An endless filter cloth belt 4 that does not receive any windings is parallel to a drive roller 6.6 and a plurality of roller groups 7.7, which are connected to a drive device 5 and rotate at the same speed, in a face-to-face overlapping state. It is mounted so that it can be driven.

の太陽ローラ13に対する公転が行われることになる。Furthermore, as shown in FIGS. 2 and 3, the structure of the shear dewatering section S includes a sun roller 13 and a plurality of planetary rollers 14 circumscribing the sun roller 13. Both ends of the rotating shaft 150 of the sun roller 13 The sun roller 13 and the i1M roller 14 are both rotatably supported by a circular support member 17 having a gear formed on its outer periphery, and the outer gear portion of the support member 17 is not shown. It is meshed with a pinion gear 20 rotated by a chain wheel 18 connected to a variable speed motor via a chain 19. That is, the support member 17 is rotated by the variable speed motor via the chain wheel 18 and the pinion gear 20, and as the support member 17 rotates, the planetary roller 14
The sun roller 13 revolves around the sun roller 13.

濾布ベルト3.4間に挟持しつつ加圧ローラ8部に至っ
て加圧脱水される。The sludge 1 to be dewatered is supplied from the supply section 2 onto the filter cloth heald 3 running, is transported while being dehydrated by gravity, and is turned and polymerized face-to-face with the filter cloth belt 4, so that the sludge 1 is transferred to both filters. While being held between the cloth belts 3 and 4, it reaches the pressure roller 8 section and is dehydrated under pressure.

させて効率的な脱水が行われる。Next, this pressurized and dehydrated lη mud reaches the shear dewatering section S while being held between the filter cloth belts 3.4, runs outside of the plurality of planetary rollers 14 while being under tension, and sequentially passes through the planetary rollers 1.
At this time, by rotating the support member 17 with a motor, the polymerized filter cloth heald 3.4 is subjected to a shearing force due to the rotation speed 1 of the planetary roller 14 shown in FIG.
Driving speed different from 2 is possible. Therefore, the contact portion between the A-leg roller 14 and the polymerized filter cloth heald 3.4 moves by the relative speed caused by the difference between the revolution speed (1) of the 't1ffi roller 14 and the running speed (2) of the polymerized filter cloth belt 3.4. However, efficient dewatering is performed by increasing or decreasing the number of times of shearing by the planetary rollers 14.
このようにして加圧脱水及び剪断脱水を受けた汚泥は、
次いで圧搾ローラ9にて圧搾されたのち濾布ヘルド3.
4が解離され、脱水ケーキ10は剥離落下してコンベヤ
11により搬送される。The sludge that has undergone pressure dewatering and shear dewatering in this way is
The filter cloth is then compressed by a pressing roller 9 and then transferred to the filter cloth heald 3.
4 is separated, and the dehydrated cake 10 peels off and falls and is conveyed by the conveyor 11.
なお、剪断脱水部Sは図示例では1箇所に配備しである
が、重合濾布ベルト3.4の走行路の複数箇所に配備す
ることもできる。Although the shearing and dewatering section S is arranged at one location in the illustrated example, it can also be arranged at multiple locations along the travel path of the polymerized filter fabric belt 3.4.
また、上記実施例では遊星ローラ14を太陽ローラ13
に対し公転させるために支持部材17を駆動することに

の公転を行うこともできる。Further, in the above embodiment, the planetary roller 14 is replaced by the sun roller 13.
Although this was done by driving the support member 17 to revolve around the sun roller 13, the sun roller 13 is driven to rotate, and in conjunction with this rotation, the planetary roller 14 is rotated together with the support member 17.
It is also possible to perform a revolution.
以上述べたように本発明によれば、剪断脱水部における
剪断回数を、剪断ローラの数に制限されることなく調節
することができるから、常に汚泥の性状に対応して脱水
効率を向上させることができるものである。As described above, according to the present invention, the number of times of shearing in the shearing dewatering section can be adjusted without being limited by the number of shearing rollers, so that the dewatering efficiency can always be improved in accordance with the properties of the sludge. It is something that can be done.
