されていた。(Prior art) A belt press machine is suitable for dewatering pulp waste mud, etc., and dewaters the workpiece while it runs with the workpiece sandwiched between an upper belt and a lower belt that are passed between many rollers. Traditionally known as. However, conventional belt press machines have a structure in which a pressure zone is immediately provided after an extremely short gravity dewatering zone and a wedge zone in which the interval between the upper and lower belts is gradually narrowed, as shown in Japanese Patent Application Laid-open No. 48-74656. In particular, in the case of sludge that contains a large amount of water and is difficult to dewater, such as sewage sludge, which contains a large amount of water and has a high organic content, water is not drained sufficiently in the gravity dewatering zone, and pressure is applied in the pressurizing zone. The disadvantage is that sludge tends to flow laterally of the belt and escape when the belt is removed, a so-called side leak. In addition, in such a conventional belt press machine,
If the lower belt is made coarse in order to perform sufficient gravity dewatering, sludge will leak during pressurization, so a belt with relatively low air permeability and fine mesh must be used, and the belt speed is also lower than the pressure zone. Since it has been established as a standard, the effect of the gravity dehydration zone has inevitably been insufficient. In addition, in order to reduce the moisture content of dehydrated cake,
As shown in Publication No. 15292, a high-pressure type belt press machine is known in which high pressure is applied from the outside of the upper and lower belts using pressure bands, but even when high pressure is applied to a dehydrated cake with high moisture content, side leaks occur. Therefore, it was not possible to obtain a sufficient effect for dewatering sewage sludge. In this way, in a high-pressure belt press machine, it is necessary to remove as much water as possible in the front stage to make it non-fluid, and draining the water in the front stage is even more important than in a normal belt press machine. Therefore, as shown in Special Publication No. 60-36880,
A belt press machine was proposed in which the gravity dewatering cake was extended and a buttful plate was installed above the cake to separate the sludge. However, such a buttful plate has a structure that easily lifts from the belt surface when it comes into contact with fibrous lumps in the sludge, so the effect of exposing the belt surface and promoting water drainage is still insufficient. There were some unsatisfactory points in the dewatering of sewage sludge, which contains a lot of fiber such as lint and human hair.

It was developed with the aim of producing a belt press that can produce dehydrated cakes with low moisture content.

運転することができる。 In Figure 1, 1 has an air permeability of 10,000 to 20,000 c.c./
It is an endless draining belt made of relatively coarse filter cloth of cm 2 .cm, and 2 is a sludge supply chute for supplying sewage sludge, etc. to the upper surface of the belt. The drainage belt 1 has a sludge supply chute 2 which is inclined upwardly with respect to the direction of movement of the belt to form a sludge supply section 3, and a horizontal section extending at least half the length of the main body. Drain the portion Zone 4
It is as follows. On the upper surface of the draining belt 1 in the draining zone 4, a large number of cylindrical plows 5 made of synthetic resin or the like are arranged in a staggered manner, as shown in an enlarged view in FIG. Each plow 5 is rotatably and vertically movably supported by a vertical shaft 6 hanging from a frame (not shown), and normally the bottom surface is in contact with the belt surface due to its own weight, but when necessary, the vertical shaft 6 It is preferable to form a large diameter portion 7 at the lower end of the vertical shaft 6 so that it can be lifted together with the vertical shaft 6.
Further, at the lower end of each plow 5, a truncated conical collar 8 is provided.
It is preferable to form a belt so that when the plow 5 pushes through the sludge, the plow 5 receives a downward force from the sludge and is pressed against the belt surface.
Since the draining belt 1 is driven independently of the main body, its speed can be adjusted independently of the belt speed of the main body, and it can be operated at an efficient speed according to the state of draining the sludge.

たり設けられた洗浄ノズルである。 Reference numeral 9 denotes a guide chute for guiding the drained sludge falling from the rear end of the drainer belt 1, and 10 denotes a lower belt provided below the drainer belt 1. The lower belt 10 has an air permeability of 5000 to 10000 c.c./
It is an endless belt made of a relatively fine-mesh filter cloth of cm 2 cm, and above it is first a pressure mat 11 made of a rubber plate, etc., whose base end is pivotally supported by a horizontal shaft 12, and whose free end is supported by a horizontal shaft 12. It is provided hanging down by its own weight on the lower belt 10, and the lower belt 10 and the pressure mat 11 form a wedge zone 13. This pressurizing mat 11 uses its own weight to pressurize the sludge transferred on the lower belt 10 to a uniform thickness, and the pressurizing effect can be increased by making the free end thicker or adding weight. can.
Next to this wedge zone 13, there is provided a pressure zone 16 in which a lower belt 10 and an upper belt 14 are stretched between a number of rollers 15 arranged in a zigzag pattern, and the sludge is dehydrated by belt tension. ing. As shown in the figure, the diameter of these rollers 15 is gradually reduced to increase the contact pressure, and each roller 15 is made of a steel pipe with many holes or a cylindrical shape made by winding punched metal. It is preferable to enhance the dehydration effect. Reference numeral 17 denotes a squeezing means using a pressure band having a higher tension than the upper belt and the lower belt, which is stretched between three rollers 19 outside the large diameter roller 18 next to the pressure zone 16. Squeezing means 17 using this pressure band
is made of stainless steel, polyester resin, etc., and forms a compression zone 20 in which the sludge is pressed under high pressure by strongly pressing the lower belt 10 and the upper belt 14 against the surface of a large-diameter roller 18. . The squeezing means in this embodiment is a pressure band, but other means such as a method of pressing a roller, a method of pressing with a caterpillar plate, a method of pressing the sludge with a flexible diaphragm, etc. may be used. The large diameter roller 18 is rotated by a drive device (not shown), and the pressure band is the lower belt 10.
The upper belt 14 is pressed against the large-diameter roller 18 and runs as the large-diameter roller 18 rotates. In addition, 21 is a resin or metal scraper for peeling the dehydrated cake from the lower belt 10 and the upper belt 14, and 22 is a scraper for cleaning the draining belt 1, the lower belt 10, and the upper belt 14 after the dehydrated cake has been peeled off. The cleaning nozzle is installed across the entire width of the belt.

ものであるからベルト面を傷付けることはない。(Function) With this structure, if sludge that has been flocculated in advance with a polymer flocculant is supplied from the sludge supply section 3 to the relatively coarse surface of the draining belt 1,
The free water is gravity dewatered on the inclined belt surface and only the sludge is sent to the drainage zone 4. Since the drainage zone 4 is made long as mentioned above, the free water remaining in the sludge is further dehydrated by gravity, and the cylindrical plows 5 arranged in a staggered manner on the surface plow through the sludge. Since ridges are formed in the flow direction to expose the surface of the draining belt 1, dewatering is promoted, and the staggered arrangement uniformly stirs the entire sludge and drains the water throughout. At this time, each plow 5 is supported by a vertical shaft 6 so that it can rotate and move up and down, so even if the fibrous material in the sludge becomes clogged, the plow rotates due to the resistance and moves the fibrous material stuck to the front side backward. Moreover, since each plow 5 is always in contact with the belt surface of the draining belt 1 due to its own weight, the effect of exposing the belt surface is high. The formed belt can use the flow of sludge to press the plow 5 against the belt surface, so that the most excellent effect can be obtained. However, since the plow 5 is made of a light material such as synthetic resin and has a small coefficient of friction, it will not damage the belt surface.

２１により取出されることとなる。 The sludge, which has been sufficiently gravity dewatered and concentrated in the drainage zone 4, then falls onto the lower belt 10 via the guide chute 9, and is smoothed to a uniform thickness by the pressure mat 11 in the wedge zone 13. The weight of the mat gradually pressurizes it and dehydrates it. At this time, the sludge has already lost its fluidity, so side leaks will not occur.
The sludge is then transferred to the lower belt 10 in the pressurized zone 16.
As it moves between the zigzag-shaped rollers 15 while being sandwiched between the upper belt 14 and the upper belt 14, it is gradually pressurized more strongly and is sufficiently dehydrated. At this time, since the pressure applied to the surface of the roller 15 due to the tension of the belt is inversely proportional to the diameter of the roller, it is advantageous to gradually reduce the diameter of the roller 15 as in the embodiment. Thereafter, the sludge is further pressed under high pressure by the large tension exerted by the pressure band in the squeezing zone 20, and is removed by the scraper 21 as a dewatered cake with extremely low water content.

ころは極めて大である。(Effects of the Invention) As is clear from the above description, the present invention forms a draining zone by using a coarse draining belt different from the lower belt and upper belt forming the pressure zone and a specially shaped plow. The sludge that has been sufficiently drained in the zone to eliminate fluidity is sent sequentially to the wedge zone, pressure zone, and squeeze zone, eliminating the side leaks that occur in the conventional method, which is difficult to remove due to the high fibrous content. Even dewaterable sewage sludge can be dehydrated under high pressure to obtain a dehydrated cake with low moisture content. Further, the present invention has the advantage that the amount of sludge supplied can be increased compared to the conventional method, and the throughput can be increased since there is no fear of side leaks. Therefore, the present invention greatly contributes to the development of industry as a belt press machine that eliminates the problems of the conventional belt press.
