Both ends of the rotating shaft 15 of No. 3 are rotatably held by a frame 16, and both the sun roller 13 and the planetary roller 14 are rotatably supported by a circular support member 17 having a gear formed on the outer periphery. The outer peripheral gear portion of the support member 17 is meshed with a pinion gear 20 that is rotated by a chain wheel 18 connected to a variable speed motor (not shown) 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 at the same time, the planetary roller 14 revolves around the sun roller 13.

との接触部が移動し、遊星ローラ１４による剪断
回数を増減させて効率的な脱水が行われる。 Therefore, the sludge 1 to be dewatered is supplied to the supply section 2
The sludge is supplied onto the running cloth belt 3 and transported while being dehydrated by gravity, and is turned and polymerized facing the cloth belt 4, and reaches the pressure roller 8 while sandwiching the sludge 1 between both cloth belts 3 and 4. It is then pressurized and dehydrated.
Next, this pressurized and dewatered sludge is transferred to a cloth belt 3,
4, and travels outside the plurality of planetary rollers 14 under tension while reaching the shearing dewatering section S.
They are sequentially subjected to shearing force by the planetary rollers 14, but at this time, by rotating the support member 17 with the motor, the running speed of the polymeric fabric belts 3, 4 running at the revolution speed V1 of the planetary rollers 14 shown in FIG. It enables different driving than V2 . Therefore,
The planetary roller 14 and the polymeric fabric belts 3, 4 are rotated by the relative speed caused by the difference between the revolution speed V1 of the planetary roller 14 and the running speed V2 of the polymeric fabric belts 3, 4.
The contact portion moves and the number of times of shearing by the planetary rollers 14 is increased or decreased to perform efficient dewatering.

て剪断回数を増加させることもできる。 Furthermore, during this shear dehydration, the planetary roller 14 receives a radial force generated by the tension of the fabric belts 3 and 4, but since the sun roller 13 is in contact with the planetary roller 14 in the same radial direction, the planetary roller 14 is The radial force received by the roller 14 is directly transmitted to the sun roller 13. Therefore, in the planetary roller 14, there is no need to consider the bending of the planetary roller 14 in the length direction with respect to the radial force received from the cloth belts 3 and 4, and therefore, it is not necessary to consider the bending of the planetary roller 14 in the length direction. The diameter of the planetary roller 14 can be reduced. That is, when the planetary rollers 14 are arranged on the same trajectory, the diameter of the planetary rollers 14 can be reduced by providing the sun roller 13, so a large number of planetary rollers 14 can be arranged, This also makes it possible to increase the shearing frequency.
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
布ベルト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 been subjected to pressure dewatering and shear dewatering in this manner is then compressed by a pressing roller 9, and then the cloth belts 3 and 4 are separated, and the dewatered cake 10 is peeled off and transported by a conveyor 11.
なお、剪断脱水部Ｓは図示例では１箇所に配備
してあるが、重合布ベルト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 provided at one location in the illustrated example, it may also be provided at multiple locations along the travel path of the polymer fabric belts 3 and 4.
また、上記実施例では遊星ローラ１４を太陽ロ

公転を行うことができる。 Further, in the above embodiment, the supporting member 17 is driven to make the planetary roller 14 revolve around the sun roller 13, but the sun roller 13
This rotation and the cloth belts 3 and 4
The planetary rollers 14 can be rotated in relation to the running of the sludge so as to apply a shearing force suitable for the properties of the sludge to be dewatered.
さらに、太陽ローラ１３はこのように遊星ロー

の調節も容易となる。 Furthermore, the sun roller 13 not only supports the planetary roller 14 in this way, but also supports the planetary roller 14 at a speed different from the running speed of the polymeric fabric belts 3, 4.
By rotating in contact with the sun roller 13 when rotating, the tension newly generated in the cloth belts 3 and 4 is reduced, the driving power of the drive device 5 is reduced, and shearing force is easily applied to the sludge. It also makes it easier to adjust the number of times of shearing.

As described above, according to the present invention, the combined structure of the sun roller and the planetary roller not only increases the supporting force of the planetary roller with the sun roller, but also allows the traveling speed of the cloth to vary depending on the properties of the sludge. The number of times the planetary rollers shear the sludge can be adjusted by rotating the planetary rollers at different speeds, and the speed of the planetary rollers can be easily adjusted to match the properties of the sludge in relation to the rotation of the sun roller and the running speed of the cloth belt. In addition, the tension generated in the cloth can be reduced to reduce wear and tear on the cloth and rollers, prolonging their lifespan, and the driving power for the cloth can be reduced, making it possible to apply shearing force to the sludge and adjust the number of times of shearing. The dewatering efficiency of sludge can always be improved significantly.
