あつた。 Belt presses are attracting attention as an effective means for dewatering slurry such as sludge generated in sewage treatment facilities. This belt press dehydrates the slurry by compressing it between a pair of cloths that form an endless belt, so in order to achieve a high level of dehydration and obtain a cake with a low moisture content, it is necessary to compress the slurry between the two cloths. It is necessary to increase the pressure. However, as the pressure increases, the sludge is strongly pressed into the pores of the cloth, making it difficult to remove the dehydrated sludge and easily clogging the cloth. Conventional cleaning equipment that sprays cleaning water at the cloth in one step has the disadvantage that it is difficult to remove the stains and also requires a large amount of cleaning water.

行する無端ベルト状の上側布１１とを有する。 An embodiment of this invention will be described below with reference to the drawings. The belt press shown in FIG.
an endless belt-shaped lower cloth 8 that sequentially passes over the circumferential surfaces of rollers 1 to 7 and runs in the direction of the arrow; and an endless belt that runs in the direction of the arrow and passes over the circumferential surfaces of rollers 9, 2 to 6, and 10. It has an upper cloth 11 having a shape.

浄装置１２についてのみ説明する。 Slurry A to be dehydrated is supplied between cloths 8 and 11 at a position in front of roller 6, and is dehydrated while passing over the circumferential surfaces of rollers 6 to 2 while being held between them, and cake B is formed. It is discharged when passing over roller 1. Further, cloth cleaning devices 12 and 13 are provided behind the rollers 1 and 9, respectively, in order to clean the lower cloth 8 and the upper cloth 11. In a belt press that uses a pair of cloths, the lower cloth usually tends to become clogged, so the cloth cleaning device 13 for the upper cloth is substantially the same as the cleaning device 12 for the lower cloth. However, it may be the same as the conventional one. Here, only the cloth cleaning device 12 provided on the lower cloth 8 will be described.

有している。 Cloth cleaning device 12 for cleaning the lower cloth 8
As shown in FIG. 2, there is a cleaning box 15 which has a depth that can accommodate the cleaning drainage water 14 and has a lid to prevent the cleaning water from spilling out, and a cleaning box 15 that runs the cloth 8 along a predetermined path for cleaning. It has a return roller 16 for guiding into the box 15, a preliminary cleaning nozzle 17, a cleaning nozzle 18 and a plurality of idle rollers 19 arranged inside the cleaning box 15.

例を示したが２以上の洗浄ノズルを同様に配置し
た場合はより効果的な洗浄が行なわれる。 The preliminary cleaning nozzle 17 and the cleaning nozzle 15 are
These two nozzles are for spraying washing water onto the cloth 8, and both are arranged to face the upper surface of the cloth 8. Among these two nozzles, the preliminary washing nozzle 17 is installed on the entrance side of the cloth 8 of the washing box 15. ing. Further, the preliminary washing nozzle 17 is designed to spray a smaller amount of washing water onto the cloth 8 than the washing nozzle 18. Although this embodiment shows an example in which two cleaning nozzles are arranged, more effective cleaning can be performed if two or more cleaning nozzles are arranged in the same way.

よい。 A plurality of idle rollers 19 are provided on or fixed to a horizontal rotating shaft so as to be in contact with the lower surface side of the cloth 8 at positions facing the pre-cleaning nozzle 17 . In this embodiment, an example in which three idle rollers are arranged is shown, but the number may be one or two or more.

め、その除去は容易に行なえる。 In the cloth cleaning device 12 configured in this way, the cloth 8 after the slurry has been dehydrated is guided into the cleaning box 15 by the return roller. At this time, the cloth 8 is subjected to tension by the idle roller 19, so that the sludge filled in the pores of the cloth 8 floats up, and when it receives a small amount of wash water from the pre-wash nozzle 17, the wash water It becomes swollen and easily removed by the subsequent jet of washing water. In addition, by spraying this preliminary washing water,
A portion of the sludge adhering to the cloth 8 is washed away.
At the same time, a portion of the sludge is scraped off by the idle roller 19 that comes into contact with the lower surface of the cloth 8, and at this stage, a portion of the sludge falls off from the cloth 8. At this time, among the plurality of idle rollers, the sludge that is scraped off by the idle roller 19 that rubs against the sludge that has swelled due to the injection of cleaning water cannot be completely removed by the preceding idle roller 19; Since the sludge is swollen, it can be easily removed.
従つて、その後に、洗浄ノズル１８からの洗浄
水を受けたときに、布８の細孔に充填されて残
存する汚泥物は容易に除去され、また必要な洗浄
水の量も少量で済む。 Therefore, when the cloth 8 subsequently receives cleaning water from the cleaning nozzle 18, the remaining sludge that fills the pores of the cloth 8 is easily removed, and only a small amount of cleaning water is required.

て済む。 As described above, according to the cloth cleaning device of this invention, after dewatering, the cloth is placed in the cleaning box under tension by the idle rollers, with the sludge floating thereon, and a small amount of cleaning water is applied to the cloth. At the same time, a portion of the swelling is scraped off by an idle roller, and then a full-scale jet of cleaning water is applied. Therefore, sludge can be removed extremely easily, and the amount of washing water required is also small.
なお布の目詰まりは高圧なものほどまた、上
側布よりは下側布に起りやすいので、そのよ
うな場合に特に適する。 It should be noted that the higher the pressure, the more likely the lower cloth will be clogged than the upper cloth, so this method is particularly suitable for such cases.
