脱水には満足できぬ点が残されていた。(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 provided immediately 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, for example, Japanese Patent 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. When the sludge is removed, the sludge tends to flow laterally of the belt and escape, which is a so-called side leak. In addition, in such conventional belt press machines, if the lower belt is made coarse in order to perform sufficient gravity dewatering, sludge will leak out during pressurization, so a fine belt with relatively low air permeability must be used. without getting
Furthermore, since the belt speed is determined based on the pressure zone as a standard, the effect of the gravity dewatering zone has to be insufficient. In addition, in order to reduce the moisture content of the dehydrated cake, a high-pressure type belt press machine is also known, as shown in Japanese Patent Publication No. 15292/1983, in which high pressure is applied by pressure bands from the outside of the upper and lower belts. However, applying high pressure to a dehydrated cake with high moisture content only causes side leaks, so it was still not possible to obtain a sufficient effect for dewatering sewage sludge. In this way, in high-pressure belt press machines, it is necessary to remove water and remove soot to make it non-flowable in the front stage, so draining water in the front stage is even more important than in regular belt press machines. It is. As shown in Japanese Patent Publication No. 60-36880, a belt press machine was proposed in which the gravity dewatering zone was extended and a baffle plate was installed above the zone to separate the sludge. However, such panful plates move laterally and easily lift up from the belt surface when they hit fibrous lumps in the sludge.
The effect of promoting water drainage by exposing the belt surface was still insufficient, and there remained unsatisfactory dewatering of sewage sludge containing a lot of fiber such as lint and hair.

) The sludge supply chute (2) is inclined upward with respect to the direction of movement of the belt to form a sludge supply section (3), and the sludge supply section (3) is formed at the sludge supply chute (2), which is horizontal and extends at least half the length of the main body. The length part is a drainage zone (4).

ことが好ましい。As shown in an enlarged view in FIG. 2, a large number of cylindrical plows (5) made of synthetic resin or the like are arranged in a staggered manner on the upper surface of the draining belt (1) of the draining zone (4). Each plow (5) is supported by a vertical shaft (6) hanging from a frame (not shown) so that it can rotate and move up and down, and the bottom surface is always in contact with the belt surface due to its own weight, but it is necessary. In some cases, 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).

) 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. In the illustrated embodiment, a plurality of plows (5) are installed in a line at regular intervals in the width direction of the belt, and three rows of plows (5) are provided in the belt traveling direction. The mounting positions of the second and third row plows are the plows (5) and (5) of the previous row, respectively.
) are arranged in a staggered manner. However, the number of plows (5) and the number of rows are not limited to those in this embodiment. Since the draining belt (1) is driven independently of the main body, the gutter speed can be adjusted independently of the heald speed of the main body, and it can be operated at an efficient speed according to the state of draining the sludge.

なる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, the sludge that has been flocculated in advance with a polymer flocculant is fed from the sludge supply section (3) to the drain bell).
When supplied to the surface of (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 long as described above, the free water remaining in the sludge is further gravity dewatered. This drainer bell l-1) has an air permeability of 10,000~
Since it is made of a relatively coarse filter cloth with a capacity of 20,000 cc/cJ·min, the water removal effect is high and free water is quickly removed. Note that if the permeability is less than this range, this water removal effect will be insufficient, and if it is greater than this range, sludge will tend to leak, which is not preferable. In addition, cylindrical plows (5) arranged in a staggered manner on the surface of this draining belt (1) plow through the sludge, creating ridges in the flow direction and exposing the surface of the draining belt (1), further promoting dewatering. At the same time, the plow (5) in the next row plows back the furrow created by the plow (5) in the previous row to create a new furrow, and the plow (5) in the next row further plows this furrow. Since the sludge is returned, the entire sludge is uniformly stirred by the plows (5) arranged in a staggered manner, and water is completely removed. At this time, each plow (5) is supported by the vertical shaft (6) so that it can rotate and move up and down, so even if the fibrous material in the sludge gets caught, it will rotate due to the resistance and remove the fibrous material caught on the front side. Since each plow (5) is always in contact with the belt surface of the draining belt +1) due to its own weight, it is highly effective in exposing the belt surface, especially at the bottom end. (8), the plow (5) can be pressed against the belt surface using the flow of sludge.
An excellent draining 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.

) is leveled to a uniform thickness by the pressure cloak (1)), and is gradually pressurized by the weight of the cloak and dehydrated. At this time, the sludge has already lost its fluidity, so side leaks will not occur. Next, the sludge is transferred to the pressurized zone (1
At step 6), as it moves between the zigzag rows (15) while being held between the lower belt 0 and the upper belt (14), it is gradually pressurized more strongly and is sufficiently dehydrated. The sludge is then pulled at a higher pressure by the greater tension of the pressure band (17) in the squeezing zone (20) and is removed by the scraper (21) as a dewatered cake with very low moisture content.

This is a belt press machine with a draining zone formed by a coarse draining belt with an air permeability of ~20,000 cc',/cat・min and a specially shaped plow, and the action of both provides extremely excellent draining. It is effective. A belt press machine equipped with such a draining zone is able to drain the sludge sufficiently in this zone and send the sludge, which has lost its fluidity, to the following wedge zone, pressurizing zone, squeezing zone, etc., in order. It is possible to dewater even sewage sludge, which is fibrous and water-based, at high pressure and obtain a dehydrated cake with a low moisture content without causing side leaks as in the conventional method. Furthermore, since the present invention does not have a zero central arrangement of side leaks, it has the advantage that the amount of sludge supplied can be increased compared to the conventional method, and the throughput can be increased. Therefore, the present invention is a belt press machine that eliminates the conventional problems.
The contribution to industrial development is extremely large.
