みだしくサイドリーク）が発生する等の問題があった。As a device for dewatering various types of sludge, a pair of endlessly connected belt-like furnace cloths are wound around a number of rollers and moved in opposite directions, and the sludge is sandwiched between the belt-like furnace cloths.
A belt press type dehydrator that performs dehydration by squeezing is known, and conventionally, a monofilament fabric made of synthetic fibers has been used for the furnace cloth. However, recent belt press type dehydrators have a mechanism that applies high tension to the furnace cloth, a pressure belt mechanism that presses another belt on the outside of the furnace cloth,
Or equipped with a filter press mechanism, which can handle 10 kg of sludge/
Since it has come to be squeezed at a pressure higher than Cl#, the above-mentioned monofilament fabric? P cloth had the drawback that the high-pressure sludge clogged the fabric, resulting in clogging, and that the cake could not be peeled off. In order to eliminate this drawback, attempts have been made to use thin monofilament threads in the warp and weft of the ill tF fabric to densify the structure and smooth the surface, but in this case, gravity removal There were problems such as poor dewatering, resulting in protruding sludge and side leaks.

じた。On the other hand, in order to improve the peeling of the cake, one of the pair of oven cloths is made of synthetic fiber! #! The other side is made of woven fabric.
It has been proposed to use a felt fabric in which a fine denier polyamide fiber web is layered on a tS fabric and bonded by needling (see Japanese Patent Laid-Open No. 103797/1983). In this case, negative pressure is generated inside the cake and felts 1 to 1 to 2 immediately after passing through the nip point between the rotating drum and the pressing roller, but of these negative pressures, the negative pressure inside the cake is due to the felt or the right side. Since the negative pressure in the direction is larger than the negative pressure in the direction, a part of the furnace liquid is called back from the felt furnace cloth side to the cake side by the above negative pressure and capillary action and moves to the boundary between the two, helping to peel off the cake. . However, as shown in FIG. 1, the above-mentioned conventional felt kiln cloth consists of a base fabric 3 woven using warp yarns L and weft yarns 2, and a web 4 made of one type of fine denier polyamide fiber. Since the upper layer felt portion 6 made of only polyamide fibers is formed on the base fabric layer portion 5 made of the base fabric 1 and polyamide fibers by bonding by needling, the base fabric below this upper layer felt portion 6 The layer portion 5 has a denser structure, and filtration is controlled by the base fabric layer portion 5, so that solids in the sludge accumulate in the upper felt portion 6, which has a relatively coarse structure, and clogging progresses. In addition, since the back surface of the felt furnace cloth, that is, the back surface of the base fabric layer portion 5, is formed relatively smooth and its unevenness is small, when a plain roller with a smooth surface is used as the pressing roller,
The back side of the felt oven cloth was in close contact with the surface of the pressing roller, and there was no place for the oven liquid to escape, resulting in an inconvenience in that too much water was recalled and the moisture content of the cake increased.

機用フェルト炉布を提供するものである。This invention improves the conventional felt furnace cloth described above, thereby providing good cake removal properties by recalling the furnace liquid, and at a pressure of 10 kg/d? Even when sludge is dehydrated under the above high pressure, clogging occurs little, the furnace liquid flows out smoothly even when using a squeezing roller with a smooth surface, and the dimensional stability is good, and the excess sludge The purpose of the present invention is to provide a felt furnace cloth for a belt press type dehydrator that is effective even for sludge that is highly viscous and difficult to filter, such as sludge.

A thick denier thermoplastic synthetic fiber web and a fine denier thermoplastic synthetic fiber web are woven using a monofilament yarn of synthetic fiber in at least one of the webs, and the thermoplastic synthetic fiber web is layered on the base fabric layer in order. Bell 1-Press type dehydration characterized in that the upper felt portion is composed of two types of fine denier thermoplastic synthetic fiber web and is formed into a denser structure than the base fabric layer portion containing the above-mentioned base fabric. This is felt kiln cloth for machines.

離性を一層向上することができる。A double weave base fabric 13 is woven by the warp yarns 11 and the weft yarns 12, and a comparatively thick synthetic fiber web 14 is layered on top of this base fabric 13 and bonded by needling. The fine denier synthetic fiber webs 15 are overlapped and bonded by needling again, and as a result of their entanglement, the base fabric layer portion 16 is formed in order from the bottom.
, a lower felt portion 17 and an upper felt portion 18 are formed. At this time, the structure is such that the upper felt portion 18 is the densest and the base fabric layer portion 16 is the coarsest,
The inter-fiber voids are increased in the order of the upper felt portion 18, the lower felt portion 17, and the base fabric layer portion 16, so that the sludge is captured in the upper felt portion 18, and the solid matter that has passed through the upper felt portion 18 is transferred to the lower felt portion. 17 and base fabric layer portion 16. Therefore, the solid content that has passed through the upper felt portion 18 is
Most of them are the lower felt part 17 and the base fabric layer part 16
are passed through together with the furnace liquid, so that the above-mentioned solids do not accumulate in these parts and cause clogging. and,
When the upper layer felt portion I8 becomes clogged, the solid matter can be removed by washing and it can be easily restored. In addition, the upper felt portion 18 and the lower felt portion 17
The presence of the felt cloth has a recall effect similar to that of conventional felt oven cloth, so that the cake can be easily peeled off. In addition,
By using polyamide fibers with good hydrophilicity as the synthetic fibers constituting the upper layer 1 to 18, the cake releasability can be further improved.

を一層良好にすることができる。The base fabric 13 described above is woven into a relatively coarse net-like structure using monofilament yarns of synthetic fibers as at least one of the warp yarns 11 and the weft yarns 12. In particular, a relatively thick denier synthetic fiber monofilament yarn is used for the weft 12,
It is preferable to use thin monofilament twisted yarns as the warp yarns 11, thereby increasing the rigidity of the base fabric 13, withstanding high tension during use, and maintaining good dimensional stability. 16 is made relatively coarse to facilitate the passage of the furnace liquid, and the back surface of the felt cloth is made large to prevent it from coming into close contact with the squeezing roller, and is interlaced with the thick denier synthetic fiber web 14 above. strengthen the
Furthermore, breakage of the needle during needling can be prevented. On the other hand, when monofilament yarn is not used, the base fabric 13 lacks rigidity, lacks dimensional stability, stretches in the length direction and contracts in the width direction during use, and dehydration conditions fluctuate. Since the back surface of the kiln cloth becomes smooth on the felt 1, it comes into close contact with the surface of the squeezing roller, causing problems such as the kiln liquid not being discharged.On the other hand, when only monofilament yarn is used, the bonding force with the synthetic fiber web 14 is reduced. This weakens the needle and increases the chance of needle breakage during needling. Incidentally, by using filament yarns of polyester fibers for the warp threads 1 and weft threads 12, the dimensional stability of the felt kiln cloth can be further improved.

ちろんである。As explained above, this invention uses monofilament yarns of synthetic fibers for the warp or weft of the base fabric, and uses two types of synthetic fiber webs with different thicknesses for the synthetic fiber web, and has a dense upper layer felt portion. Since it is formed into a structure, the cake peelability is good due to the recall effect of the furnace liquid, and even when dehydrating at a high pressure of 10 kg/c+j or higher, there is little clogging, and it has excellent dimensional stability. Furnace fluid flows out smoothly even when using a squeezing roller with a smooth surface. Therefore, the particle size of digested and washed sludge, surplus sludge, raw sludge, putrefaction sludge, etc. is small, and the concentration is 2.
．． It can also be used for dewatering highly viscous and difficult-to-pass sludge with a crude fiber content of 5% or less. It goes without saying that it can be used for only one or both of the pair of furnace cloths.

。Table 5 Table 6 As can be seen from the table above, in the furnace cloth of Comparative Example 1, when the squeezing roller is a plain roller, there is no place for the furnace liquid to escape and the furnace liquid cannot be sufficiently discharged, so the pressure is not released. When dehydrated, it recalls a large amount of water, increasing the moisture content of the dehydrated cake. On the other hand, in Example 1, since the furnace liquid was discharged smoothly, an appropriate amount of moisture was recalled, and a cake with good peelability and a low moisture content was obtained. This means that
This shows that the rough base layer portion and the lower felt portion act as a furnace fluid drain path. Also, dehydration is about 10k
When carried out at a pressure of g/cJ, the r fabric of Comparative Example 2:
Bleed through of the furnace fluid occurs, making it unusable. In addition, the (r fabric of Comparative Example 1) caused a large amount of clogging, especially in the dense base fabric part, and this clogging did not disappear even after washing, resulting in an extremely low air permeability. Then,
The felt kiln cloth of Example 1 was slightly clogged in the two-layer felt portion, but it was easily restored by washing.
