[Problem that the idea aims to solve]

However, in the above-mentioned conventional sludge dewatering device, the opening/closing member 1 of the back pressure cylinder device 15 is 5a closed, put in the residue, and operate the pressurizing cylinder device 16 in the direction A. The residue x is discharged by opening the opening/closing member 15a of the back pressure cylinder device 15, After moving the pressurizing cylinder device 16 in direction B, the next sludge x is introduced. Since it is a complete batch method, it is inconvenient and difficult to use.

0004 This invention solves the above problems and provides a residue dewatering device that is easy to use. The purpose is to

[0005]

[Means to solve the problem]

In order to solve the above problem, the sludge dewatering device of the present invention has multiple drainage holes. A filtration plate that has been filtered is installed at an angle below the sludge inlet, and an oblique Place the squeezing cylinder device in the direction of the inclination of the filter plate so that the axis of the piston is aligned upward. Multiple stages are arranged side by side, and the egress/return rod of each squeezing cylinder device pushes the residue onto the filter plate. A compression member is provided for basting and compression, and the part diagonally below the final stage compression position is opened and closed. It is equipped with a discharge device that allows the squeezed residue to be discharged to the outside.

[0006]

[Effect]

With the above configuration, the residue is input from the residue input port onto the slanted filter plate, and the residue is fed into each stage. The squeezing cylinder device is operated in sequence to compress the residue in stages using the squeezing member and discharge it. By allowing the discharge device to discharge the residue downward, the residue can be squeezed quasi-continuously. can be discharged.

[0007]

【Example】

Hereinafter, one embodiment of the present invention will be described based on the drawings. In Fig. 1, a filter plate 1 is installed in an inclined manner below a hopper 2 for feeding sludge. A plurality of drainage holes 3 are formed therethrough. Into this filter plate 1 from diagonally above. Two compression cylinder devices 4, 5 and one discharge cylinder device 6 facing each other and each cylinder device 4, 5, 6 has a piston in a direction perpendicular to the filter plate 1. Three filter plates are arranged in parallel in the inclination direction of the filter plate 1 so that the axes 4a, 5a, and 6a of the filter plate 1 are aligned. ing. And the retractable rods 4b, 5b of the upper compression cylinder devices 4, 5 , pressing members 4c and 5c press and squeeze the residue X against the filter plate 1 from diagonally above. is attached to the retractable rod 6b of the lower discharge cylinder device 6, The lower part of the movement space of the compression member 5c of the second-stage compression cylinder device 5 is opened and closed to perform compression. An opening/closing member 6c is attached that allows the squeezed residue X to be discharged downward. Note that 7 is an input port for the residue X, and 8 is a discharge port.

[0008] Next, the process of dehydrating the residue in the above configuration will be explained. First, as shown in FIG. 2(a), the compression member 4 of the first stage compression cylinder device 4 C is moved in the direction away from the filter plate 1, and the residue X in the input hopper 2 is transferred to the filter plate. Introduce it on top of 1. At this time, the opening/closing member 6c of the discharge cylinder device 6 is pressed against the filter plate 1. The discharge side is closed by basting, and the compression member 5c of the second stage compression cylinder device 5 is It has been separated from the filter plate 1, and the residue X in the input hopper 2 has been squeezed first Following the residue X, the compressing member 4c of the first stage compressing cylinder device 4 and the filter plate 1 introduced between.

[0009] Next, as shown in FIG. 2(b), the compression member of the first stage compression cylinder device 4 is 4c is moved to the filter plate 1 side and the residue X is squeezed. At the same time, the second stage compression The pressing member 5c of the cylinder device 5 is also moved to the filter plate 1 side.

0010 Then, the compression member 5 of the second stage compression cylinder device 5 as shown in FIG. 2(c) c and the step of separating the opening/closing member 6c of the discharge cylinder device 6 from the filter plate 1. After that, as shown in FIG. 2A, the opening/closing member 6 of the discharge cylinder device 6 is opened again. For the first and second stage compression, press c against the filter plate 1 and close the discharge side. The compression members 4c and 5c of the cylinder devices 4 and 5 are moved in the direction away from the filter plate 1. let As a result, the residue X in the input hopper 2 is simultaneously introduced onto the filter plate 1. The residue X compressed by the first stage compression cylinder device 4 is transferred to the second stage compression cylinder device 4 It is introduced between the squeezing member 5c of the filter device 5 and the filter plate 1.

[0011] After this, as shown in FIG. 2(b), the first and second stage compression cylinder equipment is Move the squeezing members 4c and 5c at positions 4 and 5 to the filter plate 1 side, and use them for feeding as described above. At the same time as squeezing the residue X from the hopper 2, the first stage squeezing cylinder device 4 The residue X squeezed by Squeeze further.

0012 Finally, the second stage compression cylinder device 5 as shown in FIG. 2(c) is used for compression. The member 5c and the opening/closing member 6c of the discharge cylinder device 6 are separated from the filter plate 1. . As a result, the compressed material is compressed by the compressing member 5c of the second-stage compressing cylinder device 5. The residue X is discharged from the discharge port 8 to the outside.

[0013] Through the above steps, the residue X is semi-continuously compressed and discharged. Shimizu X Since it is squeezed in two stages, it has a low moisture content and the residue X can be discharged. In addition, this fruit In the example, the case of compressing in two stages was described, but it is also possible to compress in multiple stages. . In addition, although the discharge cylinder device 6 was used as the opening/closing member, a simple opening/closing device was used. You can stay there. Note that by using the discharge cylinder device 6 as described above, the structure can be improved. It has the advantage of being simple in structure and easy to install.
