However, the number of times of shearing in such a shear dewatering section is determined by the number of shearing rollers, but since the sludge is soft, it tends to protrude from the cloth belt, and in order to prevent this sludge from protruding, it is necessary to suddenly apply high pressure. Dehydration was not possible, and the expected dehydration often did not occur.

The operation of the present invention will be explained with reference to the drawings showing one embodiment thereof. FIG. 1 is an explanatory view of the overall configuration, and shows an endless cloth belt 3 provided with a supply section 2 for sludge 1; An endless cloth belt 4 that is not supplied with sludge 1 is connected to a drive device 5 and runs parallel to drive rollers 6, 6 and a plurality of roller groups 7, 7, which rotate at the same speed, facing each other in a superimposed state. It is possible to hang it.

るようになつている。 In addition, pressure rollers 8, 8, . A shearing dehydration section S is provided, and the polymerized cloth belts 3 and 4 are run over this shearing and dehydration section S. After passing through a pressing roller 9, the cloth belts 3 and 4 are separated, and the dehydration cake 10 is peeled off. and falls onto the conveyor 11.

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 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 dehydrated 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.

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.
さらに本発明では、第４図矢印に示すように、

が防止される。 Furthermore, in the present invention, as shown by the arrow in FIG.
Since the direction of revolution of the planetary rollers 14 is the same as the running direction of the cloth belts 3 and 4, a part of the water in the sludge does not move back to the sludge-intake area, but instead moves to the outlet side of the dewatered cake. I decided to do it,
As a result of preventing an increase in moisture on the side where the sludge is trapped, sludge is prevented from protruding from the cloth belts 3 and 4.
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.

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, and while preventing sludge from spilling out, it is always possible to adjust to the properties of the sludge. This makes it possible to improve dehydration efficiency.
