張力と、巻付角により定まる。 The applicant of this patent has disclosed in Japanese Patent Application Laid-Open No. 57-184500,
As shown in FIG. 1, a plurality of small-diameter pressure rolls 2 are disposed on the lower peripheral surface of a large-diameter main roll 1 that is rotationally driven in the direction of the arrow, so as to be movable in the direction toward and away from the main roll. The endless belt 3 whose upper surface is supplied with sludge is led to the circumferential surface of the main roll, passed between the lower circumferential surface and the pressure roll, and then turned around the final stage pressure roll 2-n, and the remaining The sludge is returned to the sludge supply position 4 while being in contact with each of the pressure rolls in the previous stage, and the cloth belt 3 presses all the pressure rolls against the main roll, and the cloth belt is circulated by the main roll. The sludge is dehydrated by gravity until the sludge is completely dehydrated, and then the sludge is dehydrated under strong pressure using the surface pressure of the belt wrapped around the main roll and the linear pressure of the pressure roll pressed against the main roll via the belt. proposed a sludge dewatering device of the above-mentioned type in which the cake is removed from a cloth belt using a doctor 5. As mentioned there, the force that presses each pressure roll against the main roll is equal to the tension of the fabric belt a
Kg/cm, and the wrapping angle α° at which the cloth belt wraps around the pressure roll when it returns while in contact with the pressure roll, and ignoring the weight of the pressure roll, is 2.a per 1 cm of width of the cloth belt. sinα/2Kg, determined by the tension of the cloth belt and the wrapping angle.

ルがメインロールに押付けられる押付力を第１段
から最終段に向かつて逐次高めることを提案し
た。 For this reason, in the previous application, the diameter of the pressure rolls was changed, and the direction of the bearing that supported each pressure roll so that it could move toward and away from the main roll, that is, the direction of movement of the pressure roll on the bearing was changed from that of the main roll. The wrapping angle of the cloth belt is adjusted by changing the angle made with respect to the radiation from the center, and the pressing force with which each pressure roll is pressed against the main roll is gradually increased from the first stage to the final stage. I suggested that.
勿論、これによつて所期の効果を達成すること
はできるが、布ベルトの巻付角はそれ以外に相
互に隣接する加圧ロールの隣接間隔の広狭で変化

ールの押付力はその軸受を揺動自在に吊下げてい
る枢着点の位置をメインロールに対し接離方向に
変化することによつて調整できることが判明し
た。 Of course, this can achieve the desired effect, but the wrapping angle of the cloth belt also changes depending on the distance between adjacent pressure rolls, and this also causes The pressing force of the pressure roll against the main roll can be adjusted, and in particular, the pressing force of the final stage pressure roll changes the position of the pivot point, which swings its bearing, toward and away from the main roll. It turns out that it can be adjusted by doing this.
そこで本発明は加圧ロールをメインロールの周

吊下げている枢着点の位置をメインロールに対し

ルのメインロールに押付く押付力を最適に調整す
る様にしたのである。 Therefore, the present invention makes it possible to adjust the pressure rolls by moving them in the circumferential direction on the circumferential surface of the main roll, thereby changing the mutual spacing, and adjusting the pivot points from which the bearings of the final stage pressure rolls are suspended as necessary. The position is adjusted by moving toward and away from the main roll, thereby optimally adjusting the pressing force of each pressure roll against the main roll.

る。 FIG. 2 and subsequent figures show one embodiment of the present invention.
Here, each pressure roll 2 except the final stage...
An upwardly extending piece 6' is attached to a bearing 6 that supports the shaft at each end of 2n-1 so as to be movable toward and away from the main roll.
, and connect the upper end of the extension piece 6' to each side wall 7 on both sides of the device.
For example, one of the extension piece 6 ' and the side wall 7 is provided with an arcuate hole centered on the pivot point P1 , and the other is provided with a bolt that moves through the arcuate hole. , adjustable fastening mechanism 8 that tightens with a nut.
Now you can attach and secure the bearing to the side wall.

る。 In other words, the pressing force of the first stage pressure roll 2- is determined by the tension of the cloth belt and the wrapping angle of the cloth belt that is in contact with it from below, as shown in Figure 3. The angle α 1 is the angle between the first stage pressure roll 2- and the guide roll relative to the surface M1 of the cloth belt stretched between the second stage pressure roll 2- and the first stage pressure roll 2-. This is the angle formed by the surface M2 of the cloth belt stretched between the first stage pressure roll 2- and the guide roll 9 with respect to the surface M1 of the cloth belt stretched between the first stage pressure roll 2- and the guide roll 9. When the first stage pressure roll is moved to the guide roll side on the circumferential surface of the main roll as shown by the chain line and separated from the second stage pressure roll 2-, the wrapping angle changes and α is smaller than 1 . Assuming that α is 2 and the tension of the cloth belt is constant, the pressing force becomes small.

I can do it. In this case, the pivot point P 1 of the extension piece of each bearing on the side wall is offset from the center of the main roll, but the axis of each roll is supported by the bearing so that it can move toward and away from the main roll. There is no problem as many times. However, if necessary, the pivot point P1 may be aligned with the axis of the main roll, and in this case, the distance that the pressure roll can move toward and away from the main roll may be small.

ルで明らかな様に押付力は小さくなる。 The bearing of the pressure roll 2-n in the final stage is the support piece 10.
The lower end of the support piece 10 is fixed immovably, and the upper end of the support piece 10 is pivotally attached to a movable piece 11 provided on the side wall 7 so as to be movable toward and away from the main roll, and is swingably suspended. The movable piece 11 includes, for example, a screw shaft 1 fixed to each side wall 7 in a direction toward and away from the main roll.
2 are screwed together, and when the screw shaft 12 is turned in the forward and reverse directions, it moves forward and backward on the side wall, approaching or away from the Mayroll. This final stage pressure roll is pressed against the main roll as the cloth belt returns in a folded manner, and the pressing force is determined by the tension of the cloth belt and the direction of the support piece, i.e. the movement of the support piece as shown in Figure 3. The angle formed by the cloth belt stretched between the final stage pressure roll and the pressure roll 2n-1 in front of it with respect to the imaginary line L1 connecting the pivot point P2 of the piece and the axis of the final stage pressure roll (wrapping angle α 3 ), when the moving piece leaves the main roll and the pivot point P 2 moves to P′ 2 and moves away from the main roll, the imaginary line changes to L′ 1 and the wrapping angle becomes α 3 ′ becomes small, and as is clear from the vector shown in the figure, the pressing force becomes small.
従つて、この最終段加圧ロールの押付力は一般
的にそれより前のどの加圧ロールよりも大きくす
るが、その値は支持片の枢着支点P2の位置をメイ
ンロールに対して適切に定め、最適に選ぶことが
できる。 Therefore, the pressing force of this final stage pressure roll is generally larger than that of any previous pressure roll, but the value is determined by adjusting the position of the pivot point P2 of the support piece appropriately relative to the main roll. can be determined and selected optimally.
尚、布ベルトの循環速度は約0.2〜4.0m/mi
