Therefore, in the case where the endless belt is used in the past, it is difficult and time consuming to suspend the belt, but according to the present invention, the belt can be simply and quickly attached. -7- 200800358 (4) [Embodiment] The filter belt type dewatering apparatus of the present invention is a device in which a slurry-like or sludge-like dewatered material is filtered and dehydrated into a cake having a low water content. Examples of the dehydrated material include, for example, 'the surplus sludge of the food industry, the chemical industry, the product of the metal industry, the waste, the activated residual sludge of the sewage (dirty water), and the domestic wastewater sludge. The basic principle of the φ filter cloth belt type dewatering device is to filter the dehydrated material to be supplied to the filter cloth belt by pressing with a pressure belt or a roller and/or suction at the lower portion of the filter cloth belt. The dehydrated dehydration unit is subjected to dehydration treatment of the slurry-like or sludge-like dehydrated portion, and various methods may be employed in which the dehydrated material is sandwiched between the two filter cloth belts or the filter cloth belt. A method of performing pressure dehydration with a pressure belt, or a method of dehydrating by using a single filter cloth belt by pressing with a roller or suction from a lower portion of the filter cloth belt. The filter tape type dewatering apparatus of the present invention comprises: a filter cloth tape wound around the dewatering device; and a dewatering portion. The dewatering unit is a member that filters and dehydrates the dehydrated material to be supplied onto the crepe belt by pressing with a pressure belt or a roller and/or suction from a lower portion of the filter cloth belt. A processed material collecting unit, a washing unit, a pressing unit, and the like are provided. As an example of the filter belt type dewatering apparatus of the present invention, as shown in Fig. 1, the filter belt type dewatering apparatus is a vacuum dewatering unit, a pressurized dewatering and transferring unit, a processed material collecting unit, a washing unit, and a pressing unit. Each of the portions of the portion is formed such that a single seamed filter cloth belt formed by joining the ends of the endless belt continuously travels in the above-mentioned respective portions in the order of -8-200800358 (5). In Fig. 1, a filter cloth tape 1 is wound around a negative pressure dewatering unit 3, a pressurized de-β water transfer unit 4, a processed material recovery unit 5, a cleaning unit 6, and a pressing unit 7. The negative pressure dewatering unit 3 is a member that is supplied to the upper surface side of the filter cloth belt 1 and that is subjected to suction negative pressure from the lower surface side of the filter cloth belt 1 to perform initial dewatering of the dehydrated material S. The pressurized dehydration/transfer unit 4 is a process in which the dehydrated material S having undergone initial dehydration is pressed and dehydrated together with the filter cloth belt φ 1 in the upper and lower pair of press rolls 4Α and 4, and the dehydrated material is dehydrated. C is transferred to the upper punching top roller 4Α, the member which is peeled off by the filter cloth 1; the processed material recovery part 5 is a member which scrapes off and collects the processed material C which is transferred to the upper punching top roller 4Α; The cleaning unit 6 is a member that cleans the filter cloth tape 1 from which the treatment C has been peeled off, and the pressing portion 7 is a member that throttles to obtain purified water. By using the filter belt type dewatering apparatus configured as described above, first, the dewatered material S is supplied to the upper side of the filter cloth belt 1 which is conveyed in the direction of the arrow by the supply tank 2 disposed in front of the negative pressure dewatering unit 3. . In the negative pressure dewatering section, the negative pressure is applied to the dehydrated material by the lower side of the filter cloth, and the moisture of the dehydrated material is sucked to the lower surface side of the filter cloth to perform initial dehydration of the dehydrated material S. . Next, the press-rolling top roller 4Α and the press-bottomed roller 4Β of the pressurization dehydration and transfer unit 4 pressurize and dehydrate the dehydrated material which has undergone initial dehydration together with the filter cloth belt, and transfer the dehydrated processed material. After the upper punching top roller is 4 turns, it is peeled off by the filter cloth tape. Then, in the processed material collecting unit 5, the processed material transferred to one of the press rolls 4A is scraped off and collected by the doctor blade 5, and the dehydrated material is used as a cake having a low water content of -9-200800358 (6) The processed material C is separated and recovered to the recovery tank 5B. Further, the filter cloth strip from which the treated material has been peeled off is washed in the cleaning unit 6, by the cleaning tank-6A, the shower tubes 6B, 6C, and then a pair of press-squeezing rollers 7A of the pressing portion 7. 7B, the water is extruded, returned to the supply tank 2, and a new dehydrated material S is supplied. In the present invention, the filter belt type dewatering apparatus is used as a filter cloth belt, and an open belt is used for the ease of the hanging operation, and the belt is attached to the dewatering apparatus as a joint having an endless shape. The filter cloth is used. The end belt for the filter cloth belt having the seam is as shown in Fig. 2, and a plurality of loops L are provided at the respective ends. As shown in Fig. 3, the filter tape type is composed of a base fabric B of a woven fabric and a two-layer butt layer W. The butt layer W is formed by entanglement of the cotton web fibers laminated on the base fabric B by needle punching. The base fabric B is formed by weaving the wires 21 to 29 in the MD (warp) direction and the wires 11 to 19 in the CD (weft) direction as shown in Fig. 4 . The line in the #MD direction is folded back at the end to form the ring L. In use, an end-shaped thick cloth tape is hung on the dewatering device, the two end portions are butted, and the other end ring is fitted between the rings of one end cloth so that the rings at the both end portions mesh with each other. . This engaging operation is as shown in Fig. 3 (A), and the ends are joined to each other to form a mountain shape, and the rings are engaged with each other. Therefore, when the other ring is fitted between one of the rings, the other ring is fitted between the one side of the ring from the lower side (or, on the contrary, from the upper side to the lower side). Furthermore, in the meshing operation, a dedicated jig is also used. When the ring groups L and L at both ends are engaged, as shown in FIG. 3(B), a tunnel is formed by the hole portion of the continuous ring by using -10-200800358 (7), and the core wire T is inserted into the tunnel. 'By forming a flat shape by butting into the mountain-shaped end, the tape is formed. Between the loops L of the end fabrics provided on one end of the end belt, the loops of the other rams are fitted, and the loops at the ends are chewed to each other, whereby the filter cloth strips having the seams are formed, but The loop L is formed by weaving the wire 29 in the MD direction and the wires 11 to 19 in the CD direction by folding back at the end of the line in the MD direction. That is, as shown in Fig. 4, the folded portion of the MD wire is L by the base fabric woven by the C D wire and the MD wire 21 to. Fig. 5 shows an example of a CD-direction sectional view of the end cloth of the base fabric. In Fig. 5, the MD-direction wires 21A to 29A and 21B to 29B are respectively connected to each other, and are folded back to form a loop L. In the base fabric woven as described above, the vector of the force generated by the weaving of the CD direction wire and the MD square material is opposite to each other in the adjacent MD line. Therefore, the ring group L formed adjacently generates the bit φ in the up and down direction. shift. Therefore, it is not easy to cause the loops at both ends to be engaged with each other by the core wire T. In order to solve this problem, as shown in Fig. 6, it is preferable to use a belt having a full line which is an end edge of the CD wire, and an adjustment wire 3 woven by a woven pattern different from the CD wire. 0, the MD direction wire near the edge of the both ends will not be pushed outward in the outward direction and/or CD to maintain the shape of the ring. Further, as shown in Fig. 7, the filter cloth composed of the base fabric B and the butting layers W1 and W2 formed by needle punching on one or both sides thereof may have a woven fabric having the following structure, that is, the base portion. Rings L1 and L2 at both ends are used. The filter is formed into a 21~ material 1 1~ ring. In the direction of the end-line reverse bias, the direction is made by the core -11 - 200800358 (8) line T, the seam of the wing portion (W1 a ) of the butt layer is configured. Thereby, it is possible to protect the seam damage caused by the stamping* from leaking the dehydrated material S supplied to the filter cloth belt. After the loops are formed by the loops at both end portions, the joint portion is formed, and the joint portion is improved. The surface state of the belt is changed, and the seam portion of the belt can be resin-processed. Further, in the case where the seam is covered by the fin portion, the resin processing of the fin portion φ prevents the mating fiber from falling off while the belt is traveling. In the slurry or sludge form of the present invention, the surface treatment of the surface of the filter cloth is not required, and the surface treatment of the resin portion of the smooth portion is not an effective means. The resin to be processed is preferably a urethane, acrylic acid, melamine or synthetic rubber. The filter cloth belt is usually a filter cloth belt having a thickness of 2 to 10 mm and a width of 50,000 to Φ right. As described above, a laminated structure of a general surface layer is used, and the base fabric and the surface layer are borrowed | , the fibers are joined to each other in an entangled manner. The base fabric and the surface layer are selected from various materials depending on the type of the dehydrated material, etc., but the number of intersections of the warp yarn and the weft yarn of the base fabric made of, for example, synthetic fibers is 600 X 5 cm, and the surface layer is The average pore diameter is 100~15 〇// The gravity filter of the filter cloth is improved, and the dimensional stability is improved, and it can be raised to cover the base injury, or the seam with the seam can be smooth, as described above. The sub-division and the surrounding dimension are not dehydrated by the fin portion, so the wing is used for resin oxygen, polyester, 4000 mm left in the base fabric layer by needle punching, moisture content monofilament fiber weaving ~ 1 5 0 0 / 5 cmm, can improve the walking performance -12- 200800358 (9) Further, dehydration can be effectively performed by two or more layers having different laminated denier. As shown in Fig. 8, a three-layered felt material consisting of a three-layer structure having an outer layer 1 1 A constituting the upper surface, an inner surface layer 1 B constituting the lower surface thereof, and an intermediate layer 1 C between the layers is formed. The outer layer 1A is composed of a fine fiber layer for filtering the dehydrated material S, the intermediate layer 1 C is composed of a fine fiber layer for promoting moisture permeation, and the inner layer 1 B is a base cloth for promoting dewatering. The layer is constructed, whereby the filtration to the dewatering φ process can be efficiently performed. Further, fine particles of the dehydrated material S can be aggregated on the outer layer 1 A. These layers are entangled with each other by a needle punching process or the like. Further, the following base fabric can also be used as a filter cloth, thereby reducing the entry of sludge into the filter cloth and improving the peelability. The cloth is woven with synthetic fiber slab-shaped crimped yarn for the upper weft, synthetic resin monofilament fiber for the lower weft, and synthetic resin monofilament fiber for the warp. • [Industrial use possibility] The present invention is directed to the slurry or The sludge-like dehydrated material is dehydrated into a cake-like dewatering rhodium with a low water content, and a jointed filter cloth belt formed of an open belt is used as a dewatering device for the filter belt. In the conventional filter belt type dewatering apparatus, the filter cloth belt used is often replaced by dirt due to dirt, and the filter cloth belt is long, large, and wide, and is complicatedly wound in the dewatering apparatus, so that it is in the case of an endless belt. The hanging operation is difficult and takes time. According to the present invention, since the filter cloth tape is used as a filter cloth belt having a seam of -13-200800358 (10) formed by an open belt, the hanging operation can be carried out by the hanging belt. Into Since the inside of the water device travels and is engaged in the device, it is possible to easily carry out the 挂 hang operation 'can save the operation stop-time for the device for belt replacement, replacement, etc., and can quickly perform the work. According to this method, the dewatering treatment of the slurry-like or sludge-like dehydrated material in a wide range of fields can be effected.
