を有する。All of these devices dehydrate and convey the screen residue by pushing the screen residue upward and downward from a pipe having an upslope. Most or all of the steps of screen residue dehydration and transfer are carried out in a pipe. Therefore, there are advantages that the odor of the screen residue does not leak to the surrounding environment and the screen residue does not come into contact with the eyes of workers such as workers.

とがある。By the way, in these prior arts, the transport path is a pipeline in any of the examples, and the dehydration action of the screen residue is performed by the pressure applied to the screen residue in the pipeline. The pressure applied to the residue is caused by the movement resistance of the screen residue in the tube. Then, by pressing the screen residue,
The internal pressure of the screen residue rises, water is released, and is discharged to the outside, whereby it is dehydrated. However, the screen residue contains food residues, toilet paper, human hair, fibers, human feces, etc., and its properties are not constant, and the frictional resistance between the inner wall of the transport cylinder is significantly different, and its fluidity is also changed. . Therefore, with the conventional method of dehydrating the straight pipe part or the stepped pipe part, the resistance to the change of the screen residue cannot be made constant, so the property of the screen residue changes and the applied pressure also changes. In addition to the drawback that predetermined dehydration cannot be performed, the screen residue that has been dehydrated under pressure may expand and block the inside of the pipe when it is conveyed in the conveyance path.

In the dehydrating apparatus, the pressurizing and dehydrating section is connected to the cylindrical transport path by a bent cylindrical back pressure section, and the bent outer peripheral wall of the back pressure section is swung by the pressing means. The main point is that it is composed of a back pressure plate.

Even if the property of the residue changes, it is possible to perform a certain amount of dehydration.
