, a processed material discharge port (not shown) of the solid-liquid separator 4 is located.

  As shown in FIG. 1, the processed material leveling apparatus 1 includes a frame 10 made of a highly rigid material such as metal or hard resin, and the frame 10 of this example includes a pair of longitudinal beams 11 extending in parallel. 12 and a pair of transverse beams 13 and 14 to which the longitudinal ends of these longitudinal beams 11 and 12 are fixed. End portions 13A and 14A in the longitudinal direction of the horizontal beams 13 and 14 are supported on the upper sides of the side walls 5 and 6 of the container 2, whereby the entire frame 10 is detachably mounted on the container 2.

  In addition, bearing plates 15 and 16 are respectively fixed to the horizontal beams 13 and 14 of the frame 10, and the screw 17 is rotatably supported by the bearing plates 15 and 16 via bearings 26 and 27. The screw 17 is rotatably supported by the frame 10 via bearing plates 15 and 16 and bearings 26 and 27.

  The screw 17 shown here has a shaft portion 18 and a spiral blade portion 19 formed integrally with the shaft portion 18, and each end portion in the longitudinal direction of the shaft portion 18 is set to each bearing plate 15. , 16 are rotatably supported via bearings 26, 27, respectively. The screw 17 is located above the bottom wall 4 of the container 2 and in the vicinity of the upper opening of the container 2.

  On the other hand, a drive motor 20 with a reduction gear is supported on the bearing plate 15, and an output shaft of the drive motor 20 is fixedly connected to a shaft portion 18 of the screw 17. When the drive motor 20 is operated, the screw 17 is rotationally driven around the axis of the shaft portion 18. The drive motor 20 constitutes an example of a drive device that rotationally drives the screw 17.

  A sensor 22 made of, for example, a photo sensor is fixedly supported on a support base 21 fixed to one vertical beam 11 of the frame 10. As will be described later, the sensor 22 is used to detect the height of the processing object placed in the container 2.

  A processed product containing a large amount of liquid is put into the solid-liquid separation device 3, and the liquid content in the processed product is separated. In this way, the processed material with a reduced liquid content is discharged little by little from the processed product discharge port of the solid-liquid separator 3 and falls into the container 2 as shown in FIG. At this time, as described above, the processed product OB placed in the container 2 accumulates in a mountain shape, but in the state where the processed product OB is shown by a solid line in FIG. Since the top of is located below and larger than the screw 17, the screw 17 does not rotate.

  The sensor 22 detects that the processed product OB in the container 2 reaches the screw 17 as shown by a two-dot chain line in FIG. 2 or that the height of the processed product OB is slightly higher than the screw 17. Then, the detection signal is taken into a control device (not shown), and the drive motor 20 starts operating in response to a command from the control device, and the screw 17 starts to rotate. When the sensor 22 detects that the height of the processed product OB in the container has reached a predetermined value, the screw 17 starts to rotate. By rotating the screw 17 in this way, as shown by an arrow A in FIG. 2, the processed product OB having a mountain shape is collapsed, and the processed product OB is spread over the entire container 2. In this way, the processed product OB placed in the container 2 is automatically leveled, so that it is not necessary to break the mountain-shaped processed product manually as in the prior art.

  As described above, as shown in FIG. 3, when a large amount of the processed object OB is stored in the container 2, the frame 10 is lifted together with the drive motor 20 and the screw 17 by the frame lifting / lowering device 23. Next, while the caster 9 is rolling, the container 2 is moved as shown by an arrow B in FIG. 3, and this is transported to, for example, a disposal site by an automobile or the like, and the processed material in the container 2 is discarded.

  On the other hand, after the container 2 is moved in the direction of arrow B, a new empty container is moved to the same position as the illustrated container 2, and then the frame 10 is lowered by the frame lifting / lowering device 23. The frame 10 is placed on the surface. In this way, the processed product can be stored in a new container in exactly the same manner as described above.

  As shown in FIG. 1, the frame lifting device 23 of this example includes a hook 24, a driving device (not shown) that lifts and lowers the hook 24, and a chain 25 that is hooked on the hook 24. Each end portion of 25 is hooked to the frame 10. When the above-described driving device is activated, the hook 24 moves up and down, thereby raising or lowering the frame 10. In the figure, the chain 25 is shown in a simplified manner.

  As described above, the processed material leveling apparatus 1 of the present example includes the screw 17 for leveling while rotating the processed material OB that has been subjected to the liquid removal treatment by the solid-liquid separator 3 and placed in the container 2. With the screw 17, the processed product OB can be leveled efficiently. In addition, the processed material leveling apparatus 1 of this example includes a sensor 22 that detects the height of the processed material OB placed in the container 2, and the height of the processed material OB in the container 2 is set to a predetermined value by the sensor 22. It has a screw drive control device that starts the rotation of the screw 17 when it is detected that it has been reached. In the illustrated example, a drive control device is configured by the drive motor 20 and the control device described above. With such a configuration, when the height of the processed object OB in the container 2 is low and it is not necessary to level it, the screw 20 can be stopped, and when it is necessary to level the processed object OB, The rotation of the screw 17 can be automatically started.

  In addition, the processed material leveling apparatus 1 of the present example has a frame 10 that is detachably mounted on the container 2 and supports the screw 17 in a rotatable manner, and the frame 10 is to be detached from the container 2. The frame elevating device 23 elevates and lowers the frame 10. As a result, it is possible to easily carry out a container containing a large amount of processed material and carry in another empty container.
