(Prior technology) Various types of filter presses have been used for pressurized dehydration of sewage sludge, etc., but in recent years, single filter cloth running type, which has a simple structure, large processing capacity, and is large and lightweight, has been used. Filter presses are widely used. However, in such a single filter cloth running type filter press, many independent filter cloths are stretched around the filter plate, so the tension must be adjusted for each filter cloth to absorb the elongation of the filter cloth. mechanism is required. For example, in the filter press disclosed in Japanese Utility Model Publication No. 59-33446 filed by the present applicant, the roller 51 for running the filter cloth 50 moves in accordance with the elongation of the filter cloth 50 as shown in FIGS.
Using a tool, adjust the position of the elongated hole 53 of the bracket 52.
The structure is such that the position of the sprocket 55 is similarly adjusted and fixed along the elongated hole 56 according to the elongation of the chain 54, so if there are a large number of filter plates, The drawback was that it required a huge amount of maintenance work. Furthermore, Japanese Utility Model Application Publication No. 58-91405 discloses a tension adjustment device in which a roller for running a filter cloth is supported by an elastic means such as a spring. It is difficult to maintain the tension at the same tension throughout the entire stroke, and a large and complicated tension adjustment device is required to maintain the tension approximately constant. It was hot.

(Embodiment) Next, the present invention will be explained in more detail with reference to the illustrated embodiment. 1 shows a large number of filter plates (only 5 filter plates are shown for simplification in the drawing) provided between the fast head 2 and the loose head 3. ), 4 is a stand-alone filter cloth stretched independently around each filter plate 1;
Reference numeral 5 denotes a chain for driving a filter cloth, which is stretched on the side of each filter plate 1. The filter cloth 4 is stretched between an upper roller 6 and a lower roller 7, and the chain 5 has an upper sprocket 9 driven by a spline shaft 8 and a bracket 10 projecting below the filter plate 1. The lower sprocket 11 is supported by the lower sprocket 11. The chain 5 and the filter cloth 4 are connected by a filter cloth drive bar 12, and the filter cloth 4 is reciprocated around the filter plate 1 by the chain 5.

As clearly shown in FIG. 2, in the present invention, the shaft 13 which rotatably supports the lower roller 7 for running the filter cloth is supported in the elongated hole 14 of the bracket 10 so as to be movable up and down. The lower roller 7 and the shaft 13 are designed to have a weight of about 5 to 25 kg, taking into account the weight of the dehydrated cake adhering to the filter cloth 4, so that they themselves function as a weight.
As a result, the filter cloth 4 is always pulled downward by a constant gravity regardless of its elongation, and a constant tension is always applied to the filter cloth 4. Note that the length of the elongated hole 14 may be made to correspond to the maximum amount of elongation of the filter cloth 4, and the shaft 13 and the elongated hole 14 may be non-circular as in the embodiment.

On the other hand, in the present invention, the shaft 15 of the lower sprocket 11 for tensioning the chain 5 is also supported in the elongated hole 16 of the bracket 10 so as to be able to rise and fall freely, and an elastic member 17 such as a spring is attached to the tip of the shaft 15.
A tension mechanism 18 is installed. That is, a rod 19 extending downward is provided at the tip of the shaft 15, and this rod 19 passes through the protrusion 20 of the bracket 10, extends further downward, and connects the spring seat 21 at the lower end and the lower surface of the protrusion 20. an elastic member 1 such as a compression spring between
7 is installed. This elastic member 17 is connected to the rod 1
A downward force is constantly applied to sprocket 9, and as a result, chain 5, which is stretched on sprocket 11, is subjected to tension. As mentioned above, it is difficult for this type of tension mechanism 18 to maintain a constant tension over a wide range, but the elongation of the chain 5 is about 0.5% of the circumference, and the elongation of the sprocket 11 from the top and bottom is limited. Since the amount of movement does not exceed 10 mm, the tension of the chain 5 is kept almost constant by the tension mechanism 18 using the elastic member 17.

(Function) The filter press configured as described above moves the loose head 3 to close each filter plate 1, and causes the filter cloths 4 stretched around the filter plate 1 to come into close contact with each other to form a filter chamber. The stock solution is poured into this filter chamber, compressed, and dehydrated. After that, the filter plate 1 is opened and the filter cloth 4 is passed through a string-like medium 5 such as a chain as shown by the arrow in FIG. Run and dehydrate cake 3
0 is discharged. During this time, the filter cloth 4 and the string-like medium 5 such as a chain are gradually stretched, but since a constant tension is always applied to the filter cloth 4 due to the weight of the lower roller 7 itself, the rate of stretching is 2 of the circumference. %, the tension remains constant.
Furthermore, since the elongation rate of the chain, etc. is less than 0.5% of the circumference, which is much less than the elongation rate of the filter cloth 4, the tension mechanism 18 using the elastic member 17
This makes it possible to keep the tension almost constant. In this way, the tension adjustment device of the present invention is a combination of a weight type tension mechanism and an elastic type tension mechanism, respectively, corresponding to the characteristics of the filter cloth 4 having different elongation rates and the string-like medium 5 such as a chain. The tension between the filter cloth 4 and the string-like medium 5 such as a chain can be kept constant both when the cloth runs and when the filter plate is opened and closed.

(Effect of the invention) As is clear from the above explanation, the present invention combines a tension mechanism that corresponds to the difference in elongation between the filter cloth and the chain, so that the filter cloth can be It is possible to always apply a constant tension to a string-like medium such as a chain.
Furthermore, according to the present invention, it is possible to design the tension adjustment mechanism compactly, and even when there are a large number of filter plates, it is easy to keep the tension of each filter cloth, each chain, and other string-like media constant. This has the advantage of requiring almost no maintenance effort.
Therefore, the present invention has extremely great practical value as a tension adjustment device for a single filter cloth traveling type filter press, which eliminates the problems of the conventional method.
