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. Perform a different operation than V 2 . Therefore, the revolution speed V 1 of the planetary roller 14 and the polymeric fabric belt 3,
The contact portion between the planetary roller 14 and the polymeric fabric belts 3 and 4 moves by the relative speed caused by the difference in running speed V2 between the planetary rollers 14 and the polymeric fabric belts 3 and 4, increasing or decreasing the number of times of shearing by the planetary rollers 14, thereby achieving efficient dewatering. be exposed.

する必要がなくなる。 During this shear dehydration, the planetary roller 14 receives a radial force generated by the tension of the cloth 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 The radial force received by the sun roller 13 is directly transmitted to the sun roller 13. Therefore, the planetary roller 14
In this case, 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.

もできる。 Further, in the above embodiment, the support member 17 is used to make the planetary roller 14 revolve around the sun roller 13.
This was done by driving the sun roller 1
3 may be driven to rotate, and the planetary roller 14 may revolve together with the support member 17 in conjunction with this rotation.

て効率よく脱水することができた。 According to experiments, the relative speed V 2 -V 1 caused by the difference between the revolution speed V 1 of the planetary roller 14 and the running speed V 2 of the cloth belts 3 and 4 is +3.5 m/min ~
When the speed was within the range of −1.5 m/min, dehydration was particularly stable and efficient.
